Embodiments for Carrying Out the Invention

[0007] Hereinafter, the present invention will be schematically described. The color measurement device according to the first aspect is formed in an opening forming member disposed on the bottom surface of the device, and includes an opening for taking light reaching from a measurement object into the device, an incident light processing unit that processes the light incident through the opening, a battery that supplies power to the incident light processing unit, and a first circuit board equipped with a wireless communication unit. Characteristically, when viewed from a first direction which is a direction intersecting the bottom surface and the upper surface which is the surface opposite to the bottom surface, there is a portion where the first circuit board and the battery overlap.

[0008] According to this aspect, when viewed from the first direction, which is the direction intersecting the bottom surface and the upper surface opposite to the bottom surface, there is a portion where the first circuit board equipped with the wireless communication unit and the battery overlap. Therefore, compared with the configuration in which the first circuit board and the battery are arranged in a direction intersecting the first direction, the device dimensions in the direction intersecting the first direction can be suppressed.

[0009] A second aspect is characterized in that, in the first aspect, when viewed from the first direction, the wireless communication unit is accommodated within the region of the battery. According to this aspect, when viewed from the first direction, in the configuration where the wireless communication unit is accommodated within the region of the battery, the operational effects of the first aspect described above can be obtained.

[0010] A third aspect is characterized in that, in the first or second aspect, when viewed from the first direction, the battery is accommodated within the region of the first circuit board. According to this aspect, since the battery is accommodated within the region of the first circuit board when viewed from the first direction, the device dimensions in the direction intersecting the first direction can be further suppressed.

[0011] A fourth aspect is characterized in that, in any of the first to third aspects, it includes a housing forming the outer shell of the device, a main body assembly provided inside the housing, and a frame assembly made of a metal material constituting the base of the main body assembly. The frame assembly includes a battery holding portion having a shape surrounding the battery, a notch portion is formed in the battery holding portion, and the wireless communication unit is disposed at a position inside the battery holding portion and facing the notch portion.

[0012] According to this aspect, since the frame assembly includes a battery holding portion having a shape surrounding the battery, the heat generated from the battery is transmitted to the battery holding portion and dissipated. And since the wireless communication unit is provided using the inside of the battery holding portion, miniaturization of the device can be achieved. Here, when the wireless communication unit is provided inside the battery holding unit, heat dissipation from the battery holding unit may have an adverse effect on the wireless communication unit. However, a notch is formed in the battery holding unit, and the wireless communication unit is disposed at a position facing the notch, so that heat dissipation from the battery holding unit can be suppressed from having an adverse effect on the wireless communication unit.

[0013] A fifth aspect is, in any one of the first to fourth aspects, including a second circuit board including the incident light processing unit, a third circuit board to which the battery is connected, and a fourth circuit board including a light emitting unit that emits light for measurement, and in the first direction, in order from the bottom surface toward the top surface, the fourth circuit board, the second circuit board, the third circuit board, the battery, and the first circuit board are arranged to overlap.

[0014] According to this aspect, since the fourth circuit board, the second circuit board, the third circuit board, the battery, and the first circuit board are arranged to overlap in order from the bottom surface toward the top surface in the first direction, the device dimensions in a direction intersecting the first direction can be suppressed.

[0015] A sixth aspect is, in any one of the first to third aspects, characterized by having a portion where the incident light processing unit and the battery overlap when viewed from the first direction. According to this aspect, since there is a portion where the incident light processing unit and the battery overlap when viewed from the first direction, the device dimensions in a direction intersecting the first direction can be suppressed compared to a configuration in which the incident light processing unit and the battery are arranged side by side in a direction intersecting the first direction.

[0016] A seventh aspect is, in any one of the first to sixth aspects, characterized in that the incident light processing unit includes a wavelength variable optical filter that transmits a predetermined wavelength component of the incident light, and a light receiving unit that receives the light transmitted through the optical filter. According to this aspect, in a configuration in which the incident light processing unit includes a wavelength-variable optical filter that transmits a predetermined wavelength component of the incident light, and a light receiving unit that receives the light transmitted through the optical filter, any of the operational effects of the first to sixth aspects described above can be obtained.

[0017] An eighth aspect is characterized in that, in the seventh aspect, the optical filter is a Fabry - Perot etalon. According to this aspect, in a configuration in which the optical filter is a Fabry - Perot etalon, the operational effect of the seventh aspect described above can be obtained.

[0018] The color measuring device according to the ninth aspect is formed in an opening - forming member disposed on the bottom surface of the device, and includes an opening for taking in light reaching from the measurement target into the device, an incident light processing unit that processes the light incident through the opening, a battery holding unit that holds a battery for supplying power to the incident light processing unit, and a first circuit board mounted with a wireless communication unit. When viewed from a first direction, which is a direction intersecting the bottom surface and the upper surface opposite to the bottom surface, there is a portion where the first circuit board and the battery holding unit overlap.

[0019] According to this aspect, when viewed from the first direction, which is a direction intersecting the bottom surface and the upper surface opposite to the bottom surface, since there is a portion where the first circuit board mounted with the wireless communication unit and the battery holding unit overlap, compared with a configuration in which the first circuit board and the battery holding unit are arranged in a direction intersecting the first direction, the device dimensions in the direction intersecting the first direction can be suppressed.

[0020] Hereinafter, the present invention will be specifically described. Note that the X - Y - Z coordinate system shown in each figure is a rectangular coordinate system, the X - Y plane is a horizontal plane, and the Y - Z plane is a vertical plane. The Z-axis direction is the vertical direction, which is an example of the first direction intersecting the upper surface 50e and the bottom surface 50f of the color measuring device 1. The Y-axis direction is the direction orthogonal to the first direction, i.e., the vertical direction, and is an example of the second direction that is the longitudinal direction when the color measuring device 1 is viewed from the vertical direction. The X-axis direction is the direction orthogonal to the Y-axis direction and is an example of the third direction that is the lateral direction when the color measuring device 1 is viewed from the vertical direction. In this specification, the configuration of the color measuring device 1 will be described assuming that the bottom surface 50f is placed on a mounting surface parallel to the horizontal plane and that the longitudinal direction of the color measuring device 1 is along the Y-axis direction.

[0021] [Overall Configuration of Color Measuring Device 1] First, with reference to FIGS. 1 and 2, the overall configuration of the color measuring device 1 according to this embodiment will be described. The color measuring device 1 is provided with a configuration for color measurement based on the light reaching from the measurement target 200. Examples of the light reaching from the measurement target 200 include the light reflected by the measurement target 200 and the light emitted by the measurement target 200 itself. The color measuring device 1 includes a band-pass filter 7, an optical filter device 3, a light receiving unit 4, a 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. The band-pass filter 7, the optical filter device 3, and the light receiving unit 4 constitute an incident light processing unit 2 that processes the light incident from the measurement target 200.

[0022] The band-pass filter 7 transmits light in the visible light range, for example, light in the range of 380 nm to 720 nm, and cuts off light in the ultraviolet and infrared light ranges among the light incident from the measurement target 200. As a result, light in the visible light range enters the optical filter device 3. The light reaching the band-pass filter 7 from the measurement target 200 reaches the band-pass filter 7 through the opening 21a and the measurement window 87a (see FIG. 20) described later.

[0023] The optical filter device 3 selectively transmits any wavelength component from the visible light that has passed through the band-pass filter 7. The light transmitted through the optical filter device 3 is incident on a photodiode 4a (see FIG. 20), which is an example of a light receiving element, and is processed by a light receiving unit 4 including the photodiode 4a. The light receiving unit 4 converts the intensity of the received light into a voltage value, and further converts the voltage value into a digital signal and outputs it to the MCU 10. The color measuring device 1 can measure the spectrum of the measurement target 200 by repeatedly performing wavelength selection by the optical filter device 3 and acquisition of the received light intensity using the light receiving unit 4.

[0024] Here, with reference to FIG. 2, the configuration of the optical filter device 3 will be described. In the present embodiment, the optical filter device 3 is a wavelength-variable Fabry-Perot etalon that transmits a predetermined wavelength component among the light incident from the measurement target 200, and is a wavelength filter that utilizes multiple interference of two opposing reflecting surfaces. In FIG. 2, the optical filter device 3 includes a wavelength-variable interference filter 45, and the wavelength-variable interference filter 45 is built into the interior of an exterior formed by a first glass member 30, a second glass member 31, and a case 32.

[0025] The case 32 and the first glass member 30, and the case 32 and the second glass member 31 are joined by a joining member 33 such as a low melting point glass or an epoxy resin. Also, the wavelength-variable interference filter 45 and the case 32 are fixed by a fixing material 34 such as an adhesive. Conductivity is established between the electrode 36 on the outer surface of the case 32 and the wavelength-variable interference filter 45 by wire bonding 35 and wiring inside the case 32.

[0026] 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 joined by a joining film 43. Mirrors 39 are formed on the base substrate 37 and the diaphragm substrate 38, respectively. The facing mirrors 39 have their outermost surfaces formed of a conductor. The capacitance between the facing mirrors 39 is detected by a capacitance detection unit 6 (see FIG. 1). The capacitance detection unit 6 is composed of a CV (Capacitance to Voltage) converter, which converts the detected capacitance into a voltage value and further into a digital value, and then transmits it to the MCU 10. The distance between the facing mirrors 39 is controlled by an electrostatic actuator formed by the facing of a fixed electrode 40 and a movable electrode 41 that are formed concentrically when viewed from the Z-axis direction.

[0027] When a voltage is applied between the facing fixed electrode 40 and movable electrode 41, a force is generated by the electrostatic force that pulls the fixed electrode 40 and the movable electrode 41 together. At this time, the diaphragm portion 42 formed concentrically deforms, causing the mirror 39 on the diaphragm substrate 38 to be attracted toward the base substrate 37 side, and the distance between the facing mirrors 39 is controlled. Then, the wavelength of the light transmitted through the wavelength-variable interference filter 45 is selected corresponding to the distance between the facing mirrors 39.

