DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic explanatory view of the whole embodiment of the present invention. In the figure, inside the case body 1, a certification content printing printer for printing the certification content, for example, a laser beam printer 2, and a sheet printed by the laser beam printer 2 are provided on the outer surface of the case body 1. A sheet conveying means 4 for conveying to the position of the shutter 3, an embossing print printer 5 for proof-printing in a concave-convex form in order to prove the print content printed by the laser beam printer 2 in the middle of the sheet conveying means 4, ID An ID card reading unit 6 for reading a card, an input unit 7 for inputting a personal identification number and a desired type of certificate, a display unit 8 for displaying the operation method of the device, certificate options, etc., and a fee for issuing a certificate. It manages the money transfer unit 9 that transfers money, the communication unit 10 that communicates with the host computer that manages the certificate database, and the control of a series of operations of each device. Control unit 11 and the like.

The certificate issuing operation will be briefly described as follows. When the issue of a certain certificate is designated from the input unit 7, the laser beam printer 2 communicates with the host computer via the communication unit 10 and transmits / receives the data necessary for issuing the certificate. The paper printed with the certification content is ejected.

The sheet is composed of two guide plates 12-1, 12
It will be introduced during -2. Sensor 13-
When 1 detects the leading edge of the paper, the drive guide roller 14 of the paper carrying means 4 is driven by the paper carrying motor 15 and is driven at the same speed as the paper feeding speed of the laser beam printer 2. When the sensor 13-1 detects the trailing edge of the paper, the paper feed control is performed regardless of the paper feed speed of the laser beam printer 2.

The embossing print printer 5 is provided with a sensor 13-2 for detecting the leading edge of the sheet and either one of the left edge and the right edge. The sensor 13-2 detects the sheet position to detect an input portion. Paper feeding control for embossing printing is performed at a predetermined position on a predetermined paper of the certificate designated from 7.

The paper on which the embossing printing printer 5 has embossed printing on a predetermined position of the paper, that is, the certificate, is fed and stored in a temporary stack portion 16 formed by the guide plates 12-4 and 12-5. . The embossing print printer 5 will be described with reference to FIG.

When such a series of steps are repeated and the number of sheets designated by the input section 7 is accumulated in the temporary stack section 16, the solenoid 17-1 pushes the guide plate 12-4 to the guide plate 12-5 side. increase. The predetermined number of certificates sandwiched between the guide plates 12-4 and 12-5 are conveyed toward the shutter 3 provided on the outer surface of the case body 1. The shutter 3 is opened each time the solenoid 17-2 operates when the sensor 13-3 detects the leading edge of the sheet. At this time, the solenoid 17-2 operates,
The lower guide plate 12 of the guide plates 12-6 and 12-7
The passage switching is performed by lowering the left end of -7 from the guide plate 12-4.

Therefore, the predetermined number of certificates are conveyed until the leading edge of the certificate is slightly exposed from the shutter 3. On the other hand, when the certificate remains at the shutter 3 even after a lapse of a predetermined time after the certificate is detected by the sensor 13-3, the drive guide roller 14 of the sheet conveying means 4 rotates in the reverse direction, and the shutter 3 moves. The remaining certificates in place will be transported back.

As described above, since the guide plate 12-7 is lower than the guide plate 12-4, the certificate conveyed in the reverse direction passes between the guide plates 12-6 and 12-7 and is conveyed in the conveying path. And is conveyed to the reject stacker 19. At this time, the sensor 13-4 has detected the conveyance of the certificate to the reject stacker 19, and based on this detection, for example, this history information is stored in the memory of the control unit 11.

FIG. 2A is a side view of one embodiment of the embossing print printer, and FIG. 2B is a top view of FIG. 2A. In FIGS. 2A and 2B, reference numeral 21 denotes a carriage, which is movably attached to rails 22-1 and 22-2. A ribbon cassette 24 is swingably provided on the carriage 21 via a shaft 23, and an embossing print head 25 is provided on the inner surface of the ribbon cassette 24. The embossing print head 25 is fixed to the ribbon cassette 24 by screwing (not shown).

A drive mechanism (not shown) is provided on the carriage 21.
Is provided, and has a structure in which the side face of the ribbon cassette 24 is pushed down by the shift lever 28 with the shaft 34 as a fulcrum by the drive mechanism.

Therefore, when a signal for operating the drive mechanism is input from a signal cable (not shown), the drive mechanism causes the shift lever 28 to push down the side surface of the ribbon cassette 24, and the ribbon cassette 24 tilts as shown in FIG. 24-1 is out of the printing position between the tip of the embossing print head 25 and the platen 30. That is, the ribbon 24-1 is in a shifted state.

FIG. 4 is a bottom view of an embossing print head according to an embodiment, in which a predetermined number of pins 31 for giving a dot impact are arranged. Since the pin 31 presses the paper in a needle shape in accordance with a predetermined printing type, emboss printing, that is, uneven printing on the paper is performed, and copying is substantially impossible.

When the ribbon cassette 24 is inclined and the ribbon 24-1 is printed as shown in FIG. 3, printing is performed on an uneven printing surface called so-called embossed logo printing (printing), and the ribbon is printed. When it is printed through, it is printed on an uneven printing surface with a ribbon color, which is so-called embossing imprinting (printing). Platen 30 at this time
Is formed of a low hardness member.

As another example, at the time of printing an embossed logo and an embossed imprint printed on the uneven printing surface described above, the platen 30 is molded with a low hardness rubber 31-1 as shown in FIG. The semi-peripheral surface that is used is used so that the unevenness of the printed surface is easily raised. The platen 30 has a half-circumferential surface formed of a high hardness rubber 31-2, and if a replacement seal stamp is used for the embossing print head 25 of FIG. 6, a normal imprint is made. If the print head is used, normal printing can be performed.

The platen 30 is switched by rotating it by a driving device such as a motor based on the position detection of the platen position detection sensor 32. The embossing print head 25 is replaced with a seal and a normal print head, and the platen 30
By switching to the corresponding hardness rubber, it is possible to issue a certificate according to the degree of importance, expanding its versatility.

Although the ribbon shift mechanism moves the ribbon cassette 24 with the shift lever 28 in FIG. 2, any other mechanism may be used.

[0026]

As described above, according to the present invention, proof printing can be performed with the embossed logo or the embossed stamp, and the original and the copy can be clearly distinguished. Therefore, copying becomes virtually impossible, and a copy-protected certificate can be issued.
