Description

  The present invention relates to a mouse as an input device for a computer.

  There are several types of mice as computer input devices. Among them, optical mice that can be intuitively operated by operators are widely used. The optical mouse irradiates light from its bottom surface, detects reflected light reflected by a desk or the like with a built-in optical sensor, and outputs the detected data to a computer. Further, it detects that the click button on the front or side of the mouse is pressed, and outputs the detected data to the computer. As a result, the pointer on the computer display is moved, and the menu and the like are determined.

  Computers have come to be used in a wide variety of places. Along with this, a mouse, which is an input device of a computer, is required to have performance according to the use environment. For example, there is a demand to use a mouse in an environment that handles water such as on board, in a kitchen, and in a bathroom. In the mouse, various electronic circuits such as a light emitting element such as an LED, an optical sensor such as an image sensor and an optical coupling, a signal processing IC, and a resistance element are arranged. Electronic components are vulnerable to moisture, and if water enters inside, there is a risk that the electronic circuit will be damaged and the mouse will not work.

  Furthermore, there are many demands to operate a personal computer using a mouse in a place where cleanliness is required, for example, in an operating room or a fish or meat cooking site. Particularly in recent years, in cardiac catheterization, CT data has come to be used during surgery like CADCAD data in the industry, and CT scanners have also been introduced in the field of dental treatment and displayed on a personal computer screen. The situation of advancing dental treatment while visually confirming the treatment site with a CT image has increased, and the situation of operating a personal computer via a mouse, such as switching of images according to the progress of surgery, movement of viewpoint and line of sight, enlargement processing, etc. doing. To use a mouse in a treatment room or operating room, it is essential to sterilize the mouse itself to prevent infection. For example, an autoclave sterilization process (high pressure steam sterilization process) of about 20 minutes at 2 to 2.2 atmospheres and 121 to 135 ° C. is effective. However, the risk of mouse damage makes mouse sterilization virtually impossible.

  In addition, as literature regarding a mouse | mouth, Unexamined-Japanese-Patent No. 9-319515 (patent document 1) is mentioned. This Patent Document 1 describes a computer input mouse in which an upper mouse case that is held by the hand of a person who operates a button is formed of a synthetic resin subjected to antibacterial treatment.

JP-A-9-319515

  The mouse described in Patent Document 1 has a structure in which an upper mouse case that is gripped by the hand of the person who operates the button is formed of a synthetic resin subjected to antibacterial treatment. No sealing means are taken. For this reason, if the mouse is used in an environment where water is used as described above, water will enter the mouse from between the upper mouse case and the button, the electronic circuit inside the mouse will be damaged, and the mouse will become inoperable. There is a fear. As a result, the usage environment of the mouse is limited. In addition, in the case of the mouse of Patent Document 1, the structure of the mouse cover is single, and the material is not sufficient in heat resistance and pressure resistance, and it is difficult to withstand changes in external pressure and temperature. In this respect as well, the usage environment is limited.

  An object of the present invention is to expand the use environment of a mouse.

  A mouse according to an embodiment of the present invention is equipped with a detection circuit that detects movement, at least one switch, a transmission circuit that wirelessly transmits data relating to movement detected by the detection circuit and data relating to operation of the switch to the outside. Circuit board. The circuit board is held on the bottom made of hard resin together with the power source. The bottom part is covered with a hard resin casing, and the casing and the bottom part form an outer shell, each having sufficient strength to withstand changes in external pressure and temperature. A circuit board and a power source are accommodated in the bottom and the casing.

  A cover can be provided outside the outer shell (or casing), and in that case, an adhesive, an adhesive sheet, a heat insulating sheet, or the like may be interposed between the outer shell (or casing) and the cover. However, these adhesives, adhesive sheets, heat insulating sheets, and the like can be made of special materials for bonding strength, heat insulating properties, pressure resistance, heat shielding properties, and the like.

  In one embodiment, at least one hard resin button for operating the switch is inserted in a sealed state at the upper part of the outer shell (or housing), or in order to minimize the loss of heat insulation effect. Further, a part of the outer shell (or casing) is subjected to pressure change in an uneven shape, whereby the internal switch can be turned on and off.

  In another embodiment, instead of inserting the button of the switch into the outer shell (or housing), the switch is configured as a surface-mounted waterproof switch installed on the surface of the outer shell (or housing). The waterproof switch does not slide with respect to the outer shell (or casing) and operates by being pushed in. The outer shell (bottom, casing) and the entire outer surface of the button are covered with a cover made of rubber, silicone rubber, resin or the like having elasticity, heat resistance and water resistance. As a result, the internal space defined by the outer shell (bottom, casing) and buttons is sealed.

