Title:
OPTICAL INFORMATION READING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/009258
Kind Code:
A1
Abstract:
Provided is an optical information reading device (10). This device is provided with: a reflection member (50) that reflects illumination light (Lf) projected from an illumination light source (21) toward a reading plane (14); and an image formation part (27) configured such that an imaging object held over the reading plane falls within an imaging range of an imaging part (23). When, within the imaging range, a range formed between the image formation part and the reading plane is defined as a first imaging range (AR1), and a range formed between the reading plane and the reflection member so as to be continuous with the first imaging range (AR1) when the illumination light is reflected to the inside of a housing by the reading plane is defined as a second imaging range (AR2), the reflection member is disposed at a position outside the first imaging range, and the illumination light source, the imaging part and the image formation part are disposed at positions outside the second imaging range. The illumination light source projects the illumination light toward a reflection plane 55, which falls within the second imaging range, of the reflection member. Incidentally, it is preferable that, on the upper surface of the housing of the device (10), an operation part and a display part be disposed in a surface portion on one end side continuous with one side of a reading port.
