A slope surface is formed so as to be longitudinally symmetrical with the slope surface on the rear side of the roller 34D.

  As shown in FIG. 4, slopes 42 Dir and 42 Dil having the same shape are formed at the rear edges of the openings 42 HDir and 42 HDil that project the drive rollers 33 Dir and 33 Dil into the transport path 43 in the lower transport guide 42. ing. Hereinafter, the openings 42HDir and 42HDil are collectively referred to as an inner opening 42HDi as a third opening, and the slopes 42Dir and 42Dil are collectively referred to as an inner slope 42Di. The slopes 42Dir and 42Dil are configured in substantially the same manner as the slopes 42AB, 42BB, and 42CB. As shown in FIG. 6, the depth of the slope 42 </ b> Dil with respect to the conveyance path 43, i.e., from the roller contact portion 46 where the drive roller 33 </ b> D and the driven roller 34 </ b> D contact, to the lower end of the slope surface 42 </ b> DSil of the slope 42 </ b> Dil. The length in the vertical direction is the slope depth DP2.

  As shown in FIG. 4, slopes 42Dor and 42Dol having the same shape are formed on the rear edges of the opening portions 42HDor and 42HDol that allow the driving rollers 33Dor and 33Dol to protrude into the conveyance path 43 in the lower conveyance guide 42, respectively. ing. Hereinafter, the openings 42HDor and 42HDol are collectively referred to as the outer opening 42HDo, the slopes 42Dor and 42Dol are collectively referred to as the outer slope 42Do, the slope surfaces 42DSor and 42DSol are collectively referred to as the outer slope surface 42DSo, and the slope surfaces 42DSir and 42DSil Are collectively referred to as an inner slope surface 42DSi as a third inclined surface. As shown in FIG. 7, the depth of the slope 42 </ b> Dol with respect to the conveyance path 43, i.e., the length in the vertical direction from the roller contact portion 46 to the lower end of the flat slope surface 42 </ b> DSol in the slope 42 </ b> Dol is the slope depth. It is DP3. The outer slope 42Do is formed to be deeper than the inner slope 42Di and the slope 42MB, that is, the slope depth DP3 is larger than the slope depths DP1 and DP2. The outer slope 42Do is formed such that the slope depth DP3 is larger than the roller blade interval CL2 (FIG. 5).

  Between the right end portion of the slope surface 42DSol and the lower conveyance guide surface 42S, an inner wall surface 50i that is a plane extending in the front-rear and up-down directions is formed. In addition, an outer wall surface 50o that is a plane extending in the front-rear and up-down direction and facing the inner wall surface 50i is formed between the left end portion of the slope surface 42DSol and the lower conveyance guide surface 42S. Incidentally, since the distance between the slope surface 42DSol and the drive roller 33Dol (FIG. 7) is set in the same manner as the distance between the slope surfaces 42DSil and 42DSir and the drive roller 33Dil and 33Dir (FIG. 6), the slopes 42Dol and 42Dor The front end (FIG. 7) is located behind the front ends of the slopes 42Dil and 42Dir by the amount lower than the front ends (FIG. 6) of the slopes 42Dil and 42Dir.

[1-5. Operation of discrimination part]
[1-5-1. For normal banknotes]
In this configuration, when performing the deposit process, the discrimination unit 18 (FIG. 3) drives the switching mechanism 36 by an actuator (not shown) based on the control of the control unit 12 and switches the tip so that the tip is directed downward. The bills BL are allowed to pass from the side conveyance path 43C to the identification conveyance path 43A. Next, the discrimination unit 18 transmits driving force to the driving rollers 33A, 33B, 33C, 33D, and 33F, the thickness reference roller 51, and the magnetic gap roller 72 by an actuator (not shown).

  When the bill BL is conveyed from the deposit / withdrawal unit 16 to the discrimination unit 18 via the deposit / withdrawal unit side delivery unit 80B, the discrimination unit 18 first sandwiches the bill between the driving roller 33F and the driven roller 34F and is driven by the driven roller 34F. The bill BL is pressed against the roller 33F to transmit a downward driving force, and the bill BL is moved downward and conveyed to the switching mechanism 36. The banknote BL is conveyed to the identification conveyance path 43A while changing its direction in the backward direction by hitting the upper distribution surface 36A of the switching mechanism 36, and the tip sliding on the lower conveyance guide surface 42S.

