The present invention provides a banknote scope that is comprised of a lightproof cartridge and a circuit control-detecting device, wherein a light-emitting component of said detecting device is set upon the inside of the lightproof cartridge; said lightproof cartridge has a gap-detecting channel so that the light ray emitted from the detecting device exactly shines on the detecting channel via a detecting window; for observing, the lightproof cartridge has a sight-glass coordinating to the detecting window oppositely. This banknote scope can reduce the radiation of static electric to the human body, and to avoid the user unexpectedly inserting fingers into the detecting window, therefore the operation of it is very safe, and it has a cramped construction, small volume for facilitating carryover and operation.
A banknote scope comprising a lightproof cartridge and a circuit control-detecting device, wherein a light-emitting component of said circuit control-detecting device is positioned within the inside of the lightproof cartridge, said lightproof cartridge having a gap-detecting channel so that a light ray emitted from the circuit control-detecting device exactly shines on the gap-detecting channel via a detecting window, the lightproof cartridge having a sight-glass positioned opposite the detecting window for observation by a user, said lightproof cartridge having a through-hole formed therethrough, a switching button of said circuit control-detecting device projecting through said through-hole, a graded slot being formed within said lightproof cartridge adjacent said through-hole for selectively and releasably maintaining said switching button in a closed state.
