[0004]

The printing section of such a composite form processing unit employs a dot impact type printing apparatus which has a relatively high follow-up capability with respect to a change in the height of a form printing surface.

However, there is a large difference between the thickness of a single sheet such as a payment slip and the passbook, and it is difficult to absorb such a difference with the margin of the printing apparatus. For this reason, when printing on a thin form, the print head pins may not reach the surface of the form, which may cause blurring of the print.On the other hand, when printing on a thick form, the print head pins may be damaged by receiving a large stress. Was. Also, when only printing on a passbook is considered, the distance between the print head pin and the form printing surface greatly changes depending on the page to be printed, and the same problem occurs.

Reference numeral 2 denotes a customer service port 1 for receiving a form such as a passbook and a single form (payment form) from a user, a capturing unit 2 for capturing a form input from the customer service port 1, and a capturing unit 2. OCR unit 3 for optically reading the image of the form taken in by the system and performing character / mark recognition, dot impact type printing unit 4 for printing on the form, and form storage unit for storing traded payment documents and the like 5, a magnetic stripe read / write unit 6 for reading / writing from / to a magnetic stripe of a passbook, a page turning mechanism 7 for turning pages of a passbook such as a 2000 passbook, and a passbook issuing unit 8 for issuing a passbook. And a print platen mechanism 90 for optimizing the distance between the print head pins of the print unit 4 and the form printing surface.

Next, the flow of the payment processing on the ATM 100 will be described. Depending on the user, composite form processing unit 1
When a payment note is inserted from the customer service port 02 of the customer, the payment section 2 automatically takes in the payment note. The received payment form is transported as it is so as to pass through the reading position of the OCR unit 3, and at this time, the image of the payment form is O
It is read by the CR unit 3. Thereafter, the payment form is transported between the printing unit 4 and the printing platen mechanism 90 to the temporary storage unit 10 immediately before the form storage unit 5, and is stored there.

On the other hand, the payment document image read by the OCR unit 3 is passed to a recognition process, and as the recognition result, transaction data such as the account number of the payment destination and the payment amount written in the payment document are obtained. The data as the recognition result is displayed on the operation panel 105 together with the image of the payment note. Then, the user compares each information to confirm whether the recognition result is correct, and if correct, the operation panel 10
5. Press the confirmation key above. When the confirmation key is pressed, the user is instructed by a screen or voice message to insert a bill into the bill unit 103, insert a coin into the coin unit 104, and insert a card into the card unit 101. Transactions such as payment to an account are performed.

Here, in order to carry out the settlement using a passbook, when a passbook is inserted from the customer service port 1, a magnetic stripe read / write is performed.
The write section 6 reads information such as the user's account number from the magnetic stripe of the passbook. Transactions such as payment from the user's account to the payment destination account are performed based on the acquired information.

The magnetic stripe records information such as the last transaction date, account balance, and a new book page number in addition to the account number. Here, the new book page number is information indicating from which page the book should be started next.

When the transaction is completed, the OCR section 3 reads a page mark, which is printed at a fixed position on each spread page of the passbook, and expresses the page number in a unique pattern, and reads this page number on the magnetic stripe read / write. The unit 6 determines whether the new page number matches the new page number read from the magnetic stripe of the passbook. If they match, it is determined that the spread page of the current passbook is correct, and the passbook is moved to the print position of the print unit 4.

If the page numbers do not match, for example,
The passbook is returned to the customer service port 1, and the user is instructed by a screen or voice to open a correct page and reinsert the passbook. Thereafter, the pass / fail of the spread page of the passbook is determined again in the same procedure, and if it is confirmed that the correct page is opened, the passbook is moved to the printing position. However,
When the passbook is the 2000 passbook, the page turning mechanism 7 automatically turns the page to the correct page.

Here, the spread pages of the passbook refer to both left and right pages or both upper and lower pages appearing when the passbook is opened. The passbook page number may be assigned to each double-page spread or may be assigned to each double-page spread.

