, a drying section 2408 , and a fixing section 2410 .

The electrophotographic film 16 is placed in the charging/exposure section 2404.
A protruding frame 2412 is formed that abuts the edge of one piece. The inside of the protruding frame 2412 is a charging/exposure chamber 2414 that penetrates in the horizontal direction (vertical direction in FIG. 2(B)).
B) a corona wire 2416 extending in a direction perpendicular to the plane of the paper;
Corona electrodes 24 located on both sides of corona wire 2416
18 are arranged. The lens 26 is provided with a mirror ThJ2 on the surface opposite to the surface on which the protruding frame 2412 is formed.
It is attached to the process head 24 via 6A. Note that the optical axis of the lens 26 coincides with the center of the protruding frame 2412.

A projecting frame 2420 having an opening width slightly narrower than that of the projecting frame 2412 is formed in the developing section 2406 . A developing electrode 2422 formed of a metal plate is disposed inside the protruding frame 2420, slightly inward from the end surface of the protruding frame 2420. A space surrounded by the protruding frame 2420 and the developing electrode 2422 is the developing chamber 24 . Development electrode 242
Openings equal to the width of the developing electrode 24220 are formed between the upper and lower parts of the projecting frame 2420 and the developer inlet 2426 and the developer outlet 2428, respectively.

The developer inlet 2426 communicates with a developer supply tank (not shown), and a predetermined amount of developer is supplied to the developing chamber 24 through the developer inlet 2428 during development.

The developer is made by dispersing fine powder toner particles in a solvent, and a charge control agent is added so that the toner particles are easily charged negatively. The developer outlet 2428 communicates with a developer receiving tank (not shown). The developer is configured to be circulated between the developer receiving tank and the developer supply tank by a known pump. In addition, the compressed air is discharged from the developer inlet 2426, and the developer after development is quickly υ from the developer outlet 2428.
will be released.

Recesses 2442 are formed on both left and right sides of the projecting frame 2420. A part of the recess 2442 is opened and communicated with a pressure reducing mechanism such as a known suction pump.
42 serves to suck up leaked developer. In addition,
In FIG. 2(A) and FIG. 2(B), illustrations of piping connecting each device, etc. are omitted.

A protruding frame 2446 is formed in the drying section 2408.

The protruding frame 2446 is formed on the upper part and both left and right sides excluding the lower part, and has an opening width wider than that of the protruding frame 2412. A wall 2448 is formed inside the projecting frame 2446 slightly inward from the end surface of the projecting frame 2446. A recess 2450 is formed between the wall 2448 and the protruding frame 2446. Projection frame 2446, wall 2448 and recess 24
The space surrounded by 50 is used as the drying chamber 24 and the power supply circuit 52. A recess 2450 located at the top of the wall 2448 is open and serves as a hot air outlet 2454 .

The fixing section 2410 is formed by a frame portion of the projecting frame 2446 on the left side in the drawing and a projecting wall 245 at the end of the process throat 24 on the left side in the drawing.
6, and the space is a fixing chamber 24.
It is said to be 58. The fixing chamber 2458 is provided with a strobe xenon lamp 2460° reflector 2461 and a light receiving element 2460A for light emission confirmation, and heat fixation is performed by the flash of the xenon lamp 2460.

The opening width of the fixing chamber 2458 is the same as that of the drying chamber 24 and the tA circuit 5.
The opening width is made wider than the opening width of No. 2.

Note that the end faces of the projecting frames 2412, 2420, and 2446 are located on the same plane. In addition, the charging/exposure chamber 24

As shown in FIG. 2(B), a presser plate 2466 is provided on the front surface of the process head 24. The holding plate 2466 presses the electrophotographic film 16 against the gutter 24 for processing, thereby accurately positioning the electrophotographic film 16 and improving the adhesion between the electrophotographic film 16 and the process head 24. When the electrophotographic film I6 moves, the pressure of the presser foot 2466 is released.

(Exposure amount detector) Next, the exposure amount detector 49 will be explained in detail according to FIG. The reflected light from the original 30 is received by the light receiver l original, and a voltage proportional to the amount of received light is applied to the integrator 13 via the amplifier 132.
4. Integrator 134 integrates this voltage and provides it to the non-inverting input terminal of comparator 136. Integrator 134
The integral value is reset between the shutter 47 and the shutter (when No. 3 is supplied).

Therefore, when the shutter 47 is opened at the time of exposure, a high (H) level signal is output from the comparator 136 and is supplied to the input port door 6. The rising edge of this signal is the automatic exposure control signal ABC. The processing of the automatic exposure control signal ABC by the microcomputer 68 will be described later.

(Power-off detection circuit) Next, the power-off detection circuit 53 will be explained in detail according to FIGS. 4 and 5(A).

A zero-crossing point of the voltage of the commercial AC power supply 138 is detected by a zero-crossing detection circuit 140, and a zero-crossing signal Tτ (see FIG. 5(A)) is supplied to a clear terminal of an up counter 142. The up counter 142 has its count value cleared by the rise of the zero cross signal T, and restarts counting the clock signal. This clock signal is a frequency-divided clock signal used by the CPU 70, and its period is 1.6 m5ec in this embodiment. When the count value reaches 11, AND gate 144
The output becomes H level, is differentiated by the differentiating circuit 146, and its rising edge is detected, and the mono multivibrator 14
8 and inverted by the inverter 150, the non-maskable interrupt signal NMI (see FIG. 5(A))
The signal is supplied to the input port door 6 and the drive circuit 88 shown in FIG.

