Cash processor and printing device

Abstract

To resolve the problem that, in a printing unit placed on the top surface of a cover of a cash processor, slack may occur in stored rolled media as the cover opens or closes, thereby potentially causing transport malfunctions.SOLUTION: In a cash processor 1 having a printing unit 5 placed on the top surface of a top cover 16, a detection unit 18 for detecting the opening and closing of the top cover 16 detects the opening and closing of the top cover 16 and stores the number of times of detection in a storage unit. When the number of times of detection reaches or exceeds a predetermined number, the rolled media housed within the printing unit 5 is transported by a predetermined distance, thereby reducing the slack in the rolled media to a level that does not interfere with printing.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a cash processing device and a printing device. [Background technology]

[0002] Conventionally, cash processing devices for performing cash withdrawal and deposit transactions have been installed in the backrooms of retail stores, supermarkets, etc. Generally, cash processing devices have a printing unit for printing the details of transactions performed in the cash processing device.

[0003] The printing unit uses a print head to print on rolled media wound into a roll, as in Patent Document 1, for example, and sandwiches the rolled media between the print head and a platen roller, transporting the rolled media by rotating the platen roller.

[0004] In addition, a method of setting rolled media has been proposed, known as the drop-in method, which allows the rolled media to be set with a simple structure by simply inserting it without having to support it through an axis or otherwise secure it. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2008-273060 Summary of the Invention [Problem to be solved by the invention]

[0006] In the drop-in type roll media setting method described above, the roll media is fixed only at one point, between the print head and the platen roller, so the roll media is unstable in the storage space. During operation of the cash processing device, the roll media may move within the storage space, causing the normally tightly wound roll media to loosen. As a result, proper printing may not be possible on the roll media.

[0007] SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and provide a cash processing device and a printing device that can perform appropriate printing on rolled media. [Means for solving the problem]

[0008] In order to achieve the above object, the cash processing device of the present invention has a printing unit that acquires transaction information related to transaction processing, prints the transaction details on a rolled medium wound into a roll, and discharges it from an outlet, a detection unit that detects the state of the cash processing device, and an overall control unit that sends information related to transport control to the printing unit based on the state detected by the detection unit, and the printing unit has a printing control unit that transports the rolled medium toward the outlet in accordance with the information related to transport control acquired from the overall control unit. [Effects of the Invention]

[0009] According to the present invention, it is possible to reduce the occurrence of transport problems caused by loosening of the rolled medium. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant description will be omitted.

[0012] [First embodiment] The first embodiment will be described with reference to the drawings.

[0013] [Configuration of cash processing device] First, the configuration of a cash processing device according to the first embodiment will be described with reference to FIGS. 1 to 5.

The banknote processing unit 8 has a banknote deposit / withdrawal slot 20, a banknote escrow unit 21, a banknote validator 22, a 1,000-yen bill cassette 23, a 5,000-yen bill cassette 24, a 10,000-yen bill cassette 25, a collection cassette 26, and a reject unit 27. Hereinafter, the side facing the user will be defined as the front side of the cash processing device 1, the opposite side will be defined as the rear side, and the top, bottom, left, and right sides as viewed from a user facing the front of the cash processing device 1 will be defined as the upper side, lower side, left side, and right side of the cash processing device 1, respectively.

[0015] The overall control unit 2 controls the entire cash processing device 1. The overall control unit 2 also transmits and receives information to and from the communication unit 42, and receives output regarding the open / close state from the detection unit 18, which will be described later. The memory unit 3 stores the number of times the top cover 16, which will be described later, has been opened and closed. The operation and display unit 4 functions as an operation unit that detects operations by an operator, and as a display unit that displays various screens. The printing unit 5 prints transaction details regarding various transaction processes using cash on a roll-shaped medium. The electromagnetic locking mechanism 6 has a mechanism that electromagnetically locks the front door, not shown. The coin processing unit 7 is located on the left side of the cash processing device 1, and performs predetermined processes regarding coins. The banknote processing unit 8 is located on the right side of the cash processing device 1, and performs predetermined processes regarding banknotes.

