Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides an image area in which image information is recorded, and control information for recording image information or retrieving image information in the image area. The present invention relates to a search device for an image recording device that is used in an image recording device that records or searches for images using a recording medium provided with a control area and searches for predetermined image information.

[Prior Art] Reader printers have been proposed that are capable of recording images on electrophotographic films such as microfilms, projecting the recorded images, and copying them onto receiving paper.

An electrophotographic film is formed into a band shape, and both ends of the electrophotographic film are wound up in layers around a winding shaft and housed in a cassette. Here, the electrophotographic film can be driven by rotating the take-up shaft. Blip marks are attached to each image area on the electrophotographic film. This grip mark is read and counted by a photo sensor, and by starting the drive from the beginning of the electrophotographic film and counting, the electrophotographic film is moved to a predetermined position (recording, projection or copying position). Can be positioned.

The drive of the electrophotographic film is controlled by control information recorded on a magnetic tape. The magnetic tape is continuously connected to the leading edge of the electrophotographic film, wound together with the electrophotographic film in layers onto a winding shaft, and housed in a cassette.

In other words, when a cassette is loaded into the League Printer, the control information recorded on the magnetic tape is first read into the storage device within the League Printer, and then the drive and recording of the electrophotographic film is controlled based on this read control information. are doing.

The control information includes shooting/non-shooting information indicating a shooting flag, status information indicating whether or not it is the beginning of a file representing a set of related image frames, a) IJ butte, status information consisting of a flag indicating discontinuity, file information, and discontinuity. Contains address information.

By the way, when recording image frames, it is common to record a plurality of image frames in succession. After recording the plurality of image frames, the original document is discarded, so it is necessary to confirm whether or not the images have been recorded reliably. In this case, conventionally, control information corresponding to each image frame has been manually searched and displayed for confirmation.

[Problem to be solved by the invention] However, if there are many image frames to be recorded at a time, it takes time to check them, and if the image frames recorded in one cassette are checked by automatic feeding, etc. , it is not possible to distinguish between the image frame recorded this time and the image frame recorded before the previous time, and the work is time-consuming.

In consideration of the above-mentioned facts, the present invention provides a search device for an image recording device that can improve the recording and verification work efficiency by sequentially displaying only the newly recorded image information after newly recording the image information. The purpose is to obtain.

[Means for Solving the Problems] A search device for an image recording device according to the present invention includes an image area in which image information is recorded and control information for recording image information in the image area or retrieving image information. A search device for an image recording device that searches for predetermined image information and is used in an image recording device that records or searches for images using a recording medium having a control area for recording, the image recording device for the recording medium. loading state detection means for detecting the loading state of the recording medium; identification means for identifying image information newly recorded after the loading state detection means detects that the recording medium is loaded; and identified image information. and display means for sequentially displaying.

[Operation] When the recording medium is loaded by the loading state detection means, the image information recorded from this point on in the control area is identified by the identification means.

When recording of the image information is completed, only the newly recorded image information after loading the recording medium is sequentially displayed by the display means.

In this way, after a series of recording operations, only the newly recorded image information can be identified and displayed without being confused with previously recorded image information, making it easier to confirm the recording. Confirmation work can be performed reliably.

The light incident on the second mirror 48 is incident on the third mirror 50 and is reflected toward the lens 54. When the incident light enters the lens 54, it is reduced by the lens 54 and sent to the process head 52.
The light passes through and is irradiated onto the electrophotographic film 32. As a result, the image of the original is formed as an electrostatic latent image on the electrophotographic film 32, and then developed by a developing device (not shown), and the image of the original is recorded on the electrophotographic film.

In order to project the image recorded on the electrophotographic film 32 onto the screen 24, the fourth mirror 62 is moved to the position shown by the solid line in FIG. It is moving to position along the direction. Light from a light source 56 is irradiated onto the back side of the electrophotographic film 32 through a lens 58 and a mirror 60. This light from the electrophotographic film 32 passes through the process head 52, is magnified by the lens 54, and enters the third mirror 50 as shown in FIG. 3 or 4. The light incident on the third mirror 50 is transmitted to the second mirror 4
8 and is incident on the second mirror 48. The light incident on the second mirror 48 is reflected toward the screen 24, and the image recorded on the electrophotographic film 32 is projected onto the screen 24.

