Description

[Detailed Description of the Invention] This invention relates to a timepiece device, and particularly to a timepiece device using a resonator as a driving source, such as a quartz clock or a tuning fork clock.

A typical crystal clock includes an electronic circuit block including a crystal oscillator, a transistor motor rotated by the output of the electronic circuit block, and a clock mechanism block driven by the transistor motor.

In conventional quartz watches, the electronic circuit block and the coil part of the transistor motor were connected by soldering with lead wires, or the coil was fixed to the board of the electronic circuit block.

Therefore, assembly was complicated and repair was difficult.

In particular, when the coil of a transistor motor breaks, there is a problem in that the entire electronic circuit block must be replaced.

Therefore, the object of this invention is to provide a timepiece device that is easy to assemble and repair.

An exploded perspective view of one embodiment of the timepiece device of this invention is shown in FIG.

In the figure, this clock device has a mechanism block A and a motor B.
and an electronic circuit block C.

A motor B is attached to the mechanism block A, and the motor B is composed of a magnetized rotor 1 and a coil 2.

The state of engagement between the coil 2 and the upper base plate 7 is illustrated in FIG.

That is, the coil 2 is fixed on the plastic plate 10, and terminal blades jl, t2, and t3 are provided on the lower side of the plastic plate 10, and the winding start end, middle part, and winding end of the coil 2 are connected to each of them.

This plastic plate 10 is detachably fixed to the upper base plate 7.

Referring again to FIG. 1, the rotor 1 is pivoted to the upper base plate 7 above the coil 2.

A worm 3 is provided on the rotor 1 and rotates, and the rotation is sequentially transmitted to a worm wheel 4, a second hand wheel 5, and a transmission wheel 6.

These rotation mechanisms are held between the lower base plate 8 and the upper base plate 7.

On the other hand, the printed circuit board 9 of the electronic circuit block C has the terminal blade t1 of the coil 2. Terminal receiving blades T, , T2ε and T3 are provided which are respectively adapted to t2 and t3, and the coil 2 and the electronic circuit block C are detachably connected.

FIG. 3 is a circuit diagram showing the connection state between the motor B and the electronic circuit block C.

That is, the coil 2 of the motor B has a detection coil L1 and a drive coil L2, and the terminal blade t1 at the winding start end is connected to the terminal receiving blade T.
1, the terminal blade t2 at the intermediate portion is connected to the terminal receiving blade T2, and the terminal blade t3 at the end of the winding is connected to the terminal receiving blade T3.

Furthermore, the electronic circuit block C includes an oscillation circuit 11 and a frequency dividing circuit 1.
The motor B and the transistor 13 constitute a transistor motor.

As mentioned above, the clock device of this invention has a mechanism block,
A motor rotor is pivotally attached to the mechanism block, a coil surrounds and rotates the motor rotor, and the coil is fixed and a terminal blade of the coil is protruded, and the coil is removably attached to the mechanism block. The electronic circuit includes a plastic plate and an electronic circuit block having a terminal receiving blade detachably connected to the terminal blade and supplying electrical energy to the motor coil to rotate the motor rotor. There is no need to solder the lead wires between the block and the motor coil section, and the mechanism block, motor coil section, and electronic circuit block can be disassembled separately, making it easy to assemble and disassemble the clock device. Advantages arise in that assembly, aging, inspection, etc. can be carried out.
