Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic copying machine that forms a toner image on the surface of a photoreceptor drum using a dry oven and transfers the toner image to paper. , regarding a device that can easily replenish toner to a toner hopper provided in a device such as a printer, and in particular, interlocking the sliding lid provided on a toner cartridge with the sliding lid of the toner hopper. The present invention relates to a device configured such that when the sliding lid is moved in a closed state, a film seal provided to cover the sliding lid moves in conjunction with the sliding lid to open and close the opening.

(Prior Art) Conventionally, devices such as copying machines and printers use dry toner, and use the toner to form a toner image on the surface of a photoreceptor drum, and then transfer the toner image to paper. equipment is used.

In such devices, the toner in the developing machine is gradually consumed as the number of copies increases.
It is necessary to replenish toner every time a certain number of copies are made.

In conventional devices such as electronic copying machines, the toner used in the developing device of the electronic copying machine is either a -component toner or a two-component toner, depending on the characteristics of the copying machine. Toner may be used, but in any case, it is necessary to replenish the toner every predetermined number of copies.

As mentioned above, the most common method for replenishing toner in developer*a is to open the cartridge containing toner and transfer it directly to the toner hopper.
When such a method is used, there are inconveniences such as the toner scattering around and staining the area around the developing device.

Therefore, a method has been used in which the gutter is housed in a cylindrical cartridge and the cartridge is inserted into the hopper of the developing device. This type of cartridge has an opening in the longitudinal direction of the side of the cylinder that houses the toner, and the opening is covered with a sheet. After being installed in the developing device, the opening can be opened by pulling out the sheet. form and allow the toner to fall.

Therefore, in the case of such a toner replenishing device, the frontage of the cartridge is not exposed outside the copying machine body, so even if the operator is careless, toner may scatter from the cartridge and cause damage to other parts of the copying machine. This will prevent any inconvenient situation from occurring, such as contaminating the equipment.

However, when using a cylindrical cartridge like the one mentioned above,
A device that is attached to a fixing device or a copying machine main body has a drawback that the cartridge housing portion thereof becomes a dead space. In addition, in small-sized copying machines, the amount of toner consumed is small, so a relatively small cartridge can suffice, but in relatively large devices such as electronic copying machines that copy at high speed, the toner consumption is proportional to the number of copies. Therefore, toner consumption increases.

However, although the main flange of the developing device can be made relatively large, making the toner cartridge large means that the dead space in the cartridge accommodating section becomes large, and other mechanisms of the copying machine are affected. There are disadvantages such as adding restrictions.

In order to overcome these drawbacks of conventional devices, a toner container with a special J1RA lid was used, as shown in Japanese Patent Application Laid-Open No. 59-36''268. is proposed.

The toner receiving device shown in the above-mentioned conventional example has a first
As shown in FIGS. 2 and 13, the toner container 1a has an opening formed on the lower surface of a substantially rectangular cylindrical main body,
Seal the opening with the film seal 20a and slide 11 Q
This is covered by a.

Then, the toner receiver provided in the toner hopper of the developing device is installed in the side of the container lower frame 5a after the toner container 1a is opened and the position of the container lower frame 5a is fixed. When the slide 110a is slid along the raised protrusion 7a, the film seal 20a is peeled off from the area around the lower opening of the container 1a. Therefore, as shown in FIG. 13, an opening 3a is formed in the F portion of the main body of the toner container B1a, and the toner falls from the opening into the toner hopper at the developing device 5A.

In the conventional toner replenishing device as described above, all that is required is to set the toner container in the toner hopper of the developing device and move the slide lid together with the film seal.
An opening can be formed in the container, and toner can be replenished in an almost airtight state without staining the surrounding area of the developing device.

