Abstract:
A sheet punch device, comprising:a first punch member including a rotatable punch and die pair configured to punch a hole in a sheet;a first driving member configured to drive and rotate the first punch member to punch a hole in a conveyed sheet;a moving/driving device configured to move the first punch member in a direction perpendicular to a sheet conveying direction;a second punch member including a rotatable punch and die pair configured to punch a hole in a sheet, and being positioned a predetermined distance from the first punch member in a direction perpendicular to the sheet conveying direction;a second driving member configured to drive and rotate the second punch member to punch a hole in the conveyed sheet;a first punch hole information setting device configured to set punch hole information for punching holes in the conveved sheet at plural places aligned in the sheet conveying direction; anda second punch hole information setting device configured to set punch hole information for punching holes in the conveyed sheet at plural places aligned in a direction perpendicular to the sheet conveying direction,wherein the sheet punch device punches holes in the conveyed sheet based on signals from one of the first punch hole information setting device and the second punch hole information setting device;wherein the moving/driving device moves the first punch member to a predetermined distance from an edge of the conveyed sheet so the first punch member punches holes in the conveyed sheet at plural places aligned in the sheet conveying direction when a request is made to punch holes in the conveyed sheet at plural places aligned in the sheet conveying direction via the first punch hole information setting device, andwherein the moving/driving device moves the first punch member to a predetermined distance from the second punch member so the first punch member operates in unison with the second punch member to simultaneously punch holes in the sheet at least at two places in the direction perpendicular to the sheet conveying direction when a request is made to punch holes in the conveyed sheet at plural places aligned in the direction perpendicular to the sheet conveying direction via the second punch hole information setting device.
