ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a caption printer, and more particularly to a system capable of automatically dispensing copperplates one by one in sequence to be used in imprinting captions on a film in a caption printer.
2. Description of the Related Art
According to a conventional method for imprinting captions on a film for motion pictures, movies, etc., a flexible film is pressed on a copperplate on which a desired caption is embossed, so that the caption is imprinted on the film.
In a conventional caption printer using the conventional method, the copperplate is placed on a stand, and a film drawn out from a winding roll on which the film is wound is positioned above the copperplate. Also, a pressing plate of an actuator moving down from above presses the film onto the copperplate, so that the caption is imprinted on the lower surface of the film.
The copperplates are drawn out from a supplying casing and placed onto the stand one by one, and are put one by one into a storing casing after being used in imprinting a caption on a film.
In such a case as above in which the copperplates are drawn out and stored one by one by a worker's manual operation, it takes considerable time and expense in supplying and storing the copperplates. This problem deteriorates the efficiency of the labor and the competence of the caption printer in the market. Moreover, the manual operation of drawing out and storing the copperplates disturbs a complete automation of the caption printer. Also, the productivity is not increased in the prior art.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been made in an effort to solve the problems occurring in the related art, and it is an object of the present invention to provide a system for dispensing copperplates for imprinting captions on a film in a caption printer, in which the copperplates stored in pitches of a coil spring are automatically dispensed by a driving force of a motor, thereby achieving a complete automation in imprinting captions on a film, and reducing time and labor spent in imprinting captions on the film.
In accordance with one aspect, the present invention provides a system for dispensing copperplates for imprinting captions on a film in a caption printer, the system comprising:
a casing shaped as a slim tube whose upper end is open, the casing having an inclined guiding hole extending through a lower portion of the casing in an inclined direction;
a coil spring longitudinally inserted in the casing, the coil spring being wound in such a manner as to have a plurality of pitches between turns of the coil spring, in each of which can be received each of the copperplates; and
a rotation shaft fixed to a lower end of the coil spring so as to rotate the coil spring,
wherein the copperplates can be inserted through the upper end of the casing and guided into each of the pitches one by one in sequence while the rotation shaft together with the coil spring is rotated, and the copperplates can be dispensed out of the casing through the inclined guiding hole one by one in sequence at each rotation of the coil spring.
Preferably, the system further has a supporting plate installed at a front position of the caption printer, a supporting bracket fixed on the supporting plate, a rotating plate received in the supporting bracket, and a motor for rotating the rotating plate. A lower end of the casing is fitted in the supporting bracket, and the rotating plate has a center shaft assembled with the rotation shaft in the supporting bracket, so that the rotation shaft is rotated by a driving force of the motor.
More preferably, the rotation shaft and the rotating plate respectively have first and second engaging pins which are engaged with each other, so that a rotational force of the rotating plate by the motor is transferred through the first and the second engaging pins to the rotation shaft. The coil spring may be a spiral spring in which a rectangular metal wire is wound in a spiral shape.
