Description

  The present invention relates to a medium reading device that reads information written on the surface of an inserted medium.

  Lottery counters and fiduciary banks that sell winning certificates are generally equipped with a medium reading device for checking whether or not a previously drawn winning certificate is winning. When the medium reading device throws in the winning money voucher, the medium reading device takes in the inputted winning money vouchers one by one, and reads the lottery number, the bar code and the like written on the surface.

  The above flow will be described including the operation of the apparatus. When a reading medium, which is a cash voucher, is inserted into the insertion port of the medium reading device, a photo sensor installed near the insertion port causes a cash voucher. Is detected, and the pick roller that holds the winning certificate with a win, which has been retracted from the transport path, holds it. When the pick roller holds the winning gold voucher, the feeding roller rotates, so that the winning gold voucher is transported to the back of the medium reading device through the transport path. There is an image sensor at the back of the transport path, and the image sensor reads the information written on the surface of the winning certificate.

  In such a medium reading device, if the medium cannot be conveyed on the conveying path at a stable speed, there arises a problem that a read image is distorted when the reading medium is read by the image sensor or the reading medium is jammed on the conveying path. As a means for transporting at a stable speed, conventionally, there is provided a temporary holding section for holding the reading medium once inside the apparatus and then holding it, and the length of the conveying path from the insertion section to the image sensor is completely set. There are measures such as making the reading medium longer than the reading medium so that the reading medium can be taken into the apparatus.

  However, there is a demand for a medium reading device having a design such that a temporary holding section or a transport path having a sufficient length cannot be secured due to a space limitation of an installation place or the like. The reading of information on the reading medium in such a medium reading device is influenced by the timing at which the feeding roller starts feeding the reading medium. For example, if the photo sensor detects the insertion of the reading medium, the pick roller grips the reading medium, and immediately starts conveyance by the conveyance roller, if the hand is still holding the reading medium, a stable speed is achieved. Can not be transported. For such a problem, by presetting the time from when the pick roller holds the medium to when the transport roller starts transport, or by the operator setting an arbitrary time, There has been proposed a medium reading device capable of reading normally (see, for example, Patent Document 1).

[Second Embodiment]
In the second embodiment, a case where the first embodiment is used at a lottery counter or the like will be described more specifically. First, the medium reading device according to the second embodiment will be described with reference to FIGS. FIG. 2 is an external view showing a medium reading device according to the second embodiment. FIG. 3 is a plan view showing the vicinity of the insertion port of the medium reading device according to the second embodiment. FIG. 4 is a plan view showing a state in which a reading medium is inserted in the medium reading device according to the second embodiment.

  The reading device 20 includes a notification speaker 25, a notification LED (Light Emitting Diode) 26, a pick roller 27, a conveyance roller 28, a photo sensor 29, an insertion opening 31, and a conveyance path 32.

  The notification speaker 25 outputs a first notification when the reading medium 41 is inserted as shown in FIG. 4, for example, and a second notification when the conveyance of the reading medium 41 is started. And so on. The notification speaker 25 gives a different sound when the photo sensor 29 detects the reading medium 41 and when the conveyance of the reading medium 41 is started. For example, a sound such as "beep" may be given in the first notification, and a sound like "beep" in the second notification. In addition, in the case of the first notification, it may be a voice such as "A read medium has been detected", and in the case of the second notification, it may be a voice such as "Please release your hand". May be.

  The notification LED 26 lights up at the same timing as the notification speaker 25, the first notification when the reading medium 41 is inserted, and the second notification when the conveyance of the reading medium 41 is started is detected by the photosensor 29. And light up. The notification LED 26 lights the upper LED in FIG. 2 in the case of the first notification and lights the lower LED in the case of the second notification. For example, the upper LED side may be labeled with "detected", and the lower LED side may be labeled with "release your hand".

  When the reading medium 41 is inserted, the pick roller 27 holds the reading medium 41 from above and below on the transport path 32 as shown in FIG. After the reading medium 41 is nipped by the pick roller 27, the conveying roller 28 conveys the reading medium 41 on the conveying path by rotating.

  The photosensors 29 are installed at two places. First, near the insertion opening 31, the photosensor 29 detects that the installed reading medium 41 has been inserted into the medium reading device 20 through the insertion opening 31. The second one is installed near the image sensor included in the capturing device 24 described later on the transport path 32, and detects whether a jam error described below has occurred.

