Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bankbook handling apparatus and method for setting a handling medium such as a bankbook in an insertion port, sucking to a printing position, and performing a printing process, etc. And a bankbook handling method having a function of detecting a skew amount of a medium.
[0002]
[Prior art]
Conventionally, in a bankbook handling apparatus, a medium is set and conveyed to a printing position by a conveyance roller. However, in this case, when the medium setting state becomes an oblique state, there is a problem that the print position is also obliquely printed.
Therefore, it is necessary to prevent the medium from being inclined in the medium set state.
[0003]
As a conventionally proposed technique, for example, in the one described in Japanese Patent Laid-Open No. 9-39322 (hereinafter referred to as “system A”), an alignment roller that presses and aligns a medium against a reference guide for alignment, and a medium A transport roller that is separate from the transport roller is used. However, this requires extra parts and it is difficult to reduce the space.
[0004]
Further, for example, in the device described in Japanese Patent Laid-Open No. 5-97290 (hereinafter referred to as method B), since the sensor for detecting the medium is not arranged, it is detected whether or not the medium is actually aligned. In addition, there is no specific description of how the plate-like stop plate operates. The contents of the patent of US Pat. No. 5,188,471 are the same as those described above.
[0005]
Further, for example, the one described in JP-A-5-116406 (hereinafter referred to as method C) includes a means for detecting a difference in the thickness of the medium and a gap adjusting mechanism, and has a complicated structure. ing. I want to simplify the structure more.
[0006]
Further, for example, in the device described in Japanese Patent Application Laid-Open No. 2000-302282 (hereinafter referred to as method D), the pressing force is adjusted by a motor and the guide is opened and closed by a solenoid, so that a separate and independent driving device is required. It has a complicated structure. Also, booklets such as bankbooks are not considered, and only single sheets are considered. Note that those described in Japanese Patent Laid-Open No. 2000-309441, Japanese Patent Laid-Open No. 2000-309449, or W000 / 63098 are exactly the same as the method D described above.
[0007]
For example, in the one described in Utility Model Registration No. 2508855 (hereinafter referred to as “method E”), the auxiliary roller for abutting the medium against the paper stopper for alignment and the roller for conveying the medium are not the same, and dedicated alignment is performed. Auxiliary rollers are arranged separately. Further, there is no arrangement of a sensor for detecting the medium, and therefore it cannot be detected by the sensor whether or not the medium is actually aligned.
[0008]
Further, for example, in US Pat. No. 5,088,848 (hereinafter referred to as method F), the alignment roller that presses and aligns the medium against the reference guide for alignment and the roller that conveys the medium are not the same, and a dedicated alignment roller is used. Separately arranged, and the pressing direction of the medium is arranged in two directions, ie, the forward direction and the left end direction, respectively, and a complicated mechanism is formed.
[0009]
Further, for example, in US Pat. No. 5,566,932 (hereinafter referred to as method G), since there is no sensor for detecting the medium, it is not possible to detect whether the medium has actually been matched. Further, there is no switching mechanism between the roller press when aligning the medium and the roller press when transporting the medium, and the roller press at the time of alignment and transport is the same.
[0010]
For example, in US Pat. No. 6,011,948 (hereinafter referred to as method H), there is no mechanism for switching between roller pressing when aligning the medium and roller pressing when transporting the medium, and roller pressing during alignment and transport. Are the same. Further, booklets such as passbooks are not considered and are limited to a continuous paper alignment mechanism.
[0011]
For example, in the one described in US Pat. No. 6,152,628 (hereinafter referred to as method I), the roller for aligning the medium is a dedicated roller that presses against the guide and is different from the roller for transporting. Further, it does not include a roller pressing switching mechanism. Furthermore, the booklet such as a passbook is not considered, and is a single sheet alignment mechanism.
[0012]
Further, for example, a device described in Japanese Patent Application Laid-Open No. 6-71961 (hereinafter referred to as method J) has proposed a device that arranges a medium at a fixed position by a complicated mechanism method.
[0013]
Further, for example, a reference guide described in Japanese Patent Publication No. 61-206680 (hereinafter referred to as method K) has two rollers coaxially as a medium feeding mechanism in the direction perpendicular to the medium insertion direction before magnetic reading. A media gathering mechanism has been proposed. This method K is effective for a passbook that is thick paper and does not have a long length in the suction direction. However, a thin slip such as an A4 size cannot be brought to the reference guide in a short time.
[0014]
Further, for example, in the one described in JP-A-1-242355 (hereinafter referred to as “method L”), the medium nipping / clamping release of the paper discharge roller to the outside of the medium is selectively operated, and the outside of the apparatus is It has been proposed to ensure stability against external forces on the medium. However, this mechanism is capable of handling continuous paper on rolls, and no consideration is given to bringing the passbook / slip cut paper to the reference guide.
