Abstract:
1. A sheet thickness detection apparatus for detecting a thickness of plural paper sheets on a sheet placement platform, said sheet thickness detection apparatus having a maximum allowable thickness, said sheet thickness detection apparatus comprising: a bracket comprising a base with a perforation; a power device fixed on a first surface of said base; a first linking lever connected with said power device and driven by said power device to be moved, wherein said first linking lever has a notch; a second linking lever having a first end and a second end, wherein as said first linking lever is moved, said second linking lever is correspondingly swung, wherein said first end of said second linking lever is pivotally coupled with said first linking lever; a sheet pressing part extended from said second end of said second linking lever and simultaneously swung with said second linking lever; and a sensing device comprising a supporting part and a sensor, wherein said supporting part is connected to a second surface of said base, wherein said sensor is fixed on said supporting part and penetrated through said perforation from said second surface of said base, so that said sensor is exposed to a lateral side of said first linking lever to detect whether said thickness of said plural paper sheets exceeds said maximum allowable thickness or not, wherein said supporting part comprises three hooks, and said base further comprises three sliding grooves, wherein when said supporting part is connected with said base, said three hooks are respectively embedded into said three sliding grooves, so that said supporting part is only permitted to be moved in a direction parallel with said first linking lever, wherein by moving said supporting part, said sensor is moved to a position where said maximum allowable thickness is detectable.
