Distance-adjustable counting device and induction type automatic distance-adjustable counting device

A distance-adjustable counting device and an induction type automatic distance-adjustable counting device are disclosed, adapted to be coupled to a container having an opening and in which at least a to-be-detected object is accommodated, for solving the problem that the shooting range of the existing counting device can not be adjusted according to the height of a container. The counting device includes a main body having a detecting surface facing toward the opening. A camera unit is disposed on the detecting surface. A supporting unit or a telescopic supporting unit is disposed between the main body and the container, for adjusting the distance between the main body and the container to a standard distance. A processor is signally connected and thereby controls the camera unit to capture the to-be-detected object and recognize a quantity information of the to-be-detected object. After that, the quantity information is output by an electronic device. According to the present disclosure, no matter whether th
