Description

  The present invention relates to a printing device of an ATM device (automatic deposit payment machine) and a cleaning device of an automatic transaction device that reads a mark sheet.

  In an ATM device, ink or the like from a printing device that records a transaction adheres to a roller that conveys a passbook, and this causes the passbook to become soiled, so it is necessary to clean the passbook rollers or sensors appropriately. . Even in a mark sheet reading device that does not have a printing device, dust or worn paper or the like is contaminated with internal rollers or sensors, so cleaning is necessary.

  Therefore, in order to clean the internal roller without removing the lid or the like of the apparatus, a method of cleaning the internal roller by inserting a dedicated cleaning sheet into the apparatus instead of a normal medium is widely performed. .

  Then, assuming that the cleaning of the roller is not sufficient by simply passing the cleaning sheet through the inside, both ends of the cleaning sheet are sandwiched by two sets of rollers, and the cleaning sheet is sandwiched and fixed by one roller so as not to move. A method has also been proposed in which a roller is idled on a cleaning sheet so that the roller is more reliably cleaned (Patent Document 1).

The passbook insertion / extraction unit 15 is a part that can accept a passbook and record transaction contents.

  FIG. 2 is a diagram of the ATM device 1 as viewed from the right side of FIG. 1, and is a diagram showing an outline of the arrangement inside the ATM device 1 of the printing device 20 that performs printing on a passbook. A printing device 20 is provided inside the bankbook insertion / extraction unit 15.

  FIG. 3 is a diagram illustrating an outline of the internal configuration of the printing apparatus 20. The printing apparatus 20 mainly includes a front-stage unit 22, a print-bending unit 24, a rear-stage unit 26, a retracting unit 28, a control unit 30, a front-stage issue unit 32, and a rear-stage issue unit 34. The front stage 22 is a place where the passbook inserted into the passbook insertion / extraction unit 15 by the user is first transported. The front part 22 is provided with an MS part 36 for reading / writing a magnetic part attached to the front or back surface of the bankbook. The MS unit 36 includes a magnetic head, a drive unit that causes the magnetic head to travel along the passbook, a signal recording / reproducing unit for the magnetic head, and the like.

  The printing pager 24 is a part that prints predetermined information on the passbook conveyed from the front part 22. The print turning part 24 includes an optical lead part 38, a printing part 40, and a page turning part 42. The optical lead unit 38 identifies whether the current page of the passbook is printed, and optically reads the page mark. The printing unit 40 includes printing means such as a print head method, and prints characters, symbols, numbers, and the like at predetermined positions in the passbook. The page turning section 42 turns a page to be printed from a passbook.

The rear stage part 26 has a top and bottom turn part 46. The top and bottom turn unit 46 rotates the bankbook horizontally to reverse the direction of the bankbook.
The retracting unit 28 is provided below the rear stage unit 26. The evacuation unit 28 is a place for temporarily evacuating the passbook printed to the last page. This is a place for saving the previous passbook in order to perform the process of issuing a new passbook.

  The first issuer 32 and the second issuer 34 are locations for storing new passbooks issued in place of expired passbooks (passbooks printed up to the last page). The preceding issuer 32 has cassettes 1 and 2 for storing new passbooks. The post-issuance unit 34 has cassettes 3 and 4 for storing new passbooks. The reason why the cassettes are divided is that the bankbooks are issued separately by type (normal, regular, general, etc.). It is also possible to store the same type of passbook in a plurality of cassettes.

  The taking-in part 44 is provided at a position farther behind the retracting part 28. The capturing unit 44 is a place for storing a passbook that the user has forgotten to take. The passbook that has undergone processing such as printing is transported in the order of the rear stage portion 26 → the print turning portion 24 → the front stage portion 22, returned to the passbook insertion / extraction unit 15, and discharged. However, there is a case where the discharged passbook is forgotten by the user, and at that time, it is stored in the inside to prevent theft. If it is not taken out from the user even after a certain period of time has elapsed after being ejected, the passbook is transported inside again and stored in the take-in unit 44. In the following, with respect to the banknote transport direction, the rightward transport is referred to as the suction direction and the leftward transport is referred to as the discharge direction.

  The control unit 30 controls various operations of the entire printing apparatus 20. The control unit 30 includes a CPU, a program for operating the CPU, other ICs, a necessary memory, and the like. The control unit 30 controls the operations of the MS unit 36, the optical lead unit 38, the printing unit 40, the page turning unit 42, the capture unit 44, the top and bottom turn unit 46, etc., along with the conveyance of the bankbook. In addition, when the cleaning mode is set instead of the normal passbook printing, the control unit 30 executes a cleaning process, which will be described in detail below, in accordance with a program in which the cleaning process is recorded, so that a part of the printing apparatus is It functions as a cleaning device.