  3 and 4 are plan views of the medium reading device 20 as viewed from above. The lower side of the drawing is the insertion port 31 side into which the reading medium 41 is inserted, and the reading medium 41 is inserted from the lower side. It is conveyed upward by the conveying roller 28.

  Next, a hardware configuration example of the medium reading device 20 will be described with reference to FIGS. FIG. 5 is a diagram illustrating a hardware configuration example of the medium reading device according to the second embodiment. FIG. 6 is a table of setting value information stored in the medium reading device according to the second embodiment. FIG. 7 is a table of definition value information stored in the medium reading device according to the second embodiment.

  The medium reading device 20 includes a control unit 21, a display 22, a keyboard 23, a capturing device 24, a notification speaker 25, a notification LED 26, a pick roller 27, a conveyance roller 28, and a photo sensor 29.

  The control unit 21 is entirely controlled by a CPU (Central Processing Unit) 21a. A RAM (Random Access Memory) 21b and a plurality of peripheral devices are connected to the CPU 21a via a bus 21g. The RAM 21b is used as a main storage device of the control unit 21. The RAM 21b stores an OS (Operating System) program to be executed by the CPU 21a and a control application program. Further, the RAM 21b stores various data necessary for the processing by the CPU 21a.

The various data necessary for the processing are set value information 101 as shown in FIG. 6 and definition value information 102 as shown in FIG.
The set value information 101 has information on an operator ID, a first set time, and a second set time.

  The operator ID is identification information uniquely given to the user of the medium reading device 20. The operator ID is read by the medium reading device 20 by reading an ID card or inputting from the keyboard 23.

  The first set time is between the first notification and the second notification, and after the reading medium 41 is detected by the photo sensor 29, the notification speaker 25 or the notification LED 26 starts the conveyance of the reading medium 41. It is the time until the notification. The first set time is stored for each operator ID in accordance with the habits and characteristics of each operator depending on the operator ID.

  In the second set time, the reading medium 41 is actually nipped by the pick roller 27 after the start of the conveyance by the conveying roller 28 is notified by the notification speaker 25 or the notification LED 26, and the reading medium 41 is conveyed by the conveying roller. It is the time until 28 starts to rotate. Similarly to the first set time, the second set time is also saved for each operator ID in accordance with the operator's ID and characteristics according to the operator ID.

  The definition value information 102 has fields of type, details, and value. The type field has items of correction value, minimum definition time, maximum definition time, initial value, and abnormality detection time. The correction value has a first correction value, a second correction value, and a third correction value. The correction value is a numerical value for correcting the first set time or the second set time when the medium reading device 20 fails to read the reading medium 41.

  The minimum definition time has a first minimum definition time and a second minimum definition time. The minimum definition time is the minimum value of the first set time and the second set time that are corrected by the correction value. The maximum definition time has a second maximum definition time, and the first maximum definition time may be added if necessary. Further, the maximum definition time is the maximum value of the second set time corrected by the correction value.

  The initial value has an initial first set value and an initial second set value. Further, the initial value is the initial first set value that is read at the first set time when the user having the corresponding operator ID uses the medium reading device 20 for the first time, and is read at the second set time. Is the initial second set value. This is because the medium reading device 20 of the present case is used while correcting the first set time and the second set time, and there is no data at the first use.

  The abnormality detection time has a first abnormality detection time and a second abnormality detection time. Further, the abnormality detection time is used when the medium reading device 20 detects pulling out of the reading medium 41, and is used to determine whether or not the detection is normal. Such an abnormality detection time is used, for example, as a determination value for determining as an error when the extraction of the reading medium 41 is detected and the time until the detection is too short for normal extraction. It

  Peripheral devices connected to the bus 21g include an HDD (Hard Disk Drive) 21c, a communication interface 21d, a graphic controller 21e, and an input / output interface 21f. The HDD 21c is used as an auxiliary storage device of the control unit 21. An OS program and an application program are stored in the HDD 21c. The HDD 21c also stores set value information 101 and definition value information 102, which are various data necessary for the processing by the CPU 21a. As the auxiliary storage device, another type of non-volatile storage device such as SSD (Solid State Drive) can also be used.

  The display 22 is connected to the graphic control unit 21e. The graphic control unit 21e causes the display 22 to display an image being processed according to an instruction from the CPU 21a. Such a display 22 may be a small panel capable of displaying set values for maintenance and error information.

