The portion of the microfilm 102 that is stretched between the reels 104 is pulled out from the magazine 100 and wound around the photographing roller 202 of the magazine loading unit 200. The winding position of the photographing roller 202 is the exposure position.

On the other hand, a document detection sensor 46 is provided near the document insertion port 12A to detect the presence / absence of the document 16 inserted from the document insertion port 12B. A photometric sensor 48 is provided on the downstream side of the document detecting sensor 46 at a predetermined interval, and the recording surface of the document 16 is measured a predetermined time after the leading edge of the document 16 is detected by the document detecting sensor 46. It is supposed to do.

The drum 300 is provided at the center of the photographing device 10.
Is provided, and is rotated in the clockwise direction in FIG. 1 by the driving force of the driving means (not shown).

The inside of the drum 300 is hollow, and a plurality of small circular holes 302 (see FIG. 3) are provided on the peripheral surface.
Here, a negative pressure is applied to a part of the inner side of the drum 300, so that the conveyed document 16 can be attracted to be wound around the drum 300. Details of the internal structure of the drum 300 will be described later.

The original 16 is wound around the drum 300 for about half a turn, is turned by approximately 180 °, is peeled off from the drum 300, and is discharged to the stacker 50 disposed below the operating portion 14. It is like this. A lamp 58 is arranged corresponding to a region around the original 16 on the drum 300, and light emitted from the lamp 58 is applied to the original 16 on the drum 300. Here, the predetermined position which is wound around the drum 300 is the exposure position, and the optical system 400 corresponds to it.

The lamp 58 is lit with its illuminance adjusted based on the value detected by the photometric sensor 48. In addition, in the vicinity of the lamp 58, the illuminance sensor 52
Is attached to detect the illuminance of the lamp 58.

As a result, the reflected image of the original reaching the exposure position is taken by the optical system 400 to the photographing roller 202.

It becomes a reduced size.

(Structure for controlling the light quantity of the lamp 58) As shown in FIG. 4, the operation panel 28, the photographing start key 2
The document detection sensor 46, the photometric sensor 48, the illuminance sensor 52, and the lamp 58 are connected to the photometric control device 54.

Original document 1 conveyed by feeder unit 20
A plurality of document detection sensors 46 for detecting 6 are arranged along the direction (width direction) orthogonal to the insertion direction of the document 16 (five in this embodiment). Since the document 16 is fed with the left end in the insertion direction as a reference, the width of the document 16 can be recognized to some extent by the number of documents 16 detected by the plurality of document detection sensors 46. As the document detection sensor 46, a transmissive photoelectric sensor in which a light projecting section and a light receiving section are arranged with the conveyance path of the document 16 applied in between in the present embodiment, as well as, for example, the document 16 when the document 16 passes therethrough. A reflection type photoelectric sensor that receives the light reflected by 16, a limit switch that determines the presence or absence of the document 16 by a mechanical operation, and the like are applicable.

In the photometric control device 54, the illuminance sensor 52 controls the lamp 58 to a predetermined illuminance until the document detection sensor 46 detects the leading edge of the document 16.
That is, the illuminance setting knob 56 is arranged on the operation panel 28, and the illuminance according to the type of the original 16 can be selected by operating the illuminance setting knob 56. With the illuminance selected by the illuminance setting knob 56 as a reference, the photometric control device 54 feedback controls the illuminance of the lamp 58 (first mode).

The type of the original 16 is, for example, blank paper,
There are blueprints, tracing papers, catalogs, etc., and they correspond to the symbols attached around the illuminance setting knob in advance.

Although the optimum illuminance at the time of exposure is different for each original 16, the standard illuminance can be predicted. Therefore, this standard illuminance (or 9 of that illuminance
By controlling the illuminance of the lamp 58 in advance to about 0%), it is possible to quickly control the lamp illuminance at the start of shooting.

When the leading edge of the original 16 is detected by the original detection sensor 46, the photometric control device 54 is configured to measure the image surface of the original 16 by the photometric sensor 48 after a predetermined time. The photometric timing by this photometric sensor 48 is
The distance between the document detection sensor 46 and the photometric sensor 48, the document 1
6 and the original 1
The length is also changed according to the length of 6 in the conveyance direction.

That is, since the photometric area of the photometric sensor 48 corresponds to a part of the original 16 in a spot manner, the original 16
Depending on the size of, the photometric area may not be entirely on the image surface of the original 16. For this reason, in this embodiment, two types of photometric timing (short span and long span) after detecting the leading edge of the original 16 are set, and the original 1
6 is selected according to the size (see FIG. 5).

First, as shown in FIG.
When the length of 6 in the conveyance direction is short, the time from the start of photometry to the end of photometry is short, so the photometric value at the position immediately after the rising of the shortest document is applied. On the other hand, as shown in FIG. 5B, when the length of the document 16 in the transport direction is long, there is a region where the photometric value is stable for a predetermined time after the rising,
The photometric value after a lapse of a predetermined time after rising is applied. As a result, a more accurate photometric value can be obtained for a particularly long original 16 as compared with the case where the photometric time is set to one location (one time) regardless of the length of the original 16.

The photometric value at the photometric time is held as it is, and the photometric control device 54 determines the illuminance of the lamp 58 based on the photometric value, and further performs a predetermined correction according to the width dimension of the document 16. (See FIG. 6), the lamp 58 is turned on with a voltage according to the corrected illuminance (second
Mode).

