Specifically, in this embodiment, when the check 4 is set correctly without being set upside down and upside down, the check 4 is discharged into the main pocket 19a, while the check 4 is set correctly. If not, the check 4 is discharged into the sub-pocket 19b. In step SA5, the processing control unit 70a switches the switching plate 54 to the main pocket 19a side when the check 4 is set correctly, and switches the switching plate 54 to the sub pocket 19b side when the check 4 is not set correctly. Switch.

Next, the processing control unit 70a monitors the position of the check 4 by monitoring the detection value of the intermediate detector 46, and further drives the various motors by driving the transport motor 42 to further transport the check 4, and the inkjet head 10, a predetermined image is recorded on the back surface 4b of the check 4 (step SA6). If the check 4 is not set correctly, image recording may not be performed in step SA7.
Next, the processing control unit 70a optically reads the front surface 4a of the check 4 by the front surface CIS unit 47, optically reads the back surface 4b by the back surface CIS unit 48, and outputs the read result to the host computer 5 (step SA7). ). If the check 4 is not set correctly, the check 4 may not be read in step SA7.
Next, the processing control unit 70a drives the various motors by driving the transport motor 42 while monitoring whether the check 4 has been normally discharged by monitoring the detection value of the discharge detector 52. The check 4 is discharged into the pocket 19 (step SA8). At that time, the check 4 is guided to the switching plate 54 and discharged into the appropriate pocket 19 corresponding to the reading result of the MICR head 35 out of the main pocket 19a and the sub pocket 19b.

Next, the single processing mode will be described.
In the continuous processing mode described above, a series of processing is continuously executed for the check 4 stored in the stocker 15. On the other hand, in the single processing mode, the predetermined processing described below is executed independently for one check 4.
This single processing mode is an operation mode for the following purposes.
That is, in the above-described continuous processing mode, the back side 4b of the check 4 is optically read by the back side CIS unit 48 after an image related to the end point is recorded. On the other hand, there is a real need to record an image on the back surface 4b after optically reading the back surface 4b before the image related to the endorsement is recorded. Based on this, the single processing mode automatically optically reads the back surface 4b before the image related to the endorsement is recorded, without going through artificial means such as reinserting the check 4 by the user. The purpose is to record an image on the back surface 4b later. Furthermore, in the single processing mode, as will be described below, the processing efficiency is improved by executing appropriate operations based on the structure of the composite processing apparatus 1, thereby improving customer satisfaction and product value. Is realized.

Note that the fact that the single processing mode is provided as the operation mode also has the following background.
That is, the composite processing apparatus 1 according to the present embodiment has been developed as a successor of a certain medium processing apparatus. In this conventional medium processing apparatus, the back surface CIS unit is provided on the upstream side and the ink jet head is provided on the downstream side in the conveyance path. Therefore, when the conventional media processing apparatus optically reads the back surface 4b of the check 4 and then records an image on the back surface 4b, the host computer applies the optical data to the media processing apparatus accordingly. A control command for executing reading and a control command for recording an image were sequentially input.
Here, it is considered that the medium processing apparatus is replaced with the composite processing apparatus 1 as a successor. In this case, if it is possible to replace the media processing apparatus with the composite processing apparatus 1 as a successor without modifying the host computer 5 (modification of a device driver, installation of a new device driver, etc.) The work to be performed by the user and the knowledge to be acquired can be reduced, customer satisfaction can be improved, replacement can be promoted, and sales opportunities can be expanded. In order for the medium processing apparatus to perform a desired operation similar to the conventional one without modifying the host computer 5, at least a control command for executing optical reading of the back surface 4b of the check 4 from the host computer 5, When control commands for recording an image on the back surface 4b are sequentially input, first, the back surface 4b of the check 4 is optically read in accordance with these control commands, and then the image is recorded on the back surface 4b. It needs to be possible.
Based on the above, in the composite processing apparatus 1 according to the present embodiment, a control command for executing optical reading of the back surface 4b of the check 4 and a control command for recording an image on the back surface 4b are sequentially input from the host computer 5. In this case, in accordance with these control commands, first, the single processing mode is provided so that the back side 4b of the check 4 can be optically read and then the image can be recorded on the back side 4b.

