Description of the Related Art A mechanical energy generated by a spring is converted into electric energy by a generator, and a rotation control means is operated by the electric energy to control a current value flowing through a coil of the generator. 2. Description of the Related Art An electronically controlled mechanical timepiece that accurately displays the time by accurately moving a hand fixed to a wheel train is known.

FIGS. 8 and 9 show this electronically controlled mechanical timepiece.
A timepiece having a structure as shown in FIG.

[0004] This electronically controlled mechanical timepiece is a mainspring 1
a, a barrel wheel 1 having a barrel gear 1b and the like. The barrel wheel 1 is inserted through a support member provided on a base plate 2 serving as a base plate, and is fixed by a square hole screw 5.

[0005] The rotation of the barrel gear 1b is accelerated through a second wheel & pinion 7 to a sixth wheel & pinion 11, which are supported by a main plate 2 and a train wheel receiver 3 which is an upper plate opposed to the main plate 2. . At this time, the center wheels 7 to 11 are provided on different axes, respectively, and are arranged at positions not overlapping with the coil winding portions 35 and 36 of the coil blocks 31 and 32.
To form a torque transmission path. A second support 4 is provided between the main plate 2 and the train wheel receiver 3.

This electronically controlled mechanical timepiece has a generator 30. The generator 30 includes the rotor 12 and the coil blocks 31 and 32. Rotor 12
Has a rotor pinion 12a, a rotor magnet 12b, and a rotor inertial disk 12c.

The coil blocks 31 and 32 include stators 37 and 38 disposed adjacent to the rotor 12, respectively.
Core 3 provided continuously with the stators 37 and 38
3, 34, coil winding portions 35, 36 formed by coil wires wound around the cores 33, 34, and core magnets provided continuously with the cores 33, 34 and connected to each other. It is configured to include conductive portions 37b and 38b.

In assembling an electronically controlled mechanical timepiece having such a structure, the base plate 2 is set on a predetermined mounting table or the like, and then the generator 30, the wheel wheels 7 to 11 and the train wheel receiver 3 are mounted. , Which are sequentially attached to the main plate 2 and assembled.

The structure of the generator 30 is the same as that of the motor. For this reason, even in a quartz timepiece having a motor and a train wheel, parts constituting the motor such as a rotor, a stator, and a coil (core), and a train wheel driven by the motor are assembled to a main plate, and further a train wheel receiver is attached. Had been assembled.

[0010]

The causes of such electronically controlled mechanical timepieces and quartz timepieces are as follows: disconnection of the coil portion of the generator or motor, coil shortage, running out of oil at the rotor shaft support, There is much adhesion of dust etc. around the rotor. If these troubles occur, the hands will stop or be delayed, so it is necessary to disassemble the watch and maintain the generator and motor parts. is there.

That is, in the conventional generator 30 and motor, the sixth wheel & pinion 11 and the rotor pinion 12a meshing with the sixth wheel & pinion 11 are incorporated in the stator 37, 38 on the side of the train wheel receiver (upper plate) 3.

For this reason, a failure occurs due to the above-mentioned cause, and the generator 30, the stators 37 and 38 of the motor, and the coil winding 3
When it is necessary to remove 5, 36, the back cover of the watch was removed, the train wheel receiver (upper plate) 3 arranged on the back cover side of the movement was removed, and the sixth wheel 11 and the rotor 12 were removed in this order. Unless later, the stators 37 and 38 and the coil winding portions 35 and 36 cannot be removed, and there is a problem that the disassembly and assembly are troublesome and take a lot of time, so that maintenance is difficult. .

An object of the present invention is to provide an electronic device and a timing device that can be easily disassembled and assembled and maintenance is easy.

[0014]

An electronic apparatus according to the present invention includes an electromagnetic converter having a magnetic circuit composed of at least one or more rotors, one or more stators, and one or more coils. In an electronic apparatus comprising a mechanical energy transmitting means engaged with a machine, and a base plate and an upper plate supporting the rotor and the mechanical energy transmitting means, an engagement position between the rotor and the mechanical energy transmitting means is determined by the electromagnetic conversion. The stator is disposed closer to the base plate than the stator of the machine.

The mechanical energy transmitting means is constituted by, for example, a train wheel. In this case, the engagement position between the rotor and the mechanical energy transmitting means is a meshing position between the gear wheel of the wheel train and the rotor pinion.

