ABSTRACT:
A press device in a color video pointer which is capable of pressing uniformly a thermal sensitive head against a platen, thereby improving printing quality. The press device comprises a platen disposed to be in contact with a thermal sensitive head having a sufficient length to carry out printing of every line and adapted to feed a dye film and a printing sheet and a holder adapted to force the thermal sensitive head to be in contact with the platen and to be separated from the platen. The press device also comprises a pair of plates both fixedly mounted on opposite ends of the thermal sensitive head, respectively, protrusions extending from the plates to outward direction of the thermal sensitive head, throughout holes adapted to receive the protrusions such that opposite ends of the thermal sensitive head move upwardly and downwardly, independently of each other, and a center member fixed to the holder and adapted to force the thermal sensitive head to be in close contact with the platen. With this construction, the thermal sensitive head is coupled to the holder such that the thermal sensitive head is inclined throughout the length thereof, according to the direction and the angle of the inclination of the platen.
