Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to an image information processing device, and more particularly to one that uses a roll-shaped microfilm contained in a cassette as a recording medium on which images are recorded.

[Conventional technology 1] In office automation, which aims to improve the efficiency and productivity of office departments, the establishment of document storage and retrieval systems plays an important role.

An effective means for this purpose is the use of microfilm. Conventional microfilms include roll film, aperture card, microfilm and microjacket forms.

■Microfilm is a roll of film that is continuously reduced in size and photographed.It is stored in a reel or magazine, and is used as a microreader or reader using the search code etc. imprinted at the same time as the photographing process. Search and restore by printer. ■Aperture cards are cards of an appropriate size (usually 18M cards) with a square window (aperture) and a microfilm attached thereto. Using the preset code on the card as a clue, the necessary card is manually or mechanically removed and restored using an aperture card reader. ■
Microfilm is a sheet-like film (filas)
First, the materials are photographed directly with a special camera, and the necessary materials are searched for using the reference numbers attached to the fils as clues, and restored and deciphered using a fish reader. ■Micro jacket is made of roll film taken separately.
The film was cut into 12-frame film strips and inserted into a transparent sheet jacket.

[Problem to be Solved by the Invention 1] However, in any of the above usage modes, there is a drawback that the copying device that copies the original document and the search device (microreader) that searches for the photographed frames are separate entities. When searching, it is necessary to manually look at image information enlarged one by one or search for the photographing code, which results in a lack of quickness and wastes a lot of effort and time.

Also, information that identifies the photographed frame (frame number, code, etc.)
The information is usually imprinted on the microfilm itself, so information cannot be added to or modified later.

To add or modify information later,
There is a method that inputs and saves information that identifies each photographed frame into an external memory, but this requires memory for the images recorded on multiple microfilms (cartridges), so it is difficult to use a microfilm cartridge. The disadvantage is that the larger the number, the more memory is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the various drawbacks mentioned above, and its purpose is to speed up the search for image information using a cassette-shaped image recording/search medium that is easy to handle.

Another object of the present invention is to provide information (
(including frame numbers, codes, etc.).

The purpose is to be able to make corrections.

Still another object of the present invention is to make it possible to search for image information that has already been copied even when copying a document, and to make it possible to copy into an unrecorded area even when searching.

Another object of the present invention is to make the entire device compact and simple in construction.

[Means for Solving the Problems] Therefore, the present invention provides an image processing system that includes a photographic film section in which images are photographed and recorded frame by frame, and a recording section that stores photographic and recorded information of the photographic film section as digital data. a cassette containing a recording/retrieval medium, a mechanism for mounting the cassette into the apparatus main body, a means for driving the image recording/retrieval medium, a reading means for reading digital data in the recording section, and the reading means. memory means for temporarily storing the digital data read by the
A photographing means for photographing an image, a projection means for projecting the photographed image, a specifying means for directly or indirectly specifying a desired frame and whether to photograph or project, and a memory means for storing data specified by the image specifying means. The apparatus is characterized by comprising a control means for controlling the driving means to move the specified frame to a photographing position or a projection position based on digital data stored in the memory, and for controlling photographing or projection.

The recording section is preferably composed of a magnetic tape.

Further, the digital data preferably includes information as to whether the frame has been photographed or not, and re-photographing of the photographed frame is prohibited.

Further, the cassette preferably has two shafts.

[Operation] When digital data in the recording section of the recording/retrieval medium is read by the reading means, this digital data is stored in the memory means. The control means controls the driving means from the digital data stored in the memory means and the data designated by the image designation means. In the case of photographing, the control means drives the image recording/retrieval medium, moves the specified frame to the photographing position, and causes the frame to photograph an image. In the case of photographing, the control means drives the image recording/retrieval medium, moves the designated frame to the projection position, and projects the image photographed at that frame onto a screen or the like.

[Effect of the invention 1] According to the present invention, since the image recording/retrieval medium is built into the cassette, it is easy to handle and store, and the position of the tape body can be detected by specifying the address of the frame from the outside. However, since the tape running is controlled based on the control commands of the control/calculating means, it is possible to quickly search for a specified frame, and it is also possible to record the film section and information corresponding to the frame of the film section. By using a tape body that is integrated with the recording section, the information in the recording section is transferred to an external memory, and the recorded contents of the recording section can be updated by manipulating the stored contents.
This has the advantage of being able to enrich the "Table of Contents", and furthermore, this enrichment of the "Table of Contents" can contribute to speeding up searches.

Further, when the recording section is composed of a magnetic tape, the contents stored in the recording section can be easily updated.

