Embodiment 1

(23) Unless otherwise specified, the developer cartridge of the embodiment has the same structure with the developer cartridge shown in FIG. 1.

(24) FIG. 4 is a structure diagram of a counting mechanism in the Embodiment 1. The counting mechanism comprises a rotary member 10 and a fixed member 20, wherein the rotary member 10 is provided with a hanging wall 11, protrusions 12 and a cylinder 13; the cylinder 13 comprises an unthreaded portion 13a and a threaded portion 13b; the fixed member 20 comprises a footwall 21 and a screwed hole 22 corresponding to the threaded portion 13b, is fixed on the side wall 58 of the toner hopper 55 of the developer cartridge as shown in FIG. 1, and is motionless relative to the toner hopper 55; and a gear (not shown in the figure) is arranged on the outer circumference of the hanging wall 11 of the rotary member 10 and engaged with the input gear 67, and receives power from the input gear 67 to drive the rotary member 10 to rotate around a central shaft of the hanging wall 11.

(25) When the counting mechanism is on the initial state, the threaded portion 13b on the rotary member 10 is not engaged with or partially engaged with the screwed hole 22 of the fixed member 20. As shown in FIG. 5, a certain distance is maintained between the hanging wall 11 of the rotary member 10 and the footwall 21 of the fixed member 20; the protrusions 12 of the rotary member 10 are extended outwardly in the direction perpendicular to the side wall 58; and the protrusions 12 are in a first position so as to come in contact with the contact lever 86 on the electronic photographing device when the threaded portion 13b and the screwed hole 22 are engaged with each other, thus the counting function of the developer cartridge 28 is realized.

(26) As the gear on the outer circumference of the hanging wall 11 of the rotary member 10 is engaged with the input gear 67, the threaded portion 13b of the rotary member 10 is engaged with the screwed hole 22 of the fixed member 20 when the hanging wall 11 rotates (along the E direction as shown in FIG. 5) after receiving power from the input gear 67. Due to the thread engagement, a downward acting force F along the axial direction of the cylinder 13 is applied to the threaded portion 13b by the screwed hole 22, and the rotary member 10 is driven to move downward (along the F direction as shown in FIG. 5) to be close to the fixed member 20. As the protrusions 12 are extended outwardly in the direction perpendicular to the side wall 58, the protrusions 12 come in contact with the contact lever 86 when the threaded portion 13b is engaged with the screwed hole 22, thus the counting function is realized.

(27) When the threaded portion 13b is not engaged with the screwed hole 22 again, the unthreaded portion 13a comes in contact with the screwed hole 22 (the outside diameter of the unthreaded portion 13a is less than that of the threaded portion 13b and less than the inside diameter of the screwed hole 22 as well), and the acting force in the F direction as shown in FIG. 5 is not applied to the rotary member 10 by the screwed hole 22, thus the rotary member 10 does not move downward again. When the rotary member 10 and the fixed member 20 are on the state as shown in FIG. 6, the space between the rotary member 10 and the fixed member 20 is small or the rotary member 10 and the fixed member 20 are adjacent to each other. Herein, the protrusions 12 on the rotary member 2 10 are in the second position in the direction perpendicular to the side wall 58, so the protrusions 12 on the rotary member 10 cannot come in contact with the contact lever 86 again.

(28) In the embodiment, the width of the hanging wall 11 of the rotary member 10 is small, so when the rotary member 10 moves to the state as shown in FIG. 6, the hanging wall 11 of the rotary member 10 is not engaged with the input gear 67 again; the rotary member 10 does not rotate; the protrusions 12 are not in contact with the contact lever 86; and the counting function of the developer cartridge 28 does not work.

(29) In the embodiment, as a thread pitch is arranged on the threaded portion 13b, the screwed hole 22 is engaged with the unthreaded portion 13a after the one-turn engagement with the threaded portion 13b; the protrusions 12 are only subjected to one rotation along with the rotary member 10; and each protrusion 12 only comes in contact with the contact lever 86 once before rotating from the first position to the second position.

(30) Another aspect of the embodiment is that two or more than two thread pitches are arranged on the threaded portion 13b, thus the screwed hole 22 is engaged with the unthreaded portion 13a after the engagement with the threaded portion 13b for two turns or more than two turns; the protrusions 12 are subject to two rotations or more than two rotations along with the rotary member 10; and each protrusion 12 comes in contact with the contact lever 86 twice or more than twice before rotating from the first position to the second position.

(31) Another aspect of the embodiment is that the width H of the hanging wall 11 of the rotary member 10 or the width of the input gear 67 can be set to be large enough to drive the rotary member 10 to be always engaged with the input gear 67 during the downward movement. Moreover, when the rotary member 10 is on the state as shown in FIG. 6, the gear on the outer circumference of the hanging wall 11 is still engaged with the input gear 67 when the threaded portion 13b is not engaged with the screwed hole 22, and the rotary member 10 still rotates, namely the rotary member 10 always rotates during the whole working process of the developer cartridge 28.

