Heating head unit and heating head

摘要

A heating head with not so long heating elements to be connected, being adaptable to long and two-dimensional media. On one surface of a rectangular head substrate having long and short sides, a strip-like heating element is provided continuously from end to end of the substrate along the long side thereof. A pair of electrode connecting portions including the same material as that of the heating element and extending along the short sides of the substrate is provided at both ends of the heating element. A pair of electrodes is formed on one surface of the substrate between the heating element and a side edge of the long side at the electrode connecting portion side, so as to be partially overlapping with the electrode connecting portions, respectively, thereby effecting electrical connection, and a substrate temperature control means is provided.

1. A heating head unit comprising:
a rectangular head substrate having long sides and short sides, a strip-like heating element provided continuously on one surface of the head substrate from one end to another end of the head substrate along the long side of the head substrate, a pair of electrode connecting portions formed from the same material as that of the heating element where the heating element is bent and extends along the short side of the head substrate at both ends of the heating element to form the pair of electrode connecting portions, a pair of electrodes formed on the one surface of the head substrate between the strip-like heating element and the side edge of the long side of the head substrate at the side where the electrode connecting portions are provided, wherein the electrodes are electrically connected with each other while being partially brought into contact with each of the pair of electrode connecting portions, and a substrate temperature control means for controlling the substrate temperature by measuring the temperatures of the head substrate and a temperature measurement element.
