A ribbon feed path may be defined proximate the ribbon positioning assembly between a first spool and a second spool of the ribbon cartridge, and the printhead assembly may be driven between the first spool and the second spool in response to the lid moving from an open position to a closed position. The printhead may engage the ribbon as the printhead assembly is driven between the first spool and the second spool, and the printhead may drive the ribbon to a ribbon printing path.
According to some embodiments, the base may define a media receiving area configured to be accessible when the lid is in the open position and inaccessible when the lid is in the closed position. When the lid is in the open position and the ribbon positioning assembly in the accessible position, a center of gravity of the printer may be defined proximate the base of the printer relative to the lid and the ribbon positioning assembly. The lid may be hingedly attached to the base proximate a back of the printer and the ribbon positioning assembly may be pivotably attached to at least one of the lid or the base proximate the back of the printer.

The printhead assembly may include a printhead, and in response to the lid moving from the open position to the closed position, the printhead may move into a position in which the second spool is positioned substantially between the printhead and the lid. The printhead assembly may further include a convex deflector assembly and the printhead assembly may define a print line where the printhead engages the platen roller. The convex deflector assembly may be positioned upstream of the print line relative to a media feed path. The convex deflector assembly applies tension across a width of the ribbon, parallel to the print line to remove wrinkles from the ribbon as it moves along a ribbon printing path.
According to another example embodiment of the present invention, a ribbon cartridge is provided that includes a first spool housing configured to receive a first spool, a second spool housing configured to receive a second spool, and at least one frame member extending between the first spool housing and the second spool housing. A locking feature defining a locked position and an unlocked position adapted to lock the ribbon cartridge within a ribbon positioning assembly may also be provided. The ribbon cartridge may further include a spool lock, where the spool lock is configured to engage at least one of the first spool or the second spool in response to the ribbon cartridge not being received within a ribbon positioning assembly. The spool lock may be configured to disengage the at least one of the first spool or the second spool in response to the ribbon cartridge being received within a ribbon positioning assembly. The spool lock may be configured to engage both the first spool and the second spool in response to the ribbon cartridge not being received within a ribbon positioning assembly, and the spool lock may be configured to maintain a tension of a ribbon extending between the first spool and the second spool when the spool lock is engaged with the first spool and the second spool. The first spool may be a ribbon supply spool and the second spool may be a ribbon take-up spool, where a radio frequency identification chip may be disposed proximate the take-up spool.
According to some embodiments, the frame member extending between the first spool housing and the second spool housing may define a recess, where the recess of the frame member is defined by an area of the frame member that is narrower than a majority of the frame member. The frame member may include additional structural reinforcement proximate the recess relative to the majority of the frame member.
Another example embodiment of the present invention may provide a printer that includes a base and a lid hingedly attached to the base and moveable between a closed position in which the lid is secured to the base, and an open position. A cavity may be defined between the lid and the base, where the cavity may be inaccessible when the lid is in the closed position, and the cavity is accessible when the lid is in the open position. The printer may further include a ribbon positioning assembly disposed within the cavity that is pivotably attached to at least one of the lid or the base, where the ribbon positioning assembly may be configured to move between a printing position when the lid is in the closed position, and an accessible position when the lid is in the open position, where the ribbon positioning assembly includes a first pair of guide channels configured to receive therein a ribbon cartridge, and a second pair of guide channels. The printer may include a printhead assembly attached to the lid, where the printhead assembly engages the second pair of guide channels and translates within the guide channels in response to the lid being moved between the closed position and the open position.
According to some embodiments, the printhead assembly may be pivotably attached to the lid. The printhead assembly may move along the second pair of guide channels to a disengaged position relative to the ribbon positioning assembly in response to the lid moving to the open position, and the printhead may move along the second pair of guide channels to an engaged position relative to the ribbon positioning assembly in response to the lid moving to the closed position. The printhead assembly may be disposed at a first angle relative to the lid in the disengaged position, and the printhead assembly may be disposed at a second angle relative to the lid, different from the first angle, in the engaged position. The base may include a platen roller, and in response to the lid being moved from the open position to the closed position, a printhead of the printhead assembly may be brought into engagement with the platen roller.
