It is a perspective view which shows the external appearance structure (back surface) of the imaging device stand by this embodiment. It is a perspective view which shows the external appearance structure (illumination part) of the imaging device stand by this embodiment. It is a perspective view which shows the state which installed the tablet terminal in the imaging device stand by this embodiment. FIG. 4 is a top view showing an appearance of a band for fixing the tablet terminal to the imaging device stand according to the present embodiment, and a partial perspective view showing a state where the tablet terminal is fixed to the imaging device stand by the band. In the imaging device stand by this embodiment, it is a top view which shows the relationship between the fixed position of a tablet terminal, and the size of a book. It is a perspective view which shows the accommodation method of the imaging device stand 40 by this embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing an appearance of a page turning apparatus 1 using an imaging apparatus stand 40 according to an embodiment of the present invention. In the following description, a case where the page P of the book B is turned from left to right will be described. In FIG. 1, the page turning apparatus 1 includes a page turning main body 10 for turning a page P of a book B, and a holding table 30 for holding the opened book B.

  The page turning main body 10 includes a substantially rectangular parallelepiped storage case 11, an arm 12 that can be stored in the storage case 11, and a suction unit that is attached to the tip of the arm 12 and sucks the page P of book B 13, a drive unit 14 such as a motor that reciprocally swings the arm unit 12 from right to left and from left to right, and a page P that is at the turning destination position. Is provided with a blower 15 for separating the page from the suction part (adhesive roller part) 13 by applying wind.

  The holding table 30 includes a pair of holding plates 31 and 32 that can be folded by hinges. Here, when the page P of the book B is turned from left to right, one holding plate 31 arranged on the left side of the pair of holding plates 31 and 32 is placed along the table and on the right side. The other holding plate 32 to be placed is inclined and placed on the table so that it rises at a predetermined angle with respect to the one holding plate 31. On one holding plate 31, the page P that is the turning origin position of the book B is placed, and on the other holding plate 32, the page P that is the turning destination position of the book B is placed.

  As a result, the holding table 30 holds the book B so that the page P at the turning destination is inclined in the direction that occurs with respect to the binding of the book B rather than the page P at the turning original position. Since the pair of holding plates 31 and 32 are foldable by hinges, the angle formed by the pair of holding plates 31 and 32 can be adjusted, and the inclination angle θ with respect to the horizontal plane of the page P at the turning point position. Is adjustable. The inclination angle θ is preferably adjusted within a range of 30 to 45 degrees.

  The imaging device stand 40 is a stage 411 extending diagonally with respect to the page P at the original turning position of the opened book B of the imaging target (imaging target) and parallel to the installation surface of the imaging device stand 40. have. In the following description, it is assumed that a tablet terminal is installed as an imaging device on the stage 411. However, the present invention is not limited to the tablet terminal. Hereinafter, the imaging device stand 40 of the present invention will be described in detail, and the description of the page turning device 1 will be omitted.

  FIG. 2 is a perspective view showing an external configuration (front) of the imaging apparatus stand 40 according to the present embodiment. FIG. 2 shows a state when the imaging apparatus stand 40 is used (in a self-supporting state). The imaging apparatus stand 40 includes an L-shaped first member 41, an L-shaped second member 42, an adjustment unit 43 that moves the first member 41 up and down with respect to the second member 42, and a second member 42 and a third member 44 (a pedestal forming an installation surface of the imaging device stand 40) coupled in a freely rotating direction and a third member 44 rotatably coupled.

  The first member 41 includes a stage 411 extending in a right angle direction. An elliptical opening 412 is formed in the vicinity of the tip of the stage 411 along the longitudinal direction. On the stage 411, a sheet 413 made of a material (EPP; foamed polypropylene or the like) that serves both as slip prevention and shock absorption is provided so as to avoid the opening 412. A camera unit (lens opening) such as a tablet terminal (not shown) is placed on the stage 411 so as to face downward (details will be described later). In addition, in order to mount a tablet terminal, the 1st member 41 must be at least planar shape (plate shape). A portion extending in the vertical direction of the first member 41 is inserted into the adjustment portion 43.

