GRIP FORCE SENSATION FEEDBACK DEVICE AND STYLUS-TYPE FORCE SENSATION FEEDBACK DEVICE

摘要

According to the present invention, the size of a grip force sensation feedback device is reduced, and light and smooth operational feeling is achieved. The grip force sensation feedback device is provided with: a first rotary member which has a peripheral surface that is formed by a portion of a first virtual conical surface, and which rotates about a first cone axis; a second rotary member which has a facing surface that is formed by a portion of a second virtual conical surface and that faces the peripheral surface of the first rotary member, and which rotates about a second cone axis; a wire which are coupled, at both ends, to the second rotary member, and a central part of which is wound around the first rotary member; and a drive unit which rotates the second rotary member by rotating the first rotary member so as to provide a feedback force sensation to user's fingers in contact with the second rotary member.
