VOLUME DETECTION DEVICE, BLISTER PACK CONTENTS DETECTION DEVICE HAVING VOLUME DETECTION DEVICE, AND HOUSING SPACE DEFINING MEMBER FOR VOLUME DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a volume detection device that can detect the volume of a detection object through the sensing performed by a light receiving part to receive the light emitted from a light source, a blister pack contents detection device having a volume detection device, and a housing space defining member for a volume detection device.SOLUTION: A volume detection device has an inner wall face 220 that defines a housing space S for housing a detection object 50, a light source 23 that emits light into the housing space S, a diffusion part that diffuses the light emitted from the light source 23, and a light receiving part 24 that receives the diffused light in the housing space S and outputs an electric signal of an intensity according to the intensity of received light.SELECTED DRAWING: Figure 11
