動作を行う。In the mobile station 2, first, when the charging signal kd is transmitted from the control station 5 in a constant cycle during a call, as described above, each of the detectors 14 and 15 charges the charging signal f of 3,650 Hz.
a, the pilot signal f PL is detected, and the NAND circuit 1
6, the NAND signal of the two detection signals fa and f PLd is taken to generate the charging signal kp for the mobile station 2, and the normal charging operation is performed.

A start signal (“L” during communication) ST is applied to one terminal of the NOR circuit 18b, and the gate of the timing circuit 18c is opened when the other input is “L”. That is, the period of the charging storage pulse kp,
An output is obtained from the timing circuit 18c, and the billing signal creating circuit 18d outputs a regular billing pulse.

Alternatively, when the charging signal fa of 3,650 Hz does not come even after the time of the timing circuit 18c of the preset maximum charging period T has elapsed, as shown in FIGS. 2 (a) and 2 (b),
In other words, when at least one of the f PLd and ka is not detected, the output of the NAND circuit 16 is "H" during that period.
Therefore, "L" is input to the timing circuit 18c. However, the clear signal C which is the output of the NOR circuit 18b
L becomes “L”, the output is prohibited and a pulse is generated at the timer setting time (cycle) to generate the billing signal generating circuit 1.
Send to 8d, create and output charging pulse here,
A billing signal is supplied to the public telephone 1 by a circuit (not shown),
Thereafter, the billing signal generating circuit 18d supplies the billing signal kp to the public telephone 1 at a constant cycle. As a result, unlike the conventional case, the charging signal is not detected by the mobile station 2 and the call is not continued while the coins are not stored.
