Abstract: A color recording method and device which is capable of color recording images on large-sized paper in which a first color is developed in direct heat sensitive paper by directly supplying heat energy of thermal heads to the direct heat sensitive paper. Furthermore, in order to transfer a color ink to the direct heat sensitive paper to thereby obtain a second color, the heat energy of the thermal heads is supplied to a plurality of ink ribbons which are coated with both a desensitizing material for controlling the coloring reaction of the direct heat sensitive paper and the desired colored inks.

Abstract: A printing method for performing enlargement printing of one continuous line by simultaneously shifting a plurality of printing heads by a shifting magnitude. The shifting magnitude of the printing heads is set to be greater than a shifting magnitude utilized in standard printing. Dividing points for shifting traces of each of the printing heads are set such that the shifting traces of adjacent printing heads partially overlap one another. Divided printing zones are established between the dividing points, and the printing timing of the printing heads is controlled for performing the enlargement printing of the one continuous line. Additionally, a printing method for performing reduction printing of one continuous line is performed by setting a shifting magnitude of the printing heads to be equal to that used in standard printing. Divided printing zones are established to be printed by at least two printing heads in a non-overlapping manner.

Abstract: A method and an apparatus for thermal recording and thermal transfer recording in a multicolor system. After performing the thermal recording, the thermal transfer recording is performed by overlaying a portion thermally recorded already. A thermal transfer donor sheet has a thermal transfer layer containing a desensitizer for suppressing a coloring reaction in the thermal recording layer of the thermal recording sheet. In performing multicolor recording by overlapping images of plural documents, after an image of a first document has been thermally recorded on a recording sheet, an image of a second document is recorded on the same recording sheet by thermal transfer recording. No color mixture occurs between colors thermally recorded and thermally transferred respectively and bright and clear color development can be obtained.

Abstract: A thermally sensitive recording head comprising, a two bases 2 moving with its attitude being kept along a guide shaft 5, an attachment 3 rotatably provided on the base 2 so that the base 2 extends to an right angle direction with the guide shaft 5 and contacts on or separates from a platen 8, and a heating head 4, which is rotatably provided on the attachment 3, and on front surface of which a heating body train is formed in a right angle direction with the guide shaft 5 and extends in opposite direction to an extending direction of the attachment 3 from the tip end of the attachment 3 to contact on or separate from the platen 8, whereby the attachment 3 and the heating head 4 are pressed on the thermally Sensitive paper placed on back-side of the platen 8. In this arrangement, a clear image can be obtained without generation of irregularity of photographic density because the heating head 4 presses the thermally sensitive papers while being kept always in parallel with the platen 8.

Abstract: In obtaining image data of an enlargement factor .alpha. by which the image data is enlarged and processed by multiplication with a non-integer number, the image data are firstly contracted and processed to a contraction factor .beta.=.alpha./.gamma., wherein .gamma. is an integer satisfying .alpha.<.gamma.. Then, the contraction-processed image data are subjected to pseudo half tone processing. Thereafter, the pseudo half tone processed image data are enlarged and processed by a factor .gamma. times. The contraction factor .beta. is selected as a value equal to or more than 50%. Thereby, even for an enlargement factor which requires multiplication by a non-integer number, visual image quality is upgraded, processing data amount is reduced and memory capacity is lowered, thus resulting in a lower cost.

Abstract: An image processing method of coloring an image with colors of well harmonized or matched group. Plural color groups, each including plural grouped colors and giving an individually different mental effect or impression, are stored in a memory, and a specified color group is selected from the stored plural color groups to color the image with colors included in the thus selected color group. Also provided is a system for the practice of the method described above.

Abstract: A microfiche reader is provided with pulse motors which move a microfiche card in X and Y direction so as to position a required frame image on the microfiche card in an optical projection path. Using the symbol AF for the maximum number of frames recordable on the microfiche card, the symbol AS for the maximum number of pulse signals required to move the microfiche card from the datum position to the limit position, and the symbol PF for the location number of a required frame, the address number NS of a required frame can be calculated according to the equationNS=PF.multidot.AS/AFThe number MS of pulse signals required to move the microfiche card from a present position to the required position is obtained from the difference between the address number NS of the required frame and the address number OS of the frame actually in the optical projection path. Pulse signals corresponding to the number MS are generated to control a pulse motor.

Abstract: Two microfiches carrying information recorded in different colors which can be detected independently of each other by means of color separation optical system are superposed in the direction of the optical axis of a projection optical system. The two kinds of information recorded in different colors on the two microfiches are separately displayed on a single or two display devices through color separation optical system such as color filters or a dichroic filter. When the two kinds of information are displayed on a single display device, the information is changed over by changing over the color separation system. When the two kinds of information are displayed on two display devices, they are displayed simultaneously.
