  Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a perspective view illustrating an example of a bottom portion of the display device according to the embodiment. The display device 1 is a monitor that displays information, for example, a liquid crystal display in a palm vein authentication device, but is not limited to a liquid crystal display. The display device 1 is provided with an angle (inclination) in order to improve the visibility of the display (display screen) and the operability when the hand is held over the display, that is, the angle can be adjusted.

  For example, when the display device 1 is installed in a store or the like and visibility is poor due to the influence of lighting or external light in the store, the angle can be adjusted to improve the visibility of the display. In the case where the display device 1 holds the palm of the hand over the display like a palm vein authentication device, the height varies depending on the user holding the hand. Therefore, it is possible to improve the operability by adjusting the angle according to the height. .

  The angle adjustment can be performed using a stand 11, a stand storage section (hereinafter simply referred to as a storage section) 12, a hole 13, and a slit 14, which will be described later, and these are provided on the bottom section 10 of the display device 1. (See FIG. 1). The bottom portion 10 is attached to the main body of the display device 1 by a structure that can be detached from the bottom surface of the display device 1, for example, a structure in which a convex portion provided on the main body side of the display device 1 and a concave portion provided on the bottom portion 10 side are fitted. Be combined. The structure for coupling is not limited to this, and may be coupled by another structure. The display device 1 can be connected to a wiring group 16 for supplying power to the display device 1 and transmitting information as shown in FIG.

  As shown in FIGS. 1 to 5, a stand 11 (11 a, 11 b), a storage part 12 (12 a, 12 b) for storing the stand 11, and a hole 13 (13 a) for fitting the stand 11 are provided in the bottom part 10. , 13b, 13c, 13d) and slits 14 (14a, 14b, 14c, 14d) connecting the plurality of holes 13 are provided.

  Each of the holes 13 is provided with a pair of holes facing each other in the storage unit 12, and a protrusion 20 of the stand 11, which will be described later, is fitted into each of the pairs of holes 13. Similarly, the slit 14 is provided with a pair of slits facing each other in the storage unit 12, and is used as a passage when the stand 11 moves between the holes 13 as described later.

  The stand 11 attaches to the bottom surface 10 and exposes it from the storage unit 12 to give an angle to the display surface of the display device 1. As an angle setting method, the stand 11 is rotated after being fitted into the hole 13, and the stand 11 is pressed against (contacted with) the wall surface 15 (15a, 15b) of the storage section 12 shown in FIG. The stand 11 is fixed and angled by placing the display device 1 on the like. Here, the wall surface 15 is a wall surface of the storage unit 12 that comes into contact when the stand 11 is rotated.

  As shown in FIG. 2, the stand 11 has protrusions 20 (20a, 20b) formed symmetrically with respect to the longitudinal direction of the stand 11. The stand 11 is attached by fitting the projection 20 into the hole 13. That is, the protrusions 20 are formed symmetrically with respect to the longitudinal direction of the stand 11, and each of the protrusions 20 is fitted into the corresponding hole 13 in the storage unit 12. For example, the stand 11 is mounted in the storage unit 12 by fitting the protrusion 20a into the hole 13a and fitting the hole 20b into a pair of holes 13b facing the hole 13a.

  Here, when the stand 11 is attached, two projections 20 (for example, 20a and 20b) and two holes 13 (for example, 13a and 13b) are used, but one projection 20 corresponding to one projection 20 is used. The mounting may be performed using only the three holes 13.

  Further, when the stand 11 is fitted into the hole 13, a notch 21 (21 a, 21 b) may be provided in a part of the stand 11 so as to be easily fitted. As a result, the stand 11 expands and contracts in the lateral direction. Therefore, at the time of fitting, one of the projections 20 (for example, 20a) is fitted into the hole 13 (for example, 13a), and in that state, a force is applied in the lateral direction of the stand 11 to expand and contract, and the other projection 20 (for example, , 20b) into the holes 13 (for example, 13b) that form a pair with the holes 13a. Thereby, the stand 11 can be easily fitted into the hole 13. In this case, the stand 11 is preferably made of a stretchable material, for example, a material such as plastic, but is not limited to this.

  Further, cutouts 22 (22a, 22b) are formed on the protrusions 20 of the stand 11 as shown in FIG. The notch 22 is formed by flattening a part of the cylindrical portion of the projection 20. That is, the projection 20 is processed according to the width 31 of the slit 14. Here, as shown in FIG. 3, the width 31 of the slit 14 (14a) is configured to be smaller than the length 30 of the diameter of the circle of the hole 13 (13a).

