Further, as shown in the main body of the image reading apparatus in FIG. 6, the viewer 11 is provided with a screen 11a on which an image of the film 100 is projected and an information input section 11b for inputting information necessary for the reading operation. Therefore, before the image is read by the sensor 104, the image of the film 100 can be optically projected on the screen 11a to check the image and set the reading area. (Second conventional example) Conventionally, in order to read an image of a transparent original such as a photographic film in an image forming apparatus such as an electrophotographic apparatus or an electrostatic recording apparatus, the image is formed by an electric signal by a film scanner apparatus or the like. A method of communicating with the forming apparatus has been proposed and put into practical use.

As an image reading apparatus of this type, there is an image reading apparatus whose outline is shown in FIG. In the figure, a film 300 as a transparent original includes an optical system 302 including a light source 301 and a condenser lens.
The image light, which is the transmitted light, is projected through a projection lens 303 onto an image reading sensor 304 such as a CCD as a reading element, and the image reading sensor 304 moves the entire image while moving. It reads and converts image light into electric signals.

At that time, as shown in the main body of the image reading apparatus in FIG. 14, the viewer 211 is provided with a screen 211a on which an image of the film 300 is displayed and an information input section 211b for inputting information necessary for the reading operation. Has been.

Normally, before the image is read by the image reading sensor 304, the image on the film 300 is optically projected on the screen 211a to confirm the image and set the reading area. In order to reduce the size of the device, the portion for optically projecting is eliminated, and the image is directly read by the image reading sensor 304, and the confirmation image is displayed on the electronic viewer or the like.

Further, there is also an apparatus capable of flowing and reading the image of the film 300 when the carrier 201 capable of holding the film 300 is mounted on the image reading apparatus. (Third conventional example) Conventionally, in order to read an image of a transparent original such as a photographic film in an image forming apparatus such as an electrophotographic apparatus or an electrostatic recording apparatus, the image is formed by an electric signal by a film scanner apparatus or the like. A method of communicating with the forming apparatus has been proposed and put into practical use.

As an image reading apparatus of this type, there is an image reading apparatus whose outline is shown in FIG. The film 500 as a transmissive original is irradiated with light from a light source 501 through an optical system 502 including a condenser lens and the like, and image light which is transmitted light is projected onto the projection lens 50.
The image is projected onto an image reading sensor 504 such as a CCD as a reading element via the image reading unit 3, and the image reading sensor 504 reads the entire image while moving and converts the image light into an electric signal.

Further, in this image reading device, when the carrier member capable of holding the film 500 is inserted into the magazine part for guiding the image reading device, the film 5 is held.
It is possible to scan and read 00 images.

As shown schematically in FIG. 18, an image reading sensor 504 such as a CCD is stopped at a predetermined position, and a film is placed in front of light emitted from a light source 501 through an optical system 502 including a condenser lens. By moving 500, the entire image light projected is flowed to the image reading sensor 504 and read.

The entire image reading apparatus is as shown in FIG. The image reading apparatus main body 412 is detachably provided with a magazine portion 410 for guiding the carrier member to the main body, and has a hole 410a for inserting the carrier member. Further, the image reading device main body 412 includes
The viewer unit 411 is provided. The viewer unit 411 is provided with a screen 411a on which an image of the film 500 is displayed and an operation unit 411b for inputting information necessary for reading operation. The screen 411a is a film 500
Although it is possible to project the image optically, the image is displayed by communicating with an electronic (liquid crystal) screen 11a by an electric signal recently due to cost reduction and downsizing of the device. (Fourth Conventional Example) Conventionally, in order to make an image forming apparatus such as an electrophotographic apparatus or an electrostatic recording apparatus read an image of a transparent original such as a photographic film, the image is formed by an electric signal by a film scanner apparatus or the like. A method of communicating with the forming apparatus has been proposed and put into practical use.

The entire image reading apparatus is as shown in FIG. The image reading device main body 612 has a hole 610a for inserting a carrier member.