  Subsequently, the discrimination unit 18 includes a drive roller 33D, a driven roller 34D, a drive roller 33C, a driven roller 34C, a drive roller 33B, a driven roller 34B, a reference roller 51, a roller portion of the thickness detection roller unit 52, and a drive. The banknotes BL are sequentially sandwiched between the roller 33A and the driven roller 34A, and the banknotes BL are transported backward in the discrimination transport path 43A, and are fed out to the rear of the discrimination section 18 via the transport path delivery section 80A. At this time, the discrimination unit 18 acquires magnetic information such as magnetic ink on the surface of the banknote BL by the magnetic information acquisition unit 70, acquires image information such as a reflection image and a transmission image of the surface of the banknote BL by the optical information acquisition unit 60, The thickness information acquisition unit 50 acquires the thickness information of the banknote BL. The control part 12 acquires the information of the banknote BL acquired in the magnetic information acquisition part 70, the optical information acquisition part 60, and the thickness information acquisition part 50 as a reading means by a signal transmission means (not shown), and authenticates the banknote BL. Based on the result of the discrimination, the banknote BL is transported to the temporary storage unit 20 and stored, or is transported to the deposit / withdrawal unit 16 and returned.

  Although the operation | movement when the banknote BL is conveyed at the time of a money_receiving | payment process was demonstrated above, the case where the banknote BL is conveyed to the banknote storage 26 or the rejection store | warehouse | chamber 28 from the temporary storage part 20 at the time of a storage process, and a payment process When the banknote BL is conveyed from the banknote storage 26 to the deposit / withdrawal unit 16 or the reject store 28 at the time, the discrimination unit 18 reverses the rotation direction of each roller with respect to the depositing process and appropriately switches the switching mechanism 36. .

[1-5-2. For folded banknotes]
Here, the case where the folded banknote BLd shown in FIG. 8 is conveyed from the deposit / withdrawal part side conveyance path 43C to the discrimination conveyance path 43A will be considered. The folded banknote BLd has a folded portion DE that is folded downward at the left end portion at the rear end portion on the downstream side in the transport direction. Here, the distance from the left end of the folded banknote BLd to the rear end of the fold FL in the fold DE is the end fold distance DS.

  Here, if the end fold distance DS is larger than the roller blade interval CL2, the lower surface of the fold portion DE is supported by both the driving roller 33Dol and the left end blade 36D. The folding part DE does not enter the roller outer space 48o, which is a space between the left edge of the part 42HDol and the left end of the driving roller 33Dol, and is conveyed rearward along the discrimination conveying path 43A.

  On the other hand, as shown in FIG. 10 (A), the folded bill BLd is conveyed at a position where the rear end portion of the fold FL is placed on the left end of the driving roller 33Dol, and the end fold distance DS (FIG. 8) is the roller blade. When the distance CL2 is narrower than that of FIG. 5 (FIG. 5), the lower surface of the bent portion DE is not supported by both the driving roller 33Dol and the leftmost blade 36D. Therefore, FIG. 9A shows the upper frame 40A and the upper frame 40A. There is a possibility that the folded portion DE of the folded bill BLd enters the roller outer space 48o as shown in the lower conveyance guide 42 and the front conveyance guide 32 and the folded bill BLd. At this time, since the slope 42Dol is formed such that the slope depth DP3 (FIG. 7) is larger than the roller blade interval CL2 (FIG. 5), as shown in FIG. The left end portion contacts the slope surface 42DSol without entering below the slope surface 42DSol. Subsequently, when the folded banknote BLd is conveyed backward, the folded banknote BLd is lifted upward while the left end portion of the folded portion DE is in contact with the slope surface 42DSol, and the folded section as shown in FIG. 10 (B). The DE is returned to the transport path 43.

  Accordingly, the discrimination unit 18 can transport the folded bill BLd while preventing the folded portion DE from entering below the slope surface 42DSol and clogging the folded bill BLd. As described above, the roller outer space, which is the space between the left edge of the opening 42HDol and the left end of the driving roller 33Dol, is the folded portion DE of the folded banknote BLd having the folded portion DE formed at the left end on the leading end side in the transport direction. The case of entering 48o has been described, but the folded portion DE of the folded banknote BLd having a folded portion DE formed at the right end on the leading end side in the transport direction is between the right edge of the opening 42HDor and the right end of the drive roller 33Dor. The same applies to the case of entering the roller outer space 48o (not shown), which is a space.

