Disclosed is a lens-fitted photographic film unit containing a roll of unexposed photographic film. The lens-fitted photo film unit uses a specific battery of a different size or shape from conventional standardized batteries. A hollow protrusion is formed in a battery holding room. A hollow of the hollow protrusion joins with a dark room for the photographic film. If the hollow protrusion is cut away with the intention to put a conventional battery in the battery holding room, the light-tightness of the dark room is destroyed. When a cartridge chamber bottom lid is opened to remove a film cartridge, an interconnection lever transmits the opening movement of the lid to a sliding plate. Then the sliding plate turns a charge switch of a flash circuit ON, and locks the charge switch in the ON position.

A camera body of an instant camera is provided with four light sources LED1 to LED4 for a display. The four light sources LED1 to LED4 flash on and off in mutually different display modes in accordance with the state of progress of a series of processing of an exposure operation, a developing operation and a delivery operation which is carried out in accordance with one time photographic operation. This feature makes it possible to exactly inform a user of the state of progress of a series of processing.

When a lens unit is to be mounted, the lens unit is moved downward along guide grooves, whereby an opening portion cover is also pushed down counter to an elongation force of coil springs, the lens unit is mounted to a camera body, and the opening portion cover is moved to an open position. When the lens unit is to be removed, the lens unit is moved along the guide grooves, whereby engagement with the guide grooves is released. Because the opening cover portion is urged from the open position to a closed position by the coil spring at this time, the opening portion cover is moved with the lens unit along the guide grooves and fixed at the closed position.

There is disclosed a distance measuring equipment capable of performing efficiently a greater accuracy of focusing without troubling an operator, and a camera incorporating thereinto such a distance measuring equipment. By the use of the first focusing algorithm switches 61, 62 and 63 set up to the turn-off state, the turn-off state and the contact 62a side, respectively, so that AF-dedicated photo detector circuit 40 performs once a ratio arithmetic processing in accordance with photo-currents I1 and I2 from the PSD 30. In case of the short distance area, they are dealt with as the focusing data. In case of the middle distance area, the ratio arithmetic processing is performed by n times. In case of the long distance area, by the use of the second focusing algorithm switches 61, 62 and 63 set up to the turn-off state, the turn-on state and the contact 62b side, respectively, so that the ratio arithmetic processing is performed in accordance with the photo-current I1 and the constant current Ir from the constant current source 50. In case of the longest distance area, by the use of the third focusing algorithm switches 61, 62 and 63 set up to the turn-on state, the turn-off state and the contact 62b side, respectively, so that the light quantity arithmetic processing is performed in accordance with the additional values of the photo-currents I1 and I2 and the constant current Ir to determine focusing data.

A lens-fitted photographic film package comprising a light-tight film casing having an exposure opening, a rolled film disposed on one side of the exposure opening in the light-tight casing, a removable light-tight container having a film winding spool therein disposed on the other side of the exposure opening in the light-tight film casing, and an externally operable film winding member for winding the rolled film around said film winding spool of the light-tight film container. The lens-fitted photographic film package is assembled by the steps of winding film withdrawn from a light-tight film container in a roll in a darkroom; loading the rolled film and the light-tight film container in separate respective receiving chambers formed in a main body section of the lens-fitted photographic film package; and fixing a back cover section to the main body section so as to assemble light-tightly the lens-fitted photographic film package.

A lens-fitted photographic film package comprises a light-tight film case having exposure structure, a rolled film in a film roll receiving chamber disposed on one side of an exposure frame in the light-tight case, and a removable film container having a film winding spool therein disposed on the other side of the exposure frame in the light-tight film case. A member is provided for causing the film to be advanced smoothly without getting scratched, for preventing the film roll from becoming loose, and for preventing the film from being gouged by a film exit slot of the film roll receiving chamber.

A photographic film package has a taking lens, an exposure member, and a rolled film, with their associated elements, contained in a light-tight film container as a unit. The taking lens consists of either an aspherical or a spherical single-element lens preferably made of plastic material and is designed to have a focal length f and a lens speed F defined by the following conditions:F.gtoreq.f.sup.2 /150F.gtoreq.34.3-0.75fF.ltoreq.16

A digital camera is composed of a camera body and a lens unit removebly attached to the camera body. When the lens unit is attached to the camera body, the lens unit and camera body send and receive control signals by antennas and wireless I/Fs each disposed on the lens unit and the camera body, respectively. In addition, data of the image captured with the lens unit is sent to the camera body by serial drivers, each disposed on the lens unit and the camera body, through connection contacts that electrically connect the lens unit and the camera body. When the lens unit is detached from the camera body, on the other hand, the control signals are sent and received by the antennas and the wireless I/Fs, and the image data is sent by the wireless communication.

A cellular phone has a black-and-white LCD that displays characters and communication information and a color LCD that displays an image. The image and the characters are displayed on the separate LCDs. Thus, the characters are not superimposed on the image, and they are easy to see. When the image is not needed (the user is not using the phone or the user is talking on the phone), only the black-and-white LCD displays the characters and the color LCD is turned off to save energy.
