Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a timer-equipped timepiece device that combines a reference-equipped clock structure and a timer structure to provide a new timer function in addition to the normal reference function and timer function.

BACKGROUND ART Conventionally, a timer-equipped timepiece device that combines a clock structure and a timer structure has been devised, which has the advantage of being able to utilize two functions with one timepiece device.

In other words, a conventional timer clock device has a clock configuration that appropriately decelerates the rotation of a motor serving as a reference rotation source, displays the time, generates a reference output from a reference contact at a set time, and performs a reference operation, and a timer set. By rotating the display board in the set direction, the motor as the reference rotation source starts operating.
The rotation of the motor is appropriately decelerated to rotate the timer set display plate in the non-set direction, and after the set time has elapsed, a timer component is coupled to generate a timer output from a timer contact to perform a timer operation. . In this timer-equipped clock device, the clock component can be used as an alarm clock.
On the other hand, the timer component can be used for notifications of bath boiling time, cooking time, etc.

The present invention utilizes a new timer function by controlling the state in which the timer function in the conventional timer-equipped clock device is controlled by the clock component operation and the state in which it can operate independently by combining and separating both components. This made it possible.

A characteristic configuration of the present invention is that in a timer-equipped timepiece device having a clock component and a timer component, the clock component and the timer component can be separated and combined;
When the two components are connected, a joining contact is provided that provides electrical continuity between the two components, and when the two components are connected and the joining contact is in a conductive state, rotation of the motor of the timer component is prohibited by operating a noise stop switch in the operable state, and the switch is activated. The present invention consists of a timer function switching circuit that allows the motor rotation to operate independently when the junction contact is non-conducting, separate from the state in which the prohibition is canceled by operation in the disabled state.

In addition, the above-mentioned timer function switching circuit in the characteristic configuration of the present invention prohibits the rotation of the motor in the timer component before the target output is generated by operating the stop switch in the operable state, and prohibits the rotation after the target output occurs. It is also effective to be able to switch between a state where the state is canceled and a state where independent operation is possible.

Hereinafter, the present invention will be explained in detail based on Examples.

FIG. 1 shows an external view of a timer-equipped clock device as an embodiment of the present invention in a connected state;
The figure shows an external view of the separated state. First, the operation will be explained with reference to the circuit diagram of the first embodiment shown in FIG.

The timer-equipped clock device 2 consists of a clock component 4 and a timer component 6. Waveform shaping 14
Pulses capable of driving the timepiece step motor 20 are alternately applied to the coil 18 by the drive inverters 16a and 16b. The rotation of the motor 20 is suitably slowed down by a clock train 22 to enable a time display 24 with hour, minute and second display blades.
The reference contact 26 is used to generate a reference output 26a at the reference time set by the user. For example, the reference contact 26 is used to generate a reference output 26a at a reference time set by the user. Turn on the board
This is to generate an H output at a standard set time by moving the controller. This reference output 26a is supplied to an AND gate 34. The other input terminal of the AND gate 34 is connected to the reference signal φa (for example, 2048 Hz) for generating an alarm sound from the frequency dividing circuit 12 and the output of the stop switch 30 to the chattering prevention circuit 32.
Supplied via. The output of the AND gate 34 is supplied to the time signal circuit 36, and when the reference output 26a is generated from the reference contact 26 with the ring stop switch 30 in the closed state, a reference signal φa for generating an alarm sound is sent to the time signal circuit 36. It is understood that the alarm sound is generated by the speaker 38.

On the other hand, the timer component 6 includes an oscillation circuit 80, a frequency dividing circuit 82, and a waveform shaping circuit 84 independently of the clock component 4.
The drive inverters 86a and 86b alternately apply pulses to the coil 88 to drive the timer step motor 90. The motor 9
The rotation at zero is appropriately decelerated by the timer train 92, causing the timer display plate 94 to rotate (one rotation every approximately 60 minutes in this embodiment). The rotational operation of the timer step motor 90 is controlled by the timer contact 96, that is, when the user rotates the timer display plate 94 to set the timer, the timer operation output 96a becomes H and is activated. That is, the H output of the timer operation output 96a is connected via a multiplexer 114 to the gate inputs of N-MOS transistors 116 and 118 that control the power supply to the drive inverters 86a and 86b, and the rotation of the timer step motor 90. Drive can be controlled.

