3, and a retaining member 19 is housed in a through hole 21 formed in the upper surface of the housing body 11 so as to be slidable in the vertical direction, and is constantly urged upward by a spring. Due to its unique structure, it is impossible to manufacture it all at once using plastic molding, etc., and complicated assembly work is essential.Furthermore, the lead wires from the magnetic head are passed through the lead wire insertion holes 29 into the housing. Since it is guided into the main body 11, there is a problem in that it requires a large number of manufacturing steps, which hinders cost reduction.

The present invention has been developed with attention to these points, and makes it possible to manufacture housings for cassette tape decks all at once by molding plastic, etc., and also allows the lead wires from the magnetic heads to be easily placed inside the housing body 11. This is to realize a housing for a cassette tape deck that can be easily guided.

(Means for Solving the Problems) Therefore, in the present invention, a housing main body is formed in a box shape and has a magnetic head mounting portion and a capstan insertion hole on the upper surface, and an integrated housing body is provided on the upper surface of both sides of the housing main body. a pair of side guides projecting from each other and having an interval set to be approximately equal to the width of the tape cassette; and a pair of side guides projecting integrally from the top of both sides of the housing main body. an eave-shaped upper surface stopper extending from the top surface of the housing body and having a distance from the top surface of the housing body set to be approximately equal to the thickness of the tape cassette; The housing for the cassette tape deck is composed of a retaining protrusion arranged at a position where it comes into contact with the rear surface of the tape cassette when a predetermined portion contacts the magnetic head and capstan, and the cassette tape deck housing is constructed of a retaining protrusion arranged at a position where it contacts the rear surface of the tape cassette when a predetermined portion contacts the magnetic head and capstan. A lead wire insertion slot is provided which communicates with the side surface of the housing body.

(Function) In the housing for the cassette tape deck of the present invention constructed as described above, the lead wire from the magnetic head is guided into the housing body through the lead wire insertion slot, and the tape cassette is guided through the side guide and When the tape cassette is inserted while being guided by the top stopper and the predetermined portion comes into contact with the magnetic head and capstan, the retaining protrusion engages with the rear surface of the tape cassette to prevent the tape cassette from coming out. Since the upper surface stopper is formed in the shape of an eave, there is no support for assembly work such as attaching the magnetic head even if it is not configured to be removable, and the tape cassette is not attached even if the retaining protrusion is not configured to be slidable. It is easy to insert and remove, and it can be securely secured.

(Example) Next, an example of implementation of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a housing for a cassette tape deck according to the present invention. In the figure, numeral 31 is a box-shaped housing body made of plastic material, and a magnetic head mounting portion 33 and a capstan 35 are provided on the top surface of the housing body.
etc. are arranged. Reference numeral 37 denotes a pair of side guides, which, like the conventional ones, protrude integrally from both sides of the upper surface of the housing body 31, and the interval between the side guides 33 is set approximately equal to the width of the tape cassette to be used. has been done.

Reference numeral 39 indicates a retaining protrusion, and the housing body 31
It is integrally protruded from the top surface. The position of the retaining protrusion 39 is set so that a predetermined portion of the front surface contacts the rear surface of the tape cassette which is in contact with the magnetic head and capstan. Reference numeral 41 denotes a support member that integrally projects from both sides of the upper surface of the housing body 31 in the vicinity of the magnetic head mounting portion 33 and the capstan insertion hole 35. Reference numeral 43 designates an upper surface stopper that protrudes inward from the upper end of the support member 41 in the shape of an eave. The distance between the upper surface stopper 41 and the upper surface of the housing body 31 is set approximately equal to the thickness of the tape cassette, and the upper portions of the magnetic head mounting portion 33 and the capstan insertion hole 35 are not covered by the upper surface stopper 43. do not have. A lead wire insertion slot 45 communicates with the side surface of the housing body 31 from near the magnetic head mounting portion on the upper surface of the housing body 31, and opens at the lower end of the side surface of the housing body 31.

In the cassette tape deck housing of this embodiment constructed in this way, the tape cassette is inserted while being guided by the side guides 37 and the top stopper. When a predetermined portion of the front surface of the inserted tape cassette comes into contact with the magnetic head and capstan, a retaining protrusion 39 engages with the rear surface of the tape cassette to prevent it from coming out. Therefore, even if the retaining protrusion 39 does not have a slidable structure, it is possible to easily insert and remove the tape cassette and to securely retain the tape cassette. Further, since the upper surface stopper 43 is formed in the shape of an eave and does not cover the upper portions of the magnetic head mounting portion 33 and the capstan insertion hole 35,
Even if the structure is not particularly removable, there is no support for assembly work such as attaching the magnetic head. Also, the lead wire from the magnetic head is inserted through the lead wire insertion slot hole 45.
It is guided into the housing body 31 through.

(Effects of the invention) The present invention is constructed as described above, and the lead wire from the magnetic head is guided into the housing main body through the lead wire insertion slot, which eliminates the need to pass the lead wire through the hole each time, reducing the number of wiring man-hours. In addition, since the top stopper is shaped like an eave and does not cover the magnetic head mounting part, capstan insertion hole, etc., it is easy to install the magnetic head even if it does not have a removable structure. The tape cassette is inserted while being guided by the side guides and the top stopper, and when the predetermined portion comes into contact with the magnetic head and capstan, the retaining protrusion locks the tape cassette. The housing for the cassette tape deck is made of plastic because it engages with the rear surface and prevents the tape cassette from coming out, making it easy to insert and remove the tape cassette and securely prevent the tape cassette from coming out without having to make the retaining protrusion slidable. This makes it possible to perform bulk manufacturing by molding, etc., which has the excellent effect of reducing the number of manufacturing steps and making it possible to significantly reduce costs.
