Abstract

PURPOSE:To smoothly move a toner to the flexible membrane member of a toner detector to transmit its pressure to it, and to enable actuation of a pressure sensor before the breakdown of a container by forming a guide for guiding the toner toward said membrane member. CONSTITUTION:The first guide 20 interrupts the course of the toner moving from its right side and forces the toner to direct its flow direction toward the side of the membrane member 12, as shown in the arrow mark I . The second guide 21 forces the toner liable to remain in a part G to smoothly send the toner to the member 12. The course of the toner from the pressure-applied part in the toner container 5a to the member 12 is smoothed, and the toner smoothly moves to the member 12. Before the toner pressure becomes locally too high, a prescribed pressure is transmitted to a pressure sensor 13 to actuate the sensor 13 to operate and to detect an amt. of toner in the container.

The toner is sequentially fed into the container and the toner accumulates in the container HH, but at this time, the pressure of the toner in the container, in other words, the density of the toner is not uniform throughout, but locally. There are areas where the toner pressure is high and areas where the toner pressure is low. In general, the pressure of 1-→゛- is usually high at the corner or corner of (1):(. Even though the toner pressure is extremely high in corners and the like, the toner pressure acting on the membrane member is low, and a situation may occur in which the pressure-sensitive sensor cannot detect this. If the container is filled with a large amount of toner but cannot be detected, more 1-toner will be fed into the container, and the 1-toner pressure inside the container will increase locally. In extreme cases, the container may be damaged by one hemonic pressure.

The configuration described in Section 7, except for -1=Guide 20.2],
There is no difference from the cleaning device related to the prior order that has already been proposed by the present applicant. In this case, the toner detection devices 1 to 10 detect the amount of toner in the container as follows, and the container can be replaced accordingly. The amount of toner in the container 5, in this example, the toner storage portion 5a, increases gradually, and the toner reaches the height level of the membrane member 12, and is transmitted through the membrane member 12 to the vibrator 16 of the pressure-sensitive sensor 13.
When the pressure starts to be applied, the frequency of the vibrator 16 changes due to the pressure. When this frequency decreases to a predetermined value, a 1tH full signal is generated, which causes a display (not shown) attached to the copying machine to display that the container should be replaced, or You will be notified by a buzzer.

Knowing this, the operator removes the container 5 along with the attached elements from the main body of the copying machine and installs a new container. During this replacement work, the pressure-sensitive sensor I3 remains attached to the main body of the copying machine, and the unit consisting of the container 5 and the previously installed elements is removed.
only are exchanged. Therefore, even if the removed container is discarded, there will be no waste such as discarding the sensor 13. When removing the container, the opening 11 is covered by the membrane member 12, so the opening 11
No more toner spilling out. If the photoreceptor 2 and the roller 3 are also configured as an integral unit with the container 5, and the whole can be removed from the main body of the copying machine, there is a possibility that the 1 to 3-ners will come out from the opening formed on the right side of the container 5. There will be no more.

As shown in the double series, the toner is sequentially fed into the toner storage section 5a of the container 5 by the pressure of the 1-toner feeding member 7, but since the 1-toner itself does not have the ability to move, the toner is sent to the toner storage section 5a
The toner inside is moved by the pressure from the 1-toner fed by the feeding member 7 and is stored in the storage portion 5a. At this time, unlike liquids, powders such as toner do not exist at a uniform pressure or uniform density within the container, but locally
~ It was explained earlier that the pressure tends to increase. This will be explained using the container 5 of the cleaning device according to the prior application in which the guides 20 and 2+ are not provided, with reference to FIG. When the toner storage portion 5a becomes clogged, the lower corner H of the toner storage portion 5a surrounded by the chain line in FIG.

On the other hand, the pressure of the toner existing in areas other than these areas H, E, F, and G is relatively low, so
Even if the pressures of E, F, and G become excessive, the 1-toner pressure applied to the pressure sensor 13 via the membrane member 12 remains low, making it impossible to detect that the container is full of toner. As described above, there is a risk that the container may be damaged by the toner pressure before this detection is performed.

- In order to eliminate the drawbacks mentioned above, the toner flowing into the container, in this case the toner storage portion thereof, is actively guided to the cup-shaped top 1.2c of the membrane member 12, so that the toner pressure in the container is reduced. What is necessary is to allow a pressure equal to or higher than a predetermined value to act on the pressure-sensitive sensor 13 via the membrane member 12 before the pressure becomes locally excessive. The thing that performs this work is the 11th one shown in the simple lit earlier. and second guides 20, 21, and the first guide 20 is formed into a substantially semi-cylindrical shape as shown in FIG. Further, the second guide 21 is formed into a plate shape, and the end thereof is connected to a wall 5.
