Problems solved by technology

As a result, the productivity of the image read / write head H decreases.
[0009] Fourth, there is a possibility that the light that becomes the cause of noise may not be incident on the plurality of light receiving elements 3e
[0010] The 5th, in the image read / write dual-purpose head H of above-mentioned prior art, for example can't judge whether original document D is actually supplied to transparent cover 19e, also can't judge whether recording paper K is actually supplied to a plurality of heat generating elements 8 equally.
Therefore, such a distance setting is also troublesome.

Embodiment Construction

[0068] The preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

[0069] Figure 1~ Figure 5 An example of an image read / write head related to the present invention is shown.

[0070] As fully shown in FIGS. 1 to 3 , the image read / write head A of this embodiment is configured to include a housing 1, a sensor 2A for detecting a plurality of original documents, a sensor 2B for detecting a plurality of recording papers, and a transparent cover 19. , the lens array 5 , the light reflection preventing member 6 , the substrate 4 , the radiator plate 47 , and other components described later.

[0071] The substrate 4 is, for example, made of ceramics and is a long rectangular plate-shaped substrate. A plurality of light sources 30 , a plurality of light receiving elements 3 , a plurality of driver IC chips 80 and a plurality of heating elements 8 are mounted on the surface 4 a (upper surface) of the substr...

Abstract

An integral image reading / writing head(A)having a support means(7)capable of supporting at least one of a pair of platen rollers(P1, P2)and a detection means(2)capable of detecting at least one of an original document(D)and recording paper(K); and an image processor provided with the head(A)and produced easily due to the above constructed head. The head(A)is further provided with an antireflection member(6)surrounding collectively a plurality of photodetectors(3)and drive IC chips(80), thereby preventing, with ease, the photodetectors(3)from receiving scattered light and disturbance light.

Description

technical field [0001] The invention relates to an image read-write head with image reading function and image printing function, an image processing device equipped with the read-write head, and an image read-write head with image reading function And a print head with image printing function. Background technique [0002] A facsimile device can be given as a specific example of the image processing device. This facsimile device must have both an image reading function and an image printing function, and it is desired to be as small as possible. [0003] Therefore, it used to be as Figure 15 An image read / write head H as shown. This image read / write head H has a housing 1e with a transparent cover 19e mounted on the upper part. Inside this casing 1e are provided a light source 30e and a lens 5e for illuminating the image reading area Se on the surface of the transparent cover 19e. A substrate 4e is attached to the bottom of the housing 1e. On the front surface 40 and ...
