In the embodiment, an upper frame and a lower frame that are respectively manufactured by molding by injection of high impact polystyrene, are joined together by means of vibration sounding. On the other hand, the feeder member 2 functions to feed the pigment housed in the main body IA towards the pigment supplying port lg. The member Feeder 2 includes, as shown in FIG. 5, a shaft portion 2A, and a rigid helical feeder blade 2B at the shaft portion 2A that functions as a feeder portion for feeding the powder pigment in a predetermined direction by rotation of the powder. the portion of axis 2A. The feeder member 2 is mounted to the main body 1A of the container with the axis of the shaft portion 2A substantially coaxial with the center of the pigment supplying port lg. The feeder member 2 is not limited to a type called screw of this mode, but can be a flexible blade mounted on the shaft portion 2A, for example. The shaft portion and the blades must be molded in an integrated manner. In this embodiment, the shaft portion 2A and the blade 2B are made of plastic resin material and are molded in an integrated manner. In this embodiment, the feeder member 2 includes an extension portion 2C that extends to the portion of the cylinder of the serving portion of pigment la. In this embodiment, the extension portion 2C projects outwardly from the portion of the pigment supplying port IA. The free end portion of the extension portion 2C projected outwardly receives rotational force from the main unit 100 of the apparatus. To achieve this, the free end portion is provided with an obturating member 3 that moves in the direction of the axis.
As will be described in more detail below, the sealing member 3 has 4 functions of this mode. More specifically, the four functions are: (1) to seal the portion of the pigment supplying port; (2) receive the rotational force transmitted from the main unit 100; (3) transmitting the rotation force towards the feeder member 3; and (4) connecting with a coupling member 6 provided in the main unit of the apparatus for opening and closing the portion of the pigment supplying port. The driving force received by the sealing member 3 of the main unit 100 is transmitted to the shaft portion 2A by the spreading portion 2C to rotate the feeder member 2. The end portion 2A of the spreading portion 2C has a configuration that can receive the rotational force by the sealing member 3 from the main unit 100, and in this embodiment has a shape of H. The end portion of the shaft portion 2A is supported by a sealing member 3 by an end portion 2a of the spreading portion 2 C. The other end portion 2b of the shaft portion 2A is rotatably coupled to a receiving portion 2b of the main body IA of the container, so that the feeder member 2 rotates when the container is not sealed.
The feeder member 2 is supported by the sealing member 3 in such a way that the feeder blade 2B is out of contact with the surface of the internal wall lal of the serving port portion of the pigment la, and this portion of axis 2a and the surface of the inner wall of the portion of the pigment supply port are substantially horizontal. With the support of the feeder member 2 in this form, the pigment can be fed in the substantially horizontal direction towards the pigment supplying port lg when the feeder member 2 is rotated. If the fine particles of the pigment are introduced between the surface of the The inner wall of the serving portion of the pigment supply port and the feeder blade 2b and these are rubbed, the pigment can be fused to the surface of the internal wall lal or it is possible that aggregates of the pigment are formed. This can be avoided. The feeder member 2 can preferably be manufactured by injection molding or the like from a plastic resin material, as described, but another method or material is usable. This can be divided into a plurality of parts that are manufactured separately, and then joined together. With reference to Figure 6 the sealing member 3 will be described. In Figure 6, (A) is a front view of the obturator member; (B) is a perspective view seen in the direction A in (A); (C) is a view in the direction D in (A); and (D) is a front view in section. In (A) - (D) of Figure 6, designated 3b, there is an obturating section, provided on its side closest to the pigment supply container, for sealing so that the pigment port Ig of the container can be opened. Pigment supplier 1. The external diameter of the sealing portion 3b is much larger than the internal diameter of the pigment supplying port Ig. Thus, the sealing member 3 is sealed to the pigment supplying port lg by pressure fitting the coupling portion 3bl of the sealing portion 3b in the portion of the pigment supplying port through the pigment supplying port Ig. Designated by 3c is a clutch portion that functions as a portion receiving the driving force to receive the driving force to rotate the feeder member 2 from the main unit 100 of the apparatus when the pigment supply container 1 is mounted in the unit main 100. The clutch portion 3c is provided with a projected portion 3cl extended in the direction coaxial with the axis portion 2a of the feeder member 2 in the direction away from the main body ÍA of the sealing portion 3b (when the sealing member 3 is mounted to the main body 1A of the container). The clutch portion 3c is provided with projection of elongated ridges (ribs) 3d on the peripheral surface of the projected portion 3cl, whose projections function as a portion receiving the engagable drive force with the coupling member 4. In this embodiment, four of these striae projections are provided at the same distance and in the circumferential direction. # Obturating member 3 is provided with a clutch hole 3a which functions as a transmitting portion of the driving force to transmit, to the feeding member 2, the driving force from the main unit 100 by coupling with an end portion 2a to the feeder member 2 and the clutch hole 3a is in the form of an opening (hole) formed in the sealing portion 3b and the clutch portion 3c. The clutch hole 3a is H-shaped corresponding to the shape H of the end of the shaft 2a of the feeder member 2 projected from the powder pigment supplying portion, and is slightly larger