摘要： A thick film type thermal head for thermally perforating a stencil material in an imagewise pattern to make a stencil is moved along the stencil material in a sub-scanning direction while energizing a plurality of heater elements arranged in an array extending in a main scanning direction. The thermal head includes an electric heater strip extending in the main scanning direction direction, and a plurality of first and second electrodes which are alternately disposed spaced from each other in the main scanning direction and extend across the heater strip in contact with the electrodes. The parts of the heater strip between adjacent first and second electrodes form the heater elements. An electrical insulating layer is disposed between the first and second electrodes and the heater strip at least on one side of the heater strip so that the width of the electrical contact area between the first and second electrodes and the heater strip becomes smaller than the width of the heater strip.

摘要： A master making device includes a thermal head with heat generating elements and a platen roller. While the head and platen roller convey a thermosensitive medium in a subscanning direction perpendicular to a main scanning direction, the heat generating elements selectively generate heat in order to perforate the medium in accordance with an image signal. The head includes a stepped portion formed at a medium outlet side in the subscanning direction. The edges of the heat generating elements adjoining the medium outside side are located at a distance of 0.018 mm to 0.5 mm from the end of the stepped portion adjoining the above edges. It is not necessary to position the head with respect to an effective nip between it and the platen roller by a troublesome procedure. Further, the distance over which the perforated medium is conveyed is reduced to obviate the reduction or contraction of an image ascribable to the sticking of the medium to the head.
摘要翻译：主制造装置包括具有发热元件的热敏头和压纸辊。当头部和压纸辊在垂直于主扫描方向的副扫描方向上传送热敏介质时，发热元件选择性地产生热量，以便根据图像信号对介质进行穿孔。头包括形成在副扫描方向上的介质出口侧的台阶部分。与介质外侧相邻的发热元件的边缘位于与上述边缘相邻的台阶部分的端部0.018mm至0.5mm的距离处。通过麻烦的过程，不需要相对于其与压纸辊之间的有效压区来定位头部。此外，减少了穿孔介质被输送的距离，以消除由于介质粘附到头部而引起的图像的减少或收缩。

摘要： A thermal head including a protection layer having mutually opposed first and second surfaces, said first surface having a flat or protruded printing surface which is brought into contact with a heat sensitive record medium, a heat generating section including resistors and electrodes connected to the electrodes and provided on said second surface of the protection layer, and a reinforcing member made of a low melting pint glass and provided on a side of the heat generating section remote from the protection layer. The reinforcing member improves a mechanical strength of the thermal head. The reinforcing member made of a glass also serves as a heat storage member, and thus a thermal property of the thermal head is improved. The reinforcing member may be formed by an aggregate of ceramic particles. The reinforcing member may contain a heat storage layer made of a low melting point glass and a heat conduction layer provided on the heat storage layer.

摘要： A thermal head includes a heat radiating plate and an electrical insulating substrate which is provided with a plurality of resistance heater elements arranged in a direction over a predetermined length and a plurality of electrodes for energizing the resistance heater and is integrated with the heat radiating plate. The substrate is smaller than the heat radiating plate in coefficient of thermal expansion and is fixed to the heat radiating plate at a temperature higher than the normal working temperature range of the thermal head. In the normal working temperature range of the thermal head, the thermal head is convex toward the resistance heater in a cross-section taken along a line parallel to the direction in which the resistance heater elements are arranged due to the difference in coefficient of thermal expansion between the heat radiating plate and the substrate.