  There is a reason to adopt such a configuration. As shown in FIG. 5, the stand 11 (11a, 11b) is unfolded (exposed) from the storage section 12 (12a, 12b), and the stand 11 is pressed against a wall surface 15 of the storage section 12, which will be described later. When the display device 1 is placed on the display surface, an angle is given to the display surface. In this state (deployed state), a force may be applied from the upper part of the display device 1. However, even if the force is applied, the projection 20 is not moved to another hole 13 through the slit 14. The width 31 of the slit 14 is smaller than the length 30 of the diameter of the circle of the hole 13. This makes it difficult for the projection 20 to move to another hole 13 even when a force is applied, and the angle set during operation can be maintained.

  On the other hand, as will be described later, when adjusting the angle, the projection 20 of the stand 11 is fitted into another hole 13 so that it is necessary to easily move between the holes 13. Therefore, the notch 22 is provided in a part of the protrusion 20 so that the notch protrusion 20 can pass through without being caught by the slit 14. In order to smoothly pass through the slit 14, the notch is formed so that the length 23 from the end of the notched flat surface to the opposite circular end is equal to or shorter than the width 31 of the slit 14 (see FIG. 2). ). Although only one flat surface is cut out here, a flat surface may be provided on the side opposite to the flat surface, and two flat surfaces may be provided.

  As shown in FIG. 1, the storage section 12 is a space for storing the stand 11, and a part of the bottom section 10 is hollowed out. The space of the storage section 12 is covered with four wall surfaces. In this example, the storage unit 12 is a space having a rectangular parallelepiped (or cubic) shape, but is not limited to this, and may be a space having another shape such as a cylindrical shape.

  The storage unit 12 is provided with a hole 13 and a slit 14. For example, the storage unit 12a is provided with holes 13a and 13b and slits 14a and 14b. The hole 13a and the hole 13b, and the slit 14a and the slit 14b are opposed to each other in the storage unit 12, and each is a pair.

  When the stand 11 (11a, 11b) is stored in the storage unit 12, the state is as shown in FIG. 4, and the stand 11 (11a, 11b) is extended (exposed) from the storage unit 12. In this case, the state is as shown in FIG.

  When the stand 11 is stored in the storage unit 12, the display surface is not angled, and the display surface is flat with respect to the desk surface on which the display device 1 is placed. On the other hand, when the display device 1 is placed on a desk in a state where the stand 11 is unfolded from the storage unit 12 and the stand 11 is pressed against the wall surface 15 (15a, 15b) of the storage unit 12, the display surface is angled. (See FIG. 5).

  The hole 13 is for fitting the protrusion 20 of the stand 11 to attach the stand 11 to the bottom surface 10, and makes the stand 11 rotatable. The holes 13 have opposing holes that form a pair in the storage unit 12. For example, in FIG. 1, the holes 13a and 13b and the holes 13c and 13d are a pair of holes, respectively.

  The number of the holes 13 is not limited to this, and there may be more holes. Since the holes 13 are aligned on a straight line in the horizontal direction, the rotation range of the stand 11 increases as the holes 13 move away from the predetermined wall surface 15 of the storage unit 12, and the angle formed by the stand 11 decreases. . Therefore, the inclination of the display surface of the display device 1 becomes gentler as the hole 13 moves away from the wall surface 15. That is, the angle is determined and adjusted by the distance between each hole and the wall surface 15 of the storage unit 12.

  The slits 14 are provided between the holes 13 and serve as passages for moving the stand 11 to other holes 13. Like the hole 13, the slit 14 has a pair of opposed slits in the storage section 12, respectively. For example, in FIG. 1, the slits 14a and 14b and the slits 14c and 14d are a pair of slits. Since the slit 14 is a passage connecting the holes 13, the number of the slits 14 increases as the number of the holes 13 increases.

  The width 31 of the slit 14 is smaller than the length 30 of the diameter of the circle of the hole 13. This is because the display device 1 is placed on a desk or the like in a state where the stand 11 is fitted into the hole 13 and the angle is set, and when a force is applied from the upper portion of the display device 1, the projection 20 of the stand 11 This is for preventing the hole 13 from moving. Even if the width 31 of the slit 14 is smaller than the length 30 of the diameter of the circle of the hole 13, a projection is provided so that the stand 11 can be easily moved to another hole 13 for adjusting the angle. A cutout portion 22 is provided in the portion 20. Thus, the projection 20 does not move to another hole 13 when the stand 11 is fixed, and the projection 20 can be easily moved to another hole 13 during angle adjustment.

  Next, a specific example of the angle adjustment structure of the display device according to the embodiment will be described. First, a state where the tilt angle of the display device 1 is 0 degrees will be described with reference to FIGS. 6A to 6C. FIG. 6A is a side view of the display device 1 in a state where the inclination angle of the display device 1 is 0 degree. As shown in FIG. 6A, since the inclination angle of the display device 1 is 0 degrees, the display device 1 is placed horizontally with respect to the installation surface 60 of the desk. FIG. 6B is an enlarged view of a region including the hole 13 into which the stand 11 which is a part of the rear surface (the surface to which the wiring group 16 is connected) is fitted.

