[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a timepiece in which the main body of a mechanical clock rotates front and back in relation to the performance of a melody, and in particular, it improves upon the invention of Japanese Patent Application No. 1-92998. In Japanese Patent Application No. 1-92998, there is a doll or other ornament on the back side of the clock dial, and when the melody is played, the timepiece body rotates, and this ornament appears in front of the melody. Then, the clock rotates again and the original clock dial faces the front.

[0002]

[Prior art]

 There are many karakuri clocks in which decorative objects such as dolls move when playing a melody. The invention of Japanese Patent Application No. 1-9 2998 described above has been proposed for rotating a watch body.

[0003]

[Problems to be solved by the device]

 The idea of the present invention is to make the rotary timepiece rotate smoothly during rotation.

[0004]

[Means for Solving the Problems]

 This invention will be described with reference to a rotary timepiece according to claim 1. 1, 2, 3, and 4, the main body 1 is provided with a decorative body 4 on the back side 3 of the timepiece dial 2 and is rotated on the base 5.

A means for inputting a trigger signal to the melody IC at the time signal time is, for example, a circuit which outputs a signal at the time signal time of a clock and which serves as a trigger (not shown). The means for rotating the main body 1 through the switching circuit 6 between the audio output and the inverted output of the IC is a device for rotating the main body 1 by driving each output through the switching circuit 6 and driving a motor by the signal. (Not shown).

Further, the main body 1 has means for switching the switching circuit 6 between the front position and the rear position, and the ornamental body 4 on the rear surface of the main body is rotated in the normal direction by the audio output signal of the melody IC, and the switching is performed. The circuit 1 is switched and the main body 1 is stopped, and the main body 1 is rotated until the clock dial 2 is returned to the original front by the signal of the inverted output of the audio output, the switching circuit 6 is switched again and the main body 1 is stopped. To do.

In the rotary timepiece having the above device, the switching circuit 6 uses a latching relay 7. In this example, the magnet M is arranged on either one of the rotating main body 1 and the fixed base 5, and the two reed switches RS1 and RS2 are arranged on the other at 180-degree positions about the rotation axis 8 respectively. The lead switches RS1 and RS2 are devices connected to the latching relay 7 respectively.

A latching relay has two operating coils, and once a signal is input to one coil, the circuit is kept as it is until a signal is input to the other coil. The reed switch is a switch whose circuit is formed by magnetic force.

The reed switch may form a circuit using a Hall element to form a switch.

[0010]

[Action]

 This operation will be described with reference to FIGS. 1, 2, 3 and 4 in the embodiment relating to claim 1 above. The timepiece always faces the front (FIG. 1) and displays the time on the dial. At the time signal time, the trigger signal enters the melody IC and the melody is played. At this time, the switching circuit 6 transmits the audio output to the rotation of the main body 1 (the positional relationship between the reed switch and the magnet is as shown in FIG. 4). When the main body 1 rotates and the magnet M comes to the position of the reed switch RS2 in FIG. 4, the lead switch RS2 operates and the latching relay 7 switches the circuit, and the main body 1 turns the back side decorative body to the front. Stop. But the melody is still playing. The watch remains face-down during the performance. When the melody is finished playing, the audio output stops and the inverted output becomes a signal. Then, through the switching circuit of the relay 7 which has been switched to the front, the main body 1 rotates again, the magnet M stops at the position of the reed switch RS1, and the dial of the timepiece faces the front.

[0011]

【Example】

 In addition to the embodiment relating to claim 1, the following examples will be given. As shown in FIG. 5, a magnet is provided with M1 and M2 at 180-degree positions around the rotary shaft 8 of the main body 1, respectively. The fixed base 5 is provided with one reed switch RS, which is connected to the stepping kig relay 9. A stepping relay that switches the circuit every 1 step is adopted. The relay 9 switches the circuit each time the magnets M1 and M2 make a half rotation, and operates in the same manner as in the previous embodiment.

Further, instead of the latching relay or the stepping relay, a circuit composed of a semiconductor such as an SCR or a transistor can be adopted.

Further, instead of the magnet and the circuit that operates by this magnetic force, an LED or a photocell may be used. In this case, the LED is preferably turned on only when the main body 1 is rotated. This circuit can also be easily constructed using audio output.

Whether magnetic force is used or light is used, the same effect can be obtained even if a magnet is provided on either one of the watch body and the base, or a light emitting element is provided on the other with a switch that acts by magnetic force, or a light receiving element. To do.

[0015]

[Effect of device]

 According to this invention, when the melody starts to play at the time of the time signal, the main body of the watch turns to the back, the decorative body provided on the back side faces to the front, and at the same time when the performance ends, the character plate of the watch reappears. Appears. It has a great effect as a karakuri clock that attracts people's eyes to the clock that rotates when playing a melody to give surprise. Furthermore, there is potential for future application such as the decorations moving according to the melody.

If the rotation position of the timepiece main body is controlled by magnetic force or light without using a cam as a device for switching the switching circuit for audio output, the rotation of the timepiece is smooth.