[0028] During spectroscopic measurement, light from the measurement target 200 enters the optical filter device 3 from the side of the second glass member 31 toward the side of the first glass member 30 along the optical axis CL. The optical axis CL is parallel to the Z-axis direction and is a line passing through the centers of the opening 21a (see FIG. 20), the measurement window portion 87a (see FIG. 20), the wavelength-variable interference filter 45, and the photodiode 4a (see FIG. 20). In particular, the opening 21a, the measurement window portion 87a, and the wavelength-variable interference filter 45 (see FIG. 2) are circular when viewed from the Z-axis direction, and the optical axis CL passes through their centers. The optical axis CL may also be referred to as the center position CL hereinafter. Then, the light incident on the optical filter device 3 interferes between the opposing mirrors 39, and the light of the wavelength selected corresponding to the distance between the opposing mirrors 39 passes through the wavelength-variable interference filter 45. The light that has passed through the wavelength-variable interference filter 45 passes through the first glass member 30 and heads toward the light receiving unit 4. The above is the configuration of the optical filter device 3.

[0029] Returning to FIG. 1, the MCU 10 is a control device based on a microprocessor and incorporates a memory in which various programs and various data necessary for controlling the color measurement device 1 are stored. The MCU 10 sends control information necessary for driving the electrostatic actuator configured by the facing fixed electrode 40 and movable electrode 41, which was described with reference to FIG. 2, to an amplifier (not shown), and supplies a predetermined driving voltage from this amplifier to the optical filter device 3. Then, the MPU 10 compares the information related to the voltage value output from the capacitance detection unit 6 with the stored value, and performs feedback control of the optical filter device 3 based on this.

[0030] The light emitting unit 9 emits measurement light toward the measurement target 200. The light emitting unit 9 is composed of a plurality of light emitting elements having different wavelength distributions of emitted light, specifically, a plurality of LEDs. The MCU 10 controls the lighting and extinguishing of the light emitting unit 9.

[0031] The wired IF 12 and the wireless communication unit 13 are components for communicating with external devices. As an example, the standard for communicating via the wired IF 12 can adopt USB (Universal Serial Bus). Also, as an example, the standard of the wireless communication unit 13 can adopt Bluetooth. USB and Bluetooth are registered trademarks. The MCU 10 sends various data to an external device via the wired IF 12 or the wireless communication unit 13, and also receives various data from the external device. Also, the color measurement device 1 can charge the battery 17 by receiving power supply from an external device via the wired IF 12.

[0032] The operation unit 14 is composed of a power button and various operation setting buttons, and sends a signal corresponding to the operation to the MCU 10. The operation unit 14 will be further described later. The display unit 15 is composed of a liquid crystal panel as an example, and displays a user interface for setting color measurement conditions and various information such as color measurement results based on the signal sent from the MCU 10. The magnetic sensor 128 that sends a detection signal to the MCU 10 is a sensor for detecting the position of the shutter unit 110 described later, but the magnetic sensor 128 will be described again later.

[0033] The battery 17 is a lithium-ion secondary battery in this embodiment, and supplies power to each component part that requires power in the color measurement device 1. The component parts that receive power supply from the battery 17 include the incident light processing unit 2 described later. The battery control unit 16 performs various controls such as charge control of the battery 17.

[0034] [External Configuration of Color Measurement Device 1] Next, the external configuration of the color measurement device 1 will be described with reference to FIGS. 3, 4, 5, and 6. The device body 50 of the color measurement device 1 is configured such that its outer shell is box-shaped as a whole by the main housing 51, the upper housing 52, and the bottom housing 53. The main housing 51, the upper housing 52, and the bottom housing 53 are formed of a resin material in this embodiment. In each figure, the reference numeral 50a indicates the side surface of the device body 50 in the +Y direction, which will be referred to as the front surface 50a hereinafter.

The reference numeral 50d indicates the side surface of the device body 50 in the -Y direction, which will be referred to as the rear surface 50d hereinafter. In addition, in this specification, the terms "up", "down", "left", and "right" are used based on the direction seen from the user when the user holds and uses the color measurement device 1 as shown in FIG. 27.

[0035] In FIGS. 3 to 6, the front surface 50a is formed by the front wall portion 51a of the main housing 51, the right side surface 50b is formed by the right wall portion 51b of the main housing 51, the left side surface 50c is formed by the left wall portion 51c of the main housing 51, and the rear surface 50d is formed by the rear wall portion 51d of the main housing 51.

Reference numeral 50f indicates the -Z-direction surface of the apparatus main body 50, which will be referred to as the bottom surface 50f hereinafter.

[0036] On the upper surface 50e of the apparatus main body 50, the operation unit 14 and the display unit 15 are arranged along the Y-axis direction. The operation unit 14 includes a power button 55, a determination button 54, a return button 56, and a cross button 60. The cross button 60 is composed of an up button 61, a down button 62, a left button 63, and a right button 64. In the color measurement device 1 according to the present embodiment, all operation buttons are arranged on the upper surface 50e and are integrated in the operation unit 14.

[0037] The power button 55 is a button for turning on and off the power of the color measurement device 1. The determination button 54 is a button for determining various settings displayed on the display unit 15, that is, a button for determining color measurement conditions, and is also a button for executing color measurement. The determination button 54 has a perfect circular shape when viewed from the Z-axis direction. The return button 56 is a button for returning to the previous state in the user interface displayed on the display unit 15, and is also a button for canceling the execution of an operation.

[0038] The cross button 60 is a button for selecting various items in the user interface displayed on the display unit 15. A vertical line 58a parallel to the Y-axis direction is provided on the surface of the up button 61, and a vertical line 58b parallel to the Y-axis direction is provided on the surface of the down button 62. The vertical lines 58a and 58b are located at positions passing through the center position CL when extended in the Y-axis direction. In addition, a horizontal line 58c parallel to the X-axis direction is provided on the surface of the left button 63, and a horizontal line 58d parallel to the X-axis direction is provided on the surface of the right button 64. When extended in the X-axis direction, the horizontal lines 58c and 58d are located at positions passing through the center position CL.

[0039] Various information such as color measurement results is displayed on the display unit 15. In this embodiment, the display unit 15 is constituted by a liquid crystal display (LCD) 67 (see also FIG. 8). Hereinafter, the liquid crystal display 67 is abbreviated as LCD67. A display unit cover 57, which is a transparent member, is provided above the LCD67, and a part of the upper surface 50e is formed by this display unit cover 57. In this embodiment, as shown in FIG. 20, the structure is such that almost no step is generated between the upper surface of the display unit cover 57 and the upper surface of the operation unit 14. As a result, the upper surface 50e is configured as a flat surface with almost no step overall. However, the upper surface of the determination button 54 is slightly recessed as shown in FIG. 20, and is formed in a shape that conforms to the fingertip of the user pressing the determination button 54 as shown in FIG. 27.

[0040] As shown in FIGS. 4 and 6, a shutter unit 110 is provided on the bottom surface 50f. FIG. 4 shows a state where the shutter unit 110 is in the closed position, and FIG. 6 shows a state where the shutter unit 110 is in the open position. The shutter unit 110 can be displaced between the closed position and the open position by sliding along the Y-axis direction. Also, the shutter unit 110 is provided so that it can hold the closed position and the open position. The shutter unit 110 includes a shutter holding member 111 and a link member 113, which will be described in detail later. The shutter holding member 111 has a plurality of ribs 111a on its surface. The user can slide the shutter unit 110 in the Y-axis direction by hanging the fingertip on the ribs 111a.

[0041] By opening the shutter unit 110, the opening 21a and the measurement window portion 87a are exposed as shown in FIG. 6. The opening 21a and the measurement window portion 87a open on the bottom surface 50f of the apparatus. Here, the opening means taking in light, and for example, a transparent glass plate may be provided. As also shown in FIG. 20, the opening 21a is formed in the opening forming member 21, and the measurement window portion 87a is formed in the condensing member 87 positioned in the +Z direction with respect to the opening forming member 21. The measurement light emitted from the light emitting unit 9 passes between the condensing member 87 and the opening forming member 21 as indicated by the arrow shown inside the opening 21a in FIG. 20, and is emitted from the opening 21a toward the measurement object 200. Then, the light reaching from the measurement object 200 is taken into the apparatus through the opening 21a, and further enters the incident light processing unit 2 through the measurement window portion 87a.

[0042] As shown in FIGS. 5 and 6, the center position CL coincides with the center positions of the opening 21a and the measurement window portion 87a. The straight line VCL is a straight line parallel to the Y-axis direction and passing through the center position CL as viewed from the Z-axis direction. The straight line HCL is a straight line parallel to the X-axis direction and the Y-axis direction and passing through the center position CL as viewed from the Z-axis direction. In the present embodiment, the center position CL coincides with the center position of the determination button 54 in the X-Y plane and also coincides with the center position of the cross button 60. The power button 55 and the return button 56 are arranged symmetrically with respect to the straight line VCL as shown in FIG. 5.

[0043] Next, as shown in FIG. 3, a wired IF 12 is provided on the front surface 50a of the apparatus main body 50.

Also, two openings 50n are formed at positions in the -Z direction with respect to the opening 50m, and a user can easily carry the color measuring device 1 by passing a strap (not shown) through these two openings 50n.

[0044] As shown in FIGS. 3, 4, 21, and 22, gripping portions 50g are formed on the right side surface 50b and the left side surface 50c of the apparatus main body 50. The gripping portions 50g are constituted by recesses 51g formed in the right wall portion 51b and the left wall portion 51c of the main housing 51, respectively. The recesses 51g are formed by curved surfaces that face the center in the X-axis direction of the apparatus main body 50 as they extend in the -Z direction. By providing the gripping portions 50g, the user can easily and surely grip the apparatus main body 50.

