Definitions

  • the invention relates to a method specified in the preamble of claim 1.
  • a difficulty in the operation of typewriters or similar machines lies in the fact that after a shift to a character that has already been printed out, for example for the purpose of a correction, the printing unit must be reset to the end of the text that has already been written, to continue typing.
  • the operator was forced to carry out these resets by triggering the step switching manually accordingly and additionally to check the exact taking of the end position.
  • corrections are made relatively frequently in the text already written, so that manual resetting requires a noticeable time requirement.
  • This known device is limited to automatically resetting the printing unit when moving along the last line written. It is helpful in all cases in which the operator already has shortly after entering or printing an error, this is immediately noticed and corrected immediately.
  • the invention is based on the object of eliminating the limitation given to the solution from the known prior art to automatic resetting after printing unit displacements which only occurred along the last printed line.
  • the advantages of the invention are in particular that the operator of such a machine text corrections, for. B. the improvement of errors, the deletion or insertion of a character, etc. at any point of the printed text and that the printing unit moved to such a correction point after triggering a reset function automatically reset to the next free print position after the last character of the last line becomes. After making any number of corrections at any point in the printed text, the operator only needs to press a reset key in order to then be able to resume continuous text input.
  • FIG. 1 The block diagram of a typewriter according to the invention shown in FIG. 1 only has the elements necessary for understanding the invention, namely a keyboard 1, a printing unit 2 and a control unit 3 with a program memory 4 and a data memory 5, which are connected via a bus 6 are interconnected.
  • Control unit 3 program memory 4 and data memory 5 are part of a microprocessor control 7 of the machine, which is why all of the components mentioned below, which participate in the control, such as. B. counters and comparators, can basically be replaced by program routines.
  • a step-by-step motor 10 serves as the drive for this.
  • a printing unit 11, which has a rotatable type plate 12 as the type carrier, can be moved horizontally in the direction of arrows C and D by a further step-by-step motor 13.
  • the characters of a text line can be printed side by side on the record carrier 9 by horizontally shifting the printing unit and adjusting the type plate 12 to the character to be printed, while 9 text lines can be arranged one below the other by vertically shifting the record carrier.
  • the keyboard 1 has, in addition to a character keypad 14 with which characters can be entered, various function command keys, of which only one key 15 for the upward movement of the recording medium 9, one key 16 for the downward movement of the recording medium 9, one key 17 for the left shift of the printing unit 11, a key 18 for the right shift of the printing unit 11 and a key 19 for triggering a reset function of the printing unit 11 are shown.
  • a keyboard query carried out in rapid succession determines which of the keys on the keyboard 1 has been pressed. If, for example, the command key 15 has been actuated, prompt
  • the key code derived therefrom means that in the processor control 7 of the machine the number of steps to be carried out - depending on the frequency of the key actuation or the basic step number underlying a feed step of the recording medium - is added in a vertical counter 20 with a positive sign to a possibly already existing value and saved.
  • step-by-step controllable motor 10 is actuated, which moves the record carrier 9 in the direction of arrow A, that is to say upwards, with the commanded number of steps.
  • the command key 16 has been actuated, its key code causes the controller 7 to add the commanded number of steps with a negative sign in the vertical counter 20 and to actuate the motor 10 to shift the recording medium 9 in the direction of arrow B by this number of steps.
  • the vertical counter 20 therefore always contains the number of steps by which the record carrier 9 is displaced in the vertical direction with respect to the printing unit 11. The sign of the counter content indicates the direction of movement.
  • Each step triggered by a key actuation for a vertical or a horizontal feed can consist of several elementary steps which the respective motor 10, 13 has to carry out, without changing the inventive idea.
  • a corresponding number of control signals are applied to the motors 10, 13, and the number of elementary steps of the feed step triggered in each case is used for the associated step counters and calculations.
  • FIGS. 2A and 2B for the sake of simplicity, only one counter step and one feed step are used as a basis for each step trigger.
  • a query of the vertical counter 20 is carried out in the controller 7 as to whether a value contained therein has a positive sign.
  • the V ertikalSullivaner 20 not be negative and contain only a carriage return a positive value. If such a positive value is determined, the vertical counter 20 is set to zero. However, if the record carrier 9 has been moved downward by previously pressing the key 16 so that the printing unit is above the last print line, the vertical counter 20 contains a value with a negative sign. This value is not deleted when a character key is pressed.
  • the controller 7 causes the type plate 12 to be rotated into the printing position with the character corresponding to the actuated character key.
  • the sign is then printed in a known manner.
  • the character code of the cut character is also stored in the data memory 5 and, in association with it, in a further memory location the horizontal position of the character taken from a horizontal counter 21. Now the motor 13 is shifted to the right to shift the printing unit 11 by one column position into the next impression point and the horizontal counter 21 is increased by one step - or a corresponding number of elementary steps.
  • the horizontal counter 21 which is provided to count each step movement of the printing unit 11 from the beginning of the line - depending on the direction of movement by adding or subtracting the corresponding number of steps - thus always has information about the current position of the printing unit.
  • Is z. B. operated the command key 17 the printing unit 11 is shifted one column step in the direction of arrow C to the left, and the content of the horizontal counter 21 is reduced by one step.
  • actuation of the command key 18 has the result that the printing unit 11 is shifted to the right by one column in the direction of the arrow D and the content of the horizontal counter 21 is increased by one step.
  • the recording medium 9 for the purpose of correction by a certain number of steps in the direction the arrow B vertically downwards and the printing unit 11 has been shifted horizontally to the left by a few steps in the direction of the arrow C.
  • the operator has made the desired correction and now presses the command key 19 to reset the printing unit 11.
  • the control determines whether the vertical counter 20 set with the number of steps during the vertical displacement of the recording medium 9 has a value with a negative sign. In the affirmative, the motor 10 is actuated for the upward displacement of the recording medium 9 in the direction of the arrow A with simultaneous addition of the steps to the counter content until the vertical counter 20 has reached the value zero. This is followed by a search in the data memory 5 for the highest stored position of a printed character.
  • This position is read out and increased by one column step.
  • the value obtained in this way is compared with the content of the horizontal counter 21, which indicates the current position of the printing unit 11, in a comparison device 22.
  • the printing unit position is smaller than the target position read out from the memory and increased by one column step.
  • the printing unit 11 is moved by the motor 13 while adding the steps to the content of the horizontal counter 21 to the right in the direction of the arrow D until the comparison gives the value zero.
  • the printing unit is now set to the first free printing position to the right of the last character already printed in the bottom line, and the operator can continue with the text input.
  • the printing unit 11 had been on the right of the target position read from the memory and increased by one column step, the comparison of the contents of the horizontal counter 21 with the target position would have shown that the horizontal target position is smaller than the current position of the Printing unit 11.
  • the motor 13 would then be driven to carry out a feed movement in the direction of arrow C to the left, and the number of steps in the horizontal counter 21 would have been subtracted until the comparison would have again given the value zero. Even then the printing unit would have been set to the first free printing position to the right of the last character.
  • the printing unit 11 then faces the unlabelled recording medium 9 below the already printed text, and the vertical counter 20 contains the number of steps carried out with a positive sign. If the reset command key 19 is now actuated before a character key has been actuated, a check of the vertical counter 1 shows that there is a positive value.
  • the motor 10 is then actuated to carry out a displacement movement of the recording medium 9 in the direction of the arrow B, until the correspondingly reduced content of the vertical counter 20 reaches the value zero.
  • the printing unit 11 is then reset to the last printed line, and any necessary reset in the horizontal direction is carried out in the manner already described above.
