    摘要: A multi-beam type rangefinding method and device uses three LEDs arranged along a line perpendicular to a base line, and a PSD for receiving light reflected from three measurement regions of a photographic scene. In the gain determining procedure, a selected LED emits light at least once. In the rangefinding procedure, it emits light a plurality of times. Light reflected from an object is received by the PSD which outputs two channel signals. The two channel signals are amplified by two gain control amplifiers which are adjusted to have the same gain. The gain is adjusted to be an optimum value for the two channel output signal levels. Upon changing the gain, light projection by a selected LED is stopped until the output of each gain control amplifier becomes stable. If one of the two channel output signals saturates during the rangefinding procedure, the light projection/measurement is repeated at the same gain after a lapse of predetermined delay time. If the number of times when the output signal saturates becomes a predetermined number during the rangefinding procedure, the rangefinding procedure is recommenced.

    摘要: A CPU writes in a RAM various data obtained in a rangefinding procedure, e.g. offset values, gain values, data actually measured using a series of rangefinding LEDs, corresponding distance data obtained from each of the measurement data, and the optimum distance data used for setting a taking lens. When specifying an inspection mode, a microcomputer reads these written data out of the RAM to indicate them on an LCD numerically. Light emitting diode displays output the write data as light signals in intermittent light emission. To correct an error in the mounting position of the rangefinding LEDs, correction data are generated and written beforehand in an erasable ROM.

    摘要: A range finding device having a plurality of LEDs for projecting toward a scene to be photographed a plurality of spot beams of light disposed in a horizontal line, and a PSD for receiving light reflected from the object. Two channel signals from the PSD are amplified by gain control amplifiers and converted into digital signals. The two channel digital signals are obtained for each LED, and the ratio between the two digital signals is used for calculating a distance datum. Of a plurality of distance data obtained for respective LEDs, an optimum one is selected. For the calculation of a distance datum, there is used a microcomputer which controls an image taking sequence. The gain of the gain control amplifier is automatically adjusted by the measured data obtained in accordance with pulsed light emitted during the initial period of driving the LED. Digital signals obtained prior to the light emission of the LED are used for calculating an offset correction value. Each LED emits a pulsed light beam at a predetermined interval. An average value of digital signals for the pulsed light beams is used for calculating a distance datum. Several pulsed light beams during the initial period are not used for range finding or gain control. If the gain of the gain control amplifier is not proper, the range finding is interrupted and a distance datum specific to the then-existing gain value is used.

    摘要: An optical printer module has a film pack compartment that stores a film pack which stores an instant print film in a frame composed of a main frame, a subframe and a cover. The frame contains a claw mechanism and a spread mechanism that includes a pair of spread rollers. The claw mechanism feeds the instant print film out of the film pack while the instant print film is being exposed, and the spread rollers pinch the exposed instant print film fed out of the film pack by the claw mechanism to develop the exposed instant print film and feed the developed instant print film from the optical printer module. The whole surface of the frame shades the film, except for an opening for the film pack.

    摘要: A process for producing a hose having a connecting portion includes the steps of a connecting step, and a molding step. In the molding step, a dividable mold is employed in which a first sealing member and a second sealing member are retained so as to form a sealing ring. The sealing ring firmly retains a hose in the mold without pinching and damaging it. Further, the mating surfaces of the first sealing member and the second sealing member are disposed so as to deviate from the center of the sealing ring. Furthermore, a chucking member adapted for locally pressing the hose is disposed adjacent to the sealing ring. Moreover, a recessing portion communicating with the cavity of the mold by way of a narrow passage is formed and the first minimum pressure of the molding material, enabling to pass through the narrow passage, is set less than the sealing pressure exerted between the sealing ring and the hose and is set more than the second minimum pressure thereof, enabling to inhibit the short shot failures.
