Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In principle, the same reference numerals are given to the same parts throughout the drawings, and redundant description is omitted.

< embodiment 1>

A mouse according to embodiment 1, which is an example of an electronic device according to the present invention, will be described with reference to fig. 1 to 6. The mouse according to embodiment 1 is a medical mouse that improves the sanitary environment in a medical field such as a hospital and can be sterilized by an autoclave, in other words, a sterilizable mouse. For example, in examination, surgery, or the like, there is a case where a system including a computer and a medical apparatus to which a mouse is connected is desired to be used. In this case, by using the sterilized mouse, it is possible to reliably prevent infection and realize advanced medical treatment using a system function such as navigation technology. For example, a person performing an operation can operate a mouse to reliably obtain a three-dimensional image, thereby improving the quality of the operation or the like. The mouse not only has an optical mouse function, but also can be applied to sterilization treatment such as autoclave treatment together with medical equipment in a use environment such as a medical field, thereby achieving effects such as prevention of infection and improvement of medical efficiency.

First, embodiment 1 shows a basic configuration including a transmission unit, and embodiment 2 and the like described later further show a configuration in which a heat insulating structure and the like are added. As shown in fig. 2 and the like, the mouse according to embodiment 1 has a structure in which components of the mouse function are spatially separated and arranged by using the transmission unit 6. In this structure, the lens 4 serving as an optical element in the opening R1 of the case bottom 2B and the electronic circuit component 5 of the substrate 10 are connected by being separated vertically by the transmission unit 6 such as the optical fiber 6 f.

[1-1: mouse as a whole

Fig. 1 is a perspective view showing the entire appearance of a mouse 1 as a mouse according to embodiment 1. The mouse 1 is a medical mouse used as an input device of a computer. The housing 2 of the mouse 1 has a housing upper part 2A and a housing bottom part 2B. The housing upper portion 2A is a portion to be held by a hand of a user, and has a roughly elliptic curved surface shape or a free curved surface shape. Buttons (also referred to as on-off buttons, click buttons, and the like) 3 for input operation, for example, two left and right buttons 3, are provided at positions in front of the upper case portion 2A. The button 3 is a button that can be pressed by a finger in response to an operation such as clicking by the user. Further, although the case of the two-button system is shown, the present invention is not limited to this, and a system having any number of buttons, such as one button, three buttons, and the like, may be included. The case bottom 2B is a substantially flat plate-shaped portion provided on the mouse installation surface. In the case bottom 2B, an opening R1 in which an optical element or the like is provided at a position offset in one longitudinal direction from the center position of the housing 2. The case upper part 2A and the case bottom part 2B are joined after the components are housed inside at the time of mouse manufacture. The mouse 1 according to embodiment 1 is a wireless communication type or wireless charging type mouse, and is configured without a cable or the like extending to the outside of the housing 2.

The mouse 1 of embodiment 1 shown in fig. 2 to 5 has the following structure: (a) an optical fiber 6f serving as the transmission section 6; (b) wiring the transfer part 6 in the housing 2 via the front side; and (c) a light source unit 7 and a power supply unit 8 are provided. In this configuration, for example, (d) when one electronic circuit component 5 is provided on the substrate 10, and (e) the positional relationship between the lens 4 of the opening R1 and the electronic circuit component 5 of the substrate 10 in a plan view of a horizontal plane is as follows: the electronic circuit component 5 is disposed at a position separated as much as possible from the opening R1 in the longitudinal direction of the housing 2 among the positions on the substrate 10 (the right side position in the opposite direction to the position of the left opening R1 in fig. 3), and heat conduction due to the intrusion of heat from the outside of the mouse through the opening R1 is prevented. (f) In addition, by disposing not only the electronic circuit component 5 but also the light source unit 7 and the power supply unit 8 above the substrate 10, it is possible to prevent heat from entering the substrate 10 from the outside of the mouse through the opening R1 from below as much as possible. (g) Further, as shown in fig. 3, the planar shape of the substrate 10 is formed in a substantially elliptical shape similar to the substantially elliptical shape of the inner surface of the structure surface of the housing 2, and as described later, the distance from the structure surface of the housing 1 is made as uniform and large as possible over the entire circumference of the substrate 10, so that the amount of heat entering from the outside through the structure surface of the housing 2 can be prevented as much as possible. The substrate 10 is preferably supported by a support mechanism made of a heat insulating material or the like, for example, but is omitted in fig. 2 for clarity of description.

[1-2: mouse longitudinal section

Fig. 2 shows an outline of a vertical cross section (Y-Z plane corresponding to line a-a in fig. 1) of the mouse 1 according to embodiment 1. Fig. 2 shows a state where the housing bottom portion 2B is placed on the installation surface SF such as a mouse pad. A part of the case bottom 2B has a pad 2B 1. The pad portion 2B1 is formed by, for example, grinding and coating. Thereby, a space for light to enter is formed between the installation surface SF and the main surface of the case bottom portion 2B.

The push button 3 of the housing 2 shows a structure of the type in fig. 2 without a lever or the like. The push button 3 is electrically connected to the electronic circuit component 5 of the substrate 10 through a wiring 3c (e.g., a heat-resistant wire). The push button 3 may be made of a member having heat resistance, water resistance, pressure resistance, or the like, for example, or may be covered with a cover having heat resistance, water resistance, pressure resistance, or the like, when the push button does not have heat resistance, water resistance, pressure resistance, or the like. The push button 3 is made of, for example, a flexible (elastic) resin, and is deformed into a concave-convex shape in response to a pressing operation by a user. In response to the deformation of the push button 3, a not-shown switch circuit on the lower side of the push button 3 is electrically turned on/off, and an on/off signal is output from the wiring 3 c. The push button 3 may be formed as a part of the housing 2.

The mouse 1 includes elements such as a lens 4, a substrate 10, a light source unit 7, a power supply unit 8, and a transmission unit 6 in a housing 2. The optical mouse of the mouse 1 is mainly configured by connecting the lens 4, the transmission unit 6, the image sensor 15 (described in detail in fig. 5) and the electronic circuit component 5. The internal space of the housing 2 is roughly divided into a first space portion SP1 below the substrate 10 and a second space portion SP2 above the substrate 10. The lens 4 is disposed in the opening R1 of the case bottom 2B. The lens 4 is an optical element (in other words, an image light incident portion) that is disposed in a part of the housing bottom portion 2B (the opening portion R1) and receives light (image light) from the outside as an optical signal. The lens 4 is not limited to one lens, and may be configured by a plurality of lenses, or may have a member such as a mirror. The lens 4 is fixed in close contact with the housing bottom 2B. The lens 4 collects light from the installation surface SF outside the housing 2 into image light (optical signal) and inputs the image light, and the image light enters one end of the transmission unit 6.

Electronic components such as the electronic circuit component 5 are mounted on the substrate 10, and an image sensor 15 as shown in fig. 5 described later is connected to the electronic circuit component 5. The electronic circuit component 5 and the image sensor 15 are objects to be protected by heat or water (water vapor) during the sterilization process. The electronic circuit part 5 shows a case where a controller of a mouse function, a wireless communication function, a wireless charging control function, and the like are integrally realized. The controller of the electronic circuit part 5 controls image processing of an image by the image sensor 15, input processing of the button 3, and the like, and also controls wireless communication, wireless charging, and the like. The controller of the electronic circuit part 5 calculates the state of movement of the mouse 1 from the difference of the images at each time point based on the image detected by the image sensor 15. In addition, the controller detects the on/off state of the button 3. The controller transmits information indicating the state of the mouse 1 to an external computer or the like via the wireless communication circuit. Further, only one electronic circuit component 5 is shown, but the present invention is not limited thereto, and a plurality of electronic circuit components and other components may be provided on the substrate 10 as described later.

The transmission unit 6 is constituted by an optical fiber 6f (in other words, an image fiber, an optical cable, or the like). In the mouse 1, an optical fiber 6f of an image light direct transmission system is applied to the transmission unit 6. The optical fiber 6f is a portion that directly transmits image light as an optical signal incident through the lens 4 to the image sensor 15. The optical fiber 6f optically connects the lens 4 and the image sensor 15. The optical fiber 6f has one end connected to, for example, the lens 4 and the other end connected to the image sensor 15. These connections are optical connections that, together with physical connections, ensure direct transfer of image light. The structure of the connection is not limited. The optical fiber 6f may have a bend in a transmission path because of its flexibility.

In the wiring example (wiring example 1) of fig. 2 to 4, the optical fiber 6f is connected to the image sensor 15 on the upper surface side of the electronic circuit component 5 on the upper surface side of the substrate 10 via, for example, wiring in the vicinity of the front surface in the case 2.

The light source section 7 is a portion (light emitting element) that generates and supplies illumination light, and is formed of, for example, an LED element, but is not limited thereto, and may be formed of a laser light source or the like. The light source section 7 supplies the generated illumination light to the lens 4 of the opening R1. In this example, the light source unit 7 is disposed above the substrate 10. The light source unit 7 is connected to the electronic circuit component 5 of the substrate 10 via a wiring 7 c. The electronic circuit component 5 controls the light emission of the light source section 7 by a light source control signal. The position of the light source unit 7 may be arbitrary and is not limited. Illumination light from the light source section 7 is supplied to the lens 4 through, for example, a light source section wiring 7 d. Further, the illumination light may be provided using an optical member such as a light guide. The light source section wiring 7d may use an optical fiber, for example, in the same manner as the transmission section 6. When a plurality of optical fibers are used for the transmission unit 6 and the light source unit 7, these optical fibers may be bundled. Further, even when the light source unit 7 is not provided as shown in fig. 6 described later, the mouse function can be realized when the illumination light of the use environment is sufficient.

The power supply unit 8 is connected to the substrate 10 through a wiring 8 c. The power supply unit 8 is disposed on the substrate 10, for example, at a position near the center. The power supply unit 8 supplies power to the electronic circuit component 5 and the like. The arrangement position of the power supply unit 8 may be arbitrary and is not limited. The power supply unit 8 is a wireless charging unit in embodiment 1, and has a circuit and a secondary battery for receiving wireless charging between the wireless charging unit and the installation surface SF (for example, a mouse pad) in a wireless charging manner. The wireless charging method is not limited to the wireless charging method, and a known method such as a magnetic field coupling method, an electric field coupling method, a laser method, a microwave method, and an ultrasonic method may be applied.

The power supply unit 8 is not limited to the wireless charging unit, and may be a primary battery. In this case, the case 2 may be a primary battery that is replaceable with a cover. The portion including the cover has water resistance, heat resistance, and the like. The power supply unit 8 may be a secondary battery of a type in which a terminal is exposed on the outer surface of the case 2. In this case, the exposed terminals are smooth with respect to, for example, the main surface of the case bottom 2B. By smoothing the surface, the surface has a property of being hard to attach stains (stain-proofing property) and a property of being easy to remove stains (easy-to-clean property).

The power supply unit 8 is disposed above the substrate 10 as a whole in this example. However, as shown in the embodiment and the modification described later, the present invention is not limited to this, and at least a part of the present invention may be disposed on the substrate 10. Further, a substrate for mounting the light source unit 7, a substrate for mounting the power supply unit 8, a substrate for mounting the communication unit or the communication mechanism, and the like may be provided separately from the substrate 10. These plural substrates are accommodated in the housing 2. In the housing 2, the plurality of substrates may be arranged in a horizontal direction or may be stacked in a vertical direction. The plurality of substrates may be formed into a three-dimensional stepped or layered structure. The respective substrates may be disposed vertically in the housing 2 or may be disposed obliquely to the horizontal. When the substrate is divided into a plurality of substrates, the arrangement positions can be easily and specifically divided according to the temperature and the degree of heat insulation of each member.

The mouse 1 can separate the lens 4 and the like of the opening R1 of the case bottom 2B from the image sensor 15 and the electronic circuit component 5 and the like in the case 2 as far as possible by using the optical fiber 6f as the transmission unit 6. In embodiment 1, the electronic circuit component 5 and the like are disposed at a position near the right end in the longitudinal direction in the case 2 (the position on the rear side of the mouse 1) in this example, as a preferable position separated as far as possible from the opening R1 provided near the one end in the longitudinal direction of the case bottom 2B (the position near the left end and on the front side of the mouse 1 in fig. 2 and 3). Therefore, the length of the optical fiber 6f is also increased, and therefore, the amount of heat transmitted from the lens 4 of the opening R1 to the electronic circuit component 5 and the image sensor 15 can be reduced as much as possible.

Thus, in the mouse 1 according to embodiment 1, as the positional relationship between the lens 4 of the opening R1 and the electronic circuit component 5 and the image sensor 15 on the substrate 10 in a plan view of the horizontal plane, the electronic circuit component 5 is disposed at a position as far as possible apart from the opening R1 in the position on the substrate 10 in the longitudinal direction of the housing 2 (as the position on the right side of fig. 3 which is the rear side of the mouse 1 in the direction opposite to the position of the opening R1 on the left side of fig. 3 which is the front side of the mouse 1), and is in a positional relationship in which heat conduction due to the intrusion of heat from the outside of the mouse through the opening R1 can be prevented as much as possible, and therefore, even when the mouse 1 is subjected to, for example, a sterilization treatment by high-temperature and high-pressure water vapor in an autoclave apparatus, it is possible to prevent as much as possible that the heat intruded from the outside of the mouse through the opening R1 and the lens 4 is conducted to the electronic And damage or malfunction of the image sensor 15.

Further, as shown in fig. 3, the planar shape of the substrate 10 is formed in a substantially elliptical shape similar to the substantially elliptical shape of the housing 2, so that the distance from the inner surface of the structural surface of the housing 2 is largely divided as uniformly as possible over the entire circumference of the substrate 10, and heat or the like entering from the outside through the structural surface of the housing 2 can be prevented as much as possible, and in this respect, the substrate 10 is configured to have a substantially elliptical shape so that the area of the substrate 10 is reduced as much as possible and the heat accumulated in the substrate 10 cannot be conducted to the electronic circuit components 5 or the like by heat conduction. As a result, even if the planar shape of the substrate 10 is a delicate surface, heat accumulation in the substrate 10 and heat conduction to the electronic circuit component 5 and the image sensor 15 can be prevented, and damage and failure of the electronic circuit component 5 and the image sensor 15 due to thermal attack can be prevented as much as possible.

In embodiment 1, as described above, fig. 2, 3, and the like, all of the electronic circuit component 5, the light source unit 7, and the power supply unit 8 are disposed above the substrate 10. As a result, even when the mouse 1 is subjected to sterilization treatment by high-temperature and high-pressure water vapor in the autoclave device, the electronic circuit component 5, the light source unit 7, and the power supply unit 8 are all separated from the housing bottom portion 2B by a distance K1 or more described below, so that the influence of the high-temperature and high-pressure water vapor and moisture can be prevented from being transmitted to all of the electronic circuit component 5, the light source unit 7, and the power supply unit 8, and all of the electronic circuit component 5, the light source unit 7, and the power supply unit 8 can be protected from damage or failure due to the high-temperature and high-pressure water vapor.

In embodiment 1, since the arrangement of the electronic circuit components 5 and the like in the housing 2 of the mouse 1 is very important in order to avoid damage or failure due to high temperature, high pressure, and water vapor, the arrangement and distances in the X, Y, and Z directions of the electronic circuit components 5, the substrate 10, the image sensor 15, and the like in the housing 2 of the mouse 1 will be described in detail below.

As shown in fig. 2, the distance K1 is a distance between the lower surface of the case bottom portion 2B and the lower surface of the electronic circuit component 5 in the up-down direction of fig. 2, i.e., the Z direction. The distance K2 is the distance between the upper surface of the case bottom portion 2B and the lower surface of the substrate 10 in the Z direction, and is the distance in the first space portion SP 1. By securing the distance K1 and the distance K2, an effect is obtained that heat conduction from the outside of the case bottom portion 2B to the upper side can be prevented. Since the mouse 1 is provided with the first space portion SP1 using the transmission unit 6, the heat insulation performance and the like can be improved by the amount of the space. In designing the distance K2 or the like of the space, an appropriate distance can be selected in consideration of the heat insulation property or the like.

Further, a distance K3 is a distance between the upper surface of the electronic circuit component 5 and the outer surface of the case upper part 2A in the Z direction in the upper middle second space part SP2 of the electronic circuit component 5. Since the distance K3 is sufficiently secured, the electronic circuit component 5 can be protected from heat or the like transferred downward from the outside of the case upper portion 2A.