The screen 611a can optically project the image of the film 700, but recently, due to cost reduction and downsizing of the device, an image is displayed by communicating with an electronic (liquid crystal) screen 611a by an electric signal.

An image reading apparatus of this type is constructed as shown in FIG. A film 700 as a transmissive original is irradiated with light from a light source 701 through an optical system 702 including a condenser lens and the like, and the transmitted image light is imaged by a CCD or the like as a reading element through a projection lens 703. The image reading sensor 704 is projected on the sensor 704, reads the entire image while moving, and converts the image light into an electric signal. After the image is displayed on the screen 611a by the pre-scan, the information necessary for the reading operation, for example, the operation of setting the area is started to start the full-scale reading of the film image.

[0015]

(First Problem) However, the prescan for image confirmation in the first conventional example described above reduces the size of the image reading device and simplifies the image information processing operation. It is becoming more common to display the information on the electronic viewer 11 such as liquid crystal or the like, which is electrically converted by the sensor 104, rather than being directly projected on the screen 11a. Therefore, the screen 11a is used for image confirmation.
There is a drawback that it takes time to pre-scan to display in. (Second Problem) However, when the carrier 201 capable of holding the film 300 in the second conventional example is mounted on the image reading device, the image of the film 300 is scanned in the direction of movement of the carrier 201 according to the principle of flow scanning. Is limited to one way. Therefore, when selecting one of the plurality of image frames of the film 300, if the target image frame is ahead of the image reading position in the traveling direction of the carrier 201, the carrier 201 is returned to the rear side and then the magazine. Since it had to be reinserted into the part, there was a drawback that the operability was extremely poor. (Third Problem) However, in the third conventional example, the carrier member that holds the film 500 is inserted into the magazine part that guides the image reading device, and the image of the film 500 is scanned and read, and the image is displayed on the electronic screen 411a. Is displayed, there is a limit to the speed at which the image reading sensor 504 can read the image on the film 500.

That is, when the carrier member holding the film 500 is inserted into the magazine section at an unnecessarily high speed,
The image reading sensor 504 cannot read all the image information of the film 500, and the image shrinks in the flow reading direction. When the contracted image is displayed on the screen 411a, there is a drawback that the operability becomes extremely poor due to the information necessary for the reading operation, for example, the setting of the area. (Fourth Problem) However, in the fourth conventional example, since the image pre-scan for image confirmation is converted into an electric signal by the image reading sensor 704 such as CCD and displayed on the electronic screen 611a such as liquid crystal, It takes some time to display an image. Therefore, there is a problem in selecting an image from some film frames. For example, when the image of the first frame of the film is read, the image of the second frame is read, the image displayed on the screen 611a is judged, and the first frame is selected, the image is read again. If the sensor 704 does not read the image of the first frame, 1 is displayed on the screen 611a.
The frame image cannot be displayed. Thus, there is a drawback in that the operability is poor. (First Object) The first invention is made to solve the first problem, and an object thereof is to provide an image reading apparatus capable of shortening the time required for prescan for image confirmation. To provide. (Second object) The second invention is made to solve the second problem. The object is to move the carrier member either forward or backward with respect to the magazine part for guiding the main body. Another object of the present invention is to provide an image reading device capable of displaying an image correctly on the image information means and improving operability. (Third object) A third invention was made to solve the third problem, and an object thereof is to improve information necessary for reading operation, for example, operability such as setting of an area. An object of the present invention is to provide a possible image reading device. (Fourth object) The fourth invention is made to solve the fourth problem, and an object thereof is to provide an image reading apparatus capable of improving operability.

[0018]

(Embodiment of the First Invention) The first invention of the present application will be described below with reference to the illustrated embodiment. 1 and 2
Shows an image reading method of an embodiment of the first invention of the present application.

