PROBLEM TO BE SOLVED: To provide a measuring device that can measure both the distance between the device and a measurement target object and the velocity of the measurement target object.SOLUTION: A distance velocity measuring device (1) comprises: a laser light source part (end surface light emission laser light source 11 and light receiving element 12) that emits a laser beam to a measurement target object (print sheet 50); and a light path adjustment part (liquid crystal shutter 10) that adjusts a light path of the laser beam; the light path adjustment part (liquid crystal shutter 10) includes a transmission area (10a) through which the laser beam transmits.SELECTED DRAWING: Figure 2 |
