In conjunction with this, the LED unit 131 moves to an arrow D in FIG. 5A which is a diffusion irradiation position (non-projection position) for emitting light toward the diffusion irradiation optical system 160.
The optical image to be imaged passes through the camera imaging optical system 150, passes through the liquid crystal panel unit 132, and forms an image on the light receiving surface of the camera unit 140. The imaged light image is converted into an electrical signal by the camera unit 140 to generate image data. Image data generated by the camera unit 140 is stored in a data storage unit such as the internal memory 112.

FIG. 6 is an explanatory diagram when the camera function is used in the mobile phone 100 according to the third embodiment (hereinafter referred to as “Embodiment 3”) of the present invention. FIG. 7 is an explanatory diagram when using the projection function in the mobile phone 100 according to the third embodiment.
Here, FIG. 6A and FIG. 7A are explanatory diagrams viewed from the back of the mobile phone 100. FIG. 6B and FIG. 7B respectively show a liquid crystal panel support member 191 as a spatial light modulator support member that also functions as a camera support member inside the mobile phone, and an LED support member 192 as a light source support member. It is explanatory drawing of the internal structure which looked at the vertical cross section containing each rotation axis of this from the right direction of Fig.1 (a) and Fig.2 (a). FIG. 6C and FIG. 7C are explanatory diagrams of the liquid crystal panel support member 191 that supports the liquid crystal panel unit 132. FIGS. 6D and 7D are explanatory diagrams of the LED support member 192 that supports the LED portion 131.

  In FIG. 6B and FIG. 7B, illustration of the rotation shaft 191c of the liquid crystal panel support member 191 and the rotation shaft 192c of the LED support member 192 is omitted for simplification of illustration. The description of the configuration and operation common to the mobile phone 100 of the first embodiment is omitted.

In the first embodiment described above, the light generation unit 130 is configured such that the liquid crystal panel unit 132 and the LED unit 131 are interlocked with each other facing each other. It is configured to move with. In such a configuration, when the camera and the illumination lamp function are used, the liquid crystal panel unit 132 is controlled to maximize the light transmittance. This is because the liquid crystal panel unit 132 is located between the LED unit 131 and the diffusion irradiation optical system 160, and it is necessary to allow as much light as possible to pass through the liquid crystal panel unit 132. This is because the function of modulating light is not required.
In the second embodiment, the liquid crystal panel unit 132 is fixed at a position facing the camera imaging optical system 150. When the camera function is used, the camera unit 140 faces the liquid crystal panel unit 132, and the projection function When using the LED 131, the LED 131 faces the liquid crystal panel 132. In such a configuration, when the functions of the camera and the illumination lamp are used, the liquid crystal panel unit 132 is controlled so as to maximize the light transmittance. This is because the liquid crystal panel unit 132 is positioned between the camera imaging optical system 150 and the camera unit 140, so that as much light as possible can pass through the liquid crystal panel unit 132. This is because it does not require a function of modulating the light.
As in the first and second embodiments described above, the liquid crystal panel unit 132 moves together with the LED unit 131 in a state of facing the LED unit 131, and the liquid crystal panel unit 132 is fixed to the camera imaging optical system 150. In any case, when using the camera function, the light passes through the liquid crystal panel unit 132 even though the function of modulating the light of the liquid crystal panel unit 132 is not required. Since the liquid crystal panel unit 132 gradually deteriorates as light passes therethrough, continuing to transmit light in a state that does not require the function of modulating light causes the liquid crystal panel unit 132 to be deteriorated uselessly. become.

Therefore, in the third embodiment, when the camera function that does not use the function of modulating the light of the liquid crystal panel unit 132 is used, the following configuration that does not transmit the light to the liquid crystal panel unit 132 is adopted. That is, in Embodiment 3, a liquid crystal panel support, which is a revolver-type support member, is used as a spatial light modulation unit support member formed of a disk-shaped rotating body having a rotation shaft 191c that is rotatably supported by the main body of the mobile phone 100. A member 191 is provided. The liquid crystal panel support member 191 is provided with the liquid crystal panel portions 132 at different passing positions of the rotating body that can pass through the position facing the camera imaging optical system 150 and the position facing the diffusion irradiation optical system 160. In addition, an illumination opening for allowing illumination light from the LED unit 131 to pass therethrough is formed.
Further, as shown in FIGS. 6A and 6B and FIGS. 7A and 7B, a part of the outer peripheral portion of the liquid crystal panel support member 191 is exposed to the outside from the opening on the top surface of the main body of the mobile phone 100. It is exposed to protrude. The exposed portion of the liquid crystal panel support member 191 is a liquid crystal panel operation unit 181 for operating the liquid crystal panel support member 191 to rotate. Furthermore, an LED support member 192 is provided adjacent to the front side of the liquid crystal panel operation unit 181 (the side where the image display unit 119 is formed). A part of the outer periphery of the LED support member 192 is exposed to the outside from the opening on the top surface of the main body of the mobile phone 100. The exposed portion of the LED support member 192 is an LED operation unit 182 for operating the LED support member 192 to rotate. Also, as shown in FIGS. 6C and 7C, the liquid crystal panel support member 191 has a liquid crystal panel part 132 and a camera part 140 attached at predetermined locations, and when the illumination lamp function is used. An illumination opening 191a through which the light from the LED portion 131 passes is formed.

