Description

Technical Field

[0001] The present invention relates to a colorimetric device that measures color based on light emitted from a measurement object. Background Art

[0002] In electronic devices, the impact buffer structure described in Patent Document 1 is sometimes used so that even if the device is subjected to a large impact due to a phenomenon such as falling, the device body inside the frame will not be subjected to a large impact. The impact buffer structure described in Patent Document 1 is provided with an elastic member between the frame and the device body, and the elastic member is set to an initial state after being compressed from a free length. Moreover, when the device is subjected to an impact due to a phenomenon such as falling, the elastic member is elastically deformed to suppress the impact on the device body inside the frame.

[0042] Hereinafter, the present invention will be briefly described.

[0043] The colorimetric device involved in the first embodiment is characterized in that it comprises: an opening portion for taking light emitted from a measurement object into the interior of the device; an incident light processing portion for processing light incident into the interior of the device through the opening portion; an opening forming member arranged on the bottom surface side of the device to form the opening portion; and an internal unit of the device comprising the incident light processing portion, the internal unit of the device comprising: a fixed unit connected to the opening forming member; a movable unit, which is a unit comprising the incident light processing portion and can be displaced relative to the fixed unit in a first direction along the optical axis of light from the opening portion toward the incident light processing portion; and at least one elastic member for maintaining the position of the movable unit relative to the fixed unit in the first direction by using elastic force.

[0044] According to this aspect, the internal unit of the device includes: the fixed unit; and a movable unit, which is a unit including the incident light processing unit and can be displaced relative to the fixed unit in a first direction along the optical axis of the light from the opening toward the incident light processing unit, and the elastic member realizes impact buffering of the movable unit in the first direction. As a result, it is difficult to cause positional deviation between the opening and the incident light processing unit in a direction intersecting the first direction, and even if an impact buffering structure that buffers the impact applied to the incident light processing unit is adopted, an appropriate color measurement result can be obtained.

[0045] Furthermore, since the shock absorbing structure is provided in the first direction, it is possible to suppress an increase in size and cost of the device compared to a structure in which the shock absorbing structure is provided in a direction having high shock resistance.

[0046] In addition, since the total weight of the internal unit of the device will not be applied to the impact buffer structure, only the weight of the movable unit is applied to the elastic component, i.e. the impact buffer structure, the size and cost increase of the impact buffer structure can be suppressed, and the size and cost increase of the device can be suppressed.

[0047] The second method is characterized in that, based on the first method, the fixed unit includes: a first unit, which is connected to the opening forming member; a second unit, which is located on a side away from the opening forming member relative to the first unit in the first direction and is connected to the first unit in a state of being separated from the first unit along the first direction; and a guide shaft, which extends along the first direction in the gap between the first unit and the second unit, and the movable unit includes a guided portion, which is located between the first unit and the second unit and is guided by the guide shaft.

[0048] According to this aspect, it is possible to obtain a device in which the movable unit can be displaced in the first direction with a simple structure and at low cost.

[0049] A third aspect is characterized in that, in addition to the second aspect, the elastic member is provided between the first unit and the guided portion and between the second unit and the guided portion in a state where a free length in the first direction is shortened.

[0050] According to this method, the elastic member is arranged between the first unit and the guided portion and between the second unit and the guided portion in a state where the free length in the first direction is shortened, so that the elastic member is always in a compressed state, thereby stabilizing the position of the movable unit in the first direction and making it difficult for the setting position of the elastic member to deviate in a direction intersecting the first direction.

[0051] A fourth aspect, in addition to the third aspect, is characterized in that a center of gravity position of the elastic member when viewed from the first direction is located at a position corresponding to a center of gravity position of the movable unit.

[0052] According to this embodiment, since the center of gravity of the elastic member when viewed from the first direction is located at a position corresponding to the center of gravity of the movable unit, when the movable unit overcomes the elasticity of the elastic member and displaces along the first direction, it is difficult to generate a force in a direction intersecting the first direction on the movable unit. Thus, the movable unit can be smoothly displaced along the first direction.

[0053] A fifth aspect is characterized in that, in any one of the first to fourth aspects, a battery as a power supply source for the device is provided in the fixing unit.

[0054] According to this method, the battery serving as the power supply source for the device is not arranged in the movable unit but in the fixed unit. Therefore, the weight of the battery as a heavy object will not be applied to the elastic component, i.e., the impact buffer structure. The enlargement and cost increase of the elastic component can also be suppressed, and the enlargement and cost increase of the device can be suppressed.

[0055] The sixth mode is characterized in that, based on any one of the first to fifth modes, the incident light processing portion comprises: a wavelength-variable optical filter that transmits a specified wavelength component in the incident light; and a light receiving portion that receives the light that has passed through the optical filter, and the movable unit comprises: a first circuit substrate that has the optical filter; and a frame that is arranged at a position opposite to the optical filter arranged on the first circuit substrate and has an aperture portion that reduces the amount of light that passes through the opening portion toward the optical filter, and a gap between the frame and the optical filter is filled with a plastic member.

[0056] The optical filter is a precision part. If an external force is applied in the first direction, the color measurement result will be adversely affected. Therefore, a gap needs to be formed between the two so that the frame does not contact the optical filter. However, if the optical filter is subjected to an impact caused by falling, the components constituting the optical filter may peel off in the first direction. Based on this point of view, it is possible to form a gap between the frame and the optical filter and place an elastic member or the like between the gap. However, if the elastic member is used, external force always acts on the optical filter, so it is not preferred.

[0057] Based on such a viewpoint, in this method, the gap between the frame and the optical filter is filled with a plastic member, so that it is difficult for an external force to act on the optical filter under normal circumstances, and when an impact is applied, the optical filter can be supported by the plastic member, and the peeling of the components constituting the optical filter can be suppressed.

[0058] A seventh aspect, based on the sixth aspect, is characterized in that the optical filter is a Fabry-Perot etalon.

[0059] According to this aspect, in a configuration in which the optical filter is a Fabry-Perot etalon, the effects of the sixth aspect described above can be obtained.

[0060] The eighth mode is characterized in that, based on any one of the first to fourth modes, the movable unit comprises: a first circuit substrate comprising the incident light processing unit; a second circuit substrate comprising a light emitting unit for emitting light for measurement; and a third circuit substrate for connecting a battery serving as a power supply source for the device, and the fixed unit comprises a fourth circuit substrate for connecting a display unit which is located on the upper surface of the device and performs various displays, and in the first direction, the second circuit substrate, the first circuit substrate, the third circuit substrate, the battery and the fourth circuit substrate are arranged in an overlapping manner in sequence from the opening forming member toward the display unit.

