Disclosure of Invention

Conventionally, in connection with medical instruments and the like used in medical sites, sterilization, disinfection, etc. are performed at a necessary level in order to prevent infection. Examples of the sterilization treatment include autoclave treatment. In the autoclave treatment, the object is exposed to a predetermined high-temperature and high-pressure water vapor for a predetermined time or longer. In order to prevent infection, a medical mouse is also required to be sterilized, and sterilization is more desirable, and heat resistance, water resistance, pressure resistance, water resistance, and the like are required.

However, the conventional optical mouse for general use cannot withstand the sterilization treatment by high-temperature and high-pressure steam, such as the autoclave treatment. The optical mouse includes components such as electronic circuit components that are not heat-resistant and waterproof. In order to realize the mouse function, the optical mouse is provided with components such as a lens, an image sensor, an electronic circuit component, a light source unit, and a power supply unit in contact with the bottom of the case. Therefore, when the optical mouse is subjected to the autoclave treatment, heat of high-temperature and high-pressure steam is directly transferred to components such as electronic circuit components in the case, particularly, through an opening in the bottom of the case, and the steam is likely to enter, and as a result, damage to the components becomes large, and the mouse function cannot be realized.

The object of the present invention is to provide a special electronic device such as a mouse, a digital tablet terminal, and a mobile terminal, which can withstand severe processing conditions such as sterilization processing by high-temperature and high-pressure steam in an autoclave device, and which is suitable for use in medical sites and the like, in contrast to general electronic devices for input and operation in business computers.

Representative embodiments of the present invention have the following configurations. That is, an electronic device according to an embodiment can be used in a medical field, and includes: a housing; a substrate disposed in an inner space of the housing; an electronic circuit component composed of an electronic element mounted on the substrate; an optical element or an imaging element disposed in a part of the housing, and configured to receive image light from the outside as an optical signal; and a transmission unit that connects the optical element or the imaging element to the electronic circuit component, wherein the image light or an electric signal corresponding to the image light can be transmitted between the optical element or the imaging element and the electronic circuit component, and the substrate and the electronic circuit component are arranged to be separated from a part of the housing in which the optical element or the imaging element is arranged via a first space.

According to the representative embodiment of the present invention, an electronic device such as a mouse, a tablet terminal, a mobile terminal, or the like can be obtained, and the electronic device can withstand sterilization treatment by high-temperature and high-pressure steam in an autoclave apparatus, and can be used for medical sites or the like, and is useful for preventing infection, improving medical efficiency, and the like.

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 duplicate descriptions are omitted.

< Embodiment 1>

A mouse according to embodiment 1, which is an example of an electronic device of the present invention, will be described with reference to fig. 1 to 6. The mouse of embodiment 1 is a medical mouse which improves the hygienic environment of a medical field such as a hospital and can be sterilized by an autoclave, in other words, a sterilizable mouse. In the case of examination, surgery, or the like, there are cases where a system including a computer to which a mouse is connected and medical equipment is desired to be used. In this case, by using the sterilized mouse, it is possible to reliably prevent infection and to realize advanced medical treatment using a system function such as a navigation technique. For example, a person performing an operation can actually obtain a three-dimensional image by operating a mouse, and the quality of the operation and the like can be improved. 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 use environments such as medical sites, thereby obtaining effects such as preventing infection and improving medical efficiency.

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

[1-1: Mouse whole body

Fig. 1 is a perspective view showing the overall appearance of a mouse 1 as a mouse of 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 portion 2A and a housing bottom portion 2B. The housing upper portion 2A is a portion gripped by the hand of the user, and has a generally elliptical curved surface shape or a free curved surface shape. A button (sometimes referred to as a switch button, a click button, or the like) 3 for input operation, for example, two left and right buttons 3 are provided at a front position of the housing upper portion 2A. The button 3 is a button that can be pressed by a finger in response to an operation such as clicking by a user. Although the two-button system is shown, the present invention is not limited to this, and may include a system having any number of buttons, such as one button and three buttons. The case bottom 2B is a substantially flat plate-shaped portion provided on the mouse mounting surface. In the case bottom 2B, an opening R1 in which an optical element or the like is provided at a position offset from the central position of the housing 2 in one of the longitudinal directions. The case upper part 2A and the case bottom part 2B are joined after internally accommodating components at the time of mouse manufacturing. The mouse 1 of embodiment 1 is a wireless communication type and wireless charging type mouse, and has a structure 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 a transmission section 6; (b) wiring the transfer section 6 in the housing 2 via the front side surface; and (c) providing a light source section 7, a power supply section 8, and the like. In addition, this configuration example shows that (d) when one electronic circuit component 5 is provided on the substrate 10, (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 in a horizontal plane is as follows: the electronic circuit component 5 is disposed at a position (a position on the right side in the opposite direction to the position of the left opening R1 in fig. 3) which is as far apart as possible from the opening R1 in the longitudinal direction of the case 2 among the positions on the substrate 10, and prevents heat conduction due to invasion of heat from the outside of the mouse through the opening R1. (f) Further, not only the electronic circuit component 5 but also the light source unit 7 and the power source unit 8 are disposed above the substrate 10, and heat can be prevented as much as possible from entering the substrate 10 from below from outside the mouse via the opening R1. (g) As shown in fig. 3, the planar shape of the substrate 10 is formed into a substantially elliptical shape similar to the substantially elliptical shape that is the shape of the inner surface of the structural surface of the housing 2, and as will be described later, the distance from the structural surface of the housing 1 is made as uniform and large as possible over the entire circumference of the substrate 10, so that heat that has entered from the outside through the structural 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 the sake of clarity of explanation.

[1-2: Mouse longitudinal section

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

The push button 3 of the housing 2 shows a structure of the type without a lever or the like in fig. 2. The button 3 is electrically connected to the electronic circuit part 5 of the substrate 10 through a wiring 3c (for example, 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 button 3 is made of, for example, a soft (elastic) resin or the like, and is deformed into a concave-convex shape in response to a user's pressing operation. A switching circuit, not shown, on the lower side of the button 3 is electrically turned on/off in response to the deformation of the button 3, and an on/off signal is output from the wiring 3 c. The button 3 may be formed as a part of the housing 2.

The mouse 1 has elements such as a lens 4, a substrate 10, a light source unit 7, a power source unit 8, and a transmission unit 6 disposed in a housing 2. The functions of the optical mouse of the mouse 1 are mainly constituted by connection of the lens 4, the transmission unit 6, the image sensor 15 (fig. 5 described in detail later), and the electronic circuit component 5. The internal space of the housing 2 is substantially divided into a first space portion SP1 located on the lower side of the substrate 10 and a second space portion SP2 located on the upper side of the substrate 10. A lens 4 is disposed in the opening R1 of the bottom 2B of the case. The lens 4 is an optical element (in other words, an image light incident portion) which is disposed in a part (opening portion R1) of the case bottom 2B and which is configured to receive light (image light) from the outside as an optical signal. The lens 4 is not limited to one lens, and may be constituted by a plurality of lenses, or may have a member such as a mirror. The lens 4 is fixed in close contact with the bottom 2B of the case. The lens 4 collects light from the installation surface SF outside the housing 2 as image light (optical signal) and makes the image light incident on one end of the transmission unit 6.

An electronic component such as the electronic circuit component 5 is 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 and water (water vapor) during the sterilization process. The electronic circuit part 5 shows a case where a controller, a wireless communication function, a wireless charging control function, and the like are integrally implemented as a mouse function. The controller of the electronic circuit unit 5 controls image processing of an image using 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, etc. The controller transmits information indicating the state of the mouse 1 to an external computer or the like through a wireless communication circuit. Although only one electronic circuit component 5 is shown, 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 will be described later.

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

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 member 5 on the upper surface side of the substrate 10 via, for example, wiring near the front surface in the case 2.

The light source unit 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 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 part 5 controls the light emission of the light source section 7 by the light source control signal. The arrangement position of the light source unit 7 may be arbitrary and is not limited. The illumination light from the light source section 7 is supplied to the lens 4 through, for example, the light source section wiring 7 d. Further, an optical member such as a light guide may be used to supply illumination light. For example, the light source section wiring 7d may be an optical fiber 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. In addition, 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 section 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, near the center. The power supply unit 8 supplies power to each part of 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 includes a circuit for receiving wireless charging and a secondary battery between the wireless charging unit and a wireless power supply unit of the installation surface SF (for example, a mouse pad) in a wireless charging manner. The present invention is not limited to the wireless charging method, and known methods such as a magnetic field coupling method, an electric field coupling method, a laser method, a microwave method, and an ultrasonic method can 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 terminals are exposed on the outer surface of the case 2. In this case, the exposed terminals are smoothed with respect to the main surface of the housing bottom 2B, for example. By smoothing it, it has a property of being difficult to attach a stain (stain-proofing property) and a property of being easy to remove a stain (easy to clean).

The power supply unit 8 is disposed above the substrate 10 as a whole in this example. As shown in the embodiment and the modified example described below, 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 source 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 case 2. In the case 2, a plurality of substrates may be arranged in a horizontal direction or may be arranged in a vertically overlapping manner. The plurality of substrates may be formed into a three-dimensional stepped layered structure. The substrates may be arranged vertically in the case 2 or may be arranged obliquely to the horizontal. In the case of dividing into a plurality of substrates, the arrangement position can be easily and in detail divided according to the temperature and the degree of heat insulation of each component.

By using the optical fiber 6f as the transmission unit 6, the mouse 1 can be separated as far as possible from the portion of the housing 2 such as the lens 4 of the opening R1 of the housing bottom 2B, and the portion of the image sensor 15 and the electronic circuit component 5. In embodiment 1, the electronic circuit component 5 and the like are disposed in the case 2 at positions near the right end in the longitudinal direction (positions on the rear side of the mouse 1) in this example, and are preferably separated as far as possible from the opening R1 provided near the one end in the longitudinal direction of the case bottom 2B (positions near the left end and on the front side of the mouse 1 in fig. 2 and 3). Accordingly, the length of the optical fiber 6f is also increased, and therefore, the amount of heat or the like transferred 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.

As a result, in the mouse 1 of the present embodiment 1, the positional relationship between the lens 4 of the opening R1 and the electronic circuit member 5 and the image sensor 15 on the substrate 10 in a plan view as a horizontal plane is such that the electronic circuit member 5 is disposed at a position where the opening R1 is separated as far as possible in the longitudinal direction of the housing 2 from the position on the substrate 10 (a position on 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), that is, a position on the right side of fig. 3), so that heat conduction due to invasion of heat from the outside of the mouse through the opening R1 can be prevented as much as possible, and therefore even in a case where the mouse 1 is subjected to sterilization processing by high-temperature and high-pressure steam in an autoclave device, for example, heat that has invaded from the outside of the mouse is conducted to the electronic circuit member 5 and the image sensor 15 through the opening R1 and the lens 4 can be prevented as much as possible from being damaged or broken.

As shown in fig. 3, the planar shape of the substrate 10 is formed into a substantially elliptical shape similar to the substantially elliptical shape of the frame 2, so that the distance from the inner surface of the structural surface of the frame 2 is as uniform and large as possible over the entire circumference of the substrate 10, and heat and the like entering from the outside through the structural surface of the frame 2 can be prevented as much as possible, and in this regard, the substrate 10 is formed into a substantially elliptical shape so that the area of the substrate 10 is as small as possible, and heat accumulated in the substrate 10 cannot be conducted to the electronic circuit component 5 and the like by heat conduction. As a result, even if the surface of the substrate 10 is a flat surface, accumulation of heat on 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 in the above description, fig. 2, fig. 3, and the like, the electronic circuit member 5, the light source unit 7, and the power source unit 8 are all disposed above the substrate 10. As a result, even when the mouse 1 is subjected to the sterilization treatment by the high-temperature and high-pressure steam in the autoclave device, the electronic circuit member 5, the light source unit 7, and the power source unit 8 are all separated from the housing bottom 2B by a distance K1 or more described below, so that the influence of the high-temperature and high-pressure steam and moisture is prevented from being transmitted to all of the electronic circuit member 5, the light source unit 7, and the power source unit 8, and all of the electronic circuit member 5, the light source unit 7, and the power source unit 8 can be protected from damage or failure due to the high-temperature and high-pressure steam.