Therefore, if the next zero-crossing signal Tτ is not supplied to the up-counter 142 even after 1.6X11=17.6m5ec has passed after the zero-crossing point of the commercial AC power supply 138 is detected, ';! The 1B disconnection detection circuit 53 outputs a non-maskable interrupt signal NMI.

Normally, the negative pulse period of zero cross signal Tτ is lQmse
c, the count value is cleared to 6, and the non-maskable interrupt signal NMI is not output.

The output signal of the AND gate 144 is supplied to the differential circuit 1 power supply circuit 52 via the inverter 151, and when the output signal of the AND gate 144 rises, that is, the count value is 1.
2 is detected. Then, it is shaped by a monomultipipe rake 154, inverted by an inverter 156, and supplied to the manual port door 6 shown in FIG. 1 as a reset signal RESET (see FIG. 5(A)).

Therefore, the non-maskable interrupt signal NMI
After 15m5ec has elapsed after outputting the reset signal RE
SET will be output. This reset signal RE
SET is an interrupt signal to the CPU 70.

The processing of the non-maskable interrupt (i.e. NMI and reset signal RESET will be described later).

(AC power control circuit) Next, according to FIG. 4 and FIG. 5(B), the drive circuit 80
The AC power control circuit 81, which is a component of the following, will be explained.

This AC power control circuit 81 uses a tritic 158 to control the power supplied to the illumination light source 28 in two stages, strong and weak. In this embodiment, the illumination light source 28 has a stable light amount and a long service life. A halogen lamp is used, which has the characteristic of a long lamp.

Zero cross signal T from the zero cross detection circuit 140
7 (see FIG. 5(B)) pulse fall is counted by the presetup counter 160. The preset value of the preset counter 160 is determined by the voltages of the input terminals A, B, C, and D, and is 11 in this embodiment. Then, it is set by the rise of the output pulse of the AND gate 172 (preset signal). That is, when the count value of the presetup counter 160 reaches 15 (at this time, the zero cross signal Tτ is at low (L) level).
, the output of the AND gate 170 becomes H level, the AND gate 172 is opened, and then the output of the AND gate 170 becomes H level.
When the level is reached, a preset signal is input through the AND gate 172, and the count value is preset to 11.

Therefore, the count of negative pulses in the zero-cross signal T becomes 15, and the output of the AND gate 170 becomes H level only when one zero-cross signal T is at L level.

The weak lighting signal WL from the output port door 8 shown in FIG.
When the level is reached, the AND gate 174 is opened, and the H level from the AND gate 170 is passed through the AND gate 174 and the OR gate 176 to the gate pulse signal CP (fifth level).
The signal is supplied to the triac 158 as shown in Fig. (B) (see Vi), and the tritic 158 is fired at the zero cross point. For this reason, only half the wavelength of the two wavelengths of AC is the illumination light fi2
8 Flow (Figure 45 (B) A, C.

(see D), 1/4 of the power when the tritic 158 is shorted is supplied to the illumination light source 28. Furthermore, since the ignition occurs at the zero cross point, no noise is generated in other circuits.

If the strong lighting signal SL is set to 1-level, the AND gate 17
8 is opened and the zero cross signal ZC passes through the AND gate 178.
, to the triac 158 via the OR gate 176, and the trihook 158 is fired at each zero crossing point so that a full wave of alternating current flows through the illumination source 28. In this way, the power supplied to the illumination light source 28 can be controlled in two stages using the strong lighting signal SL and the weak lighting signal WL without generating noise. This lighting control will be described later.

By changing the preset value of the preset up counter 160, the power supplied to the illumination light 'tA28 can be set to 1/n (n is a natural number) of the power supplied to the illumination light 'tA28 in the case of strong lighting. . This AC power control circuit 81 can also be applied to, for example, a thermal development device, a thermal transfer device, etc. when the load is a heater. This is because there is almost no thermal variation in the load.

(Outline of Processing by Image Information Processing Apparatus) FIG. 7 shows a detailed diagram of the operation keyboard 66. Also, the 13th
Figures (A) to (C) show general flowcharts of processes performed by manual key operations from the operation keyboard 66, and various processes will be explained with reference to FIG.

In the following, the absolute address refers to the position of the frame corresponding to the blip mark 21 on the electrophotographic film 16 from the magnetic tape 1B side. In this embodiment, the code consists of a numerical set of a large section number (folder F), a medium section number (item J), and a small section number (page P), for example, 100. 2.
Represented as 3. This major division number is a number that divides folders, and the size of the number is unrelated to the arrangement order. In addition, the medium section number and small section number indicate the relative address from the beginning of the large section, and the above example (
100, 2, 3) indicates the third piece from the beginning of the second medium section. Further, in this embodiment, the file mark is a mark consisting of a four-digit number, and is used to search for related documents regardless of the classification number.

The relationship between these absolute addresses, codes, and file marks will be explained in detail later.

In FIG. 13, when the power is turned on, the work area and output signals of the RAM 74 are initialized (step 200). In this state, the search copy mode is set. When a cassette is loaded into the cassette loading section 90 (step 202), the cassette loading detector 62 is turned on, and the information recorded on the magnetic tape 18 is stolen by the microcomputer 68 via the recording/reproducing head 60.
It is stored in RAM74.

