Abstract

PURPOSE:To true up print start positions of individual lines at the line feed time by providing one or more editing functions of expansion, reduction, roll up/down image shift, and line end processing. CONSTITUTION:At the time of printing reaches a line end position inputted at the input time after the start of printing, a line end display part 4 is lit, and printing is stopped then. Printing is not performed thereafter though a device is moved. If a start/stop switch 3 is depressed at this time, the line end is detected, and data of the next line can be printed. Then, the line feed operation of the device is performed to start printing the next line.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mobile recording device equipped with an editing function.

[Prior art]

As prior art, methods such as those shown in Japanese Patent Application Laid-open No. 56-33774 and Japanese Patent Application Laid-Open No. 59-151269 have been proposed, but in both cases, several lines before and after the line being read are displayed. The former uses light-emitting elements for its display, and the latter uses liquid crystal.

As described above, the conventional device displays the information being read by the reading device, and is not used for editing functions. There is also no image editing function. Furthermore, none of the conventional mobile reading devices has an editing function.

However, with a mobile reader, if it is not clear which part of the stored image data to write out when recording, it is not easy to use, and when outputting an image spanning multiple lines, the printing start position It is extremely difficult to align the Furthermore, it is impossible to perform operations such as canting unnecessary parts (for example, blank spaces, etc.) of stored image data.

[Purpose of the invention]

An object of the present invention is to make it possible to call up image data in an arbitrary memory location and set it at the print start position when recording, and to make it possible to align the print start positions of each line at the time of a line break. Alternatively, data can be edited with high precision by making it possible to delete unnecessary parts such as spaces at the beginning of the part to be printed, and/or by displaying the enlargement or reduction of the stored image data. and/or to prompt a line feed after one line of data has been recorded, thereby aligning the output positions of data recording over a plurality of lines.

[Structure of the invention]

To this end, in the present invention, a mobile recording apparatus is configured to include at least one editing function among enlargement/reduction, roll amp/down, image shift, and line end processing.

〔Example〕

Examples of the present invention will be described below. In this embodiment, a case where the present invention is applied to a mobile copying apparatus will be described.

The entire mobile copying apparatus A is constructed as shown in FIG. 1, and has an operating section AI formed on its upper surface. A2 is a running roller provided at the front and rear of the bottom surface in the direction of movement, and the rotation of one of these rollers is detected to obtain a synchronization signal for reading and recording. There are three system states (modes) of this apparatus A: input mode (reading mode), output mode (recording mode), and editing mode. A mode state transition diagram of this system is shown in FIG.

FIG. 3 is a diagram showing details of the operation section A1. 1 is a power switch, 2 is a mode switch for mode (equipment status) selection, 3 is a start/stop switch, 4 is a line end display section consisting of an LED, and 5 is for performing left/right shift, roll up, roll down, etc. Edit key, 6 is magnification initialization switch, 7 is zoom down switch,
8 is a zoom up (enlargement) switch, 9a is a horizontal zoom on/off switch, 9b is a vertical zoom on/off switch, 10 is a status display section consisting of an LCD, 11 is an LCD
12 is a roll position display section consisting of an LCD; 13 is a memory usage display section showing the amount of data stored in the memory;
Reference numeral 14 denotes an image display panel consisting of an LCD, and 14 a zoom display (magnification display) panel consisting of an LCD that indicates the vertical and horizontal zoom magnifications (the number of data dots per one display pixel number).

In the input mode, the line end display section 4 lights up when the start/stop switch 3 is pressed after reading one line, and when the start/stop switch 3 is pressed again at the start position of the next line. Clarify with. Furthermore, in the editing/output mode, the light is turned on when the image reaches the end of the line, indicating that the scanning device A has reached the line break point in both input and output cases.

The edit key 5 is used to read out any part of the image data stored in the memory in the device A. Pressing the key 5a moves the key up, pressing the key 5b moves the key down. Press 5c to move left, press key 5d to move right,
Each image data is shifted. Note that the image data being accessed is displayed on the image display panel 13 within a certain range.

Magnification initialization switch 6, zoom down switch 7, zoom up switch 8, horizontal zoom on/off switch 9a
, and the vertical zoom on/off switch 9b are switches for zoom control, and in particular, the magnification initialization switch 6 is for adjusting the magnification to a preset value.

Further, the horizontal zoom on/off switch 9a and the vertical zoom on/off switch 9b are switches for enabling/disabling the zoom action in the vertical direction and the horizontal direction independently.

The status display section 10 displays the status of the device A, and the display contents are as follows. Note that these disappear when the power is turned off.

ON: Displayed when the power switch is turned on.

RE^0...Displayed when in input mode.

WRITE...Displayed when in edit/output mode.

READY...Displayed when the device is ready.

BtlSY...Displayed when the device is busy.