In embodiment 1, the arrangement of the electronic circuit components 5 and the like in the housing 2 of the mouse 1 is important in order to avoid damage or failure due to high temperature and high pressure and water vapor, and therefore, the arrangement and distance in the X, Y, 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 2B and the lower surface of the electronic circuit part 5 in the up-down direction of fig. 2, i.e., the Z direction. The distance K2 is a distance between the upper surface of the case bottom 2B and the lower surface of the substrate 10 in the Z direction, and is a 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 2B to the upper side can be prevented. The mouse 1 is provided with the first space portion SP1 by using the transmission portion 6, and therefore, the heat insulation property 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 considering the heat insulation or the like can be selected.

In addition, the distance K3 is a distance between the upper surface of the electronic circuit part 5 and the outer surface of the housing upper part 2A in the Z direction of the second space portion SP2 in the upper side of the electronic circuit part 5. The distance K3 is also sufficiently ensured, and therefore the electronic circuit component 5 can be protected from heat or the like transmitted downward from the outside of the housing 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 (right end 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, in the Y direction which is the front-rear direction. In embodiment 1, the distance K4A is as short as possible, and the distance K6, which is the distance between the lower side surface of one end portion (the left end portion in fig. 2 and 3) in the longitudinal direction of the housing upper portion 2A and the opening R1 and the lens 4, is also as short as possible. As a result, in embodiment 1, the distance K7 in the horizontal direction between the opening R1 and the lens 4 and the electronic circuit member 5 is made as long as possible, that is, the opening R1 and the lens 4 and the electronic circuit member 5 are spaced as far as possible in both the horizontal direction and the vertical direction, and high heat or the like that has entered the mouse 1 from the portions of the opening R1 and the lens 4 does not reach the electronic circuit member 5 as much as possible.

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

As described above, in the mouse 1 of embodiment 1, 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 is set so that the lens 4 and the electronic circuit component 5 are spaced as far as possible in a plan view as a horizontal plane. That is, as described above, in fig. 2 and 3, the electronic circuit component 5 is disposed near the end portion on the right side in the longitudinal direction of the housing 2, and 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 contrast, the opening R1 and the lens 4 provided in the opening are disposed at a position where the distance between the left end portion of the electronic circuit component 5, which is the opposite side to the longitudinal direction of the housing 2, and the lower left surface of the housing upper portion 2A is K6. As a result, the horizontal distance between the opening R1 and the lens 4 and the electronic circuit component 5 is separated by the distance K7, but it is preferable that the distance K7 is as large as possible in order to prevent high heat or the like that has entered the case 2 through the opening R1 and the lens 4 from reaching the electronic circuit component 5 that is not subject to heat or the like. In embodiment 1, the above-described arrangement relation in which the distance K7 between the opening R1 and the lens 4 and the electronic circuit member 5 is as large as possible makes the opening R1 and the lens 4 and the electronic circuit member 5 furthest apart from each other in the horizontal direction and the vertical direction, and therefore, even when the mouse 1 is subjected to a sterilization process by high-temperature and high-pressure steam in an autoclave apparatus, for example, heat, pressure, and moisture entering the inside of the mouse 1 through the opening R1 and the lens 4 are prevented furthest from reaching the electronic circuit member 5 or the image sensor 15, and damaging or failing the electronic circuit member 5 and the image sensor 15, and the electronic circuit member 5 and the image sensor 15 which are not subjected to heat or the like can be protected furthest.

In addition, in embodiment 1, the opening R1 and the lens 4 are spaced apart from the electronic circuit member 5 in the vertical direction in the Z direction and in the Y direction in the horizontal direction, and in addition to this, as shown by the two-dot chain line in fig. 3, for example, the opening R1 and the lens 4 or the electronic circuit member 5 may be provided so as to be spaced apart from the center position in the longitudinal direction of the mouse 2 in either one of the Y direction in the horizontal direction and the X direction in the horizontal direction. Thus, the electronic circuit member 5 is spaced apart from the opening R1 and the lens 4 in all directions of the Y direction of the Z direction up and down direction and horizontal direction and the X direction of the horizontal direction. As a result, the distance between the electronic circuit member 5 and the opening R1 and the lens 4 becomes maximum in all of the Z direction, the Y direction, and the X direction in three dimensions, and heat and moisture entering the mouse 2 from the opening R1 and the lens 4 can be prevented from reaching the electronic circuit member 5 to the maximum extent.

In this case, since the positions of the opening R1 and the lens 4 or the electronic circuit member 5 which are displaced in the X direction are set to positions on opposite sides in the X direction as in the opening R1A and the lens 4A and the electronic circuit member 5B or the opening R1B and the lens 4B and the electronic circuit member 5A in fig. 3, and are separated to the maximum extent in the directions of all of the directions of the Z direction up and down direction and the horizontal direction and the X direction in the horizontal direction, the distance between the opening R1 and the lens 4 or the electronic circuit member 5 is set to the maximum in the all directions of the Z direction, the Y direction and the X direction, and the electronic circuit member 5 which is not heated is protected to the maximum extent.

As described above, in embodiment 1, as shown in fig. 3, the planar shape of the substrate 10 is not only formed into a substantially elliptical shape similar to the substantially elliptical shape of the inner surface of the structural surface of the housing 2, so that the distance from the structural surface of the housing 1 is separated as uniformly and largely as possible over the entire circumference of the substrate 10, heat or the like entering from the outside through the structural surface of the housing 2 is prevented as much as possible, and the area of the substrate 10 is reduced as much as possible, so that the heat accumulated in the substrate 10 is not conducted to the electronic circuit component 5 or the like by heat conduction, but also heat conduction is prevented 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 long-side direction and the short-side direction of the substrate 10 are also arranged to be spaced apart from the outer surface of the housing upper part 2A of the housing 2 of the mouse 1. That is, as shown in fig. 3, the horizontal separation distance in the Y direction of the substrate 10 is a distance K4C1 and K4C2 from the end faces (the right end face and the left end face in fig. 3) in the longitudinal direction (the front-rear direction) of the substrate 10 in fig. 3 to the outer surfaces of the housing upper part 2A in the longitudinal direction on the right and left sides, respectively.

In addition, as the horizontal separation distance of the substrate 10 in the X direction (the short side direction of the housing 2 of the mouse 1 in fig. 3, that is, the left-right direction, that is, the opposite side and the near front side when viewed from the right to the left in fig. 3), the distances K4D1 and K4D2, which are the distances from the side surface (the opposite side end surface and the near front side end surface in fig. 3) of the short side direction of the substrate 10 in fig. 3 to the outer surfaces of the short side direction right side (the opposite side in fig. 3) and the left side (the near front side in fig. 3) of the housing upper portion 2A of the housing 2 of the mouse 1, respectively, are separated. The distances K4C1 and K4C2 and the distances K4D1 and K4D2 are equal to each other, and thus the balance of heat resistance and the like is good, but may be different depending on the external and internal structures, component arrangement, use conditions, and the like of the housing 2 of the mouse 1.

Therefore, with the substrate 10 of embodiment 1, in addition to the planar shape of the substrate 10 being formed into a substantially elliptical shape similar to the substantially elliptical shape of the inner surface of the structural surface of the housing 2 as shown in fig. 3, the substrate 10 is not only spaced apart by the distance K1 (see fig. 2) from the outer surface of the housing bottom 2B of the housing 2 of the mouse 1, but also spaced apart by the distances K4C1 and K4C2, and the distances K4D1 and K4D2 between all the four end surfaces in the horizontal direction and the outer surface of the housing upper portion 2A of the housing 2 of the mouse 1 as shown in fig. 3, respectively, so that the substrate 10 is not only spaced apart sufficiently as much as possible from the structural surface of the housing 2 in the vertical direction but also in the horizontal direction, and heat conduction from the housing upper portion 2A and the housing bottom 2B of the housing 2 of the mouse 1 to the substrate 10 and heat accumulation to the substrate 10 can be suppressed to the maximum extent. As a result, heat conduction from the substrate 10 having a large mass to the electronic circuit component 5 having a small mass, the light source unit 7, the power source unit 8, the image sensor 15 and the like via the electronic circuit component 5 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 a distance between one end portion (left end portion in fig. 2) of the substrate 10 and the outer surface of the housing upper portion 2A closest to the one end portion. That is, the substrate 10 is spaced apart from the outer surface of the housing upper part 2A by a distance K5. In this case, in embodiment 1, the planar shape of the substrate 10 is formed into a substantially elliptical shape similar to the substantially elliptical shape of the inner surface of the structural surface of the frame 2, and therefore, the two end surfaces of the substrate 10 in the longitudinal direction are not linear but arc-shaped curved surfaces, and therefore, as compared with the case of the substrate 10 in which the two end surfaces are linear, the distance K5 between the two end surfaces of the substrate 10 in the longitudinal direction and the inner surface of the structural surface of the frame 2, that is, the length of the distance K5 can be as large as possible over the entire length of the two end surfaces. Accordingly, the distance K5 of the substrate 10 from the outer surface of the case upper part 2A is also sufficiently ensured, and thus heat conduction from the surface of the case upper part 2A to the end of the substrate 10 can be prevented.

Preferred examples of the distances K1 to K7 and the like

Here, in the preferred embodiments of the dimensions such as the distances K1 to K7, first, it is assumed that the overall height=30 to 50mm (preferably, for example, 40 mm), the overall length=80 to 130mm (preferably, for example, 110 mm), the overall width=45 to 75mm (preferably, for example, 55 to 65 mm) of the mouse 1 are the preferred embodiments, and in this case, the thicknesses of the substrate 10, the case 2, and the case bottom 2B are also considered, but the distances k1=10 to 25mm (preferably, for example, 12 to 20 mm), k2=5 to 20mm (preferably, for example, 7 to 15 mm), k3=20 to 35mm (preferably, for example, 12 to 25 mm), k4a=15 to 50mm (preferably, for example, 20 to 30 mm), k4b=22.5 to 37.5mm (half of the width of the mouse), k4c1=9 to 30mm (preferably, for example, 12 to 20 mm), k4c2=15 to 80mm (preferably, 40 to 75 mm), k4d1=k4D 2=7 to 20mm (preferably, for example, 15 to 20 mm), k3=20 to 35mm (preferably, for example, 12 to 20 mm), k3=20 to 35mm (preferably, 12 to 35 mm), k3=20 mm (preferably, for example, 12 to 25 mm), k3 to 80mm (preferably, 60 to 60 mm), and preferably, 60 to 60 mm (preferably, 60 mm).

It is obvious that the above dimensions are not limited to the above examples, and various variations may be made depending on the dimensions of the mouse 1, the housing 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, setting K1 and K2 to the above-described dimensions, and setting the dimensions of K4A, K6 and K7, in particular, K7 to be as large as possible, even when the mouse 1 is subjected to the sterilization treatment by the high-temperature and high-pressure steam in the autoclave apparatus, since the distances K1, K2, and K7 are ensured, in particular, the influence of the high-temperature and high-pressure steam and the influence of the moisture on the electronic circuit component 5 can be prevented, and the electronic circuit component 5 and the like can be protected from damage or malfunction due to the high-temperature and high-pressure steam.

The distances K1 to K7 are important elements for obtaining the operational effects of the present invention (protection of the electronic circuit component 5, etc.) in addition to the respective dimensions described above, and the ratio of the distances K1 to K7 to each other. As a preferable ratio, the inventors have confirmed that K1 to K7 are considered to be a relationship of K1> K2, K1≡K3 or less. Based on this ratio, when the ratio of the distances K1 to K5 is expressed by a number, K1: k2: k3: K4A: K4B: k5 =3: 2:4:5:5:11 to 14 as K4A: k6: ratio of K7, 2:1: the ratio of 6 is considered to be a preferable ratio.