<Folder registration> Folder registration refers to registering folders that are distinguished by major division numbers, such as 0, 100, etc. 5.
If 10 is registered, five items of each IO page are created in the folder numbered 100.

A folder with a total of 50 pages will be created.

To explain this according to FIG. 13, when the FORM key 100 is turned on in step 206, step 208.2

Next, in step 206, the numeric keypad 104 is operated to select, for example, 100. 5. 10 and key manual step 2
This code is memorized in step 22, and displayed on the code display section 102 in step 224.0 Then, in step 206, when the FORM key 100 is pressed, the code is displayed in step 208.
．． Steps 210, 212, 214, and 218 are set, the mode is set to registration mode, and the manually entered code is displayed blinking in step 220. In other words, the operator is asked to confirm whether the code is correct.

Next, when the FORM key 100 is pressed again in step 206, the process advances to steps 208, 210, and 226, and the input folder is registered.

In this way, the FORM key 100 functions as both a mode change key and an entry key.

As will be described later, the same applies to other function keys. Therefore, the operation becomes easy and the operation keyboard 66 can be simplified.

Then in step 206 CLEAl? /5TOP key 1
Pressing 06 advances to steps 208 and 228 and clears the registration mode. Then, in step 224, the displayed code is cleared.

<Photography> Next, a case in which a document is photographed and recorded on the electrophotographic film 16 will be described.

In step 206, the shooting location is designated as 100.2, for example. In this case, it is specified that the first page of item 2 in folder number 100 is to be photographed. This code is stored in step 222;

Next, set the next original and select PH0TO in step 206.
When key 108 is pressed, steps 20B and 210 are performed as before.
, 234.238 to 242.228 to 232.

Note that if the code is specified as 100 instead of 100.2, one inflated image will be performed in order from the first unpossessed image (empty) page of folder number 100.

Further, when the code and the number of empty pages are blinking as a result of executing step 232, a file mark can be attached to the frame that will be next most shaded.

This is done by manually inputting the file mark number on the numeric keypad 104 and then pressing the STO key 110.

For example, if the number 20 is entered in step 206, steps 208, 222, and 224 are executed, and then, if the STO key 110 is pressed in step 206, steps 208.
Proceed to 210, 212, and 244, and set this number 20 as the file mark number.

Next, set the file mark submode in step 2.

It is displayed on the display 64. This (is the count display section 103
This means that there are pages that can be projected only in the direction in which the number of pages increases (towards the right of the electrophotographic film 16 shown in FIG. 5).

Here, "projectable" means that there is an object that is most closely shadowed without any mistakes within the search range.

During image projection, press the right 5 EAR of the 5 EARCH keys 112.
When the CH key 114 is pressed, the search is performed in the direction of increasing the number of pages, and when the left 5 EARCH key 116 is pressed, the search is performed in the direction of the decrease in the number of pages.

Next, return to step 206 from step 262, and press the right S E A RCH key 114 again to return to step 20.
Proceed to 8.210.212.256 and electrophotographic film 1
6 is sent to the next projectable page. Then, it is projected (step 258), and 100.2.2 )( is displayed on the LED display 64. ]( is the current position of the electrophotographic film 16 (the frame position at the optical axis 35 shown in FIG. 1). ) indicates that there are pages that can be projected in the left and right directions.

In step 206, press the right S E A RCH key 114 again.
When you press , steps 20B, 210.256~
260 processing is performed, and 100.2.3) is displayed on the LED display 64. ] indicates that there are pages that can be projected only in the direction in which the number of pages decreases.

In addition, in step 206, if the 5EARCH key 1 is pressed for a certain period of time or more,
If 12 is pressed, scrolling is performed. That is, proceeding from step 260 to steps 262 and 264,
If it is within the search range, step 2 after a certain time interval.
Repeat the processes from 56 to 260 to sequentially perform projection and LE.
The information is displayed on the D display 64. This point will be explained in detail later.

Next, the case of searching and projecting using file marks will be explained.

Similarly to the above, press the CLEAR/ST'OP key 106 to turn off the display on the LLED display 64. Next, the file mark number is input using the numeric keypad 104. This causes the processing of the process head 24 in step 222.2.

Next, press the RCL key 120 to specify that the input number is a file mark. That is, the process advances to steps 208 to 212.26G and 268, and the previously input number is set as the file mark recall number. Next, this file mark is displayed on the count display section 103 (step 270), and the process returns to step 206.

If you press the 5EARC)i key 112 here, the target to search for is Forgoo. The process is the same as when no file mark is attached, except that instead of specifying the first page of the item, the search range is a projectable page having a file mark that matches the input file mark recall number.

Next, Folgu. A case will be described in which a search range is specified by item or page, and only pages with specified file marks within the search range are searched and projected.

As above, press the CLEAR/5TOP key 106 to
The display on the ED display 64 is turned off. Next, the file mark number is entered manually using the numeric keypad 104. This causes the processing of the process head 24 in step 222.2.

Next, press the RCL key 120 to specify that the input number is a file mark. That is, the process advances to steps 208 to 212.266.268, and the last manually entered number is set as the file mark recall number. Next, this file recall number is set to 0, and this file mark is then displayed on the count display section 103 (step 270), and the process returns to step 206.

Next, in step 206, a search range is specified.