Furthermore, if the above-mentioned digital data includes information as to whether or not the frame has already been photographed, re-photographing the already photographed frame is prohibited, so another image may be imprinted on the same frame again. It is possible to eliminate such things.

Furthermore, when the cassette is a cassette with two shafts, there is no need to provide a complicated mechanism such as a tape pull-out mechanism on the apparatus main body side, and the structure on the apparatus main body side becomes simple.

The effects of the present invention are more pronounced when electrophotography is used than in a microfilm system using conventional silver salt photographic materials. In other words, in the case of silver halide photographic materials, if unexposed areas are exposed to light, or if they are developed without being exposed, information cannot be recorded in those areas.
After recording information (image exposure, development, and fixing) using a portion of the roll film, the remaining blank area is left unexposed and undeveloped for use in projection, etc., and then as needed. It is necessary to record additional information in the margin, but
During use, it is extremely difficult to completely shield the projection light from entering this blank area, and if the film is replaced with the blank area left intact, it may cause damage during replacement or storage. It is extremely difficult to completely block light from hitting this blank space. In particular, when a roll film with blank areas is placed on a reader to search for the area to be projected, in order to search without exposing the blank areas to light, it is necessary to rely on completely non-optical search methods. This is extremely disadvantageous both in terms of equipment and in practical terms, and the fact that it is not possible to move frame by frame and visually search for images has almost no value as a practical machine. Furthermore, if you are reading with a reader and advance frame by frame without knowing that there is a blank area after the last frame of the photographed section, that area will be exposed.To prevent this, Even if various methods are possible, all of these methods require troublesome additional work at the time of photographing, and are almost impossible in practice.

On the other hand, in the electrophotographic method, the photosensitive material can be reused by cleaning it regardless of whether it is exposed or unexposed, and even after development or before fixing, so there is no need for the above-mentioned light shielding, and it is possible to It is possible to use a photosensitive material in which only a portion of the image is recorded and a blank area is left. Therefore, image information is partially recorded on a roll film-like electrophotographic material, the remaining blank area is left untouched for use, and additional information is recorded in the blank area when the need arises. It is possible to do so. In other words, there is no need to continuously record one piece of information during recording, and even if requests for recording different types of information occur randomly, it is possible to organize and record each type of information. It is something. And this recorded information is
The photographic and recorded information recorded in the recording section can be freely accessed.

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

The RAM 8 functions as a buffer for storing information recorded in the magnetic recording section In via the magnetic recording/reproducing means 3 and recording stored information in the magnetic recording section 1m via the magnetic recording/reproducing means 3. Equipped with 10 is the microcomputer 6,
Manual input means such as a keyboard is used to input commands or information, and numeral 11 is a position detection means for detecting a specific position in the length direction of the tape body l and outputting a detection signal to the CPU 7. The computer 6, particularly the CPU 7, controls the drive means 2 based on commands and information input from the above-mentioned means.
It gives control commands to control the feeding of the tape body l, controls the magnetic recording/reproducing means 3, and further controls the image forming means 4.

Further, 14 is a magnetic information output means for displaying a list of the stored contents of the RAM 8 outputted via the CPU 7, and is provided in a preferred embodiment.

When recording the original 5, a command is given to the CPU 7 by operating the manual input means 10, the image forming means 4 is controlled by the CPU 7, and the image information of the original is imprinted on the film portion If set at a predetermined position. At the same time, information related to this image information, such as image information data such as a frame number, shooting date, unique search code, and a simple comment, is written into the RAM 8 by operating the manual input means IO.

However, in addition to inputting by individual operation, if, for example, an employee number, document number 9 date, etc. constitute sequential data, it is also possible to record them automatically instead of manually. of the set paper tape or magnetic tape (
The data is sequentially written into the RAM 8 in conjunction with digital (sequential) data. In this case, the manual input means 1O may be operated by simply activating the activation switch.

When searching, operate the manual input means 10 to specify information (code, date, frame address, etc.) for specifying the desired photographic frame 13; this specific information is included in the image information data related to the image information described above. ) and a search command. The CPU 7 controls the driving means 2 to feed the tape body l, and when it comes near a predetermined search position and the position detection means 11 accurately detects the specific position, the feeding is stopped. At this position, the V image information can be displayed by the image information output means 12. At this time, if there is any addition or modification of related information regarding the retrieved image information, that data can be added or updated in the RAM 8 by the manual input means IO.

It is possible to record while searching, or conversely, to search while recording, which is an operation that combines the above two operations.

