Title:
COIN IMAGE ACQUISITION DEVICE, LIGHT COLLECTING COMPONENT, AND COIN PROCESSOR
Document Type and Number:
Japanese Patent JP2022145031
Kind Code:
A
Abstract:
To provide a coin image acquisition device capable of acquiring clear coin images without requiring a light diffusion film to diffuse light or a barrier to block stray light.SOLUTION: A coin imaging acquisition device for acquiring images of coins includes a light source unit that irradiates light, and an imaging unit that captures reflected images of coins irradiated by the light source unit. The light source unit includes a plurality of light emitting elements arranged in an annular shape, and a light collecting unit that collects light from the light emitting elements. The light collecting unit includes a plurality of lens arranged in an annular shape corresponding to each of the light emitting elements. The degree of collected light in the light collecting unit is smaller in the circumferential direction than in the radial direction of the annular shape.SELECTED DRAWING: Figure 2
