The detecting section 30 is composed of a recessed section 30a and a projection 30b, and the width W1 of the recessed section 30a is made greater than those W2 of the grooves 31. In addition, the initial depth D1 of the recessed section 30a is made shallower than those D2 of the grooves 31 by the serviceable depths D3 of the grooves 31. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