  FIG. 4 is a block diagram showing motors and sensors mainly controlled by the control unit 30 in the cleaning mode. The printing apparatus 20 includes a first motor 61, a second motor 62, a third motor 63, a fourth motor 64, and a fifth motor 65 as drive sources for conveying the bankbook, and the control unit 30 includes a motor driver. And control these motors. All motors are step motors. The MS unit 36 reads information from the magnetic stripe portion of the passbook, performs printing using the read information, and writes the printed passbook information to the magnetic stripe portion again.

  The printing apparatus 20 includes a first sensor 71, a second sensor 72, a third sensor 73, a fourth sensor 74, a fifth sensor 75, a sixth sensor 76, and a seventh sensor 77 as position sensors that detect the conveyance position of the bankbook. The control unit 30 controls the rotation of the motor according to the output from these sensors. Each sensor is a regressive reflection type sensor that detects the passbook from both sides.

  In addition, the printing apparatus 20 includes a solenoid 80. The solenoid 80 opens and closes the gate of the retracting unit 28. Based on the position detection of the first sensor 71 to the seventh sensor 77, the control unit 30 drives each motor and solenoid to carry the bankbook.

  FIG. 5 is a diagram illustrating the shape of a cleaning medium (also referred to as a cleaning card) used for cleaning the printing apparatus 20. The top is a front view and the bottom is a side view. In this figure, the cleaning medium 90 is shown in a direction in which the left-right direction is the transport direction. That is, the cleaning medium 90 is inserted into the passbook insertion / extraction unit 15 from the right end of the figure. The cleaning medium 90 is based on a nonwoven fabric material 92 having a thickness of about 1 mm to 2 mm, and a brush 94 having a short hair tip is planted in part. In addition, the width dimension (direction orthogonal to the insertion direction) of the cleaning medium 90 is the same length as the passbook.

  Four brushes 94 are planted on both surfaces of the cleaning medium 90. The height of the bristles of the brush 94 is about 1 to 2 mm. The brush 94 is for cleaning the surface of the optical sensor (the first sensor 71 to the seventh sensor 77), and the sensor is dry-cleaned by the brush. Here, since the optical sensor to be cleaned is a retroreflective sensor that detects a passbook, the brush is provided on both surfaces of the cleaning medium 90. If the sensor is arranged only on one side of the bankbook, the brush may be only on one side.

  Further, the brush 94 is slightly shifted in planting position between the front surface and the back surface except for the rightmost side (see the side view). This is because if the front and back sides are in the same position, the brush is elastically deformed at the same time as it passes through the sensor, making it difficult for the elastic deformation. In the present embodiment, the brush 94 on the right side of the cleaning medium 90 in the drawing is small in amount and divided into left and right, and is not easily deformed. Also good.

  Further, the cleaning medium 90 is provided with holes 96 and 97 at positions slightly from the right from the center. The holes 96 and 97 are openings for avoiding rollers that are not to be cleaned, and will be described in detail later. The holes 96 and 97 are provided in two locations along the width direction (the vertical direction in the figure). This is because two rollers to be avoided are provided in parallel in the width direction.

  On the cleaning medium 90, lines of cleaning areas 98a, 98b, 98c, and 98d indicated by two-dot chain lines are printed as an instruction range for applying the cleaning chemical. Since ink or the like is attached to the roller, it is necessary to clean the roller with a special chemical. Therefore, it is necessary to make the cleaning medium 90 soaked with the cleaning agent before inserting the cleaning medium 90. However, since the range is clearly indicated, the operation is facilitated and the use of unnecessary chemicals is prevented. Is done. These cleaning areas 98a to 98d correspond to the positions of the rollers to be cleaned.

Although not shown, the range of the magnetic head cleaning area is also displayed on the back surface.
Further, a notch 99 for preventing reverse insertion is provided in the upper left corner of the cleaning medium 90. The presence or absence of the notch 99 is detected by an optical sensor close to the passbook insertion / extraction unit 15 to detect erroneous insertion. In the following description, the right end of the cleaning medium 90 is also referred to as the front end and the left end is also referred to as the rear end based on the conveyance direction.

  6 to 18 are diagrams for specifically explaining the cleaning process in the cleaning mode. First, FIGS. 6 to 9 are diagrams showing the position of the cleaning medium 90 conveyed inside the printing apparatus 20 corresponding to each state. FIG. 4 schematically shows the position of the cleaning medium conveyed with respect to each roller and sensor in each state in the printing apparatus 20 viewed from the side surface shown in FIG. 3.

