An electrical information device and a medicament delivery device are presented. The electrical information device includes at least one start of delivery sensor configured to detect a distal axial movement of a release member of the medicament delivery device. The release member is configured to be distally moved when an activator member of the medicament delivery device 1 is forced distally. The electrical information device also includes at least one information communication unit, which is configured to communicate information related to the medicament delivery. The electrical information device further includes at least one activation unit, which is configured to activate the at least one information communication unit based on a detected distal axial movement of the release member.電資訊裝置及藥物輸送裝置被呈現。該電資訊裝置包括輸送感測器之至少一起點，被建構用於偵測該藥物輸送裝置的釋放構件之遠側軸向運動。當該藥物輸送裝置(1)的啟動器構件經強迫朝遠側時，該釋放構件被建構用於待朝遠側運動。該電資訊裝置亦包括至少一資訊傳送單元，被建構用於傳送關於該藥物輸送之資訊。該電資訊裝置另包括至少一啟動單元，其被建構用以基於該釋放構件的經偵測之遠側軸向運動來啟動該至少一資訊傳送單元。
