The pair of leg pieces (31), (32) are folded downward along the folding line (32), (36) with an obtuse angle with respect to the placement section (10) and then lower edges (31b), (35b) of the pair of leg pieces (31), (35) are engaged with boundaries between the bottom plate (41) and the side plates (42a) of the packaging box (4).

Abstract: A packaging box (1) includes a storage part (2), an inner flap (21) and an outer flap (22). The inner flap (21) is provided with a slit (31) along an edge (11a) and the outer flap (12) is provided with an insertion piece (41) connected to a tip edge (22a) via a bending line (42). The insertion piece (41) is inserted into the slit (31) by being bent along the bending line (42). The insertion piece (41) has an engaging piece (45) configured to be foldable along a folding line (44) extending in a direction crossing the tip edge (22a) and to have an engaging edge (45a) facing the tip edge (22a). When the engaging piece (45) is folded along the folding line (44), the engaging edge (45a) is inclined downward toward its distal end.

Abstract: A packaging box where a body part has a bottom plate, first side plates erecting from one opposed edges of the bottom plate and second side plates erecting from other opposed edges and is provided with an opened upper surface. A pair of inner flaps are connected to upper edges of the first side plates through fold lines and folded inside. A pair of outer flaps are connected to upper edges of the second side plates through fold lines, and folded inside and overlapped with the pair of inner flaps to close the opened upper surface. Each of the pair of inner flaps is provided with a first engaging part. Each of the first side plates is provided with a first engaged part, which may engage with the corresponding first engaging part when the pair of inner flaps are folded and overlapped with the outsides of the first side plates.

Abstract: Disclosed is a toner supply device including a toner container section (21b), a rotating shaft (31) provided in the toner container section (21b), and a stirring member (32) for stirring and feeding toner T to a supply opening (21d) formed in the toner container section (21b). The stirring member (32) includes an attachment portion (32c) fixedly attached to the rotating shaft (31) and a free end portion (32d) free to the rotating shaft (31). The free end portion (32d) has a stiffness lower than the attachment portion (32c). With this construction, a toner feeding rate can be maintained by the attachment portion (32c) and sound occurring at a release of the free end portion (32d) can be suppressed due to the free end portion (32d).

Abstract: A sheet separating/conveying mechanism 30 has an upper unit 30a in which a paper feed roller 31 and other components are arranged and a lower unit 30b in which a separating roller 32, an arm member 36, and other components are arranged. The arm member 36 is U-shaped as seen in a plan view by being composed of a left and a right movable lever 36a that are mutually parallel and that make contact with both ends of a center shaft 23b and a pivot shaft 36b that supports the movable levers 36a so that they are rotatable in a direction indicated by arrow BB?. The movable levers 36a have locking holes 39 formed at the tip ends thereof, and the lower ends of tension springs 38 are locked in those locking holes 39. The lower unit 30b is fitted with an applied force adjusting member 45 on which locking portions 42a and 42b are formed to protrude therefrom leftward and rightward that permit adjustment of the positions at which the upper ends of the tension springs 38 are locked.

Abstract: The provision of the overlapped transfer-preventing mechanism having a pivot 5a integrated with the lower separating roll 5 which is variably separated from the upper separating roll 4 rotably driven, the lower separating rolls is rotable in a direction opposite to said paper supplying direction when the lift plate 37 is lifted up in a paper-supplying position.

Abstract: An overlapped transfer-preventing mechanism that is inexpensive, simple in construction, requires no actuator and has a high degree of freedom of layout. The mechanism includes an upper, rotatably driven, separating roll and a pivot integrated with a lower separating roll. The pivot is provided with a one-way clutch which prevents rotation of the pivot in a paper-supplying direction but which permits rotation of the pivot in the direction opposite the paper-supplying direction. The one-way clutch has mounted on it a lever member, which is engaged with a paper-carrying plate by an upward or downward moving operation of the paper-carrying plate so as to rotate the one-way clutch in the direction opposite the paper-supplying direction.

Abstract: The present invention relates to a display for image forming apparatus to enable indication of the number of processing sheets and also indication of impossible paper feeding on the paper feed pass on one display by time-sharing at different times, and particularly concerning the point that indication of disabled paper feeding and indication of the above mentioned number of processing sheets are made alternatively when the indication of disabled paper feeding is given by providing a paper sensing switch in the paper supplying mechanism.
