| 摘要 |
A sheet carrier apparatus of the present invention includes a first and a second rotary roller member, at least one of them having a rotary driving force. The second rotary roller member is constructed so as to be able to rotate around the first rotary roller member while it is being driven by the first rotary roller member. In order to control these rollers, the sheet carrier apparatus includes a control device for selectively setting the direction in which a sheet is moved from among a plurality of directions by controlling the rotary driving of the rotary roller members while carrying a sheet and by controlling the degree of angular displacement causing the second rotary roller member to rotate around the first rotary roller member while a sheet is grasped between them.
