  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a control block diagram for explaining an image reading apparatus (image processing apparatus) according to the first embodiment of the present invention.

  As shown in FIG. 1, the image reading apparatus 1 includes a reading sensor 7 that reads an image of a document 2, and a first print head or the like that is disposed upstream of the reading sensor 7 in the conveyance direction of the document 2. A printing apparatus 3 and a second printing apparatus 8 such as a print head disposed downstream of the reading sensor 7 in the conveyance direction of the document 2 are provided. The image reading apparatus 1 also includes a CPU (control means) 15 that controls the entire apparatus, and a personal computer (hereinafter referred to as a PC) 30 via an I / F (interface) 17 such as USB or SCSI. Connected to external devices. Further, the image reading apparatus 1 includes a first print region setting unit 18, a second print region setting unit 19, and a duplication detection unit 16.

  The first printing device (first printing means) 3 is movable in the width direction of the document 2 along the slide shaft 4 by driving the motor 5 controlled by the CPU 15 via the motor driving circuit 14. . In the first printing apparatus 3, the home position is determined by the home position sensor 6.

  The second printing apparatus (second printing unit) 8 is movable in the width direction of the document 2 along the slide shaft 9 by driving the motor 10 controlled by the CPU 15 via the motor driving circuit 12. . The home position of the second printing apparatus 8 is determined by the home position sensor 11. Each printing apparatus is controlled by the CPU 15 via a print drive circuit (not shown).

  The reading sensor 7 is disposed between the first printing device 3 and the second printing device 8, and the image data of the read document 2 is subjected to necessary processing by the image processing circuit 13. The processed image data is output to the PC 30 via the interface 17 and displayed on the display 32.

  In the image reading apparatus 1 configured as described above, the document 2 is conveyed in the direction of the arrow A, and printing processing is performed by the first printing apparatus 3. Subsequently, the reading sensor 7 performs a reading process of the document image including the additional print information added to the document 2 by the printing process of the first printing apparatus 3. Subsequently, a printing process is performed on the document 2 by the second printing device 8. At this time, the print information printed on the document 2 is not read by the reading sensor 7, and the document 2 is discharged as it is. The

  FIG. 2 is an explanatory diagram for explaining the conveyance direction of the document 2 and the printing result.

  As shown in FIG. 2, the main scanning direction is the X direction and the sub scanning direction is the Y direction with respect to the conveyance direction of the document 2. A character string 70 is printed on the document 2 by the first printing device 3, and a character string 71 is printed by the second printing device 8. Each printing position is determined by coordinates where the upper left corner of the document 2 is the origin (X, Y) = (0, 0). The character string 70 is printed at a position indicated by coordinates (X1, Y1), and the character string 71 is printed at a position indicated by coordinates (X2, Y2). The character string 70 and the character string 71 are printed at a rotation angle position of 90 ° in FIG.

  FIG. 3 is a diagram for explaining an example of a print area setting screen displayed on the display 32 of the PC 30.

  In FIG. 3, the print area setting screen is divided into two parts: a display screen for character strings by the first printing device 3 and a display screen for character strings by the second printing device 8.

  The display screen for character strings by the first printing device 3 includes an input field 50 for character strings to be printed by the first printing device 3, an input field 51 for coordinate setting values in the X direction, and a coordinate setting value in the Y direction. An input field 52, a font size setting value input field 53, and an angle setting value input field 54 are displayed. When the user inputs a character string or a set value into these input fields from the keyboard 31 or the like of the PC 30, the input information is set in the first print area setting means 18 of the image reading apparatus 1.

  The coordinate position of the first character of the character string is determined based on the setting values in the coordinate setting value input field 51 for the X direction and the input field 52 for the coordinate setting value in the Y direction. Further, the rotation angle of the character string by the first printing apparatus 3 in FIG. 2 is set in the angle setting value input field 54 in FIG. 3, and FIG. 3 shows a case where it is set to 90 °.

  Similarly, on the display screen for character strings by the second printing device 8, the input column 60 for the character string to be printed by the second printing device 8, the input column 61 for the coordinate setting value in the X direction, and the coordinate in the Y direction. A setting value input field 62, a font size setting value input field 63, and an angle setting value input field 64 are displayed. When the user inputs a character string or a set value into these input fields from the keyboard 31 or the like of the PC 30, the input information is set in the second print area setting unit 19 of the image reading apparatus 1.

