In addition, the time information display means can perform either an analog display using a hand or a digital display using an LED or a liquid crystal panel.
When the mode switch 103 generates a timer mode output, the mode selection circuit 105 outputs a plurality of pieces of timer set time information such as 5 minutes, 10 minutes, and 15 minutes in the timer mode. The timer counting circuit 107 counts the elapsed time from the start of the timer when the timer switch 106 is turned on. The disk position storage circuit 108 stores an initial position of the disk, for example, an angle from the reference position or the number of steps.

FIG. 2 is a front view of a timepiece with a timer display showing one embodiment of the present invention. FIG. 3 is a plan view of the mode display section printed on the dial of the clock with the timer display. FIG. 4 is a plan view of a disk that rotates on the side of the dial of the timepiece with a timer display where the clock is located. The clock with a timer display according to one embodiment of the present invention has an hour hand 206 for displaying time information,
There is a minute hand 207. The dial 200 is provided with five display windows 201 to 205 for identifying the elapsed time of the timer. On the dial 200, a mode display unit 208 indicating a clock mode is printed. The mode display unit 208 is color-coded for each mode, and the time mode "TIME"
301 is white, timer 5 minute mode “5” 302 is blue,
Timer 10 minute mode “10” 303 is yellow, timer 15
The minute mode “15” 304 is red. Disk 40
On 0, color bands corresponding to the color classification of the mode display section are displayed along the circumference of the disk, such as white 401, blue 402, and yellow 40.
3, one-fourth of each circumference, such as red 404. These color bands indicate that the disk 400 is the dial 2
When the watch rotates on the side of the 00 clock body , the dial 200
Are printed at positions just visible from the display windows 201 to 205 provided in the display windows 201 to 205, and only one color is displayed on the display windows 201 to 205.
5 Make it possible to create a viewable state from all windows. The position where the border between the color bands of white 401 and blue 402 comes exactly in the middle of the third display window 203 is set as the initial position of the disk, and is stored in the disk position storage circuit 108. FIG. 5 is a schematic flowchart showing the operation procedure of the first embodiment of the present invention. When the mode of the clock is selected to the timer mode by the mode switch 103 and the output of the timer mode is generated, based on the initial position of the disk stored in the disk position storage circuit 108, the disk position counting circuit 109 Sets the initial position of the disk. (Step 501). It is determined whether the timer set time is 5 minutes (step 502). If the timer setting time is 5 minutes, a timer operation routine is performed when the timer setting time is 5 minutes. The operation of this routine is
It is determined whether or not the timer switch 106 is ON (step 505), and the timer does not start until the timer switch 106 is turned ON. When the timer switch 106 is turned on, the disk drive signal generation circuit 112 calls the disk drive pulse information for timer 5 minutes from the disk drive cycle storage circuit 110 (step 506). Disk drive signal generation circuit 11
2 adds the output information of the timer counting circuit 107 and the disc position counting circuit 109 to create a disc driving pulse for timer 5 minutes and outputs it to the disc motor (step 507). With this, the disk 114 is driven at a disk drive speed of 18 degrees for the timer for 5 minutes.
Rotate counterclockwise at e / min. It is determined whether or not the timer is stopped halfway (step 50).
8). If the timer switch 106 is operated to stop the timer halfway, the counting of the timer counting circuit 107 stops. The disc position counting circuit 109 counts each degree difference between the position where the disc 114 has stopped and the initial position. The disk drive signal generation circuit 112 generates a clockwise disk drive signal corresponding to this difference,
By the rotation of 3, the disk 114 returns to the initial position. If there is no stop, the disc 114 will be 18 for 5 consecutive minutes.
Rotate counterclockwise at degrees / min. It is determined whether five minutes have elapsed since the timer switch 106 was turned on and the time has been up (step 509).
If the time is up, a timer sound is output (step 510). The timer stops automatically and the disc returns to its initial position. If it is determined whether the timer set time is 5 minutes (step 502), and if the timer set time is not 5 minutes, then it is determined whether the timer set time is 10 minutes (step 503). If the timer set time is 10 minutes, a timer operation routine is performed when the timer set time is 10 minutes (steps 511 to 516). The difference between the operation of this routine and the case where the timer set time is 5 minutes is that the disk 114 is driven at the disk driving speed for the timer 10 minutes, that is, 9 degrees / min, and the condition for determining whether the time is up. Is the timer switch 1
The point is that it is determined on the condition that 10 minutes have passed since ON of 06. It is determined whether the timer setting time is 10 minutes (step 503).
If it is not 0 minutes, it is determined whether the timer set time is 15 minutes (step 504). If the timer setting time is 15 minutes, a timer operation routine is performed when the timer setting time is 15 minutes (steps 517 to 52).
2). The difference between the operation of this routine and the case where the timer set time is 5 minutes is that the disk 114 is driven at the disk drive speed for the timer 15 minutes, that is, 6 degrees / min.
The condition for determining whether or not the time is up is that determination is made based on whether or not 15 minutes have elapsed since the timer switch 106 was turned on. FIG. 6 is a schematic flowchart showing the operation procedure of the second embodiment of the present invention. The difference from the first embodiment is that, for example, when the timer set time is 5 minutes, 5 minutes after the timer switch 106 is turned on.