  A keyboard 23 is connected to the input / output interface 21f. The input / output interface 21f sends a signal sent from the keyboard 23 to the CPU 21a via the bus 21g.

  The keyboard 23 accepts input of characters and the like, but may be in a mode in which it is connected only during maintenance or a mode such as a simple keypad. The capture device 24 includes an image sensor that reads information on the read medium 41. The description of the notification speaker 25, the notification LED 26, the pick roller 27, the conveyance roller 28, and the photosensor 29 is omitted because it is the same as that described above.

  The communication interface 21d is connected to the network 70 and transmits / receives data to / from a host control system. With the above hardware configuration, the processing function of the medium reading device 20 of the present embodiment can be realized.

  Next, the medium reading process executed by the medium reading device 20 having the above configuration will be described with reference to FIG. FIG. 8 is a flowchart of the medium reading process executed by the medium reading device according to the second embodiment.

  The medium reading process represents the entire process executed by the medium reading device 20, and includes a setting value information reading process, an insertion notifying process, a conveyance notifying process, and a conveyance time-out process. After the normal end, the process returns to the medium reading process again. However, when the setting value information 101 is updated during each process, the process returns to the inside of the setting value information reading process. At the start of the medium reading process, the operator is operating the medium reading device 20 to read the reading medium 41.

[Step S01] The medium reading device 20 executes a setting value information reading process. Details will be described later.
[Step S02] The reading medium 41 is inserted into the medium reading device 20. Further, the control unit 21 of the medium reading device 20 reads the setting value by the setting value information reading process described later before step S01.

[Step S03] The medium reading device 20 executes insertion detection processing. Details will be described later.
[Step S04] The medium reading device 20 executes a conveyance notification process. Details will be described later.
[Step S05] The control unit 21 of the medium reading device 20 causes the pick roller 27 to hold the reading medium 41.

[Step S06] The control unit 21 of the medium reading device 20 starts the carrying roller 28.
[Step S07] The control unit 21 of the medium reading device 20 determines whether a jam error has occurred. The jam error generally means a failure when the reading medium is not read by the reading device.

  The control unit 21 of the medium reading device 20 determines that there is a jam error because the photo sensor 29 installed on the image sensor side on the conveyance path 32 does not detect the reading medium 41 for a certain period of time. When the control unit 21 of the medium reading device 20 determines that there is a jam error, the next process proceeds to step S08. If the control unit 21 of the medium reading device 20 determines that there is no jam error, the process proceeds to step S09.

[Step S08] The medium reading device 20 executes a conveyance time-out process. Details will be described later.
[Step S09] The control unit 21 of the medium reading device 20 causes the take-in device 24 to read the reading medium 41. Information is written on the surface of the reading medium 41, and the capturing device 24 reads the information by an optical method using, for example, an image sensor.

  [Step S10] The control unit 21 of the medium reading device 20 initializes the processing regarding the reading processing. With the above processing, the entire processing executed by the medium reading device 20 is realized.

  Next, the setting value information reading process executed by the medium reading device 20 having the above configuration will be described with reference to FIG. FIG. 9 is a flowchart of the setting value information reading process executed by the medium reading device according to the second embodiment.

  The setting value information reading process represents a process of reading the setting information used by the medium reading device 20. At the start of the setting value information reading process, the medium reading process is step S01, and the operator is operating the medium reading device 20 to read the reading medium 41.

  [Step S11] The control unit 21 of the medium reading device 20 receives the input of the operator ID from the keyboard 23. The input of the operator ID may be received by the medium reading device 20 by reading an ID card or the like.

[Step S12] The control unit 21 of the medium reading device 20 refers to the setting value information 101.
[Step S13] The control unit 21 of the medium reading device 20 determines whether the setting value information 101 includes setting value information corresponding to the accepted operator ID. For example, in the setting value information 101 of FIG. 6, when the received operator ID is “00002”, the control unit 21 of the medium reading device 20 determines that the setting value information 101 exists.

  When the control unit 21 of the medium reading device 20 determines that the setting value information 101 exists, the next process proceeds to step S15. When the control unit 21 of the medium reading device 20 determines that the setting value information 101 does not exist, the next process proceeds to step S14.

