         2 . The pendulum type golf putting practice device according to  claim 1 , wherein the putting guide device comprises a putting guide pendulum having the light-emitting device at one end and having rotary motions around the other end. 
     
     
         3 . The pendulum type golf putting practice device according to  claim 2 , wherein a rotating direction and rotation angle of the putting guide pendulum are adjusted by means of a motor. 
     
     
         4 . The pendulum type golf putting practice device according to  claim 1 , wherein the putter sensing device comprises either a plurality of optical sensors or a plurality of proximity sensors for detecting a movement of the putter head. 
     
     
         5 . The pendulum type golf putting practice device according to  claim 1 , wherein the alerting information device comprises at least one of a speaker and a monitor. 
     
     
         6 . The pendulum type golf putting practice device according to  claim 1 , wherein the alerting information device comprises a LED. 
     
     
         7 . A pendulum type golf putting practice device, comprising:
 a putting guide pendulum having a light-emitting device at one end for emitting light to a putter head in such a manner as to guide a swing path and swing speed of a putter and having rotary motions around the other end;   at least one sensor being mounted on the putter head for detecting the emitted light; and   an alerting information device for informing about an occurrence of a putting error if the emitted light was not detected during guidance of the swing path and swing speed of the putter.   
     
     
         8 . The pendulum type golf putting practice device according to  claim 7 , wherein the swing path of the putter includes a back swing path and a follow swing path and the putting guide pendulum guides the back swing path using a rotation angle of the direction opposite to a putting direction and guides the follow swing path using a rotation angle of the putting direction. 
     
     
         9 . The pendulum type golf putting practice device according to  claim 7 , wherein the swing speed of the putter includes the speed of the backswing and the speed of the follow swing and the putting guide pendulum guides the backswing speed by using a rotation speed opposite to the putting direction and guides the follow swing speed by using a rotation speed of the putting direction. 
     
     
         10 . The pendulum type golf putting practice device according to  claim 7 , further comprising:
 a control device for adjusting, depending on information of a putting condition including a putting distance, at least one of the rotation speed and angle of the putting guide pendulum rotating opposite to the putting direction, and the rotation speed and angle of the putting guide pendulum rotating in the putting direction.   
     
     
         11 . The pendulum type golf putting practice device according to  claim 7 , further comprising:
 a wireless transmitter being installed with the at least one sensor on the putter head, the wireless transmitter for transmitting information about the sensor's detection of the emitted light to the alerting information device.   
     
     
         12 . The pendulum type golf putting practice device according to  claim 7 , wherein the alerting information device is installed on the putter. 
     
     
         13 . The pendulum type golf putting practice device according to  claim 7 , wherein the at least one sensor for detecting the emitted light comprises a plurality of sensors. 
     
     
         14 . The pendulum type golf putting practice device according to  claim 13 , further comprising:
 a swing error analyzer for analyzing swing errors using a pattern of the plurality of sensors that detect the emitted light during the movement of the putter.   
     
     
         15 . The pendulum type golf putting practice device according to  claim 14 , further comprising:
 a wireless transmitting device for transmitting identifiers of the plurality of sensors detecting the light during the movement of the putter to the swing error analyzer wherein an identifier is provided to each of the plurality of sensors.   
     
     
         16 . The pendulum type golf putting practice device according to  claim 14 , wherein the plurality of sensors are arranged in the putting direction and the swing error analyzer analyses swing errors in the putting direction. 
     
     
         17 . The pendulum type golf putting practice device according to  claim 14 , wherein the plurality of sensors are arranged in the vertical direction to the putting direction and the swing error analyzer analyses swing errors in the vertical direction to the putting direction.