than the end of axis 2a. By this, the end of the shaft 2a engages loosely with the clutch hole 3a. By the end of the shaft 2a loosely coupled with the clutch hole 3a, the feeder member 2 and the The sealing member 3 is interconnected in the direction of rotation of the feeder member 2, while moving relative to one another in the thrust direction. Thus, the sealing member 3 can be separated from the main body IA of the container when the pigment supply container is mounted to the main unit, as will be described below, so as to achieve the separation of the shutter (opening) from the supplying port of the container. pigment powder lg. The length of the coupling between the end of the shaft 2A and the coupling hole 3a is quite long to prevent disengagement between the sealing member 3 and the main body IA of the container when the sealing member 3 moves away from the main body. Therefore, even if the sealing member 3 moves away from the main body IA of the container, the feeding member 2 can receive the driving force by the sealing member 3 (clutch portion 3C). Between the clutch portion 3c and the sealing portion 3b, a flange portion 3f is provided which is connected to the end of the port for supplying pigment when the sealing portion 3b is press fit into the port la. The external diameter of the flange portion is substantially equal to the outer diameter of the portion of the pigment supplying port. By means of the flange portion 3f, the sealing portion 3b is snapped into the portion of the pigment supplying port through a distance corresponding to the length of the coupling portion 3bl. Designated by 3e is a blocking projection 3q which functions as a blocking portion which is formed at one end of a clutch portion and which is to be engaged with the blocking member 6 in the main unit 100 (FIG. 5) and by the coupling between the block projection 3e and the blocking member 6, the sealing member 3 can be fixed when the shutter is removed from the powder pig supplying port lg. The sealing member 3 having this structure can preferably be manufactured by injection molding a resinous material or the like, but another method and / or material is usable. The sealing member 3 is required to have a suitable elasticity for snapping in the supplying port of the pigment and sealing the port. The material of preference is a low density polyethylene, and other usable examples include polypropylene, high density polyethylene or the like. A method of assembling the pigment supply container 1 will be described below. In the method of assembling the pigment supply container 1, the feeder member 2 is inserted into the lower portion of the main body IA of the container through the pigment supplying port lg (Figure 5). Then, the predetermined amount of pigment (not shown) is filled in the main body IA and finally, the pigment supplying port lg is sealed by a sealing member 3, whereby the container supplying the pigment 1 is obtained. this way, the assembly of the pigment supply container 1 of this # modality is very simple and easy, and there are very few steps of manufacture. The pigment can be filled through the pigment supplying port lg; otherwise, a port for the filling of the additional pigment (not shown) can be formed in a suitable portion of the main body. container, and the pigment can be filled through the pigment filling port, which is then clogged. Another alternative form, the main body IA of the container can be divided into two or more parts, which are joined together after the pigment is filled. Where the supplying port of pigment Ig of the main body IA formed integrally also a filling port is used, no additional cover or joining step after filling is necessary. In the serving portion of pigment supplier , the feeder member 2 extends, and therefore, it is preferable that it has a size sufficient to allow uniform discharge of the pigment. The description will be made as the ratio of the cross-sectional area of the portion of the pigment-supplying port la and the cross-sectional area of the passage portion (axis portion 2A) of the feeder member 2. The cross-sectional area of the portion of the pigment-supplying port preferably, it is not less than twice the cross-sectional area of the shaft portion 2a of the member $ Feeder 2, in addition to preference, is not less than three times, and still further preferred not less than five times. In this mode it is approximately 3 times. In this mode, the portion of the pigment supplying port is cylindrical, and therefore, the internal diameter of the portion of the pigment supplying port is approximately 3 times the outer diameter of the shaft portion 2A of the feeder member 2. On the other hand, if the inner diameter of the portion of the pigment supplying port is too large, the pigment contamination around the port The supplier of pigment lg is significant, and it may be difficult to maintain the tightness during transportation or in the case of change of environmental condition. Therefore, the internal diameter of the portion of the pigment supplying port is preferably not greater of 40 mm. In this mode it is approximately 24 mm.
The description will be made for an exchange method of the pigment supply container. When the pigment in the container supplying the pigment 1 is completely consumed with the image formations, the detecting means of the empty pigment supply container (not shown) provided in the main unit 100 of the apparatus detects it, and shows the event to the user in the presentation medium 100b (FIG. 2) such as a liquid crystal display. In this embodiment, the container supplying the pigment 1 is exchanged by the user by the following steps. As shown in (A) and (B) of Figures 2 to 7, the cover 15 which is in this closed moment, is opens by rotating it around hinge 18 to a position as shown in figure (C). The main body IA is moved by means of the opening means of the supply portion of the pigment, which will be described later, in interrelation with the hole of the cover 15, and the sealing member 3 (Figure 9) which is in the open position away from the main body IA to open the pigment supplying port lg, is snapped into the portion of the pigment supplying port whereby the supplying port of pigment lg closes (figure 8).
