Abstract: A probe includes an insertion portion insertable into a body organ, a projecting portion being exposed to an outside of a body after the insertion portion is inserted into the body organ, a device mounting area onto which an external-device coupler is removably mountable, and sensing electrodes provided on the insertion portion and the device mounting area. When the insertion portion is inserted into the body organ, the sensing electrodes detect a biosignal and become conductive with coupling electrodes of the external-device coupler mounted onto the device mounting area. The probe is an electromyograph probe that detects a biosignal measurable by an electromyograph. The insertion portion and the projecting portion of the probe may be integrated or separate from each other. Both of the insertion portion and the projecting portion or only the insertion portion may be disposable.

Abstract: A picture frame device which allows the framing straight members to be removed from the front of the frame device by pivotally rotating the corner joints and has a space formed in a container installed behind the exhibit or the exhibit held between holding sheets, for containing many other exhibitable sheets than the exhibit such as pictures and testimonials.
