Description

  The present invention relates to a medium processing apparatus that takes in a medium along a conveyance path and performs a predetermined process, and more particularly, to a medium processing apparatus that includes a mechanism for narrowing the medium to a side portion of the conveyance path.

  At a window of a financial institution or the like, a form processing apparatus is used that accepts a medium such as a passbook or a slip set by an operator and reads an entry, prints it, reads / writes it to a magnetic recording unit, and the like. In particular, in recent years, both passbooks whose specifications such as size and thickness have been determined in advance and slips consisting mainly of a single sheet of paper, such as application forms entered by customers, can be inserted and processed simultaneously. Is increasing. For example, there are some which have respective insertion ports for passbooks and slips, but various internal read / write mechanisms are used in common.

  In such a form processing apparatus, in the process of taking in the medium, a process is performed in which the medium is brought into close contact with the side surface of each conveyance path. By this width adjustment process, the medium take-in angle is made uniform to prevent the internal read / write position from becoming inaccurate. As a mechanism for performing the width-shifting processing of the medium, for example, a method of separately providing a transport roller and a width-shifting roller and switching the rollers during medium insertion or during transport, or a medium For example, there is a method in which an aligner roller having a tapered surface is used for transporting the inside of the roller, and the width is gradually adjusted according to the movement on the transport path.

  The processing in the case where individual rollers for conveyance and width adjustment are provided is performed as follows, for example. First, a stopper that gives a reference position in the conveyance direction of the medium is set on the conveyance path, and the width-adjusting roller is driven to perform the width alignment in a state where the leading portion of the medium is abutted against the stopper. Subsequently, the roller is switched, the stopper is released, and the medium is conveyed inside.

  In addition, after performing the width aligning process, there is also a function that detects the skew amount of the medium using a sensor and retry the width aligning process in an oblique state. For example, in the case of the above example using individual rollers for conveyance and width adjustment, the medium is conveyed to the internal skew detection unit after completion of width alignment, and the amount of skew of the medium is detected by a plurality of optical sensors, etc. To do. If the skew amount exceeds the allowable value, the medium is conveyed in the reverse direction to the original width alignment position, and the width alignment process is performed again.

In addition, as an example of using an aligner roller as the width adjusting mechanism, the aligner roller transports the medium inside, detects the skew amount of the medium with a line sensor on the transport path, and the skew amount exceeds the allowable value. In such a case, there has been a method of further shifting the width by conveying the medium in the reverse direction (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 11-011744 (paragraph numbers [0009] to [0012], FIG. 4)

  By the way, in recent counter processes at financial institutions, the types of slips handled are increasing with the diversification of services. For this reason, the form processing apparatus is also required to process various types of slips having different sizes.

  However, it is not easy to convey all slips of different sizes with a precise width. In particular, in the processing in the case where the above-described individual rollers for conveyance and width adjustment are provided, the width adjustment is performed in a state where the top portion of the medium is abutted against the stopper, and therefore, from the stopper to the roller for width adjustment. The distance is constant. In this case, when the length of the set medium in the conveyance direction is short, the roller comes into contact with the vicinity of the center portion of the medium, so that the width is relatively easily adjusted. However, when the length of the medium in the conveyance direction is long, the roller force acts at a position greatly deviated from the center of the medium, so that there are many cases where the medium is inclined at the time of width adjustment and correct width adjustment cannot be performed. .

  Therefore, such a medium has a large amount of skew after the width adjustment, and it is necessary to repeat the width adjustment processing many times. Alternatively, there are cases where the medium cannot be corrected to the correct angle even if the width adjusting process is repeated.

  Further, in the form processing apparatus, for example, the same motor is used for the transfer of the passbook and the transfer of the slip, for example, the number of parts is reduced, the apparatus cost is reduced, and the installation space of the apparatus is suppressed. Therefore, it is required to realize a mechanism for accurately dealing with slips of various sizes without increasing the number of parts as much as possible.

  The present invention has been made in view of such problems, and even when media having different sizes in the transport direction are set, it is possible to accurately and efficiently perform the width adjustment processing of these media. An object of the present invention is to provide a simple medium processing apparatus.

  In the present invention, in order to solve the above-described problem, in a medium processing apparatus that takes in a medium inserted into an insertion port by an operator into the inside along a transport path and performs a predetermined process, the first medium is loaded by a transport roller. A conveying mechanism that moves along the conveying path; a width-adjusting mechanism that causes the first medium to abut against an abutting member disposed on a side of the conveying path by a width-adjusting roller; and the width-adjusting roller A medium stopper that can be opened and closed on the inner side of the apparatus, and that contacts the inner end of the first medium when closed, and the first medium from the direction of the insertion port A medium insertion detection sensor for detecting whether or not the medium is in contact; and a skew sensor provided on the inner side of the apparatus from the medium stopper to detect the skew amount of the inner end of the first medium. Having the first During the initial insertion of the medium, the first medium inserted through the insertion port is inserted in a state in which both the transport roller and the width adjusting roller are retracted from the transport path and the medium stopper is closed. Is detected by the medium insertion detection sensor, the width-adjusting roller is protruded into the conveyance path, the width-adjusting roller is rotated to perform the width-adjusting operation of the first medium, and the width-adjusting operation is completed. Later, the medium stopper is opened and the conveying roller protrudes into the conveying path, and then the width adjusting roller is retracted from the conveying path, and the conveying roller is rotated to rotate the first medium. When the amount of skew detected by the skew sensor exceeds a permissible value, the medium stopper is kept open while the medium stopper is open. The conveyance roller is reversely rotated to convey the first medium from the alignment operation position at the time of the initial insertion to the alignment re-execution position inside the apparatus, and the alignment roller protrudes into the conveyance path. Then, the conveyance roller is retracted from the conveyance path, the width adjustment roller is rotated, and the width adjustment operation is re-executed.