FRILL...A table is displayed when the memory is full of data.

LOW BATTERY...Displayed when the built-in battery voltage is low.

The roll position display section 12 displays where the image displayed on the image display panel l3 is located with respect to the entire length.

The image display panel 13 described above is a graph ink display section, and as described above, displays a part of the image data, and a center line 13a indicating the position of the recording head is displayed in the center part. .

Next, a typical procedure for using this device A will be described, and then the editing mode, which is the main point of the present invention, will be described in detail.

First, turn on the power switch 1 of device A, then press the mode switch 2, and while looking at the status display section 10,
l? EADJ, that is, select the input mode. Thereafter, the device A is placed on the document, the start/stop switch 3 is pressed, and then the device A is moved and scanned to start reading the document. When scanning a document over multiple lines (multiple times), the start/stop switch 3 is pressed at the end of each line, and the same switch 3 is pressed again at the beginning of the next line to repeat the scanning. When all the readings are completed, press the mode switch 2 so that rWRITHJ is displayed on the status display section 10.

This will select the output/edit mode. At this point, after completing the necessary editing work such as enlarging, reducing, shifting, etc., which will be described later, press the start/stop switch 3 to enter the output mode, so if you place it on the recording paper and move it,
Printing is performed when the printing timing comes during scanning.

Note that when printing is not being performed, the printer automatically enters the editing mode and can perform editing work.

In the editing mode, pressing the mode switch 2 allows mode selection, and in this case, the input mode can be selected. The above usage procedure is shown in the flowchart of FIG.

Next, details of the editing function will be explained. FIG. 5 is a state transition diagram of this editing mode. Here, eight functions are supported. Each of these functions will be explained below.

(1) Zoom function (enlargement/reduction) For example, when the zoom up switch 8 is pressed, the horizontal
When the vertical zoom on/off switches 9a and 9b are turned on, one step of horizontal or vertical enlargement is performed.

To explain the enlargement method, first, the number of display pixels of the image display panel 13 is assumed to be M (vertical) x N (horizontal).

Next, image data associated with one pixel of the image display panel 13 is assumed to be m dots in height x n dots in width. This indicates that mxn image data is multiple-projected onto one pixel of the display panel 13. In this example, M
= 64, N = 40, pixel pitch -0.5 fins, and m = 8 and n = 4 in the standard state. In this case, 512 x 160 data dots are displayed on the display panel 13.
displayed at once. In general, (Mxm)X (Nx
n) Data dots are displayed on the display panel 13.

Now, when zoomed up, m is decreased by 1 when the vertical switch 9b is on, and n is decreased by 1 when the horizontal switch 9a is on. This reduces the number of data dots per display pixel, resulting in an enlarged display.

The minimum value of m and n is 1, and values below this value are not taken.

A flowchart for the above zoom-up is shown in FIG. Zooming down can be done in the same way. In this case, the constraints on m and n are m≦(number of vertical dots in input) and n≦(number of horizontal dots in input). A flow chart for this zoom down is shown in FIG.

If the magnification initialization switch 6 is pressed during the above operation, m and n are returned to the preset values (m=8, n=4) and initialized. This makes it possible to easily obtain a standard image display.

This zoom function is important in mobile copying machines. This is because, at the current technological level, it is almost impossible to realize a high-density liquid crystal display with the same pixel density as the read pixel density. This requires a very large display panel, and conversely, a display panel of appropriate size (a display panel with a width approximately equal to the scanning width) can display only a small portion of the image data. This is because it cannot be done.

Now, when you are trying to perform an aggregation process, you need to look at the entire image and at the same time take a good look at the details.

For this purpose, it is optimal to display the entire image at a high resolution, but for the reasons described above, this is practically impossible with the apparatus targeted by this embodiment.

Having a zoom feature would solve this problem. That is,
By lowering the display magnification, you can get a better overview of the image, and by increasing the magnification, you can see the details of the image with high precision, as if you were looking through a magnifying glass.

Of course, when the image is enlarged, only a portion of the image is displayed as described above, but any part of the image can be viewed using the roll up/down and image shift functions described below.

On the other hand, when looking at the entire image in a reduced size, the accuracy of the display relative to the original image decreases, but this is similar to how when looking at a distant image, it appears to have passed through a spatial low-pass filter. It is an excellent intuitive man-machine interface.

(2) Roll amp down function For example, when the roll up switch 5a is pressed, the image on the display panel 13 is shifted upward by one pixel of the display panel 13, that is, by m dots of image data. do. This is shown in FIG. In FIG. 8, 13b indicates one column (M pixels) of the image display panel 13, and b=a+m. Further, if the roll-up switch 5a is kept pressed, the image shifts continuously at high speed. FIG. 9 shows a flowchart regarding this roll amplifier. The same applies to roll-down, a flowchart of which is shown in FIG.

