- the punching device 60 is installed in a copying machine or the like, based on the detection of the movement to the opposite group by the movement range detection sensor 78, only the group on the side that is actually heavily used can be used. Control is performed. For example, when the power supply is restarted and the control is restarted after a system failure due to a power outage or the like, the control to move the cam plate 75 to the group used before the power outage is usually performed in the movement range.
- the presence of the sensor 78 is indispensable.
- the stopper 23 when the stopper 23 is provided and the sensor 78 is omitted, the movement to the opposite side of the cam plate 75 is not performed. It can be regulated by the stoppers 23. In that case, it is possible to reduce the product price by reducing the relatively expensive sensors 78. In other words, in addition to the cost of the movable range detection sensor 78 itself, the cost required for the control board (not shown) in the control means 80 can also be reduced. Downtime is expected, troubles caused by sensors and control are reduced, and maintenance can be reduced.
- an appropriate position in the slide groove of the synthetic resin slide guide 4 is closed with a synthetic resin material to form the stopper 23, so that the rack 83 moves leftward in FIG. 6 at a certain position.
- a member for example, a metal screw
- a member made of an appropriate material is placed at an appropriate position corresponding to the right end of the cam plate # 5 in the main body frame 70 in FIG.
- the punching device according to the present invention is useful as a device mounted on a main body of an image forming apparatus such as a copying machine, a printer, a facsimile, and a composite device thereof, or as a device mounted on a printing machine. It is suitable for devices that require simplification of the equipment by reducing the number of parts.
