As is well known, the sensor unit 3 detects a suspicious person intruding into the detection area by emitting a laser beam, for example, horizontally toward the detection area and detecting the reflected light. In addition, photographing within the detection area is performed by the camera unit 4, and the photographed image is displayed on a monitor (not shown) installed in the building. Individual identification by the radio waves of the intruder is performed by the tag reader unit 5. When it is detected by the sensor unit 3 that someone has entered the detection area, the tag reader unit 5 outputs a radio wave communicating with the RFID tag, and when a response radio wave is not received, the tag reader unit 5 When a response radio wave is received from an RFID tag having ID information registered in advance, the intruder is determined to be a pre-registered person and not a suspicious person.

  In order to attach the sensor unit 3, the camera unit 4, and the tag reader unit 5 to the outer wall surface 2, the security device 1 includes an attachment base 6. The mounting base 6 has a rectangular shape that is long in the vertical direction. When the outer wall surface 2 side is the back (rear) side, the mounting base 6 is mounted on the outer wall surface 2 of the building so that the front surface that is the mounting surface is the front side. The sensor unit 3, the camera unit 4 and the tag reader unit 5 are mounted side by side in the vertical direction on the mounting surface (front surface). A cover 7 is detachably attached to the sensor unit 3, the camera unit 4, and the tag reader unit 5 as long as their functions are not impaired.

  The sensor unit 3 can adjust the emitting direction of the laser beam to the elevation direction with the mounting base 6 fixed to the outer wall surface 2. The sensor unit 3 is fixed to the mounting base 6 via an angle adjustment mechanism 8 so that the laser beam emission direction can be adjusted in the elevation direction. The angle adjusting mechanism 8 will be described below.

  The angle adjustment mechanism 8 is mainly composed of an angle adjustment plate 9 as an angle adjustment member. The angle adjustment plate 9 is formed from a wide portion 3a at the center in the vertical direction of the sensor unit 3 as shown in FIGS. It is formed in a rectangular shape that is slightly smaller than the rear surface of the portion extending over the upper half 3b.

  In this case, the through hole 3e of the upper mounting portion 3c of the sensor portion 3 is a round hole, but the through holes 3f of the left and right mounting portions 3d are elongated holes on the left and right sides. In a state where the mounting screw 10 is passed through the through hole (long hole) 3f of the left and right mounting portions 3d, the mounting screw 10 passed through the upper mounting portion 3c can be rotated in the left-right direction. Then, the vertical degree of the sensor unit 3 can be adjusted by the left and right rotation of the sensor unit 3, and when the mounting base 6 is mounted on the outer wall surface 2, the mounting base 6 is tilted slightly from the normal vertical state Even if the laser beam is scanned left and right by adjusting the verticality of the sensor unit 3, it is scanned in the horizontal plane.

  On the upper side of the angle adjusting plate 9, semicircular engaging pieces 11 projecting rearward are formed on the left and right sides of the mounting piece 9a. In addition, projecting pieces 12 bent at a right angle toward the rear are formed at the lower ends of the left and right sides of the angle adjusting plate 9, and screw holes 12a are formed in the pair of projecting pieces 12. . Here, when the sensor unit 3 is attached to the angle adjusting plate 9, the projecting piece 12 is positioned at substantially the same height as the wide portion 3a, as shown in FIG.

  On the other hand, the mounting base 6 has a support plate portion 13 at which the sensor portion 3, the camera portion 4 and the tag reader portion 5 are attached, and side plates 14 projecting rearward are provided on the left and right side edges of the support plate portion 13, respectively.

And the rear side of the support plate part 13 is made concave by the side plates 14 respectively present on the left side edge and the right side edge of the support plate part 13, and the concave part 15 is closed by the removable back plate 16. It has become.

  In the support plate portion 13 of the mounting base 6, a band-shaped recess 13 a extending in the lateral direction is formed in a predetermined range above the upper end portion of the position where the angle adjusting plate 9 is disposed, and a pair of lower-end portions of the band-shaped recess 13 a A horizontally long through hole 17 is formed. A support shaft portion (pivotal support portion) 18 having a circular cross section protruding rearward is formed at the lower opening edge of the through hole 17. In addition, a pair of vertically long through holes 19 are formed on both the left and right sides of the lower end portion of the support plate portion 13 where the angle adjusting plate 9 is disposed.