[0061] According to this embodiment, since the second circuit substrate, the first circuit substrate, the third circuit substrate, the battery and the fourth circuit substrate are arranged in an overlapping manner in sequence from the opening forming member toward the display portion in the first direction, the device size in the direction intersecting the first direction can be suppressed.

[0062] Hereinafter, the present invention will be described in detail.

[0063] In addition, the XYZ coordinate system shown in each figure is an orthogonal coordinate system, the XY plane is a horizontal plane, and the YZ plane is a vertical plane.

[0064] In addition, the Z-axis direction is a vertical direction and is an example of a first direction intersecting the upper surface 50e and the bottom surface 50f of the colorimetric device 1. In addition, the first direction is a direction parallel to the optical axis CL described later. In addition, the Y-axis direction is a direction orthogonal to the first direction, and becomes the long side direction of the device when the colorimetric device 1 is observed from the Z-axis direction. In addition, the X-axis direction is a direction orthogonal to the Y-axis direction, and becomes the short side direction of the device when the colorimetric device 1 is observed from the Z-axis direction.

[0065] In this specification, the configuration of the colorimetric device 1 is described assuming that the bottom surface 50 f is placed on a placement surface parallel to a horizontal plane and the longitudinal direction of the colorimetric device 1 is along the Y-axis direction.

[0066] Overall structure of the color measuring device 1

[0067] First, refer to Figure 1 and Figure 2 , the overall structure of the colorimetric device 1 of this embodiment is summarized mainly from the functional point of view.

[0068] The colorimetric device 1 has a configuration for performing colorimetric measurement based on light emitted from the measurement target 200. Examples of the light emitted from the measurement target 200 include light reflected from the measurement target 200 and light emitted from the measurement target 200 itself.

[0069] The colorimetric device 1 includes a bandpass filter 7, an optical filter 3, a light receiving unit 4, an electrostatic capacitance detecting unit 6, a light emitting unit 9, an MCU (Micro Controller Unit) 10, a wired IF (Interface) 12, a wireless communication unit 13, an operating unit 14, a display unit 15, a battery control unit 16, and a battery 17.

[0070] The optical filter 3 and the light receiving unit 4 constitute an incident light processing unit 2 that processes incident light emitted from the measurement target 200 .

[0071] The bandpass filter 7 transmits the light in the visible light region, for example, 380 nm to 720 nm, among the light incident from the measurement object 200, and cuts off the light in the ultraviolet light region and the infrared light region. Thus, the light in the visible light region is incident on the optical filter 3. In addition, the light sent from the measurement object 200 to the bandpass filter 7 is transmitted from the opening 21a (see FIG. 21A ) described later. Figure 5 ) is taken into the device and then passes through the measurement window 87a (refer to Figure 5 ) reaches the bandpass filter 7.

[0072] The optical filter 3 selectively transmits any wavelength component from the visible light that has passed through the bandpass filter 7. The light that has passed through the optical filter 3 is incident on the photodiode 4a, which is an example of a light receiving element, and is processed by the light receiving unit 4 having the photodiode 4a. The light receiving unit 4 converts the intensity of the received light into a voltage value, further converts the voltage value into a digital signal, and outputs the digital signal to the MCU 10. The colorimetric device 1 can measure the spectrum of the measurement object 200 by repeatedly performing wavelength selection based on the optical filter 3 and obtaining the intensity of the received light using the light receiving unit 4.

[0073] Here, refer to Figure 2 The structure of the optical filter 3 will be described. In the present embodiment, the optical filter 3 is a wavelength-variable Fabry-Perot etalon that transmits a predetermined wavelength component of incident light from the measurement object 200 and is a wavelength filter that utilizes multiple interference of two opposing reflection surfaces.

[0074] exist Figure 2 In FIG. 4 , the optical filter 3 includes a variable wavelength interference filter 45 , and the variable wavelength interference filter 45 is built inside an exterior composed of the first glass member 30 , the second glass member 31 , and the housing 32 .

[0075] The housing 32 and the first glass member 30, and the housing 32 and the second glass member 31 are bonded by bonding members 33 such as low melting point glass and epoxy resin. In addition, the variable wavelength interference filter 45 and the housing 32 are fixed by a fixing material 34 such as an adhesive. The electrode 36 on the outer surface of the housing 32 and the variable wavelength interference filter 45 are connected by wire bonding 35 and wiring in the housing 32.

[0076] The variable wavelength interference filter 45 includes a base substrate 37 and a diaphragm substrate 38. The base substrate 37 and the diaphragm substrate 38 are bonded together by a bonding film 43. Reflection mirrors 39 are formed on the base substrate 37 and the diaphragm substrate 38, respectively. The outermost surfaces of the opposing reflection mirrors 39 are formed of a conductor. Furthermore, the electrostatic capacitance between the opposing reflection mirrors 39 is detected by the electrostatic capacitance detection unit 6 (see Figure 1The electrostatic capacitance detection unit 6 is composed of a CV (Capacitance to Voltage) converter, and converts the detected electrostatic capacitance into a voltage value, and further converts it into a digital value, and sends it to the MCU 10.

[0077] The distance between the opposing reflection mirrors 39 is controlled by an electrostatic actuator constituted by a fixed electrode 40 and a movable electrode 41 that are formed in a concentric circle shape when viewed from the Z-axis direction and face each other.

[0078] When a voltage is applied between the fixed electrode 40 and the movable electrode 41 facing each other, a force that attracts the fixed electrode 40 and the movable electrode 41 to each other is generated due to electrostatic force. At this time, the diaphragm portion 42 formed in a concentric circle shape is deformed, and the reflector 39 of the diaphragm substrate 38 is pulled toward the base substrate 37 side, and the distance between the facing reflectors 39 is controlled. And the wavelength of light passing through the variable wavelength interference filter 45 is selected according to the distance between the facing reflectors 39.

[0079] During spectroscopic measurement, light from the measurement object 200 is incident on the optical filter 3 from the second glass member 31 side to the first glass member 30 side along the optical axis CL. The optical axis CL is parallel to the Z-axis direction and is formed through the opening 21a (see Figure 5 )、Measurement window 87a (refer to Figure 5 ), the wavelength variable interference filter 45 and the center of the photodiode 4a. In particular, the opening 21a, the measurement window 87a and the wavelength variable interference filter 45 are in a perfect circular shape when viewed from the Z-axis direction, and the optical axis CL passes through their centers. In addition, the optical axis CL is sometimes referred to as the center position CL below.

