In addition,, as shown in Fig. 6 and Fig. 7, at the inner face of the first blade 56a and the second blade 56b, be respectively arranged with protrusion 57.In addition, in the first blade 56a and the second blade 56b, be respectively arranged with notch 58.Here, as shown in Fig. 5 or Fig. 8, about a pair of blade 56(adjacent on the circumferencial direction at matrix part 54, the first blade 56a and the second blade 56b), from the normal direction of matrix part 54, the protrusion 57 of a blade is relative with the notch 58 of another blade.Particularly, about the first adjacent blade 56a and the second blade 56b, the protrusion 57 of the first blade 56a extends to the notch 58 of the second blade 56b or connects this notch 58 and extend, in addition, the protrusion 57 of the second blade 56b extends to the notch 58 of the first blade 56a or connects this notch 58 and extend.Therefore, the protrusion 57 of the first blade 56a does not contact the second blade 56b, and in addition, the protrusion 57 of the second blade 56b does not contact the first blade 56a yet.

Thus, about the first adjacent blade 56a and the second blade 56b, as shown in Figure 8, from matrix part 54 axially, the protrusion 57 of the first blade 56a overlaps with the second blade 56b and the protrusion 57 of the second blade 56b overlaps with the first blade 56a.In addition, about the first adjacent blade 56a and the second blade 56b, from the normal direction of matrix part 54, the protrusion 57 of the first blade 56a is positioned at the scope of the notch 58 of the second blade 56b, and the protrusion 57 of the second blade 56b is positioned at the scope of the notch 58 of the first blade 56a.Therefore, the protrusion 57 of the first blade 56a or the second blade 56b does not contact another blade.

In addition, in the impeller 52 of present embodiment, also can replace, at the inner face of the first blade 56a and the second blade 56b, protrusion 57 is set, in the outside of the first blade 56a and the second blade 56b, protrusion 57 is set.When protrusion 57, in the situation that the outside of the first blade 56a and the second blade 56b arranges, protrusion 57 is contrary with the position relationship of notch 58, and the order of pressing protrusion 57, notch 58 towards front end from matrix part 54 sides forms.Now, also about a pair of blade 56 adjacent on the circumferencial direction at matrix part 54, from the normal direction of matrix part 54, the protrusion 57 of a blade is relative with the notch 58 of another blade.

In addition, in the impeller 52 of present embodiment, also can replace, in the first blade 56a and the second blade 56b, notch 58 is set respectively, peristome is set.Now, also about the first adjacent blade 56a and the second blade 56b, the protrusion 57 of the first blade 56a extends to the peristome forming in the second blade 56b or connects this peristome and extend, in addition, the protrusion 57 of the second blade 56b extends to the peristome forming in the first blade 56a or connects this peristome and extend.

In addition,, in the impeller 52 of present embodiment, the first blade 56a and the second blade 56b form and can carry out elastic deformation.Particularly, these the first blade 56a and the second blade 56b are formed by the material of the carried out elastic deformation of resin rubber etc., or the first blade 56a and the second blade 56b are arranged in matrix part 54 can carry out the mode of elastic deformation.

Action while then, the vane type accumulation mechanism 50 forming to the structure by such from trucking department 18 transmission bank note being described.

As mentioned above, the impeller 52 of vane type accumulation mechanism 50, in the action of bank note treatment device 10, rotates to the anticlockwise direction in Fig. 2 all the time by drive division.And, if be transmitted bank note from trucking department 18, the part of the close end of the left and right of this bank note the impeller 52 of pair of right and left separately in catch respectively between the first blade 56a of arranging and the second blade 56b.Now, about the first adjacent blade 56a and the second blade 56b, because extending to the notch 58 of the second blade 56b or connect this notch 58, extends the protrusion 57 of the first blade 56a, in addition, the protrusion 57 of the second blade 56b extends to the notch 58 of the first blade 56a or connects this notch 58 and extend, so as shown in Figure 9, the bank note P catching between the first blade 56a and the second blade 56b is bent by protrusion 57, is endowed rigidity.

