Title: Developer container
Inventor: TAKEDA MAKOTO
IPC: G01F23/00
Filed: 1984-12-20
Abstract: PURPOSE:To detect the rest of toner definitely during supplementation by providing an elastic member which operates in such a direction that a developer is discharged from an opening part and detecting the rest of an internal developer from the operation position of the elastic member. CONSTITUTION:The developer container 3 which is full of toner T is mounted on a developer hopper 1 and then a lid covering the opening part 4a is detached. Then the pressurized toner T in the elastic container 5 flows out of the opening part 4a to fall and is deposited on a screw 2 for toner conveyance and sent successively to a developing device through the rotation of the screw. The elastic container 5, on the other hand, shrinks according to the outflow of the toner T, so the amount of remaining toner T is known indirectly from the height of the peak 5a of toner which is observed through a window 6. Further, the screw 2 for toner conveyance is arranged right below the opening part 4a, so a large amount of toner T does not flow out at a time and the peak part 5a moves down gradually, so the observation is easy. Consequently, the rest of the toner during supplementation is displayed by an extremely simple device with high reliability.

Filed: 1988-10-25
Abstract: PURPOSE:To prevent water from freezing and to improve operability by discharging remaining water in a hopper when an automatic operation switch is opened, and circulating the hot water in a bathtub to a circulation passage to purge the air in the passage. CONSTITUTION:A three-way valve 8 is switched to a hopper 5 side, and a pump 9 is operated to discharge remaining water in the hopper 5 to a circulation passage 7. When the facts that the float switches 51 of the hopper 5 are all OFF and the water is completely discharged are detected, the valve 8 is switched to the passage 7 side to circulate the hot water in a bathtub 6 for a predetermined period of time thereby to discharge the air sucked into the passage 7 into the bathtub 6. Even if an automatic operation switch 25 is opened to be stopped, the hot water does not remain in the hopper 5, and the passage 7 is set to the state that the water level of the bathtub 7 can be detected by a pressure sensor 12 by purging the air by the circulation of the hot water. Accordingly, when the switch 25 is closed, the water level can be initially detected, and the water level is not wastefully raised even if the hot water is already stored at the set water level or more in the bathtub 6.
