To shoot a still picture and a moving picture simultaneously, a light beam having passed through a taking lens is split by a half-mirror into two light beams so that one of the split light beams is directed to silver halide film and the other is directed to a CCD. An image captured by the CCD is displayed on a viewfinder. Focus condition of an image on the silver halide film is detected by the phase-difference detection method and focus condition of an image on CCD is detected by the contrast detection method so that, based on detection results, the focus of the taking lens or of a relay optical system is adjusted to obtain a well-focused image. When focus condition detection by one method is impossible, results of focus condition detection by the other method are used to adjust the focus.

Camera

A camera divides a light beam having passed through a taking lens unit into two light beams. One light beam forms an image on a silver salt film. Another light beam forms an image on a CCD. A light path for said another light beam is provided with an aperture diaphragm. The taking lens unit has an aperture diaphragm. Said two aperture diaphragms are correlatively controlled by a controller incorporated in the camera.

A flexible printed circuit board for use in a display unit of a camera, which includes a flexible substrate with a printed circuit pattern, a die of an integrated circuit chip mounted on said substrate for driving the display drive, a plurality of wires, and resin sealant for covering said integrated circuit chip. The flexible substrate has first terminals to be in contact with a display device and second terminals in electric connections to said first terminals, respectively. The die of the integrated circuit chip includes a plurality of connecting terminals. The plurality of wires are for bonding said connecting terminals of the integrated circuit chip to said second terminals of said printed circuit pattern.

Printed circuit board

Disclosed are film cartridges having improved digital code patterns, films having improved digital signal means, and cameras adapted for use with the film cartridges or the films. The improved code patterns include bits with different weights and a bit which is made conductive with at least one of the bits with the different weights. One of the cameras disclosed is provided with a reading device on a spool so that the reading device can continuously read the signal means at a front tip of a leader portion of the film throughout the duration in which the film is wound around the spool. Another camera disclosed is adapted to read the code patterns on the film cartridge upon insertion of the film cartridge into a cartridge chamber. Various camera circuits are proposed, in one of which decimal or fractional APEX values of read film speeds are converted to outputs with weights of 1/2, 1/4 and 1/8 for digital calculation and in another of which film speeds divided by 1/3 Ev steps are automatically set by being grouped into one of high, middle and low film speed ranges.

Film cartridges, films and cameras adapted for use therewith

A printed circuit board is plated through the steps of providing a printed circuit board, covering at least a predetermined portion to be plated of the printed circuit board with a mask, sealing tightly the periphery of the concavity by sandwiching a sealing material between the mask and the circuit board, providing an electric contact piece, filling up the space with plating solution, connecting the electric contact piece to a power supply, and supplying a plating electric current to the predetermined portion to be plated of the printed circuit board.

Process for plating a printed circuit board

A method of making a printed circuit board includes providing a substrate coated with a conductive layer, developing a first photoresist layer on the conductive layer to define a first conductive pattern of the desired circuit configuration having a plurality of discontinuous segments, and a second conductive pattern interconnecting the discontinuous segments of the desired circuit configuration. A second layer of photoresist is positioned across the whole surface of the substrate except at least a selected portion of the first conductive pattern, and the substrate is electrically activated during a coating process for depositing conductive material on the selected portion of the first conductive pattern. The first conductive pattern is subsequently coated with photoresist, and the second conductive pattern, which is now exposed on the substrate, is subject to an etching process to effectively remove all of the second conductive pattern.

Process for producing a printed circuit board

A frame member is bonded on a base plate having a plurality of electrical contacts thereon. The frame member includes a plurality of apertures corresponding to the electrical contacts. Bonding means bonding the frame member on the base plate is formed by a waterproof double faced bonding member including a waterproof sheet and waterproof bonding agent applied to both sides of the sheet, the double faced bonding member separates the electrical contacts from each other to prevent accidential conduction between the adjacent electrical contacts due to a water drop.

A photographic camera of a type utilizing a roll of film comprises a camera back lid, a take-up spool for taking up the film therearound, and a plurality of switches incorporated in the take-up spool. The switches built in the take-up spool are all closed, when the film is turned around the spool, to generate a signal inidcative of the fact that the film has no doubt been secured to the spool. An electric circuit is also provided for disabling the film wind-up so long as the camera back lid has not yet been closed even though the film has already loaded in the camera.
