Abstract:
This reading device (20) is provided with a housing (21), a first irradiation unit (27a), an imaging device (26), and a first diffusion unit. The housing (21) has an opening at an upper part thereof, a transparent reading window member (22) being arranged in the opening. The first irradiation unit (27a) radiates an infrared ray. The imaging device (26) is arranged, on a bottom part inside of the housing that faces the upper part, so that the optical axis is oriented toward the reading window member (22). The first diffusion unit is arranged on a left-side wall that connects the upper part and the bottom part inside of the housing (21). The first diffusion unit diffuses the infrared ray from the first irradiation unit. The first diffusion unit is configured from a light-transmitting-type first diffuser plate (24a) and a light-transmitting-type first diffuser plate (24b). The first diffusion plate (24a) is arranged on the bottom-surface side of the left-side wall so as to be inclined in a direction toward the upper part. A second diffusion plate (25a) is arranged on the upper-surface side of the left-side wall so as to be inclined in a direction toward the bottom part.
