PROBLEM TO BE SOLVED: To reduce a cost of a distance measuring device having a vibration isolation function.SOLUTION: A distance measuring device 1 comprises: a transmission optical system 10 for projecting laser light L1 toward a target object; and a reception optical system 30 for receiving reflected laser light L2 reflected by the target object by a light receiving element 34. When optical axes 2 and 4 are tilted by camera shake or the like, a vibration isolation lens 14 disposed in the transmission optical system 10 is displaced as shown by M1 by a driving mechanism 42, thereby to deflect a beam. A vibration isolation lens 32 disposed in the reception optical system 30 is displaced as shown by M2 by a driving mechanism 43 in linkage with the driving mechanism 42, where the M2 is a motion rougher than the M1. |
