Abstract

PURPOSE:To limit both the time and frequency of transmission of a radio transmission/reception device, by installing a transmission/reception switch signal circuit, a continuous transmission time detecting circuit and a repetitive transmission frequency detecting circuit each to the transmission/reception control terminal of a transmission/reception device. CONSTITUTION:When a continuous transmission is carried out by pushing consecutively the press switch 42, the output of the gate circuit 51 is set at the H level after at time that is decided by C2XR2. When the switch 42 is opened and closed repetitively in a short cycle, a pulse train is produced. And the input of the gate circuit 61 shows a staircase-shaped increment of voltage, and the output of the repetitive transmission frequency detecting circuit 6 is set at the H level after a prescribed time. When the continuous transmission detecting circuit 5 or the detecting circuit 6 is set at the H level, the outputs of the OR gate 71 and NOT gate 72 are set at the H and L levels each. Thus the operation of the switch 42 is prevented from being effective.
