WIPO Patent Application WO/2021/230341
Kind Code:
A1
Abstract:
[Problem] To provide a pencil sharpener that reliably issues a notification regarding the completion of cutting. [Solution] This pencil sharpener 1 comprises: a pencil support member 3 that supports a pencil 4; a cutter unit 7 that rotates around the axis of the pencil 4 supported by the pencil support member 3 and cuts the tip end of the pencil 4; an intermediate member 74 that is movable forward and backward at the tip end of the pencil 4, is disposed so as to be rotatable around the same axis as the cutter unit 7, and has a notification starting part (bias projection 745); and a cutting completion notification means (sound production member 8) that is provided so as to be able to be pressed and moved by the notification starting part. Furthermore, as the intermediate member 74 is moved forward by being biased by the tip end of the pencil 4 of which cutting has progressed, the notification starting part presses the cutting completion notification means and causes the cutting completion notification means to continuously issue a cutting completion notification for the pencil 4.
