After the developer supply container 1 rotates to the supply position, the locking by the locking member 7 is released, by which the rotation load applied to the second gear 6 is reduced, so that drive transmission, thereafter, to the feeding member 4 for developer supply is smooth.

No. 12/189,273, filed Aug. 11, 2008, which issued as U.S. Pat. No. 7,796,923, on Sep. 14, 2010, which is a divisional of U.S. patent application Ser.

TECHNICAL FIELD The present invention relates to a developer supply container for supplying a developer into a developer receiving apparatus. Examples of the developer receiving apparatus includes an image forming apparatus such as a copying machine, a facsimile machine, or a printer, an image forming unit detachably mountable to such an image forming apparatus.
BACKGROUND ART Conventionally, a developer (toner) in the form of fine powder is used for image formation in the image forming apparatus such as a copying machine and/or printer of an electrophotographic type. In such an image forming apparatus, the developer is supplied from a developer supply container exchangeably set in the image forming apparatus with consumption of the developer.
For example, Japanese Laid-open Patent Application Hei 7-199623 (U.S. Pat. No. 5,579,101) discloses a developer supply container having a coupling member for driving the feeding member therein. The coupling member of the developer supply container receives a driving force by engagement with a coupling member provided in the image forming apparatus side.
However, in the case of the structure of the developer supply container of Japanese Laid-open Patent Application Hei 7-199623 (U.S. Pat. No. 5,579,101), the rotating operation for the developer supply container is carried out by the user, and therefore, there is a possibility that following inconvenience may arise.
DISCLOSURE OF THE INVENTION Accordingly, it is an object of the present invention to provide a developer supply container having an improved operability.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional view illustrating a general arrangement of an image forming apparatus.
FIG. 7 is a perspective view illustrating a state when the development supply container is mounted to the developer receiving apparatus.
FIG. 14 is a perspective view of the developer supply container (a) according to the is present invention, a perspective view (b) illustrating an inside of the developer receiving apparatus, a sectional view (c) illustrating a release state, and a perspective view (d) of a locking member.
DETAILED DESCRIPTION OF THE INVENTION Examples of a developer supply container according to the present invention will be described. Various structures of the developer supply container may be replaced with other structures having the similar functions within the spirit of invention without particular a statement otherwise. The present invention is not intended to be limited to the structures of the developer supply container which will be described with the embodiments without a particular statement otherwise.
Embodiment 1 The structure of the image forming apparatus will first be described, and then, the structure of the developer supply container will be described.
One longitudinal end of the containing portion 10 a is provided with a drive gear member 12 as a driving member for transmitting a rotational driving force from a driving motor provided in the main assembly of the image forming apparatus 100. As will be described hereinafter, the drive gear member 12 applies, to the second gear 6, a rotating force in the same-direction as the rotating direction of the developer supply container for unsealing the developing device shutter, thereby to drive the feeding member 4.
The container body 1 a, as a portion of the developer supply container 1, in which developer is stored, is roughly cylindrical. The cylindrical wall of this container body 1 a is provided with a developer discharge opening 1 b, which is in the form of a slit which extends in the direction parallel to the lengthwise direction of the container body 1 a. It is desired that this container body 1 b is rigid enough to protect the developer therein and prevent the developer from leaking, before the developer supply container 1 is used for the first time, more specifically, during the shipment of the developer supply container 1. Thus, in this embodiment, the container body 1 a is formed of polystyrene by injection molding. Incidentally, the choice of the resinous substance to be used as the material for the container body 1 a does not need to be limited to polystyrene; other resinous substances, such as ABS, may be used.
The opposite end wall of the container body 1 a (in terms of lengthwise direction of container body 1) from where the first gear is attached is provided with an opening 1 c through which the container body 1 a is filled with developer. This opening is sealed with a sealing member (unshown) or the like after the filling of the container body 1 a with developer.