  In such a medium processing apparatus, when the first roller is inserted into the conveyance path in a state where both the conveyance roller and the width adjusting roller are retracted from the conveyance path and the medium stopper is closed, The end of the medium inside the apparatus abuts against the closed medium stopper, thereby positioning the width. At this time, as the medium insertion detection sensor detects that the first medium has come into contact with the medium stopper, the width adjusting roller of the width adjusting mechanism is brought into a state protruding from the conveyance path and rotated. One medium is brought into contact with the abutting member on the side of the conveyance path, and alignment in the width direction is performed.

  After this width adjustment operation, the medium stopper is opened, the conveyance roller of the conveyance mechanism is projected into the conveyance path, and the width adjustment roller is retracted from the conveyance path. The roller is rotated to convey the first medium into the apparatus. When passing over the skew sensor during the conveyance, the skew amount of the side of the first medium inside the apparatus is detected. When the skew amount exceeds the allowable value, the transport roller is rotated in the reverse direction, and the first medium is transported in the reverse direction to the width alignment re-execution position. At this time, the medium stopper is kept open, so that the first medium can be returned to the installation position of the width adjusting roller.

  The realignment re-execution position is the position inside the device from the realignment operation position at the time of initial insertion, and after the width adjusting roller is in a state protruding from the conveying path at this position, the conveying roller is moved from the conveying path. After the retracted state, the width adjusting roller is rotated, and the width adjusting operation is performed again. Therefore, in the width-shifting operation at the time of initial insertion and re-execution, the width-shifting roller can be brought into contact with a different position with respect to the transport direction of the first medium.

In the medium processing apparatus of the present invention, at the time of initial insertion of the first medium, the width adjusting operation is performed at a position where the side portion inside the apparatus is in contact with the medium stopper. Further, after that, when the skew amount of the first medium is large, the realignment re-execution position is set to the position inside the apparatus from the realignment operation position at the time of initial insertion. As a result, at the time of re-execution of the width alignment, the contact position of the width alignment roller in the transport direction of the first medium can be set to a position different from that at the initial insertion time. Therefore, when media having different sizes are inserted, the contact position of the width adjusting roller can be corrected at the time of re-execution, and more accurate width alignment can be performed. Furthermore, from the start of the width adjustment at the time of initial insertion, the first medium is transported in the reverse direction based on the detection result of the skew feed amount, and after the width alignment is re-executed and completed, the first Since the medium is always held by at least one of the conveying roller and the width-adjusting roller, these operations can be stably performed, and the first medium can be surely width-adjusted.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a principle diagram for explaining the principle of the present invention. FIG. 1A shows the state of the medium processing apparatus when the medium is initially inserted, FIG. 1B shows the state of detecting the skew of the medium, and FIG.

  The medium processing apparatus 1 according to the present invention is an apparatus for carrying a predetermined process by conveying a medium 2 such as inserted paper into the apparatus along a conveyance path 11. In the apparatus, for example, processing such as reading of characters and data from the medium 2 and printing on the medium 2 is performed. FIG. 1 shows a schematic configuration of a cross section in the vicinity of the insertion opening in such a medium processing apparatus 1, and a mechanism for performing the above-described processing inside is omitted.

  As shown in FIG. 1, the medium processing apparatus 1 of the present invention includes transport mechanisms 12 and 13 for transporting the medium 2 along the transport path 11, and a width adjusting mechanism 14 for performing a width adjusting operation on the medium 2. And a medium stopper 15 for restricting the movement of the medium 2 in the direction of the conveyance path 11 and a skew sensor 16 for detecting the skew amount of the medium 2 being conveyed.

  The transport mechanisms 12 and 13 have transport rollers 12a and 13a driven by a power source (not shown), and press rollers 12b and 13b corresponding to these rollers, respectively. Each of these rollers is provided so as to be able to move up and down with respect to the conveyance path 11, and the conveyance rollers 12a and 13a and the corresponding pressing rollers 12b and 13b are brought into contact with the medium 2 to rotate the conveyance rollers 12a and 13a. As a result, the medium 2 is moved in the direction of the conveyance path 11 (left and right direction in the figure).

  The width adjusting mechanism 14 has a width adjusting roller 14a driven by a power source (not shown) different from that for driving the transport mechanisms 12 and 13, and a pressing roller 14b corresponding thereto. These rollers are also provided so as to be able to move up and down with respect to the conveyance path 11, and each medium is brought into contact with the medium 2 and the width adjusting roller 14a is rotated, whereby the medium 2 is moved in the width direction (front and rear in the figure). Direction). The width adjusting mechanism 14 rotates the width adjusting roller 14a to bring the medium 2 into contact with one side surface of the conveying path 11, thereby performing a width adjusting operation for positioning in the width direction during conveyance into the apparatus. Do.

  The medium stopper 15 is provided so as to be openable and closable with respect to the transport path 11 and restricts the movement of the medium 2 toward the inside of the apparatus when closed. The medium stopper 15 is provided on the inner side of the apparatus from the installation position of the width adjusting roller 14a and the pressing roller 14b.

  The skew sensor 16 is provided with the transport path 11 sandwiched between the upper and lower sides, and detects the skew amount of the inside end portion of the medium 2 moving on the transport path 11. The skew sensor 16 is formed by, for example, an optical sensor.

