    Abstract: The present invention provides a camera system, which can simplify an ordering procedure. An IC memory comprising a contactless interface is mounted on a camera, or an image recording medium, such as memory card or film. In a case where a customer has carried the camera to a photo lab, image data is read out of the memory card or is acquired by reading the developed film, by an image data acquisition component. Moreover, individual information, order information, account information, and the like, are read out of the IC memory over wireless communication by a reader and writer and are affixed to the image data, whereupon the resulting image data is stored in a database.

    Abstract: A magnetic head device for reading and recording information from a magnetic recording section of a photographic film has a recording head and a playback head. The playback head and recording head are adjacently positioned by a head base plate. The head base plate rotatably supports the recording head and playback head as the head base plate rotates about a first rotation shaft and a second rotation shaft. The first rotation shaft extends in a direction of the film defined by movement of the film as film is wound onto a winding spool within a film cartridge. The second rotation shaft extends in a width direction of the film, perpendicular to the first rotation shaft. As a result the recording head and playback head make contact with the film to improve consistency of the playback and reading of information from the magnetic section of the film.

    Abstract: A camera using a film which has a magnetic storage part comprises a magnetic head which is arranged to read or write information out of or into the magnetic storage part of the film; and a release device for releasing a positional relation between the magnetic head and the film from an information reading or writing state in which the magnetic head reads or writes the information, until the film is wound around a spool or when the film is stopped.

  • Patent number: 5572269
    Abstract: A magnetic recording and/or reproducing head system particularly for use for writing and/or reading information on tracks in a magnetics-on-film (MOF) layer in the image area of photographic filmstrips, wherein the system provides for mounting of such magnetic heads on a suspension and translation system to move the magnetic heads from track to track of the MOF layer and longitudinally along a selected track. The filmstrip exhibits a lengthwise curvature of a predetermined sign and a cross-film curvature. The filmstrip is advanced to a stationary position in a curved transport path in the length dimension of the filmstrip, the curved transport path having a curvature radius of the same sign as the predetermined curvature sign of the filmstrip. The filmstrip edges are engaged in edge guides such that the transport path curvature and the edge guides negate cross-film curvature.

  • Patent number: 5568212
    Abstract: A camera includes a driving unit for rotating a film winding spool in a predetermined direction to wind the film or for rotating a spool in a loaded film patrone in a predetermined direction to rewind the film, a magnetic head pressing unit for pressing a magnetic head to a magnetic record section of the film interlocking rotation of the film winding or rewinding spool, an activating unit for activating the magnetic head pressing unit to retract from the film when an operation of the driving unit is stopped or when the spool is rotated in a direction opposite to the predetermined direction. The magnetic head is arranged in an inclined state against the film traveling direction such that a magnetic gap of the magnetic head contacts with the magnetic record section of the film at substantially right angle for a bent portion of the film by the contact of the magnetic head with the film.
