Abstract

PURPOSE:To improve the handling of the mount base by pressing a pressure part which can deform elastically and freely and raising a grip part. CONSTITUTION:When the mount base 10 is detached from an original platen 32, an operator presses pressure parts 18a and 18b against the side of the original platen 32 with finger. Consequently, the pressure parts 18a and 18b deform elastically into a nearly flat plate shape and grip parts 20a and 20b provided thereto integrally are swung and displaced so that while one-end sides of the grip parts 20a and 20b are made to abut substantially on the top surface of the original platen, the other-end sides are raised. The operator can, therefore, easily grip those grip parts 20a and 20b. Consequently, the handling can be improved.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a handle for a mounting table and an image scanning device using the handle, and more specifically, for example, a mounting table for holding a document on a document table. The present invention relates to a handle for a mounting table that allows the handle provided on the platform to be raised with a single touch, thereby making it easy to handle, and to an image scanning device using the same.

[Background of the invention] For example, in the field of printing plate making, streamlining of work processes,
2. Description of the Related Art Image scanning, reading and reproducing systems that electrically process image information carried on a document to create a film original are widely used for the purpose of improving image quality.

An image scanning reading and reproducing system basically consists of an image reading device and an image reproducing device.

In this case, the image reading device illuminates the document being conveyed in the sub-scanning direction in the main scanning direction using illumination means, and the image reading means reads the reflected light or transmitted light and converts it into an electrical signal. On the other hand, the image reproducing device performs arithmetic processing such as gradation correction and edge enhancement according to plate-making conditions on the image information photoelectrically converted by the image reading device, and records and reproduces the image on a record carrier such as film. Note that this recording carrier is developed by a predetermined developing device and used as a film original for printing or the like.

Generally, in this type of image reading device, when a transmissive original such as a film or a reflective original such as a printed matter is transported in the sub-scanning direction, the original is placed on a document table that is movable in the sub-scanning direction. At the same time, the document is positioned and held on the document table by a placing table made of a transparent plate.

Here, the work of attaching and removing the document to the document table is actually performed outside the image reading device, and the casing that constitutes the image reading device has an opening for passing the document table. It is defined.

At this time, the dimensions of the opening and the document table are matched as much as possible to prevent dust, external light, etc. from entering the housing from the outside.

On the other hand, inside the housing, illumination means is arranged as close as possible to the document table in order to efficiently irradiate the document with illumination light. Therefore, the mounting table for holding the original is selected to be quite thin, and the handle itself, which the operator holds when moving the document mounting table, is located on the side of the mounting table and close to the original table. It is necessary to provide

That is, to explain this using FIG. 1, an opening 2 is defined in a housing 1 constituting the image reading device.
A document table 3 is configured to be freely movable between the inside and outside of the housing 1 via this opening 2. A read original 4 is placed on the original table 3, and this read original 4 is placed on the placing table 5.
The document is held against the document table 3 by. Handles 6a and 6b are fixedly attached to both sides of the mounting table 5, respectively, and the operator handles the mounting table 5 by gripping these handles 6a and 6b.

However, as described above, since the handles 6a and 6b are provided close to the document table 3 side, it is difficult for the operator's fingers 7 to enter between the handles 6a, 6b and the upper surface of the document table 3. It has been pointed out that there is an inconvenience in that it is difficult to hold the mounting table 5. Moreover, the handles 6a and 6b
When attempting to place the mounting table 5 on the document 4 by gripping it, there is a high risk that the mounting table 5 will fall because it is difficult to grip the respective handles 6a and 6b. This exposes the disadvantage that the handling of the mounting table 5 is extremely poor.

Note that if the handles 6a and 6b are configured to be long and inclined in the direction away from the document table 3, as shown by the two-dot chain line in FIG. Although this is easy, problems such as the handles 6a and 6b coming into contact with the outer wall of the housing 1 or interfering with illumination means (not shown) occur when the document table 3 is conveyed in the direction of the arrow.