The user removes the container supplying the pigment 1, which now does not contain the pigment, from the main unit 100 in the opposite direction of the direction indicated by the arrow in (C), to remove it from the main unit 100. After this, the user inserts the new pigment supply container 1 into the main unit 100 in the direction of the arrow, and then closes the cover 15 ((A) and b)). In the interrelation with the action of * closure of the cover 15 the sealing member 3 is separated from the main body of the container by the opening means of the pigment supply portion, thereby opening the pigment supplying port lg. In this way, the pigment supply container is exchanged. With regard to figures 8 and 9, the Description according to the opening and closing operation of the pigment supplying port lg which interrelates with the opening and closing operation of the cover 15. The structures in the following description are provided in the main unit 100 of the apparatus. In figures 8 and 9, designated by 6 is a blocking member that functions as locking means for locking the sealing member 3 by engagement with the locking projection 3e of the clutch portion 3c. Designated by 57 there is a support table that has the blocking member 6 mounted thereto, and the support table 57 is rotatable about an axis of rotation 57a, and is pushed in the clockwise direction by the push member 58. Designated by 59 there is a retainer for positioning of the support table 57. i Designated for 60 s finds a sliding table that slides by means of a rotary roller 63. Designated by 51 is a carrier member of the container provided on the sliding table 60, and the carrier member of the container 51 is rotary around the center of rotation 51a, is pushed in the direction counterclockwise by a spring 52. Designated by 53 is a retainer for the placement of the carrier member of the container 51. The member that moves the container providing the pigment is constituted by a member carrying the container 51 and the sliding table 60. The means for opening and closing the pigment supplying port is constituted by the carrying member of the rec 51, the slide table 61 and the blocking member 6. On the other hand, the carrier member of the container 51 is provided with a locking portion 51c to block the clutch projection from the main body of the container. When the clutch projection advances in the direction indicated by the arrow C as shown in figure 8, with the insertion of the container supplying the pigment 1 in the main unit 100 of the apparatus, the carrier member of the container 51 rotates against the force of the container 52 in the direction of the arrow B. When the clutch projection is inserted into the block portion 51c, the carrier member 51 returns by the spring force of the spring 52 to block the clutch projection le. When the carrier member 51 blocks the clutch projection, the container supplying the pigment 1 is moved by the sliding table 60 in the directions of assembly and disassembly (arrows A and B in figures 7, 8). Designated by 54 is a sliding axis which is supported by the support means (not shown) for the sliding movement in the direction of the axis. The sliding shaft 54 is pushed in the direction away from the table support 57 (downward direction in Figure 8) as indicated by the arrow A by the push member (not shown). The position of this is determined by the shaft seal 55. Designated by 56 is a blocking member mounted to the sliding shaft 54. When the sliding shaft 54 slides in the direction of the support table 57 as indicated by the arrow B, the blocking member 56 is brought into engagement with the rib portion 51e of the carrier member of the container. .51 to block the carrier member of the container 51. The direction of the arrow A is the direction of disassembly of the supply container 1 of the main unit 100 of the apparatus, and the direction of the arrow B is the mounting direction thereof to the main unit of the apparatus. The sliding table 60 is provided with a projection 60a formed therein. The projection 60a engages with an elongated hole 61b formed in an end portion of the oscillating arm 61 that oscillates about the oscillating shaft 61a. The oscillating arm 61 is pushed in the clockwise direction by the elastic force of the pushing member 62, and is placed by the stop 64. The other end portion of the oscillating arm 61 is provided with a slot portion 61b having an open end. The cover 15 is provided with a projection 15b which enters the slot portion 61d when the cover 15 is closed. By the projection 15b entering the slot portion 61d, the oscillating arm 61 oscillates counter-clockwise against the force Elastic of the push member 62 in interrelation with the closing operation of the cover 15. The cover 15 for exchange is provided with a wall portion 15a which is connected to an end portion 54a of the slide shaft 54 when it is closed. Through the wall portion 15a, the sliding shaft 54 slides in the direction of the arrow B in interrelation with the closing operation of the cover 15. By sliding the sliding shaft 54 in this manner, the other end 54b of the sliding shaft 54 is in abutting contact with 5 the projection 57b of the support table 57. By this, the support table 57 and the blocking member 6 rotate against the elastic force of the pushing member 58, whereby the blocking member 6 blocks the blocking projection 3e of the • sealing member 3. 10 With these structures, when the pigment supply container 1 is inserted into the main unit 100 of the apparatus, as shown in (C) of Figure 7, the clutch projection of the main body of the container is moves in the direction of arrow C shown in the figure 8. After this, the clutch projection 1C is blocked with the blocking portion 51c of the container carrying member 51, and the fresh or new pigment supply container 2 is mounted on the main unit 100 in this condition. In other words, the supplier container of Pigment 1 is correctly placed in the main unit 100 of the apparatus by means of the clutch projection 1C. After the pigment supply container 1 is installed in this manner, the cover 15 is closed, and by this, the wall portion 15a of the cover 15 is splices with an end portion 54a of the sliding shaft 54, of 54, so that the sliding shaft 54 slides in the direction of the arrow B. After this, the other end 54b of the sliding shaft 64 is connected with the projection 57b of the support table 57. By this, the support table 57 and the blocking member 6 are rotated against the elastic force of the pushing member 58, by which the blocking member 6 blocks the blocking projection 3e of the sealing member 3 . ^ He The blocking member 56 of the sliding shaft 54 is moves towards the carrier member of the container 51 with the sliding movement of the sliding shaft 54 and engages with the rib portion 51e of the container carrying member. By doing this, the carrier member of the container 51 is blocked. When the cover 15 is closed in a predetermined position, the projection 15b of the cover 15 enters the slot portion 61d of the oscillating arm 61 to oscillate the oscillating arm 61 counter-clockwise against the elastic force of the projection 15b.
By oscillating the oscillating arm 61, the sliding table 60 slides in the direction of the arrow A. By this, the pigment-supplying container 1 that blocks with the carrier member of the container 51 in the clutch projection is also slide in it address.
