A foldable desktop electronic magnifier, comprising: a support plate entirely supporting the magnifier; a horizontal link arm secured to the support plate; a first vertical link arm rotatably coupled to the first horizontal link arm; a camera supporting part rotatably coupled to the first vertical link arm and having a camera mounted therein; a second vertical link arm rotatably coupled to the first vertical link arm; and a monitor rotatably secured to the second vertical link arm, wherein the first vertical link arm is rotated with respect to the first horizontal link arm, the second vertical link arm is rotated with respect to the first vertical link arm, and the monitor is rotated with respect to the second vertical link arm, whereby the monitor is folded in contact with the support plate, the camera supporting part including: a securing body secured to a first side of the first vertical link arm; a body cap coupled to the securing body; a cam spring secured to the body cap; a cam lever provided at an outside of the body cap; a camera casing having the camera mounted therein in a secured manner; a rotary bracket inserted into the camera casing and being rotatable in cooperation with operation of the cam lever; and a cam lever shaft having a semicircular cross section and passing through an insertion hole of the cam lever, an insertion hole of the body cap, the cam spring, and an insertion hole of the securing body, whereby a tip of the cam lever shaft is inserted into an insertion hole of the rotary bracket, the insertion hole of the cam lever having a semicircular cross section so as to correspond to a shape of the cam lever shaft, the cam lever shaft being rotated in cooperation with rotation of the cam lever, characterised in that the cam lever shaft is inserted into the cam spring, and the cam spring has two horizontal lines parallel to each other, the cam spring elastically supporting rotation of the cam lever shaft such that rotation of the cam lever shaft is stopped at a predetermined angle of rotation. a support plate entirely supporting the magnifier;