[0015]
Further, for example, in the one disclosed in Japanese Patent Laid-Open No. 5-201078 (hereinafter referred to as “method M”), the medium feeding mechanism releases the medium pressure in the direction perpendicular to the reference guide and in the medium thickness direction before magnetic reading. It has been proposed that a width-shifting wheel arranged so as to operate also in the direction in which the recording medium is pressed against the reference guide. This method M, like the method K, is effective for a passbook that is thick paper and does not have a long length in the suction direction. However, a thin slip such as an A4 size, for example, is brought to the reference guide in a short time. There are no drawbacks.
[0016]
Further, for example, the one described in Japanese Patent Application Laid-Open No. 9-510409 (hereinafter referred to as system N) proposes a mechanism for aligning the medium tilt by rotating control around a stationary point on the set medium as a printer with an alignment mechanism. Has been. This is a complicated mechanism system in which the rotation control mechanism is arranged on the left and right sides to make both directions clockwise and counterclockwise.
[0017]
[Problems to be solved by the invention]
Regarding the method A, it is desirable to use the same roller as the aligning roller that presses and aligns the medium against the reference guide for aligning and the roller that conveys the medium because there is an advantage that the mechanism is not complicated. In addition, for method B, it is necessary to provide a sensor in order to detect whether or not the medium is aligned, and it is also necessary to check whether or not the alignment of the medium is disturbed. Further, for the method C, the means for detecting the thickness of the medium needs to be further simplified because the structure is complicated. For method D, it is desirable that pressure switching and opening / closing of the guide are not separately arranged but simplified. It is also desirable to be able to handle booklets such as bankbooks.
[0018]
In the system E as well, it is preferable that the alignment roller that presses and conveys the medium and the roller that conveys the medium are not separately arranged on the reference guide for alignment, and the pressure adjustment is performed so that the same roller is also used. In addition, it is desirable to provide a sensor for confirming the alignment of the medium and for confirming whether the alignment is disturbed. As for the system F, it is desirable to operate the roller for pressing and aligning the medium and the medium transporting roller with the same roller, and it is desired that the pressing direction is simple and the mechanism is simple. For system G, it is desirable to provide a sensor to confirm whether the medium is aligned, and a mechanism for switching between roller pressing when aligning the medium and roller pressing when conveying the medium It is desirable to equip. This is also true for method H and method I.
[0019]
Therefore, an object of the present invention is to solve these conventional problems, and to arrange a medium of a variety of passbooks and slips set obliquely at a fixed position of a reference guide, and then a high-precision and simple mechanism for sucking the medium And inexpensive passbook handling apparatus and method.
[0020]
[Means for Solving the Problems]
In order to achieve the above object, the passbook handling apparatus according to the present invention, when the medium is set at an incorrect position in the insertion slot, the medium is conveyed by a conveying roller comprising a driving roller and a pressing roller each having a driving force. When transporting to the printing position, the pressure applied to the medium is controlled by a solenoid, the reference guide serving as a reference in the direction perpendicular to the transport direction is lowered, and the passbooks are transported and pressed against the reference guide for alignment. The operation ends when the plurality of medium inhalation sensors have a predetermined pattern. After that, the passbooks set in various states are always aligned at a certain position before inhalation to the printing position by detecting whether the passbooks are matched within the standard range by the sensor. Therefore, the print position processed thereafter can always be a print position with no misalignment.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below in detail with reference to the drawings.
FIG. 1 is an external perspective view of a bankbook handling apparatus showing an embodiment of the present invention.
Here, an external view of the apparatus as viewed obliquely from the front and a partial perspective view of the inside thereof are also shown. First, the configuration that performs a functionally important function in the bankbook handling apparatus 40 of the present invention will be mainly described. The handling medium is inserted into the conveyance path formed by the upper conveyance path surface 5 and the lower conveyance path surface 3 in the direction of the arrow 38, that is, from the front surface of the bankbook handling apparatus 40.
The medium of the bankbook handling apparatus 40 includes a medium mainly closed in a booklet form such as a bankbook, and ordinary ordinary paper such as a form.
[0022]
The overall structure will be described. The reference guide 2 is disposed in front of the print head 14 and behind the pressure roller 11. The reference guide 2 is an alignment means for causing the medium to collide with the reference guide and adjusting it in a state parallel to the print head in order to prevent printing in an oblique state, and then facing the print head. In FIG. 1, only a part of the reference guide 2 is shown, but actually, the reference guide 2 is incorporated in a guide opening / closing mechanism described later, and this guide opening / closing mechanism is a roller clamping force control mechanism. Is working with.
