Tactile reading device.

摘要

This invention discloses a tactile reading device including sensing rods (3) that are supported to be vertically movable, piezo-electric actuating elements (6) disposed in the vertical direction such that their free end portions (6a) are directed upward, and pushing-up cams (5) having first levers (5a) which are axially and pivotally supported on support rods (4) provided at an upper position of the free end portions (6a) of the piezo-electric actuating elements (6), extending downward from the support rods (4), and having side surfaces at distal end portions thereof which are freely abutted against the free end portions (6a) of the piezo-electric actuating elements (6), and second levers (5b) extending horizontally from the support rods (4) and freely mounting, on their mounting planes (5d), lower end portions of the sensing rods (3) corresponding to the piezo-electric actuating elements (5). <IMAGE>
