The color measurement device is characterized by including: a substrate including an optical filter that processes light from a measurement target; an aperture portion that reduces an amount of light from the measurement target toward the optical filter; a frame that is disposed opposite to the substrate, fixes the substrate, and is shaped to avoid the optical filter, and that positions the aperture portion at a position opposite to the optical filter; and a positioning mechanism that determines a relative position of the substrate and the frame in a direction that intersects a center axis of the aperture portion.

Description

Technical Field

[0001] This invention relates to a colorimetric apparatus that measures color based on light emitted from the object being measured. Background Technology

[0002] Previously, colorimetric devices that measure color based on light emitted from the object being measured were known. These devices, for example, involve incident light from the object onto a spectrophotometer, extracting a specified wavelength component through the spectrophotometer, and then receiving the light through a photodiode. Color measurement is performed by detecting the voltage output from the photodiode. In particular, such colorimetric devices are sometimes also referred to as spectrophotometers.

[0003] In patent document 1 Figure 3 An optical module is disclosed, which is configured to allow light to enter a beam splitter through an opening in a frame, extract a specified wavelength component using the beam splitter, and receive the light using a light-receiving element.

[0007] In the structure described in Patent Document 1 above, the opening provided in the frame functions as an aperture portion that reduces the amount of light incident on the beam splitter. Furthermore, the light outlet in the beam splitter is also formed in an open shape, arranged such that the central axis of the opening in the frame is aligned with the central axis of the light outlet in the beam splitter.

[0008] However, in terms of device structure, when it is not possible to directly install a spectrometer filter on the frame, the central axis of the opening that functions as the aperture part deviates from the central axis of the light outlet in the spectrometer filter, which may have a potential adverse effect on the measurement results. Summary of the Invention

[0009] The colorimetric apparatus of the present invention, which addresses the aforementioned problems, is characterized by comprising: a substrate having an optical filter for processing light emitted from a measurement object; an aperture portion for reducing the amount of light from the measurement object toward the optical filter; a frame being disposed opposite to the substrate and for fixing the substrate thereto, and having a shape that avoids the optical filter, with the aperture portion positioned at a position opposite to the optical filter; and a positioning mechanism for determining the relative positions of the substrate and the frame in a direction intersecting the central axis of the aperture portion.

Detailed Implementation

[0045] The present invention will now be described in brief.

[0046] The colorimetric apparatus according to the first method is characterized by comprising: a substrate having an optical filter for processing light emitted from the object being measured; an aperture portion for reducing the amount of light from the object being measured toward the optical filter; a frame being disposed opposite to the substrate and for fixing the substrate, and having a shape that avoids the optical filter, and the aperture portion being positioned at a position opposite to the optical filter; and a positioning mechanism for determining the relative positions of the substrate and the frame in a direction intersecting the central axis of the aperture portion.

[0047] According to this method, the position of the aperture portion and the position of the optical filter are defined relative to the frame. Therefore, even in a structure where the optical filter is not directly mounted on the frame, positional misalignment between the aperture portion and the optical filter can be suppressed, and appropriate colorimetric results can be obtained.

[0048] The second approach is characterized in that, based on the first approach, the frame of the housing of the device has a long side direction and a short side direction when viewed from the direction of the central axis, the substrate is formed to extend along the long side direction, the optical filter is disposed on the substrate at a position offset to one side from the center position of the substrate in the long side direction, and the positioning mechanism determines the relative position at at least one location on the side from the center position in the long side direction.

[0049] According to this method, the positional relationship between the substrate forming a shape extending along the long side and the frame is determined to be close to the optical filter, which can appropriately suppress the positional offset between the aperture portion and the optical filter.

[0050] The third approach is characterized in that, based on the first or second approach, the positioning mechanism is configured to include: a protrusion disposed on one of the substrate and the frame; and a fitting hole disposed on the other of the substrate and the frame for the protrusion to fit into.

[0051] According to this method, the positioning mechanism can be constructed at low cost.

[0052] The fourth method is characterized by having a cylindrical member, based on any one of the first to third methods, forming a light path from the measured object toward the aperture portion, the cylindrical member being positioned within the frame.

[0053] According to this method, a cylindrical member is provided to form a path of light from the measured object toward the aperture portion. The cylindrical member is positioned in the frame, and thus the relative position of the cylindrical member and the aperture portion is appropriately determined.

[0054] The fifth method is characterized in that, based on any of the first to fourth methods, the frame is formed of aluminum and the surface is treated with black anodized aluminum plating.

[0055] According to this method, since the frame is formed of aluminum and its surface is treated with black anodized aluminum plating, the reduction in colorimetric accuracy caused by light reflection at the frame can be suppressed.

[0056] The sixth embodiment is characterized in that, based on any one of the first to fifth embodiments, the colorimetric device has an internal unit comprising: an opening forming member disposed at the bottom of the device and having an opening for taking in light emitted from the object being measured into the device; a substrate; and a frame. The internal unit further comprises: a fixed unit connected to the opening forming member; a movable unit comprising the substrate and the frame and capable of displacement relative to the fixed unit in a first direction along the central axis; and at least one elastic member that elastically maintains the position of the movable unit relative to the fixed unit in the first direction.

[0057] According to this method, the internal unit of the device includes: the fixed unit; and the movable unit, which is a unit having the base plate and the frame, and is capable of displacement relative to the fixed unit in a first direction along the central axis, and the movable unit achieves impact buffering through the elastic member.

[0058] Furthermore, the movable unit includes the incident light processing section, thus protecting the incident light processing section from impacts caused by falling or other reasons.

[0059] In addition, the movable unit also includes the aperture section in addition to the incident light processing section. The incident light processing section and the aperture section are integrally displaced, so the relative position of the incident light processing section and the aperture section can be maintained, and the reduction of color measurement accuracy can be suppressed.

[0060] Furthermore, since an impact buffer structure is adopted relative to the first direction, it is possible to suppress the increase in size and cost of the device compared to a structure in which the impact buffer structure is set in a direction with high impact resistance.

[0061] In addition, the total weight of the internal units of the above-mentioned device is not applied to the elastic member, i.e., the impact buffer structure; only the weight of the movable unit is applied to the elastic member. Therefore, it is also possible to suppress the increase in the size and cost of the elastic member, and thus suppress the increase in the size and cost of the device.

[0062] The seventh method is characterized in that, based on the sixth method, the fixing unit comprises: a first unit connected to the opening forming member; a second unit located on a side away from the opening forming member relative to the first unit in the first direction, connected to the first unit in a state of being spaced apart from the first unit along the first direction; and a guide shaft extending along the first direction in the interval between the first unit and the second unit, wherein the movable unit comprises a guided portion located between the first unit and the second unit and guided by the guide shaft.

[0063] According to this method, a device for displacing the movable unit in the first direction can be obtained with a simple structure and low cost.

[0064] The eighth method is characterized in that, based on the seventh method, the elastic member is arranged between the first unit and the guided portion, and between the second unit and the guided portion, with its free length shortened in the first direction.

[0065] According to this method, the elastic member is positioned between the first unit and the guided portion, and between the second unit and the guided portion, with its free length shortened in the first direction. Therefore, the elastic member is always compressed, thereby stabilizing the position of the movable unit in the first direction and making it difficult for the position of the elastic member in the direction intersecting the first direction to shift.

[0066] The ninth method is characterized in that, based on any of the first to eighth methods, the optical filter is a wavelength-variable Fabry-Perot etalon that allows a specified wavelength component of the incident light to pass through.

[0067] According to this method, in the structure of the optical filter being a wavelength-variable Fabry-Perot etalon that allows a specified wavelength component of the incident light to pass through, the effect of any of the first to eighth methods described above can be obtained.

[0068] The present invention will now be described in detail.

[0069] In addition, the XYZ coordinate system shown in each figure is an orthogonal coordinate system, with the XY plane being the horizontal plane and the YZ plane being the vertical plane.

[0070] Furthermore, 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. This first direction is parallel to the optical axis CL, which will be described later. The Y-axis direction is orthogonal to the first direction and becomes the long side direction of the device when viewed from the Z-axis direction. The X-axis direction is orthogonal to the Y-axis direction and becomes the short side direction of the device when viewed from the Z-axis direction.

[0071] In this specification, the structure of the color measuring device 1 is described with the bottom surface 50f placed on a mounting surface parallel to the horizontal plane and the long side of the color measuring device 1 along the Y-axis direction.

