    摘要: A projection apparatus includes: multiple scanning optical systems each including: a light source to emit a light beam; a scanner to deflect the light beam from the light source to form a scanning light beam; a magnifier including: at least one positive lens; and at least one negative lens, to magnify a scanning angle of the scanning light beam from the scanner; and a board having: a mounting surface; and a perpendicular line perpendicular to the mounting surface, the board mounting multiple scanners including the scanner of the multiple scanning optical systems on the mounting surface. Multiple scanning light beams have the scanning light beam from the scanner are arranged in rotational symmetry with respect to the perpendicular line with different angles in a plane of the mounting surface of the board, and the multiple scanning optical systems project the multiple scanning light beams to different regions from each other.

    摘要: An optical system including two imaging optical systems and two holders including one holder to hold one imaging optical system and other holder to hold the other one imaging optical system. Each holder includes a lens positioner to determine a position of a lens constituting each imaging optical system, and two contacts disposed apart from the lens positioner. When the one holder is combined with the other holder, the two contacts of the one holder contact the two contacts of the other holder with the lens maintained at the position determined by the lens positioner of each holder.

    摘要: A circuit includes a logic circuit containing a first transistor and a second transistor which are connected in series to each other between a high power supply and a low power supply in such a manner that an emitter of one of the first and second transistors is connected to a collector of the other of the first and second transistors. The first transistor is positioned closer to the high power supply, and the second transistor is positioned closer to the low power supply. The logic circuit operates in accordance with voltages input into bases of the first and second transistors. The circuit further includes a current amplifying circuit containing a third transistor whose collector is connected to one of the high and low power supplies, whose emitter is connected to the other of the high and low power supplies, and whose base is connected to an output from the logic circuit. The current amplifying circuit amplifies a current of a logic signal from the logic circuit and feeds, from the emitter of the third transistor, the current-amplified logic signal back to the base of the second transistor.
