BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette housing for a cassette tape recorder.

[0002]

2. Description of the Related Art In a conventional cassette tape recorder, when a tape cassette is in a play state, that is, when the tape cassette is fitted to a tape drive mechanism, the tape cassette is positioned by three supports projecting from a deck surface of the tape drive mechanism. Was. However, in this case, there is a problem that the recording / reproducing signal becomes unstable due to mechanical vibration such as backlash. In addition, depending on the device, flat rubber or the like is attached to the cassette receiving housing surface from the viewpoint of stable mounting of the tape cassette as a measure for improving this. However, it is not possible to expect a good cassette to be stably mounted in the above-mentioned conventional one, and in the case where rubber or the like is stuck, the sticking operation is complicated, and the total performance is deteriorated due to deterioration of the rubber itself. I was worried.

FIG. 6 shows a simplified sectional view of a conventional tape drive mechanism in which a tape cassette is mounted.
A tape cassette 5 is mounted on a drive mechanism 4, support portions 2, 3 and the like provided on the deck 1. In a play state (not shown), the upper surface of the cassette is pressed by some method.

[0004]

In the above conventional apparatus, even if the tape cassette 5 is positioned at, for example, three points by the support portions 2, 3, etc., the tape cassette 5 is not affected by mechanical distortion or mechanical vibration on the deck side. It was not always satisfactory with a stable installation. SUMMARY OF THE INVENTION The present invention has been developed to solve the above-mentioned problems, and has as its object to provide a tape recorder which enables the cassette receiving housing to have a simple configuration.

[0005]

According to the present invention, in a cassette receiving housing, a soft resin plate is detachably provided on the cassette receiving housing, and the upper surface of the cassette receiving plate has at least three points of contact with the cassette surface. A plurality of columns extending downward are integrally provided on the lower surface of the plate, and the dimension from the tip of the projection to the lower end of the column is a cassette driving mechanism. The height is slightly longer than the height of the cassette positioning support portion installed on the surface.

[0006]

The soft resin plate has a three-point projection on its upper surface and an engaging portion and a plurality of columns formed integrally on its lower surface.
It is firmly engaged with the engaging portion. Since the dimension from the tip of the projection to the lower end of the support is slightly longer than the dimension of the cassette positioning support, first, when the tape cassette is inserted into the cassette receiving housing, its surface is received by the projection, and The cassette is pressed from above and moves down to the lower positioning support together with the housing and is mounted on the drive mechanism. At this time, the portion of the plate set slightly longer does not hinder the positioning at all due to the elastic bending, but rather contributes greatly to the stable mounting of the tape cassette by its elastic effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cassette receiving housing of a cassette tape recorder according to the present invention will be described below with reference to the drawings. FIGS. 1 and 2 are plan views and cross-sectional views of a soft resin plate mounted on a cassette receiving housing according to the present invention. Plate 6
The openings 16 and 17 into which the tape drive shaft is inserted, the relatively long protrusion 7 which receives the tape cassette surface by three-point contact, and the relatively short protrusion 8, 9 and slits 14, 14 ', 15, 15', etc. are provided. On the lower surface thereof, columns 10, 11, 12, 13 and an engaging portion 18, etc. are integrally formed as shown in a sectional view. It is provided in.

FIG. 3 is a plan view showing a state in which the plate 6 is mounted on the cassette receiving housing H.
Reference numerals 2 'and 3 denote support portions projecting from the cassette drive deck surface for positioning the cassette. Also, 1
Reference numerals 0 ', 11', 12 ', 13', and 18 'denote engagement holes provided in the cassette receiving housing.
It is inserted into and engaged with the support columns such as 2 and 13 and the engaging portion of 18.

FIG. 4 is a cross-sectional view of FIG. 3 showing a tape cassette (not shown) in a play state in which the tape cassette (not shown) is brought to the cassette drive deck surface by the cassette receiving housing. At this time, the struts 10, 1
The tip portions of 1, 12, 13 and the like are elastically pressed against the deck surface 1 while being slightly bent.

Next, the gist of the present invention will be described in more detail with reference to the enlarged views of FIGS. 5A and 5B. FIG.
FIG. 2A is a relational view showing a state in which the tape cassette 5 is mounted on the drive mechanism 4, and shows a positioning support section 3 provided in a manner projecting from the cassette drive deck surface 1 (in this case, the support section 3 up to the previous figure is shown). FIG. 3 is an enlarged view of a portion of the tape cassette, and the front end of the support portion 3 hits the lower surface of the tape cassette to perform positioning support.
That is, the dimension from the deck surface to its tip is Ls as shown in the figure.
Indicated by

On the other hand, FIG. 5B is an enlarged view of a portion related to FIG.
Although the tape cassette and the cassette drive mechanism are not shown in the figure, it shows a state in which the cassette receiving housing has brought the tape cassette into a play state,
The tip of the support 10 contacts the deck surface 1 with resilient pressure. In this case, the actual dimension from the top end of the projection 8 of the plate 6 to the top end of the column 10 is indicated by L as shown. As described above, the dimension of L and the dimension of Ls are in a relationship of L> Ls, though slightly.

Since the present invention has the above-described structure, when the tape cassette is pressed and mounted on the support for positioning the play position, the tape cassette is integrated with the plate 6 from the relationship of L> Ls. Due to the pressing contact of the tips of the plurality of pillars formed on the deck surface 1, the plate 6 generates a well-balanced bending as a whole, and a balanced and stable mounting to the tape cassette is performed.

[0013]

As is apparent from the above description, in the cassette tape recorder of the present invention, the plate 6 made of a soft resin can be easily and detachably mounted on the cassette receiving housing. And a plurality of pillars integrally formed on the lower surface thereof, the elasticity and the like in combination with the positioning support portion for the deck surface make it possible to provide an unprecedented quake resistance, a good stable positioning, and an effective operation without complicated work. The tape cassette can be stably mounted.
