The thermal transfer head 4 is moved back in the arrow e direction. Then, almost at the same time when the stage 2 is returned to the original position P ₁ , the thermal transfer head 4 moves the unused card 1 on the stage 2 to the approximate center position between the pair of winding drums 40 and 41 of the ink ribbon 3. The upper end of the arrow a direction is pressed from above.

The fact that the stage 2 is moved back to the original position P ₁ shown by the solid line in FIGS. 3 and 6 indicates that the sensor S ₁

[0063]

The card printing apparatus of the present invention configured as described above has the following effects.

By simply moving the stage in and out of the bottommost card in the card stock section arranged adjacent to the card printing section on the moving path of the stage which is moved in parallel, the stage for card printing is parallelized. Since the card can be automatically mounted on the stage by using the movement, it is not necessary to provide the card mounting device separately from the card printing device. Further, since the drive system of the stage can be used for the card mounting mechanism, the structure is simple and the manufacturing can be performed at low cost.

Since the card stock section can be arranged on the moving path of the stage, the space factor is improved and the miniaturization of the entire apparatus can be promoted.

Since the card can be automatically mounted on the stage by utilizing the parallel movement of the stage for card printing, the automatic card mounting operation can be performed smoothly, smoothly and with high efficiency.