The distance K4A (fig. 2 and 3) is a distance between the center of the electronic circuit component 5 and the lower side surface of one end portion in the longitudinal direction (the right end portion in fig. 2 and 3) of the housing upper portion 2A in the longitudinal direction of the housing 2 of the mouse 1 in fig. 2 and 3, that is, the Y direction which is the front-rear direction. In embodiment 1, the distance K4A is shortened as much as possible, and the distance K6, which is the distance between the lower side surface of the one end portion in the longitudinal direction of the housing upper portion 2A (the left end portion in fig. 2 and 3) and the opening R1 and the lens 4, is also shortened as much as possible. As a result, in embodiment 1, the distance K7, which is the horizontal distance between the opening R1 and the lens 4 and the electronic circuit component 5, is made as long as possible, that is, the opening R1 and the lens 4 are spaced apart from the electronic circuit component 5 as far as possible in both the horizontal direction and the vertical direction, and the electronic circuit component 5 is made as short as possible by high heat or the like entering the mouse 1 from the portion of the opening R1 and the lens 4.

On the other hand, the distance K4B (fig. 3) is a distance between the center of the electronic circuit component 5 and the outer surface of the lateral side of the case upper portion 2A in the X direction orthogonal to the Y direction. Therefore, since the electronic circuit component 5 of the mouse 1 is equally spaced from any one of the horizontal directions as viewed in the X direction, the electronic circuit component 5 is disposed at the center position (central portion) of the housing 2 of the mouse 1 in the X direction.

As described above, in the mouse 1 according to embodiment 1, the lens 4 and the electronic circuit component 5 are spaced as far as possible from each other as possible in the positional relationship between the lens 4 of the opening R1, the electronic circuit component 5 on the substrate 10, and the image sensor 15 in a plan view of the horizontal plane. That is, as described above, in fig. 2 and 3, the electronic circuit component 5 is disposed at a position where the distance between the center of the electronic circuit component 5 and the lower right side surface of the housing upper portion 2A is K4A in the vicinity of the end portion of the housing 2 on the right side in the longitudinal direction. On the other hand, the opening R1 and the lens 4 provided in the opening are disposed at a position where the distance between the vicinity of the left end portion, which is the opposite side in the longitudinal direction of the housing 2, and the lower left side surface of the housing upper portion 2A with respect to the electronic circuit component 5 is K6. As a result, the opening R1 and the horizontal distance between the lens 4 and the electronic circuit component 5 are separated by the distance K7, but the distance K7 is preferably as large as possible in order to prevent high heat or the like entering the housing 2 through the opening R1 and the lens 4 from reaching the electronic circuit component 5 that cannot receive heat or the like. In embodiment 1, since the opening R1 and the distance K7 between the lens 4 and the electronic circuit component 5 are arranged as large as possible, and the opening R1 and the lens 4 are spaced apart from the electronic circuit component 5 to the maximum extent in the horizontal direction and the vertical direction from each other, even when the mouse 1 is subjected to a sterilization treatment by high-temperature and high-pressure water vapor in an autoclave device, for example, damage or failure of the electronic circuit component 5 and the image sensor 15 due to heat, pressure, and moisture entering the inside of the mouse 1 through the opening R1 and the lens 4 reaching the electronic circuit component 5 or the image sensor 15 can be prevented to the maximum extent, and the electronic circuit component 5 and the image sensor 15 that cannot receive heat or the like can be protected to the maximum extent.

In addition to the structure in which the opening R1 and the lens 4 are spaced from the electronic circuit component 5 in the vertical direction in the Z direction and the Y direction in the horizontal direction in embodiment 1, as shown by the two-dot chain line in fig. 3, for example, the opening R1 and the lens 4 or the electronic circuit component 5 may be disposed so as to be spaced apart from the center position in the longitudinal direction of the mouse 2 by being shifted in either the Y direction in the horizontal direction or the X direction in the horizontal direction. Thus, the electronic circuit component 5, the opening R1, and the lens 4 are spaced apart from each other in all directions of the Z-direction vertical direction, the horizontal direction Y direction, and the horizontal direction X direction. As a result, the distance separating the electronic circuit component 5 from the opening R1 and the lens 4 is maximized in three dimensions in all directions of the Z direction, the Y direction, and the X direction, and heat and moisture entering the mouse 2 from the portion of the opening R1 and the lens 4 can be prevented from reaching the electronic circuit component 5 to the maximum.

In this case, the positions of the opening R1 and the lens 4 or the electronic circuit component 5 shifted in the X direction are set to be diagonal directions to each other, that is, the positions of the opening R1A and the lens 4A and the electronic circuit component 5B or the opening R1B and the lens 4B and the electronic circuit component 5A in fig. 3 are set to be opposite sides in the X direction, and the openings are spaced apart from each other in the diagonal directions to the maximum extent in all directions of the Y direction in the Z direction, the vertical direction, the horizontal direction, and the X direction in the horizontal direction, and therefore, the distance between the opening R1 and the lens 4 or the electronic circuit component 5 becomes maximum in the Z direction, the Y direction, and the X direction, and the electronic circuit component 5 which cannot receive heat can be protected to the maximum extent.

As described above, in embodiment 1, as shown in fig. 3, not only is the planar shape of the substrate 10 formed in a substantially elliptical shape similar to the substantially elliptical shape of the inner surface of the structure surface of the housing 2, but also the distance from the structure surface of the housing 1 is made as uniform and large as possible over the entire circumference of the substrate 10, and heat or the like entering from the outside through the structure surface of the housing 2 is prevented as much as possible, and the area of the substrate 10 is made as small as possible, so that the heat accumulated in the substrate 10 is not conducted to the electronic circuit components 5 or the like by heat conduction, and it is devised to prevent heat conduction as follows.

In embodiment 1, in order to prevent heat conduction to the electronic circuit component 5 and the image sensor 15 through the substrate 10 as much as possible, the end faces in the longitudinal direction and the short direction of the substrate 10 are also arranged spaced apart from the outer surface of the case upper portion 2A of the case 2 of the mouse 1. That is, as shown in fig. 3, the distance in the horizontal direction of the substrate 10 in the Y direction is distances K4C1 and K4C2 from end faces (right end face and left end face in fig. 3) in the longitudinal direction (front-rear direction) of the substrate 10 in fig. 3 to outer surfaces on the right side and left side in the longitudinal direction of the case upper portion 2A, respectively.

Further, as the distance in the horizontal direction of the substrate 10 in the X direction (the short side direction of the case 2 of the mouse 1 in fig. 3, that is, the opposite side and the near side in the left-right direction when viewed from the right to the left in fig. 3) orthogonal to the Y direction, the distances K4D1 and K4D2, which are the distances from the side surfaces (the end surface on the opposite side and the end surface on the near side in fig. 3) in the short side direction of the substrate 10 in fig. 3 to the outer surfaces on the right side (the opposite side in fig. 3) and the left side (the near side in fig. 3) in the short side direction of the case upper portion 2A of the case 2 of the mouse 1, are respectively separated. The distances K4C1 and K4C2 are equal to each other and the distances K4D1 and K4D2 are equal to each other, so that the balance of heat resistance and the like is good, but they may be different depending on the structure, arrangement of components, use conditions, and the like of the outside and inside of the housing 2 of the mouse 1.

Therefore, in addition to the planar shape of the board 10 forming a substantially elliptical shape similar to the substantially elliptical shape of the inner surface of the structure surface of the housing 2 as shown in fig. 3, the board 10 in embodiment 1 is separated from the outer surface of the housing bottom 2B of the housing 2 of the mouse 1 by the distance K1 (see fig. 2), and as shown in fig. 3, the board 10 is separated from the structure surface of the housing 2 of the housing 1 not only in the vertical direction but also in the horizontal direction by the distances K4C1 and K4C2, and the distances K4D1 and K4D2, respectively, so that the board 10 is separated from the structure surface of the housing 2 of the mouse 1 as much as possible in the vertical direction, and heat conduction from the housing top 2A and the housing bottom 2B of the housing 2 of the mouse 1 to the board 10 and heat accumulation in the board 10 can be suppressed to the maximum extent. As a result, heat conduction from the high-quality substrate 10 to the low-quality electronic circuit component 5, the light source unit 7, the power supply unit 8, the image sensor 15 via the electronic circuit component 5, and the like is minimized, and damage, failure, and deterioration of the electronic circuit component 5, the image sensor 15, and the like due to high temperature can be effectively prevented.

The distance K5 is the distance between one end (left end in fig. 2) of the board 10 and the outer surface of the case upper part 2A closest to the one end. That is, the substrate 10 is spaced apart from the outer surface of the upper housing portion 2A by a distance K5. In this case, in embodiment 1, since the planar shape of the substrate 10 is formed in a substantially elliptical shape similar to the substantially elliptical shape of the inner surface of the structural surface of the housing 2, and both end surfaces in the longitudinal direction of the substrate 10 are not linear shapes but are curved surfaces in an arc shape, the distance K5, which is the distance between both end surfaces in the longitudinal direction of the substrate 10 and the inner surface of the structural surface of the housing 2, that is, the length of the distance K5, can be as large as possible over the entire length of both end surfaces, as compared with the case of the substrate 10 in which both end surfaces are linear shapes. Accordingly, since the distance K5 between the substrate 10 and the outer surface of the case upper 2A is sufficiently ensured, heat conduction from the surface of the case upper 2A to the end of the substrate 10 can be prevented.

[ preferred examples of distances K1 to K7, etc. ]

Here, a preferred example of the dimensions such as the distances K1 to K7 is described, and first, in an example in which the height of the entire mouse 1 is 30 to 50mm (preferably, for example, 40mm), the length of the entire mouse is 80 to 130mm (preferably, for example, 110mm), and the width of the entire mouse is 45 to 75mm (preferably, for example, 55 to 65mm), in this case, although the thicknesses of the substrate 10, the housing 2, and the housing bottom 2B are also considered, the distances K1 are 10 to 25mm (preferably, for example, 12 to 20mm), K2 are 5 to 20mm (preferably, for example, 7 to 15mm), K3 is 20 to 35mm (preferably, for example, 12 to 25mm), K4A is 15 to 50mm (preferably, for example, 20 to 30mm), K4B is 22.5 to 37.5mm (half the width of the mouse), K4C1 is 9 to 30mm (preferably, 2K 3 to 50 mm), K4K 3 to 20mm (preferably, for example, K3 to 37.5 mm), and K3 to 37.5mm (preferably, for example, 75mm), K3 to 20mm (preferably, for example, 9 to 15mm), and K3 to 15mm (preferably, for example, 75mm), and K3 to 20, Specific dimensions such as K5-90 mm (preferably 45-85 mm, for example), K6-8-50 mm (preferably 10-20 mm), and K7-30-90 mm (preferably 60-80 mm) are considered as preferable dimensions of each of them.

It is to be understood that the above dimensions are not limited to the above examples, and may be varied in various ways depending on the dimensions of the mouse 1, the case 2, the electronic circuit component 5, the substrate 10, and the like.

By setting the dimensions of K1 to K7 to the above-described respective dimensions, in particular, K1 and K2 to the above-described dimensions, and further, by setting the dimensions of K4A, K6, and K7, in particular, K7 to be as large as possible, even in the case where the mouse 1 is subjected to sterilization treatment by high-temperature and high-pressure water vapor in the autoclave device, the distances K1, K2, and K7 are particularly secured, so that it is possible to prevent the influence of the high-temperature and high-pressure water vapor and moisture from reaching the electronic circuit component 5, and it is possible to protect the electronic circuit component 5 and the like from damage or failure due to the high-temperature and high-pressure water vapor.

In addition to the above-described respective dimensions of the distances K1 to K7, the ratio of the distances K1 to K7 is also an important element for obtaining the operational effect (protection of the electronic circuit component 5, etc.) of the present invention. As the preferable ratio confirmed by the present inventors, the relationship of K1> K2, K1 ≈ or ≦ K3 is considered for the mutual K1 to K7. Based on this ratio, when the ratios of the distances K1 to K5 are represented numerically, K1: k2: k3: K4A: K4B: k5 ═ 3: 2: 4: 5: 5: a ratio of 11 to 14, K4A: k6: ratio of K7, 2: 1: a ratio of 6 is considered to be a preferred ratio.

By setting the ratios of the distances K1 to K7 to the above ratios, even when the mouse 1 is subjected to sterilization treatment by high-temperature and high-pressure water vapor in the autoclave device, the distances K1 and K2 are particularly ensured, so that it is possible to prevent the influence of the high-temperature and high-pressure water vapor and moisture from being transmitted to the electronic circuit component 5, and to protect the electronic circuit component 5 from damage or failure due to the high-temperature and high-pressure water vapor.

Moreover, of the above ratios, particularly the ratio of the overall height of the mouse 1 to the distance K1 is important to the present invention. For example, when the entire height of the mouse 1 is set to 40mm, the dimension of the distances K1 to K7 and the ratio therebetween are set to an optimum ratio, and even when the mouse 1 is exposed to severe processing conditions such as an autoclave processing, it is very advantageous that the sterilization processing by the high-temperature and high-pressure water vapor can be endured.

As described above, in the mouse 1 according to embodiment 1, the electronic circuit component 5 to be protected from high heat or the like can secure a distance of K1 to K7 from any direction, and the arrangement position is selected so that heat or the like from the outside of the mouse 1, particularly heat entering the mouse 1 from the opening R1 and the lens 4, is not conducted to the electronic circuit component 5. The arrangement position of the electronic circuit component 5 and the like is not limited to that of embodiment 1, and may be any arrangement position, and may be selected in consideration of necessary heat resistance and the like.

With the above configuration, in the mouse 1 according to embodiment 1, adverse effects such as heat from the outside are less likely to be transmitted to the electronic circuit components 5 and the like on the substrate 10 during the sterilization process. Thus, the mouse 1 according to embodiment 1 can protect the electronic circuit component 5 and the like from damage or failure due to high temperature and high pressure or water vapor, and can withstand sterilization treatment by high temperature and high pressure water vapor in an autoclave device and the like.

In embodiment 1, the opening R1 of the case bottom portion 2B is a minimum opening in order to minimize heat and water (steam) intrusion during sterilization treatment and facilitate waterproofing and pressure resistance. Since the mouse 1 uses the optical fiber 6f as the transmission unit 6, the area of the opening R1 in which the lens 4 is provided can be reduced. The area and volume of the opening R1 and the lens 4 are set to be sufficient for drawing the image light, and are minimized. The width H1 indicates the width of the opening R1 and the lens 4 in the Y direction. The lens 4, the sealing material, and the like are fixed to the opening R1 so as not to enter a gap of moisture. This improves the heat resistance, water resistance, pressure resistance, and the like of the sterilization treatment at the opening R1. Further, if the occupied area of the opening R1 is reduced, the number of other members can be increased, and the function can be improved.

In fig. 2, the substrate 10 and the like are disposed in the illustrated positions in the internal space of the housing 2 by an arbitrary mechanism. The substrate 10 may be physically connected to the housing 2, or may be not connected thereto, and may be accommodated in the housing 2 only so that the position thereof can be changed. In the configuration example of fig. 2, the substrate 10 is not connected to the case 2. The board 10 may be mounted above the object disposed in the first space SP1, which will be described later.

In the mouse 1, the lens 4 is disposed in a space (first space portion SP1) located at a distance K2 downward from the lower surface of the substrate 10 located on the lower side in the Z direction, and the electronic circuit component 5 and the like are disposed on the upper surface of the substrate 10 located on the upper side in the Z direction. The optical fiber 6f of the transmission section 6 extends from the lens 4 to the electronic circuit component 5, passing through the side surface of the substrate 10 and wrapping around. Accordingly, the opening R1 and the lens 4 of the case bottom 2B are spaced apart from the electronic circuit component 5 by the distance K7 in the horizontal direction and are spaced apart from the electronic circuit component 5 by the distance K1 or K2 in the vertical direction, that is, by a sufficient thermal separation distance, so that heat conduction from the opening R1 and the lens 4 to the electronic circuit component 5 is difficult, and the electronic circuit component 5 can be protected from damage or failure.

In addition, not only the conveying unit 6 but also other members may be disposed in the first space portion SP 1. In this space, particularly, a wireless charging section can be arranged as the power supply section 8, and therefore, in this case, the performance of wireless charging is easily improved. In the case of the wireless communication system or the wireless charging system, a wired cable or a mechanism including an opening portion therefor is not required, and therefore, the sterilization treatment is more advantageous.

Further, since the optical fiber 6f is applied to the mouse 1, there is an advantage that the degree of freedom of the arrangement of the lens 4, the image sensor 15, and the like is increased and the accuracy of the installation position of the arrangement of the lens 4, the image sensor 15, and the like is not so high. In the mouse 1, the electronic circuit component 5, the image sensor 15, and the like may be arranged at appropriate positions, distances, orientations, and the like with respect to the position of the lens 4 of the opening R1 in consideration of heat resistance and the like.