Next, the operation at the time of taking in the medium 2 in the medium processing apparatus 1 of the present invention will be described.
When the medium 2 is inserted, the medium processing apparatus 1 of the present invention first performs a width-shifting operation of the medium 2, aligns the medium 2 with respect to the width direction of the transport path 11, and then transports the medium 2 into the apparatus. Further, the amount of skew of the medium 2 is detected during the conveyance, and when this value exceeds the allowable value, the width adjusting operation for the medium 2 is executed again. The position of the medium 2 at the time of re-execution of the width adjusting operation is different from that at the time of the width adjusting operation at the initial insertion.

  First, as shown in FIG. 1A, the medium 2 is inserted into the transport path 11 by the operator with the medium stopper 15 closed. At this time, the medium 2 is inserted until the inner end of the apparatus comes into contact with the medium stopper 15, and the width adjusting mechanism 14 performs the width adjusting operation at this position.

  When the width shifting operation is completed, the medium stopper 15 is opened as shown in (B), and the medium 2 is transported to the skew sensor 16 side by the transport mechanisms 12 and 13. Then, when the medium 2 passes over the skew sensor 16, the skew amount of the medium 2 is detected. As a result of this detection, if the skew amount is within an allowable value, the medium 2 is further transported into the apparatus and a predetermined process is performed.

  If the detected skew amount exceeds the allowable value, the medium 2 is transported in the reverse direction by the transport mechanism 12. Then, as shown in (C), the medium 2 is stopped at a position on the inner side of the apparatus with respect to the position for performing the width alignment when the medium 2 is initially inserted, and the width alignment operation is performed again by the operation of the width alignment mechanism 14. Thereafter, the medium 2 is again conveyed to the inside by the conveying mechanism 12 to detect the skew amount, and when the skew amount is large, the medium 2 is further conveyed in the reverse direction, and the width shifting operation is executed. Note that the medium stopper 15 remains open after the width-shifting operation at the time of initial insertion is completed.

  By the way, when the width of the medium 2 is shifted, it is desirable that the width-shifting roller 14a and the pressing roller 14b are brought into contact with the vicinity of the center portion in the insertion direction of the medium 2. However, in the above-described medium processing apparatus 1, the width-shifting operation at the time of initial insertion is executed at a position where the leading end of the medium 2 is brought into contact with the medium stopper 15. The distance to the position where each roller contacts the medium 2 is always constant.

  For this reason, for example, when the medium 2 with a short insertion direction is inserted, each roller can be brought into contact with the central portion of the medium 2, but when the longer medium 2 is inserted, each roller However, there is a greater number of cases where the medium 2 does not contact the side part of the transport path 11 correctly because the medium 2 is in contact with a position greatly deviated from the center of the medium 2.

  In the medium processing apparatus 1 of the present invention, as described above, the re-execution position of the width adjusting operation with respect to the medium 2 is a position closer to the inside of the apparatus than the width adjusting operation at the time of initial insertion. As a result, even when each roller comes into contact with a position deviated from the center of the medium 2 in the width-shifting operation at the initial insertion, each roller is brought into contact with the medium 2 in the carry-out direction when the width-shifting operation is re-executed. be able to. Therefore, it is possible to perform the width alignment more accurately on the media 2 having different lengths.

  Next, an embodiment of the present invention will be specifically described. Here, a description will be given by taking as an example a form processing apparatus that is installed at a counter of a financial institution or the like and that performs processing such as reading and printing of characters and data by inserting a passbook and a slip. In the following explanation, a passbook means a booklet of a predetermined size in which a plurality of papers are closed, whereas a form is filled with various information by customers and window operators. It is assumed that there are a plurality of types of paper that are mainly one sheet and have different sizes.

FIG. 2 is a cross-sectional view showing a schematic configuration of the entire form processing apparatus according to the embodiment of the present invention.
As shown in FIG. 2, the form processing apparatus 100 includes separate conveyance paths 101 and 102 for slips and passbooks in the vicinity of the insertion slot. These conveyance paths 101 and 102 merge with the common conveyance path 103 inside. The form processing apparatus 100 includes a width-shifting mechanism unit 100a, a skew feeding detection unit 100b, an MS (magnetic stripe) unit 100c, a scanner 100d, and a page turning mechanism unit along the conveyance paths 101 and 102 and the common conveyance path 103. 100e, a printing mechanism unit 100f, and a cover turning mechanism unit 100g are provided. The width adjusting mechanism 100a is driven by using one width adjusting motor 104 as a power source. Although not shown, a transport mechanism unit for transporting slips and passbooks is provided along the transport paths 101 and 102 and the common transport path 103, and this transport mechanism unit powers one transport motor 105. Driven as a source.

  The width alignment mechanism unit 100a performs width alignment by using the rollers to shift the slips and passbooks inserted in the conveyance paths 101 and 102, respectively. The skew detection unit 100b detects the skew amount of slips and passbooks transported from the transport paths 101 and 102 to the common transport path 103 using an optical sensor. The MS unit 100c reads the information recorded on the magnetic stripe attached to the passbook.

  The scanner 100d optically reads information such as characters and symbols entered in the slip and passbook on the common conveyance path 103. The page turning mechanism unit 100e turns pages of paper closed in a passbook on the common conveyance path 103. The printing mechanism unit 100f prints characters and the like on the page opened by the page turning mechanism unit 100e. The cover turning mechanism unit 100g has a function of turning only a cover having a relatively large thickness among papers closed in the passbook.

Both the width adjusting motor 104 and the conveying motor 105 are stepping motors.
In the form processing apparatus 100 having such a configuration, the slips and passbooks inserted into the transport paths 101 and 102 are width-justified by the width-justification mechanism unit 100a. Then, when the skew detection unit 100b confirms that the position is correctly aligned in the width direction, it is taken into the apparatus. Prior to this import, information on the bankbook is read in advance, for example, in the MS unit 100c.

