A film image input system is disclosed which can use a film cartridge constructed in such a manner that it requires a small space for storing a developed still photo film and also can protect the film against dust and damage, and also which allows the film cartridge to be mounted into a cartridge mounting part very simply and positively. The film image input system,is arranged such that it reproduces the image of the developed still photo film,on a video monitor,. The system uses a film cartridge,which comprises a cartridge main body having an outlet opening,for sending out the film,in the longitudinal direction thereof, a single spool which fixes one end of the film,in the longitudinal direction thereof and round which the whole length of the film,can be wound, and support means for supporting the spool in such a manner that it can be rotated in both directions. The film image input system includes film supply means,which is engageable with the spool of the film cartridge,to rotationally drive the spool in a direction to send out the film,from the cartridge main body and in a direction to rewind the film back into the cartridge main body. Due to this, the film image can be reproduced by one touch on the video monitor

A film image input system is disclosed which can use a film cartridge constructed in such a manner that it requires a small space for storing a developed still photo film and also can protect the film against dust and damage, and also which allows the film cartridge to be mounted into a cartridge mounting part very simply and positively. The film image input system 1 is arranged such that it reproduces the image of the developed still photo film 2 on a video monitor 18. The system uses a film cartridge 6 which comprises a cartridge main body having an outlet opening 7 for sending out the film 2 in the longitudinal direction thereof, a single spool which fixes one end of the film 2 in the longitudinal direction thereof and round which the whole length of the film 2 can be wound, and support means for supporting the spool in such a manner that it can be rotated in both directions. The film image input system includes film supply means 13 which is engageable with the spool of the film cartridge 6 to rotationally drive the spool in a direction to send out the film 2 from the cartridge main body and in a direction to rewind the film back into the cartridge main body. Due to this, the film image can be reproduced by one touch on the video monitor 18.

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. The base of the photo film used in the film image input method is poly-ethylene-naphthalate, and more preferably, is heat treated at more than 50.degree. C. and less than the glass transition temperature for 0.1-1500 hours.

Film image input method

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.

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. The black pixel recording may be performed simultaneously with recording a first color frame of the image in a first of the three thermosensitive recording layers which is colored first by applying heat energy of the lowest range when the three thermosensitive recording layers are sequentially developed for recording pixels other than the black pixels.

A device for loading or unloading a magnetic disc pack applicable to a magnetic recorder or reproducer in an electronic camera system wherein a subject is electronically still-photographed and recorded in a rotating magnetic disc, and the reproducing of an image is carried out by a television system or a printer. A lid is openably supported by a main body of the magnetic recorder or reproducer. An inner bucket is pivotally supported on the main body or the lid, having a U-shaped configuration in which the magnetic disc pack incorporating a magnetic disc is received and is capable of being separated from the lid or the main body to form an opening, into which the magnetic disc pack is inserted, when the lid is opened. An engageable hole is formed in the end face of the inner bucket of the device for loading or unloading the magnetic disc pack. The engaging member is located at this engageable hole in a manner to be projectable into the engageable hole or retractable therefrom. When the lid is opened, if the magnetic disc pack is inserted into the inner bucket, then this engaging member projects into the engageable hole to retain the magnetic disc pack in the inner bucket after the inner bucket is received in the lid by the closing operation of the lid, the engaging member is retracted from the engageable hole to release the restraint of the magnetic disc pack.

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. When the door is locked with the body of the apparatus, the control plate is correctly positioned in a predetermined position to give access to the magnetic sheet.