First, as a basic operation, a film 100 as a transparent original is set at a predetermined position, and light is emitted from a light source 101 through an optical system 102 including a condenser lens, and the transmitted image light is a projection lens. 10
The image is projected onto the image reading sensor 104 such as CCD as a reading element via the image reading unit 3, and the entire image projected is read while the image reading sensor 104 moves.

Then, the projected image light is converted into an electric signal to communicate with the image forming apparatus, or an image is displayed on the viewer 11. At this time, whether the image information of the transparent original film 100 is displayed vertically or horizontally for displaying on the screen 11a. Since conventionally, the image information is optically projected, the carrier member is used as shown in FIG. There was a vertical insertion hole 10a and a horizontal insertion hole 10b for inserting a certain carrier 1, but since the image light to be displayed can be rotated because image light is converted into an electric signal and communicated, the insertion hole is It's good only in one direction.

In the first invention of the present application, only the horizontal insertion is made in accordance with the moving direction of the image reading sensor 104. Further, it is possible to input necessary information such as the setting of the reading area from the information input unit 11b to the confirmation image displayed on the screen 11a. The image displayed on the screen 11a at that time is slightly worse than the image communicated to the image forming apparatus as long as the information inputting work is possible, so that there is no problem. Therefore, the image reading sensor 1
It is not necessary to read finely and accurately while moving 04 in the prescan for image confirmation.

Therefore, as shown in FIG. 2, the image reading sensor 104 is stopped at a predetermined position and the image can be moved and read by inserting the film 100. The carrier 1 has a film 10 as shown in FIG.
There is a window 4 for entering 0, and there is a hole 2 for a sensor indicating the position of the carrier window 4. The sensor hole 2 is detected by a sensor 3 built in a magazine 10, which is a magazine unit. Further, the carrier 1 is provided with a rack gear 5, and the carrier 6 is constituted by the gear 6 and the rotary encoder 7.
Detect the movement amount of.

When the carrier 1 is inserted into the magazine 10, the position of the carrier window 4, that is, the position of the film 100 can be known from the sensor hole 2 and the sensor 3 of the carrier 1. Then, from the edge of the film 100, the image reading sensor 104 stands still at a predetermined position, and the carrier 1
Read the projected image light that moves with the insertion of.

Further, the rack encoder 5 and the gear 6 rotate the rotary encoder 7 when the carrier 1 is inserted, and the amount of movement of the carrier 1 in the feeder direction can be known. Based on the detected value, the reading of the image light moving on the image reading sensor 104 is controlled.

As a result, even if the moving speed of the carrier 1 fluctuates midway or is extremely fast or slow, it can be read evenly according to the position of the image on the film 100 in the sender direction, and the original document can be read. It is possible to display an accurate image on the screen 11a, which is not a partial image in which the partial image is expanded or contracted in the sender direction as compared with the image in FIG.

Further, a second embodiment of the first invention of the present application will be described with reference to FIG.

In order to detect the movement amount of the carrier 1,
The carrier 1 is provided with a slit portion 8 and the magazine 10 is provided with a built-in photo interrupter 9. The film 100 is obtained in the same manner as in the first embodiment described above.
Of the film 100 in the position of the carrier and the direction of the carrier 1
You can see the amount of movement.

Even if the speed at which the carrier 1 is inserted into the magazine 10 fluctuates, the detection value obtained by the photointerrupter 9 and the slit portion 8 of the carrier 1 causes the reading of the image light moving on the image reading sensor 104. To control.

As a result, the first aspect of the first invention of the present application described above
The same effect as that of the embodiment can be obtained, and an accurate image can be displayed on the screen 11a. (Embodiment of the Second Invention) The second invention of the present application will be described below with reference to the illustrated embodiment.

First, as shown in FIG. 10, a film 300 as a transparent original is set at a predetermined position, and light is emitted from a light source 301 through an optical system 302 including a condenser lens and the like, and the transmitted image light is image light. A certain image light is projected through a projection lens 303 onto an image reading sensor 304 such as a CCD as a reading element, and the image reading sensor 304 reads the entire projected image while moving in the arrow direction.