When the RAM 8 is accessed by the manual input means 1O to write or rewrite the memory contents, the stored contents of the RAM 8 are accessed at the final stage of a series of operation operations.

The information is recorded in the magnetic recording section 1m via the magnetic recording/reproducing means 3.

FIG. 2 is a schematic diagram of a preferred embodiment.

A long tape body 1 with a constant width has both ends attached to winding shafts 21° and 22.
It is fixed to the paper and can be wound into a roll.

The take-up shaft 21 is rotationally driven by the take-up motor 23 only in the clockwise direction in FIG. ). On the other hand, the take-up shaft 22 is rotationally driven by the take-up motor 24 only in the counterclockwise direction in FIG.
can be sent in the right direction).

Specifically, the tape body 1 has a width of 8 mm or 16 mm, and includes a transparent end portion 25 with one end fixed to the winding shaft 21, and a long magnetic tape portion 26 continuous with the transparent portion 25.
and continues to the magnetic tape section 26.

Perforations 2 at fixed pitch intervals on one end in the width direction
7 and a transparent film portion 28.

The transparent film portion 28 is formed by sequentially forming a transparent conductive layer and a transparent photoconductive insulating layer on a transparent support mainly made of polyester, and constitutes a photoreceptor for electrophotography. Further, this transparent film portion 28 has polarizing properties. The above-mentioned tape body 1 has three consecutive regions, and the method of making it is based on the above-mentioned tape-like body of a transparent support mainly made of polyester. Preferably, it is formed by coating techniques.

Image information of the document material is imprinted onto the transparent film section 28 by the electrophotographic device 4 serving as an image forming means. Two perforations 2 of transparent film section 28
7. Frame 29 (l frame) where the area between 27 and 27 is one
corresponds to As is well known, the electrophotographic apparatus 4 includes a charging section, an exposure section, a developing section, and a fixing section.

On the other hand, several detection mechanisms are arranged along the feeding path of the tape body l. 30 is a first edge detection element for detecting the first edge 26e of the magnetic tape section 26; 31 is a first edge detection element for detecting the first edge 26e of the magnetic tape section 26;
32 is a tape speed detection generator for detecting the feeding speed of the tape body l; 33 is a perforation detection light receiving section for detecting the perforations 27;

34 is a polarized light source, which guides light into two systems. One is a system in which the optical path of the light emitted in the feeding direction of the tape body is changed by a reflection mirror 35, and the light is made almost perpendicular to the tape body l, and then incident on the first end detection element 30 provided on the opposite side. Part 2
5 and the magnetic tape section 26, that is, the beginning end 26e of the magnetic tape section 26. Others are
This is a system that irradiates perpendicularly to the traveling locus of the perforations 27, and the perforation detection light receiving section 33 is irradiated via a polarizing filter 36 provided on the opposite side of the tape body 1.
The perforation 27 is used to guide light to detect the presence of the perforation 27. The reason why the polarizing filter 36 is passed through the second system is to utilize the polarization property of the transparent film section 28, so that the irradiated light from the light source 34 is passed through the transparent film section 28.
When the light passes through the light and enters the light receiving section 33, the amount of light is reduced to almost zero. Therefore, the polarization plane of the polarization filter 36 is provided in a conjugate relationship with the polarization plane of the transparent film portion 28. Although the polarized light source 34 is shared by the two systems, it may be provided separately, or a light emitting diode (LED) may be used as the light source.

Furthermore, in this example, since the film portion 28 has a polarizing property, this property is utilized, but other detection means for the film perforation 27 may be used. For example, a method in which a light source and a photomultiplier tube (Photomultiplier tube) are placed on the same side of the film section 28, and the presence or absence of the par-7-hole silane 27 is detected by the light reflected from the film surface. It is. Furthermore, although the perforations 27 are used here as an information source for specifying frame positions, the information source is not limited to perforations. In other words, -V For example, if you print a blip mark (optical mark) in a predetermined code format in advance,
A method of optically detecting this may also be used. Alternatively, a method may be used in which an optical mark is recorded during development processing (in this case, the unphotographed portion is detected by the distance from the final mark).

The magnetic head 31 and tape speed detection generator 32
are fixed to the same fixed seat 37, and the solenoid 38
When energized, the fixed seat 37 moves in a direction substantially perpendicular to the feeding path of the tape body I, and both the magnetic head 31 and the tape speed detection generator 32 come into pressure contact with the tape body I.

In conjunction with this movement of the fixed seat 37, the lever member 39 is driven, and the tape pad 41 fixed to the pad seat 40 acts to press the back surface of the tape body l toward the magnetic heald 31.

