Endoscope device

Abstract

Abstract PURPOSE:To obtain an optimum observation state without giving pain to a person to be examined by instructing a series of operations in order of water feeding, air feeding, air intake and air feeding to a medium moving mechanism from a control part in response to the one action operation to request washing. CONSTITUTION:A control circuit 13 outputs the control signals to drive solenoid valves 14, 15, 16 and the pumps connected thereto respectively in correspondence thereto to execute a series of the operations in order of water feeding, air feeding, water sucking and air feeding every time when one action operation is carried out by a switch 10 for automatic washing. The automatic washing execution processing is started when the switch 10 for automatic washing is turned on. The solenoid valve 14 for water feeding is then opened to start the water feeding. A timer is simultaneously started. The set time of the timer is the time enough for removing stains, etc. Good photographing environment is obtd. when a series of the consecutive operations of the water feeding, a 1st air feeding and the 2nd air feeding end. A series of the operations to wash the optical members and to relieve the pain of the person to be examined are executed in such a manner simply when the engineer carries out the one action operation.
