摘要： The line spacing device comprises an electric motor 26 arranged to rotate selectively in a clockwise direction and anticlockwise direction a control disc 21 carrying a pawl 31 on an eccentric 29. The tooth 32 of the pawl describes a closed trajectory engaging in the teeth of the wheel 14 and of a sense the same as the rotation of the disc 21, whereby the paper support platen 12 is rotated by one increment in the opposite sense. A central control unit controls the clockwise and anticlockwise rotations of the electric motor. A cam 28 disengages a detent pin 16 from the wheel 14 so that the motor is only lightly loaded when actuating the platen.

摘要： A cartridge 47 for a typing ribbon 48 and spools for a correcting ribbon 52 are mounted on a common frame which can tilt about a spindle 46. In a lowered position of the frame the typing line behind a daisy wheel 28 is visible. The frame is raised by a first stroke to the position shown to dispose the typing ribbon 48 over the typing point on the platen 11. A longer stroke raises the correcting ribbon 52 to the typing point and this longer stroke also actuates an automatic ratchet wheel and pawl type of feed mechanism for the correcting ribbon. The two strokes of the frame are controlled by a disc comprising two cam tracks with a common part 83 and separate parts 84 and 86 having different degrees of eccentricity relative to the common part. The grooved cam tracks are so shaped that a follower pin 87 on an arm 88 depending from the frame enters the radially inner track 84 when the disc 71 is rotated clockwise by a reversible electric motor, thereby to raise the frame by the smaller amount, whereas it enters the radially outer track 86 in the case of anticlockwise rotation. The disc 71 also carries a frontal cam which operates a ribbon feed mechanism fort the ribbon in the container 47.

摘要： A print head (15) on a carriage (16) slides on a 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.