  Materials such as ceramic vacuum beads, hollow silicone beads, hollow glass beads, hollow resin particles, and hollow nanosilica can be used as the fine particles (heat insulating particles) mixed in the resin for improving heat insulation and the like.

  The outer shell (bottom or casing) can be provided with a pressure regulating valve mechanism for regulating the pressure inside the mouse.

  Hereinafter, the mouse according to the present embodiment will be described with reference to the drawings. In the following description, components having substantially the same function and configuration are denoted by the same reference numerals, and redundant description will be given only when necessary.

(First embodiment)
FIG. 1 is a perspective view showing an appearance of a mouse 10 according to the first embodiment. FIG. 2 is a cross-sectional view of the mouse 10 shown in FIG. FIG. 3 is a block diagram showing a configuration of the mouse 10 of FIG. The mouse 10 functions as a man-machine interface for an operator to input instructions such as movement of a cursor on the display screen and determination of a menu to the computer.

  The mouse 10 has an outer shell (shell) 12. The outer shell 12 includes a plurality of members, here, a bottom portion 14, a housing 13, and click buttons 15 and 16. However, the outer shell 12 may be composed only of the housing 13 and the bottom portion 14, and may have a configuration other than the configuration composed of the housing 13 and the bottom portion 14, for example, a structure in which the whole is configured as an integral object, or A portion different from the casing 13 and the bottom portion 14 in this embodiment, for example, a position higher than the middle of the height dimension of the outer shell 12, or a division into two or more in the major axis direction or minor axis direction of the mouse 10 A division structure that is divided by a number, or a division structure that is two or more divisions at various other division positions may be used.

  The bottom 14 is a substantially oval plate made of hard resin. A power supply unit 40 is held together with the circuit board 19 on the upper surface of the bottom portion 14. As will be described in detail later, the circuit board 19 is equipped with a detection circuit for detecting movement, at least one switch, a transmission circuit for wirelessly transmitting data relating to movement detected by the detection circuit and data relating to operation of the switch to the outside. Is done.

  The housing 13 is a substantially semi-elliptical sphere made of a hard resin having a hollow inside. The housing 13 is placed on the bottom portion 14 in a state where the circuit board 19 and the power supply unit 40 are accommodated. Two click buttons 15 and 16 for operating left and right switches 31 and 33 (described later) are inserted in a sealed state at the top of the housing 13 in at least one position, here two positions, In order to minimize the loss, a part of the casing is subjected to pressure change in an uneven shape. In this way, the internal switches 31 and 33 can be turned on / off by partially changing the pressure of the housing 13 in an uneven shape. Click rods 17 and 18 of prismatic bodies are connected to the inside of the click buttons 15 and 16. The click rods 17 and 18 pass through the housing 13 in a sealed state at two positions and extend toward the bottom portion 14. The tips of the click rods 17 and 18 are aligned with the left and right switches 31 and 33 mounted on the circuit board 19. For example, when the click button 15 is pressed, the switch 31 is pressed via the click rod 17. As will be described later, the entire outer surface of the bottom part 14, the housing 13 and the click buttons 15 and 16 are covered with a cover 11 made of rubber, silicone rubber, resin, etc. having elasticity, heat resistance and water resistance, The mouse as a whole has waterproofness, heat resistance, and impact resistance.

  The casing 13 and the bottom 14 constituting the outer shell 12 are mixed with a rod-shaped material made of glass fiber having heat resistance and strength higher than the resin used for the casing 13 or a solid material that easily forms an undercut. Then mold. Moreover, the glass fiber used for this may be subjected to a silane coupling treatment for obtaining adhesion with the main material of the housing 13. Next, all or part of the outer surface of the housing 13 is melted with a laser, electromagnetic waves, light, flame, radiant heat, electric heat, or the like, and the surface layer is removed. Thereby, the glass fiber etc. which were included are exposed to the surface. After that, the randomly exposed glass fiber has a sufficient fitting force to double-mold the cover 11 and join it to the housing 13.

  A plurality of electronic components corresponding to the switches 31 and 33, the position detection unit 35, the wireless communication unit 37, and the control unit 39 are mounted on the circuit board 19. The power supply unit 40 includes a primary battery such as a dry battery or a button battery. The power supply unit 40 supplies power to the control unit 39 and the like. The switches 31 and 33 generate ON / OFF signals by physical contact.

