Description

  The present invention relates to a toner cartridge of a printer.

  In order to prevent toner leakage during transportation, a toner seal for sealing the toner supply port is attached or welded to the toner cartridge. When inserting the toner cartridge into the printer, it is necessary to remove the toner seal. If you forget to remove the toner seal, it may be caused by a printing failure in a printing device such as a printer or copier, or a paper jam that occurs inside the printing device. A failure such as a jam occurs. When a jam occurs, the printing medium such as paper cannot be sent and cannot be printed, so that it becomes necessary to open the cover of the housing and remove the jammed printing medium.

  Various methods for preventing this have been proposed. For example, when the toner seal is forgotten to be removed and inserted into the printer, there is a method in which a malfunction is displayed on the operation panel without operating the printer. In this case, the user sees an operation failure by looking at the operation panel, pulls out the cartridge, peels off the toner seal, and reinserts the toner cartridge.

  Also, a printer that automatically performs test printing when the toner cartridge is replaced and displays an instruction to remove the toner seal on the display unit when blank paper is printed due to forgetting to remove the toner seal is also proposed. (Patent Document 1).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of an essential part for explaining the internal configuration of a full-color image forming apparatus (hereinafter simply referred to as a printer).

  A printer 1 shown in FIG. 1 is an electrophotographic and secondary transfer tandem type color image forming apparatus, and mainly includes an image forming unit 2, an intermediate transfer belt unit 3, a paper feeding unit 4, and double-sided printing. It is composed of a transport unit 5.

  The image forming unit 2 has a configuration in which four image forming units 6 (6M, 6C, 6Y, and 6K) are arranged in a multistage manner from right to left in FIG.

Three image forming units 6 on the upstream side (right side in the figure) of the four image forming units 6
M, 6C, and 6Y are magenta (M), cyan (C), and three subtractive primary colors, respectively.
A mono-color image is formed using yellow (Y) color toner, and the image forming unit 6K forms a monochrome image using black (K) toner mainly used for dark portions of characters and images.

Each of the image forming units 6 has the same configuration except for the color of the toner stored in the toner container (toner cartridge). Accordingly, the configuration of the black (K) image forming unit 6K will be described below as an example.

  The image forming unit 6 includes a photosensitive drum 7 at the bottom. The peripheral surface of the photosensitive drum 7 is made of, for example, an organic photoconductive material. A cleaner 8, a charging roller 9, an optical writing head 11, and a developing roller 13 of the developing device 12 are arranged around the periphery of the photosensitive drum 7.

  The developing device 12 puts one of magenta (M), cyan (C), yellow (Y), and black (K) toners in the upper toner container as indicated by M, C, Y, and K in the drawing. An intermediate portion is provided with a toner replenishing mechanism for the lower portion.

  Further, the developing roller 13 is provided at the lower side of the developing device 12 in the side opening, and a toner stirring member, a toner supply roller 19 for supplying toner to the developing roller 13, and a toner layer on the developing roller 13 are fixed A doctor blade that regulates the layer thickness is provided.

  The intermediate transfer belt unit 3 has an endless transfer belt 14 extending in a flat loop shape from substantially the left and right sides of the figure at the approximate center of the main unit, and the transfer belt 14 is stretched over the transfer belt 14. A driving roller 15 and a driven roller 16 are provided to circulate and move the belt 14 counterclockwise in the drawing.

  The transfer belt 14 transfers the toner image directly to the belt surface (primary transfer), and further transfers the toner image to a printing medium such as paper (secondary transfer) to the transfer position to the printing medium. Here, the entire unit is referred to as an intermediate transfer belt unit.

  The intermediate transfer belt unit 3 includes a belt position control mechanism 17 in the loop of the flat loop-shaped transfer belt 14. The belt position control mechanism 17 includes a primary transfer roller 18 including a conductive foam sponge that presses against the lower peripheral surface of the photosensitive drum 7 via the transfer belt 14.

The belt position control mechanism 17 has three primary transfer rollers 18 corresponding to the three image forming units 6M, 6C, and 6Y of magenta (M), cyan (C), and yellow (Y) as vertical support shafts. Rotate to the center with the same period.

Then, the belt position control mechanism 17 rotates and moves one primary transfer roller 18 corresponding to the black (K) image forming unit 6K at a rotational movement cycle different from the cycle of the three primary transfer rollers 18. The belt 14 is moved away from the photosensitive drum 7.

That is, the belt position control mechanism 17 sets the position of the transfer belt 14 of the intermediate transfer belt unit 3 in the full color mode (all four primary transfer rollers 18 are in contact with the transfer belt 14),
The mode is switched to the monochrome mode (only the primary transfer roller 18 corresponding to the image forming unit 6K is in contact with the transfer belt 14) and the all non-transfer mode (all the four primary transfer rollers 18 are separated from the transfer belt 14).