[0080] Then, the light incident on the optical filter 3 interferes between the opposing reflectors 39, and the light of the wavelength selected corresponding to the distance between the opposing reflectors 39 passes through the variable wavelength interference filter 45. The light passing through the variable wavelength interference filter 45 passes through the first glass member 30 through the opening 32a of the housing 32 and heads toward the light receiving unit 4. The opening 32a of the housing 32 is an opening in a perfect circular shape centered on the optical axis CL.

[0081] The above is the structure of the optical filter 3. In addition, as described above, the optical filter 3 is a structure that selects the wavelength of the transmitted light corresponding to the distance between the opposing reflectors 39 in the variable wavelength interference filter 45, and therefore, is not resistant to the impact in the Z-axis direction, that is, the measurement accuracy is easily reduced with the impact in the Z-axis direction. On the other hand, it can be said that the optical filter 3 is a structure that is relatively strong to the impact in the direction intersecting the Z-axis direction.

[0082] return Figure 1The MCU 10 is a microprocessor-based control device, and has a built-in memory storing various programs and data required for controlling the colorimetric device 1 .

[0083] MCU10 will refer to Figure 2 The control information required for driving the electrostatic actuator formed by the fixed electrode 40 and the movable electrode 41 described above facing each other is sent to an amplifier (not shown), and a predetermined driving voltage is supplied from the amplifier to the optical filter 3. In addition, the MPU 10 compares the information related to the voltage value output from the electrostatic capacitance detection unit 6 with the stored value, and performs feedback control on the optical filter 3 based on the information.

[0084] The light emitting unit 9 emits light for measurement toward the measurement object 200. The light emitting unit 9 is composed of a plurality of light emitting elements having different wavelength distributions, specifically, a plurality of LEDs. The MCU 10 controls the light emitting unit 9 to turn on and off.

[0085] The wired IF12 and the wireless communication unit 13 are components for communicating with an external device. In the standard for communicating via the wired IF12, USB (Universal Serial Bus) can be used as an example. In addition, in the standard of the wireless communication unit 13, Bluetooth can be used as an example. USB and Bluetooth are registered trademarks. The MCU10 sends various data to the external device via the wired IF12 or the wireless communication unit 13, and receives various data from the external device. In addition, the colorimetric device 1 can charge the battery 17 by receiving power supply from the external device via the wired IF12.

[0086] The operation unit 14 is composed of a power button and various operation setting buttons, and transmits a signal corresponding to an operation to the MCU 10. The operation unit 14 will be described further later.

[0087] As an example, the display unit 15 is constituted by a liquid crystal panel, and displays a user interface for setting color measurement conditions, color measurement results, and other information based on a signal sent from the MCU 10 .

[0088] The shutter sensor 114 that sends a detection signal to the MCU 10 is a sensor for detecting the position of the shutter unit 110 described later.

[0089] The battery 17 is a lithium ion secondary battery in this embodiment, and supplies power to various components that require power in the colorimetric device 1. Components that receive power from the battery 17 include the incident light processing unit 2 described below. The battery control unit 16 performs various controls such as charging control of the battery 17.

The opening forming member 21 is formed in a shape extending over the entire bottom of the device.

[0109] The measurement light emitted from the light emitting unit 9 is as follows: Fig.10 As shown by arrow a inside the middle opening 21a, the light passes between the cylindrical portion 87b of the light focusing member 87 and the opening forming member 21, and is emitted from the opening 21a toward the measurement object 200. Then, the light emitted from the measurement object 200 is taken into the device through the opening 21a, and then enters the band pass filter 7 through the measurement window 87a. The light focusing member 87 is an example of a cylindrical member that forms a path for light from the measurement object 200 toward the aperture portion 89a described later.

[0110] In addition, if Figure 6 As shown in FIG. 1 , the optical axis CL coincides with the central axis of the opening 21a and the measurement window 87a.

The gripping portion 50g is composed of a recessed portion 51g formed on the right wall portion 51b and the left wall portion 51c of the main frame 51. The recessed portion 51g is formed by a curved surface that is directed toward the center of the device body 50 in the X-axis direction as it is directed toward the -Z direction.

[0116] By providing the grip portion 50g, the user can grip the device body 50 easily and reliably.

The elastic member 28 is also interposed between the first end 17a, which is the end in the +Y direction of the battery 17, and the battery limiting portion 101f. In addition, the elastic member 28 is also interposed between the second end 17b, which is the end in the -Y direction of the battery 17, and the rear inner wall surface 51f of the main frame 51. Thus, the Y-direction position of the battery 17 in the battery holding portion 100a is limited. As the elastic member 28, for example, a sponge can be used.

[0149] Here, refer to Fig.31 The battery support portion 102a constitutes a first wall portion W1 that supports the battery 17 from below. In addition, the horizontal portion 101b is opposite to the battery support portion 102a and constitutes a second wall portion W2 located above the battery 17. In addition, the battery holding portion 100a has a third wall portion W3 and a fourth wall portion W4 located on the side of the battery 17 in a manner of sandwiching the battery 17, wherein the third wall portion W3 is constituted by the second vertical portion 101c and the second vertical portion 102c, and the fourth wall portion W4 is constituted by the first vertical portion 101a and the first vertical portion 102b.

[0154] Fig.25 1 shows a frame assembly constituting the fixing unit 1 b . The frame assembly constituting the fixing unit 1 b is constituted by connecting the battery holding portion 100 a and the bottom frame 106 .

[0155] More specifically, the bottom frame 106 is formed to include a base portion 106 a constituting a frame surface parallel to the YZ plane and a guide support portion 106 b constituting a frame surface parallel to the XY plane.

In the present embodiment, the guide shaft 107 is a metal shaft extending in the Z-axis direction and is fixed to a hole (not shown) formed in the guide support part 106b by riveting. The guide shaft 107 extends from the guide support part 106b in the +Z direction to a position where the end in the +Z direction is substantially coplanar with the upper surface of the battery support part 102a. A hole (not shown) is formed in the battery support part 102a for the guide support part 106b to pass through.

[0157] The guide support portion 106b is provided with three locations for fixing screws Z6 (see Fig.24 ) of the screw hole (not shown), and three screws Z6 are respectively fixed to the above-mentioned screw holes in a state of being inserted through the tube 108, thereby connecting the battery holding part 100a and the bottom frame 106.

