Abstract
A moving device including a driven conveyor, a control device for controlling the speed of the conveyor and a start-up sensor, which monitors a monitoring region in front of the moving device and outputs a start-up signal to the control device upon detecting an object, wherein, upon a provided start-up signal, the control device sets into motion or accelerates the moving device. The start-up sensor is a TOF sensor having (i) a light source for emitting modulated light, (ii) at least one receiving sensor for receiving light from the light source that is reflected at the object, and (iii) an evaluation electronic system configured for detecting, from the comparison of emitted and received light, the distance of the object from the TOF sensor and the position of the object in the space in front of the moving device.
