摘要： PURPOSE:To improve the contact characteristic of a platen, to widen a recording printing width and to perform high-speed, high-quality printing, by integrally bonding a pair of thermal heads each formed by providing a membrane layer composed of polycrystalline silicon on a substrate and forming a heat generating resistor and a drive circuit part on the same substrate and performing thermal recording by the side surface of the integrated thermal head on the heat generating resistor forming side thereof. CONSTITUTION:A thermal head is constituted by integrally bonding a pair of thermal head chips 10, 10 each constituted by forming a heat generating resistor 2 and a drive circuit part 3 on a substrate through an insulating adhesive 11 so as to allow the heat generating resistors 2, 2 to oppose to each other. The substrate 1 is polished in a curved surface shape on the side of the side end surface 1a thereof and the end surface of the adhesive 11 facing to the side end surface 1a is used as a slide surface in thermal recording and thermal recording paper 12 is pressed and held by a platen 13 to perform thermal recording. The active layer 3c constituting a membrane transistor of the heat generating resistor 2 and the drive circuit part 3 is constituted of a polycrystalline silicon membrane. The width (l) of the slide surface 16 of the thermal head can be expanded to a large extent and, when predetermined high density printing is desired to be obtained, high-speed printing is possible.

摘要： PURPOSE:To ensure that the heating value of a heat generating resistor part is greater on the higher side of an inclined recording surface, the surface temperature of the recording surface can be set substantially uniform, the shape of developed color dots on a thermal recording paper can be uniformized and printing quality can be enhanced, by setting the resistance of the heat generating resistor part to be gradually higher in the direction of increasing height of the inclined recording surface. CONSTITUTION:The rear side 1b of a substrate 1 is slantly ground so that it is sloped down toward a front edge and the thickness thereof on a heat generating part 2A is a predetermined value, thereby providing a recording surface 1b1. The heat generating part 2A is located on the front edge side of the substrate 1 at a position where the thickness of the substrate 1 is relatively small due to the presence of the inclination of the back side 1b, so that favorable heat transmission to the recording surface 1b1 is obtained. In addition, the resistance of the part 2A is set to be gradually higher toward the higher side of the inclined recording surface 1b1, so that the heating value is increased in the same direction. Therefore, though the recording surface 1b1 slantly corresponds to the heat generating part 2A, it is substantially uniformly heated, dots can be printed on a thermal recording paper with a fixed developed color density without increasing the electric power inputted to the part 2A, and power efficiency is enhanced.

摘要： PURPOSE:To obtain good image quality generating no blotting of a picture element at the time of high-density printing and not interfered by the density of the adjacent picture element by eliminating the dropouts of picture elements at the time of low-density printing, by providing an auxiliary heat generator element narrower than each main heat generator element between a plurality of main heat generator elements. CONSTITUTION:Because a predetermined drive current is supplied to auxiliary heat generator elements 8, 8 at the time of low-density printing and the auxiliary heat generators 8, 8 generate heat, the temp. characteristic of thermal recording paper in the horizontal direction X comes to the state shown by A and predetermined temp. is kept even at the part corresponding to the space between main heat generator elements 2a, 2b, that is at the space between picture elements and no dropout is generated. At the time of high-density printing, no drive current is supplied to the auxiliary heat generator elements 8, 8 and, because said auxiliary heat generator elements 8, 8 have extremely good heat conductivity, the heat between the main heat generator elements 2a, 2b, that is, between the picture elements is dissipated through said auxiliary heat generator elements 8, 8. Then the temp. characteristic of the thermal recording paper in the horizontal direction X is shown by C with no interference acting between the adjacent main heat generator elements 2a, 2b and the blotting of the picture element is improved without being interfered by the density between adjacent picture elements. Accordingly, printing high quality is obtained.

摘要： PURPOSE:To obtain a thin film thermal head superior in productivity, mass production properties, and production cost, by forming a recording portion on a drive circuit portion through an insulating layer. CONSTITUTION:A drive element portion 11 and a control element portion 21 having a logic circuit are made of a thin film transistor and formed on a planar face of a substrate 1. Moreover, on the drive transistor 11, a heating resistor 25 is formed through an insulating layer 10. In the drive transistor 11, a semiconductor thin film 2 of a polycrystalline silicon thin film is provided with low- resistance n-type areas 2a, 2b doped with a predetermined n-type impurity at the both ends thereof. These n-type areas 2a, 2b respectively form a drain area 3 and source area 4. In the acting condition, the portion between the drain area 3 and the source area 4 in the semiconductor thin film 2 has a channel, thus making an activated layer 2c. In this manner, a large number of head chips can be formed together on the single substrate, which enables the improvement in a productivity and a mass production properties and the remarkable reduction of the production cost.
