Abstract
A medium storing and advancing apparatus is provided which prevents, when a medium sandwiched between two tapes is wound on a drum to be stored, that the medium could not be wound due to the thickness of the tapes wound previously on the drum. The medium storing and advancing apparatus includes reels which supply and wind up the tapes, and a drum which winds up the tapes, wherein the drum is provided with a drum groove portion over the circumferentially entire periphery substantially in a middle way of the outer peripheral surface of the drum so that the tapes are wound in the drum groove portion.
Claims7
A medium storing and advancing apparatus comprising reels which supply or wind up tapes, and a drum which winds up the tapes supplied from said reels, said apparatus storing a medium by holding the medium between the tapes being wound up by said drum, or drawing out the medium held between the tapes by winding up the tapes by said reels to unwind the tapes from said drum, wherein
- said drum is provided with a groove portion over a circumferentially entire periphery substantially in a middle way in an axial direction of said drum so that the tapes are wound in said groove portion.
A medium storing and advancing apparatus comprising tapes, reels on which one end portions of said tapes are wound, and a drum on which other end portions of said tapes are wound, said apparatus storing a medium by winding up said tapes by said drum to wind up the medium together with said tapes, or drawing out the medium wound up by said drum by winding up said tapes by said reels, wherein
- said drum has a groove portion over a circumferentially entire periphery substantially in a middle way in an axial direction of an outer periphery surface thereof so that said tapes are wound in said groove portion.
