Abstract: A keyboard slide mechanism for use in a keyboard that is so structured that key tops are raised and lowered as a sliding member is slid has a rotary member that can be rotated, converting means for converting the rotating movement of the rotary member into translating movement, and movement magnifying means for magnifying the translating movement produced by the converting means. The key tops are raised and lowered by converting the rotating movement of the rotary member into translating movement with the converting means, then magnifying the translating movement with the movement magnifying means, and then transmitting the magnified translating movement to the sliding member.
