Description

  The present invention relates to a sheet orientation detection device that detects a sheet that has been reversed when the folded or bound sheets are stacked with their orientations aligned.

  2. Description of the Related Art Conventionally, usage details of credit cards and mobile phones are printed on predetermined paper with usage details information, enclosed in an envelope, and sent to the user. In addition, in credit card companies and mobile phone companies that ship usage statements, a flyer on which advertisement information is posted is enclosed in an envelope together with the usage statement and sent to the user.

  Since the usage statement or leaflet enclosed in the envelope is larger than the envelope enclosed in this manner, it will be enclosed in the envelope in a folded state. When the information is taken out, it is necessary to align the orientations in order to make it easier to see the usage details printed on the usage statement and the advertising information posted on the flyer. In addition, in the usage specification, when the area on which the address information that is a part of the envelope is printed is displayed from the window portion of the envelope, the direction of the enclosed usage specification is used. If the address is not correct, the destination information cannot be displayed from the window portion of the envelope, and the usage statement cannot be delivered to the user.

  Also, in direct mail and business mail in which a plurality of printed materials on which advertisement information is posted are enclosed in an envelope, the orientation of the printed material is changed in order to make the advertisement information easier to see when the printed material is taken out from the envelope at the destination. Must be aligned.

  When a plurality of printed materials as described above are enclosed in one envelope, the plurality of printed materials to be enclosed are fed one by one from the feeder, sequentially overlapped, and sealed in the envelope. Therefore, the fed printed material is supplied in a folded state to each feeder that feeds the printed material one by one. In this case, the same type of printed matter is printed with information printed and folded, and then the plurality of printed materials are overlaid and supplied to the feeder. Since an inclination occurs, the images are superposed so that the directions thereof are alternated every predetermined number of sheets and supplied to the feeder. For this reason, the operator performs the work of aligning the orientation of the printed matter before the superimposed printed matter is actually applied to the feeder, thereby aligning the orientation of the printed matter enclosed in one envelope.

  However, as described above, in the case where the printed materials that are superimposed so that the orientations are staggered every predetermined number of sheets are aligned by an operator before being actually applied to the feeder, the work of aligning the orientation of the printed materials is not possible. Since this is a manual operation, there is a risk that printed materials that do not have the same orientation may exist. For this reason, when the orientation of the printed material is aligned, the operator visually confirms whether there is a printed material that does not have the correct orientation. There is a risk of it.

  The present invention has been made in view of the problems of the conventional techniques as described above, and when the folded or bound sheets are stacked with their orientations aligned, a sheet that is reversed is used. It is an object of the present invention to provide a paper orientation detection device that can detect without depending on human hands.

In order to achieve the above object, the present invention provides:
A plurality of paper pieces are overlapped, the first side is not open between the plurality of paper pieces, and the second side opposite to the first side is When a plurality of paper sheets in which at least some of the plurality of paper piece parts are opened are overlapped so as to have a predetermined orientation, the predetermined orientation is selected from the plurality of stacked paper sheets. A paper orientation detection device for detecting papers stacked in opposite directions so that the first side and the second side are opposite to each other,
The plurality of stacked sheets are accommodated so that the first side of the sheets stacked in a predetermined direction among the plurality of sheets is in contact with the bottom surface, and the plurality of sheets are stacked on the bottom surface. A paper storage section having a hole part of which each part is exposed;
An air blowing unit that blows air through the hole to a plurality of sheets stored in the sheet storage unit.

  In the present invention configured as described above, the plurality of stacked sheets are placed in the sheet storage portion so that the first side of the sheets stacked in a predetermined direction out of the plurality of sheets comes into contact with the bottom surface. In this state, when air is blown from the air blowing unit to a plurality of sheets through holes provided in the bottom surface of the sheet containing unit, air is blown on the sheets stacked in a predetermined direction. Since the side is a first side that is not open between the plurality of paper pieces constituting the paper, air does not pass through the front and back of the paper to the opposite side and is not lifted by the blown air . On the other hand, in the paper stacked in the direction opposite to the predetermined direction, the side on which the air is blown has a second side part in which at least a part of the paper pieces constituting the paper is open. Therefore, the blown air enters between the open paper pieces and hits the first side that is not open between the plurality of paper pieces, and is thereby lifted by the blown air.

