Abstract
In an endoscope system including an endoscope having an insertion section insertable into a cavity under inspection and an operation section having at least one operation switch, said operation section being connected to a proximal end of said insertion section and a disposable protection cover having an insertion section cover for covering said insertion section of the endoscope and an operation section cover for covering said operation section of the endoscope, said insertion section cover includes a forceps channel through which existing forceps for use in ordinary without-cover endoscopes can be inserted. An inner diameter of the forceps channel is determined to be slightly larger than an outer diameter of most frequently used forceps or standard forceps whose number shows a peak in the outer diameter series of the forceps.
