ヘッドに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a type of thermal printer that uses transfer paper coated with heat-melting ink or heat-sublimable ink, or a type that uses thermal paper! This is related to the thermal head installed in '11.
従来、サーマルプリンタ装置に装着されているサーマル
ヘッドは、発熱抵抗体及びこの発熱抵抗体の両端部に設
けられている一対の電極部会てが一直線上にあるよう構
成されている。Conventionally, a thermal head mounted on a thermal printer device is configured such that a heating resistor and a pair of electrode portions provided at both ends of the heating resistor are aligned in a straight line.
この為、このようなサーマルプリンタ装置でプリントを
行なうと、発熱抵抗体の発熱シてよって形成されるドツ
トは、隣合うドツト間の濃度が上がらない欠点がある。For this reason, when printing is performed using such a thermal printer device, the dots formed by the heat generation of the heating resistor have the disadvantage that the density between adjacent dots cannot be increased.

The present invention provides a thermal head including a heat generating resistor connected between a first electrode section and the second electrode section in a row adjacent to the first electrode section.

上記のようにサーマルプリンタ装置のサーマルヘッドが
構成されていると、例えば所定の情報信に電流を流すと

のドツトが形成される。If the thermal head of the thermal printer device is configured as described above, for example, when a current is passed through a predetermined information signal, if the amount of current is small, a dot in the area shown by the central line (100) will be formed. Ru.
さらに、電流量が多く、高濃度部の印字は、第１図（ｂ

) Dots are formed in the area indicated by the dashed line in the middle.
′従って、高濃度部においては、隣合うドツトが重なり
、発熱体間の無印字部が無くなり、高濃度印字が可能に
なると共に平滑なプリントが行なわれる。'Therefore, in high-density areas, adjacent dots overlap and there are no non-print areas between heating elements, making it possible to print at high density and to achieve smooth printing.

有する。The thermal head according to the present invention includes: a plurality of first electrode parts; a plurality of second electrode parts provided approximately in the same row as the first electrode parts; Since the heating resistor is connected between the first electrode section and the second electrode section in the adjacent row, when printing using such a thermal head, it is difficult to print in a high concentration area. Cross-over of the printed dots occurs, increasing the printing density, and
The resulting printed image has features such as being smooth.
