<p>PURPOSE: To correctly insert the cassettes belonging to the system into all the cassette devices belonging to the system by forming a 1st contour part over a 1st length on a 1st crossing wall, forming a 2nd contour part over a 2nd length on a 2nd crossing wall and extending the 1st and 2nd contour parts at least into a 1st lengthwise direction wall. CONSTITUTION: On the 1st crossing wall 13, the 1st contour part 21 in a form of a groove 25 is formed over the 1st length 17, and on the 2nd crossing wall 15 the 2nd contour part 23 in a form of a groove 27 is formed over the 2nd length 19. When a mirror image of the 1st contour part 21 is formed in a 1st plane parallel to the crossing wall and including the center 31 of the cassette and subsequently in a 2nd plane 33 parallel to a main wall and including the center 31 of the cassette, this mirror image of the 1st contour part 21 coincides with the 2nd contour part 23. Moreover, when the mirror image of the 1st contour part 21 is formed in the 2nd plane 33, the mirror image of the 1st contour part 21 is not analogous to the 2nd contour part 23. Consequently, the cassette belonging to the system can be inserted into all of the cassette devices belonging to the system.</p> |