Timer sound generation output 96b from timer contact 96
is supplied to the AND gate 98, and the other input terminal of the AND gate 98 receives a reference signal φb (for example, 1024
Hz) is supplied, so the timer sound generation output 9
6b becomes H, the reference signal φ is sent to the time signal circuit 100.
It is understood that the timer sound is generated by the speaker 102 when the signal b is supplied.

The above-mentioned timer contact 96 is not shown in detail, but is obtained by a well-known timer contact configuration consisting of a movable contact placed on the back of the timer display plate 94 and a fixed contact that slides thereon. When rotated, the timer operation output 96a becomes H, and after a set time elapses, the timer sound generation output 96b becomes H for a certain period of time.

On the other hand, in the clock component 4 and the timer component 6,
Timer function switching circuits 200 and 300 are configured, respectively. The timer function switching circuit 200 outputs the output of the ring stop switch 30 to the timer component 6 via an inverter 56 and an OR gate 54.
It is output as a. Further, the circuit 200 is
A level signal is output to the timer configuration section 6.
The output states of these two outputs can be switched by junction contacts 60 and 70. Timer function switching circuit 300 of timer component 6
is composed of an AND gate 110, an OR gate 112, and a multiplexer 114, and one input terminal of the AND gate 110 has the above-mentioned output 54.
a is supplied through the junction contact 60, and an H level signal is supplied to the OR gate 112 through the junction contact 70. The output of AND gate 110 is supplied to input terminal X1 of multiplexer 114. On the other hand, the timer operation output 96a from the timer contact 96 is supplied to the other input terminal of the AND gate 110 and the input terminal X2 of the multiplexer 114. The output of OR gate 112 is supplied to output switching control terminal A of multiplexer 114. The selected output from output terminal X of multiplexer 114 is supplied to AND gate 98 and N-MOS transistors 116 and 118. In the multiplexer 114 here, when the input to the output switching control terminal A is at H level, the input signal of input terminal X1 is selected and output from the output terminal X, and when it is at L level, the input signal of input terminal X2 is output. It is set to be output from terminal X.

Therefore, when the junction contacts 60 and 70 are in a conductive state (the state shown in FIG. 1) and the anti-squeal switch 30 is open, the timer operation is controlled only by the timer operation output 96a of the timer contact 96; 30 is closed, the N-MOS transistors 116 and 118 are always turned off, so the timer operation is forcibly prohibited regardless of the output of the timer operation output 96a. On the other hand, it will be understood that when the junction contacts 60 and 70 are brought into a non-conductive state (the state shown in FIG. 2), the timer operation is controlled only by the timer operation output 96a, regardless of the operation of the anti-squeal switch 30.

The conduction and non-conduction of the joining contacts 60 and 70 can be controlled by whether the timepiece component 4 and the timer component 6 are coupled or separated. As shown in FIG. 1, when the coupling grooves and protrusions formed in both structures are coupled and inserted, the contact structures forming the bonding contacts 60 and 70 contact each other and conduct. When separated as shown in the figure, there is no contact and therefore no conduction.

On the other hand, the timer function changeover switch 50 is a control switch for when it is desired to perform the timer operation regardless of the operation of the ring stop switch 30 even when the clock component 4 and the timer component 6 are combined. If the switch 50 is closed, the timer will operate even when both configurations are connected to the timer operation output 96a.
controllable only by

On the other hand, the output X of the multiplexer 114 is also supplied to an AND gate 120, and this AND gate 1
A reference signal φc (for example, 1 Hz) for blinking display is supplied from the frequency dividing circuit 82 to the other input terminal of 20, and when the output X of the multiplexer 114 is H, the reference signal φc is simultaneously supplied from the AND gate 120.
c is outputted to the LED drive circuit 122, and the LED display unit 124 performs an LED blinking display. That is, the blinking display of this LED indicates when the timer step motor 90 is in a rotating state, that is, when the timer function is in an operating state.

