[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(2) Internal structure of the device FIG. 1 schematically shows the internal structure of a microfilm image reading device according to an embodiment of the present invention.

As shown in the tree diagram, light from an exposure lamp 1h) serving as a light source is condensed by a condenser lens 2, directed upward by a mirror M1, and further condensed by a condenser lens 3. Microfilm F held by film carrier 4 by light passing through condenser lens 3
is irradiated from below. The image on microfilm F is
The image is magnified by the projection lens 5, changed direction by the fixed mirror M2 and movable mirror M31, and projected onto the screen 6. This forward path is called the projection optical path.

Next, the reading optical path will be explained. Here, the light receiving element 7 uses a contact type line sensor such as a CCD (charge coupled device) sensor. When image reading is instructed from an operation unit (not shown), the movable mirror M31 moves to the position M3.
After moving to the broken line position 2, it stops. Next, the image on the microfilm F can be read by the light receiving element 7 scanning the imaging plane 8 up to the position indicated by the broken line 78. Except when reading this image, the light receiving element 7 is located at the solid line position (
(initial position).

Next, reading image information on paper will be explained. The paper P placed on the paper feed tray 11 is moved by paper feed rollers 12, 1
3, the direction is changed by guides 14 and 15, and the paper is sent by a transport roller l6. Fluorescent light or LED
Light from a light source 20 such as a light emitting diode (light emitting diode) illuminates the paper original fAP that has been sent, and the reflected light passes through the loft lens array 21 and forms an image at the position of the light receiving element 7. The paper P fed at a constant speed is sent onto a paper ejection tray l8 by a paper ejection roller l7.

(2) Circuit Structure FIG. 2 shows an example of the circuit structure of the microfilm image reading apparatus according to the embodiment of the present invention, and arrows indicate the flow of image signals.

As shown in the tree diagram, the image on the microfilm or the image on the paper is charged and converted into an electric signal by the light receiving element 7.
The signal is input to the amplifier circuit 31 and amplified. The amplified signal passes through an A/D (analog-to-digital) conversion circuit 32 and a shading correction circuit 33, and is input to an image processing circuit 34. After image processing, the input signal of the image processing circuit 34 is outputted to an image forming device 37 such as an LBP through a printer interface circuit 35. In addition, Figure 2 shows
CPII (Central Processing Unit), operation section, etc. are omitted from illustration.

■Copying operation Therefore, in response to a copying instruction from an operation unit (not shown), image information read from the document on paper P is output to the image forming device 37 at times other than when reading a microfilm image, thereby converting the paper into paper. A microfilm image reading device with a copying function can be provided.

(2) Image Synthesis The apparatus of this embodiment can also synthesize microfilm image information and image information on paper by an image synthesis instruction from an operation section (not shown).

That is, as described above, image information from the paper surface is obtained through the light receiving element 7. As shown in Figure 2,
The image signal processed by the image processing circuit 34 is stored in the RAM (
The information is stored once in a memory 36, such as a random access memory. Next, when the microfilm image information is manually input to the light receiving element 7 and sent to the image processing circuit 34, the image processed image information and the image information stored in the memory 36 are synthesized in the synthesis circuit 38. It is sent to the printer interface circuit 35. As shown in FIG. 3, the microfilm image information 41 and the image information 42 on the paper are combined by the combining circuit 38 to form a combined image 43, and this combined image 43 is output from the image forming device 37.

At this time, as shown in FIG. 4, the image forming device 37
If the microfilm image information 51 and the image information 52 on the paper are combined to support double-sided recording, a composite image 53 for double-sided recording will be obtained. Here, the broken line indicates that the letter B is recorded on the back side.

■Various editing functions Furthermore, by adding editing functions to the image processing circuit 34, various editing processes can be performed. An image editing circuit 39 for this purpose is included in the image processing circuit 34. The image information from the page is processed by the image editing circuit 39 before being stored in the memory 36 after image processing according to instructions from an operation unit (not shown). Further, the image information on the microfilm is processed in an image editing circuit 39 before being combined in a combining circuit 38 after image processing. The image editing function here refers to masking and cropping after specifying the area. Enlarge/reduce horizontally and vertically,
Refers to partial movement, etc. Next, a practical example will be given.

As shown in FIG. 5, an area within a frame line 64 shown by a broken line is masked by manually inputting position data from an operation unit (not shown) on microfilm image information 61, and this image information and image information 62 on paper are masked. is synthesized, the code 63
This results in a composite image as shown in . That is, the masking area is replaced with image information on the paper.

Further, as shown in FIG. 6, when the image information 72 on the paper is reduced in size and moved to the right corner in response to an instruction from an operation unit (not shown), and combined with the microfilm image information 71, A composite image as shown by reference numeral 73 is obtained.

Note that if the printer interface circuit 35 is provided with an image transmission function, it becomes possible to electronically transmit image information after image composition.

[Effects of the Invention] As described above, according to the present invention, a document conveying means for conveying a paper original to a light receiving element for reading a microfilm image is provided, and the document image is transmitted through a light collecting means. Since the image is formed on the light-receiving element, it is possible to print the image information on the microfilm and copy the original using this device alone, without connecting a device such as an image scanner. In addition, by providing an internal image composition means, it is possible to easily compose microfilm images and original images, and by adding an image editing function, processing such as masking and partial enlargement of images can be performed during image composition. It can be carried out.
