<Example of Configuration of Camera Device 200 According to First Embodiment>
Next, a configuration example of the camera device 200 according to the present embodiment will be described with reference to FIG. FIG. 3A is a cross-sectional view illustrating a configuration example of the camera device 200 when the viewfinder is stored. FIG. 3B is a cross-sectional view illustrating a configuration example of the camera device 200 when the viewfinder is used. Hereinafter, a case where the camera apparatus 200 includes only the photographing lens 203 among the photographing lenses 201 and 203 will be described as an example.

  As illustrated in FIG. 3, the camera device 200 includes a photographing lens 203, an image sensor 204, a liquid crystal panel 102, and a viewfinder unit 205. Note that the housing 101 of the wireless communication terminal 100 corresponds to a main body (camera main body) of the camera device 200.

A conversion result (image) by the image sensor 204 is displayed on the liquid crystal panel 102 or the liquid crystal panel 208.

  For example, when the finder is stored (FIG. 3A), an image is displayed on the liquid crystal panel 102 disposed on the front surface of the casing 101 of the wireless communication terminal 100, and no image is displayed on the finder liquid crystal panel 208. . On the other hand, when the finder is used (FIG. 3B), an image is displayed on the finder liquid crystal panel 208, and no image is displayed on the liquid crystal panel 102. Thereby, an increase in power consumption is suppressed. Note that an image may be displayed on both the liquid crystal panels 102 and 208 when the viewfinder is used (FIG. 3B).

(Finder unit 205)
The finder housing 206 has a prismatic shape, for example, and is fixed inside the housing 101. The finder housing 206 has a space area that can accommodate all or some of the plurality of components provided in the finder housing 207.

  The finder housing 207 has a prismatic shape, for example, and is slidable with respect to the finder housing 206. In the example of FIG. 3, the finder casing 207 is provided so that the sliding direction is the horizontal direction of the casing 101 (the vertical direction of the paper). That is, the finder unit 205 is provided so that it can be expanded and contracted in the lateral direction of the casing 101 (vertical direction of the paper surface).

  For example, when the finder is stored (FIG. 3A), the finder casing 207 is slid and stored inside the casing 101. In other words, the finder unit 205 is shortened and stored in the housing 101. On the other hand, when the finder is used (FIG. 3B), the finder housing 207 slides out to the outside of the housing 101. In other words, the finder unit 205 extends and extends outside the housing 101. The finder unit 205 includes, for example, an elastic body (not shown) such as a spring that urges the finder housing 207 in the extending direction, and the finder housing 207 urged by the elastic body at a predetermined extension position. Alternatively, a stopper (not shown) that is fixed to the storage position is provided.

  The finder housing 206 is provided with a liquid crystal panel 208. More specifically, the liquid crystal panel 208 is provided near the bottom surface of the finder housing 206 (the lower surface of the paper; the surface closer to the inside of the housing 101). The liquid crystal panel 208 is provided so that its display surface faces the extension direction of the finder unit 205 (upward on the paper surface).

  The finder housing 207 is provided with an objective lens 209, an eyepiece lens 210, a mirror 211, a finder window 212, and a rotation shaft 213.

  The objective lens 209 is provided near the bottom surface of the finder housing 207 (the lower surface of the paper; the surface closer to the inside of the housing 101). The objective lens 209 is provided so that its optical axis faces the direction of expansion and contraction of the finder unit 205 (the vertical direction of the paper). That is, the objective lens 209 is provided so that its optical axis is perpendicular to the display surface of the liquid crystal panel 208.

  The mirror 211 is provided on the exit side of the objective lens 209. A rotating shaft 213 is provided at the lower end of the mirror 211.

  For example, when the viewfinder is housed (FIG. 3A), the mirror 211 rotates about the rotation axis 213 in a direction (the left side of the drawing) in which the reflection surface is substantially parallel to the optical axis of the objective lens 209. To do. As a result, a space area for accommodating the eyepiece lens 210 and the finder window 212 is formed on the reflection surface side of the mirror 211. On the other hand, when the viewfinder is used (FIG. 3B), the mirror 211 has the optical axis of the objective lens 209 reflected by the mirror 211 and the optical axis of the eyepiece lens 210 approximately coincident with the rotation axis 213 as a fulcrum. Rotate to the position (initial position) to be performed (to the right of the page). In the example of FIG. 3, the mirror 211 rotates about the rotation axis 213 to a position where the reflection surface forms an angle of about 135 degrees with respect to the optical axis of the objective lens 209. Thereby, the mirror 211 can reflect the light that has passed through the objective lens 209 toward the eyepiece lens 210.

