摘要： Near a discharge device (48) for discharging paper (P) with an image formed thereon, there is provided a punch (7) for punching holes. The drive of the discharge device (48) is controlled so that the punch punches the punch holes in the trailing portion of the paper (P), without causing creasing or tearing or change in the quality of the paper (P). The punch (7) includes punching cutters (72) and a punching die (74). The punching cutters (72) and the punching die (74) are provided in a unit (U) which can be drawn out of a casing (1) covering the punch (7). With the unit (U) drawn out of the casing (1), jam recovery can be easily executed. The unit (U) is movable in the width direction of the paper (P), thereby making it possible to adjust the position of punched holes. A collecting box (76) for collecting paper scraps (P1) is disposed in the unit (U). If the collecting box (76) is pivoted or the opening (76a) thereof is lifted up when the unit (U) is pivoted, the paper scraps (P1) therein will not fall out. Delaying timing for plural punching cutters (72) to punch holes can reduce the load on the drive system.

摘要： A paper guiding device in a copying apparatus includes, in opposition, a lower guide plate having a main flat portion and an upper guide plate having a main flat portion. A plurality of rising pieces, having top edges and being laterally spaced apart upon the upper side of the main flat portion of the lower guide plate, rise above the lower guide plate and extend in the direction of movement of the copying paper. A plurality of hanging pieces, having lower edges and are laterally spaced apart on the lower side of the main flat portion of the lower guide plate, hang from the upper guide plate and extend in the direction of movement of the copying paper. The top edges and the lower edges define a path of movement of the copying paper while having minimal contact with the paper. A plurality of openings through the upper guide plate and an opening through each of the hanging pieces dissipate heat from the copying paper to substantially prevent the accumulation of moisture on the copying paper and in the improved paper guiding device.

摘要： A transfer type electrostatic copying apparatus in which the area of a photosensitive member cleaned by a cleaning device reaches an exposure zone simultaneously or prior to the arrival of a movable portion of an optical system or an original carrier at an exposure starting position from a home position thereof. This results in clear and definite copied images being obtained. At the earlier stage at which the movable portion of the optical system or the original carrier starts moving, the photosensitive member is subjected to the cleaning process, and then the exposure process is effected when the movable portion or the original carrier is running stably. Thus, the electrostatic latent image obtained by the exposure are clear and definite and free from undesirable blurs. The photosensitive member is a rotary drum having bosses connected at opposite axial ends thereof which are removably mounted in holder members on the sidewalls of the copying apparatus. A conical-shaped shaft which rotatably supports the drum has a threaded portion thereon which cooperates with a threaded portion in one of the bosses to secure the shaft to the bosses.

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 copying paper is deflected at least twice in the conveying process thereof from a paper feeding means to a photoreceptor which is disposed in the lower reaches of the conveying direction, whereby the positional state of the top edge of the copying paper is corrected at least twice. Since the extent of each deflection of the copying paper can be reduced, a habit of creasing, which has been a bad influence upon the transferring process, is not inflicted on the copying paper. The correction of the position of the top of the copying paper can be accurately carried out, whereby a clear image can be formed on the appointed position of the copying paper.

摘要： A method for controlling a copying machine having a copying cycle and fusing device. The fusing device is formed of a rotatable heating roller and a press roller in mutually forcible contact with the heating roller, which fuses a toner image on a copying paper at a fusing temperature upon passage through the rollers. The heating roller is heated to a first temperature above the fusing temperature. The copying cycle is delayed during a first interval of time after the heating roller reaches the first temperature. The copying cycle is set to a wait-reset state after the first time interval. The heating roller is cooled to a second temperature below the fusing temperature and the copying cycle is set to a wait state. The heating roller is heated from the second temperature to the fusing temperature during a second interval of time. The copying cycle is restored to the wait-reset state during the second time interval before the heating roller reaches the fusing temperature. The copying cycle is restored to the wait-reset state before a leading edge of the copying paper reaches the fusing device. In addition, the fusing device is at the fusing temperature when the leading edge passes between the rollers.

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.