For example, enter 100.2. This causes step 22
2.224 processing is performed and 100 is displayed in the code display section 102.
．． 2 is displayed.

Then, in step 206, press the right SEA RC11 key.
When you press 14, steps 208 to 212.25 are performed as above.
Perform the processing from 0 to 254, and then press the right 5EARCH key again in step 2O6 to proceed to steps 208 and 210.
．． The process advances to 256 and the electronic photographic film 16 is sent to the first page with file mark number 20 within the search range. The subsequent processing is the same as the process when no file mark is attached, except that only those with file marks within the search range are searched.

<copy> Next, the case of making a copy during a search will be explained.

For example, 100. 2. Assume that page 2 is projected. Next, the number of copies is input using the numeric keypad 104. This causes the processing of steps 222 and 224 to be performed. Next, when the C0PY key 122 is pressed, step 206
~210.272 and the code 100. 2.2
and the number of copies. For example, if the number of copies is 2, 02 is displayed on the count display section 103. Next, copies are made (step 2 RAM 74), and if the remaining number of copies is not O (step 276), the above-mentioned step 27
2.2 Repeat the processing of RAM 74. When the copying is completed, the process advances to step 260, and the code and projectable direction are set to LE.
It is displayed on the D display 64. Step 262 then returns to step 206. Note that if only the C0PY key 122 is pressed without specifying the number of copies using the numeric keypad 104, only one copy will be made.

Also, when specifying the number of copies, the blank key 118
Press to perform group copy. That is, for example, code 100. 2. When the blank key ttS is pressed at position 2 and then the C0PY key 122 is pressed, all the frame images 22 included in 100.2 and shaded one by one are copied one by one.

<Changing or Deleting a File Mark> Next, a case in which a file mark is changed or deleted during a search will be described.

For example, 100. 2. When page 2 is being projected, enter the number 50 using the numeric keypad 104.

This causes the processing of steps 222 and 224 to be performed.

Next, when the STO key 110 is pressed in step 206, the process proceeds to steps 208 to 212.244, and the file mark submode is set to 0, with the number 50 as the file mark number (step 246), and the code 100.
2. 2 is blinkingly displayed on the code display section 102, and the file mark number (F50) is blinkingly displayed on the count display section 103 (step 24B).

When the STO key 110 is pressed again in step 206, the process advances to steps 208, 210, 278, and 280, and the numerical value 50 is set as a file mark. In this way 100
．． 2. A file mark 50 is set on the second frame image 22.

Next, the case of erasing a file mark will be explained.

During the search, for example, the code 100. 2. If 3 nopesi are projected, in step 206 I? C.L.
When key 120 is pressed, steps 208-212.266.
The process advances to step 282 to display the 0th order code for setting the file mark erasing submode and, if this code has a file mark, on the count display section 103 (step 270).

for example, 100. 2. 3 F20 is displayed.

Next, in step 206, when the STO key 110 is pressed, the process proceeds to steps 208 to 212.244.245.24B, where the code and file mark number are displayed blinking, and the operator is asked to confirm whether the file mark number can be deleted.

Next, in step 206, when the STO key 110 is pressed again, the process advances to steps 208, 210, 278, and 284, and this file mark 20 is erased.

Ending Operation> Next, the operation after the photographing, retrieval, projection, or copying process is completed will be described.

When the REW/EJCT key 124 is pressed in step 206, the process advances to steps 208 to 212.286, and if previous photography has been performed, the process advances to step 288, where the last photographed page is projected on the screen 40 and the cassette is ejected. Ask for confirmation. Next, the code is displayed on the code display section 102.
and the End symbol is displayed on the count display section 103 (step 290). The mode is then set to rewind/eject mode (step 292).

When REW/E JECT 1 process head 24 is pressed again in step 206, step 208.21O2
294, the winding shaft 14 shown in FIG. 1 is rotated counterclockwise to wind the electrophotographic film 16 and the magnetic tape 18 onto the winding shaft 14. Next, rotate the shaft 12 clockwise to release the electrophotographic film 16 stored in the RAM 74.
information is recorded on the magnetic tape 18. Then, the magnetic tape 1B is rewound. Next, the process proceeds to step 296, where the display on the code display section 102 is turned off and the count display section is turned off! En on 03
d is displayed.0 Next, the process advances to step 298, where the cassette is raised and can be taken out. The operator then removes the cassette and turns off the power. Step 28
6, if no photography was performed, 288~
Step 290 is not executed, and the process immediately proceeds to step 292.The subsequent steps are the same as those in the case where photographing was being performed, except that there is no projection processing.

(Piece Information) Next, the specific structure of piece information will be explained according to FIGS. 9 to 12.

Figure 9 shows 100. 2. 3.200. 3. After registering the folder with 2, change the folder number 100 to 1
00. 3. 3 shows the case of extended registration. In the case of extended registration, the extended portion is registered in the unregistered area next to the registered area on the electrophotographic film 16. In addition, if a shooting error occurs due to FittA being turned off during the first shadow, the frame with the corresponding code is secured in the opposite direction from the last frame of the electrophotographic film 16. It has become. In FIG. 9, code 100. 2
．． A shooting error occurred at position 2, and the last piece, 100
This 100. 2. The piece with code 2 is photographed.

By specifying the I-most shadow code, 11 shadows can be drawn in random order on the electrophotographic film 16.

