[Function] In the above configuration, even if the telephone is left in the calculation mode, it returns to the telephone mode after a certain period of time, so that it can perform its original function as a telephone.

[Example] Hereinafter, an example according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of one practical example according to the present invention, in which 1 is a hook switch that is closed when the handset 4 is in an off-hook state to form a DC loop in the connection line, 2 is a dialing circuit, and 3 is a hook switch. Reference numeral 4 denotes a known handset, which performs impedance matching with the line and controls communication with the handset 4.

A telephone number signal generating circuit 8 and a telephone call circuit 3 are connected to the hook switch 1 via a dialing circuit 2, and a handset 4 is connected to the telephone call circuit 3. Further, 5 is a bell circuit which generates a ringing tone in response to a called signal from the line.

6 is a telephone line connected to the public telephone network; 7 is a memory consisting of a memory area used for calculator calculations, a memory area for one-touch dialing, etc., which stores the calculation progress and processing results in the control circuit 9; , 8 is a telephone number signal generation circuit that outputs a telephone number signal corresponding to the input dial key, and 9 is a telephone number signal generating circuit that outputs a telephone number signal corresponding to an input dial key. 9a is a ROM that stores parameters used in this embodiment in addition to the above-mentioned program; 10 is a control circuit that controls the operation; 10 is a ROM that stores parameters used in this embodiment; 11 is a dial key for inputting telephone numbers, calculation information, etc., and consists of a numeric keypad, # key, and input key. . Reference numeral 12 represents a function key such as a one-touch key, and reference numeral 13 represents a display device for displaying various processing data.

The functions of the dial keys 11 and function keys 12 differ between the telephone mode and the calculator mode, and the switching thereof is also performed by the control circuit 9.

Next, the control operation of this embodiment having the above configuration will be explained with reference to the flowchart of FIG.

FIG. 2 is mainly used to explain the operation mode of this embodiment, focusing on the control procedure for switching between telephone mode and calculator mode, and the operation control in other normal telephone mode and calculator mode is Since this is well known, detailed explanation will be omitted.

The following procedure is initiated in a reset state, such as when the phone is powered on.

First, in a loop of steps S1 and S2, a known telephone function is executed until the calculator mode switching key is pressed.

This telephone function performs the following processing.

That is, when a called signal is received from the line 6, a ringing tone is sounded from the bell circuit 5, and when the handset 4 is turned off-hook in response, a DC loop is formed in the line 6 by the action of the hook switch 1, and the call is made. When the line 6 becomes available, the call ends, and the user goes on-hook, the DC loop to the line 6 is released and the line is restored.

On the other hand, when a call request is made with the handset off-hook, a DC loop is formed in the line due to the off-hook, and a dial tone is sent from the telephone line. After confirming the dial tone, the user inputs the telephone number of the called party using the dial key 11, and when the other party answers, the call is made, and when the call is finished, the handset 4 is put on the hook to release the line and the line is restored.

If the calculator mode switching key 10 is pressed while operating as a telephone in this manner, the loop is exited from the determination in step S2 and the process proceeds to step S3, where a timer built in the control circuit 9 is started for a predetermined period of time. . This timer time is a time for automatically switching to the telephone operation mode when there is no gate input for this time during the subsequent execution of the calculator mode.

When the timer is started, a calculator function processing loop of steps 84 to S8 is entered. In this loop, a known calculator function is performed. That is, in step S4 it is determined whether or not a key used in the calculator has been pressed, and if any key has been pressed, the calculator processes corresponding to the key input is performed in step S5, and the timer is reset in step S6. do. Then, in step S7, it is checked whether the calculator mode switching key 10 has been input, and if not, it is checked in step S8 whether or not the timer circuit has timed out. If the timeout has not occurred, the process returns to step S4, and if the timeout has occurred, the process returns to step S1, the operating mode as a telephone. Note that if there is no key input in step S4, step S7
will proceed to. At this time, the execution status processing progress in the calculator mode is sequentially displayed on the display device 13.

The conditions for exiting the loop from step 84 to step S8 are as follows:
This is the case when the calculator mode switching key 10 is pressed or a certain period of time passes without pressing any keys used in the calculator.

According to the above steps, even if you forget to switch to phone remote while using calculator mode, if no key used for the calculator is pressed for a certain period of time, it will automatically return to phone mode. .

Further, although a multi-function telephone is used here, it is also possible to perform similar control on a dedicated telephone in a key telephone system.

Furthermore, the calculator mode switching key 10 may be an illuminated key to display the current operating mode, or this operating mode may be displayed on the display device 13.
