Computer readable recording medium, error insertion detection device and error insertion detection method

Abstract

In an apparatus for preparing a blood sample tube, a label with an RFID tag may be mistakenly inserted into a take-up shaft when the label has not been removed from a paper roll or the number of labels removed is insufficient, etc. There is a problem that when a label with an RFID tag is mistakenly inserted, the mistakenly inserted RFID tag may end up existing in the communication area of ​​an RFID reader / writer, thereby failing to communicate with the RFID tag that should have been originally written, and reading / writing data is not performed normally. Therefore, the present invention provides a recording medium having an error insertion detection program stored therein, characterized in that an error insertion detection device is caused to read the RFID tag until the take-up shaft of the take-up paper roll completes a certain amount of rotation, the RFID tag adheres to the paper roll, and based on the reading result of the RFID tag, it is determined whether an error insertion of the RFID tag has occurred. This makes it possible to detect the error insertion of the RFID tag.

Description

Technical Field

[0001] The present invention relates to a computer-readable recording medium, an error insertion detection device and an error insertion detection method. Background Art

[0002] A label with a radio frequency identification (RFID) tag is attached to a paper roll for a blood collection tube preparation device, etc., is peeled off from the paper roll after data writing and printing are performed, and is attached to a blood collection tube, etc. In addition, the paper roll is wound up by a winding shaft after the label is peeled off. Therefore, during such normal operation, the label is not attached to the paper roll wound up by the winding shaft. In addition, in order to set the paper roll in the blood collection tube preparation device, for example, when the paper roll is replaced, the label attached to the paper roll is set to the winding shaft, for example, by manually peeling off a certain number of labels (for example, about ten labels) from the end of the paper roll.

[0024] Hereinafter, embodiments of the recording medium in which the error insertion detection program is stored, the error insertion detection device, and the error insertion detection method disclosed in the present application will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to these embodiments. In addition, these embodiments can be appropriately combined within a consistent range.

[0025] First embodiment

[0026] [Error insertion detection device 10]

[0027] First, the erroneous insertion detection device 10 serving as an operating subject of the first embodiment will be described. Figure 1 1 is a diagram showing an example of the erroneous insertion detection device 10 according to the first embodiment. One example of the erroneous insertion detection device 10 is a blood collection tube preparation device of a medical facility, etc. However, the erroneous insertion detection device 10 is not limited to the blood collection tube preparation device. Figure 1 The erroneous insertion detection device 10 is shown as viewed from the front and slightly above, and also shows a paper roll 100 disposed inside the erroneous insertion detection device 10, a blood collection tube 120 discharged after a label 110 is attached, and the like. Figure 1 As shown, the paper roll 100 is obtained by attaching a plurality of tags 110 to a mount 105 , and an RFID tag 115 is attached to each of the tags 110 .

[0028] For example, the erroneous insertion detection device 10 prints information about the person whose blood is sampled onto the label 110. In addition, the erroneous insertion detection device 10 writes information about the person whose blood is sampled onto the RFID tag 115. In this way, the label 110 is associated with the information about the person whose blood is sampled. Then, the erroneous insertion detection device 10 peels the label 110 off the backing paper 105 one by one, sticks the label 110 to the blood sampling tube 120, and associates the blood sampling tube 120 with the information about the person whose blood is sampled.

[0029] [Internal Configuration of Error Insertion Detection Device 10]

[0030] Next, the internal configuration of the erroneous insertion detection device 10 will be described. Figure 2 : is a diagram showing an example of the internal configuration of the erroneous insertion detection device 10 according to the first embodiment. Figure 2 FIG. 2 shows the interior of the error insertion detection device 10 viewed from the side. Figure 2 As shown, the paper roll 100 is arranged in the wrong insertion detection device 10 so that the end of the backing paper 105 is wound around the winding shaft 54, and when the winding shaft 54 ​​and the platen roller 51 rotate, the backing paper 105 is wound by the winding shaft 54 ​​while passing through a predetermined conveying path.

