In the present embodiment, “the length of the paper sheet along the direction in which the pushing parts 83 and 93 push out toward the openings 80h and 90h in the stacking parts 80 and 90” is simply referred to as “the paper sheet”. The length along the direction of extrusion of the kind ".

As a first aspect, the identification unit 60 detects the type of paper sheet conveyed by the first conveyance unit 31 of the conveyance unit 30, and the apparatus control unit 150 detects the paper sheet detected by the identification unit 60. Based on these types, it is possible to adopt a mode in which the extrusion amounts of the extrusion portions 83 and 93 are determined. More specifically, the paper sheet processing apparatus 100 determines the types of paper sheets used when determining the extrusion amounts of the extrusion units 83 and 93 among the types of paper sheets detected by the identification unit 60, that is, , Currency type, banknote denomination, banknote printing type, check, gift certificate and form type, etc., and the length along the paper sheet extrusion direction (in this embodiment, the length of the paper sheet The device storage unit 155 stores the directional length ") in association with each other (see FIG. 3). When the type of the paper sheet transported by the first transport unit 31 is detected by the identification unit 60, the length along the extrusion direction of the paper sheet associated with the type of the paper sheet is read out. . At this time, the stacking units 80 and 90 on which the paper sheets are stacked are also read from the device storage unit 155. Based on the length of the paper sheets read from the device storage unit 155 along the extrusion direction and the information of the stacking units 80 and 90 in which the target paper sheets are stacked, The amount of extrusion of 93 is determined. In addition, the identification part 60 of this Embodiment is contained in the "first detection part" of a claim.

By the way, the extrusion amount by which the paper sheets are pushed out by the extruding sections 83 and 93 is set so that, for example, a part of the paper sheets is placed on the notched portions 80g and 90g when pushed out. Can do. Moreover, when there is no such notch 80g, 90g, it can also set so that paper sheets may protrude slightly from opening part 80h, 90h when it extrudes. The amount of the paper sheet to be pushed out can be appropriately changed. For example, the “absolute value” of the length of the paper sheet popping out on the cutout portions 80g and 90g and the “absolute value” of the length of the paper sheet popping out from the openings 80h and 90h "Can also be set. This also applies to each aspect described below.

As a second aspect, the identification unit 60 detects the length of the paper sheet conveyed by the first conveyance unit 31 of the conveyance unit 30, and the apparatus control unit 150 detects the paper sheet detected by the identification unit 60. A mode in which the extrusion amounts of the extrusion portions 83 and 93 are determined based on the length of the class can be employed. In this aspect, the stacking units 80 and 90 on which the paper sheets are stacked are also read from the device storage unit 155.

The contents of the paper sheets stored in the container. The dynamic determination mode is a mode in which paper sheets accommodated in the stacking units 80 and 90 are allocated based on the identification result of the identification unit 60 while processing money. Even the second sheet can be assigned. For example, among the stacking units 80 and 90 in which the identified paper sheet type is not allocated to any stacking unit 80 or 90 and allocation is not determined, the stacking unit 80 in which the dynamic determination mode is set. , 90 is assigned to the stacking units 80, 90 with the contents of the identified paper sheets.

Then, the extrusion amounts of the extrusion units 83 and 93 are determined based on the length along the extrusion direction of the paper sheet read from the storage unit 455. Then, when a predetermined number of sheets are accumulated in the accumulating units 80 and 90, based on the amount of extrusion determined by the control unit 450 depending on the type of the sheets accumulated in the accumulating units 80 and 90. The paper sheets accumulated in the accumulation units 80 and 90 are pushed out.

In addition, regarding the types of paper sheets stacked in the stacking units 80 and 90, the operation unit 406 is used to select the type of currency, the denomination of banknotes, the printing type of banknotes, the correctness of paper sheets, and the front and back of paper sheets. In addition, a designation mode, an automatic decision mode, a dynamic decision mode, a mixing mode, and a non-designation mode are set for each of the paper sheet directions.