The arrangement of the mechanical system described above is conceptually illustrated, and an example of a specific arrangement is shown in FIG. Third
The figure shows the film loading section of this device viewed from above. The tape body l is wound in advance around two take-up reels 42 and 43 and stored in the cassette case 44. The tape body l placed in the cassette case has a structure almost similar to, for example, a compact cassette magnetic tape for music or a cassette tape for a VTR (
Hereinafter, the cassette case 44 containing the tape body 1 will be abbreviated as a "cassette 45"). As shown in FIG. 4, which is a cross-sectional view taken along line IV-IV in FIG.
48 and stretched between both tape guides 47 and 48. Along the running path of the stretched tape body 1, a polarized light source 34 and a light receiving element body 49 in which a first end detection element 30 and a perforation detection light receiving part 33 are integrated are arranged opposite to the polarized light source 34, and then , an electrophotographic copying device 4 is arranged. The electrophotographic copying device 4 has an optical system 4 including a copying lens.
a, a charging chamber 4b, an exposure chamber 4c (located at a position corresponding to the optical system 4a), a developing chamber 4d, and a fixing chamber 4e arranged in sequence.

Next to the charging chamber 4b, via a guide post 50,
Rotatably supported tape speed detection generator 32
The roller part is located. The magnetic head 31 and tape pad 41.41 are located next to this roller section.

Note that in order to extract the image information, the transparent film section 28 is directly irradiated with a separate projection light source (not shown), and projected onto the screen via appropriately arranged lens means and optical path changing means. .

Preferably, the lamp provided in the fixing chamber 4e (often an infrared lamp is used) is also used.

Details of the projection means are disclosed, for example, in earlier applications filed by the same applicant as the present application.

The magnetic head 31 is connected to a magnetic recording/reproducing circuit 56 and to the CPU 7 via an I10 port 57. When recording on the magnetic tape unit 26, data from the RAM 8 is transferred to the CPU 7. The signal is transmitted from the magnetic recording/reproducing circuit 56 to the magnetic head 31 via the I10 port 57. During playback, the flow of data is the opposite, and the data flows from the magnetic tape section 26.
The recorded contents are read by the magnetic head 31, and the magnetic recording/reproducing circuit 56.110 port 57. Via CPU7, R
Write to AM8. Note that the solenoid driver circuit 5 that supplies current to the solenoid 38 is connected to the I10 port 57.
8 is connected, and deenergization/energization of the solenoid 38 is controlled by a signal from the CPU 7.

The tape speed detection generator 32 is connected to a driver circuit 59 that drives the take-up motor 23 of the take-up shaft 2l, and provides a tape speed signal. The perforation detection light receiving section 33 is connected to the pulse counter 60 and also to the driver circuit 59° and the winding motor 2 of the winding shaft 22.
The pulse counter 60 is connected to a driver circuit 61 for driving the perforation 27, and provides the pulse counter 60 with the pulse count of the perforation 27, while also providing a signal to the driver circuits 59 and 61 to stop the photographic frame 29 at the correct position.

Driver circuits 59.61 are connected to motor current detection circuits 62.63, respectively. The motor current detection circuit 62 provides a signal to the I10 port 64 via the signal line S6, and from the I10 port 64, the signal line 31. S3. S5 connects the driver circuit 59 to input a feedback signal. On the other hand, the motor current detection circuit 63 is connected to the I10 port 55 via the signal line S7, and the I-
/0 port 55 connects the signal line S2. S4 is connected to input the feedback signal to the driver circuit 61.

The pulse counter 60 is connected to an i10 port 65, and three control signals SH and SU are connected to the I10 port 65.

On the other hand, a circuit based on the fact that the tape body l is made into a cassette is also provided, and the cassette loading switch 68 is connected to the cassette 45.
(Fig. 3) automatically closes the switch contact when loaded. This contact closing signal is transmitted via ■10 boat 67
It is input to PU7.

Further, the CPU 7 outputs a signal to the cassette lock circuit 70 via the I10 port 69, and when the device is operating, the cassette 45 is transferred to the cassette loading chamber 46 (FIG. 4).
A mechanical stop should be provided to prevent it from being removed. Furthermore, as a function of the stop means, when there is a change in the contents of the RAM 8 even at - degrees, the magnetic tape section 2
It is necessary to copy the contents of the RAM 8 to the cassette 45, and this is also to prevent the cassette 45 from being taken out without being copied.

