A staple sheet-detecting mechanism of an electric stapler having its detection accuracy improved and realizing miniaturization thereof is disclosed. <??>According to this staple sheet-detecting mechanism of the electric stapler, a passage 55 is provided for feeding a staple sheet 54 composed of straight forward staples arranged in parallel, and a forming plate 46 and driver 48 are arranged above an anvil 56A of the passage 55. A formed staple 54A is inserted into copy papers located under the staple 54A by moving the forming plate 46 and the driver 48 to a side of the staple 54A. <??>At that place above the anvil 56A where the forming plate 46 waits is provided a sensor (rocking member) 57 of which one end 57A contacts a tip edge of the staple sheet 54 in a feeding direction thereof, while the other end 57B turns on or off an interrupter (detecting element) 63. A rocking fulcrum 57C of the sensor 57 is provided biased to a side of the staple sheet 54 in the passage 55. The forming plate 46 and the driver 48 are provided with recessed portions 46A and 48A, respectively, for allowing the sensor 57 to rock. <IMAGE> |
