Abstract

PURPOSE:To realize automatic printing, in which the size and set position of recording paper are matched, by a method wherein a printer controlling means, by which sentences, figures and the like set by a format setting means are printed at the predetermined position detected by a paper size recognizing means of recording paper, is equipped. CONSTITUTION:When a paper 6 is set, a carriage is moved from left to right so as to scan the paper 9 once. The platen of a printer part acts as a reflector 8, the light reflected from which is received at all times by the light receiving part 6 of a sensor part 7 provided at the side of the carriage and the reflectance of which changes at the site that the paper 9 is present. By the change just mentioned above, a switch is turned ON, resulting in detecting the left edge of the paper 9. During further movement of the carriage, the reflectance changes at the right edge of the paper 9, resulting in turning OFF the switch so as to detect the right edge of the paper 9. By turning ON/OFF of the switch, the left and right edges of the paper and the breadth of the paper 9 is found out, resulting in recognizing the size of the paper. Further, by the distance between the positions of the left and right edges of the paper 9 and the home position of the carriage, the position of the paper 9 on the carriage is recognized. Furthermore, a controlling part sets the format of an edited plane so as to match to the size of the paper.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing device equipped with a printer.

[0002]

2. Description of the Related Art In a conventionally known word processor (character processing device), when a text is edited, a format of an edit screen is preset to a paper size to be printed before starting the edit. Further, at the time of printing, the paper was set at a predetermined position.

[0003]

In the conventionally known word processor, the format of the editing screen is always set according to the size of the printing paper before the text is edited. This is because a problem occurs if the edit format and the size of the printing paper are different. Moreover, when the printing paper is printed at the shifted position without being set at the predetermined position, the printing paper runs off the paper.

Therefore, in view of the above points, an object of the present invention is to provide a character processing device capable of automatic printing in accordance with the size and setting position of recording paper.

[0005]

In order to achieve such an object, the present invention is a character processing apparatus equipped with a printer for printing processed sentences, graphics, etc., in which a recording paper attached to the printer is used. Paper size recognition means for recognizing the size of the recording paper by detecting both ends, and format setting means for setting the format of the editing screen to match the recording paper in response to the output of the paper size recognition means, Printer control means for printing the sentences, figures, etc. set by the format setting means is provided at a predetermined position of the recording paper detected by the paper size recognition means. Further, the edited document can be enlarged or reduced according to the size of the recording paper.

[0006]

In the present invention, the sensor for recognizing the paper size is mounted on the carriage (head receiving portion) of the printer. When the paper is set in the printer, the carriage scans the paper once to detect both ends of the mounted paper and recognize the paper size and position from the width of the paper. Therefore, the format of the edit screen can be set to the same size as the print paper.
Moreover, since the position of the paper is recognized, it is possible to accurately print the position of the paper regardless of the position of the printing paper.

[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, 1 is a printer having means for printing, 2 is a recognition device (sensor) having means for detecting both ends of paper set in the printer, and recognizing size and position, 3 is an editing screen The display device 4 having means for displaying is a control device having means for controlling the size recognized by the sensor to be converted into a signal and transmitted to the display device to format the display screen to the same size.

FIG. 2 is a block diagram of the sensor 2 shown in FIG. In FIG. 2, 5 is a light emitting unit (LED), 6 is a light receiving unit, 7 is a sensor unit, 8 is a reflector, and 9 is paper.

FIG. 3 is a perspective view showing a mounting state of the sensor section 7. In FIG. 3, 10 is a head unit in the printer, and 11 is a head receiving unit (carriage).

That is, the sensor section is composed of a photoreflector type light source switch. The light of the LED reflected from the reflection plate is always detected by the light receiving section, but the reflectance changes where there is paper. Therefore, the switch is turned on by the change of the reflectance, and thereby the edge of the paper is detected.

FIG. 4 is a flow chart showing the control procedure of this embodiment. In FIG. 4, it is determined in S1 whether or not paper is set in the printer. If it is not set, the process returns to the original state, and if it is set, the process proceeds to S2. Both ends of the paper set in S2 are detected, and size position recognition is performed. In S3, the paper size and the format of the edit screen are compared. If they are the same, the process ends. In S4, the format of the edit screen is set to the same size as the print paper, and the process ends.

As described above, in the word processor according to the present embodiment, first, the paper is set in the printer before editing the text for the purpose of printing after editing. When the paper is set, the carriage begins to move from left to right so that it scans the paper once (FIG. 3).

The platen (rear plate) of the printer section is a reflecting plate, and the sensor light receiving section mounted on the side of the carriage always receives the light from the reflecting plate. Changes. Now the switch is turned on and the left edge of the paper is detected. When it moves further, the reflectance changes at the right edge of the paper, and the switch is turned off to detect the right edge of the paper.

Since the width of the paper can be known from the left end and the right end of the paper by turning the switch ON / OFF, the size of the paper can be recognized. In addition, the position of the paper is recognized based on the distance from the home position of the carriage to the detected left edge of the paper.

When the paper size is recognized, the control unit sets the format of the editing screen according to the paper size. The procedure of the control unit is executed according to the flowchart shown in FIG.

The types of paper that can be discriminated are A4, B5 and B.
4. Postcards are placed vertically and horizontally, respectively. In other words, the control unit automatically performs the format setting that the user himself / herself had done before the text editing, just by setting the paper on the printer.

As a further effect, at the time of printing, the set of paper has a position determined by the paper size (specified by ordinary silk etc.). Since the size and position are detected even if the paper is set at the position, it is possible to print at the correct position no matter where the paper is.

Next, another embodiment will be described.

Other Embodiments FIG. 5 is a flowchart showing another embodiment. In the embodiment described here, when printing the edited text,
An example of enlarging / reducing printing according to the size of the paper set in the printer is shown. The block configuration is the same as in FIG. The paper size recognition procedure is the same as in the previous embodiment.

In FIG. 5, it is determined in S11 whether or not paper is set in the printer. If it is not set, the process returns to the original state, and if it is set, the process proceeds to S12.
The size of the paper set in S12 is recognized. The recognized paper sizes are A4, B4, B5, and postcards, which are only placed vertically. The paper size recognized in S13 and the format of the edit screen are compared. If they are the same, the same-size printing process is performed in S15, and if they are different, the process proceeds to S14. Enlargement or reduction printing is performed according to the paper size to be printed in S14. When printing is finished, the flow is finished.

Next, enlargement or reduction printing processing will be described. First, the character size, character pitch, and line pitch are changed according to the magnifications in the table below.

[0023] Now, suppose that the edit screen of the word processor is A4 portrait size and the user is creating a sentence. After editing, B
When B4 paper is set in the printer to print on a document of 4 portrait size and printing is designated, the sensor recognizes the paper size as B4 portrait size. In the control device, A4
After the vertical size is expanded to B4 vertical size according to the magnification of the table, enlarged printing is started. Conversely, when B5 size paper is set in the printer and printing is designated, reduction printing from A4 size to B5 size is also started in accordance with the magnification in the table. In other words, the user can edit in a format that is easy for him to edit, without considering the print paper size. Also, after printing in A4 for the time being, make a desired original by making an enlarged copy to B4 or a reduced copy to B5 with a copier.
It has the effect of eliminating the hassle.

[0024]

As described above, according to the present invention, when a user edits a text with a word processor, the user can simply set the paper in the printer and the format is automatically set according to the printing paper. Goes up. Moreover, since the printing is performed accurately regardless of the position of the paper and the printer, it is not necessary to set the paper.

Further, it is possible to edit in a display screen which is easy to see, that is, a format of a paper size which is easy to edit, without considering printing paper.
