Abstract: A mounting device on a camera has a mounting member to fit with an accessory so as to mount the accessory on the camera by sliding it. The mounting member which is molded out of plastic in one piece has eaves-like portions overhanging from an upper portion thereof in opposite directions intersecting perpendicularly to a mounting direction of the accessory, thus having a generally T-shaped cross section. The mounting member has a groove running in the mounting direction at a top central portion for receiving a projecting portion of the accessory so as to determine a horizontal (lateral) position of the accessory relative to the camera. The eaves-like portions receive mating members of the accessory thereunder so as to determine a vertical position of the accessory relative to the camera.

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.

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.

Abstract: A viewfinder assembly which comprises a viewfinding mirror module of one-piece construction including a pair of major roof mirrors laid at a predetermined acute angle (90.degree.) relative to each other, side walls continued from respective lower edges of the roof mirrors to support such roof mirrors and an eyepiece support frame positioned rearwardly of the viewfinding mirror module. Each of the side walls has a lower edge formed integrally with elastic fitting pawls for the fitting of the viewfinding mirror module to the camera body. In order to mount the viewfinding mirror module, the viewfinding mirror module is first mounted on the viewfinder holder with the fitting pawls engaged in holes in the viewfinder holder.

Abstract: Disclosed are exposure data indicating means for an exchangeable lens type camera which is selectively settable for operation in either a diaphragm priority automatic shutter speed control mode or a shutter speed priority automatic diaphragm control mode and which includes structure enabling indication of an f-number representative of an automatically controlled diaphragm aperture when the maximum f-number of the particular exchangeable lens mounted on the camera has been preset. The indicating means provides an indication within a finder view field of both a preset f-number and a preselected shutter speed when the camera is set to operate in the automatic diaphragm control mode and of only a preset f-number when the camera is set to operate in the automatic shutter speed control mode. The indicating means includes a view-finder and two separate optical arrangements adapted for directing light to introduce visible information relating to set f-number and selected shutter speed into the view-finder view field.
