Embodiment Construction

[0027] Hereinafter, an embodiment of a thermal printhead as an embodiment of the recording head of the present invention will be described with reference to the drawings.

[0028] Such as figure 1 and figure 2 As shown, the thermal head X1 of this embodiment is configured to include a head base 10 , a driver IC 20 , a wiring member 30 , and a radiator 40 . It should be noted that, for the convenience of explanation, in figure 2 In (a), illustration of the driver IC 20, the wiring member 30, the radiator 40, and the later-described protective layer 15 is omitted, and in figure 2 In (b), illustration of the radiator 40 is omitted.

[0029] The head base 10 has a head substrate (substrate) 11 , a glaze layer 12 , a resistive layer 13 , and electrode wiring 14 sequentially formed on the head substrate 11 . Moreover, the glaze layer 12 has the flat base part 12a, and the protrusion part 12b which protrudes from the upper surface of this base part 12a. In the region of the r...

Abstract

The invention provides a recording head and a recording device having the recording head, which can reduce the uneven heating temperature of each heating element in a heating element row. A recording head according to an embodiment of the present invention has: a radiator (40); a printhead base (10), which has a substrate (11) arranged on the radiator (40) and a plurality of substrates (11) arranged on the substrate (11). A heating element column composed of heating elements (13a); a bonding layer (17), which is arranged between the radiator (40) and the substrate (11) and bonds the radiator (40) and the substrate (11); a plurality of spacer particles (19) arranged in the bonding layer (17) and in contact with both the radiator (40) and the substrate (11). The bonding layer (17) has a first region (S1) located directly below the heat generating element row, and a second region (S2) extending parallel to the first region (S1). Spacer particles (19) are arranged in the second area (S2).

Description

technical field [0001] The present invention relates to a recording head and a recording device having the recording head. Background technique [0002] Conventionally, various recording heads such as thermal print heads have been proposed as image printing devices such as facsimile machines and image printers. For example, for the thermal printhead (thermal printer head) described in Patent Document 1, a plurality of heating elements are arranged in a row on the upper surface of the support substrate, and the above-mentioned support substrate is bonded via a heat-dissipating adhesive material and a double-sided substrate. The adhesive tape is arranged on the heat sink. In addition, the layer made of the heat-dissipating binder (hereinafter referred to as binder layer) contains a powdery body made of alumina ceramics whose particle diameter is substantially the same as the thickness of the binder layer.