For a search, for example, when a code 200 is input, absolute addresses 7 to 10 become a searchable range as shown in FIG. 6, and these can be sequentially projected by pressing the right 5 EARCH key 114. Furthermore, if the code 100.2 is input, the absolute address 4.1000 becomes the searchable range. Further, by searching using the file mark 10, it is possible to project the frame image 22 with the absolute address 1.7. Also,
If you search using the file mark 20, you can project the absolute address 3.8.

The process of making a copy is the same as the case of projection.

FIG. 10(A) and FIG. 11 correspond to FIG. 9.

FIG. 10(A) is a folder table in which folder numbers are arranged in the order of registration. FIG. 11 is an address table in which the frames of the electrophotographic film 16 are arranged in order of absolute addresses, but in order of codes.

As shown in FIG. 12, whether it is F, J, or P is expressed by 2 bits (category FJP) in the status byte. F when FJP is 3, J when it is 2, P when it is 1
, and when it is O, it is an end mark.

Further, an absolute address is expressed in 2 bytes. The status byte 12 also includes a photographing completed flag C (1 when photographing has been completed) and a photographing error flag M (1 when photographing has been completed).

In addition, a 2-byte file mark is stored corresponding to each piece. These 5 bytes are reserved for each frame image 22 for all frames.

Since the segment FJP is represented by 2 bits, the storage capacity can be reduced.

(Method of Determining Absolute Address) Next, a method of determining an absolute address from a code will be explained according to FIGS. 10(A) and 11.

For example, code 100. 1. In the case of 3, the 10th
Looking at Figure (A), folder number 100 is the first, so look at the first F in Figure 11. Folder F has both item J and page P, so proceed to the right from F (100, 1, 1) and count the number of P by 2. The absolute address of this position is 3. In this way 100. 1.
It can be seen that the absolute address of 3 is 3.

Also, for example, code 200. 2. In case 2, if you look at Figure 10 (A), the folder number is 200.
is in the second position, so in Figure 11, 2 from the left
Look at number F. Since F has both J and P, and J has P, its position (200, 1,
At the first J on the right side from 1) (200, 2, 1)
and then go to the first P position (, the absolute address of this position is 10. In this way, the code 20
0. 2. It can be seen that the absolute address of 2 is 10.

Next, according to FIG. 14, the absolute address of the target position (destination absolute address) is set based on the current position of the electrophotographic film 16 (this absolute address is referred to as the current absolute address).
We will explain in detail how to find .

Current position is code 100. 1. 3 (Figure 11 A)
and the target position is 200. 2. 2 (FIG. 11 E) will be explained. Code 200 at the target position in step document 0. 2. 2 is input. Then, from the folder table shown in FIG. 10(A), the number from the beginning of this folder number 200 is determined. In this example, it is the second document, and the value of L is 2 (step document 2).

If the folder number is not found even after searching the folder table (step document 4), a warning is issued to the operator (step document 6) and the process returns to the main routine.

Next, set the reference position (100) of the folder to which the current position belongs.
, 1, 1) in the memory (step manuscript 8). As you will see later in the explanation, this is handled uniformly regardless of whether the destination location is in the same folder or not. This is to simplify the program. In the step document 8, the LXO value is the value of L at the current position, and is 1 in this example. The value of A is determined as the address of the first F in FIG. Therefore, the value of A is O.

Next, in step 310, since LX<L, the value of d is set to 5 (step 312), and this value of d is the first
This is based on the fact that the frame information corresponding to one frame image 22 is 5 bytes, as shown in FIG.

Next, in step 316, the values of X and C used in the subroutine of FIG. 14(B) are determined.

The value of X corresponds to 3 when FJP is F, 2 when FJP is J, and 1 when FJP is P. The value of C is 1 in this example, and as described later, the value of C is 0, which corresponds to finding the position C of the first F by proceeding to the right from the position of the mouth in FIG. The subroutine shown in Figure (B) is executed.

Since the value of C is l, step 400 to step 40
Proceed to step 2, and set the value of d (-5) to the value of address A on the memory.
) is added. The FJP shown in FIG. 12 at the updated address A becomes P when looking at FIG.
=1. Therefore, steps 404 to 40
Proceed to step 6. Since the value of X is 3 and FJP<X, the process returns to step 400. When steps 400 to 406 are repeated 10 times, the position shown in FIG. 11 is reached, and in step 406 E
The value of JP becomes 3 and the process advances to step 408.

As shown in FIG. 9, this 200. 1. Since 1 is not a shooting error, the value of M is O, and step 410
The process proceeds to step 400, and the value of C is decremented until the value of C becomes 0. Then, the process returns to step 400 and returns.

Next, in step 320, the value of d is set to 5, the value of X is set to 2, and the value of C is set to J-1. Since J is 2, the value of C is 1, which is 0.Then, in step 322, the subroutine of FIG. 14(B) is executed. As above, steps 400 to 406 are performed 2 times.
After repeating this several times, you will be in the position of the 11th drawing, step 406.
Then, the value of FJP becomes 2, and the process proceeds to step 40B. 9th
As shown in the figure, 200. 2. Since the position of 1 is M-0 without a til shadow mistake, proceed to step 410 and select C.
Decrement the value of . As a result, the value of C becomes 0, and the process returns to step 400, and then returns.