  [Step S14] The control unit 21 of the medium reading device 20 reads the initial value of the set value information 101 at the first set time and the second set time. At this time, the initial first set value is read in the first set time, and the initial second set value is read in the second set time. The initial value is the initial first set value that is read at the first set time when the user with the corresponding operator ID uses the medium reading device 20 for the first time, and is read at the second set time. This is the initial second set value.

  [Step S15] The control unit 21 of the medium reading device 20 reads the set value information 101 at the first set time and the second set time. With the above processing, the setting value information reading processing executed by the medium reading device 20 is realized.

  Next, the insertion notification process executed by the medium reading device 20 having the above configuration will be described with reference to FIG. FIG. 10 is a flowchart of the insertion detection process executed by the medium reading device according to the second embodiment.

  The insertion notification process represents a process of transitioning to the conveyance notification time improvement process when the medium reading device 20 detects the insertion of the reading medium 41, notifies the insertion, and detects the pulling out of the reading medium 41. Further, at the start of the insertion detection process, the state is step S03 of the medium reading process.

  [Step S21] The control unit 21 of the medium reading device 20 determines whether or not the photo sensor 29 optically detects the insertion of the reading medium 41. The photo sensor 29 detects the reading medium 41 when the reading medium 41 is inserted and the reading medium 41 passes over the photo sensor 29 in the transport path.

  When the control unit 21 of the medium reading device 20 determines that the reading medium 41 is detected, the next process proceeds to step S22. Further, the control unit 21 of the medium reading device 20 waits for detection of the reading medium 41.

  [Step S22] The control unit 21 of the medium reading device 20 turns on the notification LED 26. The notification LED 26 lights up to notify that the reading medium 41 is detected. Further, the notification LED 26 is turned on during the reading process for the first notification, and the notification LED 26 on the left side of the display “Detected” shown in FIG. 2 is turned on.

  [Step S23] The control unit 21 of the medium reading device 20 causes the notification speaker 25 to output a notification sound. The notification speaker 25 notifies the detection of the reading medium 41 by the notification voice, and this notification corresponds to the first notification for the first time during the reading process. It should be noted that the first notification may be performed by only one of the notification LED 26 and the notification speaker 25.

[Step S24] The control unit 21 of the medium reading device 20 starts measuring the first waiting time.
[Step S25] The control unit 21 of the medium reading device 20 determines whether or not the photo sensor 29 detects pulling out of the reading medium 41. The control unit 21 of the medium reading device 20 detects pulling out of the reading medium 41, for example, when the photo sensor 29 once detects the reading medium 41 and then stops detecting it.

  When the control unit 21 of the medium reading device 20 determines that the pulling out of the reading medium 41 is detected, the next process is advanced to the transport notification time improving process for improving the first set time so that the pulling out does not occur. If the control unit 21 of the medium reading device 20 determines that the pulling out of the reading medium 41 is not detected, the next process proceeds to step S26.

  [Step S26] The control unit 21 of the medium reading device 20 determines whether or not the first standby time exceeds the first set time. The fact that the first standby time exceeds the first set time means that after the reading medium 41 is detected by the photosensor 29, the notification speaker 25 or the notification LED 26 notifies the start of the conveyance by the conveyance roller 28. It indicates that the time has elapsed until the second notification.

  When the control unit 21 of the medium reading device 20 determines that the first standby time exceeds the first set time, the next process proceeds to step S27. If the control unit 21 of the medium reading device 20 determines that the first standby time has not exceeded the first set time, the next process returns to step S25.

  [Step S27] The control unit 21 of the medium reading device 20 ends the measurement of the first waiting time. The insertion notification processing executed by the medium reading device 20 is realized by the above processing.

  Next, the conveyance notification time improving process executed by the medium reading device 20 having the above configuration will be described with reference to FIG. FIG. 11 is a flowchart of the transport notification time improvement process executed by the medium reading device according to the second embodiment.

  The conveyance notification time improving process is a process of correcting the first set time when the medium reading device 20 detects the pulling out of the reading medium 41, and improving so that the pulling out does not occur after the next time. At the start of the transport notification time improvement process, the state is after step S25 of the insertion notification process.

[Step S31] The control unit 21 of the medium reading device 20 ends the measurement of the first waiting time.
[Step S32] The control unit 21 of the medium reading device 20 turns off the notification LED 26.

