PURPOSE:To avoid the door from being stood in the way when the door is opened, by fitting the guide roller having almost elliptical shape and cylindrical projection at both sides of the door and taking the guide groove guiding the guide roller as long and circular grooves. CONSTITUTION:The door 1 is formed almost the same size as the concave step of the front panel, the L-shaped hinge 2 is fixed at both lower end sides of the door 1, the guide pin 2a is projected at the lower end of the internal corner, and the projected shaft 2 is projected at the upper end of the external corner. The shaft 3a the projected shaft 2b of which is inserted is placed at the tip of the linking plate 3, and the bearing 3b to which the gear shaft is inserted is formed at the rear end. The guide roller 4 is fitted at the tip of the projected shaft 2b, and the tip which is formed almost in elliptical shape has the cylindrical projection. That is, since the part of the guide roller shaped in almost ellipse form is formed in semicircular shape at the front and rear edge and the upper and lower edges are formed in circular arc shape more or less, the door can be contained in the main body after the door is open, and it can be avoided from being stood in the way. |
