Description

The present invention relates to a misinsertion detection program, a misinsertion detection device, and a misinsertion detection method.

Labels with RFID (Radio Frequency Identification) tags attached to roll paper used in blood collection tube preparation devices and the like are peeled off from the roll paper and affixed to blood collection tubes and the like after data is written and printed. In addition, the roll paper after the label is peeled off is wound up by a winding shaft. Therefore, during such normal operation, no label is affixed to the roll paper wound up on the winding shaft. In addition, when setting the roll paper in the blood collection tube preparation device, such as when replacing the roll paper, a certain number of labels affixed to the roll paper, for example 10 sheets, are peeled off by hand from the tip of the roll paper and set on the winding shaft.

However, if a label is forgotten to be peeled off from the roll paper, or if an insufficient number of labels are peeled off, a label with an RFID tag may be mistakenly inserted onto the winding shaft. If an RFID tag label is mistakenly inserted like this, the RFID tag that was mistakenly inserted may end up in the communication area of the RFID reader/writer, which can result in a problem of data not being read/written properly because communication with the RFID tag that should be written is not possible.

In one aspect, the present invention aims to provide a misinsertion detection program, a misinsertion detection device, and a misinsertion detection method that can detect the misinsertion of an RFID tag.

In the first proposal, a misinsertion detection program is provided which causes a misinsertion detection device to read an RFID tag until a certain amount of rotations of a winding shaft that winds up a roll of paper to which an RFID tag is affixed is completed, and then executes a process to determine whether the RFID tag has been misinserted based on the results of reading the RFID tag.

On one hand, it can detect incorrect insertion of an RFID tag.

Below, the embodiments of the mis-insertion detection program, the mis-insertion detection device, and the mis-insertion detection method disclosed in the present application are described in detail with reference to the drawings. Note that the present invention is not limited to these embodiments. Furthermore, each embodiment can be appropriately combined within a range that does not cause inconsistency.

[Misinsertion detection device 10]
First, the misinsertion detection device 10 that is the subject of the operation of the first embodiment will be described. FIG. 1 is a diagram showing an example of the misinsertion detection device 10 according to the first embodiment. An example of the misinsertion detection device 10 is a blood collection tube preparation device installed in a medical facility or the like, but is not limited to the blood collection tube preparation device. FIG. 1 shows the misinsertion detection device 10 as viewed from the front and slightly above, and shows a roll paper 100 set inside the misinsertion detection device 10, a blood collection tube 120 to which a label 110 is affixed and which is discharged, and the like. As shown in FIG. 1, the roll paper 100 is a paper backing 105 to which a plurality of labels 110 are affixed, and each label 110 has an RFID tag 115 attached thereto.

The incorrect insertion detection device 10, for example, prints information about the recipient on the label 110. The incorrect insertion detection device 10 also writes the information about the recipient to the RFID tag 115. In this way, the label 110 and the information about the recipient are associated with each other. The incorrect insertion detection device 10 then peels the labels 110 off the backing paper 105 one by one, attaches them to the blood collection tube 120, and associates the blood collection tube 120 with the information about the recipient.

[Internal configuration of the misinsertion detection device 10]
Next, the internal configuration of the misinsertion detection device 10 will be described. Fig. 2 is a diagram showing an example of the internal configuration of the misinsertion detection device 10 according to the first embodiment. Fig. 2 shows the inside of the misinsertion detection device 10 as viewed from the side. As shown in Fig. 2, the roll paper 100 is set in the misinsertion detection device 10 so that the leading end of the backing paper 105 is wound around the winding shaft 54, and the winding shaft 54 and the platen roll 51 rotate, causing the backing paper 105 to be wound while passing through a predetermined transport path.

As the mount 105 to which the label 110 is affixed passes through a predetermined transport path, information is written to the RFID tag 115 by the RFID reader/writer 50. Strictly speaking, information is written to the RFID tag 115 by an RFID antenna that is built into or externally connected to the RFID reader/writer 50. Although the RFID tag 115 is not shown in FIG. 2 for ease of viewing, the label 110 has an RFID tag 115 attached to it. Information is printed on the label 110 by the platen roll 51 and the thermal head 52. The label 110 is then peeled off from the mount 105 by the peeling plate 53, and the peeled label 110 is affixed to a blood collection tube 120, and the remaining mount 105 is wound up by the winding shaft 54.

