Abstract: The present invention relates to a barrier member slidably movable along the surface of a camera to a closing position for covering a lens barrel of a camera body and to an opening position for letting the lens barrel be exposed. The camera includes a pressing member for pressing the barrier member from the side of the camera body, and regulating the slide movement of the barrier member in the closing and opening positions. In the camera of the present invention, the barrier member is provided with a guide member abutting on the pressing member at a plurality of points with the center of the pressing member being interposed therebetween in a direction along the surface of the camera and in a direction orthogonal to a slide moving direction of the barrier member, thereby eliminating a backlash of the barrier member.

Abstract: A camera includes a flash device movable between a withdrawn position, in which the flash device is received in a camera body, and an in-use position, in which the flash device protrudes from the camera body, an illumination-angle-varying mechanism for changing the illumination angle of the flash device, a lens barrel which is movable for magnification variation, and an operation-linkage mechanism serving, in mechanical linkage with the movement of the lens barrel, to move the flash device from the withdrawn position to the in-use position and to operate the illumination-angle-varying mechanism while the flash device is moving from the withdrawn position to the in-use position.

Abstract: A roller adapted to be rotatably mounted on a bushing of each link assembly of a chain comprises a split roller composed of two roller segments assembled together. The split roller can be easily mounted on the bushing from a radial direction of the bushing even though the bushing is integrally formed with links to form a single link assembly. The link assembly has a one-piece structure and hence is improved in strength and rigidity. The bushing of the link assembly is free from damage or break even when the chain is subjected to a great tensile force.

Abstract: A camera includes a flash light emitting part arranged to be movable between a stowed position and a usage position, a first lever member arranged to swing in such a way as to cause the flash light emitting part to move from the stowed position to the usage position and from the usage position to the stowed position, a second lever member arranged to swing in such a way as to vary an illuminating angle of the flash light emitting part by moving a part of the flash light emitting part, when the flash light emitting part is in the usage position, and a rotating member arranged to rotate according to movement of a lens barrel, wherein a first engaging part arranged to engage the first lever member and a second engaging part arranged to engage the second lever member are formed at the rotating member.

Abstract: A camera includes a flash device movable between a withdrawn position, in which the flash device is received in a camera body, and an in-use position, in which the flash device protrudes from the camera body, an illumination-angle-varying mechanism for changing the illumination angle of the flash device, a lens barrel which is movable for magnification variation, and an operation-linkage mechanism serving, in mechanical linkage with the movement of the lens barrel, to move the flash device from the withdrawn position to the in-use position and to operate the illumination-angle-varying mechanism while the flash device is moving from the withdrawn position to the in-use position.

Abstract: A camera includes a flash emission part arranged to move between a stowage position and a usage position, an operation member capable of being displaced by a sliding operation in a predetermined direction, and a transmission member which transmits to the flash emission part an amount of displacement of the operation member caused by the sliding operation, wherein the transmission member enlarges an amount of the sliding operation on the operation member and transmits the enlarged amount of the sliding operation to the flash emission part, so that the flash emission part is moved greater than the amount of displacement of the operation member.

Abstract: The present invention relates to a gas safety control system for supplying a gas that is forwarded from a gas supply source through an inspection meter to one or more gas appliances. The inspection meter comprises a cutoff valve for cutting off supply of the gas from the gas supply source, a detection unit for detecting such abnormal condition as gas leakage and abnormal flow rate of the gas, a valve control unit for actuating the cutoff valve when the detection unit detects an abnormality and a meter communication unit for outputting cutoff information indicating that the supply of gas is cut off by the cutoff valve. The gas appliance comprises an appliance communication unit for communicating with the meter communication unit and a combustion disabling unit for switching the gas appliance to a combustion disabled state, if it is in a combustion enabled state, when the cutoff information is received through the appliance communication unit.

Abstract: An imprinting apparatus for use in a camera having an imprinting device including a date information imprinting mode for imprinting date information, time information, or the like on a recording medium, and a message information imprinting mode for imprinting message information formed of alphanumeric characters, graphic designs or the like, or a message in the message information in one language being changed into a message in a different language if necessary, and an operating device for performing different operations on the imprinting device using the same operating member with respect to each of the date information imprinting mode and the message information imprinting mode.

Abstract: A camera having a flash device and a film accommodating chamber includes a flash emitting unit arranged to be movable between a use position and a stowage position, a driving part arranged to drive a lens sleeve so as to move an optical element disposed within the lens sleeve, a first member arranged to move in association with a movement of the lens sleeve, a second member arranged to drive the flash emitting unit, and a spring member arranged to interconnect the first member and the second member to transmit a movement of the first member to the second member, wherein the spring member is located between the lens sleeve and the film accommodating chamber.

Abstract: In a drop-in loading type camera, in which a film is loaded by dropping a film cartridge in a cartridge chamber from the axial direction of the cartridge, it has holding means which obliquely holds the film cartridge until the film leader is dropped in at a position beyond the aperture so that the film leader is dropped in later than the cartridge proper when dropping the film cartridge into the cartridge chamber.

Abstract: A pen recorder for writing characters and graphic patterns with recording pens on a sheet of recording paper by moving the recording pens in an X-axis direction and moving the sheet of recording paper in a Y-axis direction. When a desired key on a keyboard is depressed, the recording pens and the sheet of recording paper are moved to write a character corresponding to the depressed key on the sheet of recording paper. The size of the character can relatively freely be selected by operation switches for selecting horizontal and vertical character sizes. The pen recorder is automatically controlled for the same operability when the character size is changed in any of horizontal and vertical directions. Where the character size is changed horizontally, an alarm is issued prior to the completion of recording in a recording position a prescribed number of characters prior to a preset right margin.

Abstract: Disclosed is an automatic cassette loading apparatus which comprises a motor and a first sensing means for detecting when a cassette is placed in a first position to energize the motor. A counter is provided for counting clock pulses in response to the energization of the motor and generating an output signal when the counted clock pulses reach a predetermined value. A second sensing means is provided for detecting when the cassette is moved to a second, tape-operating position. The loading apparatus further includes a mechanism driven by the motor for moving the cassette from the first position to the second position and restoring the cassette to the first position and beyond to de-energize the motor when the output signal of the counter is generated prior to the detection of the cassette in the second position.
