Digital camera module with manual focusing function

A digital camera, comprising:

• a base having an elastic element mounted on an inner wall thereof, the base including a base seat, and a sleeve mounted to the base seat, the barrel being received in the sleeve, the elastic element being disposed in the sleeve;
• a barrel having an outer wall defining more than one aperture, the elastic element engaging into one of the apertures when the barrel being movably received in the base;
• at least one rod being connected with the barrel and the base so that when the barrel rotated relative to the base, the barrel caused to slide axially relative to the base;
• and
• an image sensor fixed with the base.

A camera module comprising:

• a base having a cavity defined therein, the cavity having an inner base wall;
• an image sensor disposed in cavity;
• a barrel having an outside barrel wall facing the inner base wall, and including at least one lens fixed therein, the lens aligning with the image sensor;
• an outer surface of the barrel and the inner base wall in the cavity are frictional surfaces;
• a plurality of apertures defined in one of the inner base wall and the outer barrel wall;
• an elastic element is formed on the other of the inner base wall and the outer barrel wall;
• and
• a connecting member having a first connecting end and a second connecting end, wherein the first connecting end is connected with the barrel, and the second connecting end is fixed relative to the base;
• wherein when force is applied, the barrel is able to rotate relative to the base, and when the force is stopped, the barrel is able to be kept in position owing to the friction between the frictional surfaces;
• the elastic element selectively in the apertures for circumferentially positioning the barrel with respect to the base, and the barrel is caused to slide axially relative to the base by the connecting member.
