Document Type and Number:
WIPO Patent Application WO/2018/150958
Kind Code:
A1
Abstract:
The present invention provides a medium transit sensing device and paired medium transit sensing devices with which, by one set of a light emission part and a photoreceptor part and at a plurality of sites upon a conveyance path, it is possible to sense a medium having a clear part and it is also possible to sense a medium having a reflective surface. The present invention provides a medium transit sensing device which optically senses the transit of a medium being conveyed within a conveyance path, said device characterized by comprising: a light emission part which is positioned to one side of the conveyance path, and which irradiates light toward the conveyance path such that an optical axis in the conveyance path forms an angle greater than or equal to 60° and less than 90° with a direction perpendicular to the conveyance path; a reflecting part which is positioned to the other side of the conveyance path in parallel to the conveyance path at a position that is separated from the conveyance path by a prescribed distance, and which reflects the light irradiated by the light emission part; and a photoreceptor part which is positioned to said one side of the conveyance path and which receives the light reflected by the reflecting part.
