A medium detection device that detects a medium conveyed across between the light emitting section and the light receiving section,
The support plate along the surface of which the medium is conveyed includes:
An opening through which the sensor is inserted and a window hole located near one edge of the opening are formed, and the sensor is inserted through the opening and connects the light emitting part and the light receiving part. is installed so as to straddle the one end edge of the opening and face the window hole, and the back surface of the one end edge of the opening and the light emitting section or the light receiving section facing the back surface are connected to each other. A sensor cover made of a translucent material is interposed between the sensor cover and the sensor cover, which fits into the window hole and has an end surface substantially flush with the surface of the support plate. A medium detection device characterized in that a light guiding protrusion is integrally formed. (2) A photo-interrupter type sensor that integrally has a light-emitting part and a light-receiving part facing each other,
A medium detection device for detecting a medium conveyed across the space between the light emitting section and the light receiving section, wherein a surface side of the support plate along which the medium is conveyed is provided with a support plate for detecting the medium. A medium guide is fixed to guide the end, and the support plate has an opening through which the sensor is inserted, and a first window hole located near one edge of the opening. The medium guide has a second window hole opposite to the first window hole, and the sensor has one of the light emitting section and the light receiving section on the back side of the support plate. , the other one is inserted into the opening so that it is located on the outer surface side of the medium guide, and the one side faces the first window hole from the back side thereof, and the other side is inserted into the second window hole. The sensor cover is installed so as to face the hole from its outer surface, and a sensor cover with a U-shaped cross section made of a translucent material is attached between the light emitting part and the light receiving part of the sensor. A pair of light guides are provided on the inner surface of the sensor cover and fit into the first and second window holes and whose end surfaces are substantially flush with the front surface of the support plate and the back surface of the medium guide. A medium detection device characterized in that a protrusion is integrally formed. (3) The medium detection device according to claim 2, wherein a holder portion of the sensor is integrally formed with the medium guide.
