摘要： A paper sheet fluorescence sensor utilizes an ultraviolet-reflecting filter to orthogonally irradiate a conveying path with ultraviolet light and receive fluorescence from a paper sheet. The ultraviolet-reflecting filter reflects ultraviolet light emitted from an ultraviolet light source, to produce light having an optical axis orthogonal to the conveying path of the paper sheet. The light transmitted through the ultraviolet-reflecting filter is detected by a fluorescence detecting device. An ultraviolet-transmitting filter is disposed between the ultraviolet-reflecting filter and the ultraviolet light source, so that the light reflected by the ultraviolet-reflecting filter attains a higher ultraviolet content, thereby improving light-detection accuracy.

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.