FIG. 5 is a sequence diagram showing the operation of the composite processing system 8 in the single processing mode, where (A) shows the operation of the host computer 5 and (B) shows the operation of the composite processing apparatus 1. (X) represents the user's action.
In the following description, it is assumed that no check 4 is stored in the stocker 15 at the start of the operation.
In the single processing mode, first, the host computer 5 causes the composite processing apparatus 1 to perform preparations necessary for the check 4 to be stored in the stocker 15 (for example, movement of the hopper 25 to the standby position). Then, a control command for instructing to wait until the check 4 is stored is output (step SB1). In response to this control command, the processing control unit 70a of the control unit 70 of the composite processing apparatus 1 monitors whether or not the check 4 is stored in the stocker 15 based on the detection value of the ASF paper detector 31. Wait (step SB2).
Next, when the check 4 is stored in the stocker 15 by the user (step SX1), the processing control unit 70a detects that based on the detection value of the ASF paper detector 31, and A command including a status indicating that the check 4 has been stored is output (step SB3). In response to the command including the status, the host computer 5 outputs a control command to end preparation and instructing in step SB1 (step SB4). Based on this control command, the processing control unit 70a finishes preparation and standby for storing the check 4 (step SB5).

Next, the host computer 5 outputs a control command for causing the composite processing apparatus 1 to read the back surface 4b of the check 4 (step SB6). The front surface 4a of the check 4 may also be read together. However, for convenience of explanation, in step SB6, the host computer 5 performs reading of the back surface 4b to read the back surface 4b. A control command shall be output.
Based on this control command, the process control unit 70a drives the hopper drive motor 26, the ASF motor 27, and the transport motor 42 while monitoring various sensors, and moves the check 4 stored in the stocker 15 to the transport path W. The check 4 is transported to the reading position of the back CIS unit 48, the back surface 4b of the check 4 is optically read by the back CIS unit 48, and the read result is read by the host computer. 5 (step SB7).
In step SB7, after the reading of the back surface CIS unit 48 is completed, the processing control unit 70a stops the conveyance of the check 4 while a part of the check 4 is sandwiched between the second CIS rollers 51. Due to the positional relationship between the back CIS unit 48 and the second CIS roller 51, the second CIS roller 51 is stopped by stopping the driving of the check motor 4 immediately after the reading by the back CIS unit 48 is finished. It is possible to stop the conveyance of the check 4 while maintaining a state where a part of the check 4 is held between the checks 4.

  Next, the host computer 5 outputs a control command that notifies the check 4 that the mechanism for processing is switched from the back surface CIS unit 48 to the inkjet head 10 (step SB8). Based on this control command, the processing control unit 70a detects that recording on the back surface 4b of the check 4 is performed, and performs processing necessary for recording an image with the inkjet head 10 (for example, canceling capping). Or flushing) (step SB9).

Next, the host computer 5 outputs a control command for recording an image on the back surface 4b of the check 4 (step SB10).
In response to this control command, first, the process control unit 70a back-feeds the check 4 to a position where an image can be recorded by the inkjet head 10 (step SB11).
Hereinafter, the process of step SB11 will be described.

