Gate 319 is still controlled in this way by the circuit 321 itself that it is only able to activate the latter after it has returned to its stable state. The circuit 321- then energizes the printing-controlling electromagnet 63 for a period of about 200 ms, which controls one revolution of the main shaft 34 (FIG. 5), whereupon the set data are printed in the book 222 "As the energization of the electromagnet 63 is of shorter duration than the circulation

of the main shaft 34, the shaft is stopped in any case at the end of the revolution * In addition, the circuit transfers

321 (I ¹ Ig. 10) the slip-flop 333 via the gate 336 to another state, whereupon any further search for characters is blocked. Finally, the circuit 321 switches off the circuit 318, so that the electromagnet 160 deenergizes in any case and causes the tooth to come back into engagement with wheel 129 (FIG. 4), regardless of whether the last tooth that was in engagement with it before the printing process was tooth 143 or tooth 144 "

During the pressure circulation, the adjusting wheel 108 returns to the rest position in the transverse direction, whereupon the Miniature switch 156 opened At the end of this return movement, the wheel 129 is blocked by the tooth 143, which thereby controls the miniature switch 156 closes again, which again transfers the circuit 333 to another state and a new one Character search and triggering of register 324 causes

If it is in the signal received by the central unit code to a printable character or a space, the selection of a new Druekreihe executed as previously described begins · If the other hand, if the newly received code to an "end of message ^lt -Gode, this indicates that the process of printing in the book is complete ο The decoder 315 then emits, in addition to the ON signal, an OF signal, which is sent to the gate

322 goes. Because the small switch 245 is then also closed, the gate 322 transfers the circuit via the gate 325

323 into a different state, whereby the circuit 323 on the one hand triggers the register 324 via the gate 337 and on the other hand, causes the eject solenoid 303 is excited · The book 222 (Fig · 1) is then on already loaded

ejected manner, whereby the miniature switch 245 is opened, while the wheel 272 (Fig. 7) together with the Car 249 (Pig · 1) is returned to its resting position.

The trolley now causes the small switch to close 303, whereupon circuit 328 (Hg · 10) completes the circuit of the motor M interrupts the closing of the switch 303 also causes the switching off of the circuit 323, so that the electromagnet 302 is de-excited while it causes the switching off of the circuit 332 via the gate 334

When the book 222 (FIG. 1) reaches the end of its path after a row has been printed and the mini switch 314 closes so this switch switches via the converter 320 (Pig10) the gate 319, whereupon the circuit 321 does not control the printing even if the wheels 11 (Fig * 1) already are set · Closing the small switch 314 also causes the transfer of the Circuit 323 »with the result that the book 222 (Fig. 1) is ejected as in the previous case Wheels 11 set data can be found on a new page can be printed by inserting the book 222 into the device and after closing the mini switch 245 as before described is continued »

Of course, various changes, improvements and additions of parts are made to the device without departing from the inventive concept. So can the device be provided with a back key, for example, in order to bring the register 324 back to zero in a known manner at the beginning of a number of & ruek processes
