In the transport means such as the tape printing mechanism 45 and the image capturing device 9, in order to determine the feed resolution, a reference distance X and a basic line number Lc that is a theoretical feed number up to the reference distance X are set in advance. By adjusting the reference distance X and the basic line number Lc, the conveyance distance is adjusted to a desired value. However, the transport means may cause a deviation between the reference distance X and the number of basic lines Lc. The position reached by transporting the number of basic lines Lc and the position when the reference distance X is actually measured. May be different. The conveyance rate refers to a numerical value obtained by dividing the basic line number Lc by the theoretical number of lines (Lx) necessary to send a document or the like to a predetermined position when the reference distance X is actually measured. In this embodiment, the reference distance X is set to 100 mm, the basic line number Lc is set to 800, and the printing tape 31 is fed by 1/8 mm by the operation of one line as described above.

  Hereinafter, the image data correction function will be described. 4 is a flowchart for calculating the printing-side conveyance rate Pr, FIG. 5 is a front view of the reference tape 61, and FIG. 6 is a table showing the relationship between the conveyance rate and specific marks. These are the flowcharts for calculating the image capture side conveyance rate Sr.

  First, a method for calculating the printing-side conveyance rate Pr will be described. As shown in FIG. 4, the control means executes a reference tape printing process (step S101) for printing the reference tape 61 as a reference medium on which a predetermined reference print pattern is printed as a reference medium printing means. As shown in FIG. 5, the reference print pattern of the reference tape 61 includes an arrow 65 indicating the transport direction printed in the vicinity of the printing start side end, and a reference mark 66 printed perpendicular to the transport direction. The theoretical mark 67 printed at the position reached by the line operation of 800 times that is the basic line number Lc of the printing-side conveying means from the reference mark 66, and a plurality of adjustment marks printed at equal intervals before and after the theoretical mark 67 68, the theoretical mark 67 is given the symbol “F”, the adjustment mark 68 is given the symbols A to E in order from the reference mark 66 side, and the F of the theoretical mark 67 G and H are attached to each other.

  In the reference tape printing process (step S101), when the reference tape 61 is printed, the user measures a point of 100 mm, which is the reference distance X from the reference mark 66 of the reference tape 61, using a ruler or the like. A specific mark 69 that is a line located at the reference distance X is specified from the adjustment mark 68 or the theoretical mark 67. In other words, if there is no deviation in the printing-side conveying means, the specific mark is the theoretical mark 67, and if the distance for each line is long, the adjustment marks 68 of A to E become the specific mark 69, and one line If each distance is short, the G and H adjustment marks 68 become the specific marks 69. In FIG. 5, C is a specific mark 69 as an example.

  As the specific mark information acquisition means, the control means displays a screen for inputting the code of the specific mark 69 specified by the user on the display means, and acquires the specific mark information by causing the user to input the code of the specific mark 69. The specific mark information acquisition process (step S105) is executed. Next, the control means executes a specific mark line number calculation process (step S110) for calculating the theoretical line number Lx up to the specific mark 69, and the basic line number Lc is set up to the specific mark 69 as a printing-side conveyance rate calculation means. A printing side conveyance rate calculation process (step S115) for calculating the conveyance rate of the printing side conveyance unit by dividing by the theoretical line number Lx is performed. Note that the symbols A to H of the specific mark 69 and the conveyance rate in the printing-side conveyance means have a relationship as shown in the table of FIG.

  Next, a method for calculating the image capture side conveyance rate Sr will be described. When the reference tape 61 is inserted into the image capture device 9 according to the arrow 65 and image capture is started, the control means controls the image sensor 47 of the image capture device 9 as shown in FIG. A reference mark detection process (step S151) for detecting 61 reference marks 66 is executed, and a screen for allowing the user to input the code C of the specific mark 69 specified when calculating the printing-side conveyance rate Pr is displayed on the display means. Then, a specific mark information acquisition process (step S155) for acquiring information on the specific mark 69 by causing the user to input the code C of the specific mark 69 is executed.

  And a control means performs the line number count process (step S160) which counts the line number Ls to the specific mark 69 acquired by the specific mark information acquisition process with a line counter. In this line number counting process (step S160), the specific mark 69 is specified based on the information on how many marks are the specific marks 69 after passing the reference mark 66. That is, when the image capture of the reference tape 61 is started, a point that changes from black to white is recognized as the reference mark 66, and thereafter it is recognized as having passed the mark every time it changes from black to white. When the order comes, the number of lines Ls from the reference mark 66 to the specific mark 69 is counted. Then, after the line number counting process (step S160), the control unit divides the basic line number Lc by the line number Ls up to the specific mark 69 as image capture side transport rate calculation unit. An image capturing side conveyance rate calculation process (step S165) for calculating the conveyance rate of the means is executed.

