Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a timepiece with a movable decorative body.

Conventionally, devices equipped with movable decorations, such as cuckoo clocks and alarm clocks whose bells are struck by a doll, have many disadvantages in terms of structure and cost because they generate sound mechanically. Cuckoo clocks require bellows, which makes them more complex and has problems in terms of durability. In addition, in the case of a bell tolled by a doll, the bell and the hammer used to strike the bell had to be made of metal, and the supporting structure of the bell was complicated, resulting in a disadvantage in terms of cost.

Therefore, the present invention aims to eliminate the above-mentioned drawbacks of the conventional art by generating electronic sound in synchronization with the movement of the movable decoration.

An embodiment of the present invention will be described below based on the drawings. In Figure 1, Q is an oscillator, D is a frequency divider,
DR is a drive circuit for the motor M , and ST is a setting circuit that presets the number of alarm sounds. _TM1 ,
TM ₂ is a timer circuit, F ₁ to _{F 3} are flip-flop circuits, W ₁ and W ₂ are one-shot pulse generators,
G ₁ and G ₂ are gate circuits, and V is an inverter.
AL is an alarm control circuit, and SP is a sounding device.
ML is a motor, and the movable decorative body A is driven by the rotation of this motor. In this example, movable decorative body A
This uses a doll with a hammer, which swings and strikes (but does not actually strike) the bell as the motor ML rotates.

S is a switch opened by a cam or the like (not shown) as the motor M rotates. SA is an alarm switch, and SS is a silence switch.

Next, the operation will be explained. When the alarm time arrives, switch SA closes and one pulse is generated from the one-shot pulse generator _W1 , and the down counter DC
The contents of the setting circuit ST are preset, and the flip-flop circuit _F1 is also set. By setting the flip-flop circuit _F1 , the motor ML
rotates, and the movable decorative body A is driven. This movement of the movable decorative body A closes the switch S, and one pulse is generated from the one shot pulse generator _W2 . This pulse causes the contents of the down counter DC to be counted by one, and the timer circuit
TM ₂ works. The timer circuit _TM2 generates an output after a certain period of time, that is, in synchronization with the action of the doll, which is a movable ornament, striking a bell, and the flip-flop circuit _F3 is set. As a result, an output is generated from the alarm control circuit AL, and an electronic bell sound is sounded from the sound generating device SP . It looks as if the doll is actually ringing the bell.

The above operation is repeatedly performed by rotating the motor ML. When the stop switch SS is closed, the first pulse from the one-shot pulse generator _W2 causes the output of the flip-flop circuit _F2 to become "1", and the timer circuit
TM ₁ works. The output from this timer circuit _TM1 after a certain period of time causes the flip-flop circuit to
_F1 is reset, motor ML is stopped, and the sound is stopped. The setting time of timer circuit TM ₁ is
The time is set for the doll to return to its original position after it makes the action of hitting the bell. Therefore, no matter what timing the ring stop operation is performed, the doll will surely return to its original position.

If the ringing stop operation is not carried out, when the content of the downtown controller DC becomes D, the same operation as if the switch SS is closed is performed by the output thereof, and the ringing is stopped.

FIG. 2 shows an example of use in a time signal clock, in which CT ₁ is a 60-minute counter, CT ₂ is an hour counter, and other configurations are the same as in FIG. 1.

In the above configuration, when the hour comes, the counter
One-shot pulse generator with output generated from CT ₁
One pulse is generated from W ₁ . This pulse causes the contents of the counter _CT2 to be preset to the down counter DC, and time reporting is performed the number of times on the hour.

Note that the contents of the counter _CT2 are adjusted in advance to the display time.

By the way, in the above embodiment, a doll that performs a bell-ringing motion is described as a movable decoration, but the present invention is not limited to this. For example, a small bird may be used that moves its wings, beak, etc., and the sound may be electronically generated in synchronization with the movement of its beak.

As described above, according to the present invention, the timer circuit is operated by the output of the switch that operates a predetermined time before the movable decorative body performs the pseudo alarm operation, and the output from the timer circuit causes the pseudo alarm to sound. Since an electronic sound is generated in synchronization with the operation, no matter what timing the switch operates, it is possible to reliably synchronize the timing of the pseudo alarm operation and the electronic sound by setting the timer circuit. be.

In addition, when the number of operations of the switch reaches a preset number, the drive output of the motor is stopped after a certain period of time, so when the movable decoration returns to the initial position after the switch is activated, the movable decoration will stop. The movable decorative body can be reliably returned to its original position.

Therefore, for example, if a doll is used to strike a bell, the doll only imitates striking the bell, and the bell, hammer, etc. can be made of plastic and can be made very inexpensively. Also, when used in a cuckoo clock, a bellows becomes unnecessary.
