Abstract

A thermal imaging camera, with an electromechanical shutter device for interrupting the ray path from time to time, has a motor (1), a motor shaft (2) and a shutter flag (3). The motor shaft (2) and the shutter flag (3) are in connection with one another via a crank-and-rocker mechanism. The crank-and-rocker mechanism includes a crank (4) rotatable about the motor shaft (2) with a crank pin (5) and with a rocker (6), at one end of which an elongated hole (8) is provided, which forms a rectilinear sliding joint together with the crank pin (5), and at the other end of which the shutter flag (3) is formed.
