[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite processing apparatus such as a check processing apparatus having a print head and a scanner and a control method thereof.

[0002]

2. Description of the Related Art In recent years, printers equipped with print heads have been
It has been proposed to add a processing device such as a scanner to perform complex processing. For example, in a complex processing device equipped with a print head and a scanner, transactions are performed by printing necessary information on a check, scanning a printed check, and transmitting a scanned image to a clearing house if necessary. Enables online payment of checks using electronic content data.

By the way, in the above-described composite processing apparatus, it is necessary to suppress the floating of the print medium with respect to the scanner in order to ensure the quality of the scanned image. Therefore, it is desirable to provide a pressure feed roller at a position facing the scanner to convey the print medium while pressing the print medium against the scanner.

[0004]

However, in the case where the above-mentioned pressure feed roller is provided, when the leading edge of the print medium plunges between the scanner and the pressure feed roller, a jam may occur due to the print medium being caught. There is a
In particular, when the print medium is in a bad state (curling, bending, missing, etc.), there is a disadvantage that the occurrence rate of jam becomes high.

Further, in the composite processing apparatus, the front end of the print medium may reach the pressure feed roller position before the other processing (printing process, magnetic character reading process, etc.) is completed, so that the pressure feed roller is not supported. If the feed pitch is deviated due to the print medium being caught, there is a possibility that the processing accuracy in other processing may be reduced or the processing may be defective.

An object of the present invention is to provide a scanner at a position facing each other.
A composite processing apparatus that includes a pressure feed roller that conveys a print medium while pressing it against a scanner, but that can prevent jamming of the print medium from the pressure feed roller and prevent jamming and deviation of the feed pitch. It is to provide a control method.

[0007]

In order to achieve the above-mentioned object, a composite processing apparatus of the present invention comprises a conveying path for guiding a print medium,
A print head that is arranged along the conveying path and prints on the print medium, a scanner that is arranged along the conveying path, and scans the print surface of the print medium, and is arranged at a position facing the scanner. A pressure feeding roller that conveys the print medium while pressing it against the scanner, and a roller retracting mechanism that retracts the pressure feeding roller from the scanner to open the transport path are configured.

Further, it is preferable that the end portion of the print medium ejected by the pressure feed roller is held by a vertical conveying path on the downstream side of the pressure feed roller. In this case, since the ejected print medium is held by using the downstream vertical transport path of the pressure feed roller, the number of parts is reduced and the structure is simplified as compared with the case where a dedicated holding member is provided. be able to.

Further, it is preferable that the focus position of the scanner is offset to the upstream side or the downstream side of the conveyance with respect to the scanner contact position of the pressure feed roller. In this case, since the pressing force of the pressure feed roller does not act on the focus position of the scanner, the amount of ink attached to the scanner focus position can be reduced in the scan after printing, and as a result, the scan image due to the ink attachment can be reduced. It is possible to prevent deterioration of the quality of the product as much as possible. Also,
When the offset direction is the downstream side of conveyance, the scannable area on the leading end side of the print medium can be widened.

Further, the roller retracting mechanism comprises a rotating member for advancing and retracting a support shaft of the pressing and feeding roller with respect to the scanner, and an urging means for urging the rotating member in the printing medium pressing direction. It is preferable to include a solenoid for retracting the rotating member against the urging force of the urging means, and a drive system provided on the rotating member for driving the pressure feed roller. In this case, it is not possible to make the roller retraction mechanism compact by supporting the pressure feed roller so that it can advance and retreat by the rotating member, and the advancing and retracting operation can be smoothed. Since the drive system of the pressure feed roller is provided, the power transmission to the pressure feed roller can be reliably performed.

Further, it is preferable that the roller retracting mechanism is arranged between a pair of the pressure feed rollers provided on the support shaft. In this case, since the pair of pressure feed rollers are biased substantially evenly, it is possible to prevent the paper feed failure due to the variation of the pressing force, and the pair of pressure feed rollers move in parallel during the retracting operation. For,
The transport path can be opened reliably.

