These side walls 44 a are arranged so as to face each other, and are formed longer in the radial direction around the axis O 2 than the rib member 43. These side walls 44 a have a shape close to a right triangle like the rib member 43, and are provided with a hypotenuse 44 as inclined so as to intersect both the upper fixing plate portion 40 and the upper column main body portion 39.

  The inclined wall 44b is formed so as to connect the oblique sides 44as of the two side walls 44a, and an upper retraction hole 44h capable of retracting the cable C to the outside is formed. When the axis O2 of the upper column 31 extends in the vertical direction, the outer surface of the inclined wall 44b faces obliquely downward, which is the direction away from the axis O2. The upper retraction hole 44h formed in the inclined wall 44b is also opened obliquely downward. The upper retraction hole 44 h is formed with a size that allows the end of the cable C to be retreated to the outside of the upper column 31. From the viewpoint of workability, the upper retraction hole 44h may be sized to allow the operator's hand to pass through. In addition, although the case where the upper retraction hole 44h in the first embodiment is formed in a rectangular shape is illustrated, the shape of the upper retraction hole 44h may be a shape that can retract the end portion of the cable C to the outside. Any shape may be used.

The vertical wall 44c is formed so as to connect the edge located on the upper side of the inclined wall 44b and the lower surface of the upper fixed plate portion 40 when the axis O2 extends vertically.
The horizontal wall 44d is formed so as to connect between the edge located on the lower side of the inclined wall 44b and the outer peripheral surface of the upper column main body 39 when the axis O2 extends vertically.

  The inside of the first retraction hole forming portion 44 formed in this way is communicated with the internal space of the upper column main body portion 39. More specifically, the upper column main body 39 has a notch 39b (see FIG. 4) in which the outer peripheral wall 39a is not formed between two side walls 44a arranged to face each other. Yes. The cable C passing through the upper column main body 39 can be connected to the internal space of the first retraction hole forming unit 44 from the internal space of the upper column main body 39 through the notch 39b.

  In this embodiment, the plate opening 40h of the upper fixed plate portion 40 extends to between the two side walls 44a arranged to face each other. An opening 22h (see FIG. 2) is formed in the lower plate 22d of the apparatus body 20 so as to overlap the plate opening 40h. That is, the internal space of the first retraction hole forming portion 44 does not go through the internal space of the upper column main body 39, but via the plate opening portion 40h of the upper fixing plate portion 40 and the opening portion 22h of the lower plate 22d. It communicates directly with the internal space of the apparatus body 20. The plate opening 40 h and the opening 22 h may have any shape as long as the cable C retracted in the upper retraction hole 44 h can be inserted into the apparatus main body 20.

  The first lid plate 44e has a plate shape capable of closing the upper retraction hole 44h, and can be fixed to the inclined wall 44b by a fastener such as a bolt. The first cover plate 44e in this embodiment is formed in a rectangular plate shape larger than the upper retraction hole 44h so that the upper retraction hole 44h can be closed. That is, the upper retraction hole 44h can be opened and closed by the first lid plate 44e. Note that the opening and closing of the first lid plate 44e is not limited to that performed using a fastener such as a bolt. As the mechanism for opening and closing the first cover plate 44e, any mechanism may be used as long as it can open and close the upper retraction hole 44h. In addition, the case where the inclined wall 44b and the upper retraction hole 44h are formed so as to face obliquely downward with the axis O2 extending in the vertical direction has been described. However, the direction of the upper retraction hole 44h is not limited to one that faces obliquely downward. Further, although the case where the first retraction hole forming portion 44 is formed separately from the upper strut body portion 39 has been described, the upper retraction hole 44 h may be formed in the upper strut body portion 39.

Further, in FIG. 15, illustration of the cover plate portion 33 a of the incoming line box portion 33 is omitted.

  The terminal block housing part 70 is disposed between the incoming line box part 33 and the lower support body part (support body part) 34. The terminal block accommodating portion 70 accommodates a signal terminal block 70a therein. The terminal block accommodating portion 70 in this embodiment is formed in a box shape that communicates with the lower incoming line box portion 33 and the upper lower column main body portion 34 inside the column 221. At least one of the plurality of side surfaces 70s forming the box shape can be opened and closed in the terminal block accommodating portion 70. By opening the side surface 70 s of the terminal block housing part 70, it becomes possible for an operator to perform connection work or the like on the signal terminal block 70 a housed in the terminal block housing part 70. The mechanism for opening and closing the side surface 70s may have any configuration as long as it can be opened and closed.

  The lower column main body 34 and the upper column main body 39 communicate the internal spaces of the terminal block housing unit 70 and the apparatus main body 20, respectively. The lower column main body 34 extends upward from the terminal block housing 70 and is connected to the upper column main body 39, and the upper column main body 39 is connected to the upper fixing plate unit 40. Here, in the second embodiment, as in the first embodiment, the case where the upper fixing plate portion 40 is provided is illustrated, but the upper fixing plate portion 40 is not provided, and the upper support main body portion 39 is provided.

The internal cable 72 is not directly connected to an electronic device housed in the apparatus main body 20 but is connected to another signal terminal block (not shown) installed in the apparatus main body 20. You may do it.

  Here, in the second embodiment, the apparatus main body 20 and the column 221 are installed in an integrated state. Therefore, the internal cable 72 is connected in advance between the signal terminal block 70 a and the electronic device of the apparatus main body 20. In the second embodiment, since the height of the column 221 can be adjusted, the internal cable 72 has a surplus length according to the height adjustment range of the column 221. When the height of the apparatus main body 20 can be adjusted by the lower strut 230 and the upper strut 31 as described above, when the first bolt 46 and the second bolt 47 are removed from the strut 221, the internal cable 72 Unnecessary force may act and break. Therefore, it is possible to provide a retaining structure that prevents the upper strut 31 from coming out of the lower strut 230 while keeping the height of the strut 221 adjustable. As this retaining structure, wires (metal wires) having the length of the support column 221 when the height of the support column 221 is adjusted to be the highest are respectively connected to the upper portion of the upper support column 31 and the lower portion of the lower support column 230. A structure to be fixed can be exemplified. When such a wire is used, even if the height of the support column 221 is lowered, the wire bends, so that the height adjustment of the support column 221 is not hindered.

The vehicle number recognition device 211 of the second embodiment has the above-described configuration. Next, the installation method of the vehicle number recognition apparatus 211 of this 2nd embodiment is demonstrated, referring drawings.