That is, depending on the width dimension of the original 16, the photometric area may protrude in the width direction. Therefore, by correcting the photometric area of the peripheral surface of the drum 300, the optimum value can be obtained. it can.

During the second mode, the original 16 passes through the exposure position of the drum 300, and the photographing work is performed under a constant illuminance.

Next, when the rear edge of the original 16 is detected by the original detection sensor 46, the photometric control device 54 turns the lamp on after a predetermined time (time until the rear edge of the original 16 passes the exposure position). 58 is returned to the standard illuminance. In this case, if the second mode is immediately returned to the first mode, the feedback control in the first mode is immediately started, so that the return to the standard illuminance is delayed.

Therefore, in the present embodiment, the lamp illuminance at the time of switching from the first mode to the second mode is stored, and this lamp is lit after a lapse of a predetermined time after the trailing edge of the original 16 is detected. The voltage is set according to the illuminance (third mode). Thereby, the illuminance of the lamp 58 can be quickly brought to a value close to the standard illuminance.

The third mode is controlled for a predetermined short time, and when this time elapses, it returns to the feedback control based on the detection value from the illuminance sensor 48 (fourth mode = first mode).

By the way, as shown in FIG.
Then, a hole 16A for a tractor feeder is provided at the leading end in the conveying direction.
There are those provided with. When the position of the hole 16A and the detection position of the document detecting sensor 46 (see the reading locus shown by the one-dot chain line in FIG. 7) coincide with each other, one document 16
Is counted as two images, and the shooting timing may be incorrect (see signal A in FIG. 8). Therefore, the photometric control device 5
In FIG. 4, the signal B which is turned on for a predetermined time is generated by the fall of the detection signal A of the document detection sensor 46, and the signal C obtained by ORing the signals A and B is applied as the document detection signal. is doing. As a result, one original can be recognized as one regardless of the original 16 with and without holes. In this case, the detection of the trailing edge is slightly delayed, so it is necessary to consider it accordingly.

The other end of each of the connecting arms 148 is pivotally supported by a common shaft 150.

The shaft 150 is attached to a slide opening / closing base 152 arranged on the base portion 108 of the magazine 100. The slide opening / closing base 152 is housed between mutually parallel ribs 108F formed along the vertical direction of the base portion 108 of the magazine 100 (direction orthogonal to the linear side wall 110).
And is slidable in the vertical direction.
Therefore, when the slide opening / closing base 152 is slid, the shaft 150 is moved in the direction perpendicular to the shaft. When the slide opening / closing base 152 is separated from the shutter window 110A, the connecting arms 148 have a narrower included angle, so that the slide plates 140 are brought into close contact with each other, and the shutter window 11 is closed.
0A can be closed. On the other hand, when the slide opening / closing base 152 approaches the shutter window 110A, the connecting arms 148 widen the included angle, so that the slide plates 140 can be separated from each other and the shutter window 110A can be opened.

On the outer surface of the slide plate 140, the protrusion 1
40C is formed. The projecting portion 140C is moved together with the slide plate 140 after being loaded in the magazine loading portion 200, and can be engaged with the engaging means on the magazine loading portion 200 side when the shutter window 110A is fully opened. As a result, the magazine 100 is held in the magazine loading section 200.

A torsion coil spring 154 is attached to the common shaft 150, and both ends of the torsion coil spring 154 are locked to the connecting arms 148. The biasing force of the torsion coil spring 154 causes the slide opening / closing base 152 to
It is biased in a direction away from the shutter window 110A.

Corresponding to the slide opening / closing base 152, on the back side of the base portion 108 (outside the magazine 100),
A slide operation unit 156 is provided. Further, in the base portion 108 where the slide opening / closing base 156 is arranged,
The long hole 108G is formed, and the slide operation unit 1 is provided.
56 and the slide opening / closing base 152 are connected by a screw 158. Since the screw 158 penetrates the elongated hole 108G, it does not interfere with the base portion 108 when the slide opening / closing base 152 slides.

Therefore, by operating the slide operating portion 156, the slide plate 140 is moved through the slide opening / closing base 152, the connecting arm 148 and the arm portion 140A.
Can be opened and closed.

The slide operating portion 156 has a circular hole 156A.
Is provided, and when the magazine 100 is loaded at a predetermined position of the magazine loading unit 200, the pin 206 (see FIG. 11) on the magazine loading unit 200 side is inserted into the circular hole 156A. By moving the pin 206, the slide operation unit 156 is operated.

Here, the pin 206 on the magazine loading section 200 side inserted into the circular hole 156A and the push rod 13
The relative position with respect to the pin 204 on the magazine loading section 200 side inserted into the circular hole 108E through which 8C is exposed is determined, and even if an attempt is made to load the magazine 100 at a predetermined position,
When the position of the slide operation portion 156 is displaced (the shutter window 110A is opened), the loading operation cannot be performed. This allows the magazine 100
The condition and the reliability of loading are ensured.

A crank-shaped guide bracket 160 is placed on the slide opening / closing base 152, and is fastened together with screws 158 connecting the slide opening / closing base 152 and the slide operating portion 156. The guide bracket 160 is separated from the slide opening / closing base 152, and one end of a shaft 150 that pivotally supports the connecting arm 148 is engaged with the parallel portion.

