Abstract
Description
- 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.
- Display arrangements are known, of the type comprising a matrix of light dots, which comprise a service or function 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, and a working region for progressively displaying the characters corresponding to the keys which are actuated by the operator. Other machine condition data which can be keyed in, for example the typing pitch, kind of printing, line spacing and so mare, on the contrary, displayed using other means. When employing multi-position selectors, the display is provided by the graduated scales associated with the sliders which control the various conditions. When using function or service keys which are actuated several times, in accordance with programmed sequences, the display cannot be provided by the position of the key, which is the same for different machine conditions, but is effected by means of a plurality of light indicators which selectively light up, according to the machine condition which is keyed in.
- 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 is disposed in association with a second region of the display device, and in that the light elements of the second region of selectively lighted to indicate the machine conditions which have been keyed in.
- The invention will be described in more detail, by way of example, with reference to the accompanying drawings, in which:
- Figure 1 is a plan view of a typewriter with an arrangement according to the invention, and
- Figure 2 is a detail view on an enlarged scale of the display arrangement.
- Referring to Figure 1, a
display arrangement 20 is shown fitted to anelectronic typewriter 21 of known type. - The
typewriter 21 comprises akeyboard 22, atyping platen cylinder 23 and aserial print unit 24. Thekeyboard 22 in turn comprises a plurality ofalphanumeric keys 25, an array of service orfunction keys 26 and an array ofkeys 27 to 32 for keying in machine conditions. More specifically, thekey 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; thekey 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; thekey 29 is arranged to select the type of spacing which is required; 1/10" (2.54 mm), 1/12" (2.12mm), 1/15" (1.69 mm) or proportional; thekey 30 is arranged to select the line spacing as between 1, 1.5, 2, 2.5 and 3 elementary steps; thekey 31 is arranged to set control of the right-hand margin of the line of print; and thekey 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, L/L 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 thekeyboard 22 and comprises a display means ordisplay 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 actuatedalphanumeric keys 25, and a service orfunction 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 right-hand margin (the figure 158 in the example shown in Figure 2). - The arrangement comprises a second,
upper region 45 adjacent which there is disposed a mask orscreen 46 which carries printed symbols relating to the various machine conditions which can be keyed in by means of thekeys 27 to 32. - Some
light elements 47 of thedisplay 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. In particular, 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 theupper region 45 and the lower region of the display device. - In the example illustrated in Figure 2, the
light elements 47 indicate that themachine 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. - In order to change one of the machine conditions, the
corresponding key 27 to 32 is actuated and possibly the operation is repeated until thelight indicator 47 associated with the machine condition which is to be changed indicates that the machine is in the fresh condition required. - In order to optimise the visibility of the
display device 39, from an ergonomic point of view, the device is hinged along its bottom portion on the bodywork of themachine 21 and can be manually tilted by the operator with respect to itshinge axis 48. In addition, the brightness of thedisplay device 39 can also be varied by operating predetermined code keys of thekeyboard 22. - Use of the above-described
arrangement 20 is not limited to typewriters but may be extended to any machines which can assume varying selectible operating conditions.
