Title:
COMPOSITE TACTILE SENSOR
Document Type and Number:
Japanese Patent JPS60195431
Kind Code:
A
Abstract:

PURPOSE: To detect as face information contact of an object and pressure by the object, by providing a pressure receiving part having a projection, etc. on a light reflecting system sensor.

CONSTITUTION: Many light sources 2 are arranged on a substrate 1. A sensor substrate 3 is provided so as to be opposed to this substrate 1, and on this sensor substrate 3, a photodetector 4 is provided at a pitch equal to the light source 2. Also, a pressure receiving part 6 is constituted of a soft part 7 and a light reflecting film 8, and the soft part 7 has a columnar projecting part 9 having a large sectional area and a columnar projecting part 10 having a small sectional area. In this state, in case a force is applied to the pressure receiving part 6, a degree of deformation of the light reflecting film 8 is varied in accordance with the applied force. Also, a light from the light source 2 is reflected by the light reflecting film 8, made incident to the photodetector 4, and converted to an electric signal.
