Abstract

An electronic checkbook (10) is provided for printing checks. electronic checkbook (10) is of a hand-held size and operates on two AAA batteries. An on/off switch (30) which includes a needle valve (410) controls ink flow. A print cap switch (26) is also provided for rugged applications. Checks are advanced under a printhead (38). The printhead (38) and a roller shaft (46) for advancing the checks are both driven by a single motor (56). A transmission (54) translates power from the motor (56) to the printhead (38) and the roller shaft (46). The position of both the motor (56) and the printhead (38) are sensed by use of a single LED (124) and photodetector (128). Ink is supplied to the printhead (38) from an ink cartridge (12). Data is stored in a non-volatile check register (16). Reconciliation of transactional information can be made by reference to information stored on a statement strip (20).
