FIG. 3 shows a circuit configuration of the present embodiment. That is, the present embodiment has a configuration in which another circuit unit is connected to the CPU 50 as a center. CPU 50
Is a circuit that creates data by processing and processing the transmitted data, sends signals to each circuit unit, and controls them. The oscillation circuit 51 is a circuit that constantly sends out a signal of a constant frequency. The frequency dividing circuit 52 divides the signal from the oscillating circuit 51 to obtain a 100 Hz signal and a 1 Hz signal, and sends the former to a stopwatch control circuit 57 and the latter to a total clock circuit 56 and a subtraction timer control circuit 59. Department. The clock counter circuit 56 outputs a 1-minute signal (1P
/ M) to the motor drive circuit 53. The motor driving circuit 53 is a circuit that obtains the 1P / M signal from the frequency dividing circuit 52 and drives the pointer driving step motor 19. The pointer driving step motor 19 is driven by the motor driving circuit 53 to rotate. Then, a rotational force is applied to the hands 55 via the wheel train mechanism 54 to move the hands 55. The clock counting circuit 56 counts the 1 Hz signal from the frequency dividing circuit 52, obtains the current time T and the date D of the current day, and outputs these to C
This is a circuit for sending to the PU 50. Subtraction timer control circuit 5
Reference numeral 9 denotes a circuit for receiving a signal from the CPU 50 and sending out a 1 Hz signal from the frequency dividing circuit 52 to the subtraction timer counting circuit 60. The subtraction timer counting circuit 60 sets the time sent from the CPU 50, Each time the 1-Hz signal is sent from the control circuit 59, the set time is shortened by one second and the shortened remaining time is sent to the CPU 50. The stopwatch control circuit 57 is a circuit that receives a signal from the CPU 50 and sends out a 100 Hz signal from the frequency dividing circuit 52 to the stopwatch counting circuit 58. The stopwatch counting circuit 58 counts the transmitted 100 Hz signal. This is a circuit that measures the elapsed time and sends it to the CPU 50. The RAM 61 is a circuit controlled by the CPU 50 to store data from the CPU 50 and to send the stored data to the CPU 50. The RAM
The mode register N in 61 is a register for designating a mode. When the value is 0, the display window 7w is closed with the shutter plate 8 and the normal mode for displaying the current time only with the hour hand 4 and the minute hand 5 is designated. In the case of 1, the display window 7w is fully opened and the time mode for displaying the current time T and the date D from the clock circuit 56 is specified in the liquid crystal display device 10, and in the case of 2, the liquid crystal display device 10 The other function mode for displaying various data is designated here by exposing only the upper part of. The mode register M is a register for selecting and specifying an alarm time display mode, a stopwatch mode, and a timer mode belonging to the other function mode. When the set value is 0, the alarm time display mode is set. At 2, specify the timer mode. The position register SR is a register for storing a step value indicating the rotational position of the shutter plate 8. The step value is stored in the liquid crystal display device 10 when the first mask portion 8 a of the shutter plate 8 comes on the liquid crystal display device 10. Is 0 when the entire surface of the shutter plate 8 is covered, and thereafter, increases by 1 each time the shutter plate 8 rotates leftward by 3 ° (that is, 1 turn per rotation).
On the other hand, each time it rotates rightward by 3 °, it decreases by one. The alarm time register ALT is a register for storing the alarm time when the alarm time is input. The switch unit 62 is a circuit unit that includes the above-described push button switches SN and sends a corresponding switch input signal to the CPU 50 when any of them is operated. The motor drive circuit 62 is a circuit that receives the signal from the CPU 50 and drives the shutter plate rotation step motor 30 to rotate by a predetermined angle each time.
The rotation of the step motor 30 for rotating the shutter plate is applied to the shutter plate 8 via the wheel train mechanism 64, and rotates the shutter plate 8. In this case, every time the signal L or R is sent from the CPU 50, the shutter plate 8 is set at 3 ° (that is, 360 ° / 120 steps).

Operation Next, the operation of the embodiment constructed as described above will be described.