By setting the ratio of the distances K1 to K7 to the above ratio, even when the mouse 1 is subjected to the sterilization treatment by the high-temperature and high-pressure steam in the autoclave apparatus, the distances K1 and K2 are ensured in particular, so that the influence of the high-temperature and high-pressure steam and the moisture can be prevented from being transmitted to the electronic circuit component 5, and the electronic circuit component 5 can be protected from damage or failure due to the high-temperature and high-pressure steam.

Moreover, among the above-mentioned ratios, particularly the ratio of the entire height of the mouse 1 to the distance K1 is very important for the present invention. For example, when the overall height of the mouse 1 is 40mm, it is very advantageous to set the dimensions of the distances K1 to K7 and the ratio between them to the optimum ratio, so that the sterilization treatment by the steam at high temperature and high pressure can be carried out even when the mouse 1 is exposed to severe treatment conditions such as autoclave treatment.

As described above, in the mouse 1 according to embodiment 1, the electronic circuit component 5 to be protected from high heat and the like can be secured at the distances K1 to K7 from any direction, and the arrangement position is selected so that heat and the like from the outside of the mouse 1 from any direction, particularly 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 the arrangement position of embodiment 1, and may be arbitrary and selected in consideration of the necessary heat resistance and the like.

With the above configuration, in the mouse 1 according to embodiment 1, heat from the outside and the like are not easily transferred to the electronic circuit component 5 and the like of the substrate 10 during the sterilization process. As a result, 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 and water vapor, and can withstand the sterilization treatment by the high temperature and high pressure water vapor in the autoclave apparatus and the like.

In embodiment 1, the opening R1 of the bottom 2B of the case is made a minimum opening in order to minimize heat and water (steam) penetration during sterilization and to facilitate waterproofing and pressure resistance. Since the optical fiber 6f is used as the transmission unit 6, the mouse 1 can reduce the area of the opening R1 where the lens 4 is provided. The area and volume of the opening R1 and the lens 4 are set to be sufficiently large enough to introduce the image light, and are kept to a minimum. The width H1 represents 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 penetrate into the gap of the moisture. Thus, the opening R1 can improve heat resistance, water resistance, pressure resistance, and the like of the sterilization process. In addition, if the occupied area of the opening R1 is reduced, other components can be disposed more, and functions and the like can be improved.

In fig. 2, the substrate 10 and other parts are disposed in the inner space of the housing 2 by any mechanism at the illustrated positions. The substrate 10 may be physically connected to the case 2, or may be housed only in the case 2 without such connection, and the position thereof may be changed. In the configuration example of fig. 2, the substrate 10 is not connected to the case 2. The substrate 10 may be mounted above the object disposed in the first space SP1, as will be described later.

In the mouse 1, the lens 4 is disposed in a space (the first space portion SP 1) which is located downward by a distance K2 from the lower surface of the substrate 10 located at the lower side in the Z direction, and conversely, the electronic circuit component 5 and the like are disposed on the upper surface of the substrate 10 located at 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 so as to pass through the side surface of the substrate 10 and wrap around. Thus, the opening R1 and the lens 4 of the case bottom 2B are horizontally spaced apart from the electronic circuit component 5 by the distance K7, and are disposed vertically by the distances K1 or K2, that is, are sufficiently spaced apart from each other in terms of thermodynamics, 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 the first space portion SP1, not only the conveying portion 6 but also other members may be disposed. In this space, in particular, a wireless charging unit can be disposed as the power supply unit 8, and therefore, in this case, the wireless charging performance can be easily improved. In the case of the wireless communication system or the wireless charging system, a wired cable and a mechanism including an opening therefor are not required, and thus the sterilization process is more advantageous.

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

The type having heat insulation property or the like of the optical fiber 6f and other wirings (for example, the wiring 3c of the button 3, the wiring 7c of the light source unit 7, the wiring 8c of the power source unit 8 and the like) may be applied, 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 in a plan view in a horizontal plane (X-Y plane). Fig. 3 shows a configuration, in particular, at a position where the substrate 10 is present in the Z direction. In this example, the housing 2 and the like have a substantially bilateral symmetry. One end of an optical fiber 6f serving as a transmission unit 6 is connected to the lens 4 of the opening R1 disposed at a distance K6 from the end side surface of the left side (fig. 2 and 3) of the housing upper portion 2A of the mouse 1. The mouse 1 of embodiment 1 has a wireless communication function, but may have a wired communication function. In this case, an opening through which the cable passes is required in the case 2, and countermeasures 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 of embodiment 1. In this example, the transfer section 6 is a wiring line passing through the space on the front side in the housing 2 and the second space section SP2, but may be another wiring line described later. As a configuration of the 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 front space 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 on the upper side of the substrate 10 in the second space portion SP2, and reaches the rear electronic circuit component 5 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 constituted by, for example, joining a housing upper portion 2A and a housing bottom portion 2B. In the Z direction, a position SZ1 represents an example of a joint position of the housing upper portion 2A and the housing bottom portion 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 housing 2, that is, may be a curved joint surface. The case 2 is not limited to this, and may be composed of three or more parts. In addition, a heat insulating material or a sealing material is provided in the vicinity of the joint position between the housing upper part 2A and the housing bottom part 2B for heat insulation and water resistance, thereby improving heat insulation and water resistance. The case 2 is made of a material having predetermined properties (first properties) including heat resistance, heat insulation, water resistance, water repellency, pressure resistance, and the like, as will be described later.

[1-5: Image sensor

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

In (a), the electronic circuit component 5 is connected to the upper surface of the substrate 10 so as to be mounted on the upper side in the Z direction. An image sensor 15 is mounted on the upper surface of the electronic circuit part 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 the image light from the optical fiber 6f and converts the image light into data of pixel values of the respective pixels. The electronic circuit unit 5 receives the image signal from the image sensor 15, and performs the above calculation.

In (B), the electronic circuit components 5 are connected to the lower surface of the substrate 10 so as to be mounted on the upper and lower sides in the Z direction. An image sensor 15 is connected to the lower surface (upper surface when viewed from the electronic circuit part 5) of the electronic circuit part 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 R2 provided in a part of the substrate 10. The electronic circuit component 5 is integrally mounted 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 method of the transmission unit 6 and the electronic circuit member 5 or the image sensor 15 is not limited to these, and may be any. The electronic circuit unit 5 and the image sensor 15 may be integrally formed.

[ Description of an example of applying the mouse of the present embodiment to the sterilization treatment in an autoclave ]

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

In the medical setting, infection countermeasures based on standard preventive strategies are important. Standard preventive strategies include cleaning, disinfecting, sterilizing medical instruments. Cleaning refers to removing foreign matter from an object. Disinfection 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, disinfecting, sterilizing required varies depending on the object. By the cleaning and disinfection, bacteria and the like can be killed to some extent, but not completely. Since the medical mouse is operated by hand, a countermeasure to a corresponding extent is required. In the prior art, only the surface of the mouse is sterilized, but the sterilization cannot be performed.

Sterilization includes autoclave sterilization, gas sterilization, chemical sterilization, etc. The autoclave has high sterilization operability and no residual toxicity, and is therefore the most popular method that is the safest and most practical method for subjecting an object to sterilization treatment conditions. The pre-vacuum method in the autoclave apparatus of class B is a method of forming a vacuum state in the internal space Y2 during the sterilization and drying steps, and is effective for objects of all shapes. The procedure in the sterilization example is as follows. The flow includes a step YS1 of preparing cleaning and removing attachments, a step YS2 of cleaning, a step YS3 of drying, a step YS4 of packaging, and a step YS5 of sterilizing in this order. The washing step YS2 may be performed by, for example, dipping with a detergent. The packaging step YS4 is a step of packaging the mouse 1, which is an object to be sterilized, with a sterilization bag.

When the autoclave sterilization treatment of the class B is performed by using the pre-vacuum type autoclave apparatus Y1, the sterilization step YS5 further includes the following steps. The step YS5 includes a vacuum vapor supply step YS11, a pressurizing and heating step YS12, a sterilizing step YS13, a depressurizing and vapor discharging step YS14, and a drying step YS15. The vacuum vapor supply step YS11 is a step of extracting air from the internal space Y2 and filling the whole with saturated vapor. The pressurizing and heating step YS12 is a step of pressurizing and heating the internal space Y2. The sterilization process YS13 is the following process: as a conditional example, the temperature in the water vapor in the internal space Y2 is maintained at a predetermined temperature in the range of 121 to 137 ℃, and the pressure is maintained at a predetermined pressure in the range of 2 to 2.2 air pressure (2.1 air pressure in the example of fig. 25), and the treatment is performed for a predetermined time period of, for example, 20 minutes or more. The depressurizing and vapor discharging step YS14 is a step of depressurizing the internal space Y2 and discharging vapor.

The mouse 1, which is the object Y3 subjected to sterilization, is required to have a performance capable of withstanding high-temperature and high-pressure steam and the like in the sterilization step YS13 and the drying step YS15, and the mouse 1 of the present embodiment sufficiently has this performance. By the flow including the sterilization step YS5, the bacteria adhering to the object Y3, that is, the mouse are killed. After the treatment, the object Y3 is taken out from the autoclave apparatus Y1 and stored.

For steam at a predetermined temperature and pressure during sterilization, a case and electronic circuit components of a general computer input and operating mouse are damaged and deteriorated, and cannot withstand the steam. In contrast, the mouse 1 according to embodiment 1 and the like is designed to be heat-resistant, heat-insulating, waterproof, pressure-resistant, and the like, for a structure including a housing and electronic circuit components, so as to be able to withstand water vapor at a predetermined temperature and pressure during sterilization. The mouse 1 according to embodiment 1 uses as few members as possible that are made of a material that does not generate heat (for example, general plastic), and when used, measures such as heat insulating materials are used in combination. The mouse of embodiment 1 has properties such as heat insulating property, heat resistance, water resistance, pressure resistance, etc. at predetermined levels, and can withstand any of the above-mentioned cleaning, disinfection, sterilization, etc. The structure of the mouse 1 of embodiment 1 may have a performance that can withstand a lower degree of sterilization treatment, but more preferably has a performance that can withstand a sterilization treatment of an autoclave of class B.

[1-6: Effect and the like

(A) As described above, the mouse 1 according to embodiment 1 is configured to: the lens 4 at the bottom 2B of the case is separated from the electronic circuit member 5 of the substrate 10 and the image sensor 15 by the distances K1 and K2 in the vertical direction and also separated from each other by the distance K7 in the horizontal direction, so that heat or the like penetrating into the mouse 1 from the opening R1 and the lens 4 is prevented from reaching the electronic circuit member 5 and the image sensor 15 to the maximum extent. Accordingly, the mouse 1 can withstand the sterilization treatment by the high-temperature and high-pressure steam even under such severe treatment conditions as exposure to the autoclave treatment. As a result, the environment in which the computer system including the mouse 1 is used can be expanded to a medical field or the like. In particular, in a medical field, a system including a sterilized mouse is used, so that advanced diagnosis and treatment, surgery, and the like are possible.

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

(C) In embodiment 1, the planar shape of the substrate 10 is formed into a substantially elliptical shape similar to the shape of the inner surface of the structural surface of the frame 2, that is, a substantially elliptical shape, as shown in fig. 3, so that the distance from the inner surface of the structural surface of the frame 1 is as uniform and large as possible over the entire circumference of the substrate 10, whereby heat entering from the outside through the structural surface of the frame 2 can be prevented as much as possible, and the area of the substrate 10 is reduced as much as possible, whereby heat accumulated in the substrate 10 is not conducted to the electronic circuit component 5 or the like by heat conduction. As a result, even if the planar shape of the substrate 10 is a carefully designed surface, accumulation of heat to 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.

(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 the sterilization treatment by the high-temperature and high-pressure steam in the autoclave apparatus, the distances K1 and K2 are ensured in particular, so that the influence of the high-temperature, high-pressure, and moisture due to the high-temperature and high-pressure steam can be prevented from being transmitted to the electronic circuit component 5, and the electronic circuit component 5 can be protected from damage or failure due to the high-temperature, high-pressure, and steam.