The optical fiber 6f and other wiring (for example, the wiring 3c of the button 3, the wiring 7c of the light source unit 7, the wiring 8c of the power supply unit 8, etc.) may be of a type having heat insulation properties, and a fourth heat insulating layer described later may be provided.

[1-3: mouse plane constitution

Fig. 3 shows an outline of the mouse 1 according to embodiment 1 when viewed from above in a horizontal plane (X-Y plane). Fig. 3 shows a structure at a position where the substrate 10 exists, particularly in the Z direction. In this example, the housing 2 and the like have a substantially bilaterally symmetric shape. One end of an optical fiber 6f as a transmission unit 6 is connected to the lens 4 of the opening R1 disposed at a distance K6 from the left end side surface of the upper housing portion 2A of the mouse 1 (fig. 2 and 3). The mouse 1 according to embodiment 1 has a wireless communication function, but may have a wired communication function. In this case, an opening through which the wired communication cable passes is required in the housing 2, and measures such as heat insulation and water resistance are taken in the opening.

[1-4: mouse cross section

Fig. 4 shows an outline of a cross section (X-Z plane corresponding to line B-B in fig. 1) of the mouse 1 according to embodiment 1. In this example, the transmission unit 6 is a wiring passing through the space on the front side in the housing 2 and the second space SP2, but may be another wiring described later. As a configuration of this wiring, the optical fiber 6f extends upward in the Z direction from the position of the lens 4 of the opening R1 in the first space SP1 and the space on the front side in the housing 2, and reaches a position above the substrate 10. From this position, the optical fiber 6f extends rearward in the Y direction above the substrate 10 in the second space portion SP2, and reaches the electronic circuit component 5 at the rear on the substrate 10. Then, the other end of the optical fiber 6f is connected to the upper side of the image sensor 15 on the electronic circuit part 5.

The housing 2 is configured by, for example, joining the housing upper portion 2A and the housing bottom portion 2B. In the Z direction, a position SZ1 shows an example of the engagement position of the case upper part 2A and the case bottom part 2B. The position SZ1 is arbitrary in three dimensions and is not limited. In this example, the substrate 10 is disposed above the position SZ1, but the present invention is not limited thereto. The position SZ1 may be different depending on the position of the outer periphery of the casing 2, that is, may be a curved joint surface. The case 2 is not limited to this, and may be formed of three or more parts. In addition, a heat insulating material or a sealing material is provided near the joint position of the case upper portion 2A and the case bottom portion 2B for heat insulation and water resistance, thereby improving the heat insulation and water resistance. The housing 2 is made of a material having predetermined properties (first properties) including heat resistance, heat insulation, water resistance, pressure resistance, and the like, which will be described later.

[1-5: image sensor

Fig. 5 shows an example of the connection configuration of the electronic circuit component 5 and the image sensor 15 to the optical fiber 6f of the transmission unit 6 in embodiment 1. (A) This is a first example and shows a detailed part of fig. 2. (B) Is a second example and is a modification. (C) Is the third example and is a modification.

In (a), the electronic circuit component 5 is mounted on the upper surface of the substrate 10 in the Z direction. An image sensor 15 is mounted on the upper surface of the electronic circuit component 5. The other end of the optical fiber 6f is connected to the upper surface of the image sensor 15. A plurality of pixels (light receiving elements) are formed on the upper surface of the image sensor 15. The image sensor 15 receives image light from the optical fiber 6f and converts the image light into data of a pixel value of each pixel. The electronic circuit unit 5 receives the image signal from the image sensor 15 and performs the above-described calculation.

In (B), the electronic circuit components 5 are mounted on the lower surface of the substrate 10 in the upper and lower sides in the Z direction. An image sensor 15 is connected to a lower surface (an upper surface when viewed from the electronic circuit component 5) of the electronic circuit component 5. The other end of the optical fiber 6f is connected to the lower surface (upper surface when viewed from the image sensor 15) of the image sensor 15.

In (C), the electronic circuit component 5 is mounted on the upper side of the through hole portion R2 provided in a part of the substrate 10. The electronic circuit component 5 is mounted integrally with the image sensor 15 on the lower surface side. Then, the other end of the optical fiber 6f is connected to the lower surface of the image sensor 15.

The connection mode of the transmission unit 6 to the electronic circuit component 5 or the image sensor 15 is not limited to these, and may be any. The electronic circuit part 5 and the image sensor 15 may be configured integrally.

[ description of an example in which the mouse of the present embodiment is applied to an autoclave sterilization treatment ]

An outline of a case where the mouse according to the present embodiment is applied to an autoclave process, which is one type of sterilization process in a medical field, will be described with reference to fig. 25. Here, the autoclave apparatus Y1 is an apparatus for performing autoclave processing on a sterilized object. The autoclave apparatus Y1 includes a pre-vacuum system. In this example, the object to be sterilized is the mouse 1 of embodiment 1, which is a used mouse used in a medical field or the like. The autoclave apparatus Y1 accommodates the mouse 1 as the object Y3 to be sterilized in the internal space (in other words, the sterilization chamber) Y2 of the pressure-resistant container. During the sterilization treatment, the internal space Y2 is filled with high-temperature and high-pressure water vapor, and the object Y3 is exposed to the water vapor for a predetermined time or more. The autoclave apparatus Y1 controls the temperature, pressure, time, and the like according to the setting. The autoclave device Y1 includes an electric heater, for example, and may generate infrared rays.

In the medical field, infection countermeasures based on standard preventive strategies are important. Standard preventive strategies include cleaning, disinfecting, and sterilizing medical instruments. Cleaning refers to removing foreign matter from an object. Sterilization refers to the removal of all or most of the microorganisms other than bacterial spores from an object. Sterilization refers to the complete removal or killing of microorganisms. The degree of cleaning, disinfection, and sterilization is different depending on the object. Bacteria and the like can be killed to some extent but not completely by cleaning and disinfection. Since the medical mouse is operated by hand, a measure to a certain extent is required. In the prior art, only the disinfection of the surface of the mouse is achieved, and the mouse cannot be sterilized.

The sterilization includes autoclaving, gas sterilization, chemical sterilization, etc. Since the autoclave has high operability of sterilization and no residual toxicity, it is most widely used as the safest and reliable method for sterilizing an object to be sterilized under the sterilization treatment conditions. The pre-vacuum system in the autoclave device of class B is a system in which a vacuum state is formed in the internal space Y2 during the steps of sterilization and drying, and is effective for objects of all shapes. The procedure in the sterilization treatment example is as follows. The flow sequentially includes a step YS1 of preparing for cleaning and removing the adhering substance, a step YS2 of cleaning, a step YS3 of drying, a step YS4 of packaging, and a step YS5 of sterilizing. The cleaning step YS2 is performed by, for example, dipping in a detergent. The packaging step YS4 is a step of packaging the mouse 1 as a sterilization target with a sterilization bag.

When the autoclave sterilization treatment of class B was performed using the autoclave apparatus Y1 of the prevacuum system, the sterilization process YS5 further includes the following process. The process YS5 includes a vacuum and steam supply process YS11, a pressurization and heating process YS12, a sterilization process YS13, a reduced pressure and steam exhaust process YS14, and a drying process YS 15. The vacuum and steam supply process YS11 is a process of extracting air from the internal space Y2 and filling the entire space with saturated water vapor. The pressing and heating process YS12 is a process of pressing and heating the internal space Y2. The sterilization process YS13 is a process of: as an example of the conditions, the temperature of the water vapor in the internal space Y2 is maintained at a predetermined temperature within a range of 121 to 137 ℃, and the pressure is maintained at a predetermined pressure within a range of 2 to 2.2 atmospheres (2.1 atmospheres in the example of fig. 25), and the treatment is performed for a predetermined time, for example, 20 minutes or more. The pressure reducing/steam discharging step YS14 is a step of reducing the pressure in the internal space Y2 and discharging the steam.

The mouse 1 as the object Y3 to be sterilized is required to have a performance of withstanding high-temperature and high-pressure water vapor and the like in the sterilization process YS13 and the drying process YS15, and the mouse 1 of the present embodiment has the performance sufficiently. By the flow including the sterilization step YS5, the germs adhering to the mouse as the object Y3 were killed. After the treatment, the object Y3 was taken out of the autoclave apparatus Y1 and stored.

Steam at a predetermined temperature and pressure during sterilization treatment is not endurable because a case and electronic circuit components included in a mouse for general computer input and operation are damaged or deteriorated. In the mouse 1 of embodiment 1 and the like, the structure including the housing and the electronic circuit components is designed to be heat-resistant, heat-insulating, water-resistant, waterproof, pressure-resistant, and the like so as to be able to withstand water vapor at a predetermined temperature and pressure during sterilization treatment. The mouse 1 according to embodiment 1 uses as few members as possible made of a material (e.g., a general plastic) that does not generate heat, and in the case of use, measures such as a heat insulator are combined. The mouse of embodiment 1 has properties such as heat insulation, heat resistance, water resistance, and pressure resistance at predetermined levels, and thus can withstand any of the above-described cleaning, sterilization, and disinfection. The mouse 1 of embodiment 1 may have a structure capable of withstanding a sterilization process of a lower degree, but more preferably has a structure capable of withstanding an autoclave sterilization process of class B.

[1-6: effects and the like

(a) As described above, the mouse 1 according to embodiment 1 is configured such that: the lens 4 of the housing bottom portion 2B, the electronic circuit component 5 of the substrate 10, and the image sensor 15 are spaced apart by distances K1 and K2 in the vertical direction and by a distance K7 in the horizontal direction, so that heat or the like entering the mouse 1 from the opening R1 and the portion of the lens 4 is prevented from reaching the electronic circuit component 5 and the image sensor 15 to the maximum extent. Thus, the mouse 1 can withstand sterilization by high-temperature and high-pressure steam even when exposed to severe processing conditions such as autoclave processing. As a result, the use environment of the computer system including the mouse 1 can be expanded to a medical field or the like. In particular, in the medical field, a system including a sterilized mouse is used, making it possible to perform advanced medical treatment, surgery, and the like.

(b) In embodiment 1, as described above and shown in fig. 2 and 3, the electronic circuit component 5, the light source unit 7, and the power supply unit 8 are all disposed above the substrate 10. As a result, even when the mouse 1 is subjected to sterilization treatment by high-temperature and high-pressure water vapor in the autoclave device, the electronic circuit component 5, the light source unit 7, and the power supply unit 8 are all separated from the case bottom portion 2B by a distance K1 or more, whereby the influence of high temperature, high pressure, and moisture due to the high-temperature and high-pressure water vapor can be prevented from being transmitted to all of the electronic circuit component 5, the light source unit 7, and the power supply unit 8, and all of the electronic circuit component 5, the light source unit 7, and the power supply unit 8 can be protected from damage or failure due to the high temperature, high pressure, and water vapor.

(c) In addition, in embodiment 1, as shown in fig. 3, the planar shape of the substrate 10 is formed in a substantially elliptical shape similar to the substantially elliptical shape which is the shape of the inner surface of the structure surface of the housing 2, so that the distance from the inner surface of the structure surface of the housing 1 is largely divided as uniformly as possible over the entire circumference of the substrate 10, whereby heat entering from the outside through the structure surface of the housing 2 can be prevented as much as possible, and the area of the substrate 10 is reduced as much as possible by forming the substrate in a substantially elliptical shape, so that heat accumulated in the substrate 10 is not conducted to the electronic circuit components 5 and the like by heat conduction. As a result, even if the planar shape of the substrate 10 is a surface designed with a careful design, it is possible to prevent heat from accumulating in the substrate 10 and heat from being conducted to the electronic circuit component 5 and the image sensor 15, and to prevent damage and failure of the electronic circuit component 5 and the image sensor 15 due to thermal attack as much as possible.

(d) In the mouse according to embodiment 1, by setting the ratio of the distances K1 to K7 to the above ratio, even when the mouse 1 is subjected to sterilization treatment by high-temperature and high-pressure water vapor in the autoclave device, by securing the distances K1 and K2 in particular, it is possible to prevent the influence of high temperature, high pressure, and moisture due to the high-temperature and high-pressure water vapor from being transmitted to the electronic circuit component 5, and to protect the electronic circuit component 5 from damage or failure due to the high temperature, high pressure, and water vapor.

(e) Further, according to the mouse of embodiment 1, the lens 4 of the case bottom portion 2B is arranged to be spaced apart from the electronic circuit component 5 and the image sensor 15 of the substrate 10 via the transfer portion 6, whereby the electronic circuit component 5 and the like can be arranged appropriately, and the electronic circuit component 5 and the like can be protected from the external heat and water.

(a) The structure in which the light source unit 7 is not provided is as follows. In this configuration, as a light source for detecting an image, illumination light of the use environment of the mouse 1 or the like is used. The illumination light may be, for example, light emitted from a mouse pad. Since there is a gap between the housing bottom 2B and the installation surface SF, illumination light enters from the gap.

(b) The structure in which the substrate 10 includes the plurality of electronic circuit components 5 is as follows. In this example, the electronic circuit component 5a and the electronic circuit component 5b are mounted on the upper surface of the substrate 10. The plurality of electronic circuit components 5 are objects to be protected against heat and water. Therefore, the electronic circuit component 5a is disposed at a position near the center, for example, in the case 2. On the other hand, in fig. 6, the opening R1 and the lens 4 are disposed near the left end of the case bottom portion 2B, and the electronic circuit component 5 is disposed apart from the opening R1 and the lens 4 in both the horizontal direction and the vertical direction. The electronic circuit part 5a is a part constituting a controller of the mouse function, and is also mounted with an image sensor 15. The electronic circuit component 5b is a part constituting a wireless communication function, and is disposed, for example, at a position forward in the Y direction. The controller of the electronic circuit part 5a processes the image signal from the image sensor 15 to calculate the state of the mouse 1, and processes the input of the button 3 to control the wireless communication function of the electronic circuit part 5b to perform communication with the outside. The arrangement position of each electronic circuit component 5 may be selected as appropriate in consideration of heat resistance and the like. The wireless communication circuit of the electronic circuit part 5b transmits data relating to the state of the mouse 1 to an external computer or the like. The present invention is not limited to the wireless communication method, and may be applied to an infrared method, a Bluetooth (registered trademark), or the like.

Further, the plurality of electronic circuit components 5a and 5B may be arranged as shown in fig. 6(B) so as to be spaced apart not only in the Y direction but also in the X direction.

(c) The power supply section 8 is constituted by the secondary battery 8A and the wireless charging section 8B as follows. The wireless charging unit 8B is configured by a circuit such as a power receiving coil, for example, and receives power supply from a wireless power supply unit (such as a power transmission coil) such as an external mouse pad by an electromagnetic induction method or the like, and charges the secondary battery 8A with the power supply through the wiring 8 c. In this example, the wireless charging unit 8B is disposed at a position behind the upper surface of the case bottom portion 2B, and the secondary battery 8A is disposed at a position behind the upper surface of the substrate 10. When the secondary battery 8A is a member that does not receive heat, it is disposed at a position away upward from the case bottom portion 2B, as in the case of the electronic circuit component 5. Since the wireless charging unit 8B is disposed in the first space portion SP1 between the case bottom portion 2B and the substrate 10, a wide area, that is, the wireless power feeding efficiency can be easily increased.

As a modification, the wireless charging unit 8B may be a type of power supply unit that is exposed to the outer surface of the case bottom portion 2B, or may be a type of power supply unit that has contact terminals exposed to the outer surface of the case bottom portion 2B. In this case, for example, a cover having heat insulation and water resistance is provided for the exposed portion. The shape of any member exposed to the outer surface of the housing 2 may be a concave portion or a convex portion, but it is preferable that the member is smooth with respect to the outer surface of the housing 2. The composition is smooth, and thus has anti-contamination and easy-to-clean properties.

(d) The structure of the push-button 3 is of the lever type, in other words the way of a physical switch, as described below. The push button 3 is provided to have a continuous curved surface with respect to the outer surface of the housing upper portion 2A at a forward position of the outer surface of the housing upper portion 2A. The push button 3 is made of, for example, hard resin, and is displaced in the vertical direction by a pressing operation by a user. On the lower side of the push button 3, a rod 3d is fixed in a projecting manner. The rod 3d is displaced in the vertical direction in accordance with the displacement of the push button 3. A switch 3e is provided at a position in front of the upper surface of the base plate 10 so as to match the position of the lever 3 d. Corresponding to the downward displacement of the lever 3d, is in physical contact with the switch 3 e. Thereby, the circuit within the switch 3e is changed from the off state to the on state. The switch 3e is connected to the electronic circuit component 5a through the circuit of the substrate 10. The controller of the electronic circuit unit 5a processes the input of the on/off signal from the switch 3e to grasp the operation state of the push button 3. Further, measures such as heat insulation property described later may be applied to the lever 3d and the switch 3 e. The structure of the push button 3 is arbitrary and is not limited, and any measure against heat resistance and water resistance can be implemented near the push button 3.