[0016] In the coin processing unit 7, the coin slot 9 is an inlet through which coins to be deposited into the coin processing unit 7 are inserted. The coin validator 10 is a validator that uses various sensors to validate the denomination of inserted coins and whether they are valid coins. The coin escrow unit 11 is a holder that temporarily holds coins deposited during validation by the coin validator 10. The coin return box 12 is a return slot that returns coins for which a sales deposit transaction has been canceled or coins that have been determined to be invalid during validation by the coin validator 10, i.e., rejected coins. Here, a sales deposit transaction is a transaction in which sales proceeds and change funds collected from the register are deposited. The dispensing hopper 13 is a storage unit that stores coins in the coin escrow unit 11 by denomination. In a dispensing transaction, various coins are dispensed from the dispensing hopper 13, and in a deposit transaction, various inserted coins are stored in the dispensing hopper 13. The coin collection box 14 is a collection port for transferring and storing the sales proceeds from the dispensing hopper 13 during a sales proceeds collection transaction. The coin dispensing box 15 is a dispensing port for dispensing coins for change, which are prepared as change.

[0017] The top cover 16 is a cover that covers an opening on the top surface of the coin processing unit 7 and covers the entire top surface of the coin processing unit 7. The top cover 16 is provided at the rear of the cash processing device 1 so as to be openable and closable by rotating via a rotation shaft 31 that extends in the left-right direction. The top cover 16 is opened and closed to deal with a malfunction that occurs inside the coin processing unit 7 or for maintenance and inspection. The handle 17 is a portion that grips the top cover 16 when opening or closing it. The detection unit 18 detects the state of the cash processing device 1, and in the first embodiment, is a detection unit that detects the open / closed state of the top cover 16. The detection unit 18 outputs a signal to the overall control unit 2 after detecting the open / closed state described below. For example, it is configured with a photointerrupter. The electromagnetic locking mechanism 19 is a mechanism that electromagnetically locks the top cover 16. In other words, when the electromagnetic lock of the top cover 16 is unlocked, the top cover 16 can be opened.

[0018] In the banknote processing unit 8, the banknote deposit / withdrawal port 20 is a section for depositing banknotes as sales proceeds, etc., or for dispensing banknotes as change reserves, etc. The banknote escrow unit 21 is a section for temporarily stacking banknotes when counting deposited banknotes, etc. The banknote validator 22 is a validation unit that uses various sensors to determine the denomination of deposited banknotes and whether they are valid banknotes or not. The 1,000-yen banknote cassette 23, the 5,000-yen banknote cassette 24, and the 10,000-yen banknote cassette 25 are storage units that store 1,000-yen banknotes, 5,000-yen banknotes, and 10,000-yen banknotes, respectively. The collection cassette 26 is a storage unit that collects sales proceeds. The reject unit 27 is a storage cabinet that stores banknotes that have been determined by the banknote validator 22 to be invalid, i.e., rejected banknotes.

[0019] As shown in Fig. 3, the printing unit 5 is placed on the top surface of the top cover 16, and is located behind the coin slot 9. In addition, the operation and display unit 4 is placed on the top surface of the banknote processing unit 8.

[0020] [Printing section configuration] The configuration of the printing unit 5 will be described in further detail using Figure 4. Figure 4 is an internal side view showing the internal configuration of the printing unit 5. As shown in Figure 4, the printing unit 5 has a printing control unit 41, a communication unit 42, a thermal head 43, a platen roller 44, a cutter 45, an outlet 46, and roll paper 47. The printing control unit 41 controls the communication unit 42, the thermal head 43, the platen roller 44, and the cutter 45 in accordance with information received by the communication unit 42.

