Show.

  The rotating shaft 15b of the movable mirror 15 is supported by the rear frame 50 of the optical case 3 so as to be rotatable. In addition, a reverse spring 52 (biasing means) for biasing the movable mirror 15 to keep the state shown in FIG. 7 (a state functioning as an electronic camera) is provided at the upper end of the rotating shaft 15b.

  A guide groove 54 extending in the sliding direction is formed on the upper surface 5 a of the light source case 5, and a lower end portion of the rotating shaft 15 b is inserted into the guide groove 54 via a rotation lever 56. The rotating lever 56 can be rotated in the guide groove 54 together with the rotating shaft 15b in a state where the lower end portion of the rotating shaft 15b is attached. The rotation lever 56 is slidable in the guide groove 54 in accordance with the slide operation of the optical case 3 while being inserted in the guide groove 54.

As shown in FIGS. 7 and 8, the rotary lever 56 includes a base end portion 56a and a lever portion 56b extending radially outward from the base end portion 56a. The lever portion 56 b moves (rotates) along the upper surface 5 a of the light source case 5.

The relationship between the rotating lever 56 and the protrusion 58 will be described.
In a state of functioning as an electronic camera (a state where the slide operation is not performed; see FIG. 7), the movable mirror 15 is urged counterclockwise in FIG. 7 by the urging force of the reverse spring 52. At this time, the lower end portion of the rotation shaft 15b is located at the rear end portion of the guide groove 54, and the position of the rotation shaft 15b in the front-rear direction is restricted. Further, the protrusion 58 contacts the lever portion 56 b at a position where the incident light 20 a is projected onto the light receiving surface 9 a of the imaging unit 9. That is, the angle of the movable mirror 15 is regulated by the position of the rotating shaft 15b in the front-rear direction and the position of the protrusion 58.

  On the other hand, when the optical case 3 is slid, the lever portion 56b keeps the contact with the protrusion 58 and keeps the rotating shaft 15b clockwise in FIG. Rotate. At this time, the lower end portion of the rotation shaft 15b moves from the rear end portion of the guide groove 54 toward the front (toward the throwing and combining lens 7).

  In a state of functioning as a projector (sliding state; see FIG. 8), the lower end portion of the rotation shaft 15b moves to the front end portion of the guide groove 54, and the position of the rotation shaft 15b in the front-rear direction is restricted. Further, the lever portion 56b further rotates clockwise while maintaining the state of being in contact with the protrusion 58 against the urging force of the reverse spring 52, and the movable mirror 15 is projected light 22a projected from the light source portion 11. It will be rotated and retracted to a position where it will not be blocked.

The resolution can be increased with this configuration.

  Further, since the micromirror device of the projection device 13 can be moved by ON / OFF control at an angle of about 10 degrees, when the imaging unit 9 and the light source unit 11 are provided within this angle, the layout inside the device is restricted. However, the degree of freedom of this layout can be expanded by not passing through the projection device 13 during imaging.
