Description

DETAILED DESCRIPTION OF THE INVENTION The present invention creates a composite image by electrophotographic processing by combining information supplied from the outside in the form of an electrophotographic abdominal imaging device, a phototransmission device, or an electric signal with a previously prepared document. The present invention relates to an information recording device that facilitates image processing of desired portions when partially reducing or enlarging an image or editing an image in an information composite recording device or the like.

Taking an information composite recording device as an example, the content written on at least a portion of a document (hereinafter referred to as a document image) and the information supplied from the outside in the form of an electrical signal (hereinafter referred to as an external information signal image). A device that combines information and records on a single sheet of recording paper is called an information composite recording device, and has recently been used in the field of information recording.

An information composite recording device forms a document image and an external information signal image in the form of an electrostatic latent image on a photoreceptor, performs electrophotographic processing in the same manner as an electrophotographic copying device, and performs composite recording. FIG. 1 shows a schematic configuration of an example of an information composite recording device, in which an upper part of the main body 1 of the device includes a document table 2 that moves back and forth, and a document plate for holding down a document M placed on the document table 2. A presser plate 3 and an exposure lamp 4 for irradiating the original M are provided, and the reflected light from the original M is directed onto the photosensitive drum 8 by an optical system consisting of a first mirror 5, a lens 6, and a second mirror T. is guided to form an image on the circumferential surface of the photoreceptor 8a. A mechanical shutter 9 for blocking reflected light is provided in the optical path of the optical system, and an actuation means 10 including a solenoid is turned on and off by a position designation signal obtained in connection with a position designation slider SL13SL2 to be described later. Open or block the optical path. On the other hand, around the photosensitive drum 8, a charger 11, a developing device 12,
A transfer electrode 13, a separation electrode 14, a static elimination electrode 15, and a cleaning device 16 are arranged in this order, and on the upstream side of the developing device 12 when viewed from the direction of rotation of the photosensitive drum 8, external information supplied in the form of an electric signal is transmitted. A scanning and reproducing device IT is arranged to convert the optical image into an optical image and form the image on the photoreceptor 8a. For example, an optical fiber tube, a thin window recording tube, a laser beam scanning device, etc. are used as the scanning/reproducing device IT.
1.8 is a recording paper feeding plate; 19 is a conveyance device for conveying the recording paper P after transfer; 20 is a fixing device for fixing the composite image developed on the recording paper; 21 is a fixing device for fixing the developed composite image on the recording paper; This is the paper receiving tray.

Using such an information composite recording device, picture information that is supplied in the form of electrical signals before and after picture information A (hereinafter referred to as document image A) located at the center of a document M as shown in FIG. 2a, for example. To record a composite image as shown in FIG. 2b on recording paper P by arranging explanatory information B (hereinafter referred to as external information signal image B) and information C (hereinafter referred to as external information signal image C) of A. , as shown in FIG. 1, place the original M face down on the document table 2 of the recording device (that is, with the document image A in contact with the document table 2), and specify the position of the document to be composited. The sliders SLl and SL2 are set, and then the document holding plate 3 is placed over the document M. In this case, the original M is placed on the original platen 2.
Since the document must be placed face down, press the position designation slider SL while visually checking the position of the document to be combined.
It is difficult to set l and SL2, and the position of the slider set in such a state is inaccurate, and work efficiency is extremely poor. When a recording operation is started with the shutter 9 disposed in the optical path blocking the optical path, the document table 2 begins to move and the exposure process by the exposure lamp 4 begins, and the photosensitive drum 8 begins to rotate in the direction of the arrow to perform scanning. The reproducing device 17 first forms an electrostatic latent image of the external information signal image B on the photoreceptor 8a. At this time, the reflected light from the document M is blocked by the shutter 9 and therefore does not reach the photoreceptor 8a. When the document table 2 moves further and the slider SLl activates the position detection switch SW1 disposed over the moving path of the document table 2, the shutter actuating means 10 is energized and the shutter 9 is opened, and the scanning and reproducing device is activated. The operation of 17 is stopped. As a result, an electrostatic latent image of the original image A is formed on the photoreceptor 8a of the photosensitive drum 8, following the external information signal image B. Thereafter, when the document table 2 further moves and the slider SL2 set at the boundary position of the document image A to be recorded activates the position detection switch SW2, the shutter 9 blocks the optical path again and the scanning/reproducing device 17 is activated again. An electrostatic latent image of the external information signal image C is formed on the photoreceptor 8a following the original image A. The electrostatic latent images corresponding to the images B, A, and C thus formed on the photoreceptor 8a are developed by the developing device 12, and transferred onto the recording paper fed from the paper feed tray 18 by the transfer electrode 13, and then exposed to light. It is separated from the drum 8, fixed by the fixing device 20, and discharged onto the paper discharge tray 21. In the composite image shown in FIG. 2b, the original image A and the external information signals B and C span the entire width of the recording paper P, so switching between images B, A, and C is done using the original position designation sliders SL, SL2. position detection switches SWl, SW2
It is sufficient to operate the mechanical shutter 9 by opening and closing it, but if the composite image is a document M as shown in FIG.
Picture information in the center of. If the image is as shown in Figure 3b, which is a combination of A/ (hereinafter referred to as original image I) and explanatory information B and C as explained in connection with Figure 2, external information signal images B and C are recorded. Although it covers the entire width of the paper P, the original image N does not span the entire width of the recording paper P, so recording a composite image is more difficult than the composite image recording shown in FIG. 2b.

