Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a copy function for copying characters, figures, etc. written on a copy/reproduction board, particularly a conference board, and an electric device that displays patterns of characters, figures, etc. The present invention relates to a copy/playback board having a playback function for writing onto the board in response to a signal.

[Conventional technology]

2. Description of the Related Art Conventionally, copyboards having a copying function for copying characters, figures, etc. written on conference boards have been put into practical use. Conventional copyboards use a flexible film that is movable on the board as the writing surface, and converts the scanning light image obtained by shining light onto patterns such as letters and figures on the writing surface into electrical signals. The information is sent to a printer or other device and copied onto paper to create a hard copy of the information written on the writing surface.

[Problems to be solved by the invention] With the conventional copyboard as described above, it is difficult to manually write the contents of a prepared material manuscript or when it becomes necessary to rewrite the written contents that have been erased. I have no choice but to write it in. In addition, it is possible to reproduce the electrical signals obtained from the scanning light image of the copyboard between other conference rooms through communication lines on the copyboard, which has a larger screen size. It is often easier for everyone to view the information by playing it back, but even in this case, transcription to the copyboard must be done manually.

In this way, with conventional copyboards, even simple transcription requires manual writing each time, and especially when there is a large amount of written content, it takes a long time to write, which hinders the progress of the meeting. There is a problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide a copy/reproduction board which is equipped with a reproduction function to automate and speed up the conventional manual transcription process in order to solve the above-mentioned problems.

[Failure to solve the problem]

The copy/reproduction board of the present invention includes a writing surface on which a character or graphic pattern is written, and a copying means for creating a hard copy of the writing pattern on the writing surface in response to an optical image generated from the writing surface during copying. and writing means for writing the writing pattern on the writing surface in response to an electrical signal indicating the writing pattern applied from the outside during reproduction.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention.

The copy/playback board of this embodiment has a ben 9 mounted on a carriage 8 that can slide along a guide bar 7 in addition to a conventional copy board.
It has a configuration with an additional plotter attached. A flexible film 1 for writing has both ends attached to pulleys 3 and 4, and the portion in contact with the front surface of the board 2 serves as a writing surface.

When copying the written content, the pulley 3 is driven and rotated (the drive unit is not shown), and while the writing surface of the film 1 is wound in the direction shown by the broken line arrow A, the light source 4 provided on the back side of the board 2 is used to copy the written content. Light is applied to the surface of the film 1 wound around the pulley 3, and the scanning light image generated by the reflected light is sent to the image sensor 6.
Receive it at The image sensor 6 has a built-in line-shaped image sensor, receives the above-mentioned scanning light image, and performs photoelectric conversion with the image sensor to generate an electric signal corresponding to the light image pattern, which is then used as a read signal. Send. In conventional copyboards, this reading signal is sent to copying means such as a printer to create a hard copy on paper. Note that the light shielding plate 5 is provided to block direct light from the light source 4 from entering the image sensor 6 .

The reading means 9 that generates reading signals corresponding to the optical image pattern on the writing surface during copying is not limited to the configuration illustrated in FIG. Either configuration may be used. First, when the film 1 is run on the front surface of the board 2 to feed the screen, instead of being wound up by the pulleys 3 and 4, it may be wound endlessly between the two pulleys to feed the screen. In any of these cases, instead of the image sensor 6, a so-called contact type image sensor may be used, in which a line-shaped image sensor is provided close to the light reflecting location, and the light reflected from the writing surface may be Instead of generating an image, a transparent film 1 may be used to generate a transmitted light image at the writing surface. next)
Instead of scanning the written surface while moving the film 1 during copying, a contact image sensor may be run along the stationary writing surface to scan the writing surface.
Alternatively, a stationary writing surface may be imaged by an image sensor having a built-in planar image sensor disposed in front of the writing surface. In this type of scanning or imaging of a stationary writing surface, when the movable film 1 is not provided, the writing surface is fixed at a predetermined position, for example by using the front surface of the board 2 as the writing surface. It can also be applied in cases.

A guide bar 7 provided close to the writing surface is movable in parallel in the direction shown by arrow X, and a carriage 8 is provided so as to be slidable in the direction shown by arrow Y along this guide bar 7.
When the writing pen 9 is attached and is driven in response to a writing signal indicating a writing pattern (the drive unit is not shown), there is a process for moving the pen 9 to the writing position and writing. It consists of An inkjet printer head may be used instead of the pen 9.