In the case of this structural arrangement, however, it, is possible that when a developer supply container 1, which has become depleted of developer, is replaced, a small amount of developer which is still remaining in the developer supply container 1 will come out of the developer discharge opening 1 b and scatter. Therefore, it is desired to provide the developer supply container 1 with the container shutter 3, as in this embodiment, so that the developer discharge opening 1 b can be resealed.
Referring to FIG. 3( b), the leading end portions (portions a in FIG. 3( b)) of the stirring wing 4 b are formed roughly in the shape of letter L. Thus, as the conveying member 4 is rotated, these portions a fall slightly behind the rest of the conveying member 4, nudging thereby the developer toward the developer discharge opening 1 b. In other words, the conveying member 4 also has the function of conveying the developer toward the developer discharge opening 1 b using these roughly L-shaped portions. In this embodiment, the stirring wing 4 b is formed of a sheet of polyester. Needless to say, the material for the stirring wings 4 b does not need to be limited to a sheet of polyester; other resinous substances may be employed, as long as a sheet formed of a selected substance is flexible.
The sealing projection if is for pushing up the developing device shutter 11 (FIG. 6) to seal the developer receiving opening 10 b (FIG. 6) during the developer supply container removal operation (which is for reversely rotating developer supply container by preset angle from its operative position (replenishment position) to position into which developer supply container is mountable, or from which developer supply container is dismountable).
In order to cause the developing device shutter 11 to be opened or closed by the operation for rotating the developer supply container 1, the positional relationship between the unsealing projection 1 e and sealing projection if are set as follows:
That is, they are positioned so that when the developer supply container 1 is in the proper position in the developer receiving device 10 (FIG. 6), the unsealing projection 1 e is on the upstream side of the developing device shutter 11 in terms of the direction in which the developing device shutter 11 is opened, and the sealing projection if is on the downstream side.
In this embodiment, the developer supply container 1 and developer receiving device 10 are structured so that the developing device shutter 11 is opened or closed with the use of the unsealing projection 1 e and sealing projection 1 f. However, they may be structured as shown in FIG. 21.
Also in this embodiment, after the mounting of the developer supply container 1, the developer supply container 1 is to be rotated by the preset angle into its operative position (replenishment position), with the use of the handle 2. Prior to this setup operation, the drive transmitting means and driving gear member 12 are not in engagement with each other (disengaged state); there is a certain amount of distance between the two in terms of the circumferential direction of the developer supply container 1. Then, as the developer supply container 1 is rotated with the use of the handle 2, the drive transmitting means and the driving gear member 12 meet and engage with each other (engaged state).
As described above, the position of the second gear 6 relative to the developer supply container 1 (relative to unsealing projection 1 e or developer discharge opening 1 b), in terms of the circumferential direction of the container body 1 a is adjusted so that the second gear 6 and driving gear member 12 begin to mesh with each other at the abovementioned time to transmit driving force. Therefore, the second gear 6 and first gear 5 are attached to the container body 1 a so that they are different in the position of their rotational axes.
Referring to FIG. 4, the first gear 5 is provided with a locking member 9, as a suppressing means (means for increasing rotational load), which is in the form of a ring and is fitted in the groove 5 b with which the peripheral surface 5 c of the first gear 5 is provided. The locking member 9 is enabled to rotate relative to the first gear 5 about the rotational axis of the first gear 5. The entirety of the outer circumferential portion of the locking member 9 constitutes a hooking (catching) portion 9 a, which is made up of multiple teeth like the teeth of a saw.
Next, referring to FIGS. 7-9, the operation for setting up the developer supply container 1 will be described. FIGS. 8( b) and 9(b) are sectional views of the developer supply container 1 and developer receiving device 10, which are for describing, the relationship among the developer discharge opening 1 b, developer receiving opening 10 b, and developing device shutter 11. FIGS. 8( c) and 9(c) are sectional views of the developer supply container 1 and developer receiving device 10, which are for describing the relationship among the driving gear member 12, first gear 5, and second gear 6. FIGS. 8( d) and 9(d) are sectional views of the developer supply container 1 and developer receiving device 10, which are for describing primarily the relationship among the developing device shutter 11 and the portions of the container body 1 a, which move with the developing device shutter 11.
