A kind of camera lens forward direction indicating arrangement of introscope,Mainly include: a pick-up lens group,To pick-up image； One can be formed flexible pipe,The fixed pick-up lens group in front end； One hard tube,The Hou end of the fixed flexible pipe that can be formed in front end； And a handle,The Hou end of the fixed hard tube in front end； Wherein,The pick-up lens group,The flexible pipe that can be formed,When the hard tube and the handle what rotate,Rotation angle be it is consistent,The what pick-up lens group,The flexible pipe that can be formed,At least one is provided with a labelling piece for the hard tube or handle,When the hard tube level is put,The labelling piece position what pick-up lens group,The flexible pipe that can be formed,The hard tube or at least one of top of the handle,Above the image of the corresponding pick-up lens group photography. Thereby, when the labelling piece position what pick-up lens group, the flexible pipe that can be formed, the hard tube or at least one of top of the handle, above the image for then corresponding to the pick-up lens group photography, that is, the pick-up lens group is positive photography, up to the effect of just what operation.一種內視鏡之鏡頭正向標示結構，主要包含有：一攝像鏡頭組，用以擷取影像；一可定型撓性管，前端固設該攝像鏡頭組；一硬管，前端固設該可定型撓性管之後端；以及一握把，前端固設該硬管之後端；其中，該攝像鏡頭組、該可定型撓性管、該硬管及該握把於轉動時，旋轉角度為一致，於該攝像鏡頭組、該可定型撓性管、該硬管或握把至少其中之一設置有一標示件，該硬管水平置放時，該標示件位於該攝像鏡頭組、該可定型撓性管、該硬管或是該握把至少其中之一的上方，對應該攝像鏡頭組攝影之影像上方。藉此，當該標示件位於該攝像鏡頭組、該可定型撓性管、該硬管或是該握把至少其中之一的上方，則對應該攝像鏡頭組攝影之影像上方，亦即該攝像鏡頭組為正向攝影，以達便於操作之之功效。