[0023]
A position sensor 10 is disposed at the lower center of the reference guide 2, and a front sensor 8 is disposed on the front surface of the reference guide 2. When the medium is inserted in the direction of the arrow 38, the driving roller 13 rotates on the lower surface, and the pressing roller 11 rotates about the shaft 12 on the upper surface. The medium is conveyed between the driving roller 13 and the pressing roller 11. A lateral sensor 7 for measuring the lateral length of the medium is arranged, and a position sensor 9 and a presence sensor 26 for detecting the presence or absence of the medium are arranged at the position of the pressing roller 11. A print head 14 and a support rail 15 that supports the print head 14 are provided behind the reference guide 2.
[0024]
As described above, the sensors for detecting the medium inserted or conveyed include the lateral sensor 7, the front sensor 8, the presence sensor 26, the position sensor 9, and the position sensor 10. The position sensors 9 and 10 are installed in the vicinity of the reference guide 2 and detect that there is a medium when dark and no medium when writing. The mechanism that constitutes the bankbook handling device 40 is roughly divided into a transport mechanism that transports the medium in the X direction from the front to the rear, an alignment mechanism that corrects skew of the medium and aligns (or transports) the medium in the X direction, There is a printing mechanism for printing on a medium.
[0025]
The transport mechanism includes a transport roller that is in direct contact with the medium and is made of an elastic material such as rubber. The A drive roller 13 and the B drive roller 16 (see FIG. 2) are transported in contact with the bottom of the medium, from above the medium. It consists of pressing rollers 11 and 33 (see FIG. 2) that convey in contact with each other. Usually, the medium is sandwiched between the A driving roller 13 and the pressing roller 11 and conveyed to the print head 14 as a printing unit.
[0026]
The alignment mechanism is a guide opening / closing mechanism (not shown) that opens and closes a reference guide 2 that serves as a reference for aligning the medium, and adjusts the clamping force of the pressing rollers 11 and 33 (not shown) to bring the medium to the reference guide 2. It comprises a roller clamping force control mechanism (not shown). Specifically, the medium is brought close to the reference guide 2 by the rotation of a pressing roller 11 that also serves as a closing roller, which will be described later, and the medium is aligned.
The reference guide 2 itself has been used in the past. However, as described above, the roller holding force control mechanism that adjusts the holding force and the roller that abuts the conveyance roller and the reference guide are the same roller. Different from conventional ones.
[0027]
In the print mechanism, a print carrier (not shown) on which the print head 14 supported by the support rail 15 is mounted moves in the left-right direction, and printing is performed on the medium by the print head 14.
[0028]
2 is a side sectional view and an upper sectional view of the internal configuration of the bankbook handling apparatus in FIG.
FIG. 2A shows an internal configuration viewed from the side of the bankbook handling apparatus 40, and particularly shows a medium transport system. The print medium is inserted and set from the medium suction port 36 and is conveyed in the direction of the arrow 38 along the conveyance path formed by the guides of the lower conveyance path surface 3 and the upper conveyance surface 5. The medium is conveyed between the A driving roller 13 and the pressing roller 11 and between the B driving roller 16 and the pressing roller 33, whereby the rotational power is transmitted to the medium by the frictional force between the medium and the roller, and the medium is conveyed.
[0029]
The A driving roller 13 and the B driving roller 11 are connected to the conveyance motor 31 via the belt 32 and the gear 20. The pressure rollers 11 and 33 are connected to the A drive roller 13 and the B drive roller 16 by a gear 21 and b gear 22 (see FIG. 3) and are driven through a joint 23 (see FIG. 3). The power of the transport motor 31 is transmitted to the A drive roller 13 and the B drive roller 16, and finally the rotational power to the medium is transmitted to carry the medium.
[0030]
FIG. 2B shows an internal configuration viewed from the upper surface of the bankbook handling apparatus 40, and particularly shows a medium printing system. When the printing medium is conveyed to the printing position, the printing motor 48 is driven, and the print carrier 46 mounted with the print head 14 supported by the support rail 15 (see FIG. 1) via the belt 47 is moved in the horizontal direction. Move. Printing is performed on the medium by the print head 14 while the print carrier 46 moves. Here, 49 is a pulley, 50 is a print sensor, 51 is a sensor, and 51A is a blade (shielding plate).
[0031]
FIG. 3 is a view showing a roller clamping force control mechanism for controlling the roller clamping force of the bankbook handling apparatus in FIG.