The first embodiment has the above-mentioned configuration, and its operation will now be explained using the time charts shown in FIGS. 4 and 5.

First, the operating state when the clock component 4 and the timer component 6 are separated and their timer functions are operated independently will be described.

The state shown in FIG. 4A shows the state before the timer function is set; the timer operation output 96a from the timer contact 96 is L, and the timer step motor 90 is in a stopped state. In the state shown in Fig. 4B, the timer display board 94 is turned 10 to operate the timer function.
The timer operation output 96a of the timer contact 96 becomes H. Since the junction contacts 60 and 70 are non-conductive, the output of the OR gate 112 becomes L, so the input signal of the input terminal
16 and 118 are turned on to put the timer step motor 90 into a rotating state. In the state shown in Fig. 4 (c), the timer set time of 10 minutes has elapsed and the timer contact 9
The timer sound generation output 96b from 6 becomes H, indicating that a timer sound is generated. This output 96
The output width of b is obtained by the corresponding contact width of the timer contact 96, and the timer is automatically stopped without any special stopping operation.

The rotation of the timer step motor 90 continues even after the timer sound generation output 96b outputs H, and when the timer display plate 94 is rotated to the state shown in FIG. 4D, the timer operation output 96a becomes L and the motor 90
stops.

Note that the timer sound generation due to H of the timer sound generation output 96b automatically stops as the timer step motor 90 continues to rotate, but the timer display board 94 is forced to change from the state of C to the state of You can also instantly stop the timer sound by rotating it.

Next, a description will be given of how to combine the clock component 4 and the timer component 6 and control the timer function by the reference mechanism of the clock component 4. This is the fifth
As shown in the time chart in the figure, the timer function changeover switch 50 in this case is opened. In the state shown in FIG. 5A, the noise stop switch 30 is closed and the timer display plate 94 is set to 10 minutes. The timer operation output 96a becomes H due to the set rotation of the timer display board 94, but since the noise stop switch 30 is in the closed operation state, the output that passes through the inverter 56 is L, and therefore the output of the AND gate 110 becomes L. . In this case, the junction contacts 60 and 70 are in a conductive state, so the OR gate 1
The output of the timer 12 is H, and the input of the input terminal X1 is outputted to the multiplexer 114, so the timer step motor 90 is in a stopped state. In the state shown in FIG. 5B, when the reference setting time of the clock component 4 is reached, the reference output 26a of the reference contact 26 becomes H, the reference signal φa for generating an alarm sound is output from the AND gate 34, and an alarm sound is generated. , when the noise stop switch 30 is opened to set the output to L in order to stop the noise. This noise stop switch 3
Since the output of 0 becomes L, the output of the AND gate 110 becomes H, and the timer step motor 90 starts rotating.

The state shown in Fig. 5C is the timer step motor 90.
The timer display plate 94 rotates in the non-setting direction due to the rotation of , and when the timer set time has elapsed, the timer sound generation output 96b of the timer contact 96 becomes H, indicating that a timer sound has been generated. The output width of the timer sound generation output 96b is obtained by the corresponding contact width of the timer contacts 96, and is automatically stopped without any particular stopping operation.

The rotation of the timer step motor 90 continues even after the timer sound generation output 96b outputs H, and when the timer display plate 94 is rotated to the state shown in FIG. 5D, the timer operation output 96a becomes L and the motor 90
stops.