  When the inclination angle of the display device 1 is 0 degrees, the stand 11 is housed in the housing 12 in a state of being fitted into the hole 13. That is, the stand 11 is not exposed. At this time, the flat surface of the notch 22 of the projection 20 of the stand 11 is not parallel to the moving direction 61 in the slit 14. This makes it difficult for the protrusion 20 of the stand 11 to move to another hole 13 via the slit 14.

  FIG. 6C is a cross-sectional view of the stand 11 stored in the storage unit 11 at this time. As shown in FIG. 6C, the stand 11 is housed in the housing 12 in a manner not to be exposed.

  Next, a state in which the inclination angle of the display device 1 is 5 degrees will be described with reference to FIGS. 7A to 7C. FIG. 7A is a side view of the display device 1 in a state where the inclination angle of the display device 1 is 5 degrees. As shown in FIG. 7A, since the display device 1 has an inclination angle of 5 degrees, the display device 1 is inclined 5 degrees with respect to the desk installation surface 60. FIG. 7B shows an enlarged view of a region including the hole 13 into which the stand 11 as a part of the back surface is fitted at this time.

  When the inclination angle of the display device 1 is 5 degrees, when the inclination angle is 0 degrees, the projection 20 is fitted into the hole 13 different from the hole 13 into which the projection 20 of the stand 11 was fitted. I have. This is done by rotating the stored stand 11 and unfolding it from the storage part 12, making the flat surface of the notch 22 of the projection 20 parallel to the movement direction 61 in the slit 14 and passing through the slit 14. The projection 20 is moved to another hole 13 and is fitted.

  At this time, the flat surface of the notch 22 of the projection 20 of the stand 11 is not parallel to the moving direction 61 in the slit 14. This makes it difficult for the protrusion 20 of the stand 11 to move to another hole 13 via the slit 14 even when a force is applied from the upper portion of the display device 1 or the like.

  FIG. 7C is a cross-sectional view of the stand 11 at this time. As shown in FIG. 7C, the stand 11 is fixed when it is placed on the installation surface 60 of the desk by being pressed (contacted) against the wall surface 15 of the storage unit 12, and is tilted (5 degrees) to the display device 1. Is attached.

  Next, a state where the tilt angle of the display device 1 is 10 degrees will be described with reference to FIGS. 8A to 8C. FIG. 8A is a side view of the display device 1 in a state where the inclination angle of the display device 1 is 10 degrees. As shown in FIG. 8A, since the display device 1 has an inclination angle of 10 degrees, the display device 1 is inclined 10 degrees with respect to the installation surface 60 of the desk. FIG. 8B shows an enlarged view of a region including the hole 13 into which the stand 11 as a part of the back surface is fitted at this time.

  When the inclination angle of the display device 1 is 10 degrees, and when the inclination angle is 5 degrees, the projection 20 is fitted into the hole 13 different from the hole 13 into which the projection 20 of the stand 11 was fitted. I have. When changing the inclination angle from 5 degrees to 10 degrees, the stand 11 is rotated, and the flat surface of the cutout portion 22 of the projection 20 is made parallel to the moving direction 61 of the slit 14 to pass through the slit 14. Then, the protrusion 20 is moved to another hole 13 and fitted. The fitted hole 13 is the same as the hole 13 to which the projection 20 was fitted when the inclination angle was 0 degree. However, the orientation of the flat surface of the notch 22 of the projection 20 differs from the orientation of the notch 22 fitted in the hole 13 at each inclination angle. This is because the stand 11 is turned to make an angle.

  At this time, the flat surface of the notch 22 of the projection 20 of the stand 11 is not parallel to the moving direction 61 in the slit 14. This makes it difficult for the protrusion 20 of the stand 11 to move to another hole 13 via the slit 14 even when a force is applied from the upper portion of the display device 1 or the like.

  FIG. 8C is a sectional view of the stand 11 at this time. As shown in FIG. 8C, the stand 11 is fixed when it is placed on the installation surface 60 of the desk by being pressed (contacted) against the wall surface 15 of the storage unit 12, and the display device 1 has an inclination angle (10 degrees). Is attached.

  Next, details of the movement of the slit 14 of the projection 20 of the stand 11 will be described. FIG. 9A is a diagram illustrating the back surface of the display device 1 when the protrusion 20 of the stand 11 moves the slit. When the projection 20 moves in the slit, the display device 1 is lifted and the stand 11 is rotated, so that the flat surface of the notch 22 of the projection 20 is parallel to the movement direction 61 in the slit 14. FIG. 9B is an enlarged view of the stand 11 when the slit is moved, and FIG. 9C is a perspective view thereof.

