A sheet discharge apparatus includes a pivot member pivoting in an up-down direction by being pressed by a sheet discharged from a sheet discharging portion, with the pivot member retained by being in contact with an uppermost sheet supported on the sheet supporting portion. A control unit changes a sheet interval between a preceding sheet and a succeeding sheet and executes a first discharge operation in which at least one sheet is discharged, and a second discharge operation in which sheets are discharged by the sheet discharging portion at a first sheet interval such that the pivot member does not contact with an uppermost sheet supported on the sheet supporting portion during the second discharge operation, and the control unit acquires a number of sheets to be discharged in the second discharge operation based on a detected position of the pivot member detected during the first discharge operation.

A drive transmission device includes a driving-side coupling, a driven-side coupling, and an intermediary transmission member provided therebetween. The driving-side coupling and the intermediary transmission member engage with each other so as to be movable in a first direction. The driven-side coupling and the intermediary transmission member engage with each other so as to be movable in a second direction crossing the first direction. The intermediary transmission member is held by a holding-side coupling which is one of the driving and the driven-side couplings or by a shaft member engaging with the holding-side coupling. Engagement of the intermediary transmission member with a non-holding-side coupling which is the other coupling permits a deviation angle about an axis extending in the first direction and a deviation angle about an axis extending in the second direction.

Provided is a one-way clutch in which a rotating direction of a first rotating member with respect to a second rotating member is switched. The first rotating member includes a recessed portion that receives a planetary gear and, in an outer circumferential portion thereof, an engaging portion that engages with the planetary gear, whereby relative rotation of the planetary gear and the first and second rotating members is switched to rotatable and unrotatable. When the first rotating member is relatively rotating with respect to the second rotating member, the planetary gear meshes with an internal gear of the second rotating member, and the position of the planetary gear is thereby restricted.

One-way clutch

A sheet conveyance apparatus includes a conveyance portion to convey a sheet in a sheet conveyance direction, and a moving member having a main body portion, a contact portion configured to come into contact with the sheet conveyed by the conveyance portion, and a shaft portion provided on the main body portion, with the moving member configured to be moved due to the contact portion contacting the sheet. A first support portion pivotably supports a first part of the shaft portion such that the moving member is configured to pivot around the shaft, and a second support portion pivotably and slidably supports a second part of the shaft portion such that the second part of the shaft portion swings around the first part. In addition, a biasing member biases the moving member, and a sensor transmits a signal according to a position of the moving member.
