The locking pawl (8) of the locking plate Uυ, which is integral with the locking pawl (8), is rotatable about the fulcrum shaft (9) and is biased back to the locking position by the return spring QO+. is engaged and locked, and the standby state is maintained.

Next, in the above standby state, return the transmit/receive switch button (1) to the operating position with your finger and push it down against the spring (4). The standby button (2) is unlocked by rotating against the spring (1ω).Then, the standby button (2) is returned to the non-operating position by the return spring (5), and the standby switch (forced At the same time, the transmission/reception switch button (1
) and the lever (13) integrated with the transmit/receive switch 0.
The transmitter is configured so that the operated element (14a) is pushed against a built-in spring to switch to the transmitting state. Note that the transmission/reception changeover switch (f4) is normally held in the reception state, and can be switched to the transmission state only when its operated element (14a) is pressed.

According to such a conventional example, it is convenient to be able to automatically cancel the standby state by simply pressing the transmit/receive switch button (1) in the standby state. There was a major defect that was likely to occur.

That is, in the receiving state, a noise called "Zah" is heard, but in the standby state, the noise disappears. Then, when a transmission signal is received from the other party in the standby state,
A beeping sound will be heard to notify you of this.

When I cancel the standby mode, the buzzer sound disappears, but when I heard the buzzer sound in the standby mode, I reflexively pressed the transmission/reception switch button (1) to cancel the standby mode. At that time, there are many cases where I have to put pressure on my fingertips and wait for a while while pressing the transmission/reception switch button (1).

However, in the conventional example mentioned above, when you press the transmit/receive switch button (1) in the standby state, the system immediately switches to the transmitting state, so the other party may be talking while in the transmitting state. Despite the fact that there is no communication, the system also enters the transmitting state.C1 There was a defect in which the beginning of the message being sent by the other party was easily missed.

OBJECTS OF THE INVENTION The present invention seeks to provide a transmitting/receiving device capable of correcting the above-mentioned defects.

Summary of the Invention The present invention comprises a control device for a transmitting/receiving switch so that when the transmitting/receiving switching button is operated to an operating position in a standby state, the standby button is unlocked and a receiving state is obtained. If you are in standby mode and receive a transmission signal from the other party and hear a beeping sound, you can immediately hear the other party's transmission from the moment you press the transmit/receive switch button to cancel standby mode. It is designed so that it can be received and the beginning of what the other party is saying will not be missed.
