The plate and the second guide plate are connected to each other so as to be rotatable (see FIGS. 7 and 10 described later). The guide base 33 shown in FIG. 5 is a substantially rectangular member that is attached to the inner surface of the corresponding edge portion over the entire vertical length of the moving portion 23, and the rotation shaft 26 passes through the rear edge portion thereof. A hinge piece 33a is provided. The guide plate 34 shown in FIG. 6 has the same length as the guide base 33 and shields the gap S2 between the left and right edge portions of the screen 5 (and the weight bar 6) and the left edge portion 11b or the right edge portion 11c facing it. The hinge piece 34a which penetrates the rotating shaft 26 is provided in the edge part. In the example of the present embodiment shown in the figure, the guide plate 34 of the moving unit 23 overlaps the guide base 33 with the hinge pieces 33a and 34a in the vertical direction at the edge on the rear side (outside of the screen 5). In addition, the guide plate 34 is rotatably connected around the rotation shaft 26 by passing through the rotation shaft 26 made of a wire-like fine metal wire. Although not particularly illustrated, the rotation shaft 26 and the guide plate 34 may be disposed at the edge of the guide base 33 on the front side (the interior side of the screen 5), or both the rear and front edges.

<Configuration of the rotation suppression unit>
FIG. 8 is an external view of the rotation suppressing unit 25 in an enlarged perspective view. In FIG. 8, the rotation restraining portion 25 is entirely made of a resin such as plastic that can be easily molded, and has a flat plate portion 42 having a shaft hole 41 through which the rotation shaft 26 can penetrate, and the whole. A holding portion 43 having a substantially rectangular parallelepiped shape is integrally provided. The holding portion 43 has a width in the left-right direction that is set to a dimension that can be inserted into the guide base 33 of the moving portion 23. In the illustrated example, a groove 44 along the up-down direction is formed on the side surface in the left-right direction. Is formed. The flat plate portion 42 is provided at a substantially central position in the vertical direction on the rear rear side of the holding portion 43.

  As shown in FIG. 3, the rotation suppressing unit 25 inserts the holding unit 43 into the guide base 33 of the moving unit 23 from the rear rear side, and the left edge portion 11 b or the right side inside the guide base 33. It is sandwiched and fixed with the edge portion 11c. Further, the flat plate portion 42 is sandwiched in the vertical direction between the hinge pieces 33 a and 34 a of the guide base 33 and the guide plate 34 in the moving portion 23 and penetrates the rotating shaft 26. Accordingly, the position of the flat plate portion 42 in the vertical direction is fixed, and the posture and arrangement around the rotation shaft 26 are fixed by the holding portion 43. The flat plate portion suppresses the rotation of the guide plate 34 by its contour shape as described later.

  FIG. 9 is a plan view of the connected state of the rotation suppressing unit 25 and the guide plate 34 as viewed from above. In FIG. 9, a large-diameter portion 45 is formed on the outer peripheral edge portion of the flat plate portion 42 of the rotation suppressing portion 25. The large-diameter portion 45 has a minimum turning radius R1 of the guide plate 34 centered on the turning shaft 26 (that is, the portion of the surface of the guide plate 34 excluding the hinge piece 34a closest to the center of the turning shaft 26). It is formed so as to be able to contact the guide plate 34 with a projection radius R2 that is slightly larger than the distance from the center of the moving shaft 26). And this large diameter part 45 is provided with only one so that protrusion radius R2 may be located in the approximate center of the rotation angle range A (in this example about 90 degrees) of the guide plate 34. The large-diameter portion 45 has small-diameter portions 45a formed by so-called round chamfering at both ends in the circumferential direction of the rotating shaft 26, and the small-diameter portion 45a having a radius smaller than the protruding radius R2 The guide plates 34 and 34 'are in contact with the limit positions at both ends of the moving angle range A, respectively.

<Function of the rotation suppression unit>
With reference to FIG. 10, it will be described what kind of rotation operability occurs in the guide plate 34 of the moving unit 23 in the vertical guide unit 21 of the present embodiment by including the rotation suppressing unit 25 having the above configuration. To do. First, as described above, the guide plate 34 of the moving unit 23 is opened in a parallel state with the guide base 33 as shown in FIG. 10C from the closed state standing upright with the guide base 33 as shown in FIG. It can be rotated in a rotation angle range A of about 90 ° up to the state. Among these, in each of the closed state of FIG. 10A and the open state of FIG. 10C at both end limit positions of the rotation angle range A, the guide plate 34 contacts the small diameter portion 45a having a relatively small radius. Therefore, since the arrangement is lowered with respect to the center of the rotation shaft 26, the state is relatively stable.

  However, in a transition state when switching between the closed state and the open state, that is, a state in the middle of turning as shown in FIG. 10B, the guide plate 34 protrudes slightly larger than the minimum turning radius R1. It abuts on the outer peripheral tip of the large diameter portion 45 corresponding to the radius R2. At this time, since the difference between the minimum turning radius R1 and the protruding radius R2 is an appropriate dimensional difference, the turning shaft 26, which is a thin metal wire, bends and the guide plate 34 is allowed to escape to the outer peripheral side by the dimensional difference. By riding on the diameter part 45, it can finally be rotated. However, during this time, since the force due to the deflection of the rotating shaft 26 is received, the state is relatively unstable.

  As described above, when turning the guide plate 34 so as to switch from the closed state to the open state, or when turning the guide plate 34 so as to switch from the open state to the closed state, a certain amount of rotational force is required. This required rotational force can be adjusted by the difference in size between the minimum turning radius R1 and the protruding radius R2, the thickness dimension of the flat plate portion 42 of the turning restraining portion 25, the number of installed turning restraining portions 25, and the like. Therefore, it is possible to provide a rotation operation with an appropriate click feeling. The dimensional difference between the minimum turning radius R1 and the protruding radius R2 may be about 0.2 mm, for example, although it depends on the overall size of the vertical guide portion 21. Further, the required rotational power also increases in proportion to the thickness dimension of the flat plate portion 42 of the rotation suppressing portion 25 and the number of the rotation suppressing portions 25 installed.

  Further, with respect to the transition state of FIG. 10B, the guide plate 34 falls with respect to the center of the rotating shaft 26 in each of the closed state of FIG. 10A and the open state of FIG. Therefore, the rotation position can be stably maintained unless the rotation operation is performed (unless the turning force is applied).
