! irma DIEHL, Nuremberg, Stephanstrasse 49 Keypad for data processing machines and systems

The! Inflation relates to a keypad for data processing Machines and systems, especially for program-controlled desktop computing machines, which are spatially adjacent, has a numeric keypad and a puncture keypad.

The task of the innovation is to provide means in the keypad of such machines to freely select and bring in frequently recurring To provide work programs as well as to repeat these programs at will and to arrange them so that they are easy can be operated with the appropriate keys for entering or repeating the program.

According to the innovation, it is therefore suggested to enter a freely selectable work program in the puncture keypad of the Mas.chine to arrange a program setting button, while a Program call key is assigned to the ten-key block in such a way that that it can be operated easily with the keys of this block, this call key mainly on one of the long sides mentioned above Blocks over its entire length.

A release or release slide is adjacent to the program setting button assigned, by actuating a preset program by actuating the program setting button again . can be deleted or overwritten

Details of inflation can be found in the description of two Embodiments shown in the drawings. Show it:

1 is a perspective view of a program-controlled desktop calculating machine with a keypad according to FIG

! Inflation,
Pig. · 2 is a plan view of a keypad after inflation

for a machine after Pig. 1, ■ Pig. 3 shows another arrangement of the keys in a keypad

after Pig. 2,
Pig. 4 a sectional view according to IV - IV in Pig. 2.

Pig's desktop calculating machine. 1 is arranged in a housing 1 made of metal "or plastic. The housing 1 has a stepped, slightly sloping surface 2 at the front,

in which a keypad 3 is housed. Above the keypad 3 is a viewing window 5 in a steep housing surface 4 Display of the number of digits keyed in and for display of any preset plague commas. The adding machine is also equipped with a printing unit 6, the paper roller 7 of which is additionally manually operated by a knurled knob 8 is further rotatable. For better reading of a printed value, the housing 1 has a shoulder 9.

A key field 3 is shown in Figure 2, which is essentially divided in a known manner into a ten-key block comprising the value setting keys "OV to" 9 "and a function key block "Print" -! · Key 12, a multiplication key 13, a subtotal key 14, a grand total key 15, a result key 16, a constant call key 17 for a first

Constant work, a constant call button 18 for a second Constants, a root key 19, a division key 20, a memory addition key 21, a memory subtraction key 22, a memory subtotal key 23, a memory grand total key 24 and a program setting button 25. To the right of the

Program setting button 25 is the same in its basic position locking release or release slide, which will be explained in more detail later 26 arranged displaceably in a slot 27.

Is used before the start of a computer program, relocating the J release slide 26 to the back, the program setting button 25 is pressed, this is subsequently done with the puncture buttons 10 to 20 The program entered is registered and stored in the machine until the program setting button is pressed again.

To the right of the function key block is a with a pointer. 28 provided, in a slot 29 along a fixed scale 30 relocatable comma slide 31 for presetting a fixed decimal point. By moving the comma slider 3.1 calculates the machine according to scale 30 with two, four, six or eight decimal places to the right of the decimal point. The setting a comma during a value entry is done by pressing

a comma key 32, which is arranged in the ten-key block and can be easily operated instead of a value key, approximately correspondingly The decimal point default setting, missing, not keyed places to the right of the decimal point are automatically replaced by lulls.

Immediately to the left of the value input keys "1" to "9" there is one for entering a value in the first set of constants Serving constant setting button 33, a constant setting button 34 and a value entry in the second set of constants a delete key 35 which deletes the last keyed in value is provided. The buttons 33, 34, 35 are slightly with or in front of them or after pressing a value key.

to the left of the numeric keypad or the keys 33, 34, 55 is one that runs over the entire height of the numeric keypad and is also easy to operate with the value input keys Program call-up or automatic key 36 is provided. A program entered by the program setting key 25 can can be repeated any number of times by simply pressing the automatic key 36 after entering a new numerical value will. Interim bills, such as B. simple multiplications and / or divisions by the appropriate Puncture buttons possible at any time without changing the program.

In the keypad 3 according to FIG. 3, the total key has 15 and the memory grand total key · 24. a spatially different arrangement. Next is in Pig. 3 to the left of the scale 30 is a rounding slide provided with a pointer 37 and displaceable in a slot 38 39 provided. This results in a result in a desired number of decimal places on the right in a known manner rounded up by the comma.

In Pig. 4 is the memory addition button 21, the memory ι subtraction key 22, the program setting key 25 and the Preigabe- I

Slide 26 of the keypad 3 shown from the side. The program setting button 25 is fastened to two shafts 40, 41 of a frame 46 which is guided displaceably with a bracket 42 in a frame wall 43 and with an arm 44 in a rail 45 fixed to the frame. In rest position of the frame 46 is under the force of a \ other end to a fixed in the frame wall 47 rail "jj 48 engaging Peder j 49 with an arm 50 at an angle rail,

51 at. The arm 50 protrudes at the same time into a slot 52 of a ball lock 53 which is assigned to all keys in common

The frame 46 is supported by a 'pin 55' on the side in a with the release slide 26 connected lever 54 is attached, gripping under, whereby an actuation of the program setting button is prevented-. Opposite by verbs of the price slide 26 the force of a spring 56 acting on the lever 54 On the right, the pin 55 releases the frame 46 and this can be moved downwards by pressing the program setting button 25. The arm 50 engages in the ball lock 53, while the frame 46 on a leaf spring 57 of a macro switch takes effect and the program storage switches on. In the rest position, the program setting button 25 is automatically activated again by the Pin 55 locked. ·
