Abstract
A punching mechanism has a plurality of predetermined standby positions where the punching mechanism is previously moved by move means and stands by based on size information in the width direction of a sheet material and punching execution information as to whether or not the sheet material is to be punched. The standby position corresponding to a sheet material of the maximum width that can be punched by the punching mechanism and the standby position applied when punching is not executed are set to substantially the same position.
Claims7
A punching system for punching holes in a sheet material being transported, said punching system comprising:
- a sheet transport means for transporting the sheet material;
- a driver for driving said sheet transport means;
- a punching mechanism including a plurality of punches disposed on a transport passage of the sheet material in a predetermined spacing in a direction orthogonal to a transport direction of the sheet material and operative to punch a plurality of holes in the sheet material in the predetermined spacing along a width direction of the sheet material;
- and
- first sensing means disposed on the transport passage of the sheet material positioned in the width direction between two adjacent punches for sensing either a beginning or an end margin in the transport direction of the sheet material transported to the punching mechanism,
- wherein the punching mechanism is operated based on sensing information output from the first sensing means in a sheet material stop state where said driver stops the driving of said sheet transport means a given period of time after said first sensing means detects either the beginning or the end margin in the transport direction of the sheet material to stop the sheet material once, thereby punching a plurality of holes at a predetermined distance from either of a selected beginning or end margin in the transport direction of the sheet material irrespective of a thickness of the sheet material.