[0158] In this embodiment, the pipe 108 is a metal pipe, and the distance in the Z-axis direction between the battery holder 100a and the bottom frame 106 is defined by the pipe 108. Heat is transferred between the battery holder 100a and the bottom frame 106 by the pipe 108 and the screw Z6.

[0159] In this way, the battery holding portion 100 a and the bottom frame 106 are connected to each other with a gap therebetween in the Z-axis direction, that is, the first unit 1 c and the second unit 1 d are connected to each other with a gap therebetween in the Z-axis direction.

[0160] In addition, in this specification, when a "threaded hole" is referred to, unless otherwise specified, it means a hole with a spiral groove formed for fixing a screw, and when a "screw insertion hole" is referred to, unless otherwise specified, it means a hole that does not have a spiral groove formed and is used only for inserting a screw.

[0161] Next, in the bottom frame 106, a bent portion 106c is formed so as to extend from the -Y direction end of the base portion 106a in the -X direction, and a connecting portion 106e is formed so as to extend from the bent portion 106c in the +Y direction.

In addition, the end of the opening forming member 21 in the +Y direction is fixed to the connecting portion 106f by a screw not shown.

[0163] The opening forming member 21 is formed of a metal material in this embodiment, and is formed of aluminum as an example. Thus, the heat of the bottom frame 106 is transferred to the opening forming member 21. The bottom frame 106 is connected to the bottom frame 106 through the pipe 108 and the screw Z6 (see Fig.24 ) is connected to the battery holding portion 100a, so the heat generated by the battery 17 is also released to the outside of the device through the bottom frame 106 and the opening forming member 21.

[0164] Alternatively, the opening forming member 21 may be formed of a resin material.

[0165] Next, regarding the structure of the movable unit 1e constituting the internal unit 1a of the device, refer mainly to Fig.12 , Fig.13 , Figure 26 to Figure 29 , and the description will be made with reference to other drawings as needed.

The substrate support portions 103f and 103g support the light receiving unit substrate 80. The substrate support portions 103f and 103g are in surface contact with the light receiving unit substrate 80, whereby the heat of the light receiving unit substrate 80 is transferred to the light receiving unit substrate holding frame 103.

[0177] An opening 103b, a positioning hole 103c, and a long hole 103d long in the X-axis direction are formed in the base portion 103a of the light receiving unit substrate holding frame 103. In addition, a screw hole 103k and a convex portion 103h are formed in the substrate support portion 103f, and a screw hole 103m and a convex portion 103j are formed in the substrate support portion 103g.

[0178] like Fig.14 As shown in FIG. 1 , a positioning hole 80a and a screw insertion hole 80b are formed at the end in the +Y direction in the light receiving unit substrate 80. The convex portion 103h of the light receiving unit substrate holding frame 103 is engaged with the positioning hole 80a. The screw insertion hole 80b is provided with a screw Z11 (see FIG. 1 ) for fixing the light receiving unit substrate 80 to the substrate support portion 103f. Fig.13) plugged in.

[0179] In addition, if Fig.14 As shown, in the light receiving unit substrate 80, a screw insertion hole 80c and a long hole 80d which is long in the Y axis direction are formed at the end in the -Y direction. The screw insertion hole 80c is provided with a screw Z11 (see FIG. 1 ) for fixing the light receiving unit substrate 80 to the substrate support portion 103g. Fig.13 The protrusion 103j of the light receiving unit substrate holding frame 103 is fitted into the long hole 80d.

[0180] The positions of the light receiving unit substrate holding frame 103 and the light receiving unit substrate 80 in the X-axis direction are determined by the engagement of the convex portion 103h with the positioning hole 80a and the engagement of the convex portion 103h with the long hole 80d. In addition, since the long hole 80d is a hole that is long in the Y-axis direction, the positions of the light receiving unit substrate holding frame 103 and the light receiving unit substrate 80 in the Y-axis direction are determined by the engagement of the convex portion 103h with the positioning hole 80a.

[0181] As described above, the positioning hole 80a and the projection 103h, and the long hole 80d and the projection 103j constitute the positioning mechanism 90 for determining the relative positions of the light receiving unit substrate 80 and the light receiving unit substrate holding frame 103 in the direction intersecting the Z-axis direction.

[0182] Then, if Fig.15 As shown, the aperture forming member 89, the intermediate member 88 and the light focusing member 87 are positioned on the light receiving unit substrate holding frame 103. In this embodiment, the aperture forming member 89, the intermediate member 88 and the light focusing member 87 are all formed of a black resin material.

[0183] like Fig.18 , Fig.19 As shown, these three members are positioned by the first protrusion 87d and the second protrusion 87e formed on the focusing member 87. The first protrusion 87d is inserted through the positioning hole 88b formed in the intermediate member 88, and further inserted through the positioning hole 89b formed in the aperture portion forming member 89. The second protrusion 87e is inserted through the long hole 88c formed in the intermediate member 88, and further inserted through the long hole 89c formed in the aperture portion forming member 89.

[0184] Here, since the long holes 88c and 89c are long holes in the X-axis direction, the relative positions of the three components in the X-axis direction are determined by the first protrusion 87d being inserted through the positioning hole 88b and the positioning hole 89b. In addition, the relative positions of the three components in the Y-axis direction are determined by the first protrusion 87d and the second protrusion 87e.

[0185] The first protrusion 87d is aligned with a positioning hole 103c (see Fig.15 , Fig.17) are engaged with each other, thereby defining the positions of the above three components in the X-axis direction and the Y-axis direction with respect to the light receiving unit substrate holding frame 103. In addition, the second protrusion 87e enters the long hole 103d formed in the light receiving unit substrate holding frame 103. The long hole 103d is a long hole that is long in the X-axis direction, so the engagement of the second protrusion 87e with the long hole 103d defines the positions of the above three components in the Y-axis direction with respect to the light receiving unit substrate holding frame 103.

[0186] In addition, if Fig.19 As shown, a screw insertion hole 89d is formed in the aperture portion forming member 89, a screw insertion hole 88d is formed in the intermediate member 88, and a screw insertion hole 87f is formed in the focusing member 87. Screw Z5 (see Fig. 27 ) are inserted through these screw insertion holes and the screw insertion holes 104g formed in the light emitting portion substrate holding frame 104 (see Fig.29 ), the screw Z5 is engaged with the threaded hole 103e of the light receiving unit substrate holding frame 103, thereby fixing the above three components together with the light emitting unit substrate holding frame 104 to the light receiving unit substrate holding frame 103.

[0187] In addition, if Fig.18 As shown, the light focusing member 87 has a disk-shaped second base portion 87g formed on the first base portion 87c, and the second base portion 87g is aligned with the opening portion 104e (see Fig.29 ) are integrated.

