<p>PURPOSE:To improve similarity and the rate of accomodation, by composing a tape of a flexible material and holding the tape in a case so as to be wound and pulled out to detect the winding and pulling-out length of the tape and the moving distance of the case. CONSTITUTION:A tongue 3a is fitted to one end of a tape 3 made of a flexible material and the tape 3 is stored in a box 4 with a slit 5 so as to be pushed and pulled out to/from the box 4. A case 7 for the tape 3 is mounted, a guide rod 11 is fitted through a through hole 9 and the case 7 is supported by the rod 11 so as to be moved in the X direction. A pulley 13 is mounted in accordance with the rod 11 and engaged with a reeling thread 17 so as to be pivotally supported by a strut 15. An X direction encoder 21 detects the moving distance of the case 7 and a Y direction encoder 19 detects the winding and pulling-out length of the tape 3. Consequently, similarity and a space factor are improved without reducing manueverability.</p> |
