Title:
THERMAL PRINT HEAD AND THERMAL PRINTER
Document Type and Number:
WIPO Patent Application WO/2015/111520
Kind Code:
A1
Abstract:
This thermal print head is provided with a base material, an electrode layer formed on the base material, and a resistor layer formed on the base material. The electrode layer includes a common electrode, and a plurality of individual electrodes. The resistor layer includes a plurality of heat-generating parts arrayed in the main scanning direction. Each of the plurality of heat generating parts has a first heat-generating element and a second heat-generating element which are spaced apart from one another. The first heat-generating element and the second heat-generating element respectively have electrical continuity with the common electrode, and with a given individual electrode among the plurality of individual electrodes.