(32) Another aspect of the embodiment is that a gear is not arranged on the rotary member 10 to be engaged with the input gear 67, and a power component is arranged on the rotary member 10 to drive the rotary member 10 to rotate. For example, a torsion spring is arranged on the rotary member 10 to provide power to the rotary member 10.

(33) In the embodiment, the elastic component 30 in contact with the rotary member 10 is also adopted, wherein a downward acting force along the direction as shown in FIG. 5 is applied to the rotary member 10 by the elastic component to help the threaded portion 13b of the rotary member 10 be in better engagement with the screwed hole 22 of the fixed member 20.

Embodiment 2

(34) The FIGS. 7 and 8 illustrate the Embodiment 2. Unless otherwise specified, the developer cartridge of the embodiment has the same structure with the developer cartridge of the Embodiment 1.

(35) The counting mechanism of the embodiment comprises a rotary member 10a and a fixed member 20a, wherein the rotary member 10a is provided with a hanging wall 14, protrusions 15 and a screwed hole 16; a footwall 23 and a cylinder 24 are arranged on the fixed member 20a; the cylinder 24 comprises a threaded portion 24a and an unthreaded portion 24b; a gear is arranged on the outer circumference of the hanging wall 14 of the rotary member 10a and engaged with the input gear 67; and the fixed member 20a is arranged on the side wall 58 of the toner hopper 55 and is motionless relative to the toner hopper 55.

(36) FIG. 7 is a schematic diagram of the counting mechanism of the embodiment on the initial state. Herein the protrusions 15 on the rotary member 10a are extended out of the side wall 58 and can come in contact with the contact lever 86 on the electronic photographing device when the threaded portion 24a is engaged with the screwed hole 16, thereby the counting function of the developer cartridge is realized.

(37) FIG. 8 is a schematic diagram of the counting mechanism of the embodiment on the final state. Herein the threaded portion 24a is not engaged with the screwed hole 16 which rotates around the unthreaded portion 24b, and the protrusions 15 are not extended out of the side wall 58 and are not in contact with the contact lever on the electronic photographing device, thereby the counting function of the developer cartridge does not work.

(38) It is obvious to those having ordinary skill in the art that the working process and working principle of the counting mechanism of the embodiment are the same with those of the Embodiment 1; and no further detailed description is given herein.

Embodiment 3

(39) Unless otherwise specified, the developer cartridge of the embodiment has the same structure with the developer cartridge shown in FIG. 1.

(40) As illustrated in FIG. 9, the counting mechanism of the embodiment comprises a rotary member 10b and a fixed member 20b, wherein the rotary member 10b comprises a hanging wall 17, protrusions 18 and a support pillar 19; the fixed member 20b comprises a footwall 25 and an opening 26, is fixed on the side wall 58 of the toner hopper 55, and is motionless relative to the developer cartridge 28; a gear is arranged on the outer circumference of the hanging wall 17 of the rotary member 10b and engaged with the input gear 67 of the developer cartridge; and the rotary member 10b can rotate clockwise around the center of the hanging wall 17 (along the G direction as shown in FIG. 9).

(41) FIGS. 9 and 10 are schematic diagrams of the counting mechanism of the embodiment on the initial state. When the counting mechanism is on the state, the protrusions 18 on the rotary member 10b are in the first position in the direction perpendicular to the side wall 58. As the protrusions 18 on the rotary member 10b are extended outwardly in the direction perpendicular to the side wall 58, the protrusions 18 come in contact with the contact lever 86 on the electronic photographing device in the rotation process, thus the counting function of the developer cartridge is realized.

(42) When the counting mechanism is on the initial state, a certain angle is formed between the support pillar 19 on the rotary member 10b and the opening 26 on the fixed member 20b in a staggered manner, and a certain distance is maintained between the hanging wall 17 of the rotary member 10b and the footwall 25 of the fixed member 20b, as shown in FIG. 10. Therefore, guarantee can be made that the protrusions 18 on the rotary member 10b come in contact with the contact lever 86 in the rotation process of the rotary member 10b.

(43) When the rotary member 10b rotates a certain angle (less than or equal to 360°) along the rotation direction as shown in FIGS. 9 and 10, the rotary member 10b is on the final state as shown in FIGS. 11 and 12. When the rotary member 10b is on the state, the support pillar 19 on the rotary member 10b is over against the opening 26 on the fixed member 20b. Because the support pillar 19 is smaller than the opening 26, the rotary member 10b moves closer to the fixed member 20b (in the H direction as shown in FIG. 11) under the action of an elastic force applied by the elastic component 30b; the protrusions 18 on the rotary member 10b move closer to the side wall 58; the hanging wall 17 of the rotary member 10b and the footwall 25 of the fixed member 20b are adjacent to each other; and the protrusions 18 are in the second position in the direction perpendicular to the side wall 58 and cannot come in contact with the contact lever 86 on the electronic photographing device again, thus the counting function of the developer cartridge does not work.

(44) In the embodiment, the width of the gear on the outer circumference of the hanging wall 17 of the rotary member 10b is very small, so the gear on the outer circumference of the hanging wall 17 is not engaged with the input gear 67 again after the rotary member 10b is close to the fixed member 20b (on the state as shown in FIGS. 11 and 12), thus the rotary member 10b does not rotate again.