  The coordinate position of the first character of the character string is determined by the setting values in the coordinate setting value input field 61 in the X direction and the coordinate setting value input field 62 in the Y direction. Further, the rotation angle of the character string by the second printing device 8 in FIG. 2 is set in the angle setting value input field 64 in FIG. 3, and FIG. 3 shows a case where it is set to 90 °.

  Incidentally, FIG. 2 shows a case where the character string printing area by the first printing device 3 and the character string printing area by the second printing device 8 are printed without overlapping. However, in the character string display screen by the first printing device 3 and the character string display screen by the second printing device 8 shown in FIG. Therefore, there is a possibility that the print areas overlap with carelessness of the user.

  Therefore, based on the value set in the first print area setting means 18 and the value set in the second print area setting means 19, the duplication detection means 16 detects duplication of each print area.

  With reference to FIG. 4, the 1st printing area setting means 18, the 2nd printing area setting means 19, and the duplication detection means 16 are explained in full detail.

  As shown in FIG. 4, the first print area setting means 18 includes a print character count 101, an X set value 102, a Y set value 103, a font size 104, and a print character angle 105 in the first printing apparatus 3. Is set. In the second print area setting means 19, the number of print characters 111, the X set value 112, the Y set value 113, the font size 114, and the character angle 115 to be printed in the second printing apparatus 8 are set.

  On the other hand, the duplication detection unit 120 includes a first print area calculation unit 121, a second print area calculation unit 122, a comparison unit 123, and a flag register 124 that holds a flag indicating whether each print area is duplicated. The

  The first print area setting means 18 and the second print area setting means 19 are constituted by registers that can be written from the CPU 15. The set value written in the first print area setting means 18 is coordinate-converted by the first print area calculation means 121 to obtain a print area. The set value written in the second print area setting means 19 is coordinate-converted by the second print area calculating means 122 to obtain a print area.

  Then, the obtained coordinate positions are compared by the comparison means 123 to determine whether or not there is an overlapping area. As a result of the determination by the comparison unit 123, if an overlapping area exists, the flag 1 is set in the flag register 124, and if the overlapping area does not exist, the flag is set to 0.

  With reference to FIG. 5, processing examples of the first print area calculation unit 121, the second print area calculation unit 122, and the comparison unit 123 will be described.

  The first print area calculation unit 121 obtains the position of the character printed on the document 2 by the first printing apparatus 3 based on the setting value set by the first print area setting unit 18. Note that the origin (0, 0) is the upper left of the document in FIG. 5 where the document transport direction indicated by the arrow B is upward.

  The printing area 80 in the first printing apparatus 3 is indicated by an area surrounded by (a1, b1), (a1, b2), (a2, b1), (a2, b2). (A1) is equal to the X set value 102, and (b1) is equal to the Y set value 103. (A2) is obtained from a table indicating a preset size in the X direction corresponding to the font size 104 and the angle 105. (B2) is obtained from the result obtained by multiplying the value obtained from the table indicating the preset Y-direction size by the multiplier 101 with the number of characters 101 corresponding to the font size 104 and the angle 105.

  The second print area calculation unit 122 obtains the position of the character to be printed on the document 2 by the second printing device 8 based on the set value set by the second print area setting unit 19.

  The printing area 81 in the second printing apparatus 8 is indicated by an area surrounded by (c1, d1), (c1, d2), (c2, d1), (c2, d2), and each value is the first value. It is obtained in the same manner as for the printing area 80 of 1.

  When the set value of the number of print characters 101 increases in the first print area setting means 18, the print area 80 in FIG. 5 increases in the Y direction. When the X setting value 102 is increased, the print area 80 in FIG. 5 moves in the X direction. When the Y setting value 103 is increased, the print area 80 in FIG. 5 moves in the Y direction. When the setting values of the font size 104 and the character angle 105 are changed, the width of the print area 80 in FIG. 5 changes in the X direction and the Y direction in accordance with the changed font size and character angle.

  Similarly, in the second print area setting unit 110, when the set value of the number of print characters 111 increases, the print area 81 in FIG. 5 increases in the Y direction. When the X set value 112 is increased, the print area 81 in FIG. 5 moves in the X direction. When the Y setting value 113 is increased, the print area 81 in FIG. 5 moves in the Y direction. When the set values of the font size 114 and the character angle 115 are changed, the width of the print area 81 in FIG. 5 changes in the X direction and the Y direction in accordance with the changed font size and character angle.