Further, it is preferable that the pressure feed roller and the roller retraction mechanism are provided in a scanner feed unit separated from the scanner, and that the entire scanner feed unit is retractable from the scanner. . In this case, by retracting the entire scanner feeding unit, it is possible to widely open the gap between the scanner and the pressure feeding roller, which makes it easy to remove the jammed paper at the scanner site.
The reading surface of the scanner can be easily cleaned.

Further, it is preferable that the scanner feeding unit is further provided with a platen arranged at a position facing the print head. In this case, as the scanner feed unit is retracted, the gap between the print head and the platen is widely opened, so that the jammed paper at the print head portion can be easily removed.

Further, it is preferable that the scanner feeding unit is further provided with one of a pair of feeding rollers arranged on the upstream side of the scanner. In this case, as the scanner feed unit is retracted, the gap between the feed roller pairs is widely opened, so that it is easy to remove the jammed paper at the feed roller pair portion. Further, in order to achieve the above object, a method for controlling a composite processing apparatus according to the present invention is claim

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a composite processing apparatus according to an embodiment of the present invention. As shown in this figure, the composite processing apparatus 10 is covered with a cover 11 made of resin, and an insertion opening 12 for inserting a check P by hand is formed on the front surface of the composite processing apparatus 10, while the upper surface is provided. Has a discharge port 13 for discharging the check P. Further, the composite processing apparatus 10 of the present embodiment is provided with a roll paper storage unit (not shown) for storing roll paper at its rear part, and the roll paper stored in the roll paper storage unit passes through the printing unit. It is pulled out from the roll paper discharge port 14 on the upper surface of the apparatus.

FIG. 2 is a side sectional view showing the internal structure of the composite processing apparatus. As shown in this figure, a conveyance path 15 for a check P extending from the insertion port 12 to the ejection port 13 is formed inside the multi-processing apparatus 10. The transport path 15 has the insertion port 12 side facing the horizontal direction and the discharge port 13 side facing the vertical direction, and is bent in an L shape in a side view.
On the transport path 15, the sheet trailing edge detector 16, the MICR head (magnetic head) 17, and the first sheet are arranged in order from the insertion port 12 side.
Feed roller pair 18, paper tip detector 19, paper positioning member 20, back print head (second print head) 21, second feed roller pair 22, front print head (first print head) 23, paper discharge detection A container 24 and a scanner 25 are arranged, and a scanner feed roller (pressure feed roller) 26 is provided at a position facing the scanner 25.

Paper trailing edge detector 16, paper leading edge detector 19
The paper discharge detector 24 is composed of, for example, a transmissive or reflective photosensor, and detects the presence or absence of the check P at each position of the transport path 15 in a non-contact manner. The sheet positioning member 20 is for temporarily stopping the check P inserted from the insertion slot 12 at a predetermined position, and for example, is driven by an actuator such as a solenoid or the like, to convey the conveyance path 15.
It is configured to transform into a posture of projecting inward and a posture of retracting from the transport path 15. 1st feed roller pair 1
8 and the second feed roller pair 22 are respectively in the transport path 1
The check P is constituted by a pair of roller members opposed to each other with the roller 5 interposed therebetween, and the check P is conveyed in both forward and reverse directions by driving one of the rollers. Further, one of the roller members is configured to be movable back and forth with respect to the other roller member, and opens and closes the transport path 15 by a moving back and forth operation in response to actuator driving such as a solenoid.

The MICR head 17 is for reading the magnetic ink characters recorded on the surface of the check P.
Check P based on the data read by the ICR head 17
Is determined to be valid or invalid. The magnetic ink characters are recorded in the MICR recording area 27 on the surface of the check P, as shown in FIG.
Account number etc. are included. The MICR head 17
Check P at the opposite position of
Although a pressing member 17a for pressing the head 17 is provided, the pressing member 17a is normally retracted from the MICR head 17 and the transport path 15 is opened.

