Sheets fed out of a cassette supporting the sheets by a pickup roller are separated and fed by a sheet separation feeding unit having a feed roller and a separating roller which is rotatable in a direction opposite to a sheet feeding direction. A charge eliminating mechanism for eliminating charges of the separating roller is arranged on the upstream side in the sheet feeding direction in a separation nip portion between the feed roller and the separating roller.

In a NAT type determination method pursuant to RFC 3489, address information added in a binding response from a STUN server in response to a binding request issued in a latest transmission test is compared with address information added in a binding response in response to any transmission test executed therebefore. When the address information are not identical, a NAT type is determined symmetric. Even when a router whose NAT type changes frequently according to a use status is connected, communication is capable without manual setting change by a user.

An inexpensive fluorescent object is provided which may be used, for example, as a test object for color adjustment of a fluorescent endoscope system. The fluorescent object generates fluorescence while minimizing the generation of ‘noise’ at undesired wavelengths, and is made using a plastic that substantially does not deteriorate upon exposure to U.V. and visible radiation. A method of producing the fluorescent object is disclosed, namely, a plastic powder (such as PTFE) and an inorganic fluorescent powder (such as Mn-doped ZnS) are blended so as to form a mixture of these components, and the mixture is then molded by applying pressure to the mixture. An important feature of the invention is that heat is not added during any phase in the production of the fluorescent object, thereby preventing the inorganic fluorescent powder from being denatured when producing the fluorescent object.

To provide a sheet conveying apparatus capable of enhancing an accuracy of correcting a skew of a sheet, and of preventing position shift of a sheet. The present invention provides a sheet conveying apparatus for conveying a sheet by a sheet conveying unit disposed along a sheet conveying path, including: a skew detection sensor for detecting a skew of the sheet with respect to a sheet conveying direction by a plurality of detection sensors disposed in a direction intersecting perpendicularly the sheet conveying direction; and a skew correction roller adapted to be pivotally moved in a direction of correction of a skew of the sheet in a state with the skewed sheet being held on the basis of a detection signal from the skew detection sensor, in which one of the plurality of detection sensors of the skew detection sensor is disposed nearly on an extension line from a pivotal movement center of the skew correction roller in the sheet conveying direction.

A sheet feeding apparatus for feeding sheets supported by sheet stacking means capable of ascending and descending by sheet feeding means is provided. The sheet feeding apparatus includes sheet position detection means for detecting that an upper surface of a sheet stack supported by said sheet stacking means reaches a position whereat it can be fed by said sheet feeding means, blowing means for blowing air on an end portion of sheets stacked on said sheet stacking means, and control means for controlling said blowing means, wherein at least, either when it has been detected by said sheet position detection means that the sheets reach a position whereat they can be fed, or before a sheet feeding operation by said sheet feeding means is started, said control means performs a blowing operation by said blowing means during predetermined time.

A sheet feeding apparatus is provided with a sheet stacking device for stacking sheets thereon, a sheet feeding device for feeding the sheets stacked on the sheet stacking device, and a heating device for heating the sheets stacked on the sheet stacking device. The heating device is designed such that of the heat generating areas of the heating device, the heating value of the heat generating area for the central portion of the sheets stacked on the sheet stacking device is greater than the heating values of the other heat generating areas.

It is one objective of the present invention to provide a sheet feeding apparatus that can steadily separate and feed individual sheets without causing an image detect, such as a transfer failure. The sheet feeding apparatus, for employing a sheet feeding portion to feed sheets stacked on elevatable sheet stacking means, includes an air blowing portion for blowing air against an end face of a sheet stack supported by the sheet stacking means, a sheet position detector for detecting that a top face of the sheet stack has reached a position whereat a sheet feeding operation by the sheet feeding portion is enabled, wherein, when the sheet position detector has detected that the top face of the sheet stack has reached the position for sheet feeding, or when the sheet feeding portion starts the sheet feeding operation, and when a sheet is not actually fed after a predetermined waiting time has elapsed, the air blowing portion starts an air blowing operation during a predetermined air blowing period.

To provide a sheet conveying apparatus capable of improving a correction accuracy for conveying a sheet. Accordingly, a “sheet conveying apparatus for conveying a sheet using a sheet conveying unit arranged along a sheet conveying path” according to the present invention includes a skew detecting unit for detecting skew of the sheet conveyed along the sheet conveying path with respect to a sheet conveying direction, a skew correcting unit that moves in a direction for correcting the skew of the skewed sheet with the sheet nipped therein on the basis of a detection signal from the skew detecting unit, and a guide unit for regulating side edges of the sheet and guiding the sheet to the skew correcting unit, in which, when the skew correcting unit moves in the direction for correcting the skew of the sheet, the guide unit is moved in the direction for correcting the skew of the sheet.