  As a result, among the plurality of sheets stored in the sheet storage unit, only the sheets stacked in the direction opposite to the predetermined direction are lifted, and the folded or bound sheets are stacked in the same direction. In this case, it is possible to detect the paper that has been reversed.

  As described above, in the present invention, a plurality of paper pieces are overlapped, and the first side is not open between the plurality of paper pieces, and faces the first side. A first side of a sheet in which a plurality of sheets in which at least some of the plurality of paper pieces are open is overlapped in a predetermined direction among the plurality of sheets is a second side. For a plurality of sheets stored in the sheet storage section, and a sheet storage section that is accommodated so as to contact the bottom surface, and has a hole portion that exposes a part of each of the plurality of sheets on the bottom surface. When the air is blown to a plurality of sheets through the hole provided in the bottom surface of the sheet storage unit from the air spray unit, the sheet storage unit Out of a plurality of sheets stored in the Only superimposed sheets will be lifted, when superimposing the paper or stapled or folded by aligning its orientation, it is possible to detect the sheet became reversed without hands.

An end support surface 13 that supports one end of a plurality of sheets accommodated by one side surface 12, a surface orthogonal to the two side surfaces 12, and an end supported by the end support surfaces 13 of the plurality of accommodated sheets It is comprised from the edge part support shaft 14 which supports the other end which opposes. In addition, the placement surface on which the plurality of stacked sheets is placed is a part of the bottom surface 11 on the end support surface 13 side of the side that contacts the bottom surface 11 of the paper stored in the paper storage box 10. A region facing the surface is a hole 15 through which each of a plurality of stored sheets is exposed.

  The optical sensor 31 includes a pair of sensors, and detects whether an object is present between the pair of sensors based on whether the light emitted from one is received by the other. In the state in which the paper is stored, there is no paper between the sensors, and when the paper stored in the paper storage box 10 is lifted by the air blown from the air supply nozzle 22, the paper is present between the sensors. It is arranged in the position.

  The air supply nozzle 22 discharges air supplied from the air supply unit 21 and is disposed in a region facing the hole 15 of the paper storage box 10, thereby supplying from the air supply unit 21. The blown air is blown against the area of the paper storage box 10 where the hole 15 is provided. The sheet is accommodated in the direction in which the sheets stored in the sheet storage box 10 overlap while being opposed to the hole 15 by the support shaft 23. As shown in FIG. 2, the air supply nozzle 22 has a plurality of air outlets 24 at the tip, and the plurality of air outlets 24 are orthogonal to the stacking direction of the sheets stored in the sheet storage box 10. It is arranged in the direction to.

  Hereinafter, using the sheet orientation detection device 1 configured as described above, an operation for detecting a sheet superposed in a direction opposite to a predetermined direction from among a plurality of sheets superimposed in a predetermined direction. Will be described.

  First, a paper whose orientation can be detected by being housed in the paper storage box 10 of the paper orientation detection device 1 configured as described above will be described.

  3A and 3B are diagrams illustrating an example of a sheet whose orientation can be detected by being accommodated in the sheet storage box 10 of the sheet orientation detection apparatus 1 illustrated in FIG. 1. FIG. 3A is an external view, and FIG. It is a figure which shows a laminated structure.

