Here, the outer diameter of the base end portion is smaller than the inner diameter of the cylindrical portion 221 on the auxiliary arm 22 side, and the auxiliary arm 22 is pivotally supported by the shaft portions 40a and 40b. is movable in the axial direction. Specifically, the auxiliary arm 22 can also move in the same axial direction with respect to the shafts 40a and 40b (that is, move toward and away from the main arm 21 while remaining substantially parallel to the main arm 21). It is also possible to move in the opposite axial direction with respect to each of the shafts 40a and 40b (that is, take an inclined posture with respect to the main arm 21). On the other hand, a step portion 421 abuts against the main arm 21, and is restricted so as not to move in the axial direction while being supported by the respective shaft portions 40a and 40b. By restricting the movement of the main arm 21 in the axial direction, the tablet T can be stably held without rattling, and a sufficiently wide range in which the auxiliary arm 22 can be displaced is ensured. As will be apparent below, by displacing the auxiliary arm 22 with respect to the main arm 21, prohibition/permission of rotation of the joints 4a and 4b are switched.

<3. Manner of Operation>
Modes of operation of the tablet stand 100 will be described with reference to FIGS. 8 to 11 in addition to FIGS. 1 to 7. FIG. FIG. 8 is a rear view of the tablet stand 100 when neither the first operation S1 nor the second operation S2 is performed. FIG. 9 is a rear view of the tablet stand 100 in a state where the first operation S1 is being performed. FIG. 10 is a rear view of tablet stand 100 in a state where second operation S2 is being performed. FIG. 11(a) is an enlarged view of a main part of the tablet stand 100 when neither the first operation S1 nor the second operation S2 is performed. FIG. 11(b) is an enlarged view of a main part of the tablet stand 100 when the first operation S1 is being performed. FIG. 11(c) is an enlarged view of the main part of the tablet stand 100 when the second operation S2 is being performed.

As described above, the main arm 21 and the auxiliary arm 22 are biased away from each other by the pair of coil springs 23 , 23 . As a result, the first stand-side engagement portion 41a and the second stand-side engagement portion 41b provided on the auxiliary arm 22 are connected to the first support-side engagement portion 42a provided on the stand support portion 1 and the tablet. The uneven structures formed on the opposing main surfaces of the pair of engaging portions 41a and 42a are engaged with each other by being biased toward the second supporting portion side engaging portion 42b provided in the supporting portion 3. , the concave-convex structures formed on the opposing main surfaces of the pair of engaging portions 41b and 42b are engaged (FIG. 8). In this state, even if an external force is applied to the stand portion 2 and the stand support portion 1, the relative angles of the engaging portions 41a and 42a are not changed. Further, even if an external force is applied to the stand portion 2 and the tablet support portion 3, the relative angles of the engaging portions 41b and 42b are not changed. In other words, both the first joint 4a and the second joint 4b are prohibited from rotating, the stand portion 2 and the stand support portion 1 cannot rotate relative to each other, and the stand portion 2 and the tablet support portion 3 are also prevented from rotating. cannot rotate relative to each other.

When the user performs the first operation S1 on the tablet stand 100 in which the rotation of the first joint 4a and the second joint 4b is prohibited, the first joint 4a and the second joint 4b are rotated. movement is individually switched from prohibited to permitted. Further, when the user performs the second operation S2, the rotation of both the first joint 4a and the second joint 4b is switched from the prohibited state to the permitted state. Each of the operations S1 and S2 will be described below.

(First operation)
The first operation S1 is an operation on the auxiliary arm 22 near the first joint 4a or near the second joint 4b. It is an operation to

That is, for example, when the user presses the lower end of the operation receiving portion 222 (that is, the vicinity of the first joint 4a) against the biasing force of the lower coil spring 23, the auxiliary arm 22 moves to the first position. The second stand side engaging portion 41b (that is, the second stand side engaging portion 41b engaged with the second support side engaging portion 42b) is used as a fulcrum, and the lower end side rotates in a direction approaching the main arm 21. move. Here, as described above, a pair of contact protrusions 223, 223 are formed on the inner surface of the auxiliary arm 22, and the distance between the auxiliary arm 22 and the main arm 21 is defined by the contact protrusion 223. Some parts are smaller (narrower) than others. When the auxiliary arm 22 rotates in a direction in which the lower end side approaches the main arm 21, the lower contact protrusion 223 comes into contact with the main arm 21 at a certain rotation angle, and the auxiliary arm 22 rotates further. In addition, the main arm 21 cannot be entirely slid in a direction approaching it. That is, when the auxiliary arm 22 and the main arm 21 come into contact with each other via the contact protrusion 223, further movement of the auxiliary arm 22 is restricted.

When the lower end of the operation receiving portion 222 is pressed and the auxiliary arm 22 rotates, the first stand portion side engaging portion 41a is disengaged from the first support portion side engaging portion 42a. On the other hand, the second stand side engaging portion 41b is still biased toward the second support side engaging portion 42b by the biasing force of the upper coil spring 23, and the pair of engaging portions 41b, 42b remain engaged. That is, the rotation of the first joint 4a is allowed (that is, the rotation of the stand portion 2 with respect to the stand support portion 1 is allowed), and the rotation of the second joint 4b is prohibited (that is, the stand portion 2 is prohibited from rotating with respect to the tablet support portion 3). At this time, the greater the rotation angle (that is, the tilt angle) of the auxiliary arm 22, the greater the separation distance between the pair of engaging portions 41a and 42a. By restricting the movement in the axial direction, a wide range in which the auxiliary arm 22 can be displaced is ensured, so that the auxiliary arm 22 can rotate (that is, tilt) at a sufficiently large angle. Therefore, the rotation of the first joint 4a is reliably permitted. On the other hand, when the pressed position is relatively central or when the length of the stand portion 2 is relatively short, the auxiliary arm 22 rotates and moves toward the main arm 21 as a whole. There is a possibility of sliding, and if this happens, there is a possibility that not only one pair of engaging portions 41a and 42a but also the other engaging portion 41b and 42b will be disengaged. However, here, when the auxiliary arm 22 and the main arm 21 come into contact with each other via the lower contact convex portion 223, even if the user continues to apply a strong pressing force to the operation receiving portion 222, the auxiliary arm 22 will not move. cannot rotate any further, nor can it slide generally toward the main arm. Therefore, disengagement of the engaging portions 41b and 42b on the side not pressed is reliably avoided. As a result, the rotation of the second joint 4b is reliably prohibited while the rotation of the first joint 4a is reliably permitted.

Further, when the user presses the upper end of the operation receiving portion 222 (that is, the vicinity of the second joint 4b) against the biasing force of the upper coil spring 23, the auxiliary arm 22 moves to the first stand. The upper end side rotates in a direction approaching the main arm 21 with the unit side engaging portion 41a (that is, the first stand portion side engaging portion 41a engaged with the first support portion side engaging portion 42a) as a fulcrum. (Fig. 9). When the auxiliary arm 22 rotates in this direction, the upper contact protrusion 223 comes into contact with the main arm 21 at a certain rotation angle, and the auxiliary arm 22 cannot rotate further. It will be in a state where it cannot entirely slide in a direction approaching the main arm 21 either. That is, when the auxiliary arm 22 and the main arm 21 come into contact with each other via the contact protrusion 223, further movement of the auxiliary arm 22 is restricted.

When the upper end of the operation receiving portion 222 is pressed and the auxiliary arm 22 rotates, the second stand portion side engaging portion 41b is disengaged from the second support portion side engaging portion 42b. On the other hand, the first stand side engaging portion 41a is still biased toward the first support side engaging portion 42a by the biasing force of the coil spring 23 on the lower side. remain engaged. That is, the rotation of the second joint 4b is allowed (that is, the rotation of the stand portion 2 with respect to the tablet support portion 3 is allowed), and the rotation of the first joint 4a is prohibited (that is, the stand portion 2 is prohibited from rotating with respect to the stand support portion 1). As described above, since the range in which the auxiliary arm 22 can be displaced is wide, the auxiliary arm 22 can rotate (that is, tilt) at a sufficiently large angle. Therefore, the rotation of the second joint 4b is reliably permitted. Further, when the auxiliary arm 22 and the main arm 21 come into contact with each other via the upper contact convex portion 223, even if the user continues to apply a strong pressing force to the operation receiving portion 222, the auxiliary arm 22 will not move. It is not possible to rotate the above, nor is it possible to slide in a direction approaching the main arm 21 as a whole. Therefore, disengagement of the engaging portions 41a and 42a on the non-pressed side is reliably avoided. As a result, the rotation of the first joint 4a is reliably prohibited while the rotation of the second joint 4b is reliably permitted.

Thus, the tablet stand 100 is configured such that the rotation of each of the first joint 4a and the second joint 4b is individually switched from the prohibited state to the permitted state by receiving the first operation S1. Therefore, the user changes the angle between the stand portion 2 and the stand support portion 1 (specifically, the leg 12) while pressing the lower end portion of the operation receiving portion 222, for example, so that the angle becomes By stopping the pressing in the desired state, only the angle between the stand part 2 and the stand support part 1 is changed to the desired one without changing the angle between the stand part 2 and the tablet support part 3. be able to. Further, the user changes the angle between the stand portion 2 and the tablet support portion 3 (specifically, the mounting plate 31) while pressing the upper end portion of the operation receiving portion 222, and the angle is adjusted to the desired value. By stopping the pressing in a state in which the stand part 2 and the tablet support part 3 are formed, it is possible to change only the angle between the stand part 2 and the tablet support part 3 to a desired one without changing the angle between the stand part 2 and the stand support part 1. can.