(E) In addition, according to the mouse of embodiment 1, the lens 4 at the bottom 2B of the case is arranged to be spaced apart from the electronic circuit component 5 and the image sensor 15 of the substrate 10 via the transmission unit 6, so that 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 heat and water from the outside.

[1-7: Modification 1]

Fig. 6 shows a mouse 1 according to a modification (modification 1) of embodiment 1. (A) shows a longitudinal section and (B) shows a planar structure. The mouse 1 of modification 1 has the following structure: (a) no light source unit 7 (or a lighting device such as an LED) is provided; (b) a plurality of electronic circuit components 5 on a substrate 10; (c) the power supply section 8 is divided into a secondary battery 8A and a wireless charging section 8B; (d) the button 3 is of the type with a lever; and (e) a substrate support portion in the case 2. In fig. 6 and the following drawings, the middle part of the conveying unit 6 may be omitted for clarity of illustration.

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

(B) The substrate 10 has a plurality of electronic circuit components 5 as follows. In this example, an electronic circuit component 5a and an 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 in the housing 2, for example, at a position near the center. On the other hand, as seen in fig. 6, the opening R1 and the lens 4 are disposed near the left end of the case bottom 2B, and the electronic circuit member 5 is disposed apart from the opening R1 and the lens 4 in both the horizontal direction and the up-down direction. The electronic circuit part 5a is a part of a controller constituting a 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 unit 5a calculates the state of the mouse 1 by processing the image signal from the image sensor 15, and controls the wireless communication function of the electronic circuit unit 5b by processing the input of the button 3 to perform communication with the outside. The arrangement position of each electronic circuit component 5 may be selected appropriately in consideration of heat resistance and the like. The wireless communication circuit of the electronic circuit part 5b transmits data concerning the state of the mouse 1 to an external computer or the like. The present invention is not limited to the wireless communication system, and may be applied to infrared systems, bluetooth (registered trademark), and the like.

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

(C) The power supply unit 8 is configured as a secondary battery 8A and a wireless charging unit 8B as follows. The wireless charging unit 8B is configured by a circuit such as a power receiving coil, receives power supply from a wireless power supply unit (power transmitting coil or the like) such as an external mouse pad by electromagnetic induction or the like, and charges the secondary battery 8A with the power supply power through the wiring 8 c. In this example, the wireless charging unit 8B is disposed at a position rearward of the upper surface of the case bottom 2B, and the secondary battery 8A is disposed at a position rearward of the upper surface of the substrate 10. In the case where the secondary battery 8A is a member that does not generate heat, it is disposed at a position away from the case bottom 2B upward, as in the case of the electronic circuit member 5. The wireless charging portion 8B can be disposed in the first space portion SP1 between the case bottom 2B and the substrate 10, and therefore a wide area is easily ensured, that is, wireless power supply efficiency is easily improved.

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 2B, or a type of power supply unit that has contact terminals exposed to the outer surface of the case bottom 2B. In this case, measures such as providing a cover having heat insulation and water resistance are taken 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 is preferably a smooth shape with respect to the outer surface of the housing 2. The cleaning agent is smooth and has contamination resistance and easy cleaning.

(D) The structure of the push button 3 is of the type with a lever, in other words a physical switch, in the manner described below. In a forward position of the outer surface of the housing upper part 2A, the push button 3 is arranged to have a continuous curved surface with respect to the outer surface of the housing upper part 2A. The button 3 is made of, for example, a hard resin, and is displaced in the up-down direction by a pressing operation of a user. On the underside of the push button 3, a rod 3d is fixed in an extending manner. The lever 3d is displaced in the up-down direction with the displacement of the push button 3. At a front position of the upper surface of the substrate 10, a switch 3e is provided so as to match the position of the lever 3 d. Is in physical contact with the switch 3e corresponding to the displacement of the lever 3d in the downward direction. Thereby, the circuit within the switch 3e is shifted from the off state to the on state. The switch 3e is connected to the electronic circuit part 5a through a circuit of the substrate 10. The controller of the electronic circuit unit 5a inputs the on/off signal from the switch 3e to perform processing, and grasps the operation state of the button 3. Further, countermeasures such as heat insulation and the like described later may be implemented in the lever 3d and the switch 3e. The structure of the button 3 is arbitrary, and the countermeasure against heat and water resistance can be implemented in the vicinity of the button 3 in any manner without limitation.

(E) The structure having the substrate support portion in the case 2 is as follows. In this example, the support portion 2C is provided so as to extend upward from a part of the housing bottom 2A. (B) In the above, the support portions 2C are provided at four portions of the bottom 2B of the case, corresponding to four portions of the substrate 10. The lower end of the support portion 2C is supported by the housing bottom 2B, and the substrate 10 is supported at the upper end. Thus, the substrate 10 is disposed at a predetermined position in the case 2, that is, a position separated from the surface of the case 2 as much as possible. The substrate 10 may be fixed to the support portion 2C or may be placed only on the support portion 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 (fig. 6) are shown. The support portion 2Cb is provided so as to extend horizontally from a side surface portion of the housing upper portion 2A, and supports the substrate 10 at a front end. The support portion 2Cc is provided so as to extend downward from the upper surface portion of the housing upper portion 2A, and fixes the substrate 10 at the front end. The support portion 2C is preferably made of a heat insulating material, or countermeasures such as heat insulation, which will be described later, may be taken in the support portion 2C.

As another configuration example, the case 2 may be provided with a pressure adjustment mechanism. Since high temperature and high pressure are applied to the housing 2 during the sterilization process, it is more preferable if a pressure adjusting mechanism is provided for pressure adjustment in the housing 2. The pressure adjusting mechanism may be a pressure adjusting valve or the like. A pressure adjustment mechanism may be attached to the button 4 and the opening R1.

< 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, which are different from those of embodiment 1. The mouse of embodiment 2 has a heat-insulating and waterproof structure as compared with the structure of the mouse of embodiment 1.

A configuration example of the mouse of embodiment 2 shown in fig. 7 and the like is a configuration in which a multi-layered heat insulating structure (in other words, a sealed heat insulating structure) is added to the mouse of embodiment 1 of fig. 2 and the like as a basic and common structure. The insulation construction has multiple layers or multiple insulation materials. The mouse has a multi-layered heat insulating structure corresponding to the degree of heat resistance and the like required according to the use environment (environmental change corresponding to the degree of sterilization and disinfection performed at the medical site of use). In addition, when the required heat resistance and the like can be lower, modifications may be made to omit a part of the heat insulating layer and provide only a part of the heat insulating layer.

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

[2-1: Mouse, wiring example 1]

Fig. 7 (a) shows a vertical section of the mouse 1 as the mouse of 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 insulating structure including the plurality of heat insulating layers generally includes a first heat insulating layer 21, a second heat insulating layer 22, a third heat insulating layer 23, a fourth heat insulating layer 24, and a fifth heat insulating layer 25. The properties of the respective heat insulating layers may be the same or different.

(1) The first insulating layer 21 is a case insulating material, and is disposed so as to be in contact with the surface (outer surface or inner surface) of the case 2. In this case, in particular, the first heat insulating layer 21 is provided in contact with the inner surface of the housing 2. When the first heat insulating layer 21 is provided on the outer surface of the case 2, it may be a cover, a coating, or the like having heat insulating properties. The casing 2 may be constituted by multiple layers such as an outer casing and an inner casing, which will be described later, and in this case, the first heat insulating layer 21 may be constituted by one of the outer casing and the inner casing, or may be a layer interposed between the outer casing and the inner casing. Alternatively, the coating and the material may be disposed between the outer surface and the inner surface of the outer case, the outer surface and the inner surface of the inner case, and the outer case and the inner case, respectively, so as to have an 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. The third space SP3 is formed in the second heat insulating layer 22. The second heat insulating layer 22 is disposed further inside than the case 2 and the first heat insulating layer 21. The second heat insulating layer 22 is not connected to the first heat insulating layer 21 and has a space therebetween.

(3) The third heat insulating layer 23 is an independent component heat insulating material, and is disposed so as to cover the electronic circuit component 5, the secondary battery 8A, the wireless charging unit 8B, and other independent components. The third heat insulating layer 23 sets a component that is not subjected to heat generation 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 in the wireless charging unit 8B may be omitted. The third heat insulating layer 23 may be provided so as to surround the whole of the independent 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 may also realize an important function of supporting or fixing the substrate 10 when disposed on the lower side of the substrate 10. In the case where the electronic circuit component 5 and other components have sealing properties and heat insulation properties (for example, a package component), the third heat insulating layer 23 may be omitted.

(4) The fourth heat insulating layer 24 is a wiring heat insulating material, 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 contact with the first heat insulating layer 21 and the second heat insulating layer 22 in the first space portion SP1 between the case bottom 2B and the substrate 10 and the second heat insulating layer 22, for example. In particular, the fifth heat insulating layer 25 is disposed centering on a lower position in the vicinity of the center of the electronic circuit component 5, and can enhance the heat insulating effect on the electronic circuit component 5. The fifth heat insulating layer 25 may be disposed so as to cover the transfer section 6, the fourth heat insulating layer 24 thereof, and the like. Then, the second heat insulating layer 22 including the substrate 10 is placed and supported on the upper side of the fifth heat insulating layer 25. Thereby, the substrate 10 and the like are positioned. That is, the fifth heat insulating 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 the 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 passes through, for example, the opening Q1 of a part of the upper surface side of the second heat insulating layer 22, enters the third space SP3 in the second heat insulating layer 22, and is connected to the electronic circuit component 5 and the like. The wiring 3c from the button 3 enters the third space portion 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 portion SP3 through the opening Q3 of a part of the second heat insulating layer 22, and is connected to the secondary battery 8A. The wiring 7c from the light source 7 enters the third space SP3 through the opening Q4 of a part of the second heat insulating layer 22, and is connected to the substrate 10. The fourth heat insulating layer 24 may be omitted from the second heat insulating layer 22. The heat insulation and the like can be improved by providing sealing materials and the like in the openings Q1, Q2, Q3, Q4, respectively. From the viewpoint of heat insulation, the number of openings such as the opening Q1 in the second heat insulating layer 22 is preferably reduced as much as possible. Thus, the plurality of openings may be integrated into one opening.

In the first space portion SP1, the light source portion 7 and the wireless charging portion 8B are more preferably provided on the upper surface of the first insulating layer 21, but may be provided on the upper surface of the case bottom 2B in a case where heat resistance is high or the like. Various members and heat insulating layers can be disposed in the region left free in the first space portion SP1 as needed. This is advantageous in terms of the high-level and heat-insulating properties of the mouse function.

In this example, the transfer section 6 is a wiring that is wound around the center position of the electronic circuit component 5 from the front side, and no notch or through hole is provided in the substrate 10. In the case where the wiring is to be shortened, a region where the notch or the through hole is provided in the substrate 10 may be a desired wiring path through the region.

Further, heat-insulating 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 in fig. 7 may be heat-insulating coated. This reduces heat conduction into the substrate 10, and reduces the influence on components such as the electronic circuit component 5 caused by heat conduction through the substrate 10. In addition, the amount of the heat insulating material to be provided can be reduced by the amount of the heat insulating coating of the substrate 10.

(6) The electronic circuit component 5 is disposed in the center of the internal space of the case 2

In embodiment 2, the electronic circuit component 5 is disposed in the inner space of the housing 2 at a position separated from the inner surface of the outer housing 2 structural surface in any direction, for example, at a position near the center of the inner space. In embodiment 2, as in embodiment 1, the opening R1 of the mounting lens 4 is provided near the left end of the case bottom 2B (see fig. 7, etc.). That is, even in the mouse 1 of embodiment 2, the arrangement positions of the electronic circuit component 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 case 2 so as to be separated from the entire surface of the case 2 as much as possible.

