Hereinafter, embodiments of the binding medium pressing device and the binding medium reading device disclosed in the present application will be described in detail with reference to the drawings. The binding medium pressing device and the binding medium reading device disclosed in the present application are not limited by the following embodiments.

FIG. 1 is a perspective view showing a binding medium pressing device according to the first embodiment. FIG. 2A is a perspective view illustrating a state in which the presser of the binding medium pressing device according to the first embodiment is bent into a V shape. FIG. 2B is a perspective view illustrating a state in which the presser of the binding medium pressing device according to the first embodiment is developed in a flat shape.

As shown in FIG. 1, the binding medium pressing device 7 according to the first embodiment includes a mounting table 8 on which the binding medium 5 is mounted with the spread surface 5 a facing upward, and a binding table mounted on the mounting table 8. And a presser 11 as a pressing member that presses the spread surface 5a of the medium 5 toward the mounting table 8 side.

The mounting table 8 has a set of mounting plates 9 on which both sides of the spread surface 5 a of the binding medium 5 are mounted, and the set of mounting plates 9 are mounted on the mounting table 8. The binding portions 5b of the binding medium 5 are arranged at a predetermined interval at which insertion is possible. The mounting plate 9 is supported by a plurality of elastic members 13 such as coil springs provided on the support base 12 so as to be elastically displaceable in the height direction. Further, the set of mounting plates 9 are provided so as to be independently displaceable in the height direction, and the page thicknesses on both sides of the spread surface 5a of the binding medium 5 mounted on the mounting table 8 are set. By absorbing this difference, both sides of the spread surface 5a are configured to have the same height.

Further, the binding medium pressing device 7 according to the first embodiment is configured to be able to be switched between the flat mounting table 8 and the V-shaped mounting table 8 according to the thickness of the binding medium 5 to be read. Has been. For example, when the binding medium 5 having a large number of pages and a large thickness is read, the V-shaped mounting table 8 is selected in order to suppress the deflection generated on the spread surface 5a.

As shown in FIG. 2A and FIG. 2B, the presser 11 includes a pair of pressing plates 15 that press the spread surface 5a and a plurality of one end portions of the pair of pressing plates 15 that can be bent along the one end portion. Connecting member 16. The pressing plate 15 is formed in a rectangular shape using, for example, a light transmissive glass material, a resin material, or the like, and both sides of one end portion are connected by a connecting member 16. The connecting member 16 is disposed on the outer peripheral side of the pressing plate 15 so as not to overlap the spread surface 5 a pressed by the pressing plate 15.

The connecting member 16 is fixed to the pressing plate 15 by a fixing member 17. In the first embodiment, a hinge is used as the connecting member 16, and a fixing screw or an adhesive is used as the fixing member 17, for example. The hinge has a rotating shaft, and the pair of pressing plates 15 are connected so that the rotating shaft is parallel to the extending direction of one end portion of each pressing plate 15 to be bent.

In Example 1, the connecting mechanism including the connecting member 16 and the fixing member 17 that connect the ends of the pair of pressing plates 15 so as to be bendable corresponds to the pressing mechanism in the present invention. The presser 11 has a connecting mechanism as a pressing mechanism, so that after pressing the binding portion region 5c from the binding portion region 5c corresponding to the binding portion 5b of the binding medium 5 in the spread surface 5a, It is possible to continuously press areas other than the binding area 5c in a direction away from the binding area 5c.

(Pressing operation in Example 1)
3A, 3B, and 3C are schematic diagrams for explaining an operation of pressing the spread surface 5a of the binding medium 5 placed on the flat mounting table 8 in the binding medium pressing device 7 of the first embodiment. FIG.

As shown in FIG. 3A, the binding medium 5 has the binding portions 5 b inserted between the mounting plates 9 of the mounting table 8, and both sides of the spread surface 5 a are mounted on the flat mounting table 8. It is placed across the plate 9. Next, the presser 11 is a binding medium on the mounting table 8 having a V-shaped tip in a state where each end of the pair of pressing plates 15 is bent in a V-shape so as to form a predetermined acute angle. 5 is spread toward the valley of the binding area 5c of the spread surface 5a. At this time, the extending direction of each end of the pair of bent pressing plates 15 is lowered in a state parallel to the horizontal direction. And as shown in FIG. 3B, the front end of the presser 11 bent so that each one end portion is formed in a V shape is in the valley of the binding portion region 5c of the spread surface 5a along the extending direction of the binding portion 5b. Pressed evenly. Thereby, the binding part area | region 5c of the facing surface 5a is pressed by the front-end | tip of the presser 11 bent in V shape, and a bending | flexion is corrected.

Subsequently, the pair of pressing plates 15 extends along the spread direction so as to follow the flat mounting table 8 while maintaining the state in which the tip of the presser 11 bent into a V shape presses the binding portion region 5c. And gradually expands into a flat shape. Finally, as shown in FIG. 3C, the presser 11 presses the entire spread surface 5 a of the binding medium 5 by developing a set of pressing plates 15 in a flat shape.

Further, when the spread surface 5 a is pressed by the presser 11, the set of mounting plates 9 that support both sides of the spread surface 5 a of the binding medium 5 is lowered by the elastic member 13 being elastically deformed by the pressing force of the presser 11. Is done. At this time, the pair of mounting plates 9 can appropriately support both sides having different thicknesses in the spread surface 5a by being independently displaced according to the thicknesses on both sides of the spread surface 5a. Therefore, even if the thickness of the both sides of the spread surface 5a changes with the turning of the page of the binding medium 5, the set of placement plates 9 can press both sides of the spread surface 5a appropriately. It is possible.

In this way, the presser 11 does not press the entire spread surface 5a of the binding medium 5 at a time, but first starts pressing from the binding portion region 5c of the spread surface 5a, and then spreads to the end in the spread direction. The area other than the binding area 5c is continuously pressed along the surface 5a. When the front end of the presser 11 bent in a V shape presses the binding portion region 5c, the spread surface 5a of the binding medium 5 is not restrained by the pressing plate 15 except for the binding portion region 5c. A space that can move freely is maintained. For this reason, the medium of the binding portion region 5c pressed by the one end portion of the pressing plate 15 is suppressed from moving toward the center of the valley of the binding portion region 5c in the spread direction of the spread surface 5a. It moves from the valley side toward the end side in the spread direction. As a result, when the binding portion area 5c is pressed by the presser 11, the vicinity of the binding portion area 5c is crushed so that an overlapping portion where the binding portion area 5c partially overlaps is suppressed, and the binding portion area 5c is suppressed. It becomes possible to press appropriately along the spread surface 5a.

4A, 4B, and 4C are schematic diagrams for explaining an operation of pressing the spread surface 5a of the binding medium 5 placed on the V-shaped placement table 8 in the binding medium pressing device 7 of the first embodiment. FIG.

