Abstract: In one aspect of a sheet conveying device, a sheet member is guided from a sheet feeding port through a reading position to a terminal end positioned above the sheet feeding port on a first path, guided from the terminal end through the reading position to the terminal end again on a second path, and guided from the terminal end through the reading position to a sheet discharging port on a third path. A transfer member rotates a conveying member and halts the rotation of the conveying member respectively according to first and second rotations of a driving source. A first detecting unit is provided downstream of the sheet feeding port on the first path. A control unit switches the driving source from the first rotation to the second rotation on the basis that the first detecting unit detects a trailing end of the sheet member.

Abstract: A method and system for analyzing a problem in a computing environment. Symptom rules that include associated problem information are generated in a symptom catalog. An input file including a stack trace provided in response to detecting the problem is received. Function names included in contiguous lines in the stack trace are identified. In response to a search for the function names in the symptom catalog, the function names found in the search are matched to keywords included in a symptom rule. The computing system retrieves problem information that corresponds to the matched keywords. A report is generated that includes the stack trace and a solution included in the retrieved problem information. The generated report uses a text attribute to emphasize the text of the function names included in the stack trace.

Each of the first and second detecting unit includes: an arm member rotatably supported to take a posture where the arm member projected from the guide face to the conveying path and a posture where the arm member is retracted from the conveying path by rotating toward the guide face; and a first sensor that outputs a signal depending on the posture of the arm member.

Abstract: A document feeding device for feeding documents comprises a document input tray on which documents to be fed are placed, a document output tray to which the documents are ejected, and a feeding mechanism which is provided for a feeding path connecting the document input tray and the document output tray via a scanning position and feeds each document from the document input tray to the scanning position and from the scanning position to the document output tray.
