Abstract

PURPOSE:To enable printing to be certainly performed, by a method wherein when printing on paper is being continued or is interrupted, a switch is made on and when printing on the paper is ended, the switch is made off. CONSTITUTION:When a printing data is transferred to a printer 12 after the data to be printed has been written in a line buffer, printing is started with the printer 12. At that time, whether a ribbon is exhausted or not is judged with a detection part 13. When the ribbon is exhausted, whether a selection key or not is judged (S8) by inputting a key from a keyboard 5. In the case of the selective key, the operation advances to (a) line. Successively, a line feed amount is transferred to the printer 12, and the paper is fed by a certain amount. At that time, whether the paper is exhausted or not is detected and when the paper is exhausted, the operation advances to (d) line. Further, 1 is subtracted from the number of printing lines and whether the number of printing lines is zero or not is judged. When the number of printing lines is not zero, the operation is returned to (e) line and when zero, an automatic power saving designation flag is set to automatic power saving. Thereafter, when there is no key input from the keyboard 5 within a certain time, a power source is made open.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an electronic device equipped with a printing device such as a hand-held word processor that is integrally equipped with a printer or the like.

(Prior Art) In recent years, handheld word processors (hereinafter referred to as word processors) that are integrally equipped with a printer or the like have become popular.

In this word processor, if ribbon or paper runs out during printing, the printer's printing operation is stopped and a message is displayed to inform the user of the cause of the stoppage. Further, for example, in order to suppress consumption of the built-in secondary battery, the power is automatically turned off if no key input is made within a predetermined period of time.

However, if the power is automatically turned off when the ribbon or paper runs out during printing, you may not know why printing was interrupted or how far you have printed. There is this inconvenience.

(Problems to be solved by the invention) The present invention attempts to solve the above-mentioned conventional problems.
It is an object of the present invention to provide an electronic device equipped with a printing device that can perform printing reliably.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes a switch means for turning off the power when there is no key input within a predetermined time, a ribbon detection means for detecting the ink ribbon running out, and a paper running out detection means. A paper detecting means for detecting, a display means for displaying the detection results of the ribbon detecting means and the paper detecting means, and a switch means are turned on when printing on the paper continues or is interrupted, and printing on the paper is stopped. and control means capable of controlling the switch means to turn off when the switch is turned off.

(Function) In the present invention, it is possible to control the switch means to be turned on when printing on paper is continuing or interrupted, and to be turned off when printing on paper is finished. Therefore, printing can be performed reliably.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a word processor integrated with a printer.

In the figure, the word processor is equipped with a CPU 1 that controls the operation of each component described later, a RAM 2 that stores input document data, and a ROM 3 that stores system programs, character fonts, a kana-kanji conversion dictionary, etc. It is being

In addition, word processors include keyboard interface 4,
Keyboard 5 for inputting documents, V-RA for display)
6, an LCD interface 7, an LCD 8, a floppy disk drive interface 9, a floppy disk drive 10 into which a document floppy disk for storing documents is inserted, a printer interface 11, and a printer 12 for printing documents.

Furthermore, the word processor includes a detection unit 13 that detects ribbon out or paper out, a display unit 14 that displays ribbon out or paper out, and a switch unit that turns off the power if there is no key input from the keyboard 5 within a predetermined time. 15 are provided.

Next, the operation of the word processor described above will be explained using the flowchart shown in FIG.

First, when setting a print format, the character size and character pitch are set for each line or character for an input document, and then the CPU 1 executes a printing execution routine.

Then, set the automatic power saving designation flag to not automatic power saving (Sl)L, and then set the number of lines to print for the document to be printed (Sl).
2) Do. Next, data to be printed is written to the line buffer (S3), and then, when the print data is transferred to the printer 12 (S4), the printer 12 starts printing.

At this time, the detection unit 13 determines whether or not the ribbon is broken (
S5), and if the ribbon is out, the display unit 14 displays that the ribbon is out (S6). Then, the keyboard 5 becomes ready for key input (S7).

Next, when there is a key input from the keyboard 5, it is determined whether or not it is a selection key (S8), and if it is a selection key, the process proceeds to the a line. If it is not a selection key, it is determined whether it is a cancellation key (S9), and if it is not a cancellation key, the process returns to line b and waits for key input again. In the case of the cancel key, proceed to line C.

Next, the line feed amount is transferred to the printer 12 (S10),
Paper is fed by a predetermined amount. At this time, the detection unit 13 detects whether or not the paper is out (S11), and if the paper is out, the display unit 14 displays that the paper is out (
312) to be done. Then, the process waits for a key input from the keyboard 5 (S13).

Next, when there is a key input, it is determined whether it is a selection key or not (S1
4) If the selection key is pressed (S15), it is determined whether there is paper (S15). If there is no paper, the display unit 14 again displays that the paper is out. If there is paper, proceed to line d.

Furthermore, in (S17), 1 is subtracted from the number of printed lines, and it is determined whether or not the number of printed lines is 0 (818).

Then, if the number of print lines is not 0, the line is returned to e. If the number of printed lines is 0, the automatic power saving designation flag is set to automatic power saving (S19).

After that, if there is no key input from the keyboard 5 within a predetermined time, the power is automatically turned off.

Therefore, in this embodiment, even if ribbon or paper runs out during printing, the power will not be turned off until a key is input from the keyboard 5, making it easy to check the cause of printing interruption and how far printing has been completed. Become.

[Effects of the Invention] As described above, an electronic device equipped with the printing device of the present invention can perform printing reliably.