When the binding medium 5 is mounted on the V-shaped mounting table 8, as shown in FIG. 4A, the binding medium 5 is mounted on each mounting table 8 as in the case where the flat mounting table 8 is used. The binding portion 5b is inserted between the placement plates 9, and both sides of the spread surface 5a are placed across the placement plates 9 of the V-shaped placement table 8. Next, in a state where each end portion of the pair of pressing plates 15 is bent into a V shape, the V-shaped tip of the presser 11 is a binding portion of the spread surface 5 a of the binding medium 5 on the mounting table 8. It is lowered toward the valley of the region 5c. At this time, the extending direction of each end of the pair of bent pressing plates 15 is lowered in a state parallel to the horizontal direction. As shown in FIG. 4B, the tip of the presser 11 bent into a V shape is pressed evenly along the extending direction of the binding portion 5b against the valley of the binding portion region 5c of the spread surface 5a. Thereby, the binding part area | region 5c of the facing surface 5a is pressed by the front-end | tip of the presser 11 bent in V shape, and a bending | flexion is corrected.

Subsequently, while maintaining the state in which the front end of the presser 11 bent into a V-shape presses the binding portion region 5c, the pair of pressing plates 15 has a spread direction so that the angle formed by each one end portion gradually increases. Gradually expands along. Finally, as shown in FIG. 4C, the presser 11 presses the entire spread surface 5 a of the binding medium 5 by deforming the pair of pressing plates 15 into a shape along the V-shaped mounting table 8. .

Further, when the spread surface 5 a is pressed by the presser 11, the set of mounting plates 9 that support both sides of the spread surface 5 a of the binding medium 5 is lowered by the elastic member 13 being elastically deformed by the pressing force of the presser 11. Is done. At this time, the pair of mounting plates 9 can appropriately support both sides having different thicknesses in the spread surface 5a by being independently displaced according to the thicknesses on both sides of the spread surface 5a. Therefore, even when the thickness of both sides of the spread surface 5a placed on the set of placement plates 9 varies as the pages of the binding medium 5 are turned, the presser 11 causes the spread surface 5a to It is possible to press both sides appropriately.

Thus, even when the presser 11 presses the binding medium 5 mounted on the V-shaped mounting table 8, the presser 11 does not press the entire spread surface 5a at once, but first binds the spread surface 5a. The pressing is started from the part area 5c, and then the parts other than the binding part area 5c are continuously pressed along the spread surface 5a. As a result, when the binding portion area 5c is pressed by the presser 11, the vicinity of the binding portion area 5c is crushed so that an overlapping portion where the binding portion area 5c partially overlaps is suppressed, and the binding portion area 5c is suppressed. It becomes possible to press appropriately along the spread surface 5a.

The presser 11 in the binding medium pressing device 7 according to the first embodiment starts pressing from the binding portion area 5c corresponding to the binding portion 5b of the binding medium 5 on the spread surface 5a, presses the binding portion area 5c, and then binds. The connecting member 16 is provided as a pressing mechanism for continuously pressing an area other than the binding area 5c in a direction away from the area 5c. Thereby, when the spread surface 5a is pressed by the presser 11, it is possible to suppress the occurrence of an overlapping portion in the binding portion region 5c of the spread surface 5a. As a result, the entire spread surface 5a including the binding portion region 5c of the spread surface 5a can be properly read, and damage to the spread surface 5a can be avoided.

Further, according to the first embodiment, the spread surface 5a can be obtained without performing a pressing operation requiring skill such as pressing with a flat presser while correcting the deflection of the binding portion region 5c of the spread surface 5a manually. Can be corrected easily and promptly.

Hereinafter, other embodiments will be described with reference to the drawings.

By treating the presser 21 of the second embodiment in the same manner as the presser 11 of the first embodiment, the pressing starts from the binding portion region 5c of the spread surface 5a, and after pressing the binding portion region 5c, from the binding portion region 5c. A region other than the binding portion region 5c is continuously pressed toward the direction of separation.

According to the presser 21 in the second embodiment, the pair of pressing plates 15 are connected by the connecting member 26 via the frame 22, so that the fixing structure for fixing the connecting member 26 applies a load to the pressing plate 15. It is possible to suppress the application. Therefore, in Example 2, the degree of freedom of the fixing structure of the connecting member 26 that connects the pair of pressing plates 15 is increased, and the mechanical strength of the presser 21 can be increased.

As shown in FIGS. 6A and 6B, the presser 31 in the third embodiment includes a connecting member 36 that connects a pair of frames 22 that support the pressing plates 15. An annular ring member is used as the connecting member 36. The frame 22 is provided with through-holes 38 through which ring members are inserted at both ends located on both sides of one end of the pressing plate 15. The ring member is provided so as to straddle the through hole 38 of the pair of frames 22, and is arranged so that the central axis of the ring member is parallel to the extending direction of one end of the pair of pressing plates 15. Yes.

Also in the third embodiment, as in the second embodiment, the set of pressing plates 15 is connected by the connecting member 36 via the frame 22, thereby fixing the connecting member 36 that connects the set of pressing plates 15. The degree of freedom of structure is increased, and the mechanical strength of the presser 31 can be increased.

Also in the third embodiment, similarly to the first embodiment, the presser 31 starts pressing from the binding portion region 5c of the spread surface 5a, and after pressing the binding portion region 5c, the end portion in the spread direction of the spread surface 5a. Can be continuously pressed. Accordingly, it is possible to suppress the occurrence of an overlapping portion in the binding area 5c of the spread surface 5a when the spreader 31 is pressed by the presser 31, and the entire spread surface 5a can be appropriately read.

FIG. 7A is a perspective view illustrating a state in which the presser of the binding medium pressing device according to the fourth embodiment is bent into a V shape. FIG. 7B is a perspective view illustrating a state in which the presser of the binding medium pressing device according to the fourth embodiment is developed in a flat shape.

7A and 7B, the presser 41 of the fourth embodiment includes a connecting member 46 that connects a pair of frames 22 that support the pressing plates 15. In the set of frames 22, side surfaces of both end portions located on both sides of one end portion of the pressing plate 15 are connected by a connecting member 46. The connecting member 46 is fixed to the frame 22 by a fixing member 47. A plate-like link member is used as the connecting member 46, and a fastening member such as a fixing screw is used as the fixing member 47.

Also in the fourth embodiment, as in the second embodiment, the set of pressing plates 15 is connected by the connecting member 46 via the frame 22, thereby fixing the connecting member 46 that connects the set of pressing plates 15. The degree of freedom of structure is increased, and the mechanical strength of the presser 41 can be increased.

Also in the fourth embodiment, similarly to the first embodiment, the presser 41 starts pressing from the binding portion region 5c of the spread surface 5a, and after pressing the binding portion region 5c, the end portion in the spread direction of the spread surface 5a. Can be continuously pressed. Thereby, it becomes possible to suppress the occurrence of an overlapping portion in the binding portion region 5c of the spread surface 5a when the spread surface 5a is pressed by the presser 41, and the entire spread surface 5a can be read appropriately.

