It has become. A first output shaft 31 of a biaxial motor 30 is attached to the pinion 23, and the pinion 23 rotates integrally with the first output shaft 31. The outer peripheral surface of the motor housing of the biaxial motor 30 is fixed to the inner peripheral surface of the rotating unit 8. At this time, the biaxial motor 30 is fixed by fitting the stopper ring 34. Therefore, the internal gear 14 formed on the inner peripheral surface of the rotating portion 8 is formed except for this fixed portion.

  A first rotor and a second rotor in which a field magnet for generating a magnetic field and separate coils for generating a driving force with respect to the magnetic field are wound inside the motor housing of the biaxial motor 30. And the first rotor is provided with a first output shaft 31, and the second rotor is provided with a second output shaft 32. The first rotor rotates in the forward and reverse directions.

  An eccentric weight 33 as shown in FIG. 2 is attached to the tip of the second output shaft 32 described above, and the eccentric weight 33 rotates integrally with the second rotor. Further, the eccentric weight 33 is arranged inside the rotating portion 8.

  As described above, the second planetary carrier including the bearing 15, the internal gear 14, a part of the rotating shaft 16, the liner 21, the first planetary carrier 20, the planetary gear 20b,. 22, a planetary gear 22b,..., A pinion 23, a biaxial motor 30 and an eccentric weight 33 are arranged, and among them, a first planet carrier 20 including a bearing 15, an internal gear 14, a liner 21, and a rotating shaft 16, a planetary gear. 20b, the second planet carrier 22 including the sun gear 22c, the planet gears 22b, and the pinion 23 reduce the rotational speed of the first rotor and rotate the cylindrical portion 9a with respect to the rotating portion 8.

  As a second embodiment, as shown in FIG. 3, there is one in which the second housing 7 slides 180 ° relative to the first housing 4 to open and close the foldable portable device 1.

  In this case, the mechanism of the hinge part similar to the first embodiment, that is, the cylindrical part 9a and the rotating part 8 are perpendicular to the surface on which the button of the first housing 4 is arranged as shown in FIG. Will be placed.

Next, the operation of this embodiment will be described.
When the first output shaft 31 of the biaxial motor 30 rotates with respect to the rotating unit 8, the pinion 23 attached to the tip of the first output shaft 31 transmits the rotational force to the planetary gears 22b. The planetary gears 22b... Rotate by the rotational force with the protrusions 22a. The second planet carrier 22 is rotated by the rotation and revolution of the planetary gears 22b... And the sun gear 22c fixed integrally with the second planet carrier 22 is also rotated. The sun gear 22c transmits the rotational force to the planetary gears 20b. Similar to the second planet carrier 22, the first planet carrier 20 is rotated by the rotation and revolution of the planetary gears 20 b..., And the rotating shaft 16 fixed integrally with the first planet carrier 20 is also rotated.

  As the rotary shaft 16 rotates, the male coupler 13 fixed to the tip thereof rotates. As the male coupler 13 rotates, the female coupler 11 including the concave portion 12a in which the convex portion 12b formed in the male coupler 13 is received rotates. By rotating the female coupler 11, the cylindrical portion 9 a fixed via the female coupler 11 and the biasing spring 10 rotates with respect to the rotating portion 8. Naturally, when the first rotor of the biaxial motor 30 rotates in the direction opposite to the above with respect to the rotating part 8, the cylindrical part 9 a rotates in the direction opposite to the above with respect to the rotating part 8.

  Thus, since the cylindrical portion 9a is freely rotatable with respect to the rotating portion 8, when an instruction to open or close the second housing 7 with respect to the first housing 4 is input from the operation button 2 to the control portion. The control unit controls the first rotor of the biaxial motor 30 to rotate the first rotor in the direction corresponding to the instruction. As described above, since the cylindrical portion 9a is rotated by the rotational force of the first output shaft 31 with respect to the rotating portion 8, the second casing 7 to which the rotating portion 8 is fixed is naturally the cylindrical portion 9a. Is driven to open and close with respect to the fixed first casing 4. The user can open and close the foldable mobile phone 1 by the rotation of the first rotor. Moreover, even if it is manual, the 2nd housing | casing 7 is opened and closed with respect to the 1st housing | casing 4 naturally with the said clutch mechanism.

  On the other hand, since the eccentric weight 33 is attached to the tip of the second output shaft 32 of the biaxial motor 30, when the incoming call is received by the foldable mobile phone 1, the control unit sets the biaxial motor as the silent mode. The eccentric weight 33 is rotated by controlling the second rotor 30. Vibration is applied to the foldable mobile phone 1 by the rotation of the second rotor, and the user is notified of the incoming call by the vibration.

  As described above, the biaxial motor 30 is mounted on the foldable mobile phone 1, the second housing 7 is driven to open and close with respect to the first housing 4 by the rotational force of the first output shaft 31, and the second output Since the configuration is such that the eccentric weight 33 is rotated by the rotational force of the shaft 32, a single-axis motor that has been conventionally provided for separately rotating the eccentric weight 33 does not have to be provided inside the folding cellular phone 1. A good configuration can be obtained. Further, it is possible to effectively use the space inside the rotation support portion 9 and the rotation portion 8 that has been conventionally not used effectively inside the foldable mobile phone 1.

  Therefore, according to the present embodiment, a single-axis motor that has conventionally been separately provided for rotating the eccentric weight need not be provided inside the case of the foldable portable device 1 and is effectively used. By arranging the biaxial motor 30 in the space inside the rotation support portion 9 and the rotation portion 8 that have not been provided, the space where the uniaxial motor has been disposed can be left empty or omitted, and Since the space inside the cylinder of the moving support unit 9 or the rotating unit 8 can be effectively used, a space for installing a device for operating a new function can be secured, or a more compact folding portable device can be provided. There is an effect that it can be provided.

  In addition, as described above, since the area where the single-axis motor is conventionally arranged can be made an empty area, the size of the folding cellular phone 1 can be reduced by the volume of the empty area inside the folding cellular phone 1. Alternatively, it is possible to easily reduce the thickness.

  In the present embodiment, the planetary carrier has a two-stage configuration including the first and second planet carriers 20 and 22, but is not limited to this. It is good also as composition, such as a formula.

  Furthermore, in the present embodiment, the foldable mobile phone 1 has been described as an example. However, the foldable mobile phone 1 may be a foldable mobile device including two general housings, a first housing and a second housing. It can be applied to notebook personal computers, electronic dictionaries, PDAs, and the like.