This can improve the degree of freedom in the arrangement of 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 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 the sterilization process, the performance of heat and water, and the distance from the housing 2. This improves the heat resistance, water resistance, pressure resistance, and the like of the mouse 1, and can realize the performance of withstanding 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 substrate 10 and the electronic circuit member 5 are positioned at substantially the center of the inner space of the housing 2 of the mouse 1 in all directions of the vertical direction (Z direction) and the long side direction (Y direction) and the short side direction (X direction) of the housing 2 of the mouse 1 by spacing the distance K4A from the lower side surface of the housing 2A to the long side direction of the housing 2 in the Y direction and spacing the center of the electronic circuit member 5 from the outer surface of the side surface of the housing 2 in the X direction orthogonal to the Y direction, respectively. That is, in particular, the electronic circuit part 5 is arranged 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 positions separated from the electronic circuit component 5, that is, at positions near the left end of the housing bottom 2B, which is the front side of the mouse 1, and are separated from the electronic circuit component 5 disposed on the opposite side thereof in the horizontal direction and the vertical direction. Therefore, even if the mouse 1 is exposed to high-temperature and high-pressure steam from the surrounding area by the autoclave treatment, not only the opening R1 and the lens 4 but also the influence of the high-temperature and high-pressure steam from any direction can be eliminated, and the occurrence of damage and failure can be prevented.

By positioning at least the electronic circuit member 5 and the substrate 10 in 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, it is possible to ensure that the electronic circuit member 5 and the substrate 10 are kept at a sufficient distance from the inner surface of the structural surface of the housing 2, and it is possible to prevent occurrence of damage or failure by eliminating the influence of high temperature, high pressure, water vapor or the like from any direction even when subjected to sterilization treatment by high temperature, high pressure water vapor in the autoclave apparatus, for example, due to the thermal insulation effect achieved by air or an insulating material described later.

[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 insulating structure. The respective layers are described in the order from the outside to the inside. The term "insulation (thermal insulation)" refers to a general term for preventing heat transfer. The case 2 and the heat insulating layers of the mouse 1 have resistance to temperature and pressure changes during autoclave treatment and strength. Fig. 8 shows a case where the transfer unit 6 is wired through 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 water vapor resistance), water resistance (in other words, sealability), pressure resistance, durability (resistance to the number of repeated use, temperature change, and the like), and the like. The case 2 preferably has contamination resistance and easy cleaning properties by a shape such as a curved surface. In addition, the housing 2 has chemical resistance to water, disinfectant medicines, and the like. The housing 2 is made of a hard resin such as super engineering plastic. Super engineering plastics are engineering plastics having strength, heat resistance, water resistance, etc. The case 2 may be made of a material mixed with heat insulating particles. The housing 2 may be made of a reinforced resin material including a glass fiber, a carbon fiber, and the like. The case 2 and each heat insulating layer are not limited to one layer, and may be formed of a plurality of layers.

2. The first heat insulating layer 21 has heat resistance, heat insulation, durability, and other properties (second properties). The first heat insulating layer may be provided on the whole of the casing 2 or may be provided in a part thereof. For example, the first heat insulating layer 21 may be provided only in the bottom case 2B. The first insulating layer 21 may be a coating on the casing 2.

3. A space having air is provided between the first heat insulating layer 21 and the second heat insulating layer 22 including the substrate 10, thereby having heat insulating properties. The space includes a first space portion SP1 and a second space portion SP2. A heat insulating material, a heat absorbing material, a filling material, and the like may be additionally disposed in the space as described below.

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

5. The second heat insulating layer 22 has, for example, the same second property. The second heat insulating layer 22 may be further formed of a plurality of layers. The second heat insulating layer 22 has a third space SP3 therein. The third space portion SP3 is a space of air, but as a modification, a space filled with Ar gas, a space in a near vacuum state, a space filled with a heat insulating material, or the like may be used. In this case, the second heat insulating layer 22 has sealability. The substrate 10 and the second heat insulating layer 22 are more preferably configured to have a space not in contact with the case 2, and are more preferably configured to have thermal conductivity.

6. The third heat insulating layer 23 in the second heat insulating layer 22 has, for example, the same second property and further has an insulating property. The surfaces of the substrate 10 and the mounting members such as the electronic circuit member 5 may be heat-insulating coated with the same properties as the third heat insulating layer 23.

In fig. 8, an example of the direction of heat applied from the outside of the mouse 1 is shown by an arrow at the time of sterilization treatment in the autoclave device Y1 of fig. 25. Here, this direction is shown focusing on the electronic circuit component 5. The direction of heat intrusion is omnidirectional, but here only eight directions are shown. The mouse 1 according to embodiment 2 uses the transmission unit 6 to dispose the electronic circuit component 5 and the like in a position near the center in the housing 2. Therefore, in the sterilization process, heat from the outside is conducted from all directions on the surface of the case 2 to the electronic circuit component 5, and the thermodynamic distance is large, so that heat conduction is difficult. In addition, since a plurality of heat insulating layers are provided in each direction, heat conduction to the electronic circuit part 5 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 heat insulating layers are provided, heat conduction from the opening R1 and the lens 4 can be prevented. Before the heat reaches the electronic circuit component 5, it can be insulated by the heat insulating layers, and control of the temperature distribution of the internal space of the case 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 case 2 and the protection target member, the placement position may be selected so as to further shorten the distance between the case 2 and the protection target member 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. The heat insulating layer is not limited to the form of providing the heat insulating layer in the omnidirectional region such as the surface of the case 2, but may be provided in a region where the heat insulating property is desired to be improved. For example, each heat insulating layer may be provided only in the region corresponding to the bottom 2B of the case.

[2-3: Connection of lens to transfer section

Fig. 9 is a schematic diagram showing an example of a connection structure between the lens 4 of the opening R1 of the case bottom 2B and the optical fiber 6f as the transmission unit 6 in the mouse 1 according to embodiment 2. (A) shows a cross section and (B) shows a planar configuration. A first insulating 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 in (B), the lens 4, the optical fiber 6f, and the like have, for example, axisymmetric shapes. The lens 4 preferably has properties such as heat resistance, water resistance, pressure resistance, durability, and temperature change without deformation, discoloration, or little deformation, discoloration, or the like.

A lens 4 is fixed to the bottom 2B of the case. The flange portion 4g of the lens 4 is a portion for position fixing and sealing. The curved surface of the lens 4 (here, although being 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 case bottom 2B in the opening R1 has a shape with as few irregularities as possible for contamination resistance and easy cleaning. Or a cover having light transmittance, heat resistance, water resistance, etc. is disposed in the space so that the cover is smooth with respect to the lower surface of the case bottom 2B. Alternatively, the lens 4 or a part of the cover may have a curved shape with respect to the main surface of the case bottom B and protrude downward. One end of an 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. At the time of manufacture, the case bottom 2B is formed by injection molding, for example, whereby the respective members may be fixed. An adhesive material, 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 providing the first heat insulating layer 21, the fourth heat insulating layer 24, the fifth heat insulating layer 25, and the like with adhesiveness. The adhesive material and the sealing material are required 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 case bottom 2B, but the present invention is not limited thereto and may be arbitrarily used. As another configuration example, in the case where the housing 2 is constituted by an outer housing and an inner housing, the lens 4 may be fixed between the outer housing and the inner housing. In the case where there is the light source wiring 7d from the light source 7, for example, one end of the light source wiring 7d (schematically shown by a broken line) using an optical fiber may be optically connected to the lens 4 in the case bottom 2B.

[2-4: Effect and the like

(A) As described above, according to the mouse of embodiment 2, by providing the multilayer heat insulating structure, heat insulating property, water resistance, and the like can be further improved than those of embodiment 1. In addition, with this configuration, the autoclave sterilization treatment of class B can also be received (fig. 25). In the medical field, the sterilized mouse can be used for surgery and the like. In the case where a member having heat resistance or the like is used for all the constituent members inside the case 2, the heat insulating structure inside the case 2 may be omitted or omitted, and the structure of embodiment 1 may be employed.

(B) According to the mouse of embodiment 2, since the electronic circuit member 5 and the substrate 10 are positioned at least in 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 between the electronic circuit member 5 and the substrate 10 and the inner surface of the structural surface of the housing 2 can be ensured, and the heat insulating effect by air or an insulating material can be obtained, even if the sterilization treatment is performed by high-temperature and high-pressure steam inside the autoclave apparatus, for example, the influence of high-temperature, high-pressure, steam and the like from any direction can be eliminated, and the occurrence of damage and failure can be prevented.

[2-5: Modification 2]

Fig. 10 shows a structure of a mouse 1 according to modification 2 of the mouse of embodiment 2. (A) shows a longitudinal section and (B) shows a planar structure. In modification 2, the structure of modification 1 of fig. 6 is used as a basic and common base, and a heat insulating structure is added. A first heat insulating layer 21 is provided on the inner surface of the housing 2. The rod 3d of the push button 3 and the support portion 2C of the case bottom 2B penetrate a part of the first heat insulating layer 21 and the second heat insulating layer 22. Further, the second heat insulating layer 22 may be interposed between the rod 3d and the switch 3 e. A substrate 10 having a plurality of electronic circuit components 5 (5 a, 5 b), a secondary battery 8A, and a 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. 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.

As another modification, a 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 wire communication cable 1001 has heat insulation, sealing, and the like in the opening 1002. In addition, the power supply unit 8 may be provided with a terminal or a power cable so as to extend outside the housing 2. In this case, the terminal, the power cable, and the opening therefor have heat insulation, sealing properties, and the like. In this case, no battery is required in the housing 2. Further, it is preferable that the metal part of the member such as a connector, not shown, related to the cable 1001, the power cable, and the like has rust resistance.

As another modification, a region such as a cutout 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 section 6 may be routed through the region.

[2-6: Modification 3]

Fig. 11 shows a vertical section of a mouse 1 according to modification 3 of the mouse of 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 section 7 at a front position. The light source unit 7 is controlled by the electronic circuit member 5 through the circuit of the substrate 10. The light source portion wiring 7d from the light source portion 7 extends to the first space portion SP1 through, for example, an opening portion of a part of the second heat insulating layer 22, and is connected to the lens 4. The light source section wiring 7d is covered with a fourth heat insulating layer 24 using, for example, an optical fiber. The light source section wiring 7d and the optical fiber 6f of the transmission section 6 may be gathered by the fourth heat insulating layer 24 and the fifth heat insulating layer 25.

In modification 3, the electronic circuit member 5, the secondary battery 8A, and the wireless charging section 8B on the case bottom 2B in the third space SP3 in the second heat insulating layer 22 are substantially entirely surrounded by the third heat insulating layer 23. In modification 3, the independent components such as the secondary battery 8A are 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 independent components such as the secondary battery 8A and the upper surface of the substrate 10. The wireless charging unit 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 can be achieved at least in part.

[2-7: Modification 4]

Fig. 12 shows a structure of a mouse 1 according to modification 4 of the mouse of embodiment 2. In modification 4, a configuration example is shown in which a light introduction portion such as a slope portion is provided in the case 2 without providing the light source portion 7 (or the lighting device such as an LED). (A) shows a longitudinal section and (B) shows a transverse section. The case 2 is provided with a slope 1202 as a light introducing portion in a partial area 1201 as viewed from the side. The region 1201 is a left and right region which is close to the case bottom 2B in the Z direction and which is located in the X direction except for the opening R1 near the left end of fig. 12 (front side in the Y direction) of the case bottom 2B, and has a curved surface which is easy to hold by a hand, for example. By the shape of the housing 2, ambient illumination light easily enters the lens 4 of the opening R1 through the region 1201 between the mounting surface SF. Thus, even when the light source unit 7 is not provided, a large amount of indoor illumination light can be applied. This can prevent heat generation by the light source unit 7 in the housing 2, and can increase the usable time of the mouse.

In fig. 12, the transmission unit 6 and the like are not shown. In this configuration, the wiring of the transfer section 6 can be, for example, wiring in the front-rear direction described later. In this structure, a slope portion 1202 protruding from the bottom 2B of the case may be used, and the upper substrate 10 and the second heat insulating layer 22 of the slope portion 1202 may be placed or fixed. Even when 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 can be achieved at least in part.