Here, the shape of the tip of the presser 11 (21, 31, 41) that is bent into a V shape in the first to fourth embodiments will be described. FIG. 8A is a cross-sectional view for explaining the shape of one end of the pair of pressing plates 15 for the presser 11 (21, 31, 41) in the embodiment. FIG. 8B is a cross-sectional view for explaining the shape of one end of the pair of pressing plates 15 for the presser 11 (21, 31, 41) in the embodiment.

As shown in FIG. 8A and FIG. 8B, one end of the pair of pressing plates 15 is tapered toward the corner on the side in contact with the binding area 5c, so-called tapered. That is, one end portion of the pair of pressing plates 15 is formed in a tapered shape toward the corner on the pressing surface side by notching a corner portion on the back surface side of the pressing surface in contact with the spread surface 5a. . The angle formed by one end of each pressing plate 15 is, for example, an angle of about ½ of a desired acute angle when the presser 11 (21, 31, 41) is bent into a V shape.

By forming one end of the pair of pressing plates 15 as described above, when the presser 11 (21, 31, 41) is bent into a V shape, each end of the pair of pressing plates 15 is It is possible to suppress gaps between them. Thereby, when each one end part of the set of pressing plates 15 bent in a V shape is pressed against the binding part region 5c, the corner part in the thickness direction of the one end part of the pressing plate 15 is the binding part region 5c. It is suppressed from being pressed against the inner wall of the valley, and the inner wall of the valley of the binding portion region 5c is pressed by the pressing surface of the pressing plate 15 that continuously contacts the spread surface 5a. For this reason, it becomes possible to press the binding part area | region 5c further appropriately, and it can further suppress that an overlap part arises in the binding part area | region 5c.

Although not shown in the drawings, the presser may have another structure for suppressing the generation of a gap between the one end portions of the pair of pressing plates 15 when bent into a V shape. The presser may have, for example, a zigzag meshing structure such that each end portion of the set of pressing plates 15 is bent while meshing with each other along the extending direction of the one end portion.

In addition, although not shown in the drawing, the angle regulating piece for regulating the angle formed by the tip of the presser so that each one end of the set of pressing plates 15 forms a predetermined acute angle when the presser is bent is a set of pressing plates. May be provided. For example, when the tip of the presser has a predetermined acute angle, the angle restricting pieces of the pair of pressing plates 15 abut each other, thereby regulating the angle of the tip of the presser, and the tip becomes smaller than the predetermined angle. The angle formed by the tip can be appropriately secured.

In Examples 5 to 9 below, each end of the pair of pressing plates 15 may be formed in the shape shown in FIGS. 8A and 8B.

FIG. 9A is a perspective view illustrating a state in which the presser of the binding medium pressing device according to the fifth embodiment is bent into a V shape. FIG. 9B is a perspective view illustrating a state in which the presser of the binding medium pressing device according to the fifth embodiment is developed in a flat shape. The presser according to the fifth embodiment is different from the first embodiment in that it includes a guide frame that guides the bending operation of the pair of pressing plates 15.

As shown in FIGS. 9A and 9B, a presser 51 as a pressing member has a V-shape (bent state) in which a set of pressing plates 15 is bent along one end, and a set of pressing plates 15 is the same. A guide frame 52 is provided as a guide member that is movably guided in a flat shape (flat state) located on the surface.

The set of pressing plates 15 is formed in a rectangular shape by, for example, a light transmissive glass material, a resin material, or the like, and one end portion thereof is disposed adjacently. A plurality of guide shafts 53 that are movably supported by a guide frame 52 are provided on the outer peripheral portion of the pressing plate 15. The guide shaft 53 has both sides at both ends in the direction in which the pair of pressing plates 15 are bent, that is, both sides at one end on the side where the pair of pressing plates 15 are bent in a V shape, and the other side opposite to the one end. It is fixed on both sides at the end.

The guide frame 52 is formed in a frame shape that supports the outer peripheral side of the set of pressing plates 15, and a set of guide plates 52 a that supports both sides of one end portion on the side where the set of pressing plates 15 are bent. And a connecting plate 52b for connecting a pair of guide plates 52a. Further, the guide frame 52 has an upper opening 52 c that allows the spread surface 5 a to be read through the pair of pressing plates 15, and the binding medium 5 placed on the placing table 8 can enter the guide frame 52. A lower opening 52d.

In addition, the guide frame 52 is capable of moving a pair of pressing plates 15 in a horizontal direction A, and a first guide slit 54a, and the pair of pressing plates 15 is movable in a vertical direction B. And a second guide slit 54b for guiding the first guide slit. The first guide slit 54 a and the second guide slit 54 b are formed so that each end of the bent pressing plate 15 presses the valley of the binding area 5 c in the binding medium 5 on the mounting table 8. Each guide frame 52 is formed at a predetermined position so as to form a suitable predetermined acute angle.

(Pressing operation in Example 5)
The presser 51 moves along the first guide slit 54a while the pair of pressing plates 15 moves down along the second guide slit 54b by its own weight. For this reason, in the initial state, as shown in FIG. 9A, the presser 51 is in a state where each end of the pair of pressing plates 15 is naturally bent so as to form a V shape. The user lowers the presser 51 toward the spread surface 5 a of the binding medium 5 placed on the placing table 8 in a state where the pair of pressing plates 15 are bent in a V shape. At this time, the presser 51 is lowered while the V-shaped tip formed by one end of the pair of pressing plates 15 is opposed to the valley of the binding portion region 5c of the spread surface 5a, thereby binding by the V-shaped tip. The partial area 5c is pressed.

Subsequently, the presser 51 is gradually lowered toward the spread surface 5 a of the binding medium 5 on the mounting table 8 while pressing the binding portion region 5 c with each one end portion of the pair of pressing plates 15. By gradually lowering the presser 51 in this way, the set of pressing plates 15 is gradually deployed, so that the binding portion continuously toward the end portion in the direction away from the binding portion region 5c, that is, the spread direction. It is pressed to an area other than the area 5c. At this time, the presser 51 is lowered at a predetermined speed such that a portion in the vicinity of the binding area 5c moves smoothly along the spread surface 5a toward both ends in the spread direction. Thereby, the set of pressing plates 15 is continuously pressed along the spread surface 5a.

Finally, the presser 51 is lowered with respect to the spread surface 5a until the set of pressing plates 15 is developed in a flat shape, and the set of pressing plates 15 is placed on the spread surface 5a. Thus, the entire spread surface 5 a is pressed by the set of pressing plates 15 with the weight of the presser 51.

The presser 51 according to the fifth embodiment includes a guide frame 52 that supports the pair of pressing plates 15 so that the pair of pressing plates 15 can be bent, thereby improving operability when the pair of pressing plates 15 is deformed into a V shape and a flat shape. Can be increased. Therefore, according to the fifth embodiment, the user simply moves the guide frame 52 up and down, and the pair of pressing plates 15 allows the spread surface 5a of the binding medium 5 to be extended from the binding portion region 5c to both ends in the spread direction. Can be more easily pressed.