Next, in step 324, the value of X is set to 1, and the value of C is set to P-1.
be the value of Since the value of P is 2, C becomes 1 (0).Then, in step 326, the subroutine of FIG. 14(B) is executed. As above, the processes of steps 400 to 406 are
FJP when done twice.

The value becomes 1 and the process proceeds to step 408. As shown in FIG. 9, since M-0 is at this position, the process proceeds to step 410 and decrements the value of C. As a result, the value of C becomes 0, and the process returns to step 400, and then returns.

Next, in step 328, the absolute addresses (see FIG. 12) stored in addresses A+1 and A+2 are set as the value of Y. The value of Y is 10. Then, the process returns to the main routine.

In this way, 200. 2. The absolute address of 2 is Y
It can be found as the value of

Next, a case will be explained in which the absolute address of the target position within the same folder is determined.

Set the current position to 100. 2. 21 to address 1000
) and the target position is 100. 1. Set it to 3. Step originals O to 8 are processed in the same manner as described above, and the process proceeds to the left from the position shown in FIG. 11 until the first F is found. F is found at the mouth position and the value of address A on this memory is determined (A=0). Then steps 310, 31, 31
Proceed to step 6. The values of L and LX are both 1, and the value of C is O
becomes. Therefore, even if the subroutine of FIG. 14(B) is processed in step 318, the process returns from step 400 and proceeds to step 320. This is because the mouth position and the target position A are in the same folder. Step 3
At 20, the value of C becomes O, and step 4 is performed in the same manner as above.
The process proceeds from step 00 to step 324 because the mouth position and the target position A are within the same item. In step 324, the value of C is 2, and in steps 400-410
Repeat the process twice and return. Next, in step 328, the value of Y becomes 3. Then, the process returns to the main routine.

In this way, regardless of whether the destination location is in the same folder as the current location, the absolute address of the destination location can be determined using the same processing method.

The film is fed from the current position to the target position as follows.

Calculate the difference between the absolute address of the destination position obtained as above and the absolute address of the current position that has already been obtained, determine whether to feed the electrophotographic film 16 to the right or left depending on the sign of the difference, and determine the value. The electrophotographic film 16 is stopped by counting the blip mark 21 by the absolute address. In this way, the piece at the target position is sent to the position of the optical axis 35.

(Film Feed) Next, steps 240 and 250 shown in FIG. 13(C) will be explained in detail according to FIG. 15.

Move the electrophotographic film 16 to the current position (absolute address Nl)
) to the destination position (absolute address Nl). As shown in FIG. 1, the interval between adjacent blip marks 21 is 51, and the distance at which blip marks are not detected is 3.
Set to 0. S, <S.

, and the command speed for film feeding is V. The voltage to be supplied to the motor 48 or 50 is determined from this (2) and the winding diameter of the tape IO. The time integral value of the command speed V is S
shall be.

In this embodiment, when Nl > Nl, that is, when rewinding the electrophotographic film 16, the electrophotographic film 16 is rewound to address N, -1 and then reversed to wind one frame. The mechanical conditions such as inertia are kept the same to improve the stopping accuracy of the electrophotographic film 16.

First, the case where Nl <N will be explained. step 500
．． The process proceeds to step 502, and in step 520, the value of K is set to 1 in order to increment the value of N.

Next, the process proceeds to step 504, in which the electrophotographic film 16 is fed faster as the value of -IN+Nxl, which determines the speed pattern of the commanded speed V, is larger. Is this speed pattern tabulated and stored in ROM? 2, and changes stepwise as shown in FIG.

Next, in step 506, S is cleared to 0. Then, the process proceeds to step 510, where the command speed V and the electrophotographic film 1 are cleared.
A voltage corresponding to the winding diameter of 6 (determined by the value of N + ) is supplied to the motor 48 . Next, the process advances to step 512, where the value of the film feed distance S is updated. Then SkuS
, (step 514), return to step 510,
Repeat the above process. That is, if S<S, the presence or absence of the blip mark 21 is not determined. Thereby, even if dust is attached to the electrophotographic film 16, it will not be mistakenly determined as a blip mark 21. In order to improve the stopping accuracy of the electrophotographic film 16, it is necessary to stop the electrophotographic film 16 at the same time as the edge of the blip mark 21 is detected, and since there is no time to distinguish between dust and the blip mark 21, S <S, it is extremely beneficial not to read the signal from the light receiving element 56.

In the above repetition, the value of V in step 512 is updated according to the speed pattern determined in step 508.

If S≧S, the process advances to step 516, and the light receiving element 5
The presence or absence of the blip mark 21 is determined by reading the signal from 6. If the blip mark 21 is not detected, the process returns to step 510 and the processes of steps 510 to 516 are repeated.

If the blip mark 21 is detected, the process proceeds to step 518, and an abnormality in film advance is detected based on the value of ls s+l. If ls-311<1, it is determined to be normal, and N is incremented at step 520. Step 52
If N1≠Nt in step 2, the process returns to step 506 and the above process is repeated to count the number of blip marks 21.

If Nl”Nt in step 522, step 52
4 to stop feeding the electrophotographic film 16, then 0 to stop feeding the electrophotographic film 16.
Since the value is -1 in step 526, the process returns to the main routine.

Next, the case N,>N will be explained. In this case, the process proceeds from step 504 to step 528, where the value of N2 is decremented. As a result, in step 524, the electrophotographic film 16 is rewound by one extra frame and the feeding of the electrophotographic film 16 is stopped. Also, set the value of K to -1 and step 520
decrements the value of N.

