Abstract

A color measurement apparatus includes an opening portion forming member that is a member in which an opening portion for causing light arriving from a measurement target to enter inside the apparatus is formed, and that is arranged on a bottom surface at a time of measurement performed by the apparatus, the opening portion for causing the light arriving from the measurement target to enter inside the apparatus, an incident light processing portion that processes light incident through the opening portion, and a battery that supplies power to the incident light processing portion, in which in a view from a first direction that is a vertical direction intersecting with the bottom surface and an upper surface which is a surface on an opposite side from the bottom surface, the incident light processing portion and the battery have an overlapping part.

Claims (37)

1. A color measurement apparatus comprising:

an opening portion former in which an opening portion for causing light arriving from a measurement target to enter inside the apparatus is formed, and that is arranged on a bottom surface of the color measurement apparatus;

an incident light sensor that processes light incident through the opening portion former and is positioned above the opening portion former in a first direction that is a vertical direction intersecting with the bottom surface and an upper surface which is a surface on an opposite side from the bottom surface;

a decision button that executes color measurement, wherein a center of the decision button coincides with a center of the opening portion along the first direction; and

a battery that supplies power to the incident light sensor and is positioned above the incident light sensor in the first direction, wherein

in a view from the first direction, the incident light sensor, the battery, and the opening portion have an overlapping part.

2. The color measurement apparatus according to claim 1 , wherein

in a view from the first direction, the incident light sensor falls within a region of the battery.

3. The color measurement apparatus according to claim 1 , wherein the incident light sensor includes

a variable wavelength optical filter that transmits a predetermined wavelength component of incident light, and

a light receiver that receives light transmitted through the optical filter.

4. The color measurement apparatus according to claim 3 , wherein the optical filter is a Fabry-Perot etalon.

5. The color measurement apparatus according to claim 1 , further comprising:

a first circuit substrate that includes the incident light sensor;

a second circuit substrate that is positioned on the upper surface and to which a display portion which performs various kinds of display is coupled;

a third circuit substrate to which the battery is coupled; and

a fourth circuit substrate that includes a light emission portion which emits light for measurement, wherein

in order from the bottom surface toward the upper surface in the first direction, the fourth circuit substrate, the first circuit substrate, and the second circuit substrate are arranged in an overlapping manner.

6. The color measurement apparatus according to claim 1 , further comprising:

a first circuit substrate that includes the incident light sensor;

a second circuit substrate that is positioned on the upper surface and to which a display portion which performs various kinds of display is coupled;

a third circuit substrate to which the battery is coupled; and

a fourth circuit substrate that includes a light emission portion which emits light for measurement, wherein

in order from the bottom surface toward the upper surface in the first direction, the third circuit substrate, the battery, and the second circuit substrate are arranged in an overlapping manner.

7. The color measurement apparatus according to claim 6 , wherein

the battery has a shape that extends in a second direction which is a direction intersecting with the first direction and is a longitudinal direction of the apparatus in a view from the first direction, and

both end portions of the battery in the second direction face a side wall inner surface, in the second direction, of a casing that forms an outline of the apparatus.

8. The color measurement apparatus according to claim 7 , wherein

the casing includes a recessed portion for grip on a side wall in a third direction that is a direction orthogonal to the second direction and is a short direction of the apparatus in a view from the first direction, and

the battery and the recessed portion have an overlapping part in a view from the third direction.

9. The color measurement apparatus according to claim 8 , wherein

a part of a side wall of the casing in the third direction on the bottom surface side from the recessed portion and the display portion have an overlapping part in a view from the first direction.

10. A color measurement apparatus comprising:

an opening portion former in which an opening portion for causing light arriving from a measurement target to enter inside the apparatus is formed, and that is arranged on a bottom surface of the color measurement apparatus;

an incident light sensor that processes light incident through the opening portion former and is positioned above the opening portion former in a first direction that is a vertical direction intersecting with the bottom surface and an upper surface which is a surface on an opposite side from the bottom surface;

a decision button that executes color measurement, wherein a center of the decision button coincides with a center of the opening portion along the first direction; and

a battery holding portion that holds a battery which supplies power to the incident light sensor and is positioned above the incident light sensor in the first direction, wherein in a view from a first direction that is the vertical direction, the incident light sensor, the battery, and the opening portion have an overlapping part.
