  In addition, in FIG. 5, the some banknote passage detection sensor 14, the power transmission drive gear 15D-4a, 15D-4b, and the banknote conveyance drive rollers 16D-2a1, 16D-2a2, 16D-3a1, 16D-3a2, and the like in the fourth embodiment. 16D-4a, 16D-1b, 16D-2b, 16D-3b, 16D-4b, power transmission belts 18D-4a1, 18D-4a2, bill transport belts 19D-2b, 19D-3a1, 19D-3a2, 19D-3b1 , 19D-3b2, 19D-4b1, and 19D-4b2 are merely examples, so long as the substantially V-shaped one-dimensional image sensor 13D is disposed on the conveyance path 7a. An aspect may be sufficient.

  Further, the one-dimensional image sensor 13D is not limited to the arrangement mode shown in FIG. 5, and the bottom portion constituting the V-shape is positioned on the front side in the conveying direction shown in FIG. The arrangement | positioning located in the back side of the conveyance direction shown in FIG. Moreover, banknote conveyance drive roller 16D-2a1-16D-4b may be arrange | positioned above the conveyance path 7a, and a banknote conveyance follower roller (not shown) may be arrange | positioned below the conveyance path 7a.

  Compared with the banknote handling apparatus 1A according to the first embodiment (see FIG. 1), the banknote handling apparatus 1E according to the fifth embodiment replaces the discrimination section 4A with the control section 8A. Instead, the difference is that a control unit 8E is provided. Other points are the same as in the first embodiment.

  FIG. 6 is a side view illustrating an example of a discrimination unit according to the fifth embodiment. FIG. 7 is a side view illustrating an example of a discrimination unit according to the fifth embodiment. As shown in FIG. 6, the discrimination unit 4E built in the banknote handling apparatus 1E according to the fifth embodiment includes an upper unit 4E-1 including a plurality of banknote transport driven rollers 17E, a one-dimensional image sensor 13E, and a plurality of banknote passages. It has a lower unit 4E-2 including a detection sensor 14E, a plurality of power transmission drive gears 15E, a plurality of bill conveyance drive rollers 16E, and a plurality of power transmission belts (not shown). The upper unit 4E-1 has a moving mechanism (not shown) that moves the upper unit 4E-1 itself in a direction in which the vertical height of the transport path 7a is increased. The moving mechanism for moving the upper unit 4E-1 itself may be, for example, an elastic member such as a spring, a latch, a cam mechanism, or the like.

  The discrimination unit 4E includes banknote passage detection sensors 14E on the front and rear sides (upstream and downstream) of the one-dimensional image sensor 13E in the transport direction on the transport path 7a. The controller 8E starts measuring time after the passage of the banknote 2 is detected by the banknote passage detection sensor 14E located upstream of the one-dimensional image sensor 13E in the transport direction of the transport path 7a. And the control part 8E complete | finishes time measurement, when the applicable banknote 2 is detected again by the banknote passage detection sensor 14E located downstream of the one-dimensional image sensor 13E in the conveyance direction of the conveyance path 7a. On the other hand, the control unit 8E continues timing until the corresponding banknote 2 is detected again.

  And the control part 8E determines that the corresponding banknote 2 did not pass the one-dimensional image sensor 13E normally when the predetermined time was measured (timeout) (the paper jam (jam) of the banknote 2 occurred). (See FIG. 6). And control part 8E controls the moving mechanism of upper unit 4E-1 and determines the up-and-down height of conveyance way 7a, when it judges with applicable bill 2 not having passed normally one-dimensional image sensor 13E. By moving the upper unit 4E-1 itself in the direction of enlarging by a predetermined amount, the paper money 2 once jammed by the one-dimensional image sensor 13E can pass through the one-dimensional image sensor 13E (see FIG. 7). . The banknote 2 once jammed by the one-dimensional image sensor 13E is, for example, stored in the temporary storage unit 5 and then transferred to the deposit / withdrawal unit 3 and returned to the depositor for error processing (paper jam processing). .

  The process of controlling the moving mechanism of the upper unit 4E-1 to increase the vertical height of the transport path 7a by a predetermined amount is, for example, the banknote transport drive while increasing the vertical height of the transport path 7a. The pressure at which the banknote 2 is pressed from above and below by the roller 16E and the banknote transport driven roller 17E is reduced from the first pressure to a second pressure smaller than the first pressure, so that the banknote 2 smoothly moves on the transport path 7a. It may be conveyed.

