Abstract: A display device includes a first light source for emitting first light in blue, a second light source for emitting second light, and a color filter. The filter has a translucent sheet, a first printed area part for passing the first light to provide a first display excluding an overlapped portion of the first display and a second display and preventing the second light from passing therethrough, a second printed area part for passing the second light to provide the second display excluding the overlapped portion and preventing the first light from passing therethrough, a third printed area part for dimming and passing the first and second lights to provide the overlapped portion, a background printed area part for preventing the first and second lights from passing therethrough, and a white light converting part for the first light passing therethrough into white light.

Abstract: An operator distinguishing device has a display part, an operation part provided in a touch panel arranged in front of the display part, and a control part. The touch panel has a plurality of electrodes for generating electrostatic capacity change when a hand of one of the operators approaches the touch panel, and the touch panel is arranged at a position where the touch-panel side hands of the operators need to approach to the touch panel from lateral side edge portions, which are at operator-to-operate sides, of the touch panel, respectively. The control part detects the electrostatic capacity change level generated by an approaching hand of the operator to distinguish the operator, who approaches the hand to the touch panel, from the other operator before the hand touches the touch panel.

Abstract: A pair of hold pieces 19, which elastically hold the two side edges 25 of an elastic securing member 21 for mounting a cover member 12 onto a housing 11 to thereby be able to position the shifting inclination position of the elastic securing member 21 provisionally at an arbitrary position, are disposed in either of the housing 11 or cover member 12 which supports the elastic securing member 21.