More specifically explanation, in the situation that it is strong to be sent to the rigidity of bank note of impeller 52 from trucking department 18, when catching between the first blade 56a of this bank note in impeller 52 and the second blade 56b, the first blade 56a or the second blade 56b elastic deformation, thus this bank note is firmly held between the first blade 56a and the second blade 56b.Now, this bank note is by protrusion 57 and slight curvature is endowed rigidity.

In addition, in the situation that a little less than trucking department 18 is sent to the rigidity of bank note of impeller 52, when catching between the first blade 56a of this bank note in impeller 52 and the second blade 56b, between these the first blade 56a and the second blade 56b, insert the depths between blade 56a, 56b.Now, this bank note remains between the first blade 56a and the second blade 56b frailly.In addition, now, this bank note is endowed rigidity by protrusion 57 bending significantly.

Thus, in the situation that it is strong and weak to be sent to the rigidity of bank note of impeller 52 from trucking department 18, this bank note all remains between the first blade 56a and the second blade 56b reliably.

Afterwards, the impeller 52 of pair of right and left separately in, the bank note of catching between the first blade 56a and the second blade 56b abut to accumulation portion 30 bottom surface and from discharging between

blade

56a, 56b and being sent to accumulation portion 30.Thus, from impeller 52, transmit one by one bank note to accumulation portion 30, the state accumulation of a plurality of bank note to be arranged in this accumulation portion 30.

As previously discussed, according to the impeller 52 of present embodiment, at the inner face of each blade 56 or at least one side of outside, be provided with protrusion 57, about a pair of blade 56(the first blade 56a and the second blade 56b adjacent on the circumferencial direction at matrix part 54), from matrix part 54 axially, a blade 56(for example, the first blade 56a) protrusion 57 and another blade 56(are for example, the second blade 56b) coincidence (with reference to Fig. 8), and a blade 56(for example, the first blade 56a) protrusion 57 and another blade 56(are for example, the second blade 56b) do not contact (with reference to Fig. 5).Therefore, when the bank note that is sent to impeller 52 is at adjacent a pair of blade 56(the first blade 56a and the second blade 56b) between while catching, this bank note is by the crooked rigidity (with reference to the bank note P in Fig. 9) that is endowed of protrusion 57 arranging in the inner face at each blade 56 or outside.Thus, in the situation that it is strong and weak to be sent to the rigidity of bank note of impeller 52 from trucking department 18, this bank note all remains between the first blade 56a and the second blade 56b reliably, thus, intensity regardless of the original rigidity of bank note, can both be suppressed at 56 bank note of catching of a pair of blade from these a pair of blade 56(the first blade 56a and the second blade 56b) between situation about flying out mistakenly.

In addition, in the impeller 52 of present embodiment, as shown in Fig. 6 (a) and Fig. 7 (a), on the circumferencial direction of matrix part 54 adjacent a pair of blade 56, the first blade 56a and the second blade 56b regard as symmetrical shape from the normal direction of matrix part 54.In addition, now, be respectively arranged with notch 58 or peristome (not shown) in the first blade 56a and the second blade 56b, from the normal direction of matrix part 54, the protrusion 57 of a blade 56 is relative with notch 58 or the peristome of another blade 56.Therefore the bank note that, is sent to impeller 52 is by extending to notch 58 or peristome or connecting notch 58 or protrusion 57 that peristome the extends crooked rigidity that is endowed reliably.

In addition,, in the impeller 52 of present embodiment, the first blade 56a or the second blade 56b form and can carry out elastic deformation.Therefore, in the situation that it is strong to be sent to the rigidity of bank note of impeller 52, by the first blade 56a or the second blade 56b, carry out elastic deformation, also this bank note can be remained on reliably between the first blade 56a and the second blade 56b.

