ABSTRACT:
A recording apparatus includes a roll of recording paper, a roll conveying roller for feeding a roll of recording paper, and a sheet conveying roller for feeding sheets of recording paper. Power from a DC motor is transmitted to both rollers through a switching mechanism. The switching mechanism includes a system gear, a planetary gear, and a planetary gear arm, and a locking member for fixing the planetary gear arm at a prescribed position. A head release cam, a head release pulley, and a timing belt cooperate with the switching mechanism to remove pressure from a print recording head to prevent damage to the head during switching. Accordingly, a roll of recording paper and sheets of recording paper can be selected and used as needed without increasing the manufacturing cost and size of the apparatus.
