Japanese Patent JP3181805

B2

PURPOSE: To reduce the restriction of the degree of freedom in terms of design and easily detach an optical scanner unit from a device by attaching the unit in a hung manner to an attachment part provided on the upper part of the optical scanner unit.
CONSTITUTION: The optical scanner unit A is provided with the attachment parts 25 for which female screw parts 25a are formed at three parts, deformed holes for which a round hole part and a circular-arcuate hole part whose center is a reference hole are connected are provided on the positions of the parts corresponding to the attachment parts 25 on the side of an optical unit attachment plate 24 and the optical scanner unit A is attached to the attachment plate 24 at the circular-arcuate hole parts of the deformed holes by attachment machine screws 40. Then, as the attachment machine screw 40 is loosened, a positioning pin fitted to the reference hole 30 of the attachment plate 24 falls off first, the head part 41 of the attachment machine screw 40 is locked to the circular-arcuate hole part and the scanner unit A is turned to the state of being hung to the lower part of the attachment plate 24 by an E ring 45 mounted to the attachment machine screw 40. In the state, the unit A is horizontally moved and the head part 41 of the attachment machine screw 40 is withdrawn from the deformed hole.