According to the fourth aspect, the third detection unit 160 for detecting the accumulation state of the paper sheets accumulated in the accumulation units 80 and 90 is provided (see FIGS. 15A to 15D). The control unit 450 determines the extrusion amounts of the extrusion units 83 and 93 based on the detection result by the third detection unit 160. Therefore, as described above, when a predetermined number of sheets are accumulated in the accumulating units 80 and 90, the accumulation of the sheets accumulated in the accumulating units 80 and 90 determined by the control unit 450 is performed. Based on the amount of extrusion depending on the state, the paper sheets stacked in the stacking sections 80 and 90 are extruded.

For this reason, as described above, when a predetermined number of paper sheets are accumulated in the accumulating units 80 and 90, the position of the paper sheets is detected in real time, and the extrusion unit 83, The extrusion amount of 93 is controlled, and the paper sheets accumulated in the accumulation units 80 and 90 are pushed out.

"effect"
Next, effects achieved by the present embodiment having the above-described configuration, which have not yet been described, or particularly important effects will be described.

According to the present invention, the extrusion amount of the extruding sections 83 and 93 is determined based on the type of paper sheets or the length of the paper sheets, or the extruding sections 83 and 93 turn the paper sheets into the openings 80h and 90h. When the paper is pushed out, the position of the paper sheet is detected to control the push-out amount of the push-out portions 83 and 93. For this reason, according to the magnitude | size of paper sheets, the extrusion amount of paper sheets by the extrusion parts 83 and 93 can be made into an appropriate value. Accordingly, even when the paper sheets are small, the paper sheets can be sufficiently pushed out, so that the paper sheets can be easily taken out from the stacking sections 80 and 90. On the other hand, even when the paper sheets are large, the large paper sheets can be pushed out. , 90 can be prevented from falling.

According to the first aspect of the present invention, the identification unit 60 detects the type of paper sheet conveyed by the first conveyance unit 31 of the conveyance unit 30, and the control unit 450 is detected by the identification unit 60. Based on the type of paper sheet, the extrusion amount of the extrusion parts 83 and 93 is determined. More specifically, among the types of paper sheets detected by the identification unit 60, the types of paper sheets used when determining the extrusion amounts of the extruding units 83 and 93, that is, the types of currency, the money of the banknotes. Based on the type of the seed, the printing type of the banknote, the type of the check, the gift certificate, and the form, etc., the length along the pushing direction of the paper sheet is read from the storage unit 455. Further, the stacking units 80 and 90 on which the paper sheets are stacked are also read from the storage unit 455. Then, based on the length along the extrusion direction of the paper sheet read from the storage unit 455 and the information of the stacking units 80 and 90 in which the target paper sheets are stacked, each stacking unit 80. , 90, the extrusion amounts of the extrusion units 83, 93 are determined. For this reason, according to the magnitude | size of the paper sheet derived | led-out based on the kind of paper sheet, the extrusion amount of the paper sheet by each extrusion part 83,93 can be made into an appropriate value.

According to the second aspect of the present invention, the identification unit 60 detects the length of the paper sheet conveyed by the first conveyance unit 31 of the conveyance unit 30, and the control unit 450 is detected by the identification unit 60. Based on the length of the paper sheets, the extrusion amounts of the extrusion sections 83 and 93 are determined. Based on the length of the paper sheets detected by the identification unit 60 and the information of the stacking units 80 and 90 in which the target paper sheets are stacked, the paper sheets are installed in the stacking units 80 and 90. The extrusion amount of the extrusion parts 83 and 93 is determined. For this reason, according to this aspect, the extrusion amount of the paper sheets by the extrusion units 83 and 93 can be set to an appropriate value in accordance with the size of the paper sheets. In addition, in this aspect, when the aspect in which “the length of the paper sheet along the extruding direction” (in this embodiment “the length of the paper sheet in the longitudinal direction”) is directly detected by the identification unit 60 is adopted in this aspect. Is advantageous in that it is not necessary to read out information on the type of paper sheet from the storage unit 455 and the amount of extrusion can be determined based on the length of the actual paper sheet along the extrusion direction. is there.