When the supplying container 1 moves in the direction of the arrow A, the sealing member 3 is blocked with the blocking member 6 so that it is impossible to move it in the direction of the arrow A. Therefore, the main body of the container it is separated from the sealing member 3, thereby opening the pigment supplying port lg, as shown in figure 9. The portion of the pigment supplying port, as shown in figure 5, is maintained by the support 5 of the main unit 100 with the outer periphery sealed with an annular sealing member 7. Thus, when the supplying container 1 is mounted to the main unit 100, the position of this is determined by the clutch projection 1C and the portion of the supplying port of pigment In this embodiment, the sealing member 3 is supported in a position remote from the supplying port of pigment Ig. By doing this, it can be kept at a distance necessary to allow uniform discharge of the pigment, depending on the coagulation property of the pigment. In this way it is possible to avoid obstruction of the adjacent discharge outlet and various problems resulting therefrom. On the other hand, when the user opens the cover 15 after the pigment in the container supplying the pigment 1 has been consumed substantially completely, the projection 15b of the cover 15 moves from the position shown in Figure 9 until butt contact with the wall portion 61c of the oscillating arm 61 to oscillate the oscillating arm 61 in the clockwise direction. Then, the sliding table 61 slides in the direction of the arrow B and the container supplying the pigment 1 slides in the same direction. At this time the carrier member of the container 51 receives a force in the clockwise direction from the clutch projection of the pigment supply container. However, since the blocking member 56 blocks the rotation of the container carrying member 51, the clutch projection is prevented from disengaging from the carrier member of the container 51. Therefore, the container supplying the pigment 1 slides to the supplying port of the container. lg pigment in abutting contact with the flange portion 3f of the sealing member 3, whereby the pigment supplying port Ig is closed. Then, the cover 15 further opens, the sliding shaft 54 is moved to a predetermined position by the retainer of the shaft 55 since it is pushed in the direction of the arrow A by the pushing means as described above. With this, the sealing means 6 rotates in the clockwise direction to move the sealing member 3 away. Therefore, the sealing member 3 is released by means of the blocking member 6. The carrier member of the container 51 is released from the blocking of the container. blocking member 56. With this state, the pigment supply container 1 is removable from the main unit 100. Then the pigment 1 supplying container can be separated by pulling it in the direction of the arrow A. By applying the force of drag in the direction of arrow A, blocking the clutch projection will # released by the container carrying member 51. As described above, when the pigment supply container 1 is installed in the main unit 100, the blocking projection 3e of the sealing member 3 is blocked by the blocking member 6 and is supported far from the container port of pigment Ig of the container supplier of the pigment. At this time the clutch ratio in the direction of rotation between the sealing member 3 and the feeder member 2 is maintained. Therefore, by rotation received by the sealing member 3 from the main unit 100, the member feeder 2 rotates to gradually supply the pigment to the main unit 100 through the pigment supplying port lg. In the embodiment, the pigment detector 201g is provided in the pigment hopper. When the detector 201g detects that there is no pigment, the sealing member 3 tour. When the when detector 201g detects the presence of pigment, rotation of the sealing member is stopped. In this way, the sealing member 3 rotates intermittently according to the consumption of the pigment in the main unit 100, so that the pigment is supplied intermittently and gradually to the main unit 100. However, it is possible to supply all the pigment to the main unit 100 when the pigment supply container 1 is installed in the main unit 100. On the other hand, when the pigment supply container 1 is installed in the main unit, the clutch portion 3c of the sealing member 3, as shown in figure 5, it engages with the coupling member 4 of the main unit 100. The coupling member 4 functions to transmit, to the sealing member 3, the driving force of the driving device (not shown) provided in the main unit 100. Figure 10 shows in detail the coupling member, wherein (A) is a front view of the coupling member, and (B) is a rear side view, and (C) ) is a sectional side view. In Figure 10, designated by 4a is a gear portion formed on the outer surface of the coupling member 4. This receives the driving force from the side of the main unit 100 through the gear portion 4a.
Designated by 4b is a receiving hole for receiving the sealing member 3, and this is formed in the center of the coupling member 4. The inner surface of the hole 4b is provided with a clutch groove 4c for coupling with the spline projections 3d of the sealing member 3. The end of the hole 4b opposite the container supplying the pigment 1 is provided with a guide portion of decreasing section 4d. In this embodiment, 4 of the 3d groove projections are formed on the external curved surface of the sealing member 3, with the same distance. In addition, twelve clutch slots 4c are formed in the coupling member 4. The number of clutch slots 4c is greater than the number of the 3d projections, and the guide portions 4d are provided, so that, when the container supplying the Pigment is installed in the main unit, these can be coupled safely even if there is a phase difference between the 3d spline projections and the clutch slots 4c. The number of the 3d projections of the sealing member 3 is not limited to 4, but can be suitably selected by one skilled in the art. The same applies to the number of clutch slots 4c, and is not limited to 12. The description of the pigment discharge will be made. The coupling member 4 receives the rotation force through the pulse transmitting means (not shown) such as the gear or the like from the power source (not shown) such as an engine or the like, of the main unit 100. The driving force is transmitted to the sealing member 3 by the coupling between the 3d groove projection and the clutch groove 4c, and is transmitted to the feeder member 2 through the coupling between the free H-shaped end 2a and the H-shaped clutch hole 3a. In this embodiment, the rotation speed of the feeder member 2 is 25 rotations per minute. When the feeder member 