Abstract: PURPOSE:To efficiently execute a display without enlarging the space of a display part, by constituting the title device so that information related to an exposure value such as a diaphragm value, shutter speed, and the meter display of a photometric value, etc., is displayed on only the inside of a finder. CONSTITUTION:The display device of a camera having a finder inside display means 700 for displaying various information on the inside of a finder, and a body upper part display means 600 for displaying various information on the outside surface of a camera body is constituted so that information related to an exposure value such as the diaphragm value and the shutter speed is displayed on only the finder inside display means 700. In this way, it becomes unnecessary to place a display segment for displaying the exposure value on the display means on the outside surface of the camera body, and this display means can be made smaller. Also, it is possible to make the display easily visible by enlarging the size of each display segment instead of making the display means small, and the display can be executed more efficiently in a limited display space.

Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To obtain an optical pickup which can be assembled easily while preventing external impact effectively by providing a damping means for preventing vibration of a holder between the holder and a yoke plate. SOLUTION: Since the distances between a first damping yoke 136 and first and second supporting pieces 116, 118 are shorter than the length of first and second dampers 120, 122, the first and second dampers 120, 122 are fixed while being bent. Driving characteristics of an objective lens 112 are enhanced by coupling the first and second dampers 120, 322 under a state where a compressive force acts between the first and second supporting pieces 116, 118 and the first damping yoke 136. When the pickup is subjected to an external impact under that state, vibration energy of the holder 114 is absorbed by the dampers 120, 122 and the vibration of the holder 114 is damped.

Filed: 1978-06-28
Abstract: PURPOSE: To make the magnetism of magnetic latent images stronger by coating magnetic powder on the specified belt substrate thereby forming a magnetic electrostatic latent image carrier.  
     CONSTITUTION: When latent-image-forming magnetic powder is evenly coated to the spedified thickness on the surface of a belt using metal induced magnetic material as its substrate 20 in such a manner that its magnetization easy axes become perpendicular to the substrate 20, then a magnetic latent image forming layer 21 is formed. If this belt 2 is used as a magnetic latent image carrier, the substrate 20 is metal material and has heat resistance and therefore it does not cause deformation of the belt 2 of good shape stability through heating before writing by a write head 22. Hence, when it is cooled after it has been subjected to writing under a high temperature state, the magnetic latent images of strong magnetic force may be formed by using the head 22 of weak magnetic force.
