Abstract
Provided is a sheet stacking tray such that damage due to external force can be suppressed. The sheet stacking tray (30) is provided with a tray body (40), a first slide member (50), and a second slide member (60). When the first slide member and the second slide member are pulled out, the engagement between a first storage catch portion (44) of the tray body and a first latch portion (52) of the first slide member is released, and then the engagement between a second storage catch portion (54) of the first slide member and a second latch portion (62) of the second slide member is released.

A sheet placement tray comprising:
- a tray main body which has a sheet placement surface on which sheets are placed;
- a first slide member which is slidable with respect to the tray main body and which is arranged selectively either in a first stored position where the first slide member is stored in the tray main body or in a first pulled-out position where the first slide member is pulled out of the tray main body so as to extend the sheet placement surface;
- and
- a second slide member which is slidable with respect to the first slide member and which is arranged selectively either in a second stored position where the second slide member is stored in the first slide member or in a second pulled-out position where the second slide member is pulled out of the first slide member so as to extend the sheet placement surface, wherein
- the tray main body includes:
- a first storage engaged portion which is engaged with a first engaging portion of the first slide member in a state where the first slide member is stored in the first stored position;
- and
- a first pullout engaged portion which is engaged with the first engaging portion in a state where the first slide member is pulled out in the first pulled-out position,
- the first slide member includes:
- the first engaging portion;
- a second storage engaged portion which is engaged with a second engaging portion of the second slide member in a state where the second slide member is stored in the second stored position;
- and
- a second pullout engaged portion which is engaged with the second engaging portion in a state where the second slide member is pulled out in the second pulled-out position,
- the second slide member includes the second engaging portion,
- the first engaging portion is provided on a side surface of the first slide member and is an elastically deformable elastic piece having a first engaging protrusion which protrudes sideways,
- the first storage engaged portion and the first pullout engaged portion are protruding portions which protrude into the tray main body and which are engaged with the first engaging protrusion,
- the second engaging portion is provided on a side surface of the second slide member and is an elastically deformable elastic piece having a second engaging protrusion which protrudes sideways,
- the second storage engaged portion and the second pullout engaged portion are protruding portions which protrude into the first slide member and which are engaged with the second engaging protrusion,
- when the first and second slide members are pulled out from a state where the first and second slide members are stored respectively in the first and second stored positions, engagement of the first storage engaged portion with the first engaging portion is released, and thereafter engagement of the second storage engaged portion with the second engaging portion is released,
- when the first and second slide members are stored from a state where the first and second slide members are pulled out respectively in the first and second pulled-out positions, engagement of the second pullout engaged portion with the second engaging portion is released, and thereafter engagement of the first pullout engaged portion with the first engaging portion is released,
- the second storage engaged portion has a lamer protrusion amount than the first storage engaged portion, and
- the first pullout engaged portion has a larger protrusion amount than the second pullout engaged portion.