Subsequently, the printing unit 4 prints (records) the transaction result on the first blank line of one of the left, right, upper and lower pages of the two-page spread of the passbook. After the entry, the passbook is returned to the read / write position of the magnetic stripe read / write unit 6, where the information of the magnetic stripe is rewritten to the latest content, and then returned to the customer service port 1 via the import unit 2. .

After the passbook is returned, the payment form is moved from the temporary holding unit 10 to a printing position by the printing unit 4, where information such as the date and time of handling the payment form and the handling office are printed. Thereafter, the payment form is transported to the form storage unit 5 and stored therein.

Next, details of the print platen mechanism 90 of the composite form processing unit 102 will be described. FIG. 3 is a side view of the printing unit 4 and the printing platen mechanism 90, and FIG. 4 is a plan view of the printing platen mechanism 90.

In these figures, reference numeral 91 denotes a print platen, which is arranged so as to face the print head pin 4a with the form P interposed therebetween. The height of the print platen 91, that is, the distance from the print head pin 4a is set to, for example, 0.1 by driving the pulse motor 92.
It can be changed at a fine pitch of about mm. Reference numerals 93 and 94 denote a worm wheel 93 and a worm gear 94 for converting the rotation of the drive shaft 92a of the pulse motor 92 into the elevating movement of the printing platen 91, respectively. The worm wheel 93 is coaxially fixed to the drive shaft 92a of the pulse motor 92. The worm gear 94 is provided integrally with a platen support member 95 that supports the print platen 91.

The printing platen 91 is provided with an elastic member 9 such as a coil spring on the upper end of a platen supporting member 95 which can be moved up and down.
6 is supported. The elastic member 96 is for reducing the printing pressure applied to the form P on the print platen 91 so as to prevent the thin form such as a payment form from being bent or wrinkled.

As shown in FIG. 4, the print platen mechanisms 90 are arranged in a line in a direction orthogonal to the form transport direction in a row of three machines, and a form is placed on these three print platens 91. I have. The heights of these three print platens 91 are individually controlled.

The print platen mechanism 90 is provided with an optical sensor 97 for detecting the initial position of each print platen 91. FIG. 3 shows a state in which the print platen 91 is at the initial position.
The height of the surface 1 coincides with the height of the transport path 11. This height is also the height when the form P is simply passed between the printing unit 4 and the printing platen mechanism 90.

Next, a description will be given of a means for determining the type of a form entered by a user.

The type of the form is determined using, for example, a group of sensors arranged near the taking-in section 2. In FIG.
The sensor arrangement near such an intake unit is shown. As the sensor, for example, a light transmission type sensor or the like is used. The role of each sensor is as follows.

SC01 is a sensor for detecting the left end of the payment form (with stub) Pa. SC02 is a sensor for detecting the right-aligned state of the inserted medium. S
C03 and SC04 are sensors for detecting the presence or absence of the inserted medium and for detecting the skew of the passbooks Pb and Pc.
SC05 and SC06 are sensors for detecting the skew of the payment note (with a stub) Pa. SC07 is payment form P
This is a sensor for detecting the maintenance hole a. SC08 and SC
Reference numeral 09 denotes a sensor for detecting the skew of the payment note Pa and for determining the vertical / horizontal passbook Pa and the 2000th passbook Pc. And SC10 is a vertical / horizontal passbook Pa and 20.
This is a sensor for measuring the length of the No. 00 passbook Pc.

Next, the configuration of the mechanism control unit of the composite form processing unit 102 of the present embodiment will be described. FIG. 6 shows the configuration of the mechanism control unit.

As shown in FIG. 3, the system board 41 of the composite form processing unit 102 includes a CPU board 43,
A data processing board 44, I / O ports 45 and 46, etc. are mounted, and these communicate with each other through an internal bus 47. The CPU board 43 can communicate with the general control unit 42 of the ATM 100.