  A portion extending in the vertical direction of the second member 42 is inserted into the adjustment portion 43 in the same manner as the first member 41. On the other hand, a portion of the lower part of the second member 42 that extends in the perpendicular direction is coupled to one end of the third member 44 so as to be rotatable about the rotation axis RA.

  The adjustment unit 43 includes an operation knob 50 to be described later, and the first member 41, that is, the stage 411 is moved (lifted / lowered) in the vertical direction by the operation of the operation knob 50.

  The third member 44 functions as a leg for making the imaging device stand 40 self-supporting.

  Further, as described above, the portion of the second member 42 extending in the direction perpendicular to the end of the third member 44 is coupled to be rotatable about the rotation axis RA. That is, the second member 42 (including the adjustment unit 43 and the first member 41) can be rotated in the arrow direction A with respect to the third member 44. The fact that the second member 42 is rotatable means that the first member 41 and the stage 411 are rotatable around the rotation axis RA, and the position of the stage 411 (position relative to the book B) can be varied. It is.

  The reference position is a position where the second member 42 (including the adjusting portion 43 and the first member 41) is rotated to a position where the mark M1 attached to the second member 42 and the mark M2 attached to the third member 44 are aligned. It becomes. That is, the stage 411 of the first member 41 extends in a diagonal direction so as to face the page P of the book B installed in the page turning apparatus 1 by setting the marks M1 and M2 at a position where the marks M1 and M2 are aligned. (Details will be described later). At this reference position, the camera part of the tablet terminal placed on the stage 411 normally takes a picture (photographs) of the page P of the book B installed in the page turning apparatus 1.

  An illumination device 45 using LEDs as light emitting elements is provided on the lower surface of the stage 411 of the first member 41.

  FIG. 3 is a perspective view showing an external configuration (rear surface) of the imaging apparatus stand 40 according to the present embodiment. FIG. 3 shows a state when the imaging apparatus stand 40 is used (in a self-supporting state). As described above, the adjustment unit 43 includes the operation knob 50 for moving the first member 41 up and down. When the operation knob 50 is rotated clockwise, the first member 41 rises. That is, the stage 411 is raised. On the other hand, when the operation knob 50 is rotated counterclockwise, the first member 41 is lowered. That is, the stage 411 is lowered.

  As the stage 411 is moved up and down, the angle of view of an imaging apparatus such as a tablet terminal placed on the stage 411 changes. When shooting a page of a relatively small book (eg, a paperback book; 105 mm × 148 mm, etc.), the stage is lowered to reduce the distance between the camera unit and the book to reduce the angle of view, and a relatively large book ( For example, when shooting a page of A4 size (210 mm × 297 mm), the stage 411 is raised to widen the distance between the camera unit and the book and widen the angle of view.

  The third member 44 is inserted into the opening 33 provided in the holding table 30 of the page turning apparatus 1. Thereby, the relative position with respect to the page turning apparatus 1 of the imaging device stand 40 is physically determined. In other words, the relative position of the tablet B with respect to the original page P of the book B is determined.

  FIG. 4 is a perspective view showing an external configuration (illumination unit) of the imaging apparatus stand 40 according to the present embodiment. The lighting device 45 described above is provided on the lower surface of the stage 411 of the first member 41. The illumination device 45 includes a lamp shade 452 having a shape having an opening 451 on the center side of an elliptical shape so as to surround the opening 412 provided in the stage 411. The lamp shade 452 diffuses light from an LED (not shown) and makes the illuminance of the irradiated light substantially uniform on the page P of book B. In addition, it also serves to protect the LED, which is a light emitting element.

