<p>PURPOSE: To enable it to regulate each position of various sized recording mediums without adding any load by dint of spring force. CONSTITUTION: A guide plate 15 out of a pair of guide plates 14 and 15 regulating each position of recording mediums 12 is made up of being installed in a body part bottom surface 13a by way of getting its projections 17 and 17 fitted in a hole part 23 of a rotator 20. In this constitution, this rotator 20, where the hole part 23 are plurally installed in varying a distance from the turning center, is rotated and thereby the hole part 23 having the projection part 17 fitted varied to some extent, whereby each distance between these paired guide plates 14 and 15 is variously alterable.</p> |
