A first motor driving circuit 19 shapes the drive pulse pd+ and drives the first motor 20.

A second motor drive circuit 21 shapes the drive pulse pd2 and drives the second motor 22.

The first motor 20 drives the hour and minute hands 2.3, and the second motor 22 drives the second hand 4.

Next, the operation of the analog electronic timepiece with roulette having the above configuration will be explained.

First, to explain the watch mode, as shown in Figure 2, in the watch mode, the hour and minute hands 2 and 6, and the second hand 4 are operating normally, and the crown 5, mode switch button 6, and start/stop button 7 are all operating normally. It is in an unoperated state.

Therefore, as shown in Table 2, in this watch mode, all of the external switch group 10 81 to S4 are OFF, and all the signals from the switch input control circuit 11 are at L level. Since the correction switching circuit 12a has the 1-level crown 1-crop pull signal Sr input to the C terminal, it is in the B input side selection output state. Furthermore, since the L level signal is input to the C terminal of the switching circuit 16, the A input side is in the selected output state. That is, the 1/60 nz signal PIT+ is selectively outputted from the correction switching circuit 12a, and is supplied to the hour and minute hands 2 and B via the first motor drive circuit 19 and the first motor 20. An I Hz signal P8 is selectively outputted from the switching circuit 16 and is supplied to the second hand 4 via the hand position counter 18C1, the second motor movement circuit 21, and the second motor 22. □ Next, the time adjustment standby mode will be explained.

Time adjustment standby mode refers to the stages before and after correcting the time, when the crown 5 is pulled out one stroke and the hour and minute hands 2.3
And the second hand 4 is in a state where its movement is stopped.

Therefore, as shown in Table 2, in this mode, only 81 of the external switch group 10 is ON, and the switch input control circuit 11 outputs the switch signal Psw□. R
Since the switch signal P sw2 is input to the S terminal of the -8FF 12b, the ζ output outputs the L-level signal Sr. Since the L level signal is input to the C terminal of the correction switching circuit 12a, the correction switching circuit 12a selects and outputs the human power side signal. However, since no signal is input to the human power side, the hour and minute hands 2.6 do not move and remain at their original positions.

Furthermore, since the anime game 1-A2 is turned off, the second hand 4 does not move and remains at its original position.

Next, the time adjustment mode will be explained.

The time adjustment mode is a mode in which the time is adjusted following the time adjustment standby mode, and is a state in which the crown 5 is rotated with the crown 5 pulled out.

Therefore, as shown in Table 2, in this mode, 81 and 82 of the external switch group 10 (JN, S3 and 84 are OF
F, and the switch input control circuit 11 outputs the Swiss-Sochi signal P□1. Since the switch signal Psw+ is input to the A input of the correction switching circuit 12a, the switch signal Paw for correcting the time is transmitted to the hour and minute hands 2 via the first motor drive circuit 19 and the first motor 20. .6 is supplied. After the time adjustment is completed, the crown 5 is pushed in to change the mode from the time adjustment standby mode to the watch mode.

Therefore, as can be seen from Table 2, the external sweet tooth group 10
This is an operation of switching Sl from ON to OFF, and the switch input control circuit 11 also outputs the switch signal pHW3. At this time, the switch signal P8W is input to the R terminals of the second counter 18a and the hand position counter 18C, so that the second counter 18a and the hand position counter 1
The contents of 8C are cleared. Also, the R-3FF12b
Since the switch signal P m w 3 is also input to the R terminal, the C terminal outputs an H level crown 1-crotch pull signal. Since the correction switching circuit 12a receives an H level signal at the C terminal, it selects and outputs the signal on the B input side. At this time, the 1/60 Hz signal pm, which is the output of the frequency dividing circuit 9, is input to the B input side. or,
At the same time, the AND gate A2 is also turned ON, and passage of the IHz signal P8, which is the output of the frequency dividing circuit 9, is also permitted, and the mode returns to the clock mode.

Next, the roule/nod mode will be explained with reference to FIG.

The roulette standby mode refers to the stage before and after moving the roulette hand 4 in rapid forward motion, when the mode switching button 6 is pressed to O.
NL, the hour and minute hands 2 and 6 are moving, but the second hand 4 is not moving.

Therefore, as can be seen from Table 2, in this mode, only 83 of the external switch group 10 is ON, and the switch input control circuit 11 outputs the switch signal Psw4.

At this time, since the switch signal PIIW4 is input to the S terminal of the R-8FF 13a of the mode switching circuit 13, the Q output outputs the switching signal Sk at the H level. Since the signal switching circuit 16a receives an H level signal at the C terminal,
The signal on the B input side is selectively output. However, B
Since the AND gate A1 on the input side is OFF, nothing is supplied to the second motor of the needle position counter 18C1 and the drive circuit 21, and the roule/to hand 4 remains at its original position without performing fast forward movement. .

