DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a certificate printing and issuing device for printing and issuing, for example, a resident's card in a local government, various certificates in a university or other educational institution, and more particularly to a printing unit for printing a predetermined format part. The present invention relates to a certificate print issuance apparatus having a function of connecting a printing unit for performing printing for certification by embossing and having a function of simultaneously or collectively discharging a plurality of certificates.

[0002]

2. Description of the Related Art Conventionally, when issuing a resident's card at a local government, various certificates at a university or other school institution, etc., in most cases, an original is extracted and copied, and then a seal or a certification seal is printed and issued. In many cases, these issuance operations are manually performed, and it takes a long time from requesting certificates to printing.

In recent years, devices having a function of automatically printing and issuing various certificates under the control of a computer from a database stored in advance have emerged, and the conventional manual work has been greatly reduced. The time required is decreasing.

[0004]

However, in the above-mentioned conventional apparatus, the contents of a predetermined format are merely printed and issued, and the certification stamp is still often manually formed, and the certification portion is printed by embossing or the like. In most cases, the devices are separately installed, and the requester of the certificates has a complaint that the waiting time is long.

Further, even when a plurality of certificates are printed, a dedicated stacker is required as a result of discharging one sheet, which causes a problem that the configuration of the entire apparatus becomes large and complicated. When a plurality of sheets are stored in the stacker or the storage unit, a means for preventing the sheets from being dissipated due to wind or the like during storage is necessary. There is something.

FIG. 16 is an explanatory view showing an example of a paper pressing means provided near a paper discharge port of a paper transport mechanism in a conventional apparatus. In FIG. 16, reference numerals 101 and 102 denote an upper guide and a lower guide, respectively, which are provided to face each other with a slight space therebetween, form a paper transport path, and serve as guides for transporting the paper in the arrow direction. Reference numerals 103 and 104 denote transport rollers, respectively, for pinching the paper and discharging the paper to the discharge port 105. Reference numeral 106 denotes a pressing roller, which is urged against the lower guide 102 by a spring 107, for example.

With the above configuration, a pair of rollers 103,
By rotating the sheet 104 in a contact state, the sheet (not shown) is pinched and transported in the left direction of the arrow. When the leading edge of the paper slightly protrudes from the discharge port 105, the roller 1
The rotation of the rollers 103 and 104 is stopped, and the roller 103 is retracted upward as indicated by the arrow. In this case, since the sheet is pressed against the lower guide 102 by the pressing roller 106, the sheet is held without being blown off by wind or the like. When the requester or the user pulls out the sheet with the leading end thereof, the pressing roller 106 rotates with the drawing of the sheet, and the sheet is discharged.

However, when the pressing roller 106 as shown in FIG.
Therefore, it is necessary to provide a means for releasing the paper holding state, thereby complicating the apparatus configuration. Further, since the pressure roller 106 is always present in the paper transport path, there is a problem that the transport of the paper may be hindered.

The present invention solves the above-mentioned problems of the prior art, and can automatically or simultaneously issue the number of certificates requested by the claimant with a relatively simple structure. It is an object to provide a print issuing device.

[0010]

In order to achieve the above object, according to a first aspect of the present invention, there is provided a certificate print issuance apparatus configured to certify a sheet printed in a predetermined format.

At this time, the memory in the control unit 15 adds one to the number of sheets stored in the temporary stack unit (25).

Next, it is confirmed whether or not printing has been completed for all the number of sheets requested by the claimant (26). If printing has been completed, the temporary stack portion storage is discharged (28) and the process is terminated (29). If the printing has not been completed, the number of bills, that is, the number of batch discharges, and the number of sheets stored in the temporary stack unit are compared (27). If the numbers match, the temporary stack portion storage amount is discharged (28), and then the temporary stack portion storage number is set to 0 (22), and the steps after step 22 are repeated. On the other hand, if the numbers do not match, the above steps 23 to 26 are repeated, and after the predetermined number is temporarily stored in the stacking section, the sheet transport mechanism 3 shown in FIG. The discharged sheets are collectively discharged (28) and terminated (29).

In the above-described embodiment, an example is described in which the batch discharge unit of sheets is designated by the number of sheets. However, a control mode in which the unit is designated by time may be adopted. That is, if the designation is made, for example, as "90 seconds", the printed sheets stored in the temporary stacking section 7 shown in FIG. 1 can be collectively discharged every 90 seconds. In this way, "you will not experience a feeling of frustration even if you wait within a few seconds."
It is easy to make a guide like that. In addition, it is also possible to adopt a batch discharge method in which the storage capacity of the temporary stack unit 7 is taken into consideration and the unit is combined in units of time or number of sheets.