  When the mobile phone 100 according to the third embodiment uses the camera function and the illumination lamp function, the liquid crystal panel support member is operated so that the liquid crystal panel operation unit 181 is operated so that the liquid crystal panel unit 132 and the camera unit 140 are in the light incident position. 191 is rotated. That is, the camera unit 140 is moved to the light incident position indicated by the arrow I in FIG. 6B that receives the light image from the camera imaging optical system 150, and the liquid crystal panel unit 132 is moved to the camera imaging optical system 150. And the diffusion irradiation optical system 160 are moved to an incident retraction position indicated by an arrow H in FIG. Further, the LED operation unit 182 is operated together with the liquid crystal panel operation unit 181, and the LED support member 192 is rotated so that the LED unit 131 is in the position for diffusion irradiation. That is, the LED unit 131 that was in the non-projection position is moved to the diffusion irradiation position indicated by the arrow G in FIG. 6B where light is irradiated toward the diffusion irradiation optical system 160. Since the LED 131 at the diffusion irradiation position faces the diffusion irradiation optical system 160 through the illumination opening 191a, the illumination lamp function can be used.

  On the other hand, when the image projection function is used in the mobile phone 100 of the third embodiment, the liquid crystal panel operation unit 181 is operated to rotate the liquid crystal panel support member 191 from the state of FIG. Accordingly, the liquid crystal panel unit 132 is replaced with the camera unit 140 and moved to the projection position indicated by the arrow I in FIG. Further, the camera unit 140 is moved to the retracted position indicated by the arrow H retracted from the light incident position indicated by the arrow I in FIG. Further, the LED operation unit 182 is operated together with the operation of the liquid crystal panel operation unit 181 to rotate the LED support member 192 by 90 ° in the arrow α direction. Thereby, the LED part 131 faces the liquid crystal panel part 132, and becomes a projection position indicated by an arrow I in FIG.

  The configuration in which the liquid crystal panel support member 191 is rotated by 180 ° and the LED support member 192 is rotated by 90 ° among the two support members adjacent to each other is not suitable for the LED support member 192 to have a 90 ° rotation range. This can be realized by providing the illustrated stopper and providing the liquid crystal panel support member 191 with a not-illustrated stopper so that the rotation range is 180 °. Further, the present invention is not limited to this configuration, and the liquid crystal panel operation unit 181 and the LED operation unit 182 are each rotationally driven from one common operation unit via gears having different reduction ratios, and the LED support member is in contact with the liquid crystal panel support member 191. A configuration may be provided in which a rotation angle of 192 is halved.

  In the third embodiment, the liquid crystal panel support member is also used as the camera support member by providing the camera unit 140 on the liquid crystal panel support member 191 as the spatial light modulation unit support member. The spatial modulation support member is not limited to this, and only the liquid crystal panel unit 132 may be attached without attaching the camera unit 140 to the liquid crystal panel support member 191. In this case, the camera unit 140 is provided on the LED support member 192, and the LED support member 192 is also used as the camera support member. In this configuration, the liquid crystal panel support member 191 is provided with a camera opening so that light incident through the camera imaging optical system 150 is incident on the camera unit 140 when the camera function is used.

  As described above, according to the third embodiment, the liquid crystal panel unit 132 is provided on the liquid crystal panel support member 191, and can be rotated and moved without moving together with the camera imaging optical system 150 and the LED unit 131 facing each other. It is. Accordingly, when the camera function that does not use the function of modulating the light of the liquid crystal panel unit 132 is used, the liquid crystal panel unit 132 is not opposed to either the camera imaging optical system 150 or the diffusion irradiation optical system 160. FIG. It can be moved to the retracted position indicated by the arrow H in (b). At the retracted position indicated by the arrow H, when the camera function that does not require the function of modulating the light of the liquid crystal panel unit 132 is used, the light is not incident on the liquid crystal panel unit 132, and the liquid crystal panel unit 132 is exposed to light. Unnecessary deterioration can be suppressed.

In the first to third embodiments, the camera imaging optical system 150 and the diffusion irradiation optical system 160 are fixed to the main body of the mobile phone 100, and the camera unit 140, the LED unit 131, and the liquid crystal for these optical systems 150 and 160 are fixed. By changing the positional relationship with the panel unit 132, the camera function and the image projection function are switched. Table 1 summarizes the positional relationship of the above-described members when using the camera function and the image projecting function of the first to third embodiments. In Table 1, a position facing the camera imaging optical system 150 is L, a position facing the diffusion irradiation optical system 160 is F, and a position not facing either is x. From Table 1, it can be seen that the difference in the positional relationship of each member in Embodiments 1 to 3 is that the position of the liquid crystal panel unit 132 is different when the camera function is used.

Thus, the optical system support member 193 is rotated. That is, the camera imaging optical system 150 receives the light incident as indicated by an arrow J in FIG. 8B in which the optical image of the imaging target that has passed through the camera imaging optical system 150 forms an image on the light receiving surface of the camera unit 140. Move it to the working position. Accordingly, the diffusion irradiation optical system 160 diffuses the light emitted from the light generation unit 130 including the LED unit 131 and the liquid crystal panel unit 132 and uniformly irradiates the external irradiation surface in FIG. 8B.
