Abstract

PROBLEM TO BE SOLVED: To solve a problem that the forward end of each page is not aligned because of a binding part when a bankbook having the binding part orthogonal to the carrying direction is carried, and a problem that the results of transaction are printed on a rule previously printed on the bankbook. SOLUTION: A decision is made whether the open page of a bankbook is printed or not (S16) and if a page to be printed is opened, the bankbook is carried up to a position where the center of a finally printed line faces a CCD (S17). The bankbook is carried furthermore by an amount corresponding to one pulse (S19) and a decision is made whether a rule previously printed on the bankbook can be detected or not (S20). If it can be detected, the bankbook is carried by an amount corresponding to the number of pulses required for bringing the part of the bankbook directly under the CCD to the center of a print head with reference to that position (S21). If a previously printed rule cannot be detected at S20, the control returns back to S19.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a booklet printing apparatus that conveys and prints in a state where the longitudinal direction of the binding portion of the booklet is parallel to the longitudinal direction of the platen.

[0002]

2. Description of the Related Art When a passbook, which is a booklet, is inserted into the apparatus through an insertion / ejection port, the passbook binding portion is inserted parallel to the insertion / ejection port, that is, in a direction orthogonal to the carrying direction. The leading edge of the passbook is detected by a sensor provided in the vicinity of the insertion / ejection port, and the conveyance control thereafter is managed by the number of conveyance pulses from the leading edge of the passbook. The conveyance control is based on the front end of the cover sheet, and the same conveyance control is performed assuming that the front end of the opened page coincides with the front end of the cover sheet regardless of the page.

When the passbook sucked from the insertion / ejection port is conveyed above the magnetic signal reading unit, the conveyance is stopped, and the previous last line print information stored in the magnetic stripe provided on the back cover of the passbook. Is read out, and the carry amount is determined based on the print information of the last line of the previous time, and the line is conveyed so that the line next to the last line of the previous time comes just below the print head. In calculation, the transaction result is printed between the ruled lines that are printed in advance on the passbook.

[0004]

By the way, since the cover of the passbook is a stiff paper, when the passbook is opened with a predetermined double-page spread and sucked through the insertion / ejection port, a bulge occurs due to the stiffness of the cover. The portion of the paper inside the passbook that prints the transaction results, called the middle paper, may also bend. When the inside paper bends, the ruled line interval of the passbook becomes shorter than the design value in the carrying direction, and as a result, the carrying is carried more than necessary. If the amount of bending is small, the transaction result can be printed between the ruled lines, but if the amount of bending is large, the amount of conveyance will be too large and the transaction result will be printed on the ruled line, which is visually preferable. Absent.

Further, the longitudinal direction of the binding portion of the passbook used is conveyed to the print head in a direction orthogonal to the conveying direction. Since the central part of the passbook is pushed by the binding section, the leading edge of each inside paper does not coincide with the leading edge of the cover sheet, and the leading edge of the inside paper is displaced to the upstream side in the transport direction with respect to the leading edge of the cover sheet, that is, the side opposite to the print head . The larger the number of inner sheets to be overlaid on the cover sheet, the larger the deviation.

Further, if the entire passbook is composed of 24 pages, for example, when printing the latter half of pages 14 and subsequent pages, printing is performed on the middle paper folded back around the binding section, so that the resistance by the binding section is increased. Becomes larger and the gap from the cover increases. The conveyance control is based on the front edge of the cover, and the same conveyance control is performed assuming that the front edge of the opened page is the same as the front edge of the cover regardless of the page, so the transaction results There is a greater possibility that the print will be printed across the ruled lines.

Next, the control for printing the passbook 60 will be described with reference to FIG.

