  Preferably, the mouse main body includes a placement portion for placing the palm and a pair of operation portions provided in front of the placement portion and operated with fingers of the hand, and the vibration dynamo is below the pair of operation portions. The solar panel is provided in front of the pair of operation units.

  ADVANTAGE OF THE INVENTION According to this invention, the wireless mouse which can generate | occur | produce sufficient electric power for operating can be provided.

It is a figure which shows an example of the wireless mouse which concerns on embodiment of this invention, (a) is a top view, (b) is sectional drawing which follows the Ib-Ib line | wire of Fig.1 (a). It is sectional drawing which shows a vibration dynamo schematically. 1 is a schematic circuit diagram of a wireless mouse according to an embodiment of the present invention.

  Embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

  With reference to FIG. 1, a wireless mouse 1 according to an embodiment of the present invention will be described. In FIG. 1, the direction indicated by the arrow A is referred to as the left-right direction, the direction indicated by the arrow B is referred to as the front, the direction opposite to the arrow B is referred to as the rear, and the direction indicated as the arrow C is referred to as the up-down direction.

  The wireless mouse 1 is used for operating a personal computer, and is a wireless mouse with a built-in power generation function. The wireless mouse 1 includes a mouse main body 10 and a vibration dynamo 20 attached to the mouse main body 10. For the wireless mouse 1, for example, a ball type, an optical type using a light emitting diode, a laser type using a laser beam, an LED type using an LED, or the like is used.

  The outer diameter of the mouse body 10 is the same as that of a general wireless mouse. The mouse body 10 is preferably sized to fit in the user's hand. For example, the vertical (front-rear) dimension is 100 to 140 mm, the horizontal (left-right) dimension is 50 to 90 mm, and the thickness direction (vertical) Direction) is 30 to 60 mm.

  The mouse body 10 includes a placement unit 11 for placing a palm, and a pair of operation units 12 provided in front of the placement unit 11 and operated with fingers of the hand. The placement unit 11 is smoothly curved according to the palm of the hand, for example. The pair of operation units 12 are used for click operation input, and can be operated with, for example, an index finger and a middle finger. A scroll button 14 used when scrolling the screen of the personal computer up and down may be provided at substantially the center of the pair of operation units 12.

  As shown in FIG. 1B, a vibration dynamo 20 having a power generation function is provided below the pair of operation units 12. That is, the vibration dynamo 20 is located in front of the mouse body 10. By providing the vibration dynamo 20 in front of the mouse main body 10, the rear of the mouse main body 10 can be moved left and right using the fulcrum as a fulcrum, so that the vibration dynamo 20 can be moved efficiently. Further, since the vibration dynamo 20 is housed in the mouse body 10, the lateral dimension of the vibration dynamo 20 is smaller than the lateral dimension of the mouse body 10. The vibration dynamo 20 will be described later.

  In front of the pair of operation units 12, a solar panel 30 that receives light such as the sun or an electric light to generate electric power is provided. The solar panel 30 may be located in front of the vibration dynamo 20. By providing the solar panel 30 at a position that does not overlap the pair of operation units 12, the solar panel 30 can efficiently generate power. The solar panel 30 has a horizontally long rectangular shape in plan view. The solar panel 30 extends along the lateral direction of the mouse body 10.

  On the bottom surface 13 of the mouse main body 10, a switch 40 for turning on / off the power is provided. The switch 40 is, for example, a push switch (push button) that is turned on only while being pressed. The switch 40 includes a moving unit 41 and an opening / closing unit 42 that opens and closes a circuit. The moving part 41 has, for example, a T-shape in sectional view, and protrudes downward from the bottom surface 13 of the mouse body 10. By placing and pressing the hand on the mouse body 10, the moving part 41 moves upward, the opening / closing part 42 is conducted, and the switch 40 is turned on. As shown in FIG. 1B, the switch 40 is preferably provided behind the mouse body 10. This is because the rear side of the mouse body 10 is a portion on which the palm of the user is placed and is a portion that is inevitably pressed when the wireless mouse 1 is used. In addition, since the opening / closing part 42 is urged so as to be always turned off, the switch 40 is turned off when a hand is not placed on the mouse body 10. By providing such a switch 40, the switch 40 is turned off in a state where the hand is not placed and pressed on the mouse body 10, so that power consumption can be suppressed.

  Next, the vibration dynamo 20 will be described in detail with reference to FIG.

  The vibration dynamo 20 is accommodated in the cylindrical member 21, the coil 22 disposed on the outer periphery of the cylindrical member 21, and the cylindrical member 21, along the extending direction of the cylindrical member 21. And two movable spherical magnets 23. Closing members 24 are disposed at both ends of the cylindrical member 21. The closing member 24 may be a repulsion member or an elastic member, for example.

