The manner of forming the first joint 5a and the second joint 5b will be described with reference to FIG.

  First, the coil spring 23 is externally inserted into each cylindrical portion 21a provided on the inner side surface of the main arm 21. The auxiliary arm 22 is arranged to face the main arm 21 so as to sandwich the pair of coil springs 23 between the main arm 21 and the main arm 21.

  Subsequently, the first shaft portion 50a provided on the first support portion side engaging portion 52a is formed by a pair of through holes H22, H21 overlapped on the lower end side, specifically, a cylindrical member on the lower end side of the auxiliary arm 22. The shaft is sequentially passed through the portion 22a and the cylindrical portion 21a on the lower end side of the main arm 21. Similarly, the second shaft portion 50b provided in the second support portion side engaging portion 52b is formed by a pair of through holes H22, H21 overlapped on the upper end side, specifically, a cylinder on the upper end side of the auxiliary arm 22. The shaft is sequentially passed through the portion 22a and the cylindrical portion 21a on the upper end side of the main arm 21. Thereby, each of the pair of engaging portions 51a and 52a and the pair of engaging portions 51b and 52b is arranged with the surfaces on which the uneven structure is formed facing each other.

  Here, a step portion 521 is provided in the middle of the first shaft portion 50a and the second shaft portion 50b, and the front end side has a smaller diameter than the base end side. Specifically, the outer diameter of a portion on the distal end side of the step portion 521 is slightly smaller than the inner diameter of the cylindrical portion 21a on the main arm 21 side, and is configured to be insertable into the cylindrical portion 21a. ing. On the other hand, the outer diameter of a portion closer to the base end than the step portion 521 is larger than the inner diameter of the cylindrical portion 21a and smaller than the inner diameter of the cylindrical portion 22a on the auxiliary arm 22 side. Although it can be inserted into the cylindrical portion 22a on the side of the main arm 21, it is configured not to be inserted into the cylindrical portion 21a on the side of the main arm 21. Therefore, when the first shaft portion 50a and the second shaft portion 50b are passed through the shaft, the step portion 521 comes into contact with the distal end surface of the cylindrical portion 21a on the main arm 22 side.

  Subsequently, the group of members 52 a, 52 b, 21 to 23 has its lower end disposed between a pair of projecting wall portions 112 of the leg 11, and its upper end formed by the pair of projecting walls of the mounting plate 31. It is in a state of being disposed between the walls 312 and 312. At this time, the first supporting portion side engaging portion 52a accommodates a convex portion (not shown) formed on the protruding wall portion 112 of the leg 11 in a notch provided in the disk portion. It is arranged in such a position. Thereby, the first support portion side engaging portion 52a is non-rotatably locked to the protruding wall portion 112 (therefore, the arm support portion 1). Similarly, the projection (not shown) formed on the protruding wall portion 312 of the mounting plate 31 is accommodated in a notch provided in the disk portion of the second support portion side engaging portion 52b. It is arranged at such a position. As a result, the second support portion-side engaging portion 52b is non-rotatably locked to the protruding wall portion 312 (therefore, the tablet support portion 3).

  Subsequently, screws 501a are inserted one after another into the through hole H11 of one protruding wall portion 112, the inside of the shaft of the first shaft portion 50a, and the through hole H11 of the other protruding wall portion 112, and fastened with a nut 502a. Thus, the main arm 21, the auxiliary arm 22, and the arm support 1 are supported by the first shaft 50a. After fastening with the screw 501a and the nut 502a, the cap 112a is covered from the outer surface of the protruding wall portion 112. However, it is preferable that a sufficient tightening force is applied to the first shaft portion 50a so that the first support portion side engaging portion 52a is sufficiently urged against the protruding wall portion 112. Thereby, it is ensured that the engagement between the notch portion of the first support portion side engaging portion 52a and the convex portion of the protruding wall portion 112 is not released.

  Similarly, screws 501b are inserted one after another into the through hole H31 of one protruding wall portion 312, the inside of the shaft of the second shaft portion 50b, and the through hole H31 of the other protruding wall portion 312, and fastened with the nut 502b. Thus, the main arm 21, the auxiliary arm 22, and the tablet support 3 are pivotally supported by the second shaft 50b. Also here, it is preferable that a sufficient tightening force is applied to the second shaft portion 50b so that the second support portion side engaging portion 52b is sufficiently urged against the projecting wall portion 312.