(Problems to be Solved by the Invention) However, in the toner replenishing device having the above-mentioned configuration, when the film seal is peeled off from the lower part of the main body of the toner container and moved along the lower surface of the slide lid, , the surface of the film seal that was in contact with the toner,
The toner will be exposed on the bottom surface of the slide lid, and as a result, the area around the small toner flange of the developing device or other parts of the copying machine other than the developing device may be contaminated by scattered toner. There are many.

To deal with this, a method is used in which a cover member is provided near the upper opening of the toner hopper to prevent the dirt at the bottom of the film seal from scattering around. Even if you use such means,
The effect of preventing scattering of toner cannot be sufficiently exhibited.

Furthermore, in the conventional apparatus described above, the mechanism for sealing the toner on the toner hopper side is complicated and has a large number of parts, which tends to affect the manufacturing cost of the developing station or toner cartridge. was there.

In response to this, the inventors of the present invention previously proposed a toner replenishment V device having a configuration as shown in FIGS. 10 and 11. In this illustrated toner supply device,
An opening/closing lid device configured by combining a slide lid 10 and a film seal 20 is provided at the bottom of the toner cartridge 1, and a slide lid 50 and a film seal are also provided on the toner hopper 40 side in correspondence with the r'tIi device. 3
An opening/closing lid device consisting of 0 is provided.

By moving the slide lid 50 via the knob 56 provided on the slide N50 on the toner hopper 40 side, the film seals 20.30 interlocked with the slide lid 50 via the holding members 22.32 are respectively attached. The sliding lid 10.50 is moved to form an opening between the toner cartridge 1 and the toner hopper 40.

By configuring as described above, the surfaces of the film seals soiled with toner at the respective openings of the toner cartridge 1 and the toner hopper 40 overlap as shown in FIG. Since dirt is not exposed on the surface, it is possible to prevent dirt from being generated by opening and closing the slide lid of the torch storage section of the copying machine, and it also has the effect of making toner replenishment very easy. be done.

Further, in the toner replenishing device as described above, when fixing the toner sheet cartridge 1 to the toner hopper 40, the protrusion provided on one side of the lower frame 5 of the toner cartridge 1 is inserted into the upper guide 45. At the same time as locking at the bottom,
A locking member 55 provided on the main body side is locked to the protruding members on both sides of the toner cartridge by movement of the knob 56, and performs an operation to fix the toner cartridge 1 so that it does not come off from the toner hopper 40.

However, with the above configuration, the configuration of the lower part of the toner cartridge 1 becomes complicated, and
The number of operating members such as locking members and locking members on the copying machine main body increases, which not only complicates the structure but also causes problems such as affecting the manufacturing cost of the copying machine main body. .

Furthermore, when using the interlocking relationship between the slide lid and the film seal as described above, the movement of the upper and lower slide lids and the movement of the film seal are performed at the same time. Since the operation of peeling off the adhered film seal 20 from the toner cartridge main body is performed simultaneously with the movement of the light base, the operation of forming the opening by moving the knob requires relatively force.

In addition to this, the film seal 30 on the toner hopper side
Since a part of the film seal is fixed to the hopper upper member 41 via the adhesive part 31, if an accident occurs in which the film seal breaks, the film seal must be replaced. However, it is desirable to be able to easily deal with accidents such as damage to the film seal.

For the above-mentioned reasons, there is currently a demand for the development of a device that is easier to use with regard to the toner cartridge and the toner hopper on the copying machine main body side, even in devices such as the toner replenishing device.

(Objective of the Invention) The present invention solves the above-mentioned drawbacks of the conventional device.The present invention simplifies the structure of the toner cartridge, prevents the toner from scattering to the surroundings, and prevents the toner from scattering. The purpose is to provide a device that can easily replenish toner to a hopper, and further,
To enable a container to be held in a fixed position when a toner cartridge is set in an opening of a toner hopper and replenish toner, and to allow a film seal on the toner cartridge side to be easily peeled off. An object of the present invention is to provide a toner replenishing device provided with a mechanism.

