43, a print controller 45, and an interface 46 are connected by a bus line 47.

FIG. 5 is a diagram showing a flow of processing performed by the CPU 21 to send the sheet 3 on the electronic whiteboard 1. CPU
The processing is started when 21 detects the rise of the operation signal of the sheet feed button 11.

First, in ST (step 1), the timer 24 is driven to start measuring time. Then, ST
At 2, the time measured by the timer 24 is the set time T1.
Judge inside. If it is determined that the time is not within the set time T1, the timer 24 is reset in ST3, and the sheet 3 is sent in ST4.

Then, in ST5, it is determined whether the falling of the operation signal has been detected. In this determination, the sheet 3 is sent until the falling of the signal is detected, and if it is determined that the falling of the signal is detected, the feeding of the sheet 3 is stopped in ST6 and the process is terminated.

If it is determined in ST2 that the time is within the set time T1, it is determined in ST7 whether the falling of the operation signal is detected. If the fall of the signal is not detected in this determination, the determination in ST2 is performed again. If the fall of the signal is detected, the timer 24 is reset in ST8. Then, in ST9, the timer 25 is driven to start measuring time.

Next, in ST10, it is determined whether the time measured by the timer 25 is within the set time T2. If it is determined that the time is not within the set time T2, the timer 25 is reset in ST11 and the process is terminated.

If it is determined in ST10 that the time measured by the timer 25 is within the set time T2, the process proceeds to ST12.
It is determined whether the rising edge of the signal has been detected. If it is determined that the rising of the signal is not detected, the determination in ST10 is performed again. If it is determined that the rising of the signal is detected, the timer 25 is reset in ST13. Then, in ST14, the timer 26 is driven to start measuring time.

Next, in ST15, it is determined whether the time measured by the timer 26 is within the set time T3. If it is determined that the time is not within the set time T3, the above-described ST
The processing of 4 to ST6, that is, the sheet 3 is sent from the time when the set time T3 has elapsed until the falling of the signal is detected, and when the falling of the signal is detected, the feeding of the sheet 3 is stopped and the processing is terminated.

If it is determined in ST15 that the time measured by the timer 26 is within the set time T3, the process proceeds to ST16.
It is determined whether the falling of the signal is detected. If the fall of the signal is not detected in this determination, the determination in ST15 is performed again, and if the fall of the signal is detected, in ST17,
The sheet feeder 28 is driven to feed one screen of the sheet 3. Then, in ST18, the timer 26 is reset, and the process ends.

As described above, the rise of the operation signal is detected, the fall of the operation signal is detected within the set time T1, the rise of the operation signal is detected within the set time T2, and the operation signal is detected again within the set time T3. , The sheet 3 is advanced by one screen.

Hereinafter, a case where one screen of the sheet 3 is transmitted by the electronic blackboard 1 and the printer 2 having the above-described configuration and control will be described. The power switch 5 is turned on in the electronic blackboard 1, and characters and figures are written on the sheet 3 of the electronic blackboard 1.

The operator presses the sheet feed button 11 on the operation panel 4 and sets the sheet feed button 1 within the set time T1.
Release the sheet feed button 11 again within the set time T2.
Is pressed and the sheet feed button 11 is released within the set time T3. With this operation, the sheet 3 is fed by the sheet feed unit 28 for one screen.

Further, the operator places the sheet surface to be printed in a writable state, and presses the "+" button 13a provided on the operation panel 4 of the electronic whiteboard 1 once to display "1" on the display unit 14. Then, copy button 12
When the sheet 3 is sent by one screen by inputting the data, the surface of the sheet 3 is read by the reading unit 30, and the read data is sent from the interface 32 to the printer 2.
The printer 2 receives the data from the interface 46, and controls the print unit 44 by the print control unit 45 to print one copy of the characters and figures written on the sheet 3.

As described above, the electronic blackboard 1 can feed one screen of the sheet 3 by performing a specific continuous operation in which the operator pushes and releases the sheet feed button 11 twice at a predetermined time interval.

When performing this specific continuous operation, if the operator does not release the sheet feed button 11 within the set time T1, the sheet feed button 1
The sheet 3 is fed until 1 is released.

Even if the operator releases the sheet feed button 11 within the set time T1, the sheet 3 will not be fed unless the sheet feed button is pressed again within the set time T2.

If the operator does not release the sheet feed button 11 within the set time T3 even if the operator presses the sheet feed button 11 at the set time T2, the time from when the set time T3 is exceeded until the sheet feed button 11 is released is released. Sheet 3 is sent.

According to the present embodiment, after the sheet feed button 11 is pressed, the sheet feed button 11
Is released, the sheet feed button 11 is pressed again within the set time T2, and the sheet feed button 11 is released within the set time T3, that is, the sheet feed button 11 is pressed twice at intervals of the predetermined set times T1 to T3. Only when a specific continuous operation of releasing is performed, one screen of the sheet 3 can be sent.

If it is determined in ST15 of FIG. 6 that the time is not within the set time T3, the process proceeds to ST4.
Steps ST6 to ST6, that is, the processing is terminated after the sheet 3 has been fed from when the set time T3 has been exceeded until the sheet feed button 11 is released, but instead of this processing,
If it is determined in ST15 that the current time is not within the set time T3, the electronic blackboard may end the processing.

According to the electronic blackboard performing such processing,
Even if the operator presses the sheet feed button 11 once and releases it within the set time T1, presses the sheet feed button 11 again within the set time T2 and keeps pressing it beyond the set time T3, even if the set time T3 is exceeded. Sheet feed button 11
The sheet 3 is not sent until the user releases the button.

Therefore, when it is desired to feed one screen of the sheet 3 by inputting the sheet feed button twice,
Even if the second input is erroneously pressed for a long time, an input error in which the sheet 3 is slightly fed can be prevented.

The set times T1 to T3 set in the ROM 22 of the above embodiment can be set in a rewritable memory such as a flash ROM (rewritable nonvolatile memory), and the set times T1 to T3 can be changed. An electronic blackboard provided with an input device may be used. Alternatively, this input device is provided outside the electronic blackboard 1 and the electronic blackboard 1 and the input device are connected to each other to set the time T.
An electronic blackboard having a configuration in which 1, T2, and T3 can be changed can also be used.

According to the electronic blackboard capable of changing the set times T1 to T3, the operator presses the sheet feed button 11 once and releases it within the set time T1, then presses the sheet feed button 11 again within the set time T2 to set the time. The time when the sheet feed button 11 is released before the time T3 is exceeded, that is, the time when the operator presses and releases the sheet feed button 11 twice can be freely set according to the operator's preference.

[0040]

As described above, according to the present invention, the sheet is fed one screen by operating the sheet feed button twice at a predetermined interval, and the time for operating the sheet feed button exceeds a predetermined time. By feeding the sheet only for the time exceeding the above, it is possible to provide an electronic blackboard that can improve the operability even when feeding the sheet for one screen or when feeding a small amount of sheet.