What is distinctive about the operation of the timer chart in Figure 5 mentioned above is that the timer sound can be used as the second alarm sound, making it possible to obtain the reference function of two clocks with one clock. It's all about what you can do. To actually use it, first set the approximate time on the clock component 4 to the time you want the alarm to sound,
After that, at the time when you want to sound the second alarm sound (timer sound), the timer display board 94 in the timer configuration section 6 displays the difference between the first alarm time and the second alarm time.
You can set it by rotating it. Specifically, if the first alarm is set at 7:00 a.m. in the clock component 4, and you want the second alarm to sound at 7:10 a.m., set the timer display board 94 of the timer component 6 to 10. Rotate it to the minute position. By doing so, 10 minutes after the alarm sound is generated at 7:00 a.m. and the sound stop switch 30 is opened,
That is, the second alarm sound (timer sound) is generated at 7:10 am.

These functions are extremely useful as they allow one watch to be used to wake up two users at different morning wake-up times, or to manage the time from when they wake up in the morning until they go to work. It is valid.

A characteristic feature of this embodiment is that the timer function can be used independently or restricted by the operation state of the ring stop switch 30 of the watch component, which can be controlled by the timer component 4 and the timer component 6. It is possible to control the timer sound by combining or separating them, and it is possible to use the timer sound as a timer operation not only as a simple timer notification but also as a second alarm sound.

Note that when the timer function changeover switch 50 is closed, the timer function stops ringing even if the clock component 4 and timer component 6 are connected, as in the time chart shown in FIG. This means that the operation can be performed regardless of the operation of the switch 30.

Next, a second embodiment of the present invention will be described.

The second embodiment is shown in the circuit configuration diagram of FIG. 6, and since the basic configuration is the same as that of the first embodiment, the same configurations will be designated by the same reference numerals and a description thereof will be omitted.

The difference from the first embodiment is that the input signal at one end to the OR gate 54 in the timer function switching circuit 200 of the clock component 4 is different. Specifically, the output of the AND gate 34 is
0. That is, the first
In the embodiment, the timer function was controlled only by the operation state of the noise stop switch 30, but in the second embodiment, the timer function was controlled only by the operation state of the noise stop switch 30 and the reference contact 26.
The feature is that the timer function is controlled by the reference output 26a from the .

The AND gate 34 includes the standard output 26a of the standard contact 26 of the clock component 4 and the ring stop switch 30.
output is supplied, and the noise stop switch 30
is in the closed operation state and when the reference output 26a is generated, that is, when the reference set time is reached, an H output is generated. This H output is supplied to a melody sound generation circuit 40, which generates a melody sound as an alarm sound. It is assumed that the frequency signal φa necessary for forming the melody sound is directly supplied to the melody sound generation circuit 40. On the other hand, the output of the AND gate 34 is also supplied to the set input S of the flip-flop 130, and when the H signal of the AND gate 34 rises at the reference setting time, the output Q is set to H, and the H signal is passed through the OR gate 54. The signal is supplied to the AND gate 110 of the timer configuration section 6.

That is, in this second embodiment, when the clock component 4 and the timer component 6 are combined, the operation of the timer function is forcibly prohibited until the output timing of the reference output 26a when the ring stop switch 30 is closed. It is something. The flip-flop 130 is reset by supplying the output of the quench switch 30 to the reset input R via the one-shot circuit 132.

Next, the operation of the second embodiment will be explained.

