Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a watch correction device.

(Prior art) There are a wide variety of conventional watch switches, but
As shown in Japanese Utility Model Publication No. 59-35827, there is only one type of function, such as conducting only at the position where the switch body is pressed, thereby generating one correction pulse.

(Problem that the invention aims to solve) However, in the conventional switch configuration, no matter how the switch is operated, there is only a function to generate one correction pulse, and for example, the correction pulse generated for each operation is It was not possible to change whether it was used for modification or for modifying additional functions.

(Means for Solving the Problems) The present invention provides a switch section by arranging a plurality of vertically arranged bar-like patterns on a substrate in an inclined manner, and connecting every other bar-like pattern. A circuit board divided into two sets, one set connected to the power supply side and the other set connected to the correction pulse input terminal of the watch, pressurized conductive rubber superimposed on this circuit board, and this pressurized Consisting of a plastic film overlaid on conductive rubber, by stroking the top surface of the switch from end to end, a bar-shaped pattern connected to the power supply side and a bar-shaped pattern connected to the correction pulse input terminal can be sequentially displayed. A correction pulse is generated by conducting with the oscilloscope. Moreover, the number of conductors between each pattern differs depending on the direction in which you touch the switch part with your finger.
By changing the direction of vibration, the number of pulses generated in a certain period of time changes. In the present invention, this time and the number of pulses are counted by a conduction time counter and a conduction frequency counter, and the occurrence timing detection circuit detects the timing of occurrence of the output signal. Detect. A switching gate circuit is provided which uses this detection signal as a switching signal to switch whether the correction pulse from the switch is supplied for correcting the current time or for correcting additional functions. Furthermore, after the modification is completed, that is, after a predetermined period of time after the switch ceases to be conductive, it has a modification completion signal generation circuit that returns the conduction time and conduction frequency counters and the occurrence timing detection circuit to their initial states.

(Embodiment) FIG. 1 is a diagram showing the arrangement of conductive patterns in a switch section of a watch correction device according to an embodiment of the present invention, and FIG. 2 is an explanatory sectional view of the switch section.

As shown in FIG. 2, the switch section 2 includes a pressurized conductive rubber 6 and a plastic film 8 placed on top of each other in this order on a circuit board 4.

When the plastic film 8 is pressed with a finger, the pressurized conductive rubber 6 comes into contact with the circuit board 4.
If two conductive patterns are arranged at this contact portion, these two patterns are electrically connected to each other.

On this circuit board 2, a conductive pattern as shown in FIG. 1 is arranged. Twenty bar-shaped conductive patterns are arranged on the circuit board 2 at an angle of 45 degrees. These 20 patterns are divided into 10 selected every other pattern and connected together, one pattern group 10A is connected to the H level side of the power supply, and the other pattern group 10B is shown in FIG. Connected to signal line B of the circuit to be connected.

FIG. 3 shows a block diagram of a timepiece according to the present invention, in which the reference signal generator 12 is replaced by the oscillator 1.
4 and a frequency dividing circuit 16, and this output signal is supplied to a current time counter 18 to count the time.

In this embodiment, the additional function circuit 20 is an alarm circuit, and includes an alarm counter 22 that stores an alarm time, a coincidence circuit 24 that detects coincidence between the alarm counter 22 and the current time counter 18,
It consists of an AND gate 26 which outputs an audible frequency signal from the frequency dividing circuit 16 in response to this coincidence output, and a notification circuit 28 which generates a notification sound based on the output from the AND gate 26.

The count outputs of the current time counter 18 and the alarm counter 22 are supplied to a display switching circuit 30, where either one is selected and input to the display section 34 via the decoder/driver 32.

On the other hand, the correction circuit 36 includes a conduction time counter 38,
Continuity number counter 40, occurrence time detection circuit 42,
It consists of a modification completion signal generation circuit 44 and a switching gate circuit 46.

Of these, counter 4 in the conduction time counter 38
The output signal of 8 is inverted and input to an AND gate 50 connected to the clock input φ of the counter 48. Therefore, when the count value of the counter 48 is an intermediate value, an H level signal is input to the AND gate 50, and the constant period signal φ ₁ from the frequency dividing circuit 16 is passed through the AND gate 50 to the counter 4.
8 and counting is performed, and when the final output signal becomes H level, AND gate 50 closes and stops counting.