FIG. 4 is a general flowchart showing an outline of the operation of the present embodiment. That is, step S1
Then, it is checked whether or not there is a switch input, and when there is a switch input, the corresponding switch processing (step S
After the execution of 2), if there is no switch input, the process directly proceeds to the alarm process of step S3. In the alarm processing, it is checked whether or not the alarm time stored in the alarm time register ALT has been reached based on the date D from the clock counting circuit 56 and the current time T. When the alarm time has been reached, the shutter plate 8 is rotated. The liquid crystal display device 10 is fully opened, and the alarm time is blinked on the liquid crystal display device 10. Next, in step S4, a value other than 0 is set in the mode register N, and it is determined whether the mode is a mode other than the normal mode. When the mode is other than the normal mode, a display for displaying various data on the liquid crystal display device 10 is performed. After executing the process (step S5) and in the normal mode, the process directly returns to step S1, and thereafter, the same operation is repeated. FIG. 5 is a flowchart showing the switch process (step S2) in detail, and FIG. 6 is a flowchart showing the display process (step S5) in detail. Hereinafter, operations in various states will be described.

For example, now, 0 is set in the mode register N, and in the normal mode, 0 is set in the position register SR, and as shown in FIG. It is assumed that the shutter plate 8 is closed by the first mask portion 8a. In this case, unless there is a switch operation, the fact is confirmed in step S1 and the above-described alarm processing (step S3) is performed. Then, in step S4, 0 is set in the mode register N.
That is, the operation of determining that the mode is the normal mode and returning to step S1 is repeated.

In order to switch the mode from the normal mode to the time mode, the push button switch SN is operated. At this time, upon receiving the operation, the process proceeds from step S1 to step S2, that is, the switch processing of FIG. SN operation is detected, and the value of the mode register N is set to 1
Then, the time mode is set to a value that is larger by 1, that is, 1 (step S11). Next, it is determined that the value of the mode register N has not yet exceeded 2 (step S1).
2). It is determined that the value of the mode register N is 1 (step S14). The process proceeds to step S20 and subsequent steps. Then, a signal L is given to the motor driving circuit 63 to rotate the shutter plate rotating step motor 30 by a predetermined angle to rotate the shutter plate 8 counterclockwise by one step, that is, forward rotation (step S20), and to store the rotation. The operation of setting the value of the position register SR by 1 (step S21) and checking whether the value of the position register SR has reached 30 (step S22) is called the position register S
Repeat until the value of R reaches 30. When the value of the position register SR reaches 30 and the shutter plate 8 rotates 90 ° to the left from the previous normal mode and the entire surface of the liquid crystal display device 10 is exposed from the display window 7w, it is stepped. The detection is detected in S22 and the process proceeds to step S23, in which the display start signal DS is sent to the display drive circuit 65, and the liquid crystal display device 10
Is set to a displayable state. Then, step S3 in FIG.
After S4, the process proceeds to step S5, that is, the display processing of FIG. 6, and it is determined that the value of the mode register N is 1 and the time mode is set (step S60).
The current time T and date D from 6 are displayed on the upper and lower rows of the liquid crystal display device 10, and the process returns to step S1 in FIG. Thus, for example, at 10:35:26 on October 15, the display of the liquid crystal display device 10 is shown in FIG.
It becomes as shown in.

