Further, two pieces are provided on the other side 2406 at predetermined intervals in the length direction of the side 2406, respectively, with the abutting plate 36 interposed therebetween. Further, in the present embodiment, the abutment block 30 constituting the positioning means 26 is formed in a square shape in a plan view as described in detail with reference to FIG. Protrusions 3002 and 3004 to which the pin 34 is attached are provided in a protruding manner, and a long abutment pin 3402 is provided on one protrusion 3002.
Is attached, and a short butting pin 3404 is attached to the other protrusion 3004.

Then, these butting pins 3402,
3404 is a threaded portion 340 formed at the base end thereof.
6, 3408, the protrusions 3002 and 3004.
The butting block 3 by being screwed onto the
0, and the screw portion 340
The fixing nut 38 screwed to the screws 6 and 3408 is fixed to the protrusions 3002 and 3004 by being brought into contact with the protrusions 3002 and 3004. Also,
These abutting pins 3402 and 3404 are made to project from the abutting block 30 in opposite directions, that is, at a position of the base 24 on which the abutting block 30 is mounted, at intervals of 180 degrees around an axis orthogonal to the base 24. Has been.

The abutting pins 3402 and 34 are also provided.
04 is rotated about the axis, so that the butting block 3 of these butting pins 3402, 3404
The protrusion length from 0 can be changed, and in the present embodiment, the screw portions 3406 and 3408 constitute a position adjusting mechanism. Further, a spherical resin shell-shaped contactor 40 made of a hard resin is attached to the protruding ends of the abutting pins 3402 and 3404.

In the present embodiment, the fixed block 32 is formed in an L shape so as to be in contact with the two side surfaces of the corner of the butting block 30, and
As shown in FIG. 3B, three pieces are provided corresponding to the three corners of the butting block 30, and are integrally fixed on the butting plate 36. Therefore, the abutment block 30 is restrained from moving in the plane direction of the base body 24 by being inserted between the fixed blocks 32 from above, and the relative movement around the axis orthogonal to the base body 24 is restrained. It is supposed to be restrained. In addition, the abutting block 30 is provided around the axis line 18
It can be inserted and fixed between the fixed blocks 32 at a position rotated by 0 degree.

Further, in this embodiment, the engaging hole 3006 is formed in the side surface of the butting block 30, and as shown in FIG. 3B, the diagonally opposite corner of the butting block 30 is provided. The fixed block 32 positioned at the above portion has a through hole 32 that is fitted to the locking hole 3006 in a state where the fixed block 30 is inserted.
02 is formed. A retaining pin 42 for preventing the abutment block 30 from coming off the fixed block 32 is inserted into the through hole 3202 and the locking hole 3006. The through hole 3202 and the locking hole By 3006 and the retaining pin 42,
The retaining means in this embodiment is configured.

Next, the operation of the positioning device 20 of this embodiment having the above-mentioned structure will be described. First, in order to fix the large panel 22, as shown in FIG. 1, in each positioning means 26, the abutting block 30 is moved between the fixing blocks 32 so that the short abutting pins 34 face the inside of the base body 24. After inserting, the retaining pin 42
The abutting block 30 is fixed to the base 22 by fitting the above into the through hole 3202 and the locking hole 3006. In this state, each butting block 30 is restrained from moving relative to the base body 22 both in the plane direction and in the direction orthogonal thereto.

Thus, the panel 22 is inserted between the positioning means 26 and the pressing means 28, and then the pressing means 28 is operated to operate the panel 22.
Is brought into contact with each positioning means 26, and the panel 2
2 positioning is performed.

When switching to a smaller panel 22, after pulling out the retaining pin 42, the abutting block 30 is pulled out upward so that the long abutting pin 34 faces the inside of the base body 24. Then, it is inserted again into the fixed block 32, and the retaining pin 42 is reattached. As a result, the contact position between the positioning means 26 and the panel 22 is changed to the inside of the base body 24 and the height from the base body 24 is changed. From this, by operating the pressing means 28 to bring the panel 22 into contact with the positioning means 26, the panel 22
Is performed.

As described above, according to the positioning device 20 of the present embodiment, the abutting block 30 is pulled out from the fixed block 32, rotated by a predetermined angle, and then inserted into the fixed block 32 again by a simple operation. The positioning position of the panel 22 is changed. Therefore, the setup work associated with the change of the panel 22 is simplified, and the working time is greatly shortened.

Further, in this embodiment, the fixed block 3 of the butting block 30 is fixed by the retaining pin 42.
The disconnection from 2 is reliably prevented, and also from this point, the displacement of the positioning position of the panel 22 is prevented. Further, the butting pin 34 is attached to the butting block 30 by the screw portion 340.
By being screwed via 6, 3408, the amount of protrusion can be finely adjusted by the pivoting operation of the abutment pin 34. Therefore, the positioning position of the panel 22 can be finely adjusted, and highly accurate positioning is possible.

The shapes, sizes, etc. of the respective constituent members shown in the above embodiment are examples, and can be variously changed based on design requirements and the like. For example, in the above-described embodiment, the abutment block 30 has a square shape, three corners thereof are abutted and supported by the fixed block 32, and abutment pins are provided from two parallel sides of the abutment block 30. Although the configuration is such that the two types of panels 22 are positioned by using the configuration in which 34 is projected, the posture change angle is reduced by making the abutment block 30 into a polygonal shape, Further, by providing the abutting pins 34 on the side surface of the abutting block 30 at the same pitch as the posture changing angle, it is possible to support three or more types of panels 22.
