DETAILED DESCRIPTION

[0014] Refer to FIG. 1 to FIG. 3. FIG. 1 is a 3D schematic diagram of a delivery mechanism of business machine according to a first embodiment of the invention. FIG. 2 is an explosion diagram of FIG. 1. FIG. 3 is a cross-sectional view of the delivery mechanism of business machine of FIG. 1 in conjunction with a flexible object.

[0015] The delivery mechanism of business machine 100 of the present embodiment is, for example, disposed within the business machine (not illustrated) for delivering a flexible object 20 (as indicated in FIG. 3). The business machine can be realized by such as a photocopier, a printer, a scanner, or a multi-function machine integrating the functions of photocopier, scanner and printer. The flexible object is a plate and can be bent and deformed according to the transmission path. When the flexible object is delivered by the delivery mechanism, the flexible object can be deformed and bent according to the transmission path. The flexible object can be realized by such as a plate, a film or a piece of paper.

[0016] The delivery mechanism of business machine 10 includes a carrier board 100, an assembly rack 200, a delivery wheel group 300, and two linkage assemblies 400.

[0017] The carrier board 100 has a carrying surface 110, a back surface 120 and a slot 130. The carrying surface 110 carries the flexible object 20. The back surface 120 is opposite to the carrying surface 110. The slot 130 passes through the carrying surface 110 and the back surface 120.

[0018] The assembly rack 200 is disposed above the carrier board 100. It should be noted: the assembly rack 200 can be disposed above the carrier board 100 through the carrier board 100 or other fixing casing of the business machine (not illustrated), but the invention is not limited thereto.

[0019] The delivery wheel group 300 includes two first rollers 310 and two second rollers 320. Both of the two first rollers 310 pass through the slot 130, and can be rotatably disposed on the carrier board 100. The second rollers 320 are disposed on the assembly rack 200. The second rollers 320 and lean on the first rollers 310. When the second rollers 320 are realized by passive rollers, the second rollers 320 can be driven by the first rollers 310 and have a rotation direction inverse to that of the first rollers 310. Furthermore, the second rollers 320 can be driven by a drive element (not illustrated), and have a rotation direction identical to that of the first rollers 310.

[0020] In the present embodiment, the quantity of the first rollers 310 and that of the second rollers 320 both are exemplified by two, but the invention is not limited thereto. In other embodiments, the quantity of the first roller 310 and that of the second roller 320 both are exemplified by one.

[0021] The delivery wheel group 300 is interposed between two linkage assemblies 400. Each linkage assembly 400 includes a rotation member 410 and a paper flattening member 420. The rotation member 410 is pivotally disposed on the assembly rack 200. Two opposite ends of the paper flattening member 420 are disposed at the rotation member 410 and the assembly rack 200, respectively. Specifically, the assembly rack 200 has a curved groove 210. One end of the paper flattening member 420 has a slider 421 slidably disposed in the curved groove 210. The other end of the paper flattening member 420 is pivotally disposed on the rotation member 410 by a pivot 500. Thus, when the rotation member 410 rotates with respect to the assembly rack 200, the rotation member 410 will displace the paper flattening member 420 horizontally along a curved path. Besides, the paper flattening member 420 has a paper flattening surface 422. During the displacement process of the paper flattening member 420, the paper flattening surface 422 face and is parallel to the carrying surface 110.

[0022] In the present embodiment, the pivot 500 is displaced along a curve L with respect to the assembly rack 200. Furthermore, since the distance between the slider 421 and the pivot 500 is different from the distance between the slider 421 and the carrier board 100, the curvature of the curve L is different from that of the curved groove 210, and the paper flattening member 420 is displaced horizontally along the curved path. However, the invention is not limited thereto. In other embodiments, if the distance between the slider 421 and the pivot 500 is the same as that between the slider 421 and the carrier board 100, the curve L will have the same curvature as that of the curved groove 210.

[0023] In the present embodiment, the quantity of the linkage assembly 400 is exemplified by two, but the invention is not limited thereto. In other embodiments, the quantity of the linkage assembly 400 can be singular.

[0024] Refer to FIG. 3 and FIG. 4. FIG. 4 is a cross-sectional view of the delivery mechanism of business machine of FIG. 1 in conjunction with another flexible object.

[0025] As indicated in FIG. 3, when the flexible object 20 passes between the first rollers 310 and the second rollers 320, the flexible object 20 will press the paper flattening member 420, and make the rotation member 410 rotate from the carrier board 100 (the direction of the arrow a), and the slider 421 will move away from the carrier board 100 along the curved groove 210 (the direction of the arrow b). Under the guidance of the rotation member 410 and the curved groove 210, the paper flattening member 420 will move away from the carrier board 100 (the direction of the arrow f) but will keep pressing the flexible object 20. It should be noted: the paper flattening member 422 almost presses the flexible object 20 by the entire surface, such that the flexible object 20 is flat when passing the first rollers 310 and the second rollers 320. That is, the paper flattening member 420 being displaced along the curved path helps to avoid the flexible object 20 being wrinkled or warped, and therefore reduce the probability of the delivery mechanism 10 having paper jam.

[0026] As indicated in FIG. 4, the delivery mechanism 20 is loaded with a flexible object 20 thinner than the flexible object 20. When the flexible object 20 passes between the first rollers 310 and the second rollers 320, the flexible object 20 still presses the paper flattening member 420. In comparison to the situation when the delivery mechanism 20 is loaded with the flexible object 20, the paper flattening member 420 is lifted to a lesser degree (farther away from the carrier board 100). That is, in comparison to the situation when the delivery mechanism 20 is loaded with the flexible object 20, the rotation member 410 will rotate towards the carrier board 100 (the direction of the arrow d), and the slider 421 will move towards the carrier board 100 along the curved groove 210 (the direction of the arrow e). Moreover, under the guidance of the rotation member 410 and the curved groove 210, the paper flattening member 420 will move towards the carrier board 100 (the direction of the arrow f), but will keep pressing the flexible object 20. It should be noted: the paper flattening surface 422 almost presses the flexible object 20 by the entire surface, such that the flexible object 20 is flat when passing the first rollers 310 and the second rollers 320. That is, the paper flattening member 420 being displaced along the curved path helps to avoid the flexible object 20 being wrinkled or warped, and therefore reduce the probability of the delivery mechanism 10 having paper jam.

[0027] As indicated in FIG. 3 and FIG. 4, no matter the delivery mechanism 10 is delivering the flexible object 20 having a larger thickness or the flexible object 20 having a smaller thickness, the paper flattening surface 422 presses the flexible object 20 or 20 almost by the entire surface to increase the paper flattening effect of the linkage assembly 400.

[0028] According to the delivery mechanism of business machine disclosed in above embodiments, the paper flattening member, under the guidance of the rotation member and the curved groove, will be displaced obliquely with respect to the carrier board. Therefore, regardless of the thickness of the flexible object, the paper flattening surface of the paper flattening member almost presses the flexible object by the entire surface to increase the paper flattening effect of the linkage assembly and avoid the problem of paper feed.

[0029] It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed embodiments. It is intended that the specification and examples be considered as exemplary only, with a true scope of the disclosure being indicated by the following claims and their equivalents.
