Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to information recording devices such as microfilm reader printers, copying machines, and image display devices.

More specifically, when recording the main image information to be recorded,
A postscript function that allows image information to be combined and recorded in a form in which desired/optional postscript image information, such as date, characters, symbols, etc., is added to the main image information, if necessary. The present invention relates to an information recording device comprising:

(Prior Art) Information recording apparatuses themselves having the above-described write-once function are already known.

For example, image information (main image information) of a manuscript, microfilm, etc. is exposed onto an electrophotographic photoreceptor as a recording medium to form an electrostatic latent image corresponding to the image information, and this latent image is developed. Develop the toner using a means, and transfer the developed image to recording paper (transfer material).
Separately from the above-mentioned main image information exposure means, desired additional image information such as the date is input onto the photoreceptor by external input. The additional image information exposing means is used to expose additional image information such as the date on the portion of the photoreceptor surface that corresponds to the screen area specified by the area specifying means within the screen of the main image information. By doing so, an electrostatic latent image corresponding to the main image information and an electrostatic latent image corresponding to the additional image information are formed on the photoreceptor in a combined form.

The process of developing, transferring, and fixing the composite electrostatic latent image is then executed to obtain a composite recording material in which desired additional image information is added (additionally recorded) to the main image information on the same recording paper. be.

As the exposure means for the additional image information, for example, a light emitting element array assembly is used, and this is arranged so as to face the surface of the photoreceptor in parallel to the direction (main scanning direction) orthogonal to the surface movement direction (sub-scanning direction) of the photoreceptor. By controlling each light-emitting element of the light-emitting element array assembly in response to a time-series electric digital pixel signal corresponding to the desired additional image information input manually using the input means, the electronic bulletin board can be displayed. In this method, desired additional image information is selectively exposed (written) in main scanning and sub-scanning on a pre-specified area surface portion of the photoreceptor surface to form an electrostatic latent image corresponding to the information.

FIG. 11 shows that when outputting negative image information 100 of a negative image type microfilm F as shown in FIG. A screen example of a recorded material P that has been subjected to additional writing processing and outputted to an arbitrary screen area portion 103 designated in advance by the designating means is shown.

(Problem to be Solved by the Invention) In an information recording device equipped with the above-mentioned write-once function, when the write-once processing is performed, the recorded portion of the main image information and the recorded portion of the additional image information overlap each other (image duplication). ), the recorded content of the main image information, additional image information, or both of the overlapping parts will be mixed up and cannot be determined, and the recording will have to be re-recorded as a recording failure. Therefore, the recording position of the additional image information specified in advance must be carefully determined and specified accurately so that it does not overlap with the main image information, or even if there is overlap, the mutual information content can be determined. It took a lot of effort to add additional measures.

In view of the above, it is an object of the present invention to facilitate and speed up the additional write operation.

(Means for Solving the Problems) The gist of the present invention is an information recording device equipped with a write-once function and characterized by the following configurations (1) and (2).

(1) Main information recording means for recording main image information to be recorded on a recording medium, and screen area designating means for specifying an arbitrary screen area part within the screen of the main image information as an additional information recording part. and add desired additional image information such as date and characters as image information different from the main image information to the recording medium corresponding to the specified screen area section of the main image information by the screen area specifying means. Additional information recording means for additionally recording in a screen area, and additional image information for specifying main image information by the screen area specifying means within the screen area without causing any overlap with the main image information in the area. A writable space section search means for searching for the existence of an additional writeable space section that enables recording processing in the form of additional writing; 1. An image recording apparatus comprising: control means for controlling the additional information recording means to record additional image information in a surface area on a recording medium.

