Abstract:
1. An endoscope apparatus comprising: an optical adapter including a first resistance and a switch element which are connected in parallel to each other; an endoscope comprising a distal end portion to which the optical adapter is detachably mountable; a second resistance which is arranged to be connected in series to the first resistance when the optical adapter is mounted to the distal end portion of the endoscope; a DC power supply which is connected in series to the second resistance; and a control section which calculates a value of the first resistance based on (i) a first divided voltage value at a connection point between the first resistance and the second resistance at a time when the switch element is closed, (ii) a second divided voltage value at the connection point at a time when the switch element is opened, and (iii) a value of the second resistance, wherein the control section discriminates a kind of the optical adapter based on the calculated value of the first resistance.