In addition, the structure as the impeller arranging in bank note treatment device 10, is not limited to the mode as shown in Fig. 4 to Fig. 9.Below, use other modes of Figure 10 and Figure 11 explanation impeller of setting in bank note treatment device 10.Figure 10 means the block diagram of other structures of the impeller arranging in the bank note treatment device of present embodiment, and Figure 11 means the block diagram of the structure of the blade arranging in the impeller shown in Figure 10.

As shown in figure 10, the impeller 72 of variation has the matrix part 74 of drum and a plurality of blades 76 that extend towards the reciprocal foreign side of the hand of rotation with impeller 72 from the outer peripheral face of this matrix part 74.And 76, a pair of blade adjacent on the circumferencial direction of matrix part 74 is caught bank note.Here, the blade 76 arranging in impeller 72 all becomes identical shape, but on the circumferencial direction of matrix part 74 adjacent a pair of blade 76 be configured in matrix part 74 axially on the position of mutually departing from.That is,, when seeing from the normal direction of matrix part 74, adjacent a pair of blade 76 does not overlap.In other words, when seeing from the normal direction of matrix part 74, in adjacent a pair of blade 76, a blade 76 is arranged on the territory, right half-court in matrix part 74, and another blade 76 is arranged on the territory, left half-court in matrix part 74.In addition, at matrix part 74 center, be provided with bearing portion 73, by this bearing portion 73, axle (not shown) is stressed.And by drive division (not shown) S. A., impeller 72 is rotation together also.

Each blade 76 in the impeller 72 of variation also can become one with matrix part 74, or each blade 76 also can load and unload respectively the outer peripheral face that is arranged on freely matrix part 74.

In addition,, as shown in Figure 10 and Figure 11, at the inner face of each blade 76, be respectively arranged with protrusion 77.And about a pair of blade 76 adjacent on the circumferencial direction at matrix part 74, from matrix part 74 axially, the protrusion 77 of a blade 76 overlaps with another blade 76.In addition, about adjacent a pair of blade 76, due to these blades 76 be configured in matrix part 74 axially on the position of mutually departing from, so the protrusion 77 of a blade 76 does not contact with another blade 76.

In addition, also can replace protrusion 77 to be arranged on the inner face of each blade 76, protrusion 77 is arranged on the outside of each blade 76.Now, about a pair of blade 76 adjacent on the circumferencial direction at matrix part 74, from matrix part 74 axially, the protrusion 77 of a blade 76 overlaps with another blade 76.

In addition,, in the impeller 72 of variation, each blade 76 forms and can carry out elastic deformation.Particularly, each blade 76 is formed by the material of the carried out elastic deformation of resin rubber etc., or each blade 76 is arranged in matrix part 74 can carry out the mode of elastic deformation.

If transmit bank note to the impeller 72 shown in Figure 10 and Figure 11 from trucking department 18, this bank note is caught in 76, adjacent a pair of blade.Now, about adjacent a pair of blade 76, from matrix part 74 axially, because the protrusion 77 of a blade 76 overlaps with another blade 76, so at 76 bank note of catching of a pair of blade by the crooked rigidity that is endowed of protrusion 77.

More specifically explanation, in the situation that it is strong to be sent to the rigidity of bank note of impeller 72 from trucking department 18, when 76, a pair of blade of this bank note in impeller 72 caught, carry out elastic deformation, thereby this bank note is firmly held in 76, a pair of blade by blade 76.Now, this bank note is by protrusion 77 and slight curvature is endowed rigidity.

In addition, in the situation that a little less than trucking department 18 is sent to the rigidity of bank note of impeller 72, when 76, a pair of blade of this bank note in impeller 72 caught, be inserted into deep at 76 these bank note of a pair of blade.Now, this bank note remains on 76, a pair of blade frailly.In addition, now, this bank note is by the protrusion 77 crooked rigidity that is endowed significantly.

Afterwards, in impeller 72, at 76 bank note of catching of a pair of blade, from 76, these blades, discharge and be sent to accumulation portion 30.Thus, from impeller 72, transmit one by one bank note to accumulation portion 30, the state accumulation of a plurality of bank note to be arranged in this accumulation portion 30.

