Electric-component supplying unit

An electric component supplying unit for feeding an electric-component tape which includes a carrier tape and holds a plurality of electric components at a predetermined pitch in a lengthwise direction of the carrier tape, and supplying the electric components, one by one, from the electric-component tape, the supplying unit comprising:

• a frame including a tape-guide portion which guides the electric-component tape;
• a feeding device which feeds, in said lengthwise direction, the electric-component tape being guided by the tape-guide portion, and positions the electric components, one by one, at a component-supply position;
• and
• the frame comprising a main frame member, and at least one tape-guide member which is detachably attached to the main frame member and provides the tape-guide portion,
• wherein said at least one tape-guide member comprises a plurality of sorts of tape-guide members corresponding to a plurality of sorts of electric-component tapes having different widths, respectively, each one of said plurality of sorts of tape-guide members being selectively attached to the main frame member to provide the tape-guide portion which guides a corresponding one of said plurality of sorts of electric-component tapes that has a corresponding one of said different widths.
