Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mobile copying device that reads and records images by moving one device at a time. The present invention relates to a copying apparatus having the following.

[Background of the invention]

Conventionally, this type of mobile copying device has not been proposed. For this reason, conventional copying machines used a finder system to align the position when reading, but there was no way to check the content when recording, so it was necessary to predict the content to be recorded or try it out. I had to adjust the position by mistake. Therefore, when one image is formed by multiple copies, it is nearly impossible to perform complete alignment following the previous copy.

On the other hand, as a scanner (reading device),
No. 3774, Japanese Unexamined Patent Publication No. 59-151269, etc. have been proposed, and image sensors are used there.
The image sensor is a one-dimensional line sensor, and although it can display read data, it cannot be used for positioning with respect to paper during recording.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a mobile copying apparatus that has a multifunctional display section and can solve the above-mentioned problems.

[Structure of the invention]

To this end, the present invention provides a display function that displays the entire area or part of the reading aperture at the time of reading, or all the images that have been read, and the content or editing content of part or all of the stored data at the time of recording. A display section is provided which has two or more functions of displaying a stored image including a recorded portion during recording or a recorded portion that can be displayed on the display section.

〔Example〕

Examples of the present invention will be described below. FIG. 1 is a diagram showing the appearance of a mobile copying apparatus according to one embodiment. In FIG. 1, a main switch 1 is used to turn on and off the power of the entire apparatus A. Reference numeral 2 denotes a mode changeover switch, which is used to select reading mode, editing mode, and recording mode. 3 is a start/stop switch; when turned on to start operation in the selected reading or recording mode, the device becomes operable; when turned off, it becomes inoperable (stop). becomes. Reference numeral 4 denotes a liquid crystal display device, which has a marker 4a at the center in the horizontal direction, and serves as a finder for displaying an image of the entire area or part of the reading aperture during reading, and also for displaying memory contents to be recorded, editing contents, etc. during recording. In addition, during recording, it functions to display the stored image including the recorded portion and the displayable recording portion, and also displays the status of the device, such as whether it is in recording mode or read mode, and the remaining amount of memory. It also displays the level of battery voltage drop, battery voltage drop warning, etc. Reference numeral 5 designates a group of keys for collecting data, which are normally covered by a transparent cover 6 to prevent them from being pressed inadvertently during other operations. By operating the keys in this key group 5, you can enlarge or reduce data, roll amp down to shift the image displayed on the display 4 upward or downward, image shift to shift the image on the display 4 left or right, and memory Clearing etc. can be performed.

Figure 2 shows the reading mechanism section AI and the recording mechanism section A inside the device A.
FIG. This device A is configured so that its movement is guided by front and rear running rollers 7.8, and the - roller rough is provided with a belt 9 for detecting the direction of movement and the amount of movement (distance). encoders 10 are coupled. In the reading mechanism unit AI, there is an illumination light source 12 that illuminates the surface to be read through a reading window 11 serving as a reading opening, and a two-dimensional light source 12 that illuminates the surface to be read through a reading window 11, and a two-dimensional light source that enters reflected light from the surface to be read that corresponds to the reading window 11 and reads the image. An image sensor 13 and a lens 14 for focusing an image of the surface to be read on the sensor 13 are arranged. On the other hand, in the recording mechanism section A2, a thermal head 16 that hangs downward from a recording window 15 serving as a recording opening during recording, and an ink ribbon 17 that slides into contact with the recording surface of the head 16 are arranged.

FIG. 3 is a diagram showing the internal functional blocks of device A.

18 is a binarization circuit that binarizes data from the two-dimensional image sensor 13, 19 is an oscillation circuit, and 20 is an oscillation circuit 19.
The two-dimensional image sensor 13 is driven by receiving pulses from the preset counter/gate 21 and the display RAM.
This is a drive circuit/address counter that controls 22. Further, 23 is a shift register for controlling the display RAM 22;
4 is a liquid crystal drive circuit that drives the liquid crystal display 4; 25 is a switch that is switched by mode switching;
side, and switches to side b when in recording/editing mode. 26 is a CPU that controls the whole, 27 is a preset value gate, 28
is an address counter for the image storage RAM 29; 30 is a switch similar to the switch 25; and 31 is a D'MA controller.

Next, the operation will be explained. First, the power switch 1 is turned on, and the mode changeover switch 2 is used to select a reading mode.

As a result, the illumination light source 12 is turned on, the two-dimensional image sensor 13 performs reading, and the content is displayed on the display 4.