The front print head 23 is provided on the surface of the check P.
It is used to print out a written matter such as a payee, a date, and an amount of money. The written matter is printed in a written area 28 shown in FIG. The front print head 23 is a serial print head supported by a carriage, and realizes dot matrix printing for each one or plural rows while moving in the width direction of the check P. In the present embodiment, a dot impact type print head that transfers the ink on the ink ribbon to the check P is used as the front print head 23, but another type of print head may be used.

The back print head 21 is for printing on the back side of the check P the endorsement items necessary for the shop side, such as the shopper's authentication number, date, and amount spent, and this endorsement item is shown in FIG. Is printed in the endorsement area 29 shown in FIG. The back print head 21 is of the shuttle type and has a check P
A plurality of heads are provided at predetermined intervals in the width direction, and dot matrix printing of one or a plurality of rows is realized by moving the heads within the interval width. In the present embodiment, a dot impact type print head that transfers the ink on the ink ribbon to the check P is used as the back print head 21, but a print head of another type may be used.

The scanner 25 is for scanning the surface of the printed check P. The scanned image data is compressed and then stored in the host computer for electronic payment. In this embodiment,
As the scanner 25, a contact image sensor (CIS:
Contact image sensor) is used, and the scanning operation is performed with the check P being in close contact with the reading surface 25a.

The scanner feed roller 26 is for carrying the check P during the scanning operation. While the check P is being pressed against the reading surface 25a of the scanner 25, the check P is carried to the discharge port 13 side. At this time, the scanner feed roller 26 presses the check P at a position slightly deviated from the scanner focus position A without pressing the check P at the focus position A of the scanner 25, as shown in FIG. That is, the scanner focus position A is offset from the scanner contact position B of the scanner feed roller 26 to the upstream side or the downstream side of the transport. For example, in the present embodiment, from the scanner contact position B of the scanner feed roller 26 The scanner focus position A is set at a position offset by 0.8 mm to the downstream side of the conveyance (the discharge port 13 side). This prevents the pressing force of the scanner feed roller 26 from directly acting on the scanner focus position A. Therefore, when the check P is scanned immediately after printing, it is possible to reduce the amount of ink attached to the scanner focus position A, and it is possible to prevent deterioration of the quality of the scan image due to ink attachment as much as possible. Further, in the present embodiment, as described above, the scanner focus position A is offset downstream of the scanner contact position B of the scanner feed roller 26, so that the front end side scannable area of the check P is widened. Will be possible. Note that the scanner focus position A is set to the scanner contact position B of the scanner feed roller 26.
If the check P is largely offset with respect to the check surface P, the check P may float from the reading surface 25a at the scanner focus position A. However, since the offset amount is about 0.8 mm as described above, The float is suppressed to 0.2 mm or less, and there is no fear of degrading the quality of the scanned image.

In the above scanning operation, the scan feed roller 26 conveys the check P upward and ejects the check P from the ejection port 13 as it is. At this time, the trailing end of the discharged check P is held on the downstream transport path 15 of the scan feed roller 26. That is, the end portion of the transport path 15 (between the scan feed roller 26 and the discharge port 13)
Is oriented in a substantially vertical direction, and a length of about L / 6 (L: length of check P) is secured.
Can be held, and the check P after discharge does not drop from the composite processing apparatus 10.

FIG. 5 is a side view showing the roller retracting mechanism, and FIG. 6 is a plan view showing the roller retracting mechanism. As shown in these figures, a pair of scanner feed rollers 26 are provided on the roller support shaft 30 at a predetermined interval. Both ends of the roller support shaft 30 are guided so as to be movable back and forth along the guide grooves 31, and an intermediate portion thereof is supported by a roller retracting mechanism 32 described later. The roller retraction mechanism 32 is
The roller support shaft 30 is pulled rearward in response to the driving of the scanner feed roller solenoid 33, and accordingly, the scanner feed roller 26 is retracted from the scanner 25 and the conveyance path 15 is opened. That is, during the non-scan operation, the scanner feed roller 26 is in the retracted position, and the check P is prevented from being caught in the scanner feed roller 26. Further, during the scanning operation, the first feed roller pair 18 and the second feed roller pair 22
After the check P is conveyed to the scan start position by the check, the scanner feed roller 26 is released and the check P is released.
Is pressed against the scanner 25, and the scanner feed roller 26 is driven in this state to carry the check P.

