<p><P>PROBLEM TO BE SOLVED: To provide a rotary drum display device capable of easily winding a pattern display body around wheels in a regular state, stably rotating the pattern display body, and preventing damage to the pattern display body. <P>SOLUTION: This rotary drum display device rotates the pattern display body by winding the endless belt-like pattern display body around a driving wheel and a driven wheel 21 and driving the driving wheel by a motor. In the rotary drum display device, the quantity of movement in the direction parallel to the rotation axis (a bearing part 27) of the driven wheel 21 is larger than the quantity of movement in the direction parallel to the rotation axis of the driving wheel. The driving wheel is fixed/attached in the direction parallel to the rotation axis of the driving wheel, and the driven wheel 21 is attached movably in the direction parallel to the rotation axis of the driven wheel 21. The driven wheel 21 is structured to be moved according to the rotation of the pattern display body by the driving wheel. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
