Conventionally, in this kind of invention, for example, as disclosed in Patent Document 1, the door (door sheet 30) is opened and closed at the lower end side of an opening / closing body (opening / closing body main body 10) made of a flexible sheet material. Even when the opening / closing body (opening / closing body main body 10) is closed, the door (door sheet 30) is opened and the passage opening ( There is a so-called screen shutter device that allows passage through the opening 11).
In such a conventional screen shutter device, since the opening / closing body is made of a flexible sheet material that is relatively light and flexible, the opening / closing body during the closing operation should contact the object on the lower side. Even if it comes into contact, the impact on the abutted object can be relatively small.
However, in recent years, it has been demanded to improve the safety of the conventional screen shutter device. Particularly, in an opening / closing device having a relatively long width in the width direction of the opening / closing body, the weight of the entire opening / closing body is increased, and the impact upon contact with an object is increased. preferable.

Therefore, it is proposed to provide an obstacle sensing device described in Patent Document 2, for example, at the end of the opening and closing body of the conventional screen shutter device in the closing direction.
In the switchgear provided with the obstacle sensing device as described above, a mode in which a sensing signal from the obstacle sensing device is wirelessly transmitted to the control unit and a mode in which cable transmission is performed can be considered.
In the former mode, there is a risk of malfunction due to, for example, smoke when the infrared system is used, and there is a risk of adverse effects such as noise when the radio system is used.
Therefore, it is preferable to use a mode in which the sensing signal is transmitted by wire as in the latter case. However, in this case, the code is not disturbed when a passing person or an object passes through the passage port. Cost.