  FIG. 5 is a perspective view illustrating a state where the tablet terminal 60 is installed on the imaging apparatus stand 40 according to the present embodiment. In the illustrated example, it is assumed that the page P of book B is captured by the camera unit 62 provided on the back surface of the tablet terminal 60 (the opposite side of the display panel 61). Therefore, the tablet terminal 60 is placed on the stage 411 so that the back surface is the lower side and the display panel 61 is the upper side so that the camera unit 62 (lens opening) of the tablet terminal 60 can accommodate the page P of the book B within the angle of view. Place on top.

  At this time, the camera part (lens opening part) 62 is positioned so as to be directed to the page P of the book B from the opening part 412 provided on the stage 411 and positioned substantially at the center of the book B to be photographed. . In positioning, if a shooting mode by a predetermined application is executed, a through image currently captured by the camera unit 62 is displayed on the display panel 61. Therefore, the page P is displayed within the angle of view while viewing the display. What is necessary is just to determine the position of the tablet terminal 60 so that it may be settled. When the position of the tablet terminal 60 is determined, the elastic band 70 made of silicon is bridged on the diagonal corner of the tablet terminal 60 and fixed to the stage 411. In order to fix the diagonal corners of the tablet terminal 60 with the band 70, at least the corners of the tablet terminal 60 must protrude from the stage 411. Since the sheet 413 provided on the stage 411 is interposed between the tablet terminal 60 and the stage 411, the tablet terminal 60 is not damaged. A fixing method using the band 70 will be described later.

  FIG. 6A is a top view showing an appearance of a band for fixing the tablet terminal 60 to the imaging device stand 40 according to the embodiment, and FIG. 6B is an imaging device for the tablet terminal 60 with the band 70. FIG. 4 is a partial perspective view showing a state fixed to a stand 40. The band 70 is made of a material such as silicon that has elasticity and does not damage the tablet terminal 60. The band 70 has a ladder shape having a plurality of openings 71 as shown in the figure.

  In order to fix the tablet terminal 60, the opening 71 at one end of the band 70 is hung on one corner on the diagonal of the tablet terminal 60 positioned on the stage 411, and the other end is passed under the stage 411 and the other. The opening 71 at the end is hung on the other corner on the diagonal of the tablet terminal 60. Although the tablet terminal 60 is not completely fixed, the band 70 and the sheet 413 are made of a material that is difficult to slip, so that the tablet terminal 60 does not move inadvertently during shooting, or shooting blur does not occur. Fully fixed.

  In order to securely fix so as not to loosen, the position of the opening 71 to be hung on the corner of the tablet terminal 60 may be changed in accordance with the extension of the band 70 and the size of the tablet terminal 60. That is, if the tablet terminal 60 is a small size, the opening 71 at either end and the central opening 71 may be hung on the tablet terminal 60. The part 71 may be hung on the tablet terminal 60.

  Thus, since it fixes from the back surface of the tablet terminal 60, since the display panel 61 is not covered, visibility is not impaired. Further, by forming the band 70 from a material such as silicon, sufficient stretchability and durability can be obtained, and the tablet terminal 60 can be fixed without being damaged.

  Note that the number and size of the openings 71 may be set as appropriate according to the strength and length of the band 70 and are not limited to the illustrated example.

  FIG. 7 is a top view showing the relationship between the fixed position of the tablet terminal 60 and the size of the book B in the imaging apparatus stand 40 according to the present embodiment. FIG. 7 shows the relationship among the page turning device 1, the imaging device stand 40, and the size of book B. As described above, the third member 44 of the imaging device stand 40 is inserted into the opening 33 provided in the holding table 30 of the page turning device 1. The opening 33 is a side of the pedestal of the holding table 30 (the lower right side of the holding table 30 in FIG. 1) on which the page turning main body 10 is arranged to support the holding plate 32 at the page turning destination at a predetermined angle. It is provided on the side surface (right back in FIG. 1). In addition, the concave portion of the holding base 30 into which the third member 44 is inserted through the opening 33 is drawn from the opening 33 to the lower part of the base of the holding base 30 (the lower right side of the holding base 30 in FIG. 1). It extends to the near side. As described above, since the third member 44 is detachably fixed to the holding base 30 of the page turning device 1, the relative position of the imaging device stand 40 with respect to the page turning device 1 is physically determined.

