摘要： It is a major object of the present invention to break down and level a heap-up of toner built in the hopper through dropping from the cartridge when feeding toner into the hopper and to prevent toner from leakage from the cartridge due to erroneous operation with a remarkably simple and cheap construction. Namely, the leveling member moves a plurality of number of times in line with engaging and disengaging operation of the cartridge for the hopper and opening and closing operation of the cartridge in the same direction of the shutter, thereby causing a heap-up of toner built in the hopper housing of the hopper to be effectively broken down and leveled. Furthermore, only when the shutter is in its closed status for the cartridge, the cartridge can be removed from the opening of the hopper.

摘要： A printing apparatus is provided which can prevent foreign matters such as ink adhering to the surface of the conveying belt from getting transferred to other constitutional components. When the conveying belt is rotating in one direction, the foreign matters adhering to the surface of the conveying belt is removed by the wiper. When the conveying belt rotates a predetermined distance in the opposite direction, the pinch roller, the electric charge removing roller and the electric charge supply roller that are in contact with the belt surface are disengaged from the surface of the conveying belt. The predetermined distance is set equal to a rotating distance that the conveying belt rotates until a portion of the surface of the conveying belt, which was in contact with the wiper, comes into contact with the pinch roller, the electric charge removing roller and the electric charge supply roller.

摘要： At least two sets of ion-generating means are provided to face each other through a space having an insulating sheet. The first and second surfaces of the sheet are simultaneously irradiated with monopolar ion clouds substantially opposite to each other in polarity generated from the ion-generating means. The sheet is subsequently irradiated with monopolar ion clouds reverse in polarity to that of the previously applied ion clouds, to eliminate the positive and negative charges of both the surfaces of the insulating sheet.

摘要： This invention provides a small and simple construction to drive a mechanism for maintaining a printing performance of a print head. In one preferred mode of the invention, a recovery device to maintain the printing performance of the print head has a suction pump unit, a capping unit and a wiping unit. The suction pump unit is driven through a spring clutch mechanism by an LF motor in the print sheet transport unit as a drive source. The capping unit and the wiping unit are driven by an AP motor as a drive source in a rotary dead zone set for a paper feed unit that feeds the print sheet to a transport unit. A piston pump is suited for use in a recovery operation to maintain the function of the print head.

摘要： In a supply system which includes an ink container for reserving a predetermined amount of ink to be supplied to a printing head and which is configured such that ink is intermittently supplied to the container from an ink tank, there is provided a structure that fundamentally eliminates waste of ink associated with an operation of charging the container to apply a required negative pressure to the head. An ink containing body in which a negative pressure can be generated because of its elasticity is provided in the container. After the ink containing body is expanded to introduce ink into the same by depressurizing the interior of the container, the interior of the container is pressurized to contract the ink containing body, thereby returning a predetermined amount of ink to the tank. A negative pressure is thus generated in equilibrium with an ink meniscus holding ability of the head.