  The chart of A) in FIG. 6 is an overall chart collectively showing the arrangement positions of the respective rollers and sensors between the front stage portion 22 and the retracting portion 28. Each roller is composed of a pair of rollers that convey the passbook with a constant pressure.

  The left end of the chart is a passbook insertion / extraction unit 15. A first roller 101, a second roller 102, and a third roller 103 are provided in the front stage 22 in order from the passbook insertion / extraction unit 15. The first roller 101, the second roller 102, and the third roller 103 are driven by the first motor 61. In the front stage 22, as a sensor for detecting the conveyance position of the bankbook (cleaning medium 90), the first sensor 71 is closer to the take-out part than the first roller 101, and the second roller 102 is closer to the take-out part. A seventh sensor 77 is provided.

  The print curling unit 24 includes a fourth roller 104, a fifth roller 105, a sixth roller 106, a seventh roller 107, an eighth roller 108, and a curling roller 111. The fourth roller 104, the fifth roller 105, the sixth roller 106, and the eighth roller 108 are driven by the second motor 62. The printing unit 40 is disposed between the fourth roller 104 and the fifth roller 105. The seventh roller 107 and the turning roller 111 are provided coaxially and are driven by the third motor 63. Only the turning roller 111 is a fan-shaped roller only on one side. The fourth motor 64 is a motor that adjusts the height of the conveyance path in the vicinity of the seventh roller 107 when the bankbook is used. When the bankbook is to be rolled, the height of the conveyance path is lowered in the vicinity of the seventh roller 107 by the fourth motor 64 so that the bankbook contacts the rolling roller 111.

  A second sensor 72, a third sensor 73, and a fourth sensor 74 are provided as sensors for detecting the transport position of the bankbook (cleaning medium 90). The second sensor 72 is provided immediately after the fourth roller 104, the third sensor 73 is provided immediately after the fifth roller 105, and the fourth sensor 74 is provided immediately after the seventh roller 107.

In the rear stage portion 26, a ninth roller 109 and a fifth sensor 75 are provided further inside than the ninth roller 109. The ninth roller 109 is driven by the fifth motor 65.
The retraction unit 28 is provided with a tenth roller 110 and a sixth sensor 76 immediately before the tenth roller 110. The tenth roller 110 is driven by the fifth motor 65 in the same manner as the ninth roller 109. Further, the retracting portion 28 is provided with a gate (not shown) and is opened and closed by a solenoid 80.

  Further, the arrangement of the rollers as seen from the top is as shown in FIGS. 10 and 11 are views of the relationship between the rollers and the cleaning medium 90 conveyed from above, and will be described in detail later. Each roller is a molded product of cylindrical rubber or resin, and the shaft passes through the center. Each roller is composed of a pair of upper and lower sides so as to sandwich the passbook, one of which is the main driving side and the other is the driven side. In addition, each roller is divided into two at a predetermined distance in the width direction of the bankbook (FIG. 10). The driving force is transmitted from the driving motor to each roller by a gear or a belt, but the transmission portion is not shown.

12 to 18 are flowcharts showing the procedure of the cleaning process for each state (stage).
The procedure of the cleaning process will be described with reference to FIGS. Here, the entire cleaning process will be described in order from state 1 to state 8 for each roller to be cleaned. The cleaning process is mainly executed by the control unit 30 according to the program. Here, the cleaning process is executed by setting the printing apparatus in a cleaning mode in advance.

FIG. 12 is a flowchart showing the procedure of the cleaning process in the state 1. State 1 is a process for cleaning the fourth roller 104. The chart of B) in FIG. 6 corresponds.
In step S11, processing for receiving the cleaning medium 90 is performed. When the cleaning medium 90 is inserted into the passbook insertion / extraction unit 15 by the operator, the cleaning medium 90 blocks light received by the first sensor 71. As a result, the first sensor 71 detects that the cleaning medium has been inserted. The control unit 30 determines that the cleaning medium 90 has been inserted based on detection by the first sensor 71. When the cleaning medium 90 is inserted backwards and forwards, the cleaning medium 90 has a notch 99 at one end, so that only one sensor can detect the medium, so that it is determined that the medium is erroneously inserted and the roller is not driven.

In step S <b> 12, the control unit 30 rotates the first motor 61 and the second motor 62 in the suction direction.
In step S13, the cleaning medium 90 is conveyed. Here, after the cleaning medium 90 is detected by the second sensor 72, the first motor 61 and the second motor 62 are further rotated by a predetermined amount (for example, 132 STEP) in the suction direction, and the cleaning medium 90 is conveyed in the suction direction. . After the conveyance, the first motor 61 and the second motor 62 are stopped.