  The cylindrical member 21 has a hollow rod shape inside and is open at both ends. The cylindrical member 21 of the present embodiment extends in the left-right direction in FIG. The extending direction of the cylindrical member 21 is provided along the left-right direction of the mouse body 10. Although the cylindrical member 21 will not be specifically limited if it is a magnitude | size which can be accommodated in the mouse main body 21, It is preferable that the horizontal dimension of the cylindrical member 21 of the vibration dynamo 20 shown in FIG. . In addition, the outer shape and inner shape (hollow shape) of the cylindrical member 21 are not specifically limited, A circular shape, a rectangular shape, etc. are mentioned in cross-sectional view. The cylindrical member 21 of the present embodiment has an outer shape and an inner shape that are cylindrical in a sectional view. In addition, the internal diameter (hollow shape diameter) of the cylindrical member 21 of this Embodiment is a little larger than the spherical magnet 23 mentioned later.

  The cylindrical member 21 is made of a nonmagnetic material. The non-magnetic material is a material that is not a ferromagnetic material, and includes a paramagnetic material, a diamagnetic material, and an antiferromagnetic material. Examples of the non-magnetic material include metals such as aluminum and synthetic resins such as plastic.

  A coil 22 is wound around the outer periphery of the cylindrical member 21. For this reason, the cylindrical member 21 also serves as a bobbin for the coil 22. The coil 22 of the present embodiment is provided on a part of the outer periphery of the cylindrical member 21. Specifically, the coil 22 is attached to a substantially central portion of the cylindrical member 21 in the left-right direction. The coil 22 is, for example, a solenoid coil. The coil 22 may be provided on the entire circumference of the cylindrical member 21 or may be provided in a separated region on the outer circumference of the cylindrical member 21.

  Two spherical magnets 23 are provided inside the cylindrical member 21 so as to be movable along the extending direction of the cylindrical member 21 (the left-right direction of the arrow A in FIG. 1). The two spherical magnets 23 are attracted to each other only by the mutual attractive force, and are always in contact with each other.

  The two spherical magnets 23 are permanent magnets and are magnetized so as to have a hemispherical N pole and S pole. The magnetization (magnetization) method is not particularly limited. For example, there is a method in which a magnet material is fixed at the center of the air-core coil, a pulse high current is passed, and magnetization is performed in the axial direction. The material of the magnet is not particularly limited, but it is preferable to use a Nd—Fe—B sintered magnet from the viewpoint of showing a high magnetic force. In addition, the spherical shape means that the outer shape is spherical, and includes those in which the inside is hollow.

  The spherical magnet 23 is not particularly limited as long as the spherical magnet 23 can freely reciprocate inside the cylindrical member 21, but the specific size of the outer diameter of the spherical magnet 23 of the vibration dynamo 20 shown in FIG. -10 mm. In the present embodiment, the sizes of the two spherical magnets 23 are substantially the same, but may be different.

  As described above, the coil 22 is disposed on the outer periphery of the cylindrical member 21. Further, the two spherical magnets 23 are attracted to and in contact with each other. For this reason, the two spherical magnets 23 reciprocate simultaneously along the extending direction of the cylindrical member 21 inside the cylindrical member 21. In other words, the two spherical magnets 23 slide between the closing members 24. Since the two spherical magnets 23 reciprocate so as to pass through the coil 22 disposed on the outer periphery of the cylindrical member 21, the magnetic flux lines generated from the two spherical magnets 23 are orthogonal to the coil 22. At that time, an induced current is generated as an induced electromotive force. Since the two spherical magnets 23 repeatedly enter and exit the coil 22, an alternating current is generated in the coil 22. By using two spherical magnets 23, compared with the case of using one spherical magnet 23, the magnetic force can be increased and more current can be generated.

  Referring to FIG. 3, wireless mouse 1 includes vibration dynamo 20 described above, rectifier circuit 51, solar panel 30, charging circuit 52, circuit opening / closing switch 40, and mouse circuit 50. The charging circuit 52 is preferably connected to a capacitor 53 that stores electric power. Capacitor 53 used in the present embodiment can store up to 2.5 V, for example. The vibration dynamo 20, the rectifier circuit 51, the charging circuit 52, the capacitor 53, and the mouse circuit 50 are accommodated in the mouse body 10, and the solar panel 30 and the moving part 41 of the switch 40 are exposed from the mouse body 10.

  The rectifier circuit 51 is provided at one end of the coil 22 and rectifies an alternating current generated in the coil 22. The charging circuit 52 charges the direct current converted by the rectifying circuit 51. For the charging circuit 52, for example, an electric double layer capacitor is used. The mouse circuit 50 is electrically connected to the vibration dynamo 20 and outputs position information to a personal computer. That is, the mouse circuit 50 detects the position information (coordinates) of the wireless mouse 1 and outputs the detected position information to the personal computer.

  The switch 40 is provided in the middle of the charging circuit 52 and the mouse circuit 50. The switch 40 is operated by a user to switch conduction / non-conduction (ON / OFF) of the mouse circuit 50. In the state where the switch is OFF, when the wireless mouse 1 is vibrated, the current generated by the vibration dynamo 20 is stored in the capacitor 53 via the charging circuit 52. Therefore, according to this embodiment, if the charging circuit 52 is charged, the wireless mouse 1 can be used continuously by turning on the switch 40 without moving the vibration dynamo 20 to the left and right. it can.

