A compensating mechanism includes a base unit, a transmission unit, an adjusting cap and a rotation setting unit. The base unit includes a grooved portion that includes a first groove and a second groove communicated with the first groove. The second groove includes a first end and a second end opposite to the first end. The first end is connected to the first groove. The first end and the second end have a height difference therebetween in an axial direction of the base unit. The transmission unit is disposed on the base unit. The adjusting cap is connected to the transmission unit. The adjusting cap drives the transmission unit to rotate when the adjusting cap is rotated. The rotation setting unit includes a movable element that is movably disposed on the transmission unit to be connected to the grooved element or to be separated from the grooved element.

A multi-group lens assembly (10), a camera module (100), and an electronic device (200) therefore are provided. The multi-group lens assembly (10) includes at least two group units (11 and 12). At least a first gap (15) is provided between the at least two adjacent group units (11 and 12) to compensate a difference between the multi-group lens assembly (10) and an optical design system, thus allowing an optical system of the multi-group lens assembly conform to the optical design system of the present invention.

An optical information reader includes an imaging lens and a lens retainer retaining the imaging lens and assembled, in this state, into the holder. The lens retainer includes a flange bottom surface and end faces as a reference surface that is parallel to an optical axis of the imaging lens. The holder includes a top surface and edge faces as a guide surface. The guide surface is brought into surface contact with the flange bottom surface and the end faces when the lens retainer is assembled into the holder, and is brought into slidable contact with the flange bottom surface and the end faces when the lens retainer is moved along the optical axis. Thus, influence of one-sided blur is minimized in terms of variation in resolution which is measured when obtaining an optimal focus position by changing relative positions of the area sensor and the imaging lens.