(e) The housing 2 has a substrate support portion as follows. In this example, the support portion 2C is provided so as to extend upward from a part of the case bottom portion 2A. (B) In the case bottom 2B, support portions 2C are provided at four locations corresponding to four locations on the front, rear, left, and right of the substrate 10. The support portion 2C has a lower end supported by the case bottom portion 2B and an upper end supporting the substrate 10. Thus, the substrate 10 is disposed at a predetermined position in the housing 2, that is, at a position as far as possible apart from the surface of the housing 2. The substrate 10 may be fixed to the support 2C or may be placed only on the support 2C. The support portion 2C may be formed of a member such as a screw as a fixing mechanism. The position of the support portion 2C is not limited. As a modification, the supporting portions 2Cb, 2Cc are shown (fig. 6). The support portion 2Cb is provided to extend horizontally from a side surface of the housing upper portion 2A, and supports the substrate 10 at a front end. The support portion 2Cc is provided to extend downward from the upper surface portion of the housing upper portion 2A, and the substrate 10 is fixed to the front end. The support portion 2C is preferably made of a heat insulating material, or measures such as heat insulation described later may be applied to the support portion 2C.

As another configuration example, a pressure adjustment mechanism may be provided in the housing 2. Since high temperature and high pressure are applied to the casing 2 at the time of the sterilization treatment, it is more preferable to provide a pressure adjustment mechanism for adjusting the pressure in the casing 2. The pressure adjusting mechanism may be a pressure adjusting valve or the like. The button 4 and the opening R1 may be provided with a pressure adjustment mechanism.

< embodiment 2>

A mouse according to embodiment 2 of the present invention will be described with reference to fig. 7 to 18. The following describes the components of embodiment 2 and the like that are different from embodiment 1. The mouse of embodiment 2 is configured to have a thermal insulation and waterproof structure in addition to the structure of the mouse of embodiment 1.

In the configuration example of the mouse according to embodiment 2 shown in fig. 7 and the like, a multi-layer heat insulating structure (in other words, a sealed heat insulating structure) is added to the mouse according to embodiment 1 shown in fig. 2 and the like as a basic and common structure. The insulation construction has multiple layers or layers of insulation material. The mouse has a multi-layer heat insulating structure to a degree of heat resistance required depending on the use environment (environmental change depending on the degree of sterilization or disinfection performed in the medical field). In addition, when the required heat resistance or the like may be lower, a modification in which only a part of the heat insulating layer is provided is omitted, and the like is also possible.

The opening R1 and the lens 4 in embodiment 2 are disposed at the front side of the mouse 1, that is, at a position near the left end of the housing bottom portion 2B as viewed in fig. 7 and the like, and are configured to be spaced apart from the electronic circuit component 5 in the horizontal direction to the maximum extent, for example, as in embodiment 1. The opening R1, the lens 4, the electronic circuit component 5, and the like may be disposed at positions different from those of embodiments 1 and 2 depending on the use environment, use conditions, and the like of the mouse 1.

[2-1: mouse and Wiring example 1

Fig. 7 (a) shows a vertical cross section of a mouse 1 as a mouse according to embodiment 2, and (B) shows a planar configuration. The mouse 1 has a plurality of heat insulating layers as a whole, in addition to the same components as those of fig. 2. The heat insulation construction including the plurality of heat insulation layers roughly has a first heat insulation layer 21, a second heat insulation layer 22, a third heat insulation layer 23, a fourth heat insulation layer 24, and a fifth heat insulation layer 25. The properties of the respective heat insulating layers may be the same or different.

(1) The first thermal insulation layer 21 is a casing thermal insulation material, and is disposed in contact with the surface (outer surface or inner surface) of the casing 2. In this example, the first thermal insulation layer 21 is provided in contact with the inner surface of the casing 2. When the first thermal insulation layer 21 is provided on the outer surface of the case 2, it may be a cover having thermal insulation properties, a coating, or the like. The case 2 may be formed in multiple layers as an outer case and an inner case described later, and in this case, the first thermal insulation layer 21 may be formed as one of the outer case and the inner case, or may be a layer sandwiched between the outer case and the inner case. Alternatively, a coating or a material may be disposed between the outer surface and the inner surface of the outer casing, the outer surface and the inner surface of the inner casing, and the outer casing and the inner casing so as to have a heat insulating function.

(2) The second heat insulating layer 22 is a substrate heat insulating material and is disposed so as to surround the substrate 10 in all directions at a position separated from the case 2. In other words, the substrate 10 is accommodated in the second heat insulating layer 22. A third space SP3 is formed in the second heat insulating layer 22. The second heat insulating layer 22 is disposed inside the casing 2 and the first heat insulating layer 21. The second heat insulating layer 22 is not in contact with the first heat insulating layer 21 but has a space therebetween.

(3) The third heat insulating layer 23 is an independent member heat insulating material and is disposed to cover independent members such as the electronic circuit member 5, the secondary battery 8A, and the wireless charging unit 8B. The third heat insulating layer 23 provides a member which does not receive heat as a protection object. The third heat-insulating layer 23 may be provided in the light source unit 7, or the third heat-insulating layer 23 of the cordless charging unit 8B may be omitted. The third heat insulating layer 23 may be provided so as to surround the entirety of the individual member. The third heat insulating layer 23 of the wireless charging unit 8B covers the upper surface side of the wireless charging unit 8B, but may cover the entire surface including the lower surface side, and when it is disposed below the substrate 10, it can also perform an important function of supporting or fixing the substrate 10. In the case where the component itself such as the electronic circuit component 5 has sealing properties and heat insulating properties (for example, a sealing member), the third heat insulating layer 23 may be omitted.

(4) The fourth heat insulating layer 24 is a wiring insulator and is disposed so as to cover the optical fiber 6f of the transmission unit 6, the wiring 3c of the push button 3, the wiring 8c of the power supply unit 8 (the secondary battery 8A and the wireless charging unit 8B), the wiring 7c of the light source unit 7, the wiring 7d of the light source unit, and the like. In the case where the wiring itself has heat resistance or the like, the fourth heat insulating layer 24 of the wiring may be omitted.

(5) The fifth heat insulating layer 25 is a spacer heat insulating material, and is disposed in the first space SP1 between the case bottom portion 2B and the substrate 10 and the second heat insulating layer 22, for example, in contact with the first heat insulating layer 21 and the second heat insulating layer 22. In particular, the fifth heat insulating layer 25 is disposed centered at a position below the center of the electronic circuit component 5, and thus, the heat insulating effect on the electronic circuit component 5 can be improved. The fifth heat insulating layer 25 may be disposed so as to cover the transfer portion 6, the fourth heat insulating layer 24 thereof, and the like. Thus, the second thermal insulation layer 22 including the substrate 10 is placed and supported on the upper side of the fifth thermal insulation layer 25. Thereby, the substrate 10 and the like are positioned. That is, the fifth thermal insulation layer 25 can perform an important function of supporting and/or fixing the substrate 10 when it is disposed below the substrate 10, in addition to a function as a spacer. The second heat insulating layer 22 may be fixed to the fifth heat insulating layer 25.

The optical fiber 6f of the transmission unit 6 enters the third space SP3 in the second heat-insulating layer 22 through, for example, the opening Q1 in a part of the upper surface side of the second heat-insulating layer 22, and is connected to the electronic circuit component 5 and the like. The wiring 3c from the push button 3 enters the third space SP3 through the opening Q2 of a part of the second heat insulating layer 22, and is connected to the substrate 10. The wiring 8c from the wireless charging unit 8B enters the third space SP3 through the opening Q3 in a part of the second heat insulating layer 22, and is connected to the secondary battery 8A. The wiring 7c from the light source unit 7 enters the third space SP3 through the opening Q4 in a part of the second heat insulating layer 22, and is connected to the substrate 10. The fourth thermal insulation layer 24 may also be omitted within the second thermal insulation layer 22. The openings Q1, Q2, Q3, and Q4 are each provided with a sealing material or the like, whereby heat insulation properties and the like can be improved. From the viewpoint of heat insulation, it is preferable that the number of openings such as the opening Q1 in the second heat insulating layer 22 be as small as possible. In this case, the plurality of openings may be combined into one opening.

In first space SP1, light source unit 7 and wireless charging unit 8B are more preferably provided on the upper surface of first thermal insulation layer 21, but may be provided on the upper surface of case bottom portion 2B when the heat resistance is high. In the region of the first space SP1, various members and heat insulating layers can be disposed as necessary. This is advantageous in terms of the height of the mouse function and the heat insulation.

In this example, the transfer unit 6 is a wiring that is routed back from the front side with respect to the center position of the electronic circuit component 5 and the like, and no notch or through hole is provided in the substrate 10. When the wiring is to be shortened, a region where the notch or the through hole is provided may be provided in the substrate 10, and a desired wiring path may be provided through the region.

Further, a heat insulating coating or a heat shielding coating may be applied to at least a part of the surface (upper surface, lower surface, etc.) of the substrate 10. For example, the lower surface 10u of the substrate 10 shown in fig. 7 may be heat-insulating coated. This reduces heat conduction into the substrate 10, and reduces the influence of heat conduction through the substrate 10 on the electronic circuit component 5 and other components. In addition, the amount of the heat insulating material to be installed can be reduced by the amount of the heat insulating coating of the substrate 10.

(6) Arrangement of electronic circuit component 5 to central portion in internal space of case 2

In embodiment 2, the electronic circuit component 5 is disposed in a position separated from any direction of the inner surface of the outer structural surface of the housing 2 in the internal space of the housing 2, for example, in a position near the central portion of the internal space. In embodiment 2 as well, the opening R1 for attaching the lens 4 is provided at a position near the left end of the housing bottom portion 2B (fig. 7 and the like) as in embodiment 1. That is, even in the mouse 1 according to embodiment 2, the arrangement positions of the electronic circuit components 5 and the substrate 10, which are objects to be protected by heat and water, are designed in consideration of the distance from the entire surface of the housing 2 during the sterilization process. In particular, the electronic circuit component 5 is disposed at a position near the center of the internal space of the casing 2 so as to be separated from the entire surface of the casing 2 as much as possible.

This can increase the degree of freedom in arranging the positions of the components such as the electronic circuit component 5 with respect to the position of the lens 4 (the position near the left end in fig. 7) of the opening R1 of the case bottom portion 2B. In particular, in the mouse according to embodiment 2, the components such as the electronic circuit component 5 can be arranged at appropriate positions in consideration of sterilization treatment, heat, water performance, and distance from the housing 2. This improves the heat resistance, water resistance, pressure resistance, and the like of the mouse 1, thereby realizing the performance of withstanding the sterilization treatment.

In other words, the distance K1 and the distance K3 are substantially equal to each other in the vertical direction (fig. 2) of the housing 2 of the mouse 1, the centers of the substrate 10 and the electronic circuit component 5 are separated by the distance K4A in the Y direction from the lower side surface of the housing upper portion 2A in the longitudinal direction of the housing 2, and the centers of the electronic circuit component 5 are separated by the distance K4B which is the distance between the outer surfaces of the side surfaces in the short direction of the housing upper portion 2A in the X direction orthogonal to the Y direction, whereby the substrate 10 and the electronic circuit component 5 are located at the substantially central portion of the internal space of the housing 2 of the mouse 1 in all directions of the vertical direction (Z direction) and the long direction (Y direction) of the housing 2 of the mouse 1 and in the short direction (X direction). In other words, the electronic circuit component 5 is disposed in a state of being spaced apart in all directions from the inner surface of the housing 2 of the mouse 1. The opening R1 and the lens 4 are disposed at a position far from the electronic circuit component 5, that is, at a position in the vicinity of the left end of the case bottom portion 2B, which is the front side of the mouse 1, and are spaced far from the electronic circuit component 5 disposed on the opposite side in the horizontal direction and the vertical direction. Therefore, even if the mouse 1 is exposed to high-temperature and high-pressure water vapor by autoclave treatment from all around, not only the opening R1 and the lens 4 but also the influence of high-temperature and high-pressure water vapor from any direction can be eliminated, thereby preventing damage and failure.

By positioning at least the electronic circuit component 5 and the substrate 10 at the center (including substantially the center or near the center) of the internal space of the housing 2 of the mouse 1, a sufficient distance can be secured between the electronic circuit component 5 and the substrate 10 and the inner surface of the structural surface of the housing 2, and even if subjected to sterilization treatment by high-temperature and high-pressure water vapor inside an autoclave device, for example, due to a thermal insulation effect by air and an insulating material described later, the effects of high-temperature, high-pressure, water vapor and the like from any direction can be eliminated, and damage and failure can be prevented.

[2-2: heat insulation structure

Fig. 8 shows a cross-sectional view of the mouse 1 corresponding to fig. 7. Fig. 8 is an explanatory diagram of a first configuration example of the multilayer heat insulation structure. Hereinafter, the respective layers will be described in order from the outside to the inside. Thermal insulation (thermal insulation) is a generic term for preventing heat transfer. The housing 2 and the respective heat insulating layers of the mouse 1 have resistance and strength against temperature and pressure changes during autoclave treatment. Fig. 8 shows a case where the transmission unit 6 is wired via the vicinity of one side surface in the X direction of the housing 2.

1. First, the case 2 has predetermined properties (first properties) including heat resistance, heat insulation, water resistance (including resistance to water vapor), water resistance (in other words, sealability), pressure resistance, durability (resistance to repeated use, temperature change, and the like), and the like. The case 2 is preferably made of a curved surface or the like, and is preferably contamination-proof and easily cleaned. In addition, the housing 2 has chemical resistance to water, disinfectant, and the like. The case 2 is made of a hard resin such as super engineering plastic. The super engineering plastic is an engineering plastic with strength, heat resistance, water resistance and the like. The housing 2 may be made of a material in which heat insulating particles are mixed. The housing 2 may be made of a reinforced resin material including a glass fiber, a carbon fiber, or the like. The casing 2 and the respective heat insulating layers are not limited to one layer, and may be formed of a plurality of layers.

2. The first thermal insulation layer 21 has properties (second properties) such as heat resistance, thermal insulation, and durability. The first thermal insulation layer may be provided to the entire casing 2 or may be provided to a part thereof. For example, the first thermal insulation layer 21 may be provided only on the bottom case 2B. The first thermal insulation layer 21 may also be a coating of the casing 2.

3. There is a space of air between the first heat insulating layer 21 and the second heat insulating layer 22 including the substrate 10, thereby having heat insulation. The space includes a first space part SP1 and a second space part SP 2. In this space, a heat insulating material, a heat absorbing material, a filler, and the like may be additionally disposed as described later.

4. The fourth heat insulating layer 24 (for example, the fourth heat insulating layer 24 of the transport unit 6) is disposed in a space such as the first space SP1 and the second space SP2 in the casing 2. The fourth thermal insulation layer 24 is more preferably not in contact with the first thermal insulation layer 21. The fourth thermal insulation layer 22 likewise has, for example, a second property. The fourth thermal insulation layer 22 may be further formed of multiple layers.

5. The second thermal insulation layer 22 likewise has, for example, second properties. The second thermal insulation layer 22 may also be further composed of multiple layers. The second heat-insulating layer 22 has a third space SP3 therein. The third space portion SP3 is a space of air, but may be a space filled with Ar gas, a space in a state close to vacuum, or a space filled with a heat insulating material or the like as a modification. In this case, the second heat insulating layer 22 has sealability. The substrate 10 and the second heat-insulating layer 22 are preferably configured to provide a space without contacting the case 2, which is more preferable from the viewpoint of thermal conductivity.

6. The third heat insulating layer 23 in the second heat insulating layer 22 has, for example, the same second property and also has insulation properties. Further, the respective surfaces of the substrate 10 and the mounted parts such as the electronic circuit part 5 may be subjected to a heat insulating coating having the same properties as those of the third heat insulating layer 23, for example.

