Claims

[Claims for Utility Model Registration] A shutter main body, a shutter elevating means for lifting or lowering the shutter main body by winding it up or unwinding it, and a shutter storage section for storing the shutter main body rolled up by the shutter elevating means. The shutter main body includes a sheet-like member and a lower edge member attached to the lower edge of the sheet-like member, an upper pressure sensor is attached to the upper surface of the lower edge member, and an upper pressure sensor is attached to the upper surface of the lower edge member. A lower pressure sensor is attached to the lower surface of the shutter lifting means, and the shutter elevating means has a driving means and a control means for controlling the operation of the driving means, and the control means sends a rise signal and a fall signal to the drive means. 1. A shutter comprising: a switch section for transmitting a signal; and an interlock means for blocking a rising signal using the output of the upper pressure sensor and blocking a descending signal using the output of the lower pressure sensor.
