A filter frame includes a first frame portion that includes a filter installation surface for installing a filter, a second frame portion that retains the filter by holding the filter between the first frame portion, and a hinge portion that connects the first frame portion and the second frame portion. The first frame portion has a plurality of fitting projections and an arm provided on a filter installation surface of the first frame portion so as to extend between a plurality of fitting projections. The second frame portion has a plurality of fitting portions for receiving the plurality of fitting projections, and a cutout provided in a side of the frame facing the side in which the second frame portion is connected to the first frame portion by the hinge portion.

A one-way clutch includes: an inner ring provided with an inserting opening for permitting insertion of a rotation shaft and rotatable integrally with the rotation shaft by being engaged with the rotation shaft; an outer ring engaged with an outer peripheral surface of the inner ring and rotatable in one direction relative to the inner ring and non-rotatable in a direction opposite to the one direction; and an elastic metal plate member, engaged with the inner ring, for limiting movement of the inner ring relative to the outer ring in a rotational axis direction of the outer ring. When the rotation shaft is mounted in the inner ring, the elastic metal plate member includes a leaf spring portion positioned and elastically deformable in a gap between the rotation shaft and the inner ring.

One-way clutch and sheet feeding roller

A filter frame for holding a filter provided with a plurality of folds so as to alternately form ridges and troughs includes: a first frame portion including a first holding portion, having a side corresponding to a first side of the filter, for holding the filter; a positioning portion, provided on the first holding portion, for determining a position of the filter; and a second frame portion including a second holding portion for holding the filter by sandwiching the filter between the first and second holding portions. The second holding portion is provided so as to be capable of opposing the first holding portion via the filter and has a side corresponding to a second side of the filter.

Filter frame

A sheet feeding apparatus includes a sheet stacking unit, a suction conveyance unit configured to convey an uppermost sheet stacked on the sheet stacking unit, a suction unit configured to adsorb the sheets onto the suction conveyance unit, and an adsorption completion detection unit. In the sheet feeding apparatus, when the tab-attached sheets are stacked on the sheet stacking unit and fed such that their tab portions are on the downstream side in a sheet feeding direction, the suction unit starts to adsorb the sheet and the suction conveyance unit starts to convey the sheet immediately after the adsorption completion detection unit detects the completion of the adsorption. When the sheets other than the tab-attached sheets are fed, the suction unit previously adsorbs the sheet onto the suction conveyance unit, and the suction conveyance unit starts to convey the sheet in response to the sheet feeding signal.
