And a circular accommodating portion 37b having a diameter slightly larger than the diameter of the first container.

  Thus, by shifting the position where the second bearing portion 37 is provided to the opening side of the housing groove 16 with respect to the first bearing portion 36, the thickness of the apparatus main body 30 (in the left-right direction of FIG. (Thickness) can be reduced. In addition, since the second gear 60 can be disposed near the opening of the receiving groove 16, the length of the support portion 15 b can be shortened in the moving direction of the gap closing device 15.

  When the shaft portion 63 of the second gear 60 is fitted into the second bearing portion 37, the side wall of the retaining portion 37a is bent and the width of the retaining portion 37a is widened to allow the second gear 60 to be inserted. Then, the pair of shaft portions 63 of the second gear 60 can be fitted into the pair of accommodating portions 37b, respectively. On the other hand, after the shaft portion 63 is fitted into the accommodating portion 37b, the retaining portion 37a is pulled out in a direction opposite to the fitting direction of the pair of shaft portions 63 (second gear 60) unless the side wall is bent. To prevent. Here, the accommodating portion 37b has a circular shape with a slightly larger diameter than the shaft portion 63 of the second gear 60, and the accommodating portion 37b advances and retracts the gap closing member 15 of the second gear 60 (FIG. 7 ( The movement in the vertical direction in a) and the direction orthogonal to the forward / backward direction of the gap closing member 15 (left-right direction in FIG. 7A) is restricted.

  The first and second gears 50 and 60, and the first and second bearing portions 36 and 37 are configured such that the shaft portions 53 and 63 of the first and second gears 50 and 60 are the first and second bearing portions. In the state of being fitted in 36, 37, the gear portion 51 of the first gear 50 and the gear portion 61 of the second gear 60 are always meshed, and the gear portion 61 of the second gear 60 and the gap closing member 15 are It is comprised so that the tooth | gear part of the rack part 15c may always mesh | engage. Thereby, the 1st gear 50 and the 2nd gear 60 rotate in cooperation always.

  When attaching the coil spring 70, as shown in FIG. 3 (b), first, with respect to the pair of coil support portions 35a of the apparatus body 30, the coil portion 72 of the coil spring 70 is placed on the coil support portion 35a from the outside.

As a result, the first gear 50 is urged toward the cap portion 31 of the apparatus main body 30 (left side in FIGS. 7A and 7B).

(Adjustment operation of protrusion amount of gap closing member)
Next, an operation of adjusting the protrusion amount of the gap closing member 15 by the adjusting device 20 according to the embodiment will be described with reference to FIG.

  First, adjustment of the protrusion amount of the gap closing member 15 is unnecessary, and when the operation portion 52 of the first gear 50 is not operated, the first gear 50 is moved by the coil spring 70 as shown in FIG. Since the urging force in the left direction is applied in FIG. 8A, the urging force of the coil spring 70 causes the gear portion 51 of the first gear 50 to engage with the locking portion 32 a of the apparatus main body 30. It is biased and held in the restricting position. At this time, the gear portion 51 of the first gear 50 and the gear portion 61 of the second gear 60, and the gear portion 61 of the second gear 60 and the tooth portion of the rack portion 15c of the gap closing member 15 are engaged with each other. Yes.

  Thus, in the case of non-operation, since the gear portion 51 of the first gear 50 is engaged with the locking portion 32a of the apparatus body 30, the first and second gears 50 and 60 are rotated. Be regulated. As a result, the sliding operation of the gap closing member 15 is also restricted. Here, as shown in FIGS. 3A and 3B, the locking portion 32 a of the apparatus main body 30 and the gear portion 51 of the first gear 50 are perpendicular to the advancing and retreating direction of the gap closing member 15 ( The left and right sides in FIG. 3 are engaged on the left and right sides. By setting it as such a structure, rotation of the 1st and 2nd gears 50 and 60 can be more reliably and stably controlled in a control position.

  Next, when the operator adjusts the protruding amount of the gap closing member 15, first, the operator pushes the operating portion 52 of the first gear 50 in the restricted position against the biasing force of the coil spring 70 with a finger (see FIG. 8 to the right). By this operation, the first gear 50 moves to the right in FIG. 8B, and the engagement between the gear portion 51 of the first gear 50 and the locking portion 32a of the apparatus main body 30 is released (FIG. 8). 8 (b) is a view showing a state in which the engagement is released. In other words, the first gear 50 moves to a release position where the engagement between the gear portion 51 and the locking portion 32a of the apparatus main body 30 is released. At this time, the gear portion 51 of the first gear 50 and the gear portion 61 of the second gear 60, and the gear portion 61 of the second gear 60 and the tooth portion of the rack portion 15c of the gap closing member 15 are engaged with each other. Yes.

  Next, the operator turns the operation unit 52 in the forward / backward direction (vertical direction in FIG. 8B) of the gap closing member 15 while pushing the operation unit 52 of the first gear 50 into the release position. By operating, the protrusion amount of the gap closing member 15 can be adjusted. That is, when the gear portion 51 is rotated by the operation of the first gear 50, the second gear 60 meshed with the gear portion 51 by the gear portion 61 is rotated, and the second gear 60 is rotated. The rack portion 15c meshed with the gear portion 61 moves to the gear portion 61, and the gap closing member 15 advances and retreats to change the protruding amount. 2 and 8 show an example in which the protruding amount of the gap closing member 15 can be adjusted in five steps. In addition, adjustment of protrusion amount may be more than five steps, and may be less.

  When the adjustment of the protrusion amount of the gap closing member 15 is finished, the operator releases his / her finger from the operation portion 52 of the first gear 50. Then, as in the state before the operation, the first gear 50 is biased to the restriction position where the gear portion 51 engages with the locking portion 32 a of the apparatus main body 30 by the biasing force of the coil spring 70. In the restricting position, the sliding operation of the gap closing member 15 is also restricted by the engagement of the first and second gears 50 and 60 and the rack portion 15c. That is, the adjustment position of the gap closing member 15 is maintained.

  As described above, according to the present embodiment, it is possible to provide a gap closing member adjusting device that can easily adjust the position of the gap closing member in the advancing / retreating direction and can maintain the adjustment position.

  Further, by using the first and second gears 50 and 60 for the pinion part 40, the operation direction of the operation part 52 of the first gear 50 and the adjustment direction of the gap closing member 15 can be made the same direction. it can.