(45) Another aspect of the embodiment is that the width of the gear on the outer circumference of the hanging wall 17 can be set to be large enough so that the gear on the outer circumference of the hanging wall 17 can still be engaged with the input gear 67 after the rotary member is on the state shown in FIGS. 11 and 12. The rotary member 10b still rotates on the state shown in FIGS. 11 and 12.

(46) Another aspect of the embodiment is that a gear is not arranged on the rotary member 10b to be engaged with the input gear 67, and a power component is arranged on the rotary member 10b to provide power to the rotary member 10b and to drive the rotary member 10b to rotate. For example, a torsion spring is arranged on the rotary member 10b to provide power to the rotary member 10b.

(47) Another aspect of the embodiment is that the fixed member 10b is arranged on the side wall 58 of the developer cartridge and can rotate a certain angle (such as 60 DEG, 90 DEG, etc.) relative to the side wall 58, and the support pillar 19 is over against the opening 26 after driven to rotate a larger angle (more than 360°).

Embodiment 4

(48) Unless otherwise specified, the developer cartridge of the embodiment has the same structure with the developer cartridge of the Embodiment 3.

(49) In the embodiment, the rotary member 10b is fixed on the side wall 58 of the toner hopper 55 and is motionless relative to the side wall 58; the fixed member 20b can rotate relative to the developer cartridge 28; the fixed member 20b is provided with the protrusions 18 which rotate along with the fixed member 20b; the hanging wall 17 and the support pillar 19 are arranged on the rotary member 10b; the fixed member 20b is also provided with the footwall 25 and the opening 26; a gear is arranged on the outer circumference of the footwall 25 of the fixed member 20b and engaged with the input gear 67; and the protrusions 18 come in contact with the contact lever 86 in the rotation process, thus the counting function of the developer cartridge is realized.

Embodiment 5

(50) Unless otherwise specified, the developer cartridge of the embodiment has the same structure with the developer cartridge of the Embodiment 1.

(51) FIGS. 13, 14, and 15 illustrate the Embodiment 5, wherein a protrusion 12a on the counting mechanism of the embodiment has the structure of an inverted truncated cone. When the rotary member 10 is in downward rotation movement, an inclined plane 12b of the protrusion 12a comes in contact with the contact lever 86 on the electronic photographing device, thus the counting function of the developer cartridge is realized; and when the inclined plane 12b is separated from the contact lever 86, the information detection mechanism 81 on the electronic photographing device is not positioned inside the optical sensor as a barrier again, thus the counting function of the electronic photographing device does not work.

(52) Another aspect of the embodiment is that: the protrusion 12a has a structure of a truncated cone, and an inclined plane on the protrusion 12a comes in contact with the contact lever 86 during the upward rotation movement, thus the counting function of the developer cartridge is realized.

Embodiment 6

(53) Unless otherwise specified, the developer cartridge of the embodiment has the same structure with the developer cartridge of the Embodiment 3.

(54) The protrusions of the embodiment have the same structure with those of the Embodiment 5.

Embodiment 7

(55) Unless otherwise specified, the developer cartridge of the embodiment has the same structure with the developer cartridge of the Embodiment 2.

(56) As illustrated in FIG. 16, the hanging wall 23 and the cylinder 24 are arranged on the fixed member 20a which is fixed on the side wall 58 of the toner hopper 55; a first rotary member 14c and a second rotary member 14d are arranged on the rotary member 10a; the first rotary member 14c is provided with a concave hole 14b; a protruded post 14a is arranged on the second rotary member 14d and used with the concave hole 14b; the first rotary member 14c is arranged on an unthreaded portion 24b on the cylinder 24; the second rotary member 14d is also provided with the screwed hole 16 and the protrusions 15; and the screwed hole 16 is engaged with a threaded portion 24a on the cylinder 24.

(57) During the working process of the developer cartridge, a gear is arranged on the outer circumference of the first rotary member 14c and can receive power from the input gear 67 and keep rotating. In the rotation process of the first rotary member 14c, as the protruded post 14a is used with the concave hole 14b, the second rotary member 14d and the first rotary member 14c are driven to be in synchronous rotation; the second rotary member 14d is engaged with the threaded portion 24a through the screwed hole 16 and moves close to the first rotary member 14c, i.e. from the state as shown in FIG. 16 to the state as shown in FIG. 17.

(58) The first rotary member 14c of the embodiment is a hanging wall.

(59) It is obvious to those having ordinary skill in the art that the counting function of the developer cartridge can also be realized when the protrusions on the counting mechanism come in contact with the contact lever of the information detection mechanism when the rotary member moves away from the fixed member.

(60) Numerous characteristics and advantages have been set forth in the foregoing description, together with details of structure and function. While the invention has been disclosed in several forms, it will be apparent to those skilled in the art that many modifications, additions, and deletions, especially in matters of shape, size, and arrangement of parts, can be made therein without departing from the spirit and scope of the invention and its equivalents as set forth in the following claims. Therefore, other modifications or embodiments as may be suggested by the teachings herein are particularly reserved as they fall within the breadth and scope of the claims here appended.