Now, in this image information recording/retrieval device, an electronic control system is devised to stop one frame corresponding to one perforation at a specific position with high precision during recording or retrieval. Qualitatively speaking, when a desired frame is produced from the current stop position, the frame is initially advanced at high speed, but as it approaches the desired frame, it switches to low-speed advance.
Detect the perforation corresponding to the desired frame,
This is a control that immediately stops feeding and stops it at a predetermined position with high precision.

FIG. 5 is a circuit diagram for explaining this, showing the perforation detection light receiving section 33. Driver circuit 59 for forward rotation
(comprising a control section 59a and a drive section 59b), a reverse rotation driver circuit 61 (consisting of a control section 61a and a drive section 61b), and motor current detection circuits 62 and 63.

In the perforation detection light receiving section 33, the bar 7 oration irradiation light is received by two photodiodes PDi and PD2. Photodiode PDI.

The PD2 is connected to the two outputs of the operational amplifier OPI so that the polarities are opposite to each other, receives the perforation transmitted light with a time difference, and outputs a voltage waveform in which trapezoidal pulses are continuous in the positive and negative directions. Details of this are shown in FIG. That is, the photodiodes PDI and PD2 are planar photodiodes separated and insulated at the center, and the width of one photodiode is slightly larger than the width of the perforation 27. When the transparent film portion 28 is fed from left to right in FIG. 6(a), the photodiode PDI alone outputs a trapezoidal pulse in the positive direction as shown in FIG. 6(b). On the other hand, from the photodiode PD2, a pulse having a polarity opposite to that of the above-mentioned pulse is generated from the photodiode PD1. The output is point symmetrical about the central junction of PD2. This 2
When the two pulses are converted from current to voltage by the operational amplifier OPI and combined, a voltage waveform in which the trapezoidal pulses swing continuously in positive and negative directions is obtained, as shown in FIG. 6(c). The approximate midpoint of this waveform from positive to negative corresponds to zero potential, and the temporal position of this zero potential is
It corresponds to the junction of DI and PD2, in other words, to the center position of the perforation 27.

This positive/negative waveform signal is input to the pulse counter 60 and counts up or down by l. In this example, the count number and frame position correspond, and if the count number in the counter circuit 60 is n, it means that the frame is currently at the n-th frame position in the transparent film section 28 starting from the end of the magnetic tape section 26. corresponds to

The waveform signal is also input to a zero potential detection circuit 59a, which is a control section included in the driver circuit 59, and a zero potential detection circuit 61a, which is a control section included in the driver circuit 61. The zero potential detection circuit 59a is used when the transparent film portion 28 is sent leftward, and detects a zero cross from negative to positive.

On the other hand, the zero potential detection circuit 61a
is used when the signal is sent in the right direction (rewind direction), and detects zero crossing from positive to negative. Analog switches 71.72 are connected to the output portions of each zero potential detection circuit 59a, 61a, and each analog switch 71.72 is controlled based on a signal from the CPU 7, and controls the transparent film portion 28. OF when sending at high speed
F is turned ON during low speed feed. Specifically, FET and CMO3 semiconductor switching elements are used as analog switches, and based on the comparison results in CPU7,
O when the frame before the target frame is counted
N is given. When the center position of the perforation corresponding to the target frame is detected, a zero potential signal is output, and the signal is applied to the drive unit 59b or 61b to deenergize the motors 23 and 24 of the drive units 59b and 61b. death,
It is stopped precisely at the center position of the perforation 27.

The drive unit 59b, which rotates the motor 23 in the normal direction when sending the tape body l to the left, converts the target constant speed feed signal 5Itr set in the CPU 7 into an analog quantity by the D/A converter 73, and sends the operational amplifier OP2. A current is supplied to the motor 23 through the motor 23. This motor drive section 59b has a resistor 75. Servo system 7 consisting of analog switch 76 and generator 77
8 is connected to the winding motor 23 by the generator 77.
is controlled to maintain a constant feed rate. This is used when reading or writing information on the magnetic tape section 26 during forward rotation, and is used to receive a control signal (signal S) from the CPU 7.
5) turns on the analog switch to realize constant speed feed.

The drive unit 61b, which reverses the motor 24 when feeding the tape body l in the right direction, converts the right feed signal S2 inputted and set to the CPU 7 into an analog quantity by the D/A converter 74, and outputs the signal to the motor 24 via the operational amplifier OP3. A current is supplied to 24. The configuration of this drive section 61b is similar to the drive section 59b for normal rotation except that the servo system 78 is removed. Signal S
4, the analog switch 72 is controlled based on the output of the zero potential detection circuit 61a when coming one frame ahead and stopping at the desired frame position.

