Banknote validation device and processing inspection apparatus

A banknote validation device, comprising:

• a light source array, which comprises a number of light emission units arranged in at least one row;
• at least one light receiver, which is operable to receive light emitting from the light emission units and to generate, upon receiving the light emitting from the light emission units, a detection signal corresponding thereto;
• a banknote channel, which is arranged between the light source array and the light receiver, the banknote channel being adapted to receive a banknote to be validated to pass therethrough, the at least one light receiver being arranged to correspond to multiple light emission units of the light source array, such that when no banknote is present in the banknote channel, the light emitting from the light emission units toward the banknote channel is all receivable by the light receiver corresponding thereto;
• and when the banknote to be validated is passing through the banknote channel and blocks the light emitting from at least a portion of the light emission units, the light emitting from the light emission units that are blocked toward the banknote channel is unreceivable by the corresponding light receiver;
• and
• a control circuit, which is electrically connected to the light source array and the light receiver, the control circuit being operable to control the light emission units of the light source array to sequentially emit light according to a preset timing sequence of lighting, the control circuit being operable to implement inspection of the banknote passing through the banknote channel according to the detection signal generated by the light receiver.
