Abstract

PURPOSE:To prevent toner blocking by attaching elastic sheets having a suitable number of through-holes into a cantilever state to the side walls on the upper side of an agitator provided in a toner box and oscillating elastically said sheets by the rotation of the agitator. CONSTITUTION:A toner box 2 is provided on the upper side of a feed roll 1 and an agitator 3 driven by a motor 4 is attached in the bottom thereof. Elastic sheets 6 having a suitable number of through-holes 7 are attached into a cantilever state to the side walls of the box on the upper side of the shaft part of the agitator 3. The sheets 6 are elastically oscillated by the rotation of the agitator 3. A toner 5 is thus uniformly agitated to the corners of the box and the blocking of the toner is nearly thoroughly prevented.

(Prior Art) A toner blocking prevention device in a conventional toner supply device such as a copying machine has a toner box 2 provided with a supply roll 1 at the lower inner side, as shown in FIGS. 1 and 2, for example.
In contrast, an agitator 3 made of wire or the like in a substantially hat shape is arranged at a suitable position inside the box 2, and this is rotated by a motor 4Vc provided on one side of the box 2, so that the toner 5 stored in the box 2 is blocked. was prevented from occurring. However, in the toner blocking prevention device having such a structure, toner blocking does not occur within the range in which the agitator 3 is rotating, but blocking 6 occurs outside the rotating range at high temperature and high humidity. Ta. In addition, if the toner box 2 itself is deformed due to space constraints as shown in FIG. 3, the IF in the plan view of FIG.
There is a drawback that blocking 6 cannot be avoided in the I-line portion.

(Embodiments) The present invention will be explained in detail below based on embodiments shown in the drawings.7 Fig. 4 is a cross-sectional front view showing an embodiment of the toner blocking device of the present invention, and Fig. 5 is the same, an elastic sheet. FIG. A toner box IK is provided with a supply roll 1 at its inner lower part, and an agitator 3 made of wire or the like bent into a substantially hat shape is rotatably arranged at a suitable position at its inner upper part.
This is connected to a motor 4 provided on one outside of the toner box 2, and elastic sheets 8, 8 with through holes T...
The agitator 3 is disposed in a cantilevered manner on the side wall of the agitator 3, and is relatively arranged from both ends of the agitator 3 toward the inner center.

The toner 5 stored in the toner box 2 is first agitated within the range of 30 rotations by the motor 40 rotations to prevent blocking. At this time, as the agitator 3 rotates, the upper toner 5 that is outside the rotation range of the agitator 3 is brought into contact with elastic sheets 8, 8 having through holes 1... 8 and 8 in the vertical direction using their elasticity, thereby preventing blocking. When the elastic sheets 8, 8 move in the vertical direction, the through holes T... are formed in the elastic sheets 7.
When the toner 7 moves upward, it serves to cause the toner 5 on top of the toner 5 to fall downward.