The motor current detection circuit 62 connected from the motor 23 via the comparator OP4 includes an RC integration circuit, and is configured to detect when an overcurrent flows to the take-up motor 23 (for example, so that rotation of the motor 23 is physically prevented). (at the end of winding, etc.)
The buffer 79 outputs a signal (S6) to stop the motor 23. In other words, this RC integration circuit does not detect a short-term excessive current at the time of starting the motor 23, but instead obtains a signal S6 from the buffer 79 when the excessive current persists for a certain period of time or more. On the other hand, from the motor 24 to the comparator OP
The motor current detection circuit 63 connected through the motor 5 also has the same configuration as the motor current detection circuit 62, and outputs a signal (S7) to stop the motor 24 due to an overcurrent. Further, the effect of the RC integration circuit is the same as that in the case of overcurrent detection of the motor 23.

Next, the operation of the soil composition recording/retrieval device will be explained based on the general flowchart of FIG. 7 and the detailed flowcharts of FIGS. 8A to 8F.

As shown in FIG. 7, when the cassette 45 is loaded and started, the contents of the magnetic tape section 26 are read and all this information is stored in the RAM 8 (subroutine #l). Next, there are two selectable modes, and you can select one as appropriate.

The first mode is a mode for recording document information, in which document information is imprinted at a desired frame position (hereinafter referred to as a frame address) on the transparent film section 28, and information related to this document information is manually inputted. This is a mode in which data is written into the RAM 8 by operating the keyboard IO (subroutines #2 and #3). In this mode, there may be only one frame, multiple frames, consecutive frames, or frames located at discrete positions. The second mode is a mode for searching recorded document information, in which a frame address is input using the keyboard 1O, a recorded frame specified by the frame address is stopped at a predetermined position, and the image information output means 12 (first This is the mode for displaying images or making hard copies (subroutine #4).
. At this time, if you want to add or change related information for the recorded frame, use the keyboard IO to RQ.
Rewrite the contents of M8 (subroutine #5). If this data is not added or changed, the contents of the RAM 8 remain unchanged.

It is also possible to combine the above first mode and second mode. That is, it is a combination mode in which the first mode is executed and then the second mode, or conversely, the second mode is executed and then the first mode is executed.

When you exit the first mode, second mode, or combination mode, rewind the tape and rewind the RA.
The stored contents of M8 are transferred to the magnetic tape section 28 (subroutine #6). Finally, the cassette 45 is taken out and the operation is completed.

More specifically, with reference to FIG. 2, the cassette 45 is loaded into the cassette loading chamber 46 of the apparatus (step St). Cassette loading switch 68 automatically turns 0N
L (step S2), this signal is input to the CPU 7 via the I10 port 67, and the device itself becomes ready for operation. Next, the tape body I is preferably driven based on this signal. Alternatively, the driver circuit 61 may be started by a start command input from the keyboard 10. The tape body 1 is sent to the right by the winding motor 24 (
In step S3), when the first end 26e of the magnetic tape section 26 is detected by the first end detection element 30, the running of the tape body l is stopped (steps S4, S7). If it is not detected, it continues to drive to the right (step S5.
S3. S4 loop), or the tape body 1 is wound up to the limit on the right winding shaft 22, taking into account the possibility of detection failure.
When the motor does not move (step S5), the motor current detection circuit 63 operates (step S6) and stops the motor 24 (step S7).

In any case, when the tape body 1 stops running, the motor 23 is then driven to send the tape body 1 leftward at a constant speed (step S8). At this time, just before the motor is driven, the solenoid 38 is energized and the magnetic head 31. The tape pad 41 and the tape speed detection generator 32 (the roller portion thereof) are pressed against the tape body l. The recorded contents of the magnetic tape unit 26 are read by the magnetic head 31, and the RA is read through the magnetic recording/reproducing circuit 56, the I10 port 57, and the CPU 7.
M8 is pressed (step S9). In this case, this reading is performed regardless of whether the cassette is a completely new cassette or a cassette that has already been photographed, that is, regardless of whether image information data has been written on the magnetic tape section 26.

Without detecting the boundary between the magnetic tape section 26 and the transparent film section 28, the tape body l continues to run as it is (Stella 7'5IO), and the perforation detection light receiving section 33
When the first perforation 27 of the transparent film portion 28 is detected, the tape running is stopped (step 5ll). Accordingly, the magnetic head 31. The tape pad 41 is retracted. For convenience, the address of the frame corresponding to the position of the first perforation 27 will be referred to as the first address. Therefore, the count value n in the counter circuit 60 itself represents the frame address and indicates that the frame is currently at the n-th frame position. However, it should be noted that the method of specifying the frame address is not limited to this, as other methods may also be considered.