In this way, the labels 110 are peeled off by the peeling plate 53, so in normal operation, even if the backing paper 105 is taken up by the winding shaft 54, the labels 110 remain affixed to the backing paper 105 and do not proceed beyond the peeling plate 53. In other words, the misinsertion detection device 10 operates on the premise that no labels 110 are affixed to the backing paper 105 being taken up by the winding shaft 54 after the peeling plate 53. Therefore, when the user sets the roll paper 100 in the misinsertion detection device 10, the operation is such that, for example, about 10 labels 110 are peeled off from the leading edge of the backing paper 105 so that no labels 110 are present after the peeling plate 53.

However, if a label 110 is forgotten to be peeled off or if an insufficient number of labels are peeled off, the roll paper 100 may be set with the label 110 still attached behind the peeling plate 53. This is referred to as the incorrect insertion of the label 110 with the RFID tag 115, or simply the incorrect insertion of the RFID tag 115, and the problems that arise when the RFID tag 115 is incorrectly inserted will be described below.

Figure 3 is a diagram showing an example of an RFID read/write range 80 according to the first embodiment. In the example of Figure 3, the read/write range 80 surrounded by a dashed line is the range in which the RFID reader/writer 50 reads and writes from the RFID tag 115. Also, in Figure 3, for convenience, a flash-like figure is used to represent the RFID reader/writer 50 reading and writing, but the RFID reader/writer 50 does not actually shine. Also, in Figure 3, in order to distinguish between a genuine label 110 and an erroneously inserted label 110, they are represented as label 110-1 and label 110-2, respectively. When a label 110 with an RFID tag 115 is erroneously inserted, there are cases in which both the genuine label 110-1 and the erroneously inserted label 110-2 are present within the read/write range 80, as shown in Figure 3.

On the other hand, although the RFID reader/writer 50 can recognize whether or not the information was successfully written to the label 110, it cannot determine which label 110 the information was successfully written to. Therefore, when multiple labels 110 are present within the read/write range 80, it may happen that the information is not written to the genuine label 110-1, but only to the misinserted label 110-2. Even in such a case, the RFID reader/writer 50 determines that the information was successfully written, so no error notification is given to the user, and it may occur that the user later discovers that the information was not written to the genuine label 110-1.

Therefore, the misinsertion detection device 10 of Example 1 detects the misinsertion of a label 110 with an RFID tag 115 and notifies the user of the occurrence of the misinsertion.

[Functional configuration of the misinsertion detection device 10]
Next, a description will be given of the functional configuration of the misinsertion detection device 10 which is the subject of the operation of the method for detecting misinsertion of the label 110 with the RFID tag 115. Fig. 4 is a functional block diagram showing the functional configuration of the misinsertion detection device 10 according to the first embodiment. As shown in Fig. 4, the misinsertion detection device 10 has a storage unit 20 and a control unit 30.

The memory unit 20 is an example of a storage device that stores various data and programs executed by the control unit 30, and is a storage medium such as a ROM (Read Only Memory) or a RAM (Random Access Memory). The memory unit 20 can store, for example, the number of prints on the label 110 of the roll paper 100, setting information for various functions of the misinsertion detection device 10, and the like. The memory unit 20 can store various data other than the specific examples above.

The control unit 30 is a processing unit that controls the entire misinsertion detection device 10, and is, for example, a processor. The control unit 30 has a rotation control unit 31, a reading unit 32, a judgment unit 33, a notification unit 34, and a decision unit 35. Each processing unit is an example of an electronic circuit possessed by a processor or an example of a process executed by a processor.

