[Move procedure]
Next, a procedure for horizontally moving the second measurement unit 3 placed on the placement table 36 during maintenance work will be described with reference to the drawings. In the present embodiment, from the state of FIG. 1, maintenance work is performed with the one side surface 3 c of the second measurement unit 3 facing the sample transport device 4 side (Y1 direction side), and the other side surface of the second measurement unit 3. A description will be given separately for the case where maintenance work is performed in a state where 3d is directed to the sample transport device 4 side (Y1 direction side). In addition, since the movement procedure of the 1st measurement unit 2 is performed in the same procedure as the 2nd measurement unit 3, it abbreviate | omits about the detailed description.

  In FIG. 1, when performing maintenance work in a state where the one side surface 3c of the second measurement unit 3 is directed to the sample transport device 4 side (Y1 direction side), first, the mounting table 36 of the second measurement unit 3 by the bolts 11 and 13 is used. The fixation to the sample transport device 4 is released, and the second measurement unit 3 is brought into a state in which the second measurement unit 3 can be moved horizontally on the mounting table 36. At this time, the bracket 12 is also removed from the mounting table 36 together with the bolt 13.

  FIG. 8A is a schematic plan view of the second measurement unit 3 in the state of FIG. After the second measurement unit 3 is released, when the second measurement unit 3 is pushed in the Y2 direction from the sample transport device 4 side (Y1 direction side) from the state of FIG. By moving along the part 38b, the second measurement unit 3 moves horizontally in the Y2 direction. Then, as shown in FIG. 8B, when the protruding portion 3k moves to the second guide portion 38c, the horizontal movement of the second measurement unit 3 in the Y2 direction is restricted. In this state, since the front surface 3a of the second measurement unit 3 is separated from the fixed plate 36f of the mounting table 36 in the Y2 direction, the second measurement unit 3 can be rotated in the horizontal direction without interfering with the fixed plate 36f. It becomes.

  Next, the second measurement unit 3 is rotated horizontally from the state of FIG. 8B around the protrusion 3k in the clockwise direction when viewed from the top. Then, as shown in FIG. 8C, when the leg 3g of the second measurement unit 3 moves horizontally to the X1 direction side end on the mounting table 36, the second measurement unit 3 rotates horizontally in the clockwise direction. Is temporarily stopped.

  From the state of FIG. 8C, the second measurement unit 3 is rotated horizontally in the clockwise direction while horizontally moving in the X2 direction. At that time, the protruding portion 3k moves in the X2 direction along the second guide portion 38c, and reaches the connecting portion with the first direction changing portion 38d as shown in FIG. 8 (d).

  When the second measurement unit 3 is further pushed in the X2 direction from the state of FIG. 8D, the protrusion 3k moves along the first direction changing portion 38d, so that the second measurement unit 3 is Move horizontally while changing direction from the X2 direction to the Y1 direction toward the upper left of e).

  Then, as shown in FIG. 9 (f), when the one side surface 3 c of the second measurement unit 3 is directed toward the sample transport device 4, the rotation of the second measurement unit 3 in the clockwise direction is stopped.

  When the second measurement unit 3 is further pulled in the Y1 direction from the state of FIG. 9G, the second measurement unit 3 horizontally moves in the Y1 direction along the third guide portion 38e, as shown in FIG. 9H. As described above, the one side surface 3c of the second measurement unit 3 can be brought closer to the sample transport device 4 side. Thereby, maintenance work inside the unit can be performed from the one side surface 3c of the second measurement unit 3 on the sample transport device 4 side.

  Next, the case where the maintenance work is performed in the state where the other side surface 3d of the second measurement unit 3 is directed to the sample transport device 4 side (Y1 direction side) from the state of FIG. 1 will be described. First, as in the case of performing maintenance work on the other side surface 3d of the second measurement unit 3, the fixing of the second measurement unit 3 to the mounting table 36 and the sample transport device 4 with the bolts 11 and 13 is released, and the second measurement unit 3 is released. Is in a state in which it can move horizontally on the mounting table 36. At this time, the bracket 12 is also removed from the mounting table 36 together with the bolt 13.