  The chart shown in FIG. 6B shows the positions of the first roller 101 to the fourth roller 104 with respect to the cleaning medium 90 conveyed in step S13. Here, B) in FIG. 6 is obtained by extracting the vicinity of the conveyed cleaning medium 90 in the A) overall chart of FIG. Note that the charts shown in FIGS. 7 and 8 to be described below are obtained by extracting a part of the entire chart as in FIG. Here, the first roller 101 to the fourth roller 104 are located on the cleaning medium 90. And the 4th roller 104 is located on the cleaning area | region 98c of the cleaning medium 90 shown in FIG.

  In step S14, the control unit 30 applies a voltage to each phase so that the first motor 61 is excited in the locked state. Here, the locked state means that a voltage is applied to one phase of the motor and the excitation is continued without switching the application of the voltage to the other phase. The rotation state means that the motor is rotated by switching a value for exciting the voltage applied to each phase at a constant interval. The reason why the first motor 61 is locked (self-maintained) by the excitation in the locked state is that the cleaning medium 90 is braked to prevent the cleaning medium 90 from moving. When the first motor 61 is locked, the first roller 101, the second roller 102, and the third roller 103 driven by the first motor 61 are all locked. As a result, the cleaning medium 90 is prevented from moving by the first roller 101, the second roller 102, and the third roller 103.

  In step S15, the second motor 62 is rotated in the suction direction. The second motor 62 is rotated by a predetermined amount (for example, 1000 STEP) in the suction direction, and then the motor 2 is stopped. Due to the rotation of the second motor 62, the fourth roller 104 rotates in the P direction of B) of FIG. Here, since the cleaning medium 90 is locked by the first roller 101 to the third roller 103, the fourth roller 104 moves the cleaning area 98c on the surface of the cleaning medium 90 where the cleaning chemical is applied for a predetermined time. As a result, the fourth roller 104 is cleaned.

  However, during rotation, the control unit 30 monitors the detection of the third sensor 73, as will be described in the next step S16. In step S <b> 16, it is determined whether the third sensor 73 detects the cleaning medium 90 while the second motor 62 is rotating by a predetermined amount or after the second motor 62 is stopped. The third sensor 73 is a sensor located on the suction side with respect to the fifth roller 105, and the locking force to the cleaning medium 90 due to the excitation of the first motor 61 is not sufficient, and the cleaning medium is rotated by the rotation of the fourth roller 104. The case where 90 is conveyed is determined.

  If the third sensor 73 detects that the tip of the cleaning medium 90 has passed in step S16 (YES), the control unit 30 proceeds to step 17 and stops the second motor 62 even during the rotation of the predetermined amount (for example, 1000 STEP). Let Subsequently, in step S18, the excitation of the locked state of the first motor 61 is released, the first motor 61 and the second motor 62 are rotated in the discharge direction, and the cleaning medium 90 present in the third sensor 73 is changed to the first one. The third sensor 73 is moved in the discharge direction until it passes. After the movement, the first motor 61 and the second motor 62 are stopped. End state 1 and proceed to state 2. In this embodiment, if the third sensor 73 detects that the cleaning medium 90 has passed through the tip in step S16 (YES), the cleaning is stopped and the process proceeds to the next step. You may make it return to and clean again.

  On the other hand, if the third sensor 73 does not detect passage of the tip of the cleaning medium 90 in step S16 (NO), it is determined that the movement of the cleaning medium 90 is blocked as scheduled and the cleaning of the fourth roller 104 is completed. End state 1 and proceed to state 2.

FIG. 13 is a flowchart showing the procedure of the cleaning process in the state 2. State 2 is a process for cleaning the fifth roller 105. This corresponds to the chart of C) of FIG.
In step S <b> 21, the control unit 30 rotates the first motor 61 and the second motor 62 in the suction direction. In step S22, after the cleaning medium 90 is detected by the third sensor 73, the first motor 61 and the second motor 62 are rotated by a predetermined amount (for example, 156 STEP) in the suction direction, and further conveyed in the suction direction. After the conveyance, the first motor 61 and the second motor 62 are stopped.

  As shown in FIG. 6C), the second roller 102 to the fifth roller 105 are positioned on the cleaning medium 90. FIG. 10A is a top view of the relationship between the rollers and the cleaning medium 90 being conveyed in the second state. The left end corresponds to the passbook insertion / extraction unit 15, and the left direction is the discharge direction and the right direction is the suction direction, as in FIG. The first roller 101 to the tenth roller 110 are arranged in order from the left end. As shown in this figure, in the state 2, the fourth roller 104 is positioned in the hole 97 of the cleaning medium 90. The fifth roller 105 is located on the cleaning area 98 c of the cleaning medium 90.

  In step S23, as in step S14, the control unit 30 applies the first motor 61 by excitation in the locked state. Thereby, the movement of the cleaning medium 90 is prevented by the second roller 102 and the third roller 103.