(2) If the above-mentioned writable space section search means does not search for the existence of a writable space section, based on the signal, a warning means that displays this fact is activated or the recording operation of the device is stopped. An information recording device characterized in that it is configured to perform both of the following:

(Function) That is, according to the information recording device having the configuration described in (1) above, the screen area specifying means roughly defines an arbitrary surface area on the screen of the main image information in which the additional image information is to be added. After that, the appendable space part search means will automatically search for a space part in the above specified screen area where additional image information can be added without overlapping with the main image information part, and then An append mode in which the recording of additional image information is automatically controlled for the surface area portion of the recording medium corresponding to the automatically searched space portion, and there is no overlap between the main image information portion and the additional image information portion. Image information recording is executed.

Therefore, the operator's operations during append processing are limited to manual operation of the desired appended image information and rough designation of the append location within the main image information screen, and there is no need to carefully identify and specify the append location. becomes easier and faster. Moreover, the economical efficiency is improved since recording failures and recording redos due to duplication of the main image information part and the additional image information part do not occur.

Furthermore, when the search means finds that there is no additionally writable space within the specified additional write location, the system activates a warning means to display this as in configuration (2) or stops the recording operation of the device. Recording failures can be prevented by canceling the recording or by performing both. In this case, an operation is performed to change the designation of the additional recording location, and image information recording in the additional recording mode is executed again.

(Example) Hereinafter, an example of a microfilm reader printer as an example of an information recording device equipped with a write-once function according to the present invention will be specifically described.

(A) Overall schematic structure of the reader printer (FIGS. 1 to 3) FIG. 1 is a perspective view showing the schematic structure of the reader printer of this embodiment.

0, and its information content can be read (reader mode).

A leader section is constituted by a member extending from the projection lens 5 to the projection screen 10 described above. A indicates the optical path of the reader section.

Reference numerals 11 and 12 denote first and second L left-handlers arranged at 90 degrees to each other and mounted and supported on a common movable carrier 50, and these first and second scanning mirrors 11 and 12

The reciprocating movement is controlled R/W in the lateral direction by a drive means (not shown).

13 is a horizontally long slit plate disposed below the second scanning mirror 12, 13a is a slit of the slit plate, and 15 is a photosensitive drum as a recording medium of the printer mechanism disposed below the slit plate 13. As shown in FIG. 3, the printer mechanism in this example is a transfer type electrophotographic copying mechanism using an electrophotographic photosensitive drum 15 which is rotationally driven as a recording medium. This will be discussed later.

The movable carrier 50 supporting the first and second scanning mirrors 11 and 12 is always (reader mode) in such a way that the first scanning mirror 11 is withdrawn to the side from the optical path A of the reader section as shown by the solid line in FIG. It is waiting with the non-intervention evacuated state position as the home position.

When the copy start key (not shown) is pressed while the image information of the target image frame of the microfilm F is being projected as an enlarged image onto the projection screen 10 in the reader mode, the movable carrier 50 or the evacuation shown in FIG. The first scanning mirror 11 is moved forward from the home position in the direction of the optical path A of the reader section and enters into the optical path A of the reader section, and as shown by the solid line in FIG. When a predetermined state has been reached in A, that position is set as the scanning start position and further forward movement R is stopped.

A forward movement process R of the movable carrier 50, that is, the first and second scanning mirrors 11 and 12, from the retreat home position shown by the solid line in FIG. 2 to the scanning start position shown by the solid line in FIG.
is hereinafter referred to as ``pre-scan''.

Next, at a predetermined control timing, the movable carrier 50, which is at the scanning start position shown in FIG. 3, is moved backward W in the opposite direction to the forward movement R, and returns again to the retracted position shown in FIG. This backward movement process W will be referred to as "one scan" hereinafter.

In this main scanning process W, the image information light of the target image frame on the reader optical path A that is sequentially scanned by the first scanning mirror 11 passes from the second scanning mirror 12 to the rotating photosensitive drum 15 via the slit 13a of the slit plate 13. The light is incident on the drum surface and is imaged on the drum surface.

That is, slit scanning exposure of the main image information to the surface of the drum 15 is executed.

