An electrical connector having an electrical plug (102) to be plugged into an electrical receptacle (130). The electrical plug (102) includes an electrically insulative plate-like substrate and a plurality of first electrical contacts (118) formed in parallel on at least a side surface at one end of the substrate for a predetermined length from the one end. The plug further includes a shielding part (126) formed of an electrical conductor which substantially shields all of the substrate in a position nearer an end other than the one end having the electrical contacts (118). The electrical receptacle includes an electrically insulative receiving member (138) forming at least part of a recess in which the substrate of the plug is inserted. A plurality of second electrical contacts (142) are arranged in the receiving member (138) so as to contact the plurality of contacts in the plug whenever the substrate of the plug is inserted into the recess. The electrical receptacle (130) also includes a shielding electrical contact (140) formed to contact the shielding part of the electrical plug (102). The shielding electrical contact includes a liquid removing member (235) for removing liquid from the substrate during insertion into the recess. A heated air mechanism (271, 273) may be included to assist in liquid removal. The shielding may also serve the purpose of latching the plug and receptacle together and the plug may be of circular shape.

An endoscope apparatus comprising an electrical connector which is electrically connected to an electrical device such as a CCD in an organism inserting device such as an endoscope which has an inserting section inserted into a organism. The electrical connector is connected to an electrical connector receptacle such as a control unit after the organism inserting device has been disinfected and sterilized by disinfection liquid. Processing is first performed in which the liquid remaining in the vicinity of an electrical contact of the electrical connector is removed by a liquid removing mechanism and, thereafter, electrical operation occurs. Thus, generation of a short-circuiting accident is prevented.

Endoscope apparatus provided with liquid removing mechanism for the

An object is illuminated sequentially with light of wavelengths in respective narrow bands through a light guide in an electronic endoscope provided with an imaging device. The picture images are photoelectrically converted by the imaging device and are temporarily stored respectively in memories. The spectral distribution characteristics of the object are calculated by using spectral distribution calculating data and are displayed on a display.
