Abstract: Disclosed is a vehicle construction of an automobile provided with a slide door being used in a front door of an automobile and having an upper side front end positioned at the rear of a lower side front end, roller assemblies provided in an upper side front end, a lower side front end and an intermediate of back end portion, and guide rails for supporting the roller assemblies arranged in an upper, a lower and an intermediate portions of a car body.

Abstract: The present invention relates to a car providing a sliding door comprising guide rails mounted along an entry opening formed on the front half section of a car body and a sliding door used as a front door to be slid through a roller assembly to be engaged with each guide rail when it is opened or shut. In this car, the sliding amount of the sliding door is regulated so as to disable the rear end of the sliding door to be projected from the rear end of a car body when it is opened. And, in order to enable the entry opening opening to be fully opened, an auxiliary handle is providced in addition to an outside handle and an inside handle. Further, the invention also relates to improvement of opening or shutting mechanism and structure of the sliding door.

Abstract: The present invention relates to a structure of a lower rail for guiding a slide door and a mounting structure to a side sill. A part of the side sill is projecting externally and covers the upper part of the lower rail. The top end portion of the lower rail is bent inside the side sill and is fastened to the rail housing box and the floor side panel. The roller supporting member for supporting the roller and the arm being fastened to the door are connected by means of a pin. A groove is formed on the bottom wall of the rail housing box corresponding to the moving range of the pin, and the height of the rail housing box is reduced by letting the above-mentioned pin face inside the groove. And, both the stopper at the rear end portion of the rail and the leaf spring are formed independently each other, then the stopper is inserted into an opening of a rail and the leaf spring is assembled to the rail from above the rail so that the both may be assembled with one screw from above the rail.

Abstract: An automatic paper loading apparatus for a typewriter provided with a platen, feed rolls, and a paper bail. The paper loading apparatus essentially includes a paper alignment member pivotally mounted on a frame, a paper guide carried by a movable carriage, and three controllers, from first to third. The paper alignment member is engaged with the leading edge of an inserted printing paper while the feed rolls are spaced from the platen. The feed rolls are urged on the aligned paper and the paper alignment member is spaced from the platen for being disengaged from the leading edge of the printing paper owing to a manual operation of a lever.

Abstract: 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.

Abstract: A character selection mechanism for a typewriter having a single type head with characters arranged in rows and columns thereon, which mechanism comprises, for either row selection and column selection similarly, a series of cams, a series of cam followers, a series of transmitting members, and an output member, as one set. The cams are fixed on a cam shaft which is rotated once in response to depressing of any one key. Each of the cam followers is rotated by each corresponding cam and is shifted, against a biasing force, by each corresponding transmitting member from a first position to a second position in response to depressing of the corresponding key. The cam follower engages the output member at the second position for controlling its operation based on the rotation of the cam shaft. The output member is connected to the type head via a connecting mechanism.

Abstract: An electric typewriter having a prevention mechanism for preventing printing errors caused by a depression of a few keys in very rapid succession. The prevention mechanism includes a lock member for locking a clutch, which is interposed between a drive motor and a printing mechanism, in a disengaged condition. The lock member is normally held in a non-operational position for allowing the clutch to be engaged, and is moved in response to a special operation of a sensing member to an operational position for keeping the clutch in a disengaged condition. The sensing member is so disposed as to be moved in a distinct way different from the normal operation mode when a few keys have been depressed in very rapid succession.

Abstract: In a ribbon changing mechanism, a ribbon retaining portion of the ribbon vibrator lifts a printing ribbon from a lowered non-printing position to an elevated printing position, in response to the printing operation. When a push button is depressed for retaining an actuating lever in a first position where said ribbon vibrator is shifted to a ribbon changing position, the ribbon vibrator connected to the actuating lever is moved upward from the lowered non-printing position to the ribbon changing position, independently of the printing operation and retained in the ribbon changing position. The ribbon retaining portion is comprised of a rear ribbon retaining member and a front ribbon retaining member, which defines a pair of ribbon passages having closed top and bottom portions in combination with both ribbon retaining members.

Abstract: 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.

Abstract: 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.
