A change point storage unit 156 and a conveyance control unit 157 are provided.

  The inspection start instruction unit 151 outputs a start instruction signal for instructing start of inspection for conveyance abnormality. Various methods can be applied to the inspection start instruction method. For example, when an inspection is started by an operation of a maintenance person or the like, a method of wirelessly transmitting a start instruction signal to the inspection medium 19 can be applied. Further, the receiver 17 and the receiver 18 can also receive a start instruction signal by radio, and start reception by receiving the start instruction signal.

Is used to determine the position of the medium that travels, and to identify an abnormal conveyance location.

(A-2) Operation of the First Embodiment Next, the operation of the conveyance abnormality detection process in the automatic transaction apparatus 100 of the first embodiment will be described with reference to the drawings.

  For example, when inspecting a conveyance abnormality, a maintenance person presses an inspection start button or performs a remote operation, and an inspection operation start instruction signal is given to the conveyance abnormality detection unit 15. In the conveyance abnormality detection unit 15, when an inspection operation start instruction signal is given, the inspection start instruction unit 151 wirelessly transmits the start instruction signal.

  The start instruction signal from the conveyance abnormality detection unit 15 is received by the transmitter 191 of the inspection medium 19. When the transmitter 191 receives the start instruction signal, the transmission start / stop unit 1911a starts radio wave transmission. At the same time, the receiver 17 and the receiver 18 also receive the start instruction signal and start radio wave reception.

  In the conveyance abnormality detection unit 15, the conveyance control unit 157 confirms that the receiver 17 and the receiver 18 can normally receive radio waves from the transmitter 191 of the inspection medium 19. When it is confirmed that the receiver 17 and the receiver 18 can normally receive radio waves, the transport control unit 157 starts transporting the inspection medium 19 stored in the inspection medium storage unit 16.

  Since the transmitter 191 of the inspection medium 19 transmits radio waves, the inspection medium 19 is conveyed while transmitting radio waves. When the conveyance of the inspection medium 19 is completed, the inspection medium 19 is returned to and stored in the inspection medium 19.

  Since the inspection medium 19 is transported, the distance between the transmitter 191 and the receiver 17 and the receiver 18 changes, so that the radio wave reception intensity at the receiver 17 and the receiver 18 also changes. The reception intensity data of radio waves at the receiver 17 and the receiver 18 is given to the conveyance abnormality detection unit 15.

  In the conveyance abnormality detection unit 15, the conveyance abnormality determination unit 152 receives the reception intensity registration transition data stored in the reception intensity registration transition data storage unit 154 and the reception intensity obtained by the receiver 17 and the receiver 18 in this inspection. Compare with transition data.

  That is, the conveyance abnormality detection unit 15 compares the data patterns of temporal changes between the reception intensity transition data at the time of inspection and the reception intensity registration transition data, and detects the conveyance abnormality and its location.

  7A and 7B are time charts of sensor data of the conveyance sensor C and the conveyance sensor D, and FIG. 7C is a time chart showing a time change of radio wave reception intensity in the receiver 18. It is. In FIG. 7C, a dotted line is reception intensity registration transition data in the receiver 18 during normal operation, and a solid line is reception intensity transition data in the receiver 18 during inspection. Here, the case where the reception intensity transition data in the receiver 18 is used is illustrated, but similar data can be obtained also when the reception intensity transition data of other receivers 17 is used.

  As shown in FIG. 1, the receiver 18 is disposed in the vicinity of the recognition unit 12 and between the conveyance sensor C and the conveyance sensor D and relatively close to the conveyance sensor C. Therefore, as shown in FIG. 7C, the reception intensity at the receiver 18 is relatively weak at the beginning, but gradually increases with time. Then, when the transmitter 191 and the receiver 18 are closest, the reception intensity becomes the highest, and thereafter, the reception intensity gradually decreases.

  The conveyance abnormality determination unit 152 compares the reception intensity registration transition data registered in advance with the reception intensity transition data at the time of this inspection, and the reception intensity transition data at the time of inspection changes differently from the reception intensity registration transition data. It is determined that there is a conveyance error. That is, the conveyance abnormality determination unit 152 determines that a conveyance abnormality has occurred when a deviation from the data pattern of the received intensity registration transition data has occurred, and determines that the position of the deviation is an abnormal location.

  For example, in the case of FIG. 7C, the reception strength transition data at the time of inspection is different from the reception strength registration transition data at time t1. In other words, here, the conveyance abnormality determination unit 152 detects that there is slack in conveyance (S11).

  Although not shown in FIG. 7C, even if the sensor change point time between the transport sensor C and the transport sensor D is the same, the transport speed of the inspection medium 19 increases or decreases during that time. It may become. However, by comparing the data patterns, the conveyance abnormality determination unit 152 can also detect a change in the conveyance speed of the inspection medium 19 between the sensor change points.

  Next, the conveyance abnormality location identification unit 153 identifies the location of the conveyance abnormality based on the determination result of the conveyance abnormality determination unit 152 and the sensor data of the conveyance sensor.

  For example, in FIG. 7A and FIG. 7C, the conveyance abnormality point specifying unit 153 is based on the time t1 detected by the conveyance abnormality determination unit 152 and the change point t2 of the conveyance sensor C from ON to OFF. Then, the point moved from the change point t2 by the time (t1-t2) is specified as an abnormal location (S12).

  At this time, for example, if the conveyance speed of the inspection medium 19 is set in advance, the distance can be obtained based on the conveyance speed of the inspection medium 19 and the movement time. Therefore, the position obtained by adding the distance obtained from the position of the transport sensor C can be specified as an abnormal location.

  In FIG. 7, an example of using the ON → OFF conversion point of the conveyance sensor C closest to the conveyance abnormality detection time t1 is illustrated in order to obtain an accurate conveyance abnormality position. However, the present invention is not limited to this. It is not a thing. In addition, a conversion point of the conveyance sensor D from OFF to ON or a change point of another conveyance sensor may be used.
