<p>PURPOSE:To easily switch and use one member as a dust-protective cover for a keyboard and a reading table where materials are placed while the member is mounted on a device by rotating a cover body around a vertical or horizontal shaft. CONSTITUTION:When the device is not in use, the cover body 20 is positioned over the keyboard A almost horizontally with its material setting surface down and then the cover body 20 covers the entire surface of the keyboard A and is used as the dust-protective cover. Then, the cover body 20 is rotated lengthwise around the shaft part of a fixing screw 19 by a specific angle. Consequently, the material setting surface of the cover body 20 is turned over to face up. The cover body 20 is rotated around the vertical shaft by a proper angle to face an operator, and consequently while the keyboard A becomes able to be used, the cover body 20 is set so that it is usable as the reading table.</p> |