  As shown in FIGS. 9B and 9C, a state in which the stand 11 is rotated such that the flat surface of the notch 22 is parallel to the moving direction 61 in the slit 14 is shown. Accordingly, the slit 20 can be easily moved without the protrusion 20 being caught by the slit 14, and the structure becomes strong when the stand 11 is deployed (fixed).

  Next, the display device 1 when the inclination angle is set to four stages will be described. FIG. 10A is a diagram illustrating the back surface of the display device 1 when the inclination angle is the second smallest after 0 degree among the four stages. The four inclination angles are, for example, angles of 0 degree, 3 degrees, 5 degrees, 10 degrees, and the like. In order to provide these four degrees of inclination angles, three holes 13 and respective holes 13 are formed. Two connecting slits 14 are required. An enlarged view of the stand 11 (11a) at this time is shown in FIG. 10B, and a cross-sectional view is shown in FIG. 10C.

  As shown in FIG. 10B, there are three holes 13 into which the protrusions 20 of the stand 11a can be fitted, and the protrusions 20 are fitted into the holes 13i, and as shown in FIG. By being pressed against the wall surface 15, a tilt angle (for example, 3 degrees) next to 0 degree among the four steps is formed. When a further inclination angle (for example, 5 degrees) is provided, the protrusion 20 is moved on the slit 14 to be fitted into the central hole 13k, and when a further inclination angle (for example, 10 degrees) is provided. The part 20 is moved on the slit 14 and fitted into the hole 13m on the right end.

  FIG. 10D is a perspective view from the bottom side of the display device 1 when the inclination angle is the second smallest angle of 0 degree among the four stages of the stand 11 (11a, 11b). When the display device 1 is placed on a desk or the like in this state, the display device 1 can have the minimum inclination angle. As described above, by increasing the number of the holes 13, the inclination angle can be provided in multiple stages.

  Next, adjustment of the inclination angle by adjusting the length of the legs of the stand 11 and the distance between the holes 13 will be described.

  First, adjustment of the inclination angle by adjusting the length of the legs of the stand 11 will be described. FIG. 11A is a rear view of the display device 1 when the inclination angle is 15 degrees. The stand 11 (11a, 11b) here is longer than the legs of the above-described stand 11 (11a, 11b). Although the number of the holes 13 is only two here, the angle can be finely adjusted by increasing the number of the holes 13 and the number of the slits 14 as described above.

  FIG. 11B is an enlarged view of the stand 11a when the inclination angle is 15 degrees, and FIG. 11C is a cross-sectional view of the stand 11a. By increasing the length of the legs of the stand 11 (11a), the projections 20 are fitted into the same holes 13 so that the stand 11 (11a) has a more inclined angle than the stand with the shorter legs pressed against the wall surface 15 of the storage unit 12. Becomes possible. FIG. 11D is a perspective view of the display device 1 in this case as viewed from the bottom surface side. When the display device 1 is placed on a desk or the like in this state, the display device 1 can have an inclination angle of 15 degrees. Note that the legs of the stand 11 can be made extendable and contractible. This enables finer adjustment of the tilt angle.

  Next, adjustment of the inclination angle by adjusting the distance between the holes 13 will be described. FIG. 12A is a rear view of the display device 1 when the distance between the holes 13 is increased. The distance between the holes 13 (between the holes 13a and 13e) is longer than the distance between the holes 13 (between the holes 13a and 13e) in FIG. Increasing the distance between the holes 13 increases the range of rotation until the stand 11 is pressed against the wall surface 15 of the storage unit 12, so that the inclination angle can be adjusted to be smaller. That is, the angle is determined by the distance between the holes 13.

  For example, as shown in FIG. 12B, consider a state in which the protrusion 22 of the stand 11 is fitted into the hole 13g and the stand 11 is stored in the storage unit 12. From this state, the stand 11 is rotated and unfolded from the storage portion 12, and the flat surface of the cutout portion 22 of the protrusion 20 is made parallel to the movement direction 61 in the slit 14, and the protrusion 20 is moved to another hole 13c.

  After the movement, when the stand 11 is further rotated and pressed against the wall surface 15 of the storage unit 12, the distance between the hole 13c after the movement and the hole 13g is large, that is, since the distance between the hole 13c and the wall 15 is large. Rotates more, and the angle between the bottom surface of the display device 1 and the desk installation surface 60 becomes smaller. Thus, the inclination angle can be adjusted by adjusting the distance between the holes 13.

  According to the above-described display device, the tilt angle of the display surface can be adjusted in a limited space. Further, the number of components for forming an angle can be reduced, and the cost can be reduced. In addition, the slit can be easily moved by the cutout portion of the stand, and a structure in which the protrusion is difficult to move to another hole at the time of installation (at the time of fixing) can be provided.

  Further, the above-described embodiment is not limited to the above-described embodiment, and various changes can be made without departing from the spirit of the embodiment.