[0031] Furthermore, when the backing paper 105 to which the label 110 is attached passes through a predetermined conveying 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 built into or externally connected to the RFID reader / writer 50. Figure 2 Although the RFID tag 115 is not shown in the figure, the RFID tag 115 is attached to the label 110. In addition, information is printed on the label 110 by the platen roller 51 and the thermal head 52. Then, the label 110 is peeled off from the backing paper 105 by the peeling plate 53, the peeled label 110 is attached to the blood collection tube 120 or the like, and the remaining backing paper 105 is wound up by the winding shaft 54.

[0032] In this way, the label 110 is peeled off by the peeling plate 53. Therefore, in normal operation, even if the backing paper 105 is taken up by the take-up shaft 54, the backing paper 105 does not travel beyond the peeling plate 53, where the label 110 is still attached. In other words, assuming that the label 110 is not attached to the backing paper 105 taken up beyond the peeling plate 53 by the take-up shaft 54, the wrong insertion detection device 10 operates. Therefore, when the user sets the paper roll 100 in the wrong insertion detection device 10, for example, the user also peels off about ten labels 110 from the end of the backing paper 105 to prevent the label 110 from existing beyond the peeling plate 53.

[0033] However, when the label 110 is left or not enough labels are peeled off from the paper roll 100, the paper roll 100 may be arranged such that the label 110 is still attached beyond the peeling plate 53. This is indicated as an erroneous insertion of the label 110 with the RFID tag 115, or simply as an erroneous insertion of the RFID tag 115. Next, a problem caused by the erroneous insertion of the RFID tag 115 will be described.

[0034] Figure 3 is a diagram showing an example of a read / write range 80 of an RFID according to the first embodiment. Figure 3 In the example of FIG. 1 , the read / write range 80 surrounded by the dotted line is the range in which the RFID reader / writer 50 reads and writes the RFID tag 115. Figure 3 In the figure, for convenience, a flashing form of illustration is used to indicate a state in which the RFID reader / writer 50 performs reading and writing. However, in fact, the RFID reader / writer 50 does not flash, etc. In addition, in Figure 3 In order to distinguish between a normal tag 110 and an erroneously inserted tag 110, the tags are represented as tag 110-1 and tag 110-2. Figure 3When the tag 110 with the RFID identification 115 is erroneously inserted as shown, both the normal tag 110 - 1 and the erroneously inserted tag 110 - 2 may be present in the read / write range 80 .

[0035] On the other hand, although the RFID reader / writer 50 can identify whether information is written to the tag 110, the RFID reader / writer 50 cannot determine which tag 110 the information is successfully written to. Therefore, if there are a plurality of tags 110 in the read / write range 80, it is possible that information is written only to the erroneously inserted tag 110-2, but no information is written to the normal tag 110-1. Even in such a case, the RFID reader / writer 50 determines that the information is successfully written. Therefore, an error notification will not be sent to the user, and a problem such as finding that information is not written to the normal tag 110-1 occurs later.

[0036] Thus, the erroneous insertion detection device 10 according to the first embodiment detects erroneous insertion of the tag 110 with the RFID marker 115 and notifies the user of the erroneous insertion.

[0037] [Functional Configuration of the Error Insertion Detection Device 10]

[0038] Next, a functional configuration of the erroneous insertion detection device 10 serving as an operating subject of the erroneous insertion detection method of the tag 110 with the RFID identifier 115 will be described. Figure 4 1 is a functional block diagram showing the functional configuration of the error insertion detection device 10 according to the first embodiment. Figure 4 As shown, the error insertion detection device 10 includes a storage unit 20 and a control unit 30 .

[0039] The storage unit 20 is an example of a storage device that stores various types of data and a computer program executed by the control unit 30, and is, for example, a storage medium such as a read-only memory (ROM) and a random access memory (RAM). For example, the storage unit 20 may store the number of prints of the label 110 on the paper roll 100, setting information of various functions of the erroneous insertion detection device 10, and the like. In addition to the above-mentioned specific examples, various types of data may be stored in the storage unit 20.

[0040] The control unit 30 is a processing unit that controls the entire error insertion detection device 10, and is, for example, a processor, etc. The control unit 30 includes a rotation control unit 31, a reading unit 32, a determination unit 33, a notification unit 34, and a decision unit 35. Each processing unit is an example of an electronic circuit included in a processor or an example of a process executed by a processor.