The operation when the clock component 4 and the timer component 6 are combined will be explained using the time chart shown in FIG. 7. The state in FIG. 7A shows the state before the timer function is set; the timer operation output 96a from the timer contact 96 is L, and the timer step motor 90 is in a stopped state. In the state shown in FIG. 7B, the noise stop switch 30 is closed and the timer display plate 94 is set to 10 minutes. The timer operation output 96a becomes H due to the set rotation of the timer display board 94, but the AND gate 34
Since the output of the flip-flop 130 is L, the AND gate 110 remains at L since the Q output of flip-flop 130 is L. Multiplexer 114 connects junction contact 6
0 and 70 are in a conductive state, the output of the OR gate 112 is H, and the multiplexer 114 outputs the input of the input terminal X1 to which the output of the AND gate 110 is supplied, and in this state, the timer step motor 90 is It is a stop. In the state shown in FIG. 7C, when the reference setting time of the clock component 4 is reached, the reference output 26a of the reference contact 26 becomes H, and the melody sound generation circuit 40 starts notifying the melody as an alarm sound from the speaker 38. It shows the condition. Furthermore, the H output of the reference output 26a is determined by setting the output of the AND gate 34 to H and flip-flop 1.
30 becomes H, and when the output of AND gate 110 becomes H, the timer step motor 90 starts rotating. Thereafter, the melody notification is stopped by opening the ring stop switch 30. However, even if the above-mentioned melody notification is stopped, the Q output of the flip-flop 130 is maintained at H, and the rotational operation of the timer step motor 90 continues. In the state shown in FIG. 7D, 10 minutes of the timer set time have elapsed since the timer step motor 90 started rotating, and the timer sound generation output 96b becomes H and a timer sound (used as a second alarm sound) is generated. The state shown in FIG. 7E shows a state in which the timer operation output 96a from the timer contact 96 becomes L due to the rotation of the timer display plate 94, and the timer step motor 90 is stopped.
Although this time chart shows a state in which the melody notification is stopped for a short period of time, it is also possible to stop the melody notification immediately after the state shown in FIG. Even if it continues to sound, a timer sound is generated in the state shown in FIG. 7D, and the melody notification can be stopped after that.

The second embodiment enables similar operations to the first embodiment described above, but the timing of the rotational operation of the timer step motor 90 is different. That is, in the first embodiment, the motor 90 starts rotating when the noise stop switch 30 is opened from closed, but in the second embodiment, the motor 90 starts rotating when the standard output 26a switches from L to H. is configured to start rotating.

Note that in the second embodiment, as in the first embodiment, when the clock component 4 and the timer component 6 are separated and the junction contacts 60 and 70 are brought into a non-conducting state, the timer function is controlled by the clock component. It can operate independently regardless of the operation of section 4. Further, even when the clock component 4 and the timer component 6 are combined, the timer function can be operated independently by closing the timer function changeover switch 50.

Next, a third embodiment of the present invention will be described.

The third embodiment is the timepiece component 4 in the second embodiment described above.
This circuit is simply a modification of the timer function switching circuit 200, and the output of the AND gate 34 is directly supplied to the OR gate 54 without going through a flip-flop. The operation of the third embodiment is characterized in that when the clock component 4 and the timer component 6 are combined, the timer function can only operate while the melody sound is being generated as an alarm sound.

In the above embodiment, the timer component is of the type that generates a timer sound after the set time has elapsed. A similar effect can be obtained with a timer mechanism that controls ON and OFF.

As explained above, the present invention is configured such that the reference clock component and the timer component can be separated and combined,
When the two components are separated, the timer function of the timer component can be operated independently, while when combined, the timer function is prohibited when the ring stop switch of the clock component is operated in the operable state. Therefore, the timer component can be used in two ways: as a normal timer function and as a second alarm operation. That is, if it is desired to use the timer component as a normal timer function, the timer function can be operated independently by separating the timer component from the clock component. On the other hand, if it is desired to use the timer component for the above-mentioned second alarm operation, the timer component is coupled to the clock component and the junction contacts are brought into conduction. Then, rotate the timer display board by the amount of time you want the second alarm to operate, that is, the difference between the estimated set time and the scheduled time for the second alarm, and then operate the sound stop switch to enable the alarm. . By doing so, the timer operation is forcibly prohibited until the reference set time, and the timer notification is made with a delay of the timer set time after the alarm operation, and the timer notification can be used as the second alarm notification. The operation of this second alarm notification is 1
The clock device can be used as an alarm function to wake up two people, and a clock device with a new function can be provided. Furthermore, the above-mentioned timer function of the timer component in the present invention can be switched by a simple operation of separating or combining the timer component with the clock component, which is of great practical value. It is something.
