In addition, if an incorrect number is entered while inputting a telephone number by operating the switch 32, the input switch 32 is turned on while the control operation display lamp provided corresponding to the control button switch yc is lit. Yes, it has the same effect as pressing the control button switch A/'C, and the microprocessor CPU of 22 cancels the digit of the last memorized digit, and also cancels the digit of the digit displayed on the dial number display DIS of 25. Perform control/processing actions to cancel the numbers. Thereafter, by operating the input switch 32 in the same manner as described above, the CPU 22 stores the number corresponding to the operation starting from the canceled digit, and displays the dial number display DI on the dial number display 25.
Display on S. Further, the CPU 22 outputs a reset signal when the periodic display of the operation indicator lamp reaches a certain number of times without any operation of the input switch 32 being executed, and the device automatically recovers and returns to normal. When the input switch 32 is turned on after the end of the call, the CPU 22 receives the input via the analog switch 33, restores the relay H via the buffer inverter 18b, and switches the contact h1 to the dial circuit Di of 20. , 19 are disconnected from the office line, and the telephone equipment is restored and returns to its normal state.

Next, the case where dialing is made using the speed dial will be explained based on FIGS. 2, 3, and 4.

32 input switches, when input is turned on, 22 microprocessor CPUs are connected via 33 analog switches.

A communication circuit of Tc Di -LS -LI L2 is formed. At this time, the operation display lamp changes from a blinking display to a lighting display. After the call is over, when the input switch 32 is turned on, the CPU 22 receives the input via the analog switch 33 and restores the relay H via the buffer impedance 18b. As a result.

Due to the contact, the dial circuit section Di of 20 and the telephone circuit section Tc of 19 are disconnected from the central office line 27, and the telephone apparatus is restored and returns to its normal state.

Another example is a block diagram in which the operation display LED 23 and the decoder DEC 24 are removed from the block diagram of FIG.

The program of the microprocessor CPU of 22 is changed, and the display digits displayed on the dial number 5 display DIS of 25 are changed through the display controller 5 CPU of 26. For each digit, H-+A→1→2→... →9→H-+A→1→・・・
・By periodically displaying the digits as shown in FIG. The corresponding number is set in the corresponding digit of the display DIS 25, and the two-period display moves to the next digit, so that the number of the next digit can be set by the same operation as described above. After the desired telephone number is set by this operation, the second digit is the code H corresponding to the 7-way hook button switch HK (in this example, the code for the hook button switch HK is set to A and the code for the H1 control button switch). During the display, by inputting an ON signal from the input switch 32 via the analog switch 33, a dial call can be made. The other operations are the same as those in the previous embodiment, so their explanation will be omitted. Furthermore, it is clear that if a dial assist function such as an exhalation switch is not added, it can be used as a normal telephone.

As explained above in detail, the present invention enables the dialing operation of a telephone device to be performed by inputting a signal from one input switch while the desired number is displayed while looking at the operation display, thereby controlling the number of buttons on the sear button keyboard KEY. Its feature is that it has the same effect as turning on a switch, allowing dialing to be done with a simple action, and has the effect of expanding its range of use to people who find it difficult to use conventional telephones. big.