  The position detection unit 35 typically includes a light emitting element made of a laser, a blue LED, or the like and an image sensor. The light emitting element generates light. The light generated from the light emitting element passes through the optical component composed of the front lens and the prism and is emitted from the light transmitting portion of the bottom portion 14. A part of the light emitted from the translucent part of the bottom part 14 and irregularly reflected by the mouse pad, for example, forms an image on the image sensor by the rear lens of the optical component. The position detection unit 35 calculates the movement direction and the movement amount from the changes in the images before and after read by the image sensor. Data relating to the movement direction and movement amount of the mouse 10 calculated by the position detection unit 35 is output to the control unit 39. Note that at least a biaxial acceleration sensor may be provided in place of the light emitting element and the image sensor. Based on the output of the biaxial acceleration sensor, the movement direction and the movement amount of the mouse 10 are calculated by the position detection unit 35.

  Under the control of the control unit 39, the wireless communication unit 37 repeatedly transmits data relating to movement of the mouse 10 and ON / OFF signals of the switches 31 and 33 to the wireless reception unit of the computer. As a wireless system, either an infrared system or a radio system such as Bluetooth (registered trademark) may be used. In addition, the wireless system may be wireless communication using a sound in an audible range that can be heard by a human or a sound in a high audible range that is difficult for a human to hear.

  The outer shell 12 of the mouse 10 including the bottom portion 14, the housing 13, and the click buttons 15 and 16 is uniformly covered by the cover 11. Actually, the cover 11 is in close contact with the outer surface of the bottom portion 14, the housing 13 and the click buttons 15 and 16. Adhesiveness and bondability can be improved by joining the cover 11 to the assembled bottom portion 14, housing 13, and click buttons 15, 16 by insert molding. The cover 11 can be made of a material such as rubber, silicone rubber, or resin having elasticity, heat resistance and water resistance, but the cover 11 of this embodiment is made of an elastic resin to ensure button operability. is there. Examples of the elastic resin include natural rubber, silicone rubber, nitrile rubber, urethane rubber, fluorine rubber, etc. In addition to elasticity, the rubber is made of silicone rubber or fluorine from the viewpoint of heat resistance, water resistance, durability, transparency, and the like. It is preferably made of rubber. Furthermore, the surface of the cover 11 may be lubricated to improve mobility.

  The entire outer surface of the bottom 14, the housing 13, and the click buttons 15, 16 are covered with the cover 11 as a unit without any gap. As a result, the internal space of the mouse 10 defined by the bottom 14, the housing 13, and the click buttons 15 and 16 is completely sealed. The inside of the mouse 10 is completely shielded from the outside by the cover 11 with respect to liquid, more preferably gas.

  The casing 13, the bottom part 14, and the click buttons 15, 16 constituting the outer shell 12 are made of the same hard resin, and the hard resin has resistance and strength against changes in pressure and temperature. Examples of the hard resin include general-purpose resins such as polyethylene (PE), polypropylene (PP), polystyrene (PS), acrylonitrile / styrene resin (AS), acrylonitrile / butadiene / styrene resin (ABS), and polyvinyl chloride (PVC). General-purpose engineering resins such as polyamide (PA), polyacetal (POM), polycarbonate (PC), modified polyphenylene ether (PPE), polyethylene terephthalate (PET), liquid crystal polymer (LCP), polyphenylene sulfide (PPS), polyimide (PI), Super engineering resins such as polyethersulfone (PES), polyetheretherketone (PEEK), polytetrafluoroethylene (PTFE), polyamideimide (PAI) But pressure resistance, super engineering resin in view of heat resistance, typically PPS, PES, PEEK, and most preferably PPS.

  The high hardness of the outer shell 12 contributes to the protection of the circuit board 19 accommodated in the outer shell 12 while maintaining the shape of the mouse 10. Further, the high elasticity of the cover 11 makes it easy for the operator to press the click buttons 15 and 16 from above the cover 11. Moreover, the high transparency of the cover 11 realizes an improvement in the visibility of the click buttons 15 and 16 before and after the mouse 10 by the operator. In other words, the operability of the mouse 10 by the operator is improved by the resin cover 11 having high elasticity and high transparency and the resin outer shell 12 having high rigidity. Further, the heat resistance and water resistance of the cover 11 are high, and the heat resistance of the outer shell 12 is high, so that the sterilization process by heat of the mouse 10 can be realized. Examples of heat sterilization include autoclave sterilization and dry heat sterilization. In the autoclave sterilization treatment, for example, heat treatment is performed at about 2 to 2.2 atm and 121 to 135 ° C. for about 20 minutes. In the dry heat sterilization treatment, for example, heat treatment is performed at 180 to 200 ° C. for 30 minutes in dry air.

