发明名称 Pull string mechanism in a pull string type sound reproducing device
摘要 A pull string mechanism for a pull string type sound reproducing device utilizes a string supporting member which is resiliently movable only in an upward and downward direction. The string supporting member is disposed adjacent a pull out hole, such that the path of the pull string from the pull out hole, via the string supporting means and a bobbin for taking up and paying off the pull-string can follow a crank shaped path with the angle of turning being not larger than a right angle.