  As described above, the portion of the first shaft portion 50a or the second shaft portion 50b closer to the base end than the step portion 521 is inserted into the cylindrical portion 22a on the auxiliary arm 22 side. Here, the outer diameter of the base end portion is smaller than the inner diameter of the cylindrical portion 22a on the auxiliary arm 22 side, and the auxiliary arm 22 is supported by the shaft portions 50a and 50b. Is movable in the axial direction. Specifically, the auxiliary arm 22 can move in the same axial direction with respect to the two shaft portions 50a and 50b (that is, move close to and away from the main arm 21 while maintaining a posture substantially parallel to the main arm 21). In addition, it is possible to move in the axial direction opposite to each of the shaft portions 50a and 50b (that is, to take a posture inclined with respect to the main arm 21). On the other hand, a step portion 521a abuts on the main arm 21 and is restricted so that it cannot move in the axial direction when the main arm 21 is supported by the shaft portions 50a and 50b. By restricting the movement of the main arm 21 in the axial direction, a sufficiently wide range in which the auxiliary arm 22 can be displaced is secured. As will be apparent below, the displacement of the auxiliary arm 22 with respect to the main arm 21 switches the inhibition / permission of the rotation of each joint 5a, 5b.

<3. Mode of use>
The mode of use of the tablet stand 100 will be described with reference to FIGS. 1 to 6 and FIG. FIG. 7A is an enlarged view of a main part of the tablet stand 100 in a state where neither the first operation S1 nor the second operation S2 is performed. FIG. 7B is an enlarged view of a main part of the tablet stand 100 in a state where the first operation S1 is being performed. FIG. 7C is an enlarged view of a main part of the tablet stand 100 in a state where the second operation S2 is being performed.

  As described above, the main arm 21 and the auxiliary arm 22 are urged in a direction away from each other by the pair of coil springs 23,23. Thus, the first arm portion side engaging portion 51a and the second arm portion side engaging portion 51b provided on the auxiliary arm 22 are combined with the first support portion side engaging portion 52a provided on the arm supporting portion 1 and the tablet. The pair of engaging portions 51a, 52a are urged toward the second supporting portion-side engaging portion 52b provided on the supporting portion 3 so that the concavo-convex structure formed on each of the opposing main surfaces of the pair of engaging portions 51a, 52a is engaged. The concavo-convex structures formed on the opposing main surfaces of the pair of engaging portions 51b, 52b mesh with each other. In this state, even if an external force is applied to the arm 2 and the arm support 1, the relative angles of the engaging portions 51a and 52a are not changed. Even if an external force is applied to the arm 2 and the tablet support 3, the relative angles of the engaging portions 51b and 52b are not changed. That is, the rotation of the first joint 5a and the rotation of the second joint 5b are both prohibited, the arm 2 and the arm support 1 cannot rotate with each other, and the arm 2 and the tablet support 3 also rotate. Cannot rotate with each other.

  When the user performs the first operation S1 on the tablet stand 100 in a state in which the rotation of the first joint 5a and the second joint 5b is prohibited, each rotation of the first joint 5a and the second joint 5b is performed. The action is individually switched from the prohibited state to the allowed state. When the user performs the second operation S2, the rotation of both the first joint 5a and the second joint 5b is switched from the prohibited state to the allowable state. Hereinafter, the operations S1 and S2 will be described.

(First operation)
The first operation S1 is an operation on the auxiliary arm 22 in the vicinity of the first joint 5a or the vicinity of the second joint 5b. Specifically, the first operation S1 is an operation of pressing the operation protrusion 2211 of the operation reception unit 221. is there.