B is the first scan in the pre-scan process R and main scan process W.
From the scanning mirror 11 to a photoelectric conversion element array S l to be described later
""' indicates the optical path of the blinking portion reaching S n and the surface of the photosensitive drum 15.

The printer mechanism section is constructed by disposing image forming process equipment around the photosensitive drum 15, as shown in FIG. That is, the photosensitive tram 15 is rotated around a support shaft 15a in a clockwise direction indicated by an arrow E at a predetermined circumferential speed, and its outer surface is uniformly charged by a charger 16, and the charged surface is By receiving the image exposure by the main scan W, electrostatic latent images of image information corresponding to the target image frames of the microfilm F are sequentially formed.

Next, the formed latent image is developed as a toner image by the developing device 17, and the toner image is transferred onto a transfer material P that is synchronously fed between the photosensitive drum 15 and the transfer charger 18 from a paper feeding section (not shown). The images are transferred sequentially.

The transfer material P to which the toner image has been transferred is separated from the surface of the photosensitive tram 15, is conveyed to a fixing device (not shown), undergoes image fixation, and is output as a recorded matter (copy). After the image has been transferred, the surface of the photosensitive drum 15 is removed by a cleaning device 19 to remove residual toner and other adhering contaminants, and then exposed to light from the front by an eraser lamp 20 to be neutralized and cleaned both physically and electrically. image and is repeatedly subjected to image formation.

(B) Addition function ■Screen area designation means (Figs. 1, 4, and 5) In Figs.・
37b) and a pair (37c and 37d) parallel to each other in the vertical direction.

The pair of parallel cursor wires 37a and 37b in the left and right direction can be manually moved in parallel in the up and down directions T and υ, respectively. However, both 37a and 37b cannot move by climbing over each other. Each of the pair of vertically parallel wire rods 37c and 37d can be manually moved in parallel in the horizontal direction H-I. However, both 37c and 37d cannot move by climbing over each other.

The shadows of the cursor wires 37a-37b, 37c, and 37d are reflected on the back surface of the screen when image information is projected onto the projection screen 10, and are visually recognized together with the projected image information from the front side of the screen.

In the reader mode state in which image information is projected onto the projection screen 10, the four manual cursor wires 37
Move the a-37b, 37c, and 37d vertically and horizontally, respectively, to move the cursor to any area on the image information screen projected on the screen 10 where you want to add desired additional image information such as the date. Wire rods 37a and 37b.

It is surrounded by projection lines 37c and 37d.

Each of the cursor wires 37a and 37b was moved.

The movement stop positions of 37c and 37d are determined by position detection sensors (38a and 38b in the control system block diagram in Fig. 5), respectively.
38c and 38d), and these signals are input to the main control circuit (CPU) 39.

As a result, in the main image information screen projected on the screen 10, the surface area surrounded by the four cursor wire 12 engraving lines, that is, the four intersection points h-l-j-k of each cursor wire projection line ( The main control circuit 3 determines the coordinates of the rectangular area whose vertices are (Fig.
It is calculated in step 9 and becomes the specified state.

■Additional information recording means (Figures 3.5 to 8) In FIG. This is an information exposure device.

The additional information exposure device 21 of this embodiment is constructed using a light emitting element array 22 such as an LED and an exposure lens 23. FIG. 6 is a plan view showing the arrangement of the device 21 with respect to the photosensitive tram 15, and FIG. 7 is an enlarged cross-sectional view of the device 21.

The device 21 is located on the left and right chassis side plates 60 and 6 of the printer mechanism.
0 (FIG. 6), the guide shaft 25 is mounted and supported parallel to the generatrix direction of the photosensitive drum 15 between the slide bearings 26 and 26.
A roller wheel 28 (FIG. 7) is provided on the bottom side of the exterior casing 27 of the device 21, and the roller wheel 28 (FIG. 7) is mounted on the immovable horizontal board 61 disposed between the left and right chassis side plates 60. By doing so, the photosensitive drum 15 is moved along the guide shaft 25.
It is free to slide smoothly in the left and right direction J-K parallel to the generatrix. The above-described sliding movement in the left and right directions is driven by a drive mechanism (not shown in the figure), which includes, for example, a forward/reverse drive pulse motor and a timing belt.

