IPC: B41L13/04
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of erroneous operation caused by shift of timing for fixing/removing a plate cylinder unit to/from the stencil printer body by releasing the holding state through operation of a holding means and then drawing the plate cylinder unit from the stencil printer body. SOLUTION: When a plate cylinder unit is drawn out from the stencil printer body, holding state of the plate cylinder unit is regulated until electric connectors 77, 79 are separated to release conducting state of an ink sensor perfectly and thereby the plate cylinder unit is not moved. When the holding state of the plate cylinder unit is released and drawing operation is started, the electric connectors 77, 79 are separated to release electrically connecting state thus preventing occurrence of erroneous operation of the ink sensor, or the like. Consequently, excessive ink supply due to erroneous operation of the ink sensor, leakage of ink being supplied excessively or excessive ink supply at the time of next print operation can previously be prevented.