  For example, silicone rubber does not change its properties in an environment of over 150 ° C., and can withstand continuous use for 10,000 hours or more in an environment of over 200 ° C. Silicone rubber has a low water absorption of 1% regardless of the temperature of cold water, hot water, boiling water, etc., even if it is immersed for a long time, and does not affect the physical characteristics. In addition, PES, one of the super engineering resins, has a deflection temperature under load of 200-210 ° C, and its use temperature is a product safety standard established by UL (Underwriters Laboratories Inc.). It is certified at 180-190 ° C.

  For example, if a silicone resin is used, the silicone resin is composed of a siloxane bond having a silicon-oxygen bond as a skeleton, and has superior heat resistance compared to organic materials such as organic rubber having a carbon-carbon bond as a skeleton. Have

  That is, even if the mouse 10 is exposed to high-temperature and high-pressure steam in the course of autoclave sterilization treatment by the resin cover 11 having high water resistance and high heat resistance and the resin outer shell 12 having high heat resistance, Its strength can be maintained. For this reason, the mouse 10 can be used as an input device for a computer in an operating room, for example, which requires sterilization each time it is used.

  In addition, this embodiment does not deny applying general-purpose resin and engineering resin as hard resin, and applying other resin as elastic resin, and comprises the cover 11 according to the use environment of the mouse 10. The elastic resin and the hard resin constituting the outer shell 12 may be selected from a plurality of types of resins. For example, in the case of a kitchen and a bathroom where water may adhere but not in a high temperature environment, the cover 11 has a water resistance equivalent to that of silicone rubber, and is less heat resistant than silicone rubber. It may be made of nitrile rubber. The outer shell 12 may be made of engineering resin or general-purpose resin such as polyvinyl chloride (PVC). Furthermore, although there is no possibility of water being attached, the cover 11 may be made of urethane rubber having low water resistance and low heat resistance in a factory or the like where dust resistance is required.

(Second Embodiment)
The mouse 10 according to the second embodiment includes a structure for fixing the cover 11 to the outer shell 12. FIG. 4 is a view showing a cross section of the mouse 10 according to the second embodiment. FIG. 5 is a view showing another cross section of the mouse 10 according to the second embodiment.

  As shown in FIG. 4, the cover 11 is bonded to the outer shell 12 with an adhesive 21. Thereby, the cover 11 is firmly joined to the outer shell 12. By firmly joining the cover 11 to the outer shell 12, the lateral displacement of the cover 11 with respect to the outer shell 12 when the mouse 10 is moved is suppressed, which contributes to improving the operability of the mouse 10. An epoxy-based elastic adhesive is employed as the adhesive 21 in order to ensure substantial adhesive strength. This epoxy-based elastic adhesive has high heat resistance and can suppress deterioration of adhesive strength due to heat treatment of the mouse 10.

  In addition, among the methods for bonding the outer shell 12 (that is, the housing 13 and the bottom portion 14) and the cover 11, some methods other than the above will be described.

  First, the method of using an epoxy adhesive as the adhesive 21 is as described above.

  In another method, when a sheet having the same component as the outer shell 12 is used for the adhesive 21, the adhesive 21 and the outer shell 12 are easily fused. Joining is completed by pre-working a mechanical undercut in which the material of the cover 11 is fitted to the outer surface of the sheet (contact surface with the cover 11) during double molding.

  In still another method, fine fibers such as cellulose, nanocellulose fibers, and carbon fibers are interposed in the portion of the adhesive 21 between the outer shell 12 and the cover 11, so that the outer shell 12 and the fibers are separated. The cover 11 and the fiber are strongly fitted, and the outer shell 12 and the cover 11 have a strong adhesive force and are firmly bonded to each other.

  In another method, fine fibers suitable for the outer shell 12 and the cover 11 are previously planted on both surfaces of the sheet interposed in the portion of the adhesive 21 between the outer shell 12 and the cover 11. Double molding with stronger adhesive strength is possible.