[0021] The communication unit 42 transmits and receives information to and from the overall control unit 2. The thermal head 43 prints on the roll paper 47 in accordance with the information received by the communication unit 42. The platen roller 44 receives driving force from a motor (not shown) and rotates in contact with the roll paper 47, transporting the roll paper 47 toward the discharge opening 46. The cutter 45 cuts the roll paper 47 transported by the platen roller 44 toward the discharge opening 46 and discharged from the discharge opening 46. The discharge opening 46 is an opening located in front of the printing unit 5 and serves as a receiving port through which the operator can receive the roll paper 47 cut by the cutter 45. The roll paper 47 is a roll-shaped medium on which various information related to the cash processing device 1 is printed. The roll paper 47 is placed in the storage space of the printing unit 5 in a drop-in manner without being fixed by a shaft or other means. The roll paper 47 is inserted between the thermal head 43 and the platen roller 44 and is fixed at the portion sandwiched between the thermal head 43 and the platen roller 44.

[0022] Although the example in which the roll paper 47 is fixed at the portion sandwiched between the thermal head 43 and the platen roller 44 has been described, a tension roller or the like may also be provided.

[0023] [Printing section operation] The operation of the printing unit 5 will be described with reference to FIG. 4 and FIG. 12(A).

[0024] 12A is a schematic diagram showing the state of the printing unit 5 before printing the transaction details by the printing unit 5. At this time, the leading edge of the roll paper 47 is positioned at the cutter 45.

[0025] When various transaction processes are performed in the cash processing device 1, the overall control unit 2 sends transaction information indicating the details of the transaction process to the communication unit 42. The print control unit 41 controls the thermal head 43 in accordance with the transaction information received by the communication unit 42. Under the control of the print control unit 41, the thermal head 43 prints the transaction details on the roll paper 47. At the same time as the thermal head 43 prints on the roll paper 47, the print control unit 41 causes the platen roller 44 to transport the roll paper 47 toward the discharge outlet 46. After the transaction details are printed on the roll paper 47 and it is transported toward the discharge outlet 46, the state of the print unit 5 changes from that shown in FIG. 12(A) to that shown in FIG. 4.

[0026] The print control unit 41 causes the cutter 45 to cut the transported roll paper 47. After cutting, the state of the print unit 5 changes from that shown in Figure 4 to that shown in Figure 12(A). When all operations are completed, the print control unit 41 sends information indicating that the operations have been completed to the overall control unit 2 via the communication unit 42.

[0027] [Opening and closing the top cover] FIG. 5 is a diagram showing how the top cover 16 of the coin processing unit 7 rotates in the first embodiment. As shown in FIG. 5, the top cover 16 is configured to be rotatable in the direction of arrow A via a rotation shaft 31 extending in the left-right direction at the rear side of the top cover 16. The state in which the top cover 16 is closed (hereinafter referred to as the closed state) is shown by a solid line, and the state in which the top cover 16 is open (hereinafter referred to as the open state) is shown by a dashed dotted line. When the top cover 16 is in the closed state, the front side of the top cover 16 blocks light from the detection unit 18, so the detection unit 18 detects that the top cover 16 is in the closed state. On the other hand, when the top cover 16 is in the open state, the top cover 16 does not block light from the detection unit 18, so the detection unit 18 detects that the top cover 16 is in the open state.

[0028] [State of roll paper in the storage space of the printing unit] As shown in FIG. 5, since the printing unit 5 is placed on the top surface of the top cover 16, the printing unit 5 also moves in conjunction with the rotation of the top cover 16 in the vertical direction.

[0029] Figure 6 shows roll paper 47 unfolded in the storage space of the printing unit 5. The roll paper 47 is fixed only at the part sandwiched between the thermal head 43 and the platen roller 44 in the storage space of the printing unit 5. Therefore, when the printing unit 5 moves in conjunction with the rotation of the top cover 16, the roll paper 47 moves in the storage space of the printing unit 5, vibrating around the part sandwiched between the thermal head 43 and the platen roller 44 as a fulcrum. As a result, the roll paper 47 becomes loose, and as shown in Figure 6, the roll paper 47 unfolds in the storage space of the printing unit 5.