  That is, in FIG. 7A in which the operation is not performed, as illustrated in FIG. 7B, the user, for example, operates the upper operation protrusion 2211 of the operation reception unit 221 (ie, the second operation protrusion 2211). When the joint 5b is pressed against the urging force of the upper coil spring 23, the auxiliary arm 22 engages with the first arm-side engaging portion 51a (ie, the first support-portion engaging portion 52a). With the first arm portion side engaging portion 51a) serving as a fulcrum, the upper end rotates in a direction approaching the main arm 21. When the auxiliary arm 22 rotates in such a direction, the lower contact convex portion 225 contacts the main arm 21 at a certain rotation angle, and the auxiliary arm 22 cannot rotate any more. Therefore, the entire arm cannot be slid in the direction approaching the main arm 21. That is, where the auxiliary arm 22 and the main arm 21 come into contact with each other via the contact convex portion 225, further movement of the auxiliary arm 22 is restricted.

  When the upper operation convex portion 2211 is pressed and the auxiliary arm 22 rotates, the second arm portion side engaging portion 51b is disengaged from the second support portion side engaging portion 52b. On the other hand, the first arm portion side engaging portion 51a is still urged toward the first support portion side engaging portion 52a by the urging force of the lower coil spring 23, and the pair of engaging portions 51a, 52a is maintained in an engaged state. In other words, the rotation of the second joint 5b is allowed (that is, the rotation of the arm 2 with respect to the tablet support unit 3), and the rotation of the first joint 5a is prohibited (that is, the arm 2). Of the arm support 1 is prohibited). As described above, since the range in which the auxiliary arm 22 can be displaced is widened here, the auxiliary arm 22 can rotate (that is, tilt) at a sufficiently large angle. Therefore, the rotation of the second joint 5b is reliably permitted. Further, when the auxiliary arm 22 and the main arm 21 come into contact via the upper contact convex portion 225, even if the user continues to apply a strong pressing force to the operation convex portion 2211, the auxiliary arm 22 Above, neither can rotate, nor can it slide entirely in the direction approaching the main arm 21. Therefore, the disengagement of the engaging portions 51a and 52a on the side that is not pressed is reliably avoided. Accordingly, the rotation of the first joint 5a is reliably prohibited while the rotation of the second joint 5b is reliably permitted.

  Further, in a state where the operation shown in FIG. 7A is not performed, for example, the user moves the lower operation convex portion 2211 (that is, the vicinity of the second joint 5a) of the operation receiving portion 221 downward. When the auxiliary arm 22 is pressed against the urging force of the side coil spring 23, the auxiliary arm 22 engages with the second arm portion side engaging portion 51b (that is, the second arm portion side engaged with the second support portion side engaging portion 52b). The lower end pivots in a direction approaching the main arm 21 with the engaging portion 52b) as a fulcrum. Here, as described above, a pair of contact protrusions 225 and 225 are formed on the inner side surface of the auxiliary arm 22, and the contact protrusion 225 is formed at the distance between the auxiliary arm 22 and the main arm 21. Some parts are smaller (narrower) than other parts. When the auxiliary arm 22 rotates in a direction in which the lower end side approaches the main arm 21, the lower contact protrusion 225 contacts the main arm 21 at a certain rotation angle, and the auxiliary arm 22 rotates further. And cannot slide in the direction approaching the main arm 21 as a whole. That is, where the auxiliary arm 22 and the main arm 21 come into contact with each other via the contact convex portion 225, further movement of the auxiliary arm 22 is restricted.

