A pressure sensor () includes a diaphragm () with a bottom formed of a thin-wall portion () and a pressure introducing joint (), in which an austenitic precipitation hardening Fe&#x2014;Ni heat resisting steel having high mechanical strength is used for the diaphragm (), while an austenitic stainless steel that is relatively inexpensive is used for the pressure introducing joint (). The diaphragm () and the pressure introducing joint () are integrated by welding, and Ni content of a weld portion is appropriately adjusted. Thereby, the pressure sensor () achieves high accuracy and reliability, and usage amount of the expensive austenitic precipitation hardening Fe&#x2014;Ni heat resisting steel can be minimized in manufacturing the pressure sensor (). Also, since the austenitic stainless steel has an excellent corrosion resistance, the pressure sensor () can be used in measurement of a fluid with high corrosiveness.

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). The camera may include a finder optical system for visually recognizing an image of an object, with the sliding member disposed in the vicinity of a film aperture. The slide member is disposed in a face-to-face position to the finder optical system with the film aperture being interposed therebetween.

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.

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.

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 addition, date, time and other information can also be imprinted onto the memory storage media. Picture taking will not be performed when it is not possible to accurately superimpose the reference scale and warning displays are generated.
