DEVICE FOR DISPENSING PAPER SECTIONS OF PREDETERMINED LENGTH
The invention relates to a device (10) for dispensing paper sections of predetermined length, with a device (26), which is operated by pulling on an end (74) of the paper web, and which separates the paper sections from the paper web (24) wound onto a paper roll (22) and provides easy manual access to the end (74) of the paper web that follows the separated paper section has been released. To allow a reliable and trouble-fee transporting, cutting, and dispensing of paper webs of high strength and elasticity, it is intended that the device (10) comprises a pressure spring (34) that bears upon a circumferential surface (36) of the paper roll (22), whereby a free end of the pressure spring (34) is oriented in a direction opposite to the direction of movement of the paper roll (22), whereby the pressure spring (34) is embodied rod-shaped and is connected pivotably to a portion (32) of the housing of the device (10), the pressure spring (34) is pivotable from a vertical operating position to a horizontal service position to release the paper roll (22), and the length of the pressure spring is such that in its pivoted state, one end of the pressure spring projects beyond the edge of the housing of the device (10).
Image forming apparatus provided with transmission mechanism for transmitting drive force to reconveying roller
An image forming apparatus includes a reconveying unit including a reconveying roller; and a second transmission mechanism. The second transmission mechanism transmits a drive force to the reconveying roller and includes an input gear; an output gear; an intermediate gear including first and second gears; and first and second swinging gears. The first toothless part of the first gear and the second toothless part of the second gear are provided at such a position that, when the intermediate gear is rotated by a drive force transmitted from the input gear through the second swinging gear while the second swinging gear meshes with the second toothed part of the second gear and the output gear meshes with the first toothed part of the first gear, the first toothless part reaches a position confronting the output gear and then the second toothless part reaches a position confronting the second swinging gear.
DRIVE TRANSMISSION APPARATUS AND IMAGE FORMING APPARATUS
The present disclosure provides a drive transmission apparatus capable of reducing vibration of rotating member. The apparatus includes a shaft, a pin, and a rotating member. The rotating member is engaged with the shaft by the pin and rotates with the shaft. A protruded portion is provided on one of an outer circumferential surface of the shaft and an inner circumferential surface of the rotating member. The rotating member is attached to the shaft with the protruded portion in pressure contact with another one of the outer circumferential surface of the shaft and the inner circumferential surface of the rotating member, so that swinging of the rotating member around the pin is restricted.
Sheet feeding apparatus and image forming apparatus
A sheet feeding apparatus includes a feed roller, a roller holder supporting the feed roller rotatably about a rotation axis, a frame supporting the roller holder pivotably about a first axis parallel to the rotation axis of the feed roller, a force-transmitting device configured to transmit, to the roller holder, a force with which to cause the roller holder to pivot in a direction where the feed roller is pressed against a tray, a force-applying member movable between a force applying position where the force-applying member contacts the force-transmitting device to apply the force thereto and a force-free position where the force-applying member is spaced apart from the force-transmitting device, and a cushioning member configured to, when the force-applying member is at an initial contact positon located between the force applying position and the force-free position, be sandwiched in contact between the force-transmitting device and the force-applying member.
Medium processing apparatus and image forming system incorporating same
A medium processing apparatus includes a conveyor, a tray, a binder, a mover, and a switcher. The switcher includes a first passage, a second passage, and a movable wall. The movable wall guides a guided portion of the binder to the second passage when the guided portion moving along the first passage from an end side to a center side contacts the movable wall; causes the guided portion to pass when the guided portion moving along the second passage from the end side to the center side contacts the movable wall; guides the guided portion to the first passage when the guided portion moving along the second passage from the center side to the end side contacts the movable wall; and causes the guided portion to pass when the guided portion moving along the first passage from the center side to the end side contacts the movable wall.
SHEET FEEDING APPARATUS AND IMAGE FORMING APPARATUS
A sheet feeding apparatus includes a sheet support portion configured to support a sheet, an ascending portion configured to cause the sheet support portion to ascend, a feeding portion configured to feed the sheet, a moving portion configured to support the feeding portion such that the feeding portion is movable between a separated position and a feeding position below the separated position, a holding portion configured to move between a holding position and an allowing position, a drive source, and a transmission unit including a first transmission portion configured to transmit the driving force to the ascending portion and a second transmission portion configured to transmit the driving force to the holding portion. The holding portion moves toward the allowing position in a case where the driving force is transmitted to the ascending portion and the holding portion respectively through the first transmission portion and the second transmission portion.
SUSPENDED SURFACE ASSEMBLY AND A METHOD FOR DEPLOYING SAME
A suspended surface assembly is provided having a trainable surface support element, a spindle component configured for training of the trainable surface support element therearound, a take-up action module configured to drivingly rotate the spindle component to thereby effect winding of the trainable surface support element onto the spindle component or to effect unwinding of the trainable surface support element from a partially or fully wound-up condition, and a lift complex for adjusting the vertical position of the trainable surface support element and the spindle component, the lift complex including a motive power element operable to both drivingly rotate the spindle component and to drivingly raise and lower the trainable surface support element and the spindle component. A method for operating the suspended surface assembly is also provided.
Recording medium conveyance apparatus and image forming apparatus
The apparatus includes a first clutch and a second clutch. The first clutch transmits rotation of the driving unit in a first rotation direction to the first feeding device without transmitting rotation of the driving unit in a second rotation direction that is reverse to the first rotation direction to the first feeding device. The second clutch transmits the rotation of the driving unit in the second rotation direction to the conveyance device and the double-side printing conveyance device and without transmitting the rotation of the driving unit in the first rotation direction to the conveyance device and the double-side printing conveyance device. The third transmission path is configured to transmit the rotation of the driving unit to a conveyance device. The fourth transmission path is configured to transmit the rotation of the driving unit to a double-side printing conveyance device.
DRIVE TRANSMISSION APPARATUS, SHEET FEEDING APPARATUS AND IMAGE FORMING APPARATUS
A drive transmission apparatus includes a first rotating unit rotated by driving force from a drive source and a second rotating unit rotated by the first rotating unit. The first and second rotating units includes first gear pair meshing at a first transmission ratio and second gear pair meshing at a second transmission ratio. A retention mechanism includes a protruded portion provided on the first rotating unit and a recessed portion provided on the second rotating unit, and is configured to retain a rotation angle of the second rotating unit by an engagement of the protruded portion and the recessed portion in a state where the first and second gear pairs are unmeshed.
Web Material Advancement Arrangement With An Entry Drive System In A Packaging Machine
