A CCD control unit 84 for controlling photoelectric conversion of the CCD 25 by outputting a CCD control signal according to the shift signal and the clock signal.

Next, the image reading process in the image reading apparatus 1 will be described.

First, when the carrier member 3 is inserted into the carrier insertion port 11, the tip of the carrier member 3 passes through the interrupter, and the interrupter outputs a passage detection signal to the main CPU 71. The main CPU 71 outputs a drive signal and drives the second motor 41 to guide the carrier member 3 to a predetermined standby position in the main body case K. In this state, when a preview signal is output from the image display device via the interface unit 74, the main CPU 71 outputs a drive signal to the second motor driver 76 to drive the second motor 41,
Carrier member 3 until the passage detection signal of the tip is output
To move. At this time, the hole 54 is located directly below the xenon lamps 62-64. Next, main CPU7
1 is CC without turning on the xenon lamps 62 to 64.
By outputting a CCD control signal to the D control unit 84, C
The image control unit 83 is caused to read the image data from the CD 25. Next, the main CPU 71 causes the image control unit 83 to set the image data at this time to a luminance level of 0 gradation, thereby performing black level adjustment. in this case,
The brightness level of the image data is set to 256 gradations for each color, and 0 gradation corresponds to a black level and 256 gradation corresponds to a white level.

Next, in the main CPU 71, the light transmission parts 101, 101 of the carrier member 3 are xenon lamps 62-6.
The second motor 41 is driven by outputting a drive signal to the second motor driver 76 so as to be located immediately below 4. Next, the main CPU 71 turns on the xenon lamps 62 to 64, and also causes the image controller 83 to read the image data based on the light transmitted through the light transmission units 101, 101 to the CCD 25. In this case, the transparent original 4 has the protrusions 52, 52 ... And 53, 5
Since the position is regulated by 3, the main CPU 71
Can reliably read the image data of the unrecorded portion of the transparent original 4 via the light transmitting portions 101, 101. Next, the main CPU 71 executes the second operation according to the γ table stored in the built-in ROM so that the maximum value of the image data read at this time has a gradation of about 230 to 250.
The drive speed of the motor 41 is adjusted, and the xenon lamp 6
The white level is adjusted by adjusting the lighting times of 2 to 64, respectively. At the same time, the main CPU 71
Causes the image controller 83 to perform shading correction. That is, the image data of one row of the CCD 25 is evenly adjusted to 25 by the light amount of the xenon lamps 62 to 64, the reflection coefficient of the reflection plate 23, the aberration of the condenser lens 24, and the like.
The correction data is generated so as to have 6 gradations. By these processes, the dynamic range of the brightness level of the image data can be automatically maximized. In addition,
In the above-described series of operations, the hole 5 is detected by detecting the tip.
Although the black level adjustment, the white level adjustment and the shading correction are performed by 4, the hole portion 55 may perform these adjustments.

Next, the main CPU 71 outputs a drive signal so that the end of the leading (first) document window 51 is positioned at the beginning of the reading position.
After moving, the image reading is started. At the time of reading an image, the lamp control unit 8 is switched from the main CPU 71.
By outputting various parameters to 1, the lamp control unit 81 outputs a lighting control signal to the inverter circuit 61, whereby the xenon lamps 62 to 64 are turned on. The main CPU 71 causes the image control unit 83 to read the image data of the image while outputting the drive signal and the CCD control signal.

The read image data is stored in the image controller 8
After the shading correction, the color correction, and the enlargement / reduction processing are performed by 3, the data is temporarily stored in the buffer RAM 82. Then, the main CPU 71 has a buffer RAM 82.
The image data stored in is read and output to the interface unit 74. At the same time, the interface unit 74
Converts the image data into data of a predetermined communication format and outputs the converted data to the image display device.

After reading the image of the transparent original 4 corresponding to the first original window, the main CPU 71 continuously outputs the drive signal and rotates the second motor 41 a predetermined number of steps to make the second original. The carrier member 3 is moved so that the end of the window 51 is located at the beginning of the reading position. Then
The main CPU 71 causes the image control unit 83 to read the image data of the transparent original 4 by outputting various parameters to the lamp control unit 81 and the image control unit 83. The main CPU 71 repeats these processes, and sequentially supplies the third to sixth document windows 51, 5
The image data of the transparent manuscript 4 of 1 ... Is read and the image data is output to the interface section 74 each time. Note that in this preview processing, CC
At D25, the outputs of a plurality of adjacent CCD elements are combined into one pixel data, so that the reading is performed at a resolution of about 50 to 300 dpi, which is lower than the resolution at the time of reading the main image. Thereby, the reading time of the preview can be shortened. Further, since the image reading accuracy may be somewhat low, some play between the carrier base 12 and the carrier member 3 is allowed, and for example, the opening area of the carrier insertion port 11 may be widened, By loosening the engagement between the rack 46 and the sixth gear 45, the carrier member 3 can be easily inserted into the main body case K.

The image display device stores the input image data in the image data RAM (not shown), and when a predetermined key operation is performed, the image of the transparent document 4 in the designated document window 51 is displayed on the display device. To do.

On the other hand, when the user confirms the image on the display device and then designates the frame by the key operation,
A frame designation signal is output from the image display device to the main CPU 71 via the interface unit 74. Main CP
The U 71 drives the second motor 41 by a predetermined number of steps by outputting a drive signal to the second motor driver 76, so that the document window 51 of the designated frame is located at the beginning of the reading position. To guide you. Next, the main CPU 71 starts the main image reading, and the first
By outputting a drive signal to the motor driver 75, the first motor 32 is driven by a predetermined number of steps so that the carrier table 12 moves by one frame of the document window 51. At the same time, the main CPU 71 outputs a lighting control signal and a CCD control signal,
The above-mentioned shading correction and black-and-white color reference adjustment are executed and the image data is read. In this case, the carrier base 12 in one step rotation of the first motor 32
Since the moving distance of is extremely small, the image can be read with high accuracy. The read image data is output to the image display device by the main CPU 71 through the interface unit 74 in the same manner as described above. After that, in the image display device, an image display process based on the image data, an image processing / correction process such as brightness adjustment of the image data, an embedding process for fitting an image of an arbitrary frame into an image of another frame, and an MO (optical Magnetic disk) and D
Writing processing to a storage medium such as AT, MD, and floppy disk is performed.

As described above, according to the carrier member 3 of this embodiment, when the transparent original 4 is mounted, the white reference adjustment and the shading correction are performed on the image reading apparatus 1 by the unrecorded portion of the transparent original 4. The image data of the transparent original 4 can be continuously read. In this case, it is possible to perform shading correction and white reference adjustment with the brown base film of the same material as that of the transparent original 4, and as a result, the image reading device 1 can read image data with high accuracy. Further, the work of removing the brown base film from the carrier member 3 and mounting the transparent original 4 instead thereof is unnecessary, and if the carrier member 3 is inserted once into the image reading apparatus 1, shading correction and white reference adjustment are performed.
