[Detailed Description of the Invention] Technical Field The present invention relates to an operating mechanism for a) J set tape deck;
Especially the so-called kangaru-pocket power set 1-hori-
This is a description of the operating mechanism for a cassette tape deck equipped with a cassette tape deck.

Back■Technology Recently, combo-screw 1 ~ stereo A smell-C is small 1
There is a trend towards high performance, and various so-called mini-combo stereos are being released. Is it easy to downsize components such as diconators and amplifiers that mainly consist of electric circuits?
In the case of cullet tape, which relies mainly on the 4th part, it is difficult to downsize. In particular, in the case of a so-called double deck, which has parts on two decks so that dubbing can be performed, one unit is required for two units, so it is more difficult to downsize, and it is difficult to make it smaller than the conventional size. A minicombo miniaturized to the point where it can be compatible with the stereo A and C has not yet been developed.

An object of the present invention is to provide a cassette tape deck operating mechanism which has been developed in view of the above points and which can be maintained for a long time.

In the operating mechanism of the cassette tape deck according to the present invention, the plate on which the switch is removed is mounted so as to be displaceable with respect to the deck body via the bracket rL. A panel having a hole to be attached to the panel and the bracket are respectively formed, and the panels are attached to each other, thereby allowing the relative positioning of the switch operator and the hole in the panel. .

Example Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

1 to 3, the cassette tape deck 1 according to the present invention is a so-called double cassette deck suitable for dubbing, which includes two deck parts 2A and 2B, and includes an operating part, a mechanism part, and It is composed of two blocks: a main body part 3 including a control part, and a power supply part 4 connected to the rear part of the main body part 3, and in combination with other components 1 to 1 such as an amplifier and a tuner, it creates a so-called mini component stereo. It has been miniaturized for use. Four leg receivers 5 are formed on the upper surface of the main body 3 to fit with the legs of other components 1- to be placed and to prevent misalignment of the components.

One of the two deck parts 2A and 2B
A is for playback only, and the 1m deck section 2B is capable of recording and playback. Deck part 2△ for reproduction only,
Since the bluff 1 part 2B for recording/reproduction basically has the same configuration as each other, the details of the differential 4 part 2 will be mainly described below.

To load the cassette 1, hold the cassette half 6 (shown in the third figure) in an upright position and place it in the so-called upright Kangaru-pocket type J set holder 7A, which can be opened and closed from the storage section of the JJ set 1. Yotsu'C is done. Cassette holder 7
A is swingably supported by a pivot shaft 8 at the upper end of an arm portion 7a that projects forward from the front surface of the holder in the closed state (as shown in FIG. 5), and is mounted around the pivot shaft 8. A first spring 9 has one end engaged with the chassis and the other end engaged with each of the Karen 1 to holder 7A, and a second spring 10 with one end engaged with the lower part of the h set holder 7Δ and the other end engaged with the chassis. The two springs 9.10 are applied to the entire swing range of the cassette 1 - small router - 7△. (=J force (=J
However, in the open state of cassette i to holder 7A shown in FIG. It is located on a - straight line with the axis of the support shaft 8, and does not apply a rotational moment to the cassette holder 7A (+), so the force is directed from 1 to holder 7A (+) in the direction of In the first half of the oscillation, the fKl force horn of spring 9 mainly burns and acts on holder 1 to holder 7AI, and spring 9
In the second half of the swing when the force of A is weakened, the biasing force of the spring 10 mainly acts on the cassette l-holder 7Δ,
The sum of the (=J forces) of both springs 9 and 10 is approximately constant over the entire swing range of the cassette holder 7A. The same can be said when the cassette holder 7 swings in the closing direction. .

By the way, the cassette holder 7A is operated by a damper (not shown) so that the sound is heard slowly.

The bracket 12A is swingable (supported by the spring 16, and the bracket 12A is supported on the spring 16 in the J direction (Fig. 3). The bracket 1-12[Delta][mu] is biased by a means (not shown) provided between the holder main body 11[Delta] and the bracket 12A.

This is effective when using tape or metal tape. Thereafter, the holders 1 to 7A are further swung in the opening direction mainly by the force of the spring 10, and are gently swung by the action of a damper (not shown).

The operations of cassette 1 to load/manipulate C on the deck section 2A side have been described above, but similar operations are performed on the deck section 2B side.

With the above configuration, the operation switches and display elements of C1, which were previously placed outside the power set 1~holter, can be replaced with the cassette 1.
- In addition to being able to be placed inside the boulder, the lock 1jll of the cassette holder and other mechanisms related to the opening/closing operation of the forcelet holder could be stored within the frame of the Pobocaren 1 holder, as is clear from Figure 12. In particular, check the size of the cassette tape deck 1 in the horizontal (width) direction.
The size can be reduced to approximately 2 WA of the half 6 (indicated by the two-dot chain line 1-), and the world's smallest double power set 1 deck has been obtained.

Moreover, it is not limited to the concept of the conventional Mini Composer PreΔ, and is not only a stationary type, as shown in Figure 12.

It is integrated into a portable Suare A device and -C is also used. Any combination U with other components 1 to 7, such as a micro cassette deck and a digital A-disk player 7, is possible.

J3, in the above embodiment, the case where it is applied to the tuple tjLz1~deggi was explained, but the present invention is not limited to application to a double force hit deck, but is applicable to a deck having a single deck part. It can also be applied to J as shown in Figure 12.
It can be miniaturized to approximately half the size of a double decker, making it the world's smallest tape deck compatible with component stereo.

Effects As explained above, according to the present invention, the board from which the switch is removed is attached via a bracket so as to be displaceable with respect to the deck body, and the hole through which the operator of the switch is inserted is provided. Since positioning means are provided on the panel and the plaque, respectively, and are fitted into each other when the panel is installed, the switch operator and the hole in the panel are positioned relative to each other, so assembly is easy. In addition, even if the circuit board deforms due to aging, the positional relationship between the switch operator and the hole in the panel can always be kept constant, resulting in excellent operation. This provides an operating mechanism that can maintain its performance over a long period of time.
