摘要： A photographic camera is provided with a cartridge chamber in which a film cartridge is loaded. A chamber lid is movable between an opening position in which it opens an entrance opening to the cartridge chamber and a closed position in which it closes the entrance opening. A lock lever is moved to a locking position in response to movement of the chamber lid to the closed position to lock the chamber lid in the closed position and is moved to an unlocking position to release the chamber lid in response to an operation for opening the chamber lid. The lock lever is urged toward the locking position by a spring. A lifter is disposed in a first position where it is brought into abutment against the film cartridge when the film cartridge is loaded in the cartridge chamber, is moved by the film cartridge in response to loading of the film cartridge in the cartridge chamber to a second position where it can be brought into abutment against the chamber lid when the chamber lid is moved to the closed position, and is moved, by the chamber lid in response to movement of the chamber lid to the closed position, to a third position where it is away from the film cartridge. the lifter is urged toward the first position by the spring which urges the lock lever.

摘要： The lens barrel cover of a camera is made separately from its front cover, whereby the center positions of the lens barrel and opening of the lens barrel cover can easily be aligned with each other. Also, since the insertion opening of the front cover is disposed as being shielded with the lens barrel cover, the insertion opening is not exposed to the exterior of the camera, whereby the appearance of the camera will not be spoiled even if the insertion opening and lens barrel positionally deviate from each other. Further, since the front cover is pressed toward the main body section as the lens barrel cover is being attached, no gap is formed between the front cover and the main body section.

摘要： In a finder, a movable lens is supported by a shaft and a guide plate respectively at both side edge portions thereof so as to keep a balance. The movable lens is moved accurately and smoothly. Also, the guide plate for supporting the side edge portion of the movable lens is separated from the frame. Accordingly, the movement of the movable lens can be smoothed when the machining accuracy of the guide plate is enhanced alone so as to support the movable lens at an accurate position.

摘要： A laser discharge tube having electrodes the peeling of which is reduced and a method of manufacturing electrodes of a laser discharge tube by which the peeling of the electrodes is reduced. The electrodes are adhered to the outside periphery of the tube wall of the laser discharge tube. The electrodes contain as components an electric conductive substance, an inorganic binder and boron nitride as a thermal expansion preventing substance for suppressing a coefficient of thermal expansion. When a silica glass tube is used as the laser discharge tube, the laser discharge tube has a coefficient of thermal expansion of +0.5.times.10.sup.-6. When the electrodes are mixed with boron nitride, the electrodes have a coefficient of thermal expansion of +2 to +7.times.10.sup.-6 and the coefficient of thermal expansion of the electrodes can be brought close to the that of the laser discharge tube by mixing boron nitride with the electrodes. Thus, the peeling of the electrodes caused by a difference of the coefficients of thermal expansion can be reduced.

摘要翻译： 具有其剥离电极的激光放电管被减少，以及制造电极剥离的激光放电管的电极的制造方法。 电极粘附到激光放电管的管壁的外周。 这些电极包含导电物质，无机粘合剂和氮化硼作为组分，作为用于抑制热膨胀系数的热膨胀防止物质。 当使用石英玻璃管作为激光放电管时，激光放电管的热膨胀系数为+ 0.5×10 -6。 当电极与氮化硼混合时，电极的热膨胀系数为+2〜+ 7×10-6，电极的热膨胀系数可以接近于激光放电管的热膨胀系数，通过混合氮化硼 与电极。 因此，可以降低由热膨胀系数的差异引起的电极的剥离。
