Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multifunctional imaging device that combines a facsimile IJ device and a CRT device.

FIG. 1 shows an example of the configuration of a conventional image device having a facsimile device and a CRT device, where 1 is a facsimile device, 2 is a CRT device, 3 is a memory connected to the facsimile device 1 and CRT device 2, and 4 is a memory connected to the facsimile device 1 and CRT device 2. A communication line connection device 5 is a changeover switch that connects either the facsimile device 1 or the memory 3 to the communication line connection device 4.

When this device is used in local mode, the screen is input from the facsimile device 1 and stored in the memory 3. Next, the image is displayed on the CRT device 2 from the memory 3 for viewing. The use of such a local mode has been extremely limited, such as when testing the device itself when a trouble occurs in the communication mode described below.

Next, the operation in communication mode will be explained.

At the time of reception, facsimile image signals are input from the communication line connected to the communication line connection device 4, but the input image signals can also be directly input to the facsimile device 1 using the changeover switch 5, and are still stored in the memory 3. It is also possible to output the data to the facsimile device 1 or display it on the CRT device 2 after it has been temporarily stored. When displaying on the CRT device 2, the contents on the screen can be viewed and, if necessary, outputted to the facsimile IJ device 1 for recording, which helps save time and paper.

At the time of transmission, the data is sent from the facsimile IJ device 1 to the other party via the communication line connection device 4, or after being stored in the memory 3, it is sent to the other party via the communication line connection device 4. In the latter case, since the image information is stored in the memory 3, it can be sent to the other party as many times as desired, and the CRT device 2
You can check the sending screen by clicking .

However, when this imaging device is used to communicate with the other party over the phone, it is difficult to accurately convey the location to the other party even if the screen is sent, which reduces its effectiveness by half. Ta.

In order to solve these problems, the present invention uses a CRT device with one light pen and is provided with a memory for storing facsimile image signals and a memory for storing light pen drawing signals. The utility of the imaging device is increased by making it possible to superimpose and display various light pen drawing signals.

If the signal synthesis device 8 is realized by an OR circuit, the light pen drawing signal is superimposed on the facsimile input screen and displayed on the CRT device 2. If it is desired to erase the light pen drawing signal or the facsimile input screen during the process, the memory B or the memory can be erased by operating a button on the memory control device 9 or the like.

Since it has such a function, the device having the configuration of this embodiment can be used, for example, as a device for explaining to a large number of people, such as for education and advertising.

In this case, if a large screen display device is used that is connected in parallel with the CRT device 2 shown in the figure, its effectiveness will be even greater.

FIG. 3 is a block diagram showing the configuration of another embodiment of the present invention, in which 10 is a memory control signal generator that generates a signal for independently erasing memory A or memory B, 11 is a telephone, and 12 is a control signal. The device controls the connection of the 7 axis 1, the communication line connection device 4, the telephone 11, the memory A1 and the memory B.

In the figure, the symbols with a ``''' indicate corresponding parts of the counterpart device, and the functions are the same as those without the ``1''.

This device has the following main functions:

In parallel with this operation, the data is transmitted directly from the facsimile machine or from the memo IJA to the other party 1+111 through the control device 12, the communication line connection device 4, and the communication line.

At the other end, the data is stored in the memory A' through the communication circuit connection device 4' and the control device 12', and then displayed on the CRT device 2' via the signal synthesis device 8'. In this state, the sender and the other party 1
All will see the same screen on the CRT devices 2, 2'. Also, at this point, the control devices 12, 12' operate to bring the telephone IL 11' into the coupled state. CRT
Based on the screen on the devices 2 and 2', use the light pen 6 to mark the necessary points, such as points you want to explain, on the CRT device 2.
When pointing upward, this light pen drawing signal is stored in the memory B via the light pen control device 7, and is synthesized with the contents of the memory A and the contents of the memo IJ 13 through the signal synthesizer 8 and sent to the CRT device 2. to be displayed. If the signal synthesizer 8 is implemented as an OR circuit as in the case of the explanation of FIG. 2, the light pen drawing signal will be superimposed on the Fakunmi IJ input screen and displayed on the CR7' device 2. The light pen drawing signal is transferred from the control device 12 to the other party's control device 12' via the Fakunmi IJ image signal Yoshido-0 route and stored in the memo IJ B/, and at the same time is ORed with the contents of the memory A' through the signal synthesizer 8'. is taken and displayed on the CRT device 2'.

When attempting to erase the light pen drawing signal or the input screen, memory B or memo IJA is erased from memory B or memo IJA through the control device 12 by operating a button on the memory control signal generator 10, and at the same time, memory A is transferred to the other party.
' or sends a memory erase signal for memory B'. When the control device 12' of the other party receives this signal through the communication line connection device 4', it erases the memory A' or B' according to the signal. One of the features of the present invention is that the screen can be used while refreshing the screen any number of times.

As explained above, the present invention combines a CRT device with a light pen and a facsimile device, and has a memo IJ A for storing facsimile image signals and a memory B for storing light pen drawing signals.