  As the paper whose orientation can be detected by being stored in the paper storage box 10 of the paper orientation detection device 1 shown in FIG. 1, for example, as shown in FIG. 3, two paper pieces 41a are provided via a folding part 41c. , 41b, a paper piece 42 in which two paper pieces 42a, 42b are continuous via a folding part 42c, and two paper pieces 43a, 43b in succession through a folding part 43c. The leaflet 40 is formed by binding the paper pieces 43 to each other with the adhesive 44 at the folding portions 41c to 43c and binding them, and folding them at the folding portions 41c to 43c. This flyer 40 is configured by overlapping a plurality of paper pieces 41a, 41b, 42a, 42b, 43a, 43b with the above-described configuration, and the side on the folding portions 41c to 43c side is the first side. The paper pieces 41a, 41b, 42a, 42b, 43a, 43b are not opened, and the sides facing the folded portions 41c-43c of the paper pieces 41a, 41b, 42a, 42b, 43a, 43b are The second side portion serves as an opening between the paper pieces 41a, 41b, 42a, 42b, 43a, 43b.

  The flyer 40 configured in this way is a diagram in which the paper pieces 41 to 43 adhered to each other are folded at the folding portions 41c to 43c, respectively, and overlapped in a predetermined direction so that the respective folding portions 41c to 43c overlap. 1 is stored in the paper storage box 10 of the paper orientation detection device 1 shown in FIG.

  4 is a view showing an example of a state in which a leaflet having the configuration shown in FIG. 3 is stored in the paper storage box 10 of the paper orientation detection device 1 shown in FIG. b) is a view seen from the end support surface 13 side.

  As shown in FIG. 4, leaflets 40-1 to 40-8 having a configuration similar to that shown in FIG. 3 are overlapped in a predetermined direction and bound by the adhesives 44 on the side of the folded portions 41 c to 43 c. The sheet is accommodated in the sheet storage box 10 of the sheet orientation detection device 1 so that the portion comes into contact with the bottom surface 11. At this time, since the leaflets 40-1 to 40-8 do not exist between the pair of sensors constituting the optical sensor 31, the leaflets 40-1 to 40-8 are not detected in the optical sensor 31. It has become. In this example, in order to simplify the explanation, a case where eight leaflets 40-1 to 40-8 are overlapped and accommodated in the paper storage box 10 of the paper orientation detection device 1 will be described as an example. However, actually, more leaflets than this are superimposed and accommodated in the paper storage box 10 of the paper orientation detection device 1.

  Next, when the leaflets 40-1 to 40-8 superimposed in a predetermined direction as described above are detected in the state in which the leaflets 40-1 to 40-8 are accommodated in the paper storage box 10 of the paper orientation detection device 1, Will be described.

  FIG. 5 illustrates an operation when detecting a leaflet that is superimposed in the reverse direction from among leaflets that are stacked and stored in a predetermined direction in the sheet storage box 10 of the sheet orientation detection device 1 illustrated in FIG. 1. (A) is a figure which shows the state by which air was sprayed from the air supply nozzle 22 with respect to the leaflet piled up by the predetermined direction, (b) is with respect to the leaflet piled up in reverse direction It is a figure which shows the state by which air was sprayed from the air supply nozzle. In this example, eight leaflets 40-1 to 40-8 having the same configuration as that shown in FIG. 3 are overlaid, and of these, leaflets 40-1 to 40-3, 40-5 to 40. It is assumed that −8 is overlaid in a predetermined direction and only the leaflet 40-4 is overlaid in the opposite direction.

  Folded portions 41c to 43c of the leaflets 40-1 to 40-3 and 40-5 to 40-8 in which the eight leaflets 40-1 to 40-8 are overlapped in a predetermined direction in a state where they are overlapped. When the air supply unit 21 and the air supply nozzle 22, which are air blowing units, are driven in the paper storage box 10 of the paper orientation detection device 1 so that the side portion on the side contacts the bottom surface 11, the air supply unit 21 Air is sent to the air supply nozzle 22 and discharged from the air outlet 24 of the air supply nozzle 22, and the air supply nozzle 22 is moved from one side of the two side surfaces 12 to the other side by the support shaft 23. Start moving.

