Abstract
A print head (15) on a carriage (16) slides on a carriage guide bar (17) in front of a platen bar (18). A receipt slip (25) is fed from a roll (26) over part of the width of the platen bar (18) to a knife (40) for cutting off individual receipts. A daybook slip (45) is fed from a roll (46) over the bar (18) to a take-up roll (50). Other documents may be fed in for printing either downwardly between upper guides (37 and 38) or upwardly between lower guides (35 and 55). In either event the inserted document is engaged by a drive roller (60) and pressure roller (70) to be positioned at a predetermined height, under control of photodetectors (80 and 81). The pressure roller (70) is mounted between levers and can move away from the drive roller (60) to accommodate the thickness of the inserted document. The levers also support the carriage guide (17), whereby the head (15) is positioned a constant distance from the surface on which printing is effected.
