PURPOSE:To easily attach or detach an ink sheet cassette by transmitting the movement of the outer end face of a rotary member to driving and movable shafts by a cam unit, cooperating both the shafts with the axially central movement, and providing bushes secured to the inner ends of both of the shafts detachably to an ink sheet bobbin. CONSTITUTION:When an operating lever 14 is manually rotated, rotary members 22, 23 are simultaneously rotated in the same state through a connecting lever 28, a cam unit 36 thus relatively displaces, and a driving shaft 20 and a movable shaft 21 move against a spring 29 in a direction of an arrow. As a result, the bushes 24, 25 are also pulled out to isolate ink sheet bobbins 31, 32 from the bushes 24, 25, and an ink sheet cassette 2 can be straightly pulled out freely. The cassette 2 may be mounted in the reverse order to the above procedure. |
