Abstract
Abstract An apparatus for inspecting whether an object is good or bad includes a video camera picking up an object to be inspected a stroboscope radiating the object, a detector for detecting a predetermined inspection position of the object and producing a position signal when the object arrives at the predetermined inspection position, a circuit for receiving the position signal from the position detector and producing a signal to flash the stroboscope, a circuit for receiving an output from the video camera and for inspecting whether the object is good or bad, a separator for separating a synchronizing signal from a composite video signal from the video camera, and a circuit for making the electron beam of the video camera OFF at latest before receiving the position signal from the position detector and making the electron beam ON and starting the inspecting operation of the inspecting circuit when receiving the synchronizing signal.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
166 words
An apparatus for inspecting whether an object is good or bad comprising: (a) a video camera for picking up an object to be inspected; (b) a stroboscope for radiating said object; (c) detecting means for detecting a predetermined inspection position of said object and producing a position signal when said object arrives at said predetermined inspection position; (d) means for receiving the position signal from said position detecting means and for producing a signal to flash said stroboscope; (e) means for receiving an output from said video camera and for inspecting whether said object is good or bad; (f) means for separating a synchronizing signal from a composite video signal derived from said video camera; and (g) means for making the electron beam of said video camera OFF at the latest before receiving the position signal from said position detecting means and then making the electron beam ON when receiving the synchronizing signal after said position signal and starting the inspecting operation of said inspecting means.
Claim 2
Independent Claim
166 words
An apparatus for inspecting whether an object is good or bad comprising: (a) a video camera for picking up an object to be inspected; (b) a stroboscope for radiating said object; (c) detecting means for detecting a predetermined inspection position of said object and producing a position signal when said object arrives at said predetermined inspection position; (d) means for receiving the position signal from said position detecting means and for producing a signal to flash said stroboscope; (e) means for receiving an output from said video camera and for inspecting whether said object is good or bad; (f) means for separating a synchronizing signal from a composite video signal derived from said video camera; and (g) means for making the electron beam of said video camera OFF at the latest before receiving the position signal from said position detecting means and then making the electron beam ON when receiving the synchronizing signal after said position signal and starting the inspecting operation of said inspecting means.
Claim 3
Dependent Claim
61 words
An apparatus as claimed in claim 1, wherein said last-mentioned means includes a first signal generating means which produces a signal to make the electron beam of said video camera OFF and ON and a second signal generating means which produces a signal to start the inspection operation of said inspecting means in synchronism with the ON of said video camera.
Claim 4
Dependent Claim
25 words
An apparatus as claimed in claim 1, wherein said separating means separates the vertical synchronizing signal from the composite video signal of said video camera.
Claim 5
Independent Claim
181 words
An apparatus for inspecting whether an object is good or bad comprising: (a) a video camera for picking up an object to be inspected; (b) a stroboscope for radiating said object; (c) detecting means for detecting a predetermined inspection position of said object and producing a position signal when said object arrives at said predetermined inspection position; (d) means for receiving the position signal from said position detecting means and for producing a signal to flash said stroboscope; (e) means for receiving an output from said video camera and for inspecting whether said object is good or bad; (f) means for separating a synchronizing signal from a composite video signal from said video camera; (g) means for making the electron beam of said video camera OFF at the latest before receiving the position signal from said position detecting means and making the electron beam ON when receiving the synchronizing signal from said synchronizing signal separating means after said position signal; and (h) means for producing a signal to start the inspection operation of said inspecting means when receiving the synchronizing signal.
Claim 6
Independent Claim
181 words
An apparatus for inspecting whether an object is good or bad comprising: (a) a video camera for picking up an object to be inspected; (b) a stroboscope for radiating said object; (c) detecting means for detecting a predetermined inspection position of said object and producing a position signal when said object arrives at said predetermined inspection position; (d) means for receiving the position signal from said position detecting means and for producing a signal to flash said stroboscope; (e) means for receiving an output from said video camera and for inspecting whether said object is good or bad; (f) means for separating a synchronizing signal from a composite video signal from said video camera; (g) means for making the electron beam of said video camera OFF at the latest before receiving the position signal from said position detecting means and making the electron beam ON when receiving the synchronizing signal from said synchronizing signal separating means after said position signal; and (h) means for producing a signal to start the inspection operation of said inspecting means when receiving the synchronizing signal.
