A line sensing stick is provided to be used to help a blind person to walk safely and to prevent accidents of users by attaching sensors for sensing the color on the bottom of a simple stick and letting the sensor decide separation from inducing blocks. The lower part of a line sensing stick is divided into four parts. A space in which a motor and a battery are put is formed in the upper space of the stick having a length of 10cm. Part-a is a switch and is operated only when it is necessary for a walker. Part-b is a switch for fixing the stick when a user folds or unfolds the stick. In the lower part of the line sensing stick, sensors are disposed with a space between each other to sense the separation of a line. A radiating element emits infrared ray periodically, and a light receiving element reads the line with the infrared ray reflected from the bottom.