[0072] Overall structure of colorimetric device 1

[0073] First, refer to Figure 1 and Figure 2 This paper mainly provides an overview of the overall structure of the colorimetric device 1 in this embodiment from a functional perspective.

[0074] The colorimetric device 1 has a structure for measuring color based on light emitted from the object being measured 200. Examples of light emitted from the object being measured 200 include light reflected from the object being measured 200 and light emitted by the object being measured 200 itself.

[0075] The colorimetric device 1 includes a bandpass filter 7, an optical filter 3, a light receiving unit 4, an electrostatic capacitance detection unit 6, a light emitting unit 9, an MCU (Micro Controller Unit) 10, a wired IF (Interface) 12, a wireless communication unit 13, an operation unit 14, a display unit 15, a battery control unit 16, and a battery 17.

[0076] In addition, the optical filter 3 and the light receiving part 4 constitute the incident light processing part 2 for processing the incident light emitted from the measurement object 200.

[0077] The bandpass filter 7 allows light in the visible light region, such as 380 nm to 720 nm, to pass through incident light from the measurement object 200, while blocking light in the ultraviolet and infrared regions. Thus, light in the visible light region is incident on the optical filter 3. Furthermore, light from the measurement object 200 is delivered to the bandpass filter 7 through the opening 21a (described later). Figure 5 The sample is taken into the device and then measured through window 87a (refer to...). Figure 5 ) Reach the bandpass filter 7.

[0078] Optical filter 3 selectively allows any wavelength component to pass through visible light that has passed through bandpass filter 7. The light transmitted through optical filter 3 is incident on photodiode 4a, which is an example of a light-receiving element, and is processed by light-receiving unit 4 equipped with photodiode 4a. Light-receiving unit 4 converts the intensity of the received light into a voltage value, then converts the voltage value into a digital signal, and outputs the digital signal to MCU 10. Colorimetric device 1, by repeatedly performing wavelength selection based on optical filter 3 and acquiring the light intensity using light-receiving unit 4, is able to measure the spectrum of the object to be measured 200.

[0079] Here, refer to Figure 2 The structure of the optical filter 3 will be described. In this embodiment, the optical filter 3 is a wavelength-variable Fabry-Perot etalon that allows a specified wavelength component of the light incident from the measurement object 200 to pass through. It is a wavelength filter that utilizes multiple interference from two opposing reflective surfaces.

[0080] exist Figure 2 In the optical filter 3, a wavelength-variable interference filter 45 is included, which is built into the interior of an outer casing consisting of a first glass component 30, a second glass component 31, and a housing 32.

[0081] The housing 32 is joined to the first glass component 30 and the second glass component 31 respectively by bonding components 33 such as low-melting-point glass and epoxy resin. Furthermore, the wavelength-variable interference filter 45 and the housing 32 are fixed by a fixing material 34 such as an adhesive. The electrodes 36 on the outer surface of the housing 32 and the wavelength-variable interference filter 45 are connected by lead wire bonding 35 and wiring within the housing 32.

[0082] The wavelength-variable 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. Reflectors 39 are formed on the base substrate 37 and the diaphragm substrate 38, respectively. The outermost surface of each opposing reflector 39 is formed of a conductor. Furthermore, the electrostatic capacitance between the opposing reflectors 39 is measured by an electrostatic capacitance detection unit 6 (see reference 6). Figure 1 The electrostatic capacitance detection unit 6 consists of a CV (Capacitance to Voltage) converter, which converts the detected electrostatic capacitance into a voltage value, and then into a digital value, which is then sent to the MCU10.

[0083] The distance between the opposing reflectors 39 is controlled by an electrostatic actuator, which is formed by a fixed electrode 40 and a movable electrode 41 that are concentrically arranged when viewed from the Z-axis direction.

[0084] When a voltage is applied between the fixed electrode 40 and the movable electrode 41, an electrostatic force generates a force that attracts the fixed electrode 40 and the movable electrode 41 to each other. At this time, by deforming the concentrically shaped diaphragm portion 42, the reflector 39 of the diaphragm substrate 38 is pulled closer to the base substrate 37, and the distance between the opposing reflectors 39 is controlled. Furthermore, the wavelength of light transmitted through the wavelength-variable interference filter 45 is selected corresponding to the distance between the opposing reflectors 39.

[0085] During spectrophotometry, light from the object being measured 200 is incident on the optical filter 3 along the optical axis CL from the side of the second glass member 31 to the side of the first glass member 30. Furthermore, the optical axis CL is parallel to the Z-axis direction, passing through the opening 21a (see reference). Figure 5 ), Measurement window 87a (reference) Figure 5 The center line of the wavelength-variable interference filter 45 and the photodiode 4a. In particular, the opening 21a, the measuring window 87a, and the wavelength-variable interference filter 45 are circular when viewed from the Z-axis direction, and the optical axis CL passes through their center. In addition, the area below the optical axis CL is sometimes referred to as the center position CL.

[0086] Furthermore, the light incident on the optical filter 3 interferes between the opposing reflectors 39, and light of a wavelength selected corresponding to the distance between the opposing reflectors 39 passes through the wavelength-variable interference filter 45. The light passing through the wavelength-variable interference filter 45 passes through the opening 32a of the housing 32 through the first glass member 30 and toward the light-receiving part 4. The opening 32a of the housing 32 is a circular opening centered on the optical axis CL.

[0087] The above describes the structure of optical filter 3. Furthermore, as mentioned above, optical filter 3 is a structure that selects the wavelength of transmitted light according to the distance between it and the opposing mirror 39 in the wavelength-variable interference filter 45. Therefore, it is not resistant to impacts in the Z-axis direction; that is, measurement accuracy easily decreases with impacts in the Z-axis direction. On the other hand, it can be said that optical filter 3 is a structure relatively strong against impacts in directions intersecting the Z-axis.

[0088] return Figure 1 MCU10 is a microprocessor-based control device with a built-in memory that stores various programs and data required for the control of color measuring device 1.

[0089] MCU10 will refer to Figure 2The control information required for driving the electrostatic actuator, which is configured by the fixed electrode 40 and the movable electrode 41 facing each other, is sent to an amplifier (not shown), from which a predetermined driving voltage is supplied to the optical filter 3. Furthermore, the MPU10 compares 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 this comparison.

[0090] The light-emitting unit 9 emits light for measurement toward the object being measured 200. The light-emitting unit 9 is composed of multiple light-emitting elements with different wavelength distributions, specifically multiple LEDs. The MCU 10 controls the lighting and extinguishing of the light-emitting unit 9.

[0091] The wired IF12 and wireless communication unit 13 are components for communicating with external devices. For example, USB (Universal Serial Bus) can be used for communication via the wired IF12. Similarly, Bluetooth can be used for the wireless communication unit 13. USB and Bluetooth are registered trademarks. The MCU 10 transmits various data to and receives various data from external devices via the wired IF12 or wireless communication unit 13. Furthermore, the colorimetric device 1 can charge the battery 17 by receiving power from an external device via the wired IF12.

[0092] The operation unit 14 consists of a power button and various operation setting buttons, and sends operation-related signals to the MCU 10. The operation unit 14 will be further explained later.

[0093] As an example, the display unit 15 is composed of a liquid crystal panel, which displays various information such as the user interface for setting color measurement conditions and color measurement results based on the signals sent from the MCU 10.

[0094] The shutter sensor 114, which sends a detection signal to the MCU10, is a sensor used to detect the position of the shutter unit 110, which will be described later.

[0095] In this embodiment, battery 17 is a lithium-ion secondary battery that supplies power to various components in the colorimetric device 1 that require electricity. Components that receive power from battery 17 include the incident light processing unit 2, which will be described later. Battery control unit 16 performs various controls, such as charging control of battery 17.

In this embodiment, the upper frame 52, the bottom first frame 53A, and the bottom second frame 53B are formed of resin material, and the main frame 51 is formed of aluminum. However, the main frame 51 may also be formed of other metals or resin materials instead of aluminum.

[0103] An operation section 14 and a display section 15 are arranged on the upper surface 50e of the device body 50 along the Y-axis direction.

[0104] The operation unit 14 is configured to include a power button 55, a confirmation button 54, a return button 56, and a cross button 60. The cross button 60 consists of an up button 61, a down button 62, a left button 63, and a right button 64. In the color measuring device 1 of this embodiment, all operation buttons are arranged on the upper surface 50e and are gathered in the operation unit 14.