[0045] [Substrate Configuration of Color Measuring Device 1] Next, the substrate configuration of the color measuring device 1 will be described.

Also, as shown in the figure below FIG. 10, a wireless communication unit 13, which is a communication module, is provided on the lower surface of the panel substrate 65.

[0049] Subsequently, the battery control board 70 will be described with reference to FIG. 11. The battery control board 70 realizes the functions of the battery control unit 16 (see FIG. 1). The battery control board 70 includes a reset switch 71, a wired IF 12, a first battery connector 72, and a second battery connector 73 on its upper surface as shown in the upper figure of FIG. 11. A battery control circuit (not shown in FIG. 11) is provided on the upper surface of the battery control board 70. The first battery connector 72 is connected to the battery 17 by a first battery cable 92 as shown in FIG. 8, and the second battery connector 73 is connected to the battery 17 by a second battery cable 93 as shown in FIG. 8.

[0050] The battery control board 70 is provided with a second board connection connector 74 as shown in the lower diagram of FIG. 11. When the second board connection connector 74 is fitted with the third board connection connector 82 shown in the upper diagram of FIG. 12, the battery control board 70 and the light receiving unit board 80 are connected. Thereby, the power of the battery 17 is supplied to each circuit board via the light receiving unit board 80.

[0051] Subsequently, the light receiving unit board 80 will be described with reference to FIG. 12. The light receiving unit board 80 is provided with a PD (Photo Diode) board 5 on its upper surface and also includes the above-described third board connection connector 82. The PD board 5 is provided with a photodiode 4a on its lower surface as shown in FIG. 20. The PD board 5 is a circuit board that constitutes the light receiving unit 4 (see FIG. 1). That is, the PD board 5 constitutes the incident light processing unit 2 (see FIG. 1) that processes the incident light. The light receiving unit board 80 is provided with an optical filter device 3, a fourth board connection connector 83, and a fifth board connection connector 84 on its lower surface. When the fifth board connection connector 84 is connected to the sixth board connection connector 88 shown in the lower diagram of FIG. 13 by a connection cable 91 as shown in FIG. 9, the light receiving unit board 80 and a light emitting unit board 85 described later are connected.

[0052] Note that electronic components (not shown in FIG. 11) are provided on the light receiving unit board 80. The electronic components not shown in FIG. 11 include the MCU 10 (see FIG. 1), a CV converter that constitutes the capacitance detection unit 6 (see FIG. 1), a DC / DC converter that converts the voltage of the battery 17, an amplifier that adjusts the output from this DC / DC converter under the control of the MCU 10 and supplies it to the optical filter device 3, a temperature sensor for detecting the temperature around the optical filter device 3, and the like.

[0053] Note that a shielding sheet 29 is provided so as to surround the PD board 5 and the optical filter device 3 provided on the light receiving unit board 80 as shown in FIG. 11 (see also FIG. 7). Thereby, the intrusion of external light into the PD board 5 and the optical filter device 3 is suppressed.

[0054] Next, the light-emitting unit substrate 85 will be described with reference to FIG. 13. The light-emitting unit substrate 85 includes a light condensing member 87 extending between the upper surface and the lower surface. The measurement window portion 87a described above is formed in the light condensing member 87. On the lower surface of the light-emitting unit substrate 85, a sixth substrate connection connector 88 is provided as shown in the lower figure of FIG. 13, and a plurality of light-emitting elements 86 are provided around the light condensing member 87. The plurality of light-emitting elements 86 are composed of light-emitting elements having different wavelength distributions of emitted light. Note that a light shielding member 89 is provided around the light-emitting element 86, and the light shielding member 89 suppresses leakage of measurement light emitted from the light-emitting element 86.

[0055] [Configuration of Frame Assembly] Next, the frame assembly 100 that constitutes the base of the apparatus main body 50 will be described. In FIGS. 14 to 17, the frame assembly 100 includes a main frame 101, a battery holding frame 102, a light-receiving unit substrate holding frame 103, and a bottom frame 105. In the present embodiment, all the frames are formed by bending a metal material, and more specifically, aluminum is used as the material. Note that each frame can also be formed by die casting or the like instead of bending a metal material.

[0056] Hereinafter, each frame will be sequentially described. The main frame 101 is a frame that forms the base of the apparatus main body 50, and has a main plate portion 101a that forms a frame surface extending in the Y-axis direction and the Z-axis direction, in other words, a frame surface wide in the Y-Z plane as shown in FIG. 18. The main frame 101 also has a panel substrate support portion 101b that extends from the +Z direction end portion of the main plate portion 101a in the -X direction and forms a frame surface parallel to the X-Y plane. The panel substrate support portion 101b supports the panel substrate 65 from below as shown in FIGS. 7 and 20. The panel substrate 65 is fixed to the panel substrate support portion 101b by screws (not shown). The panel substrate 65 is in surface contact with the panel substrate support portion 101b, whereby the heat of the panel substrate 65 is transmitted to the panel substrate support portion 101b, that is, the main frame 101.

[0057] As shown in FIG. 18, at the -Z direction end of the main plate portion 101a, the +Y direction end is bent in the -X direction, and further the +Z direction end is bent in the -Y direction to form a battery control board support portion 101e parallel to the X-Y plane. Similarly, at the -Z direction end of the main plate portion 101a, the -Y direction end is bent in the -X direction, and further the +Z direction end is bent in the +Y direction to form a battery control board support portion 101e parallel to the X-Y plane.

[0058] The battery control board support portion 101e supports the battery control board 70 from below as shown in FIGS. 7 and 20. Note that the battery control board 70 is fixed to the battery control board support portion 101e by screws (not shown). The battery control board 70 is in surface contact with the battery control board support portion 101e, whereby the heat of the battery control board 70 is transmitted to the battery control board support portion 101e, that is, the main frame 101.

[0059] In FIGS. 14 to 18, a frame holding portion 101f is formed below the battery control board support portion 101e so as to be parallel to the X-Y plane. The frame holding portion 101f holds the light emitting portion substrate holding frame 104 as shown in FIGS. 14 and 16. The light emitting portion substrate holding frame 104 is fixed to the lower side of the frame holding portion 101f by screws (not shown). The light emitting portion substrate holding frame 104 is in surface contact with the frame holding portion 101f. That is, the light emitting portion substrate holding frame 104 is in direct contact with the main frame 101. Thereby, the heat of the light emitting portion substrate holding frame 104 is transmitted to the frame holding portion 101f, that is, the main frame 101.

[0060] The light-emitting unit substrate holding frame 104 holds the light-emitting unit substrate 85 as shown in FIGS. 7 and 20. The light-emitting unit substrate holding frame 104 is an example of a second sub-frame that holds the light-emitting unit substrate 85. The light-emitting unit substrate 85 is fixed to the lower side of the light-emitting unit substrate holding frame 104 by screws (not shown). The light-emitting unit substrate 85 is in surface contact with the light-emitting unit substrate holding frame 104, whereby the heat of the light-emitting unit substrate 85 is transmitted to the light-emitting unit substrate holding frame 104 and then to the main frame 101.

[0061] On the lower surface of the light-emitting unit substrate holding frame 104, a bottom frame 105 is fixed by screws (not shown) as shown in FIG. 15. The bottom frame 105 is a frame for fixing one end of a torsion spring 117 (see FIG. 32) that presses a shutter unit 110 (see FIG. 32), which will be described in detail later. The bottom frame 105 has a first plate portion 105a and a second plate portion 105b, and the second plate portion 105b is in surface contact with the light-emitting unit substrate holding frame 104. Thereby, the heat of the light-emitting unit substrate holding frame 104 is transmitted to the bottom frame 105. That is, the bottom frame 105 functions as a heat sink that promotes heat dissipation of the light-emitting unit substrate holding frame 104.

[0062] In FIGS. 14 to 18, the main frame 101 has a sub-plate portion 101c that extends in the -Z direction from the -X direction end of the panel substrate support portion 101b and forms a frame surface parallel to the Y-Z plane. Here, a battery holding frame 102 is attached to the main frame 101. The sub-plate portion 101c and the panel substrate support portion 101b constitute a battery holding portion 100a that holds the battery 17 together with the battery holding frame 102 in a state where the battery holding frame 102 is attached.

[0063] The battery holding part 100a will be further described below. The battery holding frame 102 has a battery support part 102a forming a frame surface parallel to the X-Y plane. The battery support part 102a supports the battery 17 from below as shown in Fig. 20. The bottom surface of the battery 17 is in surface contact with the battery support part 102a, and thereby the heat of the battery 17 is transmitted to the battery support part 102a, that is, the battery holding part 100a.

[0064] In Figs. 14 to 17, from the -X direction end of the battery support part 102a, a first frame part 102b forming a frame surface parallel to the Y-Z plane rises in the +Z direction. Also, from the +X direction end of the battery support part 102a, a second frame part 102c forming a frame surface parallel to the Y-Z plane rises in the +Z direction. The first frame part 102b is located in the -X direction with respect to the sub-plate part 101c of the main frame 101 and is in surface contact with the sub-plate part 101c. Also, the second frame part 102c is located in the -X direction with respect to the main plate part 101a of the main frame 101 and is in surface contact with the main plate part 101a.

[0065] In this way, the battery holding part 100a is configured to surround the battery 17 by the battery holding frame 102, the panel substrate support part 101b, and the sub-plate part 101c. Note that the battery support part 102a is an example of a first wall part that supports the battery 17 from below and constitutes the battery holding part 100a. Also, the panel substrate support part 101b is an example of a second wall part facing the battery support part 102a and constitutes the battery holding part 100a. Also, the sub-plate part 101c is an example of a third wall part located in the -X direction with respect to the battery 17 and constitutes the battery holding part 100a. Also, the second frame part 102c is an example of a fourth wall part located in the +X direction with respect to the battery 17 and constitutes the battery holding part 100a.

