PURPOSE:To attain the calling without minding a calling time with a caller by transmitting automatically the telephone number of the called person stored temporarily when the coin is thrown again within a fixed time after a ring-off is processed while the telephone number of the called person is temporarily stored in a memory part. CONSTITUTION:When the re-throwing of a coin is not detected after a reminding sound is sent, a CPU 9 temporarily cuts the direct current loop with a line 11 through a calling circuit SPC forcibly, and when during the coin re-throwing supervising time period from a clock circuit TIM 6, the detecting signal of the re-throwing of the coin is received from a coin detecting part DET 1 by the CPU 9, it is judged that the re-throwing of the coin of the caller is in time, a hook switch HS8 is automatically made into the off-hook condition and the direct current loop is formed again to the line 11 through an SPU 5. When a fixed time elapses after this, the dial data of the telephone number of the called person stored temporarily from an MEM 3 are read, and the dial data are converted to a dial signal sent from an OSC 4 through an SPC 5 to the line 11. Namely, the telephone number of the called person stored temporarily is automatically re-sent.
