Next, the operation of the present embodiment that enables the display operation and operation in each of the above-mentioned display modes will be described with reference to FIGS. 4 to 6.

FIG. 4 is a general flow showing the flow of the overall operation of this embodiment.

The system is normally in the halt state shown in step a ₁ , and when the 16 Hz signal is output from the frequency dividing circuit 12 to the ROM address control unit 4, the microprogram stored in the ROM 4 is activated, and the step a ₂ Performs timing processing with. Details of the timekeeping process will be described later in detail. After the counting process based on the mode flag M in step a _3, the mode flag M
The display mode indicated by is displayed.

On the other hand, when the key operation signal from the key input unit 11 in step a ₁ is output to the ROM address controller 4, R in Step a ₄
A microprogram for key processing stored in the OM4 is activated, and key processing described in detail later is executed.

Next, the details of the timing processing of step a ₂ will be described with reference to the flowchart of FIG. In the figure, first, the basic time data read from the time register T in step c ₁ is input to the arithmetic circuit 7, the basic time data is added by 1/16 seconds by the arithmetic circuit 7, and the basic time data is again stored in the time register T. Written. In this way, the basic time is updated every 1/16 second. Then, as a result of updating the basic time in step c ₂ ,
It is determined whether 1 has been added to the minute digit, that is, whether the basic time has changed. If the change has occurred, then in step c ₃ , each bit b _n ( _n = ₀ in the mark display body storage area MD). ~
₂₉ ) whether or not there is a "1", and if there is a "1", in step c ₄ , the entire bit is shifted by 1 bit in the direction of the most significant bit b ₀ . Then, as a result of the bit shift, in step c ₅ , it is determined whether or not the most significant bit b ₀ is set to “1”,
"1" if it is set, the instruction data da from ROM3 in step c ₆ is output to the instruction decoder 6, the control signal from the instruction decoder 6 is outputted to the control gate C _5. As a result, the control gate C ₅ is opened, control data is input from the bus line to the sound output unit 13, and the sound output unit 13 outputs an alarm sound.

In this way, an alarm sound is generated at the train departure time.

After sounding alarms, the basic time data read out from the time register T in step c ₇ is input to the arithmetic circuit 7,
After 29 minutes have been added by the arithmetic circuit 7, the addition result (time after 29 minutes from the current time) is stored in the time register T '. Then, in step c ₈ , the time data storage area TD ₁
Some time data stored within performs time and there is a time if determination that matches that stored in the time register T ', the mark display body data stored in step c ₉ if there is time data matching “1” in least significant bit b ₂₉ in area MD
Set. Then, in step c ₁₀ , the mark display body D _n ( _n = ₀ to ₂₉ ) is lit according to the value of each bit b _n ( _n = ₀ to ₂₉ ) in the mark display body data storage area MD. That is, the mark display body D _n ( _n = ₀ to ₂₉ ) corresponding to the bit b _n ( _n = ₀ to ₂₉ ) whose bit value is “1” is turned on.

Thus, every 1 minute, the value of each bit b _n in the mark display data storage area MD is shifted by 1 bit in the direction of the most significant bit b ₀ in response to the change of the current time, and 29 minutes from the current time. If the later time data is stored in the time data storage area TD ₁ , the least significant bit b ₂₉ is set to "1". Therefore, if there is a train departing Tokyo Station 29 minutes after the current time, the mark display D ₂₉ lights up. Further, since the value of each bit b _n ( _n = ₀ to ₂₉ ) in the mark display data storage area MD is shifted bit by bit toward the most significant bit b ₀ , the mark display D _n ( _n = ₀ to ₂₉₎ ) Lighting position is 1 toward mark display D ₀
The unit is moved (see FIGS. 3B and 3C).

Then, if the key S ₁ to S ₄ is operated, shown in Figure 6 a detail of the key processing operation of the step a ₄ performed by the execution of the microprogram for the key process stored in ROM 3.
