Among these keys and switches, the code key 27 is used to control other keys, namely auto carriage return mode, line right alignment printing mode (hereinafter referred to as right 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. corresponding to the various printing functions of the mode, the code data generated is 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 that prints pre-input data line by line, and right margin flash mode is a printing function that aligns the last character of each line with the right margin position. The centering mode is a printing function that prints characters in the center between the left and right margins during printing. Furthermore, the auto underline mode is a printing function for printing various characters and at the same time adding an underline.
Note that the code key 27 and the number keys 37 for line-by-line mode (hereinafter referred to as L/L keys 37) constitute a part of the memory printing means in this embodiment, and the code key 27 and the write Numeric keys 35 for margin flash mode
(hereinafter referred to as the RMF key 35) constitutes the line right alignment printing means in this embodiment. 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 constitutes a part of the memory printing means in this embodiment, and when the switch 29 is switched to correspond to the CP symbol, the key-input characters etc. are displayed on the liquid crystal display 11. A collection print mode is set in which the data is displayed and temporarily stored in an input buffer memory 49 (to be described later), and data overflowing from the display 11 and the input buffer memory 49 is sequentially printed on the thermal paper 6 by the thermal head 5. The second mode selection switch 29 also selects a non-print mode in which characters entered by the key are displayed on the display 11 without printing by the thermal head 5, and a non-print mode in which characters entered by the key are displayed on the display 11. At the same time, a direct print mode in which the thermal head 5 prints on the thermal paper 6 can also be selected. 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 the upper part of each of the keys 34 to 39, display symbols (AUTO, RMF, CTR, L/L,
XXXON, XXXOFF ) are written, and a plurality of guidances 40 are arranged on the display 11 in correspondence with these display symbols. Next, an electronic circuit of a typewriter having the above-mentioned outer structure will be explained with reference to FIG. In the figure, reference numeral 41 denotes a central processing unit, and the keyboard 10 is connected to the central processing unit via a keyboard driver 48.
In addition, a display controller 42, a printing mechanism driver interface 43, a read-only memory 44, a random access memory 45,
and an external interface driver/receiver 46 are connected, respectively. 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. 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 input from the keyboard 10, such as alphanumeric characters, numbers, spaces, arithmetic signals, and other symbols, in a random access memory 45, and also stores data corresponding to the code data. Pattern data is continuously output from read-only memory 44 and supplied to display controller 42 and print 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. Random access memory 45 is connected to keyboard 10
The input buffer memory 49 is provided to temporarily store data input from the input buffer. When a certain amount of data is input to the input buffer memory 49 when the collection print mode is set by switching the second mode selection switch 29, or when the code key 27 and the L/L key 37 When the print start signal is input when the line-by-line mode is set by the simultaneous operation of Thermal head 5 of mechanism 47

When the RMF key 35 is operated at the same time and the light margin flash mode is selected,
Carriage return key 16 or tab key 23
When the print opening signal is input by the operation of , the central processing unit 41 registers both margin position registers 51
Based on the calculation results of each data in 52 and counter 53, the last input data of input buffer memory 49 is printed at the right margin position. In the above configuration, processing related to the present invention will be explained next with reference to FIG. When the power is turned on in step S0, the carriage 3 is moved to the left margin position and the display controller 42, random access memory 45, etc. are initialized in step S1.
Then, in step S2, the display 11
is kept hidden. Next, step S3
After the main routine executes the printing process of the input data, etc., it is determined in step S4 whether or not various keys have been operated, and if the result is NO, the key scan is repeated. If the result is YES, the process advances to step S5, and it is determined in step S4 whether the RMF key 35 for setting the light margin flash mode has been operated together with the code key 27. The result is NO
If so, proceed to step S6 and
Separate processing is performed corresponding to the other keys operated in S4. Also, in step S4,
If the RMF key 35 is operated together with the code key 27 and the determination result in step S5 is YES, the process advances to the next step S7. In step S7, it is checked whether the light margin flash mode has already been entered when the RMF key 35 and code key 27 are set in step S4. If the light margin flash mode has already been entered at this time, that is, if the RMF key 35 has been pressed twice, the confirmation result is YES, and the process proceeds to step S8.
The process proceeds to step S9, where it is determined whether there is data in the input buffer memory 49. If NO, the process immediately returns to step S2, and if YES, the light margin flash set by the first RMF key 35 operation is executed in step S9. The mode is canceled and the process returns to step S2. Furthermore, if the light margin flash mode has not been entered before operating the RMF key 35 or the like, that is, if the light margin flash mode is newly selected this time, step S7
Since the determination result in is NO, the step
Proceeding to S10, printing is executed by the thermal head 5 of the printing mechanism 47 based on the data stored in the input buffer memory 49, and then step
In S11, a flag for light margin flushing is set. In this way, when the light margin flash mode is set in this electronic typewriter, the guidance 40 instructing the RMF display signal on the liquid crystal display 11 is displayed, indicating that the light margin flash printing operation is possible. shown. After certain character data is written into the input buffer memory 49 by operating the alphanumeric keys 12 or numeric keys 13 on the keyboard 10, when the carriage return key 16 or the tab key 23 is operated, the central processing unit 41, the carriage 3 is set based on the data of the counter 53 and the left and right margin position registers 51, 52.
The number of digits to be moved [(right margin position) - (current thermal head position) - (number of data)] is calculated, and the carriage 3 moves the number of digits toward the right margin, and the thermal head 5 moves the number of digits toward the right margin. Flash printing is executed. Therefore, by doing this, even if the input buffer memory 49 contains data in advance, if the characters to be line-aligned in the right margin are within the number of digits that can be input in that line, all the preceding data will be printed. After that, you can immediately set the light margin flash mode. Therefore, there is no need to operate the backspace key 15 or the delete key 31 to erase data in the input buffer 49 and return the thermal head 5 to the left margin. Effects of the Invention As detailed above, according to the present invention, when the line right alignment output means is selected during the operation of the memory output means, all the data stored in the input buffer is transferred to the output medium by the output control means. After outputting in a visible state, you can set the line right alignment output mode that enables the line right alignment output means, so even if the input buffer contains data in advance, there is no need to erase that data. This has the excellent effect of making it easier to create documents.
