Abstract

A sheet sensor 1 is provided for use in a sorter or simi~ lar type device. ~pically such sheet sensor consist of a light source directed at a phototransistor mounted behind a lens assembly. It is proposed to provide a one~-piece plastic moulding 2 for mounting phototransistor 3, lens assembly 4, and mirror 5~ By introducing the mirror 5 into the light path the light source 6 may be positioned at a right angle to the phototransistor 3. This arrangement provides a simple and compact sensor with the advantage of right angle mounting of the components. The path of a sheet is between the lamp 6 and the detector assembly 2.