According to some embodiments, the printer may include a ribbon feed path defined proximate the ribbon positioning assembly between a first spool and a second spool of the ribbon cartridge, and the printhead assembly may be driven between the first spool and the second spool in response to the lid moving from an open position to a closed position. The printhead may engage the ribbon as the printhead assembly is driven between the first spool and the second spool.
According to another embodiment of the present invention, a printer may be provided including a base, a platen assembly supported proximate the base, a lid hingedly attached to the base movable between a closed position in which the lid is secured to the base, and an open position, and a ribbon positioning assembly. The ribbon positioning assembly may be disposed within the cavity and may be pivotably attached to at least one of the lid or the base, where the ribbon positioning assembly is configured to move between a printing position when the lid is in the closed position, and an accessible position when the lid is in the open position, where a media access gap is defined between the ribbon positioning assembly and the platen assembly for accessing a media supply. The media access gap may be sized to receive there through a supply of media. In response to the ribbon positioning assembly being moved to the closed position, the media access gap may be closed to define a media feed path along which media travels during printing. In response to the ribbon positioning assembly being moved to the closed position, at least a portion of the media and at least a portion of the ribbon are captured between a printhead and the platen assembly.
Having thus described the invention in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
Printers and media processing devices may be configured to print and/or encode media drawn from a roll or spool. Such media may include a web supporting a plurality of individually cut media components, such as adhesive-backed and carrier-supported labels, or the media may be a continuous web such as a spool of linerless label media or direct thermal media. Printers process (e.g., print, encode, etc.) the media by drawing the media from the spool and routing the media proximate various processing components (e.g., printhead, RFID reader/encoder, magnetic stripe reader/encoder etc.). Processing the media from a spool may facilitate a continuous or batch printing process.
From time to time, printers exhaust the available supply of media such that a user must replace the media supply spool. Other consumables such as ribbon or ribbon cartridges, printheads, and the like must also be periodically replaced. Replacing consumable components of a media processing device can often be complex and arduous, with the time to replace such components resulting in costly downtime of the media processing device. Replacement of consumable components can be even more difficult for media processing devices of relatively small form factors, such as desktop or mobile printers, as the components are generally tightly packaged into a relatively small housing. As such, it may be desirable for a media processing device to provide easy access to the consumable components therein to facilitate relatively quick and easy replacement of consumable components, particularly for a media processing device including a small form factor.
Embodiments of the present invention are directed to an improved media processing device that is structured to enhance user serviceability and simplify replacement of consumable components. Such embodiments are configured to provide these advantages while maintaining a compact size.
The media processing device 100 of
Within the cavity 140 of example embodiments may be a media receiving area in which a spool of media 150 may be received. A media spool 150 may be received, for example, on a media spindle 155 as shown in
Referring back to
The printhead assembly 210 may further include a ribbon-out sensor 213 configured to detect a ribbon-out condition or a ribbon-missing condition. The ribbon-out sensor 213 is arranged with a line-of-sight 214 of the ribbon 189 as it advances along the ribbon feed path 190. The ribbon-out sensor 213 is configured to detect a specific ribbon material that is disposed at the end of the ribbon such that as the ribbon is consumed, upon reaching the end of the ribbon, the specific ribbon material is drawn along the feed path 190 and is detected by the ribbon-out sensor 213. This specific ribbon material may include a metallic material that is reflective such that the ribbon-out sensor 213 may detect a predetermined amount of reflected light to signal to the ribbon-out sensor 213 that the ribbon 189 has been consumed. Upon detection of the ribbon-out condition by the ribbon-out sensor 213, a signal may be sent to the media processing device controller to indicate that printing must be stopped until the ribbon is replaced.
The ribbon-out sensor 213 may also be configured to detect a ribbon-missing condition. The media guide 230, which will be described further below, may include a surface 215 that mimics the specific ribbon material that indicates a ribbon-out condition. For example, if the specific ribbon material is a metallic, reflective material, the surface 215 may include a mirror or material with similar properties as the specific ribbon material. This surface 215 may mimic the ribbon-out condition when a ribbon cartridge 160 is not installed in the media processing device 100. Thus, when the surface 215 is detected by the sensor 213, a ribbon-out condition is sensed and printing is not permitted. Further, this ribbon-out or ribbon-missing condition can be used in conjunction with an RFID sensor configured to detect the RFID chip of a ribbon cartridge 160. In order for the media processing device to allow printing, the sensor 213 must not detect a ribbon-out or ribbon-missing condition, and the RFID sensor must detect a properly authenticated RFID chip of a ribbon cartridge. The authentication of the RFID chip may be performed by a media processing device controller, which may also determine the media processing device cartridge 160 type, printing properties (e.g., printhead temperature, speed, etc.).
