FIG. 2 shows a partial schematic configuration of a microprinter which is an embodiment of an image processing apparatus according to the present invention. In this figure, F is a roll-shaped microfilm as an information recording medium, 1 is a projection lamp, 2.3 is a scanning mirror arranged at an angle of 90 degrees to each other, and 4 is a photosensitive film as an image recording medium. a drum; 5 is a shutter base disposed above the photosensitive drum 4 and has a slit (not shown) along its axis; 7 is a primary charger; 8 is a developer; 9 is a transfer charger; 10 is a fixing device, and 19 is a screen for enlarging and projecting the image on the microfilm F via a mirror 18. B
Reference numeral ``i'' denotes a power source that applies a developing potential to the developing unit 8, ``R'' indicates a relay that connects the current from the power source B, and 17 indicates an LED array in which n LEDs are arranged.

In the above configuration, the light emitted from the projection lamp 1 passes through the microfilm F. The light image of the microfilm that has passed is reflected by the scanning mirror systems 2 and 3 and passes through a slit (not shown) formed in the shutter base 5. The light that has passed through the slit scans and exposes the surface of the photosensitive drum 4, which has been uniformly charged by corona discharge by the primary charger 7, and the light-exposed area is neutralized to form an electrostatic latent image. The electrostatic latent image is developed by a developing device 8 supplied with a developing potential from a power source Bi. A transfer charger 9 applies an electric field to the developer toner on the photosensitive drum and transfers it to a transfer paper. The transferred image is fixed using a fixing device 10 by applying heat and pressure. Further, the image of the microfilm F passing by the light emitted from the projection lamp 1 is enlarged and projected onto the screen 19 via the mirror 18.

FIG. 3 shows the optical sensor S installed on the shutter base 5.
(s, -5n) shows how an image of microfilm F is scanned. Here, line segment a-a, line segment bb
, line segment c-c represents the optical sensor (S+
~5o) shows the arrangement direction.

The image on the microfilm F in FIG. 2 can be changed from the image on the line segment a-a as shown in FIG. 3 by moving the scanning mirrors 2 and 3 in the direction of the arrow in FIG. The image on b-b and the image on c-c are sequentially scanned and exposed onto the photosensitive drum 4, and the image is recorded on the transfer material P by a well-known electrophotographic process. At this time, a contact type image sensor (for example, a CCD (charge coupled device)) is placed on the path where the transfer material P reaches the photosensitive drum 4.
A printed area on the transfer material P is detected. This area detection and regulation of the area on the microfilm P is performed with the following configuration to obtain an appropriate image on the transfer material.

FIG. 4 shows a schematic configuration example of the main part of the means for regulating the area of the microfilm.

As shown in FIG. 4, the shutter base 5 mentioned above includes
A slit 6 is provided along the axial direction of the photosensitive drum 4, and a pair of shutter plates 11 and 12 are provided for controlling the exposure area of the photosensitive drum 4 in the axial direction by changing the opening length of the slit 6. ing. These shutter plates 1
1.12 is formed into an opaque film and is rewindably wound around the drive shaft 15.16 of the pulse motor 13.14. The opening width can be changed from both ends. Further, on the shutter base 5, optical sensors S1 to S using amorphous silicon or the like,
J are fixed at predetermined intervals.

In the configuration shown in FIG. 4, the optical image of the microfilm reflected by the mirror system 3 is projected onto the shutter base 5, which has a slit 6 and is provided with optical sensors 5l-5n. As shown in FIG. 2, the contact sensor C detects the area information of the printing section of the transfer paper P conveyed from the paper transfer port. Consider a case where the image area information of the microfilm and the area information of the printed section are combined. At this time, the pulse filters 13 and 14 move the shutter plates 11 and 12 via the drive shafts 15 and 16 to change the opening width of the slit 6.