(Means and effects for solving the problem) The gutter replenishing device of the present invention is provided with an openable and closable base member at the frontage of the toner hopper of the developing device provided in the main body of the copying machine, and is set on the base member. The toner cartridge for supplying toner is also provided with an openable and closable lid member.

Each of the above-mentioned lid members is composed of a slide lid and a film seal, and the portion of the slide lid that contacts the toner is covered with the film seal, and a film holding member is attached to the end of the film. The film holding members are configured to have the same shape.

Further, in the toner replenishing device of the present invention, the slide lid of the toner cartridge and the slide lid of the toner hopper are combined so as to be interlocked, and a film seal is provided to cover the slide lids of both members. , the respective holding members are assembled with a margin in the sliding direction, and the peeling operation of the film seal on the toner cartridge side is configured to be delayed with respect to the movement of the slide lid.

Therefore, in the toner replenishing device of the present invention, by setting the toner cartridge in the upper part of the hopper, the slide lid and the film holding member are combined with each other, and by sliding one of the slide lids, The lids provided corresponding to the slide lids are moved, and the film seals provided corresponding to the slide lids are slid.

Furthermore, when replenishing toner, the operation of peeling off the film seal on the toner cartridge side is carried out after the movement of the slide lid, so when forming the opening, the slide lid can be moved relatively lightly. Become what you can.

(Embodiment) The configuration of the toner replenishing device of the present invention will be described according to the illustrated embodiment.

As shown in FIG. 1, the toner replenishing device of the present invention includes:
This device is configured such that toner is supplied by a toner cartridge 1 to a toner hopper 40 provided in a developing device of a copying machine main body.

The toner cartridge 1 of the present invention is composed of a container body 2 formed in a substantially cylindrical shape and a lower frame 5 provided at the lower part of the container body 2.
The IM port provided on the lower frame 5 is sealed with a slide lid 10 and a film seal 20.

These lower sealing members of the toner cartridge 1 are designed so that the opening of the toner cartridge 1 is opened and closed in conjunction with the opening and closing of the upper sealing member of the l/ner hopper 40, as will be described later. It is configured. In addition, in the above explanation, the tip part and the end part are
When the toner cartridge is installed in the toner hopper, the direction in which it is first inserted, that is, the side where the tip insertion part 6 is provided is called the tip part, and the side on the rear end protrusion 8 side is called '4! Since this is called the It end, the slide lid is slid toward the rear end when forming the opening.

The slide M10 provided for sealing the opening of the toner cartridge 1 is configured as a substantially flat member, and slides along a guide portion 5x provided in the lower frame 5, as shown in FIG. It is now possible to do so.

Further, the film seal 20 used to seal the opening together with the slide lid 10 has its -Oa portion glued to the lower part of the rear end protrusion 8 side of the lower frame 5, and the other end of the film seal 20 used to seal the opening. It passes through the distal end side of M10 and is connected to the holding member 22.

This holding member slides along a guide groove 11 provided at the bottom of the slide lid 10, and as will be described later, the film seal 20 is driven in conjunction with the film seal 30 on the toner hopper side. There is.

Further, the lower frame 5 of the toner cartridge 1 has a leading end insertion portion 6 on one side and a rear end protrusion 8 on the other side.
are provided respectively, and by these members 6.8,
The toner cartridge 1 can be fixed to the toner hopper 40.

As described above, the toner hopper 40 of the copying machine main body is configured so that its toner supply port is sealed by a slide 1ft50 and a film seal 30, but these two members are not attached to the toner cartridge 1. The structure is similar to that of the seal member provided.

Moreover, the slide lid 50 provided on the gutter hopper 40 is
It has almost the same configuration as the slide 110,
A film seal 30 formed in a loop shape is arranged to cover both the upper and lower surfaces of the slide M50. Furthermore, in order to guide the film seal 30 along the upper and lower surfaces of the slide lid 50, an O-ra 51 is provided on the rear end side of the slide lid 50 in the illustrated embodiment. The film seal 3 is sealed by the roller 51.
0 sliding resistance can be reduced.