The position of the holding member 134b is selected so that the illumination angle α formed with the virtual perpendicular P perpendicular to is about 15°. Reflected illumination light L2 collected by the rod lens 140
reflects the reflective original S2 and then enters the CCD camera 110 via the mirror 108. At this time, the CCD camera 110 is disposed at a position where it can read the reflected illumination light L2 reflected at a reading angle β of about 30° with respect to the virtual perpendicular P via the mirror 108.

The image reading device according to this embodiment is basically configured as described above, and its operation and effects will be explained next.

First, when reading the transmission original SI, the presser cover 58 of the document table 32 is closed, the pin members 67a and 67b are fitted into the holes 80a180b of the frame 77, and the frame 77 is moved to the base 5.
Fixed at 4. Next, the mask member 6 is placed on the holding glass 78 through the pin member 67a167b and the holes 86a and 86b.
0 is placed thereon, and a transmission original SI is placed in the opening 84 formed in this mask member 60.

Therefore, the mounting table 10 is placed on the mask member 60 by gripping the gripping parts 20a and 20b that constitute the handles 16a and 16b of the mounting table 10, and the presser glass 12 and the presser lid 58 are placed on the mask member 60.
The transmission original S is held between the holding glass 78 and the holding glass 78 .

Then, the document table 32 is conveyed in the direction of arrow A under the action of the drive motor 52 and moved to a predetermined portion of the image reading section 36 .

The document table 32 holding the transparent document S1 is connected to the image reading unit 36.
When reaching a predetermined portion of the transmissive original Sl, an operation of reading the image information carried by the transmissive original Sl is started. That is, the transmitted illumination light L+ outputted from the light source 98 passes through the optical fiber bundle 102, is condensed by the rod lens 104, is reflected by the hairline mirror 106 at a predetermined angle tilted with respect to the vertical upward direction, and is reflected by the opening 96. The document is then guided to the document table 32. Further, the transmitted illumination light is applied to the transmission type original S1 through the base glass 56 and the presser glass 78 in the direction of arrow C shown in FIG. 4, that is, in the main scanning direction. In this case, the transmitted illumination light L1 is the transmitted illumination light L1.
image information is extracted as an optical signal. After the image information as an optical signal passes through the holding glass 12 of the mounting table 10, it is reflected in the horizontal direction by the mirror 108 and enters the CCD camera 110.
It is converted into an electrical signal within 0. During this time, the document table 32 is being transported in the sub-scanning direction (in the direction of the six arrows) under the action of the drive motor 52. Therefore, the transmission type original S1 is illuminated two-dimensionally by the transmission illumination light, and its image information is extracted. After the reading operation is completed, the drive motor 52 is rotated in the opposite direction to move the document table 32 to a predetermined position.

Next, when reading the reflective original S2, first,
The mounting table 10 is removed from the base 54 via the handles 16a and 16b, and the transmission original S1 and mask member 60 are removed from the presser glass 78. Next, with the presser lid 58 open, the reflective original S2 is placed facing upward on the base glass 56, and then the presser lid 58 is closed and the bottle members are inserted into the holes aoa and aob of the presser lid 58. 67a, 67

When the document table 32 reaches a predetermined part of the image reading section 360,
The reading operation of the reflective original S2 is started.

That is, the reflected illumination light L2 output from the light source 132 passes through the optical fiber bundle 138, is focused by the rod lens 140, and is guided to the document table 32. Then, the reflected illumination light L2 irradiates the reflective original S2 in the main scanning direction through the presser glass 78, and image information is extracted as an optical signal. This image information as an optical signal is transmitted to the presser glass 7.
After reflecting 8 in an oblique direction, CC
The signal is guided to the D camera 110 and converted into an electrical signal.

During this time, the document table 32 is being transported in the sub-scanning direction under the action of the drive motor 52, so the reflective document S2 is two-dimensionally scanned by the reflected illumination light L2, and its image information is extracted. Become.