(Second operation)
The second operation S2 is an operation performed on the auxiliary arm 22 at or near the center of the first joint 4a and the second joint 4b. is.

That is, when the user presses the central portion of the operation receiving portion 222 in the longitudinal direction against the urging force of the pair of coil springs 23, 23, the auxiliary arm 22 remains substantially parallel to the main arm 21, It moves toward the main arm 21 (Fig. 10). That is, both the upper end side and the lower end side of the auxiliary arm 22 are displaced in a direction toward the main arm 21 .

Then, the first stand side engaging portion 41a is disengaged from the first support side engaging portion 42a, and the second stand side engaging portion 41b is also disengaged from the second support side engaging portion 42b. That is, both the rotation of the first joint 4a and the rotation of the second joint 4b are permitted.

In this manner, the tablet stand 100 is configured such that the rotation of both the first joint 4a and the second joint 4b is switched from the prohibited state to the permitted state by receiving the second operation S2. Therefore, the user changes the angle between the stand portion 2 and the stand support portion 1 while pressing the central portion of the top surface of the operation reception portion 222, and also changes the angle between the stand portion 2 and the tablet support portion 3. By stopping the pressing when both angles are desired respectively, the angle between the stand portion 2 and the stand support portion 1 and the angle between the stand portion 2 and the tablet support portion 3 are adjusted to the desired values at once. can be changed to

<4. Mode of use>
A mode of use of the tablet stand 100 will be described with reference to FIGS. 1 to 4 and FIGS. 12 to 14. FIG. 12 and 13 are diagrams showing the tablet stand 100 in the unfolded posture. FIG. 14 shows the tablet stand 100 in a folded posture.

As described above, the tablet stand 100 is used, for example, by placing it on a flat installation surface G such as a desk in an office or at home. to use. In the tablet stand 100, the angle between the stand portion 2 and the stand support portion 1 and the angle between the stand portion 2 and the tablet support portion 3 are changed independently by the user performing the operations S1 and S2 described above. It is possible.

For example, the angle between the stand portion 2 and the stand support portion 1 and the angle between the stand portion 2 and the tablet support portion 3 are both adjusted to be sufficiently small, so that the tablet stand 100 can be placed in a folded posture. (Fig. 14). Further, by adjusting the angle between the stand portion 2 and the stand support portion 1 and/or the angle between the stand portion 2 and the tablet support portion 3 from the folded posture, the tablet stand 100 can be changed from the folded posture to the unfolded posture. (Figs. 1 to 4, 12, 13). In addition, by changing these angles in the deployed posture, the height of the tablet support 3 (and thus the height of the tablet T supported by it) and the posture of the tablet support 3 (and thus this ) can be changed. However, the "height of the tablet support part 3" here is the height of the tablet support part 3 with respect to the installation surface G, and the "posture of the tablet support part 3" is the angle of the tablet support part 3 with respect to the installation surface G. (the angle formed by the installation surface G and the mounting plate 31).

Specifically, for example, the user can change the posture of the tablet T supported by the tablet stand 100 by changing the angle between the stand portion 2 and the tablet support portion 3 in the tablet stand 100 in the unfolded posture. can. That is, when the user wants to change the posture of the tablet T, for example, the user performs the first operation S1 on the side of the second joint 4b. Then, the second joint 4b is allowed to rotate. In this state, by rotating the tablet support portion 3 around the second joint 4b and appropriately adjusting the angle formed by the stand portion 2 and the tablet support portion 3, the user can obtain the desired posture of the tablet T. can be of For example, the tablet T can be placed in a substantially vertical posture (solid line in FIG. 12), and from such a posture, the tablet support portion 3 can be rotated around the second joint 4b so that the stand portion 2 and the tablet can be separated from each other. By changing the angle of the support portion 3, the tablet T can be tilted backward (virtual line in FIG. 12). The former posture is suitable, for example, when the user wants to see the tablet T from the front, and the latter posture is suitable, for example, when the user wants to see the tablet T from diagonally above.

Furthermore, the user can change the height of the tablet T supported by the tablet stand 100 by changing the angle between the stand portion 2 and the stand support portion 1 in the tablet stand 100 in the unfolded posture. That is, when the user wants to change the height of the tablet T, for example, the user performs the first operation S1 on the side of the first joint 4a. Then, the first joint 4a is allowed to rotate. In this state, the user can adjust the height of the tablet T as desired by rotating the stand portion 2 around the first joint 4a and appropriately adjusting the angle formed by the stand portion 2 and the stand support portion 1. can be of

Moreover, when the user wants to change only the height of the tablet T without changing the posture of the tablet T, the user may perform the second operation S2. In this way, both the first joint 4a and the second joint 4b are allowed to rotate. In this state, the stand portion 2 is rotated around the first joint 4a and the tablet support portion 3 is rotated around the second joint 4b, so that the angle formed by the stand portion 2 and the stand support portion 1 and the stand By appropriately adjusting each of the angles formed by the portion 2 and the tablet support portion 3, the user can obtain the desired height without changing the posture of the tablet T (see the phantom line in FIG. 13). ).

On the other hand, the user changes the angle between the stand portion 2 and the tablet support portion 3 and the angle between the stand portion 2 and the stand support portion 1 in the tablet stand 100 in the unfolded posture, thereby unfolding the posture of the tablet stand 100. It can be changed from the posture to the folding posture. That is, when the user wants to change the tablet stand 100 from the unfolded posture to the folded posture, the user first slides the lower end of the support portion 13 closer to the first receiving portion 111 to move the support portion 13 parallel to the legs 12 . In this state, the leg 12 is rotated about the first receiving portion 111 together with the supporting portion 13 to push them down toward the base plate 11 . Subsequently, the user performs the second operation S2 to allow both the first joint 4a and the second joint 4b to rotate. In this state, the tablet support section 3 and the stand support section 1 are rotated in the same direction (clockwise direction in FIG. 3) AR1 with respect to the stand section 2. As shown in FIG. That is, the stand support portion 1 is rotated in the predetermined direction AR1 around the first joint 4a and brought closer to the stand portion 2 so that the stand portion 2 overlaps the stand support portion 1, more specifically, , substantially the entire one side of the stand portion 2 is accommodated in the concave portion 121 of the leg 12 . In addition, the tablet support part 3 is rotated in the predetermined direction AR1 around the second joint 4b and brought closer to the stand part 2, and the tablet support part 3 overlaps the other side of the stand part 2. Practically, the placing plate 31 and the other side of the stand portion 2 are in a state in which they overlap almost entirely. As a result, the tablet stand 100 is in the folded posture (FIG. 14). In this folded posture, the stand portion 2 is sandwiched between the tablet support portion 3 and the stand support portion 1 . Needless to say, the procedure is reversed, that is, the tablet support portion 3 and the stand support portion 1 are rotated with respect to the stand portion 2 in the direction opposite to the predetermined direction AR1 (counterclockwise direction in FIG. 14) AR2. By moving, the tablet stand 100 in the folded posture can be changed to the unfolded posture.

The folded posture is suitable when the tablet stand 100 is not used (during storage). As described above, in the tablet stand 100, the plane F including the tangent line of the second joint 4a is formed so as to substantially match the rear surface of the mounting plate 31 (FIG. 3). Since the placing plate 31 is arranged sufficiently close to each other, the thickness of the tablet stand 100 is sufficiently small in the folded posture, and it is difficult to take up space for storage. In addition, the second operation S2 is convenient for folding the tablet stand 100 (or unfolding the folded tablet stand 100). That is, by performing the second operation S2, both the first joint 4a and the second joint 4b are switched to a state in which rotation is permitted, and the parts 1, 2, and 3 are simultaneously rotated around the joints 4a and 4b. By doing so, the tablet stand 100 can be quickly folded (or unfolded).

<5. Effect>
As described above, the tablet stand 100 according to the above-described embodiment includes the tablet support portion 3 including the mounting plate 31 as a tablet receiving portion for receiving the tablet T, and the stand portion 2 that supports the tablet support portion 3 . The tablet support portion 3 and the stand portion 2 are configured to be changeable between a folded posture (FIG. 14) and an unfolded posture (FIG. 12, etc.) in which both are at least partially overlapped. Furthermore, the height and posture of the tablet support portion 3 with respect to the surface (installation surface) G on which the tablet stand 100 is installed can be changed. According to this configuration, not only the posture of the tablet T but also the support height of the tablet T can be adjusted.

The tablet stand 100 also includes a stand support section 1 that supports the stand section 2 . In the folded posture, the stand portion 2 and the stand support portion 1 are configured so as to overlap almost entirely. According to this configuration, the tablet support section 3 is supported by the stand section 2 and the stand support section 1, so that the tablet T can be stably supported. On the other hand, since the tablet support section 3, the stand section 2, and the stand support section 1 can be folded so as to overlap each other, the tablet stand 100 can be folded compactly.

Also, in the tablet stand 100 , the end of the stand support section 1 is connected to the end of the stand section 2 . The stand support portion 1 abuts on the installation surface G when placed on the installation surface G. As shown in FIG. According to this configuration, the tablet T can be stably supported with a simple configuration.

In the tablet stand 100, the tablet support section 3 and the stand section 2, and the stand section 2 and the stand support section 1 are connected via joints 4a and 4b, which are rotation shafts. Then, the change in posture between the folded posture and the unfolded posture, the change in the height of the tablet support portion 3, and the change in the angle of the tablet support portion 3 are rotations around the joints 4a and 4b, which are rotation axes. It is realized by According to this configuration, it is possible to change the posture between the folded posture and the unfolded posture, change the support height of the tablet T, or change the posture of the tablet T with a simple configuration.