After the minutes have elapsed and the timer sound has been output (step 610), the timer does not stop and the operation returns to the timer 5-minute pulse output operation (step 607). This operation is the same for the case where the timer setting time is 10 minutes and 15 minutes. The difference from the case where the timer setting time is 5 minutes is that when the timer setting time is 10 minutes, the disk 114 is set to the circle for the timer 10 minutes. The plate driving speed, that is, the point of driving at 9 degrees / min, and the condition for determining whether the time is up are as follows.
The point is that the determination is made on the condition that 10 minutes have elapsed since the timer switch 106 was turned on. When the timer set time is 15 minutes, the point that the disk 114 is driven at the disk drive speed for timer 15 minutes, that is, 6 degrees / min, and the condition for determining whether the time is up are determined by the timer switch 106 being ON. The point is that the determination is made based on whether or not 15 minutes have passed since then. By the operation described above, counting of the elapsed time of the timer by the timer counting circuit 107 is continuously performed by the operation of the timer switch 106 on the way unless the stop is performed.
However, when the counting of the timer elapsed time operates continuously as described above, the time until the disk 114 returns to the initial position must be considered. Therefore, the disk position counting circuit 109 calculates the current position of the disk 114 and the disk 114
Is counted, and a signal for returning the disk 114 clockwise to the initial position until the difference becomes zero is output to the disk drive signal oscillation circuit 112. Then, when the mutual difference between the current position of the disk 114 and the position of the disk 114 to be displayed becomes zero, the disk 114 starts rotating counterclockwise. In the above embodiment, the timer setting time is 5 minutes, 10 minutes, and 15 minutes. However, the timer setting time can be arbitrarily set by design. In the operation of the above embodiment, the hour hand 260, the minute hand 207, and the disk 114 can both display the elapsed timer time. The hour hand 260 and the minute hand 207 can also display time information, and the disk 114 can display the timer elapsed time. When the time mode is changed to the time mode while the timer is operating, the hour hand 260
In addition, it can be said that the minute hand 207 displays the time information, and the disk 114 keeps displaying the timer elapsed time information as it is. FIG. 7 shows a case where the timer set time is 5 minutes, and FIG.
FIG. 9 shows the relationship between the timer elapsed time and the color seen from the display windows 201 to 205 in the case of minutes. FIG. 10 shows the elapsed time of the timer when the timer set time is 5 minutes and the change in the color seen from the display windows 201 to 205 of the clock. When the timer is started, the colors seen from the display windows 201 to 205 are all blue (step 1001). Within one minute from the start of the timer, the display window 201 changes from blue to white at a constant speed (step 1002). Between one minute and two minutes after the timer starts, the display window 202 in addition to the display window 201 changes from blue to white at a constant speed (step 1003). Between 2 minutes and 3 minutes after the timer starts, the display window 203 in addition to the display windows 201 and 202 changes from blue to white at a constant speed (step 1004). Between 3 minutes and 4 minutes after the timer is started, the display windows 204 are displayed in addition to the display windows 201, 202, and 203.
Changes from blue to white at a constant speed (step 100).
5). From 4 minutes to 5 minutes after the timer starts, all display windows change from blue to white at a constant speed (step 100).
6). The change in color seen from the display window described above is caused by driving a colored disk below the display window at a constant speed. The 10 minute timer is twice as long as the 5 minute timer,
The color of one window changes from yellow to blue at a constant speed. Fifteen
The minute timer changes the color of one window from red to yellow at a constant speed in three times the time of the five-minute timer. In the above embodiment, the same color as the color for identifying the timer elapsed time is provided on the mode display panel to make it easier to identify the timer set time and the timer elapsed time, but the identification means is not a color. Patterns and patterns can also be used. A first identification means for identifying an elapsed time provided on the disc;
The second identification means provided on the mode display plate does not need to be the same, and the timer setting time and the timer elapsed time correspond to similar colors or similar patterns or patterns. There are also ways to make it easier to identify Further, the number of windows is not limited to five and can be set arbitrarily. Also, the shape and position of the window can be set as needed.

As described above, the present invention relates to a timepiece with a timer, a disk position storage circuit for storing initial position information of a disk, a timer setting time information from a mode selection circuit, and a timer counting circuit. A disc position counting circuit that counts the position of the disc by inputting the output signal of
A disk drive cycle storage circuit for storing a disk drive cycle corresponding to a timer set time, a disk drive cycle calculation circuit for inputting timer set time information from a mode selection circuit and calculating a disk drive cycle, and a timer A circle that receives an output signal of a counting circuit, an output signal of a disk position counting circuit, and an output signal of a disk driving cycle storage circuit to generate an output signal to a driving unit that drives the disk. And a plate drive signal generation circuit, and thus have the following effects. When the colored plate rotates on the side of the clock face where the clock face is located, the color band seen from the window provided on the dial changes color, making it easy to check the timer elapsed time. A clock with a timer is obtained. Since the disk can be driven at a plurality of speeds, regardless of the timer setting time, it is possible to create a state in which the colors seen from all windows are displayed differently from the start time when the time is up. Therefore, a clock with a timer in which a plurality of timer times can be set is obtained. It has a disk that moves differently from the hands and numerals, and a watch with a different appearance and shape can be obtained.
