Description

TECHNICAL FIELD The present invention relates to a micro camera for photographing a document as an image on a film. That is, the present invention relates to a micro camera for reducing originals of various sizes, such as A3 and A4, according to the sizes, and photographing a large amount of images on a film.

"Prior Art" Such a micro camera has conventionally been as follows.

That is, first, in the embodiment of Japanese Patent Laid-Open No. 59-83131, a technique of discriminating the size of a document, adjusting the size of the aperture of the photographing mechanism according to the result, and controlling the film feeding according to the size It is shown. According to this technique, when the size of the document is changed, there is an advantage that the shooting of the image can easily and easily cope with this.

In the past, there were various types of micro cameras,
No technique is shown for printing a size mark corresponding to the size of the original on the film.

"Problems to be Solved by the Invention" By the way, the following problems have been pointed out in such a conventional example.

That is, when a film photographed by such a micro camera is to be subsequently enlarged and copied by, for example, a reader printer, a printer, etc., the size of each image of this film is first discriminated and A3, A
It is necessary to select and feed copy paper such as 4th grade.

The size of the image is discriminated by the operator's visual observation or by using a large number of sensors as shown in JP-A-59-30550.
Therefore, such determination is troublesome, has many mistakes, has a complicated configuration, and is inefficient, which is a problem.

It is also conceivable to determine the size of each image and imprint the size mark on the film photographed by such a micro camera prior to subsequent enlargement copying, but the imprinting work is cumbersome and efficient. There was some indication that it was bad.

In the conventional example, the above problems have been pointed out.

In view of such circumstances, the present invention has been made to solve the problems of the above-mentioned conventional example, and can easily and easily imprint a size mark around an image,
The purpose of the present invention is to propose a micro camera in which the size mark facilitates the subsequent size determination of the image.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a photographing means for photographing a small-sized original and a large-sized original on a film at the same reduction ratio, and an image taken by the photographing means. And an imprinting mechanism for imprinting a size mark corresponding to the original size discriminated by the discriminating unit on the periphery of the image photographed by the photographing unit on the film. It is characterized by

"Operation" Since the micro camera according to the present invention comprises such means, it operates as follows.

That is, the size of the document is determined by the determining means, and the document is positioned at a fixed position.

Then, the original is photographed as a reduced image on the film, and a size mark corresponding to the size of the original is imprinted around the image by the imprinting mechanism based on the discrimination result of the discrimination means.

In this way, the size mark can be easily and easily imprinted around the image. The size mark also facilitates the easy determination of the size of the image in the subsequent enlargement copying or the like.

[Examples] The present invention will be described in detail below based on the examples shown in the drawings.

First, the configuration will be described in order of the overall configuration, an automatic feeding mechanism, a photographing mechanism, a size mark, an imprinting mechanism, a discriminating means, and the like.

The outline of the overall configuration is as follows.

FIG. 1 and FIG. 2 show one example thereof, FIG. 1 is a perspective view, and FIG. 2 is a front sectional view.

Reference numeral 1 denotes a substantially rectangular base, and a fixed column 2 is erected on one side of the base 1 along the longitudinal direction. A pair of arms 3 and 3 are horizontally provided at the base end of the fixed column 2, and light sources such as illumination lamps 4 and 4 are attached to the arms 3 and 3. A camera head 6 is fixedly mounted on the upper end of the fixed column 2 via a beam 5. A set tray 7 for the original C is attached to one end of the base 1, and a discharge tray 8 for the original C is attached to the other end of the base 1.

The outline of the overall configuration is as follows. Next, the automatic feeding mechanism will be described.

In the illustrated micro camera, FIG. 1 and FIG.
As shown in the figure, an automatic feeding mechanism 9 for the document C is incorporated. The automatic feeding mechanism 9 feeds the document C from the set tray 7 onto the base 1, feeds the base 1 and stops it appropriately, and feeds it to the discharge tray 8.