Also in the fifth embodiment, similarly to the first embodiment, the presser 51 starts pressing from the binding portion region 5c of the spread surface 5a, and after pressing the binding portion region 5c, the end portion in the spread direction of the spread surface 5a. Can be continuously pressed. Thereby, it is possible to suppress the occurrence of an overlapping portion in the binding portion region 5c of the spread surface 5a when the spread surface 5a is pressed by the presser 51, and the entire spread surface 5a can be read appropriately.

The binding medium pressing devices of Examples 1 to 5 are used in combination with a separate reading device, but may be incorporated in a binding medium reading device having a reading unit. The following Examples 6 to 9 (excluding the lifting mechanisms of Examples 7 and 8) differ from Examples 1 to 5 in which the binding medium 5 is automatically pressed by the pressing mechanism in that the binding medium 5 is manually pressed. . In Embodiments 1 to 5, after pressing from the binding portion area 5c of the spread surface 5a, a presser that can be bent to continuously press from the binding portion region 5c to the end portion in the spread direction along the spread surface 5a. 11 (21, 31, 41, 51) was used. On the other hand, in the following sixth to ninth embodiments, a flat presser is used, and the orientation of the spread surface 5a of the binding medium 5 placed on the placement table and the posture of the presser are controlled by the control unit 63 described later. Thus, it is possible to start pressing from the binding portion region 5c of the spread surface 5a in the same manner as when the bendable presser 11 (21, 31, 41, 51) is used.

The height detection unit 64 includes a line laser 64a that linearly irradiates laser light along the spread direction of the spread surface 5a, and a camera 64b that images the laser light irradiated on the spread surface 5a. The height detection unit 64 is controlled by the control unit 63.

The height detection unit 64 detects the height of the spread surface 5a, for example, the height of the binding portion region 5c of the spread surface 5a, based on an image obtained by imaging the spread surface 5a irradiated with the laser beam in a straight line. Specifically, the height detection unit 64 detects the height of each binding portion region 5c on both sides of the spread surface 5a. In other words, the height detection unit 64 detects the maximum height of each peak located on both sides of the valley of the binding portion region 5c on the spread surface 5a.

In addition, although the height detection part 64 in Example 6 detected the height of the binding part area | region 5c of the facing surface 5a, you may set so that the height of the whole facing surface 5a may be detected, and the facing surface 5a Can be detected with high accuracy. In the sixth embodiment, the height detection unit 64 detects the deflection in the height direction of the spread surface 5a using the line laser sensor, but other detection units detect the deflection of the entire spread surface 5a by three-dimensional measurement. May be used.

As shown in FIG. 11, the control unit 63 includes an illumination control unit 63a that controls the illumination unit 62b, an image reading control unit 63b that controls the image sensor 62a, and a height detection control unit that controls the height detection unit 64. 63c.

Further, the control unit 63 includes a motor control unit 63 h that controls a pressing mechanism 67 described later included in the binding medium pressing device 61.

FIG. 13A is a schematic cross-sectional view showing a binding medium pressing device 61 according to the sixth embodiment. 13B and 13C are schematic cross-sectional views for explaining an operation of pressing the spread surface 5a of the binding medium 5 placed on the placement table in the binding medium pressing device 61 according to the sixth embodiment.

As illustrated in FIG. 13A, the binding medium pressing device 61 according to the sixth embodiment is mounted on the mounting table 65 and a set of mounting tables 65 on which the binding medium 5 is mounted with the spread surface 5 a facing upward. And a flat presser 66 that presses the spread surface 5a of the binding medium 5 to the mounting table 65 side. Further, the binding medium pressing device 61 starts pressing from the binding portion area 5c of the binding medium 5 on the spread surface 5a by the presser 66, presses the binding section area 5c, and then moves away from the binding section area 5c. A pressing mechanism 67 for continuously pressing the area other than the binding area 5c is provided.

The mounting table 65 has a set of mounting plates 68 on which both sides on the back side of the spread surface 5 a of the binding medium 5 are mounted, and the set of mounting plates 68 are placed on the mounting table 65. The binding portions 5b of the binding medium 5 placed thereon are arranged with a predetermined interval at which insertion is possible.

The pressing mechanism 67 individually sets the mounting table 65 based on the support mechanism 72 that supports the set of mounting plates 68 so as to be movable in the height direction and the detection result of the height detection unit 64. And an elevating mechanism 73 as a drive mechanism for moving in the height direction.

The support mechanism 72 includes first and second

elastic members

74a and 74b that support a set of mounting plates 68, and a support base 75 on which the first and second

elastic members

74a and 74b are arranged. . The set of mounting plates 68 is supported by the first and second

elastic members

74a and 74b so as to be independently displaceable in the height direction. For this reason, the set of mounting plates 68 is displaced according to both sides of the spread surface 5a of the binding medium 5 mounted on the mounting table 65, so that the difference in page thickness between both sides of the spread surface 5a. Can be absorbed and can be supported so that both sides of the spread surface 5a have the same height.

In addition, when the binding medium 5 is placed on the pair of placement plates 68 in the sixth embodiment, the height of the spread surface 5a on the binding portion region 5c side is the end portion in the spread direction. The binding medium 5 is arranged so as to be supported in an inverted V shape in a posture higher than the height. In short, in the sixth embodiment, the binding portion region 5c of the spread surface 5a of the binding medium 5 placed on the mounting table 65 is set to a posture that is relatively higher than that of the spread surface 5a other than the binding portion region 5c. As a result, even when the flat presser 66 is used, the same pressing operation as in the case of using the presser 11 (21, 31, 41, 51) that can be bent in a V shape in the first to fifth embodiments is performed. It becomes possible.

For this reason, as shown in FIG. 13A, the set of mounting plates 68 is supported on a support base 75 via first and second

elastic members

74a and 74b having different lengths. The first elastic member 74a is longer than the second elastic member 74b. The 1st elastic member 74a is arrange | positioned at the binding part 5b side of the binding medium 5 mounted in the mounting base 65, and is connected with the mounting board 68 so that rotation is possible via the connection shaft, for example. The second elastic member 74b is disposed on the end side in the spread direction of the spread surface 5a of the binding medium 5 mounted on the mounting table 65, and can rotate with the mounting plate 68 via, for example, a connecting shaft. It is connected to. As the first and second

elastic members

74a and 74b, for example, coil springs or the like are used. Thereby, the set of mounting plates 68 can support both sides of the binding medium 5 in an inverted V-shaped posture in which the binding area 5c is higher than both ends in the spread direction of the spread surface 5a. It is possible. Further, the flat presser 66 in the sixth embodiment is fixed at a position facing the mounting table 65 in a state where the pressing surface facing the mounting table 65 is parallel to the horizontal direction.