[0030] [Operation of the first embodiment] The above has described the external configuration of the cash processing device 1 and the configuration of the printing unit 5 according to the first embodiment. Next, the operation according to the first embodiment will be described using FIG. 7, FIG. 12(A), and FIG. 12(B). In the following, it is assumed that the cash processing device 1 is powered on. That is, it is assumed that a maintenance person or a store attendant (hereinafter referred to as an operator) opens the top cover 16 while the power is on. FIG. 7 is a flowchart showing the operation flow of the printing unit 5 according to the first embodiment. Also, FIG. 12(B) is a schematic diagram showing the state of the printing unit 5 after the roll paper 47 has been transported a predetermined distance based on information related to transport control, which will be described later.

[0031] First, when the operator performs an action to open top cover 16, top cover 16 rotates, and as a result top cover 16 no longer blocks light from detection unit 18, detection unit 18 detects the open state of top cover 16 and outputs this to overall control unit 2. Thereafter, when the operator performs an action to close top cover 16, top cover 16 rotates, and as top cover 16 blocks light from detection unit 18, detection unit 18 detects the closed state of top cover 16 and outputs this to overall control unit 2.

[0032] When the detection unit 18 detects that the top cover 16 has changed from a closed state to an open state and then changed again to a closed state, and outputs this to the overall control unit 2, the overall control unit 2 determines that the top cover 16 of the coin processing unit 7 has opened and closed once (S201 / Yes), and the overall control unit 2 increments the number of openings and closings stored in the memory unit 3 by one (S202). If the detection unit 18 detects that the top cover 16 is closed (S201 / No), it waits until it detects that the top cover 16 is open.

[0033] If the number of times the top cover 16 has been opened and closed stored in the memory unit 3 is equal to or greater than a predetermined value, the overall control unit 2 sends information regarding transport control, which is information for transporting the roll paper 47 a predetermined distance, to the communication unit 42 of the printing unit 5 (S203 / Yes). When the communication unit 42 receives the information regarding transport control, the printing control unit 41 transports the roll paper 47 a predetermined distance in the direction of the discharge opening 46 (S204). At this time, no printing is performed on the roll paper 47. The state of the printing unit 5 also changes from that shown in Figure 12(A) to that shown in Figure 12(B).

[0034] If the number of times the top cover 16 has been opened and closed stored in the storage unit 3 is smaller than the predetermined value, the process returns to S201 and the same processing is repeated (S203 / No).

[0035] When the transport of roll paper 47 is complete, print control unit 41 causes cutter 45 to cut roll paper 47, which has been transported a predetermined distance and discharged from discharge port 46. After cutting, the state of print unit 5 changes from Figure 12(B) to Figure 12(A), and overall control unit 2 initializes the number of opening and closing cycles stored in memory unit 3 (S205).

[0036] According to the first embodiment described above, even if vibrations are applied to the printing unit 5 when the top cover 16 is opened or closed, the roll paper 47 is transported based on the open / close state detected by the detection unit 18, thereby reducing the loosening of the roll paper 47 to a level that does not interfere with printing.

[0037] [Modification of the first embodiment] The operation of the cash processing device 1 according to the first embodiment has been described above. Below, a modification of the first embodiment will be described.

[0038] In the first embodiment, it is assumed that the power to the cash processing device 1 is on, but it is also assumed that the operator opens and closes the top cover 16 while the power to the cash processing device 1 is off. The operation of the modified example described below reduces the slack in the winding of the roll paper 47 to a level that does not interfere with printing, even when the power is off.

[0039] A modified example of the first embodiment will be described with reference to Fig. 8. Fig. 8 is a flowchart showing the operation flow of the printing unit 5 according to the modified example of the first embodiment. The overall control unit 2, memory unit 3 and detection unit 18 can operate from an internal power supply (not shown) even when the power to the cash processing device 1 is turned off.