The roulette start operation is an operation of moving the roulette hand 4 in rapid forward motion following the roulette standby mode.
Turn on the start/stop button 7. Therefore, as can be seen from Table 2, in this operation, S4 is switched from (JFF to ON) while Sl, S2, and S4 of the external switch group 10 are OFF and 83 is ON. Switch signal P0 from input control circuit 11
6 is output. At this time, the roulette control circuit 14
The switch signal Paw,
is input, the Q output outputs an H level start command signal SI. This turns AND gate A1 ON.
L, since the fast-forward speed control circuit 17 selectively outputs the 64Hz fast-forward signal Pf, the signal switching circuit 16
A 64Hz fast-forward signal pt is output from the C terminal of. The 64Hz fast forward signal Pf is connected to the needle position counter 18C and the second
The signal is supplied to the motor drive circuit 21 and moves the roulette hand 4 in fast forward motion via the second motor 22.

Roulette Stov 7" 1121 When the roulette hand 4 is moving in fast forward motion at 64Hz, the start/stop button 7 is turned OFF"j6°.Therefore, as shown in Table 2, 84 of the external switch group 10 is turned off. This means that the switch input control circuit 11 outputs a switch signal P s W ? from ON to OFF. is output. At this time, the roulette control port! 14 R-3FF
Since the switch signal P1w7 is input to the Si element 14b, the Q output outputs the H level stop command signal Sst. The stop command signal 3st is input to the D terminal of the D-FF 15b of the random delay circuit 15, but is not immediately output from the C terminal, and is input to the φ terminal of the frequency dividing circuit 9. A random delay is applied until the fall of the Hz signal Ph occurs, and the stop signal SIP is output from the C terminal. The roulette needle 4 is 6
One round is made on the 0 scale, but if the random delay takes the maximum delay time of 8 seconds, the start/stop button 7 is pressed (JFF) and then the 138 scale (32X4+4
X2+I X2=138) will proceed. This is 8
This is a case where the 1z fast-forward signal pt2 is selectively output for 4 seconds, the 4 Hz fast-forward signal p f 3 is selectively output for 2 seconds, and the 111z signal P is selectively output for 2 seconds. In this way, in the roulette stop operation, a random delay is applied and at the same time, the roulette hand 4 stops while decreasing its speed. The strike signal Sap is pulsed by the pulse generator 15a, and the R-3FF 14
It is input to the R terminals of a and 14b and the R terminal of the D-FF 15b. As a result, the start command signal Sam output from the C terminal of the R-8FF 14a becomes L level, and the AND gate A1 is turned off. Further, since the input to the C terminal becomes L level, the fast-forward speed control circuit 17 selectively outputs the 6411z fast-forward signal Pt. Since the signal switching circuit 16 selectively outputs the B input side, the needle position counter 18c and the second motor drive circuit 21
Nothing is inputted to , and the roux/throat hand 4 changes from a fast forward movement state to a stopped state, and enters a roulette standby mode.

To convert from roulette standby mode to watch mode,
The mode switching button 6 may be turned off. When the watch mode returns, the roulette hand 4 will again play the role of the second hand 4.

Therefore, as can be seen from Table 2, in this operation, Sl, S2, and S4 of the external switch group 10 are switched from ON to OFF when 83 is (JFF and JN), and the switch... A switch signal P aws is output from the input control circuit 11 .

At this time, since the Swiss/Sochi signal Psws is input to the S terminal of the R-8FF 13b of the mode switching circuit 16, the Q output is the H level coincidence circuit control signal Sl.
Output. The minus number circuit control signal Si is input to the C terminal of the coincidence circuit 18b, and the minus number circuit 18b starts operating. Also, AND gate A via OR gate 01
1 is also (JN), and the 6411z fast-forward signal Pf is output from the Q terminal of the signal switching circuit 16 until the content of the hand position counter 18C matches the content of the second counter 18a.

For example, if the content of the second counter 18a is 58 and the content of the hand position counter 18C is 24, 34 64 fiz fast forward signals pr will be input. and,
When the contents of the second counter 18a and the hand position counter 18C match, a coincidence signal Pi is sent from the Q terminal of the minus number circuit 18b.
is output.

The coincidence signal P+ is applied to R-8FF1 of the mode switching circuit 16.
It is input to the R terminals of 3a and 13b, and the output of the Q terminal becomes L level. As a result, the signal switching circuit 16 enters the manual selection output state, the minus number circuit 18b stops operating, and the AND gate A1 turns OFF. The IHz signal P8 is input to the second counter 18a and the hand position counter 18C, respectively, and the second hand 4 moves every second via the second motor drive circuit 21 and second motor 22.

〔Effect of the invention〕