  Since the air supply nozzle 22 is arranged in a region facing the hole 15 of the paper storage box 10, the air supplied from the air supply device 21 is in the region where the hole 15 of the paper storage box 10 is provided. However, since the leaflets 40-1 to 40-8 accommodated in the paper storage box 10 are exposed in the hole portion 15, the air supplied from the air supply device 21 passes through the hole portion 15. It is sprayed on flyers 40-1 to 40-8. In addition, the air supply nozzle 22 is arranged on one side of the two side surfaces 12 as an initial state, and a plurality of air outlets 24 constituting the air supply nozzle 22 are accommodated in the paper storage box 10. Since the flyers 40-1 to 40-8 are arranged in a direction orthogonal to the overlapping direction of the flyers 40-1 to 40-8, the air discharged from the air supply nozzle 22 is sent to the flyers 40-1 to 40-40 stored in the paper storage box 10. −8, first, the leaflet 40-1 in contact with one side surface 12 is blown, and then the leaflets 40-2 to 40-8 are blown one by one as the air supply nozzle 22 moves. It will be.

  When the air discharged from the air supply nozzle 22 is blown to the leaflets 40-1 stacked in a predetermined direction among the leaflets 40-1 to 40-8 accommodated in the paper storage box 10, FIG. ), The air blown by the air supply nozzle 22 is not open between the plurality of paper pieces 41a, 41b, 42a, 42b, 43a, 43b. The leaflet 40-1 is not lifted by the air blown from the air supply nozzle 22 by passing through the front and back of the leaflet 40-1 to the opposite side of the bottom surface 11. The same applies to the leaflets 40-2, 40-3, 40-5 to 40-8 that are superimposed in a predetermined direction.

  On the other hand, in the leaflet 40-4 superimposed in the direction opposite to the predetermined direction, as shown in FIG. 5B, the side to which air is blown by the air supply nozzle 22 is a plurality of paper pieces 41a, 41b, 42a. , 42b, 43a, 43b are opened, so that the air blown by the air supply nozzle 22 enters between the opened paper pieces 41a, 41b, 42a, 42b, 43a, 43b. Thus, the folded portion 43c and the paper pieces 41 to 43 abut against the portion where the adhesive 44 is adhered, and thereby the flyer 40-4 is lifted by the air blown from the air supply nozzle 22.

  FIG. 6 is a view showing a state in which the leaflet 40-4 is lifted by the air blown from the air supply nozzle 22 in the sheet orientation detection device 1 shown in FIG. ) Is a view seen from the side 12 side.

  In the sheet orientation detection device 1 shown in FIG. 1, of the bottom surface 11, the side portion on the side of the end support surface 13 that contacts the bottom surface 11 of the leaflets 40-1 to 40-8 accommodated in the sheet storage box 10. Since the region facing the part is the hole 15 where each of the accommodated leaflets 40-1 to 40-8 is exposed, the leaflets 40-1 to 40-8 accommodated in the paper storage box 10 are provided. Air is blown from the air supply nozzle 22 to the end support surface 13 side of the side portion that comes into contact with the bottom surface 11, and as a result, as shown in FIG. 6, the end support surface 13 of the leaflet 40-4. The side will be lifted. At this time, the end portion opposite to the end portion on which the flyer 40-4 is lifted is supported by the end portion support shaft 14 provided in the paper storage box 10, but the bottom surface 11 of the end portion support shaft 14 is supported. When the air is blown to the end support surface 13 side of the leaflet 40-4, the end support surface 13 side of the leaflet 40-4 is used as a fulcrum when air is blown to the end support surface 13 side of the leaflet 40-4. Can be lifted easily. Further, among the leaflets 40-1 to 40-8 accommodated in the paper storage box 10, when the leaflets 40-1 and 40-8 that contact the side surface 12 are superimposed in the opposite direction, the leaflet 40- on the side surface 12 is used. If the friction coefficient of the surface in contact with 1, 40-8 is large, even if air is blown from the air supply nozzle 22 to the leaflets 40-1, 40-8, the end support surfaces 13 of the leaflets 40-1, 40-8. The side will be difficult to lift. Therefore, it is preferable to use a member having a small friction coefficient as the member constituting the side surface 12. Further, when the friction coefficient of the member constituting the side surface 12 is large, a paper material or the like having a small friction coefficient is attached to the surface of the side surface 12 that contacts the leaflets 40-1 and 40-8 with an adhesive or a hook-and-loop fastener. It is preferable.