As previously discussed, in the impeller 72 as shown in Figure 10 and Figure 11, also with the impeller 52 shown in Fig. 4 to Fig. 9 in the same manner, at the inner face of each blade 76 or at least one side of outside, be provided with protrusion 77, about a pair of blade 76 adjacent on the circumferencial direction at matrix part 74, from matrix part 74 axially, the protrusion 77 of a blade 76 overlaps with another blade 76, and the protrusion 77 of a blade 76 does not contact with another blade 76.Therefore,, when the bank note that is sent to impeller 72 is when 76, adjacent a pair of blade is caught, this bank note is by the crooked rigidity that is endowed of protrusion 77 arranging in the inner face at each blade 76 or outside.Thus, in the situation that it is strong and weak to be sent to the rigidity of bank note of impeller 72 from trucking department 18, this bank note all remains on 76, a pair of blade reliably, thus, intensity regardless of the original rigidity of bank note, can both be suppressed at 76 bank note of catching of a pair of blade from 76 situations about flying out mistakenly of these a pair of blades.

In addition use, other the mode again of Figure 12 and Figure 13 explanation impeller of setting in bank note treatment device 10.Figure 12 means the block diagram of other structure again of the impeller arranging in the bank note treatment device of present embodiment, and Figure 13 means the block diagram of the structure of the blade arranging in the impeller shown in Figure 12.

As shown in figure 12, the impeller 82 of other variation has the matrix part 84 of drum and a plurality of blades 86 that extend towards the reciprocal foreign side of the hand of rotation with impeller 82 from the outer peripheral face of this matrix part 84.And 86, a pair of blade adjacent on the circumferencial direction of matrix part 84 is caught bank note.Here, the blade 86 arranging in impeller 82 all becomes identical shape.In addition, at matrix part 84 center, be provided with bearing portion 83, by this bearing portion 83, axle (not shown) is stressed.And by drive division (not shown) S. A., impeller 82 is rotation together also.

Each blade 86 in the impeller 82 of variation both can become one with matrix part 84, or each blade 86 also can load and unload respectively the outer peripheral face that is arranged on freely matrix part 84.

In addition,, as shown in Figure 12 and Figure 13, at the inner face of each blade 86, be provided with protrusion 87.In addition, in each blade 86, be provided with peristome 88.Here, as shown in figure 12, about a pair of blade 86 adjacent on the circumferencial direction at matrix part 84, from the normal direction of matrix part 84, the protrusion 87 of a blade 86 is relative with the peristome 88 of another blade 86.Particularly, the protrusion 87 about adjacent 86, one blades 86 of a pair of blade extends to the peristome 88 of another blade 86 or connects this peristome 88 and extend.Therefore, the protrusion 87 of a blade 86 does not contact with another blade 86.

Thus, about adjacent a pair of blade 86, from matrix part 84 axially, the protrusion 87 of a blade 86 overlaps with another blade 86.In addition,, about adjacent a pair of blade 86, from the normal direction of matrix part 84, the protrusion 87 of a blade 86 is positioned at the scope of the peristome 88 of another blade 86.Therefore, the protrusion 87 of a blade 86 does not contact with another blade 86.

In addition, in the impeller 82 of variation, also can replace protrusion 87 to be arranged on the inner face of blade 86, protrusion 87 is arranged on the outside of blade 86.In the situation that protrusion 87 is arranged on the outside of blade 86, protrusion 87 is contrary with the position relationship of peristome 88, from matrix part 84 sides, towards front end, forms successively protrusion 87, peristome 88.Now, about a pair of blade 86 adjacent on the circumferencial direction at matrix part 84, from the normal direction of matrix part 84, the protrusion 87 of a blade 86 is relative with the peristome 88 of another blade 86.