  In step S24, the second motor 62 is rotated in the suction direction. The second motor 62 is rotated by a predetermined amount (for example, 1000 STEP) in the suction direction, and then the motor 2 is stopped. The fourth roller 104 and the fifth roller 105 that are driven by the rotation of the second motor 62 rotate in the P direction shown in FIG. Since the cleaning medium 90 is in the locked state, the fifth roller 105 idles the cleaning area 98c on the surface of the cleaning medium 90 by a predetermined number of revolutions, and thereby the fifth roller 105 is cleaned. On the other hand, the fourth roller 104 is located in the hole 97 of the cleaning medium 90 and is not in contact with the cleaning medium 90, and therefore does not contribute to the movement of the cleaning medium 90 even if it rotates. Accordingly, only the fifth roller 105 idles on the cleaning medium 90.

  In state 1, only the fourth roller 104 drives the cleaning medium 90. In the state 2, since the driving force is driven by two rollers, the fourth roller 104 and the fifth roller 105, which share a driving source, when the braking force by the second roller 102 and the third roller 103 is not sufficiently large, The cleaning medium 90 may be conveyed by the total driving force of the fourth roller 104 and the fifth roller 105. Therefore, a part of the plurality of rollers driven by the same motor is prevented from coming into contact with the cleaning medium 90 to reduce the driving force and to ensure that the roller to be cleaned is idling.

  Since the cleaning medium 90 is not driven by the fourth roller 104, the cleaning medium 90 cannot be transported only by driving the fifth roller 105, and the idle rotation occurs. During the rotation, the control unit 30 monitors the detection of the fourth sensor 74. In step S25, it is determined whether the fourth sensor 74 detects the cleaning medium 90 while the second motor 62 is rotating by a predetermined amount or after the second motor 62 is stopped.

  If the fourth sensor 74 detects that the cleaning medium 90 has passed the right end in step S25 (YES), the control unit 30 proceeds to step 26 and stops the rotating second motor 62. Subsequently, in step S27, the excitation of the locked state of the first motor 61 is released, the first motor 61 and the second motor 62 are rotated in the suction direction, and the cleaning medium 90 is moved to the position of the fourth sensor 74. . After the movement, the first motor 61 and the second motor 62 are stopped. End state 2 and proceed to state 3. If the fourth sensor 74 does not detect the cleaning medium 90 in step S25 (NO), it is determined that the cleaning medium 90 is prevented from moving as planned and the cleaning of the fifth roller 105 is completed, and the state 2 And go to state 3.

  FIG. 14 is a flowchart showing the procedure of the cleaning process in the state 3. State 3 is a process for cleaning the sixth roller 106. 7B and FIG. 10B correspond to each other. A) of FIG. 7 is the same overall chart as A) of FIG.

  In step S <b> 31, the control unit 30 rotates the first motor 61 and the second motor 62 in the suction direction. In step S32, the cleaning medium 90 is once conveyed to the back, and the first motor 61 and the second motor 62 are stopped. In step S33, the first motor 61 and the second motor 62 are rotated in the discharge direction. In step S34, the cleaning medium 90 is conveyed in the discharge direction. Here, after the right end of the cleaning medium 90 is detected by the fourth sensor 74, the first motor 61 and the second motor 62 are stopped by rotating the cleaning medium 90 further in a discharging direction by a predetermined amount (for example, 100 STEP). FIG. 10B is a diagram illustrating the positional relationship of each roller with respect to the cleaning medium 90 moved in step S34. As shown in this figure, in the state 3, the fourth roller 104 is positioned in the hole 96 of the cleaning medium 90, and the fifth roller 105 is positioned in the hole 97 of the cleaning medium 90. The sixth roller 106 to be cleaned is located on the cleaning area 98 c of the cleaning medium 90.

  In step S35, the control unit 30 applies the first motor 61 by excitation in the locked state. Thereby, the cleaning medium 90 is prevented from moving by the second roller 102 and the third roller 103.

  In step S36, the second motor 62 is rotated in the suction direction. The second motor 62 is rotated by a predetermined amount (for example, 1000 STEP) in the suction direction, and then the second motor 62 is stopped. Due to the rotation of the second motor 62, the fourth roller 104, the fifth roller 105, and the sixth roller 106 rotate in the direction P of FIG. However, since the fourth roller 104 and the fifth roller 105 are positioned in the hole 96 and the hole 97 of the cleaning medium 90, the cleaning medium 90 is not driven. Since the cleaning medium 90 is rotated only by the sixth roller 106, the lock is maintained. Then, the sixth roller 106 idles the cleaning area 98c on the surface of the cleaning medium 90 for a predetermined time, and the sixth roller 106 is cleaned.