According to the present invention, the stator of the electromagnetic converter including the generator and the motor is positioned at the engagement position between the rotor of the electromagnetic converter and the mechanical energy transmitting means such as the wheel train (for example, the rotor or the like). It is located closer to the upper plate than the gear wheel of the wheel train), so even if a failure occurs, removing the upper plate allows you to remove the rotor and mechanical energy transmission means (such as the sixth wheel). In addition, a coil winding portion wound around a stator or a core of a generator or a motor can be removed. As a result, the disassembly and maintainability of the electronic device can be improved, and the number of disassembly and man-hours can be reduced, so that the generator or motor coil, which has relatively many failure causes, can be easily replaced or repaired.

Further, it is preferable that a stator and a coil of the electromagnetic converter are attached to the upper plate.

According to the present invention, since the stator and the coil (coil winding portion) of the electromagnetic converter can be removed at the same time by removing the upper plate, replacement or repair of the coil, which has a relatively large number of causes of failure, is further improved. Easier,
Maintenance work can be greatly reduced.

Further, the upper plate is located on the opposite side of the engagement position between the rotor and the mechanical energy transmitting means (the side opposite to the surface of the upper plate facing the base plate, and the back cover side in the case of a watch). May be provided with a rotating weight capable of transmitting mechanical energy to the mechanical energy transmitting means.

If such a rotary weight is provided, an automatic power generation mechanism can be configured by setting the rotor of the generator (electromagnetic converter) to rotate by the torque of the rotary weight. Further, by setting the mainspring, which is a mechanical energy source, to be wound by the rotating force of the rotating weight, an automatic winding mechanism can be configured.

Further, since the stator of the electromagnetic converter is arranged on the upper plate side from the position where the rotor pinion meshes with the gears of the wheel train, the entire wheel train can be efficiently reduced in size, and the rotating weight can be reduced. Even if provided, the overall thickness can be reduced.

Further, it is preferable that the upper plate is divided into a plurality. More preferably, it is preferable to be configured with a plurality of upper plates that support the electromagnetic converter portion and upper plates that support other wheel trains and the like. For example, the upper plate is placed at least in a position that does not interfere with the first receiving body that supports the rotor of the electromagnetic converter and that is formed separately from the first receiving body and that removes at least the stator and the coil of the electromagnetic converter. What is necessary is just to comprise with the several 2nd with the arrange | positioned 2nd receiver.

According to this structure, when performing maintenance on the electromagnetic converter part having the most problems, it is possible to remove only the upper plate (first receiving body) corresponding to the electromagnetic converter part and perform maintenance. Since it is not necessary to remove all upper plates, disassembly and maintenance can be improved. In particular, if there is no need to remove the upper plate (second receiving body) supporting the mechanical energy transmission means such as the train wheel, mixing of dust and the like into the train wheel and mortising when attaching each wheel wheel to the upper plate are possible. It is also possible to prevent a trouble (secondary adverse effect) in which a steel count wheel not supported by the train wheel receiver is tilted or magnetized by the magnetic force of the rotor magnet.

Further, if the upper plate is divided into a plurality of parts, even if the rotating weight is provided, the rotating weight can be moved to a position where it does not overlap with the upper plate (first receiving body) supporting the electromagnetic transducer portion. For example, the upper plate (first receiving body) can be removed without removing the rotating weight, so that the maintainability can be further improved.

Further, it is preferable that the rotor has an inertial disk, and the inertial disk is disposed closer to the upper plate than the engagement position between the rotor and the mechanical energy transmitting means.

If the inertial disk is provided, especially when the rotor of the electromagnetic converter rotates at a constant speed, the rotation frequency can be further stabilized. Further, when the electromagnetic converter is a motor, the rotation frequency of the sweep hand movement can be stabilized.

Further, when the rotor is removed due to a failure or the like, it is not necessary to remove the mechanical energy transmission means (for example, a sixth wheel engaged with the rotor), so that disassembly and assembly are facilitated, and the maintainability can be further improved.

According to a second aspect of the invention, there is provided a timing device comprising the electronic device according to any one of the first to sixth aspects and a time display device for displaying time.

According to the present invention as described above, it is possible to provide a timing device that facilitates disassembly and assembly and facilitates maintenance.

At this time, as the timekeeping device of the present invention, the electromagnetic converter is a generator, and a rotation control device that is driven by electric energy supplied from the generator to control the rotation cycle of the generator is provided. It may be an electronically controlled mechanical timepiece provided.

