PURPOSE:To simplify the structure of an interlocking mechanism for easy assembly by providing an interlocking part to a drive member or an intermediate member to interlock a part of the other member and to move back the drive member and hooking/releasing the interlocking part in accordance with the reciprocating motions of the drive member. CONSTITUTION:A loading/unloading mechanism functions to load and unload a member to be driven (oscillating angle 62 of oscillating member 64) to and from a moving drive member (rack member 48) with the prescribed timing and extracts the slight movements of the angle 62 against a large shift stroke of the member 48. The loading/unloading mechanism is provided with an intermediate member 76, an interlocking part 48k formed to one (member 48) of both members 48 and 47 and interlocks a pin 76b of the other member and a hooking/ releasing means (cam hole 40f of the rail 40) which hooks and unhooks the part 48k in response to the reciprocating motions of the member 48. Thus only the member 76 can constitute substantially the loading/unloading mechanism and therefore an interlocking mechanism is simplified and can be assembled easily.
