APPARATUS FOR SMOOTHLY CONNECTING DRIVING FORCE CONVEYING JOINT WITH DRIVING FORCE RECEIVING JOINT

摘要

A rotating apparatus for rotating, by transferring a driving force generated by a motor disposed in a body to a rotation member detachable from the body. A driving shaft disposed in the body transfers the driving force by rotating itself in a prescribed direction. A driving force receiving device has a receiving joint and is in the rotation member to receive the driving force. A transferring device engages the driving shaft and transfers the driving force to the rotation member. The transferring device includes transferring joint for engaging with the receiving joint. A moving member moves the transferring device back and forth along the driving shaft so as to engage and disengage the transmitting joint respectively with the receiving joint when the receiving device contacts the transferring device. A guiding member is provided at least one of the driving shaft and the transferring device. A camshaft is provided on the driving shaft and the transferring device and fits into the guiding member. The camshaft comes in close proximity with contacts one end of the guiding member when the receiving joint and transferring joint engage. The cam shaft comes in close proximity with another end of the guiding member when transferring joint separates receiving joint at its initial position. In addition, the camshaft in relation to the guiding member is tightly fitted near one end thereof and loosely fitted near the other end thereof.
