Printing unit in calculating machines

The invention relates to a printing unit in calculating machines, especially in fully automatic four-species calculating machines, which a voix Hand adjustable device for printing a fixed point have and in which the printing of the zeros to the left of a value by one of stops and counterstops

formed "living bridge" is prevented!

It is already known to have calculating machines with a manually presettable device for printing a fixed point to provide. Here is a arranged in the machine, with; an adjustment knob provided control linkage in each desired place in the printing unit a comma type in the active position brought and in the subsequent printing process with the Values are printed.

It is also known (Swiss patent Hr. 392 94-1, Kl. 42m / 29), the printing of all covers to the left of one Value by a "living bridge" to prevent which from Counter-strikes attached to the setting wheels of the type wheels and the next higher on the print hammers Value point attached stops is formed. At this However, no decimal point is provided for this facility.

The object of the invention is the aforementioned in a printing unit Calculating machines to create a facility which can be used for printing a numerical value with a comma "automatically, which releases the first print position to the left of the set comma, even if it has no value. The facility is supposed to be simple and cheap to manufacture and made from as much as possible few additional parts.

According to the invention, it is proposed to attack the counter stops of the print hammers provided on the left of comma types or comma type levers, which are firmly connected to the pressure hammers of the next higher printing point, connected and aurca a comma type lever Sirtstellgestänges laying in the printing position can be adjusted in an ineffective position, whereby the print hammer arranged on the left of a Koasatype brought into the operative position and thus all the type wheels provided to the right of this, which do not contain any value, are released for printing zeros. ; .

Between the two levers 19, 19 ^f , a control member 24 attached to a shaft 23 is provided. On both sides * of the control member 24 there is a switching pin 25 offset from one another at an angle of rotation of 90 ° or 120 °.

By turning the square shaft 23, the switching pin 25 releases the lever 19 again and finally the retaining pin 26 engages an arm 27 'of the lever 19 ¹ ' and pivots it clockwise.

All print hammers 2 in the Pig. locked position , the type wheels 7 contain no value and the comma type levers 15, "15 *. are held in the inactive position by the levers 19, 19 'corresponding to the type lever 15 *. By entering a value in a type wheel, the associated Adjustment wheel 9 provided counterstop 33, 35 in its ineffective position. During the subsequent printing process, the locking bar 5 is pivoted upwards and the printing hammer 2 carrying the type wheel 7 containing a value is released 36 ', all print hammers 2 arranged to the right of this point (in the Pig, left) are triggered, even if their type wheels are set to "zero." The print hammers 2 to the left (in the Pig.

in which he swings the lever 19 clockwise. Through this the pin 20 releases the command lever 15, v / elcher below the force of the spring 16 pivots in the printing position. Simultaneously The pin 20 engages the switching edge 39 of the switching element and pivots it counterclockwise, whereby the Stop 36 the associated counter-stop 35 to the left of Releases value position arranged with a comma. That’s the printing unit set.

If, for example, a value "15, 16" is printed, the presetting made by the slide 30 remains ineffective because the fourth print hammer 2, seen from the left in the FIG., Is free by turning its input wheel 9. If the The value to be printed, however, is less than ¹ M ", ie z. B. "0.24" or "0.03", after the printing hammer 2 has been released by the locking bar 5, the first printing hammer 2 on the left (on the right in the figure) - provided by the comma - will always be printed, since its counter-stop 35 was already released by the stop 36 before the start of the calculation. When printing values that are smaller than "1", the value position adjacent to the decimal point on the left is printed as "zero".

By adjusting the slide 30 by one more detent there, the control pin 25 of the control member 24 releases the lever 19, while the control pin 26 engages the lever 19 'and by swiveling the 5 type lever 15 * in the pressure position and Swiveling the stop 36 'into its ineffective position Printing unit as described on three value places to the right of Comma sets. -
