Abstract

PURPOSE:To easily synthesize plural images by reading the images via an image reading device which can read plural images at one time and synthesizing these read images at one time via an image synthesizing device. CONSTITUTION:The illumination lamps 12 and 22 simultaneously illuminate the originals 10 and 20 respectively. The reflected light of the lamp 12 forms an image on a photodetector array 17 via a mirror 13, the reflecting mirrors 14 and 15 arranged opposite to each other at 90 deg., and a lens 16. Meanwhile the reflected light of the lamp 22 forms an image on the array 17 via a mirror 23, the reflecting mirrors 24 and 25 arranged opposite to each other at 90 deg., and a lens 26 respectively. The originals 10 and 20 are scanned when the lamps 12 and 22 and the mirrors 13-15 and 23-25 are scanned toward arrows at a 2:1 speed, for example, at one time and at the same speed. Then each reflected light forms an image at the same position of the array 17 with control of angles of those mirror 13-15 and 23-25 respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an image reading device that projects an image of a document and reads it with an image reading means.

2. Description of the Related Art Conventionally, as this type of device, for example, the one shown in FIG. 2 is known.

In the conventional example shown in FIG. 2, when reading an image on a document, the document is placed with the image side facing down on the document table glass 31.
The illumination lamp 32 illuminates the document 30, and the reflected light passes through a mirror 33, reflective mirrors 34 and 35 arranged at an angle of 90' to each other, and a lens 36 to a light receiving element array. The image is formed on 27. The document is scanned by scanning the illumination lamp 32, mirror 33, and reflection mirrors 34, 35 at a speed of 2:1 in the direction of the arrow.

Problems to be Solved by the Invention The conventional image reading apparatus described above reads only the original one sheet at a time, and therefore cannot simultaneously read images other than the original.

The present invention has been made in view of the above-mentioned conventional situation,
Accordingly, an object of the present invention is to provide a novel image reading device that is capable of simultaneously reading and composing a plurality of images.

Means for Solving the Problems In order to achieve the above object, an image reading apparatus according to the present invention includes an image reading means for simultaneously reading a plurality of images, and an image reading means for simultaneously combining the plurality of images read by the image reading means. and composition means.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a schematic diagram showing an embodiment of the present invention.

Referring to FIG. 1, when reading a document, place the image side down on the document table glasses 11 and 21 [Documents 10 and 2].
Set 0.

Here, the illumination lamps 12 and 22 are connected to the originals 10 and 2.
0 are illuminated at the same time, and the light reflected by the illumination lamp 12 passes through the mirror 13, the reflecting mirrors 14 and 15 arranged at an angle of 90 degrees to each other, and the lens 16, and the light reflected by the illumination lamp 22. are mirrors 23, each other 9
a reflective mirror 24.25 arranged with an angle of 0°;
The images are then simultaneously formed on the light receiving element array 17 via the lens 26.

Further, the scanning of the originals 10 and 20 is carried out simultaneously at the same speed using the illumination lamp 12, mirror 13 and reflection mirror 1415, respectively.
and illumination lamp 22, mirror 23 and reflective mirror 242
5 in the direction of the arrow at a speed of 2:1.

In addition, each reflected light is reflected by the mirror 13 and the reflecting mirror 1415.
By adjusting the angles of the mirror 23 and the reflecting mirrors 24 and 25, the image is formed at the same position on the light receiving element array 17.

In the present invention, the original platen glass is divided into 11 and 21, but it can be easily inferred that the same operation can be achieved by integrating these glass plates and fixing a plurality of original platens 1 as an alternative.

As described in detail, according to the present invention, by having a means for simultaneously reading a plurality of images and composing the plurality of images, it is possible to obtain the effect of easily composing the plurality of images.
