    摘要: A magneto-optical disc recording apparatus arranged such that the magneto-optical disc is recorded by irradiating the magneto-optical disc with a recording light beam from an optical pickup head device under the condition that the optical pickup head device is applied with an external magnetic field by external magnetic field generating means. In this magneto-optical disc recording apparatus, a spacer sheet is located on the magneto-optical disc, whereby the external magnetic field is applied to the magneto-optical disc under the condition that the external magnetic field generating means is brought in contact with the spacer sheet.

    摘要: A thermal recording head is provided with a driving system wherein higher printing speeds may be obtained. Particularly, in the case where the image to be printed by a divided block of elements is totally black, all common driving terminals corresponding to the block are selected for simultaneous recording.

    摘要: A thermo-sensitive recording apparatus individually controls the energization level of each of a plurality of heater elements formed on a substrate and constituting a thermal print head. In generating each energization level, the present and previous status of an individual heater element and selected neighboring elements are taken into consideration. Other factors combined in a selectively weighted manner include the latent heat of the individual heater element and its neighboring heater elements, the resistance of the heater element, the percentage of heater elements to be activated during the printing of a line, and the temperature of the substrate.

    摘要: A transfer type heat-sensitive recording medium having a porous base impregnated with a colorless color former. A layer of thermally melting ink is formed on one side of the porous base. The first layer is brought into contact with a recording sheet. A layer of thermally melting wax containing a color developer is formed on the opposite side of said porous base and selectively heated according to a video signal. The wax melts and permeates into the porous base to allow the color developer to color on reaction with the colorless color former. The wax layer is further heated by thermal irradiating so that the ink of the ink layer is molten in correspondence to the coloring.

    摘要: A color copying machine includes a device separating the image information from each area of the original into colors corresponding to predetermined recording colors to thereby form corresponding video signals. A preferential selection circuit converts each video signal into a 2-level signal and performs an arithmetic operation on each 2-level signal to thereby key the image information from each area of the original to one of the recording colors or white. Black is selected as the recording color if a chromatic color competes with black in the same area.

    摘要: A thermal recording method which prevents recording density defects includes preheating the heating elements of the thermal recording head during a time when printing is not carried out. Particularly, the head may be preheated during times when a line is not printed, as between adjacent character lines of a printed or typed document, to prevent recording density deterioration of the next printed line.

    摘要: A thermosensitive copying machine can selectively use either manually or automatically supplied paper, has a pivotable roller and brake mechanism for minimizing wrinkles in the ink donor sheet, supplies the copy paper and donor sheet over paths which differ except at the recording station, and has a separating guide member for peeling the copied paper away from the donor sheet. The donor sheet transport mechanism is enabled only when necessary for a recording operation.