  Further, when the solar panel 30 is provided, the solar panel 30 can generate a current without causing the wireless mouse 1 to vibrate. Therefore, in the state where the switch 40 is OFF, the current generated in the solar panel 30 can be charged in the charging circuit 52, so that sufficient power can be generated to operate the wireless mouse 1.

  In addition to the switch 40 described above, an auxiliary switch may be provided between the charging circuit 52 and the switch 40. The auxiliary switch is operated by the user in the same manner as the switch 40, and switches between conduction / non-conduction of the mouse circuit 50, but is preferably a slide switch that is operated by sliding a knob. The auxiliary switch can be made continuous by sliding it to ON, and can be made non-conductive continuously by sliding it to OFF. By providing such an auxiliary switch, the mouse circuit 50 can be kept in a conductive state or a non-conductive state regardless of whether the wireless mouse 1 is operated, as in a general wireless mouse.

  Next, the operation of the wireless mouse 1 according to the present embodiment will be described with reference to FIGS.

  First, a hand is placed on the placement part 11 of the wireless mouse 1, the moving part 41 of the switch 40 is moved upward, the moving part 41 and the opening / closing part 42 are brought into contact, and the switch 40 is turned on. Make it conductive. The mouse body 10 of the wireless mouse 1 is held and reciprocated along the arrow A in FIG. Thereby, inside the cylindrical member 21, the two spherical magnets 23 reciprocate along the extending direction of the cylindrical member 21. Since the two spherical magnets 23 reciprocate so as to pass through the coil 22 arranged on the outer periphery of the cylindrical member 21, the magnetic flux lines generated from the two spherical magnets 23 are orthogonal to the coil 22, At that time, an induced current as an induced electromotive force is generated. Since the two spherical magnets 23 repeatedly enter and exit the coil 22, an alternating current is generated in the coil 22.

  The alternating current generated in the coil 22 is transmitted to the rectifier circuit 51 via wiring (not shown) connected to both ends of the coil 22. Full-wave rectification is performed by the rectifier circuit 51 to rectify an alternating current into a DC power source, and is charged by the charging circuit 52. The charged current is transmitted to the mouse circuit 50 through the switch 40. The mouse circuit 50 is driven (operated) by the supplied current and outputs position information to the personal computer. In this way, the user can use the wireless mouse 1.

  Since a general mouse is not so large as described above, when the vibration dynamo 20 is accommodated in the mouse body 20, the size of the vibration dynamo 20 is limited. Can not. For this reason, as a result of earnest research, the present inventors have found that the magnetic force can be increased and more current can be generated by using two spherical magnets 23. Thereby, although the wireless mouse 1 according to the present embodiment is a small size like a general mouse, it is possible to generate sufficient power for operating the wireless mouse 1.

  Moreover, since the solar panel 30 is attached to the surface of the mouse body 10 in addition to the vibration dynamo 20, even when the switch 40 is in the non-use state and the switch 40 is OFF, the current is always charged as long as light is irradiated. be able to. Thereby, it is possible to generate sufficient power for operating the wireless mouse 1.

  By providing the solar panel 30 in front of the pair of operation units 12, the solar panel 30 is not covered with the user's finger even while the user is operating the wireless mouse 1. As a result, the solar panel 30 can efficiently generate power while the wireless mouse 1 is being operated or not being operated.

  When operating the wireless mouse 1, the user places the palm of the hand (carpal part) on the desk, places the palm on the placement unit 11, and places the finger of the hand on the operation unit 12. Accordingly, by providing the vibration dynamo 20 in front of the mouse body 10, the wireless mouse 1 can be moved left and right with the base portion of the user's hand as a fulcrum, so that the vibration dynamo 20 can be efficiently moved to the left and right. it can.

  In the present embodiment, the switch 40 is described as being provided behind the mouse body 10 and on the bottom surface 13 of the mouse body 10, but may be the surface of the placement unit 11. For example, the switch 40 may be provided in a portion of the mounting portion 11 that is smoothly curved and projects outward. This is because when operating the wireless mouse 1, the user always places the palm on the placement unit 11, and thus the user inevitably presses the hand when using the wireless mouse 1.

  Further, in the present embodiment, the vibration dynamo 20 only needs to be provided with two or more spherical magnets 23. For example, the three spherical magnets 23 may be provided, and the two spherical magnets 23 may be provided with magnets of other shapes or yokes (for example, steel balls).

  Further, in the present embodiment, the solar panel 30 is attached to the front of the mouse main body 10, but may be attached to the surface of the mouse main body 10. Specifically, the solar panel 30 should just be attached in the position which is not covered with a hand, when operating the wireless mouse 1 which can be generated also at the time of operation.

  Although the embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.