  When the lower operation convex portion 2211 is pressed and the auxiliary arm 22 rotates, the first arm portion side engaging portion 51a is disengaged from the first support portion side engaging portion 52a. On the other hand, the second arm portion side engaging portion 51b is still urged toward the second support portion side engaging portion 52b by the urging force of the upper coil spring 23, and the pair of engaging portions 51b, 52b Are maintained in an engaged state. That is, the rotation of the first joint 5a is allowed (that is, the rotation of the arm 2 with respect to the arm support 1) is allowed, and the rotation of the second joint 5b is prohibited (that is, the arm 2). Of the tablet supporting portion 3 is prohibited). At this time, as the rotation angle (that is, the inclination angle) of the auxiliary arm 22 increases, the separation distance between the pair of engagement portions 51a, 52a increases. Since the range in which the auxiliary arm 22 can be displaced is widened by restricting the movement in the axial direction, the auxiliary arm 22 can rotate (that is, tilt) at a sufficiently large angle. Therefore, the rotation of the first joint 5a is reliably allowed. On the other hand, when the pressing position is relatively close to the center, or when the length of the arm portion 6 is relatively short, the auxiliary arm 22 rotates as a whole in the direction approaching the main arm 21 while rotating. There is a possibility of sliding, and in this case, not only the engagement of the pair of engagement portions 51a and 52a but also the engagement of the other engagement portions 51b and 52b may be released. However, here, when the auxiliary arm 22 and the main arm 21 abut via the lower contact convex portion 225, even if the user continues to apply a strong pressing force to the operation convex portion 2211, the auxiliary arm 22 Cannot rotate any further, and cannot slide as a whole in the direction approaching the main arm 21. Therefore, the disengagement of the engaging portions 51b and 52b on the side that is not pressed is reliably avoided. Accordingly, the rotation of the second joint 5b is reliably prohibited while the rotation of the first joint 5a is reliably permitted.

  As described above, the tablet stand 100 is configured such that, upon receiving the first operation S1, the rotation of each of the first joint 5a and the second joint 5b is individually switched from the prohibited state to the permitted state. Therefore, the user changes the angle between the arm 2 and the arm support 1 (specifically, the leg 11) while pressing the lower operation projection 2211, and the angle becomes a desired angle. By stopping the pressing in this state, only the angle between the arm 2 and the arm support 1 can be changed to a desired angle without changing the angle between the arm 2 and the tablet support 3. Further, the user changes the angle between the arm portion 2 and the tablet support portion 3 (specifically, the mounting plate 31) while pressing the upper operation convex portion 2211, and the angle becomes a desired angle. By stopping the pressing in this state, only the angle between the arm 2 and the tablet support 3 can be changed to a desired one without changing the angle between the arm 2 and the arm support 1.

(Second operation)
The second operation S2 is an operation on the center or the vicinity of the first joint 5a and the second joint 5b on the auxiliary arm 22. Specifically, the second operation S2 presses the central flat portion 2212 on the top surface of the operation receiving portion 221. Operation.

  That is, in a state where the operation shown in FIG. 7A is not performed, as shown in FIG. 7C, the user pushes the central flat portion 2212 of the operation receiving portion 221 to the pair of coil springs 23, 23. When the auxiliary arm 22 is pressed against the urging force, the auxiliary arm 22 moves in a direction approaching the main arm 21 while maintaining a posture substantially parallel to the main arm 21. That is, both the upper end and the lower end of the auxiliary arm 22 are displaced in a direction approaching the main arm 21. Here, both the pair of contact projections 225 and 225 contact the main arm 21 substantially simultaneously, and the auxiliary arm 22 is regulated so as to be in a posture substantially parallel to the main arm 21. Will be displaced in a direction approaching.

  Then, while the 1st arm part side engaging part 51a dissociates from the 1st support part side engaging part 52a, the 2nd arm part side engaging part 51b also dissociates from the 2nd support part side engaging part 52b. That is, the rotation of the first joint 5a and the rotation of the second joint 5b are both allowed. As described above, since the range in which the auxiliary arm 22 can be displaced is widened here, the auxiliary arm 22 can be displaced by a sufficiently large distance along the axial direction. That is, both the pair of engaging portions 51a and 52a and the pair of engaging portions 51b and 52b can be sufficiently dissociated. Therefore, the rotation of the first joint 5a and the second joint 5b is reliably permitted.

  As described above, the tablet stand 100 is configured such that, upon receiving the second operation S2, both the rotation of the first joint 5a and the rotation of the second joint 5b are switched from the prohibited state to the permitted state. Accordingly, the user changes the angle between the arm 2 and the arm support 1 while pressing the central flat portion 2212 of the operation reception unit 221, and also changes the angle between the arm 2 and the tablet support 3. When the angles become the desired ones, the pressing is stopped, so that the angle between the arm part 2 and the arm supporting part 1 and the angle between the arm part 2 and the tablet supporting part 3 can be changed to the desired angle at a time. Can be changed to

  As described above, by performing the first operation S1 and / or the second operation S2, the user of the tablet stand 100 can easily perform the operations of the angle between the arm unit 2 and the arm support unit 1 and the angle between the arm unit 2 and the arm unit 2. The position and posture (angle) of the tablet M can be made desired by adjusting the angles of the tablet support portions 3 respectively.