According to the third aspect of the present invention, the extrusion amounts of the extrusion units 83 and 93 are determined based on the types of paper sheets accumulated in the accumulation units 80 and 90. More specifically, among the types of paper sheets stacked in the stacking units 80 and 90, the type of paper sheets used when determining the extrusion amount of the extrusion units 83 and 93, that is, the type of currency, banknotes The length of the paper sheet in the pushing direction is read from the storage unit 455 on the basis of the denomination, bill printing type, check, gift certificate, and form type. Then, the extrusion amounts of the extrusion units 83 and 93 are determined based on the length along the extrusion direction of the paper sheet read from the storage unit 455. For this reason, according to the size of the paper sheet derived | led-out based on the kind of paper sheet, the extrusion amount of the paper sheet by the extrusion parts 83 and 93 can be made into an appropriate value. In addition, according to this aspect, since the extrusion amount of paper sheets is preset for each stacking unit 80, 90, the type of currency and the denomination of banknotes for each paper sheet identified by the identifying unit 60 This is advantageous in that it is not necessary to determine the amount of extrusion by judging the printing type of banknotes, the types of checks, gift certificates, and forms.

According to the fourth aspect of the present invention, the third detection unit 160 for detecting the accumulation state of the paper sheets accumulated in the accumulation units 80 and 90 is provided (FIGS. 15A to 15D). )), The control unit 450 determines the extrusion amounts of the extrusion units 83 and 93 based on the detection result by the third detection unit 160. For this reason, the amount of extrusion by the extrusion units 83 and 93 can be set to an appropriate value in consideration of the accumulation state of the paper sheets actually accumulated in the accumulation units 80 and 90. Therefore, even if the paper sheets are accumulated in a state different from usual (disturbed for some reason), a desired amount of paper sheets is obtained by the extruding sections 83 and 93. Can only be extruded. For this reason, even if paper sheets are mistakenly accumulated on the front side compared to the normal accumulation position, the paper sheets are unlikely to fall from the accumulation sections 80 and 90. By the way, in the case of small paper sheets, the paper is often accumulated in a disordered state in the accumulating units 80 and 90. Therefore, this aspect is particularly beneficial when processing small paper sheets.

Further, according to this aspect, even when paper sheets of different sizes are mixed and stacked in the stacking units 80 and 90, the leading end (front end) of the paper sheets can be pushed out to a desired position. It is also useful in that it can be done.

When the third detection unit 160 includes a plurality of third detection parts 161a-161d provided in the stacking units 80, 90, the third detection part 160 is based on information from the third detection parts 161a-161d. The accumulation state of paper sheets can be detected. For this reason, it is possible to finely detect at which position the paper sheets are accumulated and at which position the paper sheets are not accumulated, and as a result, the amount of extrusion by the extruding portions 83 and 93 can be determined more finely. it can. More specifically, the position of the rear end (end portion on the rear surface side) of the sheets stacked by the third detection portion 161a provided on the rear surface side of the stacking units 80 and 90 is detected, and the stacking units 80, 90 are detected. It is possible to detect the position of the front end (front side end portion) of the paper sheets accumulated by the third detection portion 161c and the third detection portion 161d provided on the front surface side of 90. As a result, the length of the paper sheet along the extrusion direction can be detected, and the amount of extrusion by the extrusion units 83 and 93 can be determined. It should be noted that the amount of extrusion by the pushing portions 83 and 93 can be determined more finely as the amount of the third detection portions 161a to 161d to be installed is larger. On the other hand, the third detection portions 161a to 161d to be installed are determined. The manufacturing cost of the paper sheet processing apparatus 100 can be reduced by reducing the amount of paper.

According to the fifth aspect of the present invention, when the extruding sections 83 and 93 push the paper sheets toward the openings 80h and 90h in the stacking sections 80 and 90, the position of the paper sheets is detected in real time. A fourth detection unit 170 is provided (see FIGS. 16A to 16D), and the controller 450 pushes out the extrusion units 83 and 93 based on the detection result from the fourth detection unit 170. To control. For this reason, the extrusion amount can be controlled while the actual positions of the paper sheets are detected by the extrusion units 83 and 93. Therefore, it is possible to acquire information in real time and to push out the paper sheet to the position where it is actually desired to be pushed out. For this reason, even if the paper sheets are stacked in a state different from usual (disturbed for some reason), the paper is controlled while appropriately controlling the extrusion sections 83 and 93. Can extrude leaves. For this reason, even if paper sheets are mistakenly accumulated on the front side compared to the normal accumulation position, the paper sheets are unlikely to fall from the accumulation sections 80 and 90. Incidentally, as described above, in the case of small paper sheets, since they are often accumulated in a disordered state in the accumulating units 80 and 90, this aspect is suitable for processing small paper sheets. Especially useful.