[0188] Then, if Fig.19 As shown in FIG. 1 , a disc-shaped convex portion 89e is formed on the aperture portion forming member 89, and an aperture portion 89a is formed at the center thereof. The aperture portion 89a is in a perfect circular shape when viewed from the Z-axis direction. Fig.10 As shown, it functions as an aperture section that reduces the amount of light that passes through the bandpass filter 7 and heads toward the optical filter 3 (incident light processing section 2). The light receiving section substrate holding frame 103 is disposed opposite to the light receiving section substrate 80, and is provided with substrate support portions 103f and 103g formed at a position one step higher in the +Z direction from the base portion 103a so as to be a frame in a shape that avoids the optical filter 3, and is an example of a frame that fixes the aperture section forming member 89 and the light receiving section substrate 80.

[0189] In addition, the convex portion 89e is aligned with the opening portion 103b (see Fig.15 , Fig.17 ) are integrated.

[0190] Here, if Fig. 20 , Fig.10As shown, the gap between the light receiving unit substrate holding frame 103 and the optical filter 3 is filled with the plastic member 8. That is, when an external force acts on the optical filter 3 in the Z-axis direction, the color measurement result is adversely affected, so it is necessary to form a gap between the light receiving unit substrate holding frame 103 and the optical filter 3 so that the light receiving unit substrate holding frame 103 does not contact the optical filter 3. However, if the optical filter 3 is subjected to an impact caused by falling or the like, the components constituting the optical filter 3 may also be peeled off in the Z-axis direction. Based on this viewpoint, it is conceivable to form a gap between the light receiving unit substrate holding frame 103 and the optical filter 3 and to interpose an elastic material or the like in the gap. However, if the elastic material is used, the external force always acts on the optical filter 3, so it is not preferred.

[0191] Based on this viewpoint, in the present embodiment, the gap between the light receiving unit substrate holding frame 103 and the optical filter 3 is filled with the plastic member 8. Thus, it is difficult for external force to act on the optical filter 3 under normal circumstances, and when an impact is applied, the optical filter 3 can be supported by the plastic member 8, and the peeling of the components constituting the optical filter 3 can be suppressed.

[0192] As the plastic member 8 , for example, acrylic gel can be used.

[0193] Next, the movable unit 1e constructed as above is constructed as follows: Figure 8 As shown, the guided portion 105b of the movable frame 105 enters between the first unit 1c and the second unit 1d constituting the fixed unit 1b. When the guided portion 105b enters between the first unit 1c and the second unit 1d, the tube 108 passes through the tube insertion hole 105c (see Fig.12 , Fig.26 ), and the guide shaft 107 passes through the guided holes 105d and 105e formed in the guided portion 105b (see Fig.12 , Fig.26 ).

[0194] Thus, the movable frame 105, that is, the movable unit 1e can be displaced in the Z-axis direction relative to the fixed unit 1b.

[0195] The inner diameter of the tube insertion hole 105c is formed to have a margin relative to the outer diameter of the tube 108, so that the contact between the tube 108 and the tube insertion hole 105c does not become a large resistance to the displacement of the movable unit 1e.

[0196] Unlike the guided hole 105d, the guided hole 105e is formed in an elliptical shape slightly elongated in the Y-axis direction. Thus, the Y-axis direction position of the movable unit 1e relative to the fixed unit 1b is defined by the fit between the guided hole 105d and the guide shaft 107 .

[0197] In addition, the X-axis direction position of the movable unit 1e relative to the fixed unit 1b is defined by the insertion of the guide shaft 107 into the guided hole 105d and the insertion of the guide shaft 107 into the guided hole 105e.

[0198] like Fig. 9 , Fig.31 As shown, an elastic member 95 is provided between the guided portion 105b and the first unit 1c and between the guided portion 105b and the second unit 1d. In the assembled state, the elastic member 95 is provided in a state where the free length is shortened, and exerts a pressing force between the guided portion 105b and the first unit 1c, and exerts a pressing force between the guided portion 105b and the second unit 1d, thereby maintaining the position of the movable unit 1e relative to the fixed unit 1b in the Z-axis direction. In addition, when an impact in the Z-axis direction is applied to the internal unit 1a of the device, the impact applied to the movable unit 1e is mitigated by the elastic force of the elastic member 95.

[0199] In addition, as the elastic member 95 , for example, polyurethane foam can be used.

[0200] The thickness, hardness and area on the XY plane of the elastic member 95 in the Z-axis direction are preferably selected so that when vibration or impact is applied to the internal unit 1a of the device or when the device is left for a long time, no gap due to the absence of the elastic member 95 is generated between the guided portion 105b and the first unit 1c and between the guided portion 105b and the second unit 1d.

[0201] The connection structure between the internal unit and the frame of the device

[0202] Next, the connection structure between the device internal unit 1a and the housing will be described.

[0203] like Fig.32 As shown, the upper inner side of the main frame 51 is provided with unit fixing portions 51m and 51n forming a surface parallel to the XY plane. The contact portion 101d (see FIG. 1 ) formed on the first battery holding frame 101 is fixed to the unit fixing portion 51m by screws Z9. Figure 7 The contact portion 101d forms a surface parallel to the XY plane and is in surface contact with the unit fixing portion 51m.

[0204] Similarly, the contact portion 101e (see FIG. 101 ) formed on the first battery holding frame 101 is fixed to the unit fixing portion 51n by means of screws Z9. Figure 7 The contact portion 101e forms a surface parallel to the XY plane and is in surface contact with the unit fixing portion 51n.

[0205] As a result, the device internal unit 1 a is connected to the main housing 51 so as to be held on the upper portion of the main housing 51 .

[0206] An upper housing 52 (see FIG. 1 ) surrounding the operation unit 14 and the display unit 15 is formed on the upper portion of the colorimetric device 1 . Figure 3 ) is inserted into screw holes 51p formed at four corners of the upper portion of the main frame 51 (see Fig.11 ) is fixed to the main frame 51.

[0207] In addition, the opening forming member 21 (see Figure 5 , Fig. 9 ) is screwed to the connection parts 106f and 106e of the bottom frame 106 provided at the bottom of the internal unit 1a of the device as described above (see Fig.23 ). In addition, the bottom first frame 53A constituting the periphery of the bottom of the colorimetric device 1 is also formed by Fig. 9 The bottom second frame 53B is screwed to the bottom frame 106 by screws Z14 and the like. Fig. 9 The screws Z13 shown are fixed to the bottom frame 106 together with the opening forming member 21 .