In addition, in the impeller 82 of variation, also can replace, in each blade 86, peristome 88 is set, notch is set.Now, about the protrusion 87 of adjacent 86, one blades 86 of a pair of blade, extend to the notch forming in another blade 86 or connect this notch and extend.

In addition,, in the impeller 82 of variation, each blade 86 forms and can carry out elastic deformation.Particularly, each blade 86 is formed by the material of the carried out elastic deformation of resin rubber etc., or each blade 86 is arranged in matrix part 84 can carry out the mode of elastic deformation.

If transmit bank note to the impeller 82 as shown in Figure 12 and Figure 13 from trucking department 18, this bank note is caught in 86, adjacent a pair of blade.Now, about adjacent a pair of blade 86, from matrix part 84 axially, because the protrusion 87 of a blade 86 overlaps with another blade 86, so at 86 bank note of catching of a pair of blade by the crooked rigidity that is endowed of protrusion 87.

More specifically explanation, in the situation that it is strong to be sent to the rigidity of bank note of impeller 82 from trucking department 18, when 86, a pair of blade of this bank note in impeller 82 caught, by blade 86 elastic deformations, thereby this bank note is firmly held in 86, a pair of blade.Now, this bank note is endowed rigidity by protrusion 87 slight curvatures.

In addition, in the situation that a little less than trucking department 18 is sent to the rigidity of bank note of impeller 82, when 86, a pair of blade of this bank note in impeller 82 caught, be inserted into deep at 86 these bank note of a pair of blade.Now, this bank note remains on 86, a pair of blade frailly.In addition, now, this bank note is by the protrusion 87 crooked rigidity that is endowed significantly.

Afterwards, in impeller 82, at 86 bank note of catching of a pair of blade, from 86, these blades, discharge and be sent to accumulation portion 30.Thus, from impeller 82, transmit one by one bank note to accumulation portion 30, the state accumulation of a plurality of bank note to be arranged in this accumulation portion 30.

As previously discussed, in the impeller 82 as shown in Figure 12 and Figure 13, also with the impeller 52 shown in Fig. 4 to Fig. 9 in the same manner, at the inner face of each blade 86 or at least one side of outside, be provided with protrusion 87, about a pair of blade 86 adjacent on the circumferencial direction at matrix part 84, from matrix part 84 axially, the protrusion 87 of a blade 86 overlaps with another blade 86, and the protrusion 87 of a blade 86 does not contact with another blade 86.Therefore,, when the bank note that is sent to impeller 82 is when 86, adjacent a pair of blade is caught, this bank note is by the crooked rigidity that is endowed of protrusion 87 arranging in the inner face at each blade 86 or outside.Thus, in the situation that it is strong and weak to be sent to the rigidity of bank note of impeller 82 from trucking department 18, this bank note all remains on 86, a pair of blade reliably, thus, intensity regardless of the original rigidity of bank note, can both be suppressed at 86 bank note of catching of a pair of blade from 86 situations about flying out mistakenly of these a pair of blades.

Then the blade that, uses Figure 14 and Figure 15 explanation to arrange in impeller all becomes other the variation again of identical shape.Figure 14 means the lateral plan of other structure again of the impeller arranging in the bank note treatment device of present embodiment, and Figure 15 means the block diagram of the structure of the blade arranging in the impeller shown in Figure 14.

As shown in figure 14, then the impeller 92 of other variation there are the matrix part 94 of drum and a plurality of blades 96 that extend towards the reciprocal foreign side of the hand of rotation with impeller 92 from the outer peripheral face of this matrix part 94.And 96, a pair of blade adjacent on the circumferencial direction of matrix part 94 is caught bank note.As mentioned above, the blade 96 arranging in impeller 92 all becomes identical shape.In addition, at matrix part 94 center, be provided with bearing portion 93, by this bearing portion 93, axle (not shown) is stressed.And by drive division (not shown) S. A., impeller 92 is rotation together also.

Further each blade 96 in the impeller 92 of variation both can become one with matrix part 94, or each blade 96 also can load and unload respectively the outer peripheral face that is arranged on freely matrix part 94.

