DETAILED DESCRIPTION
[0014] In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific examples in which the disclosure may be practiced. It is to be understood that other examples may be utilized and structural or logical changes may be made without departing from the scope of the present disclosure. The following detailed description, therefore, is not to be taken in a limiting sense. It is to be understood that features of the various examples described herein may be combined, in part or whole, with each other, unless specifically noted otherwise.
[0015] At least some examples of the present disclosure are directed to a scan assembly comprising a monolithic metal frame having an outer wall defining an interior frame portion. The interior frame portion has a scan region to support and at least partially house a scanning unit to be movable within and relative to the scan region. The interior frame portion also has a control region to support and at least partially house a control panel. The outer wall has a first face exposed to the interior frame portion and an opposite second face to be directly exposed to an external environment.
[0016] In some examples, adjacent at least the scan region, a height of the outer wall extends in a first orientation and at least a majority of the scan region extends in a second orientation generally perpendicular to the first orientation.
[0017] In some examples, the scan assembly may sometimes be referred to as a scan tub. In some examples, the scan assembly may be incorporated into a multi-function printer or other imaging device. In one aspect, the monolithic frame has a low profile in a vertical orientation of an imaging device while exhibiting torsional stiffness and mass, which reduces vibration and/or noise to enhance quiet scanning. Meanwhile, this low profile in the vertical orientation may enable compliance with Section 508 of American Disabilities Act (ADA) via achieving a lower overall height of the imaging device, whether as a desktop model or floor-standing model. In addition, the single piece metal frame provides strength to withstand large loads during handling and/or robust use.
[0018] Some commercially available scan tubs typically have multiple parts connected together, have a separate control panel frame and/or are made of plastic. In addition to a less elegant appearance, these arrangements lack the strength, stability, and/or low profile offered by at least some examples of the present disclosure.
[0019] As noted above, in some examples the scan assembly includes a scan region to support and at least partially house a scanning unit to be movable within and relative to the scan region. As previously noted, in some examples an outer wall of the metal frame of the scan assembly is exposed to an external environment. This arrangement may reduce manufacturing costs, while enhancing aesthetics.
[0020] These examples, and additional examples, are described in association with at least
[0021]
[0022] As further shown in
[0023]
[0024] As shown in
[0025] In some examples, at least the outer wall 23 of scan assembly frame 22 has a height (H1) while the printer frame 42 has a height (H2) relative to a bottom portion 49, which is provided for contact against a support surface. In some examples, the support surface may be a desktop while in some examples, the support surface comprises a cabinet to enable a floor standing arrangement for imaging device 40.
[0026] In some examples, together the scan assembly frame 22, the second frame 42, and lid 50 have a combined height of H4 inches and the scan assembly frame 22 has a width W1. In some examples, the low vertical profile of the scan assembly frame 22 may enable the overall height (H4) of the imaging device 40 to comply with user access specifications according to standards of the American Disabilities Act (ADA), such as but not limited to, standards identified in Section 508 of the ADA.
[0027] In some examples, the scan assembly frame 22 is made of aluminum and/or aluminum alloys while in some examples, the metal scan assembly frame 22 is made from other lightweight, strong, formable metal material(s). In some examples, the scan assembly frame 22 is made of other lightweight, strong non-metal materials that are moldable or formable as a single, unitary piece.
[0028]
[0029] In some examples, both the first recessed portion 140 and the second recessed portion have a length substantially the same as length L1 of the scan assembly frame 22. As further shown in
[0030] In some examples, the scan unit 120 comprises a drive unit 126, a scanbar 124, and a guide 128. In some examples, the scan unit 120 comprises and/or incorporates a contact image sensor (CIS) to implement scanning functions to obtain a scanned image of an object or document placed onto a scan surface 131 above scan region 24.
[0031] In some examples, scan assembly 100 includes a scan surface 131 covering scan region 24, as schematically represented in the partial sectional view of
[0032] The guide 128 has a length that extends in the first orientation (Y) and which is substantially the same as the length L1 of the scan region 22. The scanbar 124 extends in a second orientation X generally perpendicular to the first orientation Y and generally perpendicular to a longitudinal axis of the guide 128. In some examples, the scan bar 124 has a length L3 which is substantially the same as or slightly less than a width W2 of the scan region 24. The drive unit 126 has a length generally corresponding to a width W4 of the first recessed portion 140 of scan region 22. Meanwhile, control region 26 has a width W3.
[0033] The drive unit 126 is sized and shaped to fit within the first recessed portion 140 and therefore to be at least partially housed within the first recessed portion 140, as further later illustrated in association with at least
[0034] In some examples, in at least the scan region, the outer wall 23 defines a side portion 27A of the scan assembly frame 22 and the outer wall 23 defines two opposite ends 150A, 150B of the scan assembly frame 22. In some instances, the side 27A of the scan assembly frame 22 also may referred to as a back portion of an imaging device 40 when the control panel 110 is referred to as being located at a front portion of the imaging device 40.
