PROBLEM TO BE SOLVED: To eliminate necessity for detaching accessory equipment at the time of opening-closing, without expanding an occupied area by providing a control means wherein when opened under a state of accessory equipment equipped to an opening-closing component, its angle for opening-closing is controlled, and when opened under a state of the accessory equipment non equipped thereto, the angle is not controlled. SOLUTION: When an image read part 18 is equipped to an opening-closing component 17, a second arm component 2 is pushed down with a leg part 18b, and its tip engaging part 28a enters a slide part 27a of a first arm component 27. When the component 17 is opened under this state, the engaging part 28a is engaged with the slide part 27a, the component 17 is not opened by at least a state in which the first arm component 27 and the second arm component 28 are stretched in a straight line state, and the angle for opening-closing is controlled. Then, when an image read part 18 is detached, pushing pressure on the second arm component 28 with the leg part 18b is gone, the engaging part 28a is detached from the slide part 27a to release an engaged state, and the component 17 is not controlled for a pivot angle, and can be largely opened so as to come in contact with a floor face. |