[0066] As shown in FIGS. 7, 14, and 20, a restricting portion 101d is formed so as to extend in the -Z direction from the +Y direction end portion of the panel substrate support portion 101b. Due to the restricting portion 101d, the movement of the battery 17 in the +Y direction is restricted as shown in FIGS. 7 and 20. An elastic member 28 is provided between the restricting portion 101d and a first end portion 17a which is the +Y direction end portion of the battery 17, as also shown in FIG. 20. The elastic member 28 is also provided between the upper surface of the battery 17 and the panel substrate support portion 101b, as shown in FIG. 20.

[0067] Next, as shown in FIGS. 14 and 16, the light receiving portion substrate holding frame 103 has a base portion 103b forming a frame surface parallel to the X - Y plane and a light receiving portion substrate support portion 103a. The light receiving portion substrate support portion 103a is located in the +Z direction with respect to the base portion 103b. The light receiving portion substrate support portion 103a supports the light receiving portion substrate 80 from below as shown in FIGS. 7 and 20. The light receiving portion substrate 80 is fixed to the light receiving portion substrate support portion 103a by screws (not shown). The light receiving portion substrate holding frame 103 is an example of a first sub - frame for holding the light receiving portion substrate 80. The light receiving portion substrate 80 is in surface contact with the light receiving portion substrate support portion 103a, and thereby the heat of the light receiving portion substrate 80 is transmitted to the light receiving portion substrate holding frame 103.

[0068] The light receiving portion substrate holding frame 103 is supported from below by the light emitting portion substrate holding frame 104 as shown in FIG. 19. Reference numerals 104a and 104b indicate frame support portions which are the portions for supporting the light receiving portion substrate holding frame 103. The frame support portions 104a and 104b form a frame surface parallel to the X - Y plane and are in surface contact with the bottom surface of the light receiving portion substrate holding frame 103. Thereby, the heat of the light receiving portion substrate holding frame 103 is transmitted to the light emitting portion substrate holding frame 104. Since the light emitting portion substrate holding frame 104 is in contact with the main frame 101, the heat of the light receiving portion substrate holding frame 103 is transmitted to the main frame 101 via the light emitting portion substrate holding frame 104. That is, it can be said that the light receiving portion substrate holding frame 103 is indirectly in contact with the main frame 101.

[0069] [Other configurations of the color measurement device] Hereinafter, other configurations of the color measurement device 1 excluding the shutter unit 110 will be described. In FIG. 23, the outline of the battery 17 as viewed from the Z-axis direction is shown by a two-dot chain line, and the optical filter device 3, the PD substrate 5, the wireless communication unit 13, the battery control substrate 70, and the light receiving unit substrate 80 are shown by broken lines. In the present embodiment, the outlines of the battery control substrate 70 and the light receiving unit substrate 80 coincide with each other except for the -Y direction end when viewed from the Z-axis direction, and at the -Y direction end, the outline of the light receiving unit substrate 80 is slightly positioned in the +Y direction with respect to the outline of the battery control substrate 70. As described above, the optical filter device 3 and the PD substrate 5 constitute the incident light processing unit 2 that processes incident light. And as shown in FIG. 23, when viewed from the Z-axis direction, there is a portion where the incident light processing unit 2 and the battery 17 overlap.

[0070] More specifically, in the present embodiment, the incident light processing unit 2 is contained within the region of the battery 17 when viewed from the Z-axis direction. The band-pass filter 7 (see FIGS. 20 and 21) that constitutes the incident light processing unit 2 is not shown in FIG. 23, but as is clear from FIGS. 20 and 21, it is contained within the region of the PD substrate 5 when viewed from the Z-axis direction.

[0071] Since there is a portion where the incident light processing unit 2 and the battery 17 overlap when viewed from the Z-axis direction in this way, compared to a configuration in which the incident light processing unit 2 and the battery 17 are arranged in a direction intersecting the Z-axis direction, that is, the horizontal direction, the device dimensions in the X-axis direction and the Y-axis direction, which are the directions intersecting the Z-axis direction, that is, the device dimensions in the horizontal direction, can be suppressed. Also, in the present embodiment, the incident light processing unit 2, that is, the optical filter device 3 and the PD substrate 5, are contained within the region of the battery 17 when viewed from the Z-axis direction, so the device dimensions in the horizontal direction can be further suppressed.

[0072] Further, FIG. 24 shows the outline of the battery holding portion 100a (see FIGS. 7 and 14) that holds the battery 17 instead of the outline of the battery 17 shown in FIG. 23. That is, similarly from the perspective of the battery holding portion 100a, when viewed from the Z-axis direction, there is a portion where the incident light processing portion 2 and the battery holding portion 100a overlap. Therefore, compared with a configuration in which the incident light processing portion 2 and the battery holding portion 100a are arranged in a direction intersecting the Z-axis direction, that is, in the horizontal direction, the device dimensions in the horizontal direction can be suppressed.

[0073] In addition, in the present embodiment, the optical filter device 3 and the PD substrate 5, that is, the incident light processing portion 2, are within the region of the battery 17 or the battery holding portion 100a when viewed from the Z-axis direction. However, a part of the incident light processing portion 2 may be outside the region of the battery 17 or the battery holding portion 100a.

[0074] Also in the present embodiment, the battery 17 is within the X-axis direction region of the light receiving portion substrate 80 when viewed from the Z-axis direction as shown in FIG. 23. Also, the +Y direction end of the battery 17 is inside the +Y direction end of the light receiving portion substrate 80, and the -Y direction end of the battery 17 slightly protrudes from the -Y direction end of the light receiving portion substrate 80. However, the battery 17 may be configured to completely fit within the region of the light receiving portion substrate 80 when viewed from the Z-axis direction. By configuring it in that way, the device dimensions in the horizontal direction can be further suppressed.

[0075] Also in the present embodiment, as shown in FIG. 23, there is a portion where the display portion 15 and the light receiving portion substrate 80 overlap when viewed from the Z-axis direction.

[0076] The color measuring device 1 includes a light receiving portion substrate 80 provided with an incident light processing portion 2, a panel substrate 65 to which the LCD 67 is connected, a battery control substrate 70 to which the battery 17 is connected, and a light emitting portion substrate 85 provided with a light emitting portion 9 that emits light for measurement. And in the Z-axis direction, in order from the bottom surface 50f to the upper surface 50e of the device main body 50, the light emitting portion substrate 85, the light receiving portion substrate 80, and the panel substrate 65 are arranged to overlap as shown in FIG. 8. Also, the battery control board 70, the battery 17, and the panel board 65 are arranged so as to overlap in order from the bottom surface 50f to the upper surface 50e of the apparatus main body 50 in the Z-axis direction. And in this embodiment, the light emitting unit board 85, the light receiving unit board 80, the battery control board 70, the battery 17, and the panel board 65 are arranged so as to overlap in order from the bottom surface 50f to the upper surface 50e of the apparatus main body 50 in the Z-axis direction. With such a configuration, the apparatus dimensions in the X-axis direction and the Y-axis direction, which are directions intersecting the Z-axis direction, that is, the horizontal directions, can be suppressed. Note that, instead of providing the battery control board 70, the electronic components mounted on the battery control board 70 may be appropriately arranged on the panel board 65 or the light receiving unit board 80. Also, the configuration provided so as to overlap along the Z-axis direction may be any combination of two or three or more of the light emitting unit board 85, the light receiving unit board 80, the battery control board 70, the battery 17, and the panel board 65.

[0077] Also, the battery 17 has a shape extending in the Y-axis direction, which is the longitudinal direction of the apparatus. As shown in FIG. 20, the first end portion 17a, which is the +Y direction end portion of the battery 17, faces the front inner wall surface 51e of the main housing 51. Further, the second end portion 17b, which is the -Y direction end portion of the battery 17, faces the rear inner wall surface 51f of the main housing 51. That is, both end portions of the battery 17 in the Y-axis direction face the inner surfaces of the side walls in the Y-axis direction of the main housing 51. Thereby, compared with a configuration in which the battery 17 is disposed eccentrically in the Y-axis direction, the weight balance of the apparatus main body 50 in the Y-axis direction is excellent, and the handleability of the apparatus is improved. Note that in this embodiment, since the battery 17 is also at the center position of the apparatus in the X-axis direction as shown in FIGS. 21 and 22, the weight balance of the apparatus main body 50 in the X-axis direction is also excellent.

[0078] Also, as described with reference to FIGS. 3, 4, 21, and 22, recesses 51g that constitute the gripping portion 50g are formed in the main housing 51 on the right side surface 50b and the left side surface 50c of the apparatus main body 50, and are configured such that the user can easily and surely grip the apparatus main body 50. Here, the range indicated by the arrow Za in FIGS. 22 and 25 is the formation range of the recess 51g in the Z-axis direction, and as shown in FIG. 25, the recess 51g and the battery 17 have overlapping portions when viewed from the X-axis direction. As a result, the heavy battery 17 is configured to be close to the gripping position, improving the handleability of the apparatus.

[0079] Also, as shown in FIG. 22, in the right wall portion 51b and the left wall portion 51c of the main housing 51, the portion from the recess 51g to the bottom surface 50f side, that is, the -Z direction portion, is at the same position as a part of the LCD 67 in the X-axis direction. The portion from the recess 51g to the -Z direction of the right wall portion 51b and the left wall portion 51c is the portion in the -Z direction from the position indicated by the symbol Z4. As a result, the portion from the recess 51g to the -Z direction of the right wall portion 51b and the left wall portion 51c has an overlapping portion with the LCD 67 when viewed from the Z-axis direction as shown in FIG. 26. Thereby, as shown in FIG. 22, miniaturization in the X-axis direction of the apparatus portion in the -Z direction from the recess 51g can be achieved.