Then, by sliding the slide M50 above the opening by a driving knob provided on the toner hopper, the slide M50 is moved together with the slide M10 of the toner cartridge 1, and the openings of both members are opened and closed. That's what I do. The movement of the film seal 30 follows the sliding movement of the slide lid 50, and the structure of the film seal 30 and the movement of the film seal 20 will be explained later.

In addition, in the device of the present invention, in order to interlock the upper and lower slide lids 10.50 disposed in the opening, four corner portions of the slide lid 50 are provided as shown in FIG. Locking claws 53 are provided at intervals t, and engagement recesses 13 are provided in the slide W110 in correspondence with the claws 53.

When the toner cartridge 1 is set in the toner hopper 40, the engagement members provided on the upper and lower slides l110.50 are engaged, and at the same time, the holding member 22 of the film seal 20 and the engagement member of the film seal 30 are engaged. 3
2 are respectively engaged to form a film seal 20.30.
and the slide lid 10.50 are slid in conjunction with each other, thereby opening and opening the opening for toner replenishment.

The film seal 30 provided to the small toner collar 40 has a structure as shown in FIGS. 6 and 7, and is a holding member having a protrusion 32a formed in the center of the film made by Plus Book. 32 and an end member 35a for forming a connecting member 35 at both ends thereof,
35b8 is provided.

These end portions U35a, 35b are approximately dogleg-shaped members, as shown in the figure, and each end portion has a bottle 3.
6a and the hole 36b are provided to face each other, and further,
Both members are fixed and integrated by double-sided chees 136!
I'm starting to get it.

Therefore, the two end members 35a, 35 as described above
By connecting b, the film seal 30 is formed into a substantially endless shape, and the connecting member 35 is disposed protruding from one side of the loop-shaped film, and the holding member 32 is disposed protruding from the back side. . Then, the connecting member 35 is fixed to the locking hole 43 installed in the toner hopper upper member 41 as shown in FIG. As a result, when the toner cartridge 1 is set on the toner hopper 40, the upper and lower film seals 20, 30 are moved in conjunction with each other.

By configuring the film seal 30 of the present invention as described above, the film seal 30 on the toner hopper side
If the film seal 30 is exposed due to some kind of accident, the task of replacing the film seal 30 can be carried out very easily. In other words, when replacing the film seal 30, the film seal 30 can be formed into one sheet by separating the end members of the loop-shaped film seal, and the operation of removing it and replacing it with a new one can be done. This means that the work of attaching the film seal can be easily performed.

Further, as described above, the film seal 20 of the present invention.
30, as shown in FIG.
The protrusion 32a of the holding member 32 of the film seal 30 that engages with the protrusion 32a is arranged with some play.

Then, when the slide lid 10 and the film seal 20.30 are respectively moved following the movement of the slide lid 50, the slide M10 and the film seal 30 start to move together with the slide 150. The film seal 20 starts to move with a slight lag with respect to the movement of each of these members, and as a result of this movement, it is peeled off from the lower surface of the lower frame 5 of the toner cartridge 1.

During the operation of forming this opening, slide 110.
The film seal 20 is peeled off with a slight delay in the movement of the film 50. Since the film seal 20 is peeled off following the sliding lid which has inertia, the initial movement of the sliding lid is carried out easily, and the burden on the operator can be reduced.

When forming the above-mentioned frontage, as shown in FIG. 5, when the slide 1150 is moved, the slide M10 is attached to the slide lid 50 via a claw so that it can be moved integrally with the slide M10. Move in the direction of the arrow.

When the slide lid is moved, the connecting member of the film seal 30 is fixed to the upper member of the toner hopper, so the film seal 30 is sequentially slid with the tip end of the slide 1150 being rolled up. The upper surface of the film seal 30 functions to move the film seal 20 on the toner cartridge 9 side via the holding member 32. In this case, the film seal 20 moves against the sliding of the slide 110. Since a slight deviation occurs in the sliding movement of the slide 110, a small loop is formed in the film seal on the rear end side of the slide 110.

