Abstract

A biological body inspection apparatus includes a measurement module that acquires an amount of light having a wavelength under measurement contained in light incident on the measurement module and an enclosure that accommodates the measurement module and has a window that transmits light traveling toward the measurement module. An adhesive member is provided on a surface of the enclosure at least in an area thereof that surrounds the window. The adhesive member has a light blocking section that is located in an area outside the window and surrounds the window in a plan view in the direction along the optical axis of the light traveling toward the measurement module and blocks light that belongs to a measurement wavelength region within which at least the wavelength under measurement is present.

Claims

1. A spectrometric apparatus comprising:

a measurement module that acquires an amount of light having a wavelength under measurement contained in light incident on the measurement module; and

an enclosure that accommodates the measurement module and has a window that transmits light traveling toward the measurement module,

wherein an adhesive member is provided on a surface of the enclosure at least in an area thereof that surrounds the window, and

the adhesive member has a light blocking section that is located in the area but in an area outside the window and surrounds the window in a plan view in a direction along an optical axis of the light traveling toward the measurement module and blocks light that belongs to a measurement wavelength region within which at least the wavelength under measurement is present.

2. The spectrometric apparatus according to claim 1,

wherein the light blocking section is provided in an area inside an outer circumferential edge of the adhesive member in the plan view.

3. The spectrometric apparatus according to claim 2,

wherein the light blocking section is provided along an outer edge of the window in the plan view.

4. The spectrometric apparatus according to claim 1,

wherein the adhesive member has a light transmissive section that transmits at least the light that belongs to the measurement wavelength region, and the light blocking section and the light transmissive section are formed integrally with each other.

5. The spectrometric apparatus according to claim 1,

wherein the adhesive member has a light transmissive section that is provided in a position where the light transmissive section overlaps with the window in the plan view and transmits at least the light that belongs to the measurement wavelength region,

the window has an opening provided in the enclosure and a light transmissive member disposed in the opening, and

the light transmissive section has a refractive index that differs from a refractive index of the light transmissive member by an amount smaller than or equal to a predetermined threshold.

6. The spectrometric apparatus according to claim 1,

further comprising a circuit substrate provided with a controller that controls the spectrometric apparatus,

wherein the light blocking section contains carbon-based conductive fillers and hence has conductivity, and

the enclosure has a wiring line that achieves conduction between the light blocking section and the circuit substrate.

7. The spectrometric apparatus according to claim 1,

wherein the measurement module includes

a light source section that irradiates a subject with light,

a spectroscopic filter capable of selecting light of a predetermined wavelength from light from the subject and outputting the selected light and further capable of changing the wavelength of the light to be outputted, and

a light reception section that receives the light from the spectroscopic filter.

8. A storage case that accommodates a plurality of adhesive sheets each of which is formed of an adhesive member on which a peelable sheet is stuck, the adhesive member disposed on at least part of a surface of a spectrometric apparatus that acquires an amount of light having a wavelength under measurement contained in light incident on the spectrometric apparatus, the spectrometric apparatus including,

a measurement module that acquires the amount of light, and

an enclosure that accommodates the measurement module and has a window that transmits light traveling toward the measurement module,

an area which surrounds at least the window and in which the adhesive member is disposed, set on a surface of the enclosure, and

the adhesive member having a light blocking section that is located in the area but in an area outside the window and surrounds the window in a plan view in a direction along an optical axis of the light traveling toward the measurement module and blocks light that belongs to a measurement wavelength region within which at least the wavelength under measurement is present,

the storage case comprising:

a bottom section having a placement surface on which the adhesive sheet is placed; and

a sidewall section that continuously extends from a peripheral portion of the placement surface and is provided along a direction in which the adhesive sheet approaches or separates from the bottom section,

wherein the sidewall section includes

a first restricting section that comes into contact with at least part of an outer circumferential edge of the peelable sheet to restrict the position of the peelable sheet in a plane perpendicular to the approaching/separating direction, and

a second restricting section that comes into contact with at least part of an outer circumferential edge of the enclosure when the spectrometric apparatus is moved with the window facing the placement surface in the direction in which the spectrometric apparatus approaches or separates from the bottom section to restrict the position of the spectrometric apparatus in the plane perpendicular to the approaching/separating direction in such a way that the adhesive member overlaps with the area when viewed in the approaching/separating direction.