In the intermediate transfer belt unit 3, a belt cleaner unit is disposed further upstream of the uppermost image forming unit 6M on the upstream side in the belt movement direction, and is flat and thin so as to be substantially along the entire lower surface. The waste toner collecting container 20 is detachably disposed.

The paper feed unit 4 includes two paper feed cassettes 21 arranged in two upper and lower stages, and each of the two paper feed cassettes 21 has a printing medium take-out roller in the vicinity of the paper feed opening (right side in the drawing). 22, a feeding roller 23, a separating roller 24, and a standby conveying roller pair 25 are disposed.

  A secondary transfer roller 26 that is in pressure contact with the driven roller 16 via the transfer belt 14 is disposed in the print medium conveyance direction (vertical upward direction in the figure) of the standby conveyance roller pair 25, so The next transfer portion is formed.

A belt-type heat fixing device 27 is disposed on the downstream side (upward in the drawing) of the secondary transfer unit, and on the further downstream side of the belt-type heat fixing device 27, the printing medium after fixing is belt-type heat fixing. An unloading roller pair 28 that unloads from the apparatus 27 and a discharge roller pair 31 that discharges the unloaded printing medium onto a discharge tray 29 formed on the upper surface of the apparatus are disposed.

The duplex printing conveyance unit 5 includes a start return path 32a that branches from the intermediate conveyance path between the carry-out roller pair 28 and the discharge roller pair 31 to the right lateral direction in the drawing, and then an intermediate return path 32b that bends downward. An end return path 32c that bends in the left lateral direction opposite to the above and finally reverses the print medium to be returned, and four return roller pairs 33a, 33b, 33c, and 33d arranged in the middle of these return paths. It has.

The exit of the end return path 32 c communicates with a conveyance path to the pair of standby conveyance rollers 25 corresponding to the sheet feeding cassette 21 below the sheet feeding unit 4. In this example, a cleaning unit 35 is disposed on the upper surface of the intermediate transfer belt unit 3.

The cleaning unit 35 comes into contact with the upper surface of the transfer belt 14 to scrape and remove the waste toner, and stores the toner in a temporary storage unit of a belt cleaner unit (not shown). The inside is conveyed to the upper part, and sent to the waste toner collecting container 20 through a dropping cylinder.

FIG. 2 is a perspective view showing the appearance of only one image forming unit 6 taken out. As shown in FIG. 2, the image forming unit 6 includes a developing device 12 held by an exterior frame 36,
The drum unit 37 is integrated with the developing device 12 and is held by an exterior frame 36. In FIG. 2 and FIG. 3 shown next, it is shown in the same vertical direction that is actually mounted inside the printer 1.

The drum unit 37 is formed with an elongated groove-like long hole 38, and the upper surface of the photosensitive drum 7 is positioned below the long hole 38. The image forming unit 6 is mounted on the printer with the light emitting portion at the tip of the optical writing head 11 positioned in the long hole 38.

  FIG. 3 is a diagram showing that the toner cartridge 60 is configured to be inserted into and removed from the developing unit 42 of the developing device 12 in the image forming unit 6 shown in FIG. As shown in FIG. 3, the toner cartridge 60 can be inserted into and removed from the developing unit 42 of the developing device 12 integrated with the drum unit 37 in the direction p in FIG. 3, that is, the direction orthogonal to the printing medium conveyance direction. Composed.

  A lock knob 64 is provided at the front end of the toner cartridge 60 to prohibit the operation of pulling out the toner cartridge 60 after the toner cartridge 60 is mounted. Although not shown in the drawing, a toner supply port is provided at the bottom 60 b of the toner cartridge 60.

  FIG. 4 is a diagram illustrating a basic operation state in which the user replaces the toner cartridge 60 in the printer 1. FIG. 4A is a diagram illustrating an operation of opening the front door 50 of the printer 1 and taking out one of the four empty (used) toner cartridges 60. Hereinafter, the front door 50 side of the printer 1 is referred to as a front side, and the opposite side is referred to as a back side.

  When taking out the used toner cartridge 60, the lock knob 64 is turned in the release direction to release the lock. Then, the toner cartridge 60 stored in the cartridge storage chamber 55 is pulled out in the q direction, which is the front direction, and the toner cartridge 60 is taken out. The cartridge storage chamber 55 is configured by the exterior frame 36 and the like.

