PROBLEM TO BE SOLVED: To provide a pattern display with a rotor, offering controlled vibration of the rotor for stable scroll display. SOLUTION: A spoke 28 of a drum 20 is formed in a plate shape with its plate width extending along the radial direction of a cylinder 26 and its plate thickness extending along the peripheral direction of the cylinder 26, so that it is elastically deformable along the peripheral direction of the cylinder 26. If vibration occurs in a stepping motor 18 and transmits to a hub 30, the spoke 28 is elastically deformed to absorb the vibration, therefore causing no vibration from the hub 30 to the cylinder 26. Consequently, there is no disorder of the scroll display of a pattern due to the vibration of the stepping motor 18. |
