Abstract: PURPOSE:To provide the device which adopts a press part free from influences of imprinting of the background and the change of the luminance of an illuminaire by arranging a diffusion face in the face on the image forming means side of the press part. CONSTITUTION:A picture input device 1 which photographs an object consists of an object press part 2 which presses the fine object having physical data like a fingerprint, a photographing device 3 which photographs the object in the object press part 2, an illuminaire 4, a picture processing part 5, a monitor part 6, an information input part 7, and an output device 8. In this picture input device 1, the press part 2 is so constituted that the diffusion face is brought into contact with a transparent glass plate, and a diffusing irradiator is thereby obtained where the light from the illuminaire 4 is diffused to irradiate the epidermal ruggedness in the front end part of the finger. Thus, an influence of the change of the luminance of the illuminaire 4 is eliminated, and the object is photographed without an influence of the back-ground upon reflected light from the epidermal ruggedness in the front end part of the finger because the light from behind an object reception face is diffused to blur the background.

Title: Optical parts for uniformizing luminous flux
Inventor: OOISHI NORIJI
IPC: G02B5/00
Filed: 1989-06-20
Abstract: PURPOSE:To uniformize luminous fluxes with high efficiency without losing the beam characteristic of light by having plural parallel planes which are perpendicular to prism array forming surfaces and parallel with the ridge lines of prisms and are not zero in both reflectivity and transmittance between the specific two prism array forming surfaces. CONSTITUTION:The above optical parts have a pair of surfaces on which the prism arrays of a refractive index (n) having two kinds of the alternately repeating surfaces forming angles theta to -theta expressed by equations I, II with the normal of the surfaces are formed on the outer side and on which the prism arrays are parallel with each other as well. In the equations, delta is the smaller angle of either the spreading angle of the incident luminous flux or the spreading angle (+ or -delta) of the device utilizing the exit luminous flux and is delta<theta. The incident luminous flux perpendicular to the one prism array forming surface 20 to serve as an incident surface is divided by a prism to the luminous fluxes bent in the optical axis by the angles alpha, -alpha. These luminous fluxes repeat the branching by the transmission and reflection on a partial reflecting surface 7 and are thereby divided over a wide range. These luminous fluxes are again made into the original luminous fluxes by the other prism array forming surface 22 to serve as an exit surface, by which the many luminous fluxes dispersed over a wide range in parallel are obtd. The intensity of the nonuniform luminous fluxes is uniformized without impairing the beam characteristic thereof in this way. The uniform luminous flux is thus obtd. with the high efficiency.

Filed: 1980-11-07
Abstract: PURPOSE:To make it possible to restore a second control circuit automatically by imparting a voltage to a second output terminal with a first output voltage as a driving source when a short circuit is released. CONSTITUTION:When the second output terminal 42 of 43 is shorted, an input to a comparator amplifier 27 is decreased, the operation of control circuits 19 and 25 are stopped, and output transistors 15 and 21 are cut OFF. When the short circuit is released, the voltage of a first output terminal 41, which is generating the voltage regardless of the short circuit, is applied to the second output terminal 42 or 43 via a diode 33 or 35, the input voltage to the comparator amplifier 27 is increased, and the control circuits 19 and 25 are automatically restored. When the first output terminal 41 is shorted, a switch control circuit 38 becomes inoperative, and a switch circuit 37 is cut OFF. When the short circuit is released, the voltage is resupplied from the voltage source again. Thus  the protection of the short circuit of the output terminals can be performed by a simple circuit constitution.