[0035] In one aspect, the two opposite ends 150A, 150B of scan assembly frame 22 define end walls of scan region 24, while the side 27A of scan assembly frame 22 defines a first side wall of scan region 24. In one aspect, a combination of the side 27A of outer wall 23, of portions 143A, 143B of outer wall 23 (partially defining the ends 150A, 150B of scan region 24), and of a first bottom panel 147 at least partially defines the first recessed portion 140 of the scan region 22, as shown in
[0036] In one aspect, a combination of the boundary 145, of portions 145A, 145B of outer wall 23 (partially defining the ends 150A, 150B of scan region 24), and of a second bottom panel 148 at least partially defines the second recessed portion 142 of the scan region 22, as shown in
[0037] In some examples, control region 26 includes a third recessed portion 160. In some examples, the third recessed portion 160 is centered relative to opposite ends 161A, 161B of the control region 26, and therefore corresponds to a central portion of the control region 26. In some examples, the third recessed portion 160 has a length (L2) less than one-half of a length (L1) of the control region. In some examples, a control panel 110 is mountable within and relative to the third recessed portion 160 to be sandwiched between two outer portions 163A, 163B on opposite sides of control panel 110. In some examples, the two outer portions 163A, 163B have recessed structures (e.g. a ledge 382A in
[0038]
[0039] A vertical wall defines boundary 145 between the first and second recessed portions 140, 142. The depth H5 of the first recessed portion 140 is equal to or greater than a combined height H9 of the drive unit 126 and scan bar 124, while the depth H6 of the second recessed portion 142 is equal to or greater than a height (H10) of the scan bar 142. Accordingly, in some examples, the first recessed portion 140 at least partially houses the drive unit 126 and a first portion 125A (
[0040] As further shown in
[0041] In some examples, in at least scan region 24, the outer wall 23 has a uniform height H1 extending between top edge 212A and bottom edge 214A.
[0042] As noted elsewhere, in some examples, the depth H5 of the first recessed portion 140 is no more than 110 percent to 130 percent of the height H1 of the outer wall 23 of the scan assembly frame 22.
[0043] In some examples, a distance H8 between the first bottom panel 147 and a bottom edge 214A of outer wall 23 identifies the extent to which the first recessed portion 140 extends vertically below and protrudes beyond the bottom edge 214A of outer wall 23 in at least the scan region. As noted elsewhere, in some examples, this protruding portion may extend downward into an interior of a printer frame (42 in
[0044] In some examples, in a manner similar to border 157 in
[0045] In some examples, the border 257 has a thickness H11. In some examples, this thickness H11 is less than a height H1 of the outer wall 23 of the scan assembly frame 22. In some examples, the border 257 has a top surface 258 which extends in generally the same plane as a top edge 212A of the outer wall 23.
[0046] However, in some examples, a top edge 258 of the border 257 is spaced apart (e.g. recessed) from the top edge 212A of the outer wall 23 by a distance no more than a thickness of the scan surface 131 extending over scan region 24.
[0047] In some examples, a bottom edge 259 of border 257 is spaced apart by a distance H12 from a bottom edge 214A of outer wall 23.
[0048] As previously noted in association with
[0049] In some examples, the third recessed portion 160 includes a bottom panel 370. As shown later in association with at least
[0050] In some examples, a bottommost portion 374 of the bottom panel 370 of the third recessed portion 160 extends beyond (i.e. protrudes from) the bottom edge 214B of the outer wall 23 in at least the control region 26. This arrangement, in turn, enables a top surface 280 of control panel 110 to be flush with a top surface of adjacent covers (250A, 250B in
[0051] As shown in
[0052] With further reference to at least
[0053] With further reference to at least
[0054] In some examples, in at least the scan region 24, the interior frame portion 29 omits freestanding vertical walls or horizontally extending protrusions to enable free movement of scan unit 120 throughout substantially the entire length L1 and width W2 of the entire scan region 24.
[0055] In some examples, the scan unit 120 is sole active imaging component contained within scan region 22.
[0056]
[0057] The frame 302 has an outer wall 323 defining an interior frame portion 315, which has a scan region 324 and a control region 326. In a manner similar to
[0058] As further shown in
[0059] As further shown in
[0060] As further shown in
[0061] With further reference to at least
[0062] In some examples, the wall portion 350 of the first bottom panel 347 may be at least partially defined by a plurality of spaced apart struts like struts 362A, 362B of second bottom panel 348.
[0063] As shown in
[0064] Via this arrangement, in some examples no non-metal covering (e.g. plastic support layer) is interposed between the metal frame 302 and the scan unit 120 and no non-metal covering (e.g. plastic support layer) is interposed between the metal frame 302 and a scan surface (e.g. 131 in
[0065] In some examples, internal components such as scan unit 120 are directly coupled to metal frame 302, such that no non-metal layer (e.g. plastic support layer) is interposed between the scan unit 120 and the scan region 324 of the metal frame 302. It will be understood that, in at least some examples, the term directly coupled does not exclude fasteners but indicates that a non-metal (e.g. plastic, etc.) sheet or other structure does not form a layer over the metal frame.
[0066] In some examples, the outer wall 323 is seamless such that at least an outer face 35 of the outer wall 323 defines a continuous surface lacking seams or other visible discontinuities.
[0067]
[0068] In one aspect, in the control region 326,
[0069]
[0070]
[0071]
[0072] In some examples, first portion 446 has a width W5 and height H15, while second portion 447 has a width W6 and a height (e.g. thickness) H14. The overall height of printer frame 442 is represented as H2.
[0073] Via this arrangement, the imaging device includes a direct support region 502 and a non-direct support region 504 as shown in
[0074]
[0075] In the non-direct support region 504 shown in
[0076] In some examples, at least a portion of the non-direct-support region 504 is co-extensive with at least a portion of scan region 24, as shown in
[0077] Accordingly, as shown via
