In the present embodiment, a case where the capacitive coupling method is used as the data input device 1 will be described as an example.

That is, in this capacitive coupling method, the electrode lines in the X direction and the Y direction provided on the coordinate position input surface portion 2 and the signal detection pen 4 contacting the coordinate position input surface portion 2 are statically coupled. It uses electrical coupling to measure the coordinates indicated at that time.

Next, a method of operating the data input device 1 configured as described above will be described with reference to FIG.

First, the original 5 to be used is placed on the coordinate position input surface 2 while the original guide plate 3 is housed in the main body of the data input device 1, and the original guide plate 3 is also placed.
The end face 3a of the L-shape is contacted, and one corner of the original 5 is aligned with the reference mark 0 provided on the upper surface of the main body of the data input device 1.

That is, in the present embodiment, the reference mark 0 at the upper side in the drawing is configured to be the coordinate axis reference position (0,0) of the coordinate position input surface portion 2.

Therefore, as shown in FIG. 2A, when the designated rectangular area P on the document 5 to be subjected to image processing exceeds the area of the coordinate position input surface section 2, the area of the coordinate position input surface section 2 is first set. The two points P ₁ and P ₂ of the four vertices of a certain rectangle are pointed by the signal detection pen 4.

Next, the remaining two points P ₃ and P _{4 that} are not on the coordinate position input surface section 2
The document guide plate 3 is moved while the document 5 is placed so that the position of is in the area of the coordinate position input surface portion 2 (see FIG. 2B).

This movement may be performed manually by the operator using the coordinate position input range mark Q provided on the main body of the apparatus 1 as a reference, or by a predetermined amount automatically by pressing an operation key (not shown). It may be moved.

Thus, the remaining vertices of the rectangular designated area P are
Point P ₃ and P ₄ with the signal detection pen 4.

By detecting the amount of movement of the document guiding guide plate 3 when pointing is performed later, it is possible to input coordinate position data outside the region of the coordinate position input surface portion 2 of the document initially set. .

Therefore, for example, by pushing the guide plate movement instruction button 12, the motor 11 is driven, and the pinion 13 and the rack 1 are driven.
By automatically moving the document guide plate 3 by 4, the coordinate position can be input.

That is, when the moving amount detection sensor S ₂ detects the detection piece R, the driving of the motor 11 is stopped and the guide plate 3 is stopped.
Is stopped.

By this movement, the document 5 having the X- and Y-axis coordinate positions to be pointed next is moved onto the coordinate position input surface portion 2 and the pointing becomes possible.

Here, since the moving amount of the document guiding guide plate 3 is determined by the mounting position of the above-described moving amount detecting sensor S ₂ ,
Coordinate shift data based on the amount of movement is stored in advance in the device, it is determined whether or not the guide plate movement instruction button 12 is pressed, and then based on the coordinate position data pointed and the coordinate conversion data.

Is detected by counting the number of slits 15a of the slit rail 15 S ₁ displacement detection sensor S ₃ mounted on the guide plate 3 with respect to the passes (4 (a),
(B)).

Therefore, the actual coordinate position data on the document 5 can be obtained by performing an arithmetic processing based on the movement amount data of the guide plate 3 and the coordinate position data pointed from the coordinate position input surface portion 2.

FIG. 5 is a block diagram showing an electrical configuration of the data input device 1 configured as described above.

A scanning signal of a predetermined level is sequentially applied to _m .

The control unit 23 is mainly composed of a timing generator 22, and a counter (X) and a counter (Y) which operate by the clock pulse output from the timing pulse generator 22.

On the other hand, the output pulse of the control unit 23 is counted by the counter (X) and the counter (Y), and the count signal is sequentially sent to the register 26.

Therefore, when the register 26 receives a detection signal at a predetermined timing sent from the peak detector 25, the register 26 indicates a specific coordinate position designated by the signal detecting pen 4 on the coordinate position input surface section 2. It is sent to the arithmetic processing circuit 27 as coordinate position data indicating that.

Therefore, when the movement instruction button 12 is pressed, the document guide plate 3 is automatically moved by the drive of the motor 11, and if the movement amount to be moved is predetermined, the movement amount is set. By storing the coordinate shift data based on the above in the arithmetic processing circuit 27, the shifted coordinate position data can be easily obtained.

That is, when the movement instruction button 12 is not pressed, the data output from the register 10 by the pointing of the signal detection pen 4 is used as it is as the X- and Y-axis coordinate position data for an image of a copying apparatus, a printing apparatus, or the like. Transfer to processor.

On the other hand, the coordinate position data when the signal detection pen 4 is pointed after the movement instruction button 12 is pressed is output by the guide plate movement amount detection circuit 28 to the arithmetic processing circuit 27. The data is sent to an image processing device such as a copying device or a printing device as coordinate-converted data based on preset coordinate shift data.

If the guide plate movement amount detecting device has a structure in which the movement amount of the document guiding guide plate 3 can be freely set as shown in FIG. 4, the guide plate movement amount detecting circuit 28 can move the movement amount detecting sensor S The movement amount is detected by counting the detection signals detected in ₃ , and the arithmetic processing circuit 27 performs arithmetic processing based on the movement amount and the coordinate position data output from the register 26 to convert the coordinate position. Data is obtained and the coordinate position data is sent to an image processing device such as a copying device or a printing device.
