G, fourth lamp indicators 47 to 49 are connected.

Further, the keyboard 12, ROM (read only memory) 57, and RAM (random access memory) 58 are connected to the CPU 50, respectively.

The ROM 57 includes a program memory 100 that stores programs corresponding to the above-mentioned type mode, store mode, and print mode, as well as programs for controlling the operation of the entire typewriter. A pattern memory 10 in which pattern data corresponding to possible letters, numbers, and symbols are stored.
2 is provided.

On the other hand, the RAM 58 includes a margin key 11, a tab set key 25, a character spacing selection key 38, and a line spacing selection key 3.
Left and right margins, tabs, input by operations such as 7, etc.
An input buffer 7 memory 110 that temporarily stores format data such as character spacing, line @ spacing, and character data input by operating the alphabet keys 19, numeric keys 20, symbol keys 21, etc.; A display buffer memory 112 that temporarily stores data such as characters, numbers, and symbols to be displayed, and a recording buffer 1 that temporarily stores data corresponding to characters, numbers, symbols, etc. that are to be printed by the printing mechanism. A memory 114, a text memory 116 that stores a considerable amount of character data such as characters, r1 characters, symbols, etc. input manually in the store mode, and format data, and a work buffer memory that stores the set mode and functional operable state. 118 are provided.

When a mode such as type mode is set by operating the mode selection key 36 or the like, the CPU 50 lights up the second lamp indicators 39 to 42 corresponding to that mode, and A specific operable function is extracted, the typewriter is put into a state where the function can be operated, and any one of the first lamp indicators 14 to 18 corresponding to the function is lit. For example, when the print mode is set, the CPU 50 lights up the corresponding second lamp indicator 41, and
The auto mode and line-by-line functions are automatically enabled and the corresponding second lamp indicator 39 and first lamp indicator 16 are turned on.

The mode conversion process in the typewriter configured as described above will be explained.

First, when the power is turned on, it is automatically set to the initial setting state of normal mode and type mode. In this case, the particular function is not ready. Next, for example, when the line-by-line key 31 is pressed, the line-by-line function becomes operational, and the corresponding first
The lamp indicator 16 lights up. When the second mode selection key 36 is pressed in this state, the second lamp indicator 41 corresponding to the print mode lights up, and the first lamp indicator 16 corresponding to the line-by-line function automatically turns off. , and a second lamp indicator 3 corresponding to auto mode.
9 lights up. At this time, the first and second lamp indicators 1
6.39.41 is turned off and on, the line-by-line function becomes inoperable and print modes including O1-mode are set. Note that if the auto mode is not required, the mode can be converted to another mode by operating the first mode conversion key 35.

In this state, when the second mode conversion key 36 is pressed again, the second lamp indicator 41 corresponding to the print mode turns off, the second lamp 42 corresponding to the store mode turns on, and the The first lamp indicator 16 corresponding to the line-by-line function is lit, and the second lamp indicator 39 corresponding to the auto mode remains lit. At this time, the first step is similar to the above. As the second lamp indicator 16.39.41.42 turns off and on, the line-by-line function becomes operational and the store mode including the auto mode is set. Also, as in the print mode, it is also possible to delete the line-by-line function or change the auto mode.

When the second mode conversion key 36 is pressed again in this state, the second lamp indicator 42 corresponding to store mode turns off, and the second lamp indicator 39 corresponding to auto mode turns off automatically. do. At this time, the first lamp indicator 16 corresponding to the line-by-line function remains lit, but this is due to the previous type mode (Normal, Auto, Justic 1) and the function ready state. The CPU 50 performs backup control using the work buffer memory 118 of the RAM 58 that stores .

As described above, when a desired mode is selected and set, the CPLJ50 extracts other modes under that mode and states in which specific functions can be operated, enables each state to operate, and displays the corresponding display. Activate.

Furthermore, when setting the type mode, for example, if the first mode conversion key 35 is operated to set the Justify mode, the second lamp indicator 40 corresponding to the Justify mode lights up, and the line-byte mode is automatically activated. The first lamp indicator 16 corresponding to the line function and the second lamp indicator 39 corresponding to the auto mode are lit, and their respective functional operations are set.

Therefore, in the present invention, when a predetermined mode is set, the mode and function operation are determined in advance according to the standard usage condition in that mode, and the display corresponding to each function is automatically made. The user of the writer can check at a glance other modes that can be operated under the selected mode and the state in which a specific function can be operated without referring to a manual or the like.

Although a plurality of lamp indicators were used in the above embodiment, each function may be displayed on a liquid crystal display.

Further, in the above embodiment, the line-by-line function and the like are specified as specific functions by operating the function setting means, but when they are set as a mode by operating the mode setting means, for example, line-by-line mode, A corresponding display may be displayed, and a display and function corresponding to the auto function (corresponding to the auto mode in the above embodiment) may be set.

Furthermore, the present invention is not limited to the above-mentioned embodiments, and the configuration of each part can be arbitrarily changed without departing from the spirit of the present invention.

(Effects of the Invention) As exemplified in the embodiments above, the present invention is configured such that when a certain mode is selected by the mode selection means, a display corresponding to the functional operation that can be performed in that mode is displayed. To provide an excellent effect of allowing the functions of a typewriter to be used easily and effectively.
