摘要： A facsimile device is composed of three separate units which are connected rotatably with respect to one another. A passageway for recording sheets is formed between the first and second units and can be opened and closed by rotating the second unit with respect to the first unit. Another passageway for an original document is formed between the second and third units and can be opened and closed by rotating the third unit with respect to the second unit. With the device thus structured, a jammed original as well as a jammed recording sheet can be removed quickly from the device.

摘要： 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.

摘要： In a facsimile circuit monitor system, a control signal to be transmitted or received is initially converted into an easily stored code to be stored in a memory. When a certain signal has been received, a signal level is calculated on the basis of actual gain of an AGC (automatic gain control) and stored in the memory so that information stored in the memory may be outputted.

摘要： An automatic sheet feeder comprises a feed roller which feeds sheets stacked in a pile one by one to a sheet conveying path, a conveyor roller provided on the sheet conveying path to convey the sheet delivered to the sheet conveying path by the feed roller to an image reading unit. The sheet conveying speed of the conveyor roller is higher than the sheet feeding speed of the feed roller. A feed roller gear is mounted on a feed roller shaft fixedly supporting the feed roller thereon and is interlocked with the feed roller shaft by a one-way clutch mechanism. The clutch mechanism couples the feed roller gear with the feed roller shaft to drive the feed roller for rotation by the feed roller gear until the leading edge of the sheet arrives at the nipping line of the conveyor roller. Thereafter the feed roller shaft is uncoupled from the feed roller gear so that the feed roller is rotated through the sheet by the conveyor roller after the leading edge has arrived at the nipping line of the conveyor roller. The feed roller gear and the feed roller shaft are again coupled in a fixed time after the trailing edge of the sheet has left the feed roller.

摘要： A color copier includes an exposure light source for exposing an original document with red, blue, and green light, on a photosensitive film having a substrate and an ink coating which includes ink particles of multiple colors carried on the substrate, and on which a reproduction of the original document is formed, in response to the light exposure, through a reaction of ink particles of the color which corresponds to the wavelength of the light reflected from the original document. The color copier further includes a lightproof film case for storing the photosensitive film, an image forming lens for forming an image of the original document on the photosensitive film by focusing the reflected light; a copy paper feeder for feeding a copy paper; a fixer for fixing the image formed on the photosensitive film on the copy paper; and a separation claw which separates the photosensitive film from the copy paper after the fixing of the image.
