Transmission and rapid recovery apparatus of the reading training aircraft

摘要

(57) [summary] [purpose] is to provide a transmission and rapid recovery apparatus of the fast was read training aircraft than the return speed forward speed. [Configuration] Install the transmission gear set 22 to the DC motor 21, to rotate one of the driving wheel 3 at its output. Drive wheel 3 is in contact with the follower rod 42 of the auxiliary rod 4 and the auxiliary rod 4 has a scanning rod 41, and so can slide to fit the control rod 5 there is a single groove 12 on the bottom seat 1 ing. One single switching tenon 52 on the upper side of the control rod 5 is switched are in the normal rotation or reverse rotation when the conflict with the change-over switch 6 there. Also one of the convex piece 46 is provided to close to the scanning bar 41 on the driven rod 42, when you return, it is used a control rod 5 is pushed back to the. The rotation speed of the motor 21 is adjusted by the magnitude of the voltage. The user is able to turn the pages by using a short time of restoration, can minimize the degree of disruption of learning.