According to the present invention, it is possible to provide an electronically controlled mechanical timepiece that is easy to disassemble and assemble and easy to maintain.

The electronically controlled mechanical timepiece includes a mainspring 1a as a mechanical energy source, a speed increasing wheel train (each wheel wheel 17 to 21) as an energy transmission device for transmitting the torque of the mainspring 1a to the generator 30; It has hands (minute hands, second hands, and hour hands, not shown) that are time display devices connected to the speed increasing train trains 17 to 21 to display time.

The generator 30 is driven by the mainspring 1a through the speed increasing wheel train to generate induced power and supply electric energy. The AC output from the generator 30 is boosted and rectified through a rectification circuit 61 including step-up rectification, full-wave rectification, half-wave rectification, transistor rectification, and the like, and is supplied to a power supply circuit 60 including a capacitor and the like.

The output Q12 at the twelfth stage of the frequency dividing circuit 52 is output as the 8 Hz reference signal fs.

The rotation detection circuit 53 detects the rotation based on the output of the generator 30 and outputs a rotation detection signal FG1.

The braking control circuit 55 compares the rotation detection signal FG1 of the rotation detection circuit 53 with the reference signal fs from the frequency dividing circuit 52, and outputs a signal CH for adjusting the speed of the generator 30 according to the difference. 30.

The speed control method of the generator 30 is, for example, as follows.
The brake control is performed by applying a short brake by closing the loop between the terminals of the generator 30 and controlling the brake by connecting a variable resistor or the like to the generator 30 and changing the current value flowing through the coil of the generator 30. It is configured.

In this embodiment, the generator 3
In order to perform maintenance of the zero part, the rotating weight 25 and the transmission receiver 48 are removed, and then the first
Only the receiver 23A needs to be removed. Thereby, the stators 37 and 38 and the cores 33 and 34 can also be removed, and the maintenance work of the generator 30 can be performed.

When the maintenance is completed, the stator 3
What is necessary is just to attach the 1st receiver 23A to which 7, 38 and the cores 33, 34 were attached.

According to the present embodiment, the following effects can be obtained.

1) Since the meshing position between the rotor pinion 22a of the generator 30 and the gear wheel of the sixth wheel & pinion 21 is located closer to the main plate 2 than the stators 37 and 38 of the generator 30, a failure occurs. , The train wheel receiver 23A is removed, and the coil winding portions 35, 3 of the generator 30 having relatively many failure causes are removed.
6 can be checked, and operations such as coil replacement of the coil winding portions 35 and 36 can be performed. At this time, since the sixth wheel & pinion 21 and the rotor 22 may be left attached to the main plate 2, the disassembling and assembling operations are facilitated, and the maintainability can be improved.

2) Since the stators 37 and 38 and the cores 33 and 34 of the generator 30 are attached to the wheel train receiver 23A, the generator 30 is removed by removing the wheel train receiver 23A.
Of the stators 37 and 38 and the cores 33 and 34 can be simultaneously removed. Therefore, the stator 3 of the generator 30
When it is necessary to remove 7, 38, the stator is
First, as in the case of being mounted on
After the A is removed, it is not necessary to perform the work such as removing the stators 37 and 38 from the main plate 2 twice, so that the disassembly, the assembling property, and the maintenance property can be improved.

3) The engagement position between the rotor pinion 22a and the gear of the sixth wheel & pinion 21 is determined by the stators 37 and 38 of the generator 30.
, The rotor inertia disk 22c can be disposed below, and the center of gravity of the rotor 22 itself when the rotor 22 is assembled is lower. As a result, the balance of the rotor 22 is improved and stabilized, and mortise at the time of assembly is facilitated, so that the assemblability is improved. In particular, since the inertial disk 22c is closer to the base plate 2 (below) than the rotor pinion 22a, the center of gravity is located lower and the stability is improved.

4) Since the rotor pinion 22a is disposed closer to the base plate 2 than the stators 37 and 38 of the generator 30, the gear wheel of the sixth wheel & pinion 21 and the fifth wheel & pinion 20 which mesh with the rotor pinion 22a are also arranged in this order. The fourth wheel 19 can be placed on the main plate 2 side.
Can be arranged on the uppermost layer on the side of the train wheel receiver 23. As a result, the fourth wheel & pinion 19 can be provided above the barrel wheel 1, and without reducing the diameter of the fourth wheel & pinion 19,
In addition, it can be arranged so as to overlap the sixth wheel & pinion 21 in a plane. Therefore, it is not necessary to increase the number of wheel train stages, and the whole can be miniaturized. Further, since the entire wheel train can be efficiently reduced in size, even if the rotary weight 25 is provided, an increase in the thickness of the entire movement can be suppressed, and a thin timepiece that can be automatically wound can be configured.