The data processing board 44 performs read / write data processing by the magnetic stripe read / write unit 6 and performs processing for generating print pattern data of the printing unit 4. The magnetic head driver board 48 drives the magnetic head 49 of the magnetic stripe read / write unit 6 based on the recording data for the magnetic head generated by the data processing board 44, and the magnetic head 49 converts the magnetic stripe of the passbook into a magnetic stripe. The read signal is processed.

The print drive board 50 drives the print head pins 4a of the print unit 4 based on the print pattern data generated by the data processing board 44.

The OCR section 3 is connected to the I / O port 45 of the system board 41, and another I / O port 46
A driver board for supplying drive signals to power sources such as various motors and solenoids, including the pulse motors 92 of the print platen mechanism 90, and monitoring the outputs of the sensor SC01-10 and the platen initial position detection sensor 97. 52 are connected. The detection signals of the sensors SC01 to SC10 obtained by the driver board 52 are I / O
The data is sent to the CPU board 43 through the port 46 and the internal bus 47.

Next, a process for optimizing the distance between the print head pin 4a and the form printing surface in the composite form processing unit 102 will be described. FIG. 7 shows the flow of this processing.

However, prior to this processing, the CPU determines the type of the form (horizontal passbook / vertical passbook / 2000 passbook / payment note) based on the outputs of the sensors SC01-SC10 near the capturing section, and determines the form. Is a passbook, the page to be printed of the passbook is determined, and the results of these determinations are held.

It is assumed that the initial position of the print platen 91 coincides with the transport surface of the transport path 11. In addition, a table in which information of the platen control amount for each form type needs to be prepared in advance as a table to be referred to in this processing. In the case of a passbook, the platen control amount for each page is registered in a table. The platen control amount is represented by the number of drive pulses supplied to the pulse motor 92, and the platen control amount of one drive pulse is equal to or less than the thickness of the thinnest form (payment note) processed by the composite form processing unit, for example, 0.1 mm. Set to about.

When the form is set on the print position, that is, on the print platen 91 (step 601), processing for optimizing the distance between the print head pin 4a and the form print surface is started. Hereinafter, the print head pin 4a is set for each form type.
The flow of processing for optimizing the distance between the document and the form printing surface will be described.

(Process of Horizontal Passbook) When the form is a horizontal passbook, the CPU obtains a platen control amount corresponding to a print target page (upper or lower spread page) of the horizontal passbook from the table (step S1). 604,61
0) A drive pulse is supplied to each pulse motor 92 so as to move each print platen 91 from the initial position by the acquired platen control amount.

As shown in FIG. 8, in the case of a horizontal passbook, spread pages (upper / lower pages) of the passbook are arranged in the transport direction. In this case, if attention is paid to each page, the distance between the page surface and the print head pins 4a is uniform over the entire page. Therefore, the table only needs to set a common platen control amount between the print platens for each page for the horizontal passbook.

Thus, in the case of the horizontal passbook, each print platen 91 is commonly moved from the initial position by a control amount corresponding to the page to be printed (step 60).
5,611), and the distance between the print head pin 4a and the print surface can be optimized over the entire page.

If the print processing is performed from the upper page of the horizontal passbook (step 606), and there is no empty line in the upper page and the print processing is shifted to the lower page (step 607), the lower page of the spread of the passbook is used. Is set at the printing position (step 609), the platen control amount corresponding to the lower page is obtained from the table (step 610), and each printing platen 91 is commonly moved from the initial position by the obtained platen control amount. (Step 611),
Print processing may be performed (step 612).

After the printing process, each printing platen 91 is returned to the initial position (Step 608). (Processing of No. 2000 Passbook) As shown in FIG.
In the case of the number passbook, the spread pages (upper page / lower page) of the passbook are arranged in the transport direction as in the case of the horizontal passbook, so the procedure is the same as that of the horizontal passbook. However, since the correspondence between the page and the platen control amount is different from that of the horizontal passbook, a table showing the correspondence between the page and the platen control amount is prepared in advance for the 2000th passbook, and the printing page is referred to by referring to this table. Must be obtained for the platen control amount.