[0105] The power button 55 is used to turn the power to the colorimeter device 1 on / off. The confirmation button 54 is used to confirm various settings displayed on the display unit 15, i.e., to determine the colorimeter conditions, and also to perform the colorimeter measurement. The confirmation button 54 is circular when viewed from the Z-axis direction.

[0106] The area around the confirmation button 54 is configured as a ring-shaped light-emitting part 59, and the light-emitting color and light-emitting state change according to the state of the device.

[0107] The back button 56 is used to return to the previous state in the user interface displayed on the display unit 15, and it is also used to cancel the execution of the operation.

[0108] The cross button 60 is used to select various items in the user interface displayed on the display unit 15.

[0109] The display unit 15 displays various information such as color measurement results. In this embodiment, the display unit 15 is composed of a liquid crystal display 67 (see also [reference 15]). Figure 9 Hereinafter, the liquid crystal display 67 will be referred to as LCD67. A display cover 57, which is a transparent component, is provided on the upper part of the LCD67, and a portion of the upper surface 50e is formed by the display cover 57.

[0110] In this embodiment, as well as Figure 9 As shown, the upper surface 50e is configured such that there are almost no steps between the upper surface of the display cover 57 and the upper surface of the operation section 14, thus the upper surface 50e is configured as a flat surface with almost no steps. However, the upper surface of the confirmation button 54 is slightly concave, and is shaped to fit the fingertip of the user pressing the confirmation button 54.

[0111] like Figure 4 , Figure 5 As shown, a shutter unit 110 is provided on the bottom surface 50f. Figure 4 This shows the shutter unit 110 in the closed position. Figure 5 The shutter unit 110 is shown in the open position. The shutter unit 110 can be displaced between the closed and open positions by sliding along the Y-axis. Furthermore, the shutter unit 110 is configured to maintain the closed and open positions by the spring force of a spring (not shown).

[0112] The shutter unit 110 includes a shutter holding member 111 and a connecting rod member 113.

[0113] By from Figure 4 The shutter unit 110 is in a state of opening, such as Figure 5As shown, opening 21a and measuring window 87a are exposed. Opening 21a and measuring window 87a open in the -Z direction. Opening 21a and measuring window 87a are circular openings when viewed from above. Furthermore, the term "opening" here refers to the intake of light, for example, it means that a transparent glass plate can be installed.

[0114] An opening 21a is formed on an opening forming member 21 provided at the bottom of the device, and a measuring window 87a is formed on a focusing member 87 located in the +Z direction relative to the opening forming member 21. The opening forming member 21 is formed in a shape that extends integrally throughout the bottom of the device.

[0115] The measuring light emitted from the light-emitting unit 9, such as Figure 10 As shown by arrow a on the inner side of the central opening 21a, light is emitted from the opening 21a toward the measurement object 200 between the cylindrical portion 87b of the focusing member 87 and the opening forming member 21. Then, light from the measurement object 200 is captured from the opening 21a and drawn into the device, and then incident on the bandpass filter 7 through the measurement window 87a. The 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.

[0116] In addition, such as Figure 6 As shown, the optical axis CL is aligned with the central axis of the opening 21a and the measuring window 87a. Furthermore, in Figure 6 In the diagram, line VCL is a line parallel to the Y-axis and passes through the optical axis CL when viewed from the Z-axis. Similarly, line HCL is a line parallel to the X-axis and passes through the optical axis CL when viewed from the Z-axis.

[0117] In this embodiment, the optical axis CL is aligned with the center of the confirm button 54 in the XY plane, and also with the center of the cross button 60.

[0118] The power button 55 and the return button 56 are arranged symmetrically on the left and right sides of the straight line VCL.

[0119] Next, as Figure 3 As shown, a wired IF12 is provided on the front surface 50a of the device body 50. By providing the wired IF12 on the front surface 50a, even when the colorimetric device 1 is used with the cable connected to the wired IF12, the cable is not present on the user side and is unlikely to become an obstacle to operation.

[0120] In addition, such as Figure 9 As shown, an opening 50m is formed on the rear surface 50d of the device body 50, and a reset switch 71 is provided inside the opening 50m. The reset switch 71 is a switch used to return the various settings of the colorimetric device 1 to their initial state.

[0121] like Figure 3 , Figure 31 As shown, a gripping portion 50g is formed on the right side 50b and left side 50c of the device body 50. The gripping portion 50g is composed of a recess 51g formed on the right wall portion 51b and the left wall portion 51c of the main frame 51, respectively. The recess 51g is formed by a curved surface that faces the center of the device body 50 in the X-axis direction along the -Z direction.

[0122] By setting the gripping part 50g, the user can easily and reliably grip the main body 50 of the device.

[0123] Next, in Figure 5 In this device, the sides surrounding the bottom surface are formed by a first bottom frame 53A and a second bottom frame 53B. Sides E1 in the +X direction and E2 in the -X direction are formed as straight lines along the Y-axis, and similarly, sides E3 in the +Y direction and E4 in the -Y direction are formed as straight lines along the X-axis. This allows the gauge to abut against each side, enabling the colorimetric device 1 to slide along the gauge while performing measurements. For the reasons stated above, the first bottom frame 53A and the second bottom frame 53B are preferably made of a resin material with low frictional resistance; as an example, POM (polyoxymethylene) can be used.

[0124] substrate structure of colorimetric device 1

[0125] Next, the substrate structure of the colorimetric device 1 will be described.

[0126] Figure 7 , Figure 8 The internal unit 1a of the device shown is a component body disposed inside the main frame 51, and is constructed by assembling batteries, multiple circuit boards, etc., in the frame assembly 100, which is an assembly of multiple frames. However, in Figure 7 , Figure 8 The panel substrate 65 at the top is omitted from the diagram.

[0127] like Figure 9 As shown, multiple circuit boards are arranged sequentially from top to bottom as follows: a panel substrate 65 (as the "fourth circuit board"), a battery control substrate 70 (as the "third circuit board"), a light-receiving substrate 80 (as the "first circuit board"), and a light-emitting substrate 85 (as the "second circuit board"). These multiple circuit boards are arranged in an overlapping manner with intervals along the Z-axis. A battery 17 is disposed between the panel substrate 65 and the battery control substrate 70 in the Z-axis direction.

[0128] The following describes each circuit board and its surrounding structure. Additionally, the surface in the +Z direction of each circuit board will sometimes be referred to as the "top surface," and the surface in the -Z direction as the "bottom surface."

[0129] like Figure 9 , Figure 11 As shown, the panel substrate 65 has an LCD connection portion 66 on its upper surface. The LCD 67 is connected to the LCD connection portion 66 via a cable 67a.

[0130] Furthermore, on the upper surface of the panel substrate 65, at positions corresponding to the operation buttons constituting the aforementioned operation section 14, contacts for detecting the pressing of each operation button are provided. Figure 9 In the attached drawing, reference numeral 54a indicates a contact point located at the position corresponding to the OK button 54. Reference numerals 61a and 62a are contacts located at the positions corresponding to the up button 61 and the down button 62, respectively. Additionally, in... Figure 11 In the attached drawing, reference numeral 56a indicates a contact point located at the position corresponding to the return button 56, and reference numeral 63a indicates a contact point located at the position corresponding to the left button 63. Additionally, Figure 9 and Figure 11 Contacts not shown, namely the contacts corresponding to the right button 64 and the power button 55, are also provided on the upper surface of the panel substrate 65.

[0131] In addition, such as Figure 11 As shown, a sheet 69 is provided between each contact point provided on the upper surface of the panel substrate 65 and each button constituting the operation section 14. The sheet 69 provides a waterproof function for each contact point provided on the upper surface of the panel substrate 65, maintaining the function of each contact point. The sheet 69 can be, for example, a rubber sheet.

[0132] In addition, such as Figure 9 As shown, a wireless communication unit 13, serving as a communication module, is provided on the lower surface of the panel substrate 65. The wireless communication unit 13 is configured to communicate via a battery holding portion 100a (described later). Figure 7 The cut portion 100b and such Figure 9 It enters the inside of the battery holding section 100a as shown.

[0133] In addition, the panel substrate 65 is connected to the light-receiving substrate 80 described later via a cable (not shown).