[0041] The rotation control unit 31 rotates the take-up shaft 54 ​​of the take-up paper roll 100 by a fixed amount in the forward direction or the reverse direction. In this example, the forward direction is the direction in which the take-up paper roll 100 is facing. In addition, the take-up shaft 54 ​​and the platen roller 51 are mechanically operated in an interlocking manner. In order to improve the accuracy of the reading unit 32 reading the RFID tag 115 (which will be described below), the rotation control unit 31 can also rotate the take-up shaft 54 ​​when temporarily stopping the take-up shaft 54 ​​or reducing the speed of the take-up shaft 54.

[0042] Before the rotation of the take-up shaft 54 ​​by the rotation control unit 31 is completed by the fixed amount, the reading unit 32 reads the RFID tag 115. In this example, rotating the take-up shaft 54 ​​by the fixed amount is rotating the take-up shaft 54 ​​by the fixed amount in the reverse direction or the forward direction or in both directions. In other words, the reading unit 32 reads the RFID tag 115 on the paper roll 100 moving along the predetermined conveying path in the reverse direction or the forward direction by rotating the take-up shaft 54 ​​by the rotation control unit 31. Therefore, the wrong insertion detection device 10 can detect the label 110 with the RFID tag 115 that is mistakenly inserted when attached to the paper roll 100. Note that setting the execution condition in advance makes it possible to control the reading of the RFID tag 115 by the reading unit 32 so that, for example, the reading is performed when the paper roll 100 is completely set in the wrong insertion detection device 10 or when the feeding test of the wrong insertion detection device 10 is completed.

[0043] The determination unit 33 determines the erroneous insertion of the RFID tag 115 based on the reading result of the RFID tag 115 by the reading unit 32. For example, when the RFID tag 115 attached to the paper roll 100 moving along the predetermined conveying path in the reverse direction or the forward direction when the rotation control unit 31 rotates the take-up shaft 54 ​​is successfully read, the determination unit 33 may determine that the RFID tag 115 is erroneously inserted.

[0044] When the determination unit 33 determines that the RFID tag 115 is erroneously inserted, the notification unit 34 notifies that erroneous insertion of the RFID tag 115 has occurred. In this example, for example, the notification by the notification unit 34 includes outputting a notification sound, displaying an error on a display that may be provided on the erroneous insertion detection device 10, and the like.

[0045] The determination unit 35 counts the number of prints of the label 110 on the paper roll 100, and determines the amount of rotation of the winding shaft 54 ​​based on the number of prints. For example, when the label 110 with the RFID tag 115 is mistakenly inserted into the winding shaft 54, the RFID tag 115 is read by rotating the winding shaft 54 ​​one turn. However, since the outer diameter of the winding shaft 54 ​​gradually increases as the paper roll 100 is wound, the amount of rotation of the winding shaft 54 ​​per turn changes. Thus, the number of prints of the label 110 is counted after the paper roll 100 is set in the wrong insertion detection device 10, and the amount of rotation of the winding shaft 54 ​​is determined based on the number of prints.

[0046] In this example, for example, the rotation amount is the movement amount of the paper roll 100 moved along the conveying path by the rotation of the take-up shaft 54 ​​or the rotation angle of the take-up shaft 54. In addition, the counted number of prints is stored in the storage unit 20 by the erroneous insertion detection device 10, and is reset in response to the paper roll 100 set in the erroneous insertion detection device 10. Instead of the number of prints, the rotation amount of the take-up shaft 54 ​​may be determined based on the number of times the rotation amount of the take-up shaft 54 ​​can be determined after the paper roll 100 is set in the erroneous insertion detection device 10 (for example, the number of labels 110 output from the erroneous insertion detection device 10).

[0047] [Details of the process]

[0048] Next, the erroneous insertion detection process performed by the erroneous insertion detection device 10 according to the first embodiment will be described in detail. For example, the erroneous insertion detection process is performed during the reset operation of the erroneous insertion detection device 10, which is performed when the paper roll 100 is completely set in the erroneous insertion detection device 10, when the feeding test of the erroneous insertion detection device 10 is completed, etc. For example, such an operation can be controlled by holding a flag (hereinafter, referred to as a "detection flag") in the storage unit 20 of the erroneous insertion detection device 10.