(Process of Vertical Passbook) As shown in FIG.
In the case of a vertical passbook, each page of the spread of the passbook (left page /
(Right page) are simultaneously placed on the three print platens 91. If there is a large difference in the thickness of each spread page, each print platen 9 is adjusted to one of the smaller thickness pages.
When the height of the print head 1 is set to be the same, as shown in FIG. 11, for example, the overall height is raised by the thicker page surface, and the distance between the print surface and the print head pin 4a deviates from the optimum range. There is a risk that it will. Therefore, with regard to the vertical passbook, the heights of the individual print platens 91 are individually controlled so that the distance between the print surface and the print head pins 4a falls within the optimum range over the entire left and right pages.

FIG. 12 shows an example of control for each printing platen 91. Since the left and right thicknesses of the vertical passbook can be known from the facing pages, the platen control amounts such that the distance between the print head pin 4a and the printing surface of each of the left and right pages falls within the optimum range are determined based on the thickness. The control amount of the print platen 91 is set in a table. Central printing platen 9
For example, an average value of each of the left and right platen control amounts is set as the one control amount.

From such a table, a platen control amount for each print platen 91 associated with a spread page of a vertical passbook is obtained (step 613), and each print platen 91 is moved from its initial position. As a result (step 614), the distance between the print head pin 4a and the print surface can be kept within the optimum range over the entire left and right pages.

(Payment Form (Single Form) Processing) The platen control amount in the case of the payment form is set as a constant value in the table, and each print platen 91 is commonly moved from the initial position by the constant control amount. (Step 6
16,617), and the distance between the print head pin 4a and the print surface can be optimized.

By the way, when a single form (payment note) is printed,
Deformation such as bending or wrinkling is likely to occur due to local printing pressure received from the print head pin 4a. So Figure 3
As shown in (1), the print platen 91 is supported on the platen support member 95 via an elastic member 96 such as a coil spring. Since the printing pressure applied to the form P on the printing platen 91 is relieved by the elastic support of the printing platen 91, it is possible to suppress the occurrence of bending or wrinkling on a single form (payment note).

Thus, according to this embodiment, the horizontal passbook,
In printing on various types of forms such as a vertical passbook, a 2000 passbook, and a payment form, the distance between the print head pin 4a and the print surface can be optimized. Accordingly, it is possible to prevent print fading caused by an excessively wide distance between the print head pins 4a and the printing surface, and conversely, damage to the print head pins caused by the distance being too close, thereby improving print quality. Stability and reliability can be improved.

Also, the height of the plurality of printing platens 91 can be individually controlled, so that the distance between the printing head pins 4a and the printing page surface can be set to an optimum range over the entire left and right pages of the vertical passbook. Can be set.

It should be noted that the form processing apparatus of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention.

For example, the number of printing platens is not necessarily three.
There is no need to be two, and two or four or more may be used. Further, in the above-described embodiment, the plurality of print platens are arranged side by side in the direction orthogonal to the form transport direction, but may be arranged in the form transport direction. In this case, the control amount of each print platen may be individually controlled when printing on a horizontal passbook and a 2000 passbook, and the control amount of each print platen may be commonly controlled when printing on a vertical passbook.

[0056]

As described above, according to the present invention,
Various types of forms including passbooks and single forms can be stably printed with high quality, and damage to the print head pins can be prevented.

According to the present invention, the positions of a plurality of print platens constituting one print platen as a whole are individually controlled. For the type of passbook, the distance between the form printing surface and the print head can be optimized.

Further, according to the present invention, the adoption of the elastic support structure for elastically supporting the printing platen can suppress the occurrence of bending or wrinkling in printing on a cut sheet such as a payment slip.
