Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a tape recorder in which a tape running device for running a magnetic tape in a cassette tape is detachably attached to the main body of the device.

Conventional configurations and their problems In recent years, tape recorders have tended to be used for multiple purposes. For example, when used indoors, etc., a tape running device that runs the magnetic tape of the cassette tape is attached to the main body of the device in order to listen to high-capacity audio through speakers, etc., and when used outdoors, etc., it is used as a portable device. A method is used in which the tape running device is detached from the main body of the apparatus and the audio is heard through a headphone or the like.

Furthermore, car stereos and the like tend to be used for multiple purposes, such as by integrating the car stereo main body and the car stereo system and installing it inside the car for use inside the car, or by removing it from the car and using it outside or inside the car.

On the other hand, in a tape recorder, most of the parts that require repair service after long-term use are tape running system parts such as magnetic heads, belts, and motors. Therefore, there is a demand for improved workability during repair services.

First, in conventional tape recorders, when the tape running device is attached to and detached from the main body of the device, a cassette mounting means such as a cassette holder is provided integrally with the tape running device.

Therefore, when used as a portable device, it becomes larger and
There were also other problems, such as weight.

In particular, in order to improve the operability of loading and unloading the cassette, the cassette loading means reciprocates between a first position for loading and unloading the cassette tape and a second position for loading the cassette tape on the tape transport device. A tape recorder equipped with a cassette transfer means, generally called a slot-in type, which automatically transfers a cassette tape to a second position when the cassette tape is inserted from the cassette insertion slot in the second position, has a complicated structure. This was noticeable due to the large number of parts.

In addition, if you remove the car stereo body or car stereo system from the car and use it,
Since the main body of the device must be removed for use, it is too large and heavy for portable use, making it very inconvenient.

Purpose of the invention The present invention solves the above-mentioned conventional problems.
The tape running device detached from the main body of the device provides a compact and lightweight tape recorder that can be used, and improves the workability of repair services, etc., and when the tape running device is attached to the main body of the device, the operation of loading a cassette tape is easy. It provides a simple tape recorder.

Structure of the Invention The present invention has a tape running device that runs a magnetic tape of a cassette tape attached to and detachable from the main body of the device.
This tape recorder is equipped with a cassette mounting means for attaching and detaching a cassette tape to and from a tape running device attached to the main body of the device. It is lightweight and usable.

Further, the cassette mounting means is capable of reciprocating between a first position for mounting and dismounting the cassette tape and a second position for mounting the cassette tape on the tape transport device, and the cassette tape is mounted in the cassette at least in the first position. This tape recorder is designed to be automatically transferred to the second position when inserted through the insertion opening, and the cassette tape can be easily loaded.