The guide bracket 160 includes a lid 11
It is connected to the slide operation unit 156 provided on the second side. The slide operating portion 156 on the lid 112 side has a function similar to that of the slide operating portion 156 on the base 108 side, and is applied during the front-back reversal loading shown in FIG. See below).

A roller 164 made of synthetic resin is rotatably attached to the tip of the guide bracket 160 (on the side close to the shutter window 110A) via a shaft 162. The microfilm 102, which is stretched between the reels 104, is wound around the roller 164.

When the slide operation portion 156 is operated to open the shutter window 110A, the guide bracket 160 is moved in the direction of the shutter window 110A along with the movement of the slide plate 140 (movement in the opening direction). The shutter window 110A is projected to the outside. In this case, the length of the guide bracket 160 is determined so that there is no interference between the movement of the slide plate 140 and the guide bracket 160.

By this operation, the microfilm 10
2 is pulled out from the shutter window 110A, but since the reel 104 can freely rotate in the microfilm pulling direction, the microfilm 102 can be easily pulled out in a loop shape.

The drawn microfilm 102 is
The image pickup roller 202 on the magazine loading section 200 side is wound around by the operator's work.

(Magazine Loading Unit 200) FIG. 11 shows the magazine loading unit 200.

The magazine loading section 200 is composed of a photographing section 208 provided in the upper portion of the photographing apparatus 10 so as to project in a substantially mountain shape, and a holding section 210 for holding the magazine 100, and a casing for covering the photographing section 208. Slope portion 20 of 212
0A and 0B are the mounting portions of the magazine 100. The slopes 200A and 200B have an inclination angle of 45 °,
The structure is such that the magazine 100 is loaded in a state of being tilted at 45 °.

The holding section 210 has a guide base 214 mounted along the standing wall on the back side of the photographing section 208. The guide base 214 is the base portion 1 of the magazine 100.
It is facing 08. The guide base 214 has a rotation transmission plate 1 connected to the reels 104 in the magazine 100.
A drive plate 216 corresponding to 22 is provided.

The drive plate 216 is circular and has a pair of protrusions 216A formed on the periphery thereof. This protrusion 21
6A has a role of entering the notch 122A of the rotation transmission plate 122 and connecting the drive plate 216 and the rotation transmission plate 122.

As shown in FIG. 12, the drive plate 216 has its rotary shaft 216B penetrating to the back side of the guide base 214, and one rotary shaft 216B (the rotary shaft corresponding to the reel 104 on the winding side). A gear 218 is attached to the.

Corresponding to the gear 218, a roller 222 around which a timing belt 220 driven by the driving force of the driving means is wound is provided. This roller 222
Is formed with a flange 222A, and a tooth portion 222B meshing with the gear 218 is formed on the outer periphery of one of the flanges. Therefore, the drive force of the timing belt 220 can rotate the drive plate 216 corresponding to the reel 104 on the winding side via the gear 218 (drive side).

Further, on the other rotary shaft 216B (the rotary shaft corresponding to the reel 104 on the supply side), the rotary slit plate 22 forming a part of the rotary encoder at the protruding tip thereof.
4 is attached. The rotary slit plate 224 is provided with a plurality of slit holes evenly along the peripheral edge.

Corresponding to the rotary slit plate 224, a sensor 226 which constitutes a rotary encoder together with the rotary slit plate 224 is provided on a part of the outer circumference. The sensor 226 is a photoelectric sensor having a light-transmitting side and a light-receiving side which are bifurcated, and a part of the rotary slit plate 224 (a portion provided with a slit hole) passes between the bifurcated portions. ing. Accordingly, the sensor 226 can recognize the rotation speed of the rotary slit plate 224 from the detection signal (pulse count) of the sensor 226.

As shown in FIGS. 11 and 13, a microfilm take-out mechanism section 228 is arranged on the back side of the guide base 214 and between the rotary shafts 216B.

This microfilm take-out mechanism section 228
Has a bracket 230 attached as its base. The bracket 230 is a leg portion 230A in which upper and lower ends in the vertical direction with respect to the slope portions 200A and 200B are bent at a right angle in parallel with each other, and a circular hole 230B is coaxially provided. The shaft 232 is inserted through the circular hole 230B.

A long hole 234 is formed on the mounting surface of the bracket 230 to the guide base 214. Shaft 2
A pin 206 accommodated in the circular hole 156A of the slide operation portion 156 is attached to the axial center of 32 and penetrates the elongated hole 234. Further, a snap ring 238 is attached near the pin 206.
A compression coil spring 240 is attached between the retaining ring 238 and the leg portion 230A. This compression coil spring 2
Due to the urging force of 40, the pin 206 causes the upper end of the elongated hole 234 (the upper side along the vertical direction with respect to the slopes 200A and 200B).
Has been moved to the position where it abuts against. Pin 2 in this state
The position of 06 is the shutter window 110 of the magazine 100.
The position of the slide operating portion 156 when A is closed, and the circular hole 156 provided in the slide operating portion 156.
It becomes possible to insert into A.

A knob 242 is attached to one end of the shaft 232, and the slide operating portion 156 is opened in the opening direction of the shutter window 110A by gripping the knob 242 and pushing it down against the urging force of the compression coil spring 240. Can be moved to.

