摘要： PROBLEM TO BE SOLVED: To provide a small-sized device by forming reflected lights of two parts irradiated by each light source to divide optical-paths into and image-form at each image-formation lens and superimposing by an optical device to output image signals superimposed from an image device.
SOLUTION: A semiconductor-chip part 2 attracted on an end of a nozzle 4 is carried on a circuit board 3 and a box 5 is taken out and put in between the chip 2 and the circuit board 3. A plurality of LED light sources 8, 9 are placed surroundings the windows 6, 7 on the box 5 to irradiate the chip 2 and the circuit board 3 respectively. The reflected lights by the chip part 2 and the circuit board 3 are totally-reflected respectively at a surface and a backside of a total reflection mirror faces of optical path dividing mirror 10 to form optical paths L1, L2. Image-formation lenses 12 are placed respectively on the optical paths L1, L2 to form images of the chip 2 and the circuit board 3, and then both of the images are led into an optical-path mirror 11. Thereby, position shift between both parts can be easily recognized by inputting a superimposed image combined into an image device 17 and sending image signals to a monitor 18 to display.

摘要： PROBLEM TO BE SOLVED: To improve the using efficiency of illumination light in a state that reduces the cost of a marking reader by adding a sapphire glass which is placed on the sliding surface of a reading object to a dustproof glass together with a transparent base plate such as a glass plate which is adhered at the light source side of the sapphire glass and has a refractive index smaller than that of the sapphire glass. SOLUTION: A dustproof sapphire glass 12 has a sapphire glass 70 having its extremely high intensity to the sliding scratches on an outer surface 12b forming a sliding surface of a reading object and also has a blue plate glass 71 serving as a base plate on an inner surface 12a forming a light source 41. The glass 70 is bonded to the glass 71 via an adhesive made of the ultraviolet hardening resin etc., with no air bubbles produced on the joint surface of both glasses. The glass 71 uses a material having a refractive index smaller than that of the glass 70. Thus, it's possible to improve the light using efficiency and to illuminate the reading object with high brightness by using the glass 71 having a small refractive index.

摘要： PROBLEM TO BE SOLVED: To provide a camera shutter where the stroke of the opening actuation of a shutter blade is suitably changed in accordance with aperture control by a diaphragm blade. SOLUTION: When the rotor 4 of a shutter driving motor M1 is reciprocatively rotated, the shutter blades 11 and 12 are relatively moved by a driving pin 5, so that an aperture part 1c (2b) for exposure is opened and closed. On the other hand, the diaphragm blade 13 is reciprocatively actuated by the driving pin 5 by the reciprocating rotation of the rotor 4 of the diaphragm driving motor M2, so that the diaphragm aperture part 13a is faced to the aperture part 1c (2b) and also a regulating part 13b is faced at the inside of the actuation locus of the shutter blade 11. Thus, when the diaphragm aperture part 13a is faced to the aperture part 1c (2b), the shutter blade 11 abuts on the regulating part 13b, and the stroke of the opening actuation of the shutter blades 11 and 12 are controlled.

摘要： PROBLEM TO BE SOLVED: To provide a lens mounting position adjusting mechanism whose adjusting operation is easy and which is constituted so that the mounting position of a lens is finely adjusted in an optical axis direction without changing the optical axis position of the lens in a barrel-shaped lens frame at the time of production. SOLUTION: At the time of assembly, the screw part 5a of a lens barrel 5 is screwed in the screw part 4b of an adjusting member 4, and then the screw part 4a of the member 4 is screwed in the screw part 3b of the lens frame 3. In the case of finely adjusting and deciding the position of the lens mounted at a barrel part 5b, a shaft member 6 is inserted in the hole of the lens barrel 5 first, and its tip is inserted in a hole formed at the projection part 3c of the lens frame 3. Thereafter, a tool is engaged with grooves 4c and 4c and rotated so as to make the lens barrel 5 advance/retreat in the optical axis direction without rotating the lens barrel 5 in accordance with the rotating direction of the member 4. As a result, the lens mounted at the barrel part 5b is finely adjusted in the optical axis direction and positioned without changing the optical axis position.

摘要： PROBLEM TO BE SOLVED: To exactly recognize an object position without being affected by the position shift of focusing lens and imaging element by irradiating a reading object with a reference light and recognizing the position shift of the reading object on a screen based on the position of the reference light. SOLUTION: A housing 9 is fixed to a photographing unit 4 so as to cover a shell 5, a light beam K emitted from a reference light source 13 placed at the inner wall is reflected on a half mirror 11 and focused on an electronic part 3 of the reading object sucked in a sucking nozzle 2 in the state separating the light source from the photographing system. Then, the reflection light from the electronic part 3 is taken in with CCD 7 via a focusing lens 6 to make it a reference light P for calibration and project on a monitor 8. At this moment, by adjusting in advance the positions of the center of the nozzle 2 and the reference light P, the position of the nozzle 2 hidden in the electronic part 3 can be recognized on the monitor 8 by the reference light P projected on the electronic part 3.