  The eyepiece 210 is provided in the vicinity of the side surface of the finder housing 207 (the right surface of the paper; the front surface side of the housing 101). The eyepiece 210 is provided so that its optical axis is in a direction different from the direction of expansion and contraction of the finder unit 205. In the example of FIG. 3, the eyepiece 210 is provided so that its optical axis faces the thickness direction of the housing 101 (the horizontal direction of the paper). That is, the optical axis of the eyepiece lens 210 and the optical axis of the objective lens 209 are in a state of intersecting at a right angle. Further, the eyepiece 210 is provided so as to be movable along its optical axis.

  The finder window 212 is provided outside the finder housing 207 with respect to the eyepiece lens 210. Further, the finder window 212 is provided so as to be movable together with the eyepiece lens 210.

  For example, when the finder is housed (FIG. 3A), the eyepiece 210 and the finder window 212 move in the direction of the finder housing 207 (to the left in the drawing) along the optical axis. Along with this, the mirror 211 rotates so as to form a spatial region on the reflecting surface side. The eyepiece 210 and the finder window 212 are housed in a spatial region provided on the reflection surface side of the mirror 211. That is, when the finder is housed (FIG. 3A), the objective lens 209, the eyepiece 210, the mirror 211, and the finder window 212 are all housed in the finder housing 207.

  On the other hand, when the finder is used (FIG. 3B), the eyepiece 210 and the finder window 212 move along the optical axis in the direction outside the finder housing 207 (to the right of the page) (accordingly, the mirror) 211 is turned to the initial position, and the light that has passed through the objective lens 209 can be reflected toward the eyepiece lens 210). Thereby, at least the finder window 212 protrudes outside the finder housing 207 (finder main body). As a result, it is possible to secure a necessary optical path length from the display surface of the liquid crystal panel 208 to the finder window 212 through the objective lens 209, the mirror 211, and the eyepiece lens 210. This is particularly effective in recent years when the thickness of the wireless communication terminal 100 is reduced. The finder unit 205 includes, for example, an elastic body (not shown) such as a spring that urges the eyepiece lens 210 and the finder window 212 toward the outside of the finder housing 207, and an eyepiece urged by the elastic body. A stopper (not shown) for fixing the 210 and the finder window 212 to a predetermined overhanging position is provided.

  The guide 214 is provided at, for example, the lower end portion of the finder window 212 or in the vicinity thereof. Here, when the finder unit 205 is stored, the finder unit 205 is shortened and stored in the housing 101 by pressing the expanded finder unit 205 in the shortening direction (downward on the paper surface). At this time, the guide 214 uses the finder window 212 (and the eyepiece lens 210) projecting from the finder housing 207 in the direction toward the inside of the finder housing 207 (paper surface). To the left). As a result, the finder window 212 protruding from the finder housing 207 is housed inside the finder housing 207 by simply pressing the extended viewfinder 205 in the shortening direction, and the finder housing 207 slides into the housing. It is stored inside the body 101. Note that the guide 214 may be provided anywhere in the finder unit 205 as long as the function similar to the above can be realized.

  In short, when the finder is housed (FIG. 3A), the objective lens 209, the eyepiece 210, the mirror 211, and the finder window 212 are all housed in the finder housing 207, and the finder housing 207 is inside the housing 101. It is stored in. Thereby, the scale of the finder unit 205 is reduced. Thereby, the scale of the camera device 200 and the wireless communication terminal 100 including the camera device 200 is also reduced.

  On the other hand, when the finder is used (FIG. 3B), the finder unit 205 extends and extends to the outside of the housing 101. Then, the finder window 212 (and the eyepiece 210) moves in a direction (perpendicular direction) different from the extending direction of the finder unit 205 and projects from the finder housing 207. Accordingly, it is possible to secure a necessary optical path length from the display surface of the liquid crystal panel 208 to the finder window 212 through the objective lens 209, the mirror 211, and the eyepiece lens 210.

  When the viewfinder is used (FIG. 3B), the objective lens 209 collects the luminous flux of the image displayed on the liquid crystal panel 208 and creates a real image at the focal point. This real image is reflected by the mirror 211 to the eyepiece lens 210. The eyepiece 210 enlarges a real image created by the objective lens 209 and reflected by the mirror 211. A real image (image) magnified by the eyepiece lens 210 can be confirmed by looking into the viewfinder window 212.

  As described above, in the camera device 200 according to the present embodiment, the eyepiece 210 is configured to be movable in a direction different from the expansion / contraction direction of the finder body. Thereby, since the camera apparatus 200 according to the present embodiment can store the eyepiece 210 in the finder main body when the finder is stored, the scale can be reduced. Furthermore, since the camera device 200 according to the present embodiment can project the eyepiece 210 from the finder body when using the finder, it is possible to ensure a necessary optical path length.

  In addition, since the camera device 200 according to the present embodiment can completely store the finder window 212 (eyepiece portion) inside the housing 101 when the finder is stored, the finder window 212 can be prevented from being soiled. , Can improve the design. Note that the liquid crystal panel 102 can be disposed in almost the entire area of the front surface of the housing 101 without being affected by the finder unit 205.