2 rotates, the pigment lodged in the main body IA of the container is fed to the pigment supplying port Ig, and thereafter, it drops from the pigment supplying port lg to the pigment hopper 201a through the port pigment receiver 9 of the main unit 100. The portion from the pigment supplying port lg to the pigment receiving port 9 is hermetically sealed by means of the sealing member 7, as already described and, therefore, the pigment is prevented from discharged from the Ig pigment supply port leaks out or disperses. A rotating sliding portion exists in a portion where the sealing member 3 and the main unit 100 make contact, but the portion is far from the portion of the pigment supplying port, and therefore, does not directly contact the pigment, so which does not cause coagulation of the pigment or the like. The position of the rotating sliding portion can be away from the portion of the pigment supplying port by a suitable distance according to the pigment fluidity, the feeding force of the feeder member 2, the speed of discharge of the pigment. The present invention is not limited to any of the details of the first embodiment. For example, the disengagement method of the sealing member 3 may be such that the main body side A is moving while the sealing member 3 is fixed, or it may be such that the sealing member 3 is moved while the main body is moving. of the container is fixed. However, the sealing member 3 receives a rotational force from the main unit 100, as described above. Therefore, when the sealing member 3 moves while the main body of the container is fixed, the mechanism is more complicated and, therefore, the fixed sealing member 3 is preferred. The rotation speed of the feeder member 3 is suitably selected by a person skilled in the art, according to the amount of feed of the pigment, but if it is too high, the charges of the driving source of the main unit 100 or the mechanism of impulse transmission is increased, if it is too low the pigment can not be fed in a sufficient amount. Preferably it is 3-100 rotations per minute, more preferably 5-50 rotations per minute. The configuration of the main body IA of the container can be any if space can be used efficiently, and the size in the capacity of the pigment container can be suitably selected by a person skilled in the art. Even if the amount ofThe pigment is as large as about 2 kg, for example, what rotates is only the feeder member 2, and therefore, the torque of the required rotation is as small as 2-3 kgf-cm. The sealing member 3 is adjusted by pressure in the pigment supplying portion, but is can use a sealing member to seal the portion, or a threaded portion corresponding to the main body IA and the sealing member 3 can be used to seal the portion. In the first mode, the feeder element of the feeder member 2 is of a helical shape having a high feed force, but the helical shape is not inevitable. For example, as shown in Figure 11, (A), a blade portion 2aB in the form of a film as a feeder element can be installed in the axis portion 2A. In this case, the pigment is discharged F using the pigment fluidity. As shown in Fig. 11, (B), the blade portion 2Ba can be provided with a window 2B1 by which the moment of torque twisting of the feeder member 2 can be reduced. A second embodiment of the present invention will be described wherein the pigment supply container 1 has a feeder member 2 provided with this blade portion. Figure 12 is a perspective view of the feeder member 2 for the pigment feeder container, according to the second embodiment. In this figure, designated by 21 is a blade portion of the feeder member 2 mounted so that the phase thereof is changed continuously in the direction of the axis of the axis portion 2A. The feeder member 2 provided with this blade portion 21 is preferably integrally formed by injection molding or the like, but can be divided into two or more parts that are unified by welding or joining or the like. As material of the shaft portion 2A when the feeder member 2 is divided into two parts, there is the material of plastic resin, metal or the like having a stiffness. The blade portion 21 is preferably made of laminated material with flexibility. More specifically, a single layer material or multi-layer material of polyester, polypropylene, Nylon, polyethylene or fluorine resin material. The thickness of the blade portion 21 is preferably approximately 50 μ-1 mm. In this embodiment, a polyester sheet having a thickness of 188-250 μ is used satisfactorily. The configuration of the blade portion 21 is not necessarily a specific shape such as the trapezoid shape, rather it is necessary that the length of the center of rotation of the shaft portion 2A to the free end of the blade portion 21 be substantially constant throughout the entire length of the blade portion 21 (as with the rectangular configuration, for example). From the point of view of the assembly property of the anchoring member 2, the blade portion 21 is an integral member over its entire length. Therefore, an integral blade portion 21 is preferable, and as such, the material can be used efficiently since the blade portion 21 can be cut in one piece. When the pigment forms a cake in the main body 1A of the container as a result of the main unit 100 that remains unused for a long time, the pigment can be continuously removed and the efficient discharge of the pigment is achieved when the knife portion 21 is intact ? The description of the mounting method of the blade portion 21 will be made in the axis portion 2A. When the feeder member 2 is constituted by the shaft portion 2A and the knife portion 21, it is required that the knife portion 21 be installed in the shaft portion 2 with torsion relative to the shaft portion of the shaft portion 2A so that the phase continuously changes in relation to the axial direction of the axis portion 2A. For the assembly method, as shown in , the drum portion of the shaft portion 2A is provided with corrugated projections 22 in various portions to allow assembly of the blade 2B. On the other hand, the blade portion 21 is provided with the corrugated hole portion 23 to receive the projections with corrugations 22 of the portion of the axis 2. The corrugated projections 22 are coupled in the portions of the hole with corrugations 23, and these are coupled and unified by thermal undulation or ultrasonic corrugation. On the other hand, when the mounting surface of the blade of the shaft portion 2A is twisted in the direction with the axis direction, as shown in figure 13, the mounting surface 2d (shaded portion) of the blade portion 21 of the shaft portion 2 changes continuously with respect to to the direction of the axis of the axis portion 2A.