  [Step S33] The control unit 21 of the medium reading device 20 determines whether the first standby time is shorter than the first abnormality detection time. The first waiting time is the time from when the control unit 21 of the medium reading device 20 detects the insertion of the reading medium 41 to step S31.

  The first abnormality detection time is used when the medium reading device 20 detects that the reading medium 41 is pulled out, and is used to determine whether or not the detection is normal. Further, the first abnormality detection time is determined on the basis of the time considered to be too short as the first waiting time. For example, the first standby time when the medium is slid in and out when the medium is inserted becomes equal to or less than the first abnormality detection time, and the transport notification time improvement process is not executed.

  When the control unit 21 of the medium reading device 20 determines that the first standby time is shorter than the first abnormality detection time, the next process proceeds to step S12. If the control unit 21 of the medium reading device 20 does not determine that the first standby time is shorter than the first abnormality detection time, the next process proceeds to step S34.

  [Step S34] The control unit 21 of the medium reading device 20 updates the first set time with a value obtained by subtracting the first correction time from the first standby time. The first correction time is a numerical value for correcting the first set time when the medium reading device 20 fails to read the reading medium 41. For example, the control unit 21 of the medium reading device 20 determines that the first waiting time is long when the operator pulls out the reading medium 41 from the medium reading device 20 during the first waiting time. Therefore, the first waiting time is set shorter.

  [Step S35] The control unit 21 of the medium reading device 20 determines whether or not the updated first set time is shorter than the first minimum defined time. The first minimum definition time is the minimum value of the first set time corrected by the correction value. For example, the first minimum definition time is set to a minimum value as an empirical rule because no operator can set the first standby time to be 0 or less.

  When the control unit 21 of the medium reading device 20 determines that the first set time is shorter than the first minimum defined time, the next process proceeds to step S36. When the control unit 21 of the medium reading device 20 determines that the first set time is not shorter than the first minimum defined time, the next process proceeds to step S12.

[Step S36] The control unit 21 of the medium reading device 20 updates the first set time with the first minimum defined time.
[Step S37] The control unit 21 of the medium reading device 20 causes the HDD 21c to update the set value information at the updated first set time. By the above-described processing, the transport notification time improvement processing executed by the medium reading device 20 is realized.

  Next, the conveyance notification process executed by the medium reading device 20 having the above configuration will be described with reference to FIG. FIG. 12 is a flowchart of the transport notification process executed by the medium reading device according to the second embodiment.

  The conveyance notification process notifies the conveyance of the reading medium 41 after the first set time elapses, starts measuring the second waiting time, and determines until the second waiting time exceeds the second setting time. This is a process, and when pulling out is detected, the process proceeds to the conveyance standby time improvement process. At the start of the transport notification process, the state is step S04 of the medium reading process.

  [Step S41] The control unit 21 of the medium reading device 20 turns on the notification LED 26. Illumination of the notification LED 26 is a second notification that notifies the start of conveyance of the reading medium 41. The notification LED 26 is turned on for the second time during the reading process, and the notification LED 26 on the left side of the display "Please release your hand" shown in FIG. 2 is turned on.

  [Step S42] The control unit 21 of the medium reading device 20 causes the notification speaker 25 to output a notification sound. The output of this notification voice is the second notification. Further, for example, the second notification may be either the lighting of the notification LED 26 or the output of sound by the notification speaker 25.

[Step S43] The control unit 21 of the medium reading device 20 starts measuring the second standby time.
[Step S44] The control unit 21 of the medium reading device 20 determines whether or not the photo sensor 29 detects pulling out of the reading medium 41. When the control unit 21 of the medium reading device 20 determines that the pulling out of the reading medium 41 is detected, the next process is advanced to the conveyance standby time improvement process. When the control unit 21 of the medium reading device 20 determines that the pulling out of the reading medium 41 is not detected, the next process proceeds to step S45.

  [Step S45] The control unit 21 of the medium reading device 20 determines whether or not the second standby time exceeds the second set time. The second waiting time is the time from step S43 to step S45. However, step S43, step S41, and step S42 are almost simultaneous.

  When the control unit 21 of the medium reading device 20 determines that the second standby time exceeds the second set time, the next process proceeds to step S46. When the control unit 21 of the medium reading device 20 determines that the second standby time does not exceed the second set time, the next process returns to step S44.