After stopping the feeding of the electrophotographic film 16 in step 524, the process proceeds to steps 526 and 530, increments the value of N2, and returns to step 500e Ng -
Nl + l, the above-mentioned process for N, <N: is performed, and only one frame is sent.

Next, in step 518, if l5-s, l≧ε,
It is determined that the feeding is abnormal, and the feeding of the electrophotographic film 16 is stopped in step 532. In step 534, the feeding abnormality is displayed and an alarm such as a buzzer is sounded to notify the operator of the abnormality, and the process ends. Then, after the operator normalizes the process, the process is restarted.

In this way, since feeding abnormalities are detected every time the electrophotographic film 16 is fed one frame, abnormalities such as jamming in film feeding can be detected early, and it is possible to prevent the electrophotographic film 16 from becoming a defective product. .

(Description) Next, step 242 shown in FIG. 13(C) will be explained in detail according to FIG. 16.

In step 600, the electrophotographic film 1 is
6 is uniformly positively charged. Next, the process proceeds to step 602, in which the integrator 134 shown in FIG. 3 is reset, and in step 604, the strong lighting signal SL shown in FIG. 4 is set to H level to strongly light the illumination light a28 shown in FIG. 1. Then, in step 606, the shutter 47 is opened.

Next, in step 608, the value of T, which is a soft timer, is cleared. In step 610, the comparator 13 shown in FIG.
If the output of 6 is at L level, T is incremented at step 612. If the value of T has not reached To in step 614, the processing of steps 610 to 614 is repeated.

The value corresponds to a slightly longer exposure time than the exposure time when shadowing black paper. Therefore, if the lamp of the illumination light source 28 is not burnt out, step 610 is performed before T=T.
At this point, the output of the comparator 136 becomes H level, and the process proceeds to step 616, where the shutter 47 is closed. Then, in step 618, the strong lighting signal SL is set to L level and the weak lighting signal WL is set to H level to weakly light the illumination light source 28.

In this way, exposure processing is performed in steps 602 to 618. Next, in step 620, development, drying, and fixing are performed.
Return to main routine.

FIG. 5(C) shows a time chart of lighting control of the illumination light source 28 in the close-up mode.

When the shirt is closed, the light does not turn off but remains weakly lit.
This is to ensure a halogen cycle, prevent filament consumption and blackening of the tube wall of the illumination light source (halogen lamp) 28, and keep the color temperature constant.

If the lamp of the illumination light source 2B is burnt out, repeating steps 610 to 614 will result in T ``'' Ta in step 614, the process will proceed to step 622, the shutter 47 will be closed, and the lamp will be burnt out in step 624. is displayed and an alarm such as a buzzer sounds to notify the operator that the lamp is out, and the process ends.

In this way, lamp burnout of the illumination light a28 can be detected with a simple configuration of simply adding steps 608, 612, and 614. Alternatively, a counter may be provided to count the clock signal while the shutter 47 is open, and when the count is up, it is determined that the lamp is burnt out.

Next, according to FIG. 17, step 62 shown in FIG.
Fixing, which is part of the 0 processing, will be explained.

In step 650, a flash of light is emitted from the xenon lamp 2460, and in step 652, it is determined whether the light receiving element 2460A has received this light.

If light is received, the fixing process ends. If no light is received, in step 654, a display indicating that the lamp is out is displayed and an alarm such as a buzzer is sounded to notify the operator that the lamp is out. Then, in step 656, it is stored in the RA°M 74 that the relevant piece is unfixed. This storage is performed by storing the addresses of unfixed frames in a specific area, as shown in FIG. 10(B). This example shows that the pieces at addresses 4 and 15 are unfixed.

Since the number of unfixed pieces is generally small, a small storage area is sufficient.

Incidentally, unfixed frames may be stored by setting one bit in the status byte shown in FIG. 12.

The fixing process for unfixed frames will be described later.

(Power Abnormality) Next, interrupt processing when a power abnormality occurs will be described according to FIG. 18 (A>).

Processing is started when the non-maskable interwoven signal NMI is supplied from the power-off detection circuit 53 to the input port door 6. At step 700, the contents of the registers (including the program counter) are saved in preparation for a restart. Next, the process advances to step 702, and step 6 is performed due to a power outage.
If it is determined that the process in step 50 has not been completed, the address of the unfixed frame is stored in the RAM 74 in step 704, similar to the case where the lamp is out.

Next, the case where the power is restored will be explained according to FIG. 18(B).

Step 7 If the address of an unfixed frame is stored in the RAM 74 in the manuscript, the frame is fixed in step 734.
(including the program counter) is then restored from the point at which the power failure occurred.

Next, the above step 732 will be explained in detail according to FIG. 18(C).

In step 760, the electrophotographic film 16 is sent to the address of the unfixed frame stored in the RAM 74. Next, the process proceeds to step 762, where the xenon lamp 2460 emits a flash of light, and in step 764, the light receiving element 2460
It is determined whether A has received this light. If light is received, fixing is complete, and in step 766, the address of the unfixed frame is cleared. The process then proceeds to step 768 where R
If there are other unfixed items stored in the AM 74, the processes of steps 760 to 768 are repeated.