That is, at the time of recording, as shown in FIG.
Position designation sliders SLl, S at height positions Hl, H2
At the same time as setting L2, two white original shielding masks Sl and S2 must be inserted between the original platen 2 and the original w so that their side edges are aligned with the width positions Wl and W2 of the original image R. .

This is because if both sides of the original M and the original image N are not covered with white masks, the images of those parts will be recorded on the recording paper in the same way as the original image N, and a composite image as shown in FIG. 3b will be obtained. That's because there isn't. However, the work of setting the position designation sliders SLl, SL2 to the height positions Hl, H2 of the original image N and the work of aligning the side edges of the masks SL, S2 to the width positions Wl, W2 of the original image N are, as described above, As in the case of , this is a difficult task that must be done without being able to visually check the quality of the original because it is placed on the back side on the document table 2, and the work is time-consuming and inaccurate. . The present invention has been made in order to solve the problem of specifying the document position in conventional information recording devices. a mask member for shielding an original that can spread out to a desired width from each of the opposing side edges of the pair; and an original that can move over the side edges of the set of the document placement plate and extend between the side edges. After specifying an area of the document to be recorded using the mask member and the document position specifying member during recording, the document placement plate is reversed and the document on the placement plate is brought into close contact with the document table. It was configured as follows.

According to the present invention, a document is placed with the document image facing upward on a document placement plate that can be rotated and reversed with respect to a recording device, and a mask member that extends from a pair of opposite side edges of the document placement plate is placed. By widening the document to a desired width, the recording area of the document can be placed quickly and reliably while visually checking, making masking work much easier than in the past.

The present invention will be described in detail below with reference to FIGS. 5 to 7.

FIG. 5 shows an embodiment of the document placement plate of the information recording apparatus according to the present invention.

Upright pieces 2a, 2a are provided on both sides of one end of the document table 2, and a document placement plate 25 is rotatably supported by the upright pieces 2a, 2a with a pin 26.

The document placement plate 25 moves from a horizontal position that is almost the same as the document table 2 as shown in the figure to a position where it completely overlaps the document table 2.
It can rotate within a range of 80 degrees. Support legs 25a are attached to the lower surface of the document placement plate 25 for stably holding the document placement plate 25 in the horizontal position shown on the main body 1 of the apparatus. The document placement plate 25 is made of a material having appropriate weight and rigidity.
For example, it is made of a plastic plate, and has a raised part 25b at the center of its upper surface, and on the raised part 25b is shown an area that coincides with the original platen 2 when the original plate 25 is superimposed on the original platen 2. A boundary line 27 is drawn. Original plate 2
A guide bar 28 is provided on one side edge of the frame 5, and height position specifying sliders SLl and SL2 are attached to this guide bar 28.
It is designed to slide while being guided by. Slider S
Permanent magnets are built into the support heads 29 and 30 at one end of Ll and SL2, and the other end is adapted to be locked to the other side edge of the original plate 25. An embodiment of this height position designation slider SLl is shown in FIG. Slider SLl is made of springy material such as phosphor bronze and has a thickness of 0.1 mm.
Made of ~0.2mTfL material, width 5mu~10mm
It is a strip of A lock plate 32 that rotates with a pin 31 is attached to the opposite end of the slider SLl from the support head 29. Engage and slider S
Ll is fixed to the document placement plate 25. Slider S
It is convenient to attach scales to the upper surfaces of Ll and SL2 so that the positions of masks Sl and S2 can be visually checked. Mask Sl,S

Reel rods 33, 3 are installed near both side edges of the placing plate 25.
3. Wind it up and pull it out to the required length when necessary.
′ may be covered from both sides.

In the configuration shown in FIG. 7, it is preferable that the mask is automatically wound up on the reel rod 33 by the force of the spring when the mask is not used.In this case, when the mask is used, the mask is pulled out from the reel rod 33. Appropriate temporary fixing means, such as a magic fastener, must be provided on a portion of the mask and a portion of the document placement plate 25 to prevent the document from being wound up again on the reel rod. A reed switch 34 is provided beside the document table 2 directly below the path of the support heads 29, 30 of the sliders SL1, SL2, and when the heads pass directly above the reed switch 34, the reed switch 34 is closed by its magnetic force.

Now, using the information composite recording apparatus as an example again, the procedure for recording a composite image using the document placement plate according to the present invention will be explained with reference to FIG. A document M containing a document image N to be recorded is placed in a substantially horizontal state at a predetermined position on the raised portion 25b of the document placement plate 25.

If the recording operation is started here, the document table 2 begins to move and the recording operation is performed in the same steps as already described. In this embodiment, switching between the external information signal image B and the original image I is carried out by actuating the reed switch 34 disposed in the main body of the apparatus using a magnet built into the support head 29 of the slider SLl. Switching between N and external information signal image C is carried out by operating reed switch 34 using a magnet built into support head 30 of slider SL2, thereby operating shutter 10, respectively. The electrophotographic processing of recorded images is exactly the same as that already explained, so it will not be repeated here. Although the embodiment described above is an information composite recording device with a movable manuscript table, the present invention is of course applicable to an information composite recording device with a fixed manuscript tray in which the illumination optical system provided within the device main body is movable. The present invention can also be applied to information recording devices such as electrophotographic copying devices and photoelectric transmission devices that have reduction and enlargement functions.