5) The train wheel receiver 23 is composed of the first and second receivers 2
3A and 23B, the first receiving body 23A is arranged to receive a portion including the rotor 22 and the magnetic conducting parts 37b and 38b of the generator 30, and the second receiving body 23B is arranged to receive most of the wheel train. Therefore, for example, when there is a failure such as a failure on the generator 30 side, only the first receiver 23A may be removed and repaired. In this case, the second receiving body 23B on the wheel train irrespective of the defective portion may be left as it is, and it is not necessary to remove the tenon of each of the wheel 17-1 of the second receiving body 23B. No problem. Therefore, the assemblability and the maintainability can be improved. In addition, it is possible to prevent secondary adverse effects caused by removing the second receiving body 23B on the wheel train irrelevant to the defective portion.

6) The rotor 22 (seventh wheel) needs a rotor inertia disk 22c having a predetermined outer diameter in order to obtain stable inertia. Therefore, the rotor inertia disk 22c having a large outer diameter can be provided between the fifth wheel & pinion 20 and the sixth wheel & pinion 21 without increasing the number of wheel trains. Since it is not necessary to increase the number of gear train stages, the load loss can be reduced, and since the load loss is reduced, if the time is set to be the same as the conventional duration, the thickness of the barrel diameter is reduced. be able to. Also, since the number of gear train stages is reduced, the overall layout is small,
Thinning has become possible.

FIG. 5 shows an electronically controlled mechanical timepiece according to a second embodiment of the present invention.

In the present embodiment, the first embodiment differs from the first embodiment in that the wheel train receiver 23 is divided into first and second receiving bodies 23A and 23B. It was done.

Therefore, the same or corresponding parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted or simplified. Also, the part corresponding to FIG.
The description is omitted because it is the same as in the first embodiment.

In the second embodiment as well, the same effects as those of the first embodiment except for the above 5) can be obtained.

In each of the above embodiments, the inertia disk 22c of the rotor 22 is disposed closer to the base plate (base plate) 2 than the position of the gear wheel of the sixth wheel & pinion 21, which meshes with the rotor pinion 22a. A rotor pinion 22a is provided below the inertial disk 22c (on the side of the ground plate 2).
The gear of the sixth wheel & pinion 21 is meshed with a.
That is, the position of the inertial disk 22c is located closer to the train wheel receiver 23 (upper plate side) than the meshing position of the pinion 22a and the gear of the sixth wheel & pinion 21.

In such an embodiment as well, the first
In addition to obtaining the same effects as the embodiment, when the rotor 22 needs to be removed due to a failure or the like, the sixth wheel & pinion 21 does not need to be removed, so that disassembly and assemblability are further facilitated,

Belts), pulleys, chains and sprocket wheels, racks and pinions, cams, and the like may be used, and may be set as appropriate according to the type of electronic equipment to which the present invention is applied.

Further, the time display device is not limited to the hands, but may be a disk, a ring or an arc.

When it is not necessary to rotate the generator at a constant speed as in the case of an electronically controlled mechanical timepiece, for example when it is used as a power supply, the rotation speed of the rotor is controlled by the rotation control device depending on, for example, the load condition. It may be changed appropriately, and it is not necessary to provide a rotation control device, that is, not to control the speed of the rotor of the generator. Even when the speed of the rotor is not controlled, the energy of the mechanical energy source can be stored in the form of electrical energy in a secondary battery or the like, so that an electronic device with a long duration can be provided.

[0088]

As described above, according to the electronic device and the timing device of the present invention, the position of the stator of the electromagnetic converter is determined by the engagement position between the rotor of the electromagnetic converter and the mechanical energy transmitting means such as the train wheel. (For example, the position where the rotor meshes with the gears of the wheel train and the gears of the wheel), the upper plate is disposed, so if the upper plate is removed, the rotor and mechanical energy transmission means (such as the sixth wheel) can be removed. It is possible to remove a coil or the like wound on the stator or the core of the electromagnetic converter. As a result, if a minor failure (failure caused only by the coil and stator) occurs, it can be repaired by removing only the upper plate. Repair can be easily performed.