First, the passbook 60 is bound to the insertion / ejection slot 2 by the binding portion 61.
The longitudinal direction of is inserted in a direction orthogonal to the transport direction. At this time, it is desirable to insert the page for printing the passbook 60 in an open state. When the passbook is inserted into the insertion / ejection port 2, the sensor 41 arranged near the insertion / ejection port 2 is turned on, and the passbook 60 is inserted into the insertion / ejection port 2 in step 11 (hereinafter referred to as S11). ) To recognize. S1
When it is recognized that there is a passbook in 1, the conveyance roller pair is nipped and the shutter is opened, and the conveyance motor 28 starts to be driven. When the conveyance motor 28 starts to drive, the passbook 6
0 is incorporated into the passbook printer 1, and if the passbook 60 is tilted by the passbook posture correction unit 5, the correction solenoid 47
Drive to correct the inclination or posture of the passbook 60,
The passbook 60 is transported to directly above the unit 6 by a predetermined number of steps, and the transport motor 28 is transported and stopped (S12).

Next, the previous last print line information recorded on the magnetic stripe provided on the back cover of the passbook 60 is magnetically read through the magnetic head 30 (S13). When the final print line information is read, the carry motor 28 is carried again,
The page mark 68 is driven right below the CCD 14 and driven for a predetermined number of steps to stop (S14). When the carry motor 28 is stopped, the second light source 17 is caused to emit light and the information received by the CCD 14 is optically read (S
15). The page information read in S15 is the magnetic head 30.
It is determined whether or not the page information is read through (step S16). If it is determined in S16 that the optically read information and the magnetically read information match (Y in S16), the number of pulses corresponding to the final print row is conveyed. At this time, the number of pulses is the sum of the number of pulses corresponding to the print center of the first line of the page in the transport direction from the page mark reading position and 24 times the number of lines. In the present embodiment, the interval between ruled lines 62 is set to 24 pulses. When the print has been carried to the print center in the carrying direction of the last print line, the first light source 16 is subsequently turned on and the 11-pulse carry (S18) and the 1-pulse carry (S19) are continuously performed. Next, it is determined whether the ruled line 62 can be detected via the CCD 14 (S20). Since 12 pulses are carried in S18 and S19, the ruled line 62 next to the last printed line comes directly below the CCD 14 in the designed value. If the ruled line 62 cannot be detected in S20 (N in S20), it is determined that the predetermined amount cannot be conveyed due to a conveyance error, the process returns to S19, and after one pulse is conveyed, it is determined again whether the ruled line 62 can be detected via the CCD 14. . S19 and S20 until ruled lines can be detected
repeat.

If the ruled line 62 can be detected in S20 (Y in S20), the carry motor 28 carries a predetermined number of pulses so that the current print start line is carried directly below the print head 24 ( S21). Here, the predetermined number of pulses is 12 from the interval between the position of the passbook 60 directly below the CCD 14 and the position directly below the center of the print head 24 from the position of the CCD 14.
It is the number of pulses after subtracting the number of pulses. When the passbook 60 is conveyed to a predetermined position where it is printed, the transaction result information transmitted from the outside via the I / F 51 is output using the print head 24 (S22). If there are multiple transaction results at this time, 2 after outputting one transaction result
After carrying 4 pulses, the next transaction result is printed, and this is repeated to print all the transaction results.

When all the transaction results have been printed out, the passbook 60 is conveyed backward to the position immediately below the CCD 14 at which the last line printed is turned on, the second light source 17 is turned on, and the last printed line is printed. Read the print density of information (S2
3). If the print density read in S24 is equal to or higher than the predetermined value (Y in S24), the passbook 60 is conveyed again in the reverse direction and returned to the insertion conveyance port 2 to end the processing (S25). The discharging process of S25 for returning the passbook to the insertion / ejection slot 2 also includes a process of magnetically writing the last print line information of this time on the magnetic stripe on the back cover of the passbook. If it is determined that the print density read in S24 is lower than the predetermined value (N in ST24), a guidance display is displayed to replace the ink ribbon provided in the passbook printer 1 (S26). When the guidance display is displayed, the discharging process of S25 is performed.