[0049] More specifically, for example, it is necessary to set the paper roll 100 and perform the feeding test by opening the cover of the error insertion detection device 10. Therefore, the detection flag is set to on in response to the cover being closed, etc. Then, when the detection flag is on and when other execution conditions are met, the error insertion detection process is performed. For example, the other execution conditions include: (1) an RFID unit (such as an RFID reader / writer 50) is installed in the error insertion detection device 10; (2) the paper roll 100 to which the label 110 with the RFID identifier 115 is attached is set in the error insertion detection device 10, etc. These conditions can be determined by the setting information stored in the storage unit 20 of the error insertion detection device 10. When it is determined that the error insertion has not occurred based on the reading result of the RFID identifier 115, the detection flag is set to off.

[0050] When the detection flag is turned on and when all other execution conditions are met in this way, the error insertion detection process is executed. Then, the error insertion detection device 10 first executes the storage process of the RFID tag 115. Figure 3 As shown, when the error insertion detection process is performed, the normal tag 110-1 may exist within the read / write range 80 of the RFID reader / writer 50. Therefore, during the error insertion detection process, the normal tag 110-1 is kept outside the read / write range 80, so that the normal tag 110-1 is not detected.

[0051] Figure 5 1 is a diagram showing an example of a storage process of the RFID tag 115 according to the first embodiment. Figure 5 As shown, by rotating the take-up shaft 54 ​​in the reverse direction by a fixed amount (for example, by rotating approximately several tags 110), the error insertion detection device 10 can keep the normal tag 110-1 outside the read / write range 80. Figure 5 In the example of , there is an erroneously inserted tag 110 - 2 . However, when the tag 110 with the RFID tag 115 is not erroneously inserted, naturally, there is no erroneously inserted tag 110 - 2 .

[0052] like Figure 5 As shown, by performing the saving process of the RFID tag 115 before the reading process of the RFID tag 115, the erroneous insertion of the RFID tag 115 can be detected more accurately. Next, the reading process of the RFID tag 115 to detect the erroneous insertion of the RFID tag 115 will be described.

[0053] Figure 6 1 is a diagram showing an example of a reading process of the RFID tag 115 in the reverse direction according to the first embodiment. Figure 6 As shown, the erroneous insertion detection device 10 reads the RFID tag 115 when the take-up shaft 54 ​​is further rotated in the reverse direction by a fixed amount (for example, one rotation of the take-up shaft 54). Figure 5 In the storage process of the RFID tag 115 shown, the normal tag 110 - 1 does not exist in the read / write range 80 , so when the RFID tag 115 is successfully read, it can be determined that the read RFID tag 115 is in the erroneously inserted tag 110 - 2 .

[0054] In order to improve the accuracy of reading the RFID tag 115, the erroneous insertion detection device 10 may also read the RFID tag 115 by rotating the take-up shaft 54 ​​while temporarily stopping the take-up shaft 54 ​​or reducing the speed of the take-up shaft 54. In addition, for example, the rotation amount of the take-up shaft 54 ​​for reading the RFID tag 115 is determined based on the number of prints of the label 110. In addition, as Figure 6 As shown, when the erroneously inserted tag 110-2 does not exist on the take-up reel 54, the normal tag 110-1 also does not exist within the read / write range 80. Therefore, when the RFID tag 115 is successfully read, it can be determined that the read RFID tag 115 is in the erroneously inserted tag 110-2.

[0055] Next, a reading process of the RFID tag 115 in the forward direction will be described. Figure 7 1 is a diagram showing an example of a reading process of the RFID tag 115 in the forward direction according to the first embodiment. Figure 6 After the take-up shaft 54 ​​is rotated in the reverse direction by a fixed amount, the reading process of the RFID tag 115 in the forward direction is performed. Figure 7 As shown, similar to the reading process of the RFID tag 115 in the reverse direction, the reading process of the RFID tag 115 in the forward direction is performed by rotating the take-up shaft 54 ​​by a fixed amount in the forward direction. As a result, when the RFID tag 115 is successfully read, it can be determined that the read RFID tag 115 is in the incorrectly inserted tag 110-2.

