摘要:
A developer agitating/conveying device having at least one partition wall disposed within a housing with a developer transfer port at the central portion thereof; a first agitating/conveying member disposed along the partition wall on one side of the partition wall for conveying the developer from the opposite end portions toward the central portion thereof, the first agitating/conveying member having a first helical blade and a second helical blade; and a second agitating/conveying member disposed along the partition wall on the other side of the partition wall for conveying the developer from the central portion toward the opposite end portions thereof, the second agitating/conveying member having a first helical blade and a second helical blade. The first and second helical blades provided on the first agitating/conveying member for helically wound in directions opposite to each other and are constructed such that their respective inner end half pitches overlap with a phase angle of 180 degrees relative to each other so as not to intersect each other.

A latent electrostatic image developing device using a developer including a toner and carrier particles has a development housing, in which an upstream agitating/conveying device, a midstream agitating/conveying device, and a downstream agitating/conveying device are disposed. The upstream agitating/conveying device conveys the developer from the central portion in the widthwise direction toward the opposite end portions in the widthwise direction while agitating it, the midstream agitating/conveying device conveys the developer from the opposite end portions in the widthwise direction toward the central portion in the widthwise direction while agitating it, and the downstream agitating/conveying device conveys the developer from the central portion in the widthwise direction toward the opposite end portions in the widthwise direction while agitating it.
摘要:
An image forming machine including a host computer, a printer, a copying machine, and a document supply device for conveying a document printed by the printer to a document stand of an automatic document feeder of the copying machine is disclosed, the image forming machine including a first document conveying device for directly conveying the document printed by the printer to the automatic document feeder, and second document conveying device which has an intermediate tray for temporarily storing the document printed by the printer for conveying this document to the automatic document feeder after temporarily storing it in the intermediate tray.
摘要:
An image forming machine including a host computer, a printer, a copying machine, and a document supply device for conveying a document printed by the printer to an automatic document feeder of the copying machine, in which a controller is provided for controlling a copy action based on a copy command from the host computer. The controller sends a left-behind document signal when a document is present on document stand of the automatic document feeder, while the host computer shows the presence of the left-behind document on a display when receiving the left-behind document signal from the controller.
摘要:
An image forming machine includes a host computer, a printer, a copying machine, and a document supply device for conveying a document printed by the printer to an automatic document feeder of the copying machine. The host computer and a control device provided in the printer are connected together via a parallel data transfer type interface, while the host computer and control device provided in the copying machine are connected together via a serial data transfer type interface. Thus independent data are transferred from the host computer to the control device of the printer and the control device of the copying machine.
