Next, the operation of the switch operation control mechanism 12 having such a configuration will be explained.

First, during normal use when the telephone main body 1 is used together with the stand 2, the switching knob 14 is set in advance to the solid line position in FIG. 1 (first position), and the telephone main body 1 is taken up from the stand 2. In this case, the hook button 13 is held in the position shown by the solid line in FIG. At this time, the letter "ON" displayed on the surface of the knob 14 indicates the knob mounting hole 4 as shown in FIG.
5 and will be visible. Further, the switching knob 14 is prevented from moving to the left because the position setting projection 44 is located to the right of the knob locking projection 63 of the lever receiver 25 in FIG.

In this state, the hook switch 9 is released from the actuator 29 of the hook button 13,
The telephone main body 1 is held in a talking state. When the phone body 1 is returned to the stand 2 after the call ends, the hook button 13 hits the actuating part 20 of the stand 2 and is pushed up, so the actuator 29 rotates the actuating piece 9A against the spring 36, and this When the switch 9 is opened, the telephone line is returned to the disconnected state. At this time, the operating lever 24
is rotated clockwise in FIG. 1 against the coil spring 52 by the upward movement of the hook button 13. Here, since the projection 21 for preventing forgetting to switch on the mounting base 2 is provided corresponding to the left half of the knob mounting hole 45 as shown in FIG. 1, the switching knob 14 is in the first switching position. Sometimes, it does not come into contact with the operating section 40, but fits into the knob attachment hole 45. Therefore, the telephone body 1 is stably placed on the stand 2.

Next, if you do not want to use the stand 2 and want to place it in a suitable place such as a desk, stand, shelf, etc., move the switching knob 14 to the left in Fig. ). Switching knob 14
When moved to the left, the position setting protrusion 44 pushes up the knob locking protrusion 63, and as the protrusion 63 moves to the left, the switching knob 14 is held at the second position. In addition, the arm 61 of the lever receiver 25
When the protrusion 63 climbs over the protrusion 44, the first
It deforms elastically upward in the figure, giving a rickety feeling to the hand.
When the switching knob 14 is switched to the second position, the lever pressing portion 43 presses the contact portion 24D of the operating lever 24 to the left in FIG.
4 rotates clockwise against the coil spring 52,
The button drive section 24C pulls the hook button 13 into the button attachment hole 32 to the position shown by the two-dot chain line in FIG. Then, the actuator 29 of the hook button 13 presses and rotates the operating piece 9A of the hook switch 9 against the spring 36, thereby closing the switch 9. Therefore, the result is the same state as if the telephone body 1 were placed on the stand 2. In this state, if you receive an incoming call and wish to make a call, simply return the switching knob 14 to the first position shown by the solid line in FIG. Then, actuating lever 2
4 is rotated counterclockwise in FIG. 1 by the force of the coil spring 52 to move the hook button 13 downward in FIG.
3 is released from the actuator 29, and becomes ready for communication. After the call is over, the switching knob 14 is switched again to the second position shown by the two-dot chain line in FIG. 1, and in conjunction with this, the operating lever 24 moves the hook button 13 upward in FIG. By doing so, it returns to the disconnected state. Therefore, there is no need to take the trouble to return the telephone main body 1 to the stand 2.

That is, when the stand 2 is not used, the switching knob 14 and the operating lever 24 serve as the actuating part 20 of the stand 2.

Here, it is also conceivable to return the switching knob 14 to the second switching position and return the telephone body 1 to the stand 2 after the call. In that case, the actuating part 20 of the stand 2 will fit into the button mounting hole 32 as shown in FIG.
Since the telephone body 1 comes into contact with the operating part 40 and is prevented from entering the knob mounting hole 45, the telephone main body 1 is kept in an inclined state. Therefore, the stability of the telephone main body 1 is poor and the user can be made aware of forgetting to switch the switching knob 14 when used together with the stand 2.

〔Effect of the invention〕

As explained above, according to the one-piece telephone switch operation control mechanism according to the present invention,
Not only can it be used as a set with a stand as before, but it can also be used to switch between call and disconnection states without having to return it to the stand, so it can be used when carried far away from the stand. In addition, there is no need to take the trouble to return the phone to the place where the stand is installed, making it extremely convenient to handle.