That is, when the mode changeover switch 2 is operated to set the reading mode, the two-dimensional image sensor 13 is activated by the oscillator 19.
, are constantly driven by the drive circuit/address counter 20. The image signal from this two-dimensional image sensor 13 is applied to a preset counter/gate 21 through a binarization circuit 18. This preset counter/gate 2
1 compresses the image signal according to data given in advance from the CPU 26, and sends the obtained output to the display RAM 22 via the shift register 23. The contents of the display RAM 22 are then read out by the display liquid crystal drive circuit 24 and displayed on the liquid crystal display 4.

FIG. 4 shows the state of this reading display. As shown in (a) of the figure, the two-dimensional image sensor 13 reads a portion of the document B with a width X corresponding to the reading window 11, and this is displayed on the liquid crystal display 4 as shown in (b) of the figure. .

Next, the start/stop switch 3 is turned on to put the device into a readable state (start). and,
When the apparatus A is moved in the direction of the arrow Y and it is detected that a read timing signal has arrived from the encoder 10, one row of data on the image sensor 13 corresponding to the position of the marker 4a on the display 4 is transferred to the preset value gate 27. The image address counter 28 operates to capture the image into the image storage RAM 29. Thereafter, the above operation is repeated according to the output of the encoder 10. - After constant running, turn off the start/stop switch 3 to stop reading. Then, repeat the same operation along another line of the document.

Next, we will explain the editing mode, but before that, let's take a look at the fifth
As shown in the figure, it is assumed that one image (two images) is read over three lines with different reading starting points (■, ■, ■). In this case, at the end of reading, the image on the image storage RAM 29 is as shown in FIG. 6 (al). Here, when one line is output, as shown in FIG.
An image as shown in a) is obtained. Next, regarding the second line, since the reading start position is different from the first line, if output (recording) is performed as is, the image will be shifted. Therefore, the editing function is used to shift the image on the image storage RAM 29 before outputting. In this example, we just need to shift the image to the left.

Image shift will be explained below. In the editing mode, a portion of the image on the image storage RAM 29 is always transferred by the DMA controller 31 to the display RAM 22, and the liquid crystal display 4 displays the contents of the display RAM 22. Therefore, when you press the edit key 5a (specifically the image shift key in this case) in the key group 5, the DMA
The transfer control address of the controller 31 is CPU
26, and on the image storage RAM 29,
The portion that is different from before the key is pressed is transferred to the display RAM 22 and displayed. Therefore, by continuing this operation until the image is at the desired position and then outputting it, an image without any deviation can be obtained. This situation is shown in Figure 6 (1)).
It is shown in FIG. 7(b). In FIG. 6 (bl), the image in the second row matches the image in the first row, and the image in the second row in this state is recorded as shown in FIG. 7 (bl).
The recording start position of the second line is the same as that of the first line. By repeating the above operations, the image memory RA is finally
The image of M29 matches the image to be read shown in FIG. 5 as shown in FIG. 6 (C1), and 3
The image recorded over the rows becomes an image without deviation, as shown in FIG. 7(C).

Next, the image recording operation will be explained. When the recording mode is selected with the mode changeover switch 2, the transfer control address of the DMA controller 31 is determined by the CPU 26 so that the beginning of the stored image matches the write start position. As a result, several lines before and after the writing start position (for example, 1 to 640 F dot lines, 320 dot columns) are displayed on the liquid crystal display 4.

Therefore, after confirming the displayed contents and aligning the data so that the first column of data is at the recording position, the start/stop switch 3 is turned on.

Then, when the apparatus A is operated and a write timing signal from the encoder 10 is detected, one line of data corresponding to the marker 4a of the liquid crystal display 4 is transferred from the image storage RAM 29 to the Searle node 16 and recorded. At the same time, the transfer control address of the DMA controller 731 is rewritten, the display is scrolled, and the image to be recorded is shifted one line at a time in the direction opposite to the arrow Y direction. On the other hand, if there is no need to consider the positional relationship of the second scan, continue the above scanning.If it is necessary to consider the positional relationship of the second scan, turn off the start switch 3 and display 4. to confirm the contents of the image storage RAM 29 for the second scan, and as explained in the edit mode above, align the first column of the data for the second scan with the marker 4a by operating the edit key. From there, scanning is performed.The above situation is shown in Fig. 8(a).
, shown in (b).

C is recording paper. Note that the editing mode and recording mode operate interactively. A flowchart of the above operation in FIG. 9 is shown.

The display 4 may display the entire area or part of the reading aperture at the time of reading, or all the images that have been read, or display the content of part or all of the stored data or the edited content, etc. at the time of recording. It is possible to have a function of displaying a stored image including a recorded part during recording or a recorded part that can be displayed on a display, but only two of these functions may be provided.

〔Effect of the invention〕

As described above, according to the present invention, reading or recording can be performed extremely easily by checking the display section, and in particular, by being able to perform position alignment, etc., the recording can be performed extremely easily. It becomes easier.
