Description

[Detailed Description of the Invention] The present invention relates to a cassette holder for a tape recorder, and more specifically, the present invention relates to a cassette holder for a tape recorder. It is an object of the present invention to provide a cassette holder equipped with a shaped elastic member.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Referring to FIG. 1, a linear elastic member applied to one embodiment of the present invention is generally designated by the numeral 1.

This linear elastic member 1 can be formed of a metal wire 2 having an elastic force as shown in the figure, and a third
Both side walls 11 of the cassette holder 10 shown in the figure
Small holes 12a formed in a, 11b, respectively,
The locking portion 3a is adapted to be fitted into the locking portion 12b.
, 3b are formed.

As shown in the figure, these locking parts 3a and 3b bend both ends of the metal wire 2 at right angles, and further bend the tips of the parts bent at right angles to face each other. It can be formed by

Note that the locking portion may be formed only at one end of the metal wire 2.

Further, the metal wire 2 has a non-wound bent protrusion 4 formed at an appropriate position between the two ends of the metal wire 2 by simply bending the metal wire 2 into, for example, a wave shape without winding it as shown in the figure. is provided.

This protrusion 4 is a locking portion 3a. 3b, the end of the metal wire 2 is formed to protrude in a direction opposite to the direction in which it was first bent at right angles.

The linear elastic member 1 having the above configuration is attached to the cassette holder 1 by attaching its locking portions 3a and 3b as described above.
A pair of locking and rotating bearing pieces provided on the back of the back wall 11C of the cassette holder 10 are fitted into the holes 12a and 12b of When inserted between 13a and 13b and the back wall 11C and mounted on the cassette holder 10, the protrusion 4 projects outward from the back wall 11C at a substantially right angle as shown in the figure. Orientation is required.

The cassette holder 10 with the linear elastic member 1 attached thereto is installed behind one wall 22 of a cassette storage recess 21 provided in the tape recorder main body 20, as shown in FIG. The pair of bearing pieces 13a and 13b are rotatably engaged with the shaft 23, which is attached to the tape recorder body 20.

In this case, the linear elastic member 1 attached to the cassette holder 10 has its protruding portion 4 brought into contact with the wall 22 of the recess 21 of the tape recorder main body 20, and has an elastic force directed toward the cassette holder 10 in the direction of opening it. The back wall 11C and the wall 22 of the cassette holder 10 are
It is placed between.

Therefore, in this case, the elastic force is
It will be easily understood that this is caused by the protrusion 4 being twisted about the fulcrum.

FIG. 4A shows the cassette holder 10 closed against the elastic force, and FIG. 4B shows the cassette holder 10 opened by the elastic force. In this state, the pair of locking pieces 14a and 14b provided on the cassette holder 10 lock into appropriate engaging portions of the tape recorder main body 20 (not shown), preventing the cassette holder 10 from opening any further. It is designed to prevent

Although one non-wound bent protrusion 4 is formed on the illustrated linear elastic member 1, a plurality of protrusions 4 may be provided as necessary.

Furthermore, although the protruding portion 4 shown in FIG. 1 has a shape almost like a half-wave of a sine wave, the shape can be selected depending on the desire. Although these examples illustrate other suitable shapes of the protrusion 4, it goes without saying that shapes other than these may also be used.

As can be understood from the above explanation, since the elastic member attached to the cassette holder according to the present invention is formed of a linear body such as a metal wire, it occupies a small space and has a compact structure. This makes it possible to use it even in very narrow spaces.

Further, since the cassette holder can be attached simply by fitting the locking portion provided at the end into the hole of the cassette holder, assembly is easy.

Furthermore, since dimensional errors can be absorbed in the non-wound bent protrusion mentioned above, strict dimensional accuracy is not required.
Easy to manufacture.

In addition, in a cassette holder equipped with such an elastic member, the torsion of the protruding portion is maximum when the cassette holder is closed, so the spring force of the elastic member is small.
Therefore, it has practical benefits such as being able to easily close the cassette holder.

[Brief explanation of the drawing]

FIG. 1 is a plan view showing an example of a linear elastic member attached to a cassette holder according to the present invention, FIGS. 2A to 2E are views illustrating the shape of a protrusion formed on the elastic member, and FIG. A fourth perspective view showing an example of the cassette holder according to the present invention.
The figures are schematic cross-sectional views showing the state in which the cassette holder is attached to a tape recorder body, with FIG. 4A showing the cassette holder in a closed state and FIG. 4B showing it in an open state. In the figure, 1 is a linear elastic member, 2 is a metal wire, and 3a. 3b is a locking portion, 4 is a non-wound bending protrusion, 10 is a force set holder, 11a, 11b are side walls of the cassette holder, 11C is a back wall, 12a, 12b are holes, 20 is a In the main body of the tape recorder, reference numeral 21 indicates a recess, and reference numeral 22 indicates a wall.