Next, if the camera is in recording mode or photographing mode and is stopped at a specific frame, it is determined whether to write or rewrite data related to that frame (step 312). addition.

If correction is necessary, input the data using the keyboard IO. The contents of RAM 8 are updated (step 513).

When the RAM 8 is updated even once through a series of operations, the CPU 7 generates a cassette lock signal and sends it to the cassette lock circuit 70 via the I10 port 69.
is activated so that the cassette cannot be mechanically removed from the cassette loading chamber (step 513). This is R
This is to prevent the risk of taking out the contents of the magnetic tape unit 26 without rewriting them to the same contents when the contents of AM8 are changed.

The next step is to move the desired frame to a predetermined position (predetermined copying position or predetermined image output position). The frame address is input into a register in the CPU 7 by operating the keyboard 10 (step 514). Since the current position of the frame is set in advance in another register in the CPU 7 via the counter circuit 60, 110 port 65, the CPU 7 compares these two pieces of data to decide whether to send it to the left or to the right. A determination is made as to whether or not the vehicle should be sent in that direction (step 315). Note that at this time, a start command from the keyboard IO may be used in addition to inputting the frame address data. In this example, only the frame address input is used as a start signal. Depending on the judgment of the CPU 7, one of the driver circuits 59 and 61 is driven (step S1
6. S17, 318). At the same time, a judgment is made as to whether to run at a high speed or at a low speed (step 519). If the address difference exceeds a predetermined constant value, the drive will run at a high speed (step 521), and if it is below, the drive will run at a low speed (step 521).
Step 520). If this address difference falls below the predetermined value during travel, the vehicle automatically switches to low speed travel (step S22, 520).

When it comes one frame earlier, the zero detection section 59 shown in FIG.
a or 61a is activated and stops accurately at the frame corresponding to the designated address (step 523).

In the next step, a human determines whether or not to continue tape running (step 524). If the search is not to be continued, recording in the specified frame is performed (step 525). A document is placed in a predetermined position, and while the frames of the transparent film section 28 charged in the charging chamber 4b are sequentially fed one frame at a time, the optical system 4a is operated to connect the exposure chamber 4c, the developing chamber 4d, and the fixing chamber 4c. 3), known electrostatic copying is carried out. These series of operations are performed in ROM9 (
The CPU 7 issues appropriate commands and controls exposure and film feeding operations according to a program built into the camera (FIG. 1). However, the basic command for copying is performed by operating the keyboard IO.

Usually, before or after this copying operation, data related to this recorded image, such as the photographing date, two classification codes, and the title, are written into the RAM 8 from the keyboard 10.

The next step is a post-processing step that takes place after executing the search mode, recording mode, or combination mode and before attempting to remove the cassette.

First of all, corrections and changes to RAM8 - Chinnage hlf,
Since the storage contents of the RAM 8 and the storage contents of the magnetic tape unit 26 are the same, the cassette can be taken out as is (step S26.527).

However, if there is an access even at − degrees, rewriting is necessary.

A code for recording the contents of the RAM 8 on the magnetic tape section is entered manually (step 527). Depending on the CPU7
energizes the driver circuit 61 and rewinds the tape body l to the right by the winding motor 24 (step 528). Of course, at this time the vehicle was running at high speed. The count value of the count circuit 60 counts down (Step 529), and as soon as the count output (the same count value is also present in the register in the CPU 7) becomes zero, the tape speed is decelerated based on the instruction from the CPU 7 (Steps S29, 530). (Step 531
), and when the first end 26e of the magnetic tape portion 26 is detected (step 532), the running is stopped (step 53).
3) Let it happen. Accordingly, the magnetic head 31 etc.
8, the magnetic tape section 26 is pressed into contact with the magnetic tape section 26. Thereafter, the tape is sent in the forward rotation direction (leftward) by the take-up motor 23 (step 534), and while being fed, the data from the RAM 8 is passed through the CPU 7, the I10 port 57, and then the magnetic recording/reproducing circuit 56 receives electric current. The data is converted into a file and recorded on the magnetic tape portion 26 by the magnetic head 31 (step 535).

The recording on the magnetic tape unit 26 is completed when the first perforation 27 is detected, that is, when the counter 60
When the count value becomes 1, a command is issued by the CPU 7 to stop the running of the tape body 1 (step 536). At the same time, CPU7 has I10 port 69
A signal for disabling the cassette lock circuit 70 is derived through the cassette lock circuit 70, and the cassette lock signal is turned off (step 83).
6). As a result, the mechanical locking state is released, and the cassette 45 can be taken out from the cassette loading chamber 46.

