Title: Paper sheet feeding device
Inventor: UEHARA KAZUMI
IPC: B41J13/02
Filed: 1989-02-16
Abstract: PURPOSE:To attain cost down and miniaturization due to simplification of the construction by providing a pressing mechanism having a pressing member energizated to contact with the position in rear of the position on which a paper sheet feeding roller contacts to an overlapped feed preventing member, and a guide mechanism capable of setting the extreme end of a paper sheet between the pressing member and the paper sheet feeding roller. CONSTITUTION:Pressing pieces (pressing member 4) of a pressing plate piece 20 constituting a pressing mechanism 5 are contacted to a paper sheet feeding roller 2. The contacted position is in rear of the position contacted with an overlapped feed preventing roller 3. Paper sheets P are guided with a tray part 23 and a guide plate part 24 of a guide mechanism 6, and the extreme ends are set between the paper sheet feeding roller 2 and the pressing pieces 20a, 20b. In this case, as the paper sheets P are pressedly contacted to the paper sheet feeding roller 2 by pressing action of the pressing member 4, the uppermost paper sheet is fed by rotation of the roller 2. At this time, as the overlapped feed preventing roller 3 does not rotate in the feeding direction of the paper sheet P, the uppermost paper sheet is only fed. Thus, the paper sheet feeding roller 2 serves both as a paper feed function and an overlapped feed preventing function, and parts material such as motor, gear mechanism are reduced in half.