  [Step S46] The control unit 21 of the medium reading device 20 ends the measurement of the second standby time. By the above processing, the conveyance notification processing executed by the medium reading device 20 is realized.

  Next, the conveyance standby time improvement process executed by the medium reading device 20 having the above configuration will be described with reference to FIG. FIG. 13 is a flowchart of the conveyance standby time improvement process executed by the medium reading device according to the second embodiment.

  The conveyance standby time improving process is a process of correcting the second set time when the medium reading device 20 detects the pulling out of the reading medium 41, and improving so that the pulling out does not occur after the next time. At the start of the transport standby time improvement process, the state is that after the pulling out of the reading medium 41 is detected in step S44 of the transport notification process.

[Step S51] The control unit 21 of the medium reading device 20 ends the measurement of the second standby time.
[Step S52] The control unit 21 of the medium reading device 20 turns off the notification LED 26.

  [Step S53] The control unit 21 of the medium reading device 20 determines whether the second standby time is shorter than the second abnormality detection time. The second abnormality detection time is used when the medium reading device 20 detects that the reading medium 41 is pulled out, and is used to determine whether or not the detection is normal. Further, the second abnormality detection time is determined based on the time which is considered to be too short as the second waiting time. For example, when the operator pulls out the reading medium 41 immediately after lighting the notification LED 26 for the first time and then for the second time, it does not mean that the conveyance of the reading medium 41 is slow because the second waiting time is long. This is because it is considered that the second lighting of the notification LED 26 is delayed.

  When the control unit 21 of the medium reading device 20 determines that the second standby time is shorter than the second abnormality detection time, the next process proceeds to step S54. If the control unit 21 of the medium reading device 20 does not determine that the second standby time is shorter than the second abnormality detection time, the next process proceeds to step S55.

[Step S54] The control unit 21 of the medium reading device 20 updates the first set time with a value obtained by subtracting the first correction time from the first standby time.
[Step S55] The control unit 21 of the medium reading device 20 updates the second set time with a value obtained by subtracting the second correction time from the second standby time. The second correction time is a numerical value for correcting the second set time when the medium reading device 20 fails to read the reading medium 41.

  For example, the control unit 21 of the medium reading device 20 determines that the second waiting time is long when the operator pulls out the reading medium 41 from the medium reading device 20 during the second waiting time. Therefore, the second waiting time is set shorter.

  [Step S56] The control unit 21 of the medium reading device 20 determines whether the first set time is shorter than the first minimum defined time. When the control unit 21 of the medium reading device 20 determines that the first set time is shorter than the first minimum defined time, the next process proceeds to step S58. If the control unit 21 of the medium reading device 20 determines that the first set time is not shorter than the first minimum defined time, the next process proceeds to step S60.

  [Step S57] The control unit 21 of the medium reading device 20 determines whether the second set time is shorter than the second minimum defined time. The second minimum definition time is the minimum value of the second set time corrected by the correction value. For example, the second minimum defined time is set to the minimum value as an empirical rule because no operator can set the second standby time to be 0 or less.

  When the control unit 21 of the medium reading device 20 determines that the second set time is shorter than the second minimum defined time, the next process proceeds to step S59. If the control unit 21 of the medium reading device 20 determines that the second set time is not shorter than the second minimum defined time, the next process proceeds to step S60.

[Step S58] The control unit 21 of the medium reading device 20 updates the first set time with the first minimum defined time.
[Step S59] The control unit 21 of the medium reading device 20 updates the second set time with the second minimum defined time.

  [Step S60] The control unit 21 of the medium reading device 20 causes the HDD 21c to update the first set time and the second set time of the set value information. Here, the first set time used for updating the set value information is the updated first set time updated in steps S54, S56, and S58. Further, the second set time used for updating the setting information here is step S55, step S57, and the updated second set time updated in step S59. By the above-described processing, the conveyance standby time improvement processing executed by the medium reading device 20 is realized.

  Next, the transport time-out process executed by the medium reading device 20 having the above configuration will be described with reference to FIG. FIG. 14 is a flowchart of the transport time-out process executed by the medium reading device according to the second embodiment.

  The conveyance time-out process is a process in which the medium reading device 20 determines whether or not a jam error has occurred during the conveyance of the reading medium 41. If a jam error occurs, the second set time is corrected if it is too short, It is a process to improve so that a jam error does not occur after that. Further, at the start of the conveyance standby time improvement process, the state is step S08 of the medium reading process.