The automatic feeding mechanism 9 is rotationally driven by a driving source (not shown) and is fed out to the original C in the set tray 7 by pressure.
A pair of upper and lower separating rollers 11 and 11 for restricting only one original C to be sent to the next, and separating rollers 11 and 11 rotationally driven by a drive source (not shown).
A feed roller 12 that feeds one original C fed next through the feed roller 12, and an auxiliary roller 13 that faces the feed roller 12.
And the following conveyor belt 14. As the conveyor belt 14, for example, a suction belt is used, which has a large number of through holes on the surface of the belt main body, and a document C placed thereon is sucked by an attached air suction device (not shown). And then transport. The conveyor belt 14 is assembled to the base 1 so as to be driven by the drive rollers 15 and 15 which are rotationally driven by a drive source (not shown), and the feed roller 12
The original C sent by is sucked and conveyed on the base 1 from the set tray 7 side to the discharge tray 8 side, and can be stopped appropriately. Conveyor belt 14 at rest
Functions as a document table, and the light from the illumination lamps 4, 4 is in a positional relationship of irradiating the document C on the conveyance belt 14 in the stopped state. In the figure, 16 and 16 are guide rollers, and 17 is a separation claw for separating the document C from the conveyance belt 14.

Firstly, in the automatic feeding mechanism 9 of the illustrated example, the document C is conveyed by the conveyor belt 14 and is in a fixed position where the center lines are aligned regardless of the size, that is, the edges are not uniform and the stop positions are different. In this state, the so-called centering method is adopted in which the positioning is stopped on the base 1 (see the phantom line in FIG. 2). However, the present invention is not limited to this center alignment method, and it is of course possible to adopt a so-called one-side alignment method in which the document C is stopped and positioned on the base 1 by aligning the rear edges regardless of size. .

Secondly, the invention is not limited to the one in which the automatic feeding mechanism 9 is incorporated as in the illustrated example, and the original C is manually placed in a fixed position on the original table provided on the base 1. It may be positioned.

The automatic feeding mechanism 9 has such a structure.

Next, the photographing mechanism will be described.

In the photographing mechanism 18, a lens 19 is fitted in the bottom opening of the closed camera head 6 having a box shape, and a lens shutter (not shown) is disposed inside the camera head 6 so as to face the lens 19.
And an aperture 20 to be described later is formed. The light from the illumination lamps 4, 4 illuminates the document C on the conveyor belt 14 in the stopped state, and then the lenses 19,
Aperture 20 through the lens shutter in the released state
The exposure range is set by, and the lower surface of the film F is projected and exposed, and the image P (see FIG. 7) is photographed. The film F is sent out from the unexposed supply-side reel 21 in the camera head 6, and is guided to the exposed take-up side reel 22. The guide roller 23, the film feeding roller 24 and the film feeding roller 24 are driven to rotate. A predetermined amount is intermittently fed through a driven roller 25 that is located opposite to. The feed amount of the film F is calculated based on the size of the document C photographed last time and the size of the document C photographed this time.

The aperture 20 is arranged in the camera head 6 as shown in FIG. 3, for example. Ie this aperture
20 is a pair of rectangular notches 2 of the light shielding plates 26, 27 facing each other.
The 6 _1, 27 _1, its size variable in response to the size of the original C, is formed. The light-shielding plates 26, 27 are movable in opposite directions along the document C transport direction and the film F transport direction, and their cutouts 26 ₁ , 27 ₁ changes from the connected state to the superposed state, so that, for example, apertures 20 for A3 size and A4 size are formed, respectively.

Racks 28 and 29 are fixed to the side ends of the light shielding plates 26 and 27, respectively.The racks 28 and 29 mesh with a pinion 30, and a fan-shaped gear 31 is coaxially fixed to the pinion 30 to output gears. The input gear 32 meshes with the barrel fan gear 31, and the input gear 32
Is fixed to the motor shaft of the first motor M1 capable of rotating in the forward and reverse directions. Therefore, the light shielding plate 2 is rotated by the forward and reverse rotations of the first motor M1.
6,27 will move apart and move closer.

A detection plate 33 is bent and formed at a corner of the light shielding plate 27, and the detection plate 33 can be detected by the sensors S1 or S2 arranged in a row. Therefore, for example, when the original C is A4 size, the light shielding plates 26 and 27 are positioned close to each other, and the partially overlapped notches 26 ₁ and 27 ₁ form the aperture 20 for A4 size, and The detection plate 33 is positioned to be detected by the sensor S1. Light source 2 when document C is A3 size
6 and 27 are positioned apart from each other and are notches in a connected state
An aperture 20 for A3 size is formed by 26 ₁ and 27 ₁ , and the detection plate 33 is positioned so as to be detected by the sensor S2. In this way, the sensors S1 and S2 allow the light shielding plates 26 and 27
Position and the size of the aperture 20 are detected and determined.

