摘要： In a printer, a sheet discharge port for discharging a sheet therefrom is provided on the upper surface of an exterior case, and a recess portion for preventing invasion of a foreign material into the sheet discharge port is formed in the neighborhood of the sheet discharge port. The recess portion passes by the sheet discharge port, and at least one of the ends thereof is opened to the side surface of the exterior case. The side surface of the exterior case to which the open end of the recess portion is adjacent forms a foreign material discharging passage along which a foreign material discharged from the open end of the recess portion falls down without invading the printer.

摘要： An ink switching cam (40) is rotated interlockingly with forward/reverse rotation of a head driving motor at all times to swing a cassette support member (20). Accordingly, ink belts can be switched with a simple construction without using a solenoid or the like. By setting a movable area of the ink switching cam (40) to be within one rotation, the operations of a print head (10) and the ink switching cam (40) which are interlocked with the forward/reverse rotation of the head driving motor can be simply associated with each other.

摘要： A cutter device includes, in addition to one solenoid 17, two pairs of assemblies disposed in parallel with each other in a direction of movement of a cutter 2, the first pair having a rack 5, a pinion 10, and a clutch 49 to control rotation of the pinion, and the second pair having another rack 6, another pinion 11, and another clutch 50 to control rotation of the pinion. In partial-cutting operation, the cutter 2 is moved by engaging the rack 5 in the first pair with the pinion 10 in the first pair rotated through power from the clutch 49 in the first pair. In full-cutting operation, the cutter 2 is moved by engaging the pinions 10,11 in the first and second pairs concurrently rotated through power from the clutches 49,50 in the first and second pairs with the racks 5,6 in the first and second pairs. The pinion 10 in the first pair causes the full-cutting first half movement of the cutter, and the pinion 11 in the second pair causes the full-cutting latter half movement thereof.

摘要： In a dot impact printer, printing heads impact on an inked ribbon so as to form a pattern of dots on a paper sheet. The more often printing is carried out, the looser the central portion of the inked ribbon becomes. A sensor disposed perpendicularly against a surface of the inked ribbon detects such a condition of the inked ribbon, emitting a signal. Receiving the signal, a control means finds the inked ribbon unusable, interrupting the printing operation, and knowing a timing to replace the inked ribbon. The control means operates an alarm to urge replacement of the inked ribbon. Therefore, the dot impact printer is prevented from performing the printing operation under unfavorable conditions.

摘要： A push-pull printer includes at least one tractor unit thus is formed to have both a pull function and a push function. Fork-like mounting portions are respectively formed at lower portions of a pair of frames provided at both ends of the tractor unit. A pair of tractor guides are located at each of push and pull feed positions of the printer body. Each guide detachably holds a corresponding fork-like mounting portion. When the tractor is to be used in the push type paper feed mode, the fork-like mounting portions are attached to the tractor guides located at the push feed position. However, for use in the pull type paper feed mode, the fork-like mounting portions are attached to the tractor guides located at the pull feed position. Two such tractors, one providing the pull function and the other the push function, can be used cooperatively.

摘要： A paper feed apparatus includes a plurality of guide ribs formed on a printer top cover disposed above a platen, the guide ribs being aligned along the axial direction of the platen, and a discharge roller is arranged between each pair of the guide ribs. Each discharge roller has its outer peripheral surface slightly extending toward corresponding guide ribs with respect to guide surfaces of these ribs and cooperating with the ribs to hold the printing paper. When the discharge rollers are driven in synchronism with rotation of the platen, the printing sheets are fed at a speed slightly higher than the paper feed speed of the platen. Therefore, the plurality of printing sheets can be simultaneously fed without causing a deviation therebetween.
