Description

[Technical field]

[0001] The present invention relates to a media processing device. [Background technology]

[0002] As an example of ejection control in a media processing device that processes media, there is a method of transporting the medium to an ejection position based on the rear end (end on the ejection side) of the medium (see, for example, Patent Document 1). The media processing device described in Patent Document 1 transports the medium along a transport path and performs a predetermined process, then transports the medium in the reverse direction and discharges it into the insertion and discharge opening, and opens the nip between the transport rollers closest to the insertion and discharge opening. When discharging the medium, the medium is transported so that the rear end of the medium stops at a predetermined stopping position that is a predetermined distance away from a reference position of the transport path in the discharge direction.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-232399 Summary of the Invention [Problem to be solved by the invention]

[0004] Patent document 1 does not disclose discharge control for media whose length has not been detected, and therefore it is not possible to properly discharge media whose length has not been detected (including media whose end position on the discharge side has not been determined). For example, a bankbook slip printer is known as one type of media processing device, and it is common for this bankbook slip printer to process media of different media lengths. Therefore, when a medium is inserted into the bankbook slip printer, the printer first performs control to detect the media length (media length detection control). However, if processing is canceled before the media length detection control is performed, the printer ejects the media with the media length undetected, which creates the problem that the appropriate ejection position cannot be calculated.

[0005] The present invention has been made in consideration of the above-mentioned problems, and provides a media processing device that can properly eject media whose length has not been detected. [Means for solving the problem]

[0006] In order to solve the above problem, a media processing device according to one embodiment of the present invention comprises an insertion / ejection port through which media of different lengths are inserted and ejected, an insertion / ejection transport path along which the inserted and ejected media are transported, a sensor installed on the insertion / ejection transport path for detecting the presence of the media, and a control unit for controlling the transport of the media, wherein when the control unit ejects the media that has been transported to a first position on the insertion / ejection transport path after insertion, the control unit transports the media from the first position back in the ejection direction to a second position, and transports the media to a discharge position based on the detection result of the sensor when the media is at the second position. Effect of the Invention

[0007] According to the present invention, a medium whose length has not been detected can be properly ejected. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Each drawing is merely a schematic illustration to the extent that the present invention can be fully understood. Therefore, the present invention is not limited to only the illustrated examples. In addition, in the drawings to which reference is made, the dimensions of the members constituting the present invention may be exaggerated or otherwise expressed in order to clarify the explanation. In addition, in each drawing, the same reference numerals are given to common or similar components, and their repeated explanations are omitted.

[0010] [First embodiment] <Configuration of the media processing device according to the first embodiment> The configuration of a media processing device 1 according to a first embodiment will be described with reference to Figure 1. Figure 1 is a schematic diagram of the media processing device 1. In the explanation of the media processing device 1, "up and down" and "front and back" refer to the arrows in Figure 1. These directions are defined for the convenience of explanation and do not limit the invention. Note that the front side in Figure 1 is an example of the "ejection direction" and the rear side is an example of the "insertion direction".

[0011] The media processing device 1 is a device that processes media. Media include, for example, bankbooks, slips, cards, and tickets. In this embodiment, the media processing device 1 will be described as a bankbook slip printer. A bankbook slip printer is a device that prints on different types of media, namely bankbooks and slips. A bankbook slip printer is operated, for example, by a person (operator) in charge of counter operations at a financial institution.

[0012] The media processing device 1 shown in Figure 1 (which in this embodiment is assumed to be a passbook slip printer) mainly comprises an inserter unit 2, a printing unit 3, and an auto-turn page (ATP) unit 4. These units are installed side by side in the front-to-back direction inside a housing 1a. The media processing device 1 also comprises a control unit 20 that controls the operation of the inserter unit 2, printing unit 3, and auto-turn page unit 4. The control performed by the control unit 20 includes control over media transport.

