As one method of using the above-mentioned optical system, a method has been reported in which checkered stripes are printed on the surface of aluminum, light is irradiated onto the aluminum surface from the outside, and the amount of movement is detected using the light reflected from the checkered stripes.

By the way, in order to read a document that has been placed in close contact with the reader at an arbitrary position, a conventional method has been used in which a reading device is fixed and the document is moved at a constant speed. however,
With such a device, it is not only difficult to record thick documents such as books, but also requires a device that moves the document at a constant speed, which leads to an increase in the size of the entire device.
It is unsuitable as a portable image recording device and has the disadvantages of 2- high cost.

In this case, a method conceivable is to fix the document and move the reading device, contrary to the above method. In this case, a document feeding device is not required, but if the reading device moves at an arbitrary speed/direction, problems such as missing images or double recording may occur, and the speed of movement of the reading device may Regulation of the direction of movement is required, and as a result, the device becomes larger and more complex, making it unsuitable as a portable image recording device. .

In addition, the above-mentioned position detection method in the cursor-moving coordinate input device has the drawback that position information of the document image cannot be input at the same time as zero image recording, and it is difficult to position the image information. be.

[Purpose] The present invention has been made in view of the above-mentioned four points. By recording image information together with this position information, the image reading unit can be placed at any position and moved over the document at any speed/direction, making it possible to record images without recording omissions or double recording. The purpose of the present invention is to provide an image recording device of the type shown in FIG.

The position information detection member 9.10 will be explained below. Element 9, 10 tri, for example in the form of a thin cord, is wrapped around the rotary tube 13, 14 in the device 2. Each of these rotating cylinders is always trying to rotate in the direction of the arrow C1D as shown in FIG. 4 by each spring (not shown), and when the device is not in use, the stopper If
, 12 until the member 9., 12 comes into contact with the diagonal corner of the outer wall of the casing of the device 2 and stops F. IO is uniformly rolled.

When the operator pulls out or rewinds the member 9 or FiIO by holding the stopper 11 or Fi 12, the rotating cylinder 13
Also, HI4ti rotates in the opposite direction or the same direction as arrow C or D, and the amount of rotation is determined by the rotary encoder 11 or ri1
8. These rotary encoders 17.1
8 is a control unit 22 that sends a signal to increase or decrease the count by 1 in response to a change in the length of the 1/16 snowflake of the member 9°10.
After the power is turned on, the control unit 22 monitors the amount of rotation from the state shown in FIG. The coordinate position of equipment can be detected in units of 1/16th of a snowflake. FIG. 5 shows a block diagram of the reading and recording procedures and position information path of the control unit 22, and the configuration thereof will be described later.

The information control means will be explained using FIGS. 6 and 10. FIG. 6 is an explanatory diagram of divided blocks of the original 1, and FIGS. 7 and 10 are plan views showing respective positions of the apparatus 2 on the original.

First, the original l is divided into four blocks BL as shown in FIG.
Divide into I-BL4. Next, with each member 9, 10 fully wound as shown in FIG. 4, the operator turns on the power button 3 (FIG. 1). Power on indicator lamp 6
(Fig. 1) lights up, and from then on, the control section 22 (fourth,
5) serves as a cap that constantly detects changes in the length of the member 9#lO as described above. Operator presses stopper + 1, 12
are temporarily fixed at the diagonal corners of the document 1, and then the device 2 is placed in the position shown in FIG. 7, and when the address set button 4 (FIG. 1) is turned on, the control unit 22td
, turns on the address set display lamp 7, detects the length A of the position detection member 9, 100 shown in FIG. save. In the figure, q and pt indicate the respective lengths of the illustrated portions of the device 2.

Next, when the operator places the device 2 at position E in FIG. 8 and turns on the scan start button 5 (FIG. 1) in order to read block BL1 in FIG. 6, the control unit 22H
The display lamp 8 is turned on during one scan, and the device at that time is at position 20 f (X.

yo), member 9. RAM2 calculated from the length of lO
8. 3. Set this (X o e ”io ) as the reference point of document 1.

Fig. 10 shows the lengths m and n of members 9 and 100, and position information (
The relationship between X, y) is shown. x, ytf, m.

n and A in FIG. 7, it can be determined by the following formula.

Therefore, for example, in the case of FIG. 8, m=o, n2=2
+, , e2, x0=0, y0=0.

After that, after moving the device 2 in the sub-scanning direction to position F in FIG. , move it to the G position shown in FIG. 9, turn on the button 5 again, and scan to the H position. Below, B
After performing the same operation for L3 and BL4, the address set button 4 is turned off to complete the reading operation for the original l.

Next, the configuration of the control section 22 will be explained with reference to FIG. 5 mentioned above. The control section 22 is mainly composed of a well-known one-chip microcomputer 26 having built-in R, 0M27, and RAM28. A change of 1/1611 m in the length of the rotary encoder 17.18H1 member 9°10 in Figure 2 above is converted into a pulse 0PU26KJ[]t,OT)'
The lengths m and n of the J[K member 9.10 can be monitored.

