IPC: G03G15/08
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To surely obtain high recycling rate by providing a returning path for returning recovered developer to the upstream side of a classification device on the downstream side of the classification device in the moving direction of the recovered developer. SOLUTION: A discharge port for the returning path 131 is provided in parallel with discharge ports 61 and 62 for recovered toner fed to a toner classification device 60, and the waste toner which does not pass through a mesh 68 and drops to a recovery coil 70 is returned and discharged from the discharge port 131. Namely, the waste toner dropping to the recovery coil 70 is discharged from the discharge port 131 through a flexible toner carrying pipe and returned to the device 60 again. By such constitution, the toner which is not completely classified and drops to the coil 70 is classified again, so that the good-quality toner is surely used as recycled toner without being missed and the recycling efficiency is improved.

Filed: 1982-06-14
Abstract: PURPOSE:To use a channel effectively even if the traffic of each user is varied over a wide range by observing the using status of each channel, and controlling an amount of access to each channel on the basis of the observed information. CONSTITUTION:A control circuit 7 sends provability P1-P5 from a storage circuit 8 to a comparator 11 cyclically in each slot. A ramdom number generator 10 generates a random number in each slot and sends the number to a comparator 11. The comparator 11 compares the random numbers and sends the compared result to a gate circuit 12. The gate circuit 12 is opened when ''1'' is sent from the comparator 11, and closed when ''0'' is inputted. If a backet is outputted from a slot alpha part 5 when the gate circuit 12 is opened, the backet is sent from a terminal 4 to a channel as it is, and when the gate circuit 12 is closed, the backet is once stored in a buffer 3 and waited to be sent until the gate circuit 12 is opened. An operating circuit 9 calculates values sent from the storage circuit 8 on the basis of the formula (10) and returns the calculated result to the storage circuit 8 again.
