Description

[Detailed description of the invention] [Industrial application field] The invention is an alarm clock that can be hung from the ceiling or pillar, and when the alarm sound is emitted, it descends and comes down to the user's ear. It is a clock with an alarm.

[Prior Art] Today, various improvements have been made to alarm clocks to ensure that they wake up. For example, the clock body is hung from the ceiling or a pillar, and when the alarm of the alarm clock starts sounding, the clock is activated. In some cases, the body winds up a hanging string and moves upwards away from the user (for example, Utility Model Application No. 61-1191, Utility Model Application No. 61-96390).

In a clock with an alarm that rises by winding up a hanging string like this, when the alarm starts sounding, the clock body moves away, so the user has to get up to stop the alarm sound, making sure to wake up. It is something.

However, with hanging alarm clocks that rise when the alarm sound is emitted, the clock body gradually moves away from the user when the alarm starts sounding, so the alarm sound gradually becomes quieter for the user. There are cases where the user may fall asleep due to the audible changes, and there is also the disadvantage that it becomes a nuisance if the watch body is hung close to the ear until the alarm notification sound begins to sound.

For this reason, as a hanging alarm clock,
Alarm watches have been devised that are usually hung at a high position, but when the alarm sound starts to sound, the watch body is lowered and the sound is emitted close to the user's ear.

[Problems to be solved by the invention] The watch body that descends when the alarm sound starts to sound is capable of making the user hear the alarm sound gradually louder and ensuring a wake-up effect. When a user hangs a watch body from a ceiling or a pillar, the hanging height varies, and there are cases where the watch body does not descend properly to near the user's ear, or when the watch body hangs from the floor or the user's body. There are drawbacks such as the possibility of falling too far down.

[Means for Solving the Problems] The present invention provides a timepiece body that is suspended by a motor so that it can be raised and lowered, and includes a first motor drive circuit that lowers the timepiece body and a second motor drive circuit that raises the timepiece body. and detecting a coincidence signal that is a control signal for operating a sound generation circuit that emits an alarm notification sound, and when the coincidence signal is output, a lowering operation that operates the first motor drive circuit. A signal generating circuit is provided, and a rising operation signal generating circuit is provided to operate the second motor drive circuit when the output of the coincidence signal stops, and the distance between the bottom surface of the watch body and the floor surface is detected and the movement is lowered. A descent distance detection circuit that stops the generation of the descent signal from the operation signal generation circuit, and a descent distance detection circuit that stores the descent time of the watch body and, when the output time of the rise signal matches the descent time, outputs the rise signal from the rise operation signal generation circuit. A rising position detection circuit is provided to stop the occurrence of this phenomenon.

[Function] The present invention has a first drive circuit and a second drive circuit that drive the motor, and the first drive circuit drives the motor to lower the suspended watch body. In addition, the second driving circuit can drive the motor to raise the watch body.

The detection body detects the distance between the watch body and the floor surface, etc., and the descent distance detection circuit can always stop the descent of the watch body at a fixed position from the floor surface. However, the raised position detection circuit always allows the watch body to be raised by a distance equal to the lowered distance, thereby returning the watch body to its original height position.

[Example] As shown in FIG. 3, the elevating alarm clock according to the present invention has a hanging device 11 such as a hook or a hanging ring at the tip.
The watch body 112 can be suspended by a hanging cord 108 having a diameter of 0.0, and a drive motor 94 is installed inside the watch body 112, as shown in FIG.
Worm gear 102 attached to the motor shaft of
A reduction gear train mechanism 104 in which gears are appropriately combined to sequentially lower the rotation speed from the gears, and a pulley 106 that is rotated at a low speed via the reduction gear train mechanism 104. By wrapping the suspension string 108 around the pulley 106, it can be moved up and down.

The electric circuit in the watch body 112 is
As shown in FIG. 1, a reference signal from a reference signal generating circuit 12 such as a crystal oscillator is frequency-divided by a frequency dividing circuit 14, and then sent to a time display mechanism 16 as a reference frequency signal of an appropriate period. This is similar to a conventional electronic watch.

This time display mechanism 16 includes a time counter 18,
It is composed of a decoder driver 20 and a time display section 22, and the clock signal from the time counter 18 is sent to the decoder driver 20.
It is also sent to the match detection circuit 24 in .

