PURPOSE:To make it possible to record and reproduce information accurately without erroneous input of information by providing a guide material, which guides a recording medium along a fixed locus, and elastic material parallel with the material above, and an axis material, etc., to cause the recording medium to advance along the fixed locus. CONSTITUTION:Metallic roller rim 2 uniting with feeding roller axis 1 is a conical trapezoid. Soft rubber roller 3 is printed on rim 2. Magnetic card 4 of a recording medium is pressed by roller 3 and is fed in guide groove 6 by the contact frictional force. Guide groove walls 5 are in both sides of guide groove 6, and one of them is a reference face (5' is a reference face in the figure). Recording and reproducing are performed by magnetic head 8, and they are performed accurately without generation of track slippage of magnetic card 4. Further, the constitution is easy to produce and assemble. |
