[Background of the Invention]

In recent years, there is known an electronic wristwatch in which a rotating bezel is provided around the upper surface of a timepiece case and the time is corrected by rotating the rotating bezel. In this case, a switch that turns on and off according to the rotation of the rotating bezel is provided, the speed of the rotating bezel is detected by obtaining the time interval (off time) between the previous ON and the current ON, and according to this rotating speed. The amount of correction by turning on the switch once is controlled.

Here, it is necessary to correct only a small amount such as +1 minute, and when the rotary bezel is rotated by one step, if the switch is stopped in the OFF state, the previous ON state (the last correction ON) to this time
Since the time interval until (off time) is long, it must be + regardless of the rotation speed when the rotating bezel is rotated one step.
It will be one minute feed. However, if the rotating bezel is stopped in the ON state, if the rotating bezel is rotated one step when the rotating bezel is rotated quickly, the off-time is short, so it may be unintentionally corrected for fast forward. .

[Structure of Example]

Hereinafter, the present invention will be specifically described based on an embodiment shown in the drawings. FIG. 2 is an external view of a digital display type electronic wrist watch. A display unit 2 for digitally displaying the time is provided in the center of the watch case 1.
A rotating bezel 3 is rotatably attached around the display unit 2 in the upper part of the. Further, below the rotary bezel 3 inside the watch case 1, a bezel switch unit 4 including two switches S _A and S _B that are turned on in accordance with the rotating operation of the rotary bezel 3 is provided. here,
The switches S _A , S _B are switches for advancing the contents of the minute digits when the time is adjusted, and the switches S _A , for advancing the contents of the minute digits in the positive direction when the rotating bezel 3 is rotated counterclockwise. Purasusuitsuchi also switch S _B is intended to function rotating bezel 3 as a minus Sui Tutsi for stepping the minute digits of the content in the negative direction when rotating in a clockwise direction, and for indicating such a switch function display On the front surface of the watch, "+" and "-" are printed according to the rotating direction of the rotating bezel 3. Also,
The side of the watch case 1 is provided with a push-button switch S ₁ that functions as a mode switching switch that switches various modes to a cycle, and a push-button switch S ₂ that functions as a correction digit selection switch in the correction mode. There is.

Next, the configuration and operation of the plus switch S _A and the minus switch S _B will be described with reference to FIGS. 3 (a), (b) and (c). The rotating bezel 3 is rotatably attached to the outer periphery of the upper part of the watch case 1 without coming out upward, and the rotating bezel 3 is attached to the watch case 1.
_A plus switch S _A and a minus switch S _B are arranged corresponding to the lower side of the switch. These switches S _A , S _B
Is turned on each time the rotating bezel 3 is rotated by one step.

That is, the switches S _A and S _B are composed of the push buttons 5 and 6, the leaf springs 7 and 8 that elastically push up the push buttons 5 and 6, and the electrodes 9 and 10 that come into contact with and separate from the leaf springs 7 and 8. It is configured. The push buttons 5 and 6 are arranged side by side via a partition wall 11 so as to be vertically movable. The upper ends of the push buttons 5 and 6 are formed in an arc shape, and the O-rings 12 and 13 are attached to the middle parts thereof, and the lower ends thereof. Stoppers 14 and 15 for locking the push buttons 5 and 6 so as not to come out upward are attached to the portions. The leaf springs 7 and 8 are arranged below the push buttons 5 and 6 to elastically push up the push buttons 5 and 6 and to bend and deform vertically as the push buttons 5 and 6 move up and down. It is supposed to do. Further, the electrodes 9 and 10 are formed on the circuit board 16 and the leaf springs 7 and 8 are formed.
Of the leaf springs 7 and 8 are in contact with each other so that they can come into contact with and separate from each other.

On the other hand, an operating member 17 having a circular cross section is arranged between the rotary bezel 3 and the switches S _A and S _B. The actuating member 17 is provided with an inverted trapezoidal cam projection 3 a formed on the lower surface of the rotating bezel 3 as the rotating bezel 3 rotates.
Pressed by 3b, ..., Push buttons 5, 6 and partition wall 11
Of the cam projections 3a, 3b ...
The lower end surfaces of the push buttons 5 and 6 push down either one of the push buttons 5 and 6.