  8 and 9 are a perspective view and a side view showing a state where the tablet stand 100 is folded. As described above, the tablet stand 100 is connected to the tablet support unit 3, the arm unit 2 connected to the tablet support unit 3 via the second joint 5b, and connected to the arm unit 2 via the first joint 5a. Arm support 1. In FIG. 2, the upper end of the back surface of the mounting plate 31 is rotated in a direction approaching the main arm 21 and the auxiliary arm 22 through the second joint 5b, and the upper surface of the leg 11 is moved through the first joint 5a. When rotated in a direction approaching the main arm 21 and the auxiliary arm 22, the arm support 1, the arm 2, and the tablet support 3 are folded as shown in FIGS. That is, the leg 11 is pushed down to the side of the arm 2 so that the two are parallel to each other, and a portion of the arm 2 above the second joint 5 b is accommodated in the concave portion 111 of the leg 11. And Further, the mounting plate 31 is pushed down toward the arm portion 2 to make them substantially parallel. As a result, the tablet stand 100 is in a folded state.

  In the holding member 32, the tablet press 323 is movable together with the tablet load receiving portion 322, and in a state where the arm support portion 1, the arm portion 2, and the tablet support portion 3 are folded, the tablet load receiving portion 322 31 can be arranged on the back side. Therefore, the tablet load receiving portion 322 is accommodated in the concave portion 113 provided at the lower end of the leg 11, and the tablet pressing portion 323 becomes substantially the same surface as the mounting plate 31.

  Further, from the folded state, the upper end of the back surface of the mounting plate 31 is rotated in a direction away from the main arm 21 and the auxiliary arm 22 via the second joint 5b, and the upper surface of the leg 11 is moved to the first joint. When it is rotated in a direction away from the main arm 21 and the auxiliary arm 22 via 5a, the arm support 1, the arm 2, and the tablet support 3 are deployed as shown in FIG.

  FIG. 10 is a diagram for explaining a method of mounting the tablet T on the tablet stand 100. As described above, when no external force acts on the holding member 32, the holding member 32 swings by its own weight around the cylindrical projection 312a as a rotation axis, and as shown in FIG. It is pressed against the lower end of the placing plate 31. Therefore, to mount the tablet T, the tablet load receiving portion 322 is lifted against its own weight as shown in FIG. Open t.

  In this state, as shown in FIG. 10B, the tablet T is inserted into the tablet insertion slot t, and the lower end of the tablet T is brought into contact with the tablet load receiving portion 322.

It moves in the direction in which it comes into close contact with 31. That is, when the tablet load receiving portion 322 receives the load of the tablet T and falls, the tablet retainer 323 moves toward the placing plate 31, and the distance between the tablet retainer 323 and the placing plate 31 decreases.

  FIG. 11 is a diagram illustrating a state where the tablet T is mounted on the tablet stand 100. The lower end of the tablet T on the mounting plate 31 is pressed toward the mounting plate 31 by the tablet holder 323 of the holding member 32.

  As described above, the recess 113 is provided at the lower end of the leg 11 of the arm support 1. Therefore, as shown in FIG. 12, the smartphone C as a lighting device is leaned on the lower wall of the recess 113, and the lower edge of the smartphone C is locked by the lower wall of the recess 113. When the light of the smartphone C is turned on, the illumination is applied from below the user facing the tablet T supported by the tablet support 3. Therefore, for example, when performing a video call or a self-portrait using the tablet T supported on the tablet stand 100, the user can illuminate the camera from below the face to improve the camera image. The same applies to the case where a penlight or the like is inserted into a through hole formed in the leg 11 of the arm support portion 1 and the penlight is turned on.