In fig. 8, an example of the direction of heat applied from the outside of the mouse 1 during the sterilization process in the autoclave apparatus Y1 of fig. 25 is shown by an arrow. Here, the direction is shown focusing on the electronic circuit component 5. The direction of this heat ingress is omni-directional, but only eight directions are shown here. In the mouse 1 according to embodiment 2, the electronic circuit component 5 and the like are disposed at a position near the center in the housing 2 using the transmission unit 6. Therefore, when heat from the outside is conducted from each direction of the surface of the housing 2 to the electronic circuit component 5 during the sterilization process, the thermodynamic distance is large, and thus heat conduction is difficult. In addition, since the electronic circuit component 5 has a plurality of heat insulating layers in each direction, heat conduction to the electronic circuit component is difficult. In particular, since the opening R1 of the case bottom 2B is spaced apart from each other in the horizontal direction and the vertical direction, and the respective heat insulating layers are present, heat conduction from the opening R1 and the lens 4 can be prevented. The heat can be insulated by the respective heat insulating layers before reaching the electronic circuit part 5, and control of the temperature distribution in the internal space of the housing 2 is possible. Thereby, the electronic circuit component 5 and the like are protected from heat.

In embodiment 2, since a heat insulating material or the like is disposed between the housing 2 and the member to be protected, the position of the disposition may be selected so as to further shorten the distance between the housing 2 and the member to be protected in consideration of the performance of the heat insulating material or the like.

The heat insulating layers may be combined, not limited to the configuration example of fig. 9. For example, the first heat insulating layer 21, the second heat insulating layer 22, and the fifth heat insulating layer 25 may be provided. Further, the heat insulating layer may be provided not only in the surface of the casing 2 in all directions but also in a region where the heat insulating property is to be improved. For example, the respective heat insulating layers may be provided only in the region corresponding to the case bottom 2B.

[2-3: connection of lens to transfer part

Fig. 9 is a schematic diagram showing an example of a connection configuration between the lens 4 of the opening R1 of the housing bottom 2B and the optical fiber 6f as the transmission unit 6 in the mouse 1 according to embodiment 2. (A) A cross section is shown, and (B) a planar configuration is shown. A first thermal insulation layer 21 is disposed on the upper surface of the case bottom 2B. The lens 4, the optical fiber 6f, and the fourth heat-insulating layer 24 are disposed in the region of the width H1 of the opening R1. As shown in (B), the lens 4, the optical fiber 6f, and the like have, for example, an axisymmetric shape. The lens 4 preferably has properties such as no deformation, discoloration, or slight deformation or discoloration accompanying heat resistance, water resistance, pressure resistance, durability, and temperature change.

A lens 4 is fixed in the housing bottom 2B. The flange portion 4g of the lens 4 is a portion for fixing a position and sealing. The curved surface of the lens 4 (here, although convex, but not limited thereto) is configured not to protrude from the lower surface of the housing bottom 2B. The space between the curved surface of the lens 4 and the lower surface of the housing bottom portion 2B in the opening R1 has a shape with as few irregularities as possible for decontamination prevention and easy cleaning. Alternatively, a cover having light-transmitting property, heat resistance, water resistance, and the like is disposed in the space so as to be smooth with respect to the lower surface of the case bottom 2B. Alternatively, the lens 4 or a part of the cover may be extended downward with a curved shape with respect to the main surface of the case bottom B. One end of the optical fiber 6f is fixed to the center axis of the lens 4. The outer periphery of the optical fiber 6f is covered with a fourth heat insulating layer 24. In manufacturing, the case bottom 2B is formed by injection molding, for example, whereby the components can be fixed to each other. An adhesive, a heat insulating material, a sealing material such as a resin gasket (O-ring), or the like may be provided in the vicinity of the flange portion 4 g. Such connection can also be reinforced by imparting adhesiveness to the first heat insulating layer 21, the fourth heat insulating layer 24, the fifth heat insulating layer 25, and the like. The adhesive material and the sealing material are desired to have heat resistance. In this example, the optical fiber 6f and a part of the fourth heat insulating layer 24 are embedded in the housing bottom 2B, but the present invention is not limited thereto. As another configuration example, when the housing 2 is composed of an outer shell and an inner shell, the lens 4 may be fixed between the outer shell and the inner shell. In the case where the light source portion wiring 7d from the light source portion 7 exists, for example, one end of the light source portion wiring 7d (schematically shown by a broken line) using an optical fiber may be optically connected to the lens 4 in the housing bottom portion 2B.

[2-4: effects and the like

(a) As described above, according to the mouse of embodiment 2, by providing the multi-layer heat insulating structure, the heat insulating property, the water resistance, and the like can be further improved as compared with embodiment 1. In addition, this configuration can also withstand the autoclave sterilization process of class B (fig. 25). In the medical field, the sterilized mouse can be used for surgery or the like. In the case where a member having heat resistance or the like is used for all the components inside the case 2, the heat insulating structure inside the case 2 may not be necessary or omitted, and the configuration of embodiment 1 may be adopted.

(b) In the mouse according to embodiment 2, by positioning at least the electronic circuit component 5 and the substrate 10 at the central portion (including substantially the central portion or the vicinity of the central portion) of the internal space of the housing 2 of the mouse 1, a sufficient distance can be secured between the electronic circuit component 5 and the substrate 10 and the inner surface of the structural surface of the housing 2, and due to a thermal insulation effect by air or an insulating material, for example, even when subjected to a sterilization treatment by high-temperature and high-pressure water vapor inside an autoclave device, for example, the influence of high-temperature, high-pressure, water vapor, and the like from any direction can be eliminated, and occurrence of damage and failure can be prevented.

[2-5: modification 2

Fig. 10 shows a configuration of a mouse 1 according to modification 2 of the mouse according to embodiment 2. (A) Showing a longitudinal section, and (B) showing a planar structure. Modification 2 is basically and commonly based on the configuration of modification 1 of fig. 6, and has a heat insulating structure added thereto. The casing 2 has a first thermal insulation layer 21 on its inner surface. The rod 3d of the push button 3 and the support portion 2C of the case bottom portion 2B penetrate through the first and second heat insulating layers 21 and 22. Further, the second heat insulating layer 22 may be interposed between the rod 3d and the switch 3 e. The substrate 10 having the plurality of electronic circuit components 5(5a, 5b), the secondary battery 8A, and the switch 3e is housed in the second heat insulating layer 22. The electronic circuit components 5a, 5b and the secondary battery 8A are covered with a third heat insulating layer 23, respectively. Even in the case where the third heat insulating layer 23 is disposed below the substrate 10 as in the present embodiment, an important function of supporting and/or fixing at least a part of the substrate 10 can be achieved.

As another modification, the mouse 1 having a wired communication function may be provided, and an opening 1002 for the wired communication cable 1001 may be provided in a part of the housing 2, for example, in a position on the front side of the housing upper portion 2A. The wired communication cable 1001 and the opening 1002 have heat insulation properties, sealing properties, and the like. In addition, the power supply unit 8 may be provided with a terminal or a power supply cable so as to protrude outside the housing 2. In this case, the terminal or the power cable and the opening portion therefor have heat insulation properties, sealing properties, and the like in the same manner. In this case, no battery is required within the housing 2. Further, it is preferable that a metal portion of a component such as a connector, not shown, related to the wired communication cable 1001, the power cable, or the like has rust prevention properties.

As another modification, a region such as a notch or a through hole may be provided in a part of the surface of the substrate 10 and a part of the corresponding second heat-insulating layer 22, and the wiring of the transfer unit 6 may be routed through the region.

[2-6: modification 3

Fig. 11 shows a vertical cross section of a mouse 1 according to modification 3 of the mouse according to embodiment 2. In modification 3, the light source unit 7 is provided on the substrate 10 and surrounded by the second heat insulating layer 22. On the upper surface side of the substrate 1, for example, an LED element is mounted as the light source unit 7 at a position closer to the front. The light source section 7 is controlled by the electronic circuit component 5 via the circuit of the substrate 10. The light source wiring 7d from the light source unit 7 extends toward the first space SP1 through, for example, a partial opening of the second heat insulating layer 22, and is connected to the lens 4. The light source section wiring 7d is covered with the fourth heat insulating layer 24 using, for example, an optical fiber. The light source portion wiring 7d and the optical fiber 6f of the transmission portion 6 may be collected by the fourth heat insulating layer 24 and the fifth heat insulating layer 25.

In modification 3, the electronic circuit component 5, the secondary battery 8A, and the wireless charging unit 8B on the case bottom 2B are substantially entirely surrounded by the third heat insulating layer 23 in the third space SP3 in the second heat insulating layer 22. In modification 3, a separate component such as the secondary battery 8A is mounted on the substrate 10 via a part of the third heat insulating layer 23, and a part of the third heat insulating layer 23 is also disposed between the lower surface of the separate component such as the secondary battery 8A and the upper surface of the substrate 10. The wireless charging section 8B is disposed on the first heat insulating layer 21 through a part of the third heat insulating layer 23. In the case where the third heat insulating layer 23 is disposed below the substrate 10 as in the present embodiment, an important function of supporting and/or fixing the substrate 10 at least in part can be achieved.

[2-7: modification 4

Fig. 12 shows a configuration of a mouse 1 according to modification 4 of the mouse according to embodiment 2. This modification 4 shows an example of a configuration in which a light introducing portion such as a slope portion is provided in the housing 2 when the light source portion 7 (or an illumination device such as an LED) is not provided. (A) Showing a longitudinal section and (B) showing a transverse section. The housing 2 is provided with a slope portion 1202 as a light introducing portion in a partial region 1201 as viewed from the side. The region 1201 is a region which is close to the case bottom portion 2B in the Z direction and on the left and right sides in the X direction except for the opening portion R1 in the vicinity of the left end of the case bottom portion 2B in fig. 12 (front side in the Y direction), and has a curved surface which is easy to grip with a hand, for example. Due to the shape of the housing 2, ambient illumination light easily enters the lens 4 of the opening R1 through the region 1201 between the housing and the installation surface SF. Thus, even when the light source unit 7 is not provided, the illumination light in the room can be applied in many cases. This eliminates heat generation by the light source unit 7 in the housing 2, thereby increasing the usable time of the mouse.

In fig. 12, the conveying unit 6 and the like are not shown. In this configuration, the wiring of the transmission unit 6 can be, for example, a wiring in the front-rear direction described later. In this structure, the upper substrate 10 and the second heat insulating layer 22 of the slope portion 1202 may be placed or fixed by using the slope portion 1202 protruding from the case bottom 2B. Even in the case where the third heat insulating layer 23 is disposed below the substrate 10 as in the present embodiment, an important function of supporting and/or fixing the substrate 10 at least in part can be achieved.

[2-8: wiring example 2

Fig. 13 shows another wiring example of the transmission unit 6 as a modification of the mouse according to embodiment 2. Fig. 13 shows a case where the front-side wiring is provided as wiring example 2. (A) A longitudinal section is shown, and (B) a planar configuration is shown. The transmission unit 6 uses, for example, an optical fiber 6 f. The optical fiber 6f is covered by a fourth insulating layer 24. The wiring path of the transfer unit 6 is as follows. First, one end of the optical fiber 6f of the transmitting portion 6 is connected to the position of the lens 4 of the opening R1 near the left end (front side in the Y direction) of fig. 13 of the housing bottom portion 2B. From this position, the optical fiber 6f extends upward in the Z direction in the first space portion SP1 to reach a position above the substrate 10. From this position, the optical fiber 6f extends rearward in the Y direction to the vicinity of the center on the upper surface side of the second heat insulating layer 22 in the second space portion SP 2. Then, the other end of the optical fiber 6f enters the third space SP3 through the opening Q1 of the second heat-insulating layer 22, and is connected to the upper surface of the image sensor 15 of the electronic circuit component 5.

In first space SP1, wireless charging unit 8B is disposed, for example, in a region located further back. As a modification, a region such as a notch or a through hole may be provided in a part of the substrate 10 and the second heat insulating layer 22, and the wiring of the transmission unit 6 may pass through the region.

[2-9: wiring example 3

Fig. 14 shows a wiring example 3 of the transmission unit 6 as a modification of the mouse of embodiment 2. In this embodiment, unlike the other embodiments, the opening R1 and the lens 4 are not provided near the left end of the case bottom 2B in fig. 14, but are provided near the right end (rear side in the Y direction) which is the opposite side in the longitudinal direction. Thus, wiring example 3 is the case of the rear side wiring. (A) A longitudinal section is shown, and (B) a planar configuration is shown. The wiring path of the transfer unit 6 is as follows. First, the optical fiber 6f of the transmission unit 6 extends upward in the Z direction from the position of the lens 4 of the opening R1 near the right end of fig. 14 of the housing bottom portion 2B in the first space portion SP1 to reach a position above the substrate 10. From this position, the optical fiber 6f extends forward in the Y direction to the vicinity of the center on the upper surface side of the second heat insulating layer 22 in the second space portion SP 2. Then, the other end of the optical fiber 6f enters the third space SP3 through the opening Q1 of the second heat-insulating layer 22, and is connected to the upper surface of the image sensor 15 of the electronic circuit component 5. The light source unit 7 is disposed above the substrate 10, and is wired (omitted) from here to the lens 4.

[2-10: example of positional relationship (1)

Fig. 15 shows a modification of the mouse according to embodiment 2, which is an example of a configuration such as a positional relationship between the lens 4 and the electronic circuit component 5 and wiring. (A) A longitudinal section is shown, and (B) a planar configuration is shown. In the configuration example of fig. 15, the lens 4 having the opening R1 is disposed at a position near the center of the housing 2 in a plan view on a horizontal plane, and the electronic circuit component 5 and the image sensor 15 are disposed at positions different in the horizontal direction, the planar direction, and the vertical direction, that is, positions on the front side. The positional relationship of the two is shown by a dashed arrow. In this configuration, the electronic circuit component 5 and the like are disposed at positions separated in distance from the lens 4 of the opening R1. In the configuration example of fig. 15, the use of the transmission unit 6 increases the degree of freedom in the arrangement position of the electronic circuit components 5 and the like. For example, the electronic circuit component 5 and the like can be selected and arranged at a position where performance with respect to heat and water is easily ensured. The electronic circuit component 5 and the like can be arranged at such a position for any reason.

In this configuration example, the wiring of the transmission unit 6 is provided as a front side wiring, particularly a wiring via the opening Q1 on the side surface of the second heat insulating layer 22. The optical fiber 6f of the transmission unit 6 extends forward from the position of the lens 4 in the first space SP1, extends upward from the front space, and enters the third space SP3 through the opening Q1 on the front side surface of the second heat insulating layer 22. Then, the other end of the optical fiber 6f is wired inside the second heat insulating layer 22, and connected to the image sensor 15 of the electronic circuit component 5 on the front side on the substrate 10. The wiring is not limited to this example, and may be provided as a wiring passing through a region vacant in the housing 2. Further, the fourth heat insulating layer 24 may be omitted in the second heat insulating layer 22. The secondary battery 8A may be disposed near the center of the substrate 10, and other components may be mounted.

In the modification of fig. 15, the opening R1 is arranged to separate the lens 4 from the electronic circuit component 5 and the image sensor 15 at different positions in the horizontal direction, and therefore, even if heat or water enters the mouse 1 through the opening R1 and the lens 4 due to autoclave treatment or the like, the heat or water can be prevented from reaching the electronic circuit component 5 and the image sensor 15.

[2-11: example of positional relationship (2)

Fig. 16 shows another configuration example of the positional relationship between the lens 4 and the electronic circuit component 5, the wiring, and the like, as a modification of the mouse of embodiment 2. (A) A longitudinal section is shown, and (B) a planar configuration is shown. In this configuration example, the electronic circuit component 5 and the like are disposed at a position near the center of the housing 2 in a plan view of the horizontal plane, and the opening R1 and the lens 4 are disposed at positions different in the horizontal direction, that is, at a position on the front side of the housing bottom portion 2B. Even with this configuration, the electronic circuit component 5 is disposed at a position separated by a distance in the horizontal direction and the vertical direction with respect to the opening R1, the lens 4, and the like.

This modification is somewhat similar to embodiment 1, but is mainly different from embodiment 1 in that the electronic circuit component 5 and the like are disposed at positions near the center of the housing 2, and the opening R1 and the lens 4 are disposed at different positions spaced apart from each other in the horizontal direction, that is, at an intermediate position on the left side (fig. 16) of the housing bottom portion 2B.

The following configuration is provided as an example of the wiring of the transmission unit 6. The optical fiber 6f of the transmission section 6 extends upward in the first space SP1 from the position of the lens 4 in the opening R1, and enters the third space SP3 through the opening Q1 on the lower surface side of the second heat insulating layer 22. The optical fiber 6f passes through a region 1601 such as a notch or a through hole provided in the substrate 10, and protrudes toward the upper surface side of the substrate 10. The other end of the optical fiber 6f extends backward in the Y direction to the vicinity of the center on the upper surface side of the substrate 10, and is connected to the image sensor 15 of the electronic circuit component 5. Further, even in the substrate of the conventional mouse, there are cases where regions such as the notch and the through hole are provided. Such a region can be used for wiring of the transfer portion 6. By disposing the lens 4 of the opening R1 at a position horizontally spaced apart from the center of the case bottom 2B, heat and moisture entering the mouse 1 through the opening R1 and the lens 4 can be prevented from reaching the electronic circuit component 5.

