るなどの欠陥があった。Problems to be Solved by the Invention However, according to the above-mentioned conventional tape player, the cassette may be accidentally inserted into the tape player installed in a car due to an abnormal situation, such as when a foreign object is inserted into the cassette slot. When the tape player is operated by inserting the cassette into the insertion slot, the foreign object prevents the cassette holder from moving downward sufficiently, and the cassette holder does not reach the correct play position. performs all mechanical operations independently,
As a result, there is a risk that excessive mechanical force will be applied and cause mechanical damage, or that the drive motor will overheat and cause electrical damage, making it impossible to remove the cassette. There were defects such as

Then, through the engagement between the protrusion and the engagement step, the displacement member Q
As the spring moves in a clockwise direction, the protrusion disengages from the engagement step and moves within the guide fkm, so the second □
As is clear from Figure 2, the rearward movement of the eject member tt'n was carried out without any problem, and the same operation as the eject operation was performed after that, and the eject member surface and the d'1-included structure were removed. is written to the non-playing state, and the cassette P is ejected, and in this case as well, the above-described defect t-S of the conventional one can be erased.

The hole ah that engages with the claw piece of the sliding part provided in the sliding part is actively formed to be large, and the claw piece a is pressed against the front edge of the hole (13) 1L of the spring @. Therefore, the cassette P is inserted into the cassette holder (3), and then the cassette P is forcibly drawn into the retracting mechanism, and in the middle of this, for example, as mentioned above, part of the label gets caught and the cassette P is pulled out. If retraction is prevented, the hole ah and the claw piece (2
Since there is a space between the lever (13) and the lever (13) in the stopped state, the claw piece of the Nwb part +211 resists the spring and moves backward from the front edge of the hole (13) a. Move backwards as far as the edge (Figure 23).

As a result, for example, the lower surface of the cassette P comes into contact with the tip of the reel shaft disposed on the frame (11), and the cassette holder (3) is prevented from descending, thereby locking the ejecting member αB. Since it does not work, the same effect as when ejecting is performed, and the ejecting member (1η and sliding piece c!
The retraction mechanism including 1) is restored and the cassette P is automatically ejected, eliminating the risk of damaging the drive motor (b) and other mechanisms.
