Description

[Detailed Description of the Invention] Technical Field> The present invention is designed to easily create documents containing graphs and figures found in general office documents, technical documents, etc. The present invention relates to a simple input device that reads and inputs the information to a processing device.

<Prior Art> Conventionally, typical devices for inputting graphs and figures include those that optically read the figures and those that input coordinate positions in plane coordinates.

This optical input device uses an automatic reading scanner mechanism such as a TV camera or a copying machine, and these devices are costly and expensive.

There is also a simple scanner that scans manually, but
Although this is used in practical applications for reading simple numbers, etc., it is difficult to input figures and the like from a scanning point of view.

On the other hand, a tablet board (
(Those using electrostatic coupling, electromagnetic induction, and ultrasound)
There is.

Input using this tablet requires handwriting directly on the tablet to input the coordinates of each position sequentially, and it is not possible to input characters, figures, etc. written in advance on the paper. Inputting figures, etc. in particular took a lot of time and the input operations were troublesome.The present invention enables handwritten characters, figures, etc. written in advance on a sheet of paper to be inputted in a simple structure. The present invention provides an input device capable of inputting information, and in particular is an input device constructed by organically combining a simple optical reading means (scanner for manual scanning) and a tablet board.

<Embodiment> FIG. 1 is a perspective view showing the configuration of the input device of the present invention, in which 1 is a tablet board configured by an electrostatic coupling method or an electromagnetic coupling method, and 2 is a tablet board that is written on a manuscript sheet 4. letters,
To read figures, etc., it is C, which will be described later (see Figure 3).
In this way, the optical reading sensor 21 and the input pen 22 of the tablet board 1 are integrated.

3 is a processing device for processing input signals, and a signal line 5 with the reading head 2 and a signal line 6 from the tablet board 1 are connected.

7 is a manuscript sheet 4 placed on the tablet board 1;
This is a T-shaped guide plate that guides the reading head 2 in the horizontal direction when reading and scanning it with the reading head 2, and is movable in the vertical direction along one side of the tablet board 1.

A schematic configuration of the tablet board 1 is shown in FIG. 2, and in this embodiment, an electromagnetic coupling type tablet board is illustrated.

In FIG. 2, lla to lln are drive lines, 12a to 12
n is a sense line. Then, a desired position on the magnetically coupled tablet board 1 is indicated using an input pen 22 having an electromagnetic pen 22a made of an electromagnetic coil (or a pen made of a magnetic material). For example, the drive 111b and the sense line 12b are magnetically coupled by the electromagnetic pen 22a of the input pen 22. Therefore, it is possible to send an electrical signal to the position indicated by the input ben 22 from the sense line 12b. This signal is input to the processing device 3 via the signal line 6 in FIG.

Next, the specific configuration of the reading head 2 shown in FIG.
As shown in the figure, on the reading surface which is the lower surface of the head 2, an electromagnetic pen 22a of the input pen 22 and 8 dots are arranged in a row from the front in a direction perpendicular to the horizontal direction which is the scanning direction.
stomach. Optical reading sensors 21 that read images at a density of □ are arranged. This sensor 21 is, for example, a light source or a lens system.

Consists of a CCD sensor.

Further, the input pen 22 is detachably attached to the reading head 2 by an appropriate mechanism, and by removing it from the reading head 2, the input pen 22 can be used independently.

A drive signal is supplied to the input pen 22 from the processing device 3 via the signal line 5. This signal line 5 is shown for convenience, and the signal line for the drive signal and read information of the reading sensor 21 is also shown.

Therefore, in FIG. 1, the operator first places the original sheet 4 to be read on the tablet board 1, and slides the T-shaped guide plate 7 to position it at the reading position. Then, the reading head 2 is guided by the guide plate 7 from the left to the right from above the original sheet 4, and is manually horizontally scanned to perform reading.

At this time, each coordinate point is read out from the tablet board 1, and the read signal of the characters, figures, etc. of the manuscript/toro at each coordinate point is read by the read sensor 21, and the read information is sent to the processing device 3. will be processed.

FIG. 4 shows a block configuration of the processing device 3,
The coordinate signal output from the tablet board 1 is the signal line 6.
The data is temporarily stored in the buffer circuit 31 via the buffer circuit 31. Further, image information from the sensor 21 of the reading head 2 is transmitted to the signal line 5.
The signal is supplied to the image judgment circuit 35 via. This image information is information for a plurality of surrounding pixels with one coordinate point as a reference, and the image judgment circuit 35 slices it at a predetermined level and obtains a digital value t+I n
, tt□n, and temporarily stores this determination information in the buffer circuit 36.

The coordinate signal temporarily stored in the buffer circuit 31 is sent to the conversion circuit 32, converted into address information, and supplied to the address circuit 33 of the image memory 34.

The image memory 34 has a capacity to store the area of the tablet board 1 at a density of 8 pixels/1.11rrl, and writes data in the buffer circuit 36 to the image memory 34 based on address information supplied to the address circuit 33. It's crowded.

Therefore, image data is stored in the image memory 34 in an area within a predetermined range from the address position based on the coordinate points.

In this way, the image data obtained by reading the original sheet 6 is held in the image memory 34, and the image data is output to, for example, a CRT display device and displayed.

<Effects of the Invention> As described above, the input device of the present invention includes a tablet board on which a manuscript sheet on which characters and figures etc. are written and for detecting the coordinate position of the manuscript sheet, and a tablet board for detecting the coordinate position of the manuscript sheet. A manually scanned read head equipped with an optical read sensor for reading characters, figures, etc., and a tablet board equipped with said read head in juxtaposition with a sensor to give the coordinate position of said read head on the tablet board. an input pen, based on the scanning of the reading head, the input pen is used to read each coordinate point where the reading head is located from the tablet board, and at the same time, the character figure on the sheet at each coordinate point is read by the reading sensor. Since the device reads the information and inputs the read information to the processing device, it is possible to input characters, figures, etc. with a simple configuration, and this type of device can be provided with a simple input operation and an extremely low cost. In particular, by organically combining a simple optical reading means and a tablet board,
It is smaller and cheaper than conventional devices that use automatic scanner mechanisms such as TV cameras and copiers, and it is easier to input characters and graphics than conventional devices that use a simple tablet device. It has the feature of being able to be input.