In the impeller 92 of the further variation as shown in Figure 14 and Figure 15, in each blade 96, protrusion is not set.But near the position front end of each blade 96 is crooked with V-shape or U word shape towards the inner side of this blade 96.In Figure 14 and Figure 15, near the position front end of blade 96 is represented by reference marks 97 with the part of V-shape or the bending of U word shape towards inner side.In addition, in each blade 96, be provided with peristome 98.And, relative with the peristome 98 of another blade 96 as the sweep 97 of the specific part in a blade 96.Particularly, about the sweep 97 in 96, one blades 96 of adjacent a pair of blade, extend to the peristome 98 of another blade 96 or connect this peristome 98 and extend.Therefore, the sweep 97 in a blade 96 does not contact with another blade 96.

Thus, about adjacent a pair of blade 96, from matrix part 94 axially, the sweep 97 in a blade 96 overlaps with another blade 96.In addition,, about adjacent a pair of blade 96, from the normal direction of matrix part 94, the sweep 97 in a blade 96 is positioned at the scope of the peristome 98 of another blade 96.Therefore, sweep 97 does not contact with another blade 96.

In addition, in the impeller 92 of further variation, also can replace, in each blade 96, peristome 98 is set, and notch is set.Now, about the sweep 97 in 96, one blades 96 of adjacent a pair of blade, also extend in another blade 96 peristome forming or connect this peristome and extend.

In addition,, in the impeller 92 of variation, each blade 96 forms and can carry out elastic deformation.Particularly, each blade 96 is formed by the material of the carried out elastic deformation of resin rubber etc., or each blade 96 is arranged in matrix part 94 can carry out the mode of elastic deformation.

If transmit bank note to the impeller 92 as shown in Figure 14 and Figure 15 from trucking department 18, this bank note is caught in 96, adjacent a pair of blade.Now, about adjacent a pair of blade 96, from matrix part 94 axially, because the sweep 97 in a blade 96 overlaps with another blade 96, so be endowed rigidity at 96 bank note of catching of a pair of blade by sweep 97 bendings in a blade 96.

More specifically explanation, in the situation that it is strong to be sent to the rigidity of bank note of impeller 92 from trucking department 18, when 96, a pair of blade of this bank note in impeller 92 caught, by blade 96 elastic deformations, this bank note is firmly held in 96, a pair of blade.Now, this bank note is endowed rigidity by sweep 97 slight curvatures in a blade 96.

In addition, in the situation that a little less than trucking department 18 is sent to the rigidity of bank note of impeller 92, when 96, a pair of blade of this bank note in impeller 92 caught, be inserted into deep at 96 these bank note of a pair of blade.Now, this bank note remains on 96, a pair of blade frailly.In addition, now, this bank note is by the crooked rigidity that is endowed significantly of the sweep 97 in a blade 96.

Afterwards, in impeller 92, at 96 bank note of catching of a pair of blade, from 96, these blades, discharge and be sent to accumulation portion 30.Thus, from impeller 92, transmit one by one bank note to accumulation portion 30, the state accumulation of a plurality of bank note to be arranged in this accumulation portion 30.

As previously discussed, in the impeller 92 as shown in Figure 14 and Figure 15, also about a pair of blade 96 adjacent on the circumferencial direction at matrix part 94, from matrix part 94 axially, sweep 97 as the specific part in a blade 96 overlaps with another blade 96, and the described sweep 97 in a blade 96 does not contact with another blade 76.Therefore,, when the bank note that is sent to impeller 92 is when 96, adjacent a pair of blade is caught, this bank note is by the crooked rigidity that is endowed of the sweep 97 in each blade 96.Thus, in the situation that it is strong and weak to be sent to the rigidity of bank note of impeller 92 from trucking department 18, this bank note all remains on 96, a pair of blade reliably, thus, intensity regardless of the original rigidity of bank note, can both be suppressed at 96 bank note of catching of a pair of blade from 96 situations about flying out mistakenly of these a pair of blades.