In (B), other wiring examples are shown schematically by arrows. In the case where the substrate 10 has no notch in the region 1601, various wirings such as wiring examples EX1, EX2, EX3, and EX4 may be used. Wiring example EX1 is an example of the wiring example extending from the position of lens 4 once from the front space and then passing through second space SP2 and the like. Wiring example EX2 is an example of a position diagonally forward to the left in the side surface of case 2. Wiring example EX3 is an example of electronic circuit component 5 extending leftward of housing 2 from the position of lens 4, rearward on the left side, upward on substrate 10, and to the center. The wiring example E43 is an example of the electronic circuit component 5 that extends obliquely rearward to the left from the position of the lens 4, extends upward on the left side of the housing 2, extends upward above the substrate 10, and extends obliquely to the center.

[2-12: wiring example 4

Fig. 17 shows a wiring example 4 of the transmission unit 6 as a modification of the mouse of embodiment 2. The wiring example 4 shows a case where the wiring is provided so as to penetrate linearly upward. (A) A longitudinal section is shown, and (B) a planar configuration is shown. The wiring path of the transfer unit 6 is as follows. The transmitting portion 6 extends upward in the Z direction in the first space portion SP1 from the position of the lens 4 in the opening R1 near the center of the housing bottom portion 2B to reach the opening Q1 of the second heat insulating layer 22. In this example, the transfer part 6 is covered with a fifth heat insulating layer 25. In other words, the transfer portion 6 penetrates the fifth heat insulating layer 25. The conveying unit 6 enters the third space SP3 through the opening Q1, and penetrates upward through the region 1701 of the through hole of the substrate 10. The upper electronic circuit component 5 of the through hole portion is mounted on the upper surface of the substrate 10, and the image sensor 15 is mounted on the lower surface side of the electronic circuit component 5, as in the third example of fig. 5.

In this modification, the conveyor 6 linearly extends upward only at the same position, and the wiring path length is shorter than that in the above-described embodiment. The transmission unit 6 uses, for example, an optical fiber 6f arranged linearly. The optical fiber 6f may be an inflexible optical fiber, or may be covered with a rigid cylindrical member or a fourth heat insulating layer 24. The transmission unit 6 is not limited to the linear optical fiber 6f, and may be formed of another optical member. The conveying section 6 may be formed of a cylindrical light guide (e.g., a lens barrel described later). The conveying unit 6 may be formed of a flexible member or a rigid member. The image light incident from the lens 4 is reflected by the cylindrical light guide body as necessary, travels upward, and enters the image sensor 15. A fourth heat insulating layer 24 may be provided on the light guide. The lens 4 of the housing bottom portion 2B and the light guide may be integrally formed (the conveying portion 6 or the optical member).

In this modification, in the first space portion SP1, the fifth heat insulating layer 25 is provided in a partial region between the first heat insulating layer 21 and the second heat insulating layer 22. The fifth heat insulating layer 25 positions and fixes the second heat insulating layer 22 surrounding the substrate 10. In a plan view, the fifth thermal insulation layer 25 is provided to have a larger area than the area 1701 of the through hole. This further improves the heat insulation between the opening R1 and the electronic circuit component 5.

Even in this modification, the distance between the lens 4 and the electronic circuit component 5 is sufficiently secured, and the first heat insulating layer 21, the fifth heat insulating layer 25, and the second heat insulating layer 22 are provided therebetween, so that the effect of improving the heat insulating property for protecting the electronic circuit component 5 and the like is obtained. Even when the substrate 10 has a through hole or the like, the fifth heat insulating layer 25 enhances heat insulation. Such an approach is possible in the case where it is desired to shorten the wiring path length of the transfer section 6.

The fifth heat insulating layer 25 is a material that is deformed, for example, by flexibility during manufacturing, and the second heat insulating layer 22 including the substrate 10 is positioned and fixed by being placed above the fifth heat insulating layer 25 and pressed. The fifth heat insulating layer 25 is hardened by temperature control or the like, whereby the substrate 10 and the second heat insulating layer 22 and the like are fixed and hardened. In addition, when the fifth heat insulating layer 25 is disposed below the substrate 10 as in the present embodiment, an important function of supporting and fixing the substrate 10 can be achieved.

[2-13: wiring example 5

Fig. 18 shows a wiring example 5 of the transmission unit 6 as a modification of the mouse of embodiment 2. The wiring example 5 shows another example of the through-top linear wiring. In this modification, the substrate 10 is disposed in the vertically opposite direction to the above-described embodiment. The wiring path of the transfer unit 6 is as follows. The optical fiber 6f as the transmission section 6 first extends upward in the Z direction from the position of the lens 4 in the opening R1 near the center of the housing bottom section 2B in the first space section SP1, and enters the third space section SP3 through the opening Q1 of the second heat insulating layer 22. The optical fiber 6f is covered by, for example, a fifth insulating layer 25. In third space SP3, optical fiber 6f extends upward in a region on the upper surface side (lower surface side as a whole) of substrate 10, and is connected to the upper surface (lower surface as a whole) of image sensor 15 (similar to the second example of fig. 5) on upper surface 5U of electronic circuit component 5.

The electronic circuit component 5 of the substrate 10 is disposed on the lower surface of the substrate 10 in a position near the center, for example, within the housing 2. The distance K1B between the lower surface of the case bottom 2B and the upper surface of the electronic circuit component 5 may be selected in consideration of performance with respect to heat and the like. In this modification, since the substrate 10 is disposed in the opposite direction, the electronic circuit component 5 and the transmission unit 6 can be connected without providing a through hole or the like in the substrate 10. As in this modification, the wiring of the transfer unit 6 and the like may be positioned below the substrate 10 in the second heat insulating layer 22.

In this modification, the light source unit 7 is attached to, for example, the front side of the upper surface side (lower surface side in the entire) of the substrate 10, and is housed and protected in the second heat insulating layer 22. The light source section wiring 7d from the light source section 7 extends to a position near the center in, for example, the third space SP3, extends outward through the opening Q1, extends downward, and is connected to the lens 4. The light source portion wiring 7d may be an optical fiber. Two kinds of wirings (the transmission unit 6 and the light source unit wiring 7d) are collected in the opening Q1, thereby improving heat insulation performance and the like. In the case of collecting a plurality of wirings, a fourth heat insulating layer 24, a fifth heat insulating layer 25, a binder, or the like may be used. In addition, when the fifth insulating layer 25 is disposed below the substrate 10 as in the present embodiment, an important function of supporting and fixing the substrate 10 can be achieved.

< embodiment 3>

A mouse according to embodiment 3 of the present invention will be described with reference to fig. 19. The mouse of embodiment 3 shows an example of another heat insulating structure.

[3-1: heat insulation structure

Fig. 19 shows a cross section of a multilayer heat insulating structure in a mouse according to embodiment 3. First, the case 2 may be formed of a multi-layer case (in other words, a case portion) having two or more layers. In other words, a sub-housing portion (a case, a cover, or the like) may be provided outside or inside the main housing 2. The outer case may be an outer cover and the inner case may be a main body, or the outer case may be a main body and the inner case may be an inner cover. In the configuration example of fig. 19, the housing 2 has a double structure of an outer case 2S (outer housing portion) and an inner case 2T (inner housing portion). In detail, the outer case 2S has an outer case upper part 2a1 and an outer case bottom part 2B1, and the inner case 2T has an inner case upper part 2a2 and an inner case bottom part 2B 2. The upper housing part 2A has an upper outer housing part 2A1 and an upper inner housing part 2A2, and the lower housing part 2B has an outer housing part 2B1 and an inner housing part 2B 2. The outer shell and the inner shell can be arranged into a whole or a part. For example, only the case bottom 2B may be formed of a double shell. Each casing is made of a member having heat resistance, heat insulation, water resistance, pressure resistance, and the like. The properties of the individual housing portions may also be different. At the position SZ1 where the case 2 is separated, a sealing material or the like is arranged in the same manner as described above.

In the configuration example of fig. 19, the first thermal insulation layer 21 is sandwiched and held between the outer shell 2S and the inner shell 2T of the case 2 (the region between the inner surface sf2 of the outer shell 2S and the outer surface sf3 of the inner shell 2T). This stably holds the first thermal insulation layer 21 against the surface of the case 2, and thus, peeling or the like is less likely to occur.

Further, other members such as a member (including paint), a bonding material, and a sealing material for improving heat insulation or the like may be provided between the respective housing portions and on the outer surface and the inner surface of the respective housing portions. Bonding materials such as heat-resistant adhesive materials may be provided on the inner surface sf2 of the outer case 2S and the outer surface sf3 of the inner case 2T. The outer casing 2S, the first thermal insulation layer 21, and the inner casing 2T are closely bonded to each other, but the present invention is not limited thereto, and an air layer, a vacuum layer, an Ar gas layer, or the like may be provided between the respective layers. The outer casing 2S, the first thermal insulation layer 21, the inner casing 2T, and the like may be formed by injection molding or the like at the time of manufacture.

Further, a painting layer 26 for improving thermal insulation, tone and the like may be provided on the outer surface sf1 of the casing 2S (the casing upper part 2a1 and the casing bottom part 2B 1). In other words, the housing 2S may be made of resin or the like including the coating layer 26. A cover having heat insulation and sealing properties described later may be provided on the outer surface sf1 of the housing 2S. Further, the heat absorbing material may be mixed into the outer shell 2S and the inner shell 2T of the case 2. This allows the case 2 to absorb heat from the outside in an appropriate temperature range, thereby suppressing heat conduction into the case 2.

In addition, a heat shielding structure may be provided in the casing 2. For example, an infrared absorbing layer and an infrared reflecting layer on the inner side than the infrared absorbing layer are provided on the outer surface sf1 or the inner surface sf2 of the outer case 2S, and the first thermal insulation layer 21 is provided on the outer surface sf3 or the inner surface sf4 of the inner case 2T. Thus, the case 2 has a heat shielding property against heat (including infrared rays) from the outside during the sterilization process. The material constituting the housing 2 may be mixed with the material constituting the infrared absorbing layer and the infrared reflecting layer. In this case, since the temperature is constant during sterilization in the autoclave (the sterilization process YS13 in fig. 25), the heat absorbed by the infrared absorbing layer is radiated to the outside of the mouse.

The inner space (first space SP1 and first space SP2) of the case 2, the opening R1, and the like are sealed by the outer case 2S, the inner case 2T, the first thermal insulation layer 21, the sealing material, and the like. This makes it difficult for heat generated during the autoclave treatment to propagate through the casing 2 and for water vapor to enter the casing 2. The housing 2S may be formed of a cover body made of, for example, silicone rubber. The inner casing 2T may also be made of, for example, super engineering plastic.

In this configuration example, the second heat-insulating layer 22 is formed of a plurality of layers, for example, three layers of a layer 22a, a layer 22b, and a layer 22c in this order from the outside. The other heat insulating layer may be formed of a plurality of layers.

< embodiment 4>

A mouse according to embodiment 4 of the present invention will be described with reference to fig. 20. The mouse according to embodiment 4 is an example in which the heat insulating structure is another structure.

[4-1: heat insulation structure

Fig. 20 (a) shows a cross section of a multilayer heat insulating structure in a mouse according to embodiment 4. In the mouse 1, the case 2 is composed of the outer case 2S and the inner case 2T, the first heat insulating layer 21 is provided between the outer case 2S and the inner case 2T, and the substrate 10 is surrounded by the second heat insulating layer 22 in the inner space inside the inner case 2T. In embodiment 4, the predetermined empty region is filled with the filler 27 in the internal space of the housing 2. The filler 27 may be a material having heat insulating properties and heat resistance, and may be a heat insulating layer added thereto. The filling material 27 is made of, for example, an electrically insulating resin, and is filled in a predetermined region during production and then cured by temperature control. The heat resistance of the mouse is further improved by the filler 27. Fig. 20 a shows a case where the filler 27 is disposed in a part of the internal space of the housing 2 as an example of the disposition of the filler 27 (corresponding filling region). For example, the filler 27b may be disposed in the entire first space SP1, or the filler 27b may be disposed in an area where no member is present. Such a filling material 27 may also be provided as the aforementioned fifth insulating layer 25. The filler 27a or the filler 27b further improves heat resistance against heat from the lower side of the substrate 10. The filler 27a or 27b may position and fix the second heat-insulating layer 22 surrounding the substrate 10 on the upper side, or may fix the wiring of the transfer unit 6.

Further, the filler 27c may be disposed in the upper second space SP 2. The filler 27c further improves heat resistance against heat from the upper side of the substrate 10. Further, the filler 27d may be disposed in the third space SP3 in the second heat-insulating layer 22. The heat resistance and the like of the substrate 10 are further improved by the filler 27 d. The filler 27c may be formed along the inner surface of the case 2. Further, when the filler 27a and the filler 27c are disposed below the substrate 10 as in the present embodiment, an important function of supporting and/or fixing the substrate 10 can be achieved.

Fig. 20 (B) shows a case where the filler 27 is disposed substantially entirely in the internal space of the housing 2 as another example of the disposition of the filler 27. For example, the filler 27 is disposed in a substantially entire region between the inner case 2T (or the first heat insulating layer 21) and the second heat insulating layer 22. For the filling material 27, a foaming activator (foaming heat insulating material) such as foamed polyurethane may be used. In this case, the foaming agent is injected into the case 2 after the parts other than the filler 27 are formed at the time of manufacturing. The foaming agent injected into the housing 2 foams and fills substantially the entire region of the internal space (filling region) as shown in (B), for example. The activation method is not limited to temperature change, and may be chemical change due to retardation, light, electromagnetic wave, acoustic wave, vibration, or the like. Further, a part of the case 2 (for example, the opening R1) may be used as an injection port of the foaming activator, and the internal pressure may be adjusted by finally closing the opening. The substrate 10 and the second heat-insulating layer 22 may be lifted upward by injecting and filling the filling material 27 from an injection port of the case bottom 2B, thereby forming the arrangement as shown in the drawing.

[4-2: modification example

As a modification of embodiment 4 shown in fig. 20, the following configuration may be adopted, which is different from the above-described embodiments in the thermodynamic viewpoint. In this modification, a heat absorbing material may be disposed instead of the first heat insulating layer 21. The heat absorbing material is made of a heat absorbing material having a large heat storage capacity or a large heat capacity. The heat absorbing material absorbs heat from the outside of the case 2 in a predetermined temperature range and remains there. This reduces or suppresses heat conduction from the electronic circuit component 5 and the like to the inside from this portion. Likewise, the inner casing 2T may be made of a heat absorbing material. Alternatively, the fifth insulating layer 25 or the filler 27 may be made of a heat absorbing material. It is also possible that a portion of the second thermal insulation layer 22 is made of a heat absorbing material. The respective heat insulating layer, filling material, or heat absorbing material may have adhesion to other members.

< embodiment 5>

A mouse according to embodiment 5 of the present invention will be described with reference to fig. 21. The mouse of embodiment 5 shows a modification of the transmission unit 6.

[5-1: conveying part

Fig. 21 shows an example of the configuration of the transmission unit 6 in the mouse according to embodiment 5. (A) The first example is shown, and (B) the second example is shown. In (a), the transmission unit 6 is composed of the optical fiber 6f and the optical coupler 60. The optical fiber 6f may also be covered by a fourth insulating layer 24. The optical fiber 6f extends, for example, upward from the position of the lens 4 in the opening R1 of the case bottom 2B, and is connected to the image sensor 15 of the electronic circuit component 5 of the substrate 10. The optical coupler 60 is disposed at a position midway in the optical fiber 6 f. In other words, the optical fiber 6f of the transmission unit 6 may be formed of a plurality of optical fibers, and the optical coupler 60 may form one transmission path by bundling the plurality of optical fibers. In this example, the optical coupler 60 physically and optically couples the end of the lower optical fiber and the end of the upper optical fiber. The optical coupler 60 relays direct transmission of image light by the optical fiber. The optical coupler 60 may also include an optical fiber bonded to the fourth layer of insulation 24. The optical coupler 60 may also serve as a binder to bind a plurality of optical fibers.

The optical coupler 60 may have heat insulation properties. The light-transmitting heat insulator 61 may be provided in the optical coupler 60. The translucent heat insulating portion 61 transmits image light, has heat insulating properties, and separates heat on the conveyance path. The light-transmitting heat insulator 61 may be a light-transmitting heat insulator, or may be an air layer, a vacuum layer, or a layer made of Ar gas. This improves the heat insulation property in the transmission unit 6, and makes it more difficult to conduct heat to the electronic circuit component 5 and the like.