[0080] Also, as shown in FIG. 23, the color measuring apparatus 1 has a portion where the opening 21a and the operation portion 14 overlap when viewed from the Z-axis direction. Thereby, when the user aligns the opening 21a with the measurement portion of the measurement object 200 (see FIG. 1), alignment can be performed based on the position of the operation portion 14, that is, the opening 21a can be aligned with the measurement portion with a simple configuration. In particular, the color measuring apparatus 1 is configured as a handy type. As shown in FIG. 27, when the user operates the operation portion 14 with the fingertip Fs, the position of the fingertip Fa and the position of the opening 21a are close to each other, so that the position of the opening 21a becomes intuitively easy to understand.

[0081] Also, particularly in the present embodiment, when viewed from the Z-axis direction, the center position of the opening 21a and the center position of the determination button 54 coincide. As a result, the opening 21a can be more accurately aligned with the measurement site.

[0082] Also, as shown in FIG. 5, the determination button 54 is circular when viewed from the Z-axis direction, and cross buttons 60 for selecting various items are arranged around the determination button 54. The cross buttons 60 are provided with mark lines radiating outward from the center position of the determination button 54. These mark lines are composed of vertical lines 58a and 58b and horizontal lines 58c and 58d. This makes it easier to grasp the center position of the opening 21a when looking at the upper surface 50e of the device.

[0083] The operation unit 14 is configured to include a power button 55 and all buttons related to measurement on the upper surface 50e. As a result, the power button 55 and all buttons related to measurement can be easily visually recognized, and the device can be easily operated. Also, the upper surface 50e including the operation unit 14 is formed in a flat shape. Thereby, even when placed with the upper surface 50e facing down, it can be stably placed.

[0084] Also, as shown in FIG. 28, there is a portion where the panel substrate 65 and the battery 17 overlap when viewed from the Z-axis direction. FIG. 28 shows the outline of the panel substrate 65 instead of the outlines of the battery control substrate 70 and the light receiving unit substrate 80 shown in FIG. 23. By having a portion where the panel substrate 65 and the battery 17 overlap when viewed from the Z-axis direction, the device dimensions in the horizontal direction can be suppressed compared to a configuration where the panel substrate 65 and the battery 17 are arranged side by side in the X-axis direction or the Y-axis direction, that is, in the horizontal direction. Note that when viewed from the Z-axis direction, the battery 17 may be configured to fit within the area of the panel substrate 65. By configuring it in that way, the device dimensions in the horizontal direction can be further suppressed. Also, in the present embodiment, the wireless communication unit 13 fits within the area of the battery 17 when viewed from the Z-axis direction. However, a part of the wireless communication unit 13 may be within the area of the battery 17, or the entire wireless communication unit 13 may be outside the area of the battery 17.

[0085] FIG. 29 shows the outline of the battery holding part 100a (see FIGS. 7 and 14) that holds the battery 17 instead of the outline of the battery 17 shown in FIG. 28. That is, also from the viewpoint of the battery holding part 100a, when viewed from the Z-axis direction, since there is a portion where the panel substrate 65 and the battery holding part 100a overlap, compared with a configuration in which the panel substrate 65 and the battery holding part 100a are arranged in a direction intersecting the Z-axis direction, that is, in the horizontal direction, the device dimensions in the horizontal direction can be suppressed.

[0086] Also, as shown in FIG. 7, the wireless communication unit 13 is provided on the lower surface of the panel substrate 65, and in a state where the panel substrate 65 is supported by the panel substrate support part 101b, the wireless communication unit 13 is disposed inside the battery holding part 100a. By disposing the wireless communication unit 13 by utilizing the inside of the battery holding part 100a in this way, miniaturization of the device can be achieved. Here, although there is a possibility that heat radiation from the battery holding part 100a may adversely affect the wireless communication unit 13, a notch part 100b is formed in the battery holding part 100a (see also FIG. 14), and the wireless communication unit 13 is disposed at a position facing the notch part 100b. That is, when the battery holding part 100a is viewed from the -X direction, the wireless communication unit 13 is exposed through the notch part 100b. Thereby, it is possible to suppress heat radiation from the battery holding part 100a from adversely affecting the wireless communication unit 13.

[0087] Next, in the present embodiment, the battery 17 is provided between the operation unit 14 and the incident light processing unit 2 in the Z-axis direction as shown in FIG. 20. As described above, in the present embodiment, the incident light processing unit 2 includes the optical filter device 3 and the PD substrate 5. In FIG. 20, the position indicated by reference sign Z1 is the position of the PD substrate 5 that is located most in the +Z direction among the incident light processing unit 2, and is the position most in the +Z direction. The position indicated by reference sign Z3 is the position most in the -Z direction of the part constituting the operation unit 14, and specifically, is the Z-direction position of each contact (reference signs 54a, 61a, 62a in FIG. 20). And the position indicated by reference sign Z2 is the intermediate position between the position Z1 and the position Z3. Here, the battery 17 is provided with a thermistor 18 inside. The thermistor 18 is an example of a temperature detection unit. When the internal temperature of the battery 17 acquired by the thermistor 18 exceeds a predetermined allowable temperature, the MCU 10 (see FIG. 1) cuts off the power supply from the battery 17 to each component part.

[0088] And the thermistor 18 is located in the +Z direction from the position Z2 in the Z-axis direction, that is, it is arranged at a position closer to the operation unit 14 than the incident light processing unit 2. Here, in the present embodiment, the incident light processing unit 2 is one of the component parts of the colorimetric device 1 where a part of the supplied power is converted into heat, and its heat generation affects the temperature detection by the thermistor 18. In the incident light processing unit 2, heat generation is particularly significant on the PD substrate 5. However, since the thermistor 18 is arranged at a position closer to the operation unit 14 than the incident light processing unit 2, the influence of the heat generated in the incident light processing unit 2 on the thermistor 18 can be suppressed, and the temperature of the battery 17 can be detected more appropriately.

[0089] Also, as described above, the frame assembly 100 includes a battery holding portion 100a having a shape surrounding the battery 17 (see FIG. 7), so the heat generated from the battery 17 is well dissipated by the battery holding portion 100a.

[0090] Also, the thermistor 18 and the incident light processing unit 2 are provided at a position near one end in the Y-axis direction of the main body assembly 1a (see FIG. 7), that is, a position closer to the end in the +Y direction. The position closer to the end in the +Y direction means that it is located in the +Y direction from the middle position in the Y-axis direction of the main body assembly 1a. And at a position near one end in the Y-axis direction of the main body assembly 1a, that is, a position closer to the end in the +Y direction, a wired IF 12 which is a connection portion for wired communication with an external device is provided. And the wired IF 12 is located between the thermistor 18 and the incident light processing unit 2 in the Z-axis direction. Here, since the wired IF 12 is provided inside the opening (see FIG. 3), heat dissipation from the inside of the apparatus to the outside is promoted around the wired IF 12. And as shown in FIG. 20, since the wired IF 12 is positioned between the thermistor 18 and the incident light processing unit 2 in the Z-axis direction, the heat generated in the incident light processing unit 2 is dissipated from the wired IF 12 to the outside of the apparatus before reaching the thermistor 18. By this, it is possible to suppress the adverse effect of the heat generated in the incident light processing unit 2 on the thermistor 18.

[0091] Also, as shown in FIG. 20, the display unit 15 and the operation unit 14 are arranged along the Y-axis direction, and the thermistor 18 is arranged within the region of the operation unit 14 in the Y-axis direction. That is, although the LCD 67 constituting the display unit 15 is more likely to generate heat remarkably than the operation unit 14, in the configuration where the display unit 15 and the operation unit 14 are arranged along the Y-axis direction as described above, since the thermistor 18 is arranged within the region of the operation unit 14 in the Y-axis direction, it is possible to suppress the adverse effect of the heat generated in the LCD 67 on the thermistor 18.

[0092] Also, as shown in FIGS. 7, 14, and 15, the color measuring device 1 includes a light receiving unit substrate 80 and a light emitting unit substrate 85, and also includes a frame assembly 100 formed of a metal material. The frame assembly 100 includes a main frame 101 that forms the base of the apparatus, a light receiving unit substrate holding frame 103 that holds the light receiving unit substrate 80, and a light emitting unit substrate holding frame 104 that holds the light emitting unit substrate 85. And the light receiving unit substrate holding frame 103 and the light emitting unit substrate holding frame 104 are in direct or indirect contact with the main frame 101.

[0093] More specifically, in the present embodiment, each frame constituting the frame assembly 100 is formed of aluminum as described above. And the light emitting unit substrate holding frame 104 is in direct contact with the main frame 101 as described above, and the light receiving unit substrate holding frame 103 is in indirect contact with the main frame 101 via the light emitting unit substrate holding frame 104. With such a configuration, the heat generated in the light-receiving unit substrate 80 and the light-emitting unit substrate 85 is transmitted to the entire frame assembly 100, suppressing a local temperature rise inside the device and suppressing any adverse effects on color measurement results and the like.

[0094] In addition, in this embodiment, the light-receiving unit substrate holding frame 103 is in indirect contact with the main frame 101, but it may be in direct contact with the main frame 101. Also, in this embodiment, the light-emitting unit substrate holding frame 104 is in direct contact with the main frame 101, but it may be in indirect contact with the main frame 101. In addition, when the light-receiving unit substrate holding frame 103 or the light-emitting unit substrate holding frame 104 is in indirect contact with the main frame 101 via another member, it is preferable that the other member is a member having excellent thermal conductivity such as a metal material.