  By the way, in the lower part of the upper half part 3b, the sensor part 3 is substantially widened by the lateral protrusion of the left and right mounting parts 3c, and has a wide width equivalent to the wide part 3a. The upper part of the lower half part 3g has an inverted C-shaped shape in which the width of the wide part 3a gradually decreases downward. And among the arrangement | positioning parts of the sensor part 3 in the support plate part 13, about the site | part arrange | positioned from the attaching part 3d to the upper part of the lower half part 3g, the lateral width is expanded, This support plate part 13 The left and right side plates 14 of the widened portion 13b are bulged portions 14a that bulge outward. Moreover, about the site | part in which the lower half part 3g of the sensor part 3 is arrange | positioned among the support plate parts 13, the rib 13c surrounding this is formed in the side plate 14, and protrudes ahead.

  And the recessed part 20 is formed in the part located in the right-and-left both sides of the through-hole 19 among the bulging parts 14a of a pair of right and left side plates 14, The formation of this recessed part 20 forms the swelling of the left and right both-side plates 14. A part of the projecting portion 14a is partially close to the through hole 19 from the outside. A long hole 21 is formed in a portion of the side plate 14 adjacent to the through hole 19, that is, a portion corresponding to the inner surface of the recess 20. A fixing screw 22 that is screwed into the screw hole 12a of the projecting piece 12 is passed through the long hole 21. As will be described later, when the hooking piece 11 is hooked on the support shaft portion 18, an angle adjusting plate is obtained. 9 is rotatable about the support shaft 18, the elongated hole 21 extends in the front-rear direction, that is, along the rotation locus centering on the support shaft 18 of the screw hole 12 a. Yes.

  The angle adjusting plate 9 is configured to pass the engaging piece 11 through the hole 17 so as to hang the engaging piece 11 on the support shaft portion 18, and thereby rotate in the front-rear direction around the support shaft portion 18. It will be supported as possible. Further, when the hooking piece 11 is hung on the support shaft portion 18, the protruding piece 12 is passed through the through hole 19 of the support plate portion 13, whereby the protruding piece 12 protrudes from the through hole 19 into the recessed portion 15, The side plate 14 is in contact with the back surface of the portion corresponding to the inner surface of the recessed portion 20. In addition, the part below the support shaft part 18 of the support plate part 13 inclines so that it may incline back as it goes below, and the sensor part 3 centers on the support shaft part 18 by this inclination and the strip | belt-shaped recessed part 13a. It can be rotated within a predetermined angle range in the elevation direction.

  The operation of adjusting the laser beam emission direction to the elevation direction is performed after the attachment base 6 is attached to the outer wall surface 2. That is, after the mounting base 6 is fixed to the outer wall surface 2, the engaging piece 11 of the angle adjusting plate 9 to which the sensor unit 3 is fixed is hung on the support shaft 18. Then, the angle adjusting plate 9 can be rotated in the front-rear direction around the support shaft portion 18. Therefore, when the angle adjustment plate 9 is rotated back and forth around the support shaft portion 18, the laser beam emission direction changes to the elevation direction when the angle adjustment plate 9 is rotated forward, and conversely the angle adjustment. When the plate 9 is rotated backward, the angle changes in the depression direction, so that the rotation angle of the angle adjustment plate 9 is adjusted so that the direction in which the laser beam enters the office is horizontal. After the adjustment, the fixing screw 22 is passed through the long holes 21 of the left and right side plates 14, and the fixing screw 22 is screwed into the screw hole 12a of the projecting piece 12 to be fastened and fixed. Thereby, the angle adjustment plate 9 is fixed to the side plate 14 at the prepared rotation angle.

  Here, the protruding piece 12 is provided at a position above the left and right mounting pieces 9 b of the angle adjusting plate 9, or conversely, the angle adjusting plate 9 is lengthened until it reaches the lower end portion of the sensor unit 3 and the protruding piece 12. Is provided at a portion corresponding to the wide portion 3a in the central portion of the sensor portion 3 without being provided at the lower end thereof, because the length of the long hole 21 is limited, and the adjustable angle of the angle adjusting plate 9 Therefore, there is a demand for the projecting piece 12 to be as close to the support shaft 18 as possible, and conversely, the angle adjusting plate 9 after the angle adjustment is securely secured by the fixing screw 22. In order to fix the projection piece 12 to the support shaft portion 18 as much as possible, there is a demand for the projection piece 12 to be separated from the support shaft portion 18 as much as possible. A piece 12 is provided.