Then, the blade portion 21 is assembled and unified with the axis portion F by adhesive material or a double layer tape or the like on the surface 2d. In either type, it is preferred that the phase difference of the blade portion 21 in relation to the direction of the axis is approximately 90 °. With reference to Figure 14, the operation of discharging the pigment from the feeder member 2 having the structures already described will be described. By rotating, from 0 to 360 °, the portion of the axis 2A of the feeder member 2 in the direction of the arrow A in (1) of this figure, the entire feeder member 2 rotates sequentially in the order of (1) - > (2) - > (3) - > (4) - > (1) . During the rotation of (1) - > (2), the blade portion 21 flexes and curves as it enters the space formed between the inner bottom surface of the main body IA of the container and the portion of the shaft 2A. The blade portion 21 rotates through (2) - > (3) - > (4) while rubbing the inner bottom surface of the main body IA of the container. At this time, since the phase of the blade portion 21 continuously changes in the direction of the axis of the shaft portion 2A, the degrees of flexure of the blade portion 21 are different between the axial ends of the blade portion. Therefore, the function occurs pigment feeder in the direction of the axis of the axis portion 2A, so that the pigment is fed in the longitudinal direction (lateral direction of the main unit) of the main body IA of the container. Since the blade portion 21 makes contact with the inner bottom surface of the main body IA of the container, the pigment can be effectively fed even when the amount of pigment in the main body 1A of the container decreases, and as a result, the amount of The remaining pigment can be reduced after the end of the pigment discharge from it. In addition, the pigment is fed to the discharge outlet by the elastic return action of the blade portion 21 at the time of (4) to. (1) in Figure 14. In this manner, in addition to the feeding effect of pigment by the flexibility of the blade portion 21 at the time of contact thereof with the inner bottom surface of the main body IA of the container, the elastic return effect of the blade portion 21 further feeds the pigment and, therefore, the pigment is can feed 20 efficiently. As shown in Figs. 14, (5), by providing sufficient length from the axis portion 2A to the free end of the blade portion 21, the TI pigment which formed a cake can be separated by the elasticity of the blade portion 21. Thus, this embodiment is useful with a container of the type wherein the height of the main body 1A is so large that the portion of the pigment-supplying port takes it one position below the main body of the container, so that the latitude is improved by reducing the limit for the configuration, whereby the space is the main unit of the image forming apparatus can be used effectively. The pigment discharge experiments have been carried out using the supply container of pigment 1 of the structure already described, and it has been confirmed that the stable pigment discharge property was achieved (amount of pigment discharge per unit time), and the amount of pigment remaining in the container after the discharge was as small as approximately 10 g. The initial torque required for the rotation of the feeder member 2 was approximately 2 kgf-cm. In the experiments, the blade portion of the feeder member 2 was of a polyester sheet having a thickness of about 188 μ and was mounted to the portion axis 2A of ABS resin material using a double coated tape. The main body IA of the container contained approximately 1500 g of pigment, and the feeder member 2 was rotated at the speed of the rotation sequence of approximately 30 rotations per minute for the pigment discharge.
The rotation speed of the feeder member 2 was changed in the range of 20-50 rotations per minute, and the change of the discharge property was verified, and the amount of pigment discharge per unit time 5 was found to increase with the increase of the rotation speed. Therefore, it was found that the amount of pigment discharge per unit time can be controlled by controlling the rotation speed of the feeder member 2. As a case of pigment forming cake in the main body IA of the container, the main body 1A of the container was tapped after the pigment was filled, and after this the discharge experiments were carried out. More specifically, the container filled with the pigment was fixed on a tapping platform with the same position of the container as in the pigment discharge, and the knocking platform was dropped a thousand times with the height of 100 mm and the frequency of 2 Hz. As a result, the discharge property of the pigment and the rest of the amount of pigment were substantially the same as with the experiments without tapping, so that it was confirmed that the pigment can be effectively discharged while the pigment is in cake or not. The initial torque required for the rotation of the feeder member 2 is slightly greater r (approximately 5 Kgf-cm), but is not so high that the driving force is overloaded. The torque for rotation is maximum when the knife portion 21 enters the pigment that formed cake (1) and (2) in Figure 14). When the feeder member 2 has such a structure that it changes the phase of the knife portion 21 in the axial direction, the synchronization of the knife portion 21 entering the pigment is # different in the direction of the axis, so that the moment torsion of the rotation can be reduced. In this embodiment, the phase of the blade portion 21 changes in the axial direction, and therefore, even if a portion of the blade portion 21 is in the condition shown in Figure 14 (3) the state of (1) ) in figure 14 exists in another position, so that the blade portion 21 is prevented from becoming entangled around the shaft portion 2A. In this way, according to the present invention, the blade portion is prevented from becoming entangled around the axis portion. Figure 16 shows a feeder member 2 according to the second embodiment wherein a screw member 2e is added to the structure of figure 12 adjacent to the portion of the pigment supplying port of the sealing member 2. In another sense, the structures this The modality is the same as the first embodiment, and the pigment discharge experiments were carried out under the same conditions using the pigment supply container 1 of the first embodiment. As a result, the pigment discharge property was better than in the first mode, and the amount of pigment remaining after the end of the pigment discharge was about 10g. As a result of the addition of screw member 2e, the amount variation of # Pigment discharge was 5-10 g / min, which was better than 10-20 g / min. In the first embodiment and the improved stability of the amount of pigment discharge was confirmed. The initial torque required for the rotation of the feeder member 2 was approximately 4 Kgf-cm The rotation speed of the feeder member 2 was changed in the range of 20-50 rotations per minute, and the property change was verified, and it was found that the amount of pigment discharge per unit time increased with the increase of the rotation speed. Therefore, it was found that it is possible to control the amount of discharge of pigment per unit time controlling the rotation speed of the feeder member 2. The amount of pigment discharge per unit time was stable from the initial stage to the final stage of the pigment discharge when the pigment formed Cake before the pigment was discharged by bypass of the container and when 1 cake of the pigment was undone by shaking the supplying container 1 by the user before it was mounted to the main unit 100 of the apparatus. For example, when the feeder member 2 is rotated at 36 rpm, the amount of pigment discharge was 70-100 / min. Regardless of the previous state of the pigment. When the pigment does not form cake and is loose, the pigment that has high fluidity tends to precipitate or # accelerate towards the exit of the discharge (the port supplier of pigment Ig) and discharges at an unnecessarily high speed (flows violently), but this phenomenon does not occur with the embodiment of figure 16. This is because at least one full turn of the screw member 2e that has the helical configuration is arranged in the supplying portion of cylindrical pigment so that the pigment that runs easily can be adequately stopped by this means. The discharge experiments were carried out for the pigment supply container 1 filled with the pigment after it was hit a thousand times. As a result, the pigment discharge property and the amount of pigment remaining in the container were similar to the case without tapping. The initial torque required for rotation of the feeder member 2 is slightly higher (approximately 8 kgf / cm) but it is not so high that the power source is overloaded. Figure 17 shows a structure wherein a portion of the blade portion 21 of the feeder member 2 shown in Figure 13 is removed to provide a window configuration 21a, according to a third embodiment of the present invention. With the arrangement of the window configuration 21a, the pigment discharge experiments were carried out under the same conditions for the pigment supply container 1 having the same structure as with the first mode except for the window. As a result, the property of pigment discharge, the amount of pigment remaining in the body The main IAA of the container after finishing the loading, were the same as with the first mode. The initial torque required for the rotation of the feeder member 2, when the knocking was not carried out, was approximately 2 kgf-cm which is the same as in the first modality. The initial torque required after the 1000 taps was decreased from about 5 kgf-cm, which is the torque without the window, to about 4 kgf-cm; the initial twisting moment when the pigment became agglomerated decreased through the window.
