摘要： PROBLEM TO BE SOLVED: To precisely discriminate the counterfeit for even paper sheets deteriorated in a reflecting characteristic or absorbing characteristic because of soil, etc., by allowing a counterfeit discriminating means to discriminate the counterfeit for paper sheets to be checked through the use of correction data. SOLUTION: An irradiating means (mercury lamp) 14 radiates light with wavelength components in a specific wavelength band and that in another wavelength bad onto the paper sheets to be checked C. A photodetector part A receives the light reflecting the irradiating light from the radiating means on the paper sheet to be checked C and respectively detects light quantities in the specific wavelength band and other wavelength band concerning this reflected light. Obtained light quantity data is given to an arithmetic means (differential amplifier) 23 to correct light quantity data in the specific wavelength band by using light quantity data in other wavelength band. Correction data obtained by the arithmetic means 23 is given to the counterfeit discriminating means B to discriminate the counterfeit the paper sheets to be checked C based on this correction data.

摘要： PROBLEM TO BE SOLVED: To provide a pulse motor for a camera drive unit capable of stably stopping a permanent magnet rotor at every step by arranging the rotor so as to be held with two iron core members, simple in constitution and low in cost. SOLUTION: The rotor 7 is magnetized at four poles and arranged to be held with two iron core members around which coils are wound to be rotated with the step of 45 deg.. A magnetic material member 11 has a nearly semicircular- arc shape and three projections 11A are formed at intervals of 90 deg.. Further, each projection 11a is arranged to be positioned at the upper part between the adjacent magnetic poles of the rotor 7 at four stable stopping positions of the rotor 7. Consequently, eight stable stopping positions are obtained.

摘要： PROBLEM TO BE SOLVED: To provide a focal-plane shutter for a camera provided with a simply constituted setting mechanism capable of surely setting a preceding blade driving member and a following blade driving member in charging positions. SOLUTION: When a member attached to a camera body side (not shown by the figure) moves the set part 2d of the preceding blade driving member 2 to the right, linked with the taking up of a film, the push-moving part 2e of the preceding blade driving member 2 pushes the push-moved part 3d of the following blade driving member 3, at the same time when the preceding blade driving member 2 is turned counterclockwise, so that the following blade driving member 3 is turned counterclockwise as well. After that, iron pieces 4 and 5 are stopped at contact positions with the iron cores 14 and 15 of the electromagnet. This state is kept by the member on the camera body side until the shutter is released.

摘要： PROBLEM TO BE SOLVED: To provide a focal-plane shutter capable of preventing a coupling shaft from colliding with an opening end face for forming an aperture when a blade group travels without specially working a shutter bottom board and a cover plate constituting the blade group by rotatably coupling plural blades with plural arms through the coupling shafts. SOLUTION: This focal-plane shutter is provided with the blade groups 7 to 11 which are rotatably coupled with plural arms 5 and 6 pivotally attached to the bottom board 1 through the coupling shafts 12 to 21. The blade groups 7 to 11 are constituted to travel between a developing position where the apertures 1a and 2a are covered and a superposing position where the apertures 1a and 2a are opened. In such a case, projected parts 5a and 6a projected more than the maximum projected height of the coupling shafts 12 to 21 are formed on the arms 5 and 6.

摘要： PROBLEM TO BE SOLVED: To correct the phase error of an electric signal caused by the dispersion/ convergence of the luminous flux emitted from a light source. SOLUTION: An optical encoder comprises an optical system, wherein a light source 1, a displaceable moving slit plate 2, a fixed slit plate 3 and photodetectors 4A and 4B are arranged along an optical axis O. The moving slit plate 2 has a slit line C having a specified period, which is aligned in the displacement direction so as to cross the optical axis O. The fixed slit plate 3 has slit lines A and B having the specified period, which are arranged in the displacement direction and have the mutually shifted space phases. The light source 1 irradiates the luminous flux on the slit line C of the moving slit plate 2 along the optical axis O. The photodetectors 4A and 4B separately receive the luminous flux through the respective slit lines A and B of the fixed slit plate 3 and output a pair of the electric signals having the period in correspondence with the displacement amount of the moving slit plate 2 and the relative phase relationship in correspondence with the displacement direction. A toric lens 5 is inserted so as to be across the optical axis O of the light source 1 and rotatably held around the optical axis O. The error, which appears in the relative phase relationship of a pair of the electric signals, can be adjusted in this way.

摘要： PROBLEM TO BE SOLVED: To correct the phase error appearing in the output of an optical encoder optically. SOLUTION: A moving slit plate 2 has a slit line 20 having a specified period P, which is aligned so as to cross optical axes OA and OB. A fixed slit plate 3 has slit lines 30A and 30B having the specified period P, whose space phases are mutually shifted by P/4 in correspondence with respective light sources 1A and 1B. The light sources 1A and 1B irradiate luminous fluxes LA and LB on the slit line 20 of the moving slit 2 along the optical axes OA and OB, respectively. Photodetectors 4A and 4B separately receive the luminous fluxes through the respective slit lines 30A and 30B of the fixed slit plate 3 and output two electric signals having the relative phase relationship in correspondence with the period corresponding to the displacement amount and displacement direction of the moving slit 2. A wedge-shaped prism 5 is inserted so as to be across the optical axis OB of one light source 1B and held rotatably around the optical axis OB. The error, which appears in the relative phase relationship of two electric signals, can be adjusted in this way.

摘要： PROBLEM TO BE SOLVED: To stably obtain the closing time of two contacts. SOLUTION: The armature 2a of an armature member 2 is fixed on the base part 1g of a shutter bottom board 1, and biases a free end 2a1 by its own elasticity so as to abut on the regulation part 1h of the board 1. The tip of the armature 12f obtained by bending the mount plate 12 of an electromagnet is fit in the hole 11 of the board 1. The terminal 2b of the member 2 pierces a hole 13d and is soldered on a printed wiring board 13. The terminal 12g obtained by bending the mount plate 12 pierces a hole 13e and is soldered on the wiring board 13. Just before a front blade group is totally opened, the pressing part 3d of a front blade driving member 3 presses the armature 2a against biasing force and brings it into contact with the armature 12f.

摘要： PROBLEM TO BE SOLVED: To integrally mold a base plate part and an upper plate part of synthetic resin so that they may be nearly in parallel and to easily attach the rotary shaft of a turning member between both of them. SOLUTION: The upper plate part 1c is nearly in parallel with the base plate part 1b of a shutter base plate 1, and integrally molded with the base plate part 1b of the synthetic resin through supporting wall parts 1d, 1e, 1f and 1g. Two bearing holes 1r whose left side is partially opened are formed on the upper plate part 1c. Two bearing holes 1s having nearly the same shape are formed on the base plate part 1b so that a bearing position may be aligned with the bearing hole 1r. A front blade driving member and a rear blade driving member are attached by pressing the shafts integrally provided in the bearing holes 1r and 1s.
