Description

[Detailed description of the invention] Conventionally, in a cassette tape recorder, the operation section 2 provided with operation buttons for recording, playback, etc.
As shown in the figure or Fig. 2, the cassette holder 1
Therefore, in order to make this tape recorder compact, it is necessary to consider the arrangement of the operating section 2, which occupies a large area.

In the case of Fig. 1, the operating section 2 is the cassette holder 1.
Since it is installed on the lower side of the screen, the width can be reduced, but it cannot be made very thin. The case shown in FIG. 2 can also be made slightly thinner than the case shown in FIG. Therefore, in this invention, the cassette holder 1 is placed on the rotation fulcrum side of the cassette holder 1 and overlapped with the cassette holder 1.
By mounting the operating section 2 so that it can move in conjunction with the rotation of the cassette holder 1, it is possible to make the cassette-type tape recorder thinner without interfering with the operation of the cassette eject and the operation of the operating section 2. This is what I did.

FIG. 3 is a front view of a cassette-type tape recorder to which this invention is applied, in which a plurality of operation buttons 3 are all attached to the front surface of the cassette holder 1 on the side of the pivot point of the cassette holder 1. Therefore,
A bottom panel (not shown) of the tape recorder will soon be located on the bottom side of the operating section 2.

FIG. 4 is a perspective view for explaining the structure of the main parts of this invention, in which the cassette holder 1 is in a closed state. A pair of substrates 4 and 5 are planted facing each other on the chassis 31 at a predetermined interval.
A plate-shaped mounting plate 6 is rotatably mounted across the pair of substrates 4 and 5. The mounting plate 6 has both ends bent to form a U-shape as a whole, and an L-shaped arm 7 facing one of the substrates 4.
is rotatably supported by a support shaft 8 provided on the substrate 4. The other L-shaped arm 9 is also supported by a similar support shaft 10 (see FIG. 6).
These arms 7 and 9 rotatably support the cassette holder 1 by shafts 32 and 33 provided at their respective ends. On the other hand, guide grooves 12 and 1 are provided in the substrates 4 and 5 in a direction perpendicular to the surface of the chassis 31.
3 is formed in the bent portion of the cassette holder 1 opposite to the guide grooves 12 and 13.
2 and 13, guide elements 14 and 15 are set up, and the cassette holder 1 is guided. Note that 34 and 35 are collars attached to the guides 14 and 15.

On the other hand, an L-shaped protrusion 16 is formed on the arm 7 of the mounting plate 6, and as shown in FIG. The mounting plate 6, and therefore the cassette holder 1, are always biased in one direction by a spring 18 that is compressed between this tip and the base plate 4.
Although the protruding piece 16 and the spring 18 are provided only on one arm 7 as shown in the figure, a similar structure may be applied to the other arm 9.

On the other hand, on the substrate 5 side of the cassette holder 1, a mechanism for opening the cassette holder 1 associated with the eject operation button 19 is provided. Reference numeral 20 denotes a rod with an eject operation button 19 attached to the tip thereof, and is slidably engaged with a pair of holes 21 and 22 formed opposite to each other in the board 5. It is normally biased toward the hole 21 by a spring 24 that is compressed between the upper projection 23 and the upper projection 23 . Further, the rod-shaped portion 37 engages with the lower protrusion 36 of the rod 20, and the L-shaped rod 25
is provided, and when the rod 20 moves toward the hole 22, the L-shaped rod 25 is rotated clockwise about a shaft 26. Further, the L-shaped rod 25 is connected to a movable member 28 on which a pin 27 that contacts the cassette holder 1 is installed on the surface facing the cassette holder 1, and a pin (not shown) installed here. are adapted to engage with each other. Further, the moving member 28 is engaged with a pin 39 having a flange 38 set on the base plate 5 through an L-shaped groove 40 bored in the center thereof. On the other hand, although not shown, a spring is installed between the moving member 28 and the substrate 5, and the moving member 28 is normally biased downward by its elasticity. Then, when the above-mentioned L-shaped rod 25 rotates clockwise about the shaft 26, this moving member 28 faces above the cassette holder 1 while along the L-shaped groove 40, and also moves toward the cassette holder 1. Move slightly to the front. As the moving member 28 moves upward, the pin (not shown) that is set on the side of the cassette holder 1 and is engaged with the guide groove 13 of the substrate 5 is released from the locked state by the moving member 28. be done. Then, when the pin 27 installed on the moving member 28 presses the cassette holder 1 forward while coming into contact with the rear end surface of the cassette holder 1, the cassette holder 1 is moved to the shaft (not shown) to which the mounting plate 6 is attached. ) rotates clockwise around the center. Then, the cassette holder 1 is brought into a state where it is easy to insert a cassette (not shown) through the cassette insertion opening 41 as shown, and the ejecting operation is thereby completed.

