Abstract
An ink switching cam () is rotated interlockingly with forward/reverse rotation of a head driving motor at all times to swing a cassette support member (). Accordingly, ink belts can be switched with a simple construction without using a solenoid or the like. By setting a movable area of the ink switching cam () to be within one rotation, the operations of a print head () and the ink switching cam () which are interlocked with the forward/reverse rotation of the head driving motor can be simply associated with each other.