FIG. 6 is a diagram for explaining the process of step SB11.
In FIG. 6, while partially showing the conveyance path W, the inkjet head 10 provided in the conveyance path W is typically shown.
In the transport path W of FIG. 6, the right direction is the direction corresponding to the direction in which the stocker 15 is provided, and the left direction is the direction corresponding to the direction in which the pocket 19 is provided. Various processes are performed while the check 4 is conveyed in the conveyance direction YJ1 which is a direction from the middle right side to the left side.
In FIG. 6, T <b> 1 indicates the position of the nozzle row N formed on the ink jet head 10 (recording position by the ink jet head 10), and T <b> 2 schematically indicates the position where the presence or absence of the check 4 is detected by the intermediate detector 46. It shows.
As shown in FIG. 6, in the inkjet head 10 according to the present embodiment, the nozzle row N extends in the nozzle row direction YJ2, which is a direction intersecting the transport direction YJ1, and the check is made by the nozzle row N. An image can be recorded in a wide range of four nozzle row directions YJ2 (substantially the entire area of the check 4 in the nozzle row direction YJ2). In FIG. 6, one nozzle row N is provided in the inkjet head 10, but a plurality of nozzle rows may be provided in the inkjet head 10.
Further, the inkjet head 10 conveys the check 4 at a constant speed toward the conveyance direction YJ1 due to the form of the drive circuit, the state of other devices in the conveyance path W, and other software hardware factors. In this situation, it is possible to record an image by discharging ink, and it is not possible to record an image while conveying the check 4 in the direction opposite to the conveyance direction YJ1.
In the following description, the end of the check 4 in the transport direction YJ1 is referred to as “check leading edge 4d”, and the opposite end is referred to as “check trailing edge 4e”, and an image is actually recorded on the back surface 4b of the check 4. An end on the transport direction YJ1 side of the recording area R, which is an area, is referred to as “recording area front end Ra”, and an opposite end is referred to as “recording area rear end Rb”.
Further, in the following description, conveying the check 4 in the direction opposite to the conveyance direction YJ1 is referred to as back feed.

The position of the check 4 in FIG. 6A is the position when the reading of the back surface 4b by the back surface CIS unit 48 is completed and the conveyance is stopped (= when the processing of step SB7 is completed).
In step SB11, first, the processing control unit 70a drives the conveyance motor 42 to start the back feed of the check 4 at the position of FIG. 6A, and based on the change in the detection value of the intermediate detector 46. Thus, it is monitored whether or not the check trailing end 4e of the check 4 has reached the position T2 of the detection position of the intermediate detector 46.
When the back feed of the check 4 advances and the check rear end 4e of the check 4 reaches the position T2 of the detection position of the intermediate detector 46 (the state shown in FIG. 6B), the processing control unit 70a This is detected based on the detected value.
After the detection, the processing control unit 70a further back-feeds the check 4 by a predetermined distance so that the recording area tip Ra of the recording area R of the check 4 is positioned upstream of the position T1 of the nozzle row N. End backfeed. That is, the processing control unit 70a manages the position of the check 4 by detecting the check trailing edge 4e of the check 4 by the intermediate detector 46, and backfeeds the check 4 until the check 4 is positioned at a predetermined position. To do.

Hereinafter, the operation after detection of the check trailing edge 4e of the check 4 by the intermediate detector 46 will be described in detail with reference to FIGS. 6B and 6C.
The position of the check 4 in FIG. 6C is the position of the check 4 at the end of the back feed. FIG. 6C shows a state where the recording area leading edge Ra of the recording area R of the check 4 is positioned upstream of the position T1 of the nozzle array N by a margin M at the time when the back feed is completed. . This margin M is such that when the conveyance of the check 4 in the conveyance direction YJ1 is started after the end of the back feed, the conveyance speed of the check 4 is at least until the recording area leading edge Ra reaches the position T1 of the nozzle row N. , A margin necessary for accelerating to a constant speed necessary for recording.
When the processing controller 70a detects the check trailing edge 4e of the check 4 by the intermediate detector 46, the difference between the separation amount L1 between the check trailing edge 4e and the recording area leading edge Ra and the separation amount L2 between the position T1 and the position T2. The check 4 is back-fed by the transport amount including the margin M to the distance L3 (see FIG. 6B). The control command input from the host computer 5 includes information indicating the position of the recording area leading edge Ra on the back surface 4b of the check 4 and information indicating the size of the check 4. The processing control unit 70a Based on the information, the separation amount L1 is calculated. The separation amount L2 is a fixed value and is defined in advance on the control program. In this manner, after the check trailing edge 4e of the check 4 is detected by the intermediate detector 46, back feed is performed by the conveyance amount obtained by adding the margin M to the distance L3. The recording area leading edge Ra of the recording area R of the check 4 is positioned upstream of the N position T1 by the margin M.