[0013] The media processing device 1 includes a transport path 9 along which the media is transported, and multiple sensors S are installed on the transport path 9 to detect the presence of media. The sensors S are, for example, photoelectric sensors, and are capable of detecting the presence of media from changes in the amount of light. The sensors S detect the "presence / absence" of media, for example, from light / dark states. In this embodiment, the sensors S are ON when they detect the presence of media, and OFF when they do not detect the presence of media. The sensors S send a signal corresponding to the ON / OFF state to the control unit 20. The conveying path 9 is made up of upper and lower guide portions 12 that guide the medium, conveying feed rollers 10 that convey the medium, conveying pressure rollers 11 that press the medium against the conveying feed rollers 10, and the like.

[0014] The conveying feed rollers 10 are connected to a conveying pulse motor (not shown) and rotate by the driving force of the conveying pulse motor. The conveying pressure rollers 11 are disposed opposite the conveying feed rollers 10. A transport path 9 is provided across the inserter unit 2, the printing unit 3, and the auto-turn page unit 4, and the medium can be moved between the units via the transport path 9.

[0015] The inserter unit 2 shown in Fig. 1 is mounted on the front side of the media processing device 1. The inserter unit 2 has the function of receiving media such as bankbooks and slips set by the operator, taking in the set media, and ejecting media after printing has been completed. The inserter unit 2 has an upper inserter section 2a and a lower inserter section 2b. The upper inserter section 2a and the lower inserter section 2b are arranged next to each other in the vertical direction.

[0016] The upper inserter section 2a is configured to accept slips and has a slip stage (not shown) for setting the slip, and a slip insertion and ejection port 5 for inserting slips into the device and ejecting them out of the device. The lower inserter section 2b is configured to receive passbooks, and has a passbook stage (not shown) for setting the passbook, and a passbook insertion and ejection port 6 for inserting the passbook into the device and ejecting it from the device.

[0017] The transport path 9 that continues from the document insertion and discharge port 5 and transports media inserted from the document insertion and discharge port 5 and discharged to the document insertion and discharge port 5 will be referred to as the "insertion and discharge transport path 9a." The insertion and discharge transport path 9a is, for example, the section between the document insertion and discharge port 5 and the printing unit 3. The conveying path 9, which is continuous with the passbook insertion and ejection opening 6 and conveys the medium to be inserted into and ejected from the passbook insertion and ejection opening 6, will be referred to as the "insertion and ejection conveying path 9b." The insertion and ejection conveying path 9b is, for example, the portion between the passbook insertion and ejection opening 6 and the printing unit 3.

[0018] As shown in Fig. 1, the insertion and discharge conveying path 9a and the insertion and discharge conveying path 9b join together in front of (upstream of) the reading section 7 of the printing unit 3. As a result, a slip inserted through the slip insertion and discharge port 5 and a passbook inserted through the passbook insertion and discharge port 6 are inserted at different locations but pass through the same conveying path 9 behind the device (downstream) from the point where the conveying paths join. Note that the insertion and discharge conveying path 9b is shorter than the insertion and discharge conveying path 9a. The insertion and discharge conveying path 9a and the insertion and discharge conveying path 9b are examples of an "insertion conveying path" and a "discharge conveying path".

[0019] As shown in Fig. 1, a first sensor S1 and a second sensor S2 are installed on the insertion / ejection transport path 9b. The first sensor S1 is used to detect the rear end of the medium when detecting the length of the medium in the transport direction (front-rear direction) (referred to as the "medium length"). The second sensor S2 is used to detect the front end of the medium when detecting the medium length. The second sensor S2 is installed further in the insertion direction (rear) than the first sensor S1. A fourth sensor S4 is also installed on the insertion / ejection transport path 9a. When detecting the medium length, the fourth sensor S4 operates as a leading end detection sensor that determines the leading end of the medium and a trailing end detection sensor that determines the trailing end of the medium. The medium length is detected when a medium is inserted into the media processing device 1. Details of the medium length detection control will be described later.

[0020] The printing unit 3 shown in Fig. 1 is mounted behind the inserter unit 2. The printing unit 3 has a function of printing on media (slips and passbooks) and a function of detecting printed lines for printing. Specifically, the printing unit 3 has a reading unit 7 and a print head 8. The reading unit 7 reads page marks and printed lines of a passbook, which is a medium, and print lines of a slip. The print head 8 prints on the passbook and slip, which are media.

