PURPOSE:To obtain the mechanism which located the disc easily with a high precision with a simple constitution, by making frictional coefficients of rollers of the carrying mechanism, where one of a pair of rollers holding the disc is driven, different from each other. CONSTITUTION:The outside circumference of disc 50 is allowed into contact with projections 39a and 39b and so on provided on the carrying path of disc 50 to locate the center hole of disc 50. Disc carrying mechanism 3 of the autoloading player having this structure is so constituted that one of a pair of rollers 23a-23c and rollers 30a and 30b holding disc 50 is driven. Frictional coefficients of both rollers are made different from each other. For example, the frictional coefficient of inverted rollers 30a and 30b is set to a value lower than that of driving rollers 23a- 23c, and further, inverted rollers 30a and 30b are rotated independently of each other. |