The rotation control unit 31 rotates the winding shaft 54, which winds up the roll paper 100, a certain amount in the forward or reverse direction. Here, the forward direction is the direction in which the roll paper 100 is wound. The winding shaft 54 and the platen roll 51 operate in mechanical conjunction. The rotation control unit 31 can also rotate the winding shaft 54 while temporarily stopping it or at a slower speed in order to improve the accuracy of reading the RFID tag 115 by the reading unit 32, which will be described later.

The reading unit 32 reads the RFID tag 115 until the rotation control unit 31 completes a certain amount of rotation of the winding shaft 54. Here, the certain amount of rotation of the winding shaft 54 refers to a certain amount of rotation in the reverse or forward direction of the winding shaft 54, or in both directions. That is, the reading unit 32 reads the RFID tag 115 for the roll paper 100 moving in the reverse or forward direction on a specified transport path due to the rotation of the winding shaft 54 by the rotation control unit 31. This allows the misinsertion detection device 10 to detect the label 110 with the RFID tag 115 that has been misinserted while still attached to the roll paper 100. Note that the reading of the RFID tag 115 by the reading unit 32 can be controlled by setting the execution conditions in advance, for example, when the setting of the roll paper 100 in the misinsertion detection device 10 is completed, or when the feed test of the misinsertion detection device 10 is completed.

The determination unit 33 determines whether or not the RFID tag 115 has been erroneously inserted based on the result of reading the RFID tag 115 by the reading unit 32. For example, when the determination unit 33 successfully reads the RFID tag 115 that remains attached to the roll paper 100 that moves in the reverse or forward direction on a specified transport path due to the rotation of the winding shaft 54 by the rotation control unit 31, the determination unit 33 can determine that the RFID tag 115 has been erroneously inserted.

When the determination unit 33 determines that the RFID tag 115 has been erroneously inserted, the notification unit 34 notifies the occurrence of erroneous insertion of the RFID tag 115. Here, the notification by the notification unit 34 is, for example, outputting a notification sound or displaying an error on a display that the erroneous insertion detection device 10 may have.

The determination unit 35 counts the number of prints on the labels 110 of the roll paper 100, and determines the amount of rotation of the winding shaft 54 based on the number of prints. If the label 110 with the RFID tag 115 is erroneously inserted toward the winding shaft 54, for example, the winding shaft 54 is rotated one revolution while reading the RFID tag 115. However, since the outer diameter of the winding shaft 54 gradually increases as the roll paper 100 is wound up, the amount of rotation of the winding shaft 54 per revolution changes. Therefore, the roll paper 100 is set in the erroneous insertion detection device 10, the number of prints on the labels 110 is counted, and the amount of rotation of the winding shaft 54 is determined based on the number of prints.

Here, the amount of rotation is, for example, the amount of movement of the roll paper 100 along the transport path due to the rotation of the winding shaft 54, or the rotation angle of the winding shaft 54. The counted number of printed sheets is stored in the memory unit 20 by the misinsertion detection device 10, and is reset in response to the roll paper 100 being set in the misinsertion detection device 10. Note that the amount of rotation of the winding shaft 54 may be determined based on a quantity that can determine the amount of rotation of the winding shaft 54 after the roll paper 100 is set in the misinsertion detection device 10, such as the number of labels 110 output from the misinsertion detection device 10, instead of the number of printed sheets.

[Processing details]
Next, the misinsertion detection process performed by the misinsertion detection device 10 according to the first embodiment will be described in detail. The misinsertion detection process is performed during a reset operation of the misinsertion detection device 10, which is performed, for example, when the setting of the roll paper 100 in the misinsertion detection device 10 is complete or when a feed test of the misinsertion detection device 10 is complete. Such execution can be controlled, for example, by storing a flag (hereinafter referred to as a "detection flag") in the memory unit 20 of the misinsertion detection device 10.

