Description

Description: TECHNICAL FIELD The present invention relates to a movable copying apparatus which is moved so as to read or record an image, and more particularly, to a display unit having a multi-function. Copy machine.

[Background of the Invention]

Heretofore, this type of mobile copying apparatus has not been proposed. For this reason, in the conventional copying apparatus, the finder system was used to perform the alignment at the time of reading, but since there was no means for confirming the content at the time of recording, it was possible to predict the content to be recorded or to try it. I had to erroneously perform the alignment. Therefore, when one image is to be formed by copying a plurality of times, it is almost impossible to complete the alignment following the previous copying.

On the other hand, as a scanner (reading device), JP-A-56-3377
No. 4, JP-A-59-151269 and the like have been proposed, and an image sensor is used therein, but the image sensor is a one-dimensional line sensor and can display read data. However, it could not be used for alignment with the paper at the time of recording.

[Object of the Invention]

It is an object of the present invention to provide a mobile copying apparatus which has a multi-function display section and can solve the above-mentioned problems.

[Structure of Invention]

To this end, the present invention provides a two-dimensional image sensor that reads an image in the area of the reading opening and a memory that sequentially stores image data of one specific line of the image read by the two-dimensional image sensor by moving the entire device. And a recording head for sequentially recording images stored in the memory by a moving operation of the entire apparatus, and a display section having a marker at a predetermined position, wherein the display section is provided at the time of reading. A display function for displaying the image of the reading opening and indicating the data position stored in the memory by the marker, the stored image during recording, or the image to be recorded among the stored images is displayed. The marker has a display function of displaying and indicating the data position recorded by the recording head.

A marker 4a is attached to the center in the longitudinal direction, and is used as a finder for displaying the entire area or a part of the image of the reading opening portion during reading, and for displaying memory contents and editing contents to be recorded during recording, and further recording. In addition to functioning as a display of a stored image including a recording portion and a displayable recording portion, the state of the device, for example, distinguishing between the recording mode and the reading mode, the degree of remaining memory, the battery low voltage warning Etc. are also displayed. A key group 5 for data editing is normally covered with a transparent cover 6 so as not to be inadvertently pressed during other operations. By operating the keys of the key group 5, the data is enlarged or reduced, and the image displayed on the display 4 is rolled up or down.
It is possible to perform down, image shift for shifting the image on the display 4 to the left and right, memory clear, and the like.

FIG. 2 is a schematic view of the reading mechanism unit A1 and the recording mechanism unit A2 inside the apparatus A. This device A is configured such that its movement is guided by front and rear traveling rollers 7 and 8, and one of the rollers 7 detects a moving direction and a moving amount (distance) via a belt 9. Encoder 10 is coupled. In the reading mechanism unit A1, an illumination light source 12 that illuminates the surface to be read from a reading window 11 as a reading opening.
A two-dimensional image sensor 13 for reading reflected light from a surface to be read corresponding to the reading window 11 and a lens for forming an image on the surface to be read on the sensor 13.
14 are arranged. On the other hand, in the recording mechanism section A2,
At the time of recording, a thermal head 16 hanging downward from a recording window 15 serving as a recording opening, and an ink ribbon 17 slidingly contacting the recording surface of the head 16 are arranged.

FIG. 3 is a diagram showing functional blocks inside the device A.
Reference numeral 18 is a binarization circuit for binarizing the data from the two-dimensional image sensor 13, 19 is an oscillation circuit, 20 is a pulse received from the oscillation circuit 19 to drive the two-dimensional image sensor 13, and a preset counter / gate. 21 is a drive circuit / address counter for controlling the display RAM 22 and the display RAM 22. Further, 23 is a shift register for controlling the display RAM 22, 24 is a liquid crystal drive circuit for driving the liquid crystal display 4, 25 is a switch which is switched by mode switching, and switches to the a side in the reading mode and to the b side in the recording / editing mode. . 26 is a CPU for controlling 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 above switch 25, and 31 is a DMA controller.

Next, the operation will be described. First, the power switch 1 is turned on and the reading mode is selected by the mode changeover switch 2.
As a result, the illumination light source 12 is turned on, the two-dimensional image sensor 13 performs reading, and the contents are 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 constantly driven by the oscillator 19 and the drive circuit / address counter 20.
The image signal from the two-dimensional image sensor 13 is applied to the preset counter / gate 21 through the binarizing circuit 18. The preset counter / gate 21 compresses the image signal according to the data given in advance by the CPU 26, and displays the obtained output via the shift register 23. RA
Send to M22. Then, the contents of the display RAM 22 are read by the display liquid crystal drive circuit 24 and displayed on the liquid crystal display 4.

