Abstract: A scanning module includes a body, a reflecting unit, and an image capture unit. The body includes a reflecting chamber disposed in a surrounding wall. The surrounding wall is formed with an incident hole allowing an incident light field to be transmitted into the reflecting chamber therethrough along an incident axis. The reflecting unit is disposed within the reflecting chamber, and includes a first reflector for reflecting the incident light field, as well as second and third reflectors for reflecting light transmitted from the first reflector to the image capture unit. An angle formed between the incident axis and a normal line of the first reflector is not smaller than 30 degrees. The image capture unit is disposed nearer to the incident hole than the first reflector along a direction of the incident axis, and includes a lens, and a sensing member.

Abstract: An image sensor module includes a light source unit that emits a linear light beam elongate in a primary scanning direction to an object to be read, and a lens unit including an incidence surface and an output surface oriented opposite to each other. The lens unit is configured to receive light from the object through the incidence surface and output the light through the output surface. The module also includes a sensor IC that receives the light outputted from the output surface, a housing that holds the light source unit and the lens unit, and a support member that supports the lens unit such that the incidence surface is located more distant from the sensor IC than the output surface in a secondary scanning direction.
