Abstract (en)
A spool (36) for thermal print roll paper enables detection of a recording characteristic and/or the amount of roll paper remaining thereon by means of a detecting device (45, 46) provided on a printer body and prevents erroneous loading of roll paper. The spool (36) has a detecting portion (40a) and/or an engaging portion (38, 39) formed in an integral relationship at the ends thereof so that the end portion thereof may have a function of identifying a recording characteristic or a remaining amount of print roll paper on the spool or of preventing erroneous loading of roll paper. The spool (36) can be made of a synthetic resin material so that the production cost thereof will not be increased significantly.
