This document pertains generally, but not by way of limitation, to coupling or engagement mechanism and components for powder, toner or developer containers.
Powder cartridges, containers or devices are known to hold or contain powder used for printing or copying. The powder, such as toner or developer, is dispensed from the powder cartridge and into an image forming apparatus. When dispensing powder from the cartridge, the cartridge first is brought into engagement with the image forming apparatus. The cartridge is then opened to allow powder to be dispensed, exhausted or exit the cartridge and into a corresponding receiving area of the image forming apparatus.
In the industry, there are many different coupling features known to bring corresponding portions of the image forming apparatus into engagement with the cartridge and to open dispense openings or receiving areas. For example, the image forming apparatus has engagement protrusions that meet or couple with corresponding portions of the cartridge body which cause a shutter or opening on the cartridge to slide or rotate open. In another example, the image forming apparatus can have features that apply pressure or force against areas of the cartridge and translate such movement to shutters or opening mechanisms. In an example, such pressure or force causes powder to dispense or exit from the cartridge and into the image forming apparatus.
The present inventors have recognized, among other things, a problem exists related to systems for containing toner, developer or other marking powders (“powder”) that are dispensed from the system and into corresponding receptacles in image forming apparatuses, such as printers, copiers or multi-function machines. The present inventors have also recognized mechanisms used to couple the powder containing systems, in an example, do not effectively bring corresponding components of the system and imaging forming apparatus together. In an example, a powder containing system has a component that couples with a corresponding component in the image forming apparatus to join the system with the image forming apparatus. Joining the system and image forming apparatus, in an example, holds the system in place during use. In another example, joining the system and image forming apparatus opens the system to dispense powder into the corresponding receptacle in the image forming apparatus.
The present inventors have recognized a way for solving the problem related to effectively engaging the system containing the powder with the receptacle in the image forming apparatus. An example coupling mechanism is on a cartridge, container or similar device containing the powder. The coupling mechanism is, for example, a cartridge interface that has a dispense mechanism. The dispense mechanism has, for example, a dispense opening configured for communication with the receptacle, or powder receiving component, of the image forming apparatus. In an example, the dispense mechanism also has a coupling mechanism that has coupling extensions that couple with components of the image forming apparatus. When the coupling extensions couple with the image forming apparatus, a shuttle, for example, on the coupling mechanism can limit and control movement of the coupling mechanism during the process of the cartridge interface engaging with the image forming apparatus.
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. Like numerals having different letter suffixes may represent different instances of similar components. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
Printers and copiers use containers, cartridges, bottles or similar devices (hereinafter “cartridge”) to hold, contain or house toner, developer or other marking powder. These cartridges are known to be in a bottle or cylindrical configuration or a box or substantially rectangular cartridge. In one example, a bottle, or generally cylindrical, shaped cartridge is used to contain powdered substances, such as toner or developer or the like (hereinafter “powder”). Such bottle-like cartridges have, in some examples, a cartridge interface coupled with a proximal, open end of the cartridge body. In an example, the proximal end with the cartridge interface is the end of the cartridge that is first inserted into the image forming apparatus.
In an example, the cartridge is a vessel configured to hold powder. The powder is then used in an image forming apparatus to facilitate forming copies or prints on paper, fabric or other similar media. The cartridge has at least one feature configured to allow the cartridge to dispense the powder contained therein. The feature of a cartridge for dispensing powder, for example, is configured to interact with a corresponding element of the image forming apparatus that receives the powder.
Cartridge interfaces can include features that can assist with coupling the cartridge body to the interior or working parts of a copy machine or image forming apparatus (hereinafter “image forming apparatus”). Cartridge interfaces can connect or couple the cartridge body along or at any suitable portion of the cartridge to a corresponding portion of the image forming apparatus. In other examples, cartridge interfaces can connect or couple the proximal or distal end of the cartridge to a corresponding portion of the image forming apparatus.
In some examples, cartridge interfaces connect or couple the cartridge body with powder dispense areas of the cartridge. Dispense areas include openings in at least a portion of the cartridge to release or exhaust powder into powder receiving areas at corresponding areas of the image forming apparatus. In some examples, the cartridge is connected or coupled proximate to the dispense area at or near corresponding areas of powder receiving areas of the image forming apparatus.
In an example of a cartridge with a cartridge interface proximate to the dispense area, at least a portion of the cartridge interface couples the cartridge to the powder receiving area so the cartridge is held, locked, or engaged in place with the powder receiving area. The cartridge interface can be proximate to the insertion end of the cartridge or at any other location as determined by its use.
In some embodiments, the cartridge interface has multiple purposes beyond holding, locking or engaging the cartridge body and for dispensing powder from the cartridge. For example, the cartridge interface includes a mechanism to assist with opening the powder dispense port of the cartridge. The cartridge interface, for example, also engages with components of the image forming apparatus to activate or deactivate operation of the cartridge, such as electronic components, gears, lockouts or other features that are used in operation of the cartridge.
