Abstract The present invention is applied to endoscopes for the medical purpose to observe cavities in a body such as a stomach, a duodenum, a bronchus or the like and endoscopes for the industrial purpose to observe the interiors of a machine or component such as an engine. The endoscope according to the invention comprises: an insertable portion to be inserted into a portion to be observed in the cavity of body or the machine or component; a manual control portion connected to the proximal end of the insertable portion and having an ocular portion; and a connecting portion connected at one end thereof to the manual control portion and connected at the other end thereof to an external apparatus having a power source through a connector thereof. In the endoscope of this type, the connector can be removed from the external apparatus and water-tightly connected to the ocular portion. As a result, even if the endoscope is immersed in an antiseptic solution or the like in this state, the endoscope can be immediately used without the ocular portion and the connector being moistened.
An endoscope wherein: said endoscope comprises an insertable portion to be inserted into a portion to be observed, a manual control portion secured thereto with the proximal end of said insertable portion, an ocular portion provided on said manual control portion, and a connecting portion secured at one end thereof to said manual control section and provided at the other end thereof with a connector detachably connected to an external apparatus; and said connector, when detached from said external apparatus, is water-tightly connectible to said ocular portion.