[0040] First, when the power supply to the cash processing device 1 is cut off, an operator performs an action to open top cover 16, and when top cover 16 rotates, top cover 16 no longer blocks light from detection unit 18, so detection unit 18 detects the open state of top cover 16 and outputs this to the overall control unit 2. Thereafter, when the operator performs an action to close top cover 16, top cover 16 rotates, and when top cover 16 rotates, top cover 16 blocks light from detection unit 18, so detection unit 18 detects the closed state of top cover 16 and outputs this to the overall control unit 2.

[0041] When the detection unit 18 detects that the top cover 16 has changed from a closed state to an open state and then changed again to a closed state, and outputs this to the overall control unit 2, the overall control unit 2 determines that the top cover 16 of the coin processing unit 7 has opened and closed once (S301 / Yes), and the overall control unit 2 increments the number of times the top cover 16 is opened and closed stored in the memory unit 3 by one (S302). If the detection unit 18 detects that the top cover 16 is closed (S301 / No), the overall control unit 2 waits until it detects that the top cover 16 is open, or until the power is turned on.

[0042] While the detection unit 18 detects that the top cover 16 is closed (S301 / No), it is determined whether the power to the cash processing device 1 has been turned on (S303). When the power to the cash processing device 1 has been turned on (S303 / Yes), if the number of opening and closing operations stored in the memory unit 3 is greater than a predetermined value, the overall control unit 2 sends information related to transport control to the communication unit 42 (S304 / Yes). When the communication unit 42 receives the information related to transport control, the printing control unit 41 transports the roll paper 47 a predetermined distance toward the discharge outlet 46 (S305 / Yes). At this time, no printing is performed on the roll paper 47. If the power has not been turned on in S303 (S303 / No) or if the number of opening and closing operations stored in the memory unit 3 has not reached the predetermined value in S304 (S304 / No), the process returns to S301 and repeats the same process.

[0043] When the transport of the roll paper 47 is completed, the overall control unit 2 initializes the number of opening and closing times stored in the memory unit 3 (S306).

[0044] According to the modified example of the first embodiment described above, even if the printing unit 5 is subjected to vibrations due to the top cover 16 being opened and closed when the power to the cash processing device 1 is turned off, the roll paper 47 can be transported when the power to the cash processing device 1 is turned on, thereby reducing the slack in the roll paper 47 to a level that does not interfere with printing.

[0045] [Second embodiment] The second embodiment will be described with reference to the drawings.

[0046] The cash processing device 101 according to the second embodiment differs from the cash processing device 1 according to the first embodiment in that it has a detection unit 118 instead of the detection unit 18, but is otherwise configured similarly. Vibrations may be applied to the cash processing device 101 from the outside, or the cash processing device 101 itself may vibrate due to the operation of transporting banknotes and coins in the coin processing unit 7 or banknote processing unit 8. In this case, as in the first embodiment, vibrations are applied to the printing unit 5, causing the roll paper 47 to loosen. In the second embodiment, the overall control unit 2 transmits information related to transport control to the communication unit 42 in accordance with the amplitude of the vibrations. Here, amplitude refers to the amplitude of the vibrations.

[0047] The second embodiment differs from the first embodiment in the form and operation of the detection unit, and so the following description will focus on this point.

[0048] FIG. 9 is a diagram showing the internal configuration of a cash processing device 101 according to the second embodiment. The cash processing device 1 according to the first embodiment has a detection unit 18 that detects the open / closed state of the top cover 16 of the coin processing unit 7, but the cash processing device 101 according to the second embodiment has a detection unit 118 that detects the state of vibrations applied to the cash processing device 101 as the state of the cash processing device 101. For example, the detection unit 118 is configured with a vibration detection sensor. Furthermore, by providing the detection unit 118 near the printing unit 5, it is possible to detect with high sensitivity the effect of vibrations on the printing unit 5 caused by the cash processing device 101.

