A paper ejecting device for ejecting a recording cut sheet cut of a recording apparatus is disclosed. The paper ejecting device includes an ejector for ejecting the recording cut sheet through an outlet which is provided at a portion of the recording apparatus, a tray disposed adjacent to the ejector for receiving and recording cut sheet which has been ejected through the outlet by the ejector, and a sheet reversing member operable between a first position for guiding and reversing the recording cut sheet ejected through the outlet before the sheet falls onto the tray, and a second position for permitting the recording cut sheet ejected through the outlet to be received on the tray, without a reversal of the cut sheet.

A paper feeding apparatus for the printer having an intermittent mechanism between a driving motor and both a paper feed roller and a platen. The intermittent mechanism allows both the platen and the paper feed roller to rotate simultaneously and also allows only the platen to rotate while the paper feed roller is suspended, so that a sheet of printing paper is set straight along the platen. When the rotational direction of the driving motor is reversed to reverse that of the platen, the driving motor stops rotating for a limited period. Under such conditions the sheet is fed properly in response to the rotation of the platen, being free from the inertia force of the sheet and from the platen's vibration.

Paper feeding apparatus for printer

An electronic typewriter comprising: a keyboard having a plurality of keys and generating an encoded signal in response to the depression of each key; a printing unit having a print wheel with a plurality of type elements disposed around the periphery thereof, a step motor for rotating the print wheel, a print hammer for impacting the type element brought to a printing position, an ink ribbon, and a ribbon drive mechanism for bringing the ink ribbon to the printing position; and an electronic control circuit for coupling the keyboard to the printing unit. The electronic control circuit controls the rotation of the step motor according to the encoded signal received from the keyboard so as to bring a type element selected by the encoded signal to the printing position within a short time for executing quicker printing, and further controls the action of both the print hammer and the ribbon drive mechanism in response to the rotation of the step motor.

A ribbon cartridge includes a pair of housings having apertures, a pair of ribbon spools rotatably supported in the housings, and a ribbon wound on the spools. A portion of the ribbon is exposed to the outside of the housings through the apertures when the ribbon is fed from one spool to the other. Each housing rotatably supporting a hold member. The hold member has a holding portion which is movable across a ribbon passage within the respective housings for holding the ribbon and has an engaging portion which is engageable with teeth on a flange of each spool, and each hold member is biased by a spring member. When the cartridge is removed from the typewriter, the holding portion is moved across the ribbon passage and a portion of the ribbon slackened and exposed from the housing is tensioned. The engaging portion prevents the rotation of the respective spools by the biasing force of the spring member, and when the cartridge is installed in the typewriter, the hold member is retracted to a released position by a retract member of the typewriter.

Ribbon cartridge having slack preventing means

A ribbon cartridge for typewriters having a plurality of type bars which have the respective type fonts or characters at the top portions thereof and which are struck toward a printing point on a platen during the printing operation. The ribbon cartridge includes a pair of housings made of plastic material and a connecting arm member made of a metal strip for interconnecting the two housings. The connecting arm member has its center portion positioned in front of a type bar guide (on the side of the typist) and is formed substantially into a U-shaped opening as seen from the front side of the typewriter in order to permit the printing operation of the respective type bars. A spool for winding the printing ribbon is rotatably mounted in each housing, the spool being operatively connected in the usual manner to an ordinary ribbon drive means which is provided on the typewriter. Each one of the housings is provided with an aperture or slot to allow passage therethrough of the printing ribbon. A printing ribbon which is wound on one spool is fed through the aperture in its housing and taken up on the other spool through the aperture in the other housing.