[0208] In addition, when each frame is assembled, Fig. 9 The portion indicated by reference numeral B1 in the figure, i.e., the connection portion between the main frame 51 and the upper frame 52, is configured so that the main frame 51 and the upper frame 52 overlap each other differently in the direction from the outside of the device toward the inside of the device (see also Fig.11 ). Similarly, the portion indicated by reference numeral B2, i.e., the connection portion between the main frame 51 and the bottom first frame 53A and the connection portion between the main frame 51 and the bottom second frame 53B are also configured to overlap each other differently in the direction from the outside of the device toward the inside of the device. Thus, dust and light can be prevented from entering the inside of the device from the outside of the device.

[0209] In addition, in the main frame 51, the configuration position of the wired IF12 is formed into an opening shape, and there is a risk of dust and light from outside the device entering the inside of the device. However, a cover member 27 is provided at the configuration position of the wired IF12, and the cover member 27 prevents dust and light from entering the inside of the device.

[0210] Characteristic structure and effect of color measurement device

[0211] Hereinafter, the characteristic structure of the colorimetric device 1 configured as described above and its operation and effects will be described.

[0212] First, the main reference Figure 7The internal unit 1a of the device comprises: a fixed unit 1b connected to the main frame 51 and the opening forming member 21; a movable unit 1e, which is a unit having an incident light processing unit 2 and can be displaced relative to the fixed unit 1b in the Z-axis direction along the optical axis of the light from the opening 21a toward the incident light processing unit 2; at least one elastic member 95 (refer to Fig. 9 , Fig.31 ), the position of the movable unit 1e in the Z-axis direction relative to the fixed unit 1b is maintained by elasticity. Moreover, the structure is such that the impact buffering of the movable unit 1e in the Z-axis direction is realized by the elastic member 95. As a result, it is difficult to cause positional deviation between the opening 21a and the incident light processing unit 2 in the direction intersecting the Z-axis direction, and even if an impact buffering structure for buffering the impact applied to the incident light processing unit 2 is adopted, an appropriate colorimetric result can be obtained.

[0213] In addition, since the impact buffering structure is adopted in the Z-axis direction, the enlargement and cost increase of the device can be suppressed compared with the structure in which the impact buffering structure is provided in the direction with high impact resistance. In addition, in this embodiment, the direction with high impact resistance is the direction intersecting with the Z-axis direction.

[0214] In addition, the total weight of the internal unit 1a of the device is not applied to the impact buffering structure, namely the elastic component 95, and only the weight of the movable unit 1e is applied to the elastic component 95. Therefore, the size and cost increase of the elastic component 95 can be suppressed, and the size and cost increase of the device can be suppressed.

[0215] In addition, for example, the interval between the guided portion 105b and the movable unit 1e may be eliminated, that is, the space between the guided portion 105b and the movable unit 1e may be omitted. Fig. 9 , Fig.31 The upper elastic member 95 shown is provided only on the lower elastic member 95. This can suppress the impact in the Z-axis direction applied to the movable unit 1e when the device is dropped with the bottom surface 50f facing downward.

[0216] In addition, the fixed unit 1b includes: a first unit 1c connected to the opening forming member 21; a second unit 1d located on the side away from the opening forming member 21 relative to the first unit 1c in the Z-axis direction and connected to the first unit 1c in a state where a gap is left between the first unit 1c in the Z-axis direction; and a guide shaft 107 extending along the Z-axis direction between the first unit 1c and the second unit 1d. Furthermore, the movable unit 1e includes a guided portion 105b interposed between the first unit 1c and the second unit 1d and guided by the guide shaft 107. Thus, a device in which the movable unit 1e can be displaced in the Z-axis direction can be obtained with a simple structure at low cost.

[0217] In addition, the elastic member 95 is provided between the first unit 1c and the guided portion 105b and between the second unit 1d and the guided portion 105b in a state where the free length in the Z-axis direction is reduced. Thus, the elastic member 95 is always compressed, so the position of the movable unit 1e in the Z-axis direction is stable, and the setting position of the elastic member 95 is unlikely to deviate in a direction intersecting the Z-axis direction.

[0218] In addition, if Fig.30 As shown in FIG. 1 , the center of gravity position P2 of the elastic member 95 when viewed from the Z-axis direction is located at a position corresponding to the center of gravity position P1 of the movable unit 1e. Therefore, when the movable unit 1e is displaced along the Z-axis direction by overcoming the elasticity of the elastic member 95, it is difficult for a force in a direction intersecting the Z-axis direction to be generated with respect to the movable unit 1e. Therefore, the movable unit 1e can be smoothly displaced along the Z-axis direction.

[0219] The center of gravity position P2 of the elastic member 95 being located at a position corresponding to the center of gravity position P1 of the movable unit 1e does not necessarily mean that the center of gravity position P2 and the center of gravity position P1 are completely consistent when viewed from the Z-axis direction, but may be slightly offset within a range that can achieve the above-mentioned effects.

[0220] In addition, if Figure 7 As shown, the battery 17 serving as the power supply source of the device is arranged in the fixed unit 1b, so the weight of the battery 17 as a heavy object will not be applied to the elastic component 95, that is, the impact buffering structure, and the size and cost increase of the elastic component 95 can be suppressed, and the size and cost increase of the device can be suppressed.

[0221] In addition, if Fig. 9 As shown, the light emitting portion substrate 85, the light receiving portion substrate 80, the battery control substrate 70 and the panel substrate 65 are sequentially overlapped and arranged from the opening forming member 21 toward the display portion 15 in the Z-axis direction, thereby being able to suppress the device size in the direction intersecting the Z-axis direction.

[0222] In addition, the structure in which the internal unit 1a is composed of the fixed unit 1b and the movable unit 1e, and the position of the movable unit 1e relative to the fixed unit 1b is maintained by the elasticity of the elastic member 95 can also be applied to other electronic devices. Such an electronic device comprises: a frame body, which forms the outer shell of the device; and the internal unit of the device, which is arranged inside the frame body, and the internal unit of the device comprises: a fixed unit connected to the frame body; a movable unit that can be displaced in a predetermined direction relative to the fixed unit; and at least one elastic member, which maintains the position of the movable unit relative to the fixed unit in the predetermined direction by elasticity.

[0223] Then, if Fig.15 , Fig.16As shown, the light receiving unit substrate holding frame 103 is disposed opposite to the light receiving unit substrate 80 and is a frame in a shape avoiding the optical filter 3. On the light receiving unit substrate holding frame 103, the aperture unit forming member 89, that is, the aperture unit 89a is positioned.