Then, normally, as shown in FIG.
Above, the actuating member 17 is the cam projection 3 of the rotating bezel 3.
It is arranged in the recess between a and 3b, whereby the pushbuttons 5 and 6 of the switches S _A and S _B are pushed up by the leaf springs 7 and 8, and the leaf springs 7 and 8 are pushed to the electrodes 9 and 10. Is separated from and is in an off state.

In this state, when the rotating bezel 3 is rotated in the arrow X direction, that is, in the "minus" side, the cam protrusions 3a, 3b ... Formed on the rotating bezel 3 move in the circumferential direction, and the right inclined surface of the cam protrusion 3b moves. contact with the actuating member 17, thereby actuating member 17 rolls onto the push button 6 of the minus switch S _B.
Then, when the rotating bezel 3 further rotates in the direction of the arrow X, the operating member 17 is pushed down, and the push button 6 is pushed down against the elastic force of the leaf spring 8, as shown in FIG. The tip of 8 is brought into contact with the electrode 10 on the circuit board 16. Thus, the negative switch S _B will be turned on.

In addition, in such a state, the rotary bezel 3 is further attached with an arrow X.
When the cam projection 3b is rotated in the direction, the cam projection 3b moves in the arrow X direction from above the actuating member 17, so that the depression between the cam projection 3b and the next cam projection 3c is located above the actuating member 17. Then, as shown in FIG. 3 (c), the push button 6 is pushed up by the leaf spring 8 and the actuating member 17 is pushed up into the recess between the cam protrusions 3b and 3c. Thus, apart from the leaf spring 8 from the electrode 10, the negative switch S _B is turned off. When subsequently rotating the rotary bezel 3 in the arrow X direction, in turn, turns on again minus switch S _B as in the case of FIG. 3 described above (b).

Thus, the rotary bezel 3 arrow X direction, i.e., is rotated to the "minus" direction, the negative switch S _B by the operation member 17 will be sequentially turned on.

The rotating bezel 3 is moved in the direction of the arrow Y, that is, on the "plus side".
When rotated to, the plus switch S _A operates in the same manner as the minus switch S _B described above with the rotation of the rotating bezel 3.

Next, the circuit configuration of this electronic wristwatch will be described with reference to FIG. FIG. 1 is a block circuit diagram of an electronic wrist watch of a micro program control system. The reference clock signal of, for example, 32,768 Hz, which is constantly output from the oscillator circuit 21, is frequency-divided by the first frequency dividing circuit 22 to, for example, 256 Hz, and is supplied to the second frequency dividing circuit 23. Second frequency divider circuit 2
Reference numeral 3 is a binary counter, which outputs a signal a every 1/16 second and gives it to the controller 24. When the controller 24 receives the signal a, the controller 24 gives a timing command to the address control unit 25 via the control bus (CONTROL-BUS), whereby the address control unit 25 receives the ROM (read only memory) 2
A predetermined address of 6 is designated to start the timing processing program.

The high-frequency clock output from the first frequency dividing circuit 22 is given to the timing generator 27, and the timing generator 27 operates in response to this, outputting various timing pulses to operate each circuit. HALT (standby state) release signal b output from
Has been entered.

On the other hand, the input unit 28 is provided with the push button switches S ₁ and S ₂ , the plus switch S _A , and the minus switch S _B , and when these switches are turned on, the input unit 2
A key operation signal C is output from 8 and given to the controller 24. In this case, the controller 24 gives a key processing command to the address control unit 25 via the control bus, whereby the key processing program corresponding to the operation key of the ROM 26 is addressed and the key processing is started. The input operation of the input unit 28 is controlled according to the output of the controller 24, and the key code stored in the input buffer in the input unit 28 is read.

The ROM 26 stores a micro program that controls all the operations of this electronic timepiece, and stores micro instructions ADDR, D
O, NA and OP are output in parallel. Micro instruction AD
DR is input to a RAM (random access memory) 29 via an address bus (ADDRES-BUS), and the RAM 29
Is specified and is also input to the input unit 28 and the display unit 2 to control the input operation and the display operation.
Further, the micro instruction DO is input as a numerical code to the multiplexer 30 via the data bus (DATA-BUS). The multiplexer 30 includes the contents of the second frequency dividing circuit 23,
The key code from the input unit 28 and the output data from the RAM 29 are also input, and the number of operations and the number of operands are switched and output at various processing timings and given to the operation unit 31 and the temporary register 32. In this case, the data held in the temporary register 32 is given to the arithmetic unit 31 in synchronization with the output data of the multiplexer 30.