A lock pin 244 is attached to the outside of the leg portion 230A of the shaft 232. The lock pin 244 corresponds to a lock member 248 rotatably attached to the bracket 230 via a shaft 246. A torsion coil spring 250 is attached to the shaft 246, one end of which is locked to a part of the lock member 248 and the other end of which is locked to the bracket 230. The lock member 248 is formed with an inclined surface portion 248A, which is normally arranged on the movement locus of the lock pin 244 (when the shaft 232 moves in the axial direction) by the biasing force of the compression coil spring 240.

Here, when the lock pin 244 comes into contact with the slope 248A as the shaft 232 is pushed down,
The lock pin 244 causes the lock member 248 to rotate against the urging force of the torsion coil spring 250, and the slope 248.
It returns when it passes A. By this return, the return of the lock pin 244 (movement of the shaft 232 due to the biasing force of the compression coil spring 240) is blocked, and the shutter window 110A can be held in the open state by the slide operation portion 156.

As shown in FIG. 11, the photographing units 208 are each in the shape of a triangular box, and are individually provided for the two magazines 100 to be loaded. The configuration of one image capturing unit 208 is shown below.

The photographing section 208 is provided with a lid and is normally shielded from light. Since the microfilm 102 applied to this embodiment has a lower sensitivity than a silver salt film used for shooting with a general camera,
There is no problem with some leakage light. For this reason,
Preparation for winding the microfilm 102 around the photographing roller 202 can be performed with the lid 252 open.

When the magazine 100 is loaded on the slopes 200A and 200B and the shaft 232 is pushed down, the microfilm 102 is pulled out in a loop shape into the photographing section 208.
The reference numeral 2 passes through the inside of a pair of synthetic resin guide rollers 254 and 256 and is wound around the photographing roller 202.

Here, the entrance side guide roller 254 is formed with a flange portion 254A, which guides the width direction of the microfilm 102, and the photographing roller 20 in an appropriate state.
It is designed to be wrapped around 2.

The photographing roller 202 has a peripheral surface made of rubber and is rotated at a predetermined rotation speed by the driving force of the driving means. Here, the reel 104 on the take-up side includes the photographing roller 202.
Since the microfilm 102 is rotated a little faster than the rotation of No. 1 and is rotated with a low torque, the microfilm 102 is conveyed without sagging and the relative position between the photographing roller 202 and the microfilm 102 is not displaced.

The microfilm 102 wound around the photographing roller 202 is irradiated with the light guided by the optical system 400. The light exposes the microfilm 102.

The light guided by the optical system 400 is the reflected light of the image of the original 16 wound around the drum 300, and the rotation of the drum 300 and the rotation of the photographing roller 202 are synchronized with the reduction ratio. , Slit exposure will be performed.

(Drum 300) As shown in FIG.
The drum 300 is provided with a plurality of circular holes 302 that connect the outer circumference and the inner space.

Inside the drum 300, a chamber 308 is arranged. The chamber 308 has a small diameter cylinder 309 with one end closed, and five partition plates 311A extending in the radial direction along the longitudinal direction of the small diameter cylinder 309.
311E and two partition plates 313A and 313B fixed to the end faces of the partition plates 311A to 311E in the axial direction to form chambers 308A to 308D.
The partition plate 313A located on the closed end side of the small diameter cylinder 309
Partially cut out in a fan shape, and this cutout portion faces the chamber 308B serving as a suction portion. Also, the small diameter cylinder 309
Has a plurality of small holes opening toward the room 308D that serves as the peeling portion.

The end surface of the drum 300 is open, and the fan 306 is arranged correspondingly. When the fan 306 is driven, the air in the suction section (room 308B) in the inner space of the drum 300 is sucked out, so that the room 30
The inside of 8B is made negative pressure negative pressure. Therefore, this room 308
Air is sucked from the circular hole 302 of the drum 300 corresponding to B, and the document 16 fed from the tangential direction of the drum 300 is sucked by the drum 300.

On the other hand, the fan 309 is provided in the small diameter cylinder 309.
Air is supplied to the room 308D. As a result, the air is sent into the room 308D, and the air is blown out from the circular hole 302 of the drum 300 in the region corresponding to the room 308D.

Therefore, the original 16 is easily separated from the drum 300 by the blown air. The chambers 308A and 308C are located on the entrance side of the document 16 and at the boundary between suction and separation.

As a result, the original 16 can be surely adsorbed over about half the circumference of the drum 300 and can be reliably peeled off.

A thin plate-shaped porous filter 310 is wound around the peripheral surface of the drum 300. The porous filter 310 has a function of spreading the suction area over the entire area of the drum 300 so that the suction area is biased near the circular hole 302 and no suction mark remains when the original 16 is sucked.

The porous filter 310 will fall off only by being wound around the drum 300, so the porous filter 31
0 is covered with a thin woven fabric cover 312 which has elasticity and is seamless and easy to exchange. As such a fabric cover 312, a stretchable mesh such as a nylon mesh is preferable.

The woven cloth cover 312 prevents the porous filter 310 from falling off, and the woven cloth cover 312 itself has a filter effect, so that the suction effect of paper dust can be improved.

The central portion (27 ° with respect to the horizontal direction) of the area from the time when the original 16 is sucked up to the time when the original 16 is peeled off, the optical system 400
Is set to the exposure position for guiding the image of the original 16 toward the photographing roller 202 (see FIG. 3), and the glass plate 314 is used.
Is provided. The glass plate 314 has a role of reliably bringing the original 16 into close contact with the drum 300 at the exposure position, and particularly prevents the rear end of the original 16 from jumping up.