<< 2nd Embodiment >>
The configuration of the tablet support device 103 according to the second embodiment will be described with reference to FIGS. FIG. 13 is a front perspective view of the tablet support device 103 according to the second embodiment. FIG. 14 is a longitudinal sectional view of the tablet support device 103. FIGS. 13A and 14A show a state in which the tablet holding member 132 (hereinafter, holding member 132) is housed in the panel 131. FIGS. 13B and 14B show the holding state. The member 132 is in a state of being pulled out from the panel 131. FIG. 15 is an exploded perspective view of a main part of the tablet support device 103. FIG. 16 is a diagram illustrating a state in which the tablet T is supported by the tablet support device 103.

  As shown in FIGS. 13 to 15, the tablet support device 103 includes a panel 131 as a tablet receiving section and a holding member 132. The holding member 132 is a member for holding the tablet T placed on the surface of the panel 131 so as not to drop.

  The panel 131 is, for example, a desktop panel, and is a rectangular plate-shaped member. One main surface (front surface) of panel 131 forms a mounting surface on which tablet T is mounted. As shown in FIG. 15, a through-hole 1311 penetrating from the front surface to the rear surface is formed in the panel 131. The through-hole 1311 has a substantially rectangular vertical cross-sectional shape parallel to the surface of the panel 131, and is inclined downward from the surface of the panel 131 toward the rear surface. In the vicinity of the lower ends of the left and right inner walls of the through hole 1311, a pair of concave engaging grooves 1311a facing outward are formed. The pair of engagement grooves 1311a extend from the front surface to the rear surface of the panel 131.

  The holding member 132 is formed of a transparent material, and has a tablet load receiving portion 1321 and a tablet retainer 1322 as shown in FIG.

  The tablet load receiving portion 1321 is a member having substantially the same width as the through hole 1311 of the panel 131. The tablet load receiving portion 1321 is a portion that receives a load of the tablet T when the tablet T is mounted on the tablet support portion 103. At both ends of the tablet load receiving portion 1321, engagement portions 1321a to be engaged with a pair of engagement grooves 1311a formed on left and right inner walls of the through hole 1311 of the panel 131 are formed. The tablet load receiving portion 1321 is configured to be slidable in a state where the engaging portion 1321a is engaged with the pair of engaging grooves 1311a. Therefore, when the tablet load receiving portion 1321 receives the load of the tablet T, the tablet load receiving portion 1321 performs a sliding operation in a state of being engaged with the pair of engagement grooves 1311a.

  The tablet press 1322 is a portion formed of a transparent material that presses the tablet T on the panel 131 rearward, and extends to extend vertically from the tip of the tablet load receiving portion 1321. The tablet retainer 1322 has a substantially rectangular plate shape, and has a size to cover the through hole 1311 of the panel 131. Therefore, the tablet retainer 1322 is formed integrally with the tablet load receiving portion 1321, and performs a sliding operation together with the tablet load receiving portion 1321 in a state parallel to the surface of the panel 131. The tablet retainer 1322 has substantially the same width as the through hole 1311 of the panel 131. Therefore, in a state where the tablet T is mounted, the tablet retainer 1322 presses the tablet T toward the panel 131 in a state substantially parallel to the tablet T. That is, the tablet retainer 1322 is movable together with the tablet load receiving portion 1321, and moves in a direction in which the tablet T comes into close contact with the panel 131 when the tablet load receiving portion 1321 receives the load of the tablet T and descends. The pressing force of the tablet press 1322 changes according to the weight of the tablet T received by the tablet load receiving portion 1321. That is, the pressing force of the tablet retainer 1322 increases as the weight of the tablet T increases.

  As described above, the holding member 132 is slidably supported in the through hole 1311 of the panel 131. However, when no external force is applied, the holding member 132 slides rearward due to its own weight, and the tablet holder 1322 As shown in FIG. 13 (a), is disposed substantially flush with the surface of the panel 131 so as to cover the through hole 1311 of the panel 131. At this time, the upper end of the tablet retainer 1322 is pressed against the surface of the panel 131. Therefore, in order to mount the tablet T, as shown in FIG. 13B, the tablet holder 1324 is lifted up against its own weight, and when the holding member 132 is slid obliquely upward, the tablet holder 1322 The tablet insertion port t opens between the panel 131 and the panel 131.

