Abstract
The present invention relates to a paper supply control device and, specifically, to a paper supply control device which performs printing on printing paper by applying heat to an ink ribbon, performs de-curling with respect to the printing paper of which printing has been done, and then controls feeding and a transfer path of the printing paper so as to provide the printing paper to a user.
Claims8
A paper feeding control device for controlling feeding of printing paper in a thermal transfer printer, comprising:
- a driving gear (110) having teeth formed along the outer periphery thereof in such a way as to engage with a motor gear;
- a driving shaft (DR-X) whose one side end portion fittedly coupled to a rotating center of the driving gear (110);
- a driven rotating plate (120) having a rotating center to which the other side end portion of the driving shaft (DR-X) is fittedly coupled;
- a shaft gear (130) having a rotating center through which the driving shaft (DR-X) fittedly passes in such a way as to rotate together with the driving shaft (DR-X);
- an idle gear (140) engaging with the shaft gear (130) and thus rotating;
- a first cam (150) coupled to the idle gear (140) in such a way as to rotate together with the idle gear (140) and adapted to change the rotational direction of a diverter (16) selecting a transfer path of the printing paper according to the rotating angle thereof;
- a pair of second right and left cams (122 and 160) located on one side of the driving gear (110) and on one side of the driven rotating plate (120) to perform the same operation as each other;
- a pair of third right and left cams (123 and 170) located on the other side of the driving gear (110) and on the other side of the driven rotating plate (120) to perform the same operation as each other;
- a pair of platen brackets (180) rotatably coupled to both ends of a platen roller (15) in such a way as to allow an upper end portion thereof to rotate around a rotating center point formed on a lower end portion thereof by means of the second cams (122 and 160) to operate the platen roller (15);
- and
- a pair of pressurizing brackets (190) rotatably coupled to both ends of a pressurizing roller (11b) in such a way as to allow an upper end portion thereof to rotate around a rotating center point formed on a lower end portion thereof by means of the third cams (123 and 170) to operate the pressurizing roller (11b).
