It is preferable to configure the unit 140 to operate to fill the cartridge 10.

Thus, look at the operation of the toner refilling apparatus of the present invention configured as follows.

First, the power is supplied by operating the operation unit 163 formed on the front surface of the casing 111 of the main body unit 110, inputting an operation value according to the type of the cartridge 10, and the controller 161 of the controller 160. (10) The cartridge 10 is mounted to the cartridge mounting part 112 by opening and closing the opening 113 formed in the front of the casing 111 in the state of calculating the filling amount according to the type.

Thus, in the state in which the cartridge 10 is mounted, the supply fastening part 149 of the pressurizing part 140 is fastened to the fastening part 123 of the toner injection part 120 formed on the upper part of the cartridge 10 toner injection part. Toner supply pipe 147 is installed to be firmly connected to the injection port 121 side of 120, and when the installation is complete, the coupling sensor 164 of the control unit 160 formed on one side of the supply fastening unit 149 is detected and the controller In step 161, the combined signal is sent.

At this time, the coupling sensor 164 formed at one side of the supply fastening unit 149 of the pressing unit 140 fills the toner in the toner supply pipe 147 and the cartridge 10 to which the toner is pressurized by the pressing unit 140. By continuously checking the coupling state of the injection hole 121 of the toner injection unit 120 and disengagement of the toner injection unit 120, the controller 161 of the control unit 160 stops the supply of the toner, thereby preventing the toner from leaking. do.

As described above, the cartridge 10 is mounted on the main body portion 110 to the cartridge mounting portion 112, and the toner injection portion 120 formed on the upper portion of the cartridge 10 is coupled to the pressurizing portion 140 in the front surface. When the opening and closing port 113 is blocked, the cartridge 10 is formed in the lower portion of the casing 111 by weighing the correct weight in the weighing port 151 in a state in which the cartridge 10 is placed in the cartridge settlement portion 152 in the correct position. The weight measured in the weighing unit is signaled to calculate the filling amount according to the cartridge 10 type set as the operation unit 163 and the remaining amount of toner on the controller 161 while displaying the weight measured on the front side of the display unit 162. do.

In this way, when the controller 161 receives the weight of the cartridge 10 from the metering unit 150 from the controller 161 and starts supplying the amount of toner determined by the operation to the operation unit 163, the main body unit 110 is provided. The stirring blades 133 of the supply hopper 131 having the toner stored thereon are rotated to form a plurality of stirring gears 132, which are stored there for a long time, so that the toner is smoothly supplied to the aggregated toner. Supply to the formed supply screw 135.
