Abstract: A camera having a lens barrier unit that opens without encountering obstructions in response to the operation of an operating member and without increasing the size of the lens barrel of the camera. The lens barrier unit covers the front surface of a photographic lens in a closed position, and moves clear of the front surface of the photographic lens in an open position. A sliding member, which is a separate member from the operating member, mechanically drives the lens barrier unit to an open position in response to the movement of an operating member by means of the operation for photographic preparation (e.g., when the camera is switched ON), and drives the lens barrier unit to a closed position, by coupling to the movement of the photographic lens unit while moving from the extended position to the retracted position (e.g., when the camera is switched OFF).

Abstract: A camera for use with interchangeable lens barrels that can be attached to and detached from the camera body has a drive mechanism that provides the generating source for the drive power of drive elements inside each lens barrel built into the camera body. The connecting structure that provides a connection between the camera body and lens barrels varies according to the type of lens barrel, for example, whether the lens barrel contains a fixed focal length lens or a variable focal length lens. So, the functions realized by the drive of the drive elements from the drive mechanism vary according to the type of lens barrel.

Abstract: A zoom lens barrel includes at least two lens groups, a linear movement guide tube for guiding a linear movement of the lens groups along the optical axis and a cam tube for reciprocating the lens groups along the optical axis. The guide tube has a guiding portion formed on a film side end portion of the guide tube and extends in parallel with a film surface.

Abstract: A camera having multiple display functions and/or a date imprinting function wherein the display can alternately switch between displaying the date and the film frame number. The frame number is displayed when winding blank film and the date is displayed at other times. The display also has an indicator which lights up or flashes to indicate the status of the camera power source. The display also shows the date and this date can be imprinted on film when a photograph is taken. The date can be imprinted whether or not the camera is in a date correction mode when the photograph is taken. A multiple function button is used to change photographic information shown on the display, wherein different functions correspond to different camera modes. Adequate safeguards are therefore provided by this camera to prevent accidental changing of information.

Abstract: A camera, such as a video camera or other electrically recordable camera, has scale imprintable capabilities and a method for imprinting a scale onto memory storage media. The camera and method imprints, optically or electrically, a standard scale on memory storage media for the purpose of estimating the size of a subject image. A photographic magnification calculation circuit calculates the photographic magnification based on a subject distance, and a reference scale setting circuit sets a reference scale for the purpose of estimating the size of the subject image on the memory storage media regardless of the magnification during picture taking or print size. An imprinting circuit imprints, optically or electrically, the reference scale onto the memory storage media in accordance with the reference scale setting circuit, and only when needed or wanted. The reference scale can be imprinted in a vertical or horizontal direction in accordance with a mode selection switch.

In a preferred embodiment, when the camera is in the continuous photography mode and the user has inhibited the flash device, the inhibition of the flash device is maintained upon completion of continuous photography. One-frame photography may be performed while the camera is in the continuous photography mode, and while maintaining inhibition of the flash device, by momentary depression of the shutter release button. If the camera is operated in the one-frame photography mode and the flash device is inhibited, inhibition of the flash device is automatically cancelled after each exposure.
