The paper conveyance section C includes a paper conveyance roller 18 and the paper 19, and the control means p includes a recording head drive section 16. It is composed of each of the following.

First, the recording head 14, which is the image forming means A, will be explained in detail with reference to FIG.

There are two types of recording heads: inkjet type and bubble jet type.

First, the inkjet method will be explained.

FIG. 2(a) shows an inkjet on-demand type. In the figure, 25 is a manual input from the recording head output control section 15, 26 is a piezoelectric element, 27 is a diaphragm, 2
8 is an erasable ink, 29 is a displacement amplification chamber, 30 is a metal diaphragm, and 31 is an ink nozzle.

Next, the principle of this inkjet method will be explained.

The piezoelectric element 26 deforms in accordance with changes in the human power signal 25,
The deformation motion is transmitted to the diaphragm 27, and the vibration is amplified in the displacement amplification chamber 29, compressing the metal diaphragm 30, which in turn presses the ink 28, causing ink to be ejected from the ink nozzle 31. Ru. FIG. 2(a) shows this state. The principle behind this is that if board 1 is placed at the tip of this jet, ink will be deposited on the north side of boat 1.

Next, the bubble jet method will be explained using FIG. 2.

FIGS. 2(b-1), (b-2), and (b-3) show the operation of this bubble jet method.

In the figure, 32 is a nozzle, 33 is ink, 34 is a bubble, 35
is a heating resistance element.

Next, the principle of this bubble jet method will be explained.

When a signal (pulse current) (not shown) is input, the heating resistor element 35 generates heat in response to the signal, and this heat generates bubbles 34 in the ink 33 (see Fig. 2 (b-).
1)). The pressure of the bubbles forces the ink 33 out of the nozzle 32 (FIG. 2 (b-2)'), and this force causes the ink 33 to fly out. When the human power of the traffic lights is stopped,
The air bubbles contract, the ink 33 that has flown out is cut off, and the next ink is replenished (FIG. 2 (b-3)'). This jetted ink 33 is deposited on the board 1 (not shown).

Since the ink 33 thus output by the recording head 14 is erasable as described above, the image formed on the board 1 can be erased.

Next, the configuration of the input operation section 20 shown in FIG. 1 will be explained using FIG. 3.

In FIG. 3, 36 is an LCD, 37 is a numerical keypad, 38 is an operation button for Read, 39 is an operation button for Copy, 40 is an operation button for Display,
41 is a start button for each mode.

Next, the operation of this embodiment will be explained using FIGS. 1 to 6 and according to the flowchart in FIG. 5.

In Figure 5, start at step 5a and turn on the power.
I (step 5b), when it is desired to read the image with the board 1 (FIG. 1) (step 5c), the central processing control section 11 activates the sensor drive section 9 and causes the scanner unit 7 to scan (step 5c). 5d), image sensor 6
By board! - Read the image (step 5e)
), the read image is stored in the image memory 22, which is the image storage means B (step 5f), and the next read image or previously stored image is stored on the board! If you want to display it on top (step 5g), press Display button 4.
0 (Fig. 3) to select the image you want to output from the image memory 22 (step 5h), start the screen drive unit 10 (step 5i), while the board 1 is scrolling, the recording head 14 Record the selected image on 1. In this case, the recording head! 4 consists of two recording heads 14A and 14B (Fig. 4).
For example, the recording head 14 is used for pixels 1 to 12 of the pixels 4a.
The recording head 14B records pixels A from 13 to 48 (step 5j).

Next time you want to print out the pixels (step 5h
), press the Copy button 39 (Fig. 3), specify the number of copies (step 52), and if you want to output the image stored in the image memory 22 (step 5m), specify the output image (step 5n). ), and if you want to output the image on board l, do not specify it (step 5m). If you do not specify this, the central processing control unit 11 recognizes that the image on board l is to be printed out, and prints out the image on board l. The unit 7 is driven to read the image on the board (step 5p), but at this time, the printer outputs the recording head 14A.
(the reason will be described later), the read image is subjected to thinning pixel density conversion in the pixel density conversion unit 21 as shown in FIG. 4(b), and is stored in the image memory 22 (step 5q). After that, since the output is from the image memory 22 in which the image is stored, the same operation as after step 50 is entered regardless of whether or not the image memory is specified.

This operation will be explained below.

First, the recording head 14 is driven to output onto the paper 19. For example, as shown in FIG. 6(a), the axial direction As shown in FIG. 6(b), the axial direction Slide the board! One possible method is to move the paper to paper 191:.

After moving and setting the recording head 14 to output onto the paper 19 using the method described above, the paper is conveyed by the paper conveyance section C, and the image is transferred from the image memory 22 onto the paper 19 by the recording head 14A. Output (steps 5r, 5s).

If a plurality of copies are specified, image output is repeatedly executed for the specified number of copies (step 5t) and the process ends.

In the above embodiment, the reason why the output is made only by the recording head 14A is based on the recognition that when copying as materials, one normal copy paper is equivalent to a normal report paper, but if the board 1 If you want to manually print the image recorded above at the same size, it is also possible to use the size of the paper 19 in the vertical direction of the board l and output it from both the recording head 14A and the recording head 14B. .

(Effects of the Invention) As described above, according to the present invention, there is provided an image forming means for forming an erasable image on a printout or the board, and an image storage means for storing an image read from the board. and a paper conveying section that conveys the paper to be printed out, and when the printout is performed, the image forming means is opposed to the paper conveyance section, and when outputting on the board, the image forming means is arranged to face the paper conveyance section, and when outputting on the board, the image forming means is arranged to face the paper conveyance section, and when outputting on the board, the image forming means is arranged to face the paper conveyance section. By equipping the control means for controlling the image forming means to face each other and form images, there is no need to transcribe the manuscript by hand on the board, allowing meetings to proceed quickly and saving time and effort. Efficiency can be improved, and the original that has been read and stored can be copied onto the board, and the image of the copied original can be erased or added to.
Minutes can be created efficiently, and furthermore, since the image forming means on the board replaces the image forming means on paper, a compact and economical board counting device can be obtained.
