Abstract

The invention relates to computing and can be used in automated control and information processing systems. The aim of the invention is to improve the reliability of the keyboard. The keyboard contains a matrix of keys installed in the case, rotatable axes on which the pins are rigidly fixed, reciprocally. moving slats, transparent keys, switching elements, return springs, a removable storage medium, which shows a table with marking of each key and a code mask of the table number. The principle of action is based on the transfer of motion from pressing the Tojft key through the pivot axis and reciprocating rail to the switching elements of the column and matrix row, the response of which determines the number of the key pressed. A distinctive feature of the keyboard design is that, with constant overall dimensions, it provides an operative change of storage media made in the form of individual cards or roll material, which increases the amount of input information. 2 Il.

Description

The invention relates to computing and can be used in automated control and information processing systems.

The aim of the invention is to improve the reliability of the keyboard.

Figure 1 shows the keyboard structure, top view; figure 2 - section aa in figure 1.

The keyboard includes a housing 1, rotary axes 2, on which pins 3 are rigidly fixed, reciprocating rail 4, transparent keys 5, switching elements 6, return springs 7, removable information carrier 8, which shows a table with each key 5 marked (under matrix of keys) and-code mask of the table number 9.

Transparent keys 5 form a matrix and are installed in rows of the matrix on rotary axes x 2, at the output of which cams 10 are located, under each key 5 on the rotary axes x 2 are rigidly attached pins 3. On the column of keys of the matrix are installed from the end faces of the keys 5 reciprocating rails 4 with teeth 1 1; input into engagement with the protrusion 12 of each key of the 5th column. The rotary axes 2 through the cam 10 and the reciprocating rails 4 are compressed by the return springs 7. The switching switches 6 are installed opposite the outputs of the rotary axes 2 and the reciprocating slides 4. The protrusion 13 of the key 5 is installed in the window 14 of the reciprocating slats 4. Removable carrier 8 The information, which shows a table with the marking of each key 5 and the code mask of the table number 9, is set under the matrix of keys.

. The keyboard works as follows.

When pressing the key 5, its body rotates around the pivot axis 2 at an angle limited by the protrusion 13 of the key 5 in the window 14 of the reciprocating rail 4, and transmits movement through the pin 3 of the pivot axis 2. The rotary axis 2 rotates and the cam 10, fixed at the exit of the rotary axis 2, includes the switching element 6 of the given row of the matrix. At the same time, the movement of the key 5 is transmitted to the reciprocating rail 4 through the prong

1I, which is engaged with the protrusion 12 of the key 5. The reciprocating rail 4 extends and switches on the switching element 6 of this column of the matrix. When the key 5 is pressed, the remaining keys located on this row of the matrix remain in the initial position, since they are clamped by the teeth I1 of the reciprocating rails 4 that do not engage with the pressed key 5, and the remaining keys 5 located on this column of the matrix pinched by pins 3, fixed on the swivel axis x 2, on which the key 5 is not attached to the kata.

When the external action of the key 5 is removed, the pivot axis 2, the reciprocating rail 4 and the key 5 are returned by the action of the return springs 7 and the initial position. To change the labeling of the keys 5, it is necessary to install under the matrix of keys the carrier 8 of information with the corresponding table of markings of each key and the code mask of the table number 9.

Claims (1)

The storage medium can be made in the form of a map, which shows a table of key markings and a code mask of the number of this table, or in the form of a roll material. Invention Formula A keyboard containing a matrix of transparent keys located in the housing, a removable storage medium mounted under the matrix of transparent keys, characterized in that, in order to increase the reliability of the keyboard, a coordinate mechanism in the form of spring-loaded pivot axes with pins and return- translational rails with teeth, switching elements, and the rotary axis is installed in each row of the matrix of transparent keys in the holes, made in the upper part of the keys, under each of which there are enes pins in each column of the matrix by the transparent keys of end faces of the keys is located a reciprocating rack with teeth, the input conductive engagement with each transparent key, against one of the ends of the pivot axes and reciprocating rods arranged switching elements. 6 7 four ten Fy 671 g. 3 LLA : rK5 "" i5S5 :: r: 5S55iitis i: "5r;" e Compiled by O.
