Abstract

PURPOSE:To make possible a re-calling process after the on-hook operation of a public telephone set user without reinserting a prepaid card(PC) by temporary stopping the PC from being returned for a period, holding the balance of the PC and performing the re-calling process when the off-hook operation is performed in the period, and returning the PC after the period. CONSTITUTION:If a telephone number is misdialed in calling operation or if re-caging operation is performed even after a current telephone call ends by using the PC which is already inserted into a PC control part 5, the user lowers a hook 8 momentarily and lowers the hook 8, and then a hook switch 6 is opened. Then a hook timing control part 9 detects the hooking. The control part immediately opens a line switch 2 and closes the switch 2 a previously set time later. At this time, the hook 8 is raised, so a circuit part 3 repeats normal calling operation even at the time of the re-calling operation. The control circuit 9, on the other hand, monitors the closure of the switch 6 and delays output to the control part 4 by a previously set period. The control part 9 once detecting the closure of the switch 6 in the set period does not perform the output to the control part 4 and allows the re-calling operation.

なる。For example, when a dial error is made during a call operation, or when it is desired to call again using the prepaid card inserted in the prepaid card control unit 5 even after the current call is finished, The user instantly lowers the hook 8 (lowers it and then immediately raises it) (hooking), and when the hook 8 is lowered, the hook switch 6 is opened. When the hook switch 6 is opened, hooking is detected by the hook timing control unit 9. The hook timing control unit 9 immediately opens the line switch 2 and closes the line switch 2 after a preset timing (for example, 0.5 seconds). At this time, since the hook 8 is in the raised state, the speech path circuit unit 3 repeats the normal calling operation even when the call is reissued.

許容する。On the other hand, the hook timing control section 9 monitors the closure of the hook switch 6 and at the same time waits for an output to the control section 4 for a preset period (for example, 1 second). When the hook timing control unit 9 detects that the hook switch 6 is closed during this setting period, the hook timing control unit 9 does not output to the control unit 4 and calls again while holding the prepaid card already inserted and the remaining prepaid card information. Allow the operation.
