Sheet-type medium deviation correction device and automatic teller machine

Abstract

A sheet-type medium deviation correction device comprises an upper holding plate, a lower holding plate, a front guide wheel set, a front end position detecting element, a lateral border position detecting unit, a deviation correction assembly, and a delivery assembly. The deviation correction assembly comprises a belt and a pair of belt pulleys. The delivery direction of the belt is perpendicular to the lateral border of the upper holding plate or the lower holding plate. The delivery assembly comprises a pair of delivery wheels. The delivery direction of the delivery wheels is perpendicular to that of the belt. The belt is used for delivering a sheet-type medium to the border of the belt to be aligned with the lateral border of the holding plate, thereby achieving the deviation correction purpose.

1 . A skew-correction device for sheet-type mediums, comprising:
 an upper holding plate and a lower holding plate for holding the following parts and forming a conveying passage for the sheet-type mediums,   a front guide wheel set, at least comprising one front guide wheel, wherein the one front guide wheel is mounted at a front end of the upper holding plate or a front end of the lower holding plate for guiding the mediums into the conveying passage,   a front end position detecting element disposed at the front end of each of the upper holding plate and the lower holding plate for detecting whether a medium has entered into the conveying passage or not,   a side edge position detecting unit, comprising at least two position detectors, wherein the at least two position detectors are distributed at a certain interval side edges of the upper holding plate and the lower holding plate, and the at least two position detectors are arranged in a direction parallel to the side edges, the at least two position detectors are configured to detect whether an edge of the medium is aligned with the side edge of the upper holding plate or the side edge of the lower holding plate,   at least one skew-correction assembly, comprising a belt and a pair of pulleys, wherein a conveying direction of the belt is perpendicular to the side edge of the upper holding plate or the side edge of the lower holding plate, and   at least one conveying assembly, comprising a pair of conveying wheels, wherein a conveying direction of the conveying wheels is perpendicular to the conveying direction of the belt.   
     
     
         2 . The skew-correction device for sheet-type mediums according to  claim 1 , wherein the skew-correction assembly is located between the conveying assembly and the front guide wheel set. 
     
     
         3 . The skew-correction device for sheet-type mediums according to  claim 2 , wherein two sets of skew-correction assemblies are provided, and two sets of conveying assemblies are provided, wherein one set of skew-correction assembly is located between one set of conveying assembly and the front guide wheel set, and the other skew-correction assembly is located between the two sets of conveying assemblies. 
     
     
         4 . The skew-correction device for sheet-type mediums according to  claim 3 , wherein the pulley of the skew-correction assembly is a drum-shaped wheel, and the drum-shaped wheel is fixed to the upper holding plate and/or the lower holding plate by a shaft. 
     
     
         5 . An automatic teller machine, comprising a skew-correction device for sheet-type mediums, wherein the skew-correction device for sheet-type mediums is the skew-correction device for sheet-type mediums according to  claim 1 . 
     
     
         6 . An automatic teller machine, comprising a skew-correction device for sheet-type mediums, wherein the skew-correction device for sheet-type mediums is the skew-correction device for sheet-type mediums according to  claim 2 . 
     
     
         7 . An automatic teller machine, comprising a skew-correction device for sheet-type mediums, wherein the skew-correction device for sheet-type mediums is the skew-correction device for sheet-type mediums according to  claim 3 . 
     
     
         8 . An automatic teller machine, comprising a skew-correction device for sheet-type mediums, wherein the skew-correction device for sheet-type mediums is the skew-correction device for sheet-type mediums according to  claim 4 .