Figure 18 shows a structure of a feeder member 2 according to a fourth embodiment wherein a screw member 2e shown in figure 16 is added to the feeder member 2 shown in figure 17. The 5 experiments of the pigment discharge they were carried out under the same conditions as with the first embodiment, except for the arrangement of the screw member 2e and the configuration of '/ entana 21a. As a result, the download property of pigment, was better than with the third mode in the stability, and the amount of pigment remaining in the container after the end of the discharge, were equivalent to those of the third mode. The initial torque required without tapping was approximately 4 kgf-cm similar to the second modality. The initial torque required after 1000 taps decreased from about 8 kgf-cm without the window to approximately 6 kgf-cm. In this way, through the provision of blade portion 21 in the shaft portion 2A of the feeder member 2 in which the blade phase continuously changes in relation to the axial direction of the shaft portion 2A, the pigment feed function becomes more effective, and the amount of pigment that remains in the main unit of the container can be reduced. Further, ? by arranging the windows in one or more portions of the blade portion 21, the required torque portion of the rotation can be reduced. In this invention, the cover 15 for the exchange and the hinge portion 18 for this can be provided in the positions shown in Figure 19. With reference to Figures 19 and 20, the structure for opening and closing the supplying port of tones lg * by the movement of the exchange cover provided in the position will be described below. Figure 19 shows the state where the cover 15 is open, and Figure 20 shows the state where the cover 15 is closed. In these figures, the same preference numbers as in Figure 8 are assigned to the elements having the corresponding functions, and detailed descriptions of these will be omitted for simplicity. In FIGS. 19, 20, designated 19, there is a member supporting the pigment-supplying container having a center of rotation which is concentric with the pigment-receiving port 9, and the pigment-supplying container 1 is mounted on the support member of pigment supply vessel 19 with the exchange operation.

The sealing member 303 hermetically seals the pigment supply port 301g by press fit the clutch portion 303bl of the sealing portion 303b in the portion of the pigment supply port 301a from the pigment supplying port 301g. Designated by 303c is a clutch portion the which functions as a receiving portion of the driving force (impeller) for receiving the driving force to rotate the feeder member 302 from the main unit 100 of the apparatus when the pigment supply container 301 is mounted to the main unit 100. The clutch portion 303c is provided with a projected portion 303cl extended from the sealing portion 303b substantially coaxial with the axis of the axis portion 302A of the feeder member 302 in the opposite direction from the main body 301A of the pigment container (when the sealing member 303 mounts to the main body 301A of the container). The clutch portion 303c is provided on the curved surface of the projected portion 303cl, and is provided with elongated projections (rib) 303d (groove-like), which function as a portion receiving the engaging drive force with the coupling member. 304. In this mode, two of these 3d groove projections are provided at the same distance. More specifically, these are willing to ^^ intervals of approximately 180 °. The rib 303d projects from the external surface of the sealing member by 0.5 mm -3 mm, preferably approximately 1.8 mm. The external diameter of the projected portion 303C1 is 10 mm - 14 mm, preferably approximately 12 mm. The sealing member 303 includes a clutch hole 303a as a drive portion transmitting the driving force received from the main unit 100 to the feeder member 302 by engagement with an end portion 302a of the feeder member 302. The clutch hole 303a is formed as a hole (hole) through the sealing portion 303b and the clutch portion 303c. At this point, the clutch hole 303a has a rectangular portion corresponding to the rectangular configuration of the end 302a of the axis of the feeder member 302 projected from the powder pigment supplying portion 301a. This has a dimension slightly larger than the end 302a of the shaft, so that the end 302a loosely fits into the clutch hole 302a. The feeder member 302 and the sealing member 303 are locked to each other in the direction of rotation by loose fitting between the end 302a and the clutch hole 303a. On the other hand, in the axial direction the relative movement between these. In doing so, the sealing member 303 and the main body 301A of the container are separable from each other so that the pigment supplying port 301g can be opened with the assembly of the pigment-supplying container. The length of the clutch between the clutch hole 303a and the end of the shaft 302a is quite long to prevent disengagement between them when the sealing member 303 and the main body 301A of the container move away from each other. Therefore, even if the sealing member 303 moves away from the main body 3OYA, the feeder member 302 can receive the driving force through the sealing member 303 (clutch portion 303c). Between the clutch portion 303c and the sealing portion 303b, a flange portion 3f is provided which abuts the end of the powder pigment supplying portion 303a when the sealing portion 303b pressures into the portion of the pigment supplying port 301a. The outer diameter of the flange portion is substantially equal to the outer diameter 5 of the portion of the pigment supply port 301a (preferably smaller than the outer diameter of the portion of the pigment supply port 301a).