In the above description of the embodiment, the tape body 1 is shown in FIG.
This is a tape body having a magnetic tape section 26 at one end, followed by a transparent film section 28 for electrophotography having perforations 27. As shown in FIG. 9(b), the magnetic tape portion 26 does not need to be provided over the width of the tape body 1, and may be formed in a narrow stripe shape in consideration of the recording density and the magnetic head. Further, as a modification of the tape body l, as shown in FIG. 9(C), a perforation 27 is formed on one side in the width direction, and a thin magnetic recording portion 26 is formed on the other side over almost the entire length. You may also do so. Preferably, the magnetic recording section 26 is based on a transparent film and is coated with a magnetic coating.

By the way, when using the tape body l shown in FIG. 9(C),
It can also be implemented in other ways. The first example is a method in which the magnetic recording section 26 directly below the photographed frame is used as a storage area for information (which may include address information) related to the photographed frame. The advantages are that the information input to the magnetic recording section 26 can be addressed by itself, reducing the need for providing perforations 27;
In addition, there is no need to provide the RAM 8 with a storage capacity corresponding to the total number of frames. In other words, in the latter case, writing or rewriting information is not necessarily stored in RAM.
8, the input information can be written directly to the magnetic recording section 26 via a small capacity buffer memory.

The second example is a method that combines the above embodiment with the first example. First, the magnetic recording section 26 from the beginning of the tape body 1 to a predetermined length is set as an information recording area for all frames to be photographed.

On the other hand, deletions, modifications, additions, etc. may be made to the magnetic recording section corresponding to each frame (normally, it may be the magnetic recording section directly below each frame, but if a certain positional relationship is defined, it is not necessarily the section immediately below). write only the correction data (of course in the area following the address data)
. In this method, only when this correction data exceeds a predetermined amount (such as a limit based on recording capacity), the data is transferred to a buffer memory, and transferred from the buffer memory to the all-frame recording area. Since the data is transferred for each frame, the buffer memory only needs to have a small capacity. According to the above two example methods, Daikichi fiRAM, which requires a storage area for each individual frame,
This method has the advantage of requiring only a very small capacity buffer memory compared to a method in which all information is written out, and is therefore more economical.

FIG. 10 shows another modification of the tape body l.

Figure 1θ(a) corresponds to that in Figure 9(c),
FIG. 9(b) corresponds to that of FIG. 9(a). All of them are of a type that does not require barflation in the transparent film portion 1r. This is because detecting the through holes in the transparent film portion if is quite difficult and requires special measures as shown in the above embodiments.

FIG. 11 shows an outline of the configuration of an apparatus using the tape body l shown in FIG. 1O(b). This device corresponds to the device shown in FIG. 2, and the same or equivalent parts as in FIG. 2 are denoted by the same reference numerals, and redundant explanation will be omitted.

A hole 100 is provided in the magnetic recording section 1m whose tip is fixed to the winding shaft 21 at a short distance from the tip.

This hole 100 is detected by a light emitting diode 101 and a photoelectric conversion element 30 for receiving light, and indicates the recording start point (or reproduction start point) of the magnetic recording section 1m.

102 is a rotary encoder. After loading the cassette, the roller section of the low reencoder 102 is always held in pressure contact with the tape body l.
In addition to detecting the traveling speed of the vehicle, it is also used to detect the frame address. The output of the rotary encoder 102 is input to the counter circuit 60 and also to the frequency-voltage conversion circuit 103 (FV converter). F/V converter 103
For example, when the tape is running at high speed, the high frequency pulse from the rotary encoder 102 is converted into a high voltage, and this generated voltage is applied to the driver circuit 59. The rotation of the take-up motor 23 is controlled by this control voltage.

The other configurations and operations are roughly the same as those of the previous embodiment, and will therefore be omitted.

This device has the advantage of eliminating the difficulty of detecting perforations in the transparent film portion if.

In the above embodiment, the information regarding the photographed frames is transferred from the magnetic recording section 1m to the RAM 8, and the contents of the RAM 8 are manipulated by external input means. It is not limited to what is used, and for example, a dry silver film may be used.

Furthermore, although the RAM 8 is a semiconductor memory included in a microcomputer, it is not particularly limited to use within the microcomputer. It may also be a combination of a microprocessor or dedicated digital control circuit and conventional semiconductor memory.