If it is determined in S16 that the correct page is not opened, a series of page turning processing (S27) is performed. The page turning process in S27 includes the following processes. First, the switching section solenoid 49 is switched so that the passbook 60 can be conveyed to the auxiliary passbook conveyance path 11 and the passbook 60 is conveyed in the reverse direction and moved to the page turning section 13. Next, when the passbook 60 is conveyed to the passbook turning portion 13, the page turning motor 45 is driven to pass the passbook 6
When the page read by the magnetic head 30 is opened and the page read by the magnetic head 30 is opened, the passbook 60 is passed through the auxiliary passbook transport path 11 and the passbook 60 is placed on the passbook transport path 4. When it returns, the switching unit solenoid 49 is returned. When the page turning process S27 is completed, the process of S17 is performed.

In the present embodiment, since the ruled line 62 of the passbook 60 is used as a reference, even if the passbook is printed on the passbook provided with the binding portion 61 in the direction orthogonal to the transport direction, the bending of the middle paper is prevented. It is possible to prevent misalignment due to the printing and printing misalignment due to overlapping of the inner sheets, and it is possible to print at a desired position between the ruled lines.

In the present embodiment, the CCD 14 has a function of reading the density of the printed characters and a function of reading the page mark in addition to recognizing the ruled line position, so that the apparatus can be downsized.

In the present embodiment, the area where the ruled line is read is read by the print head 24.
By always reading only the ruled lines, the ruled lines can be detected reliably. Further, since the part which is not printed is read, it is not necessary to provide a special mark for reading the ruled line, and therefore the passbook to be used looks good.

In the present embodiment, the ruled line 62 of the passbook 60 used is green, and the print density and page mark are black information. Since the light source for reading the black information has the same color as the ruled line, the information read by the CCD 14 cannot be read because the ruled line has the same color, and the black information can be reliably read.

Although the ruled line 62 of the passbook is described as green in the present embodiment, the color of the ruled line 62 may be red and the color of the second light source 17 may be red. Color selection is possible. The color of the ruled line and the color of the second light source 17 may be the same. In other words, the wavelength or frequency of the light reflected from the ruled line and the light emitted from the second light source 17 may be the same. On the contrary, it is essential that the color of the ruled line and the color of the first light source 16 are different, and the wavelength and the frequency must be largely different. The term “greatly different” here means that there is a difference in recognizing different colors rather than similar colors when recognizing the colors. Since the ruled line can be recognized as a color, the first light source 16 may of course be an infrared ray as described in the present embodiment.

In the present embodiment, the first light source 16 is provided directly below one end of the lens, and the LEDs of the second light source 17 adjacent to the first light source 16 are provided at equal intervals and are directly below the other end of the lens. Since they are continuously provided, even if the frequencies of the first and second light sources 17 are different, the ruled lines and the print density can be reliably read without adversely affecting the respective intended functions. .

In this embodiment, the first and second light sources are LE
Although D or the like is used, a color cellophane may be wound around the fluorescent tube to form a two-color light source, but this is not preferable because the image sensor unit becomes large.

Although the image sensor unit is fixedly provided in the present embodiment, the present invention is not limited to this, and the image sensor unit may be of a movable type.
When the image sensor unit is fixed, the fixed type is superior because there is no conveyance error in the rattling when the unit is conveyed.

In the present embodiment, the position for first determining whether or not there is a ruled line is the theoretical position of the ruled line, but the position is not limited to this. You may go before the upper ruled line. Further, the ruled line 62 is detected for each pulse in S19 and S20 of the present embodiment, but the invention is not limited to this. Passbook
If the thickness of the ruled line 62 is sufficiently large with respect to the carry amount of one pulse, the detection may be performed every plural pulses. The detection for every plural pulses has an effect of shortening the time for finding the ruled line position.

In the present embodiment, the wire dot type print head has been described, but the present invention is not limited to this, and an ink jet type print head may be used.
When an inkjet printhead is used, the passbook support plate arranged on the side opposite to the printhead with respect to the passbook is defined as a platen.