[0095] Further, since the main frame 101 has a main plate portion 101a forming a frame surface extending in the Y-axis direction and the Z-axis direction as shown in FIG. 18, in other words, a frame surface wide in the Y-Z plane, the surface area of the main frame 101 increases and the heat dissipation efficiency improves.

[0096] Also, since the frame assembly 100 includes a battery holding portion 100a having a shape surrounding the battery 17 as described above with reference to FIG. 7, the heat generated from the battery 17 is transmitted to the battery holding portion 100a and efficiently dissipated through the main frame 101 and the battery holding frame 102.

[0097] The battery holding portion 100a has a battery support portion 102a as a first wall portion that supports the battery 17 from below, and a panel substrate support portion 101b as a second wall portion that faces the battery support portion 102a and forms a wall portion on the upper surface side of the battery holding portion 100a. The battery holding portion 100a also has a sub-plate portion 101c as a third wall portion and a second frame portion 102c as a fourth wall portion that are positioned sandwiching the battery 17 in the X-axis direction. With such a configuration, the heat generated from the battery 17 is efficiently dissipated.

[0098] Also, in this embodiment, since the panel substrate 65 and the battery control substrate 70 are in direct contact with the main frame 101, the heat generated from the panel substrate 65 and the battery control substrate 70 is transmitted to the main frame 101 and dissipated well. Note that the panel substrate 65 and the battery control substrate 70 may be configured to be in indirect contact with the main frame 101 via other members. Here, it is preferable that the other members are members having excellent thermal conductivity such as a metal material.

[0099] [Configuration of the shutter unit] Next, the shutter unit 110 provided at the bottom of the apparatus main body 50 will be described. As shown in FIGS. 30 to 34, the shutter unit 110 is a unit body including a shutter holding member 111, a shutter member 112, and a link member 113. In this embodiment, the shutter holding member 111, the shutter member 112, and the link member 113 are formed of a resin material.

[0100] The link member 113 is rotatably connected to the shutter holding member 111 via a connecting shaft 114 having a central axis parallel to the X-axis direction. On the +X-direction and -X-direction side surfaces of the shutter holding member 111, a first guide shaft 121 and a second guide shaft 122 are provided. Also, on the +X-direction and -X-direction side surfaces of the link member 113, a third guide shaft 123 is provided.

[0101] At the +X-direction end and the -X-direction end of the opening forming member 21, as shown in FIGS. 32, 33, and 35, a first lower guide portion 21c, a second lower guide portion 21d, and a third lower guide portion 21e are formed along the Y-axis direction. Among these, the first lower guide portion 21c and the second lower guide portion 21d have a shape in which the -Y-direction end curves in the +Z-direction toward the -Y-direction. Also, the third lower guide portion 21e is formed in an inclined shape that slightly goes in the -Z-direction toward the -Y-direction.

[0102] In the bottom housing 53, at the +X-direction end and the -X-direction end, a first upper guide portion 53c is formed so as to sandwich the first guide shaft 121 between it and the above-described first lower guide portion 21c as shown in FIG. 35. Note that FIG. 35 shows the first upper guide portion 53c located at the +X-direction end. Similarly, in the bottom housing 53, at the +X-direction end and the -X-direction end, a second upper guide portion 53d is formed so as to sandwich the second guide shaft 122 between it and the above-described second lower guide portion 21d. Note that FIG. 35 shows the second upper guide portion 53d located at the +X-direction end. Also similarly, in the bottom housing 53, at the +X-direction end and the -X-direction end, a third upper guide portion 53e is formed so as to sandwich the third guide shaft 123 between it and the above-described third lower guide portion 21e. Note that FIG. 35 shows the third upper guide portion 53e located at the +X-direction end.

[0103] In this way, the first guide shaft 121, the second guide shaft 122, and the third guide shaft 123 are sandwiched in the Z-axis direction between the opening forming member 21 and the bottom housing 53, and are guided in the Y-axis direction by the opening forming member 21 and the bottom housing 53. Among these, since the first guide shaft 121 and the second guide shaft 122 are provided on the shutter holding member 111, the movement locus of the shutter holding member 111 is defined by the first lower guide portion 21c and the first upper guide portion 53c, and the second lower guide portion 21d and the second upper guide portion 53d. Also, since the third guide shaft 123 is provided on the link member 113, the movement locus of the link member 113 is defined by the third lower guide portion 21e and the third upper guide portion 53e, and the connecting shaft 114 in the shutter holding member 111.

[0104] Furthermore, the +Y direction movement limit of the shutter unit 110, i.e., the closed position, is defined by the first guide shaft 121 abutting against the movement restricting portion 53f formed on the bottom housing 53. Also, the -Y direction movement limit of the shutter unit 110, i.e., the open position, is defined by the first guide shaft 121 abutting against the movement restricting portion 21f formed on the opening forming member 21. In the present embodiment, the second guide shaft 122 and the third guide shaft 123 do not define the Y direction movement limit of the shutter unit 110.

[0105] Next, as shown in FIGS. 31, 33, 34, 36, and 37, the -Z direction surface of the portion where the opening 21a is formed in the opening forming member 21 is denoted by reference numeral 21g. Hereinafter, this will be referred to as the shutter facing surface 21g. The shutter facing surface 21g is a flat surface forming an annular shape in plan view. As shown in FIG. 34, the shutter facing surface 21g is located slightly in the +Z direction from the bottom surface 50f, that is, it does not protrude in the -Z direction from the bottom surface 50f. And among the shutter unit 110 in the closed position, the shutter holding member 111 will protrude in the -Z direction from the bottom surface 50f as shown in FIG. 34. Also, among the shutter unit 110 in the closed position, the link member 113 does not protrude at least in the -Z direction from the shutter holding member 111, and most of it does not protrude from the bottom surface 50f.

[0106] Since the movement locus of the shutter holding member 111 is defined by the first lower guide portion 21c and the first upper guide portion 53c, and the second lower guide portion 21d and the second upper guide portion 53d as shown in FIG. 35, when the shutter holding member 111 moves from the closed position toward the open position, as is clear from FIG. 35, it will move largely in the +Z direction in the latter half of the displacement while being displaced in the -Y direction. As a result, when the shutter unit 110 is in the open position, the shutter holding member 111 will not protrude in the -Z direction from the bottom surface 50f as shown in FIGS. 31 and 20.

[0107] When the shutter holding member 111 moves in the +Z direction, the link member 113 rotates relative to the shutter holding member 111 as shown by the change from FIG. 36 to FIG. 37 via the connecting shaft 114. Even when the shutter unit 110 is in the open position, as shown in FIG. 37, the link member 113 does not protrude in the -Z direction from the shutter holding member 111. Also, when the shutter unit 110 is in the open position, the entire link member 113 does not protrude in the -Z direction from the bottom surface 50f as shown in FIG. 20.

[0108] Next, as shown in FIG. 15, bearing portions 105c are formed in the bottom frame 105 at intervals in the X-axis direction. And as shown in FIGS. 32, 34, 36, and 37, a spring hanging shaft 115 is pivotally supported by the bearing portion 105c. One end of a torsion spring 117, which is an example of a spring member, is rotatably fixed to the spring hanging shaft 115. The tip of one end of the torsion spring 117 is formed in a coil shape so as to be able to pass through the spring hanging shaft 115. The other end of the torsion spring 117 is rotatably fixed to a third guide shaft 123 provided on the link member 113. The tip of the other end of the torsion spring 117 is formed in a coil shape so as to be able to pass through the third guide shaft 123. Thus, the torsion spring 117 can rotate in the Y-Z plane, in other words, can change its posture.

[0109] When the shutter unit 110 is in the closed position, as shown in FIG. 34, the external force F applied by the torsion spring 117 to the third guide shaft 123, that is, the shutter unit 110, includes a -Z direction component and a +Y direction component. Thereby, the torsion spring 117 presses the shutter unit 110 in the +Y direction as indicated by the arrow Fy, that is, presses the shutter unit 110 toward the closed position, whereby the shutter unit 110 is held in the closed position.

[0110] FIG. 36 shows a state where the shutter unit 110 has moved a predetermined amount in the -Y direction from the closed position. The pressing force F with which the torsion spring 117 presses the shutter unit 110 decreases in the +Y direction component as the shutter unit 110 is displaced from the closed position to the neutral position described later, and eventually the component force in the Y-axis direction becomes zero and only the component in the -Z direction remains. At this time, the torsion spring 117 is in a state where it does not press the shutter unit 110 in either the +Y direction or the -Y direction. Hereinafter, the position of the shutter unit 110 in this state is referred to as the neutral position. Of course, when the shutter unit 110 is displaced from the open position to the neutral position, the component of the pressing force F in the Y-axis direction also decreases and eventually becomes zero.

[0111] When the shutter unit 110 is displaced in the -Y direction from the neutral position, that is, when it is displaced toward the open position, the pressing force F with which the torsion spring 117 presses the shutter unit 110 comes to include a -Y direction component, and this -Y direction component increases as the shutter unit 110 is displaced toward the open position. As a result, as shown in FIG. 37, when the shutter unit 110 is in the open position, the pressing force F with which the torsion spring 117 presses the shutter unit 110 includes the pressing force Fy in the -Y direction component, and the shutter unit 110 is held in the open position.

[0112] Next, on the +Z direction side of the shutter holding member 111, a shutter member 112 is provided. On the -Z direction side of the shutter member 112, a cylindrical portion 112e is formed as shown in FIGS. 34, 36, 37, and 39. The shutter holding member 111 is formed with a recess 111c for receiving the cylindrical portion 112e (see also FIG. 40).

