【考案の詳細な説明】
本案は、例えば自動車などに組込んで使用するのに特に
適するカセットテーププレーヤに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cassette tape player that is particularly suitable for use in, for example, an automobile.
このようなカセットテーププレーヤは、その使用の簡便

に薄型を目的としたものとして例えば本出願人が先に出
願した特願昭５１−７９３６９号の発明がある。Many types of such cassette tape players are currently in use due to their ease of use, but for example, a patent application filed in 1973, which was filed by the applicant of the present invention, is designed to be particularly thin. There is an invention of No.-79369.

。That is, the invention is based on a motor 1 as shown in FIGS.
A pinch roller 4, a capstan 5,
A movable frame 8 is slidably provided with a transmission rod 15 for tilting the capstan 5, a reel bearing 6 for positioning the reel hub on the take-up side of the cassette, and a reel bearing 7 for positioning the reel hub on the output side of the cassette. It is a structure equipped with.

が送られ再生状態となる（第２図）。To play in such a structure, when the movable frame 8 with the tape cassette 13 attached is pushed inside the fixed frame 3, the transmission rod 15 comes into contact with the stopper piece 14, and as the movable frame 8 is pushed in, the movable frame 8 is pushed inward. The pinch roller 4 approaches the capstan 5 and pinches the magnetic tape, and the pulley 10 that drives the capstan 5 and the reel bearing 6 comes into pressure contact with the shaft of the motor 1, and the motor provided on the fixed frame 3 The drive switch 9 is turned on, the motor 1 rotates, the magnetic tape is fed, and a reproduction state is established (FIG. 2).

８から取外すことが可能となる。After using the tape cassette 13, when the movable frame 8 is pulled out, the pressure contact between the pulley 10 and the motor 1 is released, the driving force of the motor is no longer transmitted to the pulley 10, and the rotation of the pinch roller 5 and reel bearing 6 is stopped. It becomes possible to remove the tape cassette 13 from the movable frame 8.

ンチローラ４が圧接した状態になる。However, in the playback state where the tape cassette 13 is mounted on the movable frame 8 and has such a structure, the motor drive switch 9 comes into contact with the tape cassette 13 and the motor 1 rotates, causing the capstan 5 to rotate. It rotates, but
If the tape cassette 13 is not attached to the movable frame 8, and the movable frame 8 is pushed into the empty state to start playing, the switch 9 will not turn on and will rotate (the pinch roller will be attached to the capstan 5. 4 is in pressure contact.

が損なわれることがあった。If this state continues for a particularly long period of time, permanent deformation will occur in the elastic material such as rubber attached to the outer periphery of the pinch roller 4, and this will be pinched between the pinch roller 4 and the capstan 5. This causes variations in the magnetic tape transport speed, which may impair the normal functioning of the tape player.
本案は上述した従来の欠陥を解消することを目的とする

出してち・る（第４図）。The purpose of this invention is to eliminate the above-mentioned conventional defects, and the embodiment thereof will be explained below with reference to FIGS. A counterclockwise rotational force is applied by the spring 22 fixed to the movable frame 8 by the movable link, so that the link 20 is attached to the movable frame 8 when the cassette 13 is attached. 20' projects from the bottom of the movable frame 8 (Fig. 4).

スタン５がピンチローラに当接しない位置にある。23 is a protrusion formed on the bottom of the fixed frame 3, and when the movable frame 8 is pushed in from the state shown in FIG.
σ' abuts, the amount of sliding of the movable frame 8 is restricted, and the capstan 5 is in a position where it does not abut against the pinch roller.

生状態となる。With the above structure at °C, the cassette 13 is moved to the movable frame 8.
When the rotating link 20 is attached to the fixed frame 3, the rotating link 20 rotates clockwise against the spring 22.
When the movable frame 8 is pushed in, the other end 20'' of the rotary link 20 passes through the head of the protrusion 23, and the capstan 5 comes into pressure contact with the pinch roller 4 without restricting the amount of sliding of the movable frame 8. , enters the playback state.

るのが防止される。If the cassette 13 is installed and the movable frame 8 is in the L state,
When pushed in, the other end 20 of the rotating link 20 approaches the bottom of the fixed frame 3 and comes into contact with the protrusion 23, regulating the amount of pushing, and the capstan 5 moves towards the pinch roller 4. contact is prevented.

用である。Therefore, according to the present proposal, if the cassette is pushed in without being attached to the movable frame, the pushing amount will be regulated, the capstan 5 will not come into contact with the pinch roller 4, and the deformation of the pinch roller will be prevented. It is possible to prevent unevenness in the transport speed of the magnetic tape during the reproduction state, and is extremely useful in practice.