  FIG. 4B is a diagram illustrating an operation of attaching a new toner cartridge 60 after the used toner cartridge 60 is taken out. After the user removes the toner seal, the user inserts a new toner cartridge 60 into the opening 55a of the cartridge storage chamber 55 along the arrow p direction (toward the back side).

  The user inserts the toner cartridge 60 all the way, and then turns the lock knob 64 in the locking direction to complete the mounting.

5 and 6 show the configuration of the toner cartridge 60 in the present embodiment.
FIG. 5 is an enlarged view of the toner cartridge 60 as seen from the bottom direction, and is a perspective view showing the toner seal 70 and the peeling member 72 in an exploded state from the toner cartridge 60.

  FIG. 6 is an enlarged view of the toner cartridge 60 viewed from the bottom direction, and is a perspective view showing a state in which the toner seal and the peeling member are attached. 5 and 6, the toner cartridge 60 has the same longitudinal direction as that in FIG. 4, but in order to show the configuration of the toner seal 70 and the like, the toner cartridge 60 is turned upside down. The bottom of is shown facing up. The insertion direction p of the toner cartridge 60 is as illustrated.

  As shown in FIG. 5, a toner supply port 62 is provided at the bottom 60 b of the toner cartridge 60. The toner supply port 62 is provided at the bottom 60b as an elongated opening along the longitudinal direction at a substantially central portion of the toner cartridge 60 in the longitudinal direction.

  The toner supply port 62 has a long hole shape and is an opening for supplying the toner stored in the toner cartridge 60 to the developing unit 42. The toner falls from the toner supply port 62 and is supplied to the developing unit 42 disposed immediately below the toner cartridge 60.

  In order to prevent the toner from leaking from the toner supply port 62 during transportation or the like, the toner supply port 62 is sealed by a toner seal 70 and attached so as to shield the toner supply port 62.

  The toner seal 70 is affixed to the position of the bottom 60b of the toner cartridge 60 so as to shield the toner supply port 62 indicated by a broken line in FIG. The toner seal 70 is an elongated belt-like sheet provided with an adhesive layer on the back surface, and an arrow 70a indicating the peeling direction is printed on the front surface. The toner seal 70 is, for example, a PET film.

  A peeling member 72 is provided at the front end of the toner seal 70. The peeling member 72 is attached to the back side of the toner seal 70 and is provided so as to be sandwiched between the toner seal 70 and the bottom 60b. The adhesive force between the toner seal 70 and the peeling member 72 is set to be larger than the adhesive force between the toner seal 70 and the bottom portion 60b.

  The peeling member 72 has a width larger than the short direction of the toner seal 70 and a length shorter than the longitudinal direction of the toner seal 70, and a part of the toner seal 70 is attached to the toner seal 70 from the toner supply port 62. It is for peeling.

  The peeling member 72 has a rectangular base portion 72a and a section portion 72c provided so as to extend in the vertical direction from both ends of one side on the front side in the longitudinal direction of the base portion 72a. A long hole 72b is provided in the center of the base 72a in a direction parallel to the longitudinal direction.

  The peeling member 72 is affixed to the toner seal 70 in such a direction that the longitudinal direction of the base 72a is orthogonal to the insertion direction. When the longitudinal direction of the base portion 72 a is defined as the width, the width w is configured to be larger than the width y of the semicircular bottom portion 60 b of the toner cartridge 60.

  By doing so, it can be used for positioning in a direction orthogonal to the insertion direction p of the toner cartridge 60 when the toner seal 70 is attached to the peeling member 72 in the manufacturing process. That is, the toner seal 70 can be accurately attached to the center of the base 72 a of the peeling member 72 while observing the balance of the left and right elongated holes 72 b in the base 72 a of the peeling member 72 below the toner seal 70.

  Further, by making the left and right side lengths of the outer peripheral edge of the elongated hole 72b of the base 72a of the peeling member 72 large enough not to contact the toner cartridge 60, the toner seal 70 is peeled off. It can also be used as a “knob”.

  Further, since both ends of the base portion 72a protrude beyond the width of the toner cartridge 60, the back surface of the base portion 72a becomes an abutting portion 72d that abuts against the opening 55a of the cartridge storage chamber 55, as will be described in detail later.

  The two sections 72 c are members for stably holding the peeling member 72 on the semicircular bottom 60 b when viewed from the back side of the toner cartridge 60. The slopes inside each of the two sections 72c are in contact with the semicircular bottom 60b of the toner cartridge 60 to stabilize the position of the peeling member 72.

  The peeling member 72 is manufactured by, for example, removing and bending a resin sheet material.

