A more detailed technical structure of the printing ribbon normal / reverse driving means 40 applied to the present invention is as follows.

That is, the frame 41 is provided with the drive pulley 42 and the driven pulley 43 assembled thereto.

And a drive pulley 42 which is installed at the lower end of the frame 41 and rotatably installed on the shaft of the drive motor 11 is provided.

And a driven pulley 43 assembled at the upper end of the frame 41 and rotating according to the rotation of the drive pulley 42.

And an O-ring belt 44 is provided on the outer circumferential surface to rotate the drive pulley 42 and the driven pulley 43 together by frictional force.

In addition, the driven pulley 43 is integrally provided with an operating gear 46 for selectively interlocking with the wind-up gear 20 or the rewind gear 30.

On the other hand, the frame 41 applied to the present invention is provided with a friction-preventing sliding member 45 for reducing the friction of the O-ring belt 44 in a state where the frame 41 is sandwiched between the X-

It is preferable that the O-ring belt 44 applied to the present invention is wound around the driven pulley 43 and the drive pulley 42 in an eight-letter shape in order to prevent loosening and slimness.

4 is a perspective view of the printed ribbon driving apparatus of the card printer according to the present invention in a coupled state and shows a state in which the printing ribbon normal and reverse driving means 40 is engaged with the rewind gear 30 to rewind the ribbon .

In particular, FIG. 5 applied to the present invention is a front view of a combined state in which a printing ribbon driving apparatus of a card printer is shown, in which a printing ribbon normal / reverse driving means 40 is shown engaged with a wind- .

6 is a front view of a combined state in which the printing ribbon driving device of the card printer according to the present invention is shown, in which the printing ribbon normal / reverse driving means 40 is engaged with the rewind gear 30 and rewinds the ribbon .

The function and effect of the present invention will be described in more detail as follows.

3 and 5, when the drive pulley 42 is reversely rotated by the reverse drive (counterclockwise) of the drive motor 11, the o-ring belt 44 rotates in the direction of the arrow, Rotates by the mutual frictional force with the pulley and consequently rotates the print ribbon normal / reverse driving means 40 to the left in the drawing.

When the driven pulley 43 is rotated forward by the rotation of the O-ring belt 44, the actuating gear 46 provided on the rear side also rotates forward.

In addition, due to the forward rotation of the operating gear 46, the wind-up gear 20 meshed with the wind-up gear 20 reversely rotates. By reverse rotation of the wind-up gear 20, And the winder gear 21 performs a final positive rotation of the winder driven gear 22 interlocked with the winder gear 22 to perform a winding function.

4 and 6, when the drive pulley 42 is rotated forward by the forward motion (clockwise direction) of the drive motor 11, the o-ring belt 44 rotates in the direction of the arrow, The belt is rotated by a mutual frictional force with the pulley so that the printing ribbon normal / reverse driving means 40 is rotated to the right in the drawing.

When the driven pulley 43 is reversely rotated by the rotation of the O-ring belt 44, the actuating gear 46 provided at the rear side is also rotated in the reverse direction.

The reverse rotation of the operating gear 46 causes the rewind gear 30 to rotate in a forward direction and the rewind small gear 31 provided at the rear side by the forward rotation of the winder gear 30 And the rewind small gear 31 functions as a releasing function by finally rotating the rewound ribbon take-up gear 32 interlocked with the rewind small gear 31 in the final reverse direction.

In the meantime, the print ribbon normal / reverse driving means 40 applied to the present invention is constituted such that a frictional anti-slip member 45 provided horizontally in the frame 41 is inserted into an X- (44).

Finally, the o-ring belt 44 applied to the present invention is wound around the driven pulley 43 and the drive pulley 42 in an eight-letter shape to obtain the effect of preventing loosening and slimness.

The technical idea of the printing ribbon driving device of the card printer of the present invention is that the same result can be repeatedly practiced. Especially, by implementing the present invention as described above, it is possible to contribute to industrial development by promoting the technological development.