[0049] The operation according to the second embodiment will be described with reference to Fig. 10. Hereinafter, it is assumed that the cash processing device 101 is powered on. Fig. 10 is a flowchart showing the operation flow of the printing unit 5 according to the second embodiment. When the detection unit 118 detects that vibration has been applied to the cash processing device 101 and outputs this to the overall control unit 2 (S401 / Yes), the overall control unit 2 determines whether the amplitude of the vibration applied to the cash processing device 101 is equal to or greater than a predetermined value (S402). When the detection unit 118 does not detect vibration (S401 / No), it waits until vibration is detected.

[0050] If the amplitude is equal to or greater than the predetermined value (S402 / Yes), the overall control unit 2 increases the number of vibrations stored in the memory unit 3 by one (S403). If the amplitude is less than the predetermined value (S402 / No), the process returns to S401 and the same process is repeated.

[0051] When the number of vibrations whose amplitude is equal to or greater than a predetermined value and stored in memory unit 3 reaches a predetermined value, overall control unit 2 sends information about transport control to communication unit 42 of printing unit 5 (S404 / Yes). When communication unit 42 receives the information about transport control, printing control unit 41 transports roll paper 47 a predetermined distance toward discharge outlet 46. At this time, no printing is performed on roll paper 47 (S405). If the number of vibrations is less than the predetermined value (S404 / No), the process returns to S401 and repeats the same process.

[0052] When the transport of the roll paper 47 is completed (S405), the overall control unit 2 initializes the number of vibrations stored in the memory unit 3 (S406).

[0053] According to the second embodiment described above, even if the roll of paper 47 in the printing unit 5 loosens due to vibrations applied to the cash processing device 101, the roll of paper 47 can be transported based on the vibration state detected by the detection unit 118, thereby reducing the loosening of the roll of paper 47 to a level that does not interfere with printing.

[0054] [Modification of the second embodiment] In the second embodiment, it is assumed that vibration is applied while the cash processing device 101 is powered on, but as with the modified example of the first embodiment, it is also assumed that vibration is applied while the cash processing device 101 is powered off. The operation of the modified example described below reduces slack in the winding of the roll paper 47 to a level that does not interfere with printing, even if vibration is applied to the cash processing device 101 while the power is turned off.

[0055] As in the modified example of the first embodiment, the overall control unit 2, memory unit 3 and detection unit 118 can operate using an internal power supply (not shown) even when the power to the cash processing device 101 is turned off.

[0056] In the operation when the power is turned off, a process of determining whether the power of the cash processing device 101 has been turned on (S600 (not shown)) is added between the operations of S403 and S404 in the operation flow of Fig. 10. The other processes are the same as those in the operation flow of Fig. 10.

[0057] In S403, the overall control unit 2 increases the number of vibrations stored in the storage unit 3 by one. When the power supply of the cash processing device 101 is turned on (S600 / Yes), it is determined whether the number of vibrations of which amplitude is equal to or greater than a predetermined value and which are stored in the memory unit 3 is greater than a predetermined value (S404). If the number of vibrations is greater than the predetermined value (S404 / Yes), the overall control unit 2 transmits information relating to conveyance control to the communication unit 42 of the printing unit 5. The subsequent processing is the same as the operation described in the modified example of the first embodiment.

[0058] According to a modified example of the second embodiment, even if vibrations are applied to the printing unit 5 when the power to the cash processing device 101 is turned off, the roll paper 47 is transported when the power to the cash processing device 101 is turned on, so that the slack in the winding of the roll paper 47 can be reduced to a level that does not interfere with printing.

[0059] [Third embodiment] The third embodiment will be described with reference to the drawings. As with the second embodiment, the third embodiment considers a case in which vibrations are applied to the cash processing device 101 from the outside or the cash processing device 101 itself vibrates, causing vibrations to be applied to the printing unit 5 and loosening the roll paper 47. In the third embodiment, the overall control unit 2 transmits information related to transport control to the communication unit 42 in accordance with the frequency of the vibrations applied to the cash processing device 101. Here, the frequency refers to the number of vibrations per unit time.