[0021] The auto-turn page unit 4 shown in Fig. 1 is mounted behind the printing unit 3. The auto-turn page unit 4 has a function for turning the pages of a passbook. When it is determined that a page needs to be turned, the passbook is transported from the printing unit 3 to the auto-turn page unit 4, which then turns the page and sends the passbook back to the printing unit 3.

[0022] (Regarding media capture control (including "media length detection control")) With reference to Fig. 2 (and Fig. 1 as appropriate), media feed control in the first embodiment will be described. In the first embodiment, attention is focused on the feeding of a passbook via the passbook insertion and ejection slot 6 (that is, the feeding operation in the lower inserter unit 2b). The media processing device 1 is capable of processing passbooks and slips of different media lengths, and control of passbooks of different media lengths will be illustrated as an example. When a passbook is inserted, the control unit 20 first performs control to detect the media length.

[0023] Figure 2 is an image diagram for explaining the positional relationship between the medium B at the first position and the first sensor S1 and second sensor S2, where (a) shows the positional relationship at the first medium B1 and (b) shows the positional relationship at the second medium B2. The first medium B1 shown in FIG. 2(a) is a long medium, and its dimension is longer than the inter-sensor distance LS12 between the first sensor S1 and the second sensor S2. The second medium B2 shown in FIG. 2(b) is a short medium, and its dimension is shorter than the inter-sensor distance LS12 between the first sensor S1 and the second sensor S2.

[0024] In the medium length detection control, first, the medium B inserted from the passbook insertion and ejection slot 6 is transported to the first position shown in FIG. 2, and in the process, the second sensor S2 detects the front end of the medium B. The first position shown in FIG. 2 is the initial position for detecting the medium length LB, and may be called the "clamp position" or the like. At the first position, the front end of the medium B in the insertion direction slightly exceeds the second sensor S2 (for example, by a few mm). This allows the control unit 20 to determine the front end position of the medium B. The rear end of the first medium B1 in the insertion direction at the first position is closer to the front side of the device (discharge direction side) than the first sensor S1. On the other hand, the rear end of the second medium B2 at the first position is closer to the back side of the device (insertion direction side) than the first sensor S1.

[0025] Next, the first sensor S1 detects the presence of medium B at the first position. Then, as shown in FIG. 2(a), when the first sensor S1 detects medium B (i.e., when the first medium B1 is long and its trailing end is on the ejection direction side of the first sensor S1), medium B is transported in the insertion direction and the trailing end of medium B is detected by the first sensor S1. On the other hand, as shown in FIG. 2(b), when the first sensor S1 does not detect medium B (i.e., when the second medium B2 is short and its trailing end is on the insertion direction side of the first sensor S1), medium B is transported in the ejection direction until the first sensor S1 detects medium B, and then medium B is transported in the insertion direction and the trailing end of medium B is detected by the first sensor S1. In this way, the control unit 20 determines the trailing end position of medium B.

[0026] Then, the control unit 20 calculates the medium length LB of the medium B based on the determined leading end position and trailing end position. For example, the medium length LB is calculated by "medium length LB = leading end position - trailing end position". After the medium length detection control is completed, the control unit 20 transports the medium B in the insertion direction and performs processing by the printing unit 3 and the auto turn page unit 4.

[0027] (Regarding discharge control before medium length detection according to the first embodiment) 2 to 4 (and also FIG. 1 as appropriate), the discharge control before medium length detection in the first embodiment will be described. The discharge control is performed, for example, when a transaction is stopped (cancelled) before detection of the medium length starts.

[0028] In the discharge control before the detection of the medium length, the control unit 20 first transports the medium B to the first position shown in FIG. 2, and in the process, the second sensor S2 detects the leading end of the medium B. Up to this point, it is the same as the medium length detection control. At the first position, the leading end of the medium B slightly exceeds the second sensor S2 (for example, by a few mm). This allows the control unit 20 to determine the leading end position of the medium B. Note that, although it was stated above that at the first position, the leading end of the medium B slightly exceeds the second sensor S2, the distance that the medium B is transported after the sensor S2 detects the leading end of the medium B is determined according to the position of the sensor S2. For example, if the sensor S2 is located closer to the device than the position shown in FIG. 2, the first position may be transported to a position, for example, a few centimeters beyond the sensor S2.

