Title: Telephone set
Inventor: NANJO RYUICHI
IPC: H04M1/27
Filed: 1990-01-24
Abstract: PURPOSE:To detect whether wrong dialing number or mis-dialing depending whether or not an error display is implemented by turning on a comparator switch and redialing a number when wrong dialing is executed. CONSTITUTION:In the case of wrong dial, a switch 4 is hooked off to activate a comparator switch 9 and a telephone number is dialed again by using a dial key 8. The number is detected by a detection means 14b and stored in a buffer 13 via an input output means 14g. A comparison discrimination circuit 12 compares a telephone number stored in a dial memory 11 with a telephone number in the buffer 13 and the result of discrimination is received by a control means 14h via a discrimination detection means 14f. As the result of comparison discrimination, when the telephone number is same, no dialing is sent but error is displayed and when the telephone number is different, it is discriminated as that an erroneous dialing exists and the telephone number stored in the buffer 13 is read via the means 14g. Then the number is stored in the memory 11 and it is read to drive a pulse circuit 5 via the output means 14a and the pulse is outputted to a telephone line.
