A printer includes a printing portion configured to print on a print medium, a ribbon supply shaft configured to hold an ink ribbon to be supplied to the printing portion, a ribbon roll up shaft configured to roll up the used ink ribbon, a printing unit provided swingably, the printing unit having a thermal head that constitutes the printing portion, and a partition member swingably provided in the printing unit, the partition member partitioning the ink ribbon and the print medium, and the ribbon supply shaft is provided in the partition member.

A conveying device includes a controller configured to control conveyance of a workpiece. The controller includes a first calculator configured to calculate a first roll estimated radius of a first roll varied as a first support shaft rotates. The controller further includes a second calculator configured to calculate a second roll estimated radius of a second roll varied as a second support shaft rotates. The controller also includes a first support shaft drive controller configured to cause a first support shaft driving motor to rotary drive at a first angular velocity according to the first roll estimated radius. The controller further includes a second support shaft drive controller configured to cause a second support shaft driving motor to rotary drive at a second angular velocity according to the second roll estimated radius.

Provided is a medicine packaging device. The medicine packaging device includes: a reader-writer that reads information from an IC tag installed at a supply core of an ink ribbon roll detachably installed to an ink ribbon cassette as well as writes information to the IC tag; a motor control unit that controls a winding motor for rotating a winding core, based on a used length of the ink ribbon which is information read from the IC tag, so that the ink ribbon of the ink ribbon roll runs in a winding direction at a higher speed than a feeding speed of a continuous sheet for packaging; and a written information output unit that outputs information showing the used length of the ink ribbon which has been changed due to use of the ink ribbon, to the reader/writer as information written on the IC tag.