In an example cartridge 100, there is a cartridge body 102. The cartridge 100 has a distal end 104 and a proximal end 106. The proximal end 106, for example, is an insertion end, or the end a user inserts first into an image forming apparatus (hereinafter the proximal end 106 will be referred to as the insertion end 106). The hopper 1000 provides, for example, at least a portion of the support structure for the cartridge 100 when the cartridge 100 is inserted into the image forming apparatus. An example of a portion of a hopper 1000 of the image forming apparatus is illustrated in
In an example of a cartridge interface 110, as illustrated in
The cover 112, in an example, includes elements or features that communicate with the image forming apparatus. The cover 112 includes areas or features that assist in engaging, holding or coupling communication elements or electronic elements on the cover 112. In some embodiments the cartridge 100 includes a chip holder 113, and the chip holder 113 retains a chip used in communicating with corresponding features in the image forming apparatus. The chip holder 113 is, for example, a fitting formed in or with the cover 112 that includes a recess for holding or retaining a computer chip. The chip holder 113, in another example, is a protrusion, extension or addition formed or coupled with the cover 112. The chip holder 113 is located at any position corresponding with a communication portion of the image forming apparatus. For example, the chip holder 113 is located at a proximal portion 114a of the cover 112. The chip holder 113, in another example, is located on at least one longitudinally extending side 114c of the cover 112.
The cover 112, in an example, also includes identification features 115 such as lockouts, protrusions, or recesses. Such identification features 115 are known to be formed with, such as by molding, the cover 112. The identification features 115 are also known to be additions added to the cover 112 after molding or otherwise forming the cover 112. The identification features 115 include, for example, lockouts that identify regions in that the cartridge 100 is designed for use. The identification features 115 also indicate, for example, the color of powder contained within the cartridge 100. The identification features 115, in another example, also otherwise identify the type of cartridge 100 or machine that the cartridge 100 is designated.
The cover 112 also includes engagement features, such as features 117a or 117b, to properly align the cartridge 100 in the machine. Engagement features 117a, 117b include, for example, grooves, protrusions, indents, projections, recesses, pins, rails or other components that assist in aligning the cartridge 100 within the image forming apparatus. The engagement features 117a and 117b also includes grooves, protrusions, indents, projections, recesses, pins, rails or other components that, for example, assist in coupling or attaching the cover 112 to the cartridge 100. For example, as illustrated in
The cover 112 can protect any components internal of the cover 112. The components internal of the cover 112, as will be discussed below and illustrated in
The dispense mechanism 200 includes a container side opening 204 configured to engage with the opening of the cartridge body 102. In an example, the dispense body 220 couples with the container side opening 204 by snap-fit, screwing, interlocking elements, or the like. The dispense body 220 is closed with a front surface 222, for example, to retain powder within the dispense body 220 during use.
The dispense body 220 includes a dispense opening 230 at a location, for example, different from the container side opening 204. As illustrated in
The dispense opening 230 and dispense port 232 are closed, for example, with a closing mechanism 240, such as a shutter, door, or other similar device (hereinafter “shutter”). The shutter 240 is configured to engage with corresponding features in the image forming apparatus. For example, the shutter 240 engages with the image forming apparatus via shutter engagement elements 241 such as with protrusions, recesses, or the like. The shutter engagement elements 241 are, for example, on at least one side of the shutter 240. Other locations of shutter engagement elements 241 are also contemplated, for example at a front or rear side of the shutter 240. For example, when the shutter 240 is properly engaged with the image forming apparatus, the shutter 240 is moved to open the cartridge 100 and provide a path for powder to be dispensed from the cartridge 100. In an example, the shutter 240 is moved longitudinally (e.g., in a similar direction to the length of the cartridge 100). The shutter 240, in another example, is rotated open or moves laterally with respect to the longitudinal direction of the cartridge 100. The shutter 240 movement is guided, for example with engagement between the shutter engagement elements 241 and at least one shutter groove, guide, rail, channel, track or the like 243 (see

In an example, the coupling mechanism 210 is removably coupled with the dispense body 220. In another example, the coupling mechanism 210 is secured to the dispense body 220. In such an example, the coupling mechanism 210 is coupled with the dispense body 220 with cooperation between shuttles 242 and 244 and grooves 250a and 250b. In another example, the coupling mechanism 210 is coupled along both sides 221a and 221b of the dispense body 220, each coupling member side portion 212a, 212b is optionally identical, substantially similar or different in design. In the example shown in
The coupling mechanism 210, in an example, has a bridge 216 that extends across a portion of the dispense body 220. In one example, the bridge 216 connects the coupling member side portions 212a and 212b together. The bridge 216 extends over or across a portion, or all of, of the proximal end 206 of the coupling mechanism 210. In another example, the bridge 216 extends over or across an area proximate to the proximal end 206. As illustrated in the example shown in FIGS. 3A and 3B, the bridge 216 extends over or across an area proximate to the proximal end 206.

In an example, as illustrated in
The dispense biasing member mount 246 and the coupling mechanism mount 247, in an example, are aligned so the biasing member 248 is coupled with one end 248a of the biasing member 248 coupled to the dispense biasing member mount 246 and another end 248b of the biasing member 248 coupled to the coupling mechanism mount 247. In an example, the biasing member 248 assists in controlling the movement of the coupling mechanism 210 or to assist in minimizing displacement of the coupling mechanism 210 in a lateral direction.
As illustrated in the examples shown in
While there are two coupling extensions 270 shown in the examples illustrated in
In an example, the coupling extensions 270 are arranged so the corresponding elements in the image forming apparatus rest on, between, or against at least one of the plurality of coupling extensions 270 without the corresponding elements of the image forming apparatus becoming disengaged during use. For example, if there are two coupling extensions 270 the corresponding elements in the image forming apparatus can rest on or between a first coupling extension 270a and a second coupling extension 270b. In another example, the corresponding elements in the image forming apparatus can pass over the first coupling extension 270a and rest against the second coupling extension 270b.
