Title: Stapler and method for driving the same
Inventor: MATSUI TOMOKAZU
IPC: B25C5/15
Filed: 2012-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a stapler capable of reducing loads on a motor and coping with a variation in bound paper thickness by a simple structure.SOLUTION: A clinch completing position varies depending on a paper thickness difference. Thus, with a paper thickness time when clamping is fastest at a delay time (maximum bound number is 20) set as a reference, a motor is continuously driven in the same rotational direction by a difference between two which is a minimum bound number. That is, since the stroke difference of a driver unit caused by the paper thickness difference can be time-adjusted, even the bound paper having the paper thickness difference can be bound by the staples. Accordingly, since a driving means is continuously driven in the same rotational direction over the delay time, loads on the motor are reduced compared with a conventional art, and the stapler can cope with a variation in bound paper thickness by a simple structure. Furthermore, a service life of the motor becomes longer and failures are reduced compared with a conventional product.