[0060] In the third embodiment, the internal configuration of the cash processing device 101 is the same as the internal configuration shown in FIG. 9, and therefore a description thereof will be omitted.

[0061] The operation according to the third embodiment will be described with reference to FIG. 11. Hereinafter, it is assumed that the power supply of the cash processing device 101 is turned on. FIG. 11 is a flowchart showing the operation flow of the printing unit 5 according to the third embodiment. When the detection unit 118 detects that vibration has been applied to the cash processing device 101 and outputs the detection result to the overall control unit 2 (S501 / Yes), the overall control unit 2 determines whether the frequency of the vibration applied to the cash processing device 101 is equal to or greater than a predetermined value. In other words, it determines whether the vibration applied to the cash processing device 101 is a small vibration. When the detection unit 118 does not detect any vibration (S501 / No), it waits until it detects a vibration.

[0062] If the vibration frequency is equal to or greater than the predetermined value (S502 / Yes), the overall control unit 2 increases the vibration time stored in the memory unit 3 by the vibration time of the detected vibration (S503). In other words, if the vibration applied to the cash processing device 101 is a small vibration, the vibration time is totaled. If the vibration frequency is less than the predetermined value (S502 / No), the process returns to S501 and repeats the same process.

[0063] When the cumulative vibration time of vibrations stored in memory unit 3, where the vibration frequency is equal to or greater than a predetermined value, reaches a predetermined value, overall control unit 2 sends information about transport control to communication unit 42 of printing unit 5 (S504 / Yes). When communication unit 42 receives the information about transport control, printing control unit 41 transports roll paper 47 a predetermined distance in the direction of discharge outlet 46. At this time, no printing is performed on roll paper 47. If the cumulative vibration time is less than the predetermined value (S504 / No), the process returns to S501 and repeats the same process.

[0064] When the transport of the roll paper 47 is completed (S505), the overall control unit 2 initializes the cumulative vibration time stored in the memory unit 3 (S506).

[0065] According to the third embodiment described above, it is possible to detect that high-frequency vibrations have been applied to the cash processing device 101, regardless of the magnitude of the amplitude. Even if the application of high-frequency vibrations rather than large amplitude vibrations causes the roll paper 47 to become loose, the looseness of the roll paper 47 can be reduced to a level that does not interfere with printing by carrying out the transport of the roll paper 47.

[0066] [Modification of the third embodiment] In the third embodiment, it is assumed that vibration is applied while the cash processing device 101 is powered on, but as with the modified example of the second embodiment, it is also assumed that vibration is applied while the cash processing device 101 is powered off. The operation of the modified example described below can reduce slack in the winding of the roll paper 47 to a level that does not interfere with printing, even if vibration is applied to the cash processing device 101 while the power is turned off.

[0067] As in the modified example of the first embodiment, the overall control unit 2, memory unit 3 and detection unit 118 can operate using an internal power supply (not shown) even when the power to the cash processing device 101 is turned off.

[0068] In the operation when the power is turned off, a process of determining whether the power of the cash processing device 101 is turned on (S600 (not shown)) is added between S503 and S504 in the operation flow of FIG. 11. The other processes are the same as those in the operation flow of FIG. 11.

[0069] In S503, the overall control unit 2 increases the vibration time stored in the memory unit 3 by the vibration time of the detected vibration. When the power of the cash processing device 101 is turned on (S600 / Yes), it is determined whether the cumulative vibration time of vibrations whose vibration frequency is equal to or greater than a predetermined value, stored in the memory unit 3, is greater than a predetermined value (S504). When the cumulative vibration time of the vibrations is greater than the predetermined value (S504 / Yes), the overall control unit 2 transmits information related to conveyance control to the communication unit 42 of the printing unit 5. The subsequent processing is the same as the operation described in the modified example of the first embodiment.