[0134] Next, the battery control board 70 implements the battery control unit 16 (see reference). Figure 1 The function of ). For example Figure 7 , Figure 13 As shown, the battery control board 70 has a reset switch 71 and a wired IF12 on its upper surface. Additionally, the battery control board 70 has a first battery connector 72 on its upper surface. Figure 7As shown, the first connector 17c, mounted on the first battery cable 92 extending from the battery 17, engages with the first battery connector 72. Additionally, as... Figure 8 As shown, the battery control board 70 has a second battery connector 73 on its upper surface. The second connector 17d, which is mounted on the second battery cable 93 extending from the battery 17, engages with the second battery connector 73.

[0135] Furthermore, a battery control circuit (not shown) is provided on the upper surface of the battery control board 70.

[0136] In addition, the battery control board 70 is connected to the light-receiving board 80 and the light-emitting board 85 via a connection mechanism not shown, thereby supplying power from the battery 17 to each board.

[0137] Next, as Figure 9 , Figure 10 , Figure 13 As shown, a photodiode (PD) substrate 5 is formed on the upper surface of the light-receiving substrate 80. A photodiode 4a is provided on the lower surface of the PD substrate 5. The PD substrate 5 constitutes the light-receiving portion 4 (see reference). Figure 1 The circuit board of the PD substrate. That is, the PD substrate 5 constitutes the incident light processing unit 2 (refer to) for processing incident light. Figure 1 ).

[0138] In addition, such as Figure 14 As shown, the light-receiving substrate 80 has an optical filter 3 on its lower surface.

[0139] In addition, various electronic components are provided on the light-receiving substrate 80, including MCU10 (see reference). Figure 1 ), constituting the electrostatic capacitance detection unit 6 (refer to Figure 1 The CV converter, the DC / DC converter that converts the voltage of the battery 17, the amplifier that adjusts the output from the DC / DC converter under the control of the MCU 10 and supplies it to the optical filter 3, and the temperature sensor for detecting the temperature around the optical filter 3, etc.

[0140] Next, as Figure 12 As shown, a plurality of light-emitting elements 86 are disposed on the lower surface of the light-emitting substrate 85. The light-emitting elements 86 constitute the light-emitting section 9 (see reference). Figure 1 The multiple light-emitting elements 86 are composed of light-emitting elements with different wavelength distributions. The light-emitting substrate 85 has a hole through which the cylindrical portion 87b of the light-concentrating member 87 is inserted, and multiple light-emitting elements 86 are arranged around the hole.

[0141] Frame structure of internal units of the device

[0142] Next, the frame assembly 100 that constitutes the base of the internal unit 1a of the device will be described.

[0143] like Figure 7 , Figure 8 , Figures 21-24 As shown, the frame assembly 100 is configured to include a first battery holding frame 101, a second battery holding frame 102, a light-receiving substrate holding frame 103, a light-emitting substrate holding frame 104, a movable frame 105, and a bottom frame 106. In this embodiment, each frame is assembled by screws.

[0144] In this embodiment, all the frames are formed by bending metal materials; for example, aluminum is used. Alternatively, the frames can be manufactured by die casting or the like, instead of bending metal materials.

[0145] The following describes each frame in turn. The first battery holding frame 101 is a frame constituting the battery holding part 100a, and has: a first vertical part 101a, which forms a frame surface parallel to the YZ plane; a horizontal part 101b, which forms a frame surface parallel to the XY plane; and a second vertical part 101c, which forms a frame surface parallel to the YZ plane.

[0146] Among them, such as Figure 9 As shown, the horizontal portion 101b supports the panel substrate 65 from below. The panel substrate 65 is fixed to the horizontal portion 101b by screws (not shown). The panel substrate 65 is in surface contact with the horizontal portion 101b, thereby transferring heat from the panel substrate 65 to the horizontal portion 101b, i.e., the first battery holding frame 101.

[0147] Additionally, at the end of the horizontal section 101b in the +Y direction, such as Figure 9 As shown, the battery limiting part 101f is formed to extend from the horizontal part 101b in the -Z direction. The battery limiting part 101f restricts the movement of the battery 17 in the +Y direction.

[0148] Next, the second battery retaining frame 102 together with the first battery retaining frame 101 forms the battery retaining part 100a. Screws Z1 and Z2 are screws for assembling the first battery retaining frame 101 and the second battery retaining frame 102.

[0149] The second battery retaining frame 102 includes: a battery support portion 102a, forming a frame surface parallel to the XY plane; a first vertical portion 102b, forming a frame surface parallel to the YZ plane; and a second vertical portion 102c, forming a frame surface parallel to the YZ plane.

[0150] The battery support portion 102a supports the battery 17 from below. The bottom surface of the battery 17 is in contact with the surface of the battery support portion 102a, thereby transferring the heat of the battery 17 to the battery support portion 102a, i.e., the battery holding portion 100a.

[0151] In addition, a battery positioning part 102d is formed on the battery support part 102a by bending it up, thereby determining the position of the battery 17 in the X-axis direction.

[0152] The first vertical portion 102b is located in the -X direction relative to the first vertical portion 101a of the first battery holding frame 101 and is in contact with the surface of the first vertical portion 101a. Similarly, the second vertical portion 102c is located in the -X direction relative to the second vertical portion 101c of the first battery holding frame 101 and is in contact with the surface of the second vertical portion 101c.

[0153] Thus, the battery holding part 100a is configured to surround the battery 17 by means of a first battery holding frame 101 and a second battery holding frame 102.

[0154] In the battery holding section 100a, such as Figure 9 As shown, an elastic member 28 is provided between the horizontal portion 101b and the battery 17. The elastic member 28 is also located between the +Y direction end (first end 17a) of the battery 17 and the battery retaining portion 101f. Furthermore, the elastic member 28 is also located between the -Y direction end (second end 17b) 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 within the battery holding portion 100a is restricted. For example, a sponge can be used as the elastic member 28.

[0155] Here, refer to Figure 31 The battery support portion 102a forms a first wall portion W1 that supports the battery 17 from below. Additionally, the horizontal portion 101b, opposite the battery support portion 102a, forms a second wall portion W2 located above the battery 17. Furthermore, 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 that clamps the battery 17. The third wall portion W3 is composed of a second vertical portion 101c and a second vertical portion 102c, and the fourth wall portion W4 is composed of a first vertical portion 101a and a first vertical portion 102b.

[0156] In addition, Figure 31 In the battery holding part 100a, a first corner C1 where the first wall W1 intersects with the third wall W3, a second corner C2 where the first wall W1 intersects with the fourth wall W4, a third corner C3 where the second wall W2 intersects with the fourth wall W4, and a fourth corner C4 where the second wall W2 intersects with the third wall W3 are formed on the inner side.

[0157] Next, refer toFigure 7 The internal unit 1a of the device includes a fixed unit 1b and a movable unit 1e. The fixed unit 1b is a member 21 that forms relative to the main frame 51 and the opening (see reference). Figure 9 The fixed unit 1b and the movable unit 1e are unit bodies that can be displaced relative to the fixed unit 1b in the Z-axis direction.

[0158] The fixing unit 1b includes: a first unit 1c, which is connected to the opening forming member 21; and a second unit 1d, which is located on the side away from the opening forming member 21 in the Z-axis direction relative to the first unit 1c, and is connected to the first unit 1c in a state of being spaced apart from the first unit 1c in the Z-axis direction.

[0159] The second unit 1d consists of a battery holder 100a and a battery 17. The first unit 1c consists of a bottom frame 106.

[0160] Figure 25 The frame assembly constituting the fixing unit 1b is formed by connecting the battery holding part 100a and the bottom frame 106.

[0161] More specifically, the bottom frame 106 is formed to have a base portion 106a that forms a frame surface parallel to the YZ plane and a guide support portion 106b that forms a frame surface parallel to the XY plane.

[0162] Two guide shafts 107 are fixed to the guide support portion 106b. In this embodiment, the guide shaft 107 is a metal shaft extending along the Z-axis direction and is fixed to a hole (not shown) formed in the guide support portion 106b by riveting. The guide shaft 107 extends from the guide support portion 106b in the +Z direction to an end that is approximately coplanar with the upper surface of the battery support portion 102a. A hole (not shown) is formed in the battery support portion 102a for the guide support portion 106b to pass through.

[0163] Three fixing screws Z6 are formed on the guide support portion 106b (see reference). Figure 24 The threaded hole (not shown) is secured by three screws Z6 in the state of inserting the tube 108, thereby connecting the battery holder 100a to the bottom frame 106.

[0164] In this embodiment, the tube 108 is a metal tube, which defines the distance between the battery holder 100a and the bottom frame 106 in the Z-axis direction. Furthermore, heat transfer between the battery holder 100a and the bottom frame 106 is achieved using the tube 108 and the screw Z6.

