摘要： PURPOSE: To lessen density irregularities in a direction of heat-generating elements and in a transfer direction far recording papers by setting the length of the heat generating element of a heat-sensitive recording head in a direction orthogonal to arm arranging direction of the elements to be 1.5 times or more a predetermined pitch of a recording medium transfer means. CONSTITUTION: A heat-generating element 35 corresponding to one dot is formed of a resistance thin film of a length of 1 held between a common electrode 37 and an individual electrode 38 both formed of a conductive thin film 34. One heat-generating element 35 is separated from tone adjacent heat,-generating element by an inter slit 39. At tone same time, the }neat-generating element 35 is separated to two partial heat-generating elements 35a, 35b of the same width Wo in parallel by a central slit 40 set at the center in a widthwise direction of tone heat-generating element. A width W2 of the inter slit 39 is equal to a width W1 of the central slit 40, i.e., 25μm or smaller. This width is essential so as root to generate white stripes when an image is recorded. The length of the heat-generating element is set to be not smaller than 1.5 times a paper transfer pitch, so that density irregularities in the transfer direction of papers can be restricted.

摘要： PURPOSE:To make it possible to record stably with a high picture quality and also make the maintenance operation easier by a method wherein a feculence adhering quantity is assumed by measuring the total contact moving quantity of a heating element and an intermediate recording medium, and that is informed to an adhered feculence removing unit, and the feculence is removed by causing contact sliding between the heating element and the surface of a recording medium moving unit. CONSTITUTION:By setting a limit to the quantity of ink papers which can be contained in an ink paper cassette 3, after recording of a prescribed number of papers have been performed, the ink papers in the cassette are totally consumed without fail. Therefore, this is used as a feculence adhering quantity assuming means by a detection of the final end of ink papers by the rotation stop of an FG pattern unit 314. When deciding that the ink papers in the ink paper cassette 3 have been totally consumed, a controller stops the recording motion and functions as a decision informing unit. Then, a platen drum 1 is rotated under a condition where this thermal head 2 is in contact with the platen drum 1, and the vicinity of a heating element 210 in the thermal head 2 and the surface of the platen drum 1 are made to slide and cleaned. By this method, a stable thermal transfer recording with high quality can be performed.

摘要： PURPOSE:To enable the printing to a rough surfaced paper by making it possible to sufficiently and closely contact a head with the rough surfaced paper having large unevenness, by a method wherein the cross-sectional shape of a glaze layer region is formed in the longitudinal direction thereof so that the area thereof corresponding to the max. temp. heat generating part of a heat generating resistor comes to a recessed part. CONSTITUTION:The cross-sectional shape of the glaze layer 2 formed on an insulating substrate 1 comprising alumina ceramic is formed so as to have two projections between which a central recessed part is formed. The glaze layer having this shape can be formed by a method for molding a glaze layer after usual printing and baking by etching or a method for fusing and bonding two partial glaze rows after printing and baking. The resistor layer 6 between electrode layers 4, 4' comes to a heat generating resistor. The contact pressure of the heat generating part and recording paper becomes large at the projected parts and the close contact of both of them is improved because the protruded parts of rough surfaced paper having large unevenness are collapsed to a certain degree and the projections of the head becomes easy to penetrate into the recessed parts.

摘要： PURPOSE:To enable different printing forms to be selected by an area gradation method to obtain multi-graduation by allowing continuity to be introduced only between desired electrodes using a positive characteristic thermistor which electric resistance value rapidly increases at higher than a certain temperature to a heating resistor. CONSTITUTION:The tips of plural signal electrodes 15, 16 are positioned along both edges of a positive characteristic thermister (PTC) which electric resistance value rapidly increases at higher than a certain temperature to a heating resistor 17. Then if a printing voltage is, for example, applied to signal electrodes 15c, 16a which allow continuity according to information, an electric current concentrates in the part 18 of the heating resistor 17 sandwiched between both electrodes and only said part is heated at high temperature. Thus many different heating dot forms can be selected. In addition, the area of the heating element can be varied by controlling the bulk width of a voltage to be applied and subsequently, super fine printing is performed in multi-gradation expression.

摘要： PURPOSE: To record stably intermediate density information by changing a sub-scan interval and the number of times of exothermic recording in accordance with the recorded density and reducing the density dispersion in a dot area.
CONSTITUTION: Picture data of one line is transmitted to a line memory 9 from a picture information soruce 8 and stored in it. Then the gradation number of the density of an exothermic element in the data from the memory 9 is discriminated by a gradation divider 10 and is transmitted as data to a heat recording head 4 and a conductive time controller 28. In accordance with the presence or absence of the conduction at every exothermic element 4 from the divider 10, the head 4 causes each element to be conducted and heated with the aid of a conduction time signal at every exothermic clement from a conduction time control circuit 11, and carries out recording. When the gradiation number of the density is minimal, the conductive time controller 28 acts so as to function a loop constituted of the circuit 11, sub-scan controller 12 and controller 28, whereby the original sub-scan interval is further divided to execute the sub-scan and the exothermic element is conducted and heated by the number of times in accordance with the given gradation number.