Then, the projected image light is converted into an electric signal for communication with the image forming apparatus, or an image is displayed on the viewer 211.

On the other hand, in order to read the original image, the conventional method shown in FIG.
As shown in FIG. 4, the holes for inserting the carrier 201 in the magazine 210 are provided for the vertical insertion hole 210a and the horizontal insertion hole 21.
Although it has 0b, since image light is converted into an electric signal and image information can be rotated, the insertion hole is only required in one direction.

If the carrier 201 is provided so as to be movable in the scanning direction of the image reading sensor 300, the original can be read by scanning when the carrier 201 is inserted into the magazine section.

FIG. 7 shows the magazine 210 and the carrier 2.
01 is shown. Film 300 for carrier 201
There is a window 204 into which the carrier window 204 is inserted, and sensor holes 202 indicating the position of the carrier window 204 are provided on the left and right, respectively, and sensor holes 2 indicating the positions for the adjacent carrier windows 204
It is also used as 02. And the sensor 20
3 is detected. Further, the carrier 201 is provided with a rack gear 205, and the amount of movement of the carrier 201 and the gear 2 are controlled by the gear 206 and the rotary encoder 207.
The moving direction of the carrier 201 can be detected by the rotation direction of 06.

From these, the positions of the film 300 in the left and right end portions of the film 300, the feed direction of the carrier 201, and the feed direction can be known. Therefore, when the carrier 20 is inserted into the magazine 210 in the same direction as the scanning direction of the image reading sensor 304 as shown in FIG. To a predetermined position of the carrier 203 from the sensor 203 position,
That is, the position of the film 300 is detected, the movement amount is detected by the rotary encoder 207, the image information is controlled and read, and the carrier 201 is moved in the direction opposite to the scanning direction of the image reading sensor 304 which displays the image as it is on the screen 211a. When the insertion into the magazine 210 is detected by the rotation direction of the rotary encoder 207, as shown in FIG.
4 is moved to a second predetermined position and made to stand still, the image information is controlled and read in the same manner as described above, and the read image is displayed as a left-right mirror image.

Next, the reason why the image read here is displayed in the left-right direction will be described. FIG. 13 shows an image when a document is read by scanning the image reading sensor 304 as shown in FIG.

FIG. 13A shows an image on the film 300, which is projected on the scanning surface of the image reading sensor 304 via the projection lens 303 as shown in FIG. 13B. The image is read by scanning the image reading sensor 304. That is, the image is read from the A direction to the B direction.
It becomes like 3 (c).

As shown in FIG. 8, each image in the case where the carrier 201 is moved in the same direction as the scanning direction of the image reading sensor 304 and is flow-read is shown in FIG.

FIG. 11A shows an image on the film 300, which is similarly projected on the scanning surface of the image reading sensor 304 as shown in FIG. 11B and moves on the image reading sensor 304. That is, the image is read from the A direction to the B direction, as shown in FIG.
The same as the one read by the scanning of the image reading sensor 304.

Further, as shown in FIG. 9, each image in the case where the carrier 201 is moved in the direction opposite to the scanning direction of the image reading sensor 304 and is flow-read is shown in FIG.

FIG. 12A shows an image on the film 300, which similarly moves on the image reading sensor 304 while being projected on the scanning surface of the image reading sensor 304 as shown in FIG. 12B. That is, this time, since the image is read from the B direction to the A direction, the result is as shown in FIG. 12C, and the left and right are opposite to those read by the scanning of the image reading sensor 304. Therefore, it is necessary to display the read image on the screen 211a as a mirror image in which the left and right are reversed.

Further, by detecting the amount of movement by the rotary encoder 207 and controlling the reading of the image light moving on the image reading sensor 304 based on the detected value, the moving speed of the carrier 201 fluctuates on the way. Even if it is extremely fast or slow, it can be read evenly according to the position of the image on the film 300 in the sender direction, and a partial image may be stretched or shrunk in the sender direction compared to the original image. It can read accurate images that are not rough.