The sealing member 303 is required to have an adequate elasticity to effect the adjustment by pressure in the pigment supply portion 301a to seal it. The material is polypropylene, Nylon, high density polyethylene or similar, but the most preferable material is low density polyethylene. Designated by 303j is a locking slot for receiving a blocking member 6 provided in the main unit 100 of the apparatus. The amplitude of the locking slot 303j is 1.5 mm - 5 mm, preferably about 3 mm. The depth of the locking groove is 0.5 mm-5 mm, preferably about 2.5 mm. As described in the foregoing, the sealing member 303 has a substantially cylindrical clutch portion 303bl engageable with the pigment supply port portion 303a. The flange portion 303f is substantially coaxial with the clutch portion 303bl. It also includes a projected portion 303cl projecting from the flange portion 303f substantially coaxial with the clutch portion 303bl on an opposite side from the side where the clutch portion 303bl is provided. Adjacent to the free end portion of the projected portion 303cl is provided with a locking groove 303c and a free end portion is formed in the locking portion 303e. There is provided a hollow portion extending from the side of the clutch portion 303bl to the side of the locking portion 303e, and in the "hollow portion there is provided a transmitting portion of the driving force 303a. of the hollow portion does not open, and therefore, when the tuck portion 303bl engages the portion of the pigment supply port 303a, the pigment does not leak from the hollow portion outwards. of the pigment supply port 303a is sealed by mounting the sealing member 303. In the same manner for the modes 1 and 2, the sealing member 303 has 4 functions.Most specifically, the functions are: (1) to seal the port portion pigment provider 301a, (2) receive the transmission of rotational force from the main unit 100 of the apparatus, (3) transmit the rotational force towards the feeder member 303 and (4) engage with the clutch member 6 provided in the main unit of the device. From In this manner, the sealing member 303 transmits the driving force received from the main unit 100 of the apparatus to the shaft portion 302A by the extension portion 302C to rotate the feeder member 302. The description will be made for the agitator member. 305. Referring to Figure 28, (A) is a front view of agitator member 305, (B) is a left side view, and (C) is a right side view. As shown in Figure 28, the agitator member 305 includes a shaft portion 305a, a rigid blade portion 305b and a portion of flexible blade 305c.

The clutch portion of the blade portion 305b, which are engagable with the shaft portion 305a has a configuration that conforms to the shaft portion 305a for receiving the driving force from the shaft portion 305a, and this rotates with the rotational movement of the shaft portion 305a to agitate the pigment in the vessel. It is preferable to provide a removable portion 305h at one end as shown in figure 28 since then the assembly is simple. The full length of rigid blade portion 305b is in the form of a plate substantially parallel in relation to the direction of tangential rotation, and the downstream side of the portion The blade with respect to the direction of rotation bends towards the surface of the inner wall of the pigment-supplying vessel. The length r of the bent portion 305bl shown in Fig. 29 is approximately 2 mm-8 mm, and the flexure angle 6 is preferably about 30 ° - 50 °. More preferably, the length r of the bent portion 305b is about 3mm-5mm, and the flexure angle is preferably about 45 °. In this mode, the length of the portion flexed '305bl is approximately 5 mm, and the flexion angle is approximately 45 °. The distance from the center of the axis of rotation towards the free end of the rigid blade portion is suitably determined depending on the size of the main body of the container, and is preferably about 70-95% of the internal radius of the main body of the container. In this modality, the internal diameter of the main body of the container is approximately 44.5 mm, and therefore, it is approximately 39.4 The flexible blade portion 305c is of material with little rigidity, such as a film or sheet of plastic resin material or elastomeric sheet. The thickness of this is preferably about 50 μ ~ 500 μ and more preferably 100 μ 300 μ. In this modality we used a sheet of polyester having a thickness of about 100 microns. The flexible blade portion 305c is joined such that the free end makes contact with the surface of the inner wall of the main body over the entire length of the flexed portion 305bl of the rigid blade portion 305b. This rotates by scraping the pigment from the inner wall surface of the container with the rigid blade portion. The length, in the radial direction, of the flexible blade portion 305c is preferably longer in approximately 0.5 mm-10 mm than the distance between the surface of the inner wall of the container and the free end of the rigid blade portion 305b since then the effect described above can be improved. In this mode, it is longer by approximately 6 mm. The joint between the rigid blade portion 305b and the flexible blade portion 305c is made by a double layer tape 305i (DIC # 8800CH), as shown in Figure 30, in the bent portion 305b of the rigid blade portion 305b. Another method uses rivets or another is usable Known means or the integrated molding with the rigid blade portion is usable. As shown in Figure 31, the rigid blade portion 305b can be divided with a 180 ° phase difference substantially in the central portion with relation to the direction of the axis, so that the divided parts are staggered. The number of divisions is suitably determined depending on the configuration and length of the main body of the container, and may be 3 or 4 or more. The phase of the rigid blade portion 305b can change over its entire length to provide a spiral-like configuration. The clutch portion between the central portion of the shaft portion and the opposite ends of the rigid blade portion 305b is preferably provided with a releasable portion 305h as shown in the figure since the assembly property is then improved. The length of the bent portion of the rigid blade is approximately 3 mm to reduce the strength of the pigment and decrease the projected area of the rigid blade portion in the direction of rotation. The length and the flexion angle of the bent portion is preferably 2-8 mm and 30-50 °, and more preferably approximately 3-5 mm and approximately 45 °. The rigid blade portion 305b and the flexible blade portion 305c may be corrugated by means of aluminum rivets 4i. In this case, if the position of the rivet hole of the flexible blade portion 305c deviates even slightly, ripple may result and, therefore, it is preferable to provide the perforation or a half cut in a portion of the flexible blade portion 305c which makes contact with the bent portion C of the rigid blade portion 305b. The joining means may be a double-coated tape or other known means. The description will be made of the method of assembling the pigment-supplying container 301.