As described above, in this embodiment, when the check 4 is back-fed, not all of the checks 4 are positioned upstream from the position T1 of the nozzle row N, but at least the recording region tip Ra is the nozzle row N. The check 4 is back-fed so that it is positioned upstream of the position T1. Here, the back feed is performed in order to perform recording by the inkjet head 10. If the recording region leading edge Ra is positioned upstream of the position T1 of the nozzle row N, an image can be recorded by ejecting ink to the recording region R by the nozzle row N. In consideration of this, in the present embodiment, the backfeed is performed by the minimum conveyance amount necessary for recording, so that the processing efficiency is improved and the time required for the backfeed can be shortened.
In the present embodiment, the first CIS roller 50, the second CIS roller 51, the first transport roller 40, and the second transport roller 41 used when the check 4 is back-fed are rotated by the transport motor 42, while the ASF is used. Since the roller 29 is rotated by an ASF motor 27 different from the transport motor 42, the check trailing edge 4 e of the check 4 cannot back-feed past the ASF roller 29 upstream during backfeed. In the present embodiment, when the back feed is performed, the minimum amount of conveyance necessary for recording an image on the back surface 4b of the check 4 is back fed. Therefore, when the back feed is performed, the check of the check 4 is performed. The probability that the trailing edge 4e exceeds the ASF roller 29 can be reduced as much as possible. Therefore, it is possible to automatically record an image without using human means as much as possible. Note that the processing control unit 70a determines that the back end 4e of the check 4 is upstream of the ASF roller 29 when the back feed is performed based on the separation amount L1 between the check rear end 4e and the recording area front end Ra before the back feed. If it exceeds, the back feed is stopped, and a message to that effect is output to the host computer 5.

  Furthermore, as described above, in the inkjet head 10 according to the present embodiment, the nozzle row N extends in the nozzle row direction YJ2, and the nozzle row N allows the check 4 to have a wide range in the nozzle row direction YJ2 (check). The image can be recorded in almost all of the four nozzle row directions YJ2. Due to such a configuration, the following effects are produced.

FIG. 7 is a diagram schematically showing the back surface 4b of the check 4 in order to explain the above effect, and FIG. 7A is a back surface when an image related to the endorsement is recorded by the composite processing apparatus 1 according to the present embodiment. An example of 4b is shown, and (B) shows an example of the back surface 4b when an image related to the endorsement is recorded by a conventional composite processing apparatus.
In the following description, the date of processing the check 4 (“2011/01/01” in the example of FIG. 7), the name of the maker (“XXX” in the example of FIG. 7), and It is assumed that three pieces of information of the financial institution that processed the check 4 (“AAABank” in the example of FIG. 7) are recorded on the check 4 as an endorsement.
As shown in FIG. 7A, in the combined processing apparatus 1 according to this embodiment, an image can be recorded in a wide range in the nozzle row direction YJ2 of the check 4, so that each information to be recorded on the check 4 is It can be recorded as a multi-line character string.
On the other hand, as shown in FIG. 7B, the conventional combined processing apparatus has a narrow range in which the nozzle row extends in the nozzle row direction YJ2, and each line of information to be recorded on the check 4 is a character string. Could only be recorded.
As is apparent from a comparison between FIG. 7A and FIG. 7B, in this embodiment, since information can be recorded as a character string of a plurality of lines, the image extends in the transport direction YJ1. The range becomes narrower than that of the conventional case, and therefore, the length of the separation amount L1 between the recording region leading edge Ra and the check rear end 4e can be made smaller than that of the conventional case. For this reason, when the check 4 is back-fed, the conveyance amount to be back-fed can be reduced, further processing efficiency can be achieved, and the back end 4e of the check exceeds the ASF roller 29 to the upstream side, so back-feeding is not possible. The probability of occurrence of the situation can be further reduced.

