  • Patent number: 5546150
    Abstract: An apparatus is provided with a movable cartridge casing capable of facilitating film cartridge loading and unloading operations. In a loading operation, the cartridge casing is positioned at a cartridge receiving position outside the body of the apparatus so that the film cartridge can easily be inserted in the cartridge casing, the cartridge casing containing the film cartridge is pushed into the body to an intermediate position where the film spool of the film cartridge is separated from a spool driving shaft, and then the cartridge casing is moved toward the spool driving shaft along a line substantially parallel to the axis of the spool driving shaft to bring the film spool into engagement with the spool driving shaft.

  • Patent number: 5467158
    Abstract: A film winding/rewinding mechanism of a camera driven by an ultrasonic wave motor. The winding driving section includes a cylindrical spool and a cylindrical first ultrasonic wave vibrator provided in the spool. A roller urged by a leaf spring is pressed against the peripheral surface of the spool, so that the peripheral surface of the vibrator contacts the inner surface of the spool at a point in the circumferential direction thereof. The film rewinding driving section includes a film rewinding fork, a cylindrical member mounted on the periphery of the rewinding fork, and a cylindrical second ultrasonic wave vibrator provided between the rewinding fork and the cylindrical member. The diameter of the outer circumference of the second ultrasonic wave vibrator is greater than the diameter of the outer circumference of the first vibrator.

  • Patent number: 5081482
    Abstract: An IC card suitably adapted to a camera as a small size device and a camera to which such IC card can be mounted appropriately. The IC card is formed as a rectangular plate of a size of about 20 mm.times.30 mm to 40 mm.times.60 mm so that it may be mounted on a camera. Contents of the IC card are or can be indicated on a front surface of the IC card. A plurality of connecting terminals for electric connection to a camera are disposed in a row on a rear surface along an edge of the IC card. A camera for use with such IC card has an IC card accommodating means provided thereon. Where the camera is a single lens reflex camera, the means may be located sidewardly of a pentagonal roof prism accommodating section on the top of the camera and include a lid member for opening or closing a card accommodating section thereof.

  • Patent number: 5032857
    Abstract: A camera system wherein a card accommodating device can be mounted on a body of a camera without increasing the overall size of the camera body and without deteriorating the appearance and convenience in use of the camera. The card accommodating device is mounted on the camera body for pivotal motion from and to a position at which it is fitted in a recessed spacing formed rearwardly of a battery accommodating chamber and sidewardly of a take-up spool chamber of the camera body. The card accommodating device at the position forms part of a side wall of the camera body. The card accommodating device comprises an outer lid unit for removably accommodating an IC card therein, and an inner lid unit mounted for movement and releasably arrested on the outer lid unit and having switch elements and electric signal transmitting contacts located thereon.

  • Patent number: 5025239
    Abstract: An electromagnetic actuator suitable for use in combination with the mechanisms of cameras and the like. The electromagnetic actuator has a single electromagnet, and first and second armatures disposed opposite to the opposite attracting surfaces of the electromagnet, respectively. The first armature actuates a first operating lever for operating the shutter release mechanism of a camera, and the second armature actuates a second operating lever for operating the diaphragm of the camera. The first armature is separated from the attracting surface and the second armature is in contact with the attracting surface while the electromagnet is not energized. When the electromagnet is energized, the first armature is attracted to the attracting surface to actuate the first operating lever for releasing the shutter.

  • Patent number: 4982210
    Abstract: A flash device in which a mechanism for shifting a light emitting section up and down and a mechanism for changing over the light distribution angle can be automatically controlled by means of a single motor and which occupies a comparatively small spacing when mounted on a camera. The flash device includes a bidirectional drive motor mounted in a body member, and a shiftable member having the light emitting section thereon. The shiftable member is shifted by rotation of the motor in either direction between a retracted inoperative position and a projected operative position. The light distribution angle of the light emitting section is changed over by continued energization of the motor after the shiftable member is moved from the inoperative to the operative position. A friction mechanism is interposed in a motion transmitting mechanism from the motor to the shiftable member.