  Here, the jam error refers to a state in which the reading medium 41 is jammed on the conveyance path and cannot be conveyed by the conveyance roller 28. The jam error is resolved by opening and closing the medium reading device 20 and taking out the reading medium 41.

[Step S61] The control unit 21 of the medium reading device 20 turns off the notification LED 26.
[Step S62] The control unit 21 of the medium reading device 20 updates the second set time with a value obtained by adding the third correction time to the second standby time. The third correction time is a numerical value for correcting the second set time when the medium reading device 20 detects the time-out of conveyance of the reading medium 41. For example, the third correction time is a correction time for extending the second set time when the reading medium 41 is conveyed quickly after the second lighting of the notification LED 26 and a jam error occurs.

  [Step S63] The control unit 21 of the medium reading device 20 determines whether the second set time is longer than the second maximum defined time. The second maximum definition time is the maximum value of the second set time corrected by the third correction time. For example, if the second set time is extremely long, the start of conveyance of the reading medium 41 will be extremely delayed, and thus the second maximum defined time will be the second maximum of the notification LED 26 even for an operator unfamiliar with the operation. The time period after which it is assumed that the reading medium 41 can be released after the light is turned on is set according to the rule of thumb.

  When the control unit 21 of the medium reading device 20 determines that the second set time is longer than the second maximum defined time, the next process proceeds to step S64. If the control unit 21 of the medium reading device 20 determines that the second set time is not longer than the second maximum defined time, the process proceeds to step S65.

[Step S64] The control unit 21 of the medium reading device 20 updates the second set time with the second maximum defined time.
[Step S65] The controller 21 of the medium reading device 20 stops the carrying roller 28.

[Step S66] The control unit 21 of the medium reading device 20 causes the display 22 to display a jam error screen (not shown).
[Step S67] The control unit 21 of the medium reading device 20 determines whether or not the jam error is removed. When the control unit 21 of the medium reading device 20 determines that the jam error has been removed, the next process proceeds to step S68. Further, the control unit 21 of the medium reading device 20 waits until the jam error is removed.

  [Step S68] The control unit 21 of the medium reading device 20 causes the HDD 21c to update the set value information with the second set time updated in steps S62 and S64. By the above-described processing, the transport timeout processing executed by the medium reading device 20 is realized.

  The medium reading device 20 holds the first set time and the second set time for each operator ID included in the set value information 101, and uses the read operator ID before the reading process of the reading medium 41. The corresponding set value information 101 is read. When the medium reading device 20 detects that the reading medium 41 is inserted, the notification speaker 25 and the notification LED 26 make a first notification that the insertion of the reading medium 41 has been detected. At the same time, the measurement of the first waiting time is started.

After that, when the reading process fails due to pulling out of the reading medium 41, the first correction value information is used to improve the first set time, and the reading medium 41 is waited for insertion again.
Next, the medium reading device 20 conveys the reading medium 41 by the notifying speaker 25 and the notifying LED 26 included in the notifying means when the reading medium 41 is not pulled out after the first set time ends. Is secondly notified. At the same time, the measurement of the second waiting time is started.

After that, when the reading process fails due to the pulling out of the reading medium 41, the second correction value information is used to improve the second set time, and the reading medium 41 is waited for insertion again.
Finally, the medium reading device 20 sandwiches the reading medium 41 with pick rollers, starts the conveyance rollers, and when the conveyance does not fail, reads the reading medium 41 and initializes the reading process. On the other hand, when the conveyance has failed, the second set time is corrected by the third correction value information, and the reading medium 41 is waited for insertion again.

  Such a medium reading device 20 clarifies the timing of releasing the hand from the reading medium 41 by first notifying the detection of the insertion of the reading medium 41 and second notifying the start of conveyance, and setting the first set time as , And the second set time can be improved to reduce reading errors.

In addition, the medium reading device 20 as described above can greatly reduce the reading error by improving the first set time and the second set time as the actual conveyance fails.
Further, since the medium reading device 20 improves the set time for each reading error, the operator does not have to set the set time by himself, and the setting can be performed with higher accuracy than when the user manually sets the set time. Time can be utilized and reading errors can be reduced. In addition, by saving such set time for each operator and utilizing the set time according to the habits and characteristics of the operator, reading errors can be reduced.