[0165] In this way, the battery holding part 100a and the bottom frame 106 are connected with a gap in the Z-axis direction, that is, the first unit 1c and the second unit 1d are connected with a gap in the Z-axis direction.

[0166] Furthermore, in this specification, the term "threaded hole" refers to a hole with a spiral groove formed for fixing a screw, unless otherwise specified. The term "screw through hole" refers to a hole without a spiral groove, which is only used for screw insertion, unless otherwise specified.

[0167] Next, in the bottom frame 106, a bent portion 106c is formed extending from the -Y direction end of the base 106a in the -X direction, and a connecting portion 106e is formed extending from the bent portion 106c in the +Y direction. Similarly, a bent portion 106d is formed extending from the +Y direction end of the base 106a in the -X direction, and two connecting portions 106f are formed extending from the bent portion 106d in the -Y direction (see also...). Figure 23 ).

[0168] Furthermore, the opening forming member 21 is threadedly fixed to the connecting portions 106e and 106f. For example, in Figure 9 The screw indicated by reference numeral Z14 in the accompanying drawings is the screw that secures the opening forming member 21 to the connecting portion 106e. In this embodiment, screw Z14 secures both the bottom first frame 53A and the opening forming member 21 to the connecting portion 106e. Furthermore, the end of the opening forming member 21 in the +Y direction is secured to the connecting portion 106f by a screw (not shown).

[0169] In this embodiment, the opening forming member 21 is made of a metallic material, for example, aluminum. Thus, heat from the bottom frame 106 is transferred to the opening forming member 21. The bottom frame 106 is connected via a tube 108 and screw Z6 (see reference). Figure 24 It is connected to the battery holding part 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.

[0170] Alternatively, the opening forming member 21 can also be formed of resin material.

[0171] Next, regarding the structure of the movable unit 1e that constitutes the internal unit 1a of the device, it is mainly referred to Figure 12 , Figure 13 , Figures 26-29 Furthermore, other accompanying drawings may be used for explanation as needed.

[0172] exist Figure 12 and Figure 13In the movable unit 1e, the base is composed of a movable frame 105, a light-receiving substrate holding frame 103 and a light-emitting substrate holding frame 104, and multiple substrates such as a battery control substrate 70, a light-receiving substrate 80 and a light-emitting substrate 85 are provided on this basis.

[0173] exist Figure 26 , Figure 27 , Figure 28 In the movable frame 105, there are a frame fixing part 105a with a frame surface formed parallel to the YZ plane and a guided part 105b with a frame surface formed parallel to the XY plane. In the frame fixing part 105a, the ends in the -Y direction and the +Y direction are both bent toward the +X direction to form a bending part 105f, and a base plate support part 105g that constitutes a frame surface parallel to the XY plane is formed in the bending part 105f.

[0174] like Figure 12 and Figure 13 As shown, the substrate support portion 105g supports the battery control substrate 70. The battery control substrate 70 is fixed to the substrate support portion 105g by two screws Z10. The battery control substrate 70 is in surface contact with the substrate support portion 105g, thereby transferring heat from the battery control substrate 70 to the movable frame 105.

[0175] The guided section 105b has three through holes 105c and two guided holes 105d, which will be explained later.

[0176] Next, as Figure 29 As shown, the light-emitting substrate holding frame 104 has: a base portion 104f, which forms a frame surface parallel to the XY plane; and frame support portions 104a and 104b, which are formed at a position one level higher than the base portion 104f in the +Z direction, forming a frame surface parallel to the XY plane.

[0177] An opening 104e and a screw through-hole 104g are formed in the base portion 104f. The opening 104e functions to allow the focusing member 87 to pass through in the -Z direction (see reference). Figure 12 On the lower surface of the base portion 104f, three screws Z12 (see reference) are used. Figure 12 The light-emitting substrate 85 is fixed thereon. The light-emitting substrate 85 is in contact with the base portion 104f surface, thereby transferring the heat of the light-emitting substrate 85 to the light-emitting substrate holding frame 104.

[0178] Furthermore, a connecting portion 104d is formed at the end of the base portion 104f in the -X direction, which forms a frame surface parallel to the YZ plane. Similarly, a connecting portion 104c is formed at the end of the frame support portion 104a in the -X direction, which forms a frame surface parallel to the YZ plane.

[0179] Connecting parts 104c and 104d are connected by screw Z3 (see reference). Figure 26 The frame fixing part 105a is fixed to the movable frame 105. In addition, the connecting parts 104c and 104d are in surface contact with the frame fixing part 105a, thereby transferring the heat of the light-emitting part substrate holding frame 104 to the movable frame 105.

[0180] like Figure 27 As shown, frame support portions 104a and 104b support the light-receiving substrate holding frame 103. The screw indicated by reference numeral Z4 is the screw that fixes the light-receiving substrate holding frame 103 to the frame support portion 104a. Figure 27 The screw Z5 shown will be described later.

[0181] The light-receiving substrate holding frame 103 contacts the frame support portions 104a and 104b, thereby transferring heat from the light-receiving substrate holding frame 103 to the light-emitting substrate holding frame 104.

[0182] Next, as Figure 15 , Figure 16 , Figure 17 As shown, the light-receiving substrate holding frame 103 includes: a base portion 103a, which forms a frame surface parallel to the XY plane; and substrate support portions 103f and 103g, which are formed at a position one level higher than the base portion 103a in the +Z direction. The substrate support portions 103f and 103g support the light-receiving substrate 80. The substrate support portions 103f and 103g are in contact with the surface of the light-receiving substrate 80, thereby transferring heat from the light-receiving substrate 80 to the light-receiving substrate holding frame 103.

[0183] An opening 103b, a positioning hole 103c, and an elongated hole 103d that is longer in the X-axis direction are formed in the base portion 103a of the light-receiving substrate holding frame 103. In addition, a threaded hole 103k and a protrusion 103h are formed in the substrate support portion 103f, and a threaded hole 103m and a protrusion 103j are formed in the substrate support portion 103g.

[0184] like Figure 14 As shown, a positioning hole 80a and a screw insertion hole 80b are formed at the end in the +Y direction of the light-receiving substrate 80. The protrusion 103h of the light-receiving substrate holding frame 103 engages with the positioning hole 80a. The screw insertion hole 80b is for screws Z11 (see reference) to fix the light-receiving substrate 80 to the substrate support portion 103f. Figure 13 ) Insert.

[0185] In addition, such as Figure 14As shown, in the light-receiving substrate 80, a screw insertion hole 80c and an elongated hole 80d in the Y-axis direction are formed at the end. The screw insertion hole 80c is for screws Z11 (see reference) to fix the light-receiving substrate 80 to the substrate support 103g. Figure 13 The protrusion 103j of the light-receiving substrate holding frame 103 is fitted into the elongated hole 80d.

[0186] The X-axis positions of the light-receiving substrate holding frame 103 and the light-receiving substrate 80 are defined by the engagement of the protrusion 103h with the positioning hole 80a and the engagement of the protrusion 103h with the elongated hole 80d. Furthermore, since the elongated hole 80d is a longer hole in the Y-axis direction, the Y-axis positions of the light-receiving substrate holding frame 103 and the light-receiving substrate 80 are defined by the engagement of the protrusion 103h with the positioning hole 80a.

[0187] As described above, the positioning hole 80a and the protrusion 103h, as well as the elongated hole 80d and the protrusion 103j, constitute a positioning mechanism 90 that determines the relative position of the light-receiving substrate 80 and the light-receiving substrate holding frame 103 in a direction intersecting the Z-axis direction.

[0188] Next, as Figure 15 As shown, the aperture forming member 89, the intermediate member 88, and the light-concentrating member 87 are positioned on the light-receiving substrate holding frame 103. In this embodiment, the aperture forming member 89, the intermediate member 88, and the light-concentrating member 87 are all formed of black resin material.

[0189] like Figure 18 , Figure 19 As shown, these three components are positioned by the first protrusion 87d and the second protrusion 87e formed on the focusing component 87. The first protrusion 87d is inserted through the positioning hole 88b formed in the intermediate component 88, and further through the positioning hole 89b formed in the aperture forming component 89. The second protrusion 87e is inserted through the elongated hole 88c formed in the intermediate component 88, and further through the elongated hole 89c formed in the aperture forming component 89.