When moving from the E position to the F position as in the case of FIG. 8, the CPU 26Fi can calculate the amount of change ΔX in X using the following calculation formula.

△X-7±, (k△Z-time i〒Sun Tzu Jk2m2+,, e2m2+ Z2)) In this\,
Δm and Δn are the amount of change in m and n ΔZ=1 [(m + Δm
]2-(n+Δn)2, (rll''-n2)) This device reduces the changes in m and n to 1/16Ill.
Since it can be detected in order, the amount of change in X △×Fi1/8I
It can be calculated on the order of IIl.

When the operator turns on the scan start button 5 at the E position,
CPU26Fi, 1 to monitor that △× becomes 1/8@厘, and when it moves to 1/8111, T for reading,
At the same time as the HD light source 19 is turned on, the counting circuit 30 starts operating. The counting circuit 30 counts the click pulses from the reference oscillator 29 from the point in time when the image is moved 1/8th of the way, and inputs a control signal to the image sensor 21 for the time required to read out one scanning line. One line of image data is serially output in synchronization with the output of the reference clock pulse only during the "H" period of this control signal. The detection current is amplifier 3
1, it becomes an image analog signal. This image analog signal is converted into a digital value of predetermined bits by an A/D converter circuit 32, further binarized by a predetermined image signal processing circuit 38, and then input to the image memory 28 as video data. On the other hand, 0PTJ26 is the control signal “H” from the control circuit 30.

By outputting the address of the memory where the aforementioned video data and address data on the document should be stored to the memory 23 in synchronization with the reference clock pulse during the interval, the video data and the address data of the document can be stored at a predetermined address. It will be done.

When the control signal from the counting signal circuit 30 falls to "L" level, the LBD light source 19 is turned off and the rotary encoder 1 is turned off.
7. Monitor input from 18 and again 1/8 iim
Wait for it to move.

As described above, while continuing to write the video data to the memory 23 and the address data on the document, the device 2 is moved in the sub-scanning direction until it reaches the edge of the document, and as shown in position F in FIG. Recording of block BL1 ends.

Next, a method of storing image information and position information in the memory 23 will be explained.

The 0P126 manages image information obtained by a series of readings from when the address set button 4 is turned on until it is turned off as one frame.

If the device 2 is located at address (XI #ys), the image data is located at address (x1=xo), (yl-
y, ) K corresponding city is stored. (×1.yl)#'i
Since it is given in units of 1/8-o, if the maximum frame size is A3, (4-Xo), (Vx-, Vo)
Both ri can be expressed with a maximum of 12 bits. Assuming that each memory 23 can store a maximum of 8 frames, the frame number Fi can be expressed in 3 bits, so the memory 23 can store [image data], [frame size], and [address (Xi
-XO)), C address (Vx-ye)), all image data can be completely described in units of one pixel.

Another method is to use only the first address as the address since N pixel data is obtained for one scanning fin, [frame i), (address (Xr - X(
+)), (Address (Vt - V6)).

[Image data], [Image data], . . . [Image data] (total N pieces of [Image data]) may be stored.

Furthermore, the address may be simplified depending on the reading accuracy, such as by using the address at the beginning of the block and omitting *, a, or frame blur.

Furthermore, since a normal document image has a lot of white image data, it is also possible to perform simple compression by storing only addresses on the document having black data in the memory 23.

The width of each block in the main scanning direction A is l'
J/g in. Therefore, block BL1
The position of the scanning start point E in the main scanning direction (Fig. 8),
If there is a difference of N/8 sm or more between the scanning start point position G of the next block BL2 and the main scanning direction position (Fig. 9), a recording gap may occur between block BLI and block BL2. , the scanning indicator lamp 8 blinks to warn the operator of this fact.

Further, as the device 2 moves in the sub-scanning direction, if the shake of the coordinate y in the main-scanning direction A is greater than a predetermined value, the second lamp 8 is blinked to indicate that there is camera shake, etc., and the operator You can also give a warning. □ [Other Examples] In the above embodiments, the coordinate position of the reading unit was calculated by detecting the change in length of the rope-like member as the position information detection member with the movement of the device using a rotary encoder. It is also possible to detect changes in length using a ribbon-shaped member with length information as a barcode and a league for reading it. .

In addition, in the above example, 12 members were provided on the diagonal line of the bottom of the device, but by adding one or two additional members, it is possible to detect the tilt of the device and move the original. 1° [Effect] As described above using the embodiments, according to the present invention, the coordinate position of the document can be set to the image reading device of the image recording device in a lengthwise manner. Since a positional information detecting means for detecting positional information (distance) is provided and image information is recorded in association with the positional information, mistakes such as recording omissions and double recording, which are conventional, can be prevented.