That is, during the above-described operation, the amount of sliding of the film seal 30 is set to be twice the moving distance of the slide M50, so that the film seal sealing the upper part of the gutter hopper 40 The toner-stained surface of the toner cartridge 30 and the toner-stained surface disposed on the top surface of the film seal 20 of the toner cartridge 1 are
It will now be moved between the upper and lower sliding lids.

Therefore, the toner-stained parts of the upper and lower films will not be exposed to the outside, and the toner will scatter and stain the top of the toner hopper, and dirt will adhere to unnecessary parts of the copier body. Such problems will not occur.

Further, as shown in FIG. 9, the toner cartridge of the present invention is provided with the front end insertion portion 6 and the rear end projection portion 8 at the front and rear portions of the F frame 5 as described above. Among the members, the tip insertion portion 6 is provided with recesses 6a and 6b, and the toner cartridge is fixed by engaging the recesses with engagement bins 47a and 47b provided on the main body frame. It is configured so that it can perform an action.

Furthermore, recesses 6a and 5b provided in the tip insertion portion 6 described above.
can be used as a toner cartridge identification code depending on the combination of their positions, and depending on the set position of these recesses, the type of toner, the type of copying machine that can be used, and other signals can be given. becomes possible.

Therefore, in the toner cartridge of the present invention, the color and type of the toner in the toner storage capacity D1, the model of the copying machine that can be installed, and other indications are provided on the member 6, so that an inappropriate toner cartridge can be installed in the copying machine. It is possible to prevent this from happening.

The upper part of the toner hopper 40 for mounting the toner cartridge of the present invention can be constructed as shown in FIGS. 3 and 4. In the illustrated embodiment, an upper member 41 is provided to cover the top of the toner hopper 40, and a guide 45 is further disposed on the upper part of the upper member 41.
50! ! be moved. The two plate members disposed above the toner hopper are attached to the frame of the toner hopper using fixing screws 48.

As explained above, for this slide lid 50,
At each of its four corners, claws 53 are provided to protrude, respectively, and these claws 53 are used to lock the slide 110 of the toner cartridge 1.

Further, in this embodiment, a slide member 57, 57 is provided protruding from the tip end side of the slide lid 50, and the slide member is slid on a rail member provided on the upper frame of the toner hopper. 50 movements will be provided.

On the tip end side of the toner hopper 40, there is a stopper 60 that is swingably supported by a shaft 61;
A presser spring 63 is arranged to press the distal end side of the holder. This stopper 60 is provided with a protrusion 62 on its tip side, and when the protrusion 62 is inserted into a recess 58 provided in the slide member, it becomes possible to prevent the slide [50 from sliding. The opening of the toner hopper is prevented from being opened.

This stopper 60 is connected to the toner cartridge 1.
When the slide 150 is inserted, it is pressed by the tip insertion portion 6 of the toner cartridge 1 and swung against the pressing force of the presser spring 62, and the protrusion 62 comes out of the recess 58, so that the slide 150 56 and can be easily moved.

Furthermore, as shown in FIG. 3, the above-described stopper 60 of the present invention can restrict excessive movement by providing a concave portion on the rear end side that engages with the locking pin 47. It is possible to perform the operation accurately.

Next, the operation of replenishing toner to the toner hopper 40 using the toner cartridge of the present invention will be described according to the example shown in FIG. 1 and FIG. 3.4. first,
When installing the toner cartridge 1 having the structure shown in FIG. 1 into the toner hopper 40 having the structure shown in FIG. is inserted between the upper member 41 on the distal end side and the guide 45, and then the rear end protrusion 8 is inserted by pushing the latch 46.

