  FIG. 10 shows a flowchart of the coordinate calibration process in the print document management server apparatus 300. As shown in this flowchart, the coordinate calibration process includes a multi-tap information reception step S100 and a coordinate calibration step S200.

  FIG. 11 is a flowchart showing details of the multi-tap information receiving step S100. In the multiple tap information receiving step S100, first, in step S110, it is determined whether tap information has been received. Here, in the case of a negative determination, the process proceeds to step S170, and 0 is assigned to the coordinate calibration flag that is a variable, and the process is terminated. In the case of a positive determination that the tap information has been received, the process proceeds to step S120, the timer is started, and subsequently, in step S130, it is determined whether or not the predetermined time has elapsed. . Here, in the case of an affirmative determination that the predetermined time has elapsed, after stopping the timer in step S160, 0 is substituted for the coordinate calibration flag in step S170, and the process is terminated. In the case of negative determination that the predetermined time has not elapsed, the process proceeds to step S140, and it is determined again whether tap information has been received. If the determination is negative, the process proceeds to step S130 and the process is repeated. On the other hand, if the determination is affirmative, 1 is assigned to the coordinate calibration flag in step S150, and the process ends.

  FIG. 12 is a flowchart showing details of the coordinate calibration step S200. In the coordinate calibration step S200, it is first determined whether or not the coordinate calibration flag is 1 in step S210. Here, in the case of a negative determination, the process is terminated as it is. On the other hand, in the case of a positive determination, the process proceeds to step S220, and it is determined whether the distance between the two tapped positions is within a predetermined range using the tapped position coordinates included in the tap information. . Here, “distance is within a predetermined range” means that the difference between the distance between the positioning marks 404 and 405 shown in FIG. 3 and the distance between the two tapped positions is, for example, the distance. It means that it is within the range which can be calibrated by being within 5%. If it is determined in step S220 that the distance between the two is not within the predetermined range, the process ends. In the case of a positive determination that the mutual distance is within the predetermined range, the process proceeds to step S230, and it is determined whether the tapped position is within the predetermined range. Here, “the position is within a predetermined range” means, for example, that the distance between the positioning mark 404 in FIG. 3 and the first tapped position is within a predetermined range, and the positioning mark 405 is tapped for the second time. This means that the distance to the position is within a predetermined range. Here, it may be a requirement that these tapped positions are shifted from the reference coordinates by the same distance in the same direction. In step S230, if at least one of the positions is not within the predetermined range, a negative determination is made, and the process is terminated as it is. If each position is within the predetermined range and the determination is affirmative, the process proceeds to step S240, and tap information is used to determine whether the electronic pen 200 has tapped the paper 400 without ejecting ink. judge. Here, in the case of a negative determination that ink has been ejected onto the paper 400 and tapped, the processing is terminated. On the other hand, if the ink is not ejected and tapped without drawing on the paper, a positive determination is made, and the process proceeds to step S250, where the distance between the tapped positions and the design between the positioning marks 404 and 405 of the format are designed. Compare the distance and determine if they are different. If these distances are different and an affirmative determination is made, the process proceeds to step S260, and the tap position for coordinate calibration is corrected based on the tap position notified as tap information. In step S270, the corrected tap position is stored in the document management database 330 as the reference coordinate position, and the coordinate system of the format image with respect to the paper 400 (the coordinate system of the code image) is calibrated.

  Here, the correction of the tap position in step S260 is performed by, for example, setting the same length as the distance between the corresponding two positioning marks on the straight line connecting the two tap positions, the midpoint of the length, and the two taps. The midpoint of the position is taken to coincide, and correction is made so that there are two tap positions at both ends of the taken length.

  On the other hand, if a negative determination is made in step S250, the process proceeds to step S270, where the tap position is stored in the document management database 330 as the position of the reference coordinate as it is, and the form image paper 400 (coordinate of the code image) Calibrate the coordinate system relative to the system.

  FIG. 13 is a diagram showing a part of the document management database 330 calibrated by the coordinate calibration step S200 of FIG. The fields of the first reference coordinate and the second reference coordinate in the document management database 330 are the corrected reference coordinates. In the present embodiment, the reference coordinate is the position of the positioning mark when there is no printing deviation in the format image, but may be another position that can be derived from the tap position as long as the coordinate system can be determined. .

  Here, the paper ID and the format ID of the document management database 330 in FIG. 13 have been described as being associated with each other in advance, but when the paper ID and the format ID are not associated with each other, these associations are made. May be performed in a series of coordinate calibration processes. FIG. 14 shows a coordinate calibration process including a process for associating a paper ID and a format ID. As shown in FIG. 14, in the coordinate calibration process by the processing unit 320 of the print document management server apparatus 300 in this case, first, in the format identifier input process of step S300, the format ID printed on the sheet on which the coordinate calibration process is performed. Is entered. The input here may be input with a keyboard or a mouse, or may be input with a bar code or the like printed on a form by a dedicated reading device, and is directly input to the print document management server device 300. Or it shall be inputted via the network 150. Next, the multi-tap information receiving step (step S100) described with reference to FIG. 11 is performed on the sheet 400 on which the format image of the input format ID is printed. Since this process is the same as that of FIG. 11, description is abbreviate | omitted. Subsequently, in the format associating step in step S400, the processing unit 320 uses the format ID input in the format identifier input step (step S300) and the paper ID included in the tap information acquired in the multiple tap information receiving step (step S100). Associate and save. Finally, the coordinate calibration process (S200) described in FIG. 11 is executed. This step is also the same as the step described with reference to FIG. As a result, the document management database 330 shown in FIG. 13 is created including the association of the format ID.

  In the document management database 330 described above, the reference coordinates are rewritten by the coordinate calibration process. However, as shown in the document management database combined in the format table 802 in FIG. 15 and the association table 803 in FIG. The correction amount may be stored. In this case, the format table 802 stores the first reference coordinates and the second reference coordinates for each format ID, and the association table 803 stores the association between the sheet ID and the format ID and the correction amount for each sheet ID. Saved. Also in this example, the first reference coordinates and the second reference coordinates are the first positioning mark and the second positioning mark when there is no printing deviation in the format image. In this case, the process of step S270 in the coordinate calibration step (step S200) of FIG. 12 does not store the reference coordinates, but stores the correction amount from the reference coordinates in the association table 803. The system will be calibrated.

  In the flowchart of FIG. 12, various conditions are required to change and save the position of the reference coordinate. However, as shown in FIG. 17, the coordinate calibration process is performed after detecting a continuous tap operation. The correction of the tap position in step S260 in FIG. 12 and the saving of the position of the reference coordinate in step S270 may be executed without any particular condition.

  In the present embodiment, the code image is preliminarily printed on paper, but the code image and the format image may be printed continuously. In this case, the association between the paper ID and the format ID can be performed when continuous printing is performed.

  In the present embodiment, two positioning marks and two taps have been described as an example, but the same processing can be performed even three times or more.
