PURPOSE:To prevent the drift (oscillation) of a disk-shape substrate at the time of pushing up the disk base in an accommodating case while supporting it erectly by a substrate push-up arm and hold the pushed-up disk-shape substrate easily and positively by a substrate holding hand provided with guide rollers for holding the disk-shape substrate from four directions in conveyor mechanism for conveying the disk-shape substrate in the accommodating case erectly into the machining position of a texture device for roughening the surface of the disk base. CONSTITUTION:The supporting groove of a substrate supporting plate provided at the tip of a substrate push-up arm is inclined groove mechanism for supporting a disk-shape substrate 12 in the inclined state. Each guide roller 35 of a substrate holding hand 34 is engaged with the disk-shape substrate 12 supported being inclined by the inclined supporting groove of the substrate push-up arm, and there is provided an asymmetric guide groove 36 with one edge part formed higher so as to induce the disk-shape substrate 12 in the erected state. |
