Push feed arm for post processing device
First Claim
1. A sheet post-process apparatus, the apparatus comprising:
- a waiting tray which temporarily retains a transported sheet and releases the sheet;
a processing tray which bundles the sheets dropped from the waiting tray to carry out predetermined processing and ejects the bundled sheets; and
a storage tray which holds the bundle of sheets processed and ejected on the processing tray,wherein the processing tray comprises;
a transport belt which transports the bundle of sheets; and
a push feed arm mounted to be projected onto a surface on a sheet transport side of the transport belt, the push feed arm retaining a sheet distal end of the bundle of sheets so that the sheet distal end can be pushed and fed;
wherein the transport belt forms a through hole through which the push feed arm penetrates, andthe push feed arm comprises;
a push feed face which pushes and feeds the sheet distal end;
a penetrating projection portion which reaches a transport belt lower face from the push feed face through the through hole; and
a hook shaped engagingly lock portion, formed integrally with the penetrating projection portion, engagingly locked on the transport belt lower face and being bent in the transport belt traveling direction, andwherein a face of the hook shaped engagingly lock portion on a side which comes into contact with the belt lower face is inclined in a downward direction at an angle of 10 degrees to 30 degrees while a longitudinal direction of the transport belt is defined as a reference.