[1-6. Effect]
Here, in the conventional discrimination unit 1018 shown in FIG. 15A in which members corresponding to those in FIG. 9 are given the same reference numerals, the slopes 1042Dor and 1042Dol are substantially the same depth as the slopes 42Dir and 42Dil and the slope 42MB. There was something that was formed with. In this case, when the folded portion DE enters the roller outer space 48o, the left end portion of the folded portion DE enters below the slope surface 1042DSol, and the folded portion DE is not returned to the transport path 43. Therefore, the roller outer space 48o may be clogged as shown in FIG. 15B without exceeding the slope 1042Dol.

  On the other hand, the discrimination part 18 made the slope 42Dol so that the slope depth DP3 was larger than the roller blade interval CL2 (FIG. 5). Thereby, even if the folding part DE enters the roller outer space 48o, the discrimination part 18 makes the left end part of the folding part DE abut on the upper side of the lower end part of the slope surface 42DSol, and the folding part DE is brought into the transport path 43. You can return to

  Here, by omitting the driving rollers 33Dol and 33Dor and providing only the driving rollers 33Dir and 33Dil and omitting the openings 42HDol and 42HDor itself, the space for the folded portion DE of the folded banknote BLd to be eliminated or the driving rollers 33Dol and It is also conceivable that by disposing 33 Dor on the inner side in the left-right direction, the possibility that the folded portion DE of the folded banknote BLd enters the roller outer space 48o is reduced. However, in that case, although the folded portion DE of the folded bill BLd can be prevented from entering the roller outer space 48o, the bill BL cannot be clamped in a wide range by the roller in the left-right direction, so both ends of the bill BL are likely to flutter. As a result, the reading performance of the discrimination unit 18 is degraded.

  On the other hand, the discrimination part 18 arrange | positions the drive rollers 33Dol and 33Dor slightly inside the length of the conveyance width direction of a banknote with the largest conveyance width. For this reason, the discrimination part 18 can suppress the flapping of the left and right ends of the banknote BL, and can perform stable reading in the thickness information acquisition part 50, the optical information acquisition part 60, and the magnetic information acquisition part 70.

  Further, the length of the discrimination conveyance path 43A (FIG. 3) is increased in the front-rear direction, and rollers similar to the driving roller 33C and the driven roller 34C are added between the driving roller 33D and the driven roller 34D and the switching mechanism 36. Therefore, it may be possible to perform stable reading while reducing the conveyance jam. However, in that case, since the identification conveyance path becomes longer, the size of the identification section 18 in the front-rear direction is increased.

  On the other hand, the discrimination unit 18 is provided with only the driving roller 33D and the driven roller 34D as rollers between the magnetic information acquisition unit 70 and the switching mechanism 36. Thereby, the discrimination part 18 can suppress the length of the discrimination conveyance path, and can reduce the size of the discrimination part 18 in the front-rear direction.

  Here, as in the discrimination unit 1118 shown in FIG. 16A in which members corresponding to those in FIG. 9 are assigned the same reference numerals, the depths of the slopes 1142Dir and 1142Dil are the same as the slopes 42Dor and 42Dol, not the slope depth DP2. When the slope depth DP3 is increased, the drive rollers 33Dil and 33Dir are exposed to the transport path 43 to a lower portion than in the discrimination unit 18. For this reason, in the discrimination part 1118, as shown in FIG.16 (B), the folding banknote BLv by which the folding part FV folded in the V shape was formed in a part of front-end | tip part of a conveyance direction at the time of payment processing is a discrimination conveyance path. When 43A is conveyed toward the front, the possibility of clogging by hitting the driving roller 33Dil or 33Dir increases. Further, at the time of deposit processing, even if a folded banknote in which one of the left and right ends of the banknote is folded is conveyed, the folded section of the folded banknote enters the roller outer space 48o outside the driving roller 33Dol or 33Dor. Although there is a possibility, since the possibility of entering the space outside the drive rollers 33Dil and 33Dir is very low, even if a slope similar to the slopes 42Dor and 42Dol is formed on the rear side of the drive rollers 33Dil and 33Dir, the obtained effect is uncommon. Therefore, the depths of the slopes 42Dir and 42Dil are not equal to the slopes 42Dor and 42Dol, the depths of the slopes 42Dir and 42Dil are set to the slope depth DP2 as in the prior art, and only the slopes 42Dor and 42Dol are set to be more than the slope depth DP2. A deep slope depth DP3 is desirable.

  It is also conceivable to increase the depth of the slope 42MB to a slope depth DP3 similar to the slopes 42Dor and 42Dol instead of the slope depth DP1. However, in that case, the possibility that the folded portion FV of the banknote BLv will collide with the magnetic gap roller 72 during the dispensing process as with the discrimination unit 1118 increases, and the proximity to the switching mechanism 36 as will be described later. Therefore, at the time of deposit processing, the folded portion FV of the folded banknote BLv is difficult to enter the slope 42MB in the first place.

