PURPOSE:To attain miniaturization of a box by forming a magnetic pole tooth of a stator to an inner side wall of the box opposite to a reading face of a floppy disc so as to constitute a linear pulse motor thereby decreasing the depth of the box. CONSTITUTION:The stator 2 is fixed to a position opposite to a face of a read window 10 of a floppy disc cover 9 of a floppy disc 8 to be loaded incorporated with the box 7, and the magnetic pole teeth 6... are projected as a projected shape. Then the magnetic pole teeth 6... are buried in the box 7 as required and its upper end face is formed with the same face with the inner face wall. Then carrier magnetic pole teeth 5- I, 5-II, 5-III, 5-IV are provided corresponding to the stator magnetic pole 6... to constitute a linear pulse motor. Thus, the depth of the box is decreased and the miniaturization of the box is realized easily. |
