As shown in FIGS. 2 and 4, this horizontal motion guide means 30 is overlapped inwardly with both ends of a stay receiver 31 to which the tip of the vertical motion guide means 10 as a connecting means is fixed, and is slidable. The rear ends of the left stay 33 and the right stay 34 with extending guide brake plates 32 that meet each other are pivoted to the rear ends 3
5, 36, and at the front ends of the left and right stays 33, 34,
Both sides of the retainer plate 37 are pivotally connected, and shaft holes 40 are formed in the retainer plate 37 at positions equidistant from the pivot joints 38 and 39 on both sides, and the brake plates 32 and 32' of the left and right stays 33 and 34 are connected to each other. Elongated holes 41, 41' are formed around the respective front end pivot parts 38, 39, with radii equal to the distance between the pivot parts 38, 39 of the retaining plate 37 and the shaft hole 40, and the small top plate A connecting shaft 42 protruding from the center of the lower surface of 4 is inserted into both the long holes 41 and the shaft hole 40 of the holding plate 37, and a brake means 43 capable of holding both the brake plates 32 and the holding plate 37 is provided at the other end. That's what happens. Here, the stay receiver 31 is mounted on a single vertical plate 4 as shown in the figure.
The upper and lower sides of 4 are bent backward into a U-shape, and a protruding piece 45 for pivoting is provided on the side end thereof, and two opposing vertical walls 46 are formed from the inside to the rear, and an axis rod is attached to the vertical wall 46. 47, and the tip of the vertical movement guide means 10 serving as the connection means is pivotally connected to the shaft rod 47. Therefore, as can be seen in FIG. movement becomes possible. Also, each stay 3
3 and 34, as shown in FIG. 4, the guide brake plates 32 and 32' are configured in a fan shape with a slight protrusion toward the front side, and the guide elongated holes 41 and 34 overlap each other on the tip side thereof. 41, and the holding plate 37 has an axial hole 40 formed in the holding plate 37 at a position where it can overlap with the position where the guide elongated holes 41, 41 overlap with each other. Therefore, in order to satisfy the above-mentioned conditions, the retaining plate 37 is made of a plate having a triangular planar shape. The imaginary line in the figure shows the holding plate 37 in a vertically inverted state for the purpose of explanation. The brake means 43 allows the small top plate 4 to move horizontally from side to side and at the same time rotate itself,