  On the other hand, the discrimination unit 18 makes the depth of the slope 42MB shallower than the slopes 42Dor and 42Dol, and sets only the slopes 42Dor and 42Dol corresponding to the roller closest to the switching mechanism 36 to the slope depth DP3. For this reason, the discrimination unit 18 prevents the folded portion DE of the folded bill BLd from being formed unnecessarily deeply up to the slope 42MB where the folded portion DE is difficult to enter, and the folded portion DE of the folded bill BLd hits the magnetic gap roller 72 during the withdrawal process. It can be suppressed and the conveyance performance can be maintained.

  Further, the discrimination unit 18 is configured so that the slope on the rear side of the driven roller 34D is not formed as deep as the slopes 42Dor and 42Dol. Here, at the time of deposit processing, the leading edge of the banknote transported from the deposit / withdrawal unit side delivery unit 80B to the branching unit 43B from the upper side to the lower side changes the transport direction toward the rear, and the lower transport guide surface 42S. Is conveyed to the discrimination conveyance path 43A. For this reason, in the discrimination part 18, the folding part DE tends to enter the opening part formed in the lower conveyance guide surface 42S on which the leading edge of the bill is slid. In contrast, the discrimination unit 18 is closest to the switching mechanism 36, and only the slopes 42Dor and 42Dol located outside the curve of the curved conveyance path are set to the slope depth DP3. As a result, the discrimination part 18 does not unnecessarily deeply form the slope on the rear side of the driven roller 34D where the folded part DE of the folded banknote BLd is difficult to enter, and the folded part DE of the folded banknote BLd hits the driven roller 34D. Can be suppressed and the conveyance performance can be maintained.

  Further, like the discrimination unit 1218 shown in FIG. 17A in which members corresponding to those in FIG. 15 are given the same reference numerals, the blade 36D on the front side of the driving rollers 33Dol and 33Dor in the switching mechanism 1236 is omitted. Delivery ribs 42R1 and 42R2 that support the lower surface of the folded portion DE of the folded banknote BLd are provided in the lower conveyance guide 1242 where the omitted blade 36D originally rotates, and the folded banknote BLd is folded in the roller outer space 48o. It may be possible to make the part DE difficult to enter. However, in that case, the portion of the rotating shaft 36C where the blade 36D is originally fixed is exposed in the left-right direction larger than the discriminating portion 1018. Therefore, the folded portion DE of the folded bill BLd collides with the rotating shaft 36C and is folded. The bills BLd are easily jammed.

  On the other hand, the discriminating unit 18 can prevent the rotating shaft 36C from being exposed to a large extent, and therefore prevents the folded portion DE of the folded banknote BLd from colliding with the rotating shaft 36C. Quality can be kept.

  According to the above configuration, the discrimination unit 18 switches the conveyance direction of the bill BL with the lower conveyance guide 42 in which the conveyance path 43 of the bill BL as a paper sheet is formed and the plurality of openings 42HM and 42HD are formed. A switching mechanism 36 and a plurality of magnetic gap rollers 72 and drive rollers 33D that are exposed to the transport path 43 through the openings 42HM and 42HD and are arranged in the transport width direction orthogonal to the transport direction of the bills BL are provided. The lower conveyance guide 42 has a slope 42MBS as a first inclined surface inclined in a direction along the conveyance direction at an opening 42HM as a first opening, and a switching mechanism than the opening 42HM. A second inclined surface, which is an inclined surface deeper than the slope surface 42MBS, on the outer opening 42HDo as a second opening in which the drive roller 33D close to 36 is disposed. Outer slope surface 42DSo of Te is to be formed. Thereby, even if the folding part DE of the banknote BLd enters the roller outer space 48o between the outer opening 42HDo and the driving roller 33D, the discrimination unit 18 conveys the folding part DE by the outer slope surface 42DSo. Returning to the path 43 side, the folded banknote BLd can be continuously conveyed.

[2. Second Embodiment]
[2-1. Configuration of banknote deposit and withdrawal machine]
As shown in FIG.1 and FIG.2, the banknote depositing / withdrawing machine 110 of the automatic teller machine 101 by 2nd Embodiment is compared with the banknote depositing / withdrawing machine 10 of the automatic teller machine 1 by 1st Embodiment. Although the discrimination unit 118 is different from the discrimination unit 18, the rest is configured in the same manner.