More specifically, for example, since the setting of the roll paper 100 and the feed test need to be performed with the cover of the misinsertion detection device 10 open, the detection flag is set to ON in response to the cover being closed, etc. Then, when the detection flag is ON and other execution conditions are met, the misinsertion detection process is executed. The other execution conditions are, for example, that the misinsertion detection device 10 is equipped with an RFID unit such as an RFID reader/writer 50, or that the roll paper 100 with the label 110 with the RFID tag 115 attached is set. These conditions can be determined by the setting information stored in the memory unit 20 of the misinsertion detection device 10. The detection flag is set to OFF when it is determined that no misinsertion has occurred based on the result of reading the RFID tag 115.

When such a detection flag is ON and all other execution conditions are met to execute the misinsertion detection process, the misinsertion detection device 10 first executes a process of retracting the RFID tag 115. When the misinsertion detection process is executed, as shown in Figure 3, since the genuine label 110-1 may be present within the read/write range 80 of the RFID reader/writer 50, a process of retracting the genuine label 110-1 to outside the read/write range 80 is executed so that the genuine label 110-1 is not detected in the misinsertion detection process.

Figure 5 is a diagram showing an example of the retraction process of the RFID tag 115 in the first embodiment. As shown in Figure 5, the misinsertion detection device 10 can retract the regular label 110-1 outside the read/write range 80 by rotating the winding shaft 54 in the reverse direction a certain amount, for example, the equivalent of several labels 110. Note that the example in Figure 5 is an example in which a misinserted label 110-2 exists, but if there is no misinsertion of the label 110 with the RFID tag 115, naturally the misinserted label 110-2 does not exist.

5 before reading the RFID tag 115, it is possible to more accurately detect erroneous insertion of the RFID tag 115. Next, the reading process of the RFID tag 115 for detecting erroneous insertion of the RFID tag 115 will be described.

Figure 6 is a diagram showing an example of the process of reading an RFID tag 115 in the reverse direction according to the first embodiment. As shown in Figure 6, the misinsertion detection device 10 reads the RFID tag 115 while rotating the winding shaft 54 in the reverse direction by a further certain amount, for example, one rotation of the winding shaft 54. Because the regular label 110-1 is not present within the read/write range 80 due to the retraction process of the RFID tag 115 as shown in Figure 5, if reading of the RFID tag 115 is successful, it can be determined that the read RFID tag 115 is that of the misinserted label 110-2.

To improve the accuracy of reading the RFID tag 115, the misinsertion detection device 10 can also temporarily stop or slow down the rotation of the winding shaft 54 while rotating it to read the RFID tag 115. The amount of rotation of the winding shaft 54 for the RFID tag 115 reading process is determined, for example, based on the number of printed labels 110. Even if there is no misinserted label 110-2 on the winding shaft 54 as shown in FIG. 6, there is no proper label 110-1 within the read/write range 80, so if the RFID tag 115 is successfully read, it can be determined that the read RFID tag 115 is the misinserted label 110-2.

Next, the reading process of the RFID tag 115 in the forward direction will be described. Figure 7 is a diagram showing an example of the reading process of the RFID tag 115 in the forward direction in Example 1. The reading process of the RFID tag 115 in the forward direction is performed after rotating the winding shaft 54 in the reverse direction a certain amount as shown in Figure 6. Similarly to the reverse direction, the reading process of the RFID tag 115 in the forward direction is performed by rotating the winding shaft 54 in the forward direction a certain amount as shown in Figure 7. As a result, if the reading of the RFID tag 115 is successful, it can be determined that the read RFID tag 115 is that of the misinserted label 110-2.

The amount of rotation of the winding shaft 54 in the forward direction may be the same as the amount of rotation of the winding shaft 54 in the reverse direction shown in Figure 6. As in the reverse direction, the misinsertion detection device 10 can improve the accuracy of reading the RFID tag 115 by temporarily stopping or slowing down the winding shaft 54 while reading the RFID tag 115.

6 and 7, the process of reading the RFID tag 115 in the reverse and forward directions to detect the misinsertion of the label 110 with the RFID tag 115 has been described. Note that the misinsertion detection device 10 can read the RFID tag 115 in both the reverse and forward directions to improve the rate of detection of misinsertion, but may also read the RFID tag 115 in only one of the directions.

