  • the lever 412b raised by the cam member 412a can be pressed downward.
  • the lever 412b can be lifted by a force slightly larger than the elastic force of the elastic member 412f, so that it can be easily replaced with a cam member having a different size.
  • the cam member 412a and the drive motor 412c include four coupling protrusions g1, g2, g3, g4 and four coupling grooves (not shown). Since it is coupled by the axial coupling portion (412g), it is possible to accurately maintain the rotation center of the center hole (C3) and the drive motor (412c) of the mating surface of the cam member (412a), the cam member (412a) and the drive motor ( It is possible to prevent the 412c from being misused with each other, and to evenly distribute the stress applied to the engagement surface of the cam member 412a by the rotational force to increase the life of the product.
  • the tilting shaft 411 whose position is changed by the position variable unit 420 and the tray 300 whose initial position is set by the position setting unit 500 are fixed to each other. Since the government part 413 is provided, the tray 300 can be tilted while the position of the variable tilting shaft 411 is accurately fixed to the tray 300 before the tray 300 is tilted.
  • the inner diameter of the fixing hole 413c gradually becomes wider toward the fixing protrusion 413b, and the outer diameter thereof gradually increases so that the fixing protrusion 413b corresponds to the fixing hole 413c. Since the shape becomes smaller, interference between the fixing hole 413c and the fixing protrusion 413b may be minimized when the tray 300 is tilted, thereby preventing abnormal vibration of the device that may be generated through the interference. Furthermore, since the outer diameter of the distal end of the fixing protrusion 413b is smaller than the inner diameter of the tip of the fixing hole 413c, the interference with the fixing hole 413c is minimized while the fixing protrusion 413b is inserted into the fixing hole 413c.
