Abstract

PURPOSE:To store printing information into a memory and make it possible to separately perform an inputting operation and a printing operation, by providing a memory for storing message data on the operations of an additional function, and provided a mode-selecting key for selecting either transition of a processing routine to an operation mode for the additional function or the return of the processing routine to a normal operation mode. CONSTITUTION:With an input from an additional function-selecting key 21, the additional function thus selected in searched to determine the nature thereof. Then, message data corresponding to the additional function thus searched is called from a memory 20, and is displayed on a display part 2. Therefore, the operator can judge whether a desired additional function to be executed is the one actually inputted, by the message data displayed on the display part 2. Based on the judgement, either the return of a processing routine to a normal operation mode or the transition of the routine to an operation mode for the selected additional function is selected by operating a mode-selecting key 4. Namely, when an error is made in an inputting operation due to an erroneous operation, the routine is returned to the normal operation mode to provide an opportunity for re-inputting.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic typewriter that stores printed content in a memory so that input operations and printing operations can be performed separately.

BACKGROUND ART In this type of apparatus, editing and printing are performed according to a predetermined processing routine, and various additional functions can be easily performed during the editing or printing process.

These additional functions refer to various editing functions and printing functions.

For example, in the editing process, it is necessary to copy or recall a specific document, and in the printing process, it is necessary to select a font.

On the other hand, in order to execute these additional functions, it is sufficient to shift the processing routine to the corresponding operation mode.

Problems to be Solved by the Invention In conventional electronic typewriters, when an instruction to perform an additional function is given, the processing routine instantly shifts to an operating mode for that purpose. Therefore, there is a drawback that an opportunity to confirm whether or not the instructed operation mode is the operation mode for the intended additional function is not provided. Therefore, if an erroneous operation is made, for example, an unintended additional function is executed without being given an opportunity to correct the error.

Means for Solving the Problems The present invention provides a memory for storing message data regarding the operation contents of additional functions, selects one of the additional functions, and stores the message data related to the selected additional function in the memory. An additional function selection key is provided which is called up and displayed on the display section, and a mode selection key is provided which selects whether to shift the processing routine to the operation mode for the additional function or to return to the normal operation mode.

When one of the additional functions to be executed is selected using the additional function selection key, the corresponding message data is displayed on the display section, giving an opportunity to judge whether or not to actually shift the operating mode.

Therefore, if the message data is related to the intended additional function and the mode selection key is used to specify that line, the additional function is executed for the first time. Therefore, an opportunity for correction is provided before the additional function is actually executed, and the inconvenience caused by erroneous operation is resolved.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 5. A display section 2 and a keyboard 3 are provided outside the main body case 1 in the form of a housing. The display section 2 consists of a liquid crystal display. The keyboard 3 includes a mode selection key 4. This mode selection key 4 is a yes key 5a.
It consists of two keys: and a non-key 5b.

Next, inside the main body case 1, a platen 7 for conveying the recording paper 6 is rotatably provided, and a carrier shaft 8 and a guide shaft 9 are arranged parallel to the platen 7. A daisy-wheel type print head 10 is attached to these carrier shaft 8 and guide shaft 9.
A carrier 11 on which is placed is slidably attached.

A tension belt 13 that is stretched around two pulleys 12 arranged near both ends of the platen 7 is fixed to the carrier 11 . However.

The print head 10 is arranged such that a character portion of a daisy wheel (not shown) faces the platen 7 at the printing position, and an ink ribbon 14 is provided between the print head 10 and the platen 7. .

Next, a CPU 15 is provided, the connection of each electrical component being shown in the block diagram of FIG. 1, and the display section 2 and the keyboard 3 are connected to this CPU 15. In addition, a paper feed motor 16 (hereinafter referred to as PF motor), a carrier motor 17 (hereinafter referred to as CA motor), a daisy motor 17 (hereinafter referred to as CA motor),
A wheel motor 18 (hereinafter referred to as a DW motor) and a hammer solenoid 19 are also connected to the CPU15. The PF motor 16 is a paper feed driver 16a.
The CA motor 17 is connected to a carrier driver 17a via
The DW motor 18 is connected to a daisy-wheel driver 18a, and the hammer solenoid 19 is connected to a hammer driver 19a. Here, the PF motor 16 serves as a drive source for the platen 7, and the CA motor 17 serves as a drive source for the carrier 11. Said DW
The motor 18 serves as a drive source for a daisy wheel (not shown) inside the print head 10. The hammer solenoid 19 serves as a drive source for a hammer solenoid (not shown) that drives a predetermined character of the daisy wheel to impact the platen 7. In addition, the above C
A memory 20 is also connected to the PU 15.

Although not shown, the contents of the memory 20 include a plurality of independent expansion memories for executable additional functions, and a message data area for the operation contents of each additional function. It is being

In such a configuration, the flow of operations will be explained based on the flowchart of FIG. 4. When the processing routine is in the normal operating mode, when a key is pressed on the keyboard 3, the input data is immediately printed on the recording paper 7 in the same manner as a normal daisy-wheel printer.

On the other hand, if the additional function selection key 21 is input during this process, the processing routine shifts to a display mode and an interrupt operation is performed. Here, the additional function selection key 21 is a key for selecting one of the executable additional functions, and does not refer to a specific key on the keyboard 3.
For example, it is configured by a combination of any two keys. Therefore, when this additional function selection key 21 is input.

A search is made to find out what the selected additional function is.

Then, message data corresponding to the searched additional function is retrieved from the memory 20.

This is displayed on the display section 2. Therefore, the operator:
Based on the message data displayed on the display section 2, it can be determined whether the additional function intended to be executed is the additional function that was actually input. Based on this judgment, the operator selects whether to return the processing routine to the normal operation mode or to shift to the operation mode of the selected additional function using the mode selection key 4. That is, if an input operation is postponed due to an erroneous operation, the operation mode is returned to the normal operation mode and an opportunity for inputting again is given.

The significance of displaying message data on the display section 2 is that it provides an opportunity for correction.

However, when 1 selects the line to return to normal operation mode, 5
The display of the message data on the display section 2 is erased, and the processing routine returns to the normal operating mode. On the other hand, when a line is selected that shifts to an additional function operation mode, the processing routine shifts to that operation mode and the additional function is executed.

When the selected additional function is executed and completed, the processing routine is returned to the normal operation mode, or
Alternatively, the mode selection key 4 can be used to select whether to terminate all operations.

Young Fruit of the Invention The present invention stores message data regarding the operation contents of additional functions in a memory, reads message data corresponding to any of the additional functions selected by an additional function selection key from the memory, and displays the message data on a display unit. However, since the mode selection key allows the user to select whether to shift the processing routine to the operation mode for the additional function or return to the normal operation mode, it is possible to change the processing routine after the message data is displayed on the display. An opportunity for correction is given before the additional function is executed, which has the effect of contributing to resolving inconveniences caused by erroneous operations.