[2-8: Wiring example 2]

Fig. 13 shows another wiring example of the transfer unit 6 as a modification of the mouse of embodiment 2. Fig. 13 shows a case where the front side wiring is provided as wiring example 2. (A) shows a longitudinal section and (B) shows a planar structure. The transmission unit 6 uses, for example, an optical fiber 6f. The optical fiber 6f is covered with the fourth heat insulating layer 24. The wiring path of the transfer section 6 is as follows. First, one end of the optical fiber 6f of the transmission section 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 2B. From this position, the optical fiber 6f extends upward in the Z direction in the first space portion SP1, and reaches 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 at the second space portion SP 2. Then, the other end of the optical fiber 6f enters the third space portion 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 the first space portion SP1, for example, a wireless charging portion 8B is disposed in a rear region. As a modification, a region such as a cutout 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 transfer section 6 may be routed through the region.

[2-9: Wiring example 3]

Fig. 14 shows a wiring example 3 of the transfer section 6 as a modification of the mouse of embodiment 2. In this example, the opening R1 and the lens 4 are not provided near the left end of fig. 14 of the case bottom 2B, but near the right end (rear side in the Y direction) which is the opposite side of the longitudinal direction, unlike the other embodiments. Thus, wiring example 3 is a case of rear side wiring. (A) shows a longitudinal section and (B) shows a planar structure. The wiring path of the transfer section 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 bottom 2B of the case in the first space SP1 to 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 at the second space portion SP 2. Then, the other end of the optical fiber 6f enters the third space portion 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 7 is disposed above the substrate 10, and is routed from there to the lens 4 (omitted).

[2-10: Positional relationship example (1)

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

In this configuration example, the wiring example of the transfer section 6 is a front-side wiring, and in particular, a wiring example of the transfer section is provided 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 routed in the second heat insulating layer 22, and connected to the image sensor 15 of the front-side electronic circuit component 5 on the substrate 10. The wiring is not limited to this wiring example, and may be provided via an area left in the housing 2. In addition, the fourth heat insulating layer 24 may be omitted from the second heat insulating layer 22. The secondary battery 8A may be disposed near the center of the substrate 10, or other components may be mounted.

In the modification of fig. 15, the lens 4 of the opening R1, the electronic circuit member 5, and the image sensor 15 are disposed at different positions in the horizontal direction, and therefore, even if heat or water enters the mouse 1 from the opening R1 and the lens 4 due to autoclave treatment or the like, it is possible to prevent the electronic circuit member 5 and the image sensor 15 from reaching.

[2-11: Positional relationship example (2)

Fig. 16 shows a modification of the mouse according to embodiment 2, which is another configuration example such as a positional relationship between the lens 4 and the electronic circuit member 5 and wiring. (A) shows a longitudinal section and (B) shows a planar structure. In this configuration example, the electronic circuit component 5 and the like are disposed near the center of the case 2 in a plan view on a horizontal plane, whereas the opening R1 and the lens 4 are disposed at positions different in the horizontal direction, that is, at positions on the front side of the case bottom 2B. Even in this configuration, the electronic circuit member 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.

The present modification is somewhat similar to embodiment 1, but mainly differs from embodiment 1 in that an electronic circuit component 5 or the like is disposed near the center of the case 2, whereas an opening R1 and a lens 4 are disposed at different positions spaced apart in the horizontal direction, that is, at a center position on the left side (fig. 16) of the case bottom 2B.

The following configuration is provided as an example of wiring of the transfer section 6. The optical fiber 6f of the transmission unit 6 extends upward from the position of the lens 4 of the opening R1 in the first space SP1, 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 extends toward the upper surface of the substrate 10 through a region 1601 such as a cutout or a through hole provided in the substrate 10. The other end of the optical fiber 6f extends rearward 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. In addition, even in the case of the substrate of the conventional mouse, there are some cases where a region such as a cutout or a through hole is provided. Such an area can be used for wiring of the transfer section 6. By disposing the lens 4 of the opening R1 at a position separated in the horizontal direction from the center portion of the case bottom 2B, it is possible to prevent heat and moisture entering the mouse 1 through the opening R1 and the lens 4 from reaching the electronic circuit component 5.

In (B), other wiring examples are generally shown with arrows. In the case where the substrate 10 is not notched in the region 1601, various wirings such as wiring examples EX1, EX2, EX3, and EX4 may be used. The wiring example EX1 is an example in which the lens 4 is temporarily extended from the front space and then passed through the second space SP 2. The wiring example EX2 is an example of passing through a position diagonally forward left in the side surface of the case 2. The wiring example EX3 is an example of the electronic circuit component 5 extending from the position of the lens 4 to the left of the case 2, extending rearward on the left side surface, extending upward to the upper side of the substrate 10, and extending to the center. The wiring example E43 is an example of the electronic circuit component 5 extending obliquely from the position of the lens 4 to the center, extending upward from the left surface of the case 2 to the upper side of the substrate 10.

[2-12: Wiring example 4]

Fig. 17 shows a wiring example 4 of the transfer section 6 as a modification of the mouse of embodiment 2. Wiring example 4 shows a case where the wiring is provided as a straight line penetrating upward. (A) shows a longitudinal section and (B) shows a planar structure. The wiring path of the transfer section 6 is as follows. The transfer section 6 first extends upward in the Z direction from the position of the lens 4 of the opening R1 near the center of the case bottom 2B in the first space SP1, and reaches the opening Q1 of the second heat insulating layer 22. In this example, the transfer section 6 is covered with a fifth heat insulating layer 25. In other words, the transfer section 6 penetrates the fifth heat insulating layer 25. The transfer section 6 enters the third space portion SP3 through the opening Q1, and penetrates upward in the region 1701 of the through-hole portion of the substrate 10. An upper electronic circuit member 5 having a through hole is mounted on the upper surface of the substrate 10, and an image sensor 15 is mounted on the lower surface side of the electronic circuit member 5, as in the third example of fig. 5.

In this modification, the transfer section 6 extends linearly upward only at the same position, and the wiring path length is shorter than in the above-described embodiment. The transmission unit 6 uses, for example, optical fibers 6f arranged in a straight line. The optical fiber 6f may be an inflexible optical fiber, or may be covered with a rigid cylindrical member or the fourth heat insulating layer 24. The transmission unit 6 is not limited to the linear optical fiber 6f, and may be made of other optical components. The transmission unit 6 may be constituted by a cylindrical light guide (for example, a lens barrel described later). The conveying section 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 needed, and advances upward, and is incident on the image sensor 15. The fourth heat insulating layer 24 may be provided on the light guide. The lens 4 of the case bottom 2B and the light guide may be integrally formed (the transmission unit 6 or the optical member).

In this modification, 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 in the first space portion SP 1. The fifth insulating layer 25 positions and fixes the second insulating layer 22 surrounding the substrate 10. The fifth heat insulating layer 25 is provided to have a larger area than the region 1701 of the through hole portion in plan view. Thereby, the heat insulation between the opening R1 and the electronic circuit component 5 is further improved.

Even in this modification, since the first heat insulating layer 21, the fifth heat insulating layer 25, and the second heat insulating layer 22 are provided between the lens 4 and the electronic circuit component 5 while the distance therebetween is sufficiently ensured, the effect of improving the heat insulating property and the like for protecting the electronic circuit component 5 is obtained. In addition, even when the substrate 10 has a through hole or the like, the heat insulation property is enhanced by the fifth heat insulation layer 25. Such a manner 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 which is deformed, for example, by being flexible at the time of manufacturing, and the second heat insulating layer 22 including the substrate 10 is positioned and fixed by being placed and pressed on top of the fifth heat insulating layer 25. The fifth heat insulating layer 25 is fixed and fixed by temperature control or the like, and thus the substrate 10 and the second heat insulating layer 22 are fixed and fixed. 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/or fixing the substrate 10 can be achieved.

[2-13: Wiring example 5]

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

The electronic circuit component 5 of the substrate 10 is disposed in the case 2, for example, at the lower surface of the substrate 10 in a position near the center. The distance K1B of the lower surface of the case bottom 2B from the upper surface of the electronic circuit part 5 may be selected in consideration of performance with respect to heat and the like. In this modification, the substrate 10 is disposed in the opposite direction, and therefore, the electronic circuit component 5 and the transfer section 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 section 6 and the like may be located below the substrate 10 in the second heat insulating layer 22.

In this modification, the light source unit 7 is mounted on the upper surface side (the entire middle lower surface side) of the substrate 10, for example, at a front position, and is housed in the second heat insulating layer 22 to be protected. The light source portion wiring 7d from the light source portion 7 extends to a position near the center in the third space portion SP3, for example, and extends outward through the opening Q1, and extends downward to be connected to the lens 4. The light source section wiring 7d may be an optical fiber. The two wirings (the transmission unit 6 and the light source unit wiring 7 d) are collected in the opening Q1, and heat insulation and the like are improved. In addition, when a plurality of wirings are collected, the fourth heat insulating layer 24, the fifth heat insulating layer 25, a binder, or the like may be used. In addition, in the case where the fifth heat insulating layer 25 is 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 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 the mouse of embodiment 3. First, the case 2 may be composed of a multi-layered case (in other words, a case portion) having two or more layers. In other words, a secondary housing portion (such as a case or a cover) may be provided on the outside or inside of the primary housing 2. The outer case may be an outer case, 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 case. In the configuration example of fig. 19, the housing 2 has a double structure of an outer housing 2S (outer housing portion) and an inner housing 2T (inner housing portion). In detail, the outer shell 2S has an outer shell upper portion 2A1 and an outer shell bottom portion 2B1, and the inner shell 2T has an inner shell upper portion 2A2 and an inner shell bottom portion 2B2. The housing upper part 2A has an outer housing upper part 2A1 and an inner housing upper part 2A2, and the housing bottom 2B has an outer housing bottom 2B1 and an inner housing bottom 2B2. The outer shell and the inner shell may be integrally formed or may be partially formed. For example, only the case bottom 2B may be formed of a double case. Each housing portion is made of a member having heat resistance, heat insulation, water resistance, water repellency, pressure resistance, and the like. The properties of the respective housing parts may also be made different. A sealing material or the like is disposed at the separated position SZ1 of the case 2 in the same manner as described above.

In the configuration example of fig. 19, the first heat insulating layer 21 is sandwiched and held between the outer shell 2S and the inner shell 2T of the housing 2 (a region between the inner surface sf2 of the outer shell 2S and the outer surface sf3 of the inner shell 2T). Thus, the first insulating layer 21 is stably held on the surface of the case 2, and peeling or the like is less likely to occur.

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

Further, a coating layer 26 for improving heat insulation, lubricity, and the like may be provided on the outer surface sf1 of the casing 2S (the casing upper portion 2A1 and the casing bottom portion 2B 1). In other words, the case 2S may be made of a 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 casing 2S. The heat absorbing material may be mixed into the outer and inner shells 2S and 2T of the case 2. As a result, heat from the outside can be absorbed in the housing 2 within an appropriate temperature range, and heat conduction into the housing 2 can be suppressed.

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

The inner space (the first space portion SP1 and the first space portion SP 2) of the case 2, the opening portion R1, and the like are sealed by the outer case 2S, the inner case 2T, the first heat insulating layer 21, the sealing material, and the like. Thus, heat generated during the autoclave treatment is less likely to propagate in the casing 2, and water vapor is less likely to intrude into the casing 2. The housing 2S may be formed of a cover made of, for example, silicone rubber. The inner shell 2T may also be constructed of, for example, super engineering plastic.

In this embodiment, the second heat insulating layer 22 is composed 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 of 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 the mouse of embodiment 4. In the mouse 1, first, as in the case described above, the housing 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 region left free is filled with a filling material 27 in the inner space of the case 2. The filler 27 may be a material having heat insulating properties and heat resistance, and may be embedded in the added heat insulating layer. The filling material 27 is made of, for example, an electrically insulating resin, and is cured by temperature control after being filled in a predetermined region at the time of manufacturing. 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 inner space of the case 2 as an example of the disposition of the filler 27 (corresponding filling region). For example, the filler 27b may be disposed in the first space portion SP1 as a whole, or the filler 27b may be disposed in a region where there is no component. Such a filler 27 may be provided as the fifth heat insulating layer 25. The heat resistance and the like against heat from the lower side of the substrate 10 are further improved by the filler 27a or the filler 27b. The filler 27a or the filler 27b may fix the second heat insulating layer 22 surrounding the substrate 10 to the upper side, or may fix the wiring of the transfer section 6.

