Abstract

PROBLEM TO BE SOLVED: To feed continuously and print continuously a plurality of screens in an electronic blackboard device. SOLUTION: Every time a setting key 2 for the number of sheets of a copy on an operation panel 17 is pushed down, a display of a 7 segment LED 23 is increased in increment, and successively changed from '1' to '9'. When the key 22 is further pushed down under a state of the display of '9', the display of the LED 23 becomes a special symbol display. By further pushing down the key 22, the display returns to '1'. When a copy key 21 is pushed down under a state wherein digits from '1' to '9' are set on the LED 23, printing for one screen of a content of the number of sheets according to the set digit is executed. Further, when the copy key 21 is pushed down under a state wherein the special symbol is displayed on the LED 23, continuous printing for a plurality of screens is executed.

The processing performed by the four-screen electronic blackboard of the present embodiment configured as described above will be described in detail below.

1. Forward Feed FIG. 4 is a flowchart when the forward feed key 20 on the operation panel 17 is pressed. When the forward feed key 20 of the operation panel 17 is pressed, the number of feed surfaces is set to 1 in S1, and the number of permitted feed keys is set to 1 in S2.
And the screen drive pulse motor 4 is set in S3.
Is rotated clockwise, and the screen 1 is moved from left to right (the direction of arrow A in FIG. 3) via the screen drive roller 2.

Then, after waiting until the screen home mark 5a of the screen 1 moves out of the detection range of the screen home position detection sensor 7 in S4, the screen home position detection sensor 7 detects the screen home position mark 5b in S5, and Wait until the screen home position is advanced by the number of pulses. Next, in S6, the number of feed faces is reduced by one, and it is determined in S7 whether the number of feed faces is zero. If the number of feed surfaces is 0 in S7, the screen drive pulse motor 4 is stopped in S8, and the normal rotation feed key operation ends. If the number of feed faces is not 0 in S7, the process returns to S4 to feed to the next screen face.

Before the screen 1 moves out of the screen home in S4, it is determined in S13 whether the normal rotation feed key 20 has been input. If the forward feed key 20 has been input, S14
It is determined whether or not the number of permitted feed keys is other than 0. If the number of permitted feed keys is not 0, the number of permitted feed keys is decreased by 1 in S15, the number of feed surfaces is increased by 1 in S16, and the process returns to S4. Check again whether the screen 1 has moved out of the screen home. If the normal feed key 20 is not input in S13, the number of permitted feed key times is 0 in S14.
Also returns to S4.

Similarly, it is determined whether or not the forward feed key 20 has been input before the screen 1 moves to the screen home position in S5. This is exactly the same as the above-described processing until the screen 1 moves out of the screen home in S4.

As described above, the forward feed key 20 input until the screen 1 moves out of the screen home in S4 and the screen 1 moves to the screen home position in S5. As a result, it is possible to directly feed the screen 1 to the next screen surface without stopping the screen 1 halfway, and the usability is greatly improved.

Since the number of times the feed key is permitted is set to 1 in step S2, even if the feed key is input a plurality of times, only the feed to the next next screen is performed directly. You can feed directly.

2. Reverse feed When the reverse feed key 19 on the operation panel 17 is pressed, the screen drive pulse motor 4 is rotated counterclockwise to move the screen 1 from right to left (in the direction of arrow B in FIG. 3) via the screen drive roller 2. Moving. Also, the reverse feed key 19 input until the screen 1 moves out of the screen home and before the screen 1 moves to the screen home position is processed. The other points are the same as those in the case of the normal feed.

3.1 Screen Copy When the copy key 21 of the operation panel 17 is pressed, the CPU
16 turns on the fluorescent lamp 8, rotates the screen driving pulse motor 4 clockwise, and moves the screen 1 from left to right via the screen driving roller 2 while moving the CC.
The data is read by D11, converted into a binary digital signal of 0/1, and simultaneously stored in the image memory 15 while being printed on the thermal printer 18.

When two or more copies are designated by the copy number setting key 22, the image data stored in the image memory 15 is copied to the thermal printer 18 for the second and subsequent copies.
To print.

The reading resolution is determined by the scaling circuit 1.
3 and the rotation speed of the screen drive pulse motor 4 can be changed.

FIG. 5 shows the display of the 7-segment LED 23 by pressing the copy number setting key 22 of the operation panel 17 a plurality of times.
FIG. 7 is a flowchart of four-screen continuous copying when the copy key 21 is pressed after setting as shown in FIG. Each time the copy number setting key 22 is pressed, 7 segments L
The ED23 display is changed as shown in FIG. here,"
The number of copies from 1 "to 9" indicates the number of copies, and in the case of FIG.

The display of the 7-segment LED 23 is shown in FIG.
When the copy key 21 is pressed in the case of FIG.
In step S17, the number of continuous copies is set to 4, the fluorescent lamp is turned on in step S18, the screen driving pulse motor 4 is rotated clockwise in step S19, and the screen 1 is moved from left to right via the screen driving roller 2 (arrow in FIG. 3). A
Direction). Thereafter, in S20, the 7-segment LED 23 is displayed as follows according to the number of continuous copies. This makes it possible to easily identify the number of pages currently being copied.

Display when the number of continuous copies = 4: FIG. 7 (a) Display when the number of continuous copies = 3: FIG. 7 (b) Display when the number of continuous copies = 2: FIG. 7 (c) Display when the number of times = 1: FIG. 7 (d) Wait until the screen 1 moves to the reading start position in S21, and if the number of continuous copies is other than 0 in S22, move the screen 1 to the reading end position in S24. Until it is read by the CCD 11 in S23,
It is converted into a 0/1 binary digital signal and printed on the thermal printer 18. Movement to the reading start position in S21,
The movement to the reading end position in S24 is managed by the number of pulses for driving the screen driving pulse motor 4.

That is, since the distance from the screen home position to the reading start position and the distance from the reading start position to the reading end position are constant, the screen driving pulse motor necessary to move the screen 1 by those distances is used. By managing the amount of rotation (that is, the number of drive pulses) of No. 4, the reading start position and the reading end position can be detected.

When the screen 1 moves to the reading end position in S24, it is determined in S25 whether or not the number of continuous copies is other than 0. If it is not 0, the number of continuous copies is reduced by 1 in S26, and the number of continuous copies is reduced in S27. It is determined whether it is 0, and if it is not 0, the process returns to S20 to copy the next screen. If the number of continuous copies is 0 in S27, the fluorescent lamp is turned off in S28 and S29
In step S30, the screen drive pulse motor 4 is stopped in step S30, and the 7-segment LED 2 is stopped in step S31.
The display of No. 3 is set to “1”, and the four-screen continuous copy operation ends.

Until the screen 1 moves to the reading start position in S21, it is determined in S35 whether the copy number setting key 22 has been input.
If the number-of-copies setting key 22 has been input, the number of continuous copies is set to 0 in S36, and 7 is set in S37.
"0" is displayed on the segment LED 23, and the process returns to S21. In this case, since the number of continuous copies is 0 in S22, the process branches to S28 to end the four-screen continuous copy operation. If the copy number setting key 22 has not been input in S35, the process returns to S21. Similarly, it is determined whether or not the copy number setting key 22 has been input before the screen 1 moves to the reading end position in S24. This is the screen 1 in S21 described above.
Is exactly the same as the process up to the time when is moved to the reading start position.

As described above, the screen 1 in S21
When the copy number setting key 22 is input until the screen moves to the reading start position and before the screen 1 moves to the reading end position in S25, the four-screen continuous copy operation can be interrupted.
