Definitions

  • the present invention relates to an arrangement according to the introductory part of claim 1 for displaying the data which are entered on a keyboard, in particular the keyboard of an electronic typewriter.
  • a display arrangement of the type comprising a matrix of light dots is known from US-A-4 323 315, which comprises a first or working region for progressively displaying the characters and the symbols corresponding to the keys which are actuated by the operator, and a second or service region which constantly displays variable data which are useful to the operator, such as the number of characters which are required to complete the row of typing.
  • Other machine condition data which can be keyed in, for example the typing pitch, kind of printing, line spacing and so on are selected by multi-position selectors and are displayed by the positions of the sliders of the selectors on associated graduated scales.
  • the display arrangement of this reference is not adapted to display machine conditions on machines devoid of selectors and in which the conditions are selected by actuation function or service keys several times, in accordance with programmed sequences.
  • Another display arrangement is known from GB-A-2 087 115 which relates to an electronic typewriter provided with a dot matrix display for displaying the entered characters and a series of groups of LEDs at the sides of the display which selectively light up to light associated scales, according to the machine condition which is keyed in.
  • a display arrangement of this type results rather costly.
  • each model of typewriter providing different conditions would require different groups of LEDs and scales for displaying the different conditions.
  • the object of the present invention is to provide a simple and economic arrangement which permits display both in respect of the data relating to the machine conditions and the data relating to actuation of the individual keys.
  • the arrangement according to the present invention is characterised by a screen marked with various machine conditions which can be keyed in and which screen is disposed in association with a third region of the display device, and in that the light elements of the third region are selectively lighted to indicate the machine conditions which have been keyed in.
  • a display arrangement 20 is shown fitted to an electronic typewriter 21 of known type.
  • the typewriter 21 comprises a keyboard 22, a typing platen cylinder 23 and a serial print unit 24.
  • the keyboard 22 in turn comprises a plurality of alphanumeric keys 25, an array of service or function keys 26 and an array of keys 27 to 32 for keying in machine conditions.
  • the key 27 is arranged to preset the editing function of the machine, that is to say, whether the characters are to be typed normally, in heavy type, underlined or in reverse;
  • the key 28 is arranged to preset the machine for the use of particular characters and symbols which normally do not belong to a standard keyboard layout;
  • the key 29 is arranged to select the type of spacing which is required; 1/10" (2.54 mm), 1/12" (2.12 mm), 1/15" (1.69 mm) or proportional;
  • the key 30 is arranged to select the line spacing as between 1,1.5, 2, 2.5 and 3 elementary steps;
  • the key 31 is arranged to set control of the right-hand margin of the line of print; and
  • the key 32 is arranged to select a machine state among the four possible states: TP which permits immediate typing of the character selected, W/W for typing which is deferred for a word, UL for typing which is deferred for a line, and ST which permits the selected characters to be recorded in a memory of the machine.
  • the arrangement 20 is mounted on the same console which carries the keyboard 22 and comprises a display means or display device 39 which is formed from liquid crystals, defining a matrix of 16 rows by 160 columns of dots and having a first region 40 (see Figure 2) for displaying the characters and symbols corresponding to the actuated alphanumeric keys 25, and a second service or function region 41 for displaying the amount of permanent memory of the machine which is occupied by data, the value of the selected strength of strike, the indented paragraph indicator and the number of characters remaining up to the righthand margin (the figure 158 in the example shown in Figure 2).
  • a display means or display device 39 which is formed from liquid crystals, defining a matrix of 16 rows by 160 columns of dots and having a first region 40 (see Figure 2) for displaying the characters and symbols corresponding to the actuated alphanumeric keys 25, and a second service or function region 41 for displaying the amount of permanent memory of the machine which is occupied by data, the value of the selected strength of strike, the indented paragraph indicator and the number of characters remaining
  • the arrangement comprises a third, upper region 45 adjacent which there is disposed a mask or screen 46 which carries printed symbols relating to the various machine conditions which can be keyed in by means of the keys 27 to 32.
  • Some light elements 47 of the display device 39 are arranged to be lighted selectively in association with the symbol associated with the keyed-in machine condition, to provide a permanent indication thereof for the operator.
  • each condition is signalled by the simultaneous lighting of ten light dots of the two upper rows of the matrix, while all the dots of the third row remains constantly illuminated to indicate the line of separation between the upper region 45 and the lower region of the display device.
  • the light elements 47 indicate that the machine 21 is set up to operate in accordance with the following conditions: heavy-face printing; option of using only the keys of the normal keyboard layout; pitch of 1/15" (2.12 mm) line spacing 2; right-hand margin justification; and typing deferred by a line.
  • the corresponding key 27 to 32 is actuated and possibly the operation is repeated until the light indicator 47 associated with the machine condition which is to be changed indicates that the machine is in the fresh condition required.
  • the device is hinged along its bottom portion on the bodywork of the machine 21 and can be manually tilted by the operator with respect to its hinge axis 48.
  • the brightness of the display device 39 can also be varied by operating predetermined code keys of the keyboard 22.