Hereinafter, the function of controlling the roller clamping force will be described with reference to FIG.
FIG. 3 shows a state where the medium is sandwiched between the pressing roller 11 and the A driving roller 13. The pressing roller 11 is attached to a shaft 12 (see FIG. 1) extending in the lateral direction of the bankbook handling apparatus 40. And the shaft 25 which fixed the leaf | plate spring 24 for applying a press to this shaft 12 is arrange | positioned. By rotating the shaft 25, the shaft 12 can be controlled to be pressed or released.
[0032]
The shaft 25 and the solenoid 18 are connected by a link mechanism. The shaft 25 is always pulled by a spring 42 in the direction of an arrow 41 (see FIG. 4). A pressure is transmitted from the shaft 25 to the pressing roller 11 by the spring 42 to clamp the medium. By pulling the solenoid 18, the transmission of the pressure from the shaft 25 to the pressure roller 11 is blocked, and the clamping force to the pressure roller 11 is controlled. By controlling the solenoid 18, the pressure applied to the shaft 12 is changed, and the clamping force with which the medium is clamped between the pressing roller 11 and the A driving roller 13 is controlled.
As is apparent from FIGS. 3 and 1, the pressing roller 11 and the A driving roller 13 sandwich the medium at a position slightly shifted from the same position. Reference numerals 7 to 10 denote sensors, 44 is a guide shaft, 24 is a leaf spring, 43 is a bracket, 2 is a reference guide, and 31 is a motor.
[0033]
FIG. 4 is a partial side view of a guide opening / closing mechanism that is a function for opening / closing a reference guide for aligning a medium such as a passbook with a reference position.
3 shows a mechanism for controlling the reference guide 2 to a closed state (2A) or an open state (2B) outside the conveyance path by the guide shaft 44, the shaft 25, and the bracket 43 shown in FIG.
The mechanism for opening and closing the reference guide 2 includes a bracket 43 attached to the shaft 25, the reference guide 2, and a guide shaft 44 for fixing the reference guide 2.
The roller clamping force control mechanism and the mechanism for opening and closing the guide are operated by the same solenoid 18 (see FIG. 3), and the operation is linked between the roller clamping force control mechanism and the mechanism for opening and closing the guide.
[0034]
The solenoid 18 of the above-described roller clamping force control mechanism is released, and the shaft 25 is rotated. Thereby, the bracket 43 attached to the shaft 25 rotates in the direction of the arrow 41, and pushes the reference guide 2 out of the conveyance path (state of the reference guide 2B). As a result, the reference guide 2 in the transport path is opened. At this time, the interlocking roller clamping force control mechanism is in a strong clamping force state, and the medium is in a transport state.
When the solenoid 18 is pulled (PULL) and the bracket 43 attached to the shaft 25 does not push up the reference guide 2 and is in the conveyance path, the reference guide 2 is in a closed state (state of the reference guide 2A). . At this time, the interlocking roller clamping force control mechanism is in a weak clamping force state, and the medium is aligned with the reference guide 2.
[0035]
By operating the roller clamping force control mechanism and the mechanism for opening and closing the reference guide 2 by the same solenoid 18, it can be operated instantaneously, unlike the operation by the motor, and it operates by the same solenoid 18. Therefore, compared with the case where each actuator is mounted and operated, the number of parts can be greatly reduced, and the present mechanism can be mounted in a small space. Reference numeral 24 denotes a leaf spring.
[0036]
FIG. 5 is a control block diagram of the bankbook handling apparatus in FIG.
As shown in FIG. 5, the control unit 27 receives the report of the detection state from each sensor and controls each drive circuit. The control unit 27 performs control processing by executing a program stored in a ROM 272 in which the CPU 273 is built. Control is executed by referring to the table and data stored in the RAM 271.
[0037]
When the control unit 27 receives the detection signal information from the front sensor 7, the lateral sensor 8, the presence sensor 26, the position sensor 9, the position sensor 10, the print sensor 50, and the sensor 51, the transport motor drive circuit 28 for transporting the medium. The printing motor drive circuit for driving the solenoid 18 by moving the print carrier by driving the conveying motor 31 and controlling the solenoid driving circuit 30 for controlling the pressing force of the pressing roller and opening / closing the reference guide 2. The printing motor 48 is driven by 52.
[0038]
FIG. 6 is a top partial view of the passbook handling apparatus according to the present invention when the sensor of the medium alignment determination is detected, and FIGS. 7 and 8 are a flowchart of the medium alignment operation and a medium skew amount detection operation of the present invention. .
The operation in which the apparatus sucks the medium, aligns the medium, conveys it, and performs printing will be described with reference to FIGS. 2, 3, 4, 6, and 7. FIG.