In addition, in the tablet stand 100 , the plane F including the tangent line of the second joint 4 b that is the rotation axis substantially coincides with the rear surface of the mounting plate 31 . According to this configuration, since the second joint 4b and the mounting plate 31 are sufficiently close to each other, the entire tablet stand 100 can be downsized, and the tablet stand 100 can be folded compactly.

Further, the tablet stand 100 is provided with a clutch that prohibits or permits rotation of the joints 4a and 4b, which are rotary shafts, by engaging or disengaging radial teeth. According to this configuration, it is possible to prohibit/permit rotation around the joints 4a and 4b, which are rotation axes, with a simple configuration.

In the tablet stand 100, the stand portion 2 and the stand support portion 1 are connected via a first joint 4a that is a rotation shaft, and the tablet support portion 3 and the stand portion 2 are connected to each other via a second joint that is a rotation shaft. 4b, and the change in posture between the unfolded posture and the folded posture is realized by rotating the tablet support portion 3 and the stand support portion 1 in the same direction with respect to the stand portion 2. . Then, in the folded posture, the stand portion 2 is sandwiched between the tablet support portion 3 and the stand support portion 1 . According to this configuration, the posture can be smoothly changed between the unfolded posture and the folded posture, and the tablet stand 100 can be folded into a sufficiently compact size.

A first operation S<b>1 described later is an operation of pressing the operation convex portion 6211 , and a second operation S<b>2 is an operation of pressing the central flat portion 6212 . That is, each operation convex portion 6211 in the operation reception portion 621 configures the input portion for the first operation S1, and the central flat portion 6212 configures the input portion for the second operation S2.

A pair of protrusions (contact protrusions) 622 , 622 are formed on the inner surface of the auxiliary arm 62 so as to be spaced apart in the extending direction of the stand section 6 . Each contact protrusion 622 has a shape that protrudes compared to other portions, and serves as a constricted portion that narrows the distance between the main arm 61 and the auxiliary arm 62 . The pair of contact protrusions 622, 622 are formed such that their intermediate positions coincide with the intermediate positions between the first joint 8a and the second joint 8b. Each contact convex portion 622 is preferably formed at a position corresponding to the boundary between the central flat portion 6212 of the operation receiving portion 621 and each operation convex portion 6211 or in the vicinity thereof.

A pair of coil springs 63 , 63 are provided between the main arm 61 and the auxiliary arm 62 . Specifically, each coil spring 63 is externally inserted into each cylindrical portion 611 provided on the main arm 61 , and in this state, the auxiliary arm 62 and the main arm 61 sandwich the pair of coil springs 63 , 63 . Thus, it is arranged to face the main arm 61 . When the stand portion 6 is attached to the support portions 5 and 7, each coil spring 63 is contracted and contacts the inner surface of the auxiliary arm 62 at one end and the inner surface of the main arm 61 at the other end. abut. In other words, in this state, the main arm 61 and the auxiliary arm 62 are urged by the pair of coil springs 63, 63 in directions away from each other. That is, the pair of coil springs 63 , 63 serve as biasing portions that bias the auxiliary arm 62 away from the main arm 61 .

The support portion 64 is a long member extending in the same direction as the main arm 61 , and its upper end is fixed to the lower end of the main arm 61 . A long rod-shaped support rod 641 is provided at the lower end of the support portion 64 in such a posture that the long direction of the support rod 641 extends along the width direction of the support portion 64 . The support portion 64 and the main arm 61 are integrally formed, for example, by using an integral molding technique.

The first joint 8a will be described with continued reference to FIGS. 17 and 18. FIG. The first joint 8a is formed like a clutch. That is, the first joint 8a has an engaging portion (first stand portion-side engaging portion) 81a provided on the side of the stand portion 6 (specifically, the auxiliary arm 62) and an engaging portion 81a provided on the side of the stand support portion 5. provided engaging portion (first supporting portion side engaging portion) 82a. Both engaging portions 81a and 82a are rotatably supported by a shaft portion (first shaft portion) 80a, and the pair of engaging portions 81a and 82a engage/disengage to form the first joint. A state in which the rotation of the stand portion 8a (that is, the rotation of the stand portion 6 with respect to the stand support portion 5) is prohibited and a state in which the rotation is allowed can be switched.

The first stand side engaging portion 81a is integrally formed with the auxiliary arm 62 by using, for example, an integral molding technique. The first stand-side engaging portion 81a has an uneven structure provided so as to surround the through hole H62 (the through hole H62 formed on the lower end side) in the planar portion of the outer surface of the auxiliary arm 62. . Specifically, the concave-convex structure is formed by arranging rectangular convex portions (teeth) radially from the center of the through hole H62 over 360°.

The first support side engaging portion 82a is a substantially disc-shaped member having a pair of planar main surfaces. A cylindrical shaft portion (first shaft portion) 80a is integrally formed at the center of the first support side engaging portion 82a by using, for example, an integral molding technique. In addition, a concave-convex structure is provided on the main surface of the first supporting portion-side engaging portion 82a on the side where the first shaft portion 80a is formed. This concave-convex structure is provided around the first shaft portion 80a, and more specifically, a rectangular convex portion extends over 360° so as to form a radial shape from the center of the first shaft portion 80a. It is an array. A notch portion 822 is formed on the peripheral edge of the disk portion of the first support side engaging portion 82a.

<1-5. Second joint>
The second joint 8b will be described with continued reference to FIGS. 17 and 18. FIG. The second joint 8b is formed like a clutch like the first joint 8a. That is, the second joint 8b has an engaging portion (second stand portion side engaging portion) 81b provided on the stand portion 6 (specifically, the auxiliary arm 62) side and an engaging portion (second stand portion side engaging portion) 81b provided on the side of the tablet support portion 7. provided engaging portion (second supporting portion side engaging portion) 82b. Both the engaging portions 81b and 82b are rotatably supported by a shaft portion (second shaft portion) 80b, and the pair of engaging portions 81b and 82b engage/disengage to form the second joint. A state in which the rotation of the 8b (that is, the rotation of the stand portion 6 with respect to the tablet support portion 7) is prohibited and a state in which the rotation is allowed can be switched.

The second stand side engaging portion 81b is formed integrally with the auxiliary arm 62 by using, for example, an integral molding technique, like the first stand side engaging portion 81a. The second stand portion side engaging portion 81b has an uneven structure provided so as to surround the through hole H62 (the through hole H62 formed on the upper end side) in the planar portion of the outer surface of the auxiliary arm 62. . A specific configuration of the second stand side engaging portion 81b is the same as that of the first stand side engaging portion 81a.

The second support side engaging portion 82b is the same member as the first support side engaging portion 82a. That is, the second support side engaging portion 82b is a substantially disk-shaped member having a pair of planar main surfaces, and a cylindrical shaft portion (second shaft portion) 80b is integrally formed at the center. It is In addition, a concave-convex structure is provided on one main surface, and a notch portion 822 is formed on the peripheral edge of the disk portion.

<2. Formation Mode of Each Joint>
How the first joint 8a and the second joint 8b are formed will be described with reference to FIGS. 17 and 18. FIG.

First, the coil spring 63 is externally inserted in each cylindrical portion 611 provided on the inner surface of the main arm 61 . Further, the auxiliary arm 62 is arranged to face the main arm 61 with a pair of coil springs 63, 63 interposed therebetween.

Subsequently, the first shaft portion 80a provided on the first support side engaging portion 82a is inserted into a pair of through holes H62 and H61 that are overlapped on the lower end side, specifically, the cylinder on the lower end side of the auxiliary arm 62. and the cylindrical portion 611 on the lower end side of the main arm 61, in order. Similarly, the second shaft portion 80b provided in the second support portion side engaging portion 82b extends through a pair of through holes H62 and H61 that are overlapped on the upper end side, more specifically, through a cylinder on the upper end side of the auxiliary arm 62. , and the cylindrical portion 611 on the upper end side of the main arm 61, in order. As a result, the pair of engaging portions 81a and 82a and the pair of engaging portions 81b and 82b are arranged so that the surfaces on which the concave-convex structure is formed face each other.

Here, a stepped portion 821 is provided in the middle of the first shaft portion 80a and the second shaft portion 80b, and the tip side has a smaller diameter than the base end side. Specifically, the outer diameter of the portion on the distal end side of the stepped portion 821 is slightly smaller than the inner diameter of the cylindrical portion 611 on the main arm 61 side, and is configured to be insertable into the cylindrical portion 611 . ing. On the other hand, the outer diameter of the portion closer to the base end than the stepped portion 821 is larger than the inner diameter of the cylindrical portion 611 and smaller than the inner diameter of the cylindrical portion on the auxiliary arm 62 side. can be inserted into the cylindrical portion 611 of the main arm 61 but not into the cylindrical portion 611 on the main arm 61 side. Therefore, in a state in which the first shaft portion 80a and the second shaft portion 80b are passed through, the step portion 821 abuts against the tip surface of the cylindrical portion 611 on the main arm 61 side.

Subsequently, the group of members 82a, 82b, 61 to 63 are arranged at their lower ends between the pair of projecting walls 512, 512 of the leg 51, and their upper ends are arranged at the pair of mounting plates 71. is arranged between the protruding wall portions 712, 712. At this time, the first support side engaging portion 82a is arranged such that the projection formed on the projecting wall portion 512 of the leg 51 is accommodated in the notch portion 822 provided in the disk portion. placed in position. As a result, the first support side engaging portion 82a is non-rotatably locked to the projecting wall portion 512 (and thus to the stand support portion 5). Similarly, the projection 7121 formed on the projecting wall portion 712 of the mounting plate 71 is accommodated in the notch portion 822 provided in the disc portion of the second support side engaging portion 82b. placed in a similar position. As a result, the second support side engaging portion 82b is non-rotatably locked to the projecting wall portion 712 (and thus the tablet support portion 7).