[2-2. Configuration of the identification section]
As shown in FIG. 3 and FIG. 11 in which members corresponding to those in FIG. 5 are assigned the same reference numerals, the discrimination unit 118 is different from the discrimination unit 18 in that the lower conveyance guide 142 is different from the lower conveyance guide 42. Others are configured in the same way. The lower conveyance guide 142 is configured similarly to the lower conveyance guide 42 except that the outer slope 142Do (slopes 142Dol and 142Dor) is different from the outer slope 42Do (slopes 42Dol and 42Dor). .

[2-3. Slope configuration]
As shown in FIGS. 11 and 12, the slopes 142Dol and 142Dor (hereinafter collectively referred to as the outer slope 142Do) are V-shaped with the same cross section. The slopes 142Dol and 142Dor have a slope depth DP3, similar to the slopes 42Dol and 42Dor. On the slope 142Dol, an inner inclined surface 52i is formed on the right half that is the inner side in the transport width direction, and an outer inclined surface 52o is formed on the left half that is the outer side in the transport width direction. The contact point between the inner inclined surface 52i and the outer inclined surface 52o has the same position in the left-right direction as the center in the width direction of the drive roller 33Dol, and extends along the transport direction. The inner inclined surface 52i is inclined upward as it goes from the front end to the rear end, and is inclined upward as it goes from the left end to the right end, that is, from the upstream side to the downstream side in the conveyance direction of the banknote over the drive roller 33Dol. Inclined with respect to the conveyance direction from the roller shaft side to the conveyance path 43 side as it goes to the side, while moving from the roller axis side to the conveyance path 43 side with respect to the conveyance direction as it goes from the outside to the inside in the conveyance width direction. This is a sloped plane slope surface. The outer inclined surface 52o is inclined upward as it goes from the front end to the rear end, and is inclined upward as it goes from the right end to the left end, that is, from the upstream side to the downstream side in the conveyance direction of the banknotes over the drive roller 33Dol. As it moves from the roller shaft side to the conveyance path 43 side, it is inclined with respect to the conveyance direction, and from the inner side to the outer side in the conveyance width direction, the roller shaft side moves toward the conveyance path 43 side. This is a sloped plane slope surface.

[2-4. Operation of discrimination part]
Here, the case where the folded banknote BLd shown in FIG. 8 is conveyed from the deposit / withdrawal part side conveyance path 43C to the discrimination conveyance path 43A as in the first embodiment will be considered.

  Here, as shown in FIG. 13A, when the folded banknote BLd is conveyed in a state where the left end portion of the folded portion DE enters the roller outer space 48o, the left end portion of the folded portion DE is moved to the outer inclined surface 52o. Abut. When the folded bill BLd is further conveyed rearward, the folded bill BLd is further folded so that the left end of the folded portion DE moves to the right as shown in FIG. 13B (ie, the folded portion DE is further folded). And so on) while being bent by the outer inclined surface 52o, the bent portion DE is returned to the transport path 43.

  On the other hand, as shown in FIG. 14A, when the folded bill BLd is conveyed in a state where the left end portion of the folded portion DE enters the roller inner space 48i, the left end portion of the folded portion DE contacts the inner inclined surface 52i. Touch. When the folded banknote BLd is further conveyed rearward, as shown in FIG. 14B, the folded banknote BLd is moved so that the left end of the folded section DE moves to the left side (that is, the folded section DE is expanded). (Ii) While being widened by the inner inclined surface 52 i, it is lifted upward, and the bent portion DE is returned to the transport path 43.

  As a result, the discrimination unit 118 can transport the folded bill BLd while preventing the folded portion DE from entering the lower side of the outer inclined surface 52o and the inner inclined surface 52i and clogging the folded bill BLd. The above describes the case where the folded portion DE of the folded banknote BLd having the folded portion DE formed at the left end portion on the front end side in the transport direction enters the roller outer space 48o or the roller inner space 48i. The same applies to the case where the folded portion DE of the folded bill BLd having the folded portion DE formed at the right end portion enters the roller outer space 48o or the roller inner space 48i of the opening 42HDor.

[2-5. Effect]
In this way, the discrimination unit 118 lifts the folded portion DE of the folded banknote BLd conveyed with the left end of the folded portion DE entering the roller outer space 48o while folding the folded bill DE by the outer inclined surface 52o. As a result, the discrimination unit 118 transports the folded bill BLd while keeping the left end portion of the folded portion DE away from the outer wall surface 50o. Therefore, the load that the folded bill BLd slides on the outer wall surface 50o and is applied to the folded bill BLd. This reduces the amount of folded bills BLd.

