Filed: 1992-07-28
Abstract: PURPOSE:To obtain the sufficient removing efficiency of excess developer without causing irregularities in a toner image by providing a nozzle blowing off air in the vicinity of the downstream side of a developing electrode. CONSTITUTION:Since a gap formed by the opposed surface 3e of the developing electrode 3 and the outer peripheral surface of a rotating drum 1 is successively supplied and filled with the developer, an electrostatic latent image on photosensitive paper 9 which reaches the gap is developed and becomes a visible image. When the photosensitive paper 9 at a part where the electrostatic latent image is developed comes off from the opposed surface 3e of the electrode 3 by the rotation of the drum 1 and passes the side surface 3d on the downstream side of the electrode 3, the developer sticking and remaining on the surface is pressed back to the side surface 3d by air flow blown off from the nozzle 5a of an excess developer removing device 5, and flows down with the air flow falling along the side surface 3d, and is recovered in a developer recovery drain 4. Thus, the excess developer is recovered with high removing efficiency without causing the irregularities of the toner image.

Abstract: PURPOSE:To execute an internal state value to be allocated to a network structure part at much higher speed by variably setting the value of a learning constant corresponding to the advancement of learning while guaranteeing the sureness of converging the learning of the internal state value for the learning constant. CONSTITUTION:When an error value calculated by an error value calculation part 29 is smaller than a prescribed value, it is detected that learning is advanced.

When detecting the error value of this time learning cycle is increased rather than the error value of the preceding learning cycle, the value of the learning constant at the presentation processing part 27 is decreased for the prescribed value. Thus, the internal state value to be allocated to the network structure part can be decided at high speed.
