Abstract: A camera having a manually actuable switch for temporarily shifting the camera to an optimum exposure value so that exposure factors, based upon a manually set shutter speed and a manually set aperture value, are replaced by optimum exposure factors based upon a metered brightness of the object to be photographed when the camera is set to a non-program exposure mode. A clear button associated with the camera functions as a manually actuable switch for temporarily shifting an exposure mode of the camera to another exposure mode when the camera is set to a hyper-manual exposure mode. In the hyper-manual exposure mode, a photographer sets exposure factors by actuating a Tv electronic dial and an Av electronic dial. Actuation of the clear button when the camera is set to the hyper-manual exposure mode causes the set exposure factors to be replaced with optimum exposure factors that are automatically calculated in accordance with an object brightness Bv.

Abstract: In representing a depth of field in a camera, the depth of field is displayed on the basis of the magnitude of a field depth feeling Df which corresponds to human feeling. The field depth feeling Df is obtained by proccesing at least one of a depth of field on calculation, an object distance, a lens hypen-focal length, a diameter of permissible circle of confusion, a lens aperture value and a lens focal length.

Abstract: An exposure control apparatus of a camera having a photometer for detecting a brightness of an object to be taken, an exposure value calculator for calculating an optimum exposure value in accordance with the object brightness, and an exposure factor setting device for setting a pair of exposure factors having a shutter speed and a diaphragm value, including an exposure factor manual setting device, a specific program exposure mode in which the exposure factors corresponding to the optimum exposure values are automatically set, and an exposure factor modifying device for enabling the exposure factor manual setting device to manually set one of the exposure factors when the exposure factor manual setting device is actuated in the specific program exposure mode.

Abstract: An exposure control apparatus of a camera, wherein a pair of exposure factors that include a shutter speed and a diaphragm value can be manually and independently set. Furthermore, in the exposure control apparatus, an exposure value determined in accordance with the exposure factors can be locked, and one of the exposure factors can be varied, based on the locked exposure value, when the other exposure factor is varied by the associated manual setting means.

Abstract: A blocked isocyanate group-containing electrocoating composition comprising at least one dialkyltin aromatic carboxylate and at least one bismuth or zirconium compound as a combined curing catalyst. This electrocoating composition gives an electrocoating film superior in corrosion resistance and low-temperature curability and has good bath stability over an extended period.

Abstract: An exposure control apparatus of a camera, in which at least one of a pair of exposure factors that include a shutter speed and a diaphragm value is variable. An exposure factor setting device sets at least one variable exposure factor, while a limit value setting device varies and sets at least one upper and lower limit value of the exposure factor.

Abstract: An endless tape transport apparatus is comprised of a tape transport unit having a tape feeding device for transporting an endless tape, a tape compartment unit in which the endless tape is housed, the endless tape being transported around the tape transport unit and the tape compartment unit in a loop fashion, and a tape attracting device disposed near the tape feeding device at its position in which the tape attracting device contacts the endless tape, wherein the tape attracting device is driven to attract the endless tape when the endless tape stops running.

Abstract: An apparatus for indicating photographing conditions within a finder of a camera, including at least one indicator which has a plurality of indicating elements and which represent a single symbol or figure as a whole in the finder field of view, each of the indicating elements indicating an associated photographing condition.

Abstract: An endless tape storage apparatus has a casing defining a chamber for storing the endless tape. The casing defines an inlet through which the tape is introduced and an outlet through which the tape is withdrawn. A movable section is associated with the inlet, storing the tape in folded form and transferring the tape toward the outlet. A stationary section is provided downstream of the movable section for decelerating the transfer speed of the tape and for adjusting accumulation of the transferred tape and feeding the tape toward the outlet in unfolded form.

Abstract: A single-lens reflex camera with a flash unit built into the camera body above the viewing pentaprism. The unit is movable from an operating position to a non-operating position, preferably enclosed in the camera body. The built-in flash unit may be automatically closed by inserting an external flash in a flash shoe. A display panel may be included on the top of the flash unit housing.

Abstract: A pop-up flash unit 20 for an SLR camera includes an integral auxiliary light emitting device 26 for projecting a predetermined pattern along the camera lens axis to provide sufficient auto-focusing contrast. A triangular prism 60 forms a window in a front wall 16a of the flash unit chamber 16 confronting the condenser lens 25 of the auxiliary light emitting device such that the predetermined pattern projected by the downwardly angled emitting device, when the flash unit is retracted, is bent upwardly to still fall along the camera lens axis.

Abstract: In representing a depth of field in a camera, the depth of field is displayed on the basis of the magnitude of a field depth feeling Df, which corresponds to human feeling and sensitivity. The field depth feeling Df is obtained by processing at least one of a calculated depth of field, an object distance, a lens hyper-focal length, a diameter of a permissible circle of confusion, a lens aperture value and a lens focal length.

Abstract: An indicating apparatus of photographing conditions within a finder of a camera, including at least one composite indicator symbol which has a plurality of indicating elements and which represents a single symbol or figure as a whole in the finder field of view, said composite indicator symbol indicating the associated photographing conditions.

Abstract: A single-lens reflex camera has a finder device in which rays of light of an object to be photographed are reflected by a mirror to form an image of the object on a focusing glass, an information indicating apparatus within the finder device which can project photographing information represented by a letter or a figure or other symbol onto the focusing glass, an indication control circuit which controls the information to be indicated in the information indicating apparatus, and an information indicating switch for turning the information projector ON and OFF.

Abstract: A switching device comprising a rubber switch, an operating member displaceable between at least two operative positions and a neutral position, and a cooperating member shiftable between the at least two cooperative positions and neutral position in response to displacement of the operating member. The operating member and the cooperating member are held in their neutral position due to the resilience of the rubber switch, while one contact is brought into engagement with a corresponding conductive element in the rubber switch when the corresponding cooperating member is shifted to one of the cooperative positions in response to the displacement of the operating member against the resilience of the rubber switch.

Abstract: An electric device with an operation indicating light has a base and a case transversely divisible in a main frame and a case cover. The main frame is fitted to the base at one open end of the frame. A resin material is injected into the space provided by the base and the main frame. The case cover is fitted to the other open end of the main frame so that an operating indicating lamp can be seen through an indicating hole in the case cover. Thus, the device can be easily assembled, and the resin material does not leak from the gap between the operation indicating lamp and the indicating hole. Cracks are prevented from developing in the solder connecting the lamp to the circuit board. In addition, the lamp can be positioned at a high precision because no packing is required to prevent resin leakage.