  Next, correction when an image captured by the image capture device 9 is printed by the tape printing mechanism 45 will be described. The control means executes an image data storage process (step S201) for storing the image data taken in by the image taking means in the storage means, and 1 / (printing-side conveyance rate Pr × image take-in) as the correction magnification calculating means. A correction magnification calculation process (step S205) for calculating the correction magnification Hr of the captured image data calculated by the side conveyance rate Sr) is executed. Further, the control means executes an image correction process (step S210) for correcting the image data stored in the RAM 43 in the transport direction according to the correction magnification Hr calculated in the correction magnification calculation process (step S205) as the image correction means. . Then, the control unit controls the printing unit to execute the printing process (step S215) according to the image data corrected in the image correction process (step S210).

  In this way, by correcting the length of the captured image data in the feed direction and printing, for example, the image capture side transport rate Sr is set to 80%, the print side transport rate Pr is set to 90%, and the length in the longitudinal direction is set. When a document having a length of 100 mm is captured and printed, if the image data is printed without correction, the length of the printed material in the longitudinal direction is 100 mm × 0.8 × 0.9 = 72 mm. However, when the correction magnification Hr = 1 / (0.8 × 0.9) is calculated and the conveyance direction of image data such as a bitmap that is 80 mm due to the image capture side conveyance ratio is multiplied by the correction magnification Hr, The image data becomes 111.1 mm, and printing using this image data makes it possible to print at a value close to 100 mm, which is 111.1 × 0.9 = 99.9 mm, which is an actual size of the original document.

  According to the present invention, the reference tape 61 as a reference medium having a predetermined reference print pattern is printed, and the print-side conveyance rate Pr and the image capture-side conveyance rate Sr are calculated using the same reference tape 61. By calculating the correction magnification Hr of the image captured by the image capturing device 9 from the result and correcting the longitudinal length of the image data, the longitudinal length of the document captured by the image capturing device 9 is The longitudinal lengths of the printed matter printed by the tape printing mechanism 45 can be made substantially equal.

  In addition, by forming the reference print pattern of the reference tape 61 from the reference mark 66, the theoretical mark 67, and the adjustment mark 68, the conveyance rate can be easily increased by simply measuring the reference distance X from the reference mark 66. Can be calculated.

  Further, the printing side conveyance rate calculation means calculates the theoretical line number Lx up to the specific mark 69 and divides the basic line number Lc by the theoretical line number Lx up to the specific mark 69 to calculate the printing side conveyance rate Pr. Therefore, the conveyance rate can be easily calculated, and image correction can be easily performed without incorporating an expensive CPU 41 or the like.

  Further, the image capturing side conveyance rate calculating means counts the number of lines Ls from the reference mark 66 to the specific mark 69, and divides the basic line number Lc by the counted number of lines Ls. Since the conveyance rate Sr is calculated, the conveyance rate can be easily calculated by the same calculation as the printing-side conveyance rate calculation means, and image correction can be easily performed without incorporating an expensive CPU 41 or the like.

  In the tape printer 1 described in the present embodiment, the printing side conveyance rate Pr and the image capture side conveyance rate Sr are calculated using the reference tape 61 as the reference medium, and the correction magnification Hr is calculated and loaded. Although it is configured to correct image data, it is an apparatus provided with both an image capturing device and a tape printing mechanism, and if the printing side conveying means and the image capturing side conveying means are independent, In any device, the same printing method as that of the reference tape 61 can be used, and the same operation and effect can be obtained by using a sheet or the like on which the reference print pattern is printed as a reference medium.

  In other words, each processing described in the present embodiment is applied to various apparatuses as a program that can be executed by a computer, for example, written in a storage medium such as a magnetic disk, an optical disk, or a semiconductor memory, or transmitted through a communication medium. Thus, the present invention can be applied to various devices. In this way, each process described in this embodiment is stored in a desired storage medium, and the program is executed by another computer or the like, so that the length is adjusted in the same manner as in the case of using the tape printer 1 of this embodiment. Can be easily performed.
