An endoscope comprising a light source, an insertion portion that is inserted into the space to be inspected and emits light from the light source from a light emitting portion at the tip, and a tip optical adapter that is detachably attached to the tip portion of the insertion portion A device,
Adapter detecting means for detecting attachment and detachment of the tip optical adapter to and from the insertion portion, and emission light control means for controlling light emitted from the emission portion in conjunction with detection by the adapter detection means. Endoscopic device characterized. The endoscope apparatus according to claim 1, wherein the adapter detection unit is a switch that is provided at a distal end portion of the insertion portion and that is turned on and off depending on whether or not the distal optical adapter is attached. The adapter detection means is provided in a pair of electrodes spaced apart at the distal end portion of the insertion portion and the distal end optical adapter, and the distal end optical adapter is mounted in a predetermined position of the insertion portion. The endoscope apparatus according to claim 1, further comprising a connection unit that connects and connects the pair of electrodes. The outgoing light control unit receives the detection signal in the state where the tip optical adapter from the adapter detection known means has been removed, consists of a power supply control means for decreasing the output power supply to the light source block or to the threshold, The endoscope apparatus according to any one of claims 1 to 5, wherein The endoscope according to claim 2 or 3, wherein the emitted light control means is power supply means for directly turning on and off the power supply of the light source in conjunction with detection by the adapter detection means. apparatus. 6. The output light control means according to claim 1, further comprising an optical path control means for receiving a detection signal from the adapter detection means and blocking or dimming the optical path of the light. Endoscopic device. The optical path control means is provided on an optical path between an exit end face of the light source and an entrance end face of a light guide member that guides light from the exit end face to a distal end portion of the insertion portion. The endoscope apparatus according to Item 8. 2. The tip optical adapter is characterized in that the light source is a laser diode that emits laser light of a specific wavelength, and optical property conversion means for converting the laser light into light of different optical properties is provided in the tip optical adapter. The endoscope apparatus according to any one of 9. The endoscope apparatus according to claim 10, wherein the optical characteristic conversion unit is a phosphor that emits light of different wavelengths using the laser light as excitation light. The endoscope apparatus according to claim 11, wherein the distal optical adapter provided with the phosphor is attached to a distal end of the insertion portion to irradiate white light. The endoscope apparatus according to claim 10, wherein the optical characteristic conversion unit is a diffusion optical member that diffuses and irradiates the laser light.
