Abstract: A thermal printer is used with a thermosensitive recording sheet, and records an image on the recording sheet. A predetermined discernment code is provided for the recording sheet. A code reader inputs the predetermined discernment code. A system control block stores reference code, and checks the predetermined discernment code with reference to the reference code to judge whether the recording sheet is acceptable or unacceptable. If the recording sheet is unacceptable, printing operation is inhibited and/or an alarm signal is generated.

Abstract: A recording sheet roll includes a winding core, about which a continuous recording sheet is wound. An information code is disposed on a surface of the winding core in an arc shape, and includes plural data indicia DM arranged serially. A start indicia SM is disposed between a beginning and end of a train of the plural data indicia DM, and has a size greater than each of the data indicia DM. A code reading device for the recording sheet roll includes a supply roller for rotating the recording sheet roll at a constant peripheral speed in a winding direction of the recording sheet. A reading photo sensor reads the plural data indicia DM and the start indicia SM. A timer at a CPU measures passage time during which plural indicia in the information code pass the reading photo sensor while the recording sheet roll makes one rotation, and thereafter rotates for a predetermined time T1.

Abstract: Frames images in all frames on developed photographic film are read first, and an index image is made of a plurality of frames to be displayed on a TV monitor. Then, one of a plurality of regeneration modes is designated. When regeneration in the designated regeneration mode is commanded, frame images on the photographic film are read on a frame-by-frame basis. The read frame images are regenerated on the TV monitor on a frame-by-frame basis in the designated regeneration mode. Thereby, a regeneration mode suitable for the film can be selected among a plurality of regeneration modes, while the frame images on a roll of film are confirmed by means of an index image displayed during regeneration mode selection.

Abstract: A magnetic track on a roll of photographic film is divided into a leader track on the forward end part of the film and a frame track corresponding to each frame, which is located after the ladder part. A manufacturer identification code including the manufacturer code which is peculiar to the manufacturer, a function selection code indicating a specific function and the like is recorded in the leader track. In each frame track, magnetic information is stored which is determined by the manufacturer identification code, the function selection code and the like. Furthermore, a film image on a roll of developed film is read out, then an image of one or plural frames is displayed on a TV monitor. Users enter the above described magnetic information while looking at a display screen of the TV monitor so that magnetic information relating to a printing can be recorded easily and without mistakes.

Abstract: An index image which shows plural frames on a film strip within a film cartridge and/or a film image in one frame are displayed on a display. Information relating to automatic regeneration or automatic printing for regenerating plural film images on the film sequentially and automatically is entered by an user who is looking at the display. The entered automatic regeneration information or automatic printing information are recorded in a record medium which corresponds to the film cartridge. When the automatic regeneration or automatic printing is performed, the film player reads out the automatic regeneration information or the automatic printing information from the record medium, and automatically regenerates or prints the plural film images on the film strip in accordance with the readout automatic regeneration information or automatic printing information.

Abstract: When a volume of magnetic information to be recorded in a film exceeds a recording capacity of the film, a part or all of the magnetic information is recorded in an outer record medium. At this time, ID information which identifies the outer record medium is recorded in a leader track on the film, so that the film can correspond to the outer record medium. An ID number, for example, is used as the ID information. When the magnetic information is read out from the film, the ID information which identifies the outer record medium is read out at first. Then, it is judged whether the outer record medium is used or not. If the outer record medium is used, the magnetic information is read out from the outer record medium, and various kinds of processing are carried out in accordance with the readout magnetic information and the magnetic information which is recorded on the film.

Abstract: At first, the film in a film cartridge is wound up. Next, the film is rewound into the film cartridge, and a perforation indicating a reference position of each frame is detected. Then, predetermined information corresponding to the detected perforation is recorded in the magnetic layer. In another embodiment, when the perforation provided closest to the forward end of the film is detected, the film is rewound a required length. Then the magnetic recording is performed after the rewinding is completed. In another embodiment, two detectors for detecting a perforation is provided. One detector is apart from the other by a multiple of a distance between frames. Every time one detector detects a perforation, magnetic recording/regenerating is carried out.

Abstract: Upon detecting a freeze button depressed, while a tape is played back on a video tape player, a system control of a video printer supplies the tape player with a control signal to stop the playback operation on the tape. In the state in which the playback operation on the tape is stopped, a subsequent depression of the freeze button causes the system control to send out a control signal to instruct the tape player to initiate the playback operation on the tape, and a storing of picture signals in a frame memory causes the system control to send out the control signal to instruct the tape player to stop the playback operation.

Abstract: In a video printer, to delete a frame of video data stored in a frame memory, mute data is written in the frame memory over previously written video data by operating a memory delete key. Thereby, a mute image is displayed on a monitor. To delete one of a matrix of sub-frames of a multi-frame image, the sub-frame to be deleted is designated prior to operating the memory delete key, so that mute data is written in a corresponding location of the frame memory. Thereby, an image containing a blank in at least one sub-frame may be printed out.

Abstract: A video printer is supplied with image information, which represents a halftone image having an aspect ratio of 4/3. A rotationally converting section in IC converts the image information so that orientation of the image makes one fourth rotation. A size reducing section in IC processes the image information to reduce a size of the image. A thermal recording head is supplied with the image information after the reduction and the rotational conversion, and records the image on a color thermosensitive recording sheet, which has an aspect ratio of 4/3. The image is recorded in an upper half of the recording sheet. A phrase memory stores phrase information. A synthesizing circuit combines the phrase information with the image information after the reduction and the rotational conversion. The phrase is preferably recorded in a lower half of the recording sheet and outside the image.

Abstract: A method for initializing a magneto-optial disk comprises the steps of positioning at least one magneto-optical disk in a coil, wherein the length of said coil is shorter than the diameter thereof, so that the direction of the thickness of the magneto-optical disk coincides with the axial direction of the coil, and applying a predetermined pulsed current to the coil in order to generate an instantaneous magnetic field. The pulsed current is generated by a device comprising a charging circuit which charges a capacitor, and a discharging circuit, which applies a current to the coil, said current being generated by discharging the capacitor. A lifter supports the magneto-optical disk and conveys the magneto-optical disk in the direction of the thickness thereof in order to position it in the coil.

Abstract: Patterns to be drawn by a controlled electron beam producing system or a like system, as on a mask for integrated circuits, are classified into nonrepetitive and repetitive patterns. Each repetitive pattern is specified by those coordinates of an elementary pattern and those displacement and numbers of repetition of the elementary pattern which are stored in a data file as are the cases with coordinates of nonrepetitive patterns. In addition to a first register group for each of nonrepetitive patterns, a device for controlling production of the beam comprises a second register group for the data supplied thereto by accessing the data file only once for each repetitive pattern. A sequence controller repeatedly reads the coordinates of the elementary pattern from the register group, with the coordinates varied according to the displacements also read therefrom a plurality of times determined by those numbers of repetition which are also read therefrom.