  During the rotation, the control unit 30 monitors the detection of the fourth sensor 74. In step S <b> 37, it is determined whether the fourth sensor 74 detects the cleaning medium 90 while the second motor 62 is rotating by a predetermined amount or after the second motor 62 is stopped.

  If the fourth sensor 74 detects the cleaning medium 90 in step S37 (YES), the control unit 30 proceeds to step 38 and stops the second motor 62. This is when the lock is insufficient. Subsequently, in step S39, the excitation of the locked state of the first motor 61 is released, the first motor 61 and the second motor 62 are rotated in the discharging direction, and the right end of the cleaning medium 90 is in front of the fourth sensor 74. Return until positioned. After the movement, the first motor 61 and the second motor 62 are stopped. End state 3 and proceed to state 4. On the other hand, if the fourth sensor 74 has not detected the cleaning medium 90 in step S37 (NO), it is determined that the cleaning medium 90 has been prevented from moving as scheduled, and the cleaning of the sixth roller 106 has been completed. And go to state 4.

FIG. 15 is a flowchart showing the procedure of the cleaning process in the state 4. State 4 is a process of cleaning the turning roller 111. FIG. 7C and FIG. 11 correspond.
In step S41, the control unit 30 rotates the first motor 61 and the second motor 62 in the discharge direction. In step S42, the cleaning medium 90 is transported to a position rotated by a predetermined amount (for example, 62 STEP) after the tip of the cleaning medium 90 passes through the fourth sensor 74. After the conveyance, the first motor 61 and the second motor 62 are stopped. As shown in FIG. 7C, the third roller 103 to the seventh roller 107 are positioned on the cleaning medium 90.

  In step S43, the control unit 30 applies the second motor 62 by excitation in the locked state. Accordingly, the cleaning medium 90 is prevented from moving by the fourth roller 104, the fifth roller 105, and the sixth roller 106.

  In step S44, the fourth motor 64 is rotated to adjust the height of the conveyance path. The fourth motor 64 is rotated to reduce the height of the conveyance path so that the turning roller 111 can easily come into contact with the cleaning medium 90.

  In step S45, the third motor 63 is rotated by a predetermined amount in the suction direction. The rotation of the third motor 63 causes the turning roller 111 to idle on the surface of the cleaning medium 90 for a predetermined time, and the turning roller 111 is cleaned. At the same time, the seventh roller 107 on the same axis is also cleaned.

  In step S46, the excitation of the locked state of the second motor 62 is released, the third motor 63 and the fourth motor 64 are rotated, and the height of the conveyance path and the turning roller 111 are moved to the pre-cleaning position. After the movement, the third motor 63 and the fourth motor 64 are stopped.

  If the control unit 30 determines in step S47 that the printing apparatus has a hopper (YES), the process proceeds to state 5. If it is determined that the hopper is not attached (NO), the process jumps to the state 7. The hopper refers to the preceding issuer 32 and the latter issuer 34, and the printing device 20 with a hopper is of the type shown in FIG. The printing device without the hopper is a type in which the front issuer 32, the rear issuer 34, the retracting part 28, and the top and bottom turn part 46 are removed from the printer 20 shown in FIG. 3. Assuming that the printing device is the printing device 20 with a hopper, the process proceeds to state 5.

FIG. 16 is a flowchart illustrating the procedure of the cleaning process in the state 5. State 5 is a process for cleaning the ninth roller 109. FIG. 8B corresponds.
In step S51, the control unit 30 rotates the first motor 61, the second motor 62, and the fifth motor 65 in the suction direction. In step S52, the right end of the cleaning medium 90 passes through the fifth sensor 75 and then is conveyed by a predetermined amount (for example, 146 STEP), and the first motor 61, the second motor 62, and the fifth motor 65 are stopped. As shown in FIG. 8B), the sixth roller 106, the seventh roller 107, the eighth roller 108, and the ninth roller 109 are positioned on the cleaning medium 90.

  In step S53, the control unit 30 applies the second motor 62 by excitation in the locked state. Thereby, the sixth roller 106 and the eighth roller 108 are locked, and the movement of the cleaning medium 90 is prevented.

  In step S54, the fifth motor 65 is rotated in the suction direction by a predetermined number of rotations (for example, 1000 STEP). As the fifth motor 65 rotates, the ninth roller 109 idles on the cleaning medium 90 for a predetermined time, and the ninth roller 109 is cleaned. During this time, the fourth sensor 74 is monitored. If the fourth sensor 74 no longer detects the cleaning medium 90 in step S55 (NO), the control unit 30 proceeds to step 56 and stops the fifth motor 65. This is because it is determined that the cleaning medium 90 has been transported in the suction direction due to insufficient locking.