Further, a pressure-sensitive sensor 74 as a pressing force detecting element for detecting a pressing force by which the spread surface 5 a of the binding medium 5 is pressed by the presser 66 is provided on the mounting surface of the set of mounting plates 68. Yes. For example, the pressure sensor 74 is arranged at the center or a plurality of positions on the placement surface. The control unit 63 can appropriately press both sides of the spread surface 5a by the presser 66 by controlling the pressing force on both sides of the spread surface 5a pressed by the presser 66 based on the output of the pressure sensor 74. .

The elevating mechanism 73 includes a rack 73a fixed to a support base 75 that supports the mounting plate 68, a pinion 73b that moves the rack 73a in the height direction, and a drive motor 73c that drives the pinion 73b. The rack 73a, pinion 73b, and drive motor 73c are supported on a base member 77. The raising / lowering mechanism 73 is driven and controlled by the control unit 63 based on the result detected by the height detection unit 64, thereby raising and lowering each placement plate 68 independently.

(Pressing operation in Example 6)
In the binding medium pressing device 61 configured as described above, the binding medium 5 placed on the placing table 65 has both ends of the spread area 5c of the spread surface 5a in the spread direction as shown in FIG. 13A. It becomes a higher posture. The binding medium pressing device 61 raises one of the set of placement plates 68 by the lifting mechanism 73 of the pressing mechanism 67 based on the detection result of the height detection unit 64. As a result, the binding medium 5 placed on the set of placement plates 68 is in a posture in which the heights of both sides of the spread surface 5a are adjusted.

After adjusting the heights of both sides of the spread surface 5 a of the binding medium 5 placed on the placement table 65 in this way, the binding medium pressing device 61 uses the lifting mechanism 73 to move the set of placement plates 68 to the presser. Raise toward 66. As a result, as shown in FIG. 13B, in the binding medium 5 placed on the placement table 65, the binding portion region 5 c of the spread surface 5 a is first pressed against the presser 66. Subsequently, the binding medium pressing device 61 further raises the pair of placement plates 68 toward the presser 66 by the lifting mechanism 73, so that the presser 66 is continuously extended from the binding portion region 5c to both ends in the spread direction. As shown in FIG. 13C, the entire spread surface 5a is pressed by the presser 66.

(Read operation in Example 6)
FIG. 14 is a flowchart for explaining an operation of reading the spread surface 5a of the binding medium 5 placed on the placement table 65 in the binding medium reading device 60 according to the sixth embodiment.

As illustrated in FIG. 14, the binding medium reading device 60 uses the height detection unit 64 to set the heights of both sides of the spread surface 5 a of the binding medium 5 placed on the placement table 65, for example, each binding on both sides. The maximum height of each partial area 5c is detected (step S1). Based on the maximum height of each binding portion region 5c on both sides detected by the height detection unit 64, the control unit 63 calculates the height difference between the highest points on both sides (left and right pages) of the spread surface 5a. Calculate (step S2).

Subsequently, the control unit 63 controls the pressing mechanism 67 of the binding medium pressing device 61 to support the mounting plate 68 that supports the page with the lower binding portion region 5c among the left and right pages of the spread surface 5a. Is raised by the above-described difference in height, the heights of the highest points of the left and right pages of the spread surface 5a are made equal (step S3). After matching the heights of the left and right pages of the spread surface 5a, the control unit 63 raises the mounting table 65 toward the presser 66, and the presser 66 uses the binding portion region 5c of the spread surface 5a in the spread direction. Press continuously to both ends.

After pressing both sides of the spread surface 5a on the presser 66, the binding medium reading device 60 is based on the output of each pressure sensor 74 of each placement plate 68 on which the left and right pages of the spread surface 5a are respectively placed. Then, it is determined whether the left and right pages of the spread surface 5a of the binding medium 5 are properly pressed against the presser 66 by the respective placement plates 68 (step S4). The control unit 63 determines whether or not each pressing force on the left and right pages of the spread surface 5a is appropriate depending on whether or not the output value of each pressure-sensitive sensor 74 is equal to or greater than a predetermined threshold value (step S5). In step S5, when the control unit 63 determines that the pressing force of the left and right pages of the spread surface 5a is appropriate (Yes), the reading unit 62 performs a reading operation of the spread surface 5a (step S6).

On the other hand, in step S5, when the pressing force of at least one of the left and right pages of the spread surface 5a is not appropriate (No), the control unit 63 determines whether or not a predetermined time has elapsed since the start of the reading operation. (Step S7). In step S7, when the control unit 63 determines that the predetermined time has not elapsed since the start of the reading operation (No), for example, the control unit 63 uses the pressing mechanism on the mounting plate 68 on which the page with the smaller pressing force is mounted. By raising it by 67, the pressing force of the page is increased (step S9). At this time, if the pressing force of the left and right pages is not appropriate in step S5, the control unit 63 raises the set of mounting plates 68 by the pressing mechanism 67, thereby reducing the pressing force of the left and right pages. Enlarge. In step S 9, the control unit 63 raises the placement plate 68 and then returns to step S 5 to determine again whether or not the pressing force of the left and right pages is appropriate.

Again, in step S7, the control unit 63 determines whether or not a predetermined time has elapsed since the start of the reading operation. As described above, as a result of repeating the operation of raising the placement plate 68 in order to optimize the pressing force of the left and right pages, a predetermined time may elapse from the start of the reading operation. In step S7, when it is determined that the predetermined time has elapsed since the start of the reading operation (Yes), the control unit 63 determines that the spread surface 5a is unreadable (timeout) (step S8). Then, the reading operation of the binding medium 5 is finished.

As described above, the sixth embodiment has the pressing mechanism 67 so that even when the flat presser 66 is used, the spread surface 5a is started to be pressed from the binding portion region 5c, and the binding portion region 5c is pressed. Then, areas other than the binding area 5c can be continuously pressed in a direction away from the binding area 5c. Accordingly, also in the sixth embodiment, it is possible to appropriately read the entire spread surface 5a including the binding portion region 5c of the spread surface 5a of the binding medium 5, and avoid damage to the binding portion region 5c of the spread surface 5a. be able to.

For this reason, the holding member 83 is provided so as to be displaceable in the height direction while holding the binding portion 5b in a posture rotated by the rotation mechanism 86 when the binding medium 5 is pressed by the presser 66. Yes.

Further, the elastic member 88 that supports the holding member 83 is longer than the elastic member 88 that supports the mounting plate 68, and the height of the holding member 83 is higher than the height of each mounting plate 68. . Thereby, the binding medium 5 in which the binding portion 5b is held by the holding member 83 is in a posture in which the binding portion region 5c of the spread surface 5a is relatively high on the spread surface 5a. For example, a coil spring is used as the elastic member 88, but a link mechanism or the like that supports the mounting plate 68 and the holding member 83 so as to be elastically displaceable may be used.

The rotation mechanism 86 includes a rotation shaft 86a provided on the holding member 83 along the extending direction of the binding portion 5b, and a drive motor 86b that rotates the rotation shaft 86a via a gear group (not shown).

