A thermal printing apparatus has a housing divided into two sections, a main shell and a cover which are joined at one end to each other for opening and closing, for ease of the mounting, dismounting, and positioning of a thermal head with a pair of connectors without the use of any conventional tool. A platen is pivotably mounted to the cover. The thermal head includes a head side connector and a heating element mounted on one side of a rectangular base thereof for printing on labels. A head frame is provided having positioning members for determining the position of the thermal head to the platen when the housing is closed and positioning projections for coming into direct contact with four sides of the base to hold the thermal head in its position, and mounted to a base frame in the main shell. A circuit side connector is movably mounted to the head frame for fine positional adjustment to the head side connector.
