<p>A detecting mechanism of an electric stapler is provided for detecting an abnormal state in which sheets (2) of paper are not normally fastened together with staples (3). The detecting mechanism comprises a stapling base (1) on which sheets (2) of paper are laid and which has a space for receiving the ends (3b) of legs (3a) of a staple (3) which have been driven through the sheets, a pair of clinchers (6A, 6B) rotatably mounted under the receiving space, and a driver (8) for rotating each of the clinchers (6A, 6B) in a predetermined direction so as to press and clinch the ends (3b) of the legs (3a). The clinchers (6A, 6B) are each rotated in a direction opposite to the predetermined direction when the legs (3a) of the staple (3) have been driven through the sheets (2). The detecting mechanism is provided with a photosensor (12) for detecting the rotation of the clinchers (6A, 6B) when the clinchers (6A, 6B) are each rotated in the opposite direction. <IMAGE></p> |