By the operation of attaching the tip insertion portion 6 of the toner cartridge 1 described above, the slide lid 50 is moved by the stopper 60.
The lock is released, and the slide M50 is in a state where it can be slid by the knob. Further, two plate members 41 and 45 disposed at the upper part of these toner hoppers are attached to the frame of the toner hopper using fixing screws 48.

By inserting the toner cartridge 1 into the upper part of the toner hopper 40 as described above, as shown in FIG.
The slide lid 10 of the toner cartridge 1 is assembled so that the claw 53 is engaged with the engagement recess so that both members can slide together. At the same time, the film seal 20 of the toner cartridge 1 and the film seal 30 of the toner hopper are combined with holding members 22 and 32 provided respectively, so that the upper and lower film seals slide in conjunction with each other.

In this state, when the knob 56 provided on the side of the toner hopper 40 is moved toward the rear end, the slide H5
0 and the slide device 10 are simultaneously slid toward the rear end side as shown in FIG.

However, the film seal 20 on the toner cartridge 1 side
Since the protrusion 32a on the film seal 30 side is combined with the hole 22a of the holding part vJshi2 with some play, it moves with a slight delay with respect to the sliding of the film seal 30. As a result of this movement, the toner cartridge 1 is sequentially peeled off from the lower surface of the lower frame 5.

Furthermore, when the upper and lower film seals of the present invention slide, the surface that is in contact with the toner of the own device when the toner cartridge is installed is caught between the upper and lower slide lids by the above-mentioned sliding action. As the film is moved in this manner, the dirty surfaces of the upper and lower film seals are exposed,
This prevents toner from spilling outside.

Then, the upper and lower slide lids and the film seal are slid, and the openings between the toner cartridge 1 and the toner hopper 40 are communicated with each other, so that the toner in the toner cartridge 1 is transferred to the toner hopper 40 through the opening. It will be supplied to

Then, return the slide lid to its original position, close the openings of both members, and insert the toner cartridge 1 into the toner hopper 4.
0 from the top of the toner to complete the toner replenishment process.

In the above-described embodiment of the present invention, the toner capacity of the toner cartridge 1 can be set arbitrarily, and for example, 1. For large copiers with a toner capacity of about 2009,
The device can be configured as a device having a capacity of about 5,009.

Furthermore, in the toner cartridge of the present invention, the sizes of the container body and the F frame can be set to the same standard size, and if the toner capacity is different, the height can be changed. It is.

In addition, in the toner cartridge of the present invention, the shape and structure of the holding member provided for the film seal can be arbitrarily set, and the structure of the connecting member is limited to the shape shown in the drawings. It is not limited to this, but any other configuration can be used.

(Effects of the Invention) Since the toner supply device of the present invention has the above-described configuration, slides of the same standard are installed on the toner hopper side of the developing device of the copying machine and on the frontage of the toner cartridge. Since a lid and a film seal are provided, the toner cartridge can be used in common even if the type of copying machine and the toner capacity of the toner cartridge are different.

Furthermore, in the toner replenishing device of the present invention, simply setting the toner cartridge in the upper part of the toner hopper allows
The film holding member that fixes the end of the film seal is surely engaged with the upper and lower sliding lids, and the film is thereby slid together with the lids, so that the openings of the upper and lower members are securely engaged. It is reliably formed, and the operation of replenishing toner can be easily performed through the opening, and since the part of the film that is in contact with the toner is not exposed, problems such as toner scattering do not occur. It will be possible to prevent this.

When the toner cartridge of the present invention is installed and the toner hopper is refilled with toner, the film can be peeled off relatively easily. Since a roller is provided on the sliding lid, it is possible to reduce the resistance of the film to the sliding lid.

Furthermore, when replenishing toner using the toner cartridge of the present invention, the surface of the film seal contaminated with toner is moved by the sliding of the slide lid so that they are aligned with each other, so that the surface adheres to the film seal. The collected toner is not exposed on the top of the toner popper or around it, and surrounding equipment, the operator's hands, etc. are prevented from getting dirty with the toner.