In the seventh embodiment, the lifting mechanism 87 is configured to be lifted and lowered manually by the user rotating the handle 87a. However, the lifting and lowering operation may be controlled by the control unit 63. Further, the elevating mechanism 87 may be configured to elevate the base member 77 by a rack and a pinion like the elevating mechanism 73 of the sixth embodiment.

(Pressing operation in Example 7)
In the binding medium pressing device 71 configured as described above, the binding medium 5 placed on the placement table 65 is formed on both sides of the spread surface 5a on a set of placement plates 68 as shown in FIG. 15A. The back side is placed and the binding portion 5 b is held by the holding member 83. Based on the detection result of the height detector 64, the binding medium pressing device 71 rotates the holding member 83 around the rotation axis 86a by a predetermined rotation angle by the rotation mechanism 86 of the pressing mechanism 84, as shown in FIG. 15B. Move. At this time, in the support mechanism 85, the binding medium 5 whose posture is changed with the rotation of the holding member 83 by elastically displacing the mounting members 68 and the elastic members 88 that support the holding members 83. Is supported stably. As a result, the binding medium 5 placed on the pair of placement plates 68 and the holding member 83 has a posture in which the heights of both sides of the spread surface 5a are adjusted.

After adjusting the heights of both sides of the spread surface 5 a of the binding medium 5 placed on the placement table 65 in this way, the binding medium pressing device 71 is set as a set by the lifting mechanism 87 of the pressing mechanism 84. The plate 68 and the holding member 83 are raised toward the presser 66. As a result, as shown in FIG. 15C, the binding medium 5 placed on the placement table 65 is first pressed against the presser 66 at the binding portion region 5 c of the spread surface 5 a. Subsequently, the binding medium pressing device 71 continuously raises the pair of mounting plates 68 and the holding member 83 toward the presser 66 by the elevating mechanism 87, so that the binding medium pressing device 71 continues from the binding portion region 5c to both ends in the spread direction. As shown in FIG. 15D, the entire area of the spread surface 5 a is pressed by the presser 66.

(Read operation in Example 7)
FIG. 16 is a flowchart for explaining an operation of reading the spread surface 5a of the binding medium 5 placed on the placing table 65 in the binding medium reading device according to the seventh embodiment.

As illustrated in FIG. 16, the binding medium reading device according to the seventh embodiment uses the height detection unit 64 to measure the heights of both sides of the spread surface 5 a of the binding medium 5 placed on the placing table 65, for example, both sides. The maximum height of each binding area 5c is detected (step S11). Based on the maximum height of each binding portion region 5c on both sides detected by the height detection unit 64, the control unit 63 calculates the height difference between the highest points on both sides (left and right pages) of the spread surface 5a. Calculation is performed (step S12).

Subsequently, the control unit 63 controls the pressing mechanism 84 of the binding medium pressing device 71 to rotate the holding member 83 by a predetermined rotation angle based on the height difference between the left and right pages of the spread surface 5a, thereby opening the spread. The heights of the highest points of the left and right pages of the surface 5a are made equal (step S13). After matching the heights of the left and right pages of the spread surface 5a, the control unit 63 raises the mounting table 65 toward the presser 66, and the presser 66 uses the binding portion region 5c of the spread surface 5a in the spread direction. Press continuously to both ends.

After causing the presser 66 to press both sides of the spread surface 5a, the binding medium reading device is based on the output of each pressure sensor 74 of each placement plate 68 on which the left and right pages of the spread surface 5a are placed. It is determined whether the left and right pages of the spread surface 5a of the binding medium 5 are properly pressed against the presser 66 by the respective placement plates 68 (step S14). The control unit 63 determines whether or not each pressing force on the left and right pages of the spread surface 5a is appropriate depending on whether or not the output value of each pressure sensor 74 is equal to or greater than a predetermined threshold (step S15). In step S15, when the control unit 63 determines that the pressing force of the left and right pages of the spread surface 5a is appropriate (Yes), the reading unit 62 performs a reading operation of the spread surface 5a (step S16).

On the other hand, in step S15, when the pressing force of at least one of the left and right pages of the spread surface 5a is not appropriate (No), the control unit 63 determines whether or not a predetermined time has elapsed since the start of the reading operation. (Step S17). In step S 17, when the control unit 63 determines that the predetermined time has not elapsed since the start of the reading operation (No), for example, when the pressing force of the left and right pages is small, the pressing mechanism 84 sets a set of mounting plates. By raising 68, the pressing force of the left and right pages is increased (step S19). In step S 19, the control unit 63 raises the placement plate 68 and then returns to step S 15 to determine again whether or not the pressing force of the left and right pages is appropriate.

Again, in step S17, the control unit 63 determines whether or not a predetermined time has elapsed since the start of the reading operation. As described above, as a result of repeating the operation of raising the placement plate 68 in order to optimize the pressing force of the left and right pages, a predetermined time may elapse from the start of the reading operation. In step S17, when it is determined that the predetermined time has elapsed since the start of the reading operation (Yes), the control unit 63 determines that the spread surface 5a is unreadable (timeout) (step S18). Then, the reading operation of the binding medium 5 is finished.

As described above, the seventh embodiment has the pressing mechanism 84, so that even when the flat presser 66 is used, the spread surface 5a is started to be pressed from the binding portion region 5c, and the binding portion region 5c is pressed. Then, areas other than the binding area 5c can be continuously pressed in a direction away from the binding area 5c. Therefore, also in Example 7, it becomes possible to properly read the entire spread surface 5a including the binding portion region 5c of the spread surface 5a of the binding medium 5, and avoid damage to the binding portion region 5c of the spread surface 5a. be able to.

FIG. 17A is a schematic cross-sectional view illustrating the binding medium pressing device according to the eighth embodiment. FIGS. 17B, 17C, and 17D are schematic cross-sectional views for explaining an operation of pressing the spread surface 5a of the binding medium 5 placed on the placement table 65 in the binding medium pressing device of the eighth embodiment. is there. The eighth embodiment is different from the seventh embodiment in which the presser 66 is rotated with respect to the spread surface 5a when the spreader 5 is pressed by the presser 66, and the binding portion 5b of the binding medium 5 is rotated.

As illustrated in FIG. 17A, the binding medium pressing device 81 according to the eighth embodiment holds a mounting table 65 on which the binding medium 5 is placed with the spread surface 5a facing upward, and a binding portion 5b of the binding medium 5. And a flat presser 66 that presses the spread surface 5a of the binding medium 5 mounted on the mounting table 65 toward the mounting table 65. The binding medium pressing device 81 starts pressing from the binding portion area 5c of the binding medium 5 on the spread surface 5a by the presser 66, presses the binding section area 5c, and then moves away from the binding section area 5c. A pressing mechanism 92 for continuously pressing the area other than the binding area 5c is provided.