  The discrimination unit 118 lifts the folded portion DE of the folded bill BLd conveyed with the left end portion of the folded portion DE entering the roller inner space 48i while spreading it by the inner inclined surface 52i. As a result, the discrimination unit 118 transports the folded bill BLd while keeping the left end portion of the folded portion DE away from the inner wall surface 50i. Therefore, the load that the folded bill BLd slides on the inner wall surface 50i and is applied to the folded bill BLd. This reduces the amount of folded bills BLd.

  In addition, the discrimination unit 118 according to the second embodiment has substantially the same operational effects as the discrimination unit 18 according to the first embodiment.

[3. Other Embodiments]
In the above-described first embodiment, the case where the slope surfaces 42DSol and 42DSor of the slopes 42Dol and 42Dor have a planar shape has been described. The present invention is not limited to this, and the slope surface may have various shapes such as a curved shape. In short, any surface that is inclined with respect to the transport direction and returns the abutted banknote to the transport path 43 side may be used.

  Further, in the above-described second embodiment, the case where the slopes 142Dol and 142Dor have a V-shaped cross section has been described. The present invention is not limited to this, and may have various shapes such as a U-shaped cross section. In short, any shape may be used as long as the end in the conveyance width direction of the bent portion DE is lifted away from the inner wall surface 50i and the outer wall surface 50o. Further, the inner inclined surface 52i is omitted and the right end portion of the outer inclined surface 52o is extended to the inner wall surface 50i, or the outer inclined surface 52o is omitted and the left end portion of the inner inclined surface 52i is extended to the outer wall surface 50o. May be. As described above, when the slope surface is a left-up or right-up slope inclined with respect to the conveyance width direction, the folded portion DE of the folded bill BLd can be lifted or lifted by the slope surface while being folded. It is possible to make it difficult for the end in the transport width direction to slide with the inner wall surface 50i or the outer wall surface 50o.

  Further, in the above-described embodiment, the case where the slope depth DP3 is made larger than the roller blade interval CL2 (FIG. 5) has been described. The present invention is not limited to this, and the slope depth DP3 may be set to at least the roller blade interval CL2. In short, it is only necessary that the bent portion DE enters below the slope surface. Further, when the blade interval CL1 is narrower than the roller blade interval CL2, for example, when the width of the blade 36D is larger than the drive roller 33D, the slope depth DP3 may be set to be at least larger than the blade interval CL1. . In short, in the case of the slope 42Dol, the slope depth DP3 is either the one blade 36D on the left side of the slope 42Dol and the driving roller 33Dol or the other blade 36D adjacent to the right side of the one blade 36D. As long as it is larger than the shorter one of the distances to the one close to the one blade 36D. In that case, the lower surface of the folded banknote BLd is supported to the left end of the drive roller 33Dol or the other blade 36D, and the rear end of the fold FL is on the left side of the left end. Even if it is the folded banknote BLd in which is positioned, it can be prevented from clogging the roller outer space 48o. In the case of the slope 42 Dor, the same applies only by reversing left and right.

  Further, in the above-described embodiment, the case where the slope depth DP3 is made larger than the roller blade interval CL2 (FIG. 5) has been described. The present invention is not limited to this. Even if the slope depth DP3 is equal to or less than the roller blade interval CL2, as long as the slope depth DP3 is at least deeper than the slope depths DP1 and DP2, the folded portion of the folded bill BLd is more than the conventional discrimination portion. It is possible to make it difficult for the DE to clog the roller outer space 48o.

  Further, in the above-described embodiment, the case where four drive rollers 33A, 33B, 33C and 33D and four driven rollers 34A, 34B, 34C and 34D are provided side by side has been described. The present invention is not limited to this, and an arbitrary number such as three or five or more may be provided.

  Furthermore, in 1st Embodiment mentioned above, the case where it arrange | positions in the inside of the discrimination part 18 in order of thickness information acquisition part 50 from the back to the front, the optical information acquisition part 60, and the magnetic information acquisition part 70 is described. It was. The present invention is not limited to this, and the thickness information acquisition unit 50, the optical information acquisition unit 60, and the magnetic information acquisition unit 70 may be arranged in the discrimination unit 18 in any order. In addition, any of the thickness information acquisition unit 50, the optical information acquisition unit 60, and the magnetic information acquisition unit 70 may be omitted.