[0113] Also, on the +Z direction side of the shutter member 112, a white plate 125 serving as a reflection reference surface is provided as shown in FIG. 43. The white plate 125 exhibits white so that the reflectance is close to 100% in order to obtain a reflection reference value. The white plate 125 is located in the central region in the planar direction of the shutter member 112, that is, in the X-Y plane. Here, the fact that the white plate 125 is located in the central region in the planar direction of the shutter member 112 means that the central position in the planar direction of the shutter member 112 is included within the range of the white plate 125. The central position in the planar direction of the shutter member 112 is the central position in the Y-axis direction and the X-axis direction of the shutter member 112, and in this embodiment, it generally coincides with the optical axis CL or is at least in the vicinity of the optical axis CL.

[0114] The shutter member 112 is provided so as to be displaceable with respect to the shutter holding member 111 in the Z-axis direction, that is, in the direction of approaching and separating from the opening 21a. More specifically, as shown in FIGS. 38 and 39, protrusions 112d are provided at intervals in the Y-axis direction on the +X-direction and -X-direction side surfaces of the shutter member 112. On the other hand, openings 111b for receiving the protrusions 112d are provided at intervals in the Y-axis direction on the +X-direction and -X-direction side surfaces of the shutter holding member 111.

[0115] The size of the opening 111b in the Z-axis direction is larger than the size of the protrusion 112d in the Z-axis direction, whereby the protrusion 112d can move in the Z-axis direction while being inserted into the opening 111b. Thereby, the shutter member 112 is held by the shutter holding member 111 so as to be movable in the Z-axis direction.

[0116] As shown in FIG. 40, the shutter holding member 111 is provided with a leaf spring 118 as a pressing member that presses the shutter member 112 in the +Z direction, that is, toward the opening 21a. The leaf spring 118 includes a plurality of pressing portions that press the shutter member 112, and specifically includes three pressing portions 118a. The plurality of pressing portions 118a are arranged at substantially equal intervals at positions along the periphery of the opening 21a.

[0117] When the shutter unit 110 is in the closed position, as shown in FIG. 34, the contact surface 112a of the shutter member 112 that faces the shutter facing surface 21g adheres to the shutter facing surface 21g by the pressing force of the leaf spring 118. The contact surface 112a forms an annular shape around the opening 21a, that is, along the shutter facing surface 21g (see FIG. 43). When the contact surface 112a abuts against the shutter facing surface 21g, the opening 21a is closed, and the entry of dust and the like into the interior of the device through the opening 21a is suppressed.

[0118] Next, as shown in FIGS. 31, 33, 41, and 42, first protruding ribs 21b are formed along the Y-axis direction on both sides of the shutter facing surface 21g in the X-axis direction. The first protruding rib 21b is a rib that protrudes from the opening forming member 21 in the -Z direction. Further, as shown in FIG. 43, second protruding ribs 112b are formed along the Y-axis direction on both sides of the contact surface 112a of the shutter member 112 in the X-axis direction. The second protruding rib 112b is a rib that protrudes from the shutter member 112 toward the opening forming member 21.

[0119] The second protruding rib 112b is formed at a position where it can abut against the first protruding rib 21b. When the shutter unit 110 is in the closed position, as shown in FIG. 41, the second protruding rib 112b is located in the +Y direction with respect to the first protruding rib 21b and does not abut against the first protruding rib 21b. An inclined surface 112c that slopes from the -Y direction toward the -Z direction is formed at the -Y direction end of the second protruding rib 112b. Further, an inclined surface 21h that slopes from the +Y direction toward the +Z direction is formed at the +Y direction end of the first protruding rib 21b. When the shutter unit 110 is in the closed position, the inclined surface 112c and the inclined surface 21h face each other.

[0120] When the shutter unit 110 is displaced from this state toward the open position, the second protruding rib 112b abuts against the first protruding rib 21b, and as shown by the change from FIG. 41 to FIG. 42, the second protruding rib 112b overlaps with the first protruding rib 21b in the Z-axis direction. As a result, the shutter member 112 moves in the -Z direction against the pressing force of the leaf spring 118, and a gap is formed between the shutter opposing surface 21g and the contact surface 112a as shown in FIG. 36. In this way, the first protruding rib 21b and the second protruding rib 112b constitute a moving means 119 for moving the shutter member 112 in a direction in which the shutter member 112 separates from the opening forming member 21 when the shutter unit 110 in the closed position is displaced toward the open position. As a result, wear of the shutter opposing surface 21g can be minimized.

[0121] Next, as shown in FIGS. 43 to 45, a window portion 112f is formed in the shutter member 112, and the magnet 127 is provided so as to be exposed through the window portion 112f. The magnet 127 is fixed to the shutter holding member 111 by an adhesive or a double-sided tape. A magnetic sensor 128 is provided on the lower surface of the light emitting portion substrate 85.

[0122] When the shutter unit 110 is in the open position, as shown in FIG. 44, the magnet 127 is in a position overlapping with the magnetic sensor 128 in the Y-axis direction. This state is a state where the linear distance between the magnet 127 and the magnetic sensor 128 is the shortest. On the other hand, when the shutter unit 110 is in the closed position, as shown in FIG. 45, the linear distance between the magnet 127 and the magnetic sensor 128 becomes longer than when it is in the open position. This state is a state where the linear distance between the magnet 127 and the magnetic sensor 128 is the longest. With such a configuration, the magnetic sensor 128 can be disposed at a position away from the opening 21a, and an increase in the size of the device due to disposing the magnetic sensor 128 near the opening 21a can be suppressed.

[0123] The magnetic sensor 128 is a magnetic sensor that changes the detection signal according to the magnetic intensity. When the shutter unit 110 is in the open position, it sends a high detection signal to the MCU 10 (see FIG. 1). Also, when the shutter unit 110 is in the closed position, the magnetic sensor 128 sends a low detection signal to the MCU 10 (see FIG. 1). That is, the magnetic sensor 128 is a detection means that changes the detection signal according to the displacement of the shutter unit 110. Thereby, the MCU 10 can detect whether the shutter unit 110 is in the closed position or the open position.

[0124] As described above, the shutter unit 110 includes a shutter member 112 that closes the opening 21a when in the closed position, a shutter holding member 111 that holds the shutter member 112 so that the shutter member 112 can be displaced in a direction approaching and separating from the opening 21a, and a leaf spring 118 that is an example of a pressing member that presses the shutter member 112 toward the opening 21a. Thereby, even if manufacturing errors, assembly errors, or wear due to use of parts occur, it is possible to suppress the generation of a gap between the shutter member 112 and the opening 21a by pressing the shutter member 112 toward the opening 21a. As a result, it is possible to satisfactorily suppress the intrusion of dust and the like into the opening 21a.

[0125] Also, since the leaf spring 118 presses the shutter member 112 at a plurality of pressing portions 118a, that is, at a plurality of positions along the periphery of the opening 21a, it is possible to suppress the shutter member 112 from being biased and pressed at a specific position of the opening 21a, and the opening 21a can be satisfactorily closed by the shutter member 112.

[0126] When the shutter unit 110 in the closed position is displaced toward the open position, a moving means 119 is provided for moving the shutter member 112 in a direction away from the opening forming member 21. Therefore, wear between the shutter facing surface 21g, which is the part of the opening forming member 21 that forms the opening 21a, and the contact surface 112a, which is the part of the shutter member 112 that closes the opening 21a, is suppressed. As a result, a gap is prevented from occurring between the opening 21a and the shutter member 112, and the risk of dust or the like entering can be suppressed.

[0127] The moving means 119 includes a first protruding rib 21b formed on the opening forming member 21 and protruding toward the shutter member 112, and a second protruding rib 112b formed on the shutter member 112 and protruding toward the opening forming member 21. When the shutter unit 110 is in the closed position, the first protruding rib 21b is in a non-contact state with the second protruding rib 112b, and when the shutter unit 110 in the closed position is displaced toward the open position, the second protruding rib 112b rides on the first protruding rib 21b, causing the shutter member 112 to move in a direction away from the opening forming member 21. With such a configuration, the moving means 119 can be configured at low cost.

[0128] The shutter unit 110 also includes a link member 113 that is located on the open position side of the shutter holding member 111 and is connected to the shutter holding member 111 so as to be relatively rotatable. The shutter holding member 111 protrudes from the bottom surface 50f when the shutter unit 110 is in the closed position and does not protrude from the bottom surface 50f when the shutter unit 110 is in the open position. The link member 113 maintains a state of not protruding from the bottom surface 50f more than the shutter holding member 111 regardless of the position of the shutter unit 110 by rotating relative to the shutter holding member 111. Thereby, compared with a configuration in which the shutter holding member 111 and the link member 113 are integrated, it is possible to reduce the size of the device particularly when the shutter unit 110 is in the closed position.

[0129] It also includes a torsion spring 117 that presses the link member 113 toward the open position and the closed position, and the posture of the torsion spring 117 changes as the shutter unit 110 is displaced. Thereby, when the shutter unit 110 is on the side of the closed position from the neutral position, the torsion spring 117 presses the link member 113 toward the closed position (see FIG. 34). Further, when the shutter unit 110 is on the side of the open position from the neutral position, the torsion spring 117 presses the link member 113 toward the open position (see FIGS. 36 and 37). With such a configuration, means for maintaining the shutter unit 110 in the closed position and the open position can be configured at low cost.

[0130] Incidentally, FIG. 46 schematically shows the position of the shutter unit 110. The position Ya1 indicates the closed position of the shutter unit 110, the position Ya2 indicates the open position, and the position Yac indicates the neutral position. The reference sign A1 indicates the movement range of the shutter unit 110 between the closed position Ya1 and the neutral position Yac, and the reference sign A2 indicates the movement range of the shutter unit 110 between the open position Ya2 and the neutral position Yac.