The pressing mechanism 92 includes a support mechanism 85 that supports the pair of mounting plates 68 and the holding member 83 so as to be movable in the height direction, and a result of detection by the height detection unit 64. A rotation mechanism 93 as a drive mechanism that rotates about an axis parallel to the extending direction of 5b, and an elevating mechanism 87 that elevates and lowers the pair of mounting plates 68 and the holding member 83 in the height direction.

Since the support mechanism 85 and the lifting mechanism 87 have the same configuration as that of the seventh embodiment, description thereof is omitted. The rotation mechanism 93 includes a rotation shaft 93a that rotatably supports the presser 66, and a drive motor 93b that rotates the rotation shaft 93a via a gear group (not shown). The rotation mechanism 93 and the presser 66 are supported by the base member 77 via a frame (not shown), and the drive motor 93 b is disposed on the base member 77.

(Pressing operation in Example 8)
In the binding medium pressing device 81 configured as described above, the binding medium 5 placed on the placement table 65 is placed on the back side of both sides of the spread surface 5a on a set of placement plates 68 as shown in FIG. 17A. Is mounted, and the binding portion 5 b is held by the holding member 83. As shown in FIG. 17B, the binding medium pressing device 81 rotates the presser 66 about the rotation axis 93a by a predetermined rotation angle by the rotation mechanism 93 of the pressing mechanism 92 based on the detection result of the height detection unit 64. Let As a result, the posture of the pressing surface of the presser 66 with respect to both sides of the spread surface 5a of the binding medium 5 placed on the pair of placement plates 68 and the holding member 83 is adjusted.

After adjusting the posture of the presser 66 in this way, the binding medium pressing device 81 raises the pair of mounting plates 68 and the holding member 83 toward the presser 66 by the lifting mechanism 87 of the pressing mechanism 92. As a result, as shown in FIG. 17C, the binding medium 5 placed on the placement table 65 is first pressed against the presser 66 in the binding portion region 5 c of the spread surface 5 a. Subsequently, the binding medium pressing device 81 rotates the presser 66 by the rotating mechanism 93 so that the pressing surface of the presser 66 becomes horizontal, and the pair of the mounting plate 68 and the holding member 83 by the lifting mechanism 87. Raise further toward the presser 66. As a result, the binding medium pressing device 81 continuously presses the presser 66 from the binding portion region 5c of the spread surface 5a to both ends in the spread direction, and as shown in FIG. Press.

(Read operation in Example 8)
FIG. 18 is a flowchart for explaining the operation of reading the spread surface 5a of the binding medium 5 placed on the placement table 65 in the binding medium pressing device according to the eighth embodiment.

As illustrated in FIG. 18, the binding medium reading device according to the eighth embodiment uses the height detection unit 64 to measure the heights of both sides of the spread surface 5 a of the binding medium 5 placed on the placing table 65, for example, both sides. The maximum height of each binding area 5c is detected (step S21). The control unit 63 presses the presser 66 with a straight line connecting the highest points of both sides (left and right pages) of the spread surface 5a based on the maximum height of each binding portion region 5c on both sides detected by the height detection unit 64. The angle between the surface and the distance from the presser 66 to the spread surface 5a of the binding medium 5 is calculated (step S22). Here, the distance from the presser 66 to the spread surface 5a of the binding medium 5 refers to the distance in the height direction between the straight line and the pressing surface of the presser 66.

Subsequently, the control unit 63 controls the pressing mechanism 92 of the binding medium pressing device 81, and rotates the presser 66 by an angle formed by the above-described straight line and the pressing surface of the presser 66, whereby the above-described straight line and the presser are rotated. 66 is parallel to the pressing surface. Then, the control unit 63 lowers the presser 66 by the above-mentioned distance while the angle formed by the above-described straight line and the pressing surface of the presser 66 on the left and right pages of the spread surface 5a is zero, that is, in a parallel state. It is made to contact the binding part area | region 5c of the facing surface 5a (step S23). Next, the control unit 63 rotates the presser 66 to level the pressing surface of the presser 66 and raises the spread surface 5a toward the presser 66, thereby pressing the spread surface 5a by the presser 66 ( Step S24). Accordingly, the pressing mechanism 92 continuously presses from the binding portion region 5c of the spread surface 5a to both ends in the spread direction by the presser 66, and presses the entire spread surface 5a.

After causing the presser 66 to press both sides of the spread surface 5a, the binding medium reading device is based on the output of each pressure sensor 74 of each placement plate 68 on which the left and right pages of the spread surface 5a are placed. It is determined whether the left and right pages of the spread surface 5a of the binding medium 5 are properly pressed against the presser 66 by the placement plates 68 (step S25). The control unit 63 determines whether or not each pressing force on the left and right pages of the spread surface 5a is appropriate depending on whether or not the output value of each pressure-sensitive sensor 74 is greater than or equal to a predetermined threshold (step S26). In step 26S, when the control unit 63 determines that the pressing force of the left and right pages of the spread surface 5a is appropriate (Yes), the reading unit 62 performs the reading operation of the spread surface 5a (step S27).

On the other hand, in step S26, when the pressing force of at least one of the left and right pages of the spread surface 5a is not appropriate (No), the control unit 63 determines whether a predetermined time has elapsed since the start of the reading operation. (Step S28). In step S28, when the control unit 63 determines that the predetermined time has not elapsed since the start of the reading operation (No), for example, when the pressing force of the left and right pages is small, the pressing mechanism 92 sets a set of mounting plates. By raising 68, the pressing force of the left and right pages is increased (step S30). In step S 30, the control unit 63 raises the placement plate 68 and then returns to step S 26 to determine again whether or not the pressing force of the left and right pages is appropriate.

Again, in step S28, the control unit 63 determines whether or not a predetermined time has elapsed since the start of the reading operation. As described above, as a result of repeating the operation of raising the placement plate 68 in order to optimize the pressing force of the left and right pages, a predetermined time may elapse from the start of the reading operation. In step S28, when it is determined that the predetermined time has elapsed since the start of the reading operation (Yes), the control unit 63 determines that the spread surface 5a is unreadable (timeout) (step S29). Then, the reading operation of the binding medium 5 is finished.

As described above, the eighth embodiment has the pressing mechanism 92 so that even when the flat presser 66 is used, the spread surface 5a is started to be pressed from the binding portion region 5c and the binding portion region 5c is pressed. Then, areas other than the binding area 5c can be continuously pressed in a direction away from the binding area 5c. Accordingly, also in the eighth embodiment, it is possible to appropriately read the entire spread surface 5a including the binding portion region 5c of the spread surface 5a of the binding medium 5, and avoid damage to the binding portion region 5c of the spread surface 5a. be able to.

FIG. 19A is a schematic cross-sectional view illustrating the binding medium pressing device according to the ninth embodiment. 19B, 19C, and 19D are schematic cross-sectional views for explaining an operation of pressing the spread surface 5a of the binding medium 5 placed on the placement table 65 in the binding medium pressing device of the ninth embodiment. is there. The ninth embodiment is different from the sixth embodiment in which the presser 66 is lowered with respect to the spread surface 5a when the spreader 66 presses the spread surface 5a.