  For example, after the written information is read by the scanner 100 d, the information is printed by the printing mechanism unit 100 f as necessary, and the slip taken in the inside is discharged through the conveyance path 101. Further, for example, the passbook opens a predetermined page in the page turning mechanism unit 100e and the cover turning mechanism unit 100g, performs printing in the printing mechanism unit 100f, and is discharged through the conveyance path 102.

  By the way, in the form processing apparatus 100, both the slip and the passbook can be simultaneously inserted into the conveyance paths 101 and 102, respectively. As described above, the slip and passbook transport mechanism are driven by the same transport motor 105, so that when both the slip and the passbook are inserted, the transport is alternately performed. Similarly, the width aligning mechanism 100a is driven by the same width aligning motor 104, and the width aligning operation for the slip and the passbook can be performed alternately. Therefore, between the transport paths 101 and 102, when the medium is transported on the one hand, the width aligning mechanism 100a is set on the other hand, and the width aligning operation can be performed.

  As described above, in the form processing apparatus 100, the conveyance motor 105 and the width adjustment motor 104 are shared between the two conveyance paths 101 and 102, so that the slip and the passbook can be inserted at the same time. The number of points is kept to a minimum and the manufacturing cost is reduced, and the installation space for the apparatus is also reduced.

Next, operations in the width adjusting mechanism 100a and the skew detection unit 100b for the slip will be described in detail.
FIG. 3 is a cross-sectional view showing the configuration in the vicinity of the slip and passbook insertion part.

  As shown in FIG. 3, the vicinity of the slip and passbook insertion portion in the form processing apparatus 100 is mainly configured by a lower unit 110, an intermediate unit 120, and an upper unit 130. A slip conveyance path 101 is disposed between the upper unit 130 and the intermediate unit 120, and a passbook conveyance path 102 is disposed between the intermediate unit 120 and the lower unit 110. Note that the direction from the left to the right in the drawing is the insertion direction of each medium, and a skew detection unit 100b (not shown) is arranged along the common conveyance path 103 at the rear stage of each unit.

  Each unit is provided with a conveyance mechanism and a width adjusting mechanism for each of the slip and the passbook. The intermediate unit 120 is provided with conveying rollers 121a and 121b as slip and passbook conveying mechanisms, and width adjusting rollers 122a and 122b as width adjusting mechanisms, respectively. The lower unit 110 is provided with pinch rollers 111 and 112 that press the conveying roller 121b and the width adjusting roller 122b, respectively. The upper unit 130 is a pinch that presses the conveying roller 121a and the width adjusting roller 122a, respectively. Rollers 131 and 132 are provided.

  These rollers can be moved up and down with respect to the conveying paths 101 and 102 facing each other. Further, the conveying rollers 121a and 121b are driven by using the common conveying motor 105 as a power source, and the width adjusting rollers 122a and 122b are driven by the common width adjusting motor 104. Among these, for the width adjusting rollers 122a and 122b, the power from the width adjusting motor 104 is switched and transmitted by a drive shaft 123 having a rotation axis parallel to the width direction of each of the conveying paths 101 and 102.

  Further, the lower unit 110 and the upper unit 130 are provided with sheet stoppers 113 and 133 that project in the conveyance paths 102 and 101 and restrict the conveyance of the medium. The sheet stoppers 113 and 133 are provided so as to be openable and closable with respect to the conveyance paths 102 and 101, respectively.

  Hereinafter, the width alignment and transport operation in each unit will be briefly described. In the following description, a state where each roller protrudes in the conveyance paths 101 and 102 and contacts the medium is expressed as a “closed state”, and a state where the rollers are retracted from the conveyance paths 101 and 102 is expressed as an “open state”. Similarly, for the sheet stoppers 113 and 133, the protruding state and the retracted state with respect to the conveyance paths 101 and 102 are expressed as “open state” and “closed state”, respectively.

  First, when a slip is inserted into the conveyance path 101, in an initial state, the sheet stopper 133 is in a closed state. In this state, the slip is inserted into the conveyance path 101 by the operator, and the leading end of the slip is placed on the sheet stopper 133. Abutted. Thereby, the alignment of the conveyance direction in the width-shifting operation of the slip is performed.

  Next, the width adjusting roller 122a and the pinch roller 132 are closed, and the width adjusting roller 122a is driven to perform the width adjusting operation of the slip. After completion of the width aligning operation, the conveying roller 121a and the pinch roller 131 are closed, the width aligning roller 122a and the pinch roller 132 are opened, and the sheet stopper 133 is opened, and the conveying roller The slip is sent to the subsequent skew detection unit 100b by driving 121a.

  After that, if the skew amount of the slip exceeds the allowable value, the slip is reversely fed and stopped at the position where the width aligning operation is re-executed, and then the width aligning roller 122a and the pinch roller 132 are closed. The conveying roller 121a and the pinch roller 131 are opened. The position of the slip at the time of re-execution is set to the inside of the apparatus from the time of initial insertion, so that the position where the width adjusting roller 122a and the pinch roller 131 are in contact with the slip is set to the side in which the slip is discharged from the time of initial insertion. It is corrected to become.

  After the width aligning operation is re-executed by driving the width aligning roller 122a, the conveying roller 121a and the pinch roller 131 are closed again, the width aligning roller 122a and the pinch roller 132 are opened again, and the slip is To the skew detection unit 100b.