Translate 26 addresses. The data written in the RAM 29 is read at each processing timing,
In addition to being input to the multiplexer 30, it is also input to the display unit 2 and the buzzer drive circuit 33. Here, the buzzer drive circuit 3
The reference numeral 3 drives the buzzer to generate an alarm sound at the alarm time. The controller 24 decodes the micro instruction OP and outputs various control signals to control the operation of each circuit.

In addition, the 256 Hz signal output from the first frequency dividing circuit 22 is the bezel switch ON / OFF time counter 3
Counted at 4. The counter 34 counts the ON time or OFF time of the plastic switch S _A and the minus switch S _B that operate in accordance with the rotation operation of the rotary bezel 3, and the ON time or OFF time of 1/256 second to 1 second. The time can be counted.
The carry signal of the counter 34 is input to the overflow detection latch 35 as a set signal. The contents of the counter 34 and the latch 35 are read into the RAM 29 via the multiplexer 30, so that the counter 34 and the latch 35 are reset respectively.

The RAM 29 is constructed as shown in FIG. FIG. 4 shows the main configuration of the RAM 29. The RAM 29 has an overflow input buffer bezel switch in which the contents of the overflow detection latch 35 are stored in addition to the time storage section in which the time data obtained by the timekeeping process is stored. ON / OF in which the count value data of the ON / OFF time counter 34 is stored

[Operation of Example]

First, an outline of the entire operation will be described according to the general flow of FIG. That is, when the signal a is output from the second frequency dividing circuit 23, the time counting process is performed, and the input unit 28
When the key operation signal c is output from, the program is stopped until the request signals a and c for the timekeeping process or the key input process are output in order to branch to the key input process, and the standby state (HALT) is entered. (Step S ₁ ). Now, when the signal a or the signal c is input to the controller 24, the controller 24 outputs the HALT release signal b and supplies the HALT release signal b to the timing generator 27. In response to this, the standby state is released. Now, assuming that the key operation signal c is output from the input unit 28, the next step S ₂
To the plus switch S _A or the minus switch S which is operated in accordance with the rotating operation of the rotating bezel 3.
Whether it is _B or not is determined, but the operation switch is the plus switch S
_A, if any of the negative switch S _B, and proceeds to step S _3, the key input processing corresponding to the switches S _1, S _2, for example, after the mode switching processing, the correction digit selection process or the like is performed, step Return to S ₁ . Further, when the signal a is outputted from the second frequency divider 23, ROM 26 counting processing program is designated, counting subroutine is started (step S _4). In this time counting process, the contents of the second frequency dividing circuit 23 are written in a predetermined area of the RAM 29, and then the contents of the second frequency dividing circuit 23 are cleared. Then, the contents of the second frequency dividing circuit 23 written in the RAM 29 and the present time stored in the time storage unit in the RAM 29 are added, and as a result, if a carry occurs, the address of the ROM 26 is changed and the digit processing is performed. To be executed. As described above, each time the signal a is output, the above-described timing processing is executed, and as a result, the current time data in the time storage unit in the RAM 29 is updated. Then, when the timekeeping process (step S ₄ ) as described above is executed, the next step S ₄
The process proceeds, after the display processing subroutine has been executed, a standby state returns to Step S _1.

Also, if in step S ₂ is positive switch S _A or negative switch S _B is determined to have been turned on, the key process to be described later in the next step S _6, i.e., pre-selected in the time correction mode _A correction process for correcting the content of the selected digit according to the plus switch S _A and the minus switch S _B is executed. And step S
Proceeds to _7, the same processing as step S ₁ described above is executed. Here, when the ON states of the sweeps S _A and S _B are detected again, that is, when it is detected that the switches S _A and S _B remain in the ON state and are stopped, the process returns to step S ₇ and waits. It becomes a state. Here, if there is a request for the time counting process again, the time counting process (step S ₈ ) and the display process (step S ₉ ) of the subroutine are executed, and then the step S
It returns to ₇ and becomes a standby state. Then, in this state, when the rotary bezel 3 is rotated and the switches S _A and S _B are turned off, this is detected in step S ₇ , and the next step is performed at the processing timing when there is no timing processing request. After proceeding to S ₁₀ and executing an ON time process described later, the process returns to step S ₁ .

