18, when the support member 251 is separated from the fixing portion 212 and inserted into the fixing hole 212b, the adjusting member 430 is lowered by rotation And the support member 251 can be inserted into the fixing hole 212b while being disposed below the fixing hole 212b.

At this time, the casing 443 is opened without being folded, and the pressure bar 444 is preferably received inside the casing 443 so as to minimize the degree of protrusion from the casing 443, The support member 251 can be supported while being in contact with the support member 251.

15, when the fixing member 253 is inserted into the fixing hole 212b, the unlocking preventing means 440 is fixed together with the fixing plate 420 while the adjusting member 430 is lifted and lowered by rotation, Is positioned on one side of the member 253 while being rotated about the folding member 442 as shown in Fig. 17, thereby preventing the fixing member 253 from being loosened.

That is, the casing 443 is pivoted about the folding member 442, and the upper portion of the pressure bar 444 faces the fixing member 253.

The pressing bar 444 is pulled out of the casing 443 according to the adjustment of the adjusting lever 445 so as to be in contact with the head 253a while maintaining the drawn state as the adjusting lever 430 is tightened.

Accordingly, the pressing body 441 can be prevented from being separated from the fixing member 253 while being in contact with the head portion 253a as the pressing body 441 rotates about the folding member 442 in the direction of the fixing member 253.

The release preventing portion 400 prevents the fixing member 253 for fixing the supporting member 251 to the mounting mechanism 210 from being released or released by an incomplete engagement state or an impact transmitted from the outside, So that the stable engagement state of the second engagement portion 253 can be maintained.

The above description is only an embodiment for implementing an image processing system for precisely ensuring and precisely synthesizing an image image of an unidentified feature in the digital map according to the present invention, and the present invention is not limited to the above embodiment It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. will be.