Therefore, the cursor wire 37a of the screen area specifying means described above.
Main control circuit 3 is activated by moving 37b, 37c and 37d.
9 (FIG. 5), so that the device 21 is located at a required position in the photosensitive drum generatrix direction corresponding to the coordinate position of the surface area to which additional image information is to be added within the screen of the main image information. The main control circuit 39 controls the motor controller 40 (FIG. 5) of the moving drive mechanism of the device 21, so that the drive motor M is driven forward or reverse by a predetermined rotation angle. As a result, the device 21 is driven to slide in the left-right direction, and the device 21 moves to the above-mentioned required position and stands by at that position.

As shown in FIG. 8, the light emitting element array 22 in the device 21 has a plurality of light emitting elements such as LEDs arranged in one row (
or multiple columns).

Desired additional image information such as dates and characters is manually input to the main control circuit 39 using appropriate manual means 41 (FIG. 5) such as a keyboard, and is converted into a time-series electric digital pixel signal.

Then, rotational driving of the photosensitive drum 15 of the printer mechanism is started for copying, and the first and second scanning mirrors 11
・After the main scan of the main image information (FIG. 3) is started in step 12, the main control circuit 39 performs a predetermined write operation that is calculated in accordance with the additional image information addition coordinate position specified by the main control circuit 39. From the start timing, the driver 42 of the light emitting element array 22 (FIG. 5) responds to the time-series electrical digital pixel signal corresponding to the manually added additional image information.
is controlled so that the individual light emitting elements fl, - mutually.

...Jln is selectively controlled to flicker (main scan control), so that the light from the light-emitting element illuminates the surface of the photosensitive drum 15 in an electronic bulletin board manner through the imaging lens 23 in the optical path G (FIG. 7). An electrostatic latent image corresponding to the input additional image information is formed. The writing position of this additional image information on the surface of the photosensitive drum 15 is such that the main image information exposed by the main scan with the first and second scanning mirrors is written on the surface of the photosensitive drum 15 after the specified processing is performed within that screen. This is within a surface area on the photosensitive drum 15 corresponding to the screen area to be displayed.

■Additionally writable space search means (Figures 1, 5, 9, and 10) As mentioned above, this is the image area specifying means 37.
A-37b, 37c and 37d (Fig. 14) Recording processing in which additional image information is added within the specified screen area of the main image information without causing any overlap with the main image information within the area. This is a search to find out whether there is a space for additional writing that allows for writing.

In FIG. 1, S, -Sn are photoelectric conversion element arrays (photosensor arrays made of amorphous silicon, etc.) arranged at predetermined intervals near the slit hole 13a along the length of the upper surface of the slit plate 13.

This search by the writable space search means is performed by specifying the writable area using the image area specifying means 37a, 37b, 37c, and 37d, and by inputting the required writable image information using the input means 41 (FIG. 5). By pressing the illustrated copy start key, the first and second scanning mirrors 11 and 1 are
2 moves to the pre-scan movement R and reaches the scan start position (FIG. 2→FIG. 3). This is executed before the main scan W is started.

That is, in the process of the pre-scanning movement R of the first and second scanning mirrors 11 and 12, the main image information light in the optical path A of the reader section is
- The second scanning mirrors 11 and 12 scan, and in synchronization with this, the photoelectric conversion element arrays S, . . .
Sn scans, and the photoelectric conversion element arrays S and xSn sequentially scan the image information of the film F from the rear to the front as shown in FIG. In other words, the light of the projected image of the main image information is transmitted from the image area on the line segment 0-0 to the image area on the line segment Q-Q via the image area on the line segment PP to the photoelectric conversion element array S, ~S.
n receives light, detects the exposure amount at points sequentially,
The received light data is input to the main control circuit 39 (FIG. 5).

