Abstract: An image display apparatus includes: a transparent board that transmits visible light; a screen that is provided on one surface of the transparent board; a projector that projects an image toward the screen from the other surface side of the transparent board; and a support unit that supports the transparent board from the other surface side. The projector is disposed outside of the space that is enclosed by the transparent board and the support unit.

Abstract: The objective of the present invention is to provide a lens cover for a projector that prevents the entry of projection light into the user's field of view. This lens cover for a projector has: a first surface that faces a projection lens and into which projection light from the projection lens is irradiated; a second surface that emits the projection light that was irradiated into the first surface; and a refracting part that is provided on the first surface or the second surface or on both surfaces; that is made up of a plurality of recessed parts, and that refracts the projection light in one direction. The lens cover is formed from a material having transparency.

Abstract: The object of the present invention is to provide a terminal panel whose surface is unlikely to be scratched and which makes scuff marks inconspicuous. A terminal panel of the present invention includes: at least, one terminal into which a connector is inserted from the outside; and, a metal plate with the terminal attached thereto, having a plurality of recesses (7) formed on its surface.

Abstract: One object of the present invention is to prevent part of outgoing light emitted from a light emitter from reflecting in a specific direction, while blocking out part of the outgoing light, in a light source apparatus. The light source apparatus is provided with a light emitter that emits light; a reflector that reflects outgoing light emitted from the light emitter in a specific direction; and a light shield made from metal and disposed on a lateral side or at the back of the reflector. A plurality of concave portions or convex portions are formed at least in a partial area of the light shield.

Abstract: The present invention realizes an interactive unit attachment structure that enables a projector to have an electronic pen function regardless of the type of projection surface. The attachment structure of the interactive unit, which is provided with a first sensor and a second sensor and which is attached to a wall hanging unit that suspends the projector from the wall such that the interactive unit can slide in a direction projecting from the wall, includes a slot in a slot provided in the wall hanging unit that extends in the direction of sliding and first and second protrusions provided in the interactive unit that protrude into the slot.

Abstract: A frame housing is provided on a peripheral surface of a display unit. The frame housing includes: a plurality of divided frames including a plurality of attachment portions including a through hole used for screw-fastening to a screw hole provided in the peripheral surface of the display unit. The through hole is an oblong hole with a long-axis direction of the oblong hole arranged in a direction along the peripheral surface of the display unit.

Abstract: An image pick-up device includes an image pick-up unit 3 for shooting a subject 2 in a desired direction, a light source unit composed of a circular type cold-cathode tube 4 fixed to a predetermined portion of the image pick-up unit 3 in such a way that an illuminating direction of the light source unit 3 is substantially coincident with a shooting direction of the image pick-up unit 4 and a support light source unit 5 housed in an arm 6 for supporting the image pick-up unit 3. The subject 2 to be shot by the image pickup unit 3 is always illuminated with light from the circular type cold-cathode tube 4.
