摘要:
A display apparatus in a camera for displaying photographic information using rotating elements. The display apparatus includes rotating pointers which rotate about display scales to display the photographic information. The display apparatus further includes a control unit which receives camera control information and in response to the control information, the control unit controls driving circuitry which causes the rotating display pointer to point to an index on the display scale representing the photographic information.

A display apparatus in a camera for displaying photographic information using rotating elements. The display apparatus includes a rotating setting dial to rotatively set photographic information, and a display unit including pointers and pointer scales to display the photographic information set by the rotating setting dial. The pointer rotates about a fixed pointer scale in order to indicate photographic information on the pointer scale as set by the rotating setting dial. The display apparatus further includes a detector to detect a direction of rotation of the rotating setting dial, a drive unit to rotate the pointer, and a control unit to control the drive unit to rotate the pointer in the same direction as the direction of the rotating setting dial detected by the detector. In addition, the display unit may include at least one pointer which is controlled by a stepping motor to rotate the pointer in only one direction, regardless of the direction of rotation of the rotating setting dial.

A camera having a multiple speed film driving mechanism that can accurately read film data on a film cartridge. The camera has a motor that drives a spool axis of the film cartridge, and a reading device that can read film data stored on a recording medium on the film cartridge. When the film cartridge is loaded into the camera, the reading device reads film data on the recording medium that is rotated together with the spool axis at a first speed. When film data reading is finished, the spool axis is rotated at a second speed to feed the film into the camera. A motor drive control circuit and CPU controls spool axis rotation at multiple speeds and directions.

A device (e.g., a camera) loaded with a film unit operates to detect a characteristic of the film unit, such as the state of an information part of the film unit. The detection result is used as a basis to control the performance of a further operation, such as a phototaking operation or a state-setting operation for the information part.

摘要:
A camera which switches between illuminating an external display and illuminating an internal display based on a specific photographic event, such as the pressing of the release button. The camera includes a first display, a first display illumination device which illuminates the first display, a second display, a second display illumination device which illuminates the second display, a control mechanism for controlling the first display illumination device and the second display illumination device so that the first display illumination device is not illuminating the first display when the second display illumination device is illuminating the second display and so that the second display illumination device is not illuminating the second display when the first display illumination device is illuminating the first display.
摘要:
An indicating apparatus of a camera, has an indicating unit, a driving unit and an adjusting unit. The indicating unit includes an indicating member capable of indicating any of a plurality of indicated positions. The driving unit drives the indicating member on the basis of information on photography of the camera. The adjusting unit is capable of adjusting the indicated position of the indicating member irrespective of the information on the present photography of the camera. Each indicated position corresponds to an item of information on the photography of the camera.

A camera is capable of displacing a phototaking optical system in the direction of the optical axis by a drive source such as motor and setting the optical system to a plurality of positions. The camera includes a photo-taking optical system, photographing position setting means producing a command signal, a drive source, position detecting means outputting a position signal corresponding to the position of the photo-taking optical system, discriminating means for discriminating the direction of movement of the phototaking optical system, and control means for stopping the drive source and setting the photo-taking optical system at a position corresponding to the command signal as soon as the position indicated by the position signal coincides with the position indicated by the command signal when the discriminating means is discriminating a predetermined first direction of movement, stopping the drive source at a position beyond the position indicated by the command signal and then driving the drive source so that the photo-taking optical system is moved in the first direction when the disciminating means is discriminating a second direction of movement differing from the first direction of movement, and stopping the drive source and setting the photo-taking optical system at the position corresponding to the command signal as soon as the position indicated by the position signal coincides with the position indicated by the command signal.
摘要:
A camera containing a lens barrier therein is comprised of a helicoid rotatable about the optic axis, a rectilinear barrel threadably engaged with the inner side of the helicoid and having a holding portion for a lens barrier holding a photo-taking lens and protecting the photo-taking lens, a guide plate extending in the direction of the optic axis and engaged with the rectilinear barrel to rectilinearly guide the same through a cut-away groove, and a lens barrier held in the lens barrier holding portion and opened and closed in front of the photo-taking lens. The guide plate and the lens barriers are designed so as to be capable of overlapping each other in the direction of the optic axis, and the guide plate is designed so as not to hamper the opening-closing of the lens barriers even when they are in the overlapping position.