[0190] Here, since the elongated holes 88c and 89c are longer in the X-axis direction, the relative positions of the three components in the X-axis direction are defined by the first protrusion 87d passing through the positioning holes 88b and 89b. Furthermore, the relative positions of the three components in the Y-axis direction are defined by the first protrusion 87d and the second protrusion 87e.

[0191] Furthermore, the first protrusion 87d and the positioning hole 103c formed on the light-receiving substrate holding frame 103 (see reference) Figure 15 , Figure 17The engagement of the two components defines the positions of the three components and the light-receiving substrate holding frame 103 in the X-axis and Y-axis directions. Furthermore, the second protrusion 87e enters the elongated hole 103d formed in the light-receiving substrate holding frame 103. The elongated hole 103d is longer in the X-axis direction; therefore, the engagement of the second protrusion 87e with the elongated hole 103d defines the positions of the three components and the light-receiving substrate holding frame 103 in the Y-axis direction.

[0192] In addition, such as Figure 19 As shown, a screw through-hole 89d is formed on the aperture forming member 89, a screw through-hole 88d is formed on the intermediate member 88, and a screw through-hole 87f is formed on the focusing member 87. Screw Z5 (refer to...) Figure 27 ) Insert these screw through holes and the screw through holes 104g formed in the light-emitting part substrate holding frame 104 (refer to Figure 29 The screw Z5 engages with the threaded hole 103e of the light-receiving substrate holding frame 103, thereby fixing the three components together with the light-emitting substrate holding frame 104 to the light-receiving substrate holding frame 103.

[0193] In addition, such as Figure 18 As shown, the light-concentrating member 87 has a disk-shaped second base portion 87g formed in the first base portion 87c. This second base portion 87g and the opening 104e formed in the light-emitting portion substrate holding frame 104 (see reference) Figure 29 ) Inlay.

[0194] Next, as Figure 19 As shown, a disc-shaped protrusion 89e is formed on the aperture forming member 89, and an aperture portion 89a is formed at its center. The aperture portion 89a is circular when viewed from the Z-axis direction. Figure 10 As shown, the aperture section functions as a means of reducing the amount of light passing through the bandpass filter 7 and heading towards the optical filter 3 (incident light processing unit 2). The light-receiving substrate holding frame 103 is a frame that is disposed opposite to the light-receiving substrate 80 and has substrate support portions 103f and 103g formed at a position one level higher than the base portion 103a in the +Z direction, and is shaped to avoid the optical filter 3. It is an example of a frame that fixes the aperture section forming member 89 and the light-receiving substrate 80.

[0195] Additionally, the protrusion 89e and the opening 103b formed in the light-receiving substrate holding frame 103 (see reference) Figure 15 , Figure 17 ) Inlay.

[0196] Here, as Figure 20 , Figure 10As shown, the gap between the light-receiving substrate holding frame 103 and the optical filter 3 is filled by the plastic member 8. That is, when an external force is applied to the optical filter 3 in the Z-axis direction, it has an adverse effect on the colorimetric results. Therefore, it is necessary to form a gap between the light-receiving substrate holding frame 103 and the optical filter 3 so that the light-receiving substrate holding frame 103 does not come into contact with the optical filter 3. However, if it is subjected to an impact such as falling, the components constituting the optical filter 3 may also peel off in the Z-axis direction. Based on this viewpoint, it is possible to consider forming a gap between the light-receiving substrate holding frame 103 and the optical filter 3 and placing an elastic material or the like in the gap. However, if it is an elastic material, the external force will always act on the optical filter 3, which is not preferable.

[0197] Based on this viewpoint, in this embodiment, the gap between the light-receiving substrate holding frame 103 and the optical filter 3 is filled by the plastic member 8. As a result, external forces are difficult to apply to the optical filter 3 under normal conditions, and the optical filter 3 can be supported by the plastic member 8 when an impact is applied, thus suppressing the peeling of the components constituting the optical filter 3.

[0198] As a plastic component 8, acrylic gel can be used, for example.

[0199] Next, the movable unit 1e, constructed as described above, is configured 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. With the guided portion 105b between the first unit 1c and the second unit 1d, the tube 108 passes through the tube insertion hole 105c formed in the guided portion 105b (see reference). Figure 12 , Figure 26 Additionally, the guide shaft 107 passes through the guide holes 105d and 105e formed in the guided portion 105b (see reference). Figure 12 , Figure 26 ).

[0200] Therefore, the movable frame 105, i.e., the movable unit 1e, can be displaced relative to the fixed unit 1b along the Z-axis.

[0201] In addition, the inner diameter of the tube insertion through hole 105c is formed to have a larger margin than the outer diameter of the tube 108, so that the contact between the tube 108 and the tube insertion through hole 105c is configured such that the displacement of the movable unit 1e will not become a large resistance.

[0202] Furthermore, unlike the guided hole 105d, the guided hole 105e is formed into a slightly elongated ellipse in the Y-axis direction. Thus, the Y-axis position of the movable unit 1e relative to the fixed unit 1b is defined by the engagement of the guided hole 105d with the guide shaft 107.

[0203] In addition, the position of the movable unit 1e relative to the fixed unit 1b in the X-axis direction 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.

[0204] like Figure 9 , Figure 31 As shown, elastic members 95 are 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 positioned with its free length shortened, exerting a pressing force between the guided portion 105b and the first unit 1c, and also 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. Furthermore, in the event of a Z-axis impact on the internal unit 1a of the device, the elastic force of the elastic member 95 mitigates the impact applied to the movable unit 1e.

[0205] In addition, polyurethane foam can be used as an elastic component 95, for example.

[0206] The thickness, hardness, and area on the XY plane of the elastic member 95 in the Z-axis direction are preferably selected such that, when vibration or impact is applied to the internal unit 1a of the device, or when it is left for a long time, no gaps without the elastic member 95 are generated between the guided part 105b and the first unit 1c, and between the guided part 105b and the second unit 1d.

[0207] The connection structure between the internal units and the frame of the device

[0208] Next, the connection structure between the internal unit 1a and the frame will be explained.

[0209] like Figure 32 As shown, unit fixing portions 51m and 51n, forming a plane parallel to the XY plane, are provided on the upper inner side of the main frame 51. In the unit fixing portion 51m, a contact portion 101d (refer to) formed on the first battery holding frame 101 is fixed by screw Z9. Figure 7 The contact portion 101d forms a surface parallel to the XY plane and contacts the surface of the unit fixing portion 51m.

[0210] Similarly, on the unit fixing part 51n, a contact part 101e formed on the first battery holding frame 101 (see reference) is fixed by screw Z9. Figure 7 The contact portion 101e forms a surface parallel to the XY plane and contacts the surface of the unit fixing portion 51n.

[0211] Thus, the internal unit 1a of the device is connected to the main frame 51 in such a way that it is held on the upper part of the main frame 51.

[0212] The upper frame 52 surrounding the operation section 14 and the display section 15 on the upper part of the color measuring device 1 (see reference) Figure 3 ) by screw Z15 (refer to) engaging with threaded holes 51p formed at the four corners of the upper part of the main frame 51. Figure 11 It is fixed to the main frame 51.

[0213] Additionally, the opening forming member 21 at the bottom of the colorimetric device 1 (see reference) Figure 5 , Figure 9 As described above, the connecting portions 106f and 106e are threadedly fixed to the bottom frame 106 provided at the bottom of the internal unit 1a of the device (see reference). Figure 23 Additionally, the bottom first frame 53A surrounding the bottom of the colorimetric device 1 is also... Figure 9 The screws Z14 shown are threaded onto the bottom frame 106. The bottom second frame 53B is secured by... Figure 9 The screw Z13 shown is fixed to the bottom frame 106 together with the opening forming member 21.

[0214] Furthermore, in the assembled state of each frame, Figure 9 The part indicated by reference numeral B1 in the attached drawing, namely the connection part between the main frame 51 and the upper frame 52, is configured to overlap each other differently in the direction from the outside of the device toward the inside of the device (see also...). Figure 11 Similarly, the parts indicated by reference numeral B2, namely the connection between the main frame 51 and the bottom first frame 53A, and the connection between the main frame 51 and the bottom second frame 53B, are also configured to overlap differently in the direction from the outside of the device toward the inside of the device. This suppresses the entry of dust and light from the outside of the device into the inside.

[0215] In addition, the location of the wired IF12 in the main frame 51 is formed as an opening, which poses a risk that dust and light may enter the device from the outside. However, a cover member 27 is provided at the location of the wired IF12 to suppress dust and light from entering the device.