  By the way, in the upper unit 130, the sheet stopper 133 is closed and the pinch roller 131 is opened during the width-shifting operation when the slip is initially inserted. Further, the open / closed state of each part is reversed during the subsequent inward conveyance. Therefore, the sheet stopper 133 and the pinch roller 131 only have to be raised and lowered alternately, and the conventional upper unit 130 has a simple mechanism for this purpose. However, according to the present invention, since the slip is disposed on the inner side of the apparatus at the subsequent re-execution of the width aligning operation, it is necessary to open both the sheet stopper 133 and the pinch roller 131.

  In the present embodiment, in order to enable such an operation, the number of parts is increased by using a drive switching mechanism for the width-adjusting rollers 122a and 122b of the drive shaft 123 provided in the intermediate unit 120. And increase installation space to a minimum.

  The operation at the time of inserting a passbook for the conveyance path 102 is basically the same as that at the time of inserting a slip. However, in the case of a bankbook, the re-execution position of the width alignment operation is performed at the same position as the width alignment execution position at the time of initial insertion. Accordingly, the lower unit 110 may be provided with a mechanism that simply raises and lowers the sheet stopper 113 and the pinch roller 111 alternately.

  Next, a structure for transmitting power to the width adjusting rollers 122a and 122b by the drive shaft 123 will be described in detail with reference to FIG. FIG. 4 is a perspective view showing the internal structure of the intermediate unit 120.

  FIG. 4 shows the intermediate unit 120 when the slip insertion direction is the direction of the arrow A. That is, the lower surface of the bottom plate 120 a of the intermediate unit 120 is the upper surface of the passbook transport path 102. In addition, an upper surface plate is provided on the upper surface of the intermediate unit 120, the upper surface of which is the lower surface of the slip conveyance path 101, which is omitted in the drawing.

  In the intermediate unit 120, as shown in the drawing, a drive shaft 123 is rotatably provided so as to penetrate the side plates 120b and 120c. One end 123a of the drive shaft 123 protrudes from the side plate 120b. Further, a spur gear 124 is fixed on the same rotating shaft at the other end, and the power from the width adjusting motor 104 is transmitted to the spur gear 124 and the drive shaft 123 is rotated. Further, the drive shaft 123 on the side plate 120c side is provided with a shaft moving mechanism 125 that moves the drive shaft 123 in a direction parallel to the rotation axis (B direction in the figure) using the solenoid 125a as a drive source.

  Inside the intermediate unit 120, bevel gears 126 a and 126 b are provided on the drive shaft 123 so as to face each other. Also, bevel gears 127a and 127b that mesh with the bevel gears 126a and 126b, respectively, are provided, and these bevel gears 127a and 127b respectively provide the rotational force of the drive shaft 123 to the width adjusting rollers 122a and 122b. introduce.

  Here, when the drive shaft 123 is moved to the side plate 120b side by the operation of the shaft moving mechanism 125, the bevel gear 126a and the bevel gear 127a are engaged, and when the drive shaft 123 is moved to the side plate 120c side, the bevel gear 126b. The bevel gear 127b meshes. Accordingly, when the drive shaft 123 is positioned on the side plate 120b side, the slip width-shifting operation is performed, and when the drive shaft 123 is positioned on the side plate 120c side, the passbook width-shifting operation is performed. Moreover, when the slip width-shifting operation is performed, the protruding amount of the drive shaft 123 from the side plate 120b increases.

  The width-adjusting rollers 122a and 122b are lifted and lowered so as to protrude into the transport paths 101 and 102 when a driving force is transmitted to each of them, but a lifting mechanism for this purpose is omitted in the drawing. In addition to this, the intermediate unit 120 is provided with conveying rollers 121a and 121b and their driving mechanisms, which are also omitted in the drawing.

Next, FIG. 5 is a perspective view showing the internal structure of the upper unit 130.
FIG. 5 shows the upper unit 130 when the insertion direction of the slip is an arrow C. That is, the lower surface of the upper unit 130 in the drawing corresponds to the upper surface of the slip conveyance path 101. In FIG. 5, a part of the upper unit 130 is shown broken away so that the internal structure appears.

  As shown in FIG. 5, the upper unit 130 is provided with an elevating shaft 134 for elevating the pinch roller 131 and an opening / closing shaft 135 for opening and closing the sheet stopper 133, respectively. The pinch roller 131 is fixed to the elevating shaft 134 via the elevating arm 131a, and moves up and down as the elevating shaft 134 rotates, so that the open state and the closed state with respect to the conveyance path 101 are switched. The sheet stopper 133 is fixed to the opening / closing shaft 135 and moves up and down as the opening / closing shaft 135 rotates, so that an open state and a closed state with respect to the conveyance path 101 are switched.

  Further, a drive mechanism 136 for rotationally driving the elevating shaft 134 and the opening / closing shaft 135 is provided outside the side plate 130a. The direction in which the drive mechanism 136 is provided coincides with the direction of the side plate 120b in the intermediate unit 120. The drive mechanism 136 includes a solenoid 136a as a power source. On the other hand, the levers 136b and 136c are fixed to the end of the elevating shaft 134, and when the solenoid 136a is brought into a suction state and the lever 136b rotates, the pinch roller 131 is lowered to a closed state. A lever 136d is fixed to the end of the opening / closing shaft 135. When the lever 136c is rotated by suction of the solenoid 136a, the lever 136c presses the lever 136d, and the opening / closing shaft 135 is rotated in the opposite direction to the lever 136c. Then, the sheet stopper 133 rises to be in an open state.

  Further, a lever 136e is rotatably attached to the opening / closing shaft 135. As will be described later, the lever 136e is disposed so as to be in contact with the end portion 123a of the drive shaft 123 of the intermediate unit 120 and to restrict rotation. The structure of the drive mechanism 136 will be described in detail later with reference to FIG.