[0056] The rotation amount of the take-up shaft 54 ​​in the positive direction can be related to Figure 6 In addition, similar to the case of the reverse direction, the wrong insertion detection device 10 can improve the accuracy of reading the RFID tag 115 by reading the RFID tag 115 while temporarily stopping the take-up shaft 54 ​​or reducing the speed of the take-up shaft 54.

[0057] refer to Figure 6 and Figure 7 , the reading process of the RFID tag 115 in the reverse direction and the forward direction has been described to detect the erroneous insertion of the tag 110 with the RFID tag 115. In order to improve the detection rate of the erroneous insertion, the erroneous insertion detection device 10 can read the RFID tag 115 in both the reverse direction and the forward direction. However, the erroneous insertion detection device 10 can also read the RFID tag 115 in only one direction.

[0058] Next, a method of determining the rotation amount of the take-up shaft 54 ​​will be described. Figure 8 1 is a diagram showing an example of the take-up shaft 54 ​​when the number of prints of the label 110 according to the first embodiment increases. Figure 8As shown, when the number of prints of the label 110 increases, the amount of the backing paper 105 wound by the winding shaft 54 ​​increases, thereby gradually increasing the outer diameter of the winding shaft 54. Therefore, for example, when the reading process of the RFID tag 115 is performed, the rotation amount per one turn of the winding shaft 54 ​​is changed according to the number of prints. Thus, for example, the number of prints of the label 110 is counted after the paper roll 100 is set in the wrong insertion detection device 10, and the rotation amount of the winding shaft 54 ​​is determined based on the number of prints.

[0059] Fig. 9 : is a diagram showing an example of relational data between the number of prints and the return amount according to the first embodiment. The error insertion detection device 10 stores such relational data in the storage unit 20, and obtains the "return amount (step length)" by searching for "number of prints (less than)" using the counted number of prints as a search key. Fig. 9 In the example of , the unit of "number of prints (less than)" is represented by "less than". For example, when the number of prints is 300 sheets, the "return amount (step length)" corresponding to the "number of prints (less than)" of (less than) 500 is obtained. The "return amount (step length)" represents the movement amount of the paper roll 100 in the conveying path. However, the "return amount (step length)" may also be another amount, such as the rotation angle of the take-up shaft 54. In this way, by storing the relationship between the number of prints and the movement amount of the paper roll 100 or the rotation angle of the take-up shaft 54 ​​in the storage unit 20 as data, the rotation amount of the take-up shaft 54 ​​can be determined according to the number of prints.

[0060] Fig. 9 The relational data in is merely an example, and the granularity of "number of prints (less than)" can be finer, or the number of prints can be set to a data format representing a range such as 10 sheets or less, 11 sheets to 200 sheets, 201 sheets to 500 sheets, 501 sheets or more.

[0061] [Processing flow]

[0062] Next, the error insertion detection process performed by the error insertion detection device 10 according to the first embodiment will be described along the processing flow. Fig.10 is a flowchart showing the flow of the error insertion detection process according to the first embodiment.

[0063] First, if Fig.10As shown, the erroneous insertion detection device 10 performs a reset operation (step S101). For example, the reset operation is an initialization or reset process of various types of setting information performed when the paper roll 100 is completely set in the erroneous insertion detection device 10, when the feeding test of the erroneous insertion detection device 10 is completed, etc. In addition, through the reset operation, the label 110 attached to the paper roll 100 is also controlled to move to a suitable position. For example, the suitable position is between the platen roller 51 and the thermal head 52 or in front of the platen roller 51 and the thermal head 52, so that information is properly printed on the label 110.

[0064] When the reset operation is performed, the error insertion detection device 10 then refers to the setting information in the storage unit 20, and determines whether an RFID unit (such as the RFID reader / writer 50) is installed in the error insertion detection device 10 (step S102). When the RFID unit is not installed (No at step S102), the RFID tag 115 is neither written nor error insertion occurs at the first position. Therefore, Fig.10 The error insertion detection process shown in is completed.