Further, the upstream side of the exposure position of the drum 300, that is, the upper part, is covered with a low-friction sheet 316. The sheet 316 narrows the suction area from the circular hole 302, and improves the suction effect of the small-sized document 16. The necessity of low friction is to prevent static electricity from being generated because the drum 300 slides as the drum 300 rotates. For this reason, it is preferable to have conductivity, and specifically applicable are metal foil such as aluminum foil and phosphor bronze foil (preferably having a thickness of about 0.02 mm). Further, even the surface-treated special paper can have an effect of increasing the suction force (for example, Toray's Soldion tape "trade name").

The tip of the sheet 316 is pressed by the glass plate 314 to prevent it from fluttering.

(Original Image Photographing Optical System 400) FIG. 3 shows an optical system 400 for guiding the light radiated to the image of the document 16 wound around the drum 300 to the microfilm 102 wound around the photographing roller. It is shown. A bracket 402 extends from the lamp stay 60 that holds the lamp 58 toward the optical path. A mask 404 is attached to the bracket 402.

The mask 404 is provided with a slit hole 404 having a width of about 14 mm and corresponding to the axial length of the drum 300, and the light is transmitted through the slit hole 40 of the mask 404.
It is designed to pass 4A.

The drum 300 corresponding to this mask 404
The upper exposure position is located at an elevation angle of 27 ° with respect to the lateral side, and its optical axis is perpendicular to the tangent line of the exposure position of the drum 300.

The light passing through the mask 404 is reflected by the reflecting mirrors 406 and 40 attached to the bracket 406, respectively.
It is reflected by 8 and guided toward the photographing roller 202 located on the upper surface of the photographing device 10. A lens 412A held by a cylindrical body 412 is provided on the upstream side of the photographing roller 202, collects the light guided by the reflection mirrors 406 and 408, and winds the microfilm 102 around the photographing roller 202.
It is designed to form an image on the top. Also, this lens 41
A shutter 414 is provided on the upstream side of 2A, and is opened after a lapse of a predetermined time after the leading edge of the original 16 is detected by the original detection sensor 46 after the start of photographing, and a predetermined time has passed after the rear edge of the original 16 is detected. It will be closed later.

The photographic roller 202 has a pitch dimension of 34 mm between the respective axis centers, and the optical axis having an elevation angle of 27 ° reaches the center of the pair of photographic rollers 202. The slit width of the light passing through the slit hole 404A is set so that the two photographing rollers 202 are simultaneously irradiated.

Therefore, the same image can be photographed on the microfilm 102 wound around the photographing roller 202 almost at the same time.

(Blip mark and number photographing optical system 500) As shown in FIG. 15, the blip mark and number photographing optical system 500 (hereinafter referred to as the sub optical system 500) are arranged side by side with the image photographing optical system 400. Is provided. This sub-optical system 500 is, as shown in FIG.
Image frame 102A photographed on the microfilm 102
The blip mark 102B for determining the position of this image frame corresponding to the above and a specific number (film number and frame number) 102C for identifying this image frame 102A are printed on the microfilm 102.

As shown in FIG. 15, this sub optical system 50
A halogen lamp 502 is disposed in the light source unit of 0, and the light emitted from the halogen lamp 502 passes through the condenser lens 504 and the diffusion plate 506 and is passed through the liquid crystal shutter 5
It reaches to 08.

The liquid crystal shutter 50 as shown in FIG.
Reference numeral 8 is an elongated shape, and a 7-dot liquid crystal window and a rod-shaped liquid crystal window are provided in one row along the longitudinal direction.

The light passing through the liquid crystal shutter 508 passes through each lens 412A of the optical system 400 and is focused on the macro flume 102.

The operation timing of the liquid crystal shutter 508 is determined by the rotation speed of the photographing roller 202 (microfilm 1
It is synchronized with the linear velocity of 02), and the liquid crystal window is opened and closed based on the data for each line at regular intervals. As a result, the specific number 102C is printed in a dot pattern (see FIG. 17), and the blip mark 102B is printed as a rectangular mark by continuously opening for a predetermined time.

Here, depending on the size of the document 16, the photographing of the document image may be completed before the time (for 10 digits) for burning the frame number 102C by the sub optical system 500 is reached (FIG. 16). Third image frame 10 from the left
2A). In such a case, if the shutter 414 is closed due to the end of the document, the frame number may be imprinted only halfway. Therefore, in the present embodiment, when the shutter 414 is closed, if the burning of the frame number is not finished, the shutter 414 is closed after waiting for the burning of the frame number.

The operation of this embodiment will be described below. First, a description will be given of the work from the receipt of the manuscript (slip) 16 to the photographing in the financial institution.

First, the envelopes containing the originals 16 sent to the head office of a financial institution are classified by company and customer, and the envelopes are opened and wrinkles and the like of the folded originals 16 are straightened.

Next, the number of originals is checked and the list table is filled in. Then, an attachment is prepared, and a sticker 36 with a bar code 34 showing the order number is attached.

Next, information including this bar code number (registration date, division, store number, subject, account number, depositor name, trustee code, self-assignment code, accommodation company code, contractor number)
Is entered and the entered information is stored in the host computer 40 via the storage medium 38. After completing the entry, after checking the entered list,
The manuscript 16 is categorized by branch office and the manuscript 16 is sent to each branch office.