The state of this read display is shown in FIG. As shown in FIG. 3A, the two-dimensional image sensor 13 reads a portion of the document B having a width x corresponding to the reading window 11, and this is displayed on the liquid crystal display 4 as shown in FIG. .

Next, the start / stop switch 3 is turned on to bring the device A into the readable state (start). Then, when the device A is moved in the direction of the arrow Y and it is detected that the read timing signal is received from the encoder 10, the data of one line of the image sensor 13 corresponding to the position of the marker 4a on the display 4 is set to the preset value. The image is recognized by the gate 27, and the image address counter 28 operates so that the image is stored in the image storage RAM 29. Then, the above operation is repeated thereafter according to the output of the encoder 10.
After a certain running, the start / stop switch 3 is turned off to bring the reading stop state (stop). Then, the same operation is repeated along another line of the document.

Next, the edit mode will be described.
As shown in the figure, it is assumed that one image (two Δ images) is read over three rows at different reading start points. In this case, the image is stored at the end of reading.
The image on the RAM 29 is as shown in FIG. 6 (a). Here, if one line is output, FIG. 7 (a)
An image as shown in is obtained. Next, regarding the second line, since the reading start position is different from that of the first line, if the output (recording) is performed as it is, an image becomes misaligned.
Therefore, the image on the image storage RAM 29 is shifted before output by using the editing function. In this example, the image can be shifted to the left.

The image shift will be described below. In the edit mode, a part of the image on the image storage RAM 29 is always transferred to the display RAM 22 by the DMA controller 31, and the liquid crystal display 4 displays the contents of the display RAM 22. Therefore,
When the edit key 5a in the key group 5 (specifically, the image shift key in this case) is pressed, the transfer control address of the DMA controller 31 is rewritten by the CPU 26, and the portion on the image storage RAM 29 different from that before the key is pressed. Shows R
It is transferred to AM22 and displayed. Therefore, if this operation is continued until the image reaches a desired position and then output is performed, an image without deviation can be obtained. This state is shown in FIG. 6 (b) and FIG. 7 (b). In FIG. 6 (b), 1
The image on the second line matches the image on the second line, and the image on the second line in this state is recorded as shown in FIG. 7 (b). The recording start position of the second row is the same as that of the first row. By repeating the above operation, the image in the image storage RAM 29 finally becomes coincident with the read image shown in FIG. 5 as shown in FIG. The image recorded over the period becomes an image without displacement as shown in FIG. 7 (c).

Next, the image recording operation will be described. When the recording mode is selected by the mode selector switch 2, the DMA controller 3 adjusts the head of the stored image to match the writing position.
The transfer control address of 1 is determined by the CPU 26. As a result, several lines before and after the writing position (for example, 1
~ 640 dot rows, 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 row of data is at the recording position, the start / stop switch 3 is turned on. Then, when the device A is moved and the write-out 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 sar head 16 and recorded. . At the same time, the transfer control address of the DMA controller 31 is rewritten, the display is scrolled, and the image to be recorded is shifted line by line in the direction opposite to the arrow Y direction. If it is not necessary to consider the positional relationship between the first scan and the second scan, the above scans are continued. If it is necessary to consider, turn off the start / stop switch 3 and confirm the contents of the image storage RAM 29 for the second scanning by the display 4, and as described in the above-mentioned edit mode. , The edit key is operated to align the head row of the second scanning data with the marker 4a, and then scanning is performed. The above situation is shown in FIGS. 8 (a) and 8 (b). Reference numeral c is a recording sheet. In addition,
Edit mode and record mode work interactively. A flowchart of the above operation of FIG. 9 is shown.

It should be noted that the display 4 displays the whole or part of the reading opening portion at the time of reading, or all the read images, and displays a part or all of the stored data at the time of recording or editing contents. It can be provided with a function of displaying or storing a recorded image including a recording portion during recording or a displayable recording portion on the display, but only two of them may be provided.

〔The invention's effect〕

As described above, according to the present invention, by checking the display unit, reading or recording can be performed very easily, and in particular, the read start point and the recording start point can be easily aligned. It becomes easier to read and record.