This alarm circuit 32 is composed of an alarm memory, a coincidence detection circuit, a pulse generator, a flip-flop, and a timer, and sends a coincidence signal to an AND circuit 34 (described later) for a certain period of time after the displayed time coincides with the alarm set time. .

That is, the coincidence detection circuit 24 in the alarm circuit 32 is not only sent the clock signal which is the count value of the time counter 18 as described above, but also is sent the set value from the alarm memory 26, and when the coincidence detection circuit 24 is sent, the set value from the alarm memory 26 is also sent. The circuit 24 outputs a match signal when the count value and set value match. Since this coincidence signal is input to the set input of the flip-flop 28 via the pulse generator 27, when the coincidence signal is output from the coincidence detection circuit 24, the flip-flop 28 is set to the set state, and the Q output signal and the output signal are inverted. become. Since the Q output signal of the flip-flop 28 is used as the reset input signal of the timer 30, a coincidence signal is output from the coincidence detection circuit 24, and when the output signal of the flip-flop 28 is inverted from the H level to the L level, the timer 30 is reset.
The reset state of is released, the timer 30 counts the _φ1 signal from the frequency dividing circuit 14, and outputs a carry signal after the required time. Since this carry signal is used as a reset signal for the flip-flop 28, the coincidence signal is output from the coincidence detection circuit 24, and after the Q output signal and the output signal of the flip-flop 28 are inverted, the carry signal is reset. This causes flip-flop 28 to return the Q output and output to their initial states. Therefore, if the Q output signal of flip-flop 28 is used as a coincidence signal from alarm circuit 32, alarm circuit 32 can output a coincidence signal having a fixed time length.

The Q output terminal of the flip-flop 28 in this alarm circuit 32 is connected to the input terminal of an AND circuit 34, and the other input terminal of the AND circuit 34 is connected to the H level side of the power supply via an alarm set/non-set switch 36. By connecting the output terminal of the AND circuit 34 to the sound generation circuit 38, the AND circuit 34 allows the match signal from the alarm circuit 32 to pass when the set/non-set switch 36 is in the on state, thereby causing the sound generation circuit 38 to generate an alarm notification sound. to pronounce. Then, when the coincidence signal from the alarm circuit 32 is interrupted or when the set/unset switch 36 is turned off, the AND circuit 34 is closed and the alarm notification sound is stopped.

As described above, in the present invention, the clock circuit 40 includes a descending operation signal generating circuit 42, a descending distance detecting circuit 56, an ascending operation signal generating circuit 48, an ascending position detecting circuit 70, a first driving circuit 84, and a second driving circuit. 92, when the AND circuit 34 in the clock circuit 40 outputs a coincidence signal to the sound generation circuit 38, the first pulse generator 44 in the falling operation signal generation circuit 42 outputs a coincidence signal to the sound generation circuit 38.
generates a single H pulse when the coincidence signal is generated, and sets the first flip-flop 46 to the set state.

Therefore, the first flip-flop 46 outputs an L-level drop signal at its output, and the drop signal is sent to the first drive circuit 84, making each transistor of the first drive circuit 84 conductive and driving the motor. The watch body 112 can be lowered by driving. At this time, the Q output of the first flip-flop 46 becomes H level, and the start signal, which is the H level signal, is sent to the descending distance detection circuit 56 and the ascending position detection circuit 70.

In the descent distance detection circuit 56, when the start signal is sent from the descent operation signal generation circuit 42, the switch 58 is turned on, the light emitting diode 60 starts emitting infrared rays, and the phototransistor 64 detects the reflection of this infrared ray from the floor. Light is received and the watch body
As the voltage decreases by 12, the resistance value of the phototransistor 64 decreases, and the voltage drop across the phototransistor 64 also gradually decreases. The voltage drop across the phototransistor 64 is compared with the reference voltage in the comparator 66, so when the watch body 112 falls to a certain distance from the floor and the voltage drop across the phototransistor 64 drops to a certain value, the comparator 66 outputs an output. becomes H level, and the third pulse generator 68 outputs an H pulse stop signal. This stop signal is sent to the lowering operation signal generating circuit 42 to return the first flip-flop 46 to the reset state, stopping the output of the start signal and lowering signal from the lowering operation signal generating circuit 42, and thereby lowering the watch body 112. to stop.

