摘要： A sheet feeding device, includes a lift down sensor for detecting a rotating plate of a rotatable cassette lowered down to a planar position, a lift up sensor for detecting the rotating plate lifted up to a sheet feeding position, a lateral feed position detecting sensor for detecting the rotatable cassette situated in the lateral feeding position, a longitudinal feed position detecting sensor for detecting the rotatable cassette situated in the longitudinal feeding position, and control means for controlling the drive mechanisms of the sheet feeding device. In the rotating operation of the rotatable cassette, if the lift down sensor is not turned on, the rotating plate is lowered so as to turn on the lift down sensor, thereafter the rotatable cassette is rotated to the predetermined longitudinal or lateral feeding position, and after the lateral or longitudinal feed position detecting sensor is turned on, the rotating plate is lifted up until the lift up sensor is turned on.

摘要： A network system for copiers includes a plurality of copiers each provided with a communication device for communicating with external equipment and a power-on device for powering on the copier in a hold state in response to an external signal received by the communication device and a main controller including an operation controller for controlling operation of the copiers and a time setter for setting time to power on a copier, the main controller being connected to the copiers by a network. The operation controller executes control such that only predetermined one of the copiers is powered on at the power-on time set by the time setter.

摘要： An image forming apparatus comprising rotatable cassettes rotated by cassette rotating means between a longitudinal feeding station from which paper is fed in a longitudinal direction thereof and a lateral feeding station from which paper is fed in a lateral direction thereof, wherein memory means stores a cassette rotation signal, when the cassette rotation signal is entered therein and cassette rotating means is controlled in accordance with the cassette rotation signal stored in the memory means when a cassette rotation permission signal for permitting the rotation of the rotatable cassette is generated, so that the rotatable cassette is set in a predetermined feeding station.The invention also provides an image forming apparatus capable of storing the feeding station of the rotatable cassette in the memory means and rotating the rotatable cassette to the feeding station stored in the memory means when the rotatable cassette is out of both longitudinal feeding station and lateral feeding station. Further, the invention provides an imagae forming apparatus capable of selecting a desired cassette from a plurality of cassettes and instructing to rotate the rotatable cassette by depressing a minimum number of operation keys. The invention further provides an image forming apparatus wherein the rotatable cassette is taken out therefrom by setting the rotatable cassette in either of the longitudinal feeding station and the lateral feeding station, characterized in that the rotatable cassette is set in the feeding station specified as a rotatable cassette taking-out/insertion position each time an image formation is completed.