  On the other hand, the control part 8E determines with the corresponding banknote 2 having normally passed the one-dimensional image sensor 13E, when not measuring time-out (timeout) within predetermined time.

[Processing at the time of occurrence of a paper jam in the discrimination section according to the fifth embodiment]
FIG. 8 is a flowchart illustrating an example of a paper jam occurrence process in the discrimination unit according to the fifth embodiment. The paper jam occurrence process in the discrimination unit 4E according to the fifth embodiment is periodically activated and executed by the control unit 8E.

  First, in step S11, the control unit 8E determines whether the upstream banknote passage detection sensor 14E has detected the passage of the banknote 2 or not. The upstream bill passage detection sensor 14E refers to the bill passage detection sensor 14E positioned upstream in the transport direction from the one-dimensional image sensor 13E in the transport path 7a of the discrimination unit 4E. Control part 8E moves processing to Step S12, when upstream banknote passage detection sensor 14E detects passage of banknote 2 (Step S11 Yes), and upstream banknote passage detection sensor 14E has not detected passage of banknote 2. In the case (step S11 No), the process of step S11 is repeated.

  In step S12, the control unit 8E starts time measurement using a timer. Subsequently, in step S13, the control unit 8E determines whether or not the time measurement by the timer has timed out. Control part 8E moves a process to step S14, when the time measurement by a timer times out (step S13 Yes), and moves a process to step S16, when the time measurement by a timer has not timed out (step S13 No).

  In step S14, the control unit 8E controls the moving mechanism of the upper unit 4E-1 including the one-dimensional image sensor 13E and the banknote transport driven roller 17E to move the upper unit 4E-1, and increases the height of the transport path 7a. Enlarge by a predetermined amount. Subsequently, in step S15, the control unit 8E performs a paper jam process as an error process (for example, after the banknote 2 is stored in the temporary storage unit 5, it is transported to the deposit / withdrawal unit 3 and returned to the depositor). .

  Subsequently, in step S <b> 16, the control unit 8 </ b> E determines whether the downstream banknote passage detection sensor 14 </ b> E has detected the passage of the banknote 2. The downstream bill passage detection sensor 14E refers to the bill passage detection sensor 14E that is located downstream of the one-dimensional image sensor 13E in the transport direction in the transport path 7a of the discrimination unit 4E. Control part 8E moves processing to Step S17, when downstream bill passage detection sensor 14E detects passage of bill 2 (Step S16 Yes), and downstream bill passage detection sensor 14E has not detected passage of bill 2. If so (No at step S16), the process proceeds to step S13.

  In step S17, the control unit 8E executes post-processing including processing for clearing the timer through timekeeping in step S12 and returning the height of the conveyance path 7a expanded by the processing in step S14 to the original state. When step S17 ends, the control unit 8E ends the paper jam occurrence process in the discrimination unit 4E.

  According to the fifth embodiment described above, when the banknote 2 does not normally pass through the one-dimensional image sensor 13E on the conveyance path 7a in the discrimination unit 4E and a paper jam (jam) occurs, the one-dimensional image sensor 13E. And the moving mechanism of upper unit 4E-1 including banknote conveyance follower roller 17E is controlled, and upper unit 4E-1 itself is moved to the direction which expands the vertical height of conveyance path 7a. As a result, when a paper jam (jam) occurs in the bill 2, the light emitting unit and the light receiving unit of the one-dimensional image sensor 13E configured by the light emitting unit and the light receiving unit arranged above and below in the conveyance path 7a of the discrimination unit 4E. The banknotes 2 that have increased in interval and have generated a paper jam can be easily passed through the one-dimensional image sensor 13E to quickly eliminate the paper jam, handle the error, and the banknote 2 that follows the banknote 2 that has generated the paper jam. The discrimination process can be continued.

  In addition, you may combine Example 5 with either of Examples 1-4. In addition, the moving mechanism that moves the upper unit 4E-1 itself of the discrimination unit 4E may be controlled by the control unit 8E instead of the control unit 8E.
