Shelf imaging device for a shelf support and shelf system comprising the shelf imaging device

A shelf imaging device for a shelf support, wherein the shelf support is installed on a shelf edge and comprises a receiving section configured to receive electronic shelf labels, the receiving section comprising two facing wings extending in a longitudinal direction, one of the two wings has in its medial region a longitudinal groove, the groove has a plurality of holes, wherein the shelf imaging device comprises:

• a back side configured to be removably fitted in the receiving section,
• a front side opposite to the back side,
• an optical sensor configured to acquire an image of shelves facing the front side,
• an engaging member for engaging the receiving section so as to lock the shelf imaging device into the shelf support, when the engaging member protrudes from the shelf imaging device and engages one of the holes, at or behind the back side of the shelf imaging device,
• a guiding element and a spring, the guiding element and the spring being configured together to urge upwardly the engaging member to project through an opening of the shelf imaging device,
• an actuator configured to move the engaging member between a locking position where the shelf imaging device is locked into the shelf support and a free position where the shelf imaging device is free to be displaced relative to the shelf support, the actuator comprising a magnetic element which extends between a front end located near the front side or near a lateral side of the shelf imaging device, and a back end linked to the engaging member, and
• a link linking together the guiding element, the engaging member and the actuator.