The sent document 16 is returned to the head office after being inquired about the seal at each branch. Further, the regular parts returned from the branch (including those that have been corrected and re-submitted after being returned) are placed one by one on the document table 18 of the photographing apparatus 10 in the order in which they are bundled.

When placed on the document table 18, the barcode 34 is read by the barcode reading section 32, information is retrieved from the computer 42 based on the number corresponding to the barcode 34, and the information is displayed on the display 44. indicate.

The operator collates the displayed contents with the contents actually written on the original 16, and if they match, operates the photographing start key 26. By this operation,
The feeder unit 20 operates to load the document 16 with the document insertion port 12B.
It is conveyed in the direction and the image is taken. The shooting procedure and the like will be described later.

When the photographing is completed, the microfilm 10
The shooting frame number of 2 is added to the above information and stored again in the storage medium 38 of the computer 42.

Thus, the bar code 34 attached to the actual original 16 is read, various information is retrieved from the computer 42 based on the read bar code 34 information, and the displayed information is displayed. Since the information of the original document placed on the document table 18 is compared with the original document data, even if the order of data entry is different or missing, the document is placed on the document table 18 first. It is possible to take pictures in the order of placement.

That is, conventionally, information is read out from the computer 42 in the order of data lintry and displayed, and this display is collated with the information of the document 16 to be photographed. Therefore, when data entry is made as described above. If the order is different from the above, collation is not established and it takes time and effort to search the manuscript. For this reason, there has been a situation in which the photographing work has to be temporarily interrupted. However, in the present embodiment, since there is no such temporary interruption of the photographing work, the photographing work can be efficiently performed.

If the number of continuous shots is set in advance (for example, 100 times) and the missing serial number read by the bar code 34 is displayed each time this number of times ends, it is easy to read the unshot originals. Can be confirmed.

Next, a procedure for loading the magazine 100 into the photographing device 10 will be described. In the image capturing apparatus 10 of this embodiment,
Two magazines 100 can be loaded at the same time,
Since the loading procedure is the same, one magazine 100
Only the loading of will be described.

In the new magazine 100, the raw microfilm 102 is wound around the supply side reel 104, and the outermost microfilm 102 is inserted into the base shaft of the winding side reel 104. The lid 112 in this state
Is placed on the upper end of the side wall 110 of the magazine body 106, and the lock operating portion 118 is rotated to engage the lock member 116 and the upper end portion 114B of the bracket 114, so that the lid body 112 can be fixed. . like this,
In the state of the magazine alone, in the supply side reel 104, the tooth portion 120A of the gear 120 is the claw portion 128B of the locking claw 128.
Since the micro film 102 can be rotated in the pull-out direction, the rotation in the winding direction is prevented. On the other hand, the reel 104 on the winding side is rotatable in the winding direction of the microfilm 102, but is prevented from rotating in the drawing direction.

In this state, the magazine 100 is placed on the slope portion 200A (200B) of the magazine loading section 200 and abutted against the holding section 210. Here, the holding portion 210 has two pins 204 and 206 protruding, and correspondingly, the circular holes 108 are formed in the magazine 100.
E and 156A are provided. If the slide operation portion 156 of the magazine 100 is in the regular position (the shutter window 110A is in the closed state), these intervals are the same. The back side (back side) of the portion 108 can be brought into close contact with the holding portion 210. As a result, the notch 122A of the rotation transmission plate 122
Engages with the projection 216A of the drive plate 216, and the drive plate 2
The rotation of 16 can be transmitted to the rotation transmission plate 122.

When the magazine 100 is placed at a predetermined position, the knob 242 attached to the tip of the shaft 232 is gripped and pushed down in the direction of the slope 200A (200B). In this pressing operation, the pin 206 is housed in the circular hole 156A of the slide operating portion 156, so the slide operating portion 156 is pressed down.

In this state, the push rod 1 of the pressing member 138 is
38C is pushed, and the arm 132 is moved by the slope 138A.
Push down. As a result, the locking claw 128 has the circular hole 12
8A rotates about the biasing force of the torsion coil spring 130, and the claw portion 128B separates from the tooth portion 120A of the gear 120. Therefore, the reel 104 can be rotated in either the winding direction or the drawing direction of the microfilm 102.

By pushing down the slide operating portion 156, the slide opening / closing base 152 slides,
Expand the included angle of the connecting arm 148. Due to this expansion, the slide plates 140 slide in directions away from each other, and the shutter window 110A can be opened. Further, a protrusion 140C is formed on the slide plate 140, and is fitted with the sloped portion 200A (200B) when opened, so that the magazine 100 can be securely attached to the sloped portion 200A (200B).
B) Can be fixed on.

Simultaneously with the opening operation of the slide plate 140, the guide bracket 160 moves to allow the roller 164 to project from the shutter window 110A. By the way, the microfilm 102, which is wound between the reels 104, is wound around the roller 164.
According to the opening operation of 10A, it can be sent to the imaging unit 208 of the magazine loading unit 200.

When the shaft 232 is pushed in by a predetermined amount,
The lock pin 244 interferes with the lock member 248, and the state in which the lock pin 244 is pushed in against the biasing force of the compression coil spring 240 is maintained. Therefore, the shutter window 110A is kept open, and the microfilm 102 can freely move in and out.