  The internal temperature of the cover 11 varies according to changes in the temperature environment to be used. When the internal temperature of the cover 11 rises, the volume of the gas filled in the cover 11 increases accordingly. As the gas volume increases, the internal pressure increases. Then, the cover 11 may be peeled from the outer shell 12. This possibility of peeling can be suppressed by firmly bonding the cover 11 to the outer shell 12 with the adhesive 21.

  Furthermore, in order to suppress the possibility of peeling, the mouse 10 can be manufactured so that its internal pressure is lower than atmospheric pressure at a reference temperature (for example, 25 ° C.). Even if the internal pressure increases as the internal temperature of the cover 11 increases, if the increased internal pressure is lower than the atmospheric pressure (1 atm), the cover 11 is pressed against the outer shell 12 by the atmospheric pressure. The possibility of peeling from the shell 12 is suppressed. The mouse 10 may have a vacuum inside the cover 11. However, the internal pressure of the mouse 10 needs to be a pressure that does not adversely affect the pressing operation of the click buttons 15 and 16 and the switches 31 and 33 and the return operation.

  Further, an insulating resin may be filled in the internal space defined by the casing 13, the bottom portion 14, and the click buttons 15 and 16 constituting the outer shell 12. Since the thermal expansion coefficient of the resin is much lower than that of gas, it is possible to effectively suppress the possibility of the cover 11 being peeled due to an increase in internal pressure.

  In order to improve the bonding strength between the cover 11 and the outer shell 12 (comprising the housing 13 and the bottom portion 14), an adhesive sheet 22 is interposed between the outer shell 12 and the cover 11 as shown in FIG. Also good. The adhesive sheet 22 is formed by mixing inorganic fibers or organic fibers into a resin that is highly compatible with the resin constituting the outer shell 12 including the housing 13 and the bottom portion 14. Examples of the inorganic fiber include glass fiber, steel fiber, and carbon fiber. Examples of organic fibers include olefin fibers, polyvinyl alcohol fibers, pulp fibers, cellulose, nanocellulose fibers, and other natural fibers such as hemp. Further, the adhesive sheet 22 may be made of a resin having high compatibility with both the resin constituting the cover 11 and the resin constituting the outer shell 12. The adhesive sheet 22 is a sheet in which glass fibers are mixed in the same resin as the outer shell 12, for example, a PPS sheet in which glass fibers are mixed. After the outer shell 12 is molded, high-temperature silicone rubber is poured in a state where the adhesive sheet 22 is disposed on the surface of the outer shell 12. The adhesive sheet 22 and the surface of the outer shell 12 are melted by the heat of the silicone rubber. Since the resin of the adhesive sheet 22 and the resin of the surface of the outer shell 12 are mutually compatible, the adhesive sheet 22 is firmly bonded to the surface of the outer shell 12. Moreover, silicone rubber is entangled with the glass fiber contained in the adhesive sheet 22 by flowing the silicone rubber in a state where the adhesive sheet 22 is melted. Thereby, the adhesive sheet 22 and the cover 11 are firmly joined to each other. That is, the outer shell 12 and the cover 11 are firmly joined to each other by insert-molding the cover 11 with respect to the outer shell 12 with the adhesive sheet 22 interposed between the outer shell 12 and the cover 11. . In addition, although adhesive strength increases by compatibility, the method using a primer may be used incidentally or independently besides the joining by compatibility.

  Further, as the adhesive sheet 22, PPS (polyphenylene sulfide) may be used, and furthermore, thin and flexible fibers such as Japanese paper, fibers such as cellulose or nanocellulose, carbon fibers, and glass fibers are used as bonding inclusions. May be used. Further, a PPS sheet formed by weaving a thin hollow tube of PPS resin into a sheet shape, or a PPS resin bonding material in which numerous irregularities and undercuts are provided on a sheet by special laser processing may be used. Further, heat insulating grains and hollow ceramic beads may be mixed in the adhesive sheet 22 to enhance the bonding strength and heat insulating performance. Moreover, in order to give the heat insulation of the adhesive sheet 22, it is also effective to use a sheet knitted with a PPS tube or an adhesive containing ceramic hollow beads as the adhesive sheet 22.

(Third embodiment)
Further, for example, it is necessary to protect the electronic device, the electronic circuit, the electronic element, the power supply unit 40, and the like on the circuit board 19 which is an electronic part from a high temperature during autoclave sterilization. Therefore, it is also effective to surround the circuit board 19 and the power supply unit 40 with a heat insulating material. The mouse 10 according to the third embodiment includes a structure for improving heat insulation. FIG. 6 is a view showing a cross section of the mouse 10 according to the third embodiment. FIG. 7 is a view showing another cross section of the mouse 10 according to the third embodiment.