FIG. 10( b) shows the developer supply container 1 which has been rotated by the preset angle by the user. When the developer supply container 1 is in the condition shown in FIG. 10( b), the developer discharge opening 1 b is practically entirely covered with the container shutter 3 (leading edge of developer discharge opening 1 b is opposing container shutter stopper portion 10 d of developer receiving opening 10). The developer receiving opening 10 b is also completely closed by the developing device shutter 11, making it impossible for the developer receiving device 10 from being supplied with developer
Further, in this step, the operation for rotating the developer supply container 1 and the operation for opening the developing device shutter 11 are coordinately carried out by the unsealing projection 1 e. More concretely, as the container body 1 a is rotated, the developing device shutter 11 is pushed down by the unsealing projection 1 e of the developer supply container 1, being thereby slid in the direction to unseal the developer receiving opening 10 b. As a result, the developer receiving opening 10 b is unsealed (FIGS. 8( d)-9(d)).
In this step, the developing device shutter 11 is moved again by being pushed up by the sealing projection if of the developer supply container 1, and the developer discharge opening 1 b rotates, being thereby resealed by the container shutter 3 (FIG. 9( b)-FIG. 8( b)).
Thereafter, the user is to place a brand-new developer supply container (1) prepared in advance into the developer receiving device 10. This operation for mounting the brand-new developer supply container (1) is the same as the above described �Operation for Setting up Developer Supply Container�.
Next, referring to FIG. 12, the principle of the model shown in FIG. 12, will be described in detail. In the drawing, �a, b, and c� stand for the radii of the pitch circles of the driving gear member 12, second gear 6, and first gear 5, respectively. �A, B, and C� stand for the rotational loads of the driving gear member 12, second gear 6, and first gear 5 at their rotational axes, respectively (A, B, and C also designate the axial lines of these gears, respective, shown in FIG. 12). �E� stands for the force necessary to pull in the developer supply container 1 after the second gear 6 meshes with the driving gear member 12, and �D� stands for the resistive torque at the rotational axis of the container body 1 a. In order for the container body 1 a to be rotated, f>F, and F=D/(b+c), f=(c+2b)/(c+b)�E=(c+2b)/(c+b)�(C/c+B/b),
Therefore, (c+2b)/(c+b)�(C/c+B/b)>D/(b+c), and (C/c+B/b)>D/(c+2b).
Amount of torque necessary to rotate second gear 6=F′�d′�D′/(2�(2e+d′)).
The rotational resistance F′ of the developer supply container 1 is affected by the diameter of the developer supply container 1, size of sealing surface of the sealing member, and structure of sealing member. However, it is reasonable to think that an ordinary developer supply container is roughly 30 mm-200 mm in diameter. Accordingly, the rotational resistance F′ is set to a value within the range of 1 N-200 N. Further, in consideration of the diameter of the developer supply container 1, the diameter d′ and amount of eccentricity e of the second gear 6 should be in the range of 4 mm-100 mm, and the range of 4 mm-100 mm, respectively. Needless to say, optimal values are to be selected according to the size and specifications of an image forming apparatus. Thus, in the case of an ordinary developer supply container 1, the amount of torque required to rotate the second gear 6 is set to a value within the range of 3.0�10−4 N�m-18.5 N�m, in consideration of the MIN and MAX of the abovementioned ranges.
Therefore, if the amount of eccentricity and diameter of second gear 6 are 20 mm and 20 mm, respectively, in this embodiment, it is desired that the amount of torque required to rotate the second gear 6 is set to be no less than 0.05 N�m and no more than 1 N�m, in consideration of the rotational resistance F′. Further, in consideration of various losses, the amount of deviation in the measurements of the components, margin of safety, etc., which will be described later, the top limit value is desired to be roughly 0.5 N�m in consideration of the strength of the torque generating mechanism of the developer supply container 1. That is, the amount of torque required to rotate the second gear 6 is set to be no less than 0.1 N�m and no more than 0.5 N�m.
