Claims

[Scope of utility model registration request]

By rotating a lever rotatably attached to the paper loading table in one direction, the paper feed separation claw is held in the non-operating position, and by rotating the lever in the other direction, the paper feed separation claw is placed in the operating position. a paper feed separation claw operating mechanism, a paper loading/unloading mechanism that switches the paper loading table between a fixed position and a released position relative to the machine base, and a paper feeding roller between an operating position and a non-operating position. and a paper feed roller fixing mechanism that holds the paper feed roller in the non-operating position, and the paper feed separation claw operating mechanism includes a wire whose end is fixed to the lever. The paper loading table engaging/disengaging mechanism is composed of a paper feeding separation claw movably inserted onto the wire and a claw lifting member fixed to the wire and lifting the paper feeding separation claw by movement of the wire. , the paper feed roller fixing mechanism is configured to support the paper feed roller, and is composed of a moving shaft movably attached to the paper loading table and a fitting hole provided on the machine base side into which the moving shaft fits. The lever includes a grooved disk connected to one end of the roller arm, and a locking claw attached to the machine base side that locks into the groove of the grooved disk, and the lever further includes:
When the paper feed separating claw is held in a non-operating position, the grooved disk is rotated to move the paper feeding roller to a non-operating position and the locking claw is locked to the grooved disk. When the operating member of the roller position switching mechanism and the paper feed separation claw are held in the operating position, the moving shaft is moved to fit into the fitting hole, and the paper feed separation claw is held in the non-operation position. A paper feeding device for a copying machine or the like, which is equipped with an operating member of a paper table engagement/disengagement mechanism that moves the moving shaft in the opposite direction to disengage the paper table from the fitting hole.