  The comparison unit 123 compares the print area 80 and the print area 81 to determine whether there is an overlapping area. The comparison means 123 compares the coordinates with a comparator, and determines whether or not there is an overlapping region by using a logic circuit that determines whether or not the inequalities shown in the following equations (1a) to (4b) hold.

  In Expression (1a), c1 is included between a1 and a2, and d1 is included between b1 and b2 in Expression (1b). Therefore, it is determined that there is an overlapping region on the condition that both of these hold.

a1 <c1 <a2 (1a)
b1 <d1 <b2 (1b)
Similarly, when both formula (2a) and formula (2b) hold, or when both formula (3a) and formula (3b) hold, or when both formula (4a) and formula (4b) hold It is determined that there is an overlapping area.

a1 <c1 <a2 (2a)
b1 <d2 <b2 (2b)
a1 <c2 <a2 (3a)
b1 <d1 <b2 (3b)
a1 <c2 <a2 (4a)
b1 <d2 <b2 (4b)
If all four conditions in the above equation do not hold, it is determined that there is no overlapping area.

  In the present embodiment, in order to facilitate understanding, the printing apparatuses 3 and 8 during printing are described as being fixed in the X direction. When the printing apparatuses 3 and 8 that are printing are printing while moving in the X direction, the overlapping area may be determined using a logic circuit based on the movement. The duplication determination result by the comparison unit 123 is set in the flag register 124 as a flag that becomes 0 when there is no duplication and 1 when there is duplication. The CPU 15 refers to the state of the flag register 124, and when there is no overlapping area, the printing operation by the first printing device 3 and the printing by the second printing device 8 before and after the reading operation of the image of the document 2 by the reading sensor 7. Control the behavior. Further, the CPU 15 refers to the state of the flag register 124 and executes processing for avoiding duplicate printing when there is an overlapping area.

  For example, in order to avoid duplicate printing, the CPU 15 causes the display 32 on the PC 30 side to display a warning that informs the user that the print area is duplicated, and prompts the user to change the setting value. Avoid printing.

  In the present embodiment, the overlapping area is displayed on the display screen displayed on the display 32. FIG. 9 shows an example of a display screen displayed on the display 32.

  In FIG. 9, a portion for displaying a print character string, an X setting value, a Y setting value, a font size and an angle setting value, and a portion for displaying a print position on the document 2 can be simultaneously displayed on the display 32. Yes. The overlapping portion of the printing area 80a by the first printing device 3 and the printing area 81a by the second printing device 8 is highlighted as a duplication highlighting display area 90, for example, displayed in red. If the value remains as it is, the CPU 15 informs the user that duplication will occur. While the user confirms the print position on the document 2 on the display screen, the user can perform a change operation so that the set value does not cause duplication, thereby avoiding duplicate printing.

  When the user sets one print area and then sets the other print area, if the duplication detection unit 16 detects duplication of print positions, the print area setting value set by the user is set. It may be invalid. In addition, a display may be performed informing the user of the range of setting values that can be set.

  As described above, in this embodiment, when the print area by the first printing apparatus 3 and the print area by the second printing apparatus 8 are set by the user in an overlapping manner, the user is prompted before the image reading process. On the other hand, it is possible to warn that duplicate printing will occur if the set value remains unchanged. Thereby, it is possible to easily avoid that the print areas printed on the document before and after the image reading process overlap each other.

  In addition, the user can easily set the print areas of the first printing device 3 and the second printing device 8 by inputting the number of print characters, the coordinate position of the first character, the font size, and the character angle in an input field such as a display. Therefore, it is possible to easily prevent duplicate printing.

  Next, an image reading apparatus (image processing apparatus) according to the second embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a block diagram for explaining an image reading apparatus according to the second embodiment of the present invention. Note that portions overlapping or corresponding to those in the first embodiment are denoted by the same reference numerals in the drawings, and description thereof is omitted or simplified.

