Abstract

PURPOSE:To simplify the constitution and to generate sound synchronizing with the movement of a movable decorative body by generating electronic sound by the output of a switch interlocking with the movement of the decorative body. CONSTITUTION:When an alarm time comes, a switch SA is closed, one pulse is generated from a generator W1, the contents of a down-counter DC and a setting circuit ST are preset, and an FF-F1 is set. As a result, a motor ML is rotated, and a movable decorative body A is driven. A switch S is closed by this driving, one pulse is sent out from a generator W2, the contents of DC are counted by one, and a timer TM2 is operated. After a constant interval of time, an output is generated by synchronizing with operation of the decorative body from TM2 to set an F3. As a result, an output is generated from a control circuit AL, and the sound of a bell by the electronic sound is generated from a sounding device SP.

Description

[Detailed description of the invention] The present invention relates to a watch 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, for dolls to strike bells, the bell and the hammer used to strike the bell must be made of metal, and the supporting structure of the bell is complicated.
It was disadvantageous 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 decorative body.

An embodiment of the present invention will be described below based on the drawings. 1st
In the figure, Q is the oscillator, D is the frequency divider, and DR is the motor y.
The drive circuit sT is a setting circuit that presets the number of alarm sounds. TM.

TM21't tie-q circuit, F, , F3 are flip-flop circuits, Wl, Wl are one-shot pulse generators,
GI and G2 are gate circuits, and ■ is an impark. ,
AL is an alarm control circuit, and SU 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, a doll holding a hammer is used as the movable decoration A, and this swings as the motor ML rotates to strike a bell (not actually strike it).

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 sound stop switch.

Next, the operation will be explained. When the alarm time arrives, switch SA closes and one-shot pulse generators W, to 1
A pulse is generated, the contents of the down counter DC setting circuit ST are preset, and the flip-flop circuit Fl
is set.

By setting the flip-flop circuit Fl, the motor M
L 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 down counter D.

The contents of the timer circuit TM2 are counted by one and the timer circuit TM2
works. The timer circuit TM2 generates an output after a certain period of time, that is, in synchronization with the movement of the movable ornamental doll tolling the bell, and the flip-flop circuit F3 is set. As a result, outputs are generated from the alarm control circuits A and L, and an electronic bell is sounded by the sounding device. It looks as if the doll actually struck the bell.

The above operation is repeated by rotating the motor ML. When the stop switch SS is closed, the output of the flip-flop circuit F2 is set to 1 by the first pulse from the one-shot pulse generator W2.
Then, the timer circuit TM operates. The flip-flop circuit F is reset by the output from the timer circuit TMI after a certain period of time, and the motor ML is stopped to stop the sound. The time set in the timer circuit TM is set to the time required for the doll to return to its original position after the action of ringing the bell. L, Lr 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 performed, when the content of the down counter Do becomes D, the same operation as when the switch SS is closed is performed by the output thereof, and the ringing is stopped.

Figure 2 shows an example of use in a time signal clock, in which C1Tl is a 60 minute counter, OT2 is an hour counter,
The other configurations are the same as in FIG. 1.

In the above configuration, on the hour, an output is generated from the counter OTI, and the one-shot pulse generator W175\
1 pulse is generated. The contents of the counter CT2 (down counter DCvc) are set to 1 due to the pulse, and the time is reported as many times as the hour is on the hour.

The contents of the navigation counter CT2 are adjusted in advance to the display time.

By the way, in the above embodiment, the hole is not limited to the doll that performs a bell-ringing motion as a movable decoration.
For example, a fully powered Japanese crow with wings and beak may be used, and the sound may be generated electronically in synchronization with the movement of the beak.

As described above, according to the present invention, electronic sound is generated by the output of the switch that is linked to the movement of the movable decorative body, so it is possible to simplify the configuration, and synchronize with the movement of the movable decorative body. Can generate sound.

Therefore, for example, if a doll is used to strike a bell, the doll simply imitates striking the bell, so the bell, hammer, etc. can be made of plastic and can be made very inexpensively. Also, if you use it for a clock, you won't need a figurine.
