摘要： A toy simulating a calculator having a visual display read-out by providing a housing having a display window with a continuous loop of strip material viewable therein, the strip having a plurality of stations with indicia thereon, the stations being preselectable by a child using the toy. A keyboard is provided, the keyboard having an actuating key and a plurality of indicating keys, each of the indicating keys having indicia thereon corresponding to a predetermined one of the stations. The mechanism includes a spring-biased disc having a plurality of projections thereon for coacting with a depressed indicating key, the mechanism being operated by a pull string which removes the stations from view, the strip then being moved under force of the spring upon sequential activation of an indicating key and the actuating key to permit the preselected one of the stations to appear at a predetermined location in a display window.
