Description

DETAILED DESCRIPTION OF THE INVENTION (i) Technical Field The present invention relates to an electronic typewriter, and more particularly to a means for storing input print control information, and a method for storing a plurality of prints according to the control information stored in the storage means. The present invention relates to an electronic typewriter having a printing means capable of printing in a mode.

(ii) Prior Art In recent years, there has been an increase in the number of electronic typewriters that perform printing under electronic control by introducing control elements such as microprocessors and storage elements such as RAM. These types of typewriters are more multi-functional than previous manual or electric typewriters, and can store input character strings and print them line by line, or print them out line by line. It has multiple printing modes such as centering, layout, and text to print at the desired printing position, or it also has left and right margins, tabs, printing pinch, line pitch, printing pressure, bold printing, printing with underline, There are known printers equipped with input means that allow the operator to determine desired values for various print control parameters such as.

These printing modes and parameter input methods include methods in which corresponding input switches are provided, or methods in which input is performed using a plurality of keys provided on the keyboard or a combination of switches. However, if these switches are not provided on the operation surface (keyboard) or if input is performed using a combination of multiple keys, it is difficult for the operator to know what is currently being input as a printing parameter and how to do so. It is difficult to check whether the printer is in the correct print mode. There is also a known mechanism that sets left and right margins, tabs, etc., and generates a warning sound if the settings overflow. It becomes difficult to determine what the sounds mean.

(iii) Purpose The present invention has been made in view of the above points, and an object thereof is to provide an electronic typewriter that can reliably notify an operator of print control information such as print control parameters and print mode. do.

(iv) Examples Hereinafter, the present invention will be described in detail based on examples shown in the drawings.

FIG. 1 shows the appearance of an example of the electronic typewriter of the present invention. In the figure, a keyboard 13 designated by the reference numeral 13 is used to input a print character string, print control information, etc., and is arranged on the operation surface on the front side of the main body of the apparatus. A known printing mechanism consisting of a platen, a print head, etc. is provided in front of it. A display device 14 according to the present invention for displaying print control information is centrally provided on the right side of the keyboard 13.

FIG. 2 shows an embodiment of the electronic typewriter control circuit of the present invention.

Print character information and print control information input from the keyboard 13 are sent via the information input section 15 to a control section 6 such as a microprocessor and a storage section 17 composed of a RAM or the like. The control unit 16 determines whether the input information is print character information or print control information, and sends the print control information to the storage unit 17.

The control unit 16 is a print control unit 2 connected to a known printing mechanism.
The print control unit 22← is connected to a sensor unit 21 that detects malfunctions such as the above-mentioned paper feeding abnormality and margin excess. The detection output of this sensor section 21 is fed back to the control section 16 via the print control section 22.

Further, a display data storage section 18 is connected to the storage section 17 and the control section 16. Information to be displayed out of the printing control information is sent from the storage section 17, and based on the data in the display data storage section 18, the display data storage section 18 is connected to the storage section 17 and the control section 16. The lighting of each indicator of the display device 14 is controlled via the display drive device 19.

As shown in FIG. 3, the display device 14 displays, for example, a print mode and print control parameters on its display surface.
It is configured by arranging display devices 1-12. Here, the display l indicates the centering mode in which the input character string is printed at the center position of the printing paper, the display 2 indicates the indentation mode in which the end of the printed character string is aligned, and the display 3 indicates the text and character string. Display 4 indicates a layout mode in which the input character string is printed at the operator's desired position.Displays 5, 6 and 12 are for warning. On the display of
The display 5 indicates that input has been made beyond the set left and right margins, the display 6 indicates the presence or absence of printing paper, and the display 12 indicates that an incorrect key was entered manually during processing in a specific mode. This indicates that the

Further, displays 7 to 11 display settings of input printing control parameters, display 7 indicates the print character pitch, display 8 indicates the print line pitch, and display 9 indicates the print line pitch.
indicates the printing pressure, Display 10 indicates whether to print or not print every 3 digits when inputting numbers, and designate the position symbol, period, comma, etc.; Display 1
1 indicates the type of font.

The above-mentioned display device displays information by placing an LED, a lamp, etc. under a semi-transparent board on which information is printed, and lighting it up.

In the above configuration, the keyboard 13 allows, for example,
The print mode is centering mode, the character pitch is 10, and the line pitch is 11/2. Assuming that the following parameter settings are input: printing pressure is 4, number scale is printed in periods, and font is bold (bold), these print control information are sent to the control unit 16 and the storage unit 17. These pieces of information necessary for white display are transferred to the display data storage section 18. The control unit 16 controls the display data storage unit 18 based on the display data in the display data storage unit 18, so that the display l, It can be seen that the portions of the displays 7, 8, 9, 10, and 11 corresponding to the input print control information are lit. The lighting of each display corresponds to the input print control information, and the display 1 indicates the centering mode, the display 7 indicates the character pitch is 1o, the display 8 indicates the line pitch 1 1/2, and the display 9 indicates the centering mode. The following parameter settings are displayed: the printing pressure is 4, the display 10 prints numbers in periods, and the display 11 prints bold fonts. This allows the operator to reliably recognize the printing parameters and printing mode.

When the sensor unit 21 detects the above-mentioned paper feeding abnormality or an input exceeding the margin setting, this detection output is sent to the control unit 16 via the print control unit 22, and the control unit 16 stores the display data. The display device 6 or the display device 5 corresponding to each error is turned on via the section 18 and the display drive device 19. Further, if an erroneous input is made during the specific mode processing, the control section 16 similarly lights up the display 12 via the display data storage section 18 and the display driving device 19. This allows the operator to reliably recognize erroneous operations and malfunctions.

(v) Effects As is clear from the above explanation, according to the present invention, the printing state such as printing control information, printing mode, etc.