Next, FIG. 6 is a perspective view showing the lower surface of the upper unit 130.
FIG. 6 shows the lower surface of the upper unit 130 when the slip insertion direction is the direction of the arrow D. The bottom surface portion 130 b constituting the lower surface is the upper surface of the slip conveyance path 101. Through holes 130c and 130d for lowering the pinch roller 131 and the sheet stopper 133 to the conveyance path 101 are provided in the bottom surface portion 130b. In a closed state, the pinch roller 131 and the sheet stopper 133 pass through the through holes 130c and 130d and project into the conveyance path 101, respectively. Furthermore, a through hole 130e for exposing the pinch roller 132 to the transport path 101 is also provided in the bottom surface portion 130b.

  Next, the structure and operation of the drive mechanism 136 that rotationally drives the elevating shaft 134 and the opening / closing shaft 135 will be described. FIG. 7 is a side view showing the structure of the drive mechanism 136.

  FIG. 7 shows the drive mechanism 136 as viewed from the side plate 130 a side of the upper unit 130. Therefore, the slip conveyance path 101 is disposed on the lower surface of the upper unit 130. Further, it is assumed that the slip is inserted in the direction of the arrow E with respect to the conveyance path 101.

  As shown in this figure, levers 136b and 136c are fixed to the elevating shaft 134. The lever 136b is connected to the movable portion 136f of the solenoid 136a, and is rotated in accordance with the operation of the solenoid 136a together with the lever 136c. Further, the lever 136b is urged in the clockwise direction in the drawing with respect to the rotation axis of the elevating shaft 134 by a spring 136g.

  On the other hand, a lever 136 d is fixed to the opening / closing shaft 135. The lever 136d is urged counterclockwise in the drawing with respect to the rotation axis of the opening / closing shaft 135 by a spring 136h. Further, when the tip of the lever 136c comes into contact, the lever 136d is pressed and rotated.

  Further, a lever 136e is rotatably provided on the opening / closing shaft 135. A spring 136i is provided between the lever 136e and the lever 136d, and the lever 136e is biased in the clockwise direction of the open / close shaft 135 in the drawing with respect to the lever 136d. At the same time, the lever 136e is restricted from rotating more than a predetermined angle with respect to the lever 136d only in the clockwise direction in the figure.

  This figure also shows the positional relationship of the drive shaft 123 when the upper unit 130 is installed above the intermediate unit 120. The drive shaft 123 abuts against the tip of the lever 136e and restricts its rotation in a state where it is positioned in the forward direction in the drawing (ie, in a state of performing a shifting operation on the slip).

  Here, FIGS. 8, 9 and 10 simultaneously show the positional relationship between the drive mechanism 136, the pinch roller 131 and the sheet stopper 133 inside the upper unit 130, and using these FIGS. The operation in the upper unit 130 will be described. 8 to 10 also show the position of the drive shaft 123 of the intermediate unit 120 at the same time as in FIG.

FIG. 8 is a diagram showing an operation state of the upper unit 130 during the slip-shifting operation of the slip at the initial insertion.
FIG. 8 shows a state of each part when the slip is first inserted and the width adjusting operation is performed. In this state, the suction of the solenoid 136a is released. That is, when the lever 136b is urged by the spring 136g, the pinch roller 131 is opened. Further, the lever 136d is biased by the spring 136h, so that the sheet stopper 133 is closed. Therefore, after the leading end portion of the inserted slip comes into contact with the sheet stopper 133, the drive shaft 123 moves to the front side in the figure, and the width adjusting roller 122a (not shown) is closed, so that the width of the slip is reduced. Is called.

  In this state, the tip end of the lever 136e abuts on the drive shaft 123 protruding toward the front side in the figure, and thereby the rotation of the lever 136e in the clockwise direction with respect to the opening / closing shaft 135 is restricted.

Next, FIG. 9 is a diagram showing an operation state of the upper unit 130 during the conveyance of the slip after the end of the width adjusting operation.
When the shifting operation at the time of initial insertion is completed, as shown in FIG. 9, the solenoid 136a is brought into a suction state, the lever 136b is pulled in the direction of arrow F in the drawing, and the lifting shaft 134 is rotated in the direction of arrow G in the drawing. Thus, the conveying pinch roller 131 is in a closed state. The lever 136c is also rotated at the same time, and the tip of the lever 136c presses the lever 136d. As a result, the opening / closing shaft 135 is rotated in the direction of the arrow H in the figure, and the sheet stopper 133 is opened. In this state, the drive shaft 123 is moved to the width-shifting operation position with respect to the bankbook (that is, in the forward direction in the figure), and the width-shifting roller 122a (not shown) is opened, so that the slip detection unit 100b in the slip is inside. It is conveyed to.

  Since the lever 136e is in contact with the drive shaft 123 until the drive shaft 123 is moved in the forward direction in the figure, the lever 136e does not rotate in conjunction with the opening / closing shaft 135. Then, after the drive shaft 123 is moved, the lever 136e is urged by the spring 136i and rotated in the clockwise direction of the open / close shaft 135 (in the arrow H direction), and is stopped at a position that maintains a predetermined angle with the lever 136d. This state is the state shown in FIG.

Next, FIG. 10 is a diagram illustrating an operation state of the upper unit 130 when the width-shifting operation is re-executed after the skew detection.
If the width adjusting operation is re-executed according to the skew detection result, the slip is conveyed to the re-execution position with the state shown in FIG. This re-execution position is set to the inside of the apparatus from the time of the width adjusting operation at the time of initial insertion.

