摘要： A driving force transmission device includes a drive gear, a driven gear, which includes a gear portion and a partially toothless gear portion, rotates by the gear portion meshing with the drive gear, stops rotating in response to the partially toothless gear portion facing the drive gear, a first cam member and a second cam member which operate in conjunction with the driven gear, a first elastic member for urging the first cam member, a follower member to which urging force is applied by a second elastic member and which is moved by the second cam member, and a contact portion for coming into contact with the first cam member by urging force of the first elastic member. The first cam member includes a home cam surface for coming into contact with the contact portion so that rotation of the driven gear is limited.

摘要： A sheet conveyance apparatus includes a guide member, a holding member, and urging members. The guide member can move between a first position to guide a conveyed sheet toward a first conveyance path and a second position to guide the conveyed sheet toward a second conveyance path. A first urging member applying applies an urging force to the holding member so that the guide member is held at the first position. The second urging member applies, to the guide member, an urging force to move the guide member from the first to the second position. The holding member is movable between a hold position at which the guide member is held and a release position in which the holding member releases the guide member. When the holding member is at the release position, the guide member is held at the second position by the second urging member urging force.

摘要： A sheet feeder includes a sheet platen, a pickup roller, a feeding roller, a regulating portion, a driving mechanism, a feeding control unit, a sheet sensor, and a determination processing unit. The feeding control unit executes a feeding operation by rotationally driving the pickup roller and the feeding roller in a state where the regulating portion is located at a retreating position. The sheet sensor is located at a downstream side in the feeding direction of the feeding roller. The determination processing unit determines whether the sheet feeding has succeeded or not based on a signal from the sheet sensor. After a start of the feeding operation, when the determination processing unit determines that the sheet feeding has failed, the feeding control unit once moves the regulating portion located at the retreating position to the abutting position and then executes the feeding operation again.

摘要： A drive transmission device includes a first gear, a second gear, a switch arm, a third gear, a first sector gear including a first teeth portion and rotatable about a second axis in a predetermined direction, a second sector gear including a second teeth portion and engaging the first sector gear movably with play in the predetermined direction, a lever, a solenoid, and a first urging member. The switch arm has a cam contact surface, and the second sector gear includes a cam configured to contact the cam contact surface. When the first sector gear rotates in the predetermined direction for a predetermined amount from a state where the third gear engages the first gear and where the first teeth portion and the second teeth portion disengage from the second gear, the first teeth portion engages the second gear, and the second teeth portion disengages from the second gear.

摘要： A feeding device includes a stacking member, a raising device, a feeding member, an interlocking device including a sheet contact portion, a switching device, a holding member, and a movement device. The feeding member is movable between contact and retracting positions, and rotates in contact with a sheet stacked on the stacking member in a state of being located at the contact position. The sheet contact portion contacts the stacked sheet, and moves by being pressed against the stacked sheet where the raising device raises the stacking member. The switching device switches the raising device between a permitted state and a regulated state. The movement device moves the feeding member to the retracting position above the contact position by moving the holding member. The raising device does not change from the regulated state to the permitted state when the movement device moves the feeding member to the retracting position.

摘要： 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.

摘要： A drive transmission apparatus in which, when immobilization of a preceding gear (21) by a solenoid (22) is canceled, an urging portion urges the preceding gear (21) to rotate in a direction in which the preceding gear (21) meshes with an input gear (24) which rotates at a constant velocity. An interlocking portion causes an output gear (20) to mesh with the input gear (24) in association with the rotation of the preceding gear (21), to rotate the output gear (20) at a low velocity, and to rotate the output gear (20) at a high velocity when the output gear (20) rotates by a predetermined amount.

摘要： Torque is applied to a separation roller of an image processing apparatus when a leading edge of the sheet in a transport direction reaches a first transport roller and when the leading edge of the sheet in the transport direction reaches a transport unit. Torque to the separation roller is cut off after the leading edge of the sheet has reached the transport unit but before the leading edge of the sheet reaches the image processing unit.

摘要： A drive switching mechanism includes a transmission gear and a planetary gear configured to transmit a drive from an input gear to an output gear. The drive switching mechanism further includes a swinging member configured to hold the planetary gear such that the planetary gear can swing around the input gear, a retaining unit configured to retain the swinging member in a swing enabled or disabled state, and a releasing unit configured to disengage the planetary gear from the output gear and cause them to be spaced apart. The output gear includes a toothless part that does not engage with a gear section engaging with the transmission gear.