[0224] Here, if the optical filter 3 can be directly mounted on the light receiving unit substrate holding frame 103, the opening 32a (see Figure 2 ) and the relative position of the aperture portion 89a on the XY plane is accurately determined, but the optical filter 3 is a component for substrate mounting and cannot be directly set on the light receiving portion substrate holding frame 103.

[0225] However, in this embodiment, the light receiving unit substrate 80 having the optical filter 3 and the light receiving unit substrate holding frame 103 determine their relative positions in a direction intersecting the central axis (optical axis CL) of the aperture unit 89a, i.e., in a direction intersecting the Z-axis direction, through the above-mentioned positioning mechanism 90.

[0226] With such a structure, the position of the aperture portion 89a is determined relative to the light receiving portion substrate holding frame 103, and the position of the light receiving portion substrate 80 having the optical filter 3 is also determined. Thus, even if the optical filter 3 is not directly provided on the light receiving portion substrate holding frame 103, it is possible to suppress the aperture portion 89a from interfering with the opening portion 32a of the optical filter 3 (see Figure 2 )’s position shift on the XY plane can obtain appropriate color measurement results.

[0227] In addition, in the present embodiment, the aperture section 89a is formed on the aperture section forming member 89, and the aperture section forming member 89 is positioned relative to the light receiving section substrate holding frame 103, but for example, an opening may be formed in the light receiving section substrate holding frame 103, and the opening functions as the aperture section. In this case, from the viewpoint of ensuring color measurement accuracy, it is particularly preferred that the light receiving section substrate holding frame 103 is subjected to black anodized aluminum plating to suppress light reflection.

[0228] In addition, as in the present embodiment, in a structure in which the aperture portion 89a is formed in the aperture portion forming member 89 and the aperture portion forming member 89 is positioned relative to the light receiving portion substrate holding frame 103, if the aperture portion forming member 89 is formed of a black resin material and the anodized aluminum plating treatment (alumite treatment) of the light receiving portion substrate holding frame 103 is omitted, the color measurement accuracy can be ensured and the cost increase of the device can be suppressed.

[0229] In addition, it is needless to say that other materials may be used as appropriate for the light receiving unit substrate holding frame 103 and the aperture unit forming member 89 .

[0230] In addition, the colorimetric device 1 has a long side direction, i.e., the Y-axis direction, and a short side direction, i.e., the X-axis direction, when viewed from the Z-axis direction, and the light receiving unit substrate 80 is formed in a shape extending along the long side direction Y. Furthermore, the optical filter 3 is arranged in the light receiving unit substrate 80 at a position Yc (see Fig.14 ) is biased to one side, that is, the position in the +Y direction. Then, the positioning mechanism 90 determines the relative position of the light receiving unit substrate 80 and the light receiving unit substrate holding frame 103 at a point in the +Y direction from the center position Yc in the Y-axis direction (positioning hole 80a and convex portion 103h). As a result, the positional relationship between the light receiving unit substrate holding frame 103 and the light receiving unit substrate 80, which is formed in a shape extending in the Y-long side direction, is determined at a position close to the optical filter 3, and the positional deviation of the aperture portion 89a and the optical filter 3 can be appropriately suppressed.

[0231] In addition, in the present embodiment, the positioning mechanism 90 is configured to include: a protrusion (convex portion 103h, convex portion 103j) provided on one of the light receiving unit substrate 80 and the light receiving unit substrate holding frame 103; and an engagement hole (positioning hole 80a, long hole 80d) provided on the other of the light receiving unit substrate 80 and the light receiving unit substrate holding frame 103, into which the protrusion engages. Specifically, in the present embodiment, the positioning mechanism 90 includes the positioning hole 80a and the convex portion 103h engaged therewith, and the long hole 80d and the convex portion 103h engaged therewith.

[0232] Thus, the positioning mechanism 90 can be configured at low cost.

[0233] In addition, in this embodiment, the mating hole is provided on the light receiving unit substrate 80 and the protrusion is provided on the light receiving unit substrate holding frame 103, but conversely, the protrusion may be provided on the light receiving unit substrate 80 and the mating hole may be provided on the light receiving unit substrate holding frame 103.

[0234] In addition, in the present embodiment, the light focusing member 87, which is a cylindrical member forming a path of light from the measurement object 200 toward the aperture section 89a, is provided on the light receiving section substrate holding frame 103. In other words, the light focusing member 87 is positioned on the light receiving section substrate holding frame 103. Thus, the relative position of the light focusing member 87 and the aperture section 89a on the XY plane is appropriately determined.

[0235] In this embodiment, the light receiving unit substrate holding frame 103 is made of aluminum and its surface is subjected to black anodized aluminum plating, thereby suppressing a decrease in colorimetric accuracy due to light reflection in the light receiving unit substrate holding frame 103 .

[0236] Then, in Figure 3In the figure, the colorimetric device 1 comprises: an internal unit 1a having an incident light processing unit 2; and a main frame 51, which covers the internal unit 1a and forms the outer shell of the device. The frame assembly 100 constituting the base of the internal unit 1a is formed by a plurality of frames formed by aluminum, and the main frame 51 is formed by aluminum and is anodized with aluminum.

[0237] In this way, the frame assembly 100 and the main frame body 51 are formed of aluminum, so the heat dissipation is good. In addition, since the main frame body 51 is subjected to anodized aluminum treatment, the heat dissipation of radiation can be improved. Through the above structure, the heat generated inside the device can be well released to the outside of the device, and then an appropriate color measurement result can be obtained.

[0238] In addition, in the present embodiment, the anodized aluminum treatment of the main frame body 51 is black anodized aluminum treatment, but the present invention is not limited to this.

[0239] In the present embodiment, the upper frame 52, the bottom first frame 53A, and the bottom second frame 53B are formed of a resin material, but they may be formed of aluminum. In addition, in this case, black anodized aluminum treatment or anodized aluminum treatment of other colors may be performed.

[0240] In addition, the frame assembly 100 has contact portions 101d and 101e (see FIG. 101 ) that are in contact with the main frame body 51 on the inner side of the main frame body 51. Figure 7 ). Thus, heat can be efficiently transferred from the frame assembly 100 to the main frame body 51.

[0241] In addition, in this embodiment, since the plurality of frames constituting the frame assembly 100 are also subjected to black anodized aluminum plating like the main frame 51, the radiation heat dissipation of the frame assembly 100 can be improved, and the heat generated inside the device can be released to the outside of the device more effectively. In addition, in this case, other colors of anodized aluminum plating can be used instead of black anodized aluminum plating.