In the illustrated example, a roll film is used as the film F and the photographing mechanism 18 of the film F is described, but the invention is not limited to this, and a fish film is used as the film F and the photographing of the film F is performed. Of course, application in a mechanism is also possible.

The photographing mechanism 18 has such a structure.

Next, the size mark will be described.

FIG. 7 shows an example of the size mark A.
Is printed around the image P on the film F, corresponds to the size of the original C, and has the distinguishability that can be detected by the detection means in the poster reader printer or the like. Size mark in the illustrated embodiment A comprises the identity of which corresponds to the size of the original C by changing the length along the longitudinal direction of the film F, for example, long size mark A of a A3 image P ₁
It consists of ₁ and a short size mark A ₂ for A4 image P ₂ . Further, as the size mark A, the width corresponding to the size of the original C is provided by changing the width along the width direction of the film F, and the size mark A is provided by changing the light transmission density between them. It is also possible to use those having distinctiveness by changing the number, color, various sizes, shapes, positions, etc.

Further, the imprinting position of the size mark A corresponds to the central portion of the image P as shown in FIG. 7 (1), and the image as shown in FIGS. 7 (2) and 7 (3). Various selections are made in the vicinity of the image P, in which the front end is aligned with the front end of P.

Further, as the relationship between the size mark A and the blip mark that has been conventionally used, as will be described later, there are a method of using each separately, a method of using both of them, and the like.

The size mark A looks like this.

Next, the imprinting mechanism will be described.

FIG. 1 and FIG. 4 show an example of the imprinting mechanism 34 relating to the size mark A having distinguishability by changing the length of the film F along the longitudinal direction.

The imprinting mechanism 34 is an upper plate having a light-shielding property of the base 1.
An opening 36 formed in 35, a shutter 37, a diffusion plate 38, and a
Light sources such as the first and second mark lamps 39 and 40 are provided. The opening 36 is formed in a rectangular shape so as to face the channel portion that is the side end portion of the film F. Diffuser 38
Is for making the light quantities from the first and second mark lamps 39, 40 uniform. The shutter 37 has a light-shielding property, and is movable along the conveyance direction of the document C, that is, the feeding direction of the film F.

Therefore, the light from the first and second mark lamps 39 and 40 is transmitted to the diffusion plate 3
8, the film F is projected and exposed from below through the opening 36,
The size mark A is imprinted. The width of the size mark A to be imprinted is set by the width of the opening 36, and its length is set by the position of one end of the shutter 37.

A rack 41 is fixedly mounted on the other end of the shutter 37. The rack 41 meshes with a pinion 42, and the pinion 42 is fixedly mounted on a motor shaft of a second motor M2 capable of rotating in the forward and reverse directions. Therefore, the shutter 37 is opened by the forward and reverse rotation of the second motor M2.
You will move in and out.

A mark plate 43 is attached to the central portion of the shutter 37, and the mark plate 43 is arranged in line with the sensors S3 or S4 or sensors.
It can be detected by S5. Therefore, the sensors S3, S4, S5
Thus, the position of the shutter 37 and the presence / absence and length of the size mark A to be imprinted are detected and determined. That is, for example, when the size mark A is not photographed, the opening 36 is completely shielded by the shutter 37 and the mark plate 43 is positioned so as to be detected by the sensor S3. When the document C is A4 size, the shutter 37 is positioned to block half of the opening 36 and the mark plate is used.
43 is located to be detected by sensor S4. Original C
In the case of A3 size, the shutter should be opened to open all openings 36.
37 is positioned at the retracted position, and the mark plate 43 is positioned so as to be detected by the sensor S5.

First, the imprinting mechanism 34 is not limited to the system using the mechanical shutter 37 as shown in the figure, but instead of this, a liquid crystal shutter whose light transmittance changes in accordance with an applied voltage is used in two areas or the like. It is also possible to use a method of partitioning into.

Secondly, the imprinting mechanism 34 is not limited to the system in which the shutter 37 and the first and second mark lamps 39 and 40 are combined as in the illustrated example, and a planar light-emitting body such as a light-emitting diode is provided in two areas or the like. A method of partitioning and using is also possible.