Further, according to this aspect, even when paper sheets of different sizes are mixed and stacked in the stacking units 80 and 90, the leading end (front end) of the paper sheets can be pushed out to a desired position. It is also useful in that it can be done.

In addition, when the 4th detection part 170 has several 4th detection parts 171a and 171b provided in the stacking parts 80 and 90, based on the information from each 4th detection part 171a and 171b. It is possible to detect the position information of the paper sheet in real time. For this reason, when pushing out the paper sheets by the extruding sections 83 and 93, it is possible to detect in real time in which position the paper sheet is located and in which position the paper sheet is not located, As a result, the extrusion amount by the extrusion parts 83 and 93 can be controlled more finely. Note that the amount of extrusion by the pushing portions 83 and 93 can be controlled more finely as the amount of the fourth detection portions 171a and 171b to be installed is larger. On the other hand, the fourth detection portions 171a and 171b to be installed are controlled. The manufacturing cost of the paper sheet processing apparatus 100 can be reduced by reducing the amount of paper.

By the way, in each of the first aspect, the second aspect, and the third aspect described above, the extrusion amount is calculated on the assumption that the paper sheet is in contact with the side wall on the rear surface side of the stacking portions 80 and 90. Alternatively, the calculation may be performed on the assumption that a gap of a predetermined length (for example, several millimeters to several centimeters) is provided from the side wall on the rear surface side of the stacking portions 80 and 90. Further, the value of the “predetermined length” may be appropriately changed by inputting from the operation unit 406, for example.

<< Second Embodiment >>
Next, a second embodiment of the present invention will be described. FIGS. 18A to 18D are diagrams for explaining the second embodiment of the present invention.

In the first embodiment, the controller 450 determines or controls the extrusion amounts of the extrusion units 83 and 93. In the second embodiment, the extrusion amounts of the extrusion units 83 and 93 are as described above. The controller 450 determines whether or not the pushing parts 83 and 93 are pushed out toward the openings 80h and 90h.

In the present embodiment, a fifth detection unit for detecting the paper sheets stacked on the stacking units 80 and 90 and a sixth detection unit for detecting that the paper sheets are conveyed to the stacking units 80 and 90. And a detection unit. And when the detection result by a 5th detection part and the detection result by a 6th detection part satisfy | fill predetermined conditions, the extrusion parts 83 and 93 will be extruded toward opening part 80h, 90h.

In the present embodiment, the sensors 89 and 99 shown in FIG. 2 serve as a fifth detection unit, and the sensors S3-S5 serve as a sixth detection unit. If the sensor S3 detects that the paper sheet has passed but the sensor S4 does not detect that the paper sheet has passed, it is determined that the paper sheet has been stacked in the stacking unit 80, and the sensor S4 If it is detected that the paper sheet has passed but the sensor S5 does not detect that the paper sheet has passed, it is determined that the paper sheet has been stacked in the stacking unit 90.

The above-mentioned “predetermined condition” is that the sensors 89 and 99 detect that the sheets are conveyed to the stacking units 80 and 90 by the sensors S3 to S5. You may make it satisfy | fill when it detects that the leaf is not accumulate | stored.

More specifically, the sensor S3 detects that the paper sheet has passed, but the sensor S4 does not detect that the paper sheet has passed, and it is determined that the paper sheet has been conveyed to the stacking unit 80. Nevertheless, when the sensor 89 detects that the paper sheets are not stacked on the stacking unit 80 or when the sensor S4 detects that the paper sheets have passed, the sensor S5 detects the paper sheets. Even though it is not detected that the paper has passed and it is detected that the paper has been conveyed to the stacking unit 90, the sensor 99 detects that the paper is not stacked on the stacking unit 80. The “predetermined condition” may be satisfied.

