Abstract
A printer having a thermal head disposed such that when heater elements are in contact with a platen, the following formulas are satisfied: H≦H≦H; H=(H+H)=L tan(θ); and θ'=(θ)=(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 His from the top-substrate-surface to a tangent between the platen and the heater elements; height His from the tangent to a conveying path of a recording medium; angle θis between the tangent and the top-substrate-surface; θdenotes a slope angle of a projection from the tangent; angle θis between the tangent and the conveying path; and θ′ denotes a head-returning angle.
