  The information processing device 1 according to the present embodiment is a wireless device, more specifically, an access point. Referring to FIG. 1, the information processing device 1 includes an antenna 10 mounted on the information processing device main body 2 via a screw member 13. The information processing apparatus main body 2 includes a substantially rectangular housing main body 3. On the upper part of the housing main body 3, a lid 4 is detachably provided. The housing of the information processing apparatus main body 2 is formed by attaching the lid 4 to the housing main body 3. In the present embodiment, antennas 10 are provided at the four corners of the information processing apparatus main body 2 having a substantially rectangular shape. However, the number and locations of the antennas 10 are not limited thereto. The antenna 10 can be rotated and bent. This will be described in detail later.

  The information processing device main body 2 includes an antenna housing 5 on each of a pair of opposing side surfaces of the four sides of the rectangle. The antenna housing 5 is formed as a region surrounded by the bottom 5a, the side wall 5b, and the partition 5c. The antenna 10 is rotated in a desired direction and is folded and stored in the antenna housing 5. The partition wall 5c is a wall separating the inside and the outside of the information processing apparatus main body 2, and has an antenna mounting hole 5c1 formed at a position where the antenna 10 is mounted. The cylindrical sliding member 20 mounted on the end of the antenna 10 is exposed in the antenna mounting hole 5c1.

  Each side wall portion 5b is located at a corner of the information processing device main body 2, and projects in a flange shape. Such a side wall portion 5b also has a function of protecting the antenna 10.

  Referring to FIG. 2, the housing main body 3 includes a bottom plate 3a, a first side wall 3b, a second side wall 3c, a third side wall 3d, and a fourth side wall 3e, and is surrounded by these. A substrate storage recess 3f is formed. In the housing body 3, the first side wall 3b and the second side wall 3c face each other, and the third side wall 3d and the fourth side wall 3e face each other. Each of the third side wall 3d and the fourth side wall 3e becomes a part of the partition wall 5c. Further, a main body side cutout portion 5c11 which is a part of the antenna mounting hole 5c1 is provided.

  The chassis 6 on which the substrate is installed is provided in the substrate storage recess 3f. Note that the substrate is omitted in FIG. 2 for convenience of explanation. A bracket 7 is provided on the chassis 6 so as to correspond to the position of the main body side cutout 5c11. An antenna terminal 8 is attached to each bracket 7. The antenna terminal 8 includes a thread portion 8a located above the main body side cutout portion 5c11. The thread portion 8a corresponds to a first thread portion.

  Referring to FIG. 3, the cover 4 includes a side wall 4a. When the lid portion 4 is covered by the housing main body portion 3, the side wall portion 4 a is brought into a state of abutting against the third side wall portion 3 d (or the fourth side wall portion 3 e) provided in the housing main body portion 3, The partition 5c is formed. The side wall 4a is provided with a lid-side cutout 5c12. The lid side cutout 5c12 forms a circular antenna mounting hole 5c1 by being combined with the main body side cutout 5c11. The rotation stopper 9 is provided in the lid side notch 5c12. The rotation stopper 9 is provided as a plurality of engagement teeth each having a contact surface 9a. An external tooth portion 20b of the sliding member 20, which will be described in detail later, contacts the contact surface 9a, thereby preventing the sliding member 20 from rotating.

  Referring to FIG. 4, the rotation stopper 9 is provided only on the side wall 4 a of the lid 4, but may be provided on the housing body 3 side, or the housing body 3 and the lid 4 may be provided. You may provide in both.

  The rotation stopping portion 9 of the present embodiment is provided as engaging teeth of right-angled triangles that are continuous in the circumferential direction, and has a contact surface 9a that is perpendicular to the arc of each right-angled triangle. The contact surface 9a in the present embodiment extends perpendicular to the arc of the antenna mounting hole 5c1. That is, if the contact surface 9a is extended toward the center of the antenna mounting hole 5c1, it passes through the center point of the antenna mounting hole 5c1. By providing the contact surface 9a in this way, it is possible to suppress the slippage at the time of engagement between the contact surface 9a and the external tooth portion 20b, and to reliably engage the contact surface 9a with the external tooth portion 20b. it can. Specifically, the contact surface 9a comes into contact with the external tooth portion 20b when the sliding member 20 tries to turn in the loosening direction, that is, in the counterclockwise direction.