In this state, the operator passes the microfilm 102 between the guide rollers 254 and 256 and winds it around the photographing roller 202. With this, the preparation for photographing is completed, the photographing roller 202 is rotated, and the reel 104 is rotated.
The micro film 102 is sequentially unwound from one reel 104 to the other reel 104 by the rotation of, and is wound up. The rotation speed (linear speed) of the take-up reel 104 is slightly higher than the rotation speed (linear speed) of the photographing roller 202 and has a low torque, so that the microfilm 102 is wound without slack. Further, since the guide roller 254 on the entrance side is provided with the flange, it is guided in the width direction of the microfilm 102 and is reliably wound around the photographing roller 202 at a predetermined position.

The procedure until the conveyed original 16 is photographed on the microfilm 102 will be described below with reference to the flowcharts of FIGS. 18, 19 and 20.

First, the illuminance control routine for the lamp 58 will be described with reference to FIG. In step 600, the paper type set by the illuminance setting knob 56 is determined,
Next, the standard illuminance L _{1 of} the paper type determined in step 602
Read out.

In step 604, the actual lamp 58
Illuminance L₂Is detected by the illuminance sensor 52, and step 6
Standard illuminance L read in 06₁Lamp illumination detected as
Degree L ₂Compare with.

As a result of the comparison, when L ₁ > L ₂ is determined, the routine proceeds to step 608, the lamp power source is increased by a predetermined amount, and then the routine proceeds to step 612. When it is determined that L ₁ <L ₂ , the process proceeds to step 610, the lamp power source is reduced by a predetermined amount, and the process proceeds to step 612. Further, when it is determined in step 606 that L ₁ = L ₂ , the process directly proceeds to step 612.

At step 612, it is judged whether or not the leading edge of the original 16 is detected by the original detection sensor 46.
In the case of negative determination, the process returns to step 600, and steps 600 to 612 are repeated. By this feedback control, the illuminance of the lamp 58 is controlled to the set standard illuminance (first mode).

If it is determined in step 612 that the leading edge of the original 16 has been detected, the process proceeds to step 614, the lamp voltage at this time is stored, and the process proceeds to step 616. In step 616, it is determined whether or not the length of the document 16 is equal to or longer than a predetermined length, and in step 618, the time t until the photometry of the document 16 is determined according to the success or failure.

In step 620, it is determined whether or not the determined time t has elapsed, and if an affirmative determination is made, the process moves to step 622 and the photometric sensor 48 starts photometry. Since the time t is determined according to the length of the document 16, it is possible to obtain a stable photometric value particularly when the document is long.

When photometry is performed in step 622, the process proceeds to step 624, and the lamp voltage is set based on this photometric value. Next, in step 626, the set lamp voltage value is corrected based on the document width, and in step 628.
Then, the corrected voltage is applied to the lamp 58. That is, the lamp voltage is held based on the photometric value measured in step 622, and the photographing process is performed during this period (second mode).

Next, at step 630, it is judged that the trailing edge of the document 16 is detected by the document detection sensor 46,
When it is affirmed that the predetermined time has elapsed in step 632, the process proceeds to step 634, the voltage value stored in step 614 is read, and then the voltage read in step 636 is applied to the lamp 58. Next step 6
At 38, it is determined whether or not a predetermined time has elapsed, and if an affirmative determination is made, the process returns to step 600. (Fourth mode =
First mode). As a result, the control voltage before shifting to the second mode can be quickly changed, and thus the interval for returning to the standard illuminance for the next shooting can be shortened.

Next, the detection control by the document detection sensor 58 will be described with reference to the flowchart of FIG. In this embodiment, a high-level signal is output when the original detection sensor 58 detects the original 16, and a low-level signal is output when the original 16 is not detected.

First, in step 650, the trailing edge is detected from the output signal A of the document detection sensor 46 to the photometric control device 54. Next, at step 652, a signal B that outputs a pulse wave that is output for a predetermined time after the fall is detected is generated. The output time of the signal B may be set by the operator according to the situation of the document 16.

In the case of a normal original document 16, this signal B is only when the trailing edge of the original document 16 is detected.
In the case of No. 6, when the document detection sensor 58 passes through this hole position, a rectangular wave having a small pulse width is first generated, so that the signal B also detects the trailing edge of this rectangular wave and detects 2 in one document. The number of pulse waves will be generated.

At step 654, the signal A
And the signal B are ORed, and the generated signal C is applied as a document detection signal (step 656).

As a result, one original 16 can be recognized as one although the detection position is slightly displaced, and the photographing count and the like can be made reliable.
It should be noted that there is no problem if the detection position shift amount is taken into consideration in advance.

Next, the photographing procedure will be described with reference to FIG. When it is confirmed in step 700 that the shooting start key 26 is operated, the feeder unit 20 is driven in step 702, and then the rotation of the drum 300 is started in step 704.

At the next step 706, the fan 306 is driven to make the inside of the drum 300 (the space where the chamber 308 does not exist) a negative pressure, and at the next step 708, air is sent to the chamber 308.

As a result, from the document winding start position (near the upper end of FIG. 3) on the drum 300 to the peeling position (FIG. 3).
Since the air is sucked through the circular hole 302 up to the vicinity of the lower end), the conveyed document 16 can be sucked.
On the downstream side of the peeling position, conversely, the air from the chamber 308 blows out from the circular hole 302, so that the document 16 is reliably peeled from the drum 300.