Subsequently, screws 801a are successively inserted through the through hole H51 of one projecting wall portion 512, the shaft interior of the first shaft portion 80a, and the through hole H51 of the other projecting wall portion 512, and fastened with a nut 802a. As a result, the main arm 61, the auxiliary arm 62, and the stand support portion 5 are pivotally supported by the first shaft portion 80a. Thereby, the first joint 8a is formed. However, it is preferable that a sufficient tightening force is applied to the first shaft portion 80a so that the first support side engaging portion 82a is sufficiently biased against the projecting wall portion 512. As shown in FIG. This ensures that the engagement between the notch portion 822 of the first supporting portion-side engaging portion 82a and the convex portion of the projecting wall portion 512 is not released.

Similarly, the screws 801b are successively inserted through the through hole H71 of one projecting wall portion 712, the shaft interior of the second shaft portion 80b, and the through hole H71 of the other projecting wall portion 712, and fastened with a nut 802b. As a result, the main arm 61, the auxiliary arm 62, and the tablet support portion 7 are pivotally supported by the second shaft portion 80b. Thereby, the second joint 8b is formed. In this case as well, it is preferable that a sufficient tightening force is applied to the second shaft portion 80b so that the second support side engaging portion 82b is sufficiently biased against the projecting wall portion 712. As shown in FIG.

Here, for example, by appropriately adjusting the dimensions of each projecting wall portion 712 and the formation position of the through hole H71, the tangent line of the second joint 8b, specifically, the second stand portion side engaging portion 81b, can be adjusted. and a plane F including tangents of the disk portions of the second support side engaging portion 82b is formed so as to substantially match the rear surface of the mounting plate 71 (FIG. 16). As a result, the second joint 8b and the mounting plate 71 are arranged sufficiently close to each other, so that the overall size of the tablet stand 200 can be reduced, and the tablet stand 200 can be folded compactly in the folding posture described later. be able to.

As described above, the portion closer to the base end than the stepped portion 821 of the first shaft portion 80a or the second shaft portion 80b is inserted into the cylindrical portion on the auxiliary arm 62 side. Here, the outer diameter of the base end portion is smaller than the inner diameter of the cylindrical portion of the auxiliary arm 62 side, and the auxiliary arm 62 is pivotally supported by the shaft portions 80a and 80b. , is axially movable. Specifically, the auxiliary arm 62 can also move in the same axial direction with respect to both the shaft portions 80a and 80b (that is, move toward and away from the main arm 61 while remaining substantially parallel to the main arm 61). It is also possible to move in the opposite axial direction with respect to each of the shafts 80a and 80b (that is, take an inclined posture with respect to the main arm 61). On the other hand, a stepped portion 821 abuts against the main arm 61, and is restricted so as not to move in the axial direction while being supported by the respective shaft portions 80a and 80b. By restricting the movement of the main arm 61 in the axial direction, the tablet T can be stably held without rattling, and a sufficiently wide range in which the auxiliary arm 62 can be displaced is ensured. As will be apparent below, by displacing the auxiliary arm 62 with respect to the main arm 61, the prohibition/permission of rotation of the joints 8a and 8b is switched.

<3. Manner of Operation>
The mode of operation of tablet stand 200 will be described with reference to FIGS. 15 to 18. FIG.

As described above, the main arm 61 and the auxiliary arm 62 are biased away from each other by the pair of coil springs 63 , 63 . As a result, the first stand-side engagement portion 81a and the second stand-side engagement portion 81b provided on the auxiliary arm 62 are connected to the first support-side engagement portion 82a provided on the stand support portion 5 and the tablet. The uneven structures formed on the opposing main surfaces of the pair of engaging portions 81a and 82a are engaged with each other by being biased toward the second supporting portion-side engaging portion 82b provided on the supporting portion 7. , the concave-convex structures formed on the opposing main surfaces of the pair of engaging portions 81b and 82b are engaged. In this state, even if an external force is applied to the stand portion 6 and the stand support portion 5, the relative angles of the engaging portions 81a and 82a are not changed. Moreover, even if an external force is applied to the stand portion 6 and the tablet support portion 7, the relative angles of the engaging portions 81b and 82b are not changed. In other words, both the first joint 8a and the second joint 8b are prohibited from rotating, and the stand portion 6 and the stand support portion 5 cannot rotate relative to each other, and the stand portion 6 and the tablet support portion 7 are also prevented from rotating. cannot rotate relative to each other.

When the user performs the first operation S1 on the tablet stand 200 in which the rotation of the first joint 8a and the second joint 8b is prohibited, the first joint 8a and the second joint 8b are rotated. movement is individually switched from prohibited to permitted. Further, when the user performs the second operation S2, the rotation of both the first joint 8a and the second joint 8b is switched from the prohibited state to the permitted state. Each of the operations S1 and S2 will be described below.

(First operation)
The first operation S1 is an operation of the auxiliary arm 62 near the first joint 8a or near the second joint 8b. be.

That is, for example, when the user presses the lower operation convex portion 6211 (that is, the vicinity of the first joint 8a) of the operation reception portion 621 against the biasing force of the coil spring 63 arranged on the lower side, The auxiliary arm 62 has a second stand side engaging portion 81b (that is, the second stand side engaging portion 81b engaged with the second support side engaging portion 82b) as a fulcrum, and the lower end side is a main arm. It rotates in a direction approaching 61 . Here, as described above, a pair of contact protrusions 622, 622 are formed on the inner surface of the auxiliary arm 62, and the distance between the auxiliary arm 62 and the main arm 61 is defined by the contact protrusion 622. Some parts are smaller (narrower) than others. When the auxiliary arm 62 rotates in a direction in which the lower end side approaches the main arm 61, the lower contact protrusion 622 comes into contact with the main arm 61 at a certain rotation angle, and the auxiliary arm 62 rotates further. In addition, the main arm 61 cannot be entirely slid in the direction approaching it. In other words, when the auxiliary arm 62 and the main arm 61 come into contact with each other via the contact protrusion 622, further movement of the auxiliary arm 62 is restricted.

When the lower operation convex portion 6211 is pressed and the auxiliary arm 62 rotates, the first stand portion side engaging portion 81a is disengaged from the first support portion side engaging portion 82a. On the other hand, the second stand side engaging portion 81b is still biased toward the second support side engaging portion 82b by the biasing force of the upper coil spring 63, and the pair of engaging portions 81b, 82b remain engaged. That is, the rotation of the first joint 8a is allowed (that is, the stand portion 6 is allowed to rotate with respect to the stand support portion 5), and the rotation of the second joint 8b is prohibited (that is, the stand portion 6 is prohibited from rotating with respect to the tablet support portion 7). At this time, the greater the rotation angle (that is, the tilt angle) of the auxiliary arm 62, the greater the separation distance between the pair of engaging portions 81a and 82a. By restricting movement in the axial direction, a wide range in which the auxiliary arm 62 can be displaced is ensured, so that the auxiliary arm 62 can rotate (that is, tilt) at a sufficiently large angle. Therefore, the rotation of the first joint 8a is reliably permitted. On the other hand, when the pressing position is relatively central or when the length of the stand portion 6 is relatively short, the auxiliary arm 62 rotates and moves toward the main arm 61 as a whole. There is a possibility of sliding, and if this happens, not only the meshing of one pair of engaging portions 81a and 82a but also the meshing of the other engaging portion 81b and 82b may be released. However, here, when the auxiliary arm 62 and the main arm 61 come into contact with each other through the lower contact protrusion 622, even if the user continues to apply a strong pressing force to the operation protrusion 6211, the auxiliary arm 62 will cannot rotate any further, nor can it generally slide toward the main arm 61 . Therefore, disengagement of the engaging portions 81b and 82b on the side not pressed is reliably avoided. As a result, the rotation of the second joint 8b is reliably prohibited while the rotation of the first joint 8a is reliably permitted.

Further, for example, when the user presses the upper operation convex portion 6211 (that is, the vicinity of the second joint 8b) of the operation receiving portion 621 against the urging force of the upper coil spring 63, the auxiliary arm 62 moves to the second position. 1 stand portion side engaging portion 81a (that is, the first stand portion side engaging portion 81a engaged with the first support portion side engaging portion 82a) as a fulcrum, the upper end side rotates in a direction approaching the main arm 61. move. When the auxiliary arm 62 rotates in this direction, the upper contact protrusion 622 comes into contact with the main arm 61 at a certain rotation angle, and the auxiliary arm 62 cannot rotate further, and the main arm 62 rotates. It will be in a state where it cannot entirely slide in a direction approaching the arm 61 either. In other words, when the auxiliary arm 62 and the main arm 61 come into contact with each other via the contact protrusion 622, further movement of the auxiliary arm 62 is restricted.

