Abstract
Abstract Disclosed is an image data transmission apparatus which includes an image reading unit for reading the original image, and a transmission apparatus main body. The main body includes a memory for storing the image data read by the image reading unit and transmits the content of the memory. The image reading unit is detachably mounted on the transmission apparatus main body. The transmission apparatus main body is further provided with a conveying device for conveying the original in a state in which the image reading unit is mounted on the transmission apparatus main body to thereby read the original. The image reading unit may also scan the original to read an original image, in a state in which the image reading unit is dismounted from the transmission apparatus main body. Further, a sheet element made of a material of a low coefficient of friction, as opposed to the original, may be disposed at a position corresponding to the mounted state of the image reading unit on the transmission apparataus main body. Further, an image data transmission apparatus is disclosed which possesses the telephone function and copy function, and is also provided with, as desired, a facsimile function by mounting a detachable facsimile processing device in the transmission apparatus main body. Further, the operation panel may be, in order to use it as the original stacker, disposed angularly dislocatably around the axial line crossing with the original inserting direction.

An image data transmission apparatus comprising: image reading means for reading an original image, and a transmission apparatus main body, including a memory means for storing the image data read by the image reading means and transmitting the data of the memory means; said image reading means being detachably mounted on the transmission apparatus main body; said transmission apparatus main body further including conveying means for conveying the original image, when the image reading means is mounted on the transmission apparatus main body, to be read by the image reading means; said image reading means being moved relative to said original, to read the original image, when the image reading means is dismounted from the transmission apparatus main body, said image reading unit further including, rotary roller means for rotating in contact with the surface of the original from which the image is to be read, and angular dislocation detecting means for sending out a signal at every predetermined angular dislocation of the rotary roller, and for detecting the relative moving state of the image reading means and the original; and said transmission apparatus main body further including, transmission means for storing the image data read by the image reading means in the memory means in synchronism with the output of the angular dislocation detecting means, and transmitting the content of the memory means, and a sheet member made of a material which has a low coefficient of friction as compared to the original, which is disposed opposite to the rotary roller means while the image reading unit is mounted on the transmission apparatus main body.
Claim 3
Dependent Claim
105 words
An image data transmission apparatus, as claimed in claim 1, wherein the transmission apparatus main body further comprises: an operating panel, having an operating surface, having one end disposed near an original inlet of the base body through which originals to be read are converted, and being free to dislocate angularly about an axial line crossing with a direction for inserting direction on originals into the base body, wherein the operating panel is stably positioned in an original guide position and the operating surface is inclined downward toward the original inlet so as to allow for stacking of a plurality of originals to be read.