  FIG. 10A is a schematic plan view of the second measurement unit 3 in the state of FIG. After the second measurement unit 3 is released, when the second measurement unit 3 is pushed in the Y2 direction from the sample transport device 4 side (Y1 direction side) from the state of FIG. By moving along the part 38b, the second measurement unit 3 moves horizontally in the Y2 direction.

  Then, as shown in FIG. 10B, when the protruding portion 3k moves to the second guide portion 38c, the horizontal movement of the second measuring unit 3 in the Y2 direction is restricted. In this state, since the front surface 3a of the second measurement unit 3 is separated from the fixed plate 36f of the mounting table 36 in the Y2 direction, the second measurement unit 3 is rotated in the horizontal direction while avoiding contact between the second measurement unit 3 and the fixed plate 36f. Is possible.

  Next, the second measurement unit 3 is rotated horizontally from the state shown in FIG. 10B in the counterclockwise direction when the second measurement unit 3 is viewed from above around the protrusion 3k. Then, as shown in FIG. 10 (c), when the leg portions 3h and 3j of the second measurement unit 3 move horizontally to the X2 direction side end and the Y2 direction side end on the mounting table 36, respectively, the second measurement unit 3 The horizontal rotation of the unit 3 in the counterclockwise direction is temporarily stopped. At that time, the movement of the leg portion 3h in the X2 direction is restricted by contacting the movement restricting portion 37.

  When the second measurement unit 3 is moved horizontally in the X1 direction from the state of FIG. 10C, the protrusion 3k moves in the X1 direction along the second guide portion 38c, as shown in FIG. 10D. At the same time, it reaches the connecting portion with the second direction changing portion 38f. From this state, when the second measurement unit 3 is further pushed in the X1 direction, the protrusion 3k moves along the second direction changing portion 38f, so that the second measurement unit 3 is located at the upper right in FIG. 11 (e). Toward, it moves horizontally while changing the direction from the X1 direction to the Y1 direction.

  Then, as shown in FIG. 11 (f), when the other side surface 3d of the second measurement unit 3 is directed toward the sample transport device 4, the counterclockwise rotation of the second measurement unit 3 is stopped. At the same time, the second measurement unit 3 is pulled in the Y1 direction from the sample transport device 4 side, and the projecting portion 3k is moved along the second direction changing portion 38f to the connection portion with the fourth guide portion 38g.

  When the second measurement unit 3 is further pulled in the Y1 direction from the state of FIG. 11 (f), the protruding portion 3k moves in the Y1 direction along the fourth guide portion 38g, as shown in FIG. 11 (g). The other side surface 3d of the second measurement unit 3 can be brought closer to the sample transport device 4 side. Accordingly, maintenance work inside the unit can be performed from the other side surface 3d of the second measurement unit 3 on the sample transport device 4 side.

Therefore, the load of the measurement unit 2 (3) can be supported by the legs 2g to 2j (3g to 3j). Thereby, since it can suppress that the load of the measurement unit 2 (3) concentrates on the protrusion part 2k (3k), horizontal movement and rotation to the horizontal direction of the measurement unit 2 (3) are performed smoothly. Can do.

  Further, since the outer peripheral diameter D1 of the leg portions 2g to 2j (3g to 3j) of the measurement unit 2 (3) is set larger than the dimensions D2 and W of the guide hole 28 (38), the measurement unit 2 ( When rotating 3) in the horizontal direction, it is possible to prevent the legs 2g to 2j (3g to 3j) from dropping into the guide hole 28 (38).

  Further, when the measurement unit 2 (3) is rotated in the horizontal direction, the horizontal movement range of the legs 2g to 2j (3g to 3j) is restricted by the movement restriction unit 27 (37) of the mounting table 26 (36). Therefore, contact between the measurement unit 2 (3) and the adjacent wall or other device can be more effectively avoided.
