Then, the entrance-side paper sensor 3 detects the leading end of the inserted invitation ticket P1, the entrance-side transport roll 4 is driven to rotate, and the invitation ticket P1 is transported downstream. During this transport process, the scanner unit 5 reads the invitation ticket P1 (step S2), and stores the read first image data in the base storage unit 31 (step S3).
[0039]
The invitation ticket P1 that has passed through the scanner unit 5 is further transported downstream on the document transport path 2 by the rotation of the entrance-side transport roll 4 and the exit-side transport roll 9. When the exit paper sensor 10 detects the rear end of the invitation ticket P1, the rotation of the entrance transport roll 4 and the exit transport roll 9 is stopped. This completes the operation of reading the invitation ticket P1 before writing. The platen roll 8 may be used to transport the invitation ticket P1.
[0040]
When the reading of the invitation ticket P1 before the additional writing is completed, the display content of the display unit 26 is switched to the display content shown in FIG.
[0041]
Next, the user additionally writes the invitation ticket P1 in FIG. 15 and inserts the additionally written invitation ticket P2 shown in FIG. Then, the entrance-side paper sensor 3 detects the leading end of the inserted invitation ticket P2, and the entrance-side transport roll 4 is driven to rotate to transport the invitation ticket P2 to the downstream side. In this transport process, the scanner unit 5 reads the invitation ticket P2 (step S4), and stores the read second image data in the area storage unit 33 (step S5).
[0042]
The invitation ticket P2 that has passed through the scanner unit 5 is further transported downstream on the document transport path 2 by rotation of the entrance-side transport roll 4 and the exit-side transport roll 9. When the exit paper sensor 10 detects the rear end of the invitation ticket P2, the rotation of the entrance conveyance roll 4 and the exit conveyance roll 9 is stopped. Thus, the reading operation of the invitation ticket P2 after the additional writing is completed. The platen roll 8 may be used to transport the invitation ticket P2.
[0043]
When the reading of the invitation ticket P2 after the additional writing is completed, the first image data of the base storage unit 31 and the second image data of the area storage unit 33 are transferred to the comparison circuit 29, and the comparison circuit 29 reads both images. A different part of the data is extracted as additional data, and the additional data is stored in the additional data storage unit 32 (step S6). Further, the additional data is transferred to the area specifying unit 30, and the area specifying unit 30 specifies an area of the additional data to which the specified value is added in the main scanning direction and the sub-scanning direction. Is created, and this area data is transferred to the area storage unit 33, where it is stored (step S7). The data stored in the area storage unit 33 is updated from the second image data to the area data.

The timing at which the leading end of the invitation ticket P1 is conveyed to a position between the thermal head 7 and the platen roll 8 is determined based on the detection time point at which the leading end of the invitation ticket P1 is detected by the paper sensor 6. As a result, the thermal head 7 is shifted from the standby position to the pressing position, and the rotation of the platen roll 8 is started. Further, the take-up reel 14 is driven to rotate, and the movement of the ink ribbon 12 is started. In the pressurized conveyance process, character printing based on the additional data in the additional data storage unit 32 is performed on the invitation ticket P1. The positions and contents of the character printing are the positions and contents shown in FIG. 17, and the additional printing provides an invitation ticket having the same contents as in FIG. Hereinafter, the additionally printed one will be described as the invitation ticket P2.
[0049]
Further, when the pressurizing timing paper sensor 6 detects the rear end of the invitation ticket P2, the rear end of the invitation ticket P2 passes between the heat-sensitive head 7 and the platen roll 8 based on this detection time. The thermal head 7 is moved to the standby position, and the rotation of the platen roll 8 is stopped. Further, the rotation drive of the take-up reel 14 is also stopped, and the movement of the ink ribbon 12 is stopped. Even after these operations, the rotational drive of the entrance-side transport roll 4 and the exit-side transport roll 9 is continued, and the invitation ticket P2 is transported downstream. When the exit paper sensor 10 detects the rear end of the invitation ticket P2, the rotation of the entrance conveyance roll 4 and the exit conveyance roll 9 is stopped. This completes the character printing operation (step S16).
[0050]
Next, when the user performs area printing (overcoating layer printing) in the invitee column of the invitation ticket P2, the user presses the second selection switch 28b (step S15). Then, the display content of the display unit 26 is switched to the display content shown in FIG.
[0051]
After replacing the ribbon cassette 11 with a ribbon cassette made of transparent ink, the user inserts the invitation card P2 after the additional writing shown in FIG. Then, the entrance-side paper sensor 3 detects the leading end of the inserted invitation ticket P2, and the entrance-side transport roll 4 is driven to rotate to transport the invitation ticket P2 to the downstream side. The leading end of the invitation ticket P2 is conveyed to a position between the thermal head 7 and the platen roll 8 based on the detection point when the pressing timing paper sensor 6 detects the leading end of the invitation ticket P2. The timing is determined. At this timing, the thermal head 7 is shifted from the standby position to the pressing position, and the rotation drive of the platen roll 8 is started. In addition, the take-up reel 16 is driven to rotate, and the movement of the transparent ink ribbon is started. In the pressurized conveyance process, area printing based on the area data in the area storage unit 33 is performed on the invitation ticket P2. The position and the content of the area printing are an area E surrounded by a virtual line in FIG. 17, and the transparent ink is printed on this area E. Thereby, the invitation column (area E) is covered by the overcoating layer of the transparent ink, and the invitation card P2 protected is obtained.
[0052]
Further, when the pressurization timing sheet sensor 6 detects the rear end of the invitation ticket P2 being conveyed, the rear end of the invitation ticket P2 passes between the heat-sensitive head 7 and the platen roll 8 based on the detection time. The thermal head 7 is moved to the standby position, and the rotation of the platen roll 8 is stopped. Further, the rotation drive of the take-up reel 14 is also stopped, and the movement of the ink ribbon 12 is stopped. Even after these operations, the rotational drive of the entrance-side transport roll 4 and the exit-side transport roll 9 is continued, and the invitation ticket P2 is transported downstream. When the exit paper sensor 10 detects the rear end of the invitation ticket P2, the rotation of the entrance conveyance roll 4 and the exit conveyance roll 9 is stopped. Thus, the area printing operation is completed (Step S17).
