Claims

[Scope of Claim for Utility Model Registration] A cassette holder is provided in which a cassette can be inserted and is vertically movably mounted within a housing, and the housing is coupled to the cassette holder and is configured to guide the vertical movement of the cassette holder. An arm is provided that protrudes from a guide pin that is inserted through a guide slot formed in the body and is rotatably attached to the housing, and the housing moves in accordance with the vertical movement of the guide pin of the arm. A slide plate movable in the front and back direction is attached to the housing, and a drive gear is integrally attached to which a drive motor is connected and a rotating plate for retracting the cassette into the cassette holder. a drive plate is provided in the housing near the slide plate, internal teeth are formed on the inner edge of the outer periphery of the drive plate, and an intermediate gear is interposed between the internal teeth and the drive gear in a meshing state, Furthermore, a cam drive connecting plate connected to the support shaft of the intermediate gear is attached to the slide plate, and
The cam drive connecting plate is formed with a regular circular arc groove along the rotation locus of the drive plate and a reverse circular groove communicating with the regular circular groove, and a drive pin that slides in both circular arc grooves. By providing it on the drive plate, the cam drive pin is prevented from moving during the period when the cam drive pin slides along the regular circular arc groove of the cam drive connecting plate, and the cam drive pin is provided in the reverse circular arc groove. A setting mechanism for a cassette holder in a magnetic recording/reproducing apparatus, characterized in that the cassette holder is moved up and down by sliding the cam drive plate and the slide plate while the cassette holder is moving along an arcuate groove.