The main control circuit 39 divides each point into a bright area (exposed area) and a dark area (non-exposed area) based on the manually input light reception data.

Figure 10 shows an example of a light reception data matrix in which all the points (12 x 17 points in this example) received by each element of the photoelectric conversion element array 51xSn are divided into bright areas and dark areas, and the diagonally lined points are is the bright part,
Blank point areas indicate dark areas.

For convenience of explanation, the coordinates (addresses) of each point are numbered 1 to 17 from the left column to the right column, and rows 1 to 12 from the top row to the bottom row.
The number row is specified using the X-Y coordinate formula. a-all-b
-b lines, c-c lines, and dd lines are four lines that specify additional image information addition areas in the main image information screen specified by the screen area specifying means 37a, 37b, 37c, and 37d. This corresponds to the cursor line, and the point area surrounded by each line corresponds to the additional image information addition area.

Also, the main control circuit 3 is controlled by manual means 41 (FIG. 5).
The number of points required to record the desired additional image information such as the date and characters entered manually in 9.

The main control circuit 39 controls the aa line, bb line, and c line of the received light data matrix.
- Find out whether or not there is a continuous 3-point part made up of non-exposed points where the additional exposure point is possible in the area surrounded by the c line and the dd line, that is, the area designated for addition of additional image information, i.e. search do.

In this embodiment, the priority order when searching for non-exposed points is (1, 1), (1, 2), ... (1, 17) from the left of the first row of the received light data matrix. ), then move to the second line (2, 1) from the left.
- Search for points up to (2, 2) and (2, 17) in the same way from the left until the last line, and end the search at the last point (12, 17). do.

Therefore, the a-a line corresponding to the additional image information addition designated area -
The point search order in the point area surrounded by line ``b-b line''c-'c edge line-dd line starts from (5, 6), (5, 7) ・ (5, 8) ... (5 ,14
), (6,6) ・ (6,7) ... (6,
14), (7,6) ・ (7,7〉 ... (7
,14), (8,6) (8,7) ... (
8, 13), and the last one is (8, 14).

In this example, three consecutive unexposed areas in the X coordinate direction in the point area surrounded by the a-a line, the b-b line, the c-a line and the dd line are (6, 10) and (6 , 11) There are two addresses: (6,12) and (7,6) (7,7) (7,8).

Among these numbers, the addresses (6,10), (6,11), and (6,12) of the former are searched and specified by the main control circuit 39 as the additional image information addition position according to the above-mentioned priority order.

In addition, if the recording direction of the additional image information is specified in the Y-axis direction of the received light data matrix, in this example, there are three consecutive non-exposed areas in that direction (5.7), (6,7).
The address (7, 7) is searched and specified as the additional image information addition position.

Regarding the point search, there is a mode in which the point address (12, 17) is the starting point and the process proceeds in the reverse order of the above-mentioned case where the point address (1, 1) is the starting point,
It is also possible to change the priority order, such as a mode in which the 1st to 12th rows are advanced with row priority, such as (1, 1), (2, 1), (3, 1), etc.

In order to further improve the search accuracy, the photoelectric conversion element array S1
It is also possible to take measures such as increasing the number of points divided when ~Sn scans, or increasing the number of optical sensors.

As described above, the image area specifying means 37a, 37b, 3
7c, 3', 7d, within the specified screen area of the main image information, it is possible to perform a recording process in which additional image information is added without causing any overlap with the main image information within the area. When it is found that there is a space, the first and second scanning mirrors 11 and 12 move to the main scan W to perform exposure scanning of the main image information on the photosensitive drum 15. The signal input to the light emitting element array 22 of the additional information exposure device 21 is controlled so that the surface portion of the photosensitive drum 15 corresponding to the additional recording space portion is exposed to the additional image information.

This allows the main image information screen 1 to be displayed as shown in the example in Figure 11 above.
A recording material P is output in which additional image information 102 is automatically controlled and recorded in a screen area portion 103 specified in advance for 01 and in a space portion that does not overlap and avoids the main image information portion of that area portion. be done.

