ABSTRACT:
An eraser of the present invention comprises a magazine having set therein a carriage means for mounting a freely turning first reel loaded with an erasing ink transfer tape and a second reel for winding up the used erasing ink transfer tape and a head for bending or curving the erasing ink transfer tape before it is wound up by the second reel wherein at least the bent or curved portion of the tape is projecting with respect to the magazine. The known defects of the conventional erasing ink, such as requiring a relatively long waiting time before rewriting, difficulty of rewriting due to brush unevenness and inconvenience caused by drying and solidifying of erasing ink as well as the fatal defect of the conventional eraser of transfer type that it is usable only for typewriter, is eliminated with present invention. The invention provides a handy eraser that is quite easy to use.
