When the fifth adjustment knob 510 is rotated, the first gear 520 is rotated so that the second gear 530 engaged therewith rotates and the cam 540 rotates at the same time. As the cam 530 rotates, as a result, the second adjusting plate 380 in contact with the upper end moves up and down (Uz direction).

Hereinafter, the operation of the panel position adjusting device 300 according to the present invention will be described with reference to the function of the adjustment knobs 410, 420, 430, 440, 510.

When the head portion 410a of the first adjustment knob 410 is rotated by a driver or manually, the first adjustment knob 410 is rotated in place without moving in the left and right directions (Ux directions), and the first adjustment is performed. The first cam 414 coupled to the threaded portion 410d of the knob 410 moves in the left and right directions (Ux directions). At this time, the inclined surface of the first cam 414 is in contact with the lower end of the third bent portion 328 of the holder 320, the first and second support brackets (320) formed on the holder support plate 340 ( 344, 346 pivot in the Θy direction about the hinge axis, wherein the spring 329 presses the holder 320 in the Θy direction (particularly, clockwise in the figure). The angle of the Θy direction of the panel 310 is adjusted by turning the holder 320, in which the panel 310 is fixed, in the Θy direction by adjusting the first adjustment knob 410.

When the second adjustment knob 420 is rotated, the second adjustment knob 420 is rotated in place without moving in the left-right direction (Ux direction), and the first adjustment knob 420 is coupled to the threaded portion 420d of the second adjustment knob 420. 2 As the distance between the first bracket 386 of the adjustment plate 380 and the second adjustment knob bracket 3540 of the first adjustment plate 350 is closer or further away, the position of the second adjustment plate 380 is increased. The first adjustment plate 350 moves in the longitudinal direction (Ux direction) while being fixed. At this time, the guide bent portion 384 of the second adjustment plate 380 is the first adjustment plate 350 in the longitudinal direction (Ux direction) on the second adjustment plate 380 by the rotation of the second adjustment knob 420 When moving to the first and second side plates (360, 370) in contact with the bent portions (364, 374), respectively, to guide the movement of the first adjustment plate (350). The middle plate 330 is kept in a fixed position together with the second adjustment plate 380, and the first and second guide pins 345 and 347 are slit 352k in the width direction of the first adjustment plate 350. ), The guide slit 362c of the first side plate 360, and the width direction slit 372c of the second side plate 370, respectively, through the second adjustment plate 350 in the longitudinal direction (Ux direction). The holder support plate 340 mounted so as not to move is moved in the longitudinal direction (Ux direction) together with the first adjustment plate 350 by the adjustment of the second adjustment knob 420. As the holder supporting plate 340 moves in the longitudinal direction (Ux direction), the holder 320 pivotally mounted to the holder supporting plate 340 and the panel 310 fixed to the holder 320 are longitudinally oriented. Move to (Ux direction).

When the third adjustment knob 430 is rotated, the screw 366 is guided by the slit 362a of the first side plate 360, and the first guide pin 345 of the holder support plate 340 is first. Guide slit 362c of first side plate 360 and slit 352k formed in adjustment plate 350 are guided. At this time, the distance between the first side bracket 368 of the first side plate 360 and the first side bracket 368 of the first adjustment plate 350 is increased or closer, and the first The holder support plate 340 moves in the width direction (Uy direction) with respect to the first adjustment plate 350 by the one guide pin 345. The first adjustment plate 350 is adjusted by the guide bent portion 384 of the second adjustment plate 380 and the bent portions 364 and 374 of the first and second side plates 360 and 370. Since the plate 350 and the first and second side plates 360 and 370 are mounted so as not to move in the width direction, the first and second adjustment plates 350 and 380 are rotated when the second adjustment knob 420 is rotated. ), The middle plate 330, and the holder supporting plate 340, the holder 320, and the panel 310 have a width while the positions of the first and second side plates 360 and 370 are fixed. Direction (Uy direction).

When the fourth adjustment knob 440 is rotated and adjusted, the distance between the second side brackets 378 of the second side plate 370 increases or decreases, and the second or second portion of the first adjustment plate 350 is adjusted. Screws 378 coupled to the cavity 352i are respectively guided by the longitudinal slits 372a of the second side plate 370 and move in the longitudinal direction (Uz direction) relative to the second side plate 370. do. At this time, the holder support plate 320 is Θz around the first guide pin 345 passing through the slit 352k of the first adjustment plate 350 and the guide slit 362c formed in the first side plate 360. Rotate in the direction.

When the fifth adjustment knob 510 is rotated, the first gear 520 is rotated so that the second gear 530 engaged therewith rotates and the cam 540 rotates at the same time. As the cam 530 rotates, as a result, the second adjusting plate 380 in contact with the upper end moves up and down (Uz direction). In this case, the second pins 388d fixed to the guide bar 388 are inserted into the guide slits formed in the side frame 390 in the vertical direction (Uz direction), respectively, and are guided.

As shown in FIG. 7, the maximum vertical displacement of the second adjustment plate 380 is a-b.