Embodiments of the present invention may provide a media processing device that remains stable when the lid 120 is in the open position and the ribbon positioning assembly 220 is moved to the accessible position. The center of gravity of the media processing device may be low and proximate a mid-point between the front of the media processing device 100 and the back of the media processing device when the lid 120 is in the closed position. In the open position, the center of gravity may be shifted toward the back of the media processing device, but the center of gravity may remain within the middle third of the media processing device along its length, and the center of gravity may remain low, positioned substantially within a cavity defined by the base 110 and below an upper perimeter edge defined by the base. Positioning the center of gravity within the base 110 may maintain a stable media processing device balance during loading/unloading of consumables from the media processing device 100.
In the accessible position, with the lid 120 in the fully opened position, the ribbon positioning assembly 220 may provide access to the ribbon cartridge 160 to allow the ribbon cartridge to be removed from and/or replaced within the ribbon positioning assembly. As will be further detailed below, the ribbon cartridge 160 may include aligning features and the ribbon positioning assembly may include complementary aligning features defined by the first and second side rails 161 of the ribbon cartridge which allow the ribbon cartridge to be received in a repeatable and accurate position within the ribbon positioning assembly, as will be described further below. The slots in the ribbon positioning assembly 220 into which the cartridge slides in provide very accurate positioning controls for the cartridge within a tight tolerance. The hard stop at the end slot of the ribbon positioning assembly 220 give a very reliable position to the cartridge each and every time it is inserted.
When the lid 120 is in the open position of
As noted above, media processing devices according to the present invention may be configured to process various media widths. Thus, it may be desirable to have an inner limit stop that is adjustable. Thumbwheel 159 may be configured to help accomplish this.
Embodiments of the present invention may further include a platen 250 disposed along the media feed path configured to be engaged by the printhead 200 when the lid 120 is in the closed position. The media and the ribbon are configured to be received between the nip defined between the printhead 200 and the platen 250 as illustrated in
In order to facilitate loading and unloading of the ribbon cartridge 160 into the ribbon positioning assembly 220, the printhead 200 may be disengaged from the ribbon 193 and the ribbon cartridge 160 in response to the lid 120 being moved to the open position, and the ribbon positioning assembly 220 being moved to the accessible position.
As illustrated, while the lid 120 is in the open position relative to the base 110, and the ribbon positioning assembly 220 is in the accessible position as illustrated in
The ribbon positioning assembly 220 includes various positioning features that ensure proper alignment between components of the media processing device. The ribbon positioning assembly 220 includes first and second sidewalls (described further below), that are structured to receive and support the ribbon cartridge 160. The first and second sidewalls may be joined together by structural support members that rigidly tie together the sidewalls to create a ribbon receiving cavity between the sidewalls. The media guide 230 may serve as one of the structural supports that ties the sidewalls together.
Further, the ribbon positioning assembly 220 may include guides that direct the movement of components when the lid 120 is moved between the open position and the closed position.
According to the illustrated embodiment of
A raised member, such as projection 239 of
According to some embodiments of the present invention, an additional alignment feature may be included to align the ribbon cartridge 160 to the ribbon positioning assembly 220. This alignment feature may include a recess 242 disposed within the ribbon cartridge 160, and the ribbon positioning assembly 220 may include a pin configured to be received within the recess. The recess may be of any shape; however, a round shape may be desirable as the pin of the ribbon positioning assembly may then include a rounded shape with a tapered point, in order to promote self-alignment of the ribbon cartridge 160 with the pin as the ribbon cartridge is fully installed within the ribbon positioning assembly 220.
