  • Patent number: 5293183
    Abstract: The present invention relates to heat blowing equipment for a thermal print head of a color video printer, in which a radiating plate is mounted on the upper surface of the thermal print head and a ventilation fan is directly connected to the upper portion of the radiating plate, thereby being moved together with the head during the up and down operation of the head. Accordingly, a proper temperature is continuously maintained regardless of any position change of the head. The ventilation fan is mounted on a fan guide, which is coupled to the radiating plate by a plurality of levers, so that the structure always effectively cools the thermal print head regardless of any position change of the head.

  • Patent number: 5272488
    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.
