Abstract

PURPOSE:To effectively eliminate network and to improve resolving power by oscillating members which are to be oscillated by 1st and 2nd piezo-electric oscillators in such a manner that the members are oscillate at nearly the same amplitude. CONSTITUTION:Bimorphs 21, 22 are formed of the same specifications and materials of the same specifications are used for mouth pieces 18, 19 in such a manner that the respective equal oscillation moments act on the object side end part and eyepiece side end part of an image guide 11 by these bimorphs 21, 22. The bimorphs 21, 22 are driven by the same driving signal generated by a common pulse generator 25. The object side end part and eyepiece side end part of the image guide 11 can, therefore, be oscillated in the same direction always at the same amplitude and frequency phase. The network is thereby effectively removed and the resolving power is effectively improved; in addition, the bimorphs 21, 22 and the mouth pieces 18, 19 can be made of the same specifications and since just one pulse generator 26 is necessitated, the size is reduced and the simple and inexpensive endoscope device is obtd.