In the above configuration, in the information recording device according to this embodiment,
Image information is recorded in the following manner. That is, prior to image exposure on the photosensitive drum 4, the scanning mirror 2.3 is pre-scanned, and the optical sensor 5I on the shutter base S is
The image of microfilm F is scanned and exposed to NSn. The image illuminance data detected by the optical sensors S1 to So during this pre-step is digitized by an A/D converter (not shown) and then incorporated into a CPU, which will be described later. The CPU binarizes this data using a predetermined threshold value (hereinafter referred to as slice level) and stores it in a RAM to be described later. Therefore, the illuminance distribution of the image is divided at predetermined time intervals in the scanning direction of the scanning mirror 2.3, and according to the arrangement intervals of the optical sensors S1 to Sn in the direction perpendicular to the scanning direction. Data brighter than the level is “O”
, dark data is sequentially stored in the RAM as "1". Here, when the microfilm F has a positive image, bright data is set to "1" and dark data is set to "0". As described above, the image area of the image on the microfilm F is automatically detected.

FIG. 5 is a block diagram showing the control system in this embodiment. In the figure, 20 is an image area detection means indicated by the optical sensors S1 to So, 21 is an image area setting means, and 2
2 is a mode switching means, and 23 is a CPU as a control means.
, 24 is an I (OM (read only memory)) that stores predetermined processing procedures of the CPt1 (central processing unit) 23, 25 is a RAM (random access memory), 26 is an aperture length of the slit 6, and a relay. image area regulating means for controlling the intermittent timing of R and the light emission of the LED array 17; and 27, a copy paper printing part detection means having a contact type sensor C for detecting the printed part of the transfer paper P in the middle of the paper feeding path of the transfer paper P. , 28 is an alarm signal generating means for generating an abnormal signal by the CPU 23 to notify the user when the microfilm image area and the printing area of the transfer paper overlap.The mode switching means 22 will be described later.

In the configuration of this embodiment as described above, the optical sensors S1 to
The image illuminance data detected by Sn is read into the CPU 23. The CPU 23 binarizes the read data and stores it in the RAM 25. Area information of the printing section detected by the transfer paper printing section detection means 2 (in this case,
The printing area information) is combined with the image area of the microfilm F, and if the image area does not match, the image of the microfilm is recorded. However, at this time, if a non-conformance occurs such that the printing category area and the image area overlap, the image regulating means 28 configured as shown in FIG. The alarm generating means 28 generates an alarm signal to notify the user.

The above is automatic image area detection. A printed image without solid black areas is obtained as shown in FIG. 8(B).

Incidentally, in this embodiment, it is also possible to manually specify an image area prior to starting the image recording operation.

That is, in the mode switching means 22 shown in FIG.
By switching the switch SW between terminals Pl+P2, I1
A switching signal is sent to the CPU 23 via the 0 port 31 to switch between automatic image area selection and manual recording area designation. This manual recording area specification is performed using the keypad 30 as shown in FIG. C.P.
It is stored as position information on the RAM 25 via U23. And to specify the image area manually,
For example, after pressing the keys "x" and "l" on the keypad 30 in sequence, the position of 'Xm l J is set in millimeters.

Next, press the keys “x” and “2” and then press “×lI+
2" position. On the other hand, to specify Y glaze, press the keys ry, and ``l'' and then set the position of ``Yml'' in millimeters. Next, after pressing the keys "Y" and "2", set the position of 'Ym2J (Fig. 1Theta (A)
and (B)). At this time, the origin of position setting may be, for example, the lower left corner of the screen. Therefore, when the switch SW is in contact with the terminal P, the image area regulating means 26 is controlled based on the position information of the manual recording area designation, and when the switch SW is in contact with the terminal P2, the automatic image area detection means is controlled. If the position information and the area of the transfer paper P detected by the transfer paper intermediate printing portion detection means 27 overlap, the image area regulation means 26 prevents the image from being recorded on the transfer paper, and also issues a warning signal to the user. . Further, when the image area on the microfilm and the area of the printing section on the transfer paper do not overlap, the image is recorded under the control of the image area regulating means 26.

That is, these control systems will be explained based on the flowchart shown in FIG. 8. First, in step 51, it is determined whether the switch SW is in contact with the terminal P1. If they are in contact with each other, in step S2, the image area (Xal, Xm2.Yal
, Ya2) is detected. Next, in step S3, it is determined whether printing is being performed using transfer paper P. If there is a printed area, it is determined in step S4 whether the printed area of the transfer paper and the image area of the microfilm overlap. If there is an overlap, control is performed by the image area regulating means 26 so as not to record the image on the transfer paper in step S5,
The user is also alerted by an alarm signal. If the images do not overlap in step S4, step S
6, the image area regulating means 26 records the area surrounded by (Xal, Xm2.Yal, Ya2) excluding the print area. If it is not printed on paper in step S3, the image area regulating means 26 records the area surrounded by (Xal, Xm2.Yal, Ya2) described above in step S7 (see FIG. 9(B)). .