[0029] The control unit 20 may stop the medium B at the first position and inquire of the operator whether there is an instruction to cancel the transaction. For example, with the medium B stopped at the first position, the display unit may display a screen having a button for canceling the transaction. Next, as shown in FIG. 3, the control unit 20 transports the medium B from the first position to the second position before ejection so that the leading edge of the medium B is at the position of the second sensor S2. The transport from the first position to the second position is performed for all the media B regardless of the medium length LB. FIG. 3 is an image diagram for explaining the positional relationship between the medium B and the first sensor S1 and the second sensor S2 at the second position, where (a) shows the positional relationship for the first medium B1 and (b) shows the positional relationship for the second medium B2. As shown in FIG. 3, at the second position, the leading edges of the first medium B1 and the second medium B2 are both aligned at the position of the second sensor S2.

[0030] The control unit 20 transports the medium B to the second position, for example, by transporting the medium B in the discharge direction by a predetermined distance. The predetermined distance here is the difference between the position of the leading edge of the medium B at the first position and the position of the second sensor S2. The control unit 20 may also transport the medium B to the second position by transporting the medium B until the second sensor S2 is turned OFF (no medium).

[0031] The control unit 20 checks the detection result of the first sensor S1 when the medium B is in the second position, and conveys the medium B to a discharge position based on the detection result. For example, when the detection result of the first sensor S1 is ON (medium present), it can be determined that the first medium B1 is longer than the sensor distance LS12 between the first sensor S1 and the second sensor S2 (see FIG. 3(a)), so the control unit 20 discharges the first medium B1 to a first discharge position suitable for the long first medium B1 (see FIG. 4(a)). On the other hand, when the detection result of the first sensor S1 is OFF (medium absent), it can be determined that the second medium B2 is shorter than the sensor distance LS12 between the first sensor S1 and the second sensor S2 (see FIG. 3(b)), so the control unit 20 discharges the second medium B2 to a second discharge position suitable for the short second medium B2 (see FIG. 4(b)). Note that Figure 4 is an image diagram for explaining the ejection position of the medium during ejection control, where (a) shows the first ejection position corresponding to the first medium B1, and (b) shows the second ejection position corresponding to the second medium B2.

[0032] When discharging medium B to a position where the operator can easily grasp it, the discharge distance of medium B from the passbook insertion and discharge opening 6 becomes an issue, and for example, the distance from the passbook insertion and discharge opening 6 to the rear end of medium B at the discharge position is set to a standard value (or more) that makes it easy to grasp. If the distance from the passbook insertion and discharge opening 6 to the rear end of the first medium B1 at the first discharge position and the distance from the passbook insertion and discharge opening 6 to the rear end of the second medium B2 at the second discharge position are set to be the same, the second discharge distance for transporting the second medium B2 from the second position to the second discharge position will be longer than the first discharge distance for transporting the first medium B1 from the second position to the first discharge position. In this case, the position of the front end of the first medium B1 at the first discharge position is different from the position of the front end of the second medium B2 at the second discharge position.

[0033] Assume that the medium length LB of medium B handled by the media processing device 1 is known. In this case, it is preferable to register in advance the discharge distance according to the classification of medium B, and the control unit 20 transports medium B from the second position according to the registered discharge distance. For example, a first discharge distance is registered in association with a long first medium B1, and a first discharge distance is registered in association with a short second medium B2.

[0034] As described above, in the first embodiment, the media B can be divided into two categories, the first medium B1 with a long medium length LB and the second medium B2 with a short medium length LB, and each medium B can be discharged to an appropriate discharge position. Therefore, when discharging the long first medium B1, it is possible to prevent the medium from dropping due to an excessive discharge amount, and further, when discharging the short second medium B2, it is possible to prevent the medium from being difficult to grasp due to an excessive discharge amount.