When the upper operation convex portion 6211 is pressed to rotate the auxiliary arm 62, the second stand portion side engaging portion 81b is disengaged from the second support portion side engaging portion 82b. On the other hand, the first stand side engaging portion 81a is still biased toward the first support side engaging portion 82a by the biasing force of the coil spring 63 on the lower side. 82a remains engaged. That is, the rotation of the second joint 8b is allowed (that is, the stand portion 6 is allowed to rotate with respect to the tablet support portion 7), and the rotation of the first joint 8a is prohibited (that is, the stand portion 6 is prohibited from rotating with respect to the stand support portion 5). As described above, since the range in which the auxiliary arm 62 can be displaced is wide, the auxiliary arm 62 can rotate (that is, tilt) at a sufficiently large angle. Therefore, the rotation of the second joint 8b is reliably permitted. In addition, when the auxiliary arm 62 and the main arm 61 come into contact with each other via the upper contact projection 622, even if the user continues to apply a strong pressing force to the operation projection 6211, the auxiliary arm 62 will not move. It is not possible to rotate the above, nor is it possible to slide in a direction approaching the main arm 21 as a whole. Therefore, disengagement of the engaging portions 81a and 82a on the side not pressed is reliably avoided. As a result, the rotation of the first joint 8a is reliably prohibited while the rotation of the second joint 8b is reliably permitted.

Thus, the tablet stand 200 is configured such that the rotation of each of the first joint 8a and the second joint 8b is individually switched from the prohibited state to the permitted state by receiving the first operation S1. Therefore, the user can change the angle between the stand part 6 and the stand support part 5 (specifically, the leg 51) while pressing the lower operation convex part 6211 to obtain a desired angle. By stopping the pressing in this state, only the angle between the stand portion 6 and the stand support portion 5 can be changed as desired without changing the angle between the stand portion 6 and the tablet support portion 7.例文帳に追加Further, the user changes the angle between the stand portion 6 and the tablet support portion 7 (specifically, the mounting plate 71) while pressing the upper operation convex portion 6211, and the angle becomes the desired one. By stopping the pressing in this state, only the angle between the stand portion 6 and the tablet support portion 7 can be changed as desired without changing the angle between the stand portion 6 and the stand support portion 5.例文帳に追加

(Second operation)
The second operation S2 is an operation of the auxiliary arm 62 at or near the center of the first joint 8a and the second joint 8b. Operation.

That is, when the user presses the central flat portion 6212 of the operation receiving portion 621 against the urging force of the pair of coil springs 63 , 63 , the auxiliary arm 62 maintains a posture substantially parallel to the main arm 61 . Move toward 61. That is, both the upper end side and the lower end side of the auxiliary arm 62 are displaced toward the main arm 61 . Here, both of the pair of contact protrusions 622 , 622 contact the main arm 61 substantially simultaneously, and the auxiliary arm 62 is regulated to assume a posture substantially parallel to the main arm 61 .

Then, the first stand side engaging portion 81a is disengaged from the first support side engaging portion 82a, and the second stand side engaging portion 81b is also disengaged from the second support side engaging portion 82b. That is, both the rotation of the first joint 8a and the rotation of the second joint 8b are permitted. As described above, since the range in which the auxiliary arm 62 can be displaced is wide, the auxiliary arm 62 can be displaced by a sufficiently large distance along the axial direction. That is, both the pair of engaging portions 81a and 82a and the pair of engaging portions 81b and 82b can be fully disengaged. Therefore, the rotation of the first joint 8a and the second joint 8b is reliably allowed.

In this manner, the tablet stand 200 is configured such that the rotation of both the first joint 8a and the second joint 8b is switched from the prohibited state to the permitted state by receiving the second operation S2. Therefore, while pressing the central flat portion 6212 of the operation receiving portion 621, the user changes the angle between the stand portion 6 and the stand support portion 5, and also changes the angle between the stand portion 6 and the tablet support portion 7. By stopping the pressing when the desired angles are obtained, the angle between the stand portion 6 and the stand support portion 5 and the angle between the stand portion 6 and the tablet support portion 7 can be adjusted to the desired values at once. can be changed to

<4. Mode of use>
A mode of use of the tablet stand 200 will be described with reference to FIGS. 19 to 23 in addition to FIGS. 15 and 16. FIG. 19 to 22 are diagrams showing the tablet stand 200 in the unfolded posture. FIG. 23 shows the tablet stand 200 in the folded posture.

As described above, like the tablet stand 100 according to the first embodiment, the tablet stand 200 is used by placing it on a flat installation surface G such as a desk in an office or at home. and place it at a desired position on the installation surface G for use. In the tablet stand 200, the angle between the stand portion 6 and the stand support portion 5 and the angle between the stand portion 6 and the tablet support portion 7 can be changed independently by the user performing the operations S1 and S2 described above. It is possible.

For example, the angle between the stand portion 6 and the stand support portion 5 and the angle between the stand portion 6 and the tablet support portion 7 are both adjusted to be sufficiently small, so that the tablet stand 200 can be placed in the folded posture. (Fig. 23). Further, by adjusting the angle between the stand portion 6 and the stand support portion 5 and/or the angle between the stand portion 6 and the tablet support portion 7 from the folded posture, the tablet stand 200 can be changed from the folded posture to the unfolded posture. (Figs. 15, 16, 19-22). In addition, by changing these angles in the deployed posture, the height of the tablet support portion 7 (and thus the height of the tablet T supported by it) and the posture of the tablet support portion 7 (and thus this ) can be changed.

Specifically, for example, the user can change the posture of the tablet T supported by the tablet stand 200 by changing the angle between the stand portion 6 and the tablet support portion 7 in the tablet stand 200 in the unfolded posture. can. That is, when the user wants to change the posture of the tablet T, for example, the user performs the first operation S1 on the side of the second joint 8b. Then, the second joint 8b is allowed to rotate. In this state, by rotating the tablet support portion 7 around the second joint 8b and appropriately adjusting the angle formed by the stand portion 6 and the tablet support portion 7, the user can obtain the desired posture of the tablet T. can be of For example, the tablet T can be placed in a posture that is slightly tilted backward from a substantially vertical position (FIGS. 15 and 16). By changing the angle between the stand portion 6 and the tablet support portion 7, the tablet T can be slightly (about 10° to 15°) raised from the horizontal plane (FIGS. 19 and 20). The former posture is suitable for cases such as when the user wants to see the tablet T from obliquely above, and the latter posture is for the tablet T to be placed on the desk with the camera function of the tablet T configured including the camera function. This is suitable for cases such as when you want to image a document or the like.

Furthermore, the user can change the height of the tablet T supported by the tablet stand 200 by changing the angle between the stand portion 6 and the stand support portion 5 in the tablet stand 200 in the unfolded posture. That is, when the user wants to change the height of the tablet T, for example, the user performs the first operation S1 on the side of the first joint 8a. Then, the first joint 8a is allowed to rotate. In this state, the user can adjust the height of the tablet T to the desired height by rotating the stand portion 6 around the first joint 8a and appropriately adjusting the angle formed by the stand portion 6 and the stand support portion 5. can be of

Moreover, when the user wants to change only the height of the tablet T without changing the posture of the tablet T, the user may perform the second operation S2. In this way, both the first joint 8a and the second joint 8b are allowed to rotate. In this state, the stand portion 6 is rotated around the first joint 8a, and the tablet support portion 7 is rotated around the second joint 8b. By appropriately adjusting each of the angles formed by the portion 6 and the tablet support portion 7, the user can set the desired height of the tablet T without changing the posture thereof. For example, from the state shown in FIGS. 19 and 20, the angle formed by the stand portion 6 and the stand support portion 5 is adjusted while adjusting the angle formed by the stand portion 6 and the tablet support portion 7 so that the posture of the tablet T is maintained. is made sufficiently small and the stand portion 6 is folded so as to overlap with the stand support portion 5, the height of the tablet T can be lowered without changing the posture thereof (FIGS. 21 and 22). Such a posture of the tablet stand 200 is suitable, for example, when drawing with a touch pen or the like on the touch panel of the tablet T including the touch panel.

On the other hand, the user changes the angle between the stand portion 6 and the tablet support portion 7 and the angle between the stand portion 6 and the stand support portion 5 in the tablet stand 200 in the unfolded posture, thereby unfolding the posture of the tablet stand 200. It can be changed from the posture to the folding posture. That is, when the user wants to change the tablet stand 200 from the unfolded posture to the folded posture, the user performs the second operation S2 to allow both the first joint 8a and the second joint 8b to rotate. In this state, the tablet support section 7 and the stand support section 5 are rotated in the same direction (clockwise direction in FIG. 16) AR1 with respect to the stand section 6 . That is, the stand support portion 5 is rotated in the predetermined direction AR1 around the first joint 8a and brought closer to the stand portion 6, so that the stand support portion 5 partially overlaps one side of the stand portion 6. More specifically, the portion on one side of the stand portion 6 above the second joint 8b is housed in the concave portion 511 of the leg 51 . In addition, the tablet support portion 7 is rotated in the predetermined direction AR1 around the second joint 8b to be brought closer to the stand portion 6, and the tablet support portion 7 overlaps the other side of the stand portion 6. Practically, the platen plate 71 and the other side of the stand portion 6 are substantially entirely overlapped. As a result, the tablet stand 200 is in the folded posture (FIG. 23). In this folded posture, the stand portion 6 is sandwiched between the tablet support portion 7 and the stand support portion 5 . Needless to say, the procedure is reversed, that is, the tablet support portion 7 and the stand support portion 5 are rotated with respect to the stand portion 6 in the direction opposite to the predetermined direction AR1 (counterclockwise direction in FIG. 23) AR2. By moving, the tablet stand 200 in the folded posture can be changed to the unfolded posture.

The inner dimensions (width and length) of the recessed portion 511t are slightly larger than the outer dimensions (width and length) of the portion of the stand portion 6t above the first joint 8at. In a state in which the stand portion 6t connected to the leg 51t is rotated through the first joint 8at and both 51t and 6t are in a substantially parallel posture, the stand portion 6t is positioned above the first joint 8at. portion is accommodated in this concave portion 511t (FIGS. 34 and 35). At the upper end of the leg 51t, a protruding wall portion 512t is formed on each side wall portion of the leg 51t, and a through hole H51t is formed in each protruding wall portion 512t.

