Description

[Detailed description of the invention]

[Technical Field] The present invention includes a first [-] key that sequentially displays data input from a keyboard on a display device, and a first [-] key that causes the data displayed by the first [-] key to be shifted out from the display device. Regarding the electronic typewriter, in particular, the above-mentioned 3T: :-6, which relates to the processing of the f-t which has already been input from the keyboard when the mode is changed between one mode and the other. [Object of the Invention] As mentioned above, in a typewriter having the first mode in which only the display device is operated, data are inputted sequentially from the keyboard on the first t-doard, and the It may be necessary to print only the final predetermined portion of the data. For example, in an electronic typewriter that has a poetry function, it is unnecessary to print out the calculation formula, and there are cases where it is desired to print only the result of the performance. In such a case, first, the first mote is set, an arithmetic expression is input, and only the arithmetic result is displayed on the display device by operating the equal key tv. Next, the mode is switched to the second mode or the third mode, and only the results of the respective calculations are printed on the printing paper. It is conceivable that the number of characters that can be printed between the position of the print head and the line 1 to margin is large. If you want to print the same number of characters in the 99th Song Dynasty (J), you must compare the number of characters that can be printed with the number of data you want to print.The purpose of the present invention is to eliminate the above drawbacks In order to prevent this, there are 6 Cs in order to provide an easy-to-use electronic typewriter.

In addition, if the above judgment is J3 and a key other than the line feed key 6 is pressed manually, after executing the alarm process in the same way as the operation described above, it is determined whether or not the line feed key 6 has been pressed again, and according to the operation described above. Processing. When the mode selector switch 18 is switched from the third mode to the first mode, the control circuit 3G sets the flag corresponding to the first mode, and then sets the flag written in the buffer memory 36a. The process moves to the start where all the code data is erased and the characters etc. displayed on the display device 21 are erased. Furthermore, switch the mode selector switch 1 (3) from the third mode to the second mode.
When switching to the second mode, the control circuit 36 sets a flag corresponding to the second mode and erases all the stored data in the buffer memory 368 in the same manner as described above. The characters displayed on the display device 21 are erased and the process moves to the start. (Effect of the invention) Hereinafter, as explained in 1, the present invention tJ1, a large number of characters -1-
1, 1 for numbers, function keys including line feed keys, etc. are arranged, and the keyboard outputs the 11C> code for each operated key, and the keyboard outputs -1-to data manually input by the keyboard. Based on the input data, such as a control device that outputs people's information to a display device or a printing device,
It is equipped with a display device that displays numbers, etc., and a printing device that prints letters, numbers, etc. that correspond to the keys operated based on the input data.
The control device has a first mode in which data input through the keyboard is sequentially displayed on the display H position, and shifts the gamma data displayed in the first mode from the display device. Switch between the second [- mode, in which the data is printed on the print paper in the order in which the data is entered, and the third mode, in which the data entered manually from the keyboard is displayed and printed on the print paper at the same time. The code data should be displayed as soon as possible, and every time the code data is entered, it will be updated.
i'+rt rewriting 111-1; a data counter that is L-[*]; a write margin storage means that stores a write margin position; means for comparing the contents of the data counter and the contents of the write margin register 10 when switching to the first mode, and blinking and displaying data overflowing from the write margin on the display device; 11. Switch to the second mode or third mode. : By avoiding blinking display of data that cannot be printed in the same printing line, the operator can understand at a glance the state of human input of the data. It is an offering.