[0216] Characteristic structure and function of colorimetric devices

[0217] The following describes the characteristic structure and function of the colorimetric device 1 constructed as described above.

[0218] First, the main reference Figure 7The internal unit 1a of the device includes: 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 is capable of displacement 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; and at least one elastic member 95 (see reference). Figure 9 , Figure 31 The movable unit 1e is held in position relative to the fixed unit 1b in the Z-axis direction by means of elasticity. Moreover, the movable unit 1e is shock-buffered in the Z-axis direction by means of the elastic member 95. As a result, it is difficult for the opening 21a in the direction intersecting the Z-axis direction to be offset from the incident light processing unit 2, and even if an impact-buffering structure is used to buffer the impact applied to the incident light processing unit 2, appropriate colorimetric results can be obtained.

[0219] Furthermore, because an impact-absorbing structure is adopted relative to the Z-axis direction, it is possible to suppress the increase in size and cost of the device compared to a structure in which the impact-absorbing structure is set in a direction with high impact resistance. In this embodiment, the direction with high impact resistance is the direction intersecting the Z-axis direction.

[0220] In addition, the total weight of the internal unit 1a is not applied to the impact buffer structure, i.e., the elastic member 95, and only the weight of the movable unit 1e is applied to the elastic member 95. Therefore, it is possible to suppress the increase in size and cost of the elastic member 95, and thus suppress the increase in size and cost of the device.

[0221] Alternatively, it can be configured such that the gap between the guided part 105b and the movable unit 1e is eliminated, i.e., the gap is omitted. Figure 9 , Figure 31 The upper elastic member 95 shown is provided only on the lower side. As a result, the impact applied to the movable unit 1e in the Z-axis direction when the device is dropped with the bottom surface 50f facing downwards can be suppressed.

[0222] Furthermore, 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 in the Z-axis direction relative to the first unit 1c, and connected to the first unit 1c with a distance between them 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. Moreover, the movable unit 1e has a guided portion 105b located between the first unit 1c and the second unit 1d and guided by the guide shaft 107. Thus, a device capable of displacement of the movable unit 1e in the Z-axis direction can be obtained with a simple structure and low cost.

[0223] Furthermore, the elastic member 95 is positioned between the first unit 1c and the guided portion 105b, and between the second unit 1d and the guided portion 105b, with its free length in the Z-axis direction reduced. As a result, the elastic member 95 is always compressed, thus the position of the movable unit 1e in the Z-axis direction is stable, and the position of the elastic member 95 is difficult to shift in directions intersecting the Z-axis direction.

[0224] In addition, such as Figure 30 As shown, when viewed from the Z-axis direction, the center of gravity P2 of the elastic member 95 is located at the position corresponding to the center of gravity P1 of the movable unit 1e. Therefore, when the movable unit 1e displaces along the Z-axis direction against the elasticity of the elastic member 95, it is difficult to generate a force in a direction intersecting the Z-axis relative to the movable unit 1e. Thus, the movable unit 1e can displace smoothly along the Z-axis direction.

[0225] Furthermore, the position of the center of gravity P2 of the elastic member 95 corresponding to the position of the center of gravity P1 of the movable unit 1e means that it is not limited to the case where the center of gravity P2 and the center of gravity P1 are completely consistent when viewed from the Z-axis direction, but can also be slightly offset within the range that can achieve the above-mentioned effect.

[0226] In addition, such as Figure 7 As shown, the battery 17, which serves as the power supply source for the device, is installed in the fixed unit 1b. Therefore, the weight of the battery 17, which is a heavy object, will not be applied to the elastic member 95, i.e., the impact buffer structure. This also helps to suppress the increase in size and cost of the elastic member 95, and thus helps to suppress the increase in size and cost of the device.

[0227] In addition, such as Figure 9 As shown, a light-emitting substrate 85, a light-receiving substrate 80, a battery control substrate 70, and a panel substrate 65 are sequentially stacked from the opening forming member 21 toward the display unit 15 in the Z-axis direction, thus suppressing the device size in the direction intersecting the Z-axis direction.

[0228] Furthermore, the structure in which the internal unit 1a of the device is composed of a fixed unit 1b and a movable unit 1e, and the movable unit 1e is held in position relative to the fixed unit 1b by the elasticity of the elastic member 95, can also be applied to other electronic devices. Such an electronic device includes: a frame forming the outer casing of the device; and an internal unit disposed inside the frame, the internal unit comprising: a fixed unit connected to the frame; a movable unit capable of displacement in a predetermined direction relative to the fixed unit; and at least one elastic member that elastically holds the movable unit in position relative to the fixed unit in the predetermined direction.

[0229] Next, as Figure 15 , Figure 16As shown, the light-receiving substrate holding frame 103 is disposed opposite to the light-receiving substrate 80, and is a frame shaped to avoid the optical filter 3. An aperture portion forming member 89, i.e., an aperture portion 89a, is positioned on the light-receiving substrate holding frame 103.

[0230] Here, if the optical filter 3 can be directly mounted on the light-receiving substrate holding frame 103, then the opening 32a of the optical filter 3 (refer to...) Figure 2 The relative position of the optical filter 3 and the aperture section 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 substrate holding frame 103 of the light receiving section.

[0231] However, in this embodiment, the light-receiving substrate 80 and the light-receiving substrate holding frame 103 equipped with the optical filter 3 are positioned relative to each other by the positioning mechanism 90 described above, in the direction that intersects the central axis (optical axis CL) of the aperture section 89a, i.e., the direction that intersects the Z-axis direction.

[0232] With this structure, the position of the aperture portion 89a relative to the light-receiving substrate holding frame 103 is defined, and the position of the light-receiving substrate 80 equipped with the optical filter 3 is also defined. Therefore, even in a structure where the optical filter 3 is not directly mounted on the light-receiving substrate holding frame 103, it is possible to suppress the opening 32a of the aperture portion 89a and the optical filter 3 (see reference 103). Figure 2 The positional offset on the XY plane can yield appropriate colorimetric results.

[0233] In this embodiment, the aperture portion 89a is formed on the aperture portion forming member 89, and the aperture portion forming member 89 is positioned relative to the light-receiving substrate holding frame 103. However, it is also possible to configure it such that an opening is formed in the light-receiving substrate holding frame 103, and this opening functions as an aperture portion. In this case, from the viewpoint of ensuring colorimetric accuracy, it is particularly preferable that the light-receiving substrate holding frame 103 is treated with black anodized aluminum to suppress light reflection.

[0234] Furthermore, as in this embodiment, in a structure where the aperture portion 89a is formed on the aperture portion forming member 89 and the aperture portion forming member 89 is positioned relative to the light-receiving substrate holding frame 103, if the aperture portion forming member 89 is formed of black resin material and the anodic electroplating aluminum treatment of the light-receiving substrate holding frame 103 is omitted, colorimetric accuracy can be ensured and the cost increase of the device can be suppressed.

[0235] In addition, other materials may also be used for the light-receiving substrate holding frame 103 and the aperture forming member 89.

[0236] Furthermore, the colorimetric device 1, viewed from the Z-axis direction, has a long side direction (Y-axis) and a short side direction (X-axis), and the light-receiving substrate 80 is formed in a shape extending along the Y-axis. Moreover, the optical filter 3 is disposed in the light-receiving substrate 80 at the center position Yc of the light-receiving substrate 80 from the long side direction (see reference). Figure 14 The position is offset to one side, i.e., in the +Y direction. Then, the positioning mechanism 90 determines the relative position of the light-receiving substrate 80 and the light-receiving substrate holding frame 103 at a point in the +Y direction from the center position Yc (positioning hole 80a and protrusion 103h) in the Y-axis direction. As a result, the positional relationship between the light-receiving substrate holding frame 103, which is formed to extend along the Y-axis, and the light-receiving substrate 80 is determined to be close to the optical filter 3, and the positional offset between the aperture portion 89a and the optical filter 3 can be appropriately suppressed.

[0237] In this embodiment, the positioning mechanism 90 is configured to include: protrusions (protrusions 103h and 103j) disposed on one of the light-receiving substrate 80 and the light-receiving substrate holding frame 103; and fitting holes (positioning holes 80a and elongated holes 80d) disposed on the other of the light-receiving substrate 80 and the light-receiving substrate holding frame 103, for the protrusions to fit into. Specifically, in this embodiment, the positioning mechanism 90 includes a positioning hole 80a and a protrusion 103h fitting therewith, and an elongated hole 80d and a protrusion 103h fitting therewith.

