[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reading device, and more particularly, to an image reading device for reading an image of a document by light from a light source applied to an area including an image recording range of the document on which the image is recorded. Regarding

[0002]

2. Description of the Related Art Recently, an image reading apparatus has been proposed in which an image recorded on a document such as a photographic film is optically read by an image reading means (for example, a reading sensor such as CCD).

In this image reading apparatus, image processing such as enlargement / reduction and various corrections is performed on digital image data obtained by reading.

A printer that receives image-processed digital image data forms an image on photographic paper with laser light modulated based on the digital image data.

In recent years, in addition to forming an image on photographic paper,
For example, digital image data is recorded on an optical recording medium such as a CD-ROM disc and delivered to customers.

For this reason, a recent image reading apparatus has a CD
-An optical recording device such as a ROM drive is attached.

[0007]

However, depending on, for example, the installation location of the image reading device, steady vibrations from the floor (so-called "moving vibrations") are transmitted to the optical recording device, or the image reading device is subject to the problems. If vibration (so-called “movement shock”) when operating the operation unit for performing the operation is transmitted to the optical recording device, there is a possibility that digital image data cannot be correctly recorded on the optical recording medium.

Further, the optical recording apparatus is electrically connected to the image reading apparatus main body by a connector. However, when a contact terminal of the connector causes a contact failure, digital image data is transferred to the optical recording apparatus. Couldn't communicate properly, and as a result,
There is a possibility that digital image data cannot be correctly recorded on the optical recording medium.

In consideration of such a fact, it is an object of the present invention to obtain an image reading apparatus capable of correctly recording digital image data on an optical recording medium.

An image reading apparatus according to claim 1, wherein an area including an installation member installed on a floor surface and an image recording range of an original document on which the image is recorded is installed on the installation member. An image pickup unit including an image reading unit that reads an image of a document by light emitted from a light source irradiated on the image pickup unit; a vibration isolation unit provided between the installation member and the image pickup unit to prevent transmission of vibration; An optical recording device, which is provided in the imaging unit and irradiates a recording medium for rotating the read image information with a light beam to record the image information, is characterized.

Next, the operation of the image reading apparatus according to the first aspect will be described.

The light emitted from the light source to the area including the image recording area of the document passes through the document, and the image reading means reads the image of the document by the transmitted light.

The image pickup unit having the image reading means is mounted on an installation member, and the installation member is installed on the floor surface.

Therefore, the image pickup unit provided with the image reading means is installed on the floor through the installation member.

Vibration isolation means is provided between the installation means and the image pickup unit to prevent transmission of vibrations from the floor surface.

For this reason, so-called color misregistration does not occur at the time of reading the original, and the image of the original can be read with high reading accuracy.

Further, in the optical recording device, the read image information is recorded by irradiating a rotating recording medium with a light beam.

In the optical recording apparatus, if vibration is transmitted during recording of image information, the image information may not be recorded correctly on the recording medium. However, in the present invention, the vibration isolator prevents the vibration from the installation means side. Since the light is absorbed, the vibration is not transmitted to the optical recording device, and the image information can be correctly recorded on the recording medium. The optical recording device of the present invention is, for example, a CD-R writer, a DVD-R writer,
A magneto-optical disk drive (Mo drive),
Other types of devices may be used as long as they are devices that record information on a rotating recording medium using a light beam.

According to a second aspect of the present invention, in the image reading apparatus according to the first aspect, the image pickup unit has a film carrier that conveys and holds a photographic film.
It is characterized by that.

Next, the operation of the image reading apparatus according to the second aspect will be described.

In the image reading apparatus according to the second aspect, the photographic film as the original is held by the film carrier and the image recorded on the photographic film can be read.

Since the film carrier is provided in the image pickup unit supported by the anti-vibration means, vibration of the film carrier is suppressed, so-called color misregistration or the like does not occur at the time of reading the original, and the original can be read with high reading accuracy. The image can be read.

According to a third aspect of the present invention, in the image reading apparatus according to the first or second aspect, an electrical component of the optical recording device and an electrical component of the image pickup unit are electrically connected to each other. A male connector having a plurality of male side contact terminals to be connected, and a female side electrically connected to the other of the electrical component of the optical recording device and the electrical component of the imaging unit and corresponding to the male contact terminal. A female connector having a contact terminal, and in the male connector,
An upper terminal row in which a plurality of male contact terminals having different functions are arranged in the lateral direction, and a plurality of male contact terminals arranged below the upper terminal row and having the same function as the upper terminal row are arranged in the lateral direction. In the female connector, an upper terminal row in which a plurality of female contact terminals having different functions are laterally arranged, and the upper terminal row arranged below the upper terminal row are provided. And a lower terminal row in which a plurality of female contact terminals having the same function are arranged in the lateral direction.

Next, the operation of the image reading apparatus according to the third aspect will be described.