  Further, since one end of the third member 44 is bent, the housing of the storage case 11 is brought into contact with the end surface of the bent third member 44 when the storage case 11 is set at a predetermined position. Thus, the position of the storage case 11 is uniquely determined. That is, the storage case 11 is restricted from moving to the turning destination position of the page P of the book B that is opened. Further, the relative positions of the page turning main body 10 during the page turning operation, the holding base 30 for holding the opened book B, and the opened book B are physically determined. Thereby, the page turning apparatus 1 can be set easily.

  Then, the second member 42 (including the adjustment unit 43 and the first member 41) is rotated to a position where the marks M1 and M2 attached to the second member 42 and the third member 44 of the imaging device stand 40 are aligned. The stage 411 of the first member 41 is positioned substantially diagonally with respect to the holding plate 31. That is, since the opening 412 provided in the stage 411 is positioned in a substantially diagonal direction of the book B placed on the holding plate 31, the tablet terminal 60 placed on the stage 411 is appropriately moved. Thus, both the relatively small book B1 such as a paperback book (105 mm × 148 mm) and the relatively large book B2 such as an A4 plate 81 (210 mm × 297 mm), the image of the camera unit 62 of the tablet terminal 60 is displayed. Can fit in the corner.

  In addition, if the rotation angle of the first member 41 is appropriately adjusted regardless of the marks M1 and M2, the image of the camera unit 62 of the tablet terminal 60 can be obtained even if the book B has a different aspect ratio or aspect ratio different from that illustrated. It is possible to fit in the corner.

  FIG. 8 is a perspective view illustrating a method of storing the imaging device stand 40 according to the present embodiment. When the imaging device stand 40 is stored, the third member 44 is rotated around the rotation axis RA (see FIG. 3) to form a U-shape as a whole as shown in FIG. The angle is set so that the lower side of the member 44 is flush. Moreover, about the page turning apparatus 1, the holding plate 32 is folded by a hinge and closed. Then, both sides of the page turning apparatus 1 are stored so as to be sandwiched between the first member 41 and the third member 44 of the imaging apparatus stand 40. Thereby, it becomes possible to store in one storage bag etc. very compactly.

  In the above-described embodiment, the example in which the camera unit 62 (lens opening) is arranged in the back corner of the tablet terminal 60 has been described. However, the present invention is not limited thereto, and the camera unit 62 (lens opening) is the tablet. Needless to say, even when the terminal 60 is arranged at the upper center of the back surface, the image can be similarly taken only by changing the mounting angle of the tablet terminal 60 on the stage 411.

  According to the above-described embodiment, since the illumination device that illuminates the open book is installed on the lower surface of the stage 411 for mounting the imaging device so that the imaging direction faces the open book, Necessary lighting can be easily provided.

  In addition, according to the present embodiment, the illumination device 45 having the light emitting element is provided on the lower surface of the stage 411 so as to surround the opening formed along the longitudinal direction of the stage 411. Can be provided easily.

  Further, according to the present embodiment, the lamp shade that diffuses the light from the light emitting element 45 of the illumination device 45 is provided, so that the illuminance of the irradiation light can be made substantially uniform on the page P of the book B.

  Further, according to the present embodiment, the upper surface of the stage 411 is arranged so that the tablet terminal 60 faces the book B opened from the opening 412 formed in the stage 411 so that the imaging direction by the camera unit 62 of the tablet terminal 60 is directed. Therefore, it is possible to take an image of the page P of the book B that has been irradiated with sufficient irradiation light by the illumination device 45.
