l”rF key 8゜M/P key 9. RESF, T key 10
is formed as a touch switch by a transparent electrode (not shown) provided on the front surface of the LCD. Note that an LED can also be used as the display element.

The control unit 20 is configured with a CPU as its center, executes 81 o'clock or counting by counting a certain time reference pulse, and also controls liquid crystal driving of each display unit. Furthermore, the control *++ 20 executes arithmetic processing of adding and subtracting count values based on the registered input mode, and output processing of sending out an output signal from the output terminal based on the registered output mode.

The memory 21 stores precented times or count values, registered function modes, and input/output modes, and the stored contents are retained by a backup power source (not shown) even when the power is turned off.

The numeric display unit driving circuit 22 drives each numeric display liquid crystal of the counter/timer numeric display unit 2 and the preset numeric display unit 3. Each number is displayed while being segment-selected by dynamic driving. The character display section driving circuit 23 includes a function display section 4. Input mode display section 5. Output mode display section 6, output status display section 7. The characters on the key operation display section 24 of each operation key and the character display liquid crystal are driven.

The numeric display unit drive circuit 22 introduces a drive signal from the control unit 2o, causes the counter/timer numeric display unit 2 to display the timer time or count value number, and causes the preset numeric display unit 3 to display the preset value. . The character display section drive circuit 23 introduces a drive signal from the control section 20 and displays the character in the registered function mode on the function display section 4.
, and the characters of the registered input/output mode are displayed on the input mode display section 5 and the output mode display section 6. Function display section 4. Input mode display section 5. The characters before and after registration on the output mode display section 6 are displayed by blinking the liquid crystal.

The characters are displayed by continuous lighting, and after registration, the characters to be displayed blinking are sequentially switched in response to a switching instruction signal from the control unit 20. Further, an output status signal from the control unit 20 is introduced to switch the display on the output status display unit 7. The display on the key operation display section 24 is normally turned off,
Based on the external input signal introduced from the external input terminal, the display section of each operation key is lit to indicate that the input of the lit key is valid. Mode enable signal (hereinafter referred to as M
/ It is called the E signal. ) is introduced, lights up MODE and WRITE, and presses M/P key 9 and WRITP,
Displays whether key 8 input is valid. Preset enable signal (hereinafter referred to as P/E Shinsaki).

P, "F" are lit to display the input effect of the RESE, E, T keys 10. Inputs from these operation keys are given to the control section 20.

As mentioned above, there are three types of input modes, A, B, and C, which are executed when the counter function of the counter/timer device operates, and the input mode is executed by registering any one of them. Each input mode corresponds to adding or subtracting the number of pulses of the counter pulse CPI based on the counter pulses CP1 and CF2 input from the external input terminals.

For example, input mode A subtracts the number of pulses of counter pulse CP1 when counter pulse CP2 is on, and subtracts the number of pulses of counter pulse CP1 when counter pulse C'P2 is off.
This is a command input mode for subtracting the number of PI pulses. It should be noted that when operating as a timer function, the input mode is not registered in the counter, and therefore, processing in the input mode is not executed.

As mentioned above, there are four types of output modes executed when the counter and timer functions operate: N, F, C, and R.
This is executed by registering one of these. Each output mode corresponds to what is output from the output terminal when the actual timer time or count value reaches a preset value. For example, output mode N is
When the timer time reaches the preset time, or when the count value reaches the preset value, the output from the output terminal is turned on, and when the reset signal is applied from the external input terminal. This is a mote whose output is turned off.

The troublesome mode registration process of the counter timer device configured as described above will be explained with reference to FIGS. 3 and 4.
