Abstract: An operation support apparatus includes a display device (16) displaying a setting screen including an operating instruction information setting section in which operating instruction information related to the operating instruction is set and an applicable condition setting section having a menu for setting an applicable condition when notifying the operating instruction information. A CPU (11) selects one item from display items in the menu based on an operating input by a PD (14), and performs control to change and display display items in a lower menu below the menu depending on the selected item.

Abstract: Lengths of both sides of each end plane of a light-intensity distribution uniformizing element receiving a light flux and having an F-number of 1 are set to ½ of those of a reflecting surface of a reflecting optical-spatial modulator element, position information of uniformed light fluxes output from the light-intensity distribution uniformizing element is Fourier-transformed into diverging angle information indicated by incident light fluxes output from a first group of lenses, a relay deformed diaphragm intercepts an interference component of each incident light flux, which is expected to interfere with an outgoing light flux, to produce asymmetric light fluxes, the asymmetric light fluxes are incident on the reflecting optical-spatial modulator element, a projection lens deformed diaphragm removes stray light from outgoing light fluxes output from the reflecting optical-spatial modulator element, and an image is displayed according to the outgoing light fluxes.

Abstract: A digital mirror dence chip has a substrate, micro-mirrors disposed on the substrate, and a glass cover plate disposed over the micro-mirrors. Each micro-mirror is inclined by +10 degrees or −10 degrees with respect to the substrate to be set to an on-state or an off-state. Incident light produced in a lighting source system is totally reflected in a total internal reflection prism and is incident on the micro-mirrors through the glass cover plate. Outgoing light reflected by micro-minors in the on-state passes through a projection lens and is projected onto a screen to form an image on the screen. Also, outgoing light reflected by micro-mirrors in the off-state passes out of the projection lens. The glass cover plate is not parallel to the substrate. Therefore, light specularly reflected by a surface of the glass cover plate passes out of the projection lens.

Abstract: A DMD chip has a substrate, micro-mirrors disposed on the substrate, and a glass cover plate disposed over the micro-mirrors. Each micro-mirror is inclined by +10 degrees or −10 degrees with respect to the substrate to be set to an on-state or an off-state. Incident light produced in a lighting source system is totally reflected in a TIR prism and are incident on the micro-mirrors through the glass cover plate. Outgoing light reflected on micro-mirrors set to the on-state passes through a projection lens and are projected onto a screen to form an image on the screen. Also, outgoing light reflected on micro-mirrors set to the off-state passes out of the projection lens. The glass cover plate is inclined not to be parallel to the substrate. Therefore, light specularly reflected on a surface of the glass cover plate passes out of the projection lens.
