Office Action

§102 §103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1, 2, 5, and 6 are rejected under 35 U.S.C. 102(A)(1) as being anticipated by Stemmle US 5,201,517 (“Stemmle”). Regarding claim 1, Stemmle disclosed a media ejecting apparatus comprising: an ejection roller (25) to eject a medium; a first ejection tray (14) located below the ejection roller; a second ejection tray (17) located above the ejection roller; a guide (including one roller 27 seen in Figure 3) located in a vicinity of the ejection roller and rotatable around a rotation shaft of the ejection roller between a first position to guide the medium ejected by the ejection roller toward the first ejection tray and a second position to guide the medium ejected by the ejection roller toward the second ejection tray (see Figure 1); a driving mechanism including a motor (M2) to move the guide between the first position and the second position; and control circuitry (including 22) configured to control the driving mechanism, wherein the guide located at the second position guides the medium between the ejection roller and the guide to the second ejection tray (see Figure 1). Regarding claim 2, Stemmle disclosed another motor (M1) to drive the ejection roller. Regarding claim 5, Stemmle disclosed an assist roller (another of rollers 27 seen in Figure 3) located above the ejection roller and facing the ejection roller, wherein the assist roller assists the ejection roller in ejecting the medium to the second ejection tray (Figure 1). Regarding claim 6, Stemmle disclosed an imaging device (10); and a sensor (50) located upstream from the imaging device in a media conveyance direction, wherein the control circuitry is further configured to: determine whether the medium conveyed is a separator medium based on an output signal from the sensor; and control the driving mechanism to change a position of the guide based on a determination indicating whether the medium conveyed is the separator medium (see at least col. 1, line 46 – col. 2, line 3; and col. 5, lines 49-54). Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 3 and 4 are rejected under 35 U.S.C. 103 as being unpatentable over Stemmle in view of Weijers US 5,924,688 (“Weijers”). Stemmle disclosed the limitations of claim 1 as listed above and further that the guide includes a rotation shaft (26), and that the driving mechanism further drives the ejection roller (see col. 9, lines 5-15), but does not teach using an interrupter as claimed. Weijers teaches an interrupter located between a guide (3) and rotation shaft (5) of the guide, and the interrupter interrupts a driving force generated from a motor and transmitted to the rotation shaft of the guide for a predetermined period of time (Figures 1-4). The rotation shaft of the guide includes a protrusion (20), the interrupter includes a cam (10) fixed to the guide, the cam includes a space for the protrusion to rotate and a contact portion (13) located in the space, and the interrupter further interrupts the driving force generated from the motor and transmitted to the rotation shaft of the ejection roller until the protrusion rotates to contact the contact portion in the space (Figures 1-4). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to use an interrupter arrangement as taught by Weijers within Stemmle as a well-known way to mechanically cause a timing delay to ensure proper timing for directional changes when varying sheet destinations.