Referring back to
As illustrated in
Referring back to
The lid 110 may further include one or more projections 167 disposed inside the lid configured to engage the ribbon cartridge 160 upon the lid being moved to the closed position. The one or more projections 167 may be configured to ensure the ribbon cartridge 160 is fully seated in the ribbon cartridge guide channel 234, thereby ensuring that the ribbon cartridge spools are properly engaged with the ribbon drive gears described further below. The one or more projections 167 may also preclude movement of the ribbon cartridge 160 during movement of the media processing device 100 by precluding any fore/aft movement of the ribbon cartridge 160, supplementing the security provided by the detent engagement of the printhead 160 within the printhead positioning assembly 220. The one or more projections 167 further ensure that the appropriate ribbon cartridge 160 is used. If a ribbon cartridge 160 cannot be properly seated within the ribbon cartridge guide channel 234, the projection 167 will preclude the lid 120 from closing properly, and prevent operation of the media processing device 100.
In the example embodiment described above with respect to
The mechanism by which the printhead is advanced between the first spool 170 and the second spool 180 and advanced to the printing position of
When the consumables of the media processing device 100, such as the ribbon cartridge 160 or the media 150, need to be replaced, the lid 120 of the media processing device needs to be moved to from the closed, printing position of
In response to the lid 120 being moved from the closed position to the open position, the printhead 200 becomes disengaged from the ribbon 193 and is moved out from between the first spool 170 and the second spool 180 of the cartridge 160, along the printhead assembly guide channel 242 from the bottom 246 to the top 244. In this manner, undesirable slack in the ribbon 193 may remain, such as when the length of ribbon exposed between the first spool 170 and the second spool 180 is sufficient for the length of ribbon printing path 190, but is not necessary when the printhead 200 is disengaged from the ribbon 193, leaving excess ribbon between the first spool 170 and the second spool 180. As such, it may be desirable to remove the slack from the ribbon 193 when the lid 120 is moved to the open position, the ribbon positioning frame 220 is moved to the accessible position, and the printhead 200 is disengaged from the ribbon 193.
Embodiments of the present invention may include a ribbon tensioning mechanism 300 as visible in
Tensioning mechanisms 302 and 304 may each include a driven gear that is coupled to the gears 310 of the gear train and a drive gear that is coupled to a respective one of the gears 172, 182 of the first spool 170 and the second spool 180. Between the driven gear and the drive gear of each tensioning mechanism 302, 304 may be a torsion spring and a clutch. In this manner, as the pinion gear drives gears 310 of the gear train, the driven gears of the tensioning mechanism are driven. The torsion spring of each tension mechanism 302, 304 is wound until a threshold force is achieved, at which time force is transmitted across the clutch of each tension mechanism 302, 304 to the drive gear of each tension mechanism, which drives the gears 172, 182 of the ribbon spools. During the process of printing, the torsion springs within the first and second tension mechanisms 302, 304, start to wind up and reach a maximum tension. This mechanism pre-loads the torsion springs of the tension mechanisms 302, 304 during printing and holds that pre-loaded torsion force during printing. While the illustrated embodiments include a ribbon cartridge, the tension mechanisms may also be used for a non-cartridge ribbon embodiment, such as with independent ribbon spools. The tension mechanisms help to minimize wrinkling of the ribbon which can lead to reduced print quality as the tension mechanisms apply tension during printing, while the tension mechanisms 302, 304 are preloaded, and maintain tension on the ribbon to keep the ribbon from folding over on itself when the printhead is disengaged from the ribbon.
In response to a user releasing a latching mechanism and opening the lid 120 of the media processing device 100 from the closed position to the open position, and the ribbon positioning assembly 220 is moved from the inaccessible, printing position to the accessible position, as shown in
As described above, tension across the ribbon 193 between the first spool 170 and the second spool 180 is facilitated by the tensioning mechanisms 302 and 304. The tensioning mechanisms are engaged with the gears 172, 182 while the ribbon cartridge 160 is received within the ribbon positioning assembly 220. In order to maintain tension on the ribbon 193 between the first spool 170 and the second spool 180 when the ribbon cartridge is removed from the ribbon positioning assembly 220, another mechanism may be necessary.