[0035] [Second embodiment] In the first embodiment, the medium length LB was determined to be long or short based on the sensor distance LS12 between the first sensor S1 and the second sensor S2, and the medium B was divided into two sections and each section was discharged to an appropriate discharge position. In the second embodiment, three sensors S are used to separate the media B into three sections and discharge each section to an appropriate discharge position.

[0036] Fig. 5 is a schematic diagram of the inserter unit 102 according to the second embodiment. As shown in Fig. 2, a first sensor S1, a second sensor S2, and a third sensor S3 are installed on the insertion / ejection transport path 9b of the inserter unit 102 according to the second embodiment. The third sensor S3 is installed between the first sensor S1 and the second sensor S2.

[0037] (Regarding discharge control before medium length detection according to the second embodiment) The discharge control before medium length detection in the second embodiment will be described with reference to Figures 6 and 7. The discharge control is performed, for example, when a transaction is stopped (cancelled) before detection of the medium length starts.

[0038] The first medium B1 shown in FIG. 6(a) is a long medium, and the medium length LB1 is longer than the inter-sensor distance LS12 between the first sensor S1 and the second sensor S2. The second medium B2 shown in Figure 6 (b) is a medium of medium length, with the medium length LB2 being shorter than the sensor-to-sensor distance LS12 between the first sensor S1 and the second sensor S2, and the medium length LB2 being longer than the sensor-to-sensor distance LS23 between the third sensor S3 and the second sensor S2. A third medium B3 shown in FIG. 6(c) is a short medium, and its medium length LB3 is shorter than the inter-sensor distance LS23 between the third sensor S3 and the second sensor S2. In other words, the relationship between the medium lengths LB of the first medium B1, the second medium B2, and the third medium B3 is "medium length LB3<medium length LB2<medium length LB1."

[0039] As shown in Fig. 6, the control unit 20 transports the medium B from the first position to the second position before ejection so that the leading edge of the medium B is at the position of the second sensor S2. Transport from the first position to the second position is performed for all media B regardless of the medium length LB. Fig. 6 is an image diagram for explaining the positional relationship between the medium B and the first sensor S1, the second sensor S2, and the third sensor S3 at the second position, where (a) shows the positional relationship for the first medium B1, (b) shows the positional relationship for the second medium B2, and (c) shows the positional relationship for the third medium B3.

[0040] The control unit 20 transports the medium B to the second position, for example, by transporting the medium B in the discharge direction by a predetermined distance. The predetermined distance here is the difference between the position of the leading edge of the medium B at the first position and the position of the second sensor S2. The control unit 20 may also transport the medium B to the second position by transporting the medium B until the second sensor S2 is turned OFF (no medium).

[0041] The control unit 20 determines the classification of the medium B to be discharged by checking the detection results of the first sensor S1 and the third sensor S3 when the medium B is in the second position, and transports the medium B to a discharge position based on the determined classification. For example, when the detection results of the first sensor S1 and the third sensor S3 are both ON (media present), it can be determined that the first medium B1 is longer than the sensor distance LS12 between the first sensor S1 and the second sensor S2 (see Figure 6(a)), and the control unit 20 ejects the first medium B1 to a first ejection position suitable for the long first medium B1 (see Figure 7(a)).

[0042] Furthermore, when the detection result of the first sensor S1 is OFF (no medium) and the detection result of the third sensor S3 is ON (medium present), it can be determined that the second medium B2 is shorter than the sensor-to-sensor distance LS12 between the first sensor S1 and the second sensor S2 and longer than the sensor-to-sensor distance LS23 between the third sensor S3 and the second sensor S2 (see Figure 6(b)), so the control unit 20 ejects the second medium B2 to the second ejection position suitable for a medium-length second medium B2 (see Figure 7(b)).

