Abstract

An endoscope includes an insert portion, a display portion, a manipulation portion, a casing which houses the display portion and the manipulation portion at a front side, and to which the insert portion is connected at a back side, and a battery. The casing has an upper portion in which the display portion is housed and a lower portion in which the manipulation portion is housed. The insert portion is connected to the lower portion and extends from the lower portion in a first direction. And a line connecting a center of gravity of the battery and a center of gravity of the casing while the battery is housed in the casing extends in a second direction that intersects the first direction at an angle.

Claims

1. An endoscope comprising:

a long flexible insert portion which has an imaging device on a tip thereof;

a display portion which displays an image obtained by the imaging device;

a manipulation portion for bending the insert portion;

a casing which houses the display portion and the manipulation portion at a front side, and to which the insert portion is connected at a back side; and

a battery which supplies electricity to the display portion,

wherein the casing has an upper portion in which the display portion is housed and a lower portion in which the manipulation portion is housed,

wherein the insert portion is connected to the lower portion, is coaxial with the manipulation portion, and extends from the lower portion in a first direction, and

wherein a line connecting a center of gravity of the battery and a center of gravity of the casing while the battery is housed in the casing extends in a second direction that intersects the first direction at a position inside the lower portion.
