)を筐体(TECHNICAL FIELD This invention relates to facsimile machines. BACKGROUND ART In conventional facsimile machines, a document is illuminated by a tubular light source (such as a fluorescent lamp), and the reflected light is transmitted through a condensing lens to form an image on an image sensor. The illuminance near both edges is lower than the illuminance at the center of the document.Due to the characteristics of the condensing lens, the light that passes through the center of the lens is low.
The weight of light that passes through the periphery of the V-lens is lower than that of the lens. Due to the above reasons, the light reaching the image sensor becomes non-uniform and the reading performance is greatly reduced.In order to prevent the reading performance from deteriorating, conventional devices use a Vz-ding correction device in the darkness between the tubular light source and the document. In the conventional glue kneading correction device, however, the correction device is provided independently, so the number of parts increases by the amount of the correction device. +)Q There is also the disadvantage that a mechanism and adjustment time are required for positioning the corrector @.Disclosure of the InventionThe present invention provides an original reading section and a photoelectric device coupled to the original reading section through an optical system. A reinforcing member such as a pair of side plates installed on both sides of the housing of the facsimile machine is disposed between the converter and an optical system glue kneading correction window is provided in the reinforcing member. The reinforcing member is also used as a shading correction device, thereby omitting an independent shading correction device and adjustment time for positioning the correction device.A holding portion for a box-shaped recording roll paper is integrally molded on the reinforcing member. However, when the shading correction window is provided on the side wall of the holding section, a dedicated recording roll paper holding section is omitted and an optical axis can be formed without using the holding section as an obstacle. When the reinforcing member is integrally molded with the holding part of the condensing lens of the optical system, the shading correction window of the optical system and the holding part of the condensing lens are integrally molded with the common reinforcing member. Accordingly, the positional relationship between the shading correction window and the collective lens can be determined with high precision without the need for adjustment work. Reference numeral 1 denotes a housing of the facsimile machine, and reference numeral 21 denotes a reinforcing member that is stretched between a pair of fixed side plates (not shown) installed on both sides of the housing (1) and receives the two side plates.Reinforcing member 12) is integrally molded with resin.

) extends in the width direction [perpendicular to the drawing]. (
1) converts the direction of the optical axis of the reflected light 1 using a reflecting mirror and sends the reflected light to the photoelectric conversion section (2) described later at the rear of the floating body 1. The photoelectric conversion section (1) is located in the housing. It is arranged at the rear of the body ('') and is configured as follows.cm is a condenser lens, @ is a holding part for the condenser lens, and this reinforcing member (21 It is integrally molded with resin. (To) is a photoelectric conversion element such as an image sensor, (G) is a reading board to which the photoelectric conversion element (To) is attached, and is attached to the holding part [a] with screws (not shown). 14114 is an electric circuit board, and 12 is a cicada part. In the middle part of the reinforcing member (21) is a box-shaped recording roll paper (2). The recording roll paper d is integrally formed on the side wall (43a) of the holding part.
A shading correction window (2) of the optical system is formed at the upper part of the C. As shown in FIGS. 3 and 4, the aging correction window is narrow in the center and widened at both ends relative to the optical axis.
The upper and lower edges are arc-shaped. Therefore, the light weight of the reading light passing through the correction window (1) is suppressed at the center in the width direction, and the light (1) is hardly suppressed at both ends.
Therefore, Kounate is adjusted to Moon-. In addition, the holding part (to) of the condenser lens (B) and the shading correction window are integrally molded into a common reinforcing member (21), so that the positional relationship between the condenser lens ζm and the shading correction window can be determined with high precision without the need for adjustment work.Next, the operation of the device will be explained using a copying operation as an example.In the device, the document (4) is placed on the cover (2) on the receiving side, which also serves as a document guide. When inserted into the insertion slot along the top surface,
The first detection means [151] detects the front edge of the document (4) and generates a detection signal, and this signal activates the pulse: . (8) starts rotating.The inserted original (4) starts rotating.
) If there are a plurality of documents, they are transferred under pressure by the one-separation roller (9) and the brake piece 01, and the documents are sent out one by one starting from the lowest layer. After that, the original (4) is transferred under pressure by the paper feed roller (7) and the plate spring (11), and the front edge of the original (4) is moved to @2.
When detected by the detection means (Ie), a detection signal is generated, a timer is activated, and after -C delay time, the front end of the document (41) reaches the reading section On, and the document is temporarily stopped and lowered.Then, the document transport mechanism (3) stops feeding. The paper roller +71181 and the platen roller [&ll of the recording paper transport mechanism (I8) are rotated synchronously by pulse motors, and reading scanning and recording scanning are performed in parallel. If only one original is inserted here. , when the trailing edge of the document (4) is detected by the second detection means 00, the operation continues from the time of detection and then moves to the document ejection operation.The recording paper transport mechanism 1]8)
After the recording is completed, the recording paper (2) is conveyed to the point at which the recording ends on the recording paper (2) where it is cut by the automatic cutter, and then the automatic cutter G cuts the recording paper (2) to a predetermined length. In addition, if there are multiple sheets of the inserted document, the recording paper conveyance mechanism +116 can be used to feed the recording paper from the recording section to the cutting point every time the preceding H recording is completed. All subsequent 100 images are continuously recorded on the recording paper portion on which the images have been recorded, and the continuously recorded preceding page and subsequent page are cut and separated when passing through the cutting point, and then the final page is recorded. After finishing, what about the recording paper? The paper is fed from the recording section to the cutting point and then cut.
