摘要： A printer having a thermal head disposed such that when heater elements are in contact with a platen, the following formulas are satisfied: H1≦H≦Hmax; Hmax=(H1+H2)=L tan(θ1+θ3); and θ′=(θ2−θ1)=(3°±1°). Length L is between a first line perpendicular to a top-substrate-surface and extending through a contact point between the heater elements and the platen, and a second line perpendicular to the top-substrate-surface and extending through a peak of a sealing member; height H is from the top-substrate-surface to the peak; height H1 is from the top-substrate-surface to a tangent between the platen and the heater elements; height H2 is from the tangent to a conveying path of a recording medium; angle θ1 is between the tangent and the top-substrate-surface; θ2 denotes a slope angle of a projection from the tangent; angle θ3 is between the tangent and the conveying path; and θ′ denotes a head-returning angle.

摘要： A heat-dissipating member includes a heat-dissipating section which is plate-shaped and which is attachable to a heat source directly or indirectly and also includes a plurality of heat-dissipating projections extending from the heat-dissipating section. The heat-dissipating projections are formed by louvering the heat-dissipating section so as to have predetermined heights. The heat-dissipating projections are arranged in increasing order of height in the direction from one end of the heat-dissipating section to an end of the heat-dissipating section that is opposed to the one end. A thermal head includes a plurality of heating elements arranged thereon and a head mount attached to the above heat-dissipating member directly or indirectly.

摘要： A line thermal printer includes a platen roller and a line thermal head including a plurality of heating elements. The heating elements are disposed to face the entire area of a recording sheet in a width direction of the recording sheet and selectively generate heat. The recording sheet is interposed between the platen roller and the line thermal head. The line thermal printer performs printing at the interposed position on the recording sheet by the selective generation of heat of the heating elements while the recording sheet is moved. The line thermal printer includes a foreign material blocking member. The foreign material blocking member is disposed upstream of the interposed position to come in contact with an upper surface of the recording sheet, and prevents foreign materials, which are placed on the upper surface of the recording sheet, from being moved toward the interposed position.