  FIG. 6 is a view showing the toner cartridge 60 to which the peeling member 72 and the toner seal 70 are attached in a state of the toner cartridge 60 before the toner seal 70 is peeled off. The peeling member 72 is attached at a position close to the back side of the toner cartridge 60 in such a posture that the base 72a is substantially horizontal.

  FIG. 7 is a schematic diagram illustrating an example of the size relationship between the opening 55 a of the cartridge storage chamber 55 and the toner cartridge 60. In FIG. 7, the vertical direction is shown in the same direction as that in FIG. That is, it is shown upside down from FIGS.

  FIG. 7A is a side view of the toner cartridge 60 before being inserted into the cartridge storage chamber 55. FIG. 7B shows the outer shape of the peeling member 72 from the opening 55 a of the cartridge storage chamber 55 and the toner cartridge 60 as viewed from the back side. The projected shape of the toner cartridge 60 viewed from the back side is indicated by a solid line, and the opening 55a is indicated by a one-dot chain line.

  The opening 55 a of the cartridge storage chamber 55 is formed in a shape along the projected shape from the back side of the toner cartridge 60. By doing so, the user can intuitively understand the insertion direction of the toner cartridge 60 without a manual or the like, and can reliably prevent erroneous mounting. Further, by eliminating unnecessary gaps between the toner cartridge 60 and the mounting portion, it is possible to prevent dust and the like from entering the interior after mounting.

  In the drawing, the shape of the opening 55a is shown along the shape of the entire back surface of the toner cartridge 60. However, the shape does not necessarily need to be faithful to the shape of the back surface of the toner cartridge 60. . The shape of the opening 55a may be any shape that can reliably guide the insertion of the toner cartridge 60.

  When the toner cartridge 60 in which the toner seal 70 is forgotten to be removed is inserted, the abutting portion 72d of the base portion 72a of the peeling member 72 abuts against (collises with) the opening 55a. Specifically, the abutting portion 72d abuts against the front surface 55b of the cartridge storage chamber 55 that forms the opening 55a. The front surface 55b is a part of the exterior frame 36, for example.

  That is, when the toner cartridge 60 without the toner seal 70 being peeled is inserted, the peeling member 72 hits the opening 55a of the cartridge storage chamber 55, and the touched feeling is transmitted to the user's hand. As a result, the user notices that he / she has forgotten to remove the toner cartridge 60, removes the toner cartridge 60, grasps the peeling member 72, peels off the toner seal 70, and then reinserts it, thereby realizing normal loading.

  8, 9, and 10 are diagrams for explaining how the toner seal 70 is peeled from the toner cartridge 60 when the toner cartridge 60 for which the toner seal 70 has been forgotten to be removed is inserted into the cartridge storage chamber 55. is there.

  As described above, when the toner cartridge 60 with the toner seal 70 forgotten to be removed is inserted, the peeling member 72 hits the opening 55a of the cartridge storage chamber 55 immediately after the insertion starts, so that the user forgets to remove it. The chances of noticing it should be high.

  However, in some cases, there is a possibility that the insertion of the toner cartridge 60 may be continued without noticing the contact of the peeling member 72. It will be described below that the toner seal 70 is further peeled off by the peeling member 72 even when the insertion of the toner cartridge 60 is continued without noticing the abutting by the peeling member 72.

  Note that FIG. 8 shows only the toner cartridge 60 while omitting the illustration of the cartridge storage chamber 55 in order to clearly show the peeling mode of the peeling member 72 from the toner seal 70. Also, the vertical orientation of the toner cartridge 60 is reversed from the vertical orientation when inserted, as in FIGS.

  As an aspect in which the toner seal 70 is peeled, the following two patterns will be described as representatives. The first pattern is a pattern that is peeled in the order of (A) → (B) → (C) as the toner cartridge 60 is inserted. The second pattern is a pattern in which peeling is performed in the order of (A) → (B) → (D) → (E) as the toner cartridge 60 is inserted.

  The first pattern will be described. FIG. 8A shows a state before the toner cartridge 60 is inserted into the cartridge storage chamber 55, which is the same state as FIG. When the toner cartridge 60 is inserted into the cartridge storage chamber 55, the abutting portion 72 d of the base portion 72 a abuts against the opening 55 a (front surface 55 b) of the cartridge storage chamber 55.

  If the insertion of the toner cartridge 60 is continued as it is, the peeling member 72 is kept outside the opening 55a, so that the toner seal 70 integrated with the peeling member 72 starts to peel off from the back side portion. Here, as shown in FIG. 8B, the peeled portion 70b of the toner seal 70 has a protruding shape that does not enter the inside of the opening 55a but remains outside and protrudes.

