In a rolled object holdiing apparatus whose holding members hold both ends of a roll core, a roll core releasing device comprises a core pushing mechanism which in turn consists of a core pushing member and a driving means for moving the core pushing member at least in the direction of radius of the core. The core pushing mechanism is either installed in a core receiving member or in a core holding member. Whether to operate the driving means for the core pushing member is controlled by a core detector in the core receiving member. With this construction, the core releasing device of the invention performs automatic and reliable releasing of the core from holding members of the rolled object holding apparatus, thus eliminating various problems experienced with conventional devices during automatic replacement of rolled objects.