  When the leaflet 40-4 is lifted by the air blown from the air supply nozzle 22 in this way, the light emitted from one of the pair of sensors constituting the optical sensor 31 is blocked by the leaflet 40-4, and the other The sensor no longer receives light.

  Then, the controller 33 is notified of this, the patrol light 32 is turned on by the control of the controller 33, and the flyers 40-1 to 40-8 accommodated in the paper storage box 10 have the opposite direction. The leaflet 40-4 lifted from the paper storage box 10 is once extracted from the paper storage box 10 to be in the correct orientation, and the flyers 40-1 to 40-3, Returned to 40-5 to 40-8.

  In the embodiment described above, the folding portion 41c as shown in FIG. 3 is used as a paper whose orientation can be detected by being stored in the paper storage box 10 of the paper orientation detecting device 1 shown in FIG. A paper piece 41 in which two paper pieces 41a and 41b are continuous via a paper sheet, a paper piece 42 in which two paper pieces 42a and 42b are continuous via a folding part 42c, and two paper pieces via a folding part 43c. An example of a leaflet 40 in which a piece of paper 43 formed by continuous portions 43a and 43b is bonded and bound to each other by an adhesive 44 at folding portions 41c to 43c and is folded at folding portions 41c to 43c. However, it may be a sheet that is simply folded at the folding portion. Examples of such paper are shown below.

  FIG. 7 is a view showing another example of paper whose orientation can be detected by being stored in the paper storage box 10 of the paper orientation detecting device 1 shown in FIG. 1, wherein (a) is an external view, (b) ) Is a diagram showing a laminated structure.

  As the paper whose orientation can be detected by being stored in the paper storage box 10 of the paper orientation detection device 1 shown in FIG. 1, there are three types of paper other than those shown in FIG. 3, for example, as shown in FIG. A leaflet 140 in which the paper pieces 141 to 143 are continuously configured through the folding portions 144a and 144b is exemplified. The leaflet 140 is formed by folding three folding pieces 144a and 144b so that three paper pieces 141 to 143 are overlapped, and the side on the folding portion 144a side becomes the first side and the piece of paper 141 ˜143 is not open, and the side of the paper piece 141 facing the folding part 144a and the side of the folding part 144b become the second side, and the space between the paper piece 141 and the paper pieces 142, 143 is between It is open.

  The flyer 140 configured in this manner is folded at the folding portions 144a and 144b, and is stacked in a predetermined direction so that the folding portions 144a and 144b are overlapped, and the paper of the paper orientation detection device 1 shown in FIG. It will be accommodated in the storage box 10.

  FIG. 8 is a diagram showing an example of a state in which a leaflet having the configuration shown in FIG. 7 is stored in the paper storage box 10 of the paper orientation detection device 1 shown in FIG. 1, as viewed from the end support surface 13 side. It is a figure.

