Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device for displaying data entered on a keyboard, particularly on the keyboard of an electronic typewriter. The present invention relates to a display device comprising an optical display having a first area for display.

Constantly displays various data necessary for the operator, such as the number of characters required to complete a line of printing Display devices of the type consisting of a matrix of (optical dots) are known.

Other machine condition data that can be manually controlled, such as print pitch, print type, line space, etc., are displayed using other devices. When a multi-position selector is used, the display is provided by a scaled finger associated with a slider that controls various conditions. If you use function keys that are activated several times in a programmed sequence,
Similar to various mechanical condition data, the display cannot be performed depending on the position of the key, but is displayed using a plurality of optical indicators that selectively light up depending on the mechanical condition applied to the key.

The object of the invention is to provide a simple and inexpensive display device capable of displaying data relating to machine conditions and data relating to individual key actuations.

The display device of the present invention is characterized in that a screen marked with various machine condition data that can be manually operated is arranged in association with a second area of the display, and the optical elements of this second area are marked with various machine condition data that can be manually operated. selectively illuminates to indicate machine conditions.

Referring to FIG. 1, a display device 20 is incorporated into an electronic typewriter 21 of known type. Typewriter 21 has a keyboard 22, a platen 23, and a serial printing unit 24.

The keyboard 22 consists of a plurality of letter, number, and symbol keys 25, a group of function keys 26, and a group of keys 27-32 for setting machine conditions. In particular, key 27 presets the editing functions of the machine, i.e., determines whether characters are printed normally, in bold, underlined, or vice versa. . Keys 28 preset the machine to use specific characters and symbols that do not belong to standard keyboard layouts. Key 29 is Ko inch (2,54111++
), A2 inch (2,12), A5 inch (1,69
0) and PF3C proportional), and the key 30 is used to select the necessary printing pinch such as 1 step, 1.5 step, 2 step, 2.5 step,
This is for selecting a line space such as 3 steps. Key 31 is used to set the right margin stop of the print line. The key 32 selects the following four machine states (
One of the following options is selected: TP, age ~, L/shi, ST. In addition, TF' prints the selected character immediately, W
/w is printing per word, L/L is printing per print line, and ST is recording the selected character in the (machine's) memory.

The display device 20 is mounted on the same console as the console equipped with the keyboard 22 and has a liquid crystal display 39, which has 16 (rows) x
A first area 4 defines a dot matrix of 160 (vertical columns) and displays characters and symbols corresponding to the operated keys 25.
0 (Figure 2), the selected print strength value, the intended paragraph display, the number of characters that can be printed before the right margin stop (the example in Figure 2 shows that 158 characters can still be printed), etc. and a functional area 41 for displaying the amount of permanent memory of the machine.

The display device 20 comprises a second upper area 45, adjacent to which a screen 46 is located, on which are marked or printed symbols relating to the various machine conditions that can be entered by means of the keys 27-32. It is.

The light elements 47 of the display 39 are arranged to selectively illuminate in association with symbols associated with keyed machine conditions to provide a permanent indication for the operator. In particular, each machine condition is indicated by simultaneously lighting up ten light spots in the first and second rows from the top of the matrix. On the other hand, all the dots in the third row remain illuminated at all times and represent a line separating the upper area 45 and lower area 40 of the display 39. - In the example of FIG. 2, the light element 47 indicates that the machine or typewriter 21 is set to the following conditions. That is, printing in bold letters, only keys in the normal keyboard layout can be used, and the printing pitch is 1/15.
Inches, line spacing is 2, right margin stop is valid, and line-by-line printing is indicated.

If you want to change one of the machine conditions, press the corresponding key 27
.about.32 is activated once or several times to bring the light element 47 to a position (on the screen 46) corresponding to the desired conditions.

In order to make the display 39 easier to read from an economic point of view, the display 39 is hinged to the machine 21 at a hinge axis 48 and the display 39 can be manually moved (
around the hinge axis 48). Furthermore, the brightness of the display 39 can be changed by operating a predetermined code key on the keyboard 22.

The use of the display device 20 described above is not limited to typewriters, but can also be used in machines whose operating conditions can be selectively varied.