  When the slip is conveyed to the re-execution position, the drive shaft 123 is again moved to the front side in the drawing, and the width adjusting roller 122a (not shown) is closed. Then, the suction of the solenoid 136a is released. As a result, as shown in FIG. 10, the lever 136b is urged by the spring 136g, the lifting shaft 134 is rotated in the direction of arrow I in the figure, and the conveying pinch roller 131 is opened.

  However, at this time, the tip of the lever 136e comes into contact with the drive shaft 123, and the rotation of the lever 136e in the counterclockwise direction in the drawing around the opening / closing shaft 135 is restricted. Here, since the lever 136d is biased by the spring 136i and maintains a constant angle with respect to the lever 136e, the opening / closing shaft 135 does not rotate, and the sheet stopper 133 together with the pinch roller 131 remains open. As a result, it is possible to carry out the slip shifting operation on the inside of the apparatus from the initial insertion.

  As described above, in this embodiment, the lever 136e is added to the conventional mechanism, and the lever 136e is added to the drive shaft 123 by utilizing the movement of the drive shaft 123 accompanying the drive switching of the width-adjusting rollers 122a and 122b. By bringing the leading ends into contact with each other, both the pinch roller 131 and the sheet stopper 133 can be opened. Therefore, such a state can be realized by adding the minimum necessary components, and an increase in cost can be suppressed, and an increase in the installation space of the apparatus can be prevented.

Lastly, the control of the shifting operation in this embodiment will be described in detail.
FIG. 11 is a diagram showing the arrangement of various sensors in the slip conveyance path 101.
FIG. 11 shows the conveyance path 101 when viewed from the top surface of the form processing apparatus 100. That is, the conveyance path surface 101a in the drawing is provided on the upper surface of the intermediate unit 120. The slip is inserted in the direction of arrow J in the figure.

  As shown in FIG. 11, a transport roller 121a is disposed along the transport direction on the transport path surface 101a. A width-adjusting roller 122a is disposed in the preceding stage corresponding to the width-aligning mechanism portion 100a, and a lowered position 133b of the sheet stopper 133 exists in the subsequent stage.

  Abutting sensors 141a and 141b, width-adjustable sensors 142a and 142b, and skew detection sensors 143a and 143b for detecting the presence or absence of a slip are provided on the conveyance path surface 101a. Each sensor is an optical sensor including a light emitting unit and a light receiving unit that face the conveyance path 101. In the following description, the state where the light from the light emitting unit is blocked by the slip and the presence of the slip is detected is expressed as the “ON state” of the sensor.

  The width of the slip is adjusted with respect to the abutting member 101b on the left side (downward direction in the figure) of the conveyance road surface 101a. The abutting sensors 141a and 141b are provided at the end of the conveying path surface 101a on the abutting member 101b side, and detect whether the slip is abutted against the abutting member 101b. The width-adjustable sensors 142a and 142b are respectively provided at a predetermined distance in the width direction from the abutting member 101b and at a position immediately before the lowered position 133b of the sheet stopper 133, and the inserted slip is at the position where the width-shifting operation is performed. Detect whether or not there is.

  The skew detection sensors 143a and 143b are provided in parallel with the width direction of the transport path 101 and detect the skew amount of the transported slip. Specifically, the skew amount at the leading edge of the slip can be detected by detecting the time difference when each sensor is turned on as the slip is conveyed.

  The output signals of these sensors are input to a control unit (not shown) that executes the slip-shifting operation and skew detection operation. Based on these input signals, the control unit controls the driving of the conveying motor 105 and the width adjusting motor 104, the driving of the raising and lowering mechanisms of the rollers and the sheet stopper 133, the driving switching mechanism of the rollers, and the solenoids 125a and 136a. To do.

FIG. 12 is a flowchart showing the flow of control for the width-shifting operation and skew detection operation for a slip.
At the start of the flowchart of FIG. 12, the conveying roller 121a is in the open state, the sheet stopper 133 is in the closed state, and the power transmission by the drive shaft 123 is switched to the passbook conveying side, and the width adjusting roller 122a is also open. It is in a state. At this time, each part of the upper unit 130 is in the state shown in FIG.

  In step S1201, the operator inserts a slip into the conveyance path 101 and the width-adjustable sensors 142a and 142b are turned on, whereby insertion of the slip is detected and the leading end of the slip comes into contact with the sheet stopper 133. Thus, it is detected that the slip has been arranged at the position where the width can be adjusted.

  In step S1202, the detection states of the butting sensors 141a and 141b are determined. If both sensors are in the ON state, it is determined that the slip has been properly aligned with the butting member 101b, and the process proceeds to step S1203.

  In step S1203, the conveyance roller 121a is closed and the sheet stopper 133 is opened. At this time, in the upper unit 130, the solenoid 136a is brought into a suction state, and the conveying pinch roller 131 is also brought into a closed state (corresponding to the state shown in FIG. 9).

  On the other hand, if one of the butting sensors 141a and 141b is OFF in step S1202, the process proceeds to step S1204. In step S1204, the width adjusting operation of the slip is performed using the width adjusting roller 122a. Note that the processing in step S1204 will be described in detail with reference to FIG. After this width adjustment operation is completed, the process proceeds to step S1205. The state of each roller and the sheet stopper 133 at this time is the same as at the end of step S1203.

  In step S1205, the conveyance roller 121a is rotated to convey the slip to the inside. In step S1206, the skew amount of the conveyed slip is determined based on the detection signals of the skew detection sensors 143a and 143b. If the skew amount is less than or equal to the allowable value, it is determined that the width has been properly adjusted, and the process proceeds to step S1207, where the slip is further conveyed to the inside and a predetermined process is performed.