  If the fourth sensor 74 detects the cleaning medium 90 during the predetermined number of revolutions in step S55 (YES), it is assumed that the lock is sufficient and the cleaning medium 90 does not move during the rotation of the fifth motor 65 in step S54. The process proceeds to step S57.

In step S57, the excitation of the locked state of the second motor 62 is released, and the first motor 61, the second motor 62, and the fifth motor 65 are rotated in the discharging direction.
In step S58, the cleaning medium 90 is conveyed in the discharge direction until the fourth sensor 74 does not detect the cleaning medium 90, that is, until the tip of the cleaning medium 90 is positioned on the discharge side from the fourth sensor 74. This is because the cleaning medium 90 is once taken out from the rear stage portion 26. Then, the process proceeds to state 6.

  FIG. 17 is a flowchart showing the procedure of the cleaning process in the state 6. State 6 is a process for cleaning the tenth roller 110. FIG. 8C corresponds.

  In step S61, the solenoid 80 is turned on and the gate of the retracting unit 28 is opened. In step S62, the first motor 61, the second motor 62, and the fifth motor 65 are rotated in the suction direction.

  In step S63, the cleaning medium 90 is conveyed in the suction direction. After the tip of the cleaning medium 90 is detected by the sixth sensor 76, the first motor 61, the second motor 62, and the fifth motor 65 are stopped after being rotated by a predetermined number of rotations (for example, 164 STEP). As shown in FIG. 8C, the fourth roller 104, the fifth roller 105, the sixth roller 106, the seventh roller 107, the eighth roller 108, and the tenth roller 110 are positioned on the cleaning medium 90.

  In step S64, the control unit 30 applies the second motor 62 by excitation in the locked state. Accordingly, the fourth roller 104, the fifth roller 105, the sixth roller 106, and the eighth roller 108 are locked, and the movement of the cleaning medium 90 is prevented.

  In step S65, the fifth motor 65 is rotated in the suction direction by a predetermined number of rotations (for example, 1000 STEP). As the fifth motor 65 rotates, the tenth roller 110 idles on the cleaning medium 90 for a predetermined time, and the tenth roller 110 is cleaned. During this time, the fourth sensor 74 is monitored.

  In step S66, it is determined whether the fourth sensor 74 is detecting the cleaning medium 90 while the fifth motor 65 is rotating. If the cleaning medium 90 is no longer detected, NO is determined in step S66, the fifth motor 65 is stopped in step S67, and the process proceeds to step S68. This is a case where the cleaning medium 90 is moved by the rotation of the tenth roller 110 due to insufficient locking. On the other hand, if the cleaning medium 90 is detected, step S66 is set to YES, and the process proceeds to step S68 after the predetermined rotation of the fifth motor 65 in step S65.

  In step S68, the excitation of the locked state of the second motor 62 is released, and the first motor 61, the second motor 62, and the fifth motor 65 are rotated in the discharging direction.

  In step S69, the cleaning medium 90 is conveyed in the discharge direction. The fourth sensor 74 conveys until the tip of the cleaning medium 90 detects passage. After the detection, the first motor 61, the second motor 62, and the fifth motor 65 are stopped. In step S70, the solenoid 80 is driven to close the gate of the retracting unit 28. Then, the process proceeds to state 7.

  FIG. 18 is a flowchart showing the procedure of the state 7 and state 8 processes. Further, the state 7 corresponds to FIG. State 7 is a process of cleaning the magnetic head unit provided in the MS unit 36.

  In step S71, the first motor 61, the second motor 62, and the fifth motor 65 are rotated in the discharging direction. In step S72, the cleaning medium 90 is conveyed in the discharge direction. After the seventh sensor 77 detects the passage of the rear end of the cleaning medium 90, the first motor 61, the second motor 62, and the fifth motor 65 are rotated after a predetermined number of rotations (for example, 164 STEP) and further rotated in the discharge direction. Stop. As shown in FIG. 9B), the second roller 102, the third roller 103, the fourth roller 104, and the fifth roller 105 are positioned on the cleaning medium 90.

  In step S73, the second motor 62 is applied by excitation in the locked state. As a result, the fourth roller 104 and the fifth roller 105 are locked to prevent the cleaning medium 90 from moving. In step S74, the control unit 30 controls the drive unit of the MS unit 36 so that a plurality of magnetic read / write heads provided on the back side of the cleaning medium 90 are disposed between the MS head regions shown in FIG. Reciprocating times (for example, twice). It is desirable that a cleaning chemical is also applied to the portion of the cleaning medium 90 that is in contact with the magnetic read / write head. In the cleaning process other than the state 7, since the magnetic head is lowered and retracted to a position lower than the bristles of the brush 94, there is no possibility of being damaged by the brush 94. Then, the process proceeds to state 8.

