Claims (1)

[Scope of utility model registration request] a thermal head that selectively generates heat from a plurality of heating elements according to recorded image information; a platen equipped with elasticity disposed opposite to the thermal head;
A biasing means for bringing the thermal head and the platen into pressure contact is provided, and a recording sheet and a recording medium are inserted in a stacked manner between the thermal head and the platen, and information from the heating element is recorded on the recording sheet. In the thermal recording device, at least one of the thermal head and the platen is curved along its length, so that the deflection locus of the platen that occurs when the thermal head is in pressure contact with the thermal head and the recording surface of the thermal head are aligned. A thermal recording device characterized in that a reference line along which the device is followed substantially coincides with the reference line.