In the image reading apparatus according to the third aspect, the electrical components of the optical recording device and the electrical components of the image pickup unit are:
By connecting the male connector and the female connector, the male-side contact terminal and the corresponding female-side contact terminal come into contact with each other and are electrically connected to each other.

By the way, a plurality of male-side contact terminals and female-side contact terminals are arranged in the lateral direction (so-called when the connector is mounted sideways), and the upper surface of the male-side contact terminal serves as the contact portion. In this case, when dust is placed on the male contact terminal, poor contact with the female contact terminal may occur.

When the lower surface of the male contact terminal is the contact portion, the upper surface of the female contact terminal is the contact portion. Therefore, when dust is placed on the female contact terminal, poor contact with the male contact terminal may occur.

In the image reading device according to a third aspect of the present invention, in the male connector and the female connector, lower terminals in which a plurality of contact terminals having the same function as the upper terminal row are laterally arranged below the upper terminal row, respectively. Since the rows are arranged, for example, when one of the male contact terminals of the upper terminal row of the male connector has a poor contact, electrical connection is secured in the lower terminal row, and the lower terminals of the female connector are secured. When connection failure occurs in any of the female-side contact terminals in the row, electrical connection is secured in the upper terminal row, and it is possible to prevent image information recording failure due to contact failure.

According to a fourth aspect of the present invention, in the image reading apparatus according to any one of the first to third aspects, the image reading device is provided with an operation unit capable of operating the image reading unit. It is characterized in that a vibration isolation means for preventing transmission of vibration is provided between the image reading means and the image reading means.

Next, the operation of the image reading apparatus according to the fourth aspect will be described.

In the image reading device according to the fourth aspect, the image reading means can be operated through the operation section by the operation of the operator.

When the operator operates the operating section, the installation member may vibrate. However, since the anti-vibration means is provided between the operating section and the image reading means, this vibration affects the image reading means. Transmission is prevented by the anti-vibration means.

For this reason, so-called color misregistration does not occur at the time of reading the original, and the image of the original can be read with high reading accuracy.

In the present invention, the vibration isolator is preferably an elastic body.

When vibration is input, the elastic body is elastically deformed,
The internal friction of the elastic body converts the energy of vibration into the energy of thermal motion and dissipates it. By using an elastic body as the vibration isolator, the configuration becomes simple.

The elastic body is preferably rubber.

Rubber has a large internal friction as compared with other elastic bodies (for example, metal springs).

Therefore, by adopting rubber as the elastic body, the conversion efficiency from the energy of vibration due to internal friction to the energy of thermal motion becomes higher than that when other elastic bodies are used, and the vibration is shorter. Decays over time, so
Anti-vibration can be more effectively performed.

The image data output from 6 is recorded on the CD-R.

The CD-R writer 170 is attached to the upper surface of the film carrier 38.

A male connector 172 is attached to the back surface of the film carrier 38.

On the entire surface of the casing 44, a female connector 174 fitted with the male connector 172 is attached at a position facing the male connector 172.

As shown in FIG. 11, a male connector 172 is provided.
Has a convex portion 176 formed to be long in the lateral direction.

On the upper surface side of the convex portion 176, a plurality of male side contact terminals 178 connected to the electrical components of the film carrier 38 and the CD-R writer 170 by wiring not shown.

Also, on the upper wall surface side of the concave portion 180, a plurality of female side contact terminals 182 which are connected to the image processing section 16 by wiring (not shown) and have the same function as the terminal row on the upper wall surface side are arranged in the longitudinal direction. They are arranged in a line at regular intervals along the line.

The convex portion 176 of the male connector 172
Is inserted into the concave portion 180 of the female connector 174,
The male contact terminal 178 corresponds to the female contact terminal 1
Contact 82. (Operation) Next, the operation of the line CCD scanner 14 of the present embodiment will be described.

In order to read the image on the photographic film 22 by the line CCD scanner 14, the operator first loads the photographic film 22 on the film carrier 38.

Then, the film carrier 38 loaded with the photographic film 22 is set on the work table 27.

As a result, the photographic film 22 is set on the line CCD scanner 14 via the film carrier 38.

Of course, the film carrier 38 may be set on the work table 27, and then the photographic film 22 may be loaded on the film carrier 38.

The light emitted from the light source section 30 is made into slit light by the diffusion box 40, and the photographic film 22
Through.

Further, this light passes through the lens unit 50 and enters the line CCD 116, and the photographic film 22
Image is read.

When the image on the photographic film 22 is being read, for example, the floor surface F on which the work table 27 is installed.
When walking (see FIGS. 2 and 3) or the like, the floor surface F vibrates (so-called “motion vibration”).

This vibration is transmitted to the work table 27 via the casters 124 and the stopper 126.

The work table 27 also vibrates due to the operation of each member constituting the image reading apparatus 10.

