Abstract
A control panel for a microfiche reader includes an alphabetic keyboard having a plurality of buttons arranged in parallel rows and a numeric keyboard carrying numeral index images. Each row of the buttons is provided with an index carrier carrying a plurality of indicia. Each of this indicia corresponds to a row of images extending along one of the coordinate axes. These index carriers are switched to a plurality of positions to thereby align the respective indicia with the associated button which is pushed to locate the row of images in which the individual image to be retrieved is located. The second keyboard is thereafter used to locate the individual image in the row of images found by the first keyboard.
