PROBLEM TO BE SOLVED: To provide a rotary drum displaying device which can accurately attach a mechanism main body to a device enclosure. SOLUTION: This rotary drum display device is constituted in such a manner that a plurality of pattern display mechanism 1 equipped with a pattern displaying body 2 which is rotate-driven by a driving source attached to a mechanism body 71 are provided in parallel in the device enclosure 92 of which the front side is opened. In the rotary drum display device, the mechanism body 71 is equipped with an attaching/detaching part (an upper front mechanism attaching part 71d and a lower front mechanism attaching part 71b) on the top and the bottom of the front side. The rotary drum display device is constituted in such a manner that the mechanism main body 71 can be independently attached/detached to/from the device enclosure 92 by the attaching/detaching part from the front opened side of the device enclosure. On the attaching/detaching part of the mechanism main body, a mechanism body side positioning/engaging part (positioning hole 71g) is provided. A device enclosure side positioning/engaging part (positioning protuberance 103) is provided at the top and the bottom on the front side of the device enclosure corresponding to the attaching/detaching part. When these positioning/engaging parts are engaged with each other, the mechanism body is attached to the device enclosure under a positioned state. COPYRIGHT: (C)2004,JPO&NCIPI
