摘要： A copying paper feeding device comprises a first and a second paper loading sections to be loaded with a stack of copying paper sheets, a first and a second paper delivery mechanism disposed respectively in the first and second paper loading sections, a first and a second paper introducing passage extending respectively from the first and second paper loading sections and terminating in a common point of junction, a paper conveying passage extending from the point of junction, a first conveyer roller pair disposed in the first paper introducing passage, and a second conveyor roller pair disposed at the point of junction or at an upstream part of the paper conveying passage. In performing a copying process, either the first or second paper delivery mechanism is selectively actuated. The first and the second conveyor roller pairs are interlocked with each other, and adapted to be started after the first or second paper delivery mechanism has been actuated. When the first paper delivery mechanism is selectively actuated, the roller pairs are started earlier by the time required to convey a copying paper from the first conveyor roller pair to the second conveyor roller pair than when the second paper delivery mechanism is actuated. The first conveyor roller pair exerts position-correcting and synchronism-adjusting actions on a copying paper delivered from the first paper loading section, and the second conveyor roller pair exerts position-correcting and synchronism-adjusting actions on a copying paper delivered from the second paper loading section.

摘要： A detecting device for detecting when the amount of toner in a dual component developing material is less than a predetermined level includes a hopper for supplying the toner, a stirring roller for stirring a carrier and the toner from the hopper, and a detector for detecting the amount of developing material provided near the stirring roller to mix the toner supplied from the hopper with the carrier. A discriminator discriminates an output signal from the detector for a predetermined interval during the rotational period of the stirring roller. An indicating element operates in response to the output signal from the discriminator to indicate when the amount of the toner in the developing material is less than the predetermined level. Since it is indicated when the toner in the developing material is less than the predetermined level, the toner is supplied according to such indication, and therefore, an undesirable deterioration of copy density is prevented.

摘要： The present invention relates to a developing material supplying control device for an electrostatic copying apparatus which includes an oscillator circuit composed of an oscillation coil provided along a toner supplying passage, a timer, a counter for counting the output signal from the oscillation circuit at every interval predetermined by the timer to supply a discriminating output signal when the counted value is equal to a predetermined value for each of the intervals. A toner supply acts in response to the discriminating output signal from the counter for supplying toner to the toner supplying passage. Since this invention employs the oscillation coil and does not employ a mechanical switch having a movable contact for detecting toner in the toner supplying passage, the toner supplying operation is achieved precisely.
