Biological information detecting device
Provision of a biological information detecting device capable of stably detecting a biological signal in good condition. A device body, a pair of electrode portions 26 A and 26 B provided in the device body and respectively contacting a biological surface and a band-shaped fixing band 30 for covering the pair of electrode portions 26 A and 26 B and fixing the device body to a body are provided, and a guide portion 40 A which allows relative movement between each of the electrode portions 26 A/ 26 B and the fixing band 30 in an extending direction of the fixing band 30 and restricts movement in a width direction orthogonal to the extending direction is arranged between each of the electrode portions 26 A/ 26 B and the fixing band 30.
1. A biological information detecting device comprising:
a device body;
a pair of electrode portions in the device body and respectively adapted to contact a biological surface;
a band-shaped fixing member that covers the pair of electrode portions and is adapted to fix the device body to the biological surface; and
a guide portion between each of the electrode portions and the fixing member that allows relative movement between each of the electrode portions and the fixing member in an extending direction of the fixing member and restricts movement in a width direction orthogonal to the extending direction,
the guide portion having a base portion attached to the fixing member.
2. The biological information detecting device according to claim 1 , wherein the guide portion includes an engaging portion on a same side as the electrode portions, and an engaged portion extending from the base portion, with which the engaging portion is engaged in the width direction.
3. The biological information detecting device according to claim 2 , wherein a plurality of the engaging portions and engaged portions reside along the width direction.
4. The biological information detecting device according to claim 2 , wherein a length of the engaging portion extending in the extending direction is longer than a length of the engaged portion in the extending direction.
5. The biological information detecting device according to claim 1 , wherein the guide portion includes an engaging portion at a first side of the electrode portion and the fixing member and at a second side of the electrode portion and the fixing member in the width direction.