Next, a case will be described in which it is found that no additionally writable space portion exists.

In this case, in the point area corresponding to the additional image information addition area surrounded by the a-a line, the bb line, the c-a line, and the dd line in the received light data matrix of the example in FIG.
There is not enough non-exposed area points (recording capacity) necessary to record the desired additional image information such as date and characters manually entered into the main control circuit 39 by the input means 41 (Fig. 5), and if recording is forced, the main This is a case where the image information and the additional image information overlap.

Now, if the number of points required for additional writing is 4, then in the received light data matrix of the example in Fig. 10, the a-a line-b-b
The points in the area surrounded by the line "ca line - dd line" are (5, 6) (5, 7) ・ (5, 8) in priority order
- Even if (8, 13) (8, 14) is searched, the addresses of non-exposed points consisting of four consecutive points are not detected.

At this time, the main control circuit 39 determines that there is no additionally writable space, and a buzzer or L button sounds to indicate this.
The display means 43 (FIG. 5), such as an ED display, is activated and recording of image information is stopped. That is, the first and second scanning mirrors 11 and 12 immediately return to the retracted home position (FIG. 2) after the previous scan is completed. The electrostatic latent image of the image information of the film F that has been exposed and recorded on the photosensitive drum 15 is not developed by controlling the developing bias of the developing device 17 to be turned off. In other words, the recorded material for which recording has failed is not output.

In this case, the designation of the additional writing location is changed and image information recording in the additional writing mode is executed again.

■Other postscript information recording means The postscript information exposure device 21 shown in the example of FIGS. 6, 7, and 8 is arranged at a required position in the generatrix direction of the photosensitive drum 15 in accordance with the coordinates of the postscript image information addition designated area by the screen area designation means. This additional information exposure device 21 is configured to move and drive the hess light, and as shown in FIGS. It is also possible to have a structure in which the drum 15 is fixedly disposed in parallel with the generatrix direction of the drum 15 without a moving mechanism.

Prediction of individual light-emitting elements arranged in...J
Exposure lens 231 that focuses 2n of emitted light and exposes the surface of the photosensitive drum 15...23n is a light emitting element foreseen,...
The additional information exposure device 21 is arranged in one-to-one correspondence with the photosensitive drum 15 at a predetermined interval.
The photosensitive drum 15 is fixedly disposed parallel to and facing the photosensitive drum 15.
This allows additional image information to be recorded without moving the device 21 over the entire length region in the generatrix direction.

A slit plate 24 is arranged between each light emitting element and the exposure lens, and restricts the light emitted from each light emitting element from going around to the adjacent exposure lens.

Although it requires more exposure lenses than the mobile device in the previous example, it does not require a moving mechanism, so the structure is simple.

Also, during the pre-scan R, the photoelectric conversion element array S, "-y
The light reception data regarding the exposure amount at each point of the main image information detected by sn (FIG. 1) can also be used as development bias control information in AE (automatic density adjustment) and the like.

The present invention can be applied to microfilm reader printers for obtaining positive copy images from negative original images and for obtaining positive copy images from positive original images, and can also be applied to plain paper copying machines, electrofax copying machines, display devices, etc. Applicable.

(Effects of the Invention) As described above, according to the present invention, in the addendum recording mode, for the roughly specified addendum information addition screen area, the writeable space portion in the area is automatically searched, and the search space portion is automatically searched for. Since the necessary additional image information is recorded on the image, there is no need to carefully identify and specify the additional recording location, and the additional recording processing operation is facilitated and speeded up. Moreover, there is no possibility of recording failure or re-recording due to duplication of the main image information portion and the additional image information portion, and economical efficiency is also improved. - When an automatic search for a writable space section finds that there is no writable space section, a warning to that effect is issued and the recording operation of the device is stopped, thereby preventing recording failures.
