摘要
A disc operated selector chart for promoting a product range has a disc (2) with concentric data spaced around the disc and mounted on a pivot (5) inside a wallet (30. The wallet has four windows; two large and two small. The large windows define the range for each product and the small, windows the available type numbers. The user turns the disc to align a marking against a set parameter, e.g. required dimension, and reads the product type number in the adjacent small window. The two selector ranges can be, for instance, product size and product finish. The wallet is completed by a hinged front cover (6) with a retainer (7) on the inside for loose leaf product information.
