<P>PROBLEM TO BE SOLVED: To provide image observation spectacles that are put on with comfort. <P>SOLUTION: Image observation spectacles 1 comprise: an image observation part 21 for observing an image; a frame part 22 for holding the image observation part 21; a pair of temples 3 pivotally supported by the frame part 22 in such a manner that one end is rotatable; slide parts 4R and 4L arranged on the temples 3 and having protrusions 41R and 41L protruding towards a frame part 22 side; and contact surfaces 221R and 221L formed on the frame part 22 and abutting on the protrusions 41R and 41L to regulate rotation in a direction that widens the distance between the temples 3. The slide parts 4R and 4L are composed to be slidable in a first direction crossing a virtual plane along a rotation direction of the temples 3, whereas the contact surfaces 221R and 221L are inclined with respect to the first direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