[0065] On the other hand, when the RFID unit is installed (Yes at step S102), the erroneous insertion detection device 10 refers to the setting information in the storage unit 20, and determines whether the RFID identifier 115 is set in the erroneous insertion detection device 10 (step S103). When the paper roll 100 to which the label 110 with the RFID identifier 115 is attached is set in the erroneous insertion detection device 10, the RFID identifier 115 is set in the erroneous insertion detection device 10. If the RFID identifier 115 is not set (No at step S103), the RFID identifier 115 is neither written nor erroneous insertion occurs. Therefore, Fig.10 The error insertion detection process shown in is completed.

[0066] On the other hand, when the RFID tag 115 is set (Yes at step S103), the error insertion detection device 10 refers to the storage unit 20 and determines whether the detection flag is on or off (step S104). If the detection flag is off (step S104: No), the error insertion of the RFID tag 115 has not occurred. Therefore, Fig.10 The error insertion detection process shown in FIG. 1 is completed. The processing order of each determination process from step S102 to step S104 does not need to be the same as Fig.10 The processing shown in is in the same order and can be executed in parallel.

[0067] On the other hand, if the detection flag is on (Yes at step S104), the wrong insertion detection device 10 rotates the take-up shaft 54 ​​in the reverse direction by a second amount (step S105). In this example, the second amount is Figure 5The rotation amount shown is for keeping the normal tag 110 - 1 outside the read / write range 80 , and is, for example, the rotation amount of the take-up shaft 54 ​​for moving the take-up shaft 54 ​​by approximately several tags 110 .

[0068] Next, the erroneous insertion detection device 10 starts reading the RFID tag 115 (step S106).

[0069] Next, the erroneous insertion detection device 10 rotates the take-up shaft 54 ​​by a first amount in the reverse direction (step S107). Therefore, the erroneous insertion detection device 10 can read the RFID tag 115 on the paper roll 100 moving along the conveying path in the reverse direction. Steps S106 and S107 may also be reversed, and the reading of the RFID tag 115 may be started after the take-up shaft 54 ​​is rotated. In addition, in order to improve the accuracy of reading the RFID tag 115, the erroneous insertion detection device 10 may also rotate the take-up shaft 54 ​​while temporarily stopping the take-up shaft 54 ​​or reducing the speed of the take-up shaft 54.

[0070] Next, the erroneous insertion detection device 10 rotates the take-up shaft 54 ​​in the forward direction by a first amount (step S108). This is done to improve the detection rate of erroneous insertion of the RFID tag 115, and reads the RFID tag 115 when the paper roll 100 that has been moved in the reverse direction along the conveying path (at step S107) is moved in the forward direction so that the paper roll 100 returns to the initial position.

[0071] Next, the erroneous insertion detection device 10 completes reading the RFID tag 115 (step S109). If the RFID tag 115 is read only when the take-up shaft 54 ​​rotates in the reverse direction (step S107), steps S108 and S109 may be reversed, and the take-up shaft 54 ​​may rotate in the forward direction after the reading of the RFID tag 115 is completed.

[0072] Next, the error insertion detection device 10 determines whether the RFID tag 115 is successfully read (step S110). When the RFID tag 115 is successfully read (yes at step S110), the error insertion detection device 10 determines that the RFID tag 115 is incorrectly inserted, and notifies the occurrence of the incorrect insertion by outputting a notification sound or the like (step S111). After executing step S111, Fig.10 However, after the erroneously inserted tag 110 - 2 is removed by the user, the erroneous insertion detection process is performed again to determine whether the erroneous insertion of the RFID tag 115 is resolved.

[0073] On the other hand, when the reading of the RFID tag 115 fails (No at step S110), the error insertion detection device 10 determines that the error insertion of the RFID tag 115 has not occurred, and rotates the take-up shaft 54 ​​in the forward direction by a second amount (step S112). This process is performed to allow the normal tag 110-1 that was saved outside the read / write range 80 at step S105 to return to the initial position. In addition, when the reading of the RFID tag 115 fails (No at step S110), the detection flag can be set to off. Therefore, the error insertion detection device 10 determines that the error insertion of the RFID tag 115 has not occurred or has been resolved, and controls so that the error insertion detection process will not be repeated. After executing step S112, Fig.10 The error insertion detection process shown in is completed.