The filler 27c may be disposed in the upper second space SP 2. The heat resistance to heat from the upper side of the substrate 10 and the like are further improved by the filling material 27c. In addition, the filler 27d may be disposed in the third space SP3 in the second heat insulating layer 22. The heat resistance of the substrate 10 is further improved by the filling material 27d. The filling material 27c and the like may be formed along the inner surface of the case 2. In addition, when the filling material 27a and the filling material 27c of the present embodiment are disposed below the substrate 10, 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 case 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 filler 27, a foaming activator (foamed heat insulating material) such as foamed polyurethane may be used. In this case, at the time of manufacturing, after forming the portion other than the filling material 27, a foaming activator is injected into the case 2. The foaming activator injected into the housing 2 foams and fills a substantially entire region of the internal space (filling region) such as (B). The activation method is not limited to the temperature change, and may be a chemical change based on retardation, light, electromagnetic waves, acoustic waves, vibration, or the like. Further, a part of the housing 2 (for example, the opening R1) may be used as an injection port of the foaming activator, and the opening may be finally plugged to adjust the internal pressure. The substrate 10 and the second heat insulating layer 22 may be disposed as shown by injecting and filling the filling material 27 from the inlet of the bottom 2B of the case and raising them upward.

[4-2: Modification examples ]

As a modification of embodiment 4 shown in fig. 20, the following configuration may be adopted, as compared with each of the above embodiments, from the thermodynamic point of view. 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 material having heat absorption property, which has a large heat storage amount or a large thermal capacity. The heat absorbing material absorbs heat from the outside of the housing 2 within a predetermined temperature range and remains at that location. This reduces or suppresses heat conduction from the portion to the electronic circuit component 5 and the like. Likewise, the inner case 2T may be made of a heat absorbing material. The fifth heat insulating layer 25 or the filler 27 may be made of a heat absorbing material. A part of the second heat insulating layer 22 may be made of a heat absorbing material. The heat insulating layer, the filler or the 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 transfer unit 6.

[5-1: Conveying part ]

Fig. 21 shows an example of the configuration of the transport unit 6 in the mouse according to embodiment 5. (A) shows a first example, and (B) shows a second example. In (a), the transmission unit 6 is constituted by 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 upward from the position of the lens 4 in the opening R1 of the case bottom 2B, for example, 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 intermediate the optical fiber 6 f. In other words, the optical fiber 6f of the transmission unit 6 may be constituted by a plurality of optical fibers, and the optical coupler 60 may constitute one transmission path by bundling a 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 the direct transmission of the image light by the optical fiber. The optical coupler 60 may also include an optical fiber coupled to the fourth insulating layer 24. The optical coupler 60 may be used as a binder for binding a plurality of optical fibers.

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

In the example (B), the transfer section 6 is provided as a front wiring from the position of the lens 4 and the opening R1 provided in the vicinity of the left end of the frame bottom 2B, which is the front side of the mouse 1. 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. Thus, the wiring of the transfer unit 6 can be positioned appropriately, and can be positioned at a more thermally advantageous position. The wiring of the transfer unit 6 may be fixed by another member. In this configuration example, the optocoupler 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 at the rear part of 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 structure of the optical element with respect to the case bottom 2B.

[6-1: Optical element ]

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

The housing bottom 2B is constituted by, for example, an outer housing bottom 2B1 and an inner housing bottom 2B 2. In a part of the inner case bottom 2B2, the lens barrel 41 of the lens structure 40 is formed so as to protrude inward in a convex shape. In this example, the lens barrel 41 is fixed by a screw structure 42 in a fixing portion (screw hole) 43 protruding upward from the inner housing bottom 2B 2. Screw structures 42 are 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 case bottom 2B2, the first insulating layer 21 is formed so as to cover the lens barrel 41 and the fixing portion 43. The lens structure 40 has a substantially axisymmetric shape. The axis is shown in a single dot chain line. The space 2300 in the vicinity of the axis of the lens barrel 41 is a region corresponding to the width H1 of the opening R1, and is divided by a plurality of lenses 4A and 4B. In this example, a case having 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 via a member 41a having a screw structure and a sealing material at a lower position, and the lens 4B is fixed via a member 41B having a screw structure and a sealing material at an upper position. The lens 4A has a convex curved surface on the lower side, and the lens 4B has a convex curved surface on the upper side. The space 2300 of the lens barrel 41 is partitioned by lenses 4A and 4B to constitute a light-transmitting heat-insulating portion 2302. The light-transmitting heat-insulating portion 2302 is a layer made of an air layer, a vacuum layer, ar gas, or a light-transmitting heat-insulating material. One end of a transmission unit 6, not shown, is connected to an upper portion of the lens barrel 41.

A 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 water (water vapor) from entering. A heat shielding filter 2301 may be provided in the inner case bottom 2B2 and the lens barrel 41.

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

According to the configuration of embodiment 6 having the lens barrel 41 and the like, the waterproof property in the vicinity of the opening R1 can be improved, and the positioning of the lens and the connection of the lens to the transfer unit 6 can be easily performed. The first space portion SP1 (distance K2 of fig. 2) is also secured by the transfer portion 6, and therefore a lens barrel 41 or the like having a certain level can also be provided. As another configuration example, when a cover having image light transmittance is used as the case bottom 2B1, the opening R1 may be covered with the cover. The light source portion wiring 7d from the light source portion 7 may be connected to the lens structure 40. For example, the light source portion wiring 7d is optically connected to the space portion 2300 by the fixing portion 43 wiring.

[6-2: Modification examples ]

Fig. 22B shows a structure of a mouse in a modification (modification 5) of embodiment 6. This modification extends the lens structure 40 above the Z direction, in other words, increases the Z-direction length of the lens barrel 41 so as to reach the vicinity of the image sensor 15 of the electronic circuit component 5 of the substrate 10. Thus, the linear barrel type lens structure 40 is set as the transfer section 6. The transfer section 6 serves as both a function as an image light incidence section and a function as a transfer path to the image sensor 15. In the lens barrel 41 of the transfer section 6, the upper end in the Z direction extends to, for example, the surface of the image sensor 15 of the electronic circuit part 5 of the substrate 10, and the optical axis of the lens barrel 41 is aligned with the optical axis of the image sensor 15. 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 lens barrel 41 may have a light-transmitting heat insulating material in its entirety or a part.

< 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 the case where the image sensor 15 is disposed at the bottom 2B of the case.

[7-1: Image sensor at bottom of housing

Fig. 23 (a) shows a vertical section of a mouse 1 as a mouse according to embodiment 7. The mouse 1 according to embodiment 7 has the image sensor 15h and the light source 7h arranged in close proximity to each other at a position near the left end (position on the front side in the Y direction) spaced from the bottom 2B of the housing toward the left side in fig. 23. The image sensor 15h is an imaging element (in other words, an image detection unit) disposed at the bottom 2B of the case, and converts image light from the outside (the installation surface SF) into an image signal by incidence. The light source portion 7h is a light emitting element which is disposed at the bottom 2B of the case and emits illumination light to the outside (the 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 unit 7h are connected to the electronic circuit member 5 of the substrate 10 via the wirings 15c and 7c, respectively, which are electric wirings. In this configuration example, based on the control from the electronic circuit component 5, illumination light is emitted downward from the light source portion 7h, and the image sensor 15h converts image light, which is reflected light from the installation surface SF, into an image signal.

In embodiment 7, the transmission unit 6 is not an optical transmission mechanism, but is wirings 15c and 7c serving as electric signal transmission mechanisms. 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 part 7h through the wiring 7c. In this example, the other end of the transfer section 6 is electrically connected to the electronic circuit component 5, but the present invention is not limited to this, and may be connected to the substrate 10, and may be electrically connected to the electronic circuit component 5 or the like through a circuit of the substrate 10. The wiring 15c and the wiring 7c may be integrated into one and covered with the fourth heat insulating layer 24 or the like. The wiring 15c and the wiring 7c serving as the transfer section 6 are front-side wirings in this example, but the present invention is not limited thereto, and the various embodiments described above can be applied.

In the configuration of embodiment 7 shown in (a), the image sensor 15h and the light source 7h are provided with, for example, heat insulation, heat resistance, water resistance, pressure resistance, contamination resistance, and cleaning easiness as components of a part of the configuration which is arranged in the longitudinal direction and the horizontal direction from the central portion of the case bottom 2B toward the front side of the mouse 1. An electronic circuit component 5 and the like which are other components and which are not subjected to heat generation are arranged in a separate position within the housing 2, for example, in a position near the center of the internal space of the housing 2, from the image sensor 15h and the like through a wiring 15c and the like as the transmission section 6. 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 portion 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, in the case where 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 examples ]

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 case bottom 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, the image sensor 15h and the light source 7h have a cover 2601 for enhancing the heat and water generated during the sterilization process, and for avoiding the defects such as heat insulation, heat resistance, water resistance, pressure resistance, contamination resistance, and easy cleaning property, compared with the configuration of (a), on the lower side of the image sensor 15h and the light source 7 h. The cover 2601 also has light transmittance, 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 have an area covering at least the lower surfaces of the image sensor 15h and the light source 7h and to be smooth with respect to the lower surface of the case bottom 2B. That is, the cover 2601 has, for example, light transmittance, heat insulation, heat resistance, water resistance, pressure resistance, contamination resistance, easy cleaning, and the like. The cover 2601 may be provided to cover the entire bottom 2B of the housing, etc., without being limited thereto. The cover 2601 is not limited to one piece, and may be formed of, for example, a plurality of layers including a cover having heat insulation properties and a cover having water resistance. As described above, in this modification, the combination of the arrangement position of the image sensor 15h or the like provided near the left end of fig. 23 of the case bottom 2B and the provision of the cover 2601 ensures necessary heat resistance, water resistance, and the like.

< Embodiment 8>

A mouse according to embodiment 8 of the present invention will be described with reference to fig. 24. The rat in embodiment 8 shows an example of the structure of the substrate 10 having a box shape.

[8-1: Box-shaped substrate ]

Fig. 24 (a) shows a cross-sectional view of the mouse 1 as the mouse of embodiment 8. In the inner space of the case 2 and the first insulating layer 21, a transmission unit 6, not shown, is connected to the lens 4 at the bottom 2B of the case, and is connected to the image sensor 15 of the electronic circuit component 5 on the substrate 10. The wiring of the transfer unit 6 can be applied to the above-described modes. The case bottom 2B and the substrate 10 are arranged at a distance K2 from each other through the fifth heat insulating layer 25 or the second heat insulating layer 22. The substrate 10 has a substantially box shape, and includes a bottom surface portion 10b disposed on a horizontal surface and, for example, four side surface portions 10a standing in the Z direction (side surface portions of the Y-Z surface in fig. 24 are shown). The upper surface portion (in other words, the lid portion) of the box shape of the substrate 10 is not provided. The electronic circuit component 5 and other components are mounted on the bottom surface portion 10b of the substrate 10. For example, the electronic circuit component 5 is disposed near the center in the case 2, and is covered with the third heat insulating layer 23. Further, the other member 10p may be mounted on 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 portions 10a, or a quadrangular shape when viewed in plan, but the shape is not limited thereto, and may be a polygonal shape, or a polygonal shape when viewed in plan. In addition, regarding the box-like structure of the substrate 10, it is necessary to: the reduction of the thermal invasion by reducing the surface area of the box shape as much as possible makes it possible to increase the amount of intervention of the heat insulating material into the space inside the case 2, particularly the first space portion SP1 provided with the fifth heat insulating layer 25 by reducing the generated heat conduction by separating the box shape of the substrate 10 from the inner surface of the case 2 as far as possible. Therefore, the size of the box shape of the substrate 10 is further reduced as much as possible to a three-dimensional shape constituted by the inner surface of the housing 2, and the shape of the box shape of the substrate 10 is preferably a sphere or a prolate sphere (a rotational ellipse), or a sphere, a prolate sphere, or a polyhedron similar thereto having a part of a plane, in addition to the above-described shape. Specifically, the shortest distance between the inner surface of the case 2 and the outer surface of the box shape or the like of the substrate 10 is 3 to 20mm, preferably 13 to 20mm.

