Abstract

A monitoring device is described for use with a stapler apparatus arranged to move into and out of an operating position to detect the presence or absence of staples at a predetermined point during staple movement in the magazine 97 therefor. In one embodiment, the monitoring which is mounted in a fixed position is accom-plished at the inoperative position of the apparatus by means of fiber bundles 113, 114 which conveys light through an opening 110 in the magazine and directed upon the staples and conveys reflected light from the staples S to a light sensitive element 116. In another embodiment, the monitoring is accomplished during any positions which the apparatus may assume by means of a light emitter and a light detector arranged on opposite sides of the magazine to sense the transmission of light through aligned openings in the magazine as an indication of a low staple supply condition in the magazine.