  FIG. 9 is a side view of the toner cartridge 60 shown in FIG. 8B, and is an enlarged schematic view showing the peeling portion 70b of the toner seal 70 shown in FIG. 8B. Note that FIG. 9 is the same as FIG. As described above, the abutting portion 72d stays before entering the opening 55a, and the peeling portion 70b of the toner seal 70 protrudes upward as viewed in the figure outside the opening 55a.

  As the toner cartridge 60 is inserted, the toner seal 70 is peeled off. However, the intermediate portion of the toner seal 70 may be difficult to peel off. In this case, as shown in FIG. 8C, the toner cartridge 60 is inserted with the peeled portion 70c of the toner seal 70 remaining in the opening 55a. FIG. 10 is an enlarged schematic view showing a state where the peeling portion 70c of the toner seal 70 shown in FIG. 8C remains inside the opening 55a.

  Further, in this case, the posture of the peeling member 72 is rotated by 90 ° from the posture shown in FIG. 8B, and the posture is changed so that the base portion 72 a stands with respect to the bottom portion 60 b of the toner cartridge 60.

  In such a state, even when the toner cartridge 60 is inserted all the way into the cartridge storage chamber 55, the toner seal 70 is attached to the toner cartridge by pulling the peeling member 72 that remains outside the opening 55a. It can peel completely from 60.

  The second pattern will be described. 8B, when the toner cartridge 60 is further inserted, as shown in FIG. 8D, the protruding peeling portion 70b is folded under the base portion 72a and FIG. As in the case of (), the toner seal 70 may be peeled off with the peeled portion 70d remaining inside the opening 55a.

  FIG. 8E shows a case where the toner cartridge 60 is inserted to the back of the cartridge storage chamber 55 in such a state. The toner seal 70 is peeled off from the toner cartridge 60, but remains in the cartridge storage chamber 55. Also in this case, the toner seal 70 can be easily removed from the cartridge storage chamber 55 by pinching and pulling the peeling member 72 outside the opening 55a.

  As described above, by providing the peeling member 72 at the tip of the toner seal 70, forgetting to remove the toner seal 70 can be reliably prevented. The function of the peeling member 72 will be described again.

  First, the peeling member 72 functions as a knob member for facilitating the operation of peeling the toner seal 70 from the bottom 60b before the user inserts the toner cartridge 60.

  Since the peeling member 72 at the tip of the toner seal 70 is not bonded to the bottom portion 60b, the toner seal 70 can be easily peeled by pinching the peeling member 72 by hand and pulling it in the front direction.

  Secondly, the peeling member 72 is a member for notifying the user of forgetting to remove the toner seal 70 when the toner cartridge 60 is inserted without forgetting to remove the toner seal 70. By hitting the opening 55a of the cartridge storage chamber 55, the user is reminded of forgetting to remove it.

  Thirdly, the peeling member 72 peels off the toner seal 70 even when the toner cartridge 60 to which the toner seal 70 has not been peeled is inserted as it is. The peeled toner seal 70 can be removed from the inside of the cartridge storage chamber 55 by pulling the peeling member 72 that remains outside the opening 55a.

At least the effects achieved by the above embodiment are listed.
1) Since a toner seal can be peeled off by adding a toner cartridge by adding a peeling member having a simple shape, forgetting to remove the toner seal during loading can be easily prevented. Manufacturing costs are low.

  2) Further, since the peeling member attached to the toner seal is a member having an area larger than that of the toner seal, it is easy to pick up and is not adhered to the toner cartridge, so that the end surface of the toner seal is easily peeled off.

  3) Compared to the method of detecting forgetting to remove the toner seal and displaying a warning display on the screen, this method is easy to understand even for beginners and is user-friendly. In addition, a display for warning of forgetting to peel off becomes unnecessary.

  4) Even if the abutting part hits the opening, the toner cartridge is inserted as it is, the toner seal is peeled off, and the toner seal can be easily removed. The trouble of inserting can also be saved.

  In the above-described embodiment, the peeling member is attached to the bottom of the toner cartridge so as to be horizontally oriented. However, the present invention is not limited to this, and the attachment position and angle are appropriately set according to the storage direction of the toner cartridge. Can be set. Further, the shape of the section provided at both ends of the base is not limited to this, and the section may be omitted and only the base may be used.

  In the above-described embodiment, the abutting portion is described as being configured separately from the toner seal. However, the abutting portion and the toner seal are configured integrally with a part of the toner seal as the abutting portion. Also good.

  Although the embodiments of the present invention have been described, the present invention is included in the inventions described in the claims and their equivalents. Hereinafter, the invention described in the scope of claims at the beginning of the filing of the present patent application will be added.
