摘要： An apparatus for measuring a property of a traveling sheet (10) comprises a sensor body (16, 30, 64) and a target body (14, 20) adapted to be located on opposite sides of the sheet and constrained (e.g., by gas bearings formed between 32 and 36 and 38) during the measurement without substantial solid bodily contact for movement along respective portions of a mutual sensor path intersecting the path of the sheet. Means (44, 46, 48, 56, 64, 70, 72, 74, 76) effective without substantial solid bodily contact normally maintain each of the sensor and target bodies at respective, substantially constant distances from the opposite, nominal surfaces of the sheet while permitting the movement of the bodies along the sensor path in response to the position and thickness of the sheet between the nominal surfaces. Sheet property sensing means, including means (18, 84, 94, 118) aboard the sensor body and means (20) aboard the target body interact through the sheet to produce aboard the sensor body a response dependent on the sheet property and produce, without solid bodily connections, manifestations of the sheet property dependent response at a location (at 96) spaced from the sensor body. Means (24, 96) I including means (96) at the spaced location detect the manifestations and produce (at 26) a sheet property-indicative response.

摘要： A device for detecting the thickness of paper sheet (P) such as bank note used for a paper transfer system comprises a thickness detection roll (12) rotatably supported at a free end of a pivotal lever (13) and urged against a paper sheettransfer roll (10), via a paper sheet when the paper sheet is transferred therebetween. The pivotal lever is pivotally supported by a lever mounting unit (21), which is detachably mounted on a frame (15) of the transfer system. The lever mounting unit is positioned in a predetermined mounting position by positioning pins (24) and locked at that position by a fixing means (25) including a toggle mechanism. With a change of the thickness of paper sheet being transferred the gap between an electromagnetic sensor (14) mounted in the frame and a corresponding sensing surface (13a) of the lever (13) is changed, and thereby the paper sheet thickness is electromagnetically detected.