When copying an image recorded on the electrophotographic film 32, the fourth mirror 62 moves to the position shown by the solid line in FIG. 2, and the scanning mirror 64 and scanning mirror 66 move toward the front side of the reader printer 10. It's moving. lens 58,
Light from the light source 56 irradiated onto the back side of the electrophotographic film 32 via the mirror 60 passes through the process head 52, is magnified by the lens 54, and enters the fourth mirror 62. This light is the light that has passed through the image recorded on the electrophotographic film 32, and is reflected downward by the fourth mirror 62. The light reflected by the fourth mirror 62 is incident on the scanning mirror 64. scanning mirror 6
The light incident on 4 is reflected toward scanning mirror 66,
The light is incident on the scanning mirror 66. These scanning mirrors 64
．． By moving toward the rear side of the reader printer 10, the image recorded on the electrophotographic film 32 is scanned. This scanned light is transmitted to the fifth mirror 68
and is reflected by the fifth mirror 68 toward the surface of the photoconductor of the photoconductor drum 70 . The photoreceptor of the photoreceptor drum 70 has already been entirely charged by the charging corona charger 72, and the surface of this photoreceptor is irradiated with light, so that the image of the electrophotographic film 32 is formed as an electrostatic latent image on the photoreceptor. Ru. The photosensitive drum 70 is rotating clockwise in FIG. 2 in synchronization with the movement of the scanning mirrors 64 and 66, and this rotation forms an electrostatic latent image on the surface of the photosensitive member. The photosensitive drum 70 with the electrostatic latent image formed on the photosensitive member is further rotated, a developer is applied by the developing roller 78, and the electrostatic latent image is visualized. The photosensitive drum 70, with the developer attached to the photosensitive member and the electrostatic latent image visualized, further rotates clockwise in FIG.

On the other hand, the image receiving paper 84 in the paper feed tray 86 is removed by the take-out roller 92.
The sheet is taken out from within the paper feed tray 86 and inserted between the photosensitive drum 70 and the transfer corona charger 82 by a pair of transport rollers 94, 98, 100. The developer attached to the surface of the photosensitive member of the inserted image-receiving paper 84 is adsorbed by the transfer corona charger 82, and the image of the electrophotographic film 32 is formed on the image-receiving paper 84. As a result, the image on the electrophotographic film 32 is transferred to the image receiving paper 34.

The image receiving paper 34 to which the image of the electrophotographic film 32 has been transferred is conveyed to a conveyor belt 108, fixed by a pair of fixing rollers 110, conveyed by a pair of conveyor rollers 112, and discharged onto a handle 104 and a paper discharge tray. .

Next, format control of the reader printer 10 of this embodiment will be explained. In the league printer 10, the document table 2
The original placed on the paper 6 is not recorded randomly on the electrophotographic film, but is recorded based on a predetermined format. This predetermined format is automatically set.

In this embodiment, the number of image frames 130 that can be recorded on one cassette of electrophotographic film 32 is 1000 frames, so the automatically set format is divided into 5 frames to create 200 files. . The manuscript to be recorded is defined as one file, for example, one patent specification, and the same file number is input and recorded at the time of recording work.

If one file consists of 5 pages or less,
Read the beginning of the unregistered file and process head 5
The printer is positioned at the recording position No. 2, and recording is performed sequentially from page 1. In this case, an area for 5 frames is secured in advance on the electrophotographic film 32, so if one file has, for example, 3 pages, an area for 2 frames will be available (see the chain line in Figure 14). ).

Next, if one file consists of six or more pages, the beginning of the first unregistered file is read out, positioned at the recording position of the process head 52, and the first to fifth pages are read out. Record sequentially. Next, the second unregistered file is searched again, and the images from page 6 onward are sequentially recorded. In this case, as shown in FIG.
Although they are discontinuous on 2, a flag indicating that they are the same file and consecutive pages is stored. From then on,
If one file has a large number of pages, a third and fourth file is created, and each of these is stored as a continuous and identical file. As a result, when adding to the same file, even if the data is physically discontinuous (the order of shooting on the electrophotographic film 32 is discontinuous), by reading the data on the magnetic tape 33, it becomes one continuous file. When searching using a search key, images can be projected in order from the first frame to the last frame of one file.

Next, a case will be described in which additional recording is performed on a file in which all pages are composed of three pages.

First, by key operation on the keyboard 36, the file No.
Enter. The control device 170 determines whether or not the same file number exists based on this manually entered file number 1, and if the same file exists, the images are recorded in order from the beginning of the file. Determine whether or not there is. In the above case, as shown in Figure 14, no images are recorded from the 4th frame onwards, so these 4
Record a new image starting from the frame. Thereby, the electrophotographic film 32 can be used without waste. Also, since it is divided into 5 frames in advance, the number of discontinuous frames is within 200 (the total number of frames is 1000 frames, so l O001
5=200), the storage capacity can be reduced, and the search time can be shortened.

Note that the format can be changed freely by operating the format key 158 of the keyboard 36. For example, when recording one patent specification as one file, 50 files are recorded in units of 10 pages. All you have to do is define the file.

In addition, the automatically set format is also 5 in this embodiment.
It is not limited to frame units, but may be in the range of 3 frames to 10 frames, preferably 3 frames to 6 to 8 frames. In addition, in this embodiment, the above-mentioned number of settings was preset before delivery regardless of the type of industry to which this device is applied, but the setting value that is automatically set according to the type of document in the type of industry to which this device is applied is set by the user. It may be determined as follows.

Next, the case of image retrieval will be explained according to the flowchart of FIG. 16.

This routine is executed every time the search key 164 (right sender-166 or left sender-168) is turned on.