[0074] [Effect]

[0075] As described above, the erroneous insertion detection device 10 performs the process of reading the RFID tag 115 before rotating the winding shaft 54 ​​of the paper roll 100 to which the RFID tag 115 is attached by a fixed amount, and determines the erroneous insertion of the RFID tag 115 based on the reading result.

[0076] In this way, the error insertion detection device 10 can detect the error insertion of the RFID tag 115 by reading the error inserted RFID tag 115 which is not peeled off from the paper roll 100 and is within the read / write range 80 of the RFID tag 115 where the RFID tag 115 should not exist.

[0077] In addition, the erroneous insertion detection device 10 further performs a process of rotating the take-up shaft 54 ​​of the take-up paper roll 100 in the reverse direction by the first amount and rotating the take-up shaft 54 ​​in the forward direction by the first amount. The process of performing reading performed by the erroneous insertion detection device 10 includes a process of performing reading before the rotation of the take-up shaft 54 ​​in at least one of the reverse direction and the forward direction by the first amount is completed.

[0078] In this manner, the erroneous insertion detection device 10 can detect erroneous insertion of the RFID tag 115 by reading the erroneously inserted RFID tag 115 in the read / write range 80 of the RFID tag 115 when rotating the take-up shaft 54 ​​in the reverse direction or the forward direction.

[0079] Furthermore, when determining that erroneous insertion has occurred, the erroneous insertion detection device 10 further performs a process of notifying the occurrence of erroneous insertion.

[0080] Therefore, the erroneous insertion detection device 10 can notify the user of the erroneous insertion of the RFID tag 115 .

[0081] Furthermore, the incorrect insertion detection device 10 further performs a process of rotating the take-up shaft 54 ​​in the reverse direction by a second amount before rotating the take-up shaft 54 ​​in the reverse direction by a first amount.

[0082] Therefore, the erroneous insertion detection device 10 can accurately detect only the erroneously inserted tag 110 - 2 without detecting the normal tag 110 - 1 by keeping the normal tag 110 - 1 outside the read / write range 80 of the RFID tag 115 .

[0083] Furthermore, when it is determined that the erroneous insertion has not occurred, the erroneous insertion detection device 10 further performs a process of rotating the take-up shaft 54 ​​in the forward direction by a second amount.

[0084] Therefore, the erroneous insertion detection device 10 can allow the normal tag 110 - 1 held outside the read / write range 80 of the RFID tag 115 to return to the original position and start a normal operation.

[0085] Furthermore, a process of performing reading by the erroneous insertion detection device 10 is performed in response to determining that the detection flag is on, which is set to on when the paper roll 100 is completely set in the erroneous insertion detection device 10 or when the feeding test of the erroneous insertion detection device 10 is completed, and which is set to off when it is determined based on the reading result that erroneous insertion has not occurred.

[0086] Therefore, the erroneous insertion detection apparatus 10 can detect the erroneous insertion of the RFID tag 115 which tends to occur after the reset operation of the erroneous insertion detection apparatus 10 .

[0087] In addition, the erroneous insertion detection device 10 further performs a process of counting the number of prints of the label 110 on the paper roll 100 and deciding a fixed amount of rotation based on the number of prints.

[0088] Therefore, for example, the erroneous insertion detection device 10 can further accurately determine the rotation amount per one turn of the winding shaft 54 ​​whose diameter gradually increases as the paper roll 100 is wound up.

[0089] Furthermore, at least one of the process of rotating the take-up shaft 54 ​​in the reverse direction by the first amount and the process of rotating the take-up shaft 54 ​​in the forward direction by the first amount performed by the erroneous insertion detection device 10 includes the process of rotating the take-up shaft 54 ​​by the first amount while temporarily stopping the take-up shaft 54.

[0090] Therefore, the error insertion detection device 10 can improve the accuracy of reading the RFID tag 115 .

[0091] In addition, the process of rotating the winding shaft 54 ​​in the reverse direction by a first amount and the process of rotating the winding shaft 54 ​​in the forward direction by a first amount performed by the error insertion detection device 10 include the following process: when the reading of the RFID tag 115 is performed, the rotation speed of the winding shaft 54 ​​is reduced compared to when the reading of the RFID tag 115 is not performed.

[0092] Therefore, the error insertion detection device 10 can improve the accuracy of reading the RFID tag 115 .