According to embodiments of the present invention, as illustrated in
Embodiments of the ribbon cartridge 160 according to some examples may include a snap feature 165 configured to aid in retaining the ribbon cartridge 160 in the fully installed position within the ribbon positioning assembly 220. The snap feature 165 may be structured in a variety of manners, but in the illustrated embodiment, the snap feature 165 includes a ridge on a flexible member 166 of the cartridge. The flexible member 166 biases the snap feature away from the spool 180. The flexible member enables the snap feature 165 to be pushed inward toward the second spool 180 when the ribbon cartridge is inserted into the cartridge channel 234. The cartridge channel 234 may include a recess 267 configured to receive therein the snap feature 165, as illustrated in
Installation of the ribbon cartridge 160 into the cartridge channel 234 may be relatively intuitive; however, in some instances, a user may not fully install the cartridge in the channel. For example, a user may not press the ribbon cartridge 160 far enough into the cartridge channel 234 for the snap feature 165 to engage the corresponding recess 267 of the cartridge channel. In such an instance, it may be desirable for the ribbon cartridge 160 to be configured to be driven from the partially installed position to the fully installed position.
While the above disclosed embodiments describe a ribbon positioning assembly 220 that is configured to receive a ribbon cartridge therein, embodiments of the invention may further be configured with ribbon positioning assemblies that are configured to receive loose ribbon spools that do not include a cartridge. In this manner, a second ribbon positioning assembly 222 may be interchangeable with the ribbon positioning assembly 220 configured to receive a ribbon cartridge, as illustrated in
The media used by media processing devices of example embodiments may be in a variety of forms. For example, media may be of the fan-fold variety as described above and may be used for processing tickets for travel, such as airline tickets. Media may also be continuous feed media that is perforated to enable separation of media units from the continuous roll of media. Still further, media may be an adhesive label that is carried by a carrier backing, where the carrier may include a release layer (e.g., a silicone layer), that enables an adhesive label to be peeled from the carrier after processing of the media. Embodiments where the media is an adhesive label may be used in shipping facilities or other locations where a label needs to be applied to a surface.
According to embodiments in which the media processing device is configured to process labels carried by a carrier backing, it may be desirable to peel the label from the carrier as the media exits the media processing device. In such embodiments, the present invention may include a modular peeling mechanism adapted to be removably installed on the media processing device.
Modular peel mechanism 500 may be configured to be installed to a media processing device by an end-user rather than, or in addition to being available to be installed during manufacture. In the illustrated embodiment, the modular peel mechanism may be snapped into place to replace a decorative fascia piece and may be held in place by one or more screws, with the preference being a small number, such as two, to facilitate easy installation and removal of the modular peel mechanism. The modular peel mechanism may further include an electrical connector to enable electrical connection of the modular peel mechanism 500 to the media processing device to enable certain functions of the modular peel mechanism, such as the label-taken sensor, as will be described further below. The electrical connector may be configured such that, upon installation of the modular peel mechanism 500 to the media processing device, the connector is received by the media processing device, and no additional connection step is required.
According to the illustrated embodiment of
In order to process and peel media labels from a carrier backing, it may be desirable to have a mechanism in place to alert the media processing device when a processed label has been removed by a user at the media exit 520. Absent some mechanism to alert the media processing device of the removal of a processed media label, a manual indication may need to be provided to the media processing device to avoid continuous processing and peeled media labels piling up and adhering to one another at the media exit 520. Embodiments of the modular peel mechanism disclosed herein may include a “media label taken” sensor 570 disposed proximate the media exit 520. The media processing device may process a media label until the processing is complete and the media label is ready to be retrieved by a user from the media exit 520. Until that media label is retrieved (i.e., while the media label taken sensor 570 detects the presence of a media label), the processing operation may be suspended. In response to a user or a media label applicator device retrieving the media label, the media label taken sensor 570 may detect that the media label was retrieved, and a subsequent media label may be processed and peeled, to be presented for retrieval.
While automated peeling during media processing as performed by the modular peel mechanism 500 described above is desirable, one drawback is the initial feeding of the modular peel mechanism 500 with the carrier backing 510 to initiate the peeling process. The initial feeding can be tedious, particularly when the carrier backing is not evenly torn or cut, and when the carrier backing must be fed through a relatively small opening or nip. In order to improve this process, embodiments of the modular peel mechanism 500 described herein may be configured to be pivotable, as illustrated in
In order to maintain consistent, even peeling of the carrier backing 510 from the media labels, a user may apply a pulling force to the carrier backing 510 as it exits the modular peel mechanism 500 along carrier path 550. However, such force can create a tension on the carrier backing 510 which would urge the modular peel mechanism 500 to the open/loading position. As such, embodiments of the present modular peel mechanism 500 may include a latch to hold the modular peel mechanism in the closed position illustrated in
