Abstract
A roll holder device is for use with a recording paper roll including a tubular spool shaft and continuous recording paper wound about the tubular spool shaft in a roll form. In the roll holder device, first and second holder cores are inserted in respectively first and second ends of the tubular spool shaft. A holder frame supports the first and second holder cores in a rotatable manner. Anti-dropping levers prevent the tubular spool shaft from dropping from the first and second holder cores by pushing a shaft inner surface of the tubular spool shaft.