On the other hand, in step S1 described above, the switch SW is connected to the terminal P,
If it is not in contact with the terminal P2, manual area designation (Xml) is performed in step S8 as shown in FIG.

Xm2, '/+al, Ym2), and then
In step S9, the image area regulating means 26 records the area surrounded by the above-mentioned (Xml, Xm2°Yml, Ym2).

Based on the position information, the CPU 23 determines the scanning direction of the microfilm, that is, the rotation direction of the photosensitive drum 4 by opening and closing the relay R shown in FIG.
The developing bias is controlled at 0N10FFL/by determining whether or not toner development is performed. In addition, in the direction perpendicular to the scanning direction of the microfilm, that is, the axial direction of the photosensitive drum 4, the pulse motors 13 and 14 shown in FIG. Control length. In this state, the scanning mirrors 2 and 3
At the same time as scanning, relay R is set to 0N10FFL, .
An image is recorded on the transfer material P.

FIG. 11 shows an LED array 17 in which LEDs I to LEDn are arranged in a straight line in the axial direction of the photosensitive drum 4 as the image area regulating means 26 when the microfilm is a positive image. According to this embodiment, the number of parts can be reduced,
The structure can be simplified. In this case, the LEDs in the area where the image is to be transferred do not emit light, and the LEDs in the area where the image is not to be transferred are made to emit light to control the recording area. The other configurations and operations are the same as those of the previous embodiment, so their explanation will be omitted.

Further, FIG. 12 and FIG. 13 show another embodiment of the present invention, and the same parts as in the above embodiment are given the same reference numerals. In this embodiment, an image of a microfilm is shown. is read by the CCD sensor 50, and the image is recorded on the optical disc recording cover 52 via the image processing device 51. 53 is a control circuit.

The other configurations and operations are the same as those of the previous embodiment, so their explanation will be omitted.

Furthermore, in the illustrated embodiment, a case has been described in which the image recording area in the circumferential direction of the photosensitive drum 4 is developed using a developing bias of 0N10FF, but the invention is not limited to this, and opening and closing of the entire slit by a shutter, primary charging, etc. 0N10FF or when the developing device approaches and separates from the photosensitive drum.

Furthermore, in the above embodiments, other recording media include transfer paper,
Although an optical disk has been described, a magneto-optical disk, a magnetic disk, a magnetic tape, etc. may also be used.

Further, in order to detect whether or not the fed paper is printed, other optical sensors may be used instead of the CCD. Furthermore,
When the image area of the microfilm and the printed area of the transfer paper overlap, the image is not displayed on the transfer paper and a warning signal is issued to the user, but the printed area of the transfer paper is detected by a contact sensor. However, when the printing section overlaps with the image area of the microfilm (automatic transfer 1 manual transfer), the paper feed drive means is reversed and stopped, and an alarm is activated (no. Furthermore, when multiple copies are instructed, only one blank sheet may be ejected, the copying operation may be stopped, and the user may be notified of the abnormality.

As mentioned above, when recording a film image on pre-printed format paper by automatically specifying the area and manually specifying the area, if the image area of the film overlaps with the printing category area of the transfer paper, the transfer There have been cases where the film image overlaps with the paper print area, resulting in an unusable copy, or conversely, the film image area is scratched by the transfer paper print area, resulting in an unusable copy, which the user does not notice. According to this embodiment, a warning is issued to the user, and blank paper is ejected so as not to produce unnecessary copy paper, so that the paper can be used again.

[Effects of the Invention] When the recorded area of the recording medium and the copying image area of the original document overlap, a warning is issued or the original image is not copied onto the recording medium, so it is possible to prevent erroneous copying.

In addition, time can be saved because the user is notified of the abnormality so that correction processing can be carried out quickly.