By the way, the U-shaped mounting plate 6 has playback, recording,
Various operation buttons 3 such as a stop operation button are arranged in a line extending in the longitudinal direction. The operation system of the tape recorder according to this invention is constructed purely electronically, so that the corresponding operation mode can be easily selected by simply touching an operation button. Therefore, since the plurality of operation buttons 3 arranged on the mounting plate 6 only include a switch mechanism, it is possible to arrange operation buttons for recording, etc. on the mounting plate 6 as shown in the figure. .

In addition, when the cassette holder 1 is closed and the mounting plate 6 is slightly opened upward as shown in FIG. has been selected.

The reason why the mounting plate 6, and hence the multiple operation button 3, are made to face upward when the cassette holder 1 is closed is in consideration of operability during use of the tape recorder. That is, when the cassette is removed from the tape recorder, the recording and playback operation buttons 3 are not used, but when the cassette is attached, various operations need to be performed. This is because if it were installed, the above-mentioned mode selection would be inconvenient and the operability would be significantly hindered. Further, if the operation button 3 is oriented upward as shown in the figure, the operability is significantly improved. Note that the upward angle of this mounting plate 6 does not need to be very large. This is because, as mentioned above, the operation button 3 is a so-called touch type, and various operation modes can be selected purely electronically.

Next, the closing operation of the cassette holder 1 of the cassette type tape recorder according to the present invention will be explained together with the rotating operation of the mounting plate 6.

First, the cassette insertion port 41 of the cassette holder 1
A cassette (not shown) is inserted into the cassette holder 1, and the front surface of the cassette holder 1 or the front surface of the U-shaped mounting plate 6 is pressed by touching it with a hand.
The U-shaped mounting plate 6 rotates counterclockwise around the shaft 8, etc., and moves integrally with the cassette holder 1 while remaining parallel to it until the guide 14 moves along the grooves 12, 13 to a position approximately above the shaft 8 (see Figures 7 and 8).

When the engaging pin 14 and the like move past the position substantially above the shaft 8 and move further toward the chassis 31, the U-shaped mounting plate 6 that has been moving together with the cassette holder 1 is centered around axes 32 and 33,
By rotating clockwise in the illustration, the cassette holder 1 is brought into a closed state (see FIG. 6).

Note that when operating the operation button 3, a force is applied in the direction of the support shaft 8, etc. or downwardly of the support shaft 8, etc., so that even if the operation button 3 is pressed, there is no possibility that the cassette holder 1 will move unnecessarily.

In this way, the cassette holder 1 and the mounting plate 6 rotate about the support shaft 8 from the state shown in FIG. Since only the plate 6 rotates around the shafts 32 and 33, even if the mounting plate 6 is parallel to the cassette holder 1 in the state shown in FIG. 5, FIG. 7, and FIG. 8, the cassette holder 1, the mounting plate 6 further rotates counterclockwise around the support shaft 32, so eventually the mounting plate 6 stops at a predetermined angle with respect to the cassette holder 1 and the operation button is pressed. 3 becomes easier to press.

Thus, according to the cassette tape recorder according to the present invention, since the operation section 3 can be placed within the space of the cassette holder, it can be formed thinner than in the case of FIGS. Miniaturization can be achieved. Further, in this embodiment, since the operation button is oriented slightly upward when the cassette is stored, the operability of the operation button can be greatly improved.

Furthermore, since the cassette holder 1 is not moved even if the operation button 3 is pressed, there is no risk of the cassette holder being opened accidentally.