  By the way, in the state which attached the mounting base 6 to the outer wall surface 2, as shown in FIG.5 and FIG.6, the tube 23 is spread | laid on the outer wall surface 2, and the front-end | tip of the said tube 23 is the lower end part of the mounting base 6 It is connected to. In the tube 23, a plurality of wiring lead wires 24 such as a power supply line and a signal line connected to a power source, a control device installed in the building, a monitor, and the like are passed. Then, as shown in FIG. 1, the lead wire 24 is introduced from the tube 23 into the concave portion 15 of the mounting base 6, and the lead plate 24 of the support plate portion 13 is formed from the extraction hole 25 formed in the belt-like concave portion 13 a of the support plate portion 13. It is led to the front side.

Although not shown, a substrate is attached to the front surface of the support plate portion 13 between the strip-shaped recess 13a and the camera portion 4 thereon, and the lead led out to the front surface side of the support plate portion 13 Line 24 is connected to the substrate. The substrate and the sensor unit 3, the camera unit 4, and the tag reader unit 5 are connected by a connector.

  According to the security device 1 configured as described above, since the protruding piece 12 of the angle adjusting plate 9 is formed so as to protrude rearward, the protruding piece 12 is located inside the left and right side surfaces of the wide portion 3a of the sensor unit 3. Can be located. That is, the distance between the pair of protruding pieces 12 can be made smaller than the lateral width of the wide portion 3 a of the sensor portion 3. For this reason, the interval between the left and right side plates 14 at the portion where the protruding piece 12 is fixed, that is, the interval between the left and right side plates 14 in the recess 20 can be made smaller than the lateral width of the wide portion 3 a of the sensor portion 3.

On the other hand, conventionally, since the projecting piece 12 is projected forward, the distance between the pair of left and right projecting pieces 12 must be larger than the lateral width of the wide portion 3a of the sensor unit 3, and in addition, the sensor unit In order for 3 to be pivotable in the left-right direction around the upper mounting portion 3 c, the distance between the pair of projecting pieces 12 must be further widened. Therefore, the support plate portion is used to fix the pair of projecting pieces 12. The distance between the pair of fixing flanges that protrudes forward from 13 has to be considerably larger than the width of the wide portion 3a of the sensor portion 3, and the support plate portion 13 must be enlarged in the width direction. .
However, in this embodiment, since the space | interval of the right-and-left both-sides board 14 in the hollow part 20 can be made smaller than the width | variety of the wide part 3a of the sensor part 3, the enlargement of the horizontal direction of the support plate part 13 is avoided. Can do.

  Further, in the present embodiment, the side plate 14 is protruded rearward so that the concave portion 15 is formed on the rear side of the support plate portion 13, so that the projecting piece 12 is accommodated and hidden in the concave portion 15. In addition, it is possible to obtain a secondary effect that the lead wire 24 can be accommodated in the concave portion 15 and hidden.

  Further, since the projecting piece 12 is fixed to the side plate 14 protruding to the rear side of the support plate portion 13, the head portion 22 a of the fixing screw 22 for fixing is positioned in the immediate vicinity of the outer wall surface 2. Therefore, even if someone tries to loosen the fixing screw 22 by applying the tip of the screwdriver 26 to the groove of the head portion 22a of the fixing screw 22 as shown in FIG. If the screwdriver 26 is not slanted, it cannot be put into the groove, and even if it can be put in the groove, it is incomplete. If the screwdriver 26 is turned in this state, the tip slips and the fixing screw 22 is moved. Unable to loosen. If the screwdriver 26 is considerably long, it will be possible to turn the tip of the screwdriver 26 into the groove of the fixing screw 22. However, since such a long screwdriver 26 cannot be concealed, the fixing screw 22 is actually used. It is considered impossible to extend to the act of loosening.
