    摘要： A sheet thickness detecting device for detecting the thickness of a recording member precisely irrespective of accuracy of parts is disclosed. A state that a roller 1 of a pair of rollers 1, 2 is positioned at a predetermined angle of rotation, is detected by a flag 11 fixed to the axle of the roller 1 and a photosensor 12 for roller rotation angle detection. A signal from a photosensor 8 for roller pair axes distance detection is processed in accordance with a signal from the photosensor 12 to detect the thickness of a recording member P. In this device, the thickness of the recording member P is detected when the rollers 1, 2 are positioned at the predetermined angle of rotation. Thus, it can be detected accurately without being affected by eccentricities of the rollers 1, 2.

    摘要： A sheet re-feeding path (32) is disposed substantially horizontally at a location below a fixing unit (14) and an image forming unit. At a location below the sheet re-feeding path (32), sheet decks (3, 4) are disposed horizontally along a sheet conveying direction in the sheet re-feeding path (32). Also, a drawing path (37) for switchbacking the sheet is disposed substantially horizontally between the sheet re-feeding path (32) and the sheet decks (3, 4). A sheet feeding path (7) for feeding the sheet from the sheet deck (3) disposed at an upstream side crosses the drawing path (37) to join to the sheet re-feeding path (32). Accordingly, a space, which is occupied by component parts or devices related to the conveyance of the sheet, can be made compact, whereby sheet capacity can be increased.
