Definitions

  • FIG. I shows three inputs I0, 11 and 12 at which are furnished timing and data signals, the former for control purposes, the latter for print-out.
  • coded signals are applied at input 10. These coded data signals may, for example, signify numbers which are entered into or printed out for an associated desk calculator, herein also referred to as computing means.
  • the coded data signals are stored in a storage 13.
  • Input 11 is that input of logic circuit means 14 whereat operations signals, that is signals signifying particular arithmetic operations to be carried out by the desk calculator, are received.
  • Timing signals are applied at input 12 to motor control means 15 whose output controls the motion of step-motor 16. Step motor 16 in turn moves a feed means 18 and printout means.
  • An operations key 29 is then depressed, which causes the corresponding operation to be set up in the computer.
  • the operation of a key 29 causes an operation signal to appear at input 11 of logic circuit means 14.
  • the first motor control signal is then furnished to motor control means by circuit 14, upon simultaneous receipt of the input signal at input 11 and of an inputsignal at input 12 which corresponds to the unit energizing signal energizing Mixie tube 30a (see also FlG. 2).
  • Motor control means 15 comprise a ring counter 15a (see FlG. 7) receiving the motor control signals at the first input (R).
  • the ring counter output 15a comprise three flip-flops each of whose states (rt-,0) is determined by the count of the ring counter lSa.
  • said storage means comprise means storing a number of coded signals corresponding in number to the number of coded data signals required for an individual character only.