The start signal, which is the Q output of the first flip-flop 46, is sent to the ascending position detecting circuit 70 as well as the descending distance detecting circuit 56, and while the start signal is being output, the first The AND circuit 72 is opened to allow the φ ₁ signal to pass, and the φ ₁ signal that has passed through the first AND circuit 72 is sent to the up-down counter 78 through the OR circuit 76.

And alarm set/unset switch 36
When the sound generation of the alarm notification sound is stopped, such as when the alarm notification sound is opened, the coincidence signal from the AND circuit 34 to the sound generation circuit 38 disappears, and the rising operation signal generation circuit 48 to which the coincidence signal is sent is connected to the inverter 50. Since the second pulse generator 52 is provided through the
2 outputs an H pulse. Since this H pulse signal is used as the set input signal of the second flip-flop 54, when the coincidence signal disappears, the second flip-flop 54 is placed in the set state, and the H pulse signal is output from the Q output terminal.
A level restart signal is sent to the raised position detection circuit 70, and an L level raised signal is output from the output terminal, and the raised signal is sent to the raised position detection circuit 70 and the second drive circuit 92.

This rising signal makes each transistor in the second drive circuit 92 conductive, allowing the motor 94 to reverse and raise the watch body 112. At this time, the rise signal is also sent to the rise position detection circuit 70, causing the up-down counter 78 in the rise position detection circuit 70 to be in a down count state, and is also sent to the Q output of the second flip-flop 54 in the rise operation signal generation circuit 48. The restart signal is also sent to the up position detection circuit 70, which opens the second AND circuit 74 in the up position detection circuit 70, and inputs the φ ₁ signal from the frequency divider circuit 14 to the up/down counter 78 via the OR circuit 76. do. Therefore, the up-down counter 78 is similar to the clock body 112.
While the clock body 112 is rising sequentially, subtraction is performed based on the _φ1 signal from the number of pulses of the signal counted when the clock body 112 is falling, and when the count value reaches zero, the entire output is set to H level, The output of the third AND circuit 80 to which this signal is input is set to H level. Therefore, the fourth pulse generator 82 outputs an H-pulse stop signal, which is applied to the second flip-flop 54 in the rising operation signal generating circuit 48.
is reset, and the output of the restart signal and the rise signal from the rise operation signal generation circuit 48 is stopped.

In this way, the raised position detection circuit 70 raises the watch body 112 for the same time as the time the watch body 112 is lowered by the up-down counter 78, thereby returning the watch body 112 to its original height. It is also possible to use two up-down counters instead of one up-down counter.

As _an embodiment of the up position detection circuit 70 using two up counters, as shown in FIG.
The output terminal of the second AND circuit 74, which receives the _{φ1 signal} and the restart signal, is connected to the _φ1 input terminal of the second up counter 98, and the first up counter 96 and the second up counter 98 are connected to each other. Each output of the counter 98 is led to a coincidence detection circuit 100, and the output of the coincidence detection circuit 100 is used as a stop signal via the fourth pulse generator 82, so that the stop signal is taken out from the ascending position detection circuit 70. It is. In this case, in the up position detection circuit 70, the output terminal of the pulse generator 82 is connected to the reset input terminals of the first up counter 96 and the second up counter 98 to provide a reset signal.

[Effect of the invention] The elevating alarm clock according to the invention outputs a descending signal based on the generation of an alarm sound by the descending operation signal generating circuit, and then causes the first drive circuit to rotate the motor in the forward direction, thereby starting the clock. When the body is lowered, the rising operation signal generation circuit outputs a rising signal based on the stop of the alarm notification sound, and the second drive circuit reverses the motor and raises the watch body. Therefore, the alarm setting is possible. When the time comes and the alarm notification sound is emitted, the watch body is lowered so that the user can hear the alarm notification sound gradually louder, thereby ensuring a wake-up effect. When the alarm sound is stopped, the clock body automatically rises, so there is no need to wind up the hanging cord after using the alarm. And when the clock body descends,
The descending distance detection circuit lowers the watch body to a certain height from the floor, etc., and when the watch body rises, the rising position detecting circuit causes the watch body to rise for the same amount of time as the descent time, returning the watch body to its original position. It can be returned to the height position.

Therefore, since the watch body according to the present invention is normally suspended at a high position when the alarm notification sound is not emitted, it does not disturb the user, and only when the alarm notification sound is emitted, the watch body is suspended at a high position. It lowers to an appropriate height, near the patient's ears, and makes a loud sound that ensures that the patient wakes up.
