1. A lens device, comprising:
a first lens module comprises plurality of lenses;
an image sensor;
a first reflecting module comprising a first reflecting part and a first carrier;
a second reflecting module comprising a second reflecting part and a second carrier;
a rolling unit; and
a first mount;
wherein the first reflecting part and the second reflecting part are configured to form a first light path turning module;
wherein the first light path turning module is configured to transmit a light beam passing through the first lens module to the image sensor by exactly three or four reflections;
wherein the first light path turning module comprises three or four reflecting surfaces on which the reflections occur;
wherein all the reflecting surfaces are plane surfaces;
wherein the first reflecting part is disposed on the first carrier;
wherein the second reflecting part is disposed on the second carrier;
wherein the rolling unit comprises a roller;
wherein either the first carrier or the first mount has a first receiving groove for positioning the roller, the first carrier further has a first guide groove extending in a direction of movement of the first carrier when the first mount has the first receiving groove, or the first mount further has the first guide groove extending in the direction of movement of the first carrier when the first carrier has the first receiving groove;
wherein either the second carrier or the first mount has a second receiving groove for positioning the roller, the second carrier further has a second guide groove extending in a direction of movement of the second carrier and corresponding to the second receiving groove when the first mount has the second receiving groove, or the first mount further has the second guide groove extending in the direction of movement of the second carrier and corresponding to the second receiving groove when the second carrier has the second receiving groove.
