  • Patent number: 10456035
    Abstract: An ophthalmic surgical microscope includes an observation optical system configured to guide observation luminous fluxes for a right eye and a left eye from an observation object to an imaging device, an actuator configured to move a position of the observation optical system in at least a direction intersecting with the observation luminous fluxes, a processor, and a memory storing computer-readable instructions. The computer readable instructions, when executed by the processor, cause the ophthalmic surgical microscope to cause a stereoscopic image display to display an observation image to be observed with a right eye of a user and an observation image to be observed with a left eye of the user, detect a position of the observation object with respect to the observation optical system, and correct a deviation in a relative position of the observation optical system with respect to the observation object.

  • Patent number: 5896774
    Abstract: A device, having a planetary gear and a single motor, in use for switching and transmitting a driving force of the motor to any one of station gears and for driving each station gear in both rotational directions. The operation of locking levers for preventing a planetary gear from revolving around a sun gear is controlled by a cam. The cam is actuated by a driving force of the motor. A spring frictionally connecting the cam and an output shaft of a speed reduction system is interposed therebetween, and a magnet is disposed so as to restrict the movement of the cam when the motor rotates. A sun gear is connected with the output shaft of the speed reduction system with a "play" or gap in order that the rotation of the sun gear is reversed behind time corresponding to the play when the rotation of the motor is reversed, thus making it possible to start actuating the cam earlier than the sun gear for making sure that the locking levers are shifted.

  • Patent number: 5481325
    Abstract: A cover-locking mechanism for locking a cover with respect to a cartridge compartment so that the cover is prevented from being opened when a film cartridge is accommodated inside the cartridge compartment with a film thereof being outside the film cartridge.The cover-locking mechanism is operated by using a driving force to drive either a film-feeding mechanism or a light-intercepting door of the cartridge disposed at an entrance/exit of the film thereof. If the mechanism is of a type of being operated by the driving force of the film-feeding mechanism, it is constructed to be controlled by a driving force to drive the film-feeding mechanism so that the cover is prevented from being opened when the film is outside the cartridge.

  • Patent number: 5410380
    Abstract: A film feeding apparatus of a camera using a film having two perforations in each frame. A perforation detecting lever has claws spaced at a predetermined distance apart from each other so that the distance therebetween is equal to the distance between the two perforations which are adjacent to each other across the boundary between frames. The perforation detecting lever engages the perforations and disengages therefrom in unison with an operation for feeding one frame to be performed after the proceeding frame is exposed to light. As a result, film feeding is allowed to proceed until both claws simultaneously engage two respective perforations in the film which occurs after the film has advanced one frame.

  • Patent number: 5351102
    Abstract: A camera using a film having a magnetic surface for recording magnetic data thereon. The camera includes a magnetic head for writing magnetic data onto the magnetic surface and for reading magnetic data recorded thereon. A pad movable with respect to the magnetic head is opposed to the magnetic head. The film is sandwiched between the pad and the magnetic head when magnetic data is written onto the magnetic surface of the film and the magnetic data recorded thereon is read. The pad is driven by a motor for driving a film feeding mechanism so that the pad moves away from the film feeding path when data writing and data reading is not carried out. A planetary gear mechanism connects the motor selectively to a pad driving mechanism and a film feeding mechanism.

  • Patent number: 5258793
    Abstract: A structure of a cartridge chamber and cover of a camera which uses a film cartridge. The cartridge chamber has a depth such that a predetermined end portion of a film cartridge is exposed along an axis of a spool in the cartridge when the film cartridge is accommodated in the cartridge chamber. Also provided is cover having a configuration for covering the end portion of the film cartridge accommodated in the cartridge chamber when the cover is closed. Thus, the end portion of the film cartridge is exposed when the cover is opened. Also, the cover is locked to restrain the cover from being opened when the cartridge chamber opening is downward and to enable the cover to be opened when the cartridge cover opening is upward. With this construction, the user can open the cover only when the opening of the cartridge is pointed upward in order to prevent the cartridge from dropping from the cartridge chamber inadvertently.

  • Patent number: 5070355
    Abstract: A camera capable of identifying photographing conditions causative of red-eye effect making the eyes of human pictures in a flash-photographed picture come out red, and recording the identified photographing conditions in an external memory provided on a film cartridge loaded thereon. The camera recognizes the possibility of occurrence of red-eye effect on the basis of the focal length of the camera lens, the object distance, the distance between the optical axis of the camera lens and the light source of the flash light device and the object brightness. When the photographing conditions are identified to be causative of red-eye effect, a warning is displayed and flash photographing is forbidden.
