Abstract
A push switch device of an endoscope includes an electric operation switch and a switch button that pushes the operation switch. The switch button includes: a shaft inserted through a hole of a case body of an operation portion; a button top arranged outside the case body and configured to receive an operational force orthogonal to the shaft; a spherical-shaped pusher configured to push in the operation switch by receiving the operational force; and a flange having an arc and provided at midway of the shaft, the flange being configured such that a part thereof abuts against an inside of the operation portion when the shaft is tilted by the operational force.
Claims20
A push switch device of an endoscope, which is provided at an operation portion configured to be grasped by an operator, the push switch device comprising:
- an operation switch configured to make an electric circuit conductive;
- and
- a switch button configured to push the operation switch,
- wherein
- the switch button comprises:
- a shaft arranged by being inserted through a hole formed in a case body of the operation portion;
- a button top connected to one end of the shaft and arranged outside the case body, the button top being configured to receive an operational force in a direction orthogonal to the shaft;
- a pusher having a shape including at least a part of a spherical body having an outer diameter larger than an outer diameter of the shaft, the pusher being configured to move when the button top receives the operational force, to push in the operation switch arranged facing the pusher;
- and
- a flange provided at midway of the shaft and including an arc which is on an outer surface of the flange and has a diameter larger than an outer diameter of the button top, the flange being housed in an inside of the operation portion and configured such that a part of the outer surface is brought into a state abuttable against the inside of the operation portion when the shaft is tilted by the operational force applied to the button top.