[0238] Therefore, the positioning mechanism 90 can be constructed at low cost.

[0239] In addition, in this embodiment, a fitting hole is provided on the light-receiving substrate 80 and a protrusion is provided on the light-receiving substrate holding frame 103. However, it is also possible to provide a protrusion on the light-receiving substrate 80 and a fitting hole on the light-receiving substrate holding frame 103, in the opposite way.

[0240] Furthermore, in this embodiment, a cylindrical member, namely a light-concentrating member 87, which forms a path for light from the measurement object 200 toward the aperture portion 89a, is disposed on the light-receiving substrate holding frame 103. In other words, the light-concentrating member 87 is positioned on the light-receiving substrate holding frame 103. Thus, the relative position of the light-concentrating member 87 and the aperture portion 89a in the XY plane is appropriately determined.

[0241] Furthermore, in this embodiment, the light-receiving substrate holding frame 103 is made of aluminum, and its surface is subjected to black anodized aluminum plating. This suppresses the reduction in colorimetric accuracy caused by light reflection from the light-receiving substrate holding frame 103.

[0242] Next, in Figure 3In the colorimetric device 1, there are: an internal unit 1a having an incident light processing unit 2; and a main frame 51 covering the internal unit 1a to form 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 made of aluminum. The main frame 51 is made of aluminum and is anodized aluminum.

[0243] Thus, the frame assembly 100 and the main frame 51 are made of aluminum, resulting in good heat dissipation. Furthermore, since the main frame 51 is anodized aluminum, its radiative heat dissipation is further enhanced. With this structure, the heat generated inside the device can be effectively released to the outside, thereby obtaining appropriate colorimetric results.

[0244] In addition, in this embodiment, the anodized aluminum treatment of the main frame 51 is black anodized aluminum treatment, but it is not limited to this.

[0245] In this embodiment, the upper frame 52, the bottom first frame 53A, and the bottom second frame 53B are formed of resin material, but they can also be formed of aluminum. Alternatively, black anodized aluminum plating or anodized aluminum plating of other colors can also be performed.

[0246] Additionally, the frame assembly 100 has contact portions 101d and 101e (see reference) that contact the main frame 51 on its inner side. Figure 7 This allows for efficient heat transfer from the frame component 100 to the main frame 51.

[0247] Furthermore, in this embodiment, since the multiple frames constituting the frame assembly 100 are also treated with black anodized aluminum like the main frame 51, the 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. Alternatively, in this case, anodized aluminum of other colors can be used instead of black anodized aluminum.

[0248] Alternatively, the anodized aluminum plating process for the multiple frames constituting the frame assembly 100 can be omitted.

[0249] Furthermore, the main frame 51 has a long side direction (Y-axis direction) and a short side direction (X-axis direction) when viewed from above, and has a holding recess 51g on the side wall in the short side direction (see reference). Figure 31 As a result, the operability of the device is improved, and the surface area of ​​the side wall of the main frame 51 is increased, thus improving heat dissipation.

[0250] In addition, such as Figure 7As shown, the frame assembly 100 includes a battery holding portion 100a that is shaped to surround the battery 17. This allows heat generated from the battery 17 to be effectively transferred to the battery holding portion 100a and efficiently released to the outside of the device.

[0251] In addition, the frame assembly 100 includes a movable frame 105 that serves as a substrate holding part for holding the light-receiving substrate 80 on which the incident light processing part 2 is provided, and the battery holding part 100a and the movable frame 105 are arranged at a distance from each other in the Z-axis direction.

[0252] That is, both the battery 17 and the light-receiving substrate 80 are heat sources. If they are placed in close proximity, efficient heat dissipation may not be possible. However, as described above, the battery holding part 100a and the movable frame 105 are arranged at intervals in the Z-axis direction, thus enabling efficient heat dissipation.

[0253] Furthermore, in this 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. As a result, the movable frame 105 transfers the heat of the movable unit 1e to the main frame 51, and then effectively releases it outside the device via the main frame 51.

[0254] Next, as referred to Figure 31 As explained, a first corner C1 where the first wall W1 intersects with the third wall W3, a second corner C2 where the first wall W1 intersects with the fourth wall W4, a third corner C3 where the second wall W2 intersects with the fourth wall W4, and a fourth corner C4 where the second wall W2 intersects with the third wall W3 are formed on the inner side of the battery holding part 100a.

[0255] When battery 17 is cut along the XZ plane, its upper part is formed into an arc shape, and its lower part, facing the first wall W1, is formed to narrow its width by widening the gap between it and the third wall W3 and the fourth wall W4. This results in the following state: a gap S1 is formed between the first corner C1 and battery 17; a gap S2 is formed between the second corner C2 and battery 17; a gap S3 is formed between the first corner C3 and battery 17; and a gap S4 is formed between the fourth corner C4 and battery 17.

[0256] Furthermore, in this embodiment, a screw Z1 is provided in the gap S2 to assemble the first battery holding frame 101 and the second battery holding frame 102 constituting the battery holding part 100a.

[0257] In addition, screws Z9 are provided in the gaps S3 and S4 to assemble the main frame 51 and the horizontal part 101b of the first battery holding frame 101.

[0258] As described above, since the screw associated with the battery holding portion 100a is disposed by utilizing the gap formed inside the battery holding portion 100a, it is possible to suppress the enlargement of the device caused by the constituent elements of the battery holding portion 100a.

[0259] In addition, the components of the battery holding part 100a are configured using gaps S2, S3, and S4 in this embodiment, but it is sufficient to use at least one of gaps S1, S2, S3, and S4.

[0260] Furthermore, the battery 17 is shaped as described above, with its lower portion facing the first wall portion W1 and its width decreasing by widening the distance between it and the third wall portion W3 and the fourth wall portion W4, thus widening the gaps S1 and S2. Moreover, since the screw Z1 is arranged using the gap S2 formed in this way, the large size of the device caused by the components of the battery holding part 100a can be further suppressed.

[0261] In addition, the components of the battery holder 100a are not limited to screws, but may also be other components, such as a connector for connecting the battery 17. Figure 33 Other embodiments of the colorimetric device 150 are shown, with the same reference numerals used for structures identical to those already described. Figure 33 In the color measuring device 150 shown, a screw Z1 is disposed inside the battery holding part 151 using a gap S3, and a screw Z9 is disposed using a gap S4.

[0262] Furthermore, in this embodiment, the battery control board 70 is positioned close to the battery holding portion 151, thereby allowing the first connector 17c, which is connected to the first battery connector 72, to enter the gap S1, i.e., to be configured using the gap S1. Similarly, the second connector 17d, which is connected to the second battery connector 73, also enters the gap S2, i.e., to be configured using the gap S2. With this structure, the enlargement of the device can be suppressed.

[0263] In addition, Figure 33 In the structure shown, the first battery connector 72 and the second battery connector 73 do not enter the gaps S1 and S2 respectively, but they can also be configured to enter the gaps S1 and S2.

[0264] In addition, the structure configured using at least one of the gaps S1, S2, S3, and S4 can be any one of the following: a connector for connecting the battery 17, screws for assembling the plurality of frames constituting the battery holding part 100a, and screws for assembling the main frame 51 and the battery holding part 100a, or any two, or all of them.

[0265] Alternatively, the structure relative to a gap configuration can be any one of the following: a connector connecting the battery 17, screws assembling multiple frames constituting the battery holding part 100a, and screws assembling the main frame 51 and the battery holding part 100a; or any two; or all of them.

[0266] This invention is not limited to the embodiments described above. Various modifications can be made within the scope of the invention as described in the claims, and these modifications are of course also included within the scope of this invention.

[0267] For example, in the above embodiment, the color measuring device 1 has a built-in battery 17, but it can also be configured such that the battery 17 is removable, that is, it can also be configured such that the color measuring device 1 does not have a built-in battery 17. In addition, in this case, the battery 17 can also be a primary battery that does not undergo repeated charging and discharging.

[0268] Furthermore, in this 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 allows a predetermined wavelength component of the incident light to pass through, but is not limited to this. For example, as a spectroscopic method, a spectroscopic method utilizing a diffraction grating can also be used. In addition, as a colorimetric principle, a device structure employing a direct reading method of stimulus values ​​based on the three stimulus values ​​that form the basis of color can also be used.

[0269] In addition, LEDs are used as the light-emitting element for the light-emitting part 9 in this embodiment, but it is not limited to this; for example, a xenon lamp may also be used.