When the search key 164 is turned on, it is determined in step 200 whether the current operating state of the control device 170 is the search mode. If you are not in search mode, step 20
2, it is determined whether or not the search key 164 is turned on following the numeric keypad 154 of the keyboard 36. If the search key 164 is not turned on after pressing the numeric keypad 154, the search operation is incorrect, so an alarm is displayed in step 204 and the routine ends.

On the other hand, when the search key 164 is turned on following the numeric keypad 154, the control device 170
The operating state is switched from the currently executing mode to the search mode, and the search range is set in step 208. This search range can be entered using the numeric keypad 154 and the search key 164.
For example, if the search key 164 is turned on following the 1 key, the entire file No. 61 will be set as the search range, and the skip key (numeric keypad 154) will be set as the search range.
When the last digit is designated as 1 using the numeric keypad 154 by the combination of the key on which 0"-" is displayed and the numeric keypad 154, all files whose last digit is 1 are set as the search range. In the next step 210, right feed key 1
66 is turned on, and when the right feed key 166 is turned on, the electrophotographic film 32 is transported so that the first frame of the search range is displayed on the screen, and the left feed key 1 is
When 68 is turned on, the electrophotographic film 32 is conveyed in step 214 so that the last frame in the search range is displayed on the screen.

On the other hand, when it is determined in step 200 that the current operating state of the control device 170 is the search mode, the process proceeds to step 216, where it is determined whether or not the right feed key 166 is turned on. When the left feed key 168 is turned on, the image is conveyed one frame to the right, and when the left feed key 168 is turned on, it is conveyed one frame to the left.

As a result of the above, when the search key 164 is turned on following the numeric keypad 154, the search range specified by the numeric keypad 154 is set, and the electrophotographic film 32 is transported so that the first or last frame of the search range is displayed on the screen. After switching to the search mode, the display screen changes one frame at a time each time the search key 164 is turned on.

In the next step 222, it is determined whether or not the search key 164 is on, and if it is determined that the search key 164 is on, the specified image (the image of the first or last frame in the search range, the search It is determined whether a predetermined time (for example, 1 second) has elapsed since the image was displayed by reading the count value of a counter that counts the time since the image (one frame advanced by the key 164) was displayed on the screen. This count value is counted by a counter that is interrupted when the image is displayed on the screen and starts the counting operation of the counter in step 236, as shown in FIG. If the predetermined time has not elapsed, the process returns to step 222, and if the predetermined time has elapsed, it is determined in step 226 whether or not the search key 164 has been turned off.

When it is determined that the search key 164 has been turned off, the count value of the counter at the time when the search key 164 was turned off is read, the read time image is displayed, and the mode is switched to an automatic feed mode in which the image is switched to the next image.

In this way, by turning off the search key 164 after the required time has elapsed since the image is displayed on the screen, the system switches to the automatic forwarding mode, and after automatically projecting the screen for a predetermined period of time, the next screen is automatically displayed. Can be switched.

Further, the projection time can be changed by changing the time period during which the search key 164 is turned on.

FIG. 18 shows an interrupt routine f that is interrupted when the clear/stop key 152 is turned on. In step 230, it is determined whether or not an alarm is being displayed. If the alarm is being displayed, the alarm is not displayed in step 232. After stopping, the current operating mode is switched to the previous operating mode in step 234. Therefore, when the search mode is switched to the automatic feed mode and the clear/stop key 152 is then turned on, the mode is switched to the previous operation mode, that is, the search mode.

Although the projection time of one image in the automatic feed mode is taken as the operation time of the search key 164, an operation key or an operation knob may be provided to separately set the projection time. In this case as well, the time during which the operation key or the operation knob is continuously operated becomes the display time.

Next, a function for checking whether or not image recording has been performed reliably will be explained according to the flowchart of FIG. 19.

In order to operate this function, first, while operating the function key 156, the 7 numeric keypad 154 is operated (step 300). Next, in step 302, each image frame 130
Control device 1 determines whether or not the photographed flag is set.
Judging from the data stored in step 70, then regarding the image frame 130 set in step 304,
It is determined whether the cassette 42 has been loaded and then set. Thereby, only the image frames 130 photographed after the cassette 42 was loaded this time can be specified. In the next step 306, the identified image frame 130 is assigned a file number.

Projection is performed in physically continuous order from the beginning of the electrophotographic film 32 regardless of the situation. Thereby, search information such as page marks can be added while viewing the projected image.

Note that the cassette 42 in which the image has been photographed can be copied to another cassette, but in this case, a duplication machine (not shown), which is a copying-only machine, is used. In this duplication machine, the number of copies is recorded, and when the recorded number of times reaches a predetermined number, copying is not possible, thereby preventing deterioration of the photographed image.

Further, in this embodiment, the image recording device of the present invention is applied to the league printer IO, but it can also be applied to devices that digitally record images such as optical files and facsimile images other than the above-mentioned electrophotography.

[Effects of the Invention] As explained above, the search device for an image recording device according to the present invention, after newly recording image information, sequentially displays only the newly recorded image information, thereby improving the workability of checking the recording. It has the excellent effect of improving