As illustrated in FIG. 19A, the binding medium pressing device 91 according to the ninth embodiment holds a mounting table 65 on which the binding medium 5 is placed with the spread surface 5 a facing upward, and a binding portion 5 b of the binding medium 5. And a flat presser 66 that presses the spread surface 5a of the binding medium 5 mounted on the mounting table 65 toward the mounting table 65. Further, the binding medium pressing device 91 starts pressing from the binding portion area 5c of the binding medium 5 in the spread surface 5a by the presser 66, presses the binding section area 5c, and then moves away from the binding section area 5c. A pressing mechanism 96 for continuously pressing the region other than the binding portion region 5c is provided.

The pressing mechanism 96 is a set of a rotation mechanism 86 as a drive mechanism that rotates the holding member 83 around an axis parallel to the extending direction of the binding portion 5b based on the result detected by the height detection unit 64. And a support mechanism 85 that supports the mounting plate 68 and the holding member 83 so as to be movable in the height direction, and an elevating mechanism 97 that raises and lowers the presser 66 in the height direction.

The rotation mechanism 86 and the support mechanism 85 have the same configuration as that of the seventh embodiment, and thus description thereof is omitted. The elevating mechanism 97 includes a rack 97a fixed to the presser 66, a pinion 97b that moves the rack 97a in the height direction, and a drive motor 97c that drives the pinion 97b. The elevating mechanism 97 and the presser 66 are supported by the base member 77 through a frame (not shown).

(Pressing operation in Example 9)
In the binding medium pressing device 91 configured as described above, the binding medium 5 placed on the placement table 65 is formed on both sides of the spread surface 5a on a set of placement plates 68 as shown in FIG. 19A. The back side is placed and the binding portion 5 b is held by the holding member 83. As shown in FIG. 19B, the binding medium pressing device 91 rotates the holding member 83 around the rotation axis 86a by a predetermined rotation angle based on the detection result of the height detection unit 64, as shown in FIG. 19B. Move. At this time, in the support mechanism 85, the binding medium 5 whose posture is changed with the rotation of the holding member 83 by elastically displacing the mounting members 68 and the elastic members 88 that support the holding members 83. Is supported stably. As a result, the binding medium 5 placed on the pair of placement plates 68 and the holding member 83 has a posture in which the heights of both sides of the spread surface 5a are adjusted.

After adjusting the heights of both sides of the spread surface 5 a of the binding medium 5 placed on the placement table 65 in this way, the binding medium pressing device 91 controls the presser 66 with the lifting mechanism 97 of the pressing mechanism 96. The binding medium 5 placed on the set placing plate 68 and the holding member 83 is lowered toward the spread surface 5a. As a result, as shown in FIG. 19C, the binding medium 5 placed on the placement table 65 is first pressed against the presser 66 at the binding portion region 5 c of the spread surface 5 a. Subsequently, the binding medium pressing device 91 further presses the presser 66 from the binding region 5c to both ends in the spread direction by further lowering the presser 66 with respect to the spread surface 5a by the lifting mechanism 97. As shown in FIG. 19D, the entire spread surface 5 a is pressed by the presser 66.

(Read operation in Example 9)
FIG. 20 is a flowchart for explaining an operation of reading the spread surface 5a of the binding medium 5 placed on the placement table 65 in the binding medium reading device according to the ninth embodiment.

As illustrated in FIG. 20, the binding medium reading device according to the ninth embodiment uses the height detection unit 64 to measure the height of both sides of the spread surface 5 a of the binding medium 5 placed on the mounting table 65, for example, both sides. The maximum height of each binding area 5c is detected (step S31). Based on the maximum height of each binding portion region 5c on both sides detected by the height detection unit 64, the control unit 63 calculates the height difference between the highest points on both sides (left and right pages) of the spread surface 5a. Calculation is performed (step S32).

Subsequently, the control unit 63 controls the pressing mechanism 96 of the binding medium pressing device 91 to rotate the holding member 83 by a predetermined rotation angle based on the height difference between the left and right pages of the spread surface 5a, thereby opening the spread. The heights of the highest points of the left and right pages of the surface 5a are made equal (step S33). After matching the heights of the left and right pages of the spread surface 5a, the control unit 63 lowers the presser 66 toward the spread surface 5a and causes the presser 66 to move from the binding area 5c of the spread surface 5a in the spread direction. Press continuously to both ends.

After causing the presser 66 to press both sides of the spread surface 5a, the binding medium reading device is based on the output of each pressure sensor 74 of each placement plate 68 on which the left and right pages of the spread surface 5a are placed. It is determined whether the left and right pages of the spread surface 5a of the binding medium 5 are properly pressed against the presser 66 by the respective placement plates 68 (step S34). The control unit 63 determines whether or not each pressing force on the left and right pages of the spread surface 5a is appropriate depending on whether or not the output value of each pressure sensor 74 is greater than or equal to a predetermined threshold (step S35). In step S35, when the control unit 63 determines that the pressing force of the left and right pages of the spread surface 5a is appropriate (Yes), the reading unit 62 performs a reading operation of the spread surface 5a (step S36).

On the other hand, in step S35, when the pressing force of at least one of the left and right pages of the spread surface 5a is not appropriate (No), the control unit 63 determines whether or not a predetermined time has elapsed since the start of the reading operation. (Step S37). In step S37, when it is determined that the predetermined time has not elapsed since the start of the reading operation (No), the control unit 63 lowers the presser 66 by the pressing mechanism 96 when, for example, the pressing force of the left and right pages is small. Thus, the pressing force on the left and right pages is increased (step S39). In step S39, the control unit 63 lowers the presser 66 and then returns to step S35 to determine again whether or not the pressing force of the left and right pages is appropriate.

Again, in step S37, the control unit 63 determines whether or not a predetermined time has elapsed since the start of the reading operation. As described above, as a result of repeating the operation of raising the placement plate 68 in order to optimize the pressing force of the left and right pages, a predetermined time may elapse from the start of the reading operation. In step S37, when it is determined that the predetermined time has elapsed since the start of the reading operation (Yes), the control unit 63 determines that the spread surface 5a is unreadable (timeout) (step S38). Then, the reading operation of the binding medium 5 is finished.

As described above, the ninth embodiment has the pressing mechanism 96 so that even when the flat presser 66 is used, the spread surface 5a is started to be pressed from the binding portion region 5c and the binding portion region 5c is pressed. Then, areas other than the binding area 5c can be continuously pressed in a direction away from the binding area 5c. Therefore, also in Example 9, it becomes possible to properly read the entire spread surface 5a including the binding portion region 5c of the spread surface 5a of the binding medium 5, and avoid damage to the binding portion region 5c of the spread surface 5a. be able to.

In the above-described Examples 6 to 9, the flat presser is used. However, if necessary, it may be used in combination with the presser of Examples 1 to 5 described above, and the bending portion 5c bends. It is possible to improve the accuracy of correcting.
