DE1786405B2 - ADJUSTMENT DEVICE FOR A TYPE CARRIER TRAINED AS A ROTATING BODY IN TYPING OR SIMILAR MACHINES - Google Patents

Description

The invention relates to an adjusting device for a type carrier designed as a rotary body in typewriters or similar machines, whose surface is arranged in several rows and columns Characters can be set by a rotary movement and a pivoting movement and the be printed by a print movement of the type carrier in the direction of the platen, whereby several adjustment members act on the type carrier.

With such type carriers, which are used to set a certain type of rotary movements in different Levels have to run is an articulated connection to the usually designed as a summing gear Adjustment links required. This articulation is intended to perform the two at the same time allow various adjustment movements of the type carrier in order to achieve short adjustment times. The printing movement of the type carrier from its rest position to the printing position on the platen must not have a disruptive influence on the setting positions caused by relative movements of the individual transmission links can arise.

In order to achieve the stated condition, it is known to use a carrier which carries a hollow support tube in which a tilting shaft and a rotating shaft are coaxially supported, the drive connections to the print head being housed inside the same, an advantageous further development of this Device mv setting of a spherical type head (German patent specification 1063 612) consists in the fact that the drive connection for the rotation of the print head consists of a rotating body rotatably mounted in the inclination block and releasably connected to the print head and an articulated connection between the rotating shaft and rotating body.

stands. The parts for rotating and tilting the type head are inside the arranged hollow type carrier and thereby increase its mass with each impression movement have to be accelerated and braked several times. In addition, the dimensioning of the joint parts spatially limited by the size of the type head. This allows the printing speed ability only hold in such a size as the joint parts are able to accelerate and To transmit deceleration forces.

The invention is based on the object of cim. To create an articulated connection that allows a setting and Abdruckbewegungun ^ a Typentiägers at high Write speeds. For this purpose, the mass of the moving type carrier must be kept small and the articulation will be housed at a point on the typewriter where none There are spatial restrictions for the dimensioning of the joints, for example in Inside a hollow type carrier is the case. By reducing the moving with the type head Parts is said to be the prerequisite for an increase in typing speed compared to that of typewriters usual speeds can be achieved.

This object is achieved according to the invention in that any one in the print position Character the joint of an adjusting member for rotating the type carrier and the joint of a one-actuator for swiveling the type carrier on fixed guide rods with the help of bores the adjustment members mounted pivot pins are mounted longitudinally movable and in a through the Pivot center and the stop axis are formed plane, the lever guide of an angle lever is movable with a bearing bridge.

A particularly advantageous embodiment of the invention, according to which the relative movements of the Adjusting elements of the type carrier from the rest position

the same in the print position on the platen to a minimum, is seen in the fact that the Stop axis in the middle between the outermost adjustment positions of the pivot pin mounted on the adjustment member and the ball pin mounted on the adjustment member.

In order to achieve a high degree of accuracy in the joints in such a design of a hinge connection, it is expedient to arrange a guide as far as possible in the plane of movement of the adjusting members. This is achieved in a simple manner without any particular disadvantages in that a hinge pin rotatably mounted in the summing lever is mounted so as to be longitudinally movable on a fixed guide rod.
An embodiment of the invention is in
