7. Second shift key 18, left margin set key 19, right margin set key 20, tab set key 21, tab clear key 22, tab key 2
3. Paper feed key 24 for feeding the thermal paper 6, paper return key 25 for returning the thermal paper 6, repeat key 26, code key 27, first and second mode selection switches 28, 29, insert key 30 , a delete key 31, and cursor movement keys 32a and 32b for moving a cursor 33 indicating a data input position on the display 11. Among these keys and switches, the code key 27 corresponds to the other keys, namely, various printing functions such as autocarriage return mode, light margin flash mode, centering mode, line-by-line mode, and underline mode. When operated together with any of the numeric keys 34 to 39, etc., generates code data different from the code data generated when those keys are operated alone,
This is for selecting each printing function. Line-by-line mode is a printing function for correcting and inputting pre-input data within one line, and right margin flash mode is a printing function for printing characters on each line aligned to the right margin position. The centering mode is a printing function for printing characters at the center between the left and right margins during a printing operation. Furthermore, the auto underline mode is a printing function for printing various characters and at the same time adding an underline. The first mode selection switch 28 is a two-position sliding switch for selecting one of two modes: typewriter mode and terminal mode. The terminal mode is a mode in which the typewriter is used as a data terminal device. The second mode selection switch 29 is a three-position sliding switch for selecting one of three modes: non-print mode, collection print mode, and direct print mode.
This non-print mode is a mode in which characters input by keys are displayed on the liquid crystal display 11 without printing by the thermal head 5, and collection print mode is a mode in which characters input by keys are displayed on the liquid crystal display 11. death,
This is a mode in which the data that overflows from the display 11 is sequentially printed on thermal paper 6 by the thermal head 5.Furthermore, the direct print mode is a mode in which the characters input by keys are displayed on the liquid crystal display 11 and at the same time the thermal head 5 prints the data on the thermal paper 6. This is a mode for printing on paper 6. Note that the other keys are provided in a normal typewriter, so their explanation will be omitted. Further, on the outer circumference of the liquid crystal display 11 and on the upper side of each of the keys 34 to 39, each of the numeric keys 3 is provided.
Display symbols indicating each printing function corresponding to 4 to 39 (AUTO, RMF, CTR, L/L,
XXX, ON XXX OFF). Next, an electronic circuit of a typewriter having the above-mentioned outer structure will be explained with reference to FIG. 3a. In the figure, reference numeral 41 denotes a central processing unit as a first control means, a second control means, and a determination means. Only memory 44, random access memory 45, and external interface driver/receiver 4
External interfaces 48 are connected to each other via 6. The liquid crystal display 11 is connected to the display controller 42, and both 42 and 11 constitute a display device. Further, a printing mechanism 47 is connected to the printing mechanism driver interface 43, and both 43, 4
7 constitutes a printing device. The printing mechanism 47 includes the platen 2 and the carriage 3, a driving device for driving them, a thermal head 5, and the like. The central processing unit 41 sequentially stores data corresponding to each character such as alphanumeric characters, numbers, spaces, arithmetic symbols, and other symbols input from the keyboard 10 in the random access memory 45, and also stores data corresponding to the code data thereof. The pattern data is read from the read-only memory 44 and supplied to the display controller 42 and printing mechanism driver interface 43. The display controller 42 is the central processing unit 41
Characters are displayed on the liquid crystal display 11 based on the pattern data sent from. Further, the central processing unit 41 drives the thermal head 5 of the printing mechanism 47 based on the pattern data read from the read-only memory 44, and also drives the motor etc. for driving the carriage 3 and platen 2. Further, the read-only memory 44 stores a program for controlling the overall operation of the typewriter. The random access memory 45 is provided with an input buffer 49 for temporarily storing one line of character data and function data. The connection relationship between each device and means constituting this invention will be explained with reference to FIG. 3b.
A keyboard 10, a storage device 45, and a display device 11 are connected to the control means 4 for each insert operation.
1 moves the insert position indicated by the cursor 33 and the input data lower than the insert position to the lower digit side of the display device 11, and is displayed during the insert operation after the insert position reaches the lowest position of the display device 11. Move the input data to the upper digits. Next, the processing of the present invention will be explained with reference to FIGS. 4 and 5. First, the insert routine is read out based on the operation of the insert key 30, and the insert routine starts at step S0. In this way, it is determined in step S1 whether or not data has been input with the insert mode set, and if the result is YES,
Proceed to step S2. Then, insert processing is performed in step S2. That is, in step S1, the cursor movement keys 32a, 32b
After placing the cursor 33 at a desired position, for example, the insert position shown in FIG. 5a,
For example, if you operate alpha key 12 (E),
With the cursor placed and held at the insert position, data corresponding to the character "E" is stored in the input buffer 49 between the data corresponding to the character "D" and the data corresponding to the character "1". Ru. At the same time, the data is inserted and displayed at the insert position, and the data at the insert position and the data lower than the insert position are controlled to move one digit to the lower digit side on the display 11, and the last one is displayed on the display 11. being pushed outside. Next, in step S3, it is determined whether the line-by-line mode, centering mode, or light margin flash mode is in progress, and if any of these modes is in progress, the process advances to step S4. By this step S4, the cursor 33 indicating the insert position is moved to the display 1.
1, it is determined whether or not it is in the lowest digit (right end in FIG. 5). And step S4
If the result in step S5 is NO, the cursor 33 is controlled to move one digit to the lower digit side (to the right in FIG. 5) so as to point to the previously input data "1". Therefore, cursor 3
3 always indicates the insert position on the display 11. And, for example, Figure 5c
As shown in the figure, when the character data (E to L) is inserted by repeating each step S1 to S5 described above, and the result in step S4 becomes YES,
Proceeding to step S6, the input data above the insert position is controlled to move by one digit toward the upper digit (to the left in FIG. 5). The cursor 33 is then held at the least significant digit. In this way, since the insert position and insert data are always displayed on the display 11, they can be easily confirmed. Incidentally, the display data on the display 11 is moved in step S6, and accordingly, when the data of the least significant digit reaches and exceeds the write margin position, a buzzer indicating that insertion is not possible is activated. Effects of the Invention As detailed above, the present invention moves the insert position and the input data lower than the insert position to the lower digit side of the display device for each insert operation, and moves the insert position to a predetermined position on the lowest side of the display device. During insert operation after reaching the insert position, the displayed input data is controlled to move sequentially to the higher digits, thereby maximizing the display of the inserted data in relation to the displays before and after the insert position. This allows the data to be easily viewed even on a display device that displays data shorter than one line, and when inserting continuously, the data at the beginning of the data to be inserted can be Since the input can be made from the cursor, the insert operation becomes convenient.