Thirdly, the imprinting mechanism 34 has an opening portion as shown in the figure.
In addition to the method in which 36 is divided into three stages of fully closed, half opened, and fully opened by the shutter 37 and two kinds of size marks A are imaged, the method shown in FIG. 5, for example, is also possible. That is,
The opening 36 may be divided into four stages of fully closed, 1/3 open, 2/3 open, and fully open by the shutter 37, and three types of marks, large, medium and small, may be imaged. In this case, three size marks A
However, as shown in FIG. 7 (3), even if the large mark is used as the blip mark B for the case retrieval and the medium mark and the small mark are used as the size marks A ₁ and A _2. Good. The image P is not captured at the position corresponding to the blip mark B for the case search.

Fourthly, the imprinting mechanism 34 in the illustrated example is built in the base 1, but it can be built in the camera head 6 as shown in FIG. That is, for example, light from the planar light-emitting body 44 that is divided into two areas and used may be projected and exposed from above onto the periphery of the image P on the film F via the lens 45. In this case, a mask or the like is provided between the imprinting mechanism 34 and the aperture 20 to shield each other from light.

The imprinting mechanism 34 has such a structure.

Next, the discrimination means and the like will be described.

On the conveyor belt 14 side of the feed roller 12 of the automatic feeding mechanism 9,
A sensor S6 is provided, and this sensor S6 detects the edge of the document C fed from the feed roller 12 to the conveyor belt 14. The sensor S6 shown in the figure is of a transmissive type, which is composed of a pair of light emitting elements such as light emitting diodes and a light receiving element such as a photodiode which face the original C from above and below.
It is of course possible to use a reflective type or the like. Further, a pulse generator such as an encoder is coaxially attached to the feed roller 12 which is rotationally driven at a constant rotation speed, so that the pulse generator generates a pulse corresponding to the feed amount of the document C.

The edge detection signal of the document C by the sensor S6 and the pulse signal corresponding to the feeding amount of the document C by the pulse generator are input to the microcomputer 46 for general operation control shown in FIG. 46 functions as a discrimination means and a control means as follows.

First, the size of the document C is determined. That is, the gate is opened / closed by the detection signals of the leading edge and the trailing edge of the document C, and the pulse count number proportional to the size of the document C is obtained by counting the number of pulses applied while the gate is open. can get. Therefore, by comparing this count number with a preset reference value, for example, an intermediate value between the count number of A3 and the count number of A4, it is determined whether the size of the document C is A3 or A4. Based on the result of this determination, the status of the corresponding size flag is set to, for example, 1,0.

As the counting method of the feeding amount of the document C, various other photoelectric methods, magnetic methods, and mechanical methods are possible in addition to the method using the pulse generator attached to the feeding roller 12 described above. Further, irrespective of the detection means using the pulse generator or the like and the sensor S6 for detecting the edge as described above, for example, on the base 1, the detection is ON for the document C of A3 and OFF for the document C of A4. The size of the document C can be easily discriminated also by a system in which a detecting device such as a sensor is provided at a fixed position and the microcomputer 46 or the like looks at the on / off state. In this method, the automatic feeding mechanism 9 is not incorporated in the base 1, a fixed document table is arranged on the base 1, and the document C is placed and positioned by hand on the document table. It is convenient to use in a micro camera.

The microcomputer 46 determines the size of the document C in this way.

Secondly, the microcomputer 46 controls the stop of the document C. That is, a signal is output based on the size determination result of the document C described above so that the conveyor belt 14 of the automatic feeding mechanism 9 is stopped after a predetermined time set for each size. Therefore, the document C on the transport belt 14 is stopped and positioned on the base 1 by, for example, the above-described centering method.

Thirdly, the feeding of the film F is controlled. That is, a signal for rotating the film feed roller 24 of the photographing mechanism 18 for a predetermined time is output based on the size determination result of the document C and the stored size of the previously photographed document C. Then, the film F is sent from the reel 21 on the supply side to the reel 22 on the take-up side by a predetermined amount.

Fourth, the aperture 20 is set. That is, based on the size determination result of the original document C and the current positions of the light-shielding plates 26 and 27 corresponding to the size of the previously captured original document C, for example, the first motor of the imaging mechanism 18 is used if necessary. A drive signal in an appropriate direction and amount is output to M1. Therefore, the aperture 20 is set to a size corresponding to the size of the document C.

