PURPOSE:To dial again a dial number stored in a memory by forming an auto- redial discrimination circuit part for separating a circuit forcedly for a previously determined period and operating a redial key arranged on a keying part. CONSTITUTION:When a dial number is keyed from a keying part 2, te dial number is written on a memory 1. The auto-redial discrimination circuit part 7 discriminates whether a circuit has been previously separated once or no to execute redialling, and if the circuit is separated only once, the redial key is depressed under the state to reset a read counter 6 and execute dialling. If the circuit is not separated, the circuit is separated only by the fixed period previously determined by a flash timer 8, so that the read counter 6 is reset similarly by depressing the redial key under said state. Under the condition, the dial No. written on the redial memory 1 is transmitted to a dialling part 3 and originated. |