Next, a method for determining the amount of rotation of the winding shaft 54 will be described. FIG. 8 is a diagram showing an example of the winding shaft 54 when the number of printed sheets of the label 110 according to the first embodiment increases. As shown in FIG. 8, when the number of printed sheets of the label 110 increases, the amount of the backing paper 105 wound around the winding shaft 54 increases, and the outer diameter of the winding shaft 54 gradually increases. Therefore, for example, the amount of rotation of one rotation of the winding shaft 54 when performing the reading process of the RFID tag 115 varies depending on the number of printed sheets. Therefore, for example, the number of printed sheets of the label 110 is counted after the roll paper 100 is set in the misinsertion detection device 10, and the amount of rotation of the winding shaft 54 is determined based on the number of printed sheets.

9 is a diagram showing an example of the relationship data between the number of printed sheets and the return amount according to the first embodiment. The misinsertion detection device 10 stores such relationship data in the memory unit 20, and obtains the "return amount (step)" by searching for the "number of printed sheets (less than)" using the counted number of printed sheets as a search key. In the example of FIG. 9, the "number of printed sheets (less than)" is expressed in units of less than, and for example, when the number of printed sheets is 300, the "return amount (step)" corresponding to the "number of printed sheets (less than)" of 500 (less) is obtained. The "return amount (step)" indicates the amount of movement of the roll paper 100 relative to the transport path, but may be another amount, such as the rotation angle of the winding shaft 54. In this way, the relationship between the number of printed sheets and the movement amount of the roll paper 100 and the rotation angle of the winding shaft 54 is stored as data in the memory unit 20, so that the amount of rotation of the winding shaft 54 can be determined according to the number of printed sheets.

Note that the relationship data in Figure 9 is merely an example, and the granularity of the "number of printed sheets (less than)" may be finer, or the number of printed sheets may be set in a data format indicating a range, such as 10 sheets or less, 11 sheets to 200 sheets, 201 sheets to 500 sheets, 501 sheets or more, etc.

[Process flow]
Next, the flow of the mis-insertion detection process performed by the mis-insertion detection device 10 according to the first embodiment will be described below with reference to FIG 10. The flow of the mis-insertion detection process according to the first embodiment will be described with reference to FIG 10.

First, as shown in FIG. 10, the misinsertion detection device 10 executes a reset operation (step S101). The reset operation is an initialization and reconfiguration process of various setting information that is executed, for example, when the setting of the roll paper 100 in the misinsertion detection device 10 is completed, or when a feed test of the misinsertion detection device 10 is completed. The reset operation also controls the label 110 affixed to the roll paper 100 to move to an appropriate position. Note that the appropriate position is, for example, a position between or in front of the platen roll 51 and the thermal head 52 so that information can be properly printed on the label 110.

After the reset operation is performed, the misinsertion detection device 10 then refers to the setting information in the memory unit 20 to determine whether or not the misinsertion detection device 10 is equipped with an RFID unit such as an RFID reader/writer 50 (step S102). If an RFID unit is not equipped (step S102: No), writing to the RFID tag 115 and misinsertion do not occur in the first place, and the misinsertion detection process shown in FIG. 10 ends.

On the other hand, if an RFID unit is installed (step S102: Yes), the misinsertion detection device 10 refers to the setting information in the memory unit 20 and determines whether or not an RFID tag 115 is set in the misinsertion detection device 10 (step S103). The RFID tag 115 being set in the misinsertion detection device 10 means that a roll of paper 100 with a label 110 with an RFID tag 115 attached is set in the misinsertion detection device 10. Even if the RFID tag 115 is not set (step S103: No), writing to the RFID tag 115 and misinsertion do not occur, and the misinsertion detection process shown in FIG. 10 ends.

On the other hand, if the RFID tag 115 is set (step S103: Yes), the misinsertion detection device 10 refers to the memory unit 20 and determines whether the detection flag is ON/OFF (step S104). If the detection flag is OFF (step S104: No), the RFID tag 115 has not been misinserted, and the misinsertion detection process shown in Figure 10 ends. Note that the order of the determination processes in steps S102 to S104 does not have to be as shown in Figure 10, and they may be executed in parallel.

