Description

() WRITTEN MACHINE WITH LEVER-SEGMENTAL LIQUID CARRIER

one

The invention relates to the printing industry, in particular to writing and similar mechanisms.

A known typewriter with a lever-segment letter carrier, containing a binder and a plate spring rigidly mounted on the binder, for interacting with the letter carrier lj.

However, this device does not have the means to control the impact force, which reduces print quality.

The aim of the invention is to improve the printing quality of a typewriter.

The goal is achieved by the fact that a typewriter with a lever-segmented letter carrier, containing a book binder and a plate spring rigidly mounted on the book binder, to interact with the letter carrier, has a litter force regulator movably mounted on the book binder. and the leaf spring has a longitudinal groove for moving the regulator therein.

FIG. 1 shows the device when the letting lever is in the printing position, general view; in fig. 2-, the same, when the lettered lever is in the intermediate position, axrometer.

The writing machine with a lever-segment letter carrier includes lettered levers 1, which are installed rotatably with the help of a common arcuate axis 2 on a segment, 3. One end of the lettered levers 1 is connected with gami + to keyboard levers (not shown), and the other end is padded 5 with letters, 6. In addition, a fixing bit 7 and a protrusion 8 are made on each lettered lever. portions of the segment 3 are located the letter-9 and the plate spring 10, which are jointly fixed to the surface of the segment 3- the book-leader 9 has a groove 11 that passes into two L-shaped guides 12, and a supporting surface 13- LettersWoman is positioned so that the groove 11 and guides 12 provide for the installation of the bit 7 and correspondingly, the letter pad 5 in the print area of the sign on the information carrier Ik located on the support roller 15. In this case, the angle of rotation of the letting lever 1 towards the supporting roller 15 is limited by the supporting surface 13. In the center of the bicon9 the longitudinal groove 16 is made, and the plate spring 10 is a groove 17 coaxial to it. The longitudinal groove 16 has several fixedly fixed landing adjusters from the impact bump 18, having a head 19 and a flange 20, which couple the plate spring to the letter truncator 9 ora 20 are flats 21 to ensure movement of the regulator in a narrow groove portion of figure 16 and the head 19 on the end of the corrugated surface 22, which has only grooves parallel corrugations. In this case, the direction of grooves of the grooves is perpendicular to the direction of the faces 21. This allows visual control of the installation of the impact force regulator. The device works as follows. When pressing the key of the typewriter, the lettered lever 1 rotates on axis 2 and moves towards the windrower 9 and further to the printing zone. Bookrunner 9 (Accepts guide 12 lettered lever 1, thereby excluding the possibility of an arbitrary deviation of the point of the letter 6 in the printing step. With further movement, the letting lever 1 enters the free flight zone at which the lettered lever controls not the kinematic chain from the key, but regardless of it, under the action of acquired kinetic & energy, therefore, the intensity of staining of the impression, i.e. the quality of the print, is determined mainly by the magnitude of this kinematic energy. The loose beard 7 of the lettered lever 1 comes into contact with the leaf spring I) and, overcoming its resistance, impresses the sign on the information carrier 14. The amount of kinetic energy of the lettered lever 1 depends on the stiffness of this spring. Therefore, to achieve the desired print quality, the operator, before starting work, installs an impact force regulator18. For this, the impact force regulator is rotated beyond the corrugated surface 22, oriented in the direction of the grooves of the grooves, to their vertical position. Here, the flats 21 are set parallel to the axis of the figure groove 16 and the impact force regulator 18 moves to one of the fixed positions. The installation of the adjuster 18 provides movement and the flange 20, which changes the working length of the leaf spring 10. Thus, the stiffness of the leaf spring changes. After the impact force regulator is installed at a predetermined position, the operator fixes it in such a way that the flat face 21 is perpendicular to the axis of the longitudinal groove 16 and the possibility of spontaneous adjustment is excluded. Thus, by setting the impact force regulator 18 to one of the fixed positions, the kinetic energy of the letting lever 1 is adjusted when the optic, a mark, is applied to the information carrier 14, i.e. the intensity of staining of the mark imprint increases or decreases. After the imprint, mark, is placed on the information carrier 14, the protrusion § abuts against the bearing surface 13 and finishes the working movement of the lettered lever 1, which begins to move to its original position under the action of a return spring (not shown). In this case, the cocked spring 10 also tends to return to its original position. And it acts on the lettered lever 1, together with it additional energy. Consequently, the use of this device allows one to achieve high print quality by obtaining, equal-coloring prints and speeds up the process of returning the lettered levers to the initial position, i.e. increases print speed. The invention of the typewriter with a lever-segmented letter carrier, containing a book-carrier and a plate spring rigidly mounted on the book-driver for interaction with the type-bearer, which, in order to improve the quality of the first 76 and the leaf spring has a longitudinal groove for moving the adjuster in it.