The roller retraction mechanism 32 is provided on the roller support shaft 30.
A pressing lever (rotating member) 34 that rotatably supports and moves back and forth with respect to the scanner 25, and a pressing spring 35 that biases the pressing lever 34 toward the scanner 25.
And a scanner feed roller solenoid 33 for retracting the pressing lever 34 against the urging force of the pressing spring 35. The presser lever 34 is a rotating member that can be rotated back and forth about a rotating support shaft 34a as a fulcrum, and by supporting the roller support shaft 30 of the scanner feed roller 26 with the rotating member, the roller retracts. The mechanism 32 can be configured compactly and the forward / backward movement can be smoothly performed. The presser lever 34 rotatably supports the roller support shaft 30 between the pair of left and right scanner feed rollers 26. Therefore, the pair of scanner feed rollers 26
Can be biased substantially evenly by a single pressing spring 35, and moreover, during the retracting operation, the pair of scanner feed rollers 26 are kept in a substantially parallel state, and the transport path 15 is reliably opened.

Further, the roller retraction mechanism 32 is provided with a drive system for driving the scanner feed roller 26. The drive system of the scanner feed roller 26 is provided with a first gear 36 integrally provided on the roller support shaft 30 between the pair of scanner feed rollers 26 and a presser lever 34.

When the determination result is received from the host computer, it is determined whether or not the determination result is valid (S808). If the check P is invalid here, the invalid check ejection process (S809) is executed to execute the first process. Exit control mode. On the other hand, if the check P is valid, the back print position is set (S811, FIGS. 9 (4), (5), and FIG. 12) while driving the carry motor 41 in the discharge direction (S810). The back print position setting and each position setting described later are performed by the predetermined detectors 16, 19, 2,
Based on the detection position of 4 as a reference, it is performed based on the number of transfer steps from the reference position (including stop of transfer). When the back printing position setting is completed, the back printing process (S813, FIGS. 9 (6) and (7)) by the back printing head 21 is executed while driving the conveyance motor 41 in the insertion port direction (S812).

In consideration of workability in removing a paper jam generated between the scanner 25 and the scanner feed roller 26, the scanner feed roller 26 and the roller retracting mechanism 32 are configured to be largely retracted from the scanner 25. The configuration will be described below with reference to FIG.

FIG. 17 is a schematic side view of the inside of the composite processing apparatus showing the retracting structure of the scanner feeding unit. As shown in this figure, a scanner feeding unit 46 separated from the scanner 25 is formed at a position facing the scanner 25. The scanner feed unit 46 is configured to include the scanner feed roller 26, the roller retracting mechanism 32, the scanner feed motor 38, and the like described above, and is rotatable inside the multi-processing apparatus via the unit rotation support shaft 47. It is supported. When the entire scanner feed unit 46 is retracted and rotated backward (up to 90 ° in this embodiment) about the unit rotation support shaft 47 as a fulcrum, the scanner feed roller 26 and the roller retracting mechanism 32 are largely retracted from the scanner 25, and the scanner is moved. The space between 25 and the scanner feed roller 26 is widely opened. As a result, it becomes easy to remove jammed paper at the scanner 25 portion and to clean the reading surface 25a. Further, on the front surface of the scanner feed unit 46, a platen 23 a arranged at a position facing the front print head 23 and one roller member 22 a forming the second feed roller pair 22 are provided.

Can be avoided, and as a result, it is possible to prevent jamming and deviation of the feed pitch.

Further, the end portion of the check P discharged by the scanner feed roller 26 is the scanner feed roller 26.
Since it is held by the downstream side vertical transport path 15, the number of parts can be reduced and the structure can be simplified as compared with the case where a dedicated holding member is provided.

Since the focus position A of the scanner 25 is offset upstream or downstream of the scanner contact position B of the scanner feed roller 26, the scanner feed roller 2 is positioned at the focus position A of the scanner 25.
It is avoided that the pressing force of 6 directly acts. Therefore,