FIG. 6 shows the specific contents of the key processing in step S ₆ of FIG. Now, in the time adjustment mode,
When correcting the contents of the selected digit selected in advance, the rotary bezel 3 is on the "plus side" when the current time is behind the exact time, and on the "minus side" when it is ahead.
If it is rotated in the direction, either the plus switch S _A or the minus switch S _B is turned on depending on the direction of rotation, and accordingly, the key processing of FIG. 6 is started. First, in step S ₁₁ , the bezel switch O
The count value data is read from the N / OFF time counter 34 and transferred to the ON / OFF time input buffer in the RAM 29. Now, the count value data of the ON / OFF time counter 34 corresponds to the OFF time of the switch S _A or S _B since it is the case where the switches S _A and S _B are turned on from the off state.
The OFF time is read into the OFF time input buffer. Then, in the next step S ₁₂ , the contents of the overflow detection latch 35 are read into the overflow input buffer in the RAM 29. In this case, since the OFF time before that is long at the beginning of the correction operation, ON / OFF
The carry output from the time counter 34 sets the overflow detection latch 35, and as a result, the set data is read into the overflow input buffer. When such read processing (steps S ₁₁ and S ₁₂ ) is completed, O
The contents of the N / OFF time counter 34 and the overflow detection latch 35 are reset (step S ₁₃ ,
S ₁₄ ). And while specifying whether the fast-forward modifications based on the contents of the fast forward flag register in the next step S ₁₅ RAM 29 is determined, first, the fast-forward state is not specified, the process proceeds to the next step S _16, overflow The contents of the input buffer are detected. In this case, since the OFF time has overflowed for more than 1 second at first as described above, the process proceeds to step S ₁₉ to execute the fast-forward flag clearing process, and then the process proceeds to step S ₂₀ to turn it on. It is checked whether the switch at is S _A or S _B. here,
If the switch S _A , the process proceeds to step S ₂₁ , and the correction process for +1 minute is performed, and if the switch S _B , the correction process for −1 minute is performed. Therefore, since the OFF time is long at the beginning of the correction, in this case, regardless of the rotation speed of the rotating bezel 3, the correction is always performed for +1 minute or -1 minute. Further, in this case, i.e., as shown in the time chart of Figure 8, switches S _A
Or the output time of one shot th square wave pulse output whenever the S _B is turned on, since the previous OFF time is long, is kept fast-forward state is released by the execution of step S ₁₉ There is.

Thus, when the switches S _A and S _B are turned on, the first 1
When the rotating bezel 3 is rotated in the same direction after the output of the pulse of the second pulse, the switches S _A and S _B are turned off, but when it is further rotated, it is turned on again to start the key processing of FIG. . In this case, assuming that the rotating bezel is rotated at a high speed, the OFF time counted by the ON / OFF time counter 34 becomes shorter according to the rotation speed, and as a result, the ON / OFF time counter 34 outputs No carry output is obtained, and the overflow detection latch 35 remains reset. Therefore, this time, after the step S ₁₁ to S ₁₆ has been executed, the process proceeds to step S _17,
ON / OFF time It is judged whether the content of the input buffer is 3/16 seconds or less, or when the rotating bezel 3 is rotated quickly now. Therefore, in this case, the OFF time is
Since the 3/16 seconds or less, the process proceeds to step S _18, fast forward flag is set. As a result, as shown in FIG.
The fast-forward state is set in synchronization with the rising edge of the second switch ON pulse. Then, depending on the type of the switches S _A and S _B , step S ₂₁ or S
As a result of executing step ₂₂ , even if the rotary bezel 3 is rotated at high speed to enter the fast-forward state, the correction is performed by +1 minute or -1 minute.

Then, similarly to the above, when the flow of FIG. 6 is entered in the state in which the rotary bezel 3 is being rotated at a high speed, steps S _{11 to} S ₁₅ are executed after step S _{11 to} step S ₁₅ since the state is the fast-forward state this time. _23, step S ₁₆ described above in S _24, S ₁₇
Processing similar to is executed. Where the overflow condition or
When the above 4/16 second is detected, then the process for releasing the fast forward state in step S ₁₉ is executed, the step S ₂₁
Or the process proceeds to S _22, not overflowing, yet not more than 3/16 seconds, on the switch or S _A or S _B is determined (step S _25). Now, assuming that the switch _{S A} is in operation, the ON / OFF time input buffer O
Steps S ₂₇ , S ₂₈ , and S _{29 of the} fast-forward processing for advancing the time according to the FF time are executed alternatively. Where 1
+16 minutes or less +30 minutes +2/16 seconds or less +
If it is 10 minutes, 3/16 seconds or less, +5 minutes of fast-forward operation is executed. Similarly, assuming that the switch S _B is in operation, a fast forward process to delay the time in accordance with the OFF time of the ON / OFF time input buffer is performed alternatively, not more than 1/16 sec -30 min, -10 min when 2/16 seconds or less, -5 minutes fast forward operation equal to or less than 3/16 seconds is performed (step S ₃₀ ~S _33). Therefore, when the rotary bezel 3 is rotated at a high speed for 3/16 seconds or less, the fast-forward operation is executed every time the switches S _A and S _B are turned on.