Fifthly, the imprinting mechanism 34 controls the imprinting of the size mark A. That is, based on the above-described determination result of the size of the original C and the current position of the shutter 37 corresponding to the size of the previously captured original C, for example, the second motor of the imprinting mechanism 34 is used if necessary. A drive signal of an appropriate direction and amount is output to M2. So the shutter
37 is moved as necessary, the first mark lamp 39 and the second mark lamp 40 are turned on, and the size mark A corresponding to the size is imprinted around the image P of the film F through the opening 36. It will be.

The determination means and other control means are as described above.

In FIG. 1, reference numeral 47 is a shooting button provided on the base 1, and 48 is a space button for performing an idle feed. or
Reference numeral 49 is a switch for changing the necessity of the size mark A. That is, by switching the changeover switch 49, whether the imprinting mechanism 34 is used for imprinting the size mark A or for imprinting the blip mark B for the case search and the frame search. You can choose. Further, in FIG. 2, S7 is a sensor including a pair of a light emitting element and a light receiving element arranged corresponding to the set tray 7 in order to detect the presence or absence of the document C in the set tray 7.

The above is the description of the configuration.

Next, the operation and the like will be described.

9 to 14 are flowcharts showing the control of the embodiment, and the operation and the like will be described with reference to these figures.

FIG. 9 shows the basic control.

After initial setting in step, it is determined in step that the shooting button 47 is on. If the shooting button 47 is on, the process proceeds to the next step, and the presence or absence of the document C in the set tray 7 is determined based on the detection of the sensor S7. The presence / absence determination of the document C is repeated until the document C on the set tray 7 is exhausted, and if the document C is not present, the process returns to step.
When the document C is present, in the next step, the feed roller 12 and the conveyor belt 14 are turned on, the delivery roller 10 is also turned on, and the automatic feed mechanism 9 is operated such that the separation rollers 11 and 11 also function. Therefore, only one original C is sent from the set tray 7 to the conveyor belt 14 and further conveyed by the conveyor belt 14.

Then, in step, the size of the original C is discriminated. FIG. 10 shows this size discrimination routine.

In the size determination routine, first, the detection of the leading edge of the document C is determined in step. That is, the automatic feeding mechanism 9
When the leading edge of the document C fed by means of the sensor S6 passes through the sensor S6, the feed roller 12 is turned off and the feed roller 10 is also turned off at the step, and the counting operation of the pulse by the microcomputer 46 as the determination means at the step The process is repeated until the trailing edge of the document C is detected. When the trailing edge of the document C is detected by the sensor S6 in step, the previous size flag is stored in the nonvolatile RA as the previous size flag in step.
The size plug is newly set as well as stored in M. Then, in a step, the count number of the step is compared with a preset reference value.
When the count number is larger than the reference value, for example, A3, the status of the corresponding size flag in the step is set to 1, for example.
If the count number is smaller than the reference value, for example, A4, the status of the corresponding size flag is set to 0, for example.

The size discrimination routine of the document S in FIG. 10 is as described above.

Now, returning to the flow of FIG. 9, the feeding of the document S by the automatic feeding mechanism 9 is stopped in step. FIG. 11 shows the original S stop routine.

That is, it is first determined in step whether or not the status of the size flag is 1. In the case of 1, for example, when the size of the document C is A3, the timer for A3 is used in step.
When T ₁ is started and the set time from the detection of the trailing edge by the sensor S6 in the above step has elapsed, the timer T ₁ is incremented in step, and the transport belt 14 which has been traveling in step is stopped. If the status of the size flag is 0 instead of 1 in step, for example, the size of the document C is A4, the timer T ₂ for A4 is started in step, and when the set time elapses, the timer T _{2 in} step Time is up, and the conveyor belt 14 is stopped in steps. In this manner, the document C is conveyed by a predetermined amount according to its size by the conveyor belt 14 as shown by the imaginary line in FIG. 2, and is positioned and stopped at each stop position. In the illustrated example, the centering method is adopted as described above.

The original S stop routine of FIG. 11 is as described above.

Now, returning to the flow of FIG. 9, the film F is fed by a predetermined amount in the photographing mechanism 18 in step. FIG. 12 shows this film F feed routine.