In addition, a roll position display section 12 is provided to indicate the current display position, and this displays the ratio of a/β from the top when the vertical doso +-i for one image take line is p. An indicator 12a is displayed there to indicate the position of the scroll window. This is rewritten along with the manual scroll key to display the latest position.

(3) Image shift function For example, if the shift button 5C is pressed, the data on the display panel 13 is shifted to the left by one pixel of the display panel 13, that is, by n dots of image data. This is shown in FIG. In Figure 11, 1
3c indicates one line of the image display panel 13, b=a+
n.

The high speed operation is similar to the roll up/down function. The above flowchart is shown in FIG. The same applies to the shift switch 5d.

A flowchart of the right shift in this case is shown in FIG.

This image shift function can be used to adjust the print start position. This function allows you to easily align the starting positions of multiple lines of print.

Conventionally, when reading an image, great care is taken to align the readout start position of each line, and when writing, the same care is taken to align the start position of each line (i.e., the cent position of the device relative to the recording paper). It was necessary to match. Furthermore, the image position always deviates slightly in each row due to the cent error.

In this embodiment, after one line has been printed (the end of the line is detected by the -CPU in memory, and printing ends automatically. After one line of data is finished, a blank is output.)
The device must be reset, that is, a line feed is performed, and printing is started again. At the time of this line feed, the image data to be printed can be easily aligned with the print start position. Normally, when reading, the reading start position of each line is uneven, so the image data corresponding to each line is also uneven, but the image shift function is used to align the printing start position.

This method is extremely convenient in actual use, even though the installation accuracy of the device is very rough during reading and writing (and the printing positions are neatly aligned).In addition, this mechanism is unnecessary when printing. It can also be used to skip the unnecessary parts. In this case, you can omit the unnecessary parts by simply shifting them in the same way as before. This is especially useful for image data. This is useful when there is a long blank section.

(4) Memory Clear Normally, input data is accumulated without being cleared. This makes it possible to output the same image many times, that is, to output the same image multiple times, and it is also possible to effectively utilize the results collection function. However, when the memory becomes full, erasing becomes necessary.

In this embodiment, when the start/stop switch 3 and mode switch 2 are pressed simultaneously for a predetermined period of time (for example, 1 second), the memory is cleared, and data can be easily cleared in this way. Can be erased.

Note that when the memory becomes full, input is interrupted and a message "memory full rFULLJ" is displayed, but if the start/stop switch 3 is pressed at this point, data will be forcibly written from the beginning of the memory. In this case, data already stored in the corresponding memory location is erased.

As a result, even if the memory becomes full while performing continuous input from an intermediate location in the memory, it is possible to continue inputting more data without erasing the data input so far. There is a great advantage that all data can be stored normally. However, as a matter of course, it is impossible to input an amount that exceeds the memory size at once.

(5) Line end processing Conventionally, no particular consideration was given to line ends, so input was simply interrupted at a line break or data end position, and when input resumed next time, data had already been stored. It was continuous with what was shown. As a result, the data will naturally be continuous when outputting, so in order to successfully stop printing at the line break position,
The only option available was for the operator to move the device while carefully observing the printed image. However, with this method, no matter how careful he was, it was extremely difficult to stop the print exactly at the desired position. Also, it was almost impossible to align the print position after a line break.

Therefore, in this process, if there are multiple lines of data in memory and the device continues to be moved even though one line of data has been output when outputting, the next The purpose is to prevent row data from being output, and to align the output positions of data across multiple rows.

Next, the operation will be explained. First, printing is started, and after the start, when the line end position input at the time of input is reached, the line end display section 4 lights up, and subsequent printing is stopped. After this, printing will no longer be performed even if the device is moved. When the start/stop switch 3 is pressed at this point, line end detection is performed and the next line of data can be printed. Then, perform a line feed operation on the device and start printing the next line. This is shown in FIG. 14 as a flowchart that matches the print timing and output.

Note that the above embodiments are applied to a copying device that can input and output text and image data; however,
It goes without saying that the present invention can be similarly applied to a single recording device that records data such as an image that has been previously input by another reading device or another machine and is imprinted or transferred thereto.

〔Effect of the invention〕

As explained above, according to the present invention, since an editing function is provided, it becomes extremely convenient to record images and characters using a mobile recording device. In particular, by making it possible to call up image data at any position during recording and set it at the printing start position, it is possible to align the printing start positions of each line at the time of line feed. It is also possible to delete unnecessary data portions such as leading blanks from the portion to be printed. Furthermore, the stored image data can be enlarged,
A reduced display becomes possible, which is possible by editing the data with high precision. Furthermore, it is also possible to align the output positions of data recording over multiple lines by prompting a line feed after recording one line of data.
