1, 2, 3, 4, 5, and 6, the binoculars 1 are mounted integrally on the surface opposite to the mounting surface 2 d of the base unit 2 to the gantry as shown in FIG. 1. It is mounted on the mounting plate 2a. In the present embodiment, the base portion 2 and the mounting plate 2a are integrally formed of resin. The base portion 2 has a female screw 2b screwed onto a mounting screw 2d (not shown) on the mounting surface 2d. The mounting plate 2a is made of resin and has flexibility, and as shown in FIG. 6, the whole is not flat, and the rear portion (the mounting portion of the eyepiece) is raised one step higher. A cutout portion 2c is formed at the rear end of the portion to prevent contact with the nose. The front flat portion is provided with two through holes 2e that are distributed to the left and right in a direction perpendicular to the optical axis of the binoculars to be placed. A drive shaft 5 extending downward is planted on the back of the mounting plate 2a at the center of the left / right distribution, and a drive male screw is threaded on the outer diameter thereof. . Further, a buffer holding plate 3 for softly mounting the binoculars 1 is fixed on the upper surface of the mounting plate 2a.
[0014]
Upright pillars 7 constituting the side portions of the moving members penetrate the two through holes 2e of the mounting plate 2a. Each lower end of the upright column 7 is integrally fixed by the bottom support plate 6 so as to form a substantially U-shape. The bottom support plate 6 prevents the drive knob 4 from moving in the axial direction at a substantially central portion and holds the drive knob 4 so as to be rotatable. The drive knob 4 has a drive female screw 4 a threaded on an inner diameter portion, and is screwed into the drive male screw 5 a of the drive shaft 5.

The pressing member 9 is covered with a buffer member 10.
The binocular holding device configured as described above is used as follows.
[0016]
First, the binoculars 1 are placed on the buffer holding plate 3 on the placement plate 2a. At this time, the eyepiece part and the objective part are set to the operable position of the front pressing member 9 at the rear step part. This state is as shown in FIGS. 1 (a) and 1 (b).
When the binoculars 1 are completely placed at a desired position, the drive knob 4 is rotated. By this rotation, the bottom support plate 6 is moved away from the mounting plate 2a, that is, downward, by the action of the drive male screw 5a of the drive shaft 5 screwed into the drive female screw 4a. In response to this movement, the upright column 7 integrated with the bottom support plate 6 moves downward in the through hole 2e. Accordingly, the holding member 9 also moves downward, the buffer member 10 comes into contact with the binoculars 1, and the binoculars 1 are held and fixed. This state is as shown in FIGS. 2 (a) and 2 (b).
[0017]