When it is determined in step 764 that the light receiving element 246OA does not receive light, steps 654 to 17 in FIG.
656 processing is performed.

(Magnetic Tape Reading) Next, step 204 shown in FIG. 13(A) will be explained in detail according to FIG. 19.

At step 800, the magnetic tape 18 is fed leftward in FIG. 8 at a low speed (reading speed). In step 802, the timer T is cleared to 0. Then, the process proceeds to step 804.
It is determined whether the light emitted from the light emitting element 55 is received by the light receiving element 56. If there is leader tape 19 between light emitting element 55 and light receiving element 56, light is received and T is incremented in step 808. T in step 810
If ≦T0 or less, the processes of steps 804 to 810 are repeated.

Therefore, if the transparent part is fed a certain distance, T=T in step 81O, and it is determined that the tape is the leader tape 19, and the process proceeds to step 812.

If the light is blocked in step 804, the magnetic tape 1
8 or the blip mark 21 is detected, and in step 806, the tape 10 is fed at high speed to the right in FIG.

If the light emitted from the light emitting element 55 is blocked on the magnetic tape 1st in step 812, then in step 814 the erasing head 58
When the end mark data is read, the magnetic tape 18 is fed at high speed in the same direction in step 816. In step 818, the electrophotographic film 1 is inserted between the light emitting element 55 and the light receiving element 56.
6, and in step 820 it is determined whether or not the image is unfixed. The presence or absence of unfixed frames is written on the magnetic tape 18 in step 924, which will be described later, and written in the RAM 74 in step 814.
The determination is made based on whether or not the address shown in FIG. 10(B) is stored among the data read in.

If there is no unfixed frame, N0 blip marks 21 are counted in step 822, the process proceeds to step 824, and the high-speed feeding started in step 816 is stopped. The first (NO-1) piece is an unused piece, and the N0th piece has an absolute address l.

If there is an unfixed frame, the process shown in FIG. 8(C) is performed in step 826. After the process in step 824 or step 826 is completed, the process returns to the main routine.

In this way, the leader tape 19 is attached to one end of the magnetic tape 18.
Since this is connected, the reading start position can be determined without having to attach aluminum foil to the tape and detect it.

(Magnetic Tape Writing) Next, step 294 shown in FIG. 13(C) will be explained in detail according to FIG. 20.

At step 900, the tape 10 begins to be fed rightward in FIG. 8 at high speed. If the electrophotographic film 16 is located between the light emitting element 55 and the light receiving element 56 and is blocked by the blip mark 21, the process proceeds to steps 902 and 904. Go ahead and clear timer T.

The process then proceeds to steps 906 and 908, where T is incremented. In step 910, T≠Tt, and steps 906 to 910 are repeated. Since the width of the blip mark 21 is short, the light is received by the light-receiving element 56 in step 906, and the light is received in step 906 until the next blip mark 21 comes.
Loop 2.

When the tape 10 is fed and the magnetic tape 18 is located between the light emitting element 55 and the light receiving element 56, steps 906 to 91 are performed.
0 is repeated T1 times and the process proceeds to step 912. Next, in step 912, the process waits for the arrival of the leader tape 19, and proceeds to step 914, where it begins to feed the tape 10 to the left in FIG. 8 at low speed.

Next, the process advances to step 916, waits for the magnetic tape 18 to arrive again, and in step 918, the timer T is cleared.
Next, in steps 920 and 922, the count is counted until T becomes T, and the frame information is written to the magnetic tape 18 in step 924. This piece information also includes the addresses of unfixed pieces.

When writing is completed, the process advances to step 926, where tape 1 is
0 to the right in Figure 8 at high speed. Then step 9
Proceed to Step 28, wait for the leader tape 19 to come between the light emitting element 55 and the light receiving element 56, and clear the timer T with the original in Step 9.0 Next, in Steps 932 and 934, count until T reaches T3, and keep it constant. Wait until the leader tape 19 reaches the middle position after a period of time has elapsed, and step 936
At step 926, the rewinding started is stopped. Then, the process returns to the main routine.

In this way, the leader tape 19 is attached to one end of the magnetic tape 18.
Since this is connected, it is possible to determine the writing start position without having to attach aluminum foil to the tape and detect it.

In the above embodiments, the image information processing device to which the present invention is applied was explained as a microfilm camera processor league printer, but it may also be a device that projects image information onto a screen or a device that displays it on a CRT. Furthermore, the present invention can be applied to single-function devices or multi-function devices that project, display, search, and record image information, such as devices that record image information onto recording media such as films and disks.

In addition, films that form image information or on which image information is formed are described as electrophotographic films, but conventional silver halide films, thermoplastic films, photomigration type heat development films, and other types of heat development type silver halide films are also used. etc. are also used. Further, the magnetic tape connected to the leading edge of the electrophotographic film can be replaced with another storage medium such as a semiconductor memory.

(Effects of the Invention) In the image information recording medium according to the present invention, a transparent leader tape is connected to one end of a magnetic tape for recording image information, and a long film for recording an image is connected to the other end of the magnetic tape. Therefore, the start or end of the magnetic tape can be detected by detecting the change from the transparent part (leader tape or long film) to the opaque part (<M1 tape).
Furthermore, since the magnetic tape is wound on the reel after the leader tape is wound on the reel, there is no step difference in the wound magnetic tape, and the magnetic tape does not deteriorate, which is an excellent effect.
