Abstract

An electronic apparatus includes a light source; a casing that accommodates the light source and includes a first window transmitting light from the light source; a water inhibitor that is formed from a circumferential wall and a window seal in a monoblock form, the circumferential wall being disposed along a inner circumference of the casing and preventing invasion of water from the circumference of the casing into the casing, the window seal being disposed inside the first window and preventing invasion of water from the first window into the casing, the water inhibitor preventing invasion of water into the casing and transmitting the light from the first window to a outside of the casing; and a light guide member that is disposed over the first window and guides the light transmitted through the first window.

Claims (20)

1. An electronic apparatus comprising:

a light source;

a casing that accommodates the light source and includes a first window configured to pass light derived from the light source and a second window;

a water inhibitor that is formed from a circumferential wall and a window seal in a monoblock form, the circumferential wall being disposed along an inner circumference of the casing and inhibiting invasion of water from the circumference of the casing into the casing, the window seal being disposed inside the first window such that the window seal substantially covers the first window, the window seal inhibiting invasion of water from the first window into the casing while allowing the light from the first window to pass outside of the casing; and

a light guide member that is disposed over the first window and guides the light passing through the first window, wherein an outer part of the casing includes a groove configured to accommodate the light guide member; and the second window is configured to pass the light, wherein the light guide member connects the first window and the second window and at least part of the light guide member between the first window and the second window passes the light.

2. The electronic apparatus according to claim 1 , wherein,

the casing includes a cover member made of light transmissive material and covering the light guide member,

wherein the cover member includes an illumination window through which the light guided in the light guide member passes.

3. The electronic apparatus according to claim 1 , further comprising:

a light shield member for blocking the light provided on part of the circumference of the light guide member.

4. The electronic apparatus according to claim 1 , further comprising:

protrusions and depressions provided on at least part of an incident surface of the light guide member, the light passing through the first window incident to the incident surface.

5. The electronic apparatus according to claim 1 , wherein,

a depression is provided in at least one of the window seal and the light guide member, and

a space is interposed between the light guide member and the window seal.

6. An electronic apparatus comprising:

a light source;

a casing that surrounds the light source and has a first window configured to pass light derived from the light source and a second window;

a water inhibitor that includes a circumferential wall disposed along the inner circumference of the casing and a window sealing part that is disposed inside the first window such that the window sealing part substantially covers the first window, the water inhibitor being configured to inhibit invasion of water into the casing and allow light to pass through the first window and the window sealing part, the water inhibitor being formed from the circumferential wall and the window sealing part in a monoblock form; and

a light guiding member that is disposed on an outer part of the casing and guides the light from the first window, wherein an outer part of the casing includes a groove configured to accommodate the light guiding member: and the second window is configured to pass the light, wherein the light guiding member connects the first window and the second window and at least part of the light guiding member between the first window and the second window passes the light.
