Abstract

PURPOSE: To make it possible to obtain the accurate length of an optical path easily by moving the 1st reflecting means and 2nd reflecting means in accurate 1:1/2 speed proportion by a simple link mechanism.
CONSTITUTION: At both sides of frame 1, guide bars 2 parallel to original table 12 are provided and on those guide bars 2, the 1st support part 3 having the 1st mirror 13 and lamp 15 and the 2nd support part 4 supporting the 2nd mirror 14 are supported at an interval reciprocating in the lengthwise direction of bars 2. Opening- closing link 6 made of a couple of left and right link members 6a and 6b pivoted 5 mutually rotatably at each one terminal is linked to the 2nd support part 4 while its shaft support part is made oscillatory on the 2nd support part 4. As pulley 21 is rotated at circumferential speed V in the direction of arrow A, the 1st support part 3 (together with the 1st mirror 13) and 2nd support part 4 (together with the 2nd mirror 14) move at speeds V and V/2 respectively in the direction of arrow (a) to scan the original.
