The magnetic head (13) is placed and fixed so as to oppose thereto, the pinch roller (14) is rotatably supported, and the tape guides (15a) (15b) are fixed thereto. The head base (11) has a magnetic head (13), a pinch roller (14), and tape guides (15a) and (15b) arranged on the head base (11) of a tape cassette C held by a cassette holder (3). It is movably provided between a position to be inserted into the front opening (tape exposed portion) and a position to be detached from the tape cassette C.

Further, a head base moving means (16) for moving the head base (11) is provided at the back of the cassette holder (3).

That is, a shaft pin (17) is erected on one end side of the inner part of the cassette holder (3), and a torsion coil spring-like operation spring (18) as an elastic operation member is provided on the shaft pin (17) of the coil part. It is rotatably fitted in (18a). The arm portion (18b) on one end side of the operating spring (18) is horizontally L
It is bent in the shape of a letter and protrudes forward, that is, in the direction opposite to the insertion direction of the tape cassette, and its tip is bent in the shape of a letter in the direction of the switch, while the other end side arm (18c)
Is abuttingly engaged with an engaging pin (19) provided upright on the free end portion of the head base (11), and this operating spring (18) is pressed by the tape cassette C and rotated as described later. By doing so, the head base (11) is moved.

On the other hand, the cassette player main body (2) side is provided with a cassette moving means (20) for moving the tape cassette C and operating the head base moving means (16) during the mounting operation of the tape cassette C.

In this example, the cassette moving means (20) is provided in the player section (4), that is, the tape cassette is mounted on the vertical surface section of the player section (4) facing the hinge section of the cassette holder (3). In this state, a defining convex portion (21) for defining and supporting the rear end face is formed, and an inclined edge (21a) inclined downward toward the hinge portion side of the cassette holder (3) is formed on the upper portion of the defining convex portion (21).