Then, use other the mode again of Figure 16 to Figure 18 explanation impeller of setting in bank note treatment device 10.Figure 16 means the section-drawing of other structure again of the impeller arranging in the bank note treatment device of present embodiment, Figure 17 means the section-drawing of the structure of the blade arranging in the impeller shown in Figure 16, Figure 18 means the block diagram of the structure of the blade arranging in the impeller shown in Figure 16, (a) being the block diagram while seeing blade from outside, is (b) block diagram while seeing blade from inner side.

As shown in figure 16, then the impeller 102 of other variation there are the matrix part 104 of drum and a plurality of blades 106 that extend towards the reciprocal foreign side of the hand of rotation with impeller 102 from the outer peripheral face of this matrix part 104.And 106, a pair of blade adjacent on the circumferencial direction of matrix part 104 is caught bank note.Here, the blade 106 arranging in impeller 102 all becomes identical shape.In addition, at matrix part 104 center, be provided with bearing portion 103, by this bearing portion 103, axle (not shown) is stressed.And by drive division (not shown) S. A., impeller 102 is rotation together also.

Further each blade 106 in the impeller 102 of variation both can become one with matrix part 104, or each blade 106 also can load and unload respectively the outer peripheral face that is arranged on freely matrix part 104.

In addition,, in the impeller 102 of further variation, as shown in Figure 17 or Figure 18 (b), at the inner face of each blade 106, be provided with protrusion 107.In addition, as shown in Figure 17 or Figure 18 (a), face in each blade 106, that the side of protrusion 107 is not set, be the outside of each blade 106, be provided with the enterable pit part 108 of protrusion 107 of adjacent blade 106.More specifically, as shown in figure 16, about a pair of blade 106 adjacent on the circumferencial direction at matrix part 104, from the normal direction of matrix part 104, the protrusion 107 of a blade 106 is relative with the pit part 108 of another blade 106.And, about the protrusion 107 of adjacent 106, one blades 106 of a pair of blade, enter in the pit part 108 of another blade 106.Therefore, the protrusion 107 of a blade 106 does not contact with another blade 106.

Thus, about adjacent a pair of blade 106, by the protrusion 107 of a blade 106, enter the pit part 108 of another blade 106, thereby from matrix part 104 axially, the protrusion 107 of a blade 106 overlaps with another blade 106.In addition, the protrusion 107 of a blade 106 does not contact with another blade 106.

In addition, in the impeller 102 of variation, also can replace, at the inner face of blade 106, protrusion 107 is set, in the outside of blade 106, protrusion 107 is set.In the situation that protrusion 107 is arranged on the outside of blade 106, protrusion 107 is contrary with the position relationship of pit part 108, from matrix part 104 sides, towards front end, forms successively protrusion 107, pit part 108.Now, also about the protrusion 107 of 106, one blades 106 of a pair of blade adjacent on the circumferencial direction at matrix part 104, enter the pit part 108 of another blade 106.

In addition,, in the impeller 102 of variation, each blade 106 forms and can carry out elastic deformation.Particularly, each blade 106 is formed by the material of the carried out elastic deformation of resin rubber etc., or each blade 106 is arranged in matrix part 104 can carry out the mode of elastic deformation.

If transmit bank note to the impeller 102 as shown in Figure 16 to Figure 18 from trucking department 18, this bank note is caught in 106, adjacent a pair of blade.Now, about adjacent a pair of blade 106, from matrix part 104 axially, because the protrusion 107 of a blade 106 overlaps with another blade 106, so at 106 bank note of catching of a pair of blade by the crooked rigidity that is endowed of protrusion 107.

More specifically explanation, in the situation that it is strong to be sent to the rigidity of bank note of impeller 102 from trucking department 18, when 106, a pair of blade of this bank note in impeller 102 caught, by blade 106, carry out elastic deformation, thereby this bank note is firmly held in 106, a pair of blade.Now, this bank note is by protrusion 107 and slight curvature is endowed rigidity.

