DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of a facsimile apparatus according to the present invention will be described first with reference to FIG. A scanner head 2 is arranged below the table glass 1, and an image receiving mirror 4, a reflecting mirror 5, a condenser lens 6 and an image sensor such as a CCD 7 for receiving light passing through the image pickup mirror 4 are mounted on the scanner head 2. The scanner head 2 is moved at a constant speed by a motor 3 from left to right in the figure. A light source 18 is arranged above the table glass 1.
In the example shown in FIG. 1, a fluorescent lamp is used as the light source 18, and the fluorescent lamp is arranged facing the image receiving mirror 4 and above the image receiving mirror 4, and extends in the direction orthogonal to the moving direction of the scanner head 2.

A diagnostic film 19 as an image to be transmitted is placed on the upper surface of the table glass 1, and a milky white acrylic plate 20 is placed thereon. When a facsimile transmission operation is performed, the fluorescent lamp 18 is moved simultaneously with the movement of the scanner head 2 while maintaining the state of facing the image receiving mirror 4. Since the structure for this movement is not directly related to the gist of the present invention, its explanation is omitted. The fluorescent lamp 18 and the scanner head 2 are moved (scanned) from one end to the other end of the film 19, and the image on the entire surface of the film 19 is transferred to the CCD 7.
Is received by. Fluorescent lamp 1 with milky white acrylic plate 20
Light from 8 is evenly applied to the film 19.

When command information is input from an operation panel (not shown in FIG. 1), a control signal is generated from the main control circuit 15, and the control signal is input to the motor 3, the lighting substrate 16 and the timing circuit 17, As described above, the scanner head 2 is driven, the fluorescent lamp 18 and the like are turned on,
Scanning in the CCD 7 is controlled. The light from the fluorescent lamp 18 passes through the film 19, is reflected by the image receiving mirror 4 and the reflecting mirror 5, and is sequentially input to the CCD 7.

The signal output from the CCD 7 is input to the A / D converter 8, converted into a digital signal, corrected by the tone correction circuit 9 and temporarily stored in the buffer memory 10, and then, through the interface 11 and the modem 12. It is output to the communication line 13. A part of the output from the tone correction circuit 9 is stored and stored in a large capacity storage memory such as the hard disk 14. Main control circuit 15 described above
The control signal and the timing signal from the timing circuit 17 are supplied to the A / D converter 8, the tone correction circuit 9, the buffer memory 10, the interface 11, and the hard disk 14, and these are operated at appropriate timing.

In the tone correction circuit 9, the halftone portion of the image information is emphasized. As shown in FIG. 4, when the input Ei and the output Eo to the tone correction circuit 9 are shown on the horizontal axis and the vertical axis, the correction is performed so that a portion near the middle of the input Ei is greatly changed and output. To be done. As a result, when viewed on an X-ray, the changes in the black and white parts of the background, which hardly contribute to the diagnosis, are compressed, and the halftone parts that contribute the most to the diagnosis are greatly changed. This makes it easier to find lesions.

The image information input from the communication line 13 is stored in the hard disk 14 through the modem 12, the interface 11 and the buffer memory 10 so that the image can be read out and the image can be viewed at any time. In this case, the image information from the hard disk 14 can be viewed by copying it on a film, or can be viewed electronically by a cathode ray tube or the like.

In the above description, the case where the image of the film 19 is received by the CCD 7 only by the light from the fluorescent lamp 18 above the table glass 1 has been described, but the light source 21 is further attached to the scanner head 2 and the light from the light source 21 is attached. The film 1
It is also possible to reflect the light on the lower surface of 9 and read the film image with the combined light of this reflected light and the transmitted light from the fluorescent lamp 18. Further, as the light source 21 in this case, R (red), G
It is also possible to use three fluorescent lamps that generate respective lights of (green) and B (blue), and it is also possible to transmit a color image or store it in the hard disk 14. In addition, the light sources 18 and 21 described above are set to 50 Hz or 60
When the light is turned on by a commercial AC power supply such as Hz, moire occurs in the facsimile image, so it is preferable to turn on the light at a frequency of about 50,000 Hz.

FIG. 2 shows another embodiment of the facsimile apparatus according to the present invention. Since the structure below the table glass 1 is similar to that of FIG. 1, the corresponding parts are designated by the same reference numerals and their description is omitted. Omit it. In this example, a plurality of fluorescent lamps 18 are provided extending in the moving direction of the scanner head 2 to form a surface light source and cover the entire surface of the film 19. Therefore, in this case, it is not necessary to move the light source 18 when moving the scanner head 2. Also in this example, the transmission operation is the same as that shown in FIG.

FIG. 3 is a system diagram that can be used in the present invention. The various information input from the operation panel 31 is input to the main control circuit 15, and when the control signal output from this is input to the color image scanner 32, the CCD 7 is scanned and input to the color printer 33. When printing (for example, sublimation printing) is performed and input to the compression / decompression image processing circuit 34, transmission / reception signals are compressed / decompressed to efficiently perform transmission / reception, and when input to the hard disk 14, transmission / reception signals are transmitted. Are stored (stored for storage), and when input to the modem 12, image information is exchanged. Since these configurations and operations are well known, further description will be omitted.

[0015]

According to the facsimile apparatus of the present invention, since the light transmitted through the film 19 is used instead of the reflected light as in the conventional case, it is unclear and hardly usable. There is an effect that the facsimile transmission of the medical film image by the telephone line is possible.