Here, since the porous filter 310 is wound around the peripheral surface of the drum 300, the suction force concentrated around the circular hole 302 can be spread evenly over the entire drum 300, and the original 16 It is possible to prevent a suction mark from being left on the original 16 during the suction of. In the past, the porous filter 310 was adhered to and held by the peripheral surface of the drum 300 with an adhesive, but in the present embodiment, a nylon mesh is further provided on the upper layer of the porous filter 310. Since the tubular fabric cover 312 is covered and held, for example, when replacing the porous filter 310, the porous filter 310 can be easily removed by removing the fabric cover 312. The maintenance workability can be greatly improved. Further, the fabric cover 312 itself has a filter effect, and the suction effect of paper dust can be improved.

As described above, when the original 16 is horizontally conveyed from the tangential direction to the drum 300 covered with the porous filter 310 and the cloth cover 312, the original 16 is transferred to the drum 3.
It is adsorbed on 00 and wound. During the horizontal conveyance of the document 16, the surface of the document 16 is measured and the illuminance of the lamp 58 is adjusted, and the document 16 reaches the exposure position while being wound around the drum 300. This exposure position is a position with an elevation angle of 27 ° with respect to the side of the drum 300, and a glass plate 314 is arranged at this position.
With this glass plate 314, the original 16 is placed on the drum 300.
Slit exposure is performed in a state of being closely attached to the peripheral surface of the. In particular,
At the rear end of the document 16, the document 16 may be separated from the drum 300 due to splashing or the like to cause a change in the optical path length. However, in this embodiment, the document 16 is pressed by the glass plate 314. Therefore, it is possible to reliably prevent the original 16 from floating.

Further, there are various sizes of the original document 16, and for example, in the case of a small-sized original document, the original document 16 cannot be blocked in the axial direction of the drum 300 and the circular hole 302 cannot be blocked, and the suction effect can be obtained. It may decrease. Therefore, the low-friction sheet 316 is covered between the vicinity of the suction position of the original 16 and the exposure position to narrow the suction area from the circular hole 302 to improve the suction effect of the small-sized original 16. As a result, even the original 16 having a small width can be reliably sucked into the drum 300. Also, since this sheet 316 has low friction, the drum 3
It is possible to prevent the generation of static electricity even when it is slid along with the rotation of 00.

Further, the front end of the sheet 316 is pressed by the glass plate 314, and it is possible to prevent fluttering.

Here, in step 710, when the leading edge of the original 16 reaches the exposure position with the rotation of the drum 300 (a predetermined time after the leading edge of the original 16 is detected by the original detection sensor 46), step 712. Then, the shutter 414 is opened and the photographing roller 202 is synchronously rotated in step 714. Therefore, the image of the original 16 stably fed to the exposure position is slit-exposed by the optical system 400.

That is, the image of the original 16 is the mask 40.
The light passes through the slit hole 404 provided in No. 4, is reflected by the reflection mirrors 406 and 408, and is imaged on the microfilm 102 wound around the photographing roller 202 by the lens 412A. Therefore, the two photographing rollers 2
Each microfilm 10 wrapped around 02
In 2, the same image can be taken almost at the same time.

When the trailing edge of the document 16 is detected by the document detection sensor 46, the shutter 414 is normally closed after a lapse of a predetermined time and the photographing is completed. However, in this embodiment, at the same time as the photographing of this image. The sub-optical system 500 prints the blip mark 102B and the frame number 102C near the image frame 102A.

Blip mark 102B and frame number 10
In 2C, the shutter windows of the liquid crystal shutters 508 arranged in a row are used to rotate the photographing roller 202 (microfilm 10
The blip mark 102B becomes a continuous rectangular mark by opening and closing in accordance with (movement of 2), and the frame number can be imprinted in a dot pattern.

Here, when the document size (especially in the length direction) is small, the shutter 414 may be closed before all the frame numbers 102C are printed. Therefore, when the shutter 414 is closed, the photographing is completed (a predetermined time has elapsed after the trailing edge of the original 16 was detected) or the frame number 102C.
Whichever is later, is selected (steps 716, 718, 72).
0). In this case, the rotation of the photographing roller 202 is continued.

As a result, the frame number 102C can be surely printed without using a means for reducing it.

Next, in step 722, the next original 1
If 6 is on the document table 18, the shooting start key 26 may be immediately operated in step 722. Therefore, in step 724, it is determined whether the shooting start key 26 has been operated with the driving system being driven. If it is determined that the result is affirmative, the feeder unit is driven in step 726, and then the process proceeds to step 710.

If a negative decision is made in step 720, the drive system is stopped in step 728, and step 70
Move to 0.

When the document 16 reaches the peeling position of the drum 300, the document 16 is peeled from the drum 300 by the air blown from the circular hole 302, guided to the stacker 50, and discharged.

In this embodiment, as shown in FIG. 21A, since the pressing member 138 is provided only on the base portion 108 side, the side facing the holding portion 210 is limited to the base portion 108. As shown in FIG. 21B, the end portion of the arm operation base 136 on the lid 112 side is extended to form a slope portion 136B that is the same as the slope portion 136A, and the base portion 108 of the lid 112 is formed. By providing the circular hole 112B similar to the circular hole 108E and disposing the pressing member 139, the holding portion 2 of the magazine 100 can be mounted regardless of the front and back sides.
Can be faced to 10.

In this case, the rotation transmission plate 12 on the lid 112 side.
2 engages with the drive plate 216 to receive a driving force, and the slide operation portion 157 on the lid 112 side is slid to move the slide plate 140 and the guide bracket 160.