Now, after back-feeding the check 4 in step SB11, the processing control unit 70a starts transporting the check 4 in the transport direction YJ1, and transports the check 4 at a constant speed while the check 4 is being transported by the inkjet head 10. An image is recorded on the back surface 4b (step SB12). As described above, since the back feed is performed reflecting the margin M in consideration of acceleration, the check is made until the recording area leading edge Ra reaches the position T1 of the nozzle row N after the start of the conveyance in the conveyance direction YJ1. It is possible to accelerate the transport speed of the check 4 so that the speed at which 4 is transported becomes a predetermined speed.
After recording the image on the check 4, the host computer 5 outputs a control command instructing to discharge the check 4 into the pocket 19 (step SB 13). Based on this control command, the processing control unit 70a monitors the detection value of the discharge detector 52 to monitor whether or not the check 4 is normally discharged, and drives the carry motor 42 to drive various types of operations. The motor is driven and the check 4 is discharged into the pocket 19 (step SB14).

As described above, the processing control unit 70a according to the present embodiment, when reading the check 4 by the back surface CIS unit 48, performs recording on the check 4 by the inkjet head 10, based on the detection value of the intermediate detector 46. 4, the position of the check 4 is managed, and at least upstream of the position T 1 of the nozzle row N where the recording area leading edge Ra of the recording area R in the check 4 is the recording position by the inkjet head 10. After back-feeding until it is positioned at position, the check 4 is conveyed in the conveyance direction YJ1 to record an image.
According to this, at the time of back feed, since the recording area leading edge Ra of the recording area R in the check 4 is back fed until it is located upstream of the position T1 of the nozzle row N, the conveyance amount at the time of back feeding is The minimum transport amount necessary for recording on the check 4 by the inkjet head 10 is obtained, and the processing efficiency is improved. Further, since the position of the check rear end 4e, which is the end on the side of the check 4 at the time of back feed, is detected and the position of the check 4 is managed, the check rear end 4e is detected after the check rear end 4e is detected. And back the check 4 until the recording area leading edge Ra of the check 4 is located upstream of the position T1 by a simple operation of back feeding the medium by a predetermined amount based on the separation amount L1 between the recording area leading edge Ra and the recording area leading edge Ra. It is possible to feed, and the processing efficiency is improved.
Furthermore, it is conceivable that the entire check 4 is positioned upstream of the position T1 when backfeeding. However, due to the structure of the transport path W, in this embodiment, the transport amount during backfeed is limited. is there. However, according to the above configuration, the amount of conveyance at the time of backfeed becomes the minimum necessary, so even if the amount of conveyance at the time of backfeed of the check 4 is limited as in this embodiment, with a high probability. Therefore, it is possible to perform back feed necessary for recording after reading.

In addition, the inkjet head 10 according to the present embodiment is formed with a nozzle array N extending in the nozzle array direction YJ2, and is transported from the fixed inkjet head 10 in the transport direction YJ1 at a constant speed. Ink can be ejected onto the check 4 and an image can be recorded in a wide range of the check 4 in the nozzle row direction YJ2.
According to this, since an image can be recorded in a wide range in the nozzle row direction YJ2 of the check 4, the same information is compared with that in which an image can be recorded in a narrow range in the nozzle row direction YJ2 of the check 4. When recorded, the information can be recorded in a narrower range in the transport direction YJ1. Therefore, the distance L1 between the recording region leading edge Ra and the check trailing edge 4e in the check 4 can be shortened, and when backfeeding, the transport amount during backfeeding is shortened, and the work related to backfeeding is performed. More efficient.

In addition, when the check 4 is back-fed, the processing control unit 70a according to the present embodiment is necessary for acceleration from the start of conveyance in the conveyance direction YJ1 after the back feed until the conveyance speed reaches a constant speed. Based on the margin M, the check 4 is back-fed.
According to this, the back feed can be appropriately executed in consideration of the characteristic of the apparatus that records the check 4 while being conveyed at a constant speed.

The above-described embodiment is merely an aspect of the present invention, and can be arbitrarily modified and applied within the scope of the present invention.
For example, in the above-described embodiment, the composite processing apparatus 1 has a structure in which the MICR head 35, the inkjet head 10, and the CIS unit are sequentially arranged on the transport path W.