In the example of (B), the transmission unit 6 is provided as a front wiring from the position of the lens 4 and the opening R1 provided on the front side of the mouse 1, that is, in the vicinity of the left end of the housing bottom portion 2B. The optical coupler 60 is similarly disposed in the middle of the transmission path of the optical fiber 6f constituting the transmission unit 6. The optical coupler 60 may be fixed to a predetermined position such as a side surface of the second heat-insulating layer 22. This allows the wiring of the transmission unit 6 to be appropriately positioned, and can be located at a more thermally favorable position. The wiring of the transfer unit 6 may be fixed by another member. In this configuration example, the optical coupler 60 is disposed in the opening Q21 on the side surface of the second heat insulating layer 22 and also functions as a seal. The optical fiber 6f of the portion further to the rear than the optical coupler 60 is routed in the second heat insulating layer 22.

< embodiment 6>

A mouse according to embodiment 6 of the present invention will be described with reference to fig. 22. The mouse of embodiment 6 shows an example of the configuration of the optical element with respect to the case bottom 2B.

[6-1: optical element

Fig. 22 (a) is a schematic diagram showing a vertical cross section of an example of the configuration of the lens 4 in the opening R1 of the housing bottom portion 2B in the mouse according to embodiment 6. In this configuration example, a sealing heat insulating structure is added to the lens 4 as the optical element of the case bottom portion 2B. In this configuration example, the optical element as the lens 4 is configured as a lens structure 40 having a barrel 41. The lens structure 40 includes one or more lenses. In other words, the lens structure 40 is an image light incident portion.

The case bottom 2B is constituted by, for example, an outer case bottom 2B1 and an inner case bottom 2B 2. In a part of the inner case bottom portion 2B2, the lens barrel 41 of the lens assembly 40 is formed to protrude inward in a convex shape. In this example, the lens barrel 41 is fixed by the screw structure portion 42 to a fixing portion (screw hole) 43 projecting upward from the inner case bottom portion 2B 2. A screw structure portion 42 is formed on the inner peripheral surface of the fixing portion 43 and the outer peripheral surface of the corresponding lens barrel 41. On the upper side of the inner casing bottom portion 2B2, a first thermal insulation layer 21 is formed so as to cover the barrel 41 and the fixing portion 43. The lens structure 40 has a substantially axisymmetric shape. The axes are shown in single-dotted chain lines. The space 2300 near the axis of the lens barrel 41 is a region corresponding to the width H1 of the opening R1, and is divided by the lenses 4A and 4B, which are a plurality of lenses. In this example, the case of two lenses is shown, but the number and shape of the lenses are not limited. The lens 4A is fixed to the inner surface of the lens barrel 41 at a lower position via a member 41a having a screw structure portion and a sealing member, and the lens 4B is fixed to the inner surface of the lens barrel 41 at an upper position via a member 41B having a screw structure portion and a sealing member. The lens 4A is a lens having a convex curved surface on the lower side, and the lens 4B is a lens having a convex curved surface on the upper side. The space 2300 of the lens barrel 41 is partitioned by the lenses 4A and 4B to form a translucent heat insulating portion 2302. The light-transmissive heat-insulating portion 2302 is a layer made of an air layer, a vacuum layer, Ar gas, or a light-transmissive heat-insulating material. One end of a transmission unit 6, not shown, is connected to an upper portion of the lens barrel 41.

The heat shielding filter 2301 is provided in a region corresponding to the opening R1 of the case bottom 2B1 so as to be smooth with respect to the lower surface of the case bottom 2B 1. The heat shielding filter 2301 is a filter or a cover that has image light transmittance, shields heat from the outside, and prevents the entry of water (water vapor). The heat shielding filter 2301 may be provided in the inner case bottom 2B2 and the lens barrel 41.

In manufacturing, the lenses 4A and 4B are fixed to the lens barrel 41, and the lens barrel 41 is fixed to the fixing portion 43 with the sealing member 2303 interposed therebetween. The screw structure portion 42 has sealing properties and heat insulating properties. For example, the sealing material 2303 is provided in a region of a lower part of the barrel 41 in contact with the fixed portion 43. A heat insulating material may be provided in addition to the sealing material 2303.

With the configuration of embodiment 6 including the lens barrel 41 and the like, the water resistance near the opening R1 can be improved, and the positioning of the lens and the connection between the lens and the transmission unit 6 can be facilitated. The first space portion SP1 (distance K2 in fig. 2) is also secured by the conveying portion 6, and therefore the lens barrel 41 and the like having a certain height can also be provided. As another configuration example, when a cover having image light transparency is used as the case bottom 2B1, the opening R1 may be covered by the cover. The light source wiring 7d from the light source 7 may be connected to the lens structure 40. For example, the light source portion wiring 7d is optically connected to the space 2300 via the fixing portion 43 wiring.

[6-2: modification example

Fig. 22 (B) shows a configuration of a mouse in a modification (modification 5) of embodiment 6. In this modification, the lens structure 40 is extended upward in the Z direction, in other words, the length of the lens barrel 41 in the Z direction is increased so as to reach the vicinity of the image sensor 15 of the electronic circuit component 5 of the substrate 10. Thereby, the linear barrel type lens structure 40 is set as the transfer unit 6. The transmission unit 6 has both a function as an image light incident unit and a function as a transmission path to the image sensor 15. In the lens barrel 41 of the conveying section 6, the end of the upper side in the Z direction extends to the surface of the image sensor 15 of the electronic circuit part 5 such as the substrate 10, and the optical axis of the lens barrel 41 and the optical axis of the image sensor 15 are aligned. The upper end of the lens barrel 41 may be fixed to the image sensor 15, the electronic circuit component 5, the substrate 10, the second heat-insulating layer 22, or the like. The space 2300 in the barrel 41 may be entirely or partially filled with a translucent insulating material.

< embodiment 7>

A mouse according to embodiment 7 of the present invention will be described with reference to fig. 23. The mouse of embodiment 7 shows a configuration example in which the image sensor 15 and the like are disposed on the housing bottom portion 2B.

[7-1: image sensor of bottom of housing

Fig. 23 (a) shows a vertical cross section of a mouse 1 as a mouse according to embodiment 7. In the mouse 1 according to embodiment 7, the image sensor 15h and the light source unit 7h are arranged in close proximity to each other and in parallel at a position near the left end (position on the front side in the Y direction) spaced from the housing bottom 2B to the left side in fig. 23. The image sensor 15h is an imaging element (in other words, an image detection unit) which is disposed on the housing bottom portion 2B and converts image light from the outside (installation surface SF) into an image signal by being incident thereon. The light source section 7h is a light emitting element disposed on the case bottom section 2B and emitting illumination light to the outside (installation surface SF). The outer surfaces of the image sensor 15h and the light source 7h are exposed outward from the case bottom 2B. In this configuration example, the lens 4 is not provided. Then, the image sensor 15h and the light source section 7h are connected to the electronic circuit component 5 of the substrate 10 through wires 15c and 7c as electric wires, respectively. In this configuration example, illumination light is emitted downward from the light source section 7h based on control from the electronic circuit component 5, and the image sensor 15h receives and converts image light, which is reflected light from the mounting surface SF, into an image signal.

In embodiment 7, the transmission unit 6 is not an optical transmission mechanism, but is wires 15c and 7c as an electrical signal transmission mechanism. The image signal from the image sensor 15h is transmitted to the electronic circuit part 5 through the wiring 15 c. The light source control signal from the electronic circuit part 5 is transmitted to the light source section 7h through the wiring 7 c. In this example, the other end of the transmission unit 6 is electrically connected to the electronic circuit component 5, but the present invention is not limited thereto, and may be connected to the substrate 10, and may be electrically connected to the electronic circuit component 5 and the like through a circuit of the substrate 10. The wiring 15c and the wiring 7c may be covered with the fourth heat insulating layer 24 or the like. The wiring 15c and the wiring 7c which form the transmission unit 6 are front-side wirings in this example, but the present invention is not limited thereto, and the above-described various forms can be applied.

In the configuration of embodiment 7 shown in (a), the image sensor 15h and the light source unit 7h are some of the components that are arranged apart in the longitudinal direction and the horizontal direction from the center portion of the case bottom portion 2B toward the front side of the mouse 1, and have, for example, heat insulation, heat resistance, water resistance, pressure resistance, contamination prevention, easy cleaning, and the like. The electronic circuit component 5, which is a separate component and does not receive heat, is disposed at a separate position within the housing 2, for example, at a position near the center of the internal space of the housing 2, through the wiring 15c, which is the transmission unit 6, from the image sensor 15h or the like. Thus, the electronic circuit component 5 and the like sufficiently avoid heat and the like from entering the mouse 1 from the portions of the image sensor 15h and the light source unit 7h during the sterilization process. A sealing material or a heat insulating material may be provided in the vicinity of the image sensor 15h and the light source unit 7 h.

In addition, when the third heat insulating layer 23 and the fifth heat insulating layer 25 are disposed below the substrate 10 as in the present embodiment, an important function of supporting and/or fixing the substrate 10 can be achieved.

[7-2: modification example

Fig. 23 (B) shows a modification of embodiment 7. In this modification, the image sensor 15h, the light source unit 7h, and the lower cover 2601 are provided in the housing bottom portion 2B. The wiring 15c and the wiring 7c extend upward, are covered with the fifth heat insulating layer 25, and are connected to the lower surface of the substrate 10 in the second heat insulating layer 22. In this modification, compared to the configuration of (a), the image sensor 15h and the light source unit 7h have a cover 2601 on the lower side of the image sensor 15h and the light source unit 7h for reinforcing the possibility of heat and water during sterilization treatment from the deficiency of heat insulation, heat resistance, water resistance, pressure resistance, contamination prevention, easy cleaning property, and the like. The cover 2601 is also translucent and transmits illumination light and image light. A sealing material or a heat insulating material may be provided near the cover 2601. The cover 2601 is provided to cover at least the lower surfaces of the image sensor 15h and the light source unit 7h and to be smooth with respect to the lower surface of the housing bottom 2B. That is, the cover 2601 has light transmittance, heat insulating property, heat resistance, water resistance, pressure resistance, contamination resistance, easy cleaning property, and the like. The cover 2601 may be provided to cover the entire housing bottom 2B or the like. The cover 2601 is not limited to one sheet, and may be formed of a plurality of layers including a cover having heat insulation properties and a cover having water resistance properties. As described above, in this modification, the necessary heat resistance, water resistance, and the like are ensured by the combination of the arrangement position of the image sensor 15h and the like provided near the left end of fig. 23 of the case bottom portion 2B and the arrangement of the cover 2601.

In addition, when the third heat insulating layer 23 and the fifth heat insulating layer 25 are disposed below the substrate 10 as in the present embodiment, an important function of supporting and/or fixing the substrate 10 can be achieved.

< embodiment 8>

A mouse according to embodiment 8 of the present invention will be described with reference to fig. 24. The mouse according to embodiment 8 shows an example of a configuration in which the substrate 10 is formed in a box shape or the like.

[8-1: base plate of box shape

Fig. 24 (a) shows a cross-sectional view of a mouse 1 as a mouse according to embodiment 8. In the internal space of the casing 2 and the first thermal insulation layer 21, a transfer portion 6, not shown, is connected to the lens 4 of the casing bottom portion 2B, and is connected to the image sensor 15 of the electronic circuit component 5 on the substrate 10. The wiring of the transmission unit 6 can be applied to the above-described respective modes. The case bottom 2B and the substrate 10 are arranged at a distance K2 with the fifth heat insulating layer 25 or the second heat insulating layer 22 therebetween. The substrate 10 has a substantially box shape, and includes a bottom surface portion 10b arranged on a horizontal plane and, for example, four side surface portions 10a (side surface portions on the Y-Z plane in fig. 24) standing in the Z direction. The box-shaped upper surface portion (in other words, the cover portion) of the substrate 10 is not provided. Components such as the electronic circuit component 5 are mounted on the bottom surface portion 10b of the substrate 10. The electronic circuit component 5 is disposed, for example, in the vicinity of the center in the case 2 and covered with the third heat insulating layer 23. Further, another member 10p may be attached to the inner surface side of the side surface portion 10a of the substrate 10.

In this example, the box shape of the substrate 10 is a rectangular parallelepiped shape having four side surface portions 10a, and has a quadrangular shape in a cross section viewed from a top view. In addition, regarding the box-like structure of the substrate 10, it is necessary to: the surface area of the box shape is reduced as much as possible to reduce heat intrusion, and the distance between the box shape of the substrate 10 and the inner surface of the casing 2 is set as far as possible to reduce generated heat conduction, thereby making it possible to increase the amount of insertion of the heat insulating material into the space inside the casing 2, particularly the first space portion SP1 in which the fifth heat insulating layer 25 is provided. Therefore, the size of the box shape of the substrate 10 is further reduced to the three-dimensional shape formed by the inner surface of the housing 2 as much as possible, and the shape of the box shape of the substrate 10 is preferably a spherical shape or a prolate spherical shape (a rotational ellipse shape), or a spherical shape having a part of a plane, a prolate spherical shape, or a polyhedron similar thereto, in addition to the above shapes. Specifically, the shortest distance between the inner surface of the case 2 and the outer surface of the base plate 10, such as the box shape, is 3 to 20mm, preferably 13 to 20 mm.

The bottom surface portion 10b has a predetermined distance K91 in the X direction, for example. The side surface portion 10a has a predetermined height (distance K92) in the Z direction, for example. A distance K93 is provided from the upper end of the side surface portion 10a to the upper surface of the case upper portion 2A. A third space portion SP3 is formed in the box-shaped substrate 10. A fourth space SP4 is formed between the outside of the side surface portion 10a and the housing 2. In the fourth space portion SP4, for example, a distance K94 is provided from the side surface portion 10a to the outer surface of the housing 2 in the X direction. Thus, the box-shaped substrate 10 is concentrated at a position near the center of the internal space of the housing 2 and is arranged to be compact. Thus, in this configuration, heat conduction from the outer surface of the case 2 in various directions is difficult for components such as the electronic circuit component 5. In particular, in this configuration, since the distance K94 and the like of the fourth space portion SP4 are ensured in each horizontal direction and intervene in the side surface portion 10a, heat conduction in each horizontal direction is difficult. By reducing the surface area of the substrate 10 (the surface area of the outer surface of the box shape), the amount of heat conduction is reduced, thereby improving the heat insulating performance for protecting the electronic circuit component 5 and the like.

In the configuration example of (a), the substrate 10 is surrounded by the second heat insulating layer 22. As a modification, the second heat insulating layer 22 may be omitted. Alternatively, the outer surface of the box-shaped substrate 10, for example, the outer surface 10s1 of the bottom surface portion 10b and the outer surface 10s2 of the side surface portion 10a, may be heat-insulating coated. The third space portion SP3 may be closed by providing a box-shaped upper surface portion. Thus, in embodiment 8, the case-shaped substrate 10 reduces the volume ratio of the substrate 10 to the entire internal space of the mouse, improves the heat insulation of the substrate 10 itself, makes it difficult to conduct heat to the electronic circuit component 5 and other components, and improves the overall heat insulation effect. In addition, this can reduce the arrangement of other members such as a heat insulating layer.

(B) A modification of embodiment 8 is shown. The substrate 10 in this modification has a substantially cylindrical shape, a cylindrical shape, and a cylindrical upper surface portion 10c (in other words, a lid portion). Third space portion SP3 is closed by upper surface portion 10 c. The side surface portion 10a of the cylindrical substrate 10 may be curved, and may be rounded to form a cylindrical shape using a flexible (elastic) member such as a flexible printed circuit board. The component may be mounted on the inner surface side in the upper surface portion 10 c. The cylindrical upper surface portion 10c may be omitted. The box-shaped or cylindrical substrate 10 may be formed by connecting a plurality of substrates.

In this modification, heat conduction from the outside to the components such as the electronic circuit component 5 in the third space portion SP3 is difficult by the cylindrical closed substrate 10. The second heat insulating layer 22 is not provided in this modification in accordance with the amount thereof. The outer surface of the cylindrical substrate 10, for example, the outer surface 10s1 of the bottom surface portion 10b, the outer surface 10s2 of the side surface portion 10a, and the outer surface 10s3 of the upper surface portion 10c may be heat-insulating coated. In this example, a case is shown in which the heat insulating coating 2601 shown by a dotted line is provided on the entire outer surface of the substrate 10. The thickness of the heat insulating coating 2601 is less than the thickness of the second heat insulating layer 22 of (a). In this example, the substrate 10 and the like are positioned by the fifth heat insulating layer 25 provided in the first space portion SP 1. That is, when the fifth insulating layer 25 is disposed below the substrate 10 as in the present embodiment, it is possible to realize an important function of supporting and fixing the substrate 10. Not limited to this, the thermal insulating material, the heat absorbing material, or the filler may be disposed in the second space portion SP2 and the fourth space portion SP4, and the substrate 10 and the like may be positioned.

