ツターの上限位置検出装置。[Claims for Utility Model Registration] 1. An upper limit position detection means for detecting that the shutter curtain has reached the upper limit position and outputting a detection signal thereof, and a position detection switch section for detecting the position of the rising shutter curtain. , and a timer section that starts a timer based on a detection command from the position detection switch section and outputs an upper limit detection signal after a preset timer period elapses. Device. 2. A request for registration of a utility model, characterized in that the position detection switch section has a chattering detection circuit that detects chattering of the switch contacts and outputs a detection command to the timer section at a stable stage when the chatter is no longer present. The upper limit position detection device for an electric shutter according to item 1.
