Abstract

PURPOSE:To easily attach and detach a container, and also, to prevent a toner from being scattered, by engaging a projection of an opening side of a toner container and a recessed part of the bottom face to a container holder and holding horizontally the container, and oscillating it to the second position. CONSTITUTION:An opening 2 of a toner container 1 is kept horizontal and inserted into a rotary cylinder 7 of a container holder 5, and thereafter, when a recessed part 20 of the bottom face of the container and a projection of a container holder 19 are engaged and the opening 2 is rotated downward, a toner in the container is led by a spiral projection 4, passes through the opening and dropped down into a toner receiver 11. When the bottom side of the container is oscillated to this side in the horizontal direction, a cam 17 presses the presser 19 against a spring 18 and the container becomes freely attachable and detachable. Since a projection 3 of the container is engaged to a groove 9 of the cylinder 7, when the opening 2 has been set to the lower side, the container cannot be removed from the holder 5, and the toner does not spill. In this way, the toner container can be attached and detached easily, and also, scattering of the toner can be prevented.

Description

【発明の詳細な説明】 （産業上の利用分野） 本発明は、静電転写式複写機の現像部分へトナーを供給
するトナー補給装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a toner replenishing device for supplying toner to a developing section of an electrostatic transfer copying machine.

（従来の技術） 静電転写式複写機の現像装置でトナーと称する乾式若色
粒子が用いられ、コピーの都度、コピー用紙に付着して
持っていかれるトナーを常時一定の割合で現像装置の中
へ補充する必要がある。(Prior art) Dry young colored particles called toner are used in the developing device of an electrostatic transfer copying machine, and each time a copy is made, the toner that adheres to the copy paper and is carried away is constantly transferred into the developing device at a constant rate. It is necessary to replenish.

いられている。Conventionally, as this replenishment means, a device for replenishing a fixed amount of toner called a toner hopper is provided, and toner is transferred from a container such as a bottle into this hopper, and some of the various methods are transferred from this hopper during copying. A metering mechanism is used to supply a fixed amount of toner into the developer device.

この方式では、びん等の容器からホッパー内へトナーを
いれる際に微粉状のトナーが舞い上がり。With this method, when toner is put into the hopper from a container such as a bottle, fine powder toner flies up.

周辺や操作者の手等を汚す欠点があった。This had the disadvantage of staining the surrounding area and the operator's hands.

た。Another method is to use a container such as a bottle as it is as the hopper container, and attach the toner container to the joint of the hopper with the opening of the bottle facing upward, so that the mounting part is sealed. There is a method in which the toner container bottle is rotated to nearly 90'' or 180'', and the L-toner that falls due to gravity is sent into a fixed amount metering mechanism to supply the toner into the developing device. Since there is no need for the operator to transfer the toner into the hopper, the surrounding area will not be contaminated, but the toner container must be rotated from a vertical position to a 90" or 180° position. This rotation required a large space, which was an obstacle in designing a compact copying machine.

ることもない。When the container rotating cylinder 7 is rotated by the motor 8, a positioning switch (not shown) is used to ensure that the cylinder 7 rotates once and then stops at a position where the groove 9 and the opening 10 are on the upper side. When the cylindrical toner container 1 is rotated once by the drive motor 8, the toner inside spills out when the opening 2 of the cylindrical toner container 1 is rotated once by the drive motor 8, and the toner inside spills out into the toner receiver 11 provided on the lower side of the container holding and fixing part 6. drop down. There is a coil 12 inside the toner receiver 11, which is rotated by a drive motor 8. The toner coming out of the opening 2 of the cylindrical toner container 1 flows through the toner receiver 11 and into the coil 1.
2, it is sent to the right in FIG.
Go inside. Therefore, in one rotation of the cylindrical 1-toner container 1, a certain amount of toner coming out of the opening 2 is sent to the developing device 14. The receptacle for the cylindrical toner container 1 of the container holding/fixing part 6 is provided with a notch 15 on the upper side around the opening. The container cannot be attached or detached. Therefore, when the cylindrical toner container 1 is rotating and the opening 2 is on the lower side, the toner cannot be pulled out of the toner replenishing device and the toner will not spill out.

By configuring the holding container holder to be detachable, the cylindrical toner container can be easily attached and detached with the container holder tilted to the second position, and toner can be replenished extremely easily without causing toner scattering. . Furthermore, when the toner container is swung to the first position, the cylindrical toner container is automatically locked by the container holder, thereby preventing it from slipping off during toner replenishment. Further, since the container holder is simply swung between the first position and the second position, the replenishing device can be made compact and has many practical effects.