On the other hand, if the detection flag is ON (step S104: Yes), the misinsertion detection device 10 rotates the winding shaft 54 in the reverse direction by a second amount (step S105). Here, the second amount is the amount of rotation for moving the genuine label 110-1 out of the read/write range 80 as shown in FIG. 5, for example, the amount of rotation for moving approximately several labels 110.

Next, the misinsertion detection device 10 starts reading the RFID tag 115 (step S106).

Next, the misinsertion detection device 10 rotates the winding shaft 54 in the reverse direction by a first amount (step S107). This allows the misinsertion detection device 10 to read the RFID tag 115 for the roll paper 100 moving in the reverse direction on the transport path. Note that steps S106 and S107 may be reversed to rotate the winding shaft 54 before starting to read the RFID tag 115. To improve the accuracy of reading the RFID tag 115, the misinsertion detection device 10 may rotate the winding shaft 54 while temporarily stopping it or at a low speed.

Next, the misinsertion detection device 10 rotates the winding shaft 54 a first amount in the forward direction (step S108). This is performed to read the RFID tag 115 while moving the roll paper 100, which was moved in the reverse direction along the transport path in step S107, in the forward direction so as to return it to its original position, in order to improve the detection rate of misinsertion of the RFID tag 115.

Next, the misinsertion detection device 10 finishes reading the RFID tag 115 (step S109). If the RFID tag 115 is to be read only when rotating in the reverse direction (step S107), steps S108 and S109 may be reversed, and the winding shaft 54 may be rotated in the forward direction after finishing reading the RFID tag 115.

Next, the misinsertion detection device 10 determines whether or not the RFID tag 115 has been successfully read (step S110). If the RFID tag 115 has been successfully read (step S110: Yes), the misinsertion detection device 10 determines that the RFID tag 115 has been misinserted, and notifies the user of the occurrence of the misinsertion by outputting a notification sound or the like (step S111). After step S111 is executed, the misinsertion detection process shown in FIG. 10 ends, but after the user removes the misinserted label 110-2, the misinsertion detection process is executed again to determine whether the misinsertion of the RFID tag 115 has been resolved.

On the other hand, if the reading of the RFID tag 115 fails (step S110: No), the misinsertion detection device 10 determines that the misinsertion of the RFID tag 115 has not occurred, and rotates the winding shaft 54 in the forward direction by a second amount (step S112). This is performed to return the genuine label 110-1 that was retracted outside the read/write range 80 in step S105 to its original position. Also, if the reading of the RFID tag 115 fails (step S110: No), the detection flag can be set to OFF. This allows the misinsertion detection device 10 to determine that the misinsertion of the RFID tag 115 has not occurred or has been resolved, and to control so that the misinsertion detection process is not executed repeatedly. After execution of step S112, the misinsertion detection process shown in FIG. 10 ends.

[effect]
As described above, the misinsertion detection device 10 reads the RFID tag 115 before a certain amount of rotation of the winding shaft 54 that winds up the roll paper 100 to which the RFID tag 115 is affixed is completed, and then performs a process to determine whether the RFID tag 115 has been misinserted based on the results of the read.

In this way, the misinsertion detection device 10 can detect the misinsertion of an RFID tag 115 by reading the misinserted RFID tag 115 that is not peeled off from the roll paper 100 and is in the read/write range 80 of the RFID tag 115 where it should not be.

In addition, the misinsertion detection device 10 further performs a process of rotating the winding shaft 54 that winds the roll paper 100 in the reverse direction by a first amount, and rotating the winding shaft 54 in the forward direction by the first amount, and the process of performing reading performed by the misinsertion detection device 10 includes a process of performing reading until the first amount of rotation in at least one of the reverse direction and the forward direction is completed.

In this way, the misinsertion detection device 10 can detect the misinsertion of the RFID tag 115 by reading the misinserted RFID tag 115 in the read/write range 80 of the RFID tag 115 while rotating the winding shaft 54 in the reverse or forward direction.