When writing with a plotter that scans the surface of a writing tool such as a pen or a printer head, it is possible to write while the writing surface remains stationary, and therefore it is possible to write on a writing surface that is fixed at a predetermined position. Applicable. This professional also
It is also possible to write on the film 1, which has a film of heat-sensitive material formed on the surface, by using a line-shaped thermal printer head, for example, while horizontally moving and scanning as shown by the arrow X. . Furthermore, instead of moving the plotter or thermal printer head horizontally on the writing surface,
Alternatively, the guide bar 7 or the thermal printer head may be fixed at a predetermined writing position, and writing may be performed at the writing position while winding the film 1. In this case, an electrophotographic copying device or an electrostatic copying device is attached to the writing location of a plotter, etc., and a light beam writing signal or a voltage writing signal is used to internalize the copying device. It is also possible to write on the film 1 by inserting a charging pattern into the drum, developing it with toner, and then transferring and fixing it onto the film 1.

By adding any of the above-mentioned writing means to a conventional copyboard, it is possible to transcribe materials such as manuscripts and write contents once erased, as explained in Fig. 2. It becomes possible to automatically rewrite the contents of the conference room or transfer the contents written on the copyboard of another conference room.

FIG. 2 is a schematic diagram showing an example of application of the above-described embodiment. The copy/reproduction board 10 has the configuration shown in FIG.
It is connected to. The processor 12 is a microcomputer, and has a built-in memory for both reading and writing to store at least the reading signals from the writing surface of the copy/reproduction board 10 and the control circuit 11. Mode instruction circuit 13, transmission/reception circuit 14, image scanner 1
5, a storage device 16, and a printer 17 are connected.

The mode instruction circuit 13 is a switch for mode instruction.

In response to the instruction operation to the process 12, data indicating the item of the operation mode instruction is generated and sent to the process 12. processor 12
controls the operation mode in response to this instruction item data. For example, when a hard copy mode, that is, an operation mode for copying the written surface of the copy/reproduction board 10 onto a sheet of paper, is instructed, the processor 12 causes the control circuit 11 to send a drive control signal to the copy/reproduction board 10 to copy the writing surface of the copy/reproduction board 10. The surface is scanned 9, and the read signal received via the control circuit 11 is converted into a format signal for printing, which is sent to the printer 17 to create a hard copy on paper. In addition, in the soft copy mode, the writing surface is scanned and read signals are stored in the storage device 16.
For example, in the transmission mode, the read signal obtained by scanning and reading is sent to the transmitting/receiving circuit 14 and transmitted to other conference rooms via the communication line.

The operation mode exemplified above is based on the copy/reproduction board 100.
This can be achieved even if a conventional copyboard is used as a substitute.

The copy/reproduction board 1o of the present invention further has a reception/reproduction mode in which writing is performed on the writing surface using a reading signal sent from another conference room, a reproduction mode in which writing is performed from a soft copy, or a material manuscript on paper. It is possible to realize a mode in which writing is performed on the writing surface, such as a transcription mode in which writing is performed from the surface. For example, in receive playback mode,
The processor 12 converts the reading signal received from another conference room via the transmitting/receiving circuit 14 into a signal to send to the copy/playback board 1°, sends it to the copy/playback board 10 via the control circuit 11, and also sends the signal to the copy/playback board 10 via the control circuit 11. A drive control signal is sent from the circuit 11 to the copy/reproduction board 10 to cause writing to be performed by the aforementioned plotter or other writing means. In the playback mode, a desired recorded portion is read from the storage device [16] and sent to the copy/playback board 10 for writing. In addition, in the transcription mode, an electrical signal obtained by scanning the paper surface with the image scanner 15 is converted into a write signal and sent to the copy/reproduction board 10 to perform * writing.

By using the copy reproduction board 10 in this way, it is possible to write by hand, which is required with conventional copyboards.
It is possible to automatically transcribe contents written on copyboards in other conference rooms, rewrite 1-included contents that have been erased, or transcribe material manuscripts.

〔Effect of the invention〕

As explained above, the present invention has the effect that by adding a playback function for writing to a conventional copyboard, it is possible to realize a copy playback board that automates and speeds up transcription, which previously had to be done by hand. There is.
