The base plate 32 is mounted freely slidably on a rail 36 laid on the bottom part of the dark box 31, and supported by an endless member 38 extended between two shafts 37 and 37' to move at right angles to an optical axis by the forward/backward rotation of a driving motor 39 through a warm 40 and a gear 41. Therefore, the lens 27 or 33 is moved selectively onto the exposure hole 30.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image recording/copying apparatus having an image input panel function and a copying function.

Conventionally, this loincloth image recording/copying device 6 is as shown in the first diagram.
A light beam from a light source 3 is applied to the document surface 2 on the document table 1, and the reflected light from the document surface is split by a splitter 6 through a reflection mirror 4 and a lens 5, and one of the light beams is imaged on a photoreceptor drum 7. , the other is read by the image reading element 8, and the signal is stored in a memory (not shown) or the like or output to the semiconductor laser 9, and the laser light from the semiconductor laser 9 is transmitted to the polygon 10 and the fθ lens. 11 to scan the photosensitive drum 7. The latent image recording using the image input optical system and the latent image recording using the copying optical system are separated by a splitter 6.
It was structured so that paper and other materials were shared and could be switched and used as needed.

However, Hiko found that in the above conventional image input optical system, it is difficult to adjust the position of the lens 5 and the image reading element 8, which are installed before and after the tin ritter 60, and that it is especially difficult to switch between the image input optical system and the copying optical system. When the image reading element and the lens are moved separately, there is a problem in that the positional relationship between them is likely to be distorted, making it even more difficult to adjust the position.

This invention is intended to solve the above-mentioned problem, and includes an image input lens and an image reading element arranged in parallel on a copying lens installation substrate provided between the document surface and the photosensitive drum. Takumi decided to make it possible to switch between the copying optical system and the manual image optical system by moving the substrate.
To provide an image recording and copying island in which the positional relationship between an image input lens and an image reading element is determined in advance, and the positional relationship between them is not disturbed when switching between an image input optical system and a copying optical system. The purpose is to

Next, the present invention will be explained based on an embodiment shown in FIG. 2 and subsequent figures.

20 is a main body, 21 is a document table, and 22 is a light source that irradiates a document surface 23 on the document table 21. The reflected light from the document surface 23 irradiated by the light source 22 is reflected by a first mirror 24 that moves together with the light source 22, a second mirror 25 fixed to the main body 20,
The light enters a copying lens 27 through a third mirror 26, and is imaged onto a photosensitive drum 29 through a fourth mirror 28.

The copying lens 27 has an exposure hole 3 on the front as shown in the third figure.
It is installed on a substrate 32 provided in a dark box 31 having 0. Reference numeral 33 denotes an image input lens disposed on the installation board 32 of the copying lens 27;
An image reading element 35 is attached to a wall plate 34 erected on the substrate 32 immediately behind the.

The board 32 is slidably mounted on a rail 36 laid at the bottom of the dark box 31, and is mounted on two shafts 37,
The worm 40. It is configured to be movable via a worm gear 41 in a direction substantially perpendicular to the optical axis.

In addition, 42 in the figure is an operation switch of the image reading element 35;
3 is an activation switch for the copying optical system.

In FIG. 3, the image input lens 33 is connected to the exposure hole 30 of the dark box 31.
When facing the document surface 23, the reflected light from the document surface 23 is
The light enters an image input lens 33. The light beam that enters the image input lens 33 is read by an image reading element 35 placed immediately behind it, and the signal is stored in a memory (not shown) or the like, or is stored in a second
The laser light emitted from the semiconductor laser 44 is outputted to the semiconductor laser 44 shown in the figure. Gon 45. ．．
The light is scanned onto the photosensitive drum 29 via the iθ lens 46.

47 is a dark box 3 facing the mirror surface of the mirror 28;
A four-light slit provided at the bottom of the copying lens 2
The light beam passing through 7 is reflected by the fourth mirror 28 and reaches the photosensitive drum 29 through this exposure slit 47.

Note that a latent image recording section for development, transfer, etc. is arranged around the photosensitive drum 29, so that image recording is performed.

4A and 4B are explanatory diagrams showing the operation of the present invention, and FIG. 4A shows the case where reflected light from the document surface 23 passes through the copying lens 27 and forms an image on the surface of the photoreceptor drum 29. There is. In this case, the image input lens 33 and the image reading element 35 are located at a position away from the exposure hole 30 on the front side of the dark box 31, and do not function at all. In the same figure, B is the board 3.
2 is moved to align the image input lens 33 with the exposure hole 30 of the dark box 31, and the reflected light from the document surface 23 is incident on the image input lens 33.

As described above, the present invention provides an image input lens and an image reading element in parallel on a copying lens installation substrate provided between the document surface and the photoreceptor drum, and by moving the substrate. Since the optical system for copying and the optical system for image input can be switched, when recording an image, the reflected light from the document surface is passed through the copying lens to form an image on the photoreceptor drum. It is possible to selectively and easily process the multi-signal processing by an image reading element through an input lens and store it in a memory, or output it to a semiconductor laser and scan it onto a photoreceptor drum through a polygon or fθ lens. Further, the image input lens is provided separately from the copying lens, and the image reading element is positioned in advance with respect to the image input lens, and this positional relationship is determined between the copying optical system and the image input optical system. Each f81i has an excellent effect of not going out of order even when switching.
