Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a document reading device in which a document reading section and a received image recording section are arranged in two stages, upper and lower.

In general, in facsimile devices that use a document reading device, it is possible to make the device smaller and simpler by devising the arrangement of the document reading section and the received image recording section. It has been proposed that the reading section and the received image recording section are arranged in two stages, upper and lower. In this case, the means for attaching each member of the document reading section is that a plurality of main body stays are fixed between both side plates of the main body, and the members are attached via these main body stays. Therefore, a main body stay is required to attach the document reading section, which increases the number of parts and increases costs.
This results in an increase in size.

The present invention has been made in view of these points, and it is possible to use a part of the document reading section to attach and support other components without hindering the strength of the document, thereby making the document more compact and simple. The purpose is to obtain a reading device.

The present invention utilizes a scanner base that forms the optical path for the optical system of the document reading section and uses it as a main body stay, and is configured so that it can be made more compact by attaching other members to the scanner base. It is.

An embodiment of the present invention will be described based on the drawings.
First, FIG. 1 schematically shows a facsimile apparatus using a document reading device, in which a document reading section 1 and a received image recording section 2 are arranged in two stages, upper and lower. The document reading section 1 is provided with a document mounting table 4 on which a plurality of documents 3 can be set. A document separation and conveyance mechanism is provided in front of the document placement table 4. That is, when the original 3 is set in this mechanism, the original transport rollers 5 and 6 are rotated by a driving source (not shown), and the original 3 is sent to the left. Since they are in pressure contact, the originals 3 are sent in a stacked state, and the upper original 3 is pressed down by the presser plate 7, and is separated from the lower one and sent out one by one. Also, a transport roller 8 that transports the original 3 sent out from the original transport roller 6 to a reading position.
is provided. A light source 9 that irradiates illumination light onto the original 3 at this reading position is provided, and an optical system 14 such as a target glass 11, a mirror 12, and a condensing lens system 13 that forms a reflected image on an image sensor 10 is provided. It is set. here,
The image information read by the image sensor 10 is subjected to processing such as binarization and data compression before being sent to the receiving side, and the conveyance roller 8 operates intermittently in accordance with the processing speed at this time. . and,
A conveyance roller 16 is provided that discharges the document 3 that has passed the reading position toward the tray 15.

On the other hand, in the received image recording section 2, a recording paper 17 is set in a holder 18, and this recording paper 17 is pulled out by a platen roller 20 via a guide roller 19, and a recording head 21 that is in opposing contact with this platen roller 20 is pulled out. After recording the received image information, the cutter 22 cuts the received image information, and the paper ejection roller 23
The paper is configured to be discharged onto a tray 24 by means of the following. Here, the received image recording section 2 is formed into a unit, and can be freely pulled out to the left in the figure by means of a rail mechanism or the like on both sides of the bottom plate 25 of the facsimile apparatus.

In the document reading section 1, the optical system 14 is set vertically up to the mirror 12, and the part from this mirror 12 to the image sensor 10 is set horizontally in the front-rear direction. A scanner base 27 is provided which forms a closed optical path 26 . This scanner base 27 is made by die-casting, and consists of a lower member 28 and an upper member 29 fixed with screws 30.
It is formed into a convergent shape when viewed in plan in accordance with the convergence of the optical system 14 from the mirror 12 to the lens system 13. The rear end side of the lower member 28 is lowered one step to attach the lens system 13 and the image sensor 10 to the mounting part 3.
1, and a cover 32 covering these is attached with screws 33. In addition, the lower member 28
Attachment portions 34 inclined at 45 degrees for attaching the mirror 12 are formed on both sides of the front end side. The scanner base 27 is fixed to both side plates 35 and 36 of the main body for the document reading section 1, and mounting arms 37 as a plurality of mounting portions extend from both sides of the lower member 28 in the left and right direction. ing. These mounting arms 37
It is formed into a substantially trapezoidal shape so that the width becomes narrower from the base side toward the tip, and the tip has a screw hole 39 corresponding to the screw hole 38 of the side plates 35 and 36.
is formed so that it can be fixed with a screw 40. Furthermore, ribs 41 that function as reinforcing ribs are formed on the lower surfaces of these mounting arms 37. Further, the mounting portion 34 can also be fixed to the side plates 35 and 36 with screws 40. A mounting rib 42 is formed on the upper surface side of the mounting arm 37 at a slightly higher height and has the same height, and a screw hole 43 is formed therein.

Therefore, the lower member 28 and the upper member 29 are fixed with screws 30 to form the scanner base 27,
After this is fixed to both side plates 35 and 36 with screws 40, the both side plates 35 and 36 are fixed to the bottom plate 25 with screws 44, thereby completing the assembly of the casing system. In this state, the scanner base 27 functions as a stay and fixes the positional relationship between the side plates 35 and 36. At this time, scanner base 2
7, the optical path 26 forming portion and the mounting arm 37 have a substantially trapezoidal shape (converging shape) when viewed in plan, and the mounting arm 37 is provided with a rib 41, so that it has sufficient strength. become. Therefore, other members such as the control circuit member 45 in the document reading section 1 can be directly mounted with the screws 46 using the mounting ribs 42 of the scanner base 27, and a stay for the mounting is not required. be able to. Furthermore, after the lens system 13 and the image sensor 10 are attached to the attachment portion 31, they are covered with a cover 32.

As described above, in the present invention, a mounting part with reinforcing ribs is formed on the scanner base that forms the optical path for the optical system of the document reading part, and is fixed to both sides of the main body. This scanner base itself can be used as a stay, and other parts of the document reading section can be attached to this scanner base without providing a dedicated stay, making it more compact. The device can be simplified and simplified.