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 housing upper portion 2A. The third space SP3 is formed in the box-shaped substrate 10. A fourth space SP4 is formed between the outside of the side surface 10a and the housing 2. In the fourth space portion SP4, for example, in the X direction, a distance K94 is provided from the side surface portion 10a to the outer surface of the housing 2. Thus, the box-shaped substrate 10 is disposed in a compact form by being concentrated in a position near the center of the internal space of the housing 2. In this configuration, therefore, it is difficult for the electronic circuit component 5 and other components to conduct heat in all directions from the outer surface of the case 2. In particular, this configuration secures the distance K94 of the fourth space portion SP4 and the like in each horizontal direction, and intervenes in the side surface portion 10a, so that it is difficult to conduct heat in each horizontal direction. By reducing the surface area of the substrate 10 (the surface area of the box-shaped outer surface), the amount of heat conduction is reduced, and thereby the heat insulating performance involved in protecting the electronic circuit component 5 and the like is improved.

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 heat-insulating coating may be applied to the outer surfaces 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 10 a. The upper surface portion of the box shape may be provided to close the third space portion SP3. In this way, in embodiment 8, by providing the substrate 10 in the shape of a box, the volume ratio of the substrate 10 to the entire internal space of the mouse is reduced, the heat insulation property of the substrate 10 itself is improved, and heat conduction to the electronic circuit component 5 and other components is made difficult, thereby improving the overall heat insulation effect. In addition, the arrangement of other members such as a heat insulating layer can be reduced.

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

In this modification, heat conduction from the outside to the electronic circuit component 5 and other components in the third space portion SP3 is difficult by the cylindrical closed substrate 10. In accordance with the amount, the second heat insulating layer 22 is not provided in this modification. 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 broken line is provided on the entire outer surface of the substrate 10. The thickness of the heat insulating finish 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, in the case where the fifth heat insulating layer 25 is disposed below the substrate 10 as in the present embodiment, an important function of supporting and/or fixing the substrate 10 can be achieved. The present invention is not limited thereto, and the second space SP2 and the fourth space SP4 may be provided with a heat insulating material, a heat absorbing material, or a filler, to position the substrate 10.

< Embodiment 9>

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

This example is a digital board terminal represented by a terminal called "iPad" (trade name: registered trademark).

In addition, the digital board terminal of the present embodiment may be replaced with a mobile terminal as the electronic device of the present invention, and in this case, the structure of the mobile terminal, the arrangement of the optical element or the imaging element, and the electronic circuit component are substantially the same as those of the digital board terminal, and therefore illustration and detailed description are omitted.

In the present embodiment, the tablet terminal 101 includes: a housing 102 composed of a housing upper portion 102A and a housing bottom portion 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, so that 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 component but also to have a laminated structure inside or outside the case 102, or the case 102 may be provided in multiple layers, with the heat insulating material 105 being disposed in the middle thereof. The heat insulating structure similar to or related to the embodiment shown in fig. 1 to 25 may be combined.

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

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

A monitor screen 113 (fig. 27) is provided on the front surface side, i.e., the planar side, of the tablet terminal 101. Unlike the case of electronic devices such as a normal tablet terminal and a mobile terminal, the monitor screen 113 has a small area of, for example, half or less of the planar area of the housing 102. The reason for this is as follows. That is, since the heat insulating structure is reliably provided for the high temperature at the time of sterilization of the autoclave apparatus, the volume or thickness of the inside of the casing at the portion where the monitor screen is located is reduced. If the monitor screen is increased, the thickness is increased by this amount and is difficult to use. Therefore, by reducing the monitor screen 113, a firm heat insulating structure is established at a portion having no thickness of the monitor screen 113, and heat is prevented from being generated at the portion where the electronic component or the like is accommodated. However, with the improvement of heat insulation technology and heat resistance of electronic devices, the digital panel terminal 101 becomes thinner and the monitor screen 113 becomes larger, and thus the development of easy use is expected. Accordingly, 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.

In addition, reference numeral 114 in fig. 26 denotes a screw for a stay in the housing 102, and a plurality of screws 114 are disposed 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 special electronic devices such as a medical field, as in the mouse 1 of the above embodiment, unlike the input and operation electronic devices in a general office computer.

Therefore, in the tablet terminal 101, in order to prevent 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, from being affected by heat, high pressure, and the like caused by high-temperature and high-pressure water vapor during the autoclave process to the maximum extent, the opening 110 and the camera lens 111 for photographing are arranged to be spaced apart from each other in the Z direction by the amount of the first space SP1 to the maximum extent, and thus, the influence of heat, high pressure, and the like caused by high-temperature and high-pressure water vapor during the autoclave process can be prevented to the maximum extent.

That is, as shown in fig. 28, in the Z direction, which is the up-down direction of fig. 28, the distance K1 between the lower surface of the case bottom 102B and the lower surfaces of the IC chip 108 and the image capturing section 109, which are electronic circuit components, and the distance K2 between the upper surface of the case bottom 102B and the lower surface of the substrate 107 in the Z direction, the distance K3 between the IC chip 108 and the upper surface of the image capturing section 109 and the outer surface of the case upper section 102A with respect to the second space SP2 above the IC chip 108 and the image capturing section 109, become maximum.

Further, the IC chip 108 and the image capturing section 109, which are electronic circuit components, are arranged to be spaced apart from each other by the second space SP2 in the Z-direction downward direction from the housing upper portion 102A of the housing 102, and it is possible to prevent the influence of heat, high pressure, and the like caused by high-temperature and high-pressure steam during the autoclave process.

In the tablet terminal 101 of 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 distance K8 (fig. 28) from the opening 110 and the camera lens 111 for photographing as an optical element or a photographing element to the maximum extent in the X direction (the lateral direction in fig. 26 and 28, i.e., the short side direction). 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 maximized at the distance K4B1 on the camera lens 111 side than at the distance K4B2 on the opposite side.

In the tablet terminal 101 of 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) from the opening 110 and the camera lens 111 as an optical element or a photographing element for photographing in the Y direction (the vertical direction in fig. 26, i.e., the longitudinal direction) orthogonal to the X direction. That is, in the longitudinal direction of the tablet terminal 101, as shown in fig. 26, the distance k7+k6 obtained by adding the distance K7 from the image capturing section 109 to the photographing lens 111 and the distance K6 from the photographing lens 111 to the end surface on the opposite side of the longitudinal direction of the housing 102 is larger to the maximum than the distance K4A from the end surface on the near front side of the longitudinal direction of the housing 102 to the image capturing section 109 (k7+k6 > K4A).

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

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 which are electronic circuit components, are disposed so as to be maximally spaced apart from each other in the Z direction, the X direction, and the Y direction from the opening 110 and the camera lens 111 for photographing, respectively, and as a result, the effects of heat, high pressure, and the like caused by high-temperature and high-pressure steam in the autoclave process can be maximally prevented.

In other words, the tablet terminal 101 according to embodiment 9 is a tablet terminal for medical use, and can be applied to sterilization by an autoclave which improves the sanitary environment of a medical field such as a hospital, and when it is desired to use a medical equipment system to which the tablet terminal is connected, for example, in an examination, an operation, or the like, it is possible to reliably prevent infection by using the tablet terminal subjected to sterilization, and to realize advanced medical treatment by using the functions of the system such as a navigation technique. For example, by operating the digitizer terminal by the operator himself, a three-dimensional image can be obtained more reliably, and the quality of the operation and the like can be improved.

Fig. 29 is a schematic cross-sectional view in a plane 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 cross-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 applicable to a so-called intraoral camera as another example of the medical electronic device of the present invention.

In the present embodiment, the intraoral camera 201 includes: a case 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, two secondary batteries 204, an electromagnetic sensor 206, a substrate 207, an IC chip 208, and an image capturing section 209, which are electronic components, are surrounded by a heat insulating material 205 schematically shown by two-dot chain lines, and the heat insulating effect of these electronic components is further improved. The heat insulating material 205 or the same kind of heat insulating material may be disposed not only to surround the electronic component but also to be laminated on the inner side or the outer side of the case 202, or the case 202 may be formed in a plurality of layers, with the heat insulating material 205 disposed in the middle thereof. The heat insulating structure may be combined with the same or related embodiments illustrated in fig. 1 to 25 and fig. 26 to 28.

An opening 210 is formed on the rear surface side of the distal end of the extension 202B of the intraoral camera 201, and a camera lens 211 for photographing, which is 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 202B. The transmission portion 212 can be formed of an optical fiber such as a glass optical fiber.

The intraoral camera 201 of the present embodiment is also, like the mouse 1 and the tablet terminal 101 of the above embodiment, completely different from the input and operation electronic devices in a general office computer, and can withstand severe processing conditions such as sterilization processing by high-temperature and high-pressure steam in a medical autoclave apparatus, and can be used as an intraoral camera applied to special electronic devices in a medical field or the like.

Therefore, in the intraoral camera 201, the substrate 207 on which the IC chip 208 and the image capturing section 209 are mounted, in particular, 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 at the tip of the extension 202B and the camera lens 211 for photographing in the Y direction (longitudinal direction of the intraoral camera 201). As a result, in the intraoral 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 extent.

In the intraoral camera 201 of the present embodiment, the first space SP1 is arranged so as to be spaced apart from the lower outer surface (bottom surface) of the housing 202 to the maximum extent in the Z direction, so that the influence of heat, high pressure, and the like caused by high-temperature and high-pressure steam during the autoclave treatment can be prevented to the maximum extent. That is, the distance K1 from the lower outer surface (bottom surface) of the housing 202 to the lower surface of the substrate 207 is maximized with respect to the distance K3 from the upper outer surface (upper surface) of the housing 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 disposed at a distance from each other in the Z-direction lower direction from the upper outer surface of the case 202 by the amount of the second space SP2, and can prevent the influence of heat, high pressure, and the like caused by high-temperature and high-pressure steam in the autoclave process.

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 so as to be spaced apart from each other to the maximum in the X direction (the left-right direction in fig. 32, i.e., the short-side direction) with respect to the opening 210 and the camera lens 211 as an optical element or a photographing element for photographing.

That is, for example, as shown in fig. 32, the image capturing section 209 is spaced apart from the left outer side surface of the housing 202 by a distance K4B1 in the X direction and 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 (K4B 1> K4B 2), and the distance K4B1 is larger than 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 apart from the camera lens 211 as far as possible in the X direction.

In the substrate 207, as shown in fig. 32, a distance K4G1 from the left end of the substrate 207 to the left outer side surface of the case 202 is larger than a distance K4G2 from the right end of the substrate 207 to the right outer side surface of the case 202 (K4G 1> K4G 2).

Therefore, in the present embodiment, the substrate 207, the IC chip 208 as an electronic circuit component, and the image capturing section 209 are arranged so as to be spaced apart to the maximum extent in all of the X direction, the Y direction, and the X direction from the opening 210 and the camera lens 211 for photographing as an optical element or an imaging element, as viewed from three directions of the Z direction, the X direction, and the Y direction.

That is, in the intraoral camera 201 of the present embodiment, the substrate 207 on which the IC chip 208 and the image capturing section 209 are mounted, in particular, the IC chip 208 and the image capturing section 209 which are electronic circuit components are disposed so as to be maximally spaced apart from each other in the Z direction, the X direction, and the Y direction from the opening 210 and the camera lens 211 for photographing, and thus disposed so as to be maximally spaced apart 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 steam in the autoclave process can be maximally prevented.

In other words, the intraoral camera 201 of embodiment 10 can be used not only for the sterilization treatment by an autoclave, but also for a medical field, and can achieve effects such as prevention of infection and improvement of medical efficiency.

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

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

The embodiments shown in fig. 1 to 25, 26 to 28, and 29 to 32 may be combined with each other or used in combination with each other in, for example, a heat insulating structure, a structure of an optical lens, or the like, and are included in the scope of the present invention.
