A platen 9 provided opposite to the lower part of the conveying surface of the passbook 12, a second stepping motor 8 for operating the platen 9 in the vertical direction, and feed rollers 3, 10 arranged before and after the protector 22 to convey the passbook 12; And a third stepping motor 11 for driving the feed rollers 3 and 10 to rotate.

Referring to FIG. 9 and FIG. 10, the protector 22 has a rib 77 at a position covering the entire sensor lens 13 on the conveyance guide surface 50, and penetrates through the center of the rib 77 at the position of the sensor lens 13. Holes are provided. The rib 77 has a configuration having an inclined surface 77 a from the transport guide surface 50 in the transport direction J of the passbook 12.

Next, the operation of the passbook printer 100 configured as described above will be described with reference to FIGS.

When the passbook 12 is conveyed to the lower position of the reflection type sensor 1 by the feed roller 10 through the conveyance guide surface 50 of the protector 22 and the inclined surface 77a of the rib 77, the passbook 12 is lowered when the passbook 12 is conveyed. Platen 9
Performs an ascending operation until it hits the protector 22, and then descends by a specified amount after hitting, thereby controlling the distance between the protector 22 and the platen 9.
Platen 9 and tip 77b of rib 77 of protector 22

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the passbook printer of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing the passbook printer 20 of the present invention, FIG. 2 is a front view showing the passbook printer 20 of the present invention,
FIG. 3 is an enlarged cross-sectional view taken along the line AA of FIG. 1, and FIG. 4 is a view showing an arrow C in FIG. The same components as those of the conventional passbook printer 100 are denoted by the same reference numerals.

Referring to FIGS. 1 and 2, a passbook printer 20 of the present invention includes a print head 6 for printing, a transport guide surface 25 of the passbook 12 located around the print head 6, a sensor lens 13, 2, a printer carrier 5 having a print head 6 and a protector 2, a first stepping motor 4 for operating the printer carrier 5 in the lateral direction, and a reflection type sensor. A platen 9 provided at a lower portion of the transport surface of the passbook 12 facing the sensor 1, a second stepping motor 8 for operating the platen 9 in the vertical direction, and a feed roller disposed before and after the protector 2 to transport the passbook 12 3 and 10 and a third stepping motor 11 for driving the feed rollers 3 and 10 to rotate.

Referring to FIGS. 3 and 4, the protector 2 has a transport guide surface 25 and a sensor lens 13 arranged on the same plane, and the transport guide surface 25 has a rib 7 covering a part of the sensor lens 13. The rib 7 has an inclined surface 7 a from the conveyance guide surface 25 in the conveyance direction H of the passbook 12, and a through hole having a diameter equal to or larger than the diameter of the sensor lens 13 with respect to the center position of the sensor lens 13 is provided. The reflection type sensor 1 is provided with an optical sensor including a light emitting diode (not shown) and a phototransistor (not shown).

Next, with respect to the operation of the passbook printer 20 configured as described above, FIG. 5 shows a state in which the tip 12a of the passbook 12 is transported to a position on the surface of the sensor lens 13.
(A), FIG. 5 (b) showing a state in which the barcode of the passbook 12 has been transported to a position where it can be read by the reflective sensor 1,
This will be described with reference to FIGS.

By the feed roller 10, the passbook 12 passes through the transport guide surface 25 of the protector 2, and as shown in FIG. 5A, passes on the surface of the sensor lens 13 arranged on the same plane as the transport guide surface 25. After self-cleaning is performed by the tip 12a of the
When the passbook 12 is conveyed to the lower position of the reflective sensor 1 through the inclined surface 7a of the rib 7 as shown in (b), the lowered platen 9 hits the protector 2 when the passbook 12 is conveyed. (Not shown), and after abutting, by lowering by a specified amount, by controlling the distance between the protector 2 and the platen 9, the platen 9 and the tip 7 b of the rib 7 of the protector 2 are separated. It is kept at a certain distance and suppresses fluttering of the passbook 12,
The distance between the sensor lens 13 and the surface of the passbook 12 is kept constant. In this state, the optical axis 14 of the reflection type sensor 1
, And the barcode of the passbook 12 is read.

In the case of reading a vertical barcode of the passbook 12, the reflection type sensor 1 operates in the horizontal direction together with the printer carrier 5 while the passbook 12 is stopped, and in the case of reading a horizontal barcode, the printer carrier 5 stops. The passbook 12 operates in the transport direction H in a state where the reflection type sensor 1 is stopped, and the reading operation is performed by the reflection type sensor 1.

At a position where the passbook 12 is further conveyed by a predetermined amount from the barcode reading position of the passbook 12, the platen 9
Performs the ascending operation until it hits the protector 2, and after hitting, lowers by a specified amount to control the distance between the print head 6 and the platen 9, and keeps the distance between the print head 6 and the passbook 12 constant. In this state, a printing operation is performed.

Next, a comparison test result between the passbook printer 20 of the present invention and the conventional passbook printer 100 will be described.

The results of an accelerated running test equivalent to one year as the total number of transfers of the passbook 12 (assuming that the number of transactions is 100,000) and the amount of change in the output of the reflective sensor 1 due to contamination of the sensor lens 13 are shown in FIG. FIG. In the comparative test, two passbook printers 20 of the present invention and two conventional passbook printers 100 were used.

Referring to FIG. 7, in the passbook printer 20 of the present invention, the output decrease amount of the reflection type sensor 1 is an output level decrease of 0.23 V on the average of two sensors. The result that the output reduction amount of the mold sensor 1 was 1.66 V on the average of two units was obtained. Reading of the barcode of the passbook 12 requires 1.5 V or more as the output of the reflection sensor 1, but one of the conventional passbook printers 100 after the acceleration running test cannot read the barcode. Although a problem occurred, both of the passbook printers 20 of the present invention showed a small amount of decrease in the output of the reflective sensor 1 as described above, and a result having a sufficient margin as the output of the reflective sensor 1 was obtained.

[0031]

As described above, when the passbook is conveyed on the conveyance guide surface, the tip of the passbook comes into contact with the sensor lens surface, thereby removing dust and paper dust attached to the sensor lens surface. After cleaning,
The sensor lens is cleaned by moving the passbook even when dust, paper dust, etc. adhere to the sensor lens because the sensor lens is separated from the sensor lens by climbing on the inclined surface of the rib. Even if ink adheres to other parts, there is an effect that ink does not adhere because the sensor lens does not contact the passbook printing surface.

Further, even during the printing operation, the sensor lens is always separated from the surface of the passbook by the height of the rib.
There is an effect that the sensor lens is not stained.