[0070] According to a modified example of the third embodiment, even if the printing unit 5 is subjected to vibrations due to the top cover 16 being opened and closed when the power to the cash processing device 101 is turned off, the roll paper 47 can be transported when the power to the cash processing device 101 is turned on, thereby reducing the slack in the roll paper 47 to a level that does not interfere with printing.

[0071] [Other embodiments] In the first to third embodiments and the modified example of the first embodiment described above, when the communication unit 42 receives information related to transport control, the printing control unit 41 transports the roll paper 47 a predetermined distance in the direction of the discharge opening 46 without printing on the roll paper 47. However, this is not limiting, and the printing control unit 41 may also transport the roll paper 47 a predetermined distance while the printing unit 5 prints predetermined content on the roll paper 47. In this case, the information related to transport control that the overall control unit 2 sends to the communication unit 42 is information indicating that predetermined content will be printed on the roll paper 47 and that the roll paper 47 will be transported a predetermined distance.

[0072] The predetermined content printed on the roll paper 47 by the printing unit 5 may be a message indicating that the printing is to prevent the roll paper 47 from loosening, a message instructing the user to collect the discharged roll paper 47, or a series of numbers and symbols. Multiple predetermined contents to be printed on the roll paper 47 may be stored in the memory unit 3, and the contents may be switchable by setting. The length of the roll paper 47 required for printing may be shorter than the minimum length of the roll paper 47 required for printing transaction details.

[0073] Furthermore, although the printing unit 5 is said to be placed on the upper surface of the upper cover 16 of the coin processing unit 7 in the cash processing device 1, this is not limited to this, and the surface on which the printing unit 5 is placed may be a surface that rotates vertically via a horizontally extending rotation axis, and the printing unit 5 may move in conjunction with this surface.

[0074] Furthermore, while the printing unit 5 is described as being placed on the top surface of the top cover 16 of the coin processing unit 7 in the cash processing device 1, this is not limiting, and the printing unit 5 may be attached so that its rear or side surfaces come into contact with the front door or side door, which rotates left and right about a vertically extending rotation shaft. In this case, the printing unit 5 moves in conjunction with the rotation of the front door or side door, which rotates left and right about a vertically extending rotation shaft, causing the roll paper 47 to loosen. Even in this case, as in the first embodiment and the modified example of the first embodiment, the loosening of the roll paper 47 can be minimized to a level that does not interfere with printing.

[0075] Furthermore, although the printing unit 5 is described as a component of the cash processing device 1, 101, the printing unit 5 may be mounted on the cash processing device as an independent printing device.

[0076] Furthermore, the predetermined value in the first embodiment and the modified example of the first embodiment may be 1. Alternatively, it may be an integer of 2 or more, but it is desirable to set the upper limit at around 60.

[0077] If the predetermined value is 1, the roll paper 47 is transported a predetermined distance each time the top cover 16 is opened and closed, so the effect on the roll paper 47 of opening and closing the top cover 16 can be minimized.

[0078] When the predetermined value is an integer greater than or equal to 2, the number of times the roll paper 47 is transported can be reduced compared to when the roll paper 47 is transported a predetermined distance each time the top cover 16 is opened and closed, thereby reducing the amount of roll paper 47 used.

[0079] It is also desirable that the upper limit of the above-mentioned predetermined value be around 60. By setting the predetermined value at around 60, roll paper 47 is transported a predetermined distance before the roll paper 47 becomes too loose, thereby reducing the amount of roll paper 47 used and reducing the looseness.

[0080] Furthermore, although the present invention has been applied to the cash processing devices 1 and 101, it is not limited to this, and may be applied to devices other than the cash processing devices 1 and 101 as long as they are devices that print on the roll paper 47. For example, the present invention may be applied to automatic transaction devices, self-checkout devices, and settlement machines. [Explanation of symbols]
