Abstract

PURPOSE:To set up the position of a margin according to the position of a recording medium by simple operations by providing a controller by which to set up the position of other margin according to a given position of the recording medium when any one of left and right-handed margin positions is input and set. CONSTITUTION:A recording paper P is set on a platen 1 by matching the center line of the recording paper P with the central position of a carriage 2, and then the left margin key 10 is pushed down by moving the carriage 2 to the left margin position. The left margin position is put in a controller 22 and stored in the pointer 41 of a memory device 24. In the controller 22, the value of the left margin position is deducted from the value of the central position stored in the pointer 43, the value so obtained is added to the value of the central position to calculate the right margin position, and the right margin position is stored in the pointer 42. The right margin can thus be set up thereby.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a recording apparatus, and more particularly to a recording apparatus in which recording is performed by scanning a recording means such as an electronic typewriter.

[Prior Art] Conventionally, devices such as electronic typewriters and wire dot printers are known that perform recording on a recording medium with a desired margin by electronic control.

In this type of apparatus, the recording range, that is, the left and right margins are set mainly by setting the scanning range of a carriage equipped with a recording mechanism. This margin set is set prior to recording according to the size of the recording medium, and in this case, it is preferable to set the margins so that equal margins remain on the left and right sides of the recording medium.

Electronic typewriters are configured to use a scale placed along the platen, etc., to count the number of spaces or set margins at predetermined positions depending on the recording paper size. The work is quite tedious. Particularly in work situations where the recording paper size is not constant, this margin setting operation takes a considerable amount of time, making it difficult to improve work efficiency.

[Purpose] The present invention has been made in view of the above points, and an object of the present invention is to provide an efficient recording device that has a simple and inexpensive structure and can set a margin according to the recording medium with a simple operation. shall be.

[Example] The present invention will be described in detail below based on an example shown in one drawing.

FIG. 1 schematically shows the structure of an electronic typewriter as an example of a recording device employing the present invention.

In FIG. 1, the reference numeral 2 is a carriage equipped with a printing mechanism using a daisy wheel or the like, and this carriage 2 scans a guide rail 31 arranged along the platen 1 in the left-right direction in the figure. Platen 1
Recording is performed on recording paper wrapped in the The movement range of the carriage 2 in the left-right direction is mechanically restricted from the left end 4 to the right end 5, and therefore the maximum recording width is within this range.

A keyboard for various operations is provided in front of these printing mechanisms. The keyboard consists of a key group 6 (detailed illustrations are omitted) consisting of well-known letters, numbers, etc. keys, a space key 7, a backspace key 8, a carriage return key 9, and left and right margins provided on the right side of these keys. It consists of a left margin key lO1 and a right margin key 11 for setting.

Further, on the left side of the keyboard, there is provided a controller 12 for performing various controls by pressing in combination with the keys listed below.

Further, a paper port 15 is provided on the platen 1. A paper guide 16 is provided on the paper support 15 so as to be slidable along a scale 17. The scale 17 has graduations corresponding to the size of the recording paper, and the paper guide 16 is adjusted to the position corresponding to the size of the recording paper used, and the left end of the recording paper is aligned with the paper guide 16 and loaded onto the platen L. When this is done, the center line of the recording paper is aligned with the center position of the operating range of the carriage 2 indicated by the two-dot chain line A-B.

Next, FIG. 2 shows a block diagram of the configuration of the control circuit of the electronic typewriter. 2 is designated by the reference numeral 21, and operation input from the keyboard is inputted via a predetermined input circuit to a control device 22 composed of a microcomputer or the like, where predetermined processing is performed. Then, according to the operation input, the printing mechanism section 23 consisting of the platen 1, carriage 2, etc. is driven to perform printing.

Connected to the control device 22 is a device 24 comprised of a random access memory and the like for storing programs for various controls to be described later, print data, and the like. The storage device 24 includes a pointer 41 for control to be described later.
46 is set in a predetermined storage area. this house,
Pointer 4l is for storing the left margin position,
Pointer 42 is also for storing the right margin position. Further, a pointer 43 is used to store the central position of the carriage 2, which is indicated by a two-dot chain line in FIG. 1, and a pointer 44 is a pointer that indicates the current position of the carriage 2.

Next, the operation of the above configuration will be explained in detail with reference to FIGS. 3 and 4.

Here, as shown in FIG. 3, it is assumed that printing is performed with equal left and right margins left on the recording paper P.

That is, printing is performed so that the distance between the left end LE of the recording paper P and the left margin position is equal to the distance between the right end RE and the right margin position. In FIG. 3, printed lines are simply shown by solid lines.

Margin Sen 1 for performing such recording is performed according to the procedure shown in the flowchart of FIG.

Prior to the flow shown in FIG. 4, the operator uses the paper guide l6 of the paper support 15 and the scale 17 to align the center line of the recording paper P with the center position of the carriage 2, and then press the platen 1 onto the platen 1. 1. Keep it.

Subsequently, in step Sl in FIG. 4, the carriage 2 is moved using the space key 7 or the pack space key 8 to align it with the left margin position in FIG. 3. That is, the carriage 2 is moved to the desired print line start position. And here, similarly to the known left margin key 10
Set the left margin by pressing . This causes the left margin position to be the carriage position of the controller 2.
2, and this value is stored in the pointer 41 of the storage device 24.

After the left margin is set in this way, the control device 22 moves the pointer 4 of the storage device 24 to step S2.
The value of the left margin position stored in the pointer 41 and set in step S1 is subtracted from the value of the scanning center position stored in 3, that is, the center position of the carriage 2.

Subsequently, in step S3, the value obtained in step S2 is added to the value at the center position within the pointer 43 to calculate the right margin position, and this value is stored in the pointer 42 in step S4. In this way, the right margin position RMG in FIG. 3 is calculated and stored in the pointer 42.

Thereafter, the printing mechanism 23 is controlled by the control device 22 in accordance with the input from the keyboard using the left and right margin positions stored in the pointers 41 and 42 in the same manner as in the conventional method, and printing is performed on the recording paper P''-. will be carried out.

Load the recording paper by aligning the center of the recording paper with the center of the scanning position as described below, and then set only the left margin using the same method as known, to create equal margins on the left and right sides of the recording paper. The right margin is automatically set so that . Furthermore, in the configuration shown in "-", it is also possible to manually set the right margin.

Similar to the left margin key 10, if the right margin key 11 is pressed while aligning the gear 9 f 92 position, the right margin will be set there, and this value will be stored in the pointer 42.
Recording with special margins can also be performed by operations that are no different from conventional methods.

Furthermore, since the present invention can be implemented with only a few changes in hardware and software, it helps reduce the cost of the device.

Although the above embodiments have been described using an electronic typewriter as an example, the present invention can of course be applied to other types of recording devices. Further, in the above embodiment, an example was shown in which the right margin was set after the left margin was set, but in the case of a typewriter such as Arabic Edict, it is also possible to set the right margin from the right.

[Effects] As is clear from the explanation below, according to the present invention, there is provided a means for loading a recording medium at a predetermined position for recording scanning, a means for inputting and setting a plurality of margin positions, and a means for inputting and setting a plurality of margin positions. Since the configuration includes a control means that sets other margin positions according to the predetermined position of the recording medium when one of the positions is input and set, the center of the recording paper can be set with a simple operation. It is possible to provide an excellent recording device that is simple, inexpensive, and can set margins.