At the lower end of the leg 51t, a long concave support frame 513t is provided integrally with the leg 51t in such a posture that the long direction is along the width direction of the leg 51t. When using the tablet stand 200t, for example, the support frame 513t and the support portion are preferably placed against the flat installation surface G so that the lower edges of the support frame 513t and the support portion 64t, which will be described later, come into contact with the installation surface G. It is arranged so that the entire bottom edge of 64t is in contact.

A circular through hole 514t is formed in the middle of extension of the leg 51t, into which a penlight or the like can be inserted. In addition, the support frame 513t connected to the lower end of the leg 51t has a shape in which the frame portion 5131t on the lower end side of the support frame 513t is bent and protrudes. Sometimes, the lower end portion of the device is locked to this frame portion 5131t (Figs. 36 and 37). In other words, the frame portion 5131t constitutes a locking portion that locks the device leaned against the leg 51t. In this way, the through hole 514t and the frame portion (locking portion) 5131t both play a role as a lighting support portion that supports a penlight, a smart phone, or the like, which is a lighting device.

<1-2. Tablet support>
The tablet support portion 7t includes a mounting plate 71t and a holding member 72t.

The mounting plate 71t is a tablet receiving portion that receives the tablet T, and is a plate-like member that is rectangular in plan view. One main surface (upper surface) of the mounting plate 71t forms a mounting surface for mounting the tablet T thereon. A pair of projecting wall portions 712t, 712t are formed on the lower surface side near the lower end portion of the mounting plate 71, and a through hole H71t is formed in each projecting wall portion 712t. A cylindrical protrusion 713t is formed on the outer surface of each protrusion 712t so as to surround the through hole H71t. A holding member 72t is swingably attached to the cylindrical protrusion 713t.

The holding member 72t is a member for holding the tablet T placed on the upper surface of the placing plate 71t so as not to fall, and is attached to the cylindrical projection 713t so as to be swingable. located near the bottom end of the The holding member 72t includes a pair of swing support portions 721t, 721t, a tablet load receiving portion 722t, and two tablet pressers 723t, 723t.

The pair of swing support portions 721t, 721t are arranged in a substantially parallel posture with a predetermined gap therebetween. A circular concave portion 7211t is formed on the inner surface of the upper end portion of each swing support portion 721t. The diameter of the concave portion 7211t is larger than the outer diameter of the cylindrical projection 713t provided on the projecting wall portion 712t. Each concave portion 7211t of the pair of rocking support portions 721t, 721t is fitted onto each cylindrical protrusion 713t of the pair of projecting wall portions 712t, 712t. Thereby, the holding member 72t is swingably supported with respect to the pair of projecting wall portions 712t, 712t. Therefore, the cylindrical protrusion 713t serves as a rotation axis when the pair of swing support portions 721t, 721t swing.

The tablet load receiving portion 722t is a rectangular plate-shaped member having substantially the same width as the loading plate 71t, and is connected to the lower ends of the pair of rocking support portions 721t, 721t. The tablet load receiving portion 722 t is a portion that receives the load of the tablet T when the tablet T is attached to the tablet support portion 7 . As will be described later, after the tablet load receiving portion 722t is lifted against its own weight from a state in which no external force is acting on the tablet load receiving portion 722t, the tablet T is attached and the tablet load receiving portion 722t is lifted. When the load of the tablet T is received, the pair of rocking support portions 721t, 721t rock against the protruding wall portion 712t, and the tablet load receiving portion 722t rotates about the cylindrical protruding portion 713t as a rotating shaft.

The two tablet holders 723t, 723t have substantially the same width and are spaced apart in the width direction of the loading plate 71t. Each tablet presser 723t is a portion that presses the tablet T on the mounting plate 71t toward the rear, and extends upward from the tip of the tablet load receiving portion 722t. In addition, each tablet presser 723t is inclined such that the tip portion 7232t is arranged behind the base end portion 7231t. Each tablet presser 723t is integrally formed with the tablet load receiving portion 722t, and rotates together with the tablet load receiving portion 722t about the cylindrical protrusion 713t as a rotation axis. Therefore, when the tablet T is mounted, the tablet presser 723t is inclined such that the tip portion 7232t is closer to the tablet T than the base end portion 7231t, and presses the tablet T toward the mounting plate 71t. The pressing force of the tablet presser 723t changes according to the weight of the tablet T received by the tablet load receiving portion 722t. That is, the pressing force of the tablet presser 723t increases as the weight of the tablet T increases.

The tablet presser 723t is arranged in front of the placing plate 71t. A cylindrical protrusion 713t, which is the rotation axis of the pair of swing support portions 721t, 721t, is located rearward and upward of the tablet load receiving portion 722t, and the tablet presser 723t is movable together with the tablet load receiving portion 722t. Therefore, when the tablet load receiving portion 722 t receives the load of the tablet T and lowers, the tablet presser 723 t moves in the direction to bring the tablet T into close contact with the mounting plate 31 .

The support portion 64t is a rectangular frame-shaped member extending in the same direction as the main arm 61t, and its upper end side is fixed to the lower end portion of the main arm 61t. A restriction portion 641t is formed on the upper edge of the support portion 64t to restrict the angle formed between the portion of the stand portion 6t above the first joint 8t and the stand support portion 5t so as not to exceed a predetermined value. there is The support portion 64t functions as a support portion that supports the tablet stand 200t when the tablet stand 200t is in the unfolded posture, while the support portion 64t serves as a support portion for supporting the tablet stand 200t when the tablet stand 200t is in the folded posture. It serves as a handle for a person to hold and carry the tablet stand 200t. The support portion 64t and the main arm 61t are integrally formed, for example, by using an integral molding technique.

<1-4. First Joint, Second Joint>
The first joint 8at is formed like a clutch. That is, the first joint 8at has an engaging portion (first stand portion side engaging portion) 81at provided on the side of the stand portion 6t (specifically, the auxiliary arm 62t) and an engaging portion 81at on the side of the stand support portion 5t. provided engaging portion (first supporting portion side engaging portion) 82at. Both engaging portions 81at and 82at are rotatably supported by a shaft portion (first shaft portion) 80at, and the pair of engaging portions 81at and 82at are engaged/disengaged to form the first joint. A state in which the 8at rotation (that is, the rotation of the stand portion 6t with respect to the stand support portion 5t) is prohibited and a state in which the rotation is allowed are switched. Since the specific configuration and formation mode of the first joint 8at are substantially the same as those of the first joint 8a according to the second embodiment, detailed description thereof will be omitted. However, in the first joint 8at, the first supporting portion-side engaging portion 82at has a U-shaped convex portion 822t formed on the main surface opposite to the main surface on which the concave-convex structure is provided in the disk portion thereof. is accommodated in a recess 5121t corresponding to the projection 822t formed on the inner side surface of the projecting wall 512t, thereby being non-rotatably locked to the projecting wall 512t. . In addition, in the first joint 8at, after the screw 801at and the nut 802at are fastened, a cap 803at is put on the outer surface of the projecting wall portion 512t.

The second joint 8bt is formed like a clutch like the first joint 8at. That is, the second joint 8bt has an engaging portion (second stand side engaging portion) 81bt provided on the side of the stand portion 6t (specifically, the auxiliary arm 62t), and an engaging portion on the side of the tablet support portion 7t. provided engaging portion (second supporting portion side engaging portion) 82bt. Both engaging portions 81bt and 82bt are rotatably supported by a shaft portion (second shaft portion) 80bt. A state in which the 8bt rotation (that is, the rotation of the stand portion 6t with respect to the tablet support portion 7t) is prohibited and a state in which the rotation is permitted can be switched. The specific configuration and formation mode of the second joint 8bt are substantially the same as those of the second joint 8b according to the second embodiment, so detailed description thereof will be omitted. However, as in the first joint 8at, in the second joint 8bt as well, the second support side engaging portion 82bt is formed on the main surface opposite to the main surface on which the concave-convex structure of the disk portion is provided. The U-shaped convex portion 822t is arranged to be accommodated in a concave portion corresponding to the convex portion 822t formed on the inner side surface of the projecting wall portion 712t, thereby rotating with respect to the projecting wall portion 712t. Impossibly locked.

In the second joint 8bt, as in the second joint 8b according to the second embodiment, for example, the dimensions of each protruding wall portion 712t and the formation position of the through hole H71t provided therein are appropriately adjusted. As a result, a plane F including a tangent to the second joint 8bt, specifically a tangent to the disk portions of the second stand side engaging portion 81bt and the second support side engaging portion 82bt, is the plane of the mounting plate 71t. It is formed to approximately match the rear surface (Fig. 27). Furthermore, in the second joint 8bt, the dimension of each projecting wall portion 712t and the formation position of the through hole H71t provided here are appropriately adjusted, so that the second joint 8bt is within the thickness of the tablet support portion 7t. It is sized to fit in Specifically, the rear end edge (specifically, , the rear edge of the tablet load receiving portion 722t) and parallel to the loading plate 71t. dimensions (Fig. 27). Also, the first joint 8bt has approximately the same dimensions as the second joint 8bt.

<2. Manner of Operation>
The mode of operation of the tablet stand 200t is the same as the mode of operation of the tablet stand 200 according to the second embodiment. That is, in a state in which neither the first operation S1 nor the second operation S2 is performed, both the first joint 8at and the second joint 8bt are prohibited from rotating, and the stand portion 6t and the stand are supported. The portion 5t cannot rotate relative to each other, and the stand portion 6t and the tablet support portion 7t cannot rotate relative to each other. Further, when the user performs the first operation S1 on the tablet stand 200t in which the rotation of the first joint 8at and the second joint 8bt is prohibited, each of the first joint 8at and the second joint 8bt is individually switched from the prohibited state to the permitted state. Further, when the user performs the second operation S2, the rotation of both the first joint 8at and the second joint 8bt is switched from the prohibited state to the permitted state.

