An electric connector for camera is adapted to form an electric connection between an electric device within a taking lens barrel and an electric device within a finder system of the camera. The connector is disposed between the mount for mounting the lens barrel and the holder for mounting the finder system. The connector comprises first and second contacts. The first contact is connectable to the electric device in the lens barrel when the latter is mounted. The second contact is in electric connection with the first contact and connectable to the electric device in the finder system when the latter is mounted.

A device for electrically connecting a lens barrel and a camera body includes a connector provided integrally with the fixed cylinder of the lens barrel along the cylindrical surface of the fixed cylinder. The connector has a movable contact resiliently displaceable in the diametral direction of the cylinder. The movable contact is urged against a contact piece provided on the camera body upon completion of the mounting of the lens barrel to the camera body. The camera body is provided with an inclined surface for displacing the movable contact in the diametral direction against the resilient force during the mounting operation of the lens barrel to the camera body.

An interchangeable finder device of a single lens reflex camera has a finder optical system in which a focusing screen, a pentaprism and an eyepiece are fixed in a predetermined positional relation, a casing containing the optical system therein, and a mounting-dismounting device provided on the casing to mount the casing to the camera body. The finder device further has a sliding mechanism for supporting the finder optical system slidably in a direction perpendicular to the focus surface of the focusing screen relative to the mounting-dismounting mechanism so that the finder optical system can move in said perpendicular direction independently of the mounting-dismounting device when the casing is mounted to the camera body by means of the mounting-dismounting device.

An image formation apparatus includes a reception section, a function section, an image formation section and a power output device. The reception section is configured to be connected to a communication line over which image information and power are transmitted. The reception section receives the image information and the power transmitted over the communication line. The function section receives supply of the power received by the reception section, to function. The image formation section forms an image on a medium based on the image information received by the reception section or the function section. The power output device receives power supply from a commercial power supply. The power output device outputs power of a predetermined voltage to the image formation section.

A self-servo reference signal including a timing pattern and an oblique phase pattern is transferred in advance on a magnetic disk 1 by magnetic printing. A phase difference detection section 13 detects a phase difference between the two patterns to detect the position of a magnetic head 2. A burst signal generated by a record signal generation section 14 is recorded in a region of the magnetic disk 1 where no self-servo reference signal is recorded. A track pitch calculation section 11 determines a relationship between the reproduction output of the burst signal detected by a reproduction signal processing section 12 and the phase difference detected by the phase difference detection section 13, thus calculating an optimum data track pitch.
