Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a cassette tape player, and in particular, a cassette tape player that plays a cassette tape by inserting it into a cassette holder, and also plays a cassette tape by inserting the cassette tape into a cassette holder. This relates to a device that allows a cassette tape to be taken out by projecting it forward from inside a holder.

[Technical background of the invention and its problems]

For example, in a cassette tape player for a car stereo, when a cassette tape is inserted into a cassette holder, the cassette tape is engaged with a reel stand, etc., and the cassette tape can be played.
When the eject button or the like is operated in this state, after the cassette tape is separated from the reel stand etc., the cassette tape is projected forward from inside the cassette holder by a pushing body such as an eject arm that is biased by a spring or the like. This allows the cassette tape to be taken out.

In this case, the cassette tape pushed out by a pusher such as an eject arm remains unstablely supported by the cassette holder, with only its rear end remaining inside the cassette holder.

Therefore, when the car is running, the cassette tape may fall off from the cassette holder due to the vibrations of the car body, and furthermore, when the cassette tape is ejected, the cassette tape may fly out of the cassette holder. There is a high possibility that the tape will become soiled or damaged, and furthermore, if the driver is distracted from disposing of the cassette tape, safe driving will be hindered.

[Purpose of invention]

The present invention has been devised in view of the above-mentioned problems, and is intended to prevent the cassette tape projected forward from the cassette holder by the eject operation from falling off the cassette holder.

[Summary of the idea]

The cassette tape player of the present invention is a cassette tape player in which a cassette tape is inserted into a cassette holder to play the cassette tape, and the cassette tape is ejected by projecting the cassette tape forward from the cassette holder using a pusher. The middle part of the brake arm is pivotally supported on one side of the cassette holder so as to be able to swing freely in the thickness direction of the cassette tape, and the front end of the brake arm is supported on one side of the cassette tape in the thickness direction. Opposing brake bodies are provided, and an engaging part is provided at the rear end of the brake arm to face the other surface in the thickness direction of the cassette tape, so that either the brake body or the engaging part can be selectively operated. The brake arm is formed so as to come into contact with the cassette tape in the cassette holder, and the brake arm is biased in a direction in which the brake body comes into contact with the cassette tape,
When the cassette tape protrudes forward from inside the cassette holder, the brake body is brought into contact with the cassette tape to prevent the cassette tape from falling off.