A presence / absence sensor 26 is provided between the medium suction port 36 and the A driving roller 13 to detect the presence / absence of the medium. As described with reference to FIG. 1, the presence sensor 26 detects the medium when the medium covers the presence sensor 26 from the medium suction port 36. When the presence / absence sensor 26 detects the medium in this way, the control unit 27 drives the carry motor 31 by this detection signal (S002).
[0039]
Accordingly, the medium is conveyed in the direction of the arrow 38 in FIG. 1, that is, from the right side (front surface of the bankbook handling device 40) to the left side (rear surface of the bankbook handling device 40) in FIG.
At this time, the solenoid 18 described above is in a pulled state (PULL state) (S001), and the reference guide 2 is in the transport path. Further, the clamping force of the pressing roller 11 is controlled to a weak force.
[0040]
Similarly, position sensors 9 and 10 are provided between the A driving roller 13 and the reference guide 2 as sensors for detecting the medium. The position sensors 9 and 10 detect the medium when the medium conveyed from the medium suction port 36 is pressed against the reference guide 2 and hits the position sensors 9 and 10 (S003).
At this time, the pressure applied to the medium by the pressing roller 11 is weakly controlled by the roller clamping force control, and even if the medium is pressed against the reference guide 2 and conveyed, the medium will not be bent or bent. . By pressing against the reference guide 2, the medium is aligned with the reference guide 2.
[0041]
As described above, when the position sensors 9 and 10 detect the medium, the control unit 27 stops the drive motor 31 (S004).
At this position, the medium is sandwiched between the A driving roller 13 and the pressing roller 11 and the medium is sandwiched with a weak force, but is not sandwiched between the B driving roller 16 and the pressing roller 33.
[0042]
Subsequently, the pressure at which the medium is held by the control unit 27 at the detection position of the position sensors 9 and 10 is controlled to increase the pressure applied by the pressure roller 11 to the medium. In other words, when the solenoid 18 is released (S005), the medium that has been sandwiched between the A driving roller 13 and the pressing roller 11 with a weak force becomes more sandwiched and has a sufficient medium conveying force.
The solenoid 18 is released, and the pressure applied to the medium is increased by the clamping force control mechanism of the pressure roller. At the same time, the guide guide opening / closing mechanism moves the reference guide 2 out of the transport path so as not to collide with the medium transport. Move to.
[0043]
Next, the operation of the medium skew amount detection shown in FIG. 8 is started. As shown in FIG. 6, the state in which the medium is conveyed from the suction port 36 in the direction of the arrow 38 and the medium has advanced to the A position is 45A, and when it further proceeds to the B position, it becomes 45B. Reference numeral 46 denotes a print carrier, 51 denotes a sensor near the print carrier, and 50 denotes a print sensor.
First, the medium is conveyed to position A (S006).
[0044]
At position A, the print motor is driven and the print carrier 46 on which the sensor 51 is mounted is moved until the sensor 51 detects the medium edge of the medium 45A, and the distance t1 from the print sensor 50 to the medium 45A is read (S007). . The medium is conveyed again, and the medium is conveyed to the B position (S008). At position B, the print motor is driven and the print carrier 46 loaded with the sensor 51 is moved until the sensor 51 detects the medium edge of the medium 45B, and the distance t2 from the print sensor 50 to the medium 45B is read (S009). ).
[0045]
The skew angle α1 of the medium 45 is calculated from the difference t3 (t2−t1) between the distances t1 and t2 read from the above and the difference L1 between the A position and the B position. It is determined whether or not the skew angle α1 is equal to or smaller than the allowable skew angle α. If the skew angle α1 is equal to or smaller than the allowable skew angle α, it is determined that the medium is properly aligned, and the next operation is started. On the other hand, if the skew angle α1 is equal to or larger than the allowable skew angle α, it is determined that the medium is not properly aligned, and the medium is ejected without proceeding to the next operation (S010).
[0046]
Since the print head 14 moves along the support rail 15, high-quality printing can be performed at this print position even on a medium such as a passbook.
Then, after this desired printing, the transport motor 31 is driven in the direction opposite to that at the time of suction to transport the medium in the direction of the suction port 36 in FIG.
[0047]
【The invention's effect】
As described above, according to the present invention, in the passbook handling apparatus, the medium can be arranged at the position of the reference guide for a short processing time regardless of variations when set in the insertion slot, and the inhalation The subsequent printing process, passbook magnetic stripe read / write process, etc. can be handled accurately, and there is an effect that a passbook handling apparatus with high accuracy and excellent usability can be realized.