<3. Mode of use>
As described above, the tablet stand 200t is used, for example, by placing it on a flat installation surface G such as a desk in an office, home, or the like. to use. A mode of use of the tablet stand 200t will be described below.

<3-1. Wearing Tablet T>
A mode of mounting the tablet T on the tablet stand 100 will be described with reference to FIG. FIG. 31 is a diagram for explaining how the tablet T is attached to the tablet stand 100. FIG.

As described above, the holding member 72t is swingably supported by the cylindrical projection 713t provided on the projecting wall portion 712t. is moving toward the stand portion 2 with the cylindrical projection 713t as a rotation axis, and the tablet load receiving portion 722t is arranged substantially vertically below the cylindrical projection 713t, and the tip portion 7232t of the tablet holder 723t is placed thereon. It is in a state of being pressed against the lower end of the placing plate 71t (FIG. 31(a)).

From this state, when the tablet load receiving portion 722t is lifted against its own weight, the holding member 72t rotates about the cylindrical protrusion 713t as a rotation axis, and the tablet insertion opening is formed between the tablet holder 723t and the placing plate 71t. t opens. As the tablet load receiving portion 722t is lifted greatly, the rotation of the holding member 72t progresses and the tablet insertion opening t becomes larger. The holding member 72t is rotatable to a position where the pair of swing support portions 721t, 721t are in contact with the rear surface of the placing plate 71t. The opening t is sufficiently large with respect to the thickness of a general tablet T (Fig. 31(b)).

The user lifts the tablet load receiving portion 722t to open the tablet insertion opening t of an appropriate size, and inserts the tablet T through the opening. Then, with the lower end of the tablet T in contact with the tablet load receiving portion 722t, the hand is released from the tablet T (FIG. 31(c)). Then, the tablet load receiving portion 722t receives the load of the tablet T and lowers, so that the tip portion 7232t of the tablet presser 723t moves in the direction to bring the tablet T into close contact with the placing plate 71t. By mounting the tablet T in this manner, the contact portion between the tablet T and the tablet presser 723t approaches the placing plate 71t, and the tablet presser 723t brings the tablet T into close contact with the placing plate 71t (see FIG. 31 ( d)). Thereby, the tablet T placed on the placing plate 71t is supported so as not to fall.

<3-2. Posture change>
As described above, in the tablet stand 200t, the angle between the stand portion 6t and the stand support portion 5t and the angle between the stand portion 6t and the tablet support portion 7t can be changed by the user performing the operations S1 and S2 described above. Each of them can be changed independently, so that the posture and the like of the tablet stand 200t can be changed. A mode of changing the posture of the tablet stand 200t will be described with reference to FIGS. 32 to 35 in addition to FIGS. 24 and 25. FIG. 32 and 33 are diagrams showing the tablet stand 200t in the unfolded posture. 34 and 35 are diagrams showing the tablet stand 200t in the folded posture.

For example, the angle between the stand portion 6t and the stand support portion 5t and the angle between the stand portion 6t and the tablet support portion 7t are adjusted to be sufficiently small, so that the tablet stand 200t can be placed in the folded posture. (Figs. 34 and 35). Further, by adjusting the angle between the stand portion 6t and the stand support portion 5t and/or the angle between the stand portion 6t and the tablet support portion 7t from the folded posture, the tablet stand 200t can be changed from the folded posture to the unfolded posture. (Figs. 24, 25, 32, 33). Further, by changing each of these angles in the deployed posture, the height of the tablet support portion 7t (and thus the height of the tablet T supported by it) and the posture of the tablet support portion 7t (and thus this ) can be changed.

Specifically, for example, the user can change the posture of the tablet T supported by the tablet stand 200t by changing the angle between the stand portion 6t and the tablet support portion 7t in the tablet stand 200t in the unfolded posture. can. That is, when the user wants to change the posture of the tablet T, for example, the user performs the first operation S1 on the side of the second joint 8bt. Then, the second joint 8bt is allowed to rotate. In this state, by rotating the tablet support portion 7t around the second joint 8bt and appropriately adjusting the angle formed by the stand portion 6t and the tablet support portion 7t, the user can obtain the desired posture of the tablet T. can be of For example, the tablet T can be placed in a substantially vertical posture (solid line in FIG. 32), and from such a posture, the tablet support portion 7t can be rotated around the second joint 8bt so that the stand portion 6t and the tablet By changing the angle of the support portion 7t, the tablet T can be tilted backward (virtual line in FIG. 32). The former posture is suitable, for example, when the user wants to see the tablet T from the front, and the latter posture is suitable, for example, when the user wants to see the tablet T from diagonally above. Alternatively, the tablet T may be tilted forward.

Furthermore, the user can change the height of the tablet T supported by the tablet stand 200t by changing the angle between the stand portion 6t and the stand support portion 5t in the tablet stand 200t in the unfolded posture. That is, when the user wants to change the height of the tablet T, for example, the user performs the first operation S1 on the side of the first joint 8at. Then, the first joint 8at is allowed to rotate. In this state, the user can adjust the height of the tablet T as desired by rotating the stand portion 6t around the first joint 8at and appropriately adjusting the angle formed by the stand portion 6t and the stand support portion 5t. can be of

Moreover, when the user wants to change only the height of the tablet T without changing the posture of the tablet T, the user may perform the second operation S2. In this way, both the first joint 8at and the second joint 8bt are allowed to rotate. In this state, while rotating the stand part 6t around the first joint 8at, the tablet support part 7t is rotated around the second joint 8bt, and the angle formed by the stand part 6t and the stand support part 5t and the stand By appropriately adjusting each of the angles formed by the portion 6t and the tablet support portion 7t, the user can obtain a desired height without changing the posture of the tablet T (see the phantom line in FIG. 33). ).

On the other hand, the user changes the angle between the stand portion 6t and the tablet support portion 7t and the angle between the stand portion 6t and the stand support portion 5t in the tablet stand 200t in the unfolded posture, thereby expanding the posture of the tablet stand 200t. It can be changed from the posture to the folding posture. That is, when the user wants to change the tablet stand 200t from the unfolded posture to the folded posture, the user performs the second operation S2 to allow both the first joint 8at and the second joint 8bt to rotate. In this state, the tablet support portion 7t and the stand support portion 5t are rotated in the same direction (clockwise direction in FIG. 25) AR1 with respect to the stand portion 6t. That is, the stand support portion 5t is rotated in the predetermined direction AR1 around the first joint 8at and brought closer to the stand portion 6t so that the stand support portion 5t partially overlaps one side of the stand portion 6t. More specifically, the portion above the second joint 8bt on one side of the stand portion 6t is accommodated in the concave portion 511t of the leg 51t. In addition, the tablet support portion 7t is rotated in the predetermined direction AR1 around the second joint 8bt to bring it closer to the stand portion 6t so that the tablet support portion 7t partially overlaps the other side of the stand portion 6t. More specifically, the platen plate 71t and a portion of the other side of the stand portion 6t (that is, the frame portion of the upper end side of the support portion 64t and the portion above it) overlap each other. Further, the holding member 72t is brought into a state in which the tablet pressing portion 723t is in contact with the placing plate 71t and the tablet load receiving portion 722t is accommodated in the support frame 513t of the leg 51t. As a result, the tablet stand 200t is in the folded posture (FIGS. 34 and 35). In this folded posture, the stand portion 6t is sandwiched between the tablet support portion 7t and the stand support portion 5t. Needless to say, the procedure is reversed, that is, the tablet support portion 7t and the stand support portion 5t are rotated in the direction opposite to the predetermined direction AR1 (counterclockwise direction in FIG. 35) AR2 with respect to the stand portion 6t. By moving, the tablet stand 200t in the folded posture can be changed to the unfolded posture.

The folded posture is suitable when the tablet stand 200t is not used (during storage). As described above, in the tablet stand 200t, the plane F including the tangent line of the second joint 8at is formed so as to substantially match the rear surface of the mounting plate 71t (FIG. 27). The support portions 7 are arranged sufficiently close to each other, and the thickness of the tablet stand 200t is sufficiently small in the folded posture. Furthermore, as described above, the joints 8at and 8bt are sized to fit within the thickness of the tablet support portion 7t. , and the stand support portions 5t are arranged close to each other until they contact each other. Therefore, the thickness of the tablet stand 200t is particularly small in the folded posture. For this reason, it is difficult to take up space for storage.

In the folded posture, the portion of the stand portion 6t below the second joint 8bt, that is, the support portion 64t protrudes without overlapping the tablet support portion 7t and the stand support portion 5t. As described above, the support portion 64t has a rectangular frame shape and constitutes a handle that can be easily grasped by the user. Therefore, the user can easily carry the tablet stand 200t in the folded posture by holding the support portion 64t.

In addition, the second operation S2 is convenient for folding the tablet stand 200t (or unfolding the folded tablet stand 200t). That is, by performing the second operation S2, both the first joint 8at and the second joint 8bt are switched to a state in which rotation is permitted, and the parts 4, 5, and 6 are simultaneously rotated around the joints 8at and 8bt. As a result, the tablet stand 200t can be quickly folded (or unfolded).

<3-3. Lighting device>
A mode of use of the lighting support portion in the tablet stand 200t will be described with reference to FIGS. 36 and 37. FIG. FIG. 36 is a perspective view of the tablet stand 200t supporting a smartphone as a lighting device. FIG. 37 is a side view of the tablet stand 200t.

