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 image data transmission apparatus, which may be used as a facsimile apparatus, includes an image data reader which is detachably connected to the main body. The reader can read image data from an original fed past the reader, or it can be detached and used to scan an original. A device exists within the apparatus, which detects the mounting or unmounting of the reader, and if it is detected to be unmounted and not being used, power will be shut off. Further, a device exists, within the apparatus, which, when the reader is detected as mounted, will print read data. Also, when the reader is detected as unmounted, read data will be stored in memory. Thus, a speedy and power efficient image data transmission apparatus has been created.

摘要： A communications system connected to a telephone network includes a facsimile machine and a telephone set. The telephone set includes a telephone for conducting voice communications over the telephone network and a telephone answering machine for automatically responding to calls received by the telephone set over the telephone network. One or more operational parameters of the answering machine are set to define how it automatically responds to calls. A switch connects either the facsimile machine or the telephone set to a telephone network. One or more operational parameters of the answering machine is initially detected and stored. A controller controls the switch to connect either the facsimile machine or the telephone set to a telephone network based on a comparison of the stored parameter(s) and subsequently detected operational parameter(s) detected when the answering machine responds to a call.

摘要： A facsimile apparatus is provided which can enhance the operability and usefulness of portable image reading devices when transmitting documents and which allows effective utilization of the image reading device. The facsimile apparatus includes a main unit and a separable handscanner between which image signals and various control signals are transmitted using an optical communication technique. A document is scanned by a handscanner that generates signals representing the document image. The image signals are temporarily stored in an image memory and transmitted to the main unit when necessary. Depending on the hook state of the telephone, the main unit either transmits the received image signals to a remote station or records the image on recording paper. When the main unit receives image signals over a telephone network, the received image signals are transmitted to the handscanner for storage into the image memory when necessary. This is done for example, when the so-called memory reception mode is set or when a recording section in the main unit is in a non-normal state.

摘要： A facsimile communication apparatus is disclosed which is operable under either one of a facsimile mode for transmitting facsimile signal from a calling station along a telephone line to a called station, and a conversation mode for sending conversation signal from the calling station along the telephone line to the called station. The facsimile communication apparatus at the called station includes a detector for detecting a facsimile request signal indicative of a facsimile communication request made by a calling station within a predetermined period of time after a telephone line is connected to a facsimile communication apparatus of the calling station, and a signal producer for producing a facsimile request signal when the detector detects the facsimile request signal and for producing a conversation request signal when the detecting means detects no facsimile request signal within the predetermined period of time.

摘要： A group III facsimile apparatus is provided with a detachable image reading unit for hand held scanning of large or bulky originals. Lines of image data from the image reading unit are stored in a memory, and then read out and converted to modified Huffman (MH) running length code for transmission. Fill bits are added where necessary so that each line has a minimum transmission time of 10 milliseconds. A group III facsimile apparatus normally automatically disconnects from a transmission when no data has been transmitted for five seconds. To keep this from happening while an original is being scanned slowly by hand, enough fill bits are added to make each line a minimum transmission time of one second when the number of lines of image data in the memory is less than 10.

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： 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.