In this embodiment, the image forming apparatus is structured so that the rotational load for the second gear 6, including the amount (roughly 0.05 N�m) of torque necessary to stir the developer in the developer supply container 1, is set to be no less than 0.15 N�m and no more than 0.34 N�m, in consideration of the nonuniformity in the various components. However, the amount of torque necessary to stir the developer is affected by the amount of developer in the developer supply container 1 and the structural setup for stirring the developer. Therefore, the rotational load for the second gear 6 should be set in anticipation of this change.
In this embodiment, after the disengagement of the locking mechanism, the rotational load of the second gear 6 is roughly 0.05 N m, which is the same as the amount of torque necessary to rotate the conveying member 4 to stir the developer.
In consideration of the amount of load to which the developer supply container 1 is subjected and the amount of power consumption, the amount of this torque necessary to rotate the second gear 6 after the disengagement of the locking mechanism is desired to be as small as possible. Further, assuming that an image forming apparatus is structured as in this embodiment, if the amount by which the torque generating mechanism contributes to the rotational load of the second gear 6 is no less than 0.05 N�m after the disengagement of the locking mechanism, heat is generated in the torque generating portion, and as this heat accumulates, it is possible that it will affect the developer in the developer supply container 1 by transmitting thereto.
Therefore, it is desired that an image forming apparatus be structured so that the amount by which the torque generating mechanism contributes to the rotational load of the second gear 6 after the disengagement of the torque generating means is no more than 0.05 N�m.
Referring to FIG. 12, this factor will be concretely described. The amount f of the rotational force generated in the shaft portion of the second gear 6 is equivalent to a component of the amount of the force F which the second gear 6 receives from the driving gear member 12. Therefore, it is possible that the rotational force f will not be generated, because of the positional relationship between the second gear 6 and driving gear member 12. In the case of the model shown in FIG. 12, the straight line connecting the point C, or the rotational axis of the container body 1 a (which in this embodiment coincides with rotational axis of first gear 5), and the point B, or the rotational axis of the second gear 6, is the referential line. It is desired that the image forming apparatus be structured so that the angle θ (clockwise angle relative to referential line (0�)) between this referential line and the straight line connecting the point B, and the point A, or the rotational axis of the driving gear member 12, is no less than 90� and no more than 250�.
In particular, it is desired that the f component (component generated at the contact point between the second gear 6 and driving gear member 12, and parallel to line tangential to container body 1 a) of the force E generated by the meshing between the second gear 6 and driving gear member 12 be efficiently utilized. Thus, the angle θ is desired to be set to be no less than 120� and no more than 240�. Incidentally, from the standpoint of more effectively utilize the component f of the force E, the angle θ is desired to be set to be close to 180�. In this model, it is 180�.
In this embodiment, each of the above-mentioned gears was positioned in consideration of the above described factors.
The material for each of the above-mentioned components, the method for forming each of the components, the shape of each component, etc., do not need to be limited to those mentioned above. They are optional; they can be modified within a range in which the above described effects are obtainable.
Embodiment 2 Embodiment 2 will be described. This example is different from embodiment 1 in the structure of a driver transmission means for the developer supply container. The other structures of this embodiment are similar to those of embodiment 1, and therefore, the detailed description thereof is omitted.
Embodiment 3 Embodiment 3 will be described. This example is different from embodiment 1 in the structure of a driver transmission means for the developer supply container. The other structures of this embodiment are similar to those of embodiment 1, and therefore, the detailed description thereof is omitted.
Embodiment 4 Embodiment 4 will be described. This example is different from embodiment 1 in the structure of a driver transmission means for the developer supply container. The other structures of this embodiment are similar to those of embodiment 1, and therefore, the detailed description thereof is omitted.