  As shown in FIG. 8, leaflets 140-1 to 140-8 having the same configuration as that shown in FIG. 7 are stacked in a predetermined direction so that the side portion on the folding portion 144 a side contacts the bottom surface 11. It is stored in the paper storage box 10 of the paper orientation detection device 1. At this time, since the leaflets 140-1 to 140-8 do not exist between the pair of sensors constituting the optical sensor 31, the leaflets 140-1 to 140-8 are not detected in the optical sensor 31. It has become. In this example as well, in order to simplify the description, a case where eight leaflets 140-1 to 140-8 are overlapped and stored in the paper storage box 10 of the paper orientation detection device 1 will be described as an example. However, actually, more leaflets than this are superimposed and accommodated in the paper storage box 10 of the paper orientation detection device 1.

  In the following, when the leaflets 140-1 to 140-8 superimposed in a predetermined direction as described above are detected in the state in which the leaflets 140-1 to 140-8 are accommodated in the paper storage box 10 of the paper orientation detection device 1, Will be described.

  FIG. 9 illustrates an operation when a leaflet stacked in the opposite direction is detected from leaflets that are stacked and stored in a predetermined direction in the sheet storage box 10 of the sheet orientation detection device 1 shown in FIG. (A) is a figure which shows the state by which air was sprayed from the air supply nozzle 22 with respect to the leaflet piled up by the predetermined direction, (b) is with respect to the leaflet piled up in reverse direction It is a figure which shows the state by which air was sprayed from the air supply nozzle. In this example, eight leaflets 140-1 to 140-8 having the same configuration as that shown in FIG. 7 are overlaid, and of these, leaflets 140-1 to 140-3, 140-5 to 140. It is assumed that −8 is overlaid in a predetermined direction and only the leaflet 140-4 is overlaid in the opposite direction.

  Eight leaflets 140-1 to 140-8 are placed on the folding portion 141a side of the leaflets 140-1 to 140-3 and 140-5 to 140-8 that are overlapped in a predetermined direction in a state where they are overlapped. When the air supply unit 21 and the air supply nozzle 22, which are air blowing parts, are driven in the paper storage box 10 of the paper orientation detection device 1 so that the side part is in contact with the bottom surface 11, the air supply unit 21 supplies air. Air is sent to the nozzle 22 and discharged from the air outlet 24 of the air supply nozzle 22, and the air supply nozzle 22 moves from one side of the two side surfaces 12 to the other side by the support shaft 23. Start.

  Since the air supply nozzle 22 is arranged in a region facing the hole 15 of the paper storage box 10, the air supplied from the air supply device 21 is in the region where the hole 15 of the paper storage box 10 is provided. However, since the leaflets 140-1 to 140-8 accommodated in the paper storage box 10 are exposed in the hole portion 15, the air supplied from the air supply device 21 passes through the hole portion 15. It is sprayed on flyers 140-1 to 140-8. In addition, the air supply nozzle 22 is arranged on one side of the two side surfaces 12 as an initial state, and a plurality of air outlets 24 constituting the air supply nozzle 22 are accommodated in the paper storage box 10. Since the flyers 140-1 to 140-8 arranged in the direction orthogonal to the overlapping direction of the flyers 140-1 to 140-8, the air discharged from the air supply nozzle 22 is sent to the flyers 140-1 to 140-140 accommodated in the paper storage box 10. −8, first, it is blown to the leaflet 140-1 that is in contact with one side surface 12, and then blown to the leaflets 140-2 to 140-8 one by one as the air supply nozzle 22 moves. It will be.

  When the air discharged from the air supply nozzle 22 is blown to the leaflet 140-1 superimposed in a predetermined direction among the leaflets 140-1 to 140-8 housed in the paper storage box 10, FIG. ), The air blown by the air supply nozzle 22 passes through the front and back of the flyer 140-1 because the air blown by the air supply nozzle 22 is not open between the plurality of paper pieces 141-143. Therefore, the leaflet 140-1 is not lifted by the air blown from the air supply nozzle 22 due to slipping out to the side opposite to the bottom surface 11. The same applies to leaflets 140-2, 140-3, 140-5 to 140-8 that are superimposed in a predetermined direction.