  In this state, the tablet T is inserted into the tablet insertion slot t, and the lower end of the tablet T is brought into contact with the tablet load receiving portion 1321. Thereafter, when the tablet T is released, the tablet load receiving portion 1321 receives the load of the tablet T and falls, so that the tablet retainer 1322 moves in a direction in which the tablet T is brought into close contact with the panel 131 as shown in FIG. That is, when the tablet load receiving portion 1321 receives the load of the tablet T and falls, the tablet retainer 1322 moves toward the panel 131, and the distance between the tablet retainer 1322 and the panel 131 decreases. In this manner, by attaching the tablet T, the contact portion A between the tablet T and the tablet retainer 1322 approaches the panel 131, and the tablet retainer 1322 is configured to make the tablet T adhere to the panel 131.

<Effect>
According to the tablet support device 103 according to the above embodiment, the same effects as those of the tablet support unit 3 according to the first embodiment can be obtained.

  In the tablet support section 103 according to the embodiment, the tablet press 1324 performs a sliding operation together with the tablet load receiving section 1323.

  According to this configuration, the configuration in which the tablet T is brought into close contact with the panel 131 by the tablet holder 1324 can be simplified.

<<< 3rd Embodiment >>>
The configuration of the tablet stand 200 according to the third embodiment will be described with reference to FIGS. FIG. 17 is a front perspective view of the tablet stand 200 according to the third embodiment. FIG. 18 is a diagram for explaining a method of mounting the tablet T on the tablet stand 100.

  The main difference between the tablet stand 200 according to the present embodiment and the tablet stand 100 according to the first embodiment is the configuration of the tablet support. In the configuration of the tablet stand 200 of the present embodiment, the description of the same configuration as the tablet stand 100 of the first embodiment will be omitted.

  The tablet support section 203 includes a mounting plate 31 as a tablet receiving section and a holding section 232. As shown in FIG. 17, the holding portion 232 is formed integrally with the mounting plate 31 at the lower end of the mounting plate 31. The holding section 232 is formed of a transparent material, and has a tablet holding support section 2321 and a tablet holding 2322. The tablet pressing support portion 2321 has a rectangular plate shape having substantially the same width as the mounting plate 31, and extends substantially vertically from the lower end of the mounting plate 31.

  The tablet press 2322 is a portion formed of a transparent material that presses the tablet T on the mounting plate 31 backward. The tablet press 2322 extends upward from the tip of the tablet press support 2321. Therefore, the tablet press 2322 is formed integrally with the tablet press support 2321. The tablet retainer 2322 has a rectangular plate shape having substantially the same width as the placement plate 31 and the tablet retainer support 2321. The thickness of the tablet retainer 2322 is smaller than the distal end 2322a than the proximal end 2322b. That is, the inner side surface (the surface facing the mounting plate 31) of the tablet retainer 2322 is formed in a tapered shape in which the distal end 2322a is separated from the mounting plate 31 more than its base end 2322b.

  When mounting the tablet T, as shown in FIG. 18A, the lower end of the tablet T is inserted into a tablet insertion opening t formed between the tablet retainer 2322 and the mounting plate 31. Then, after the lower end of the tablet T contacts the inner surface of the tip side 2322a of the tablet retainer 2322, the tablet T moves downward along the inner surface of the tablet retainer 2322 by its own weight. Thereafter, the lower end of the tablet T comes into contact with the inner surface of the base end 2322b of the tablet retainer 2322, and the thickness of the lower end of the tablet T depends on the distance between the inner surface of the tablet retainer 2322 and the mounting plate 31. Move down until they are approximately the same. Therefore, when the tablet T is mounted, the tablet T is guided by the tablet holder 2322 and moves in a direction in which the tablet T comes into close contact with the mounting plate 31. That is, the distance between the inner surface of the tablet retainer 2322 and the mounting plate 31 decreases from the distal end 2322a of the tablet retainer 2322 toward the proximal end 2322b. In this manner, by mounting the tablet T, the contact portion A between the tablet T and the tablet retainer 2322 approaches the mounting plate 31, and the tablet retainer 2322 is configured to bring the tablet T into close contact with the mounting plate 31. You.