[0242] Alternatively, the anodized aluminum treatment of the plurality of frames constituting the frame assembly 100 may be omitted.

[0243] The main frame 51 has a long side direction (Y-axis direction) and a short side direction (X-axis direction) in a plan view, and has a holding recess 51g (see FIG. Fig.31 ). As a result, the operability of the device is improved, and the surface area of ​​the side wall of the main frame body 51 is increased, thereby improving the heat dissipation.

[0244] In addition, if Figure 7As shown, the frame assembly 100 includes a battery holding portion 100a in a shape surrounding the battery 17. Thus, the heat generated from the battery 17 is efficiently transferred to the battery holding portion 100a and is well dissipated to the outside of the device.

[0245] The frame assembly 100 includes a movable frame 105 as a substrate holding portion that holds the light receiving portion substrate 80 provided with the incident light processing portion 2 , and the battery holding portion 100 a and the movable frame 105 are arranged at a distance in the Z-axis direction.

[0246] That is, the battery 17 and the light receiving portion substrate 80 are both heat sources. If the two are arranged in close positions, efficient heat dissipation may not be possible. However, as described above, the battery retaining portion 100a and the movable frame 105 are arranged at a distance in the Z-axis direction, so efficient heat dissipation can be achieved.

[0247] In addition, in the present embodiment, the frame fixing portion 105a of the movable frame 105 constituting the movable unit 1e is displaced in the Z-axis direction while contacting a contact portion (not shown) formed on the inner side of the main frame 51. Thus, the movable frame 105, i.e., the heat of the movable unit 1e is transferred to the main frame 51, and the heat is well released to the outside of the device through the main frame 51.

[0248] Next, refer to Fig.31 As described, a first corner C1 where the first wall W1 and the third wall W3 intersect, a second corner C2 where the first wall W1 and the fourth wall W4 intersect, a third corner C3 where the second wall W2 and the fourth wall W4 intersect, and a fourth corner C4 where the second wall W2 and the third wall W3 intersect are formed on the inner side of the battery retaining portion 100a.

[0249] When the battery 17 is cut along the XZ plane, the upper portion is formed into an arc shape, and the lower portion is formed into a shape in which the width is narrowed toward the first wall portion W1 in such a way as to expand the interval with the third wall portion W3 and the interval with the fourth wall portion W4. As a result, a gap S1 is formed between the first corner portion C1 and the battery 17, a gap S2 is formed between the second corner portion C2 and the battery 17, a gap S3 is formed between the third corner portion C3 and the battery 17, and a gap S4 is formed between the fourth corner portion C4 and the battery 17.

[0250] Furthermore, in the present embodiment, the screws Z1 for assembling the first battery holding frame 101 and the second battery holding frame 102 constituting the battery holding portion 100 a are arranged by utilizing the gap S2 .

[0251] Furthermore, screws Z9 for assembling the main frame body 51 and the horizontal portion 101 b of the first battery holding frame 101 are arranged by utilizing the gaps S3 and S4 .

[0252] As described above, since the screws related to the battery holding portion 100 a are arranged by utilizing the gap formed inside the battery holding portion 100 a , it is possible to suppress the size increase of the device due to the components of the battery holding portion 100 a .

[0253] In addition, in the present embodiment, the components of the battery holding portion 100 a are arranged using the gaps S2 , S3 , and S4 , but it is sufficient to use at least any one of the gaps S1 , S2 , S3 , and S4 .

[0254] In addition, the battery 17 is formed in a shape in which the width is reduced toward the first wall W1 so as to expand the interval with the third wall W3 and the interval with the fourth wall W4, as described above, so that the gaps S1 and S2 can be expanded. Moreover, since the screw Z1 is arranged by utilizing the gap S2 formed in this way, the enlargement of the device caused by the components of the battery holding portion 100a can be further suppressed.

[0255] In addition, the components of the battery holding portion 100 a are not limited to screws, and may be other components, for example, a connector for connecting the battery 17 . Fig.33 A colorimetric device 150 according to another embodiment is shown, and the same reference numerals are given to the same structures as those already described. Fig.33 In the colorimetric device 150 shown, a screw Z1 is arranged in the battery holding portion 151 using a gap S3 , and a screw Z9 is arranged in the gap S4 .

[0256] Furthermore, in this embodiment, the battery control substrate 70 is arranged at a position close to the battery holding portion 151, so that the first connector 17c connected to the first battery connector 72 enters the gap S1, that is, it is arranged using the gap S1. In addition, the second connector 17d connected to the second battery connector 73 also enters the gap S2, that is, it is arranged using the gap S2. With such a structure, it is possible to suppress the enlargement of the device.

[0257] In addition, Fig.33 In the illustrated structure, the first battery connector 72 and the second battery connector 73 do not enter the gaps S1 and S2 , respectively, but may be configured to enter the gaps S1 and S2 .

[0258] In addition, the structure configured using at least any one of the gaps S1, S2, S3, and S4 may be any one of a connector for connecting the battery 17, screws for assembling multiple frames constituting the battery retaining portion 100a, and screws for assembling the main frame 51 and the battery retaining portion 100a, or any two of them, or all of them.

[0259] In addition, the structure configured relative to a gap may be any one of a connector connecting the battery 17, screws for assembling a plurality of frames constituting the battery retaining portion 100a, and screws for assembling the main frame 51 and the battery retaining portion 100a, or any two of them, or all of them.

[0260] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention described in the claims, and such modifications are naturally included in the scope of the present invention.

[0261] For example, in the above-mentioned embodiment, the colorimetric device 1 has the battery 17 built in, but the battery 17 may be detachable, that is, the colorimetric device 1 may not have the battery 17 built in. In this case, the battery 17 may be a primary battery that is not repeatedly charged and discharged.

[0262] In addition, in the present embodiment, the incident light processing unit 2 is configured to include an optical filter 3 and a light receiving unit 4. The optical filter 3 is a wavelength-variable Fabry-Perot etalon that transmits a predetermined wavelength component in the incident light, but is not limited thereto. For example, as a spectroscopic method, a spectroscopic method using a diffraction grating may also be used. In addition, as a colorimetric principle, a device structure using a stimulus value direct reading method that directly measures three stimulus values ​​that are the basis of color may also be used.

[0263] In addition, although LED is used as the light emitting element used in the light emitting unit 9 in the present embodiment, the present invention is not limited to this, and for example, a xenon lamp may be used.
