Title:
ENDOSCOPE DEVICE
Document Type and Number:
Japanese Patent JP3811289
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To simply and quickly execute an endoscopic inspection by easily executing the initialization of an endoscope device.
SOLUTION: A zoom lens 38 built in an objective lens system 34 arranged on the tip part 13 of an endoscope 2 is connected to an actuator 39 and allowed to be moved in an optical axis direction together with the movement of the actuator 39, based on a drive signal outputted from a driving part 41 built in a zoom controller 6. When a power supply switch 46 is turned on, a moving instruction signal is inputted to a CPU constituting a control circuit 43 simultaneously with the ON operation, the CPU reads out the waveform data of a signal for moving the actuator 9 to a wide angle side, executes the D/A conversion or the like of the signal and outputs the analog signal from the driving part 41 and the zoom lens 38 is automatically moved up to the widest angle end to be a prescribed position required for the initialization of a normal endoscopic inspection.