In addition, if it is determined that a misinsertion has occurred, the misinsertion detection device 10 further executes a process of notifying the occurrence of the misinsertion.

This allows the misinsertion detection device 10 to notify the user that the RFID tag 115 has been misinserted.

In addition, the misinsertion detection device 10 further performs a process of rotating the winding shaft 54 in the reverse direction a second amount before rotating the winding shaft 54 in the reverse direction a first amount.

As a result, the misinsertion detection device 10 can move the regular label 110-1 outside the read/write range 80 of the RFID tag 115 so that it cannot be detected, and can accurately detect only the misinserted label 110-2.

In addition, if the misinsertion detection device 10 determines that no misinsertion has occurred, it further executes a process of rotating the winding shaft 54 in the forward direction by a second amount.

This allows the misinsertion detection device 10 to return the genuine label 110-1, which had been moved outside the reading and writing range 80 of the RFID tag 115, to its original position and resume normal operation.

In addition, the process of reading executed by the misinsertion detection device 10 is executed in response to determining that a detection flag is ON, which is set to ON when the setting of the roll paper 100 in the misinsertion detection device 10 is completed or when the feed test of the misinsertion detection device 10 is completed, and is set to OFF when it is determined based on the reading result that no misinsertion has occurred.

This enables the misinsertion detection device 10 to detect the misinsertion of the RFID tag 115, which is likely to occur after the misinsertion detection device 10 is reset.

In addition, the misinsertion detection device 10 counts the number of printed sheets on the label 110 of the roll paper 100, and further performs a process of determining a fixed amount of rotation based on the number of printed sheets.

This allows the misinsertion detection device 10 to more accurately determine, for example, the amount of rotation of one revolution of the winding shaft 54, whose outer diameter gradually increases as the roll paper 100 is wound up.

In addition, at least one of the process of rotating a first amount in the reverse direction and the process of rotating a first amount in the forward direction performed by the misinsertion detection device 10 includes a process of rotating the take-up shaft 54 a first amount while temporarily pausing it.

This enables the misinsertion detection device 10 to improve the accuracy of reading the RFID tag 115.

In addition, the process of rotating in the reverse direction a first amount and the process of rotating in the forward direction a first amount performed by the misinsertion detection device 10 include a process of slowing down the rotation speed of the winding shaft 54 when reading the RFID tag 115 compared to when reading is not performed.

This enables the misinsertion detection device 10 to improve the accuracy of reading the RFID tag 115.

In other words, the specific form of distribution and integration of each device is not limited to that shown in the figure. In other words, all or part of them can be functionally or physically distributed or integrated in any unit depending on various loads, usage conditions, etc. For example, the judgment unit 33 and notification unit 34 of the misinsertion detection device 10 can be integrated.

Furthermore, each processing function performed by each device may be realized, in whole or in part, by a CPU and a program analyzed and executed by the CPU, or may be realized as hardware using wired logic.

[Hardware configuration of the misinsertion detection device 10]
The units shown in Fig. 4 are connected to each other via a bus or the like. The control unit 30 reads out a program that executes each process from the storage unit 20 and expands it in a memory area, thereby operating a process that executes each function described in Fig. 4. For example, this process executes a function similar to that of each processing unit of the misinsertion detection device 10. Specifically, for example, the control unit 30 reads out a program having a function similar to that of the rotation control unit 31, the reading unit 32, etc. Then, the control unit 30 executes a process that executes a process similar to that of the rotation control unit 31, the reading unit 32, etc.

In this way, the misinsertion detection device 10 operates as an information processing device that executes each process by reading and executing the program. The program can be distributed over a network such as the Internet. The program can also be recorded on a computer-readable recording medium such as a hard disk, flexible disk (FD), CD-ROM, MO (Magneto-Optical disk), or DVD (Digital Versatile Disc), and can be executed by being read from the recording medium by the misinsertion detection device 10.

So far, we have described embodiments of the present invention, but the present invention may be embodied in various different forms other than the embodiments described above.
