摘要:
An area setting device for setting coordinates of two points in diagonal direction of one or more number of areas by sequential key operations. Different colors are used for coordinates display (53, 53x, 53y) by each direction, the same colors as coordinates display are used for coordinates input indicator (52). Memorizing means (62, 63) memorize all the points as coordinates input condition or coordinates non-input condition, whereby the key input is accepted to the point of the highest order of all the points of coordinates non-input condition, and converted into memorized condition as the point of coordinates input condition. Then key input acceptance and memory state conversion are repeated for coordinates input of the points required.

An apparatus for regulating the movement of a movable member includes a drive device (52) for moving the movable member in a first direction from a rest position to an operative position and for moving the movable member in a second direction, opposite to the first direction, from the operative position toward the rest position. A first detector (72) detects the presence of the movable member at the rest position. A second detector (73) detects the presence of the movable member at a location adjacent the rest position but upstream thereof with respect to the second direction. A control arrangement (99) is operatively connected to the drive device (52) and to the first and second detectors (72, 73) to operate the drive device to move the movable member in the first direction and then in the second direction, to stop the drive device upon detection of the movable member moving in the second direction at the location by the second detector (73), whereafter the movable member continues movement by inertia in the second direction from such location to the rest position and is detected thereat by the first detector (72), and to, if the movable member is not detected at the rest position by the first detector (72) within a predetermined time period after the detection by the second detector (73), again starting the drive device to move the movable member in the second direction until detection thereof by the first detector (72).
摘要:
An image processing apparatus wherein a document on a document support table and an optical system are moved relative to each other for scanning to read the image of the document as a density signal, and the read signal is processed as required, the apparatus comprising a document mat so colored that when the document support table is covered with the mat, the read signal represents an intermediate color, discriminating means for judging whether the density signal represents the intermediate color to produce a binary signal, memory means having a memory capacity of 1/n based on the density signal, write control means for causing the binary signal to be written in the memory means in synchronism with the scanning movement, and means for determining the size of the document from the contents of the memory means.

57 An electrostatic copying apparatus having a semiautomatic document supplying and discharging device and a sorter in addition to its main body. The main body of the apparatus comprises a rotatable photosensitive member, means for forming a latent electrostatic image on the photosensitive member, developing means, transfer means, means for conveying a copying paper, cleaning means and a heat fixing device. In case of trouble, troubles are displayed on a display means (280) only after performing of a print signal and the copying process is inhibited.

摘要:
An automatic developing bias control device for an electrophotographic copying machine in which a document image is led onto a photoreceptor through a lens to form an electrostatic latent image on the photoreceptor and the electrostatic latent image is visualized into a toner image by a developing device, the automatic developing bias control device operating on the principle of detecting the density of the document image by means of a detecting element disposed inside or outside the optical path, delaying the output detection signal for a predetermined time, and imposing a developing bias potential corresponding to the delayed output detection signal on the developing device to thereby provide copy image quality faithful to the original.