[0131] Here, due to friction or the like between the first guide shaft 121, the second guide shaft 122, and the third guide shaft 123 described with reference to FIG. 35, and the opening forming member 21 and the bottom housing 53, even if the shutter unit 110 is slightly on the side of the closed position Ya1 from the neutral position Yac, the shutter unit 110 may not move and may maintain a stopped state. Similarly, even if the shutter unit 110 is slightly on the side of the open position Ya2 from the neutral position Yac, the shutter unit 110 may not move and may maintain a stopped state. In FIG. 46, the range indicated by the range K is an area where the shutter unit 110 maintains a stopped state in this way. Hereinafter, this will be referred to as the stop area K of the shutter unit 110.

[0132] Next, as described above, a white plate 125 that forms a reflection reference surface as a reference for reflectance is provided at a position facing the opening 21a in the shutter member 112. Since the shutter member 112 is configured to be pressed toward the opening 21a by the leaf spring 118, the position and orientation of the white plate 125 are less likely to vary, and an appropriate reference value can be obtained.

[0133] In addition, the shutter unit 110 and the related configurations can be modified as shown in FIGS. 47 to 50. In FIGS. 47 to 50, the same components as those already described are denoted by the same reference numerals, and duplicate descriptions will be avoided hereinafter. In FIGS. 47 and 48, the shutter unit 110A includes a shutter holding member 111A, a link member 113A, and a second link member 130. The shutter holding member 111A and the link member 113A are relatively rotatably connected via a connecting shaft 114. The link member 113A and the second link member 130 are relatively rotatably connected via a second connecting shaft 131.

[0134] A rotating shaft 132 parallel to the X-axis direction is supported by the opening forming member 21A, and the second link member 130 is provided so as to be rotatable in the Y-Z plane about this rotating shaft 132. A torsion spring 133 is provided on the opening forming member 21A at intervals in the X-axis direction. One end of the torsion spring 133 is rotatably attached to a part of the opening forming member 21A, and the other end of the torsion spring 133 is attached to the second link member 130.

[0135] FIG. 47 shows the state where the shutter unit 110A is in the closed position, and FIG. 48 shows the state where the shutter unit 110A is in the open position. As shown by the change from FIG. 47 to FIG. 48, or the change from FIG. 48 to FIG. 47, as the shutter unit 110A is displaced, the shutter holding member 111A and the link member 113A rotate relative to each other, and the link member 113A and the second link member 130 rotate relative to each other. At this time, the torsion spring 133 changes its posture in the same manner as the torsion spring 117 (see FIG. 32) described above. As a result, when the shutter unit 110A is between the closed position and the neutral position, the torsion spring 133 presses the shutter unit 110A toward the closed position. Also, when the shutter unit 110A is between the open position and the neutral position, the torsion spring 133 presses the shutter unit 110A toward the open position.

[0136] Next, in FIGS. 49 and 50, the shutter unit 110B includes a shutter holding member 111B and a link member 113B. The shutter holding member 111B and the link member 113B are relatively rotatably connected via a first connecting portion 140. A second connecting portion 141 extending along the X-axis direction is formed on the link member 113B. A connecting member 142 is slidably fitted to the second connecting portion 141 in the X-axis direction.

[0137] A rotating shaft 144 is integrally formed on the opening forming member 21B, and an arm member 143 is provided on the rotating shaft 144 so as to be rotatable in the X-Y plane. The arm member 143 and the connecting member 142 are connected so as to be relatively rotatable via a link shaft 143a having a central axis parallel to the Z-axis direction. And a torsion spring (not shown) that generates a spring force is provided between the opening forming member 21B and the arm member 143 in the +Z direction with respect to the arm member 143.

[0138] FIG. 49 shows a state where the shutter unit 110B is in the closed position, and FIG. 50 shows a state where the shutter unit 110B is in the open position. As shown by the change from FIG. 49 to FIG. 50, or the change from FIG. 50 to FIG. 49, the shutter holding member 111B and the link member 113B rotate relatively as the shutter unit 110B is displaced. Also, the arm member 143 rotates, and accordingly, the arm member 143 and the connecting member 142 rotate relatively. At this time, the connecting member 142 slides along the X-axis direction on the second connecting portion 141.

[0139] As the arm member 143 rotates, a torsion spring (not shown) located in the +Z direction with respect to the arm member 143 changes its posture. Thus, when the shutter unit 110B is between the closed position and the neutral position, the torsion spring presses the shutter unit 110B toward the closed position. Also, when the shutter unit 110B is between the open position and the neutral position, the torsion spring presses the shutter unit 110B toward the open position. The shutter unit 110 and the related configurations can be modified as described above.

[0140] Next, as described above, the color measuring device 1 includes a magnetic sensor 128 that changes a detection signal according to the displacement of the shutter unit 110. Thereby, the position of the shutter unit 110 can be grasped, and appropriate control according to the position of the shutter unit 110 can be performed.

[0141] Also, since the magnetic sensor 128 is a sensor that changes a detection signal according to the magnetic intensity, it is not necessary to provide a dedicated opening for transmitting detection light like an optical sensor, and a decrease in the airtightness of the device due to the formation of an extra opening can be avoided. However, as a detection means for detecting the position of the shutter unit 110, it is also possible to use other types of non-contact sensors such as an optical sensor, a capacitance-type proximity sensor, an inductive proximity sensor, or a contact-type sensor.

[0142] Hereinafter, the control performed by the MCU10 (see FIG. 1), which is a control unit that receives a detection signal from the magnetic sensor 128, will be described with reference to FIGS. 51 to 53. In FIG. 51, when the power button 55 (see FIG. 5 etc.) is pressed while the power is on, that is, when a power-off command for the device is received (Yes in step S101), if the shutter unit 110 is in the closed position (Yes in step S102), the process proceeds to the power-off process for the device (step S103). On the other hand, if the shutter unit 110 is in the open position (No in step S102), the transition to power-off is postponed. And in this embodiment, an alert indicating that the shutter unit 110 is in the open position is displayed on the display unit 15 (see FIG. 5 etc.) (step S104).

[0143] Thereby, the device is not powered off while the shutter unit 110 is in the open position, and it is possible to prevent dust etc. from entering the inside of the device through the opening 21a while the device is in the powered-off state. Also, since an alert indicating that the shutter unit 110 is in the open position is displayed on the display unit 15, usability is improved. Note that the alert indicating that the shutter unit 110 is in the open position can be, for example, a message display such as "The shutter is open. Please close it."

[0144] Next, in FIG. 52, when the MCU 10 determines the timing to acquire the reference value using the white plate 125 (see FIG. 43 etc.) (Yes in step S201), it determines whether the shutter unit 110 is in the closed position (step S202). As a result, if the shutter unit 110 is in the closed position (Yes in step S202), the reference value acquisition process is executed (step S203). On the other hand, if the shutter unit 110 is in the open position (No in step S202), the acquisition of the reference value is postponed. In this case, in this embodiment, an alert indicating that the shutter unit 110 is in the open position is displayed on the display unit 15 (see FIG. 5 etc.) (step S204). Thereby, the reference value can be appropriately acquired using the white plate 125. Note that the timing to acquire the reference value includes, for example, when the power button 55 (see FIG. 5 etc.) is pressed from the powered-off state, that is, when a power-on command for the device is received, or when a predetermined time has elapsed in the powered-on state of the device.

[0145] Next, in FIG. 53, when the determination button 54 (see FIG. 5 etc.) is pressed, that is, when the color measurement execution command is received (Yes in step S301), if the shutter unit 110 is in the open position (Yes in step S302), the color measurement process is executed (step S303). On the other hand, if the shutter unit 110 is in the closed position (No in step S302), the transition to power-off is postponed. And in this embodiment, an alert indicating that the shutter unit 110 is in the closed position is displayed on the display unit 15 (see FIG. 5 etc.) (step S304). By such control, an appropriate color measurement value can be obtained. Incidentally, when the color measurement execution command is received (Yes in step S301), if the shutter unit 110 is in the open position (Yes in step S302), the color measurement process is executed (step S303), and if the shutter unit 110 is in the open position (No in step S302), after obtaining a reference value using the white plate 125, the process may proceed to the process of step S304.

[0146] Also in FIG. 46, in the displacement region (A1 + A2) of the shutter unit 110, the region B1 where the magnetic sensor 128 sends out a detection signal indicating the closed position of the shutter unit 110 is set by providing a margin M from the neutral position Yac to the closed position Ya1 side. In FIG. 46, the position Ybc indicates the switching position of the detection signal of the magnetic sensor 128. In the region B1, a detection signal indicating that the shutter unit 110 is in the closed position is sent out, and in the region B2, a detection signal indicating that the shutter unit 110 is in the open position is sent out. Particularly in this embodiment, the region B1 is set further on the closed position Ya1 side than the stop region K of the shutter unit 110 described above. Thus, when the magnetic sensor 128 sends out a detection signal indicating the closed position of the shutter unit 110, the shutter unit 110 will surely be in the closed position. As a result, there is no risk of the shutter unit 110 being judged to be in the closed position even though it is in an intermediate position, and thus the acquisition of the reference value using the white plate 125 can be surely performed.

[0147] 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 it goes without saying that those are also included in the scope of the present invention. For example, in the above-described embodiment, the colorimeter 1 incorporates the battery 17, but the battery 17 may be configured to be removable, that is, the colorimeter 1 may be configured not to incorporate the battery 17. Also in that case, the battery 17 may be a primary battery that does not perform repeated charge and discharge.

[0148] Also, in the present embodiment, the incident light processing unit 2 is configured to include an optical filter device 3 and a light receiving unit 4. The optical filter device 3 is a wavelength-variable Fabry-Perot etalon that transmits a predetermined wavelength component of the incident light, but is not limited thereto. For example, as a spectroscopic method, a spectroscopic method using a diffraction grating may be used. Also, as a colorimetric principle, a device configuration that employs a stimulus value direct reading method for directly measuring three stimulus values that are the basis of colors may be used. Also, in the present embodiment, an LED is used as the light emitting element used in the light emitting unit 9, but it is not limited thereto, and for example, a xenon lamp may be used.
