Abstract
In a thermal recording apparatus using a plurality of thermal heads supported by a head supporting means including a head supporting mechanism and a head pressing mechanism. The head supporting means includes single supporting units provided for correspondingly respectively supporting the thermal heads. Each of the single supporting units has a pair of hook-shaped members fixed to corresponding one of the thermal heads at two places of the rear surface thereof, and has a head supporting member having a pair of side end portions corresponding to the pair of hook-shaped members and a plane portion formed between the pair of side end portions and fixed to a rotatable pillar-shaped member. The head supporting member is engaged at its side end portions with the respective hook-shaped members so as to be movable in the vertical and rotational directions. The head pressing mechanism has a pair of compression springs for pressing the rear surface of each of the thermal head at a symmetric position, a pair of movable members for correspondingly respectively keeping the thermal heads through the compression springs, and a common movable member for arranging the pair of movable members on one…