Since the left and right ends of the carrier window 204 of the carrier 201 can be confirmed by the sensor holes 202 and the sensors 203 on the left and right sides, it is possible to cope with a change in the moving direction of the carrier 201 for each frame of each film image. . (Embodiment of the third invention) FIG.
This will be described with reference to FIGS. FIG. 15 shows the third embodiment of the present application.
3 shows the inventive magazine part and carrier member. The carrier 401, which is a carrier member, holds the film 500 and has a carrier window 404 for projecting an image thereof. There is a sensor hole 402 that indicates the position of the carrier window 404, and the sensor hole 402 is a position sensor 40 built in a magazine 410 that is a magazine unit.
3 is detected.

In order to detect the amount of movement of the carrier 401, a slit portion 408 is provided on the carrier 401, and a photointerrupter 409 built in the magazine 410 detects it. When the carrier 401 is inserted into the magazine 410, the position of the carrier window 404, that is, the position of the film 500 can be known from the sensor hole 402 and the position sensor 403 of the carrier 401.

From the edge of the film 500, the image reading sensor 504 reads the projected image light that moves when the carrier 401 is inserted. Further, the carrier 401 is provided with a rack gear 405, and a gear 406 is provided.
It is connected to the damper 407 via. Oil is sealed in the damper 407, which serves as a load for the rotation of the gear 406. Therefore, when the carrier 401 is inserted into the magazine 410, the load resistance is proportional to the speed,
The carrier 401 cannot be inserted at an extremely high speed.

As a result, the moving speed of the carrier 401 is set to be equal to or lower than the scanning speed at which the image reading sensor 504 moves and reads the image on the film 500.

In the third invention of the present application, when the carrier 401 is inserted into the magazine 410, it becomes as shown in FIG.

FIG. 16 (a) shows an image on the film 500, and since the carrier 401 is moved at a slow speed, it can be read by the image reading sensor 504 as shown in FIG. 16 (b).

However, even if the amount of movement of the carrier 401 fluctuates in the middle, the image on the film 500 is controlled to be read evenly according to the position in the direction of the sender and the image information is partially scraped off. 16C, an image as shown in FIG. 16C can be created and displayed on the screen 411a, so that an image similar to the image on the film 500 can be obtained.

If the third invention of the present application is not applied,
When the carrier 401 is inserted into the magazine 410, the speed becomes too fast, and the result is as shown in FIG.

FIG. 17A shows an image on the film 500, which is read by the image reading sensor 504 as shown in FIG. 17A because the carrier 401 is moved at a high speed. Therefore, the image information cannot be controlled and is displayed on the screen 411a in FIG.
It becomes like (c). (Embodiment of the Fourth Invention) An embodiment of the fourth invention of the present application will be described below.

FIG. 21 shows a magazine portion and a carrier member according to the fourth invention of the present application. A carrier 601 which is a carrier member holds a film 700 and has a carrier window 604 for projecting an image thereof. There are positioning holes 602 indicating the positions of the carrier windows 604,
The distance A between the positioning holes 602 is equal to the distance between the carrier windows 604, and the number of the positioning holes 602 is one more than the number of the carrier windows 604, that is, the number of transparent originals to be a film.

As a result, the positioning holes 602 are arranged on both sides of each carrier window 604. The positioning hole 602 is detected by two position detection sensors 603 built in a magazine 610 which is a magazine unit, and
The distance B between the position detecting sensors 603 is longer than the distance A between the positioning holes 2 (B> A). When the magazine window 605 of the magazine 610 and the carrier window 604 are aligned with each other, the right position detection sensor 603a and the right positioning hole 602a of the carrier window 604 are arranged so as to overlap, and the left position detection sensor 603b and the carrier window 604 of the carrier window 604 are arranged. The left positioning hole 602b does not match.