[0043] Furthermore, when the detection results of the first sensor S1 and the third sensor S3 are both OFF (no medium), it can be determined that the third medium is shorter than the sensor distance LS23 between the third sensor S3 and the second sensor S2 (see Figure 6(c)), so the control unit 20 ejects the third medium B3 to a third ejection position suitable for short third medium B3 (see Figure 7(c)). Figure 7 is an image diagram to explain the ejection position of the medium in ejection control, where (a) shows the first ejection position corresponding to the first medium B1, (b) shows the second ejection position corresponding to the second medium B2, and (c) shows the third ejection position corresponding to the third medium B3.

[0044] As described above, in the second embodiment, the medium B can be divided into three categories: the first medium B1 with a long medium length LB, the second medium B2 with a medium length, and the third medium B3 with a short medium length LB, and each medium B can be discharged to an appropriate discharge position. Similarly, by increasing the number of sensors S mounted on the inserter unit 102, it is possible to set the ejection positions in more detail, such as four or five divisions.

[0045] [Variations] In each embodiment, the medium processing device 1 has been described as being a bankbook slip printer, but the present invention can be applied to any device that processes medium B, not just a bankbook slip printer.

[0046] In addition, in each embodiment, the leading edge of medium B is set to the position of second sensor S2 as the second position for determining medium length LB, but the second position can be another position other than the position of second sensor S2. For example, in a device that virtually manages the position of the leading edge of medium B using the number of motor pulses or the like, the second sensor S2 does not need to be physically implemented, and the transport target position can also be found virtually.

[0047] Also, in each embodiment, a method was described in which the medium B is once transported from the first position, which is the clamp position, to the second position so that the leading edge of the medium B is at the position of the second sensor S2, and then the discharge position of the medium B is controlled based on the detection result of the first sensor S1 at the second position. In this way, by using the detection state of the first sensor S1 at the second position, which is closer to the passbook insertion and discharge slot 6 than the first position, it is possible to arbitrarily set the length (the length from the second position to the first sensor S1) that serves as the standard for dividing the medium B. In other words, since the first position, which is the clamp position, is not necessarily a position suitable for dividing the medium B to be discharged, the length from the first position to the first sensor S1 may not be suitable as the standard for dividing the medium B to be discharged. In that case, when the medium B is divided using the detection state of the first sensor S1 at the first position, the medium B cannot be properly discharged. For example, when the first position is much further back than the sensor S2, it is assumed that the medium B is divided using the detection state of the first sensor S1 at the first position. In this case, the length used as the standard for classifying media B (the length from the first position to the first sensor S1) becomes quite long. If there are differences in length among the short media B and the ejection distance for all short media B is set based on a relatively short medium B among the short media B, when a relatively long medium B among the short media B is ejected, the medium B may extend too far outside the device, causing the medium B to fall outside the device.

[0048] Furthermore, when the first position is approximately the same position as the sensor S2 (when the length from the first position to the first sensor S1 is suitable as a criterion for classifying the medium B), the discharge position of the medium B may be controlled at the first position based on the detection result of the first sensor S1 without transporting the medium B from the first position to the second position. That is, when the medium is inserted and then transported to the first position on the insertion / ejection transport path and then ejected, if the detection result of the first sensor S1 at the first position is ON (medium present), it can be determined that the first medium B1 is longer than the sensor distance LS12 between the first sensor S1 and the second sensor S2, and the control unit 20 ejects the first medium B1 to a first ejection position suitable for the long first medium B1. On the other hand, if the detection result of the first sensor S1 is OFF (medium absent), it can be determined that the second medium B2 is shorter than the sensor distance LS12 between the first sensor S1 and the second sensor S2, and the control unit 20 ejects the second medium B2 to a second ejection position suitable for the short second medium B2.

[0049] Also, in each embodiment, the discharge control in the lower inserter unit 2b has been described with a focus on the taking in of the passbook via the passbook insertion and discharge slot 6. However, the present invention can be realized in the upper inserter unit 2a as well by adding a sensor S for determining the medium length LB. Even if the sensor S is not added, the second position may be virtually set as described above, the leading edge of medium B may be aligned to the virtual second position using the number of motor pulses or the like, and the discharge position may be determined by detecting medium B at the second position with the fourth sensor S4.
