2. Description of the Related Art In recent years, audio equipment has tended to be digital audio, and with the development of technology, a tape recorder with high fidelity by digital recording and digital reproduction has been developed, and R-DAT by a rotary head and S-by a fixed head. DA
Two schemes of T have been proposed. Especially S-DAT
Because of the fixed head, the structure of the head and tape cassette is similar to the analog tape recorder that is widely used at the present time, so that one tape recorder can record and reproduce both analog and digital signals. Is expected to be commercialized.

Currently proposed tape recorders of a system capable of recording and reproducing both analog and digital signals are conventional tapes having a thick portion at a front opening for inserting a magnetic head, a pinch roller and the like. A cassette (an analog compact cassette, hereinafter abbreviated as ACC) and a front opening for inserting a magnetic head, a pinch roller, etc. are covered when not in use and slid in the running direction of the magnetic tape or in the opposite direction when in use. Both a tape cassette with a shutter (digital compact cassette, hereinafter abbreviated as DCC) for opening the front opening can be mounted on the same tape recorder. In this way, even tape cassettes with different shapes are recorded or played back by a single tape recorder. Therefore, tape cassettes with different shapes may be used for tape recorders such as vehicle-mounted tape recorders that have a tape cassette loading mechanism. It became necessary to attach and detach those tape cassettes to and from the tape recorder by the same loading mechanism.

A conventional tape recorder of this type for ACC will be described below. The structure of a conventional tape recorder for ACC is shown in FIGS. 6 and 7. That is, FIG. 6 is a plan view of the internal mechanism of a conventional ACC tape recorder having a loading mechanism, and FIG. 7 is a side view of the loading portion of the tape recorder. 6 and 7
1 is ACC, 2 is a reel shaft insertion hole, 3 is a tape cassette holder for holding a tape cassette, 4 is A

Reference numeral 5 is an arm member for moving the holding member 4, 6 is a rotating shaft of the arm member 5, 7 is a protrusion which is connected to the holding member 4 and fits into the reel shaft insertion hole 2, and 8 is a main component. Mechanical board for mounting, 9 is holder support member,
10 is a hinge.

Next, the operation will be described. As shown in FIG. 6, the projection 7 connected to the holding member 4 has the reel shaft insertion hole 2
When the ACC1 is manually inserted into the holder until the ACC1 is fitted, the holding member 4 moves and the ACC1 is pulled into the tape cassette holder 3 as the arm member 5 rotates about the rotation shaft 6. When the ACC1 reaches the deepest part of the tape cassette holder 3, the holder supporting member 9 rotates downward about the hinge 10 as a center of rotation, and the tape cassette holder 3 descends, as shown by a chain double-dashed line in FIG. A
CC1 reaches the final loading position indicated by the chain double-dashed line, and loading of the tape cassette is completed.

[0006]

However, in the conventional tape recorder as described above, there is no structure for pressing and urging the tape cassette toward the magnetic head when the loading is completed, so there is no problem in using the ACC. In particular, when using a DCC that has many recording tracks and needs to perform recording and reproduction at minute dimension intervals, there arises a problem that the recording and reproduction cannot be performed correctly.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned conventional problems, and during the loading of the tape cassette, the loading is smoothly performed without hindering the loading, and the magnetic head of the tape cassette in the loading completed state.
