发明名称 PULSE SIGNAL GENERATOR
摘要 <p>PURPOSE:To directly call user's attention by using a means to control the slip resistance due to the planar shift of a pulse signal generating device with use of an external signal and changing the slip resistance of the pulse generating device by means of an external signal. CONSTITUTION:A ball 1 which revolves with touch to a plane is used together with a detection roll 2 which revolves with touch to the ball 1 to detect the vertical shift of the ball 1, a rotary encoder 3 connected to the roll 2, a detection roll 4 which revolves with touch to the ball 1 to detect the horizontal shift of the ball 1, and a rotary encoder 5 connected to the roll 4. Furthermore a rotational resistance control plate 6 is added to control the rotational resistance of the ball 1 with a press contact secured to the ball 1 together with a solenoid 7 which changes the pressing force of the plate 6 to the ball 1. When the attention of a user is required, the slip resistance of a pulse signal generating device is changed with an external signal. Thus the resistance of the user's operating hand is changed. As a result, the user's attention can be directly drawn.</p>