In order to switch the mode from the time mode to the other function mode, the push button switch SN is operated. At this time, the operation is performed in the same manner as in step S1 in FIG.
0 is detected, the value of the mode register N is set to a value larger by 1, that is, 2, and the process proceeds to step S14 via step S12, where it is determined that the value of the mode register N is 2, and the steps after step S25 are performed. move on. And
The signal L is sent to the motor drive circuit 63 to rotate the stepper motor 30 for rotating the shutter plate, that is, the shutter plate 8 forward by one step (step S25), and to increase the value of the position register SR by one to store the rotation (step S25). (Step S26), it is determined that the step value of the position register SR is not a value obtained by adding 65 to the value obtained by multiplying the value of the mode register M at that time by 10 (Step S2).
7) Return to step S25. Note that the value obtained by adding 65 to the value obtained by multiplying the value of the mode register M by 10 is, when the value of the mode register M is 0 and the alarm time display mode is set,
At this time, the shutter plate 8 is rotated left by 195 ° (that is, 65 × 3 °) from the normal mode, that is, the alarm time display mode indicator 45 of the second mask portion 8c is positioned at the center of the display window 7w. When the value of the mode register M is 1 and the stopwatch mode is set to 75, the shutter plate 8 is rotated left by 225 ° (ie, 75 × 3 °) from the normal mode, that is, The stopwatch mode indicator 46 of the second mask section 8c is displayed below the center of the display window 7w, and when the value of the mode register M is in the two-timer mode, the value is 85. At this time, the shutter plate 8 is in the normal mode. A position rotated leftward by 255 ° (ie, 85 × 3 °) from the time, that is, the timer mode display 47 of the second mask section 8c is displayed on the display window. It is displayed in the center below the 7w. As described above, after returning to step S25,
Similarly, the shutter plate 8 is rotated counterclockwise by one step to increase the number of steps of the position register SR by one, and the number of steps of the position register SR is set to the above value specified by the value of the mode register M at that time. The operation of checking whether the condition has been reached is repeated (steps S25 to S27). When the number of steps in the position register SR reaches the value specified by the mode register M, this is detected in step S27, and the display processing is performed through steps S3 and S4 in FIG. ), And then to step S62 via step S60. Step S62
In this case, the value of the mode register M is 0, 1, or 2, that is, whether the alarm time display mode, the stopwatch mode, or the timer mode of the other function modes is designated is specified. Various data are displayed on the liquid crystal display device 10 according to the mode (steps S63 to S65). That is, when the value of the mode register M is 0 and the alarm time display mode is designated,
The alarm time of the alarm time register ALT is displayed (step S63). When the value of the mode register M is 1 and the stopwatch mode is designated, the stopwatch measurement time STT from the stopwatch counting circuit 58 is displayed (step S63). Step S64), mode register M
Is 2 and the timer mode is designated, the timer remaining time TRT from the subtraction timer counting circuit 60 is displayed (step S65). In this case, each of the data is displayed on a relatively large seven-segment display for displaying time on the upper side of the liquid crystal display device 10, and a relatively small seven-segment display for displaying date below the liquid crystal display device 10. At this time, the alarm time display mode display 45, the stopwatch mode display 46, and the timer mode display 47 printed and displayed on the first mask 8c are covered with the first mask 8c as described above. Is located at the center of the display window 7w according to the corresponding mode, so that it is possible to easily recognize which mode the data being displayed relates to. For example, assuming that 1 is set in the mode register M and the stopwatch mode is set, the liquid crystal display device 10 as shown in FIG.
Above the stopwatch measurement time STT (in this case,
(Because it is not yet measured, it is 0 hour 0 minute 0 second) is displayed, and below the stop watch mode display body 46 of the first mask portion 8c of the shutter plate 8 is shown.

As described above, the other function mode is set, and if any of the alarm time display mode, the stopwatch mode, and the timer mode in the other function mode is set, another state in the other function mode is changed from the state. To switch to the mode, the push button switch SM is operated. For example, FIG.
When the pushbutton switch SM is operated as described above to set the timer mode in the state shown in FIG. 5A, that is, the stopwatch mode, the process proceeds to step S30 in FIG.
In step S31, the value of the mode register M is increased by 1 to set the timer mode to 2 (step S31), and it is determined that the value of the mode register M does not exceed 2 (step S32). It is determined that the value is 2, and the process proceeds to step S43 and subsequent steps. Next, in steps S43 to S45, the position register S
The signal L is sent to the motor drive circuit 63 until the step value of R reaches 85, that is, until the timer mode display 47 of the first mask section 8c is positioned at the center of the display window 7w. The step motor 30, that is, the shutter plate 8 is rotated leftward by one step, and the operation of increasing the step value of the position register SR by one is repeated. Then, when the step value of the position register SR becomes 85 and the timer mode display 47 reaches the center of the display window 7w, the display processing is performed from step S45 through steps S3 and S4 in FIG. In step S62 in FIG. 6), the value of the mode register M is already 2
Confirms that the timer mode is set, and displays the remaining timer time TRT from the subtraction timer counting circuit 60 in step S65 (however, in this case, 0 minutes is displayed because the timer time is not set). . Thus, the present embodiment functions as a subtraction timer, but when setting the timer time to be measured, the push button switch SA
Is operated. At this time, the timer time is decremented in step S50 of FIG.
Is performed. The start and end of the measurement are performed by operating the push button switch SB. In this case also, the subtraction timer control circuit 59 is used in step S50.
When the remaining time TRT of the timer reaches 60 minutes after the start of the measurement, the liquid crystal display device 1
0 is displayed as shown in FIG. 8 (b).

