Description

[Detailed Description of the Invention] The present invention provides a push button for operating a push button for switching operation circuits such as stereo, monaural, or band switching in a radio and a tape player, and an eject button in a tape player. A tape designed to reduce the number of operation buttons installed in a complex device by sharing the same operation button and allowing each operation to be performed independently using the common push button. This relates to the eject mechanism of the player, and will be described in detail below with reference to drawings that are examples.

In a composite device of a radio and a tape player, a first operation lever 2 of a push switch 1 for switching the operating circuit of the radio, for example, stereo and monaural or AM band and FM band;
2nd for eject operation in tape player
The operating rods 3 are provided so that they slide parallel to each other independently, and the second operating rod 3
A push button 4 is provided on the first operating lever 2 and the second operating lever 3, and when the second operating lever 3 slides by a stroke l or more necessary to eject the tape player, the first operating lever 4 is pressed. The first
An engagement step 5 and an engagement piece 6 are provided on which the operating rod 2 slides, and specifically, an engagement step 5 cut out in a U-shape is provided on the side edge of the first operating rod 2. An engagement piece 6 is provided on one side edge of the second operating rod 3, and this engagement piece 6
The other side of the second operating rod 3 is engaged with the engaging stepped portion 5 so that the push button 4 can move by a length of a stroke in the direction in which the push button 4 is pressed, and come into contact in the opposite direction. In addition, there is an ejector having an interval corresponding to the distance of the switching operation position of the switch 1, that is, the distance between the stereo position and the monaural position, and which also serves as a lock for the tape cartridge 7 when the tape cartridge 7 is pushed into the play state. engages with the actuating lever 9 of the mechanism 8 and the second operating lever 3
Two engaging portions 10 and 10' are provided for operating the actuating lever 9 in the eject direction within the range of the stroke 1 in which the engaging piece 6 moves freely within the engaging step portion 5 of the first operating rod 2. One is configured to be rotatable in only one direction by a spring 14 and a stopper 15, and furthermore, the first operating rod 2 has two engagement holes 11 with an interval corresponding to the distance of the operating position of the switch 1, 11' is provided, and when the tape cartridge is pushed into the play state, one end of the lever piece 12 that seesaws in relation to this is selectively engaged with the engagement holes 11, 11', and the first It is provided with an engaging pin 13 that restrains the forward sliding movement of the operating rod 2.

The present invention has the above-mentioned configuration, and is implemented, for example, in a push switch that switches between stereo and monaural operation circuits of a radio, and when the tape cartridge 7 is pushed into the play state, when the stereo , as shown in FIG.
0, the end of the actuating lever 9 engages with the switch 1, and in the monaural mode, as shown in FIG. The engagement pin 13 engages with the hole 11',
The end portion of the operating lever 9 is adapted to engage with the second fixed engagement portion 10' of the second operating rod 3.

When the push button 4 of the second operating rod 3 is pressed from the state shown in FIG. When the push button 4 is pressed further, the engagement hole 11 of the first operating rod 2 and the engaging pin 13 engage with each other, causing the first and second operating rods 2 and 3 to move freely. is prevented from advancing, so that switch 1 is not switched. On the other hand, as the second operating rod 3 moves freely, the engaging portion 10 pushes the end of the operating lever 9, and the lever 9
When the lever 9 rotates counterclockwise, the other end of the lever 9 applies a counterclockwise rotational force to the ejector lever 8a, and the lever 8a rotates about the support shaft 8b, thereby releasing the tape cartridge. When the engagement shaft 8c engaged with the engagement recess 7a of No. 7 is disengaged, the pushing piece 8d of the ejector lever 8a moves the operating piece 8e, and the tape cartridge 7 engaged with this moves. , is ejected toward you. In other words, the state shown in FIG. 2 is reached, and in this state, the protruding shaft 13', which is provided at the inner end of the lever piece 12 that seesaws and is pushed down by the tape cartridge 7, is released as the tape cartridge 7 is ejected. As a result, the engagement pin 13 provided at the outer end of the engagement pin 13 automatically descends and leaves the engagement hole 11. Therefore, from this state, if push button 4 is pressed, switch 1 can be switched from the stereo position to the monaural position, and in the monaural state, the switch 1 can be switched from the stereo position to the monaural position.
The second operating rods 2 and 3 are both placed in a position a distance advanced from the switching operation position of the switch 1. In this state, when the tape cartridge is set in the tape player, the state shown in Fig. 3 is obtained. In this state, when push button 4 is pressed, the same effect as in Fig. 1 is performed, and switch 1 is moved from the monaural position. The tape cartridge can be ejected without being switched to the stereo position.

Note that the above shows a state in which the engagement step portion 5 is cut out in a U-shape, and the engagement piece 6 is pressed against the rear edge 5'' by the restoring spring 16 of the second operating rod 3. According to the above, it is possible to easily detect from the outside whether the switch 1 is in the stereo position or the monaural position, depending on the length of the push button 4 protruding from the front surface of the device frame A.

As described above, according to the present invention, in a combination device of a radio and a tape player, the operating push button of the push switch for switching the operating circuit of the radio can be used as the eject operating push button of the tape player. This not only makes it possible to reduce the number of push buttons placed on a complex device, but also ensures that the initial change operation of the operating circuit in a radio and the eject operation in a tape player do not affect each other's operations. It has the advantage of being able to perform