  If it is determined in step S1206 that the skew feeding amount exceeds the allowable value and is less than or equal to the re-executable amount, the process proceeds to step S1208 to perform re-execution processing for the width adjusting operation. The processing in step S1208 will be described in detail with reference to FIG.

  Furthermore, if the skew amount exceeds the re-executable amount in step S1206, the skew amount is too large and cannot be properly aligned, so the process proceeds to step S1209, and the conveyance roller 121a is rotated in the reverse direction to generate the slip. Discharge.

FIG. 13 is a flowchart showing the flow of the width adjusting operation process.
In step S1301, the width adjusting roller 122a is closed. At this time, the drive shaft 123 is slid to a position for driving the width adjusting roller 122a. In step S1302, the width adjusting roller 122a is rotated. At this time, the width adjusting motor 104, which is a stepping motor, is rotated by a predetermined number of steps.

  In step S1303, the detection states of the butting sensors 141a and 141b at this time are determined, and if one of them is OFF, the process proceeds to step S1304. If both sensors are in the ON state, the process proceeds to step S1305.

  The process in step S1304 is a process for correcting the posture and the twist of the slip and performing the correct width alignment when the slip moving distance during the width shifting operation is large. In step S1304, a process for rotating the width adjusting roller 122a in the forward direction and the reverse direction is performed in accordance with the number of rotation steps of the butting sensors 141a and 141b and the width adjusting motor 104. Here, when both sensors are in the OFF state, the width adjusting roller 122a is further rotated in the forward direction. When one of the sensors is turned on, the width adjusting roller 122a is rotated in the reverse direction to separate the slip from the abutting member 101b, and then the width adjusting roller 122a is rotated in the forward direction again. Do a close-up. Thereafter, if both of the butting sensors 141a and 141b are in the ON state, the process proceeds to step S1305. If one of the butting sensors 141a and 141b is in the OFF state, it is determined that correct width adjustment is impossible and the slip is discharged.

  In step S1305, the conveying roller 121a is closed and the sheet stopper 133 is opened. At this time, in the upper unit 130, the solenoid 136a is brought into a suction state, and the conveying pinch roller 131 is also brought into a closed state. In step S1306, the width adjusting roller 122a is opened. At this time, the drive shaft 123 is switched to drive on the bankbook side, and each part of the upper unit 130 is in the state shown in FIG. Thereafter, the process returns to step S1205 in FIG. 12, and the slip is conveyed to the inside.

Next, FIG. 14 is a flowchart showing the flow of the width adjusting operation re-execution process.
In step S1401, the conveyance roller 121a is rotated in the reverse direction, and the slip is discharged to the re-execution position of the width adjusting operation. As described above, the re-execution position is set to the inside of the apparatus with respect to the position adjustment operation position when the slip is initially inserted. Accordingly, the slip is arranged so as to cover the lowered position 133b of the sheet stopper 133.

In step S1402, the width adjusting roller 122a is closed. At this time, the drive shaft 123 is slid to the slip drive side.
In step S1403, the width adjusting motor 104 is rotated by a predetermined step, the width adjusting roller 122a is rotated, and the slip is adjusted to the abutting member 101b side. At this time, the contact position of the width adjusting roller 122a with respect to the slip is corrected to the discharge direction side as compared with the initial insertion, so that more accurate width adjustment is possible.

  In step S1404, the detection states of the butting sensors 141a and 141b at this time are determined, and if one of them is OFF, the process proceeds to step S1405. In step S1405, processing similar to that in step S1304 in FIG. 13 is performed. If both sensors are ON in step S1404, the process proceeds to step S1406.

  In step S1406, the width adjusting roller 122a is rotated in the reverse direction. At this time, the slip is separated from the abutting member 101b until one of the abutting sensors 141a and 141b is turned off. In step S1407, the width adjustment roller 122a is rotated in the forward direction again, and the width adjustment is performed until both the butting sensors 141a and 141b are turned on.

  In step S1408, the number of repetitions is counted to determine whether or not the predetermined number N has been reached. If not, the process returns to step S1406. As a result, the slip separating operation in step S1406 and the slip shifting operation in step S1407 are repeated a predetermined number of times. With such an operation, the slip is vibrated in the width direction, the sliding frictional force with the conveyance road surface 101a is reduced, and the slip in the width direction of the slip is smooth. Therefore, for example, the case where the slip is excessively pressed against the abutting member 101b is eliminated, and the posture of the slip is corrected.

  In step S1409, the conveying roller 121a is closed and the sheet stopper 133 is opened. At this time, in the upper unit 130, the solenoid 136a is brought into a suction state, and the conveying pinch roller 131 is also brought into a closed state. In step S1410, the width adjusting roller 122a is opened. At this time, the drive shaft 123 is switched to drive on the bankbook side, and each part of the upper unit 130 is in the state shown in FIG. Thereafter, the process returns to step S1205 in FIG. 12, and the slip is conveyed again inside.

  In the above-described embodiment of the present invention, the re-execution position is set to the inside of the apparatus from the width-shifting operation position at the time of initial insertion of the slip, so that the inserted slip regardless of the difference in length in the transport direction. Therefore, it is possible to prevent the slip from being mistaken and to read and print the slip accurately. Further, the change in the raising / lowering mechanism of each roller and the sheet stopper 133 accompanying such a change in the re-execution position is minimized by using the slide mechanism of the drive shaft 123 for switching the driving of the width-adjusting rollers 122a and 122b. It is limited to the limit. Therefore, it is possible to improve processing stability without increasing manufacturing cost and installation space for a form processing apparatus that processes both slips and passbooks.