  As shown in FIG. 6, the heat insulating sheet 23 is disposed so as to cover the entire circuit board 19 in the outer shell 12. The heat insulating sheet 23 is configured by mixing heat insulating grains into main fibers. Examples of the main fiber include glass fiber and pulp fiber. Examples of the heat insulating particles include ceramic vacuum beads, hollow glass beads, hollow resin particles, and hollow nanosilica having a very high heat insulating performance due to a very high heat reflectivity and a very low heat conductivity. Therefore, the heat insulation sheet 23 is disposed so as to cover the circuit board 19 and the power supply unit 40 in the outer shell 12, and an increase in the internal temperature of the circuit board 19 and the power supply unit 40 is suppressed.

  Further, as the heat insulating sheet 23, a paper heat insulating material (heat insulating paper) having heat insulating performance is used, and ceramic vacuum beads, hollow silicone beads, hollow glass beads, hollow resin particles, hollow nano silica are included in the heat insulating paper. Insulating grains such as may be mixed. Furthermore, as shown in FIGS. 6 and 7, in particular, surrounding the electronic devices such as the circuit board 19, the position detection unit 35, the wireless communication unit 37, the control unit 39, and the power supply unit 40 with the heat insulating sheet 23 The effect can be enhanced. At that time, if the heat insulating sheet 23 is enclosed in double or triple, the heat insulating effect can be further enhanced.

  In addition, the position which arrange | positions the heat insulation sheet 23 is not limited above. As shown in FIG. 7, a heat insulating sheet 23 may be disposed between the outer shell 12 and the cover 11 in order to suppress an increase in the internal temperature due to the external temperature. As a result, the rise in internal temperature is suppressed in the same manner as described above, and the electronic device, electronic circuit, electronic element, power supply unit 40, etc. on the circuit board 19 that is an electronic part are protected from high temperatures during autoclave sterilization, for example. can do. Furthermore, the heat insulation sheet 23 can also obtain the effect of improving the adhesiveness between the outer shell 12 and the cover 11 in addition to the heat insulation effect.

  In addition, in order to suppress an increase in internal temperature due to external temperature, heat insulating particles such as ceramic vacuum beads, hollow glass beads, hollow resin particles, and hollow nanosilica are provided on at least one or both of the outer shell 12 and the cover 11. You may comprise so that the heat insulation of the outer shell 12 and the cover 11 may be improved by mixing.

FIG. 9 is a cross-sectional view of the mouse 10 shown in FIG. The mouse 10 may have a power generation function. Specifically, the power supply unit 40 includes a secondary battery, a solar panel 25, and a charging circuit. The secondary battery is a lithium ion battery or the like. The solar panel 25 may be flexible and is disposed over the entire upper surface of the outer shell 12 between the outer shell 12 and the cover 11. The solar panel 25 generates electric power from light energy such as sunlight and a fluorescent lamp. The electric power generated by the solar panel 25 is charged to the secondary battery via the charging circuit. The electric power charged in the secondary battery is supplied to each unit such as the control unit 39. The provision of the power generation function of the mouse 10 gives the mouse 10 a wireless function and contributes to the expansion of the usage environment of the mouse 10. The solar panel 25 may be disposed on a part of the upper surface of the outer shell 12. For example, you may arrange | position the solar panel 25 in the rear part except the surface of the click buttons 15 and 16 on the upper surface of the outer shell 12. FIG. By disposing the solar panel 25 on the portions other than the surfaces of the click buttons 15 and 16, the surface of the solar panel 25 and the strength deterioration of the solar panel 25 due to repeated pressing of the click buttons 15 and 16 are suppressed. can do.

  The mouse 10 may have a non-contact charging function. Specifically, the power supply unit 40 includes a secondary battery and a non-contact charging unit. The non-contact charging method includes an electromagnetic induction method using electromagnetic induction, an electromagnetic resonance method using an electromagnetic field resonance phenomenon, and a radio wave method for obtaining electric power by converting an electromagnetic wave received by an antenna provided in the mouse 10. Either method may be used. Alternatively, an ultrasonic method may be used in which electric power is obtained by converting ultrasonic waves received by a piezoelectric element provided in the mouse 10.
