Abstract
A sheet conveyance device includes a first conveyance member, and a drive transmission mechanism. The first conveyance member is configured to convey a sheet toward a second conveyance member. The drive transmission mechanism is configured to transmit a driving force of a driving source to the first conveyance member. The drive transmission mechanism includes a first drive transmitter and a second drive transmitter disposed coaxially with the first drive transmitter. The driving force is transmitted from the first drive transmitter to the second drive transmitter. The second drive transmitter is rotatable relative to the first drive transmitter within at least a predetermined angular range.
Claims8
A sheet conveyance device comprising:
- a first conveyor to convey a sheet toward a second conveyor;
- and
- a drive transmission mechanism to transmit a driving force of a driving source to the first conveyor,
- wherein the drive transmission mechanism includes:
- a first drive transmitter;
- and
- a second drive transmitter disposed coaxially with the first drive transmitter and to which the driving force is transmitted from the first drive transmitter, the second drive transmitter being rotatable relative to the first drive transmitter within at least a predetermined angular range,
- wherein each of the first drive transmitter and the second drive transmitter includes a claw,
- wherein the driving force is to be transmitted from the claw of the first drive transmitter to the claw of the second drive transmitter, and
- wherein at least one of the claw of the first drive transmitter and the claw of the second drive transmitter includes a recess.
A sheet conveyance device comprising:
- a first conveyor to convey a sheet toward a second conveyor;
- and
- a drive transmission mechanism to transmit a driving force of a driving source to the first conveyor,
- wherein the drive transmission mechanism includes:
- a first drive transmitter;
- and
- a second drive transmitter disposed coaxially with the first drive transmitter and to which the driving force is transmitted from the first drive transmitter, the second drive transmitter being rotatable relative to the first drive transmitter within at least a predetermined angular range,
- the sheet conveyance device further comprising:
- an intermediate member between the first drive transmitter and the second drive transmitter and movable in a thrust direction,
- wherein the second drive transmitter is to receive the driving force from the first drive transmitter via the intermediate member, and
- wherein the intermediate member is to move toward the first drive transmitter to interrupt a drive transmission between the second drive transmitter and the first drive transmitter,
- wherein the intermediate member is rotatable relative to the first drive transmitter and the second drive transmitter,
- wherein the intermediate member includes:
- a first claw extending in the thrust direction to receive the driving force from the claw of the first drive transmitter;
- and
- a second claw extending in the thrust direction to transmit the driving force to a claw of the second drive transmitter into a claw of the first drive transmitter,
- wherein the claw of the first drive transmitter is coupled with an inclined portion that contacts the first claw from the thrust direction and having a gradient in the thrust direction, and
- wherein the claw of the second drive transmitter is coupled with an inclined portion that contacts the second claw from the thrust direction and having a gradient in the thrust direction.