However, the support frame 45 and the housing 1
Since a gap 160 is formed between the support table 45 and the work table 28, the vibration of the work table 27 is not transmitted to the support frame 45 and the support frame 45 is isolated from vibration.

Further, the vibration of the work table 27 causes the vibration isolating member 142 to vibrate. In this case, the vibration isolating member 142 is used.
Since the vibration damping rubber body 144 constituting the elastic deformation elastically dissipates the vibration energy as heat energy, the vibration is not transmitted to the support frame 45 and the support frame 45 is vibration-insulated.

As described above, the support frame 45 has the gap 16
0 and the anti-vibration member 142 provide anti-vibration,
Since the reading unit 43 as a whole is also isolated from vibrations, for example, the support frame 45 and the like are not slightly deformed by vibration, and the line CCD 116 and the lens unit 50 and the photographic film 22 have a relatively constant positional relationship. To be kept.

Therefore, for example, so-called color misregistration does not occur during reading, and the original of the photographic film 22 can be read with high reading accuracy.

Further, during the image reading, the operator operates the keyboard and the mouse to apply intermittent impacts (so-called “motion impacts”) to the housing 128, and the housing 128 vibrates.

However, the housing 128 and the housing 1
Since the gap 132 is formed between the housing 130 and the housing 30, the housing 130 is isolated from the housing 128, and the vibration of the housing 130 is small.

Further, the support frame 45 is the housing 1
Since the gap 160 and the anti-vibration member 142 are applied to 30 to prevent vibration, the reading unit 43 as a whole is also anti-vibrated, and the original of the photographic film 22 can be read with high reading accuracy without causing color misregistration or the like. You can

Particularly, in this embodiment, the vibration-proof member 142 is used.
Is composed of a vibration-proof rubber body 144 made of vulcanized rubber. Since vulcanized rubber generally has large internal friction, vibration can be effectively damped.

In addition, the vibration characteristics of the anti-vibration rubber body 144 have a high frequency (for example, 10) that particularly affects the image reading accuracy in the line CCD scanner 14 as in the present embodiment.
It is also possible to have a vibration characteristic such that vibrations of 0 Hz and its vicinity) are effectively damped.

In the CD-R writer 170,
If vibration is transmitted during image information recording, the image information will
-It may not be possible to record correctly on the R disc,
In the present invention, the film carrier 3 which is hardly affected by vibration
Since the CD-R writer 170 is attached to the No. 8, image information can be correctly recorded on the CD-R disc.

Further, in the male connector 172 and the female connector 174, since the terminal row having the same function as the upper terminal row is arranged on the lower side of the upper terminal row, for example, any one of the upper terminal row of the male connector 172 is arranged. Even if the male side contact terminal 178 has a poor contact, the electrical connection is ensured in the lower terminal row, so that the image information is correctly recorded on the CD-
It can be recorded on an R disc.

Even if one of the female contact terminals 182 of the lower terminal row of the female connector 174 has a poor connection, the electrical connection is secured in the upper terminal row. It can be correctly recorded on a CD-R disc.

In the above description, the vibration isolation means 1
As an example, the vibration-proof member including the vibration-proof rubber body 144 made of vulcanized rubber has been described, but it goes without saying that the vibration-proof means is not limited to this.

For example, the anti-vibration member is replaced by vulcanized rubber,
It may be formed of another elastic rubber or resin.

Further, for example, another elastic body such as a coil spring may be used. Coil springs are generally
The internal friction is lower than rubber, but in this case, in addition to the coil spring, it is possible to further enhance the vibration damping effect by providing a damping means such as a damper that damps the vibration energy by the flow resistance of the fluid. become.

As another example of the vibration isolation means, the gap 13
Although 2 and 160 are mentioned, it goes without saying that the gaps 132 and 160 are not limited to the above-mentioned configuration.

For example, the installation frame 122 may be divided into two corresponding to the housings 128 and 130, and the gap 132 may be configured so that the work table 27 is completely separated into two.

By completely separating the work table 27 into two in this way, the direct vibration transmission path from the keyboards 12A, 12B and the mouse 20 to the support frame 45 is completely separated, and The image can be read with high reading accuracy by effectively isolating the support frame 45 from vibration.

Further, the position forming the gap is not limited to the above position.

In short, a position where these vibrations can be prevented from being transmitted to the reading unit 43 with respect to the motion vibrations from the floor surface F and the vibrations caused by the operation shocks caused by the operation of the keyboards 12A, 12B and the mouse 20 of the operator. If

For example, it is possible to form a gap between the installation frame 122 and the housing 130 so that vibration from the floor surface is not transmitted to the reading section 43.

During the transportation of the photographic film 22, the CD
-It is preferable to stop recording by the R writer 170.

Further, although the CD-R writer 170 is attached to the film carrier 38 in the above embodiment, the present invention is not limited to this, and if the member is supported by the vibration isolator 142, the solid line and the solid line in FIG. You may attach to other parts, as shown with a two-dot chain line.