Furthermore, the “predetermined condition” described above is further satisfied when the number of sheets detected as being conveyed to the stacking units 80 and 90 by the sensors S3 to S5 is equal to or less than the predetermined number. May be. More specifically, the sensor S3 detects that the paper sheet has passed, but the sensor S4 does not detect that the paper sheet has passed, and has detected that the paper sheet has been conveyed to the stacking unit 80. Nevertheless, the number of sheets detected by the sensor 89 that the sheets are not stacked on the stacking unit 80 and detected as being transported to the stacking unit 80 by the sensors S3 and S4. Or the sensor S4 detects that the paper sheet has passed, but the sensor S5 does not detect that the paper sheet has passed, and the paper sheet has been conveyed to the stacking unit 90. Despite the detection, the paper sheet detected by the sensor 99 that the paper sheets are not stacked on the stacking unit 80 and detected to have been transported to the stacking unit 90 by the sensors S4 and S5. The number of the class is less than the predetermined number In some cases, the "predetermined condition" may also be satisfied.

In the second embodiment, the other configurations are substantially the same as those in the first embodiment. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

Also in this embodiment, the same effects as in the first embodiment can be obtained. Since it has been described in detail in the first embodiment, the effects in this embodiment will be described while being omitted as appropriate.

According to the present embodiment, for example, when a part of the paper sheet (more specifically, a part of the banknote) is transparent, the paper sheet is also stacked on the stacking units 80 and 90. Regardless, it is possible to prevent the paper sheets from being determined not to be accumulated in the accumulation units 80 and 90.

That is, when a part of the paper sheet is transparent, the light emitted from the light emitting unit of the sensors 89 and 99 is transmitted through the transparent part (transparent part) like the clear window of the paper sheet. The light receiving unit may receive light (see FIGS. 18A and 18C). In this case, although the paper sheets are accumulated in the accumulating sections 80 and 90, it is determined from the information from the sensors 89 and 99 that the paper sheets are not accumulated in the accumulating sections 80 and 90. Will be.

In this respect, according to the present embodiment, when the detection results by the sensors 89 and 99 as the fifth detection unit and the detection results by the sensors S3 to S5 as the sixth detection unit satisfy a predetermined condition, the push-out unit 83 and 93 are pushed out toward the openings 80h and 90h. Even though the “predetermined condition” is detected by the sensors S3 to S5 that the sheets are conveyed to the stacking units 80 and 90, the sheets 89 and 99 are detected by the sensors 89 and 99. Is satisfied when it is detected that the sheets are not accumulated, the information from the sensors 89 and 99 is not used even though the sheets are actually accumulated in the accumulating sections 80 and 90. This applies when it is determined that the paper sheets are not stacked on the stacking units 80 and 90. When the “predetermined condition” is satisfied, the pushing portions 83 and 93 are pushed out toward the openings 80h and 90h, so that the positions of the sheets stacked in the collecting portions 80 and 90 are determined. The light emitted from the light emitting portions of the sensors 89 and 99 is irradiated to the portions other than the transparent portions (see FIGS. 18B and 18D). As a result, the sensors 89 and 99 can detect that the paper sheets are accumulated in the accumulating units 80 and 90. In addition, when the information from the sensors 89 and 99 is acquired in real time, the extrusion by the extrusion portions 83 and 93 is performed as a result of the extrusion portions 83 and 93 being pushed toward the openings 80h and 90h, for example. You may stop when the light irradiated from the light emission part 89,99 is interrupted | blocked.

Further, as described above, the “predetermined condition” is satisfied only when the number of sheets detected as being conveyed to the stacking units 80 and 90 by the sensors S3 to S5 is equal to or less than the predetermined number. You can also. In this case, the “predetermined number of sheets” refers to, for example, even if light from the light emitting portions of the sensors 89 and 99 is irradiated to a transparent portion of the paper sheet, the light is transparent to the paper sheet. The number is such that the portion does not pass through, for example, 5 to 10 sheets. Therefore, when this mode is adopted, the number of sheets conveyed to the stacking units 80 and 90 is equal to or less than a predetermined number, and the sheets 89 are sent to the stacking units 80 and 90 by the sensors 89 and 99. Only when it is not possible to detect that the paper has been accumulated, the push-out sections 83 and 93 push out the paper sheets, and the number of paper sheets conveyed to the stacking sections 80 and 90 is greater than the predetermined number. If the sensors 89 and 99 cannot detect that the paper sheets are stacked on the stacking units 80 and 90, it is detected that some trouble related to the sensors 89 and 99 has occurred. Become.