As described above, the stand support portion 5t is formed with the through hole 514t and the locking portion 5131t that function as the lighting support portion. When the smartphone L as a lighting device is placed against the leg 51t and the lower edge of the smartphone L is locked by the locking portion 5131t, the light of the smartphone L is turned on. It is configured such that the user facing the tablet T supported by 7t is illuminated from below. The same applies when a penlight or the like is inserted into the through hole 514t and the penlight is turned on. Therefore, for example, when the user uses the tablet T supported by the tablet stand 200t to make a video call or take a selfie, the user can illuminate from below the face to improve the camera image (so-called actress Wright).

<3-4. Drawing work>
The tablet stand 200t can also be suitably used when drawing with a touch pen or the like on the touch panel of the tablet T including the touch panel. A mode of such use will be described with reference to FIG. FIG. 38 is a perspective view of the tablet stand 200t in a state suitable for drawing work.

When the user wants to perform drawing work on the tablet T using the tablet stand 200, the user performs the first operation S1 or the second operation S2 to allow the rotation of the second joint 8bt. Then, the tablet support portion 7t is rotated around the second joint 8bt and brought closer to the stand portion 6t so that the tablet support portion 7t partially overlaps the stand portion 6t, more specifically, The platen plate 71t and a portion of the stand portion 6t (that is, the frame portion on the upper end side of the support portion 64t and the portion above it) overlap each other. Further, the first operation S1 or the second operation S2 is performed to allow the rotation of the first joint 8at, and in this state, the stand support portion 5t is rotated around the first joint 8at, This is a state in which the leg 51t abuts on the restricting portion 641t provided on the stand portion 6t by moving away from the portion of the stand portion 6t above the first joint 8t. As a result, the rotation posture of the leg 51t is restricted, and the leg 51t cannot rotate further away from the portion of the stand portion 6t. The tablet stand 200t is arranged such that the lower end of the tablet support portion 7t, specifically the lower end of the holding member 72t, and the lower end of the stand support portion 5t, specifically the support frame 513t, are in contact with the installation surface G. Place in posture.

When the tablet stand 200t is in such a posture, the tablet T is supported at a sufficiently low position and in a sufficiently inclined posture. Therefore, the user can draw with a touch pen or the like on the touch panel of the tablet T in a natural posture. In particular, in this posture, the leg 51t cannot rotate further away from the stand portion 6t, and the stand portion 6t and the tablet support portion 7t come into contact with each other, causing the entire tablet support portion 7t to move. It will be in the state supported by the stand part 6t from the back side. Therefore, even if a relatively strong pressing force is applied to the tablet T during drawing work, the posture of the tablet support portion 7t is unlikely to be changed. Such a posture of the tablet stand 200t is suitable not only for drawing work but also for various usage modes (for example, games) in which a relatively strong pressing force can be applied to the tablet T, and when it is desired to support the tablet T at a relatively low position. etc. is also suitable.

Needless to say, in the tablet stand 200t in the above posture, by rotating the stand support portion 5t around the first joint 8at and changing the angle formed by this and the stand portion 6t, the tablet can be It is possible to change the posture of the support portion 7t and, by extension, the tablet T supported by this.

<4. Effect>
According to the tablet stand 200t according to the above embodiment, the same effects as those of the tablet stands 100 and 200 according to the first and second embodiments can be obtained.

In addition, in the tablet stand 200t, the joints 8at and 8bt, which are the rotating shafts, are contained within the thickness of the tablet support portion 7t. According to this configuration, the joints 8at and 8bt, which are the rotating shafts, do not interfere with the folded posture, so the tablet stand 200t can be folded compactly.

In addition, in the tablet stand 200t, the supporting portion 64t that protrudes without overlapping the tablet supporting portion 7t of the stand portion 6t in the folded posture constitutes a carrying handle. Therefore, the user can easily carry the tablet stand 200t in the folded posture by holding the support portion 64t.

Further, in the tablet stand 200t, the stand support portion 5t is formed with a through hole 514t and a locking portion 5131t that function as a lighting support portion that supports the lighting device. In a state in which the illumination device is supported by the illumination support portion, illumination is applied from below the user facing the tablet T supported by the tablet support portion 7t. According to this configuration, for example, when the user makes a video call or takes a selfie, lighting can be applied from below the face to improve the camera image.

<<other embodiments>>
In the first embodiment, the height of the tablet support portion 3 is changed by relatively rotating the stand portion 2 and the stand support portion 1 around the first joint 4a. A change in height may be made in a manner other than this. For example, as in a tablet stand 100d shown in FIG. 39, a slide portion 123d is provided on the leg 12d of the stand support portion 1d, and the height of the tablet support portion 3 can be changed by sliding the slide portion 123d. may be used. In the illustrated example, the slide portion 123d includes two long members 1231d and 1232d, each of which has a U-shaped cross-section, and which are arranged in a nested manner and are connected in a telescopic manner so as to be slidable in the axial direction. It is realized by having a structure that expands and contracts in a formula. In this configuration, the leg 12d expands and contracts by sliding the long members 1231d and 1232d relative to the other, thereby changing the height of the tablet support section 3. As shown in FIG. Note that the slide portion 123 d may be provided on the stand portion 2 . Moreover, when providing the slide part 123d, you may abbreviate|omit the 1st joint 4a. Similarly, in the second and third embodiments, the height change of the tablet support portions 7, 7t is realized by the sliding operation of the slide portions provided on the stand portions 6, 6t or the stand support portions 5, 5t. good too.

Moreover, although the mounting plate 31 is made of a transparent material in the first embodiment, it may be made of a non-transparent material. When formed of a non-transparent material, it is preferable that the placement plate 31 has a window formed at a position corresponding to the camera lens of the tablet T placed thereon. Moreover, in the second and third embodiments, the mounting plates 71 and 71t may be made of a transparent material.

Further, in the first embodiment, instead of the coil spring 23, various elastic members (for example, plate springs) may be employed. In order to improve the strength of each joint 4a, 4b, a torsion coil spring or a compression coil spring may be appropriately added to each joint 4a, 4b. The same applies to the second and third embodiments.

In addition, in the first embodiment, the screen of the tablet T is exemplified to be placed on the placing plate 31 with the screen facing upward, but the usage mode of the tablet stand 100 is not limited to this. For example, the mounting plate 31 may be made of a transparent material, the screen of the tablet T may be placed on the mounting plate 31 with the screen facing downward, and the screen may be viewed through the transparent mounting plate 31 . The same applies to the second and third embodiments.

Moreover, in the first embodiment, the tablet T supported by the tablet stand 100 may be of any size. It is also preferable to appropriately adjust the size and the like of the placing plate 31 according to the size of the tablet T that is assumed to be used. The same applies to the second and third embodiments.

Moreover, the structure which supports the stand part 2 which concerns on 1st Embodiment so that rotation is possible with respect to each support part 1 and 3 is not restricted to what was demonstrated above. For example, the stand portion 2 is rotatably supported by housing the projections provided on the stand portion 2 in the recesses provided on the projecting wall portions 122 and 312 of the support portions 1 and 3. There may be. The same applies to the second and third embodiments.

In addition, in the second embodiment, narrowed portions (a pair of contact projections 622, 622) that narrow the distance between the main arm 61 and the auxiliary arm 62 are formed on the inner surface of the auxiliary arm 62. The protrusion may be formed on the inner surface of the main arm 61 . Also in this case, the pair of contact protrusions are formed while providing a space in the extending direction of the stand portion 6, and are formed so that their intermediate positions coincide with the intermediate positions of the first joint 8a and the second joint 8b. be. Moreover, each contact convex portion is preferably formed at a position corresponding to the boundary between the central flat portion 6212 of the operation receiving portion 621 and each operation convex portion 6211 or in the vicinity thereof. The same applies to the first and third embodiments.

Further, in the second embodiment, the constricted portion is formed by the pair of contact protrusions 622, 622, but the form of the constricted portion is not limited to this. For example, the constricted portion may be formed by a long ridge along the extending direction of the stand portion 6 . In this case, the central position of the ridge in the longitudinal direction coincides with the intermediate position between the first joint 8a and the second joint 8b, and the end in the longitudinal direction is the central flat portion of the operation receiving portion 621. It is preferably formed at a position corresponding to the boundary between 6212 and each operation convex portion 6211 or in the vicinity thereof. Also, the protruding portion has a flat top surface. Also in this case, for example, when the vicinity of the first stand side engaging portion 81a or the second stand side engaging portion 81b of the auxiliary arm 62 is pressed against the urging force of the coil spring 63, the protruded portion is When the auxiliary arm 62 and the main arm 61 abut through one end, the auxiliary arm 62 cannot rotate any more and can slide entirely in a direction approaching the main arm 61. As a result, it is possible to reliably avoid disengagement of the engaging portions 81a and 82a on the non-pressed side. Therefore, the rotation of only one joint is reliably permitted in the first operation S1. The same applies to the first and third embodiments.

In addition, in the third embodiment, the supporting portion 64t that constitutes the handle for carrying is assumed to have a rectangular frame shape, but the configuration of the supporting portion 64t is not limited to this, and may be Y-shaped, T-shaped, or the like. etc.

Further, in the third embodiment, the surface of the placing plate 71t may be provided with an uneven structure for suppressing the slippage of the tablet T placed thereon. Specifically, for example, a plurality of ridges extending in parallel may be provided on the surface of the mounting plate 71t. The same applies to the mounting plates 31 and 71 of the first and second embodiments.
