Device for making it possible more easily to input instructions relating to a given program into a small calculator which is programmable but not plug-in. The invention relates to a system making it possible to avoid having to look back and forward between the listing and the keyboard of the calculator during inputting of the program. The principle in itself consists in unwinding a pre-prepared program strip above the keyboard of the calculator, a mirror 8 which is both reflecting and transparent allowing the program strip to be juxtaposed with the keys of the calculator. The device consists of a drive assembly 11, a movable mirror 8 which can be oriented by virtue of an articulated arm 9, a base reserved for installing the contactor 3 adjacent to the calculator housing 2. This device is mainly intended to facilitate and to encourage use of small calculators which are programmable but not plug-in. IMAGE
