摘要： An automatic focusing camera includes a sensor for detecting an amount and a direction of difference between an image forming position of light from an object being photographed and a film surface to drive a taking lens in response to the measured outputs and focus determining capability which gives a decision of in-focus when the amount of difference is less than a first automatic focusing threshold. A focusing operation is achieved such that, comparing the amount of difference determined by the sensor with a second automatic focusing threshold of a standard value which is larger than the first automatic focusing threshold, when the amount is less than the second threshold and a direction of difference last measured and that presently measured are the same, a taking lens driving is continued to complete a focusing operation and when the directions are different from each other, the measurement is resumed after the next driving of the taking lens even when the amount is less than the second threshold.

摘要： A lens drive apparatus includes a manual operating member. A pulse generator produces pulses as the operating member is moved. Based on a phase shift between the pulses, the speed with which and the direction in which the operating member is moved are detected. Control circuitry delivers a drive signal to a lens driving motor in accordance with the speed of movement signal and the direction of movement signal. A relationship between the speed of movement signal and the drive signal which prevails in the control circuitry can be modified, allowing a high or low level of the drive output to the motor to be selected with respect to the speed of movement and also allowing the speed with which and the direction in which the motor is driven, thus enabling the control circuitry to control the motor.

摘要： In a camera system according to the invention, a camera body and an interchangeable lens have respective identification data tables that are congruous with each other. As an appropriate data address is indicated to the interchangeable lens by the camera body, an identification data that is stored in the identification data storage section and corresponds to the indicated address is transmitted from the interchangeable lens to the camera body. The identification data judging section of the camera body compares the identification data transmitted back from the interchangeable lens and the identification data that is stored in the identification data storage section and corresponds to the address. As a result, it is determined if the dedicated accessory device is mounted on the camera body or not.

摘要： The present invention provides a user-friendly camera having a silver-salt picture-taking function and an electronic-image pickup function. The camera includes a silver-salt picture-taking unit and an electronic-image pickup unit. The electronic-image pickup unit picks up an electronic image, which is almost equivalent to a subject image exposed to a silver-salt film, in synchronization with the exposure to the silver-salt film in the silver-salt picture-taking unit. Prior to the exposure, a control circuit causes a battery check circuit to check a power supply battery and causes a determination circuit to determine a result of the battery check while referring to a determination-level storage circuit, thereby properly controlling the silver-salt picture-taking unit and the electronic-image pickup unit so as to prevent the electronic-image pickup unit from performing its pickup operation in the subsequent picture-taking operations.

摘要： A film cartridge in which a supply spool incorporated in a cartridge body is rotated to supply a film wound on the supply spool out of the cartridge body. A film supply unit rotates the supply spool to supply the film out of the film cartridge. A first control unit controls the film supply unit such that a supply operation of the film is started in response to a closing operation of the rear cover of a camera body. A film take-up unit takes up the film supplied by the film supply unit. A second control unit controls the film take-up unit to operate the film take-up unit upon completion of the supply operation of the film performed by the film supply unit. A third control unit interrupts a take-up operation of the film performed by the film take-up unit and reoperates the film supply unit when the take-up operation of the film is impossible during the take-up operation of the film performed by the film take-up unit.

摘要： In a diaphragm control apparatus of a camera for opening and closing aperture blades using a stepping motor, a step-out status of the stepping motor is detected if an open detecting switch for detecting a full-open status of the aperture blades does not function after a predetermined number of drive pulses necessary for resetting the aperture blades to a full-open position are supplied to the stepping motor. Normally, the stepping motor is subjected to such a slow-up control that the continuing duration of the energizing step (pulse width of an energizing pulse) is gradually reduced from the time the motor has been activated to increase a pulse rate and a driving speed. When the step-out status is detected, the pulse rate of the energizing pulse is set constant, and the driving speed of the stepping motor thereafter is fixed to a constant low speed to provide high-torque driving, and opening the aperture blades to the full-open position. Thereafter, when the aperture is closed to a given aperture value, the slow-up control is executed again, however, the pulse width of the energizing pulse is set lower than that used before detection of the step-out status, thus increasing the driving torque.
