There is provided a magnetic recording/reproducing apparatus using a plastic chassis having side walls integrally formed with a bottom plate. A cassette holder holding the cassette case moves between a loaded position and an ejected position. A pair of pins are protrudingly provided on side surfaces of the cassette holder. One pin of the pair of pins is provided on a left side surface, and the other pin is provided on a right side surface. The plastic chassis has a bottom plate and left and right side walls formed perpendicularly on the left side and the right side of the bottom plate. The bottom plate and the left and right side walls are integrally formed with each other. A pair of slots are formed on the left and right side walls, one slot of the pair of slots being formed on the left side wall, the other slot being formed on the right side wall. The cassette holder is movably supported by the pins being inserted into the respective slots between the left side wall and the right side wall. A movement of the cassette holder is guided by the slots in extending directions of the slots.

There is provided a mounting construction of an elastic member of which one end is fixed to a mounting member fixed to and extending from a first member, the other end of the elastic member being engaged with a second member so that the second member is pressed against the first member, the elastic member having substantially a through hole extending in a pressing direction in which the second member is pressed. A first engaging portion, which is capable of being elastically deformed in a radially outward direction of the through hole, is formed on the one end of the elastic member. A first hook portion, being engaged with the first engaging portion, is formed on an end of the mounting member so that the first hook portion blocks a movement of the first engaging portion in a reverse direction of the pressing direction. The first hook portion may instead be elastically deformed. Additionally, the mounting member may comprise a plurality of circumferentially arranged protrusions capable of being elastically deformed, a center through hole being substantially formed in a center of the protrusions, at least one of the protrusions having a second hook portion protruding in a radially inward direction of the center through hole, a third member having a second engaging portion engaging with the second hook portion inserted into the center through hole so that the third member is mounted to the mounting member.

A tape loading mechanism includes: a chassis having a guide groove; a loading post assembly having a loading post and a loading post base, the loading post base being movably supported on the chassis and being movable along the guide groove, the loading post being supported on the loading post base and loading a tape onto a tape path of a rotating drum when the loading post base is moved to a loading end position; a projecting portion, projecting from an end of the loading post base in a direction of the movement of the loading post base, which is brought into contact with a drum base of the rotating drum when the loading post base is moved to the loading end position; and a stopper portion, provided within the drum base, for catching the projecting portion to stop the movement of the loading post base at the loading end position.

Tape loading mechanism with reduced height

A plastic chassis is provided in which a shaft is fixed to the chassis even if a snap fitting integrally formed with the chassis is broken. An arm member having a claw portion is formed around a through hole formed in the chassis. A protrusion having a top surface located a predetermined distance lower than a top surface of the arm member is formed around the through hole. When the shaft is inserted into the through hole, the claw portion engages with an annular groove formed near the end of the shaft so as to fix the shaft to the chassis. When the arm member is broken, a slit washer is engaged with the annular groove so as to fix the shaft to the chassis. The slit washer is disposed on the top surface of the protrusion.
