Disclosed is a bobbin fixing apparatus. The bobbin fixing apparatus includes a rotating shaft installed to a mounting plate and provided with a fixing unit partially protruding from the rotating shaft so as to be inserted into the rotating shaft, and a bobbin on or from which an object is wound or unwound, the bobbin being placed on the rotating shaft such that the fixing unit is exposed in front of the bobbin. The bobbin includes a rotating body, a plurality of bobbin members on which an object is wound, and an end coupler configured to be operated upon receiving pressure when the bobbin is placed on the rotating shaft, the end coupling serving to keep an end of the object in a fixed position on the rotating shaft during winding or to release the end of the object from the fixed position during unwinding.
