Print sheet transfer device

Abstract

A print sheet transfer device has upstream rollers, downstream rollers, and a pair of first and second guide plates movable between a guide position and a release position for a print sheet. When the guide plate is moved from the guide position to the release position, the upstream side of the print sheet held with the upstream rollers is fed in a transfer direction in accordance with the movement. When the downstream side of the print sheet is held with or thrusted against the downstream rollers, a sag is formed in the print sheet between the upstream rollers and the downstream rollers. It is possible to easily perform an operation to remove the print sheet.

1 . A print sheet transfer device comprising:
 an upstream roller that conveys a print sheet;   a downstream roller that conveys the print sheet;   a guide plate, provided between the upstream roller and the downstream roller, that is movable between a guide position to guide the print sheet and a release position to release the print sheet;   a first interlocking mechanism that rotates at least one of the upstream roller and the downstream roller in accordance with an operation to move the guide plate from the guide position to the release position, to form a sag in the print sheet between the upstream roller and the downstream roller, and when the print sheet is transferred, does not transmit rotation of the upstream roller and the downstream roller to the guide plate.   
     
     
         2 . The print sheet transfer device according to  claim 1 , wherein the first interlocking mechanism rotates the upstream roller in a print sheet transfer direction in accordance with the operation to move the guide plate from the guide position to the release position, so as to feed the print sheet in contact with the upstream roller in the transfer direction, to form the sag in the print sheet. 
     
     
         3 . The print sheet transfer device according to  claim 1 , wherein the first interlocking mechanism rotates the downstream roller in an opposite direction to a print sheet transfer direction in accordance with the operation to move the guide plate from the guide position to the release position, so as to feed the print sheet in contact with the downstream roller in the opposite direction to the transfer direction, to form the sag in the print sheet. 
     
     
         4 . The print sheet transfer device according to  claim 2 , further comprising a second interlocking mechanism that rotates the downstream roller or the upstream roller in an opposite direction to a rotational direction of the upstream roller or the downstream roller in accordance with a rotation of the upstream roller or the downstream roller interlocked with the operation to move the guide plate from the guide position to the release position, so as to form the sag in the print sheet, and when the print sheet is transferred, does not transmit the rotation of the upstream roller or the downstream roller to the downstream roller or the upstream roller.