First, as shown in FIG. 15, from the relationship between the size of the image P ₃ photographed last time and the image P ₄ photographed this time, the required feed amount of the film F is, for example, three types a, b, c. Therefore, the feed amounts a, b, and c are made to correspond to the drive time of the film feed roller 24, and this is controlled by timers Ta, Tb, and Tc. First, in step, the film feed roller 24 is rotationally driven at a constant speed by a drive source (not shown), and it is determined whether or not the status of the previous size flag stored in step is 1. If it is 1 or A3, it is then determined in step whether or not the status of the size flag of the original C this time is 1, and if 1 or A3, the timer Ta is turned on and off for a set time in step, As will be described later, in a step, the film F is fed by a predetermined amount a.

By the way, in step A4, the previous size flag is 0 instead of 1.
In this case, if the size flag of the original S at this time is judged to be 1 in step A3 and the corresponding timer Tb is turned on / off for a set time in step A3, the film F is fed by a predetermined amount b in step. . Even when the size flag of the original document C at this time is 0 instead of 1 and it is determined to be A4, the process proceeds to the same step as described above. In step A4, if the size flag of original C this time is 0 instead of 1, A4
If it is determined that the timer Tc
Is turned on and off for the set time, and in step, film F
Is sent by a predetermined amount C. In this way, the set time of the timer Ta or Tb or Tc is timed up in step, the film feed roller 24 is stopped in each case in step, and the film F is fed by a predetermined amount a, b or c. Become.

A pulse motor is used as a drive source of the film feed roller 24, and the amount of rotation thereof is controlled, so that the film F is supplied to a predetermined amount a, b, c without using the timers Ta, Tb, Tc as described above.
It is also possible to send it.

The film F feed routine of FIG. 12 is as described above.

Now, returning to the flow of FIG. 9, the aperture 20 of the photographing mechanism 18 is set in step. Figure 13 shows this aperture 20
The setting routine is shown. In this routine, it is confirmed whether or not the size of the original document C and the aperture 20 for determining the size of the image P correspond to each other, and if they do not correspond to each other, they are adjusted to correspond to each other.

First, in step, it is judged whether or not the status of the size flag is 1, and if it is 1, that is, A3, in the next step, the size of the previously photographed is A3.
When 33 is in the position detected by sensor S2, aperture 20 is properly set for A3 and the flow returns. In addition, the detection plate 33 is a sensor
If not detected by S2, first step
When the motor M1 is rotated counterclockwise, the light shielding plates 26, 27 move in the separating direction via the input gear 32, the fan gear 31, the pinion 30, the racks 28, 29, and the detection plate 33 is detected by the sensor S2 in a step, The first motor M1 is stopped in step. In this way the aperture 20 is set for A3 and the flow returns.

If the size flag is not 1 in step, that is,
In case of A4, in step, the size taken last time is
When the detection plate 33 is at the position detected by the sensor S1 due to A4 or the like, the aperture 20 is properly set for A4, and the flow returns. If the detection plate 33 is not detected by the sensor S1 in the step, the first motor M1 is rotated right in the step, the light shielding plates 26 and 27 move in the approaching direction, and the detection plate 33 is detected by the sensor S1 in the step. If detected, the first motor in step
M1 stops. In this way the aperture 20 is set for A4 and the flow returns.

The aperture 20 setting routine of FIG. 13 is as described above.

Now, the flow returns to FIG. 9, and mark setting is performed in step. FIG. 14 shows this mark setting routine. In this routine, it is confirmed whether or not the size of the document C and the position of the shutter 37 that determines the length of the size mark A correspond to each other, and if they do not correspond, the shutter 37 moves to correspond. To be done.

In this routine, the changeover switch 49
Whether or not the size mark A needs to be imprinted is determined by looking at the on / off state of the mark. If no, it is determined in step whether the mark plate 43 is detected by the sensor S3, and if it is detected. That is, the opening 36 is the shutter 37.
If it is completely shielded by, the flow returns as it is. Next, in the step, if the mark plate 43 is not detected by the sensor S3, the second motor M2 is rotated right in the step, the shutter 37 is moved leftward in the drawing through the pinion 42 and the rack 41, and the step When the mark plate 43 is detected by the sensor S3 at, the second motor M2 is stopped at step. In this way, the opening 36 is completely shielded by the shutter 37, the size mark A is not imprinted, and the flow returns.