  In the present embodiment, the shape of the engagement teeth provided with such a contact surface 9a is a right triangle, but the shape is not limited to this, and may be, for example, rectangular engagement teeth. The form of the rotation stopper 9 is not limited as long as the external teeth 20b of the sliding member 20 are in contact with the rotation stopper 9 so that the rotation of the sliding member 20 is prevented.

  Next, the antenna 10 will be described. The antenna 10 includes an antenna body 11, a connection member 12, and a screw member 13, and an antenna wire 14 is provided inside. The connection member 12 is attached to the antenna main body 11 via a pin member 12a. Thereby, the antenna main body 11 bends with the pin member 12a as a fulcrum. Referring to FIGS. 10A and 10B, the connection member 12 has a hollow inside, and a sliding groove 12b is provided on the inner peripheral wall surface along the circumferential direction. The sliding projection 13c of the screw member 13 is inserted into the cavity, and the sliding projection 13c fits in the sliding groove 12b. 11 can be rotated.

  The screw member 13 is a cylindrical member, and has a vertical groove 13a provided on the outer peripheral surface along the axial direction AX. The vertical groove portion 13a in the present embodiment is formed by providing isosceles triangular engaging teeth continuously in the circumferential direction. The shape of the engaging teeth forming the vertical groove portion 13a is not limited to an isosceles triangle, and may be another shape. For example, the shape of the engagement teeth may be rectangular.

  The screw member 13 also has a thread portion 13b on its inner peripheral surface. The thread portion 13b corresponds to a second thread portion, and is screwed with a thread portion 8a of the antenna terminal 8. The antenna 10 can be attached to the antenna terminal 8 by narrowing the screw member 13 to the thread portion 8a. By performing the reverse operation, the antenna 10 can be removed from the antenna terminal 8.

  When such a screw member 13 is in a state of being narrowed down, as shown in FIG. 7, the screw member 13 is in a state of overlapping with the cutout portion 5c11 on the main body side. In order to properly mount the antenna 10, it is necessary to securely screw the thread portion 13 b of the screw member 13 with the thread portion 8 a of the antenna terminal 8. However, the screw member 13 is in a state of overlapping with the main body-side cutout 5c11. In other words, the screw member 13 enters into the antenna mounting hole 5c1. For this reason, the operation of pinching and rotating the screw member 13 to narrow or loosen the thread portion 8a of the antenna terminal 8 becomes difficult. Particularly, in the present embodiment, the operation of the screw member 13 is made more difficult because the side wall portion 5b exists near the antenna mounting hole 5c1.

  Therefore, in the present embodiment, the sliding member 20 is mounted on the screw member 13 as shown in FIG. Referring to FIGS. 8 and 9, the sliding member 20 is a cylindrical member, and has an inner tooth portion 20 a on its inner peripheral surface that meshes with the vertical groove portion 13 a provided in the screw member 13. Further, the sliding member 20 includes an external tooth portion 20b provided on the outer peripheral surface thereof so as to be engageable with the rotation stopping portion 9 provided in the information processing apparatus main body 2.

  The shape of the internal teeth portion 20a may be any shape as long as it can mesh with the longitudinal groove portion 13a in the circumferential direction, and in the present embodiment, is an isosceles triangle. The sliding member 20 can slide with respect to the screw member 13 along the axial direction AX thereof and can rotate together with the screw member 13 when the internal teeth portion 20a meshes with the longitudinal groove portion 13a in the circumferential direction.

  The shape of the external tooth portion 20b is a right-angled triangle that can engage with the rotation stopping portion 9. Referring to FIG. 9, the external tooth portion 20b includes a guide tooth portion 20b1 provided on the distal end side and a fixed tooth portion 20b2 continuous with the guide tooth portion 20b1.

  The sliding member 20 slides on the screw member 13 between a first position shown in FIGS. 10A and 11 and a second position shown in FIGS. 10B and 12. That is, the sliding member 20 can move along the axial direction AX. The first position is a position at which the engagement between the external teeth portion 20b and the rotation stopper 9 is released. The second position is a position where the external teeth portion 20b and the rotation stopper 9 are engaged.

  When the sliding member 20 is at the first position, the external teeth portion 20b is disengaged from the rotation stopper 9 and is in a rotatable state. The sliding member 20 is located outside the antenna mounting hole 5c1, and is in a state where the operator can easily pinch it. Thus, by gripping and rotating the sliding member 20, the screw member 13 meshing with the sliding member 20 can be appropriately narrowed. Further, when the antenna 10 is to be removed, the screw member 13 can be easily loosened and the antenna 10 can be removed by pulling out the sliding member 20 to the first position.

