摘要： PROBLEM TO BE SOLVED: To effectively make use of space inside a container by improving storing efficiency in a waste toner recovery container. SOLUTION: When a screw member 24 is rotated in a fixed direction as shown in Fig.1(a), deposited waste toner 23 is transported in the fixed direction as shown by an arrow "a". Then, the waste toner 23 is transported and packed in one end section of the recovery container 21 and a dead space 26 where no waste toner can be packed is produced on a top section on the other end section. When the screw member 24 is switched to a reverse rotational direction as shown in Fig.1(b), the packed waste toner 23 in one end section is transported in the reverse direction and the dead space 26 is made smaller. Furthermore, interval for switching the transporting direction is measured and by detecting that the recovery container 21 is made full, the space can be effectively used.

摘要： PROBLEM TO BE SOLVED: To provide an image forming device, capable of detecting whether a waste toner storage container is present or absent or whether the content thereof is nearly full or full by using only one general simply ON/OFF-detectable sensor. SOLUTION: The signal of a sensor 23 is changed between Low and High according to waste toner quantity T by operation of a detection auxiliary member 25 disposed within a recovery container 20. It is repeated to operate the detection auxiliary member 25 synchronously with rotation of a leveling member 21 and periodically change the signal of the sensor 23 between High and Low. When the content of the recovery container 20 reaches a predetermined quantity, the signal remains Low without change. In such a case, it is determined that the content of the recovery content 20 reaches the predetermined quantity, and a full or nearly full state of the recovery container 20 is displayed on a display part provided on an operation part of an image forming device or the like and reported to a user.

摘要： PROBLEM TO BE SOLVED: To provide a device capable of opening and closing a shutter member responding to a slight displacement of a recovery case for a waste toner and capable of effectively preventing the waste toner from spilling. SOLUTION: A shutter member 32 is opened and closed in such a manner that when a toner recovery case 38 is set, a projection provided on the toner recovery case 38 moves a lever 35, which operates the shutter member 32 via a connecting member 34. When the toner recovery case 38 is detached, the projection is disengaged from the lever 35 to close the shutter member 32 by a forcing means 36. The waste toner 39 is carried by a carrying coil 33 placed inside a toner carrying pipe 31 and dropped into the recovery case 38 through a toner discharge port 40 provided at an end of the toner carrying pipe 31. The moving distance of the toner recovery case 20 is the sum d+a of the moving distance (d) of the case until the discharge port 40 enters the recovery case 38 and the moving distance (a) until the shutter member 32 is opened. The moving distance can be extremely reduced compared to a moving distance of a conventional device, and thereby, a small-sized device with a saved space can be obtained. COPYRIGHT: (C)2009,JPO&INPIT