When it is necessary to imprint the size mark A at the step, it is first determined at the step whether or not the status of the size flag is 1. In the case of 1, that is, in the case of A3, it is determined in step whether or not the mark plate 43 is detected by the sensor S5. If it is detected, that is, if the shutter 37 is at the retracted position, the opening 36 is in the fully open state, and the size mark A for A3 is set to be imprinted, the first and second steps are performed. Both the mark lamps 39 and 40 are turned on, and the flow returns. Next, when the mark plate 43 is not detected by the sensor S5 in the step, the second motor M2 is rotated left by the step, the shutter 37 is moved rightward in the drawing, and the mark plate 43 is detected by the sensor S5 in the step. If detected, the second motor M2 is stopped in step. In this way, the opening 36 becomes fully open for A3, and the first, second
The mark lamps 39 and 40 are turned on and the flow returns.

When it is determined in step S1 that the size flag is not 1, that is, when the document C is A4, it is determined in step S3 whether the mark plate 43 is detected by the sensor S4. And if detected, i.e. shutter
When 37 is in the intermediate position and the opening 36 is in the half-opened state and the size mark A for A4 is set for imprinting, the first mark lamp 39 is turned on in step and the flow returns. Then, in the next step, the mark plate 43 becomes
If it is not detected by, it is determined in step whether or not the mark plate 43 is detected by the sensor S5. If it is detected, the second step
The motor M2 is rotated right, and the shutter 37 moves leftward in the drawing. That is, it moves from the retracted position for A3 to the intermediate position for A4. On the contrary, when the mark plate 43 is not detected by the sensor S5 in step, the second motor M2 is rotated left in step and the shutter 37 is moved rightward in the drawing. That is, it moves from the position that shields the opening 36 to the intermediate position for A4. Now in steps like this,
When the mark plate 43 is detected by the sensor S4, the second motor M2 is stopped in step. Then, when the shutter 37 is at the intermediate position and the opening 36 is in the half-opened state and the setting for imprinting the size mark A for A4 is completed, the first mark lamp 39 is turned on in step and the flow returns. .

The mark setting routine of FIG. 14 is as described above.

Now, the flow returns to FIG. 9, and in step, the photographing mechanism 18
Will be used for shooting. That is, the lens shutter is opened for a predetermined time, and the original C is projected and exposed as the image P on the film F by the light of the illuminated illumination lamps 4, 4 and the like through the aperture 20 set in the step. In addition, the first mark lamp 39
Further, the size mark A is imprinted by the second mark lamp 40.

Then, in steps, the first mark lamp 39 and then the second mark lamp 39
The mark lamp 40 is turned off, the conveyor belt 14 of the automatic feeding mechanism 9 is turned on in the step, and the timers T ₃ and T ₄ are turned on and off for the set time in the step depending on whether or not the size flag is 1 in the step. As a result, the conveyance belt 14 conveys the document C by a predetermined amount, the photographed document C is ejected to the ejection tray 8, and the conveyance belt 14 is stopped in step.

Then, the flow returns to the step, and the next original C is fed.

The description based on the flowchart is as described above.

In this way, the size mark A is easily and easily imprinted on the film F around the image P in this manner.

Then, when the image P is enlarged and copied by a reader printer or a printer, the size and size of the image P can be easily detected. That is, for example, in the projection optical path in the roll film carrier part of the reader printer, the size mark A is detected by the detection means such as a channel sensor located opposite to the channel part of the film F.
Is easily detected, and the size of the image P can be easily determined based on the detection. Then, the copy paper suitable for the size is selected and fed. As the channel sensor or the like, a conventional one for the blip mark B can be easily diverted.

The above is the description of the operation and the like.

In the present embodiment, as described above, the original C photographed last time is used.
Is stored and the feed of the film F or the like is set by the confirmation, so that there is an advantage that the control is accurate and efficient.

"Effects of the Invention" As described above, the micro camera according to the present invention is
When capturing an image, size marks can be easily, quickly, accurately and efficiently imprinted around the image, and the size mark makes it easy to detect and determine the image size when enlarging and copying with a reader printer. The advantages of the present invention are remarkably large, for example, it has been simplified, its structure is simple, its structure is simple, and the problems existing in the conventional example are eliminated.