  In the present embodiment, the CPU 15 refers to the state of the flag register 124, and if there is an overlapping area, the CPU 15 performs printing by the second printing apparatus 8 up to a position that does not overlap the printing area by the first printing apparatus 3. The movement amount calculation means 125 calculates the movement amount S of the area. Then, the second printing apparatus 8 is moved to a position different from the position set by the user based on the calculated movement amount S, and the printing area by the first printing apparatus 3 and the printing area by the second printing apparatus 8 are moved. Avoid duplication.

  FIG. 7 is a diagram illustrating a state in which the printing area 80a by the first printing apparatus 3 and the printing area 81a by the second printing apparatus 8 overlap. In FIG. 7, the printing area 80 a by the first printing device 3 does not move, and the printing area 81 a by the second printing device 8 moves by the movement amount S in the X direction. Avoid duplication of print areas 80a and 81a.

  The movement amount calculation means 125 for calculating the movement amount of the printing area 81a by the second printing apparatus 8 is constituted by, for example, a subtractor, and when the CPU 15 refers to the state of the flag register 124 and detects an overlap, The movement amount S is calculated using 5).

S = a2-c1 (5)
In FIG. 8, the movement amount S is slightly larger than the value obtained by the above equation (5) to provide a margin.

  Then, the CPU 15 controls driving of the motor 10 via the motor driving circuit 12 based on the movement amount S calculated by the movement amount calculation means 125. The motor 10 is composed of, for example, a stepping motor, and moves the second printing apparatus 8 along the slide shaft 9 in the X direction by the number of steps corresponding to the movement amount S via a belt (not shown). Printing processing by the second printing device 8 is performed at the moving position. Thereby, it is possible to avoid the overlap between the printing area by the first printing device 3 and the printing area by the second printing device 8.

  In the present embodiment, the case where the second printing device 8 is moved with respect to the first printing device 3 has been exemplified, but instead, the first printing device with respect to the second printing device 8 is illustrated. 3 may be moved.

  Further, in the present embodiment, the case where the printing area by the second printing device 8 is moved in the X direction is illustrated, but the printing area may be moved in the Y direction. In this case, instead of moving the printing apparatus, the movement amount calculation unit 125 calculates the movement amount R in FIG. 7 and changes the print timing in accordance with the movement amount R and the sheet conveyance speed, thereby changing the print region. Move.

  Further, the moving amount and moving direction of the print area may be fixed and set, or the user may be able to set with the display 32 of the PC 30 or the like.

  Furthermore, in this embodiment, for convenience of explanation, the case where the print area of the second printing apparatus 8 is moved in the positive direction of the X axis with respect to the print area of the first printing apparatus 3 is illustrated. You may make it move to a negative direction.

  Furthermore, since the movement direction is changed in accordance with the overlap amount of the print area, if there is a large overlap in the positive direction of the X axis when viewed from the center of one print area, the other print area is moved in the positive direction. If there are many overlaps in the negative direction of the axis, the other print area may be moved in the negative direction of the X axis.

  Furthermore, in this embodiment, the case where the other print area is moved with respect to one print area has been exemplified, but both the print area of the second printing device 8 and the print area of the first printing device 3 are moved. You may make it make it.

  As described above, in the present embodiment, when the print area by the first printing apparatus 3 and the print area by the second printing apparatus 8 are set to overlap, one print area is automatically shifted. Since the printing process is performed, it is possible to easily avoid the overlapping of the print areas printed on the document before and after the image reading process without burdening the user. Other configurations and operational effects are the same as those in the first embodiment.

  In addition, this invention is not limited to what was illustrated to the said embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.

  For example, a plurality of first printing apparatuses 3 may be provided so as to avoid duplication of print areas by the plurality of first printing apparatuses 3, and a plurality of second printing apparatuses 8 may be provided to provide a plurality of printing areas. You may make it avoid the duplication of the printing area by the 2nd printing apparatus 8, Furthermore, duplication with the printing area by the some 1st printing apparatus 3 and the printing area by the some 2nd printing apparatus 8 is made. You may make it avoid.

  Further, when a printing head having a sufficient width in the width direction of the document 2 is used as each printing apparatus, printing is performed at any position within the printable range without moving the printing head. The printing area may be moved in the X direction by determining whether or not to perform the printing process.

  In the above-described embodiment, the case where the first print area setting unit 18, the second print area setting unit 19, and the duplication detection unit 16 are configured by hardware circuits is exemplified.