Embodiment 5 Referring to FIG. 23, a developer supply container 1 according to embodiment 5 will be described. The structure of the container of this embodiment is fundamentally the same as that of embodiment 1, and therefore, the description will be made as to the structure different from that of embodiment 1. The same reference numerals are assigned to the elements having the corresponding functions.
More concretely, the first gear 5 is provided with a projection 5 d as a suppressing means (rotational load switching means), whereas the container body 1 a is provided with a hole 1 j as a suppressing means (rotational load switching means). The projection 5 d is on the side of the first gear 5, which contacts the container body 1 a, and the hole 1 j is on the side of the container body 1 a, which contacts the first gear 5.
Further, in the case of this structural arrangement, driving force is continuously inputted into the driving gear member 12 even after the completion of the automatic rotation of the developer supply container 1. Thus, the strength of the projection 5 c is set so that the projection 5 c will be broken by the driving force inputted to the driving gear member 12 after the completion of the automatic rotation of the developer supply container 1. Thus, after the completion of the automatic rotation of the developer supply container 1, the projection 5 c is broken, allowing thereby the first gear 5 to rotate relative to the container body 1 a. Incidentally, in this embodiment, the rotational load for the second gear 6 is set to 0.3 N�m, and the projection 5 c is designed so that it breaks off as the amount of torque transmitted to the second gear 6 reaches 0.6 N�m.
More concretely, the torque generating mechanism is provided with the ring 14 as a suppressing means, which is placed, in the compressed state, between the peripheral surface 5 a of the first gear 5 and one of the lengthwise end walls 1 m of the container body 1 a. Further, the ring 14 is locked to the peripheral surface 5 a of the first gear 5. In this embodiment, the ring 14 is formed of a substance which is substantially stronger than the substance used as the material of the ring 14 in the first embodiment. The rotational load is generated by the friction which occurs as the lengthwise end wall 1 m of the container body 1 a and compressed ring 14 slide against each other.
Embodiment 6 Referring to FIG. 24, a developer supply container 1 according to embodiment 6 will be described. The structure of the container of this embodiment is fundamentally the same as that of embodiment 1, and therefore, the description will be made as to the structure different from that of embodiment 1. The same reference numerals are assigned to the elements having the corresponding functions.
Embodiment 7 Referring to FIG. 26, a developer supply container 1 according to embodiment 7 will be described. The structure of the container of this embodiment is fundamentally the same as that of embodiment 1, and therefore, the description will be made as to the structure different from that of embodiment 1. The same reference numerals are assigned to the elements having the corresponding functions.
In this embodiment, the first gear 5 is kept completely locked. However, the developer supply container 1 may be structured so that the first gear 5 is rotatable as long as the rotational force applied to the first gear 5 is greater than a preset value. In such a case, the locking member 7 is disengaged from the locking member 9 by the disengaging projection of the locking member 9 which rotates with the first gear 5 relative to the container body 1, after the completion of the automatic rotation of the developer supply container 1. Therefore, the developer discharge opening 1 b can be properly connected with the developer receiving opening 10 b. Embodiment 8 Referring to FIG. 27, a developer supply container 1 according to embodiment 8 will be described. The structure of the container of this embodiment is fundamentally the same as that of embodiment 1, and therefore, the description will be made as to the structure different from that of embodiment 1. The same reference numerals are assigned to the elements having the corresponding functions.
Incidentally, the first gear 5 is kept completely locked. However, the developer supply container 1 may be structured so that the first gear 5 is provided with a certain amount of rotational load instead of being completely locked. In such a case, the locking member 7 is freed from the locking member 9 by the disengaging projection of the locking member 9 which rotates with the first gear 5 relative to the container body 1, after the completion of the automatic rotation of the developer supply container 1. Therefore, the developer discharge opening 1 b can be properly connected with the developer receiving opening 10 b. Embodiment 9 Referring to FIG. 28-FIG. 31, the developer supply container 1 the Embodiment 9 will be described.
INDUSTRIAL APPLICABILITY According to the present invention, an operability of the developer supply container can be improved. A structure for improving the operability of the developer supply container can be simplified.
