DE3436113A1 - INPUT DEVICE FOR THE INPUT OF CHARACTER DATA, IN PARTICULAR CHARACTER DATA, IN AN ELECTRONIC DEVICE - Google Patents

Description

The invention relates to an input device for input of character data, in particular extreme character data, in an electronic device.

in various types of electronic equipment, which contain a microcomputer, it is desired that the types of input keys that can be used are limited aui a minimum number that can no longer be reduced. this assumes that an enter key has multiple input functions which are changed in a suitable manner in the input mode. However, there are restrictions here if Characters, for example Japanese "Kana" characters, Chinese characters or the like with the help a small number of input keys should. Especially when the frequency of the character input is relatively few or if the characters entered are relatively few in number, is the Expenditure of a large number of input keys and cumbersome input processes undesirable.

The object of the invention is therefore to provide an input device To create of the type mentioned, in which different types of characters using a small Number of input keys can be entered easily.

This task is made possible by the work features specified in the claim ge 1öst.

In the invention, a number of character groups, to be entered in a character generator saved. This receives address assignments and gives a corresponding character to the address in Sequence as a pattern signal. With the invention can Ver seil all kinds of characters, numbers, symbols and the like can be easily entered using a small number of input keys. The invention is therefore applicable even with small electronic devices with a low Number of input keys. As an entered character is played on a playback device and under Using a cursor (position indicator) is entered, are input errors compared to conventional input methods extremely low using the ASCII code.

On the basis of the accompanying figures, an exemplary embodiment The invention is explained in more detail. It shows:

Fig. 2 is a detailed block diagram for an embodiment the invention;

3 shows a schematic representation of the arrangement of character groups in a memory and

Fig. K is a flow chart for explaining the operation of the exemplary embodiment from.

In the Ausführungsbeispie1 shown in FIG a number of character groups to be entered, completely stored in a character generator 1. This receives address assignments and outputs the appropriate characters to the addresses in sequence as a pattern signal A group assignment device 2 optionally has in each case the character groups of a large number of groups in one section-by-section data processing or batch processing to. The character group, which is soft by the group assignment

direction 2 is addressed, successive fο 1gena from Character generator 1 read. The pattern signal thereof is visually reproduced on a reproducing device 3. The address the assigned group is temporarily stored in a group address memory 4 saved. Since the characters that belong to an assigned group on the playback device 3 are arranged and reproduced, an operator move a cursor along the sign below Use of a character input means 5 and a certain Select character whose address to a cursor address memory 6 is passed on. The in the cursor address memory The address entered is the address of the cursor on the rendering device 3. An address processing device 7 reads both the address of the cursor and the address of the group in the group address memory 4. The Address processing device determines the character address des into the character generator 1 through the character input means 5 characters entered and stores the character address in a character memory 8. The operator performs the above operation repeatedly, and thus a desired character is input and, if necessary, those stored in the character memory 8 can be used Character data is read and stored on the player 3

are reproduced ocier transmitted by other facilities will.

The embodiment will be explained in detail. In of Fig. 2 is a keyboard 11 with an RS key for one Start or stop command when entering character data, a Qsi button for assigning consecutive groups, one GR key for assigning consecutive character groups, a CN key to move the cursor to the right by one step, a CR key to move the cursor to the right a step to the left, an LD key for character entry, an LA key for character correction and one LD key for character data display. U'ie off 3, the characters that can be entered into the device are in 160 types, including the spaces. Each character is addressed and stored in a memory, as will be explained. the Characters are classified into groups Gl to G20. Every group contains eight characters. The address of each character is determined by the address assigned to each group and the Address indicating the order of characters in each group. The character groups are stored in a character generator 12. The character generator 12 generates a pattern signal for the character that comes from the keyboard 11 address assignment is equivalent to. A central processing unit (CPU)

13 contains a computer unit 14. The CPU is via a Address bus, a data bus and an R / W signal line with one Peripheral connected. A read-only memory (RQVI) 15 saves the control program of the facility.

A direct access memory (RAM) 16 is used as a data memory of the CPU. A group register 17 stores the address of the character group. A cursor register 18 stores the address of the cursor present on a playback device 19, as will be described below. The group register 17 is counted by the RS key, the GN key and the GR key on the keyboard 11. The cursor register 18 is counted by the RS key, the CN key and the CR key on the keyboard. The output signal of the group register 17 is passed to a coincidence circuit 20, in which the coincidence of the output signal, the group register 17 and the clock pulses of a clock circuit 21, which specifies the raster on the display device 19, determines. If there is coincidence, a cursor playback signal 22 is generated. A data repeater 23 addresses the connected character generator 12 as a function of the timer pulse of the assigned character. The pattern signal of the character generator 12 is fed to a Para1 j el serial converter Ik and converted into a serial video signal.

The signal is then passed on to a playback device 19 via a mixer 25 and is displayed there visually. Each address stored in the group register 17 and in the cursor register 18 is read out by the LS key on the keyboard 11 and processed in the computer unit 14 and stored in a character register 26 as a character address which specifies a certain character in the character group.

A counting register 27 counts the character data numbers that are in the Character register 26 is stored. The LD key is used to Reading out the character address in the character register 26 and for the Playback of this symbol on the playback device 19. The LA button is used to delete part of the data of the played back Character from the character register 26 is used.

On the basis of the flow chart shown in Fig. K, the operation of the apparatus will be explained in detail.

In step (1), each storage group specified in the above was reset by an RS key input. The group register 17 and the cursor register 18 are set to "1" and the count register 27 is set to "0". The value (n) in group register 17 corresponds then the group (Gn) in FIG. 3.

In step (2) the character column "a, b, c, d, e, i, g, h ", which belongs to the set group (Gl), is reproduced on the playback device 19. The cursor is then on the character "a" is reproduced on the basis of the content of the cursor register 18 or displayed.

In step (3), every time the CN key is pressed the cursor is moved one step to the right. The cursor moves one character at a time right and the count value of the cursor register 18 becomes 1 to be added.

In step (4), every time the CR key is pressed the cursor is moved one letter to the left, and 1 is subtracted from the value of the cursor register 18.

In steps (5) and (6), when a desired character in the character column "a, b, c, d, e, f, g, h" on the playback device 19 is not included, the GN button or the GR button is pressed to change the group playback bring about. When the GN button is pressed once the following group of characters (G2) "i, j, k, 1, m, n, o, p "is displayed. The group register 17 is then set to "2". When the GR button is pressed once, the capital letter group (G20) "N, O, P, Q, R, X, Y, Z"

is displayed at the other end of the group display, and the group register 17 is set to "20".

In step (7), the operator repeats as appropriate Follow steps 3 to 6. The cursor is then stopped at the desired character and the LS key is used for input this symbol is pressed.

In step (8), the respective address data from the Group register 17 and the cursor register 18 read out and processed by the computer unit 14 in the CPU 13.

In step (9) the data processing in the previous Step received character address in the character register 26 set.

In step (10), 1 is added to the value of the counting register 27 and the process returns to step 2 again.

The above steps are carried out until the desired character data has been entered. The steps are terminated by pressing the RS key in step (11) is, or the steps are stopped when the count register 27 indicates an impossible entry.

The invention provides an input device for character data created in which a number of character groups to be entered in character generating devices which address assignments are received and sequentially output corresponding characters from an address as a pattern signal. The sign will be on a Playback device reproduced and using a cursor entered.
