The printing pressure roller is held by a frame pivotally attached to the card, and the printing pressure roller is rolled into contact with the credit card inserted on the base via the printing paper so that the printing paper is placed on the credit card. In the printing device configured to print the information display code printed on the printing base, the printing base and the credit card setting base are integrally formed of synthetic resin, and the periphery of the base except for the card insertion slot is formed to be thin. In addition, a reinforcing beam portion is formed on the back surface of the base, and the back lid holding a plurality of level adjusting screw bodies, each end of which abuts on the beam portion side via a pad, is attached to the printing base. Solid ,
The height level of the base is adjusted by the screwing amount of the screw body.

[Operation] In the present invention, since the printing base and the credit card setting base are integrally formed of synthetic resin, assembly is easy, the manufacturing can be performed at low cost, and the periphery of the base is thinned to adjust the position. The height of the base is made variable by the amount of screwing of the screw body, so the adjustment of the position adjustment operation is regulated by the thin part and the adjustment amount is prevented from being excessive or insufficient, so that the height position of the base can be easily adjusted. Can be fine-tuned.

Reference numerals 18 and 18 denote positioning rollers fitted at both ends of the printing pressure roller 12, and reference numerals 19 and 19 denote operating body guides formed on the upper surface of the cover 13.

The free end of the frame 3 has a downward latch on one side.
20 is pivotally mounted, and is constantly receiving a spring force toward the base end of the frame 3 by a spring (not shown). The printing base is closed at a position where the frame 3 is closed with respect to the printing base 1 side. It is set so as to be removably locked to the locking projection 21 on the base 1 side.

The base 2 has a shallow paragraph-shaped card positioning recess.
Further, one side in the width direction of the base 2 is set as a card insertion slot 23 into the card positioning recess 22, and a pair of card insertion guide pieces 24 is provided on both sides of the card insertion slot 23. , 24 are provided. Card slot 23 above
Except for the above, the thin portion 25
Are formed along the U-shape, and a reinforcing beam 26 as shown in FIG. 5 is integrally formed on the back surface of the base 2.

On the back side of the printing base 1, a metal back cover 27 is fixed with a plurality of fixing screws 28 as shown in FIG.
A plurality of, for example, four level adjusting screw bodies 29 are screwed to the back cover 27 corresponding to the lower surface of the beam portion 26.
Each tip of these screw bodies 29 is pressed against the beam 26.
The height level of the credit card setting base 2 including the inclination of the credit card setting base 2 can be changed via the pad 30 and the beam 26 according to the screwing amount. The level adjusting member 31 is composed of the back cover 27 and the like. Numeral 32 denotes a nut screwed onto the fixing screw 28.

 Next, the operation of the above configuration will be described.

First, the credit card M is guided between the pair of insertion guide pieces 24, 24 in the credit card setting base 2 from the direction of the white arrow in FIG. 4 to be set in the card positioning recess 22 as shown in FIG. After the printing paper N is placed thereon, the frame 3 is rotated against the spring force of the coil springs 8 and 8 to close the printing base 1. In this case, if one end of the printing paper N is inserted under the connecting portion 9 of the coil springs 8 and 8, the interlocking portion 9 is rotated by the rotation of the frame 3.
Presses one end of the printing paper N downward as a pressing member, so that the printing paper N is fixed without fear of displacement.

On the other hand, when the frame 3 is closed, the leading end of the latch 20 engages with the locking projection 21 on the printing base 1 side with a spring force in the left direction in FIG. The locked position is maintained in the closed position.

In this state, if the roller operating body 16 is moved rightward from the non-printing position shown in FIGS. 1 and 2, the printing roller 4 also rolls along the guide hole 11 in the same direction. When the printing pressure roller 4 passes over the information display code m such as the user name engraved on the credit card M, the printing paper N is pressed against the information display code m and the user touches the printing paper N with the user. The name is printed.

When the printing is completed, the latch 20 is moved to the first position against the spring force.
If the frame 3 is released from the printing base 1 side by the spring force of the coil springs 8 and 8 when the engagement with the locking projection 21 is released by a pulling operation to the right in FIG. The printing paper N can be taken out.

Here, since the credit card setting base 2 is integrally formed with the printing base 1 made of a synthetic resin, the number of components is reduced, the assembling is facilitated, and the cost can be reduced.

By the way, when printing unevenness occurs on the printing target paper N,
What is necessary is just to adjust the screwing amount of the screw body 29 for level adjustment with respect to the credit card setting base 2. That is, since the credit card setting base 2 can be slightly displaced in the vertical direction by the surrounding thin portion 25, the screw body
If the screwing amount of the screw 29 is appropriately changed, a pressing force acts on the beam portion 26 via the backing plate 30, so that the height level including the inclination of the base 2 can be adjusted. Therefore, even if there is a variation in the thickness of the credit card M or the like, an appropriate turning state by the printing pressure roller 4 can be obtained.

In particular, since the credit card setting base 2 is formed integrally with the printing base 1 and the thin portion 25 is formed around the base 2, the screwing of the screw body 29 can be controlled by the thin portion.
The height of the base 2 can be finely and accurately adjusted by regulating the height of the strut 25, so that the amount of adjustment is small or small. As a result, a high-precision printing pressure state can be obtained irrespective of the formation distortion and the like due to the base 2 being integrally formed with the printing base 1, and it is possible to reliably prevent the printing pressure unevenness and the like.

[Effects of the Invention] As described above, according to the invention, the periphery of the credit card setting base integrally formed of the synthetic resin on the printing base is formed to be thin, and the beam portion is formed on the back surface of the base. Since the tip of the screw body for level adjustment held on the back lid of the printing base is brought into contact with the beam, the height level of the base is adjusted by the screwing amount of the screw body. The above level can be easily fine-tuned regardless of the thickness of the credit card or the molding distortion of the base. Also, the number of parts is smaller than the conventional one,
An inexpensive product having excellent assemblability can be obtained.
