Abstract

A clipping device is provided which comprises: a cartridge containing a belt of plate-shaped clips arranged like a belt; a pair of clamps for holding and bending the upper and lower ends of a clip occupying the front of the clip-arranged belt and thereby separating the front clip from the clip-arranged belt and fastening the end of a bundle of sheets with the separated front clip; a slider that reciprocates between the cartridge and the pair of clamps so that the clip-arranged belt is fed from the cartridge to the pair of clamps; a control unit that controls and drives the pair of clamps and the slider; and a clip-setting-detecting unit that detects whether the separated clip is held by the pair of clamps or not. The control unit has a clip-setting-detecting step in which the slider is caused to perform an operation of feeding the clip-arranged belt a predetermined number of times in a state in which the pair of clamps are opened and are ready to receive the clamp-arranged belt and, if the clamp-arranged belt is not detected by the clip-setting-detecting unit during the predetermined number of times, the pair of clamps and the slider are stopped from being driven.

A clipping device comprising:

a cartridge containing a belt of plate-shaped clips arranged like a belt, said cartridge being provided with an outlet for the clips;
a pair of clamps for holding and bending both ends of a clip occupying a front position of the belt of plate-shaped clips and thereby separating the front clip from the belt of plate-shaped clips and fastening a bundle of sheets with the separated front clip;
a slider that reciprocates between said cartridge and said pair of clamps and feeds the belt of plate-shaped clips from said cartridge to said pair of clamps;
control means for controlling and driving said pair of clamps and said slider;
and
clip-setting-detecting means for detecting whether one of the plate-shaped clips is held by said pair of clamps or not;
wherein said control means has a detecting step in which said slider is caused to perform an operation of feeding the belt of plate-shaped clips per a clip a predetermined number of times in a state in which said pair of clamps are opened and are ready to receive the belt of plate-shaped clips when no clip is set between said pair of clamps and, if the belt of plate-shaped clips is not detected by said clip-setting-detecting means during the predetermined number of times, said pair of clamps and said slider are stopped from being driven.