In addition, in the situation that a little less than trucking department 18 is sent to the rigidity of bank note of impeller 102, when 106, a pair of blade of this bank note in impeller 102 caught, be inserted into deep at 106 these bank note of a pair of blade.Now, this bank note remains on 106, a pair of blade frailly.In addition, now, this bank note is by the protrusion 107 crooked rigidity that is endowed significantly.

Afterwards, in impeller 102, at 106 bank note of catching of a pair of blade, from 106, these blades, discharge and be sent to accumulation portion 30.Thus, from impeller 102, transmit one by one bank note to accumulation portion 30, the state accumulation of a plurality of bank note to be arranged in this accumulation portion 30.

As previously discussed, in the impeller 102 as shown in Figure 16 to Figure 18, also with the impeller 52 shown in Fig. 4 to Fig. 9 in the same manner, at the inner face of each blade 106 or at least one side of outside, be provided with protrusion 107, about a pair of blade 106 adjacent on the circumferencial direction at matrix part 104, from matrix part 104 axially, the protrusion 107 of a blade 106 overlaps with another blade 106, and the protrusion 107 of a blade 106 does not contact with another blade 106.In addition, face in each blade 106, that the side of protrusion 107 is not set, is provided with the pit part 108 that the protrusion 107 of adjacent blade 106 enters.Therefore,, when the bank note that is sent to impeller 102 is when 106, adjacent a pair of blade is caught, this bank note is by the crooked rigidity that is endowed of protrusion 107 arranging in the inner face at each blade 106 or outside.Thus, in the situation that it is strong and weak to be sent to the rigidity of bank note of impeller 102 from trucking department 18, this bank note all remains on 106, a pair of blade reliably, thus, intensity regardless of the original rigidity of bank note, can both be suppressed at 106 bank note of catching of a pair of blade from 106 situations about flying out mistakenly of these a pair of blades.

The manufacture method of the impeller of present embodiment then, is described.As an example of the manufacture method of the impeller of present embodiment, below explanation in impeller 52 as shown in Figure 5, the manufacture method of the impeller 52 of the type that the first blade 56a and the second blade 56b and matrix part 54 become one.

First, prepare in inside, to arrange respectively a pair of mould of cavity.The shape of the cavity forming in the inside of a pair of mould here, becomes the shape corresponding with impeller 52 as shown in Figure 5.

Then, make a pair of mould carry out form fit, to the cavity ejection formation material in this pair of mould.As formed material, such as the material that uses the carried out elastic deformation of resin rubber etc.

After the cavity ejection formation material in a pair of mould, cooling these moulds and formed material is solidified.Afterwards, by making a pair of mould separated, can obtain the impeller 52 being generated by the formed material that can carry out the material etc. of elastic deformation.Particularly, the impeller 52 obtaining like this becomes a pair of blade 56a adjacent on the circumferencial direction of matrix part 54, the symmetrical shape of 56b, at each blade 56a, the at least one side of the inner face of 56b or outside is provided with protrusion 57, and at each blade 56a, in 56b, be provided with notch 58, about a pair of blade 56a adjacent on the circumferencial direction at

matrix part

54, 56b, from matrix part 54 axially, a blade (for example, the first blade 56a) protrusion 57 and another blade are (for example, the second blade 56b) coincidence and a blade are (for example, the first blade 56a) protrusion 57 and another blade are (for example, the second blade 56b) do not contact.

In addition, preparing in inside, to arrange respectively a pair of mould of cavity, afterwards, make a pair of mould carry out form fit, to the cavity ejection formation material in this pair of mould, then, make a pair of mould carry out separation, in the manufacture method of the impeller of the impeller that acquisition is generated by formed material, except the impeller 52 as shown in Fig. 5 waits, also can manufacture as the various impellers of explanation in the present embodiment, the impeller 72 as shown in Figure 10 etc. particularly.
