Printing apparatus

A printing apparatus includes a roll-out motor that rotates a roll body supported by a roll body support unit (16), a feed roller pair (23) that transports a paper (P) drawn from the roll body (RB), and a load measuring unit (42) that measures a rotation load of the roll body (RB)when the roll body...

More Information
Summary:A printing apparatus includes a roll-out motor that rotates a roll body supported by a roll body support unit (16), a feed roller pair (23) that transports a paper (P) drawn from the roll body (RB), and a load measuring unit (42) that measures a rotation load of the roll body (RB)when the roll body (RB)is rotated at a low speed and a rotation load of the roll body (RB) hen the roll body is rotated at a high speed. A rotation angle range in which the roll body (RB) is rotated at the high speed is greater than a rotation angle range in which the roll body (RB)is rotated at the low speed. In one rotation of the roll body (RB), at least a part of the rotation angle range of the roll body rotated at the low speed overlaps with the rotation angle range of the roll body rotated at the high speed.
