1. A disk recording and/or reproducing apparatus comprises:
first and second front transport members for holding a disk-like recording medium in its diametrical direction during insertion;
drive means for driving said first front transport member and giving rotation force to said disk-like recording medium held
between said first and second front transport members to cause the disk-like recording medium to rotate and move in a direction
of insertion;
a space adjusting mechanism capable of making said first and second front transport members become close to or away from each
other in response to the size of said disk-like recording medium.
first and second rear transport members for holding the disk-like recording medium in its diametrical direction during insertion,
said first and second rear transport members located away from said first and second front transport members along the direction
of insertion, said first and second front transport members and said first and second rear transport members supporting four
points of the outer peripheral edge of said disk-like recording medium at a first degree of insertion;
a support lever having a pivot point at a first end and a disk holding portion at a second end, such that the disk holding
portion rotates about said pivot point, the disk holding portion and the first and second rear transport members supporting
three points of the outer peripheral edge of the said disk-like recording medium at a second degree of insertion; and
a disk selecting cam mechanism configured to control an adjustment amount of said space adjusting mechanism in response to
the size of said disk-like recording medium, wherein
said disk selecting cam mechanism includes a large diameter cam portion and a small diameter cam portion, and
a cam pin of said space adjusting mechanism is configured to be selectively inserted to and ejected from the large-diameter
cam portion or the small diameter cam portion.