When the switch 2 is touched here, an H level signal is generated on the signal line B regardless of the direction of the touch, and is inputted to the reset input R of the counter 48 via the AND gate 52. As a result, the count value of the counter 48 is cleared, and its final output signal becomes L level. This causes counter 4
8 starts counting again, and after a certain period of time, the final output signal rises to H level. Catching this rising edge, the Q output signal of the FF 54 becomes H level.

Further, the signal line B of the switch 2 is input to the AND gate 56 in the conduction number counter 40. This AND gate 56 has a counter 48 and a counter 5.
When the final output signal of switch 8 is inverted and input, and both counters 48 and 58 do not have the final count value, the counter 58 counts the number of times switch 2 is turned on and off. When the number of times reaches the set value, the final output signal of the counter 58 becomes H level and counting is stopped. Further, when a certain period of time has elapsed since the switch 2 was touched, the final output signal of the counter 48 becomes H level, so that counting is similarly stopped.

The final output signals of the counters 48 and 58 are the clock input φ of the FF 60 in the generation timing detection circuit 42,
Input each to the D input. Therefore, for example, if only the final output signal of the counter 48 rises, which occurs when the pattern shown in FIG.
The Q output of 60 remains at L level. Conversely, the final output signal of the counter 58 first rises to the H level, and then the final output signal of the counter 48 rises to the H level.
If it rises to the level, this changes the pattern to c-
This corresponds to the case of touching in the d direction, but in this case
The Q output of FF60 becomes H level.

The Q output of this FF60 is the signal of switch 2 and the FF
It is input to the switching gate circuit 46 along with the Q output of 54. Of these, the signals from switch 2 and FF 54 are directly connected to the AND gate 6 in the switching gate circuit 46.
However, the Q output of the FF 60 is input to the AND gate 62 as is, and is inverted and input to the AND gate 64. The output signal of the AND gate 64 is input to the time counter 18 via the OR gate 66, and the output signal of the AND gate 64 is input to the alarm counter 22.

Therefore, when the switch 2 is touched in the a-b direction, the Q output of the FF 60 becomes L level, and the subsequent correction pulse signal from the switch 2 is supplied to the time counter 18. Conversely, switch 2 to c-
When the change occurs in the d direction, the Q output of the FF 60 becomes H level, and the correction pulse signal from the switch 2 is supplied to the alarm counter 22. Also, FF
The Q output signal of 60 is also input to the display switching circuit 30, and when the Q output is at H level, the output of the alarm counter 22 is output, and when the Q output is at L level, the output of the current time counter 18 is output to the display section 34. It is configured to supply

Furthermore, the modification completion signal generation circuit 44
When the Q output of becomes H level, the AND gate 68
is opened to supply the constant periodic signal φ ₂ from the frequency divider circuit 16 to the clock input φ of the counter 70 . Counter 70 counts this. Thereafter, when the final output signal of the counter 48 becomes H level and the switch 2 is turned on, the output signal of the AND gate 72 becomes H level, whereby the counter 70 is reset and starts counting again from the beginning. If this condition does not occur for a certain period of time or more, that is, when the correction is completed, the counter 70
The final output signal becomes H level, thereby resetting the counter 58 and FFs 54 and 60 to return them to their initial states.

In this way, if the switch 2 is touched in the a-b direction, the correction pulse generated by the subsequent touch of the switch 2 will be used to adjust the current time, and if the switch 2 is touched in the c-d direction, the display will become the alarm time. Alarm time can be adjusted. After the modification is complete, if nothing is done for a certain period of time, it will return to the initial state.

(Effect of the invention) As described above, according to the invention, the mode to be corrected can be switched between the current time and the additional function depending on the direction in which the switch is first touched.
Other than the one correction switch, there is no need for any switches for switching modes. Furthermore, this switching operation is very simple, just changing the direction in which you touch the switch, and there is no chance of erroneous or forgotten operations, making it very easy to use.