To switch the mode from the timer mode to the alarm time display mode in the other function mode,
Further, the push button switch SM is operated. At this time, the operation is detected in step S30, the value of the mode register M is increased by 1 to 3 (step S31), and it is determined that the value of the mode register M has already exceeded 2 (step S3).
2) Then, the value of the mode register M is returned to 0 (step S33), and it is determined that the mode register M is already in the alarm time display mode by setting the value of the mode register M to 0 (step S34). Processing proceeds to In steps S35 to S37, the signal is sent to the motor drive circuit 63 until the step value of the position register SR reaches 65, that is, until the alarm time display mode indicator 45 of the first mask section 8c is positioned at the center of the display window 7w. When R is sent, the shutter plate rotating step motor 30, that is, the shutter plate 8 is rotated in the reverse direction by one step, that is, clockwise to repeat the operation of reducing the value of the position register SR by one. When the step value of the position register SR becomes 65 and the alarm time display mode display 45 is positioned at the center of the display window 7w, the steps S3 and S4 of FIG. 4 and the steps S60 and S62 of FIG. Then, the process proceeds to step S63, in which the alarm time set in the alarm time register ALT is displayed on the liquid crystal display device 10. Also in this case, as described above, since the alarm time display mode indicator 45 is located at the center of the display window 7w, it is easily understood that the data being displayed is the alarm time.

Further, to switch from the alarm time display mode to the stopwatch mode, the push button switch SM is operated. At this time, the operation is detected in step S30, the value of the mode register M is set to 1 which is larger by 1 and the value of the mode register M is already set to 1 in step S34 via step S32, and the stopwatch mode is set. Then, the process proceeds to step S40 and subsequent steps. In steps S40 to S42, the signal L is sent to the motor drive circuit 63 until the step value of the position register SR reaches 75, and the shutter plate rotating step motor 30, that is, the shutter plate 8 is rotated leftward by one step (forward rotation).
Then, the operation of increasing the step value of the position register SR by one is repeated. When the step value of the position register SR becomes 75 and the stopwatch mode display 46 of the second mask section 8c is located at the center of the display window 7w, the processing proceeds from step S42 to step S of FIG.
3, S4, the process proceeds to step S64 via steps S60 and S62 in FIG. 6, and the stopwatch measurement time STT from the stopwatch counting circuit 58 is displayed on the liquid crystal display device 10 (see FIG. 8A, in this case, Since the measurement is not started, the stopwatch measurement time STT is 0 hour, 0 minute, 0 second, which is displayed). To start or stop measurement as a stopwatch, the push-button switch SA is operated. In this case, however, step S in FIG.
At 50, the process related to the start or stop is executed.

To return from the other function mode such as the stopwatch mode to the normal mode, the push button switch SN is operated. At this time, the operation is detected in step S10 in FIG. 5, the value of the mode register N is set to 3 which is larger by 1 (step S11), and the mode register N
Is determined to have already exceeded 2 (step S1).
2) Then, the value of the mode register N is returned to 0, and the normal mode is set. Thereafter, it is determined that the value of the mode register N is 0 and the normal mode is set (step S14), and the process proceeds to step 15 and subsequent steps. In steps S15 to S17, the step value of the position register SR becomes 120 and the entire surface of the liquid crystal display device 10 is
The signal L is sent to the motor drive circuit 63 to rotate the shutter plate rotating step motor 30, that is, the shutter plate 8 by one step counterclockwise (forward rotation) until it is covered by the first mask portion 8 a. Is repeated by increasing the step value of the step by one. When the step value of the position register SR reaches 120 and the liquid crystal display device 10 is covered with the first mask section 8a and becomes as shown in FIG. 7A, the process proceeds from step S17 to step S18, where the position register SR is reset. After that, the display stop signal DE is sent to the display drive circuit 65, and the display operation of the liquid crystal display device 10 is stopped. After the above operation, the process returns to step S1 via steps S3 and S4 in FIG. 4, and thereafter, the operation in the normal mode is repeated. The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the present invention.
