<p><P>PROBLEM TO BE SOLVED: To improve electric driven toy gun with a new electric mechanism and a unit and make a small gun to be driven by electricity. <P>SOLUTION: Accompanying a trigger, a single/continuous-shot switch unit for switching a single shot action to a continuous shot action is newly provided. A trigger switch is operated by pulling the trigger and a single shot action is conducted by a motor, and the trigger is pulled with stronger force beyond a preset separation wall spring to structure a parallel circuit with the trigger switch and a control switch and continuous shot continues while keeping the trigger pulled. When the trigger is returned, a relay is recovered at the same time and a motor connection point moves from a positive connection point to a negative connection point and positive electric load of the motor is simultaneously grounded and discharged. Then, the motor is immediately stopped, unnecessary rotation of a final driving gear is prevented and the single shot and the continuous shot is finished. As a shot by a human finger takes 0.35 seconds at best, rotation ratio of a pinion and the final driving gear is set so that the single shot action finishes in 0.2 seconds. Large driving force is provided from relation of rotation speed of the gear and force efficiency and bullet energy of almost 0.8 joule is enabled to be generated. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