When the carrier 601 is inserted into the magazine 610, the positioning holes 602 of the carrier 601 cross the front of the two position detection sensors 603 incorporated in the magazine 610 at different phases. Thereby, the inserting direction of the carrier 601 is detected, and the positioning hole 6
The order of the carrier windows 604 is detected depending on how many times 02 crosses.

When the first carrier window 604, that is, the film of the first frame is set at the image reading position, the image is read by the image reading sensor 704 and displayed on the screen 611a. When the carrier 601 is moved and the film of the second frame is set at the image reading position, the image of the first frame is stored in the memory, the image of the second frame is read and displayed on the screen 611a, and so on. Go on.

Here, when the carrier 601 is moved in the opposite direction to return to the film in which the image is previously stored in the memory, for example, when returning from the second frame to the first frame, the image of the first frame is displayed. Is called from the memory and displayed on the screen 611a. As a result, the image of the film frame at the image reading position and the image displayed on the screen 611a become the same.

FIG. 22 shows a block diagram of the above-mentioned fourth invention of the present application. Here, the image displayed on the screen 611a does not formally communicate with the image forming apparatus,
If the information required for reading operation can be input, there is no problem even if it is a little bad. The photographic film, which is a transparent original, is usually divided into 6 frames by a print service or the like. Therefore, the capacity for memory is quite small. For example, the A4 size normally requires about 192 kbytes, but the present invention can also use 10 kbytes or less. The operation of the fourth invention of the present application is shown in a simple flowchart in FIG.

Further, another embodiment of the fourth invention of the present application will be described.

In the image reading device, when the carrier member is guided to the image reading position by the magazine part,
Some scan the film, which is a transparent original, to scan it,
It is particularly effective when the fourth invention of the present application is carried out in this system. First, a brief explanation of the flow-through reading will be given.

In FIG. 25, the image reading sensor 7
04 is stopped at a predetermined position, and the film 700 held by the carrier 601 is inserted in the direction of the arrow in front of the optical system.
It is projected on 4 and moves. This allows the entire image to be read. When the carrier 601 is inserted in the opposite direction, it becomes as shown in FIG. The image reading sensor 704 is shown in FIG.
The film 700 is stopped at a predetermined position in the opposite direction to 5
Read the image.

However, since the scanning direction of the image reading sensor and the moving direction of the film 700 are opposite to each other, it should be noted that the read image is a mirror image of the image on the film 700, which is the left-right reverse.

FIG. 24 shows a magazine part and a carrier member. 21 is the same as the magazine part and the carrier member described in FIG. 21 of the first embodiment, and further, the carrier 601.
In order to detect the amount of movement of the carrier 601, a slit portion 608 is provided in the carrier 601 and a photo interrupter 609 built in the magazine 610 detects the amount.

When the carrier 601 is inserted into the magazine 610, the positioning hole 602 of the carrier 601 passes in front of the position detection sensor 603 of the magazine 610, and the image of the film of the first frame is read. On the way, that is, during the flow reading, since the movement amount of the carrier 601 can be measured by the slit portion 608 and the photo interrupter 609, the image being read is displayed on the screen 611a from the end while controlling the image during the reading. Go on. Before the entire image is displayed on the screen 611a, the operator can confirm what is in the first frame by only displaying a part of the image and can proceed to the next.

When the carrier 601 is further moved and the film of the second frame is tried to be read, the image of the first frame is stored in the memory, and so on. Here, when returning from the second frame to the first frame, in the case of flow scanning, the image reading sensor 704 is used as described above.
Since the insertion direction of the carrier 601 is reversed,
5 must move to the position of FIG. Alternatively, the carrier 601 must be pulled back once and then plugged in again.

Therefore, the image of the first frame is retrieved from the memory and displayed on the screen 611a. As a result, the image of the film frame at the image reading position and the image immediately displayed on the screen 611a become the same. Therefore, the same effect as that of the first embodiment of the fourth invention of the present application can be obtained.