< embodiment 9>

Fig. 26 is a schematic sectional view in a plan view showing one embodiment 9 of a tablet terminal or a PC as another example of the electronic device of the present invention, fig. 27 is a plan view of the tablet terminal of fig. 26, and fig. 28 is a schematic sectional view taken along line D1-D1 of fig. 26.

This example is a tablet terminal using a terminal called so-called iPad (trade name: registered trademark) as a representative example.

In this case, the structure of the mobile terminal, the arrangement of the optical element, the imaging element, and the electronic circuit component, and the like are substantially the same as those of the digital tablet terminal, and therefore, illustration and detailed description thereof are omitted.

In the present embodiment, the tablet terminal 101 includes: a housing 102 composed of a housing upper part 102A and a housing bottom part 102B; various electronic components such as a charging coil 103 disposed in the internal space of the housing 102; two secondary batteries 104; an electromagnetic sensor 106 for acquiring discrimination information of an object or the like; a substrate 107; an IC chip 108 as an electronic circuit component disposed above the substrate 107; and an image capturing section 109 which is an electronic circuit component also mounted above the substrate 107.

In the present embodiment, the two secondary batteries 104, the electromagnetic sensor 106, the substrate 107, the IC chip 108, and the image capturing section 109, which are electronic components, are surrounded by the heat insulating material 105, and the heat insulating effect of these electronic components is further improved. The heat insulating material 105 or the same type of heat insulating material may be disposed not only to surround the electronic components but also to have a laminated structure inside or outside the case 102, or the case 102 may be formed in multiple layers and the heat insulating material 105 may be disposed as an intermediate layer thereof. In addition, a heat insulating structure similar to or related to the embodiment illustrated in fig. 1 to 25 may be combined.

An opening 110 is formed on the rear surface side of the tablet terminal 101, that is, in the present embodiment, at one corner portion (upper right in fig. 26) of the case bottom portion 102A, and a camera lens 111 for photography, which is an optical element or an imaging element, is fitted into the opening 110.

The camera lens 111 is optically connected to the image capturing unit 109 via the transmission unit 112. The transmission section 112 can be formed of an optical fiber such as a glass fiber.

A monitor screen 113 is provided on the front surface side, i.e., the flat surface side, of the tablet terminal 101 (fig. 27). Unlike the case of an electronic device such as a general tablet terminal or a mobile terminal, the monitor screen 113 has a small area, for example, half or less, with respect to the planar area of the housing 102. The reason for this is as follows. That is, since the heat insulating structure is surely provided for a high temperature at the time of sterilization in the autoclave device, the volume or thickness of the inside of the case at the portion where the monitor screen is located is reduced. If the monitor screen is enlarged, the thickness is increased by that amount, making it difficult to use. Therefore, by reducing the monitor screen 113, a strong heat insulating structure is established at a thick portion where the monitor screen 113 is absent, and heat is avoided by accommodating electronic components and the like at that portion. However, with the improvement of heat insulation technology and heat resistance of electronic devices, the digital board terminal 101 becomes thin and the monitor screen 113 becomes large, and thus development of easy use is expected. Therefore, the thickness of the tablet terminal 101, the size of the monitor screen 113, and the like are merely examples, and are not limited to these examples.

Reference numeral 114 in fig. 26 denotes a screw for a strut in the housing 102, and a plurality of screws 114 are arranged in the housing 102.

The tablet terminal 101 of the present embodiment is also a tablet terminal that can withstand severe processing conditions such as sterilization processing by high-temperature and high-pressure steam in a medical autoclave device, and can be applied to a special electronic device such as a medical field, as in the case of the mouse 1 of the above-described embodiment, completely different from electronic devices for input and operation in a general office computer.

Therefore, in the digital board terminal 101, in order to prevent the influence of heat, high pressure, and the like caused by high-temperature and high-pressure water vapor in the autoclave treatment to the maximum extent by the substrate 107 on which the IC chip 108 and the image capturing section 109 are mounted, particularly the IC chip 108 and the image capturing section 109, which are electronic circuit components, the first space SP1 is disposed so as to be spaced apart from the opening 110 and the camera lens 111 for photography to the maximum extent in the Z direction by the amount of the first space SP1, thereby preventing the influence of heat, high pressure, and the like caused by high-temperature and high-pressure water vapor in the autoclave treatment to the maximum extent.

That is, as shown in fig. 28, in the Z direction which is the vertical direction of fig. 28, a distance K1 which is the distance between the lower surface of case bottom portion 102B and the lower surfaces of IC chip 108 and image capturing unit 109 as electronic circuit components, and a distance K2 which is the distance between the upper surface of case bottom portion 102B and the lower surface of substrate 107 in the Z direction, second space portion SP2 above IC chip 108 and image capturing unit 109 is maximally increased with respect to a distance K3 between the upper surfaces of IC chip 108 and image capturing unit 109 and the outer surface of case upper portion 102A in the Z direction.

Further, the IC chip 108 and the image capturing section 109, which are electronic circuit components, are spaced apart from the case upper portion 102A of the case 102 by the amount of the second space portion SP2 in the Z-direction downward direction, and the influence of heat, high pressure, and the like due to high-temperature and high-pressure water vapor in the autoclave process can be prevented.

In the tablet terminal 101 according to the present embodiment, the substrate 107, the IC chip 108 as an electronic circuit component, and the image capturing section 109 are disposed at a maximum distance of K8 (fig. 28) in the X direction (the lateral direction in fig. 26 and 28, that is, the short side direction) from the opening 110 and the camera lens 111 for photographing as an optical element or an imaging element. In other words, the distances K4B1 and K4B2 from the outer surfaces of the left and right sides (fig. 26) of the housing 102 of the tablet terminal 101 to the image capturing section 109 are such that the distance K4B1 on the camera lens 111 side is maximally greater than the distance K4B2 on the opposite side.

In the tablet terminal 101 according to the present embodiment, the substrate 107, the IC chip 108 as an electronic circuit component, and the image capturing section 109 are disposed at a maximum distance K7 (fig. 26) in the Y direction (the vertical direction in fig. 26, that is, the longitudinal direction) orthogonal to the X direction from the opening 110 and the camera lens 111 for photographing as an optical element or an imaging element. That is, in the longitudinal direction of the tablet terminal 101, as shown in fig. 26, a distance K7+ K6 obtained by adding up a distance K7 from the image capturing section 109 to the photographing lens 111 and a distance K6 from the photographing lens 111 to the end surface on the opposite side to the longitudinal direction of the housing 102 is as large as possible as compared with a distance K4A from the end surface on the near side in the longitudinal direction of the housing 102 to the image capturing section 109 (K7+ K6> K4A).

Therefore, when viewed from the three directions of the Z direction, the X direction, and the Y direction, the substrate 107, the IC chip 108 as an electronic circuit component, and the image capturing section 109 are disposed at a maximum distance from the opening 110 and the camera lens 111 for photographing as an optical element or an imaging element by the amount of the first space SP1 in the Z direction, at a maximum distance from the X direction by the distance K8 (fig. 28), and at a maximum distance from the Y direction by the distance K7 (fig. 26).

That is, in the tablet terminal 101 of the present embodiment, the substrate 107 on which the IC chip 108 and the image capturing section 109 are mounted, particularly the IC chip 108 and the image capturing section 109 as electronic circuit components, are arranged at a maximum distance from the opening 110 and the camera lens 111 for photographing in the Z direction, the X direction, and the Y direction, respectively, so as to be arranged at a maximum distance from each other in three dimensions, and as a result, the influence of heat, high pressure, and the like due to high-temperature and high-pressure water vapor in autoclave processing can be prevented to the maximum.

In other words, the tablet terminal 101 according to embodiment 9 is a medical tablet terminal, and can be applied to autoclave sterilization for improving the sanitary environment of a medical site such as a hospital, and when a medical equipment system to which the tablet terminal is connected is desired to be used in an examination, an operation, or the like, for example, infection is reliably prevented by using the tablet terminal subjected to sterilization, and advanced medical care can be realized using the functions of the system such as navigation technology. For example, a three-dimensional image can be more reliably obtained by operating the tablet terminal by the operator himself/herself, and the quality of the operation and the like can be improved. The tablet terminal not only has an optical tablet terminal function, but also can be applied to sterilization such as autoclave treatment together with medical instruments in a use environment such as a medical field, thereby achieving effects such as prevention of infection and improvement of medical efficiency.

< embodiment 10>

Fig. 29 is a schematic sectional view in a planar direction of an embodiment 10 of an intraoral camera which is another example of an electronic device according to the present invention, fig. 30 is a bottom view of the intraoral camera of fig. 29, fig. 31 is a sectional view taken along line D2-D2 of fig. 30, and fig. 32 is a view taken along line D3-D3 of fig. 31.

This example is applied to a so-called intra-oral camera as another example of the medical electronic apparatus of the present invention.

In the present embodiment, the intra-oral camera 201 includes: a housing 202 including a main body 202A and an extension 202B extending from the main body 202A; various electronic components such as a charging coil 203 disposed in the housing 202; two secondary batteries 204; a heat insulating material 205; an electromagnetic sensor 206; a substrate 207; an IC chip 208 as an electronic circuit component disposed above the substrate 207; and an image capturing section 209, which is an electronic circuit component, also mounted above the substrate 207.

In the present embodiment, the two secondary batteries 204, the electromagnetic sensor 206, the substrate 207, the IC chip 208, and the image capturing section 209, which are electronic components, are surrounded by the heat insulating material 205 schematically shown by the two-dot chain line, and the heat insulating effect of these electronic components is further improved. The heat insulating material 205 or the same type of heat insulating material may be disposed not only to surround the electronic components but also to have a laminated structure inside or outside the case 202, or the case 202 may be formed in a plurality of layers and the heat insulating material 205 may be disposed as an intermediate layer. The present invention may be combined with the same or related heat insulating structure as the embodiments illustrated in fig. 1 to 25 and 26 to 28.

An opening 210 is formed on the back side of the distal end of the extension 202B of the intraoral camera 201, and a camera lens 211 for photographing as an optical element or an imaging element is fitted into the opening 210.

The camera lens 211 is optically connected to the image capturing unit 209 via a transmission unit 212 inserted into the extension unit 202B. The transmission section 212 can be formed of an optical fiber such as a glass fiber.

The intra-oral camera 201 of the present embodiment is also completely different from electronic devices for input and operation in a general office computer, and can withstand severe processing conditions such as sterilization treatment with high-temperature and high-pressure water vapor in an autoclave device for medical use, and can be used as an intra-oral camera suitable for a special electronic device in a medical field or the like, similarly to the mouse 1 and the tablet terminal 101 in the above-described embodiments.

Therefore, in the oral camera 201, the substrate 207 on which the IC chip 208 and the image capturing section 209 are mounted, particularly, the IC chip 208 and the image capturing section 209 as electronic circuit components, the opening 210 at the distal end of the extension section 202B, and the camera lens 211 for photographing are disposed at a maximum distance in the Y direction (longitudinal direction of the oral camera 201). Thus, in the oral camera 201 of the present embodiment, the influence of heat, high pressure, and the like caused by high-temperature and high-pressure water vapor in the autoclave treatment can be prevented to the maximum.

In the oral camera 201 of the present embodiment, the first space portion SP1 is disposed at a maximum distance in the Z direction from the lower outer surface (bottom surface) of the housing 202, so that the influence of heat, high pressure, and the like caused by high-temperature and high-pressure water vapor in the autoclave treatment can be prevented to the maximum. That is, the distance K1 from the lower outer surface (bottom surface) of the case 202 to the lower surface of the substrate 207 becomes as large as possible with respect to the distance K3 from the upper outer surface (upper surface) of the case 202 to the upper surface of the substrate 207.

Further, the IC chip 208 and the image capturing section 209, which are electronic circuit components, are spaced apart from the upper outer surface of the housing 202 in the Z direction by the amount of the second space section SP2, and thus, the influence of heat, high pressure, and the like caused by high-temperature and high-pressure water vapor in the autoclave treatment can be prevented.

In the intraoral camera 201 of the present embodiment, the substrate 207, the IC chip 208 as an electronic circuit component, and the image capturing section 209 are disposed at a maximum distance from the opening 210 and the camera lens 211 for photographing as an optical element or an imaging element in the X direction (the lateral direction in fig. 32, that is, the short-side direction).

That is, for example, as shown in fig. 32, the image capturing section 209 is spaced from the left outer side surface of the housing 202 by a distance K4B1 in the X direction and spaced from the right outer side surface of the housing 202 by a distance K4B2, so that the distance K4B1 is larger than the distance K4B2 (K4B1> K4B2), and the distance K4B1 is larger than that in the case where the image capturing section 209 is located at the center of the housing 202 in the X direction, and the image capturing section 209 is also spaced from the camera lens 211 as far as possible in the X direction.

As shown in fig. 32, in the substrate 207, a distance K4G1 from the left end of the substrate 207 to the left outer surface of the case 202 is larger than a distance K4G2 from the right end of the substrate 207 to the right outer surface of the case 202 (K4G1> K4G 2).

Therefore, in the present embodiment, the substrate 207, the IC chip 208 as the electronic circuit component, and the image capturing section 209 are disposed at a maximum distance from the opening 210 and the camera lens 211 for photographing as the optical element or the imaging element in all directions of the X direction, the Y direction, and the X direction, as viewed from three directions of the Z direction, the X direction, and the Y direction.

That is, in the oral camera 201 of the present embodiment, the substrate 207 on which the IC chip 208 and the image capturing section 209 are mounted, particularly, the IC chip 208 and the image capturing section 209, which are electronic circuit components, are disposed at a maximum distance from the opening 210 and the camera lens 211 for photography in the Z direction, the X direction, and the Y direction, respectively, so that they are disposed at a maximum distance from each other in three dimensions, and as a result, the influence of heat, high pressure, and the like caused by high-temperature and high-pressure water vapor in autoclave treatment can be prevented to the maximum.

In other words, the oral camera 201 according to embodiment 10 is not only capable of being used for sterilization by an autoclave, but also capable of achieving effects such as prevention of infection and improvement of medical efficiency by using the sterilized oral camera in a medical field.

In particular, in the case of the oral camera 201 according to the present embodiment, in addition to the above-described structure in which the opening 210 and the electronic circuit components such as the camera lens 211 and the image capturing unit 209 are separated from each other, the distance from the opening 210 and the camera lens 211 for photographing, which is an optical element or an imaging element, to the substrate 207 and the IC chip 208 and the image capturing unit 209, which are electronic circuit components, is very long due to the presence of the extension portion 202B, and therefore, even during the sterilization process in the autoclave apparatus, it is possible to more effectively prevent heat at high temperature, high pressure, and the like from being transmitted from the opening 210 and the camera lens 211 to the substrate 207 and the IC chip 208 and the image capturing unit 209, which are electronic circuit components.

The present invention has been described specifically based on the embodiments, but the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

The embodiments of fig. 1 to 25, 26 to 28, and 29 to 32 are also included in the scope of the present invention, and the disclosure thereof is applicable to, for example, a heat insulating structure, a structure of an optical lens, and the like, in combination with each other, or in use of each other.

[ possibility of Industrial utilization ]

The electronic device of the present invention can be widely applied to electronic devices other than a mouse, a tablet terminal, and an intra-oral camera.

For example, the present invention can be applied to the following electronic devices.

Although it has been impossible to sterilize by an autoclave because of the electronic components included in a part thereof, there is a demand for medical equipment (in the field of health care of living organisms such as human bodies, animals, and microorganisms) capable of sterilization.

First, when the autoclave sterilizer is large and cannot be accommodated therein, it is assumed that only parts having a high contamination frequency are detachably sterilized. Such as an operation panel, etc., can be easily realized. Alternatively, the present invention is also intended to be modified to be disassembled and miniaturized by other components so that the autoclave apparatus can perform sterilization operation. This is because, when these devices are contaminated with pathogenic bacteria of a serious infection or the like, there is a possibility that infection amplification must be prevented by strong chemical liquid, gas sterilization, incineration, or the like, except for sterilizable parts such as an autoclave device. Medical treatment refers to health care and research of the whole organism, such as animals, microorganisms, veterinary medicine, biology, genetic gene therapy, genetic engineering, pharmacy, drug delivery, and research of other infections, as well as the whole organism.
