A displacement detection device which detects the displacement of a paper sheet in transit in a paper sheet sorter that picks up and transports the paper sheet such as the bank-notes. The displacement detection device includes photo sensors which detect the leading edge of the paper sheet that is being transported, and a photo position detector which detects the distance from the conveyer belt to the side edge of said paper sheet. Each of said photo sensors comprises of a light emitter and a light receiver which are arranged on opposite sides of the paper sheet. The photo position detector is placed on the downstream side in the conveyance direction of the photo sensors, extending perpendicularly to the conveyance line, and comprises a light projector and a light receiver with linear form and equal length arranged symmetrically with respect to the paper sheet. Signals from the photo sensors and photo position detector are processed by a microcomputer to determine the passing interval, the inclination, and the lateral shift of the paper sheet.

Method of and device for detecting displacement of paper sheets

Paper leaves, conveyed through a conveyer belt system, are inserted into arcuate grooves of rotating conveying wheels and subjected to a running speed reduction, and discharged under the rotating conveying wheels into a space by the use of a stopper. When the number of paper leaves falling into the space reaches a preset count, for example, projecting devices are actuated to project bar elements into the space, with paper leaves exceeding the preset count being piled on the bar elements. The preset number of paper leaves are then transferred from the space. Once transfer is complete, the bar elements are retracted enabling the paper leaves collected thereupon to fall into the space.

Sheet handling device

A printing head for a wire dot printer having printing wires each of which is attached to an armature, wire driving mechanisms for reciprocating the printing wires in a first direction, each having the armature moved in the first direction, a magnetic frame including an air gap in which the armature is received swingably in the first direction, a magnetizing coil for generating a magnetic flux in the air gap, a sliding portion formed in the magnetic frame for adjusting the length of the air gap, and an armature support member attached to the magnetic frame to resiliently support the armature, the armature support member being slidable not only in the first direction but also in a second direction which is perpendicular to the first direction so that the free position of the armature may be adjustable independently of the adjustment of the length of the air gap.
