Abstract

PURPOSE: To eliminate the possibility of a code breakage by providing the one angle part on the rear surface of a cassette adapter with a step part constituted of a first wall surface parallel with the rear surface wall and a second wall surface parallel with the side face wall, integrally forming a fitting part for a cord to the first wall surface and fitting this cord to this fitting part for the cord. CONSTITUTION: The reproduced signals from an external acoustic apparatus are transmitted via the cord 3 to a sound recording head 2 contg. a cassette adapter CA. This sound recording head 2 is magnetically coupled to a playback head 15 of a cassette deck and transmits the reproduced signals to the cassette deck. The one angle part of the rear surface of the cassette adapter CA is provided with the step part 19 constituted of the wall surface 20 parallel with the rear surface wall 6 and the wall surface 21 parallel with the side face wall 7. The fitting part 22 for the cord is integrally formed at the wall surface 20. The fitting part 22 consists of two pieces of fitting projections 22a and fitting grooves 22b and eliminates the possibility of the cord 3 breakage at the time of attaching and detaching the cassette adapter CA to the cassette deck by fitting the cord 3 to the fitting part 22.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette adapter, and more particularly to a cassette adapter which is mounted on a cassette deck to reproduce an external sound reproduction signal from an audio device such as a CD player on the cassette deck.

[0002]

2. Description of the Related Art When it is desired to reproduce an audio reproduction signal from an audio reproduction device such as a CD player on a cassette deck,
There is a cassette adapter which is mounted on a cassette deck and used when reproducing a reproduction signal from a portable CD player in a car stereo. Such a cassette adapter is arranged inside a housing having the same outer shape as a standard cassette for a cassette deck and the entire surface of the housing so as to be magnetically coupled to a reproducing head of the cassette deck when mounted on the cassette deck. It has a recording head and a cord for supplying an external sound reproduction signal to the recording head, and has a structure devised particularly for derivation of the code, for example, FIG. 5 of Japanese Patent Publication No. 4-56391. Some of the structures can be seen in Figures 7A and 7B.

[0003]

However, the above-mentioned conventional structure has a drawback in that the conductor device for guiding the external sound reproduction signal to the recording head in the cassette adapter is easily disconnected. An object of the present invention is to provide a cassette adapter which eliminates the above-mentioned drawbacks of the conventional structure.

SUMMARY OF THE INVENTION A cassette adapter according to the present invention has a housing having the same outer shape as a standard cassette for a cassette deck, and is magnetically coupled to a reproducing head of the cassette deck when mounted on the cassette deck. A recording head arranged inside the front of the housing,
In a cassette adapter provided with a cord for supplying an external sound reproduction signal to the recording head, a first wall surface parallel to a rear wall of the housing is provided at one corner of a rear surface of the housing, and a housing wall of the housing. A step portion including a side wall and a second wall surface parallel to the side wall is provided, and a cord fitting portion is integrally formed on the first wall surface, and a connecting portion between the first wall surface and the second wall surface. The cord is led out from the vicinity and fitted in the fitting portion.

The fitting portion is composed of two fitting protrusions and a fitting groove formed between the fitting protrusions for fitting the cord. The cord is led out from the vicinity of the connecting portion in a direction parallel to the side wall inside the housing, bent after being led out, and fitted in the fitting groove of the fitting portion.

Further, the cassette adapter according to the present invention is
A protector member is attached to the step portion, and the protector member includes a first recess for leading out the cord fitted in the fitting portion. The protector member is elastically fitted and attached to the fitting protrusion of the fitting portion. Further, the protector member may include a second recess for guiding the cord along the second wall surface.

[0007]

The cord of the cassette adapter is integrally formed on a first wall surface which is a first wall surface forming a step portion provided at one corner of the back wall of the housing and which is parallel to the back wall of the housing. Since it is fitted in the fitting portion, there is no fear that the cord will be cut when the cassette adapter is attached to or removed from the cassette deck. Further, the protection of the cord is further enhanced by mounting the protector member on the step portion.
