An automatic document feeder for an electrophotographic copying machine comprises a plurality of document trays each for piling a plurality of documents thereon, a plurality of document exhaust trays each for receiving the documents, document exhaust rollers rotating to transport the documents into one of the plurality of document exhaust trays, and a switching gate for selecting the way of transporting the documents into anyone of the plurality of document exhaust trays. A document transport belt is provided for transporting the documents. The document exhaust rollers and the document transport belt can be driven in bidirectional directions.
摘要:
In a copying machine in which a plurality of copies are made on a plurality of sheets of copy paper transferred from one or more paper cassettes, there are provided means for detecting the amount of the copy paper present in paper storing means, designating means for designating the number of paper to be copied, means for judging whether the amount of the copy paper present in said paper storing means exceeds the number of the copy paper designated by said designating means in a period after said paper storing means is set in the copying machine and before beginning of transferring of the copy paper to paper process means and means for alarming that the sheet number of the copy paper is more than the amount of the paper present in said paper storing means.
摘要:
A copying machine which can stop or interrupt a copying operation of reserved originals even when it is still in the middle of a copying operation so as to permit the copying of un-reserved originals. The interruption takes place when a human body sensor detects a person coming up to the copying machine, or when a timer counts up a predetermined time. Also, the copying machine has a first counter which counts a first predetermined time after the end of the copying operation. If no copying operation is performed during the first predetermined time, a second counter starts to count a second predetermined time immediately after the first predetermined time. During the counting of the second predetermined time, a copy start button is made invalid. When the second predetermined time is counted, the reserved copying operation starts.
摘要:
An automatic document feeder, made a part of a two-side copying machine which selectably operates in one-side or two-side copying mode of operation, has a pre-feeder which advances a document to be copied next from its original position to a waiting position before reaching a copying position on a document table. A selecting device is further included for controlling the pre-feeder such that the pre-feeder does not function when the second surface of a document is being copied in two-side copying mode of operation.
摘要:
A copying machine for copying an original in the form of a double-spread page placed on an original stand or carriage such that the original is accurately divided when copied onto two sheets of paper. The copying machine includes a control device for controlling a copy start position of an original copy operation by a time difference determined between a reference position timing of an original scanning and a sheet feed start timing, and is operable regardless of a selected magnification.
摘要:
An automatic duplex electrophotographic copying machine having a single side copying-related transport passage communicating from a paper supply section through a copying process section to a discharge outlet, a duplex copying-related transport passage located under the single side copying-related transport passage and communicating from the vicinity of the discharge outlet to the vicinity of the paper supply section, an intermediate tray provided in the approximate center of the duplex copying-related transport passage, and a plurality of bins mounted at the discharge outlet to store discharged copy papers, comprises a detector provided at the paper supplying side of the intermediate tray of the duplex copying-related transport passage to detect the picture image density on a copy paper; and a storage bin selection unit for delivering a defective copy paper to a particular bin among the plurality of bins when the detector does not detect any picture image on the copy paper while the copy paper is passing the position of the detector.
摘要:
An electrophotographic copying machine includes a device for detecting the size of a copy document on a document table. The device has at least two light receiving elements directed to detect, in combination, a single size of the copy document. The two light receiving elements are responsive to the size of the copy document for outputting two document size signals. The document size signals have the same signal levels when the two light receiving elements are both prevented from receiving light by the document, or different signal levels when either of the light receiving elements is prevented from receiving light by the document. The copying machine comprises a detection circuit responsive to the document size signals for calculating the possible difference of the document size signal levels and detecting the particular size of the copy document.
摘要:
An image processing device includes a scanner, which reads a plurality of images and inputs them as multivalue digital image data; a matching data producing section which, based on the inputted multivalue image data, produces matching data for joining the respective inputted images; a post-processing section, which binarizes the image data of each image inputted by the scanner; a joining section, which synthesizes the respective inputted images into a single image by joining the binary data produced by the post-processing section, which corresponds to the image data of the respective inputted images, on the basis of the matching data produced by the matching data producing section; and a printer for outputting the image joined by the joining section. Thus an image processing device can be provided which is capable of joining any type of image, whether from written characters, halftone dot, or photographic originals, and of performing this joining processing at high speed.
摘要:
A document feeder includes: a document detecting device arranged on the top of the copier body, for detecting a document inserted from the outside; a feed roller arranged adjacent to the document detecting device, on the top of the copier body, for feeding an inserted document into a space between the original table and the original cover, in response to the detection of a document by the document detecting device; and an original cover lifting device arranged on the top of the copier body, for lifting the original cover to create a gap between the original table and the original cover, in response to the detection of a document by the document detecting device. Alternatively, the feed roller further has a rotary cam on its shaft, so that the cam rotates to lift the original cover up as the feed roller rotates in the document feeding direction. Then, after the document is fed in place, the feed roller is reversely rotated in a constant time, whereby the document cover is sunk to press the document onto the original table.