The state 8 is a process for cleaning the second roller 102 and the third roller 103. The state 8 corresponds to C) of FIG.
In step S81, the first motor 61 is rotated in the discharge direction. The first motor 61 is rotated in a discharging direction (Q direction) by a predetermined number of rotations (for example, 1500 STEP). As shown in FIG. 9C, the second roller 102, the third roller 103, the fourth roller 104, and the fifth roller 105 are positioned on the cleaning medium 90.

  In step S73, since the second motor 62 is already applied with the excitation in the locked state, the movement of the cleaning medium 90 is prevented by the locking of the fourth roller 104 and the fifth roller 105. As the first motor 61 rotates in the discharge direction, the second roller 102 and the third roller 103 idle on the cleaning medium 90 for a predetermined time, and the second roller 102 and the third roller 103 are cleaned.

  In step S82, after the rotation of the first motor 61 in step S81, the excitation of the locked state of the second motor 62 is released, and the first motor 61, the second motor 62, and the fifth motor 65 are rotated in the discharge direction. In step S <b> 83, the cleaning medium 90 is discharged from the passbook insertion / extraction unit 15. Since the first roller 101 is a roller with relatively little dirt, it is excluded from the object to be cleaned, but may naturally be the object to be cleaned. Thus, a series of cleaning processes is completed.

  The cleaning of each optical sensor (the first sensor 71 to the seventh sensor 77) by the brush 94 of the cleaning medium 90 is not particularly described in the flowchart, but the cleaning medium 90 in the state 1 to the state 8 is not described. The light receiving surface and light emitting surface of each optical sensor are cleaned by the transport movement.

  In the description of the above embodiment, it has been described that when the roller is cleaned, the roller is rotated by a predetermined number of rotations, but may be rotated for a predetermined time. The optical sensor used may be a reflective sensor. In addition, the sensor to be monitored is not limited to the sensor at the place of implementation, and can be monitored by other sensors. In the above embodiment, the printing apparatus mounted on the ATM device is used as a base. However, the printing apparatus may be mounted on a passbook entry dedicated machine that does not have a payment function.

  Furthermore, this cleaning device may be provided not in the printing device but in the mark sheet device. The mark sheet device is a device that optically reads information through a mark sheet corresponding to a desired entry item marked on an OMR (Optical Markcard Reader) and converts the selected item into numerical data. This is also because the mark sheet apparatus uses a roller for conveying the mark sheet, and pencil powder and ink written on the mark sheet are transferred to the roller. If the roller is not properly cleaned, it can contaminate the mark sheet and cause errors.

Some of the effects achieved by the above embodiment are listed below.
1 In the system in which one roller is locked (brake) and the other roller is idled on the cleaning medium to clean the roller, the condition is that the idling side driving force is smaller than the braking force. . That is, it is necessary to balance the driving force and braking force on the idling side. On the other hand, in many printing apparatuses, a plurality of rollers are driven by the same drive source. When a plurality of rollers of the same drive source are positioned on the cleaning medium, the plurality of rollers are simultaneously idled. However, a larger locking force is required than in the case of one idling roller. That is, if it is attempted to idle simultaneously with a plurality of rollers, there is a possibility that the idle state cannot be maintained.

  Therefore, a hole is provided in advance in a part of the cleaning medium, and the cleaning medium is moved so that the roller not to be cleaned corresponds to the position of the hole provided in the cleaning medium. Control was made to rotate. In other words, the roller that is not the cleaning target does not drive the cleaning medium, and the cleaning medium is driven only by the driving force of the cleaning target roller. This realizes the idling state of the roller to be cleaned without increasing the locking force even when another roller having the same drive source as the roller to be cleaned exists between the roller to be locked and the roller to be cleaned. Can be cleaned.

  2 Since a short-hair brush for cleaning the surface of the non-contact optical sensor is planted in a part of the cleaning medium for cleaning the roller, the position sensor of the passbook can be cleaned simultaneously with the roller cleaning.

  3 Since the brush is attached to both sides of the cleaning medium, both types of optical sensors can be used to clean both sides without turning over, even if the type is an optical sensor that sandwiches a bankbook. Moreover, since the position where the brush is planted is shifted between the front surface and the back surface, the thickness of the brush prevents the cleaning medium from passing through the sensor portion.

4 Since the magnetic head is also cleaned by the same cleaning medium, the cleaning work is only required once.
Note that the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, all the constituent elements shown in the embodiments may be appropriately combined. Furthermore, constituent elements over different embodiments may be appropriately combined. It goes without saying that various modifications and applications are possible without departing from the spirit of the invention.
