Abstract: A photo film, which is hard and has a little winding peculiarity and which is excellent in dynamic intensity, is used, whereby film feeding problems, which easily occur when a line sensor is used, are reduced. A long roll of a developed photo film for still photography, which is loaded between a feeding side and a winding side, is fed at a constant speed between the feeding side and the winding side, so that the image data are taken in through a line sensor. Before taking in the image data of the desired frame, first, a taking environment such as a brightness and a white balance of every frame is detected during the first feeding of the photo film. And, when one frame is reproduced, the image data of the desired frame are taken in through the line sensor during the second feeding of the photo film, and further, an exposure, a white balance and the like are adjusted in accordance with the detected taking environment of said frame when the image data are taken in.

Abstract: A photographic film is prevented from being damaged by dust adhering thereto due to static electricity generated in the photographic film during the feeding thereof. A brush for removing the static electricity as being a conductive member is brought into contact with a portion of the photographic film other than a photographic exposure surface. Furthermore, the brush is grounded through a line to a casing of a film image input system, which has electric potential 0. With this arrangement, the static electricity generated in the photographic film during the feeding thereof can be removed through the line from the brush for removing the static electricity. Thus, the static electricity is not accumulated in the photographic film and the dust does not adhere to the photographic film. Therefore, the photographic film can be prevented from being damaged by the dust.

Abstract: A direct color thermal printing method records a full-color image containing black characters on a thermosensitive color recording medium having three laminated thermosensitive recording layers. Three color components of each pixel are sequentially read out from three color frame memories. If all of the three color components of a pixel correspond to the maximum densities, that pixel is determined to be printed in black, and is stored as black pixel data in a black line buffer memory. When recording the black pixels, a thermal head is driven to apply a predetermined maximum amount of head energy to the thermosensitive color recording medium, for simultaneously coloring the three thermosensitive recording layers in accordance with the black pixel data.

Abstract: A stepping motor for use in a magnetic disc reproducing apparatus for causing radial scanning movement of a magnetic head relative to a magnetic disc having many picture information recorded on concentric tracks, comprises a casing, a rotor, stator coils to which current is supplied according to a sequence of phase cycles, and a rotor positions detector which includes two electrically-connected contactors mounted on the rotor, and an annular conductor pattern and an arcuate conductor pattern provided in the casing to make continuous and temporary contact with the respective contactors. The arcuate conductor pattern covers a range corresponding to an angle through which the rotor rotates in a predetermined one cycle among the phase cycles of current supply to the coils.

Abstract: A device for loading or unloading a magnetic disc pack includes a lid pivotally supported by a main body of the magnetic recorder or reproducer; and an inner cassette holder pivotally supported on the main body or the lid, having a configuration in which the magnetic disc pack incorporating a magnetic disc can be received and which is capable of being separated from the lid or the main body to expose an opening, into which the magnetic disc pack is inserted when the lid is opened, and a push member for pushing the center core of the magnetic disc toward the rotary drive shaft. By the closing operation of the lid, the cassette holder is guided to a position where the center core of the magnetic disc can be coupled onto the rotary drive shaft and the push member is guided through a position where the push member pushes the center core of the magnetic disc and to a position where the push member is out of contact with the center core of the magnetic disc.

Abstract: A magnetic recording/reproducing apparatus using a magnetic sheet as a recording medium includes a pack holder receiving a magnetic sheet pack containing the magnetic sheet therein. This pack holder is integrally firmly secured to the inner side of a door to be opened and closed at a time when the magnetic sheet pack is loaded and unloaded. In its opened state, only a gate portion formed in the door in such a manner as to be in communication with the pack holder is exposed. When the door is closed after the magnetic sheet pack is inserted from this gate portion to load it in the pack holder, an oscillating lever is oscillated in cooperation with the movement of the door. At one end of the oscillating lever, a control plate adapted to maintain a satisfactory head contact of the magnetic head with respect to the magnetic sheet is axially attached. When the oscillating lever is oscillated as mentioned above, the control plate enters into the pack holder.
