Abstract

A head-mounted perfume dispenser apparatus includes a processor which plays a moving image, a box, in which a container containing a perfume is received, a reservoir which is filled with the perfume received from the box and emits the perfume according to a start of playing the moving image, a tubular vent hole which vents the emitted perfume toward a nose of a user when the user wears the head-mounted perfume dispenser apparatus, and a first opener-closer provided between the box and the reservoir. The first opener-closer opens and closes according to the start and an end of the moving image played by the processor. The reservoir has a second opener-closer provided at an upper portion of the reservoir. The second opener-closer opens according to the end of the moving image played by the processor.

         4 . The head-mounted perfume dispenser apparatus according to  claim 1 , wherein
 the vent hole includes one left vent hole and one right vent hole.   
     
     
         5 . The head-mounted perfume dispenser apparatus according to  claim 2 , wherein
 the fan includes one left fan and one right fan.   
     
     
         6 . The head-mounted perfume dispenser apparatus according to  claim 1 , further comprising a fan provided above the vent hole and below the reservoir, wherein
 the fan rotates both forward and backward,   opening and closing the first opener-closer, opening and closing the second opener, starting and stopping a fan rotation, a fan rotation direction and a number of revolutions of the fan are controlled in accordance with a control signal.   
     
     
         7 . The head-mounted perfume dispenser apparatus according to  claim 6 , wherein
 the control signal is a sound signal which is included in the moving image.   
     
     
         8 . The head-mounted perfume dispenser apparatus according to  claim 6 , wherein
 the control signal is a MIDI signal corresponding to the moving image.   
     
     
         9 . The head-mounted perfume dispenser apparatus according to  claim 6 , further comprising:
 a control signal processor which generates the control signal.   
     
     
         10 . The head-mounted perfume dispenser apparatus according to  claim 6 , wherein
 the first opener-closer opens at a first time and closes at a second time according to the control signal, the first time being before a third time and the second time being after the third time and before the fourth time, the third time corresponding to a moving image play start time and the fourth time corresponding to a moving image play end time,   the second opener-closer opens at the second time and closes at a fifth time according to the control signal, the fifth time being after the fourth time,   the fan rotates forward at the first time or a sixth time according to the control signal, the sixth time being after the first time and before the third time,   the fan rotates backward at the second time according to the control signal, and   the fan stops at the fifth time according to the control signal.   
     
     
         11 . The head-mounted perfume dispenser apparatus according to  claim 3 , further comprising:
 a calculator which calculates a distance between an object in the moving image and the nose of the user based on the sensed direction and a position of the object in the moving image, the object being a source of a smell corresponding to the emitted perfume; and   a controller which changes a number of revolutions of the fan in accordance with the calculated distance.