  On the other hand, in the leaflet 140-4 superimposed in the direction opposite to the predetermined direction, as shown in FIG. 9B, the side to which air is blown by the air supply nozzle 22 is the paper piece portion 141 and the paper piece portions 142, 143. The air blown by the air supply nozzle 22 enters between the opened paper piece portion 141 and the paper piece portion 143, hits the folding portion 144a, and thereby, The leaflet 140-4 is lifted by the air blown from the air supply nozzle 22.

  The flyer 140-4 lifted in this way is lifted on the end support surface 13 side in the same manner as shown in FIG. 6, and this is detected by the optical sensor 31 and is superimposed in a direction opposite to the predetermined direction. It will be detected.

  In this embodiment, flyers that are superimposed on each other and accommodated in the paper storage box 10 are supported by being sandwiched and supported by the two side surfaces 12 of the paper storage box 10 in the overlapping direction. When the thickness is smaller than the distance between the two side surfaces 12, one side of the overlapped leaflet is supported by one of the two side surfaces 12, and the other surface is movable separately prepared from the side surface 12. It is also conceivable to use a structure that is supported by a support member. In that case, when the region on the side of the end support shaft 14 is supported by the support member on the surface opposite to the side surface 12 of the stacked leaflets, the support member is moved when air is blown from the air supply nozzle 22. As a fulcrum, the end support surface 13 side of the leaflet can be easily lifted.

  Further, in this embodiment, as shown in FIG. 2, the air supply nozzle 22 has a plurality of air outlets 24 arranged in a direction orthogonal to the overlapping direction of the leaflets stored in the paper storage box 10 at the tip. However, it may have only one longitudinal outlet that has a longitudinal direction in the direction perpendicular to the direction in which the leaflets accommodated in the paper storage box 10 are superposed. The shape may not be a longitudinal shape. However, a direction in which a plurality of air outlets 24 are arranged in a direction orthogonal to the overlapping direction of the leaflets stored in the paper storage box 10 or a direction orthogonal to the overlapping direction of the leaflets stored in the paper storage box 10 If the air outlet has only one longitudinal outlet, the air can be sequentially sprayed with a lot of air in a spot-by-spot manner in parallel with the leaflet housed in the paper storage box 10. Therefore, the flyer can be easily lifted by the air blown from the air supply nozzle 22.

  Further, in this embodiment, the air supply nozzle 22 that blows air through the hole portion 15 of the paper storage box 10 to the leaflet stored in the paper storage box 10 is formed by the support shaft 23 in the direction in which the leaflet is superimposed. The air supply nozzle 22 is fixed and the paper storage box 10 is moved in the overlapping direction of the leaflet so that the relative position between the air supply nozzle 22 and the paper storage box 10 is changed. It is also conceivable to change the leaflet to which the air discharged from the air supply nozzle 22 is blown. It is also conceivable that the air supply nozzle 22 and the paper storage box 10 are fixed, and the air supply nozzle 22 is configured to blow air at once to the entire hole 15 of the paper storage box 10.

  Further, the paper whose orientation is detected by the paper orientation detection device 1 shown in FIG. 1 is not limited to the leaflet having the configuration shown in FIG. 3 or 7, and is configured by overlapping a plurality of paper pieces. The first side is not open between the plurality of paper pieces, and the second side opposite to the first side is between at least some of the plurality of paper pieces. Is open, for example, the first side is stapled, or the second side has a fold, and the length of the piece of paper that is folded at the fold is short. Various things, such as a thing, can be applied. For example, a plurality of holes having a small diameter such as a marginal punch may be formed in the first side portion or other side portions. In addition, the two sides adjacent to the first side where the plurality of paper pieces are not opened are envelope-like ones where the plurality of paper pieces are not opened, or the second side portions are not opened between the plurality of paper pieces. Even when one side adjacent to one side is not open between a plurality of paper pieces, the direction can be detected by the paper orientation detection device 1 shown in FIG.