  On the other hand, when the sliding member 20 is at the second position, the rotation of the sliding member 20 is restricted, and thus the rotation of the screw member 13 is restricted, so that the loosening of the screw member 13 is prevented.

  The fixed tooth portion 20b2 extends along the sliding direction of the sliding member 20. That is, the fixed tooth portion 20b2 extends along the axial direction AX of the screw member 13. When the fixed tooth portion 20b2 is at the second position, the fixed tooth portion 20b2 comes into contact with the contact surface 9a of the rotation stopper 9 and is engaged with the rotation stopper 9. On the other hand, the guide tooth portion 20b1 extends so as to be inclined with respect to the sliding direction of the sliding member 20, that is, the axial direction AX. When the sliding member 20 shifts from the first position to the second position, the guide tooth portion 20b1 provided so as to be inclined may collide with the engagement tooth of the rotation stopping portion 9, It can rotate appropriately while moving along the axial direction AX. Thereby, when the sliding member 20 moves to the second position, the fixed tooth portion 20b2 is guided to be engaged with the rotation stopping portion 9, and finally the fixed tooth portion 20b2 is brought into contact with the contact surface 9a. Make contact. The shape of the external teeth portion 20b in the present embodiment is a right-angled triangle corresponding to the shape of the rotation stopper 9, but can be appropriately changed according to the shape of the rotation stopper 9.

  A claw portion 20 c is provided at the tip of the sliding member 20. The claw portion 20c engages with the tip of the screw member 13 when the sliding member 20 is in the second state. Thus, the sliding member 20 that has moved to the second position cannot easily move toward the first position. That is, it is possible to prevent the sliding member 20 from being unintentionally moved to the first position and the engagement between the sliding member 20 and the rotation stopper 9 being released. However, the claw portion 20c has an appropriate elasticity, and when the operator grips the sliding member 20 and pulls out the sliding member 20 to the first position, the tip portion is opened, and the engagement with the tip portion of the screw member 13 is stopped. It is to be released.

  A knob 20d is provided on the outer peripheral surface on the base end side of the sliding member 20. Specifically, a groove serving as a non-slip is provided. The operator can pinch or loosen the screw member 13 by pinching the knob 20d and rotating the sliding member 20. On the inner peripheral surface on the base end side of the sliding member 20, an enlarged diameter portion 20e is provided. For example, as shown in FIG. 10A, the inner diameter of the enlarged diameter portion 20e is increased so that the sliding member 20 does not collide with the antenna body 11 when the sliding member 20 moves to the first position. It is the part that is.

  As shown in FIG. 9, a rib 20f is provided on the inner peripheral surface of the sliding member 20. The rib 20f is provided to prevent rattling of the sliding member 20 that slides on the screw member 13.

  In the information processing apparatus 1 according to the present embodiment, as shown in FIG. 13A, since the sliding member 20 is located outside the antenna mounting hole 5c1, the sliding member 20 is easily picked up and easily operated. can do. When the antenna 10 is mounted, as shown in FIG. 11, the sliding member 20 is pulled out from the partition wall 5c side to the first position, and the engagement between the sliding member 20 and the rotation stopper 9 is released. The screw member 13 can be appropriately narrowed. Even when the antenna 10 is removed, the screw member 13 can be easily loosened by keeping the sliding member 20 in the same state. If the sliding member 20 is removed as shown in FIG. 13B, the screw member 13 is located in the antenna mounting hole 5c1, so that the operation of the screw member 13 becomes difficult. As a result, the screw member 13 cannot be properly narrowed down, and the antenna 10 easily falls off. Also, it becomes difficult to remove the antenna 10. In the information processing apparatus 1 of the present embodiment, such inconvenience can be solved.

  In addition, the information processing apparatus 1 of the present embodiment pushes the sliding member 20 toward the partition 5c to the second position, as shown in FIG. 12, and engages the sliding member 20 with the rotation stopper 9. Thereby, the loosening of the screw member 13 meshed with the sliding member 20 can be prevented. Therefore, even if the information processing apparatus 1 is subjected to vibration, or the antenna 10 is rotated or bent, the antenna 10 is prevented from being loosened.

  Although the preferred embodiment of the present invention has been described in detail, the present invention is not limited to the specific embodiment, and various modifications and changes can be made within the scope of the present invention described in the appended claims. Changes are possible.
