Filed: 2002-06-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a hammer leaving a proof indicating the strike at the place that is hammered.  <P>SOLUTION: When a user strikes an object with the hammer 1, the tip of a core member 70 projected onto a striking face 3a first abuts on the object, and a colorant is attached on the object. The tip of the core member 70 is then pressed to the object. The core member 70 is slid in a slide hole 30 against the biasing force of a biasing tool 72. The tip of the core member 70 sinks under the striking face 3a, and the object is struck with the striking face 3a. When the striking face 3a is separated from the object, the core member 70 is slid in the slide hole30, and the tip is projected above the striking face 3a. Because a marking tool 7 attaches the colorant on the struck point when the object is struck with the hummer 1, the mark indicating the struck place is left on the object. Accordingly, using the hammer 1, the striking person who struck the object with the hammer 1, as well as an outsider, can clearly grasp the struck place, after the striking.  <P>COPYRIGHT: (C)2004,JPO