On the other hand, FIG. 7 shows the specific contents of the ON time processing in step S ₁₀ of FIG. When this ON time processing is started, first, the contents of the ON / OFF time counter 34 are transferred to the ON / OFF time input buffer (step S ₄₁ ). In this case, the ON / OFF time counter 34 counts the time interval from the previous OFF to the present OFF of the switch S _A or S _B , that is, the ON time, and this ON time is stored in the ON / OFF time input buffer. Will be read. Next, step S
By executing ₄₂ , the contents of the overflow detection latch 35 are transferred to the overflow input buffer. After that, the ON / OFF time counter 34 and the overflow detection latch 35 are reset (steps S ₄₃ and S ₄₄ ). Then, an overflow condition is detected based on the contents of the overflow input buffer,
It is determined whether the ON time has passed 1 second or more (step _S45 ). Now, fast forward flag in step S ₄₆ if the overflow condition is detected is released fast forward state is reset, also, without overflowing the next step S ₄₇
ON / OFF time ON time in the input buffer is 10
/ 16 seconds or more is determined. If it is 10/16 seconds or more, the process proceeds to step _S46 , and the fast-forward state is canceled. Thus, fast-forward state is canceled in step S ₄₆ in the case ON time as also was the fast-forward state in accordance with the rotational speed of the rotary bezel 3 is long (see FIG. 8).

Thus, in this state, when the case is rotated faster rotating bezel 3 into the flow of FIG. 6, steps S ₁₁ ~
Proceeds to S _15, but since the fast-forward state is released at this point, proceeds to step S _16. Now, since the rotated faster rotating bezel 3, OFF time becomes less 3/16 seconds, resulting in a re fast-forward state fast-forward flag is set (step S _18). However, at this point, the fast-forward flag is simply set and the fast-forward operation is not started, and the correction is +1 minute or -1 minute. Then, with the fast-forward flag set in this way,
When the flow of FIG. 6 is entered again, if the previous ON time is short, the fast-forward state is maintained as it is, and the fast-forward operation is started. Therefore, as shown in FIG.
It is necessary to make a small amount of correction, for example, +1 minute, after performing the fast-forward correction according to the rotation speed of, and when the rotating bezel 3 is temporarily stopped and the rotating bezel 3 is rotated by one step, the switch If is stopped in the off state, the off time is long, so the fast-forward state is canceled,
Moreover, if stopped in the ON state, the ON time is long, so that the fast-forward state is released, and as a result, correction such as +1 minute or -1 minute becomes possible.

The present invention is not limited to the above embodiments, and various modifications can be applied without departing from the present invention. For example, in the above embodiment, depending on the rotation speed of the rotating bezel 3, +5 minutes, +10 minutes, +30 or -5 minutes, -10 minutes,-
I tried to make a fast-forward correction of 30 minutes, but for example ± 10
Minute and ± 20 minutes of fast-forwarding may be used, and the time unit is not limited. In addition, the switches S _A , S of the rotating bezel 3
_{Although B} has a structure in which it is brought into contact with and separated from the electrodes 9 and 10, it may be constituted by an optical or magnetic means, and the rotation speed detecting means is arranged to count the number of input pulses generated within a predetermined time. May be. Furthermore, not only the rotating bezel,
The correction switch may be a crown or a slide switch.

Further, in the above-described embodiment, whether or not the fast-forward correction is performed is controlled according to the OFF time of the switch, but the present invention is not limited to the correction, and other function control may be performed.

〔The invention's effect〕

As described in detail above, according to the time adjustment device for an electronic timepiece of the present invention, not only the correction amount for each predetermined angle rotation can be changed according to the rotation speed of the rotation operation member, but also the correction can be performed efficiently. Since only a small amount is corrected even if the rotary operation member is rotated quickly, the operability when correcting a small amount is also good.
