Title: Document detection device
Inventor: SATO ISAMU
IPC: G03B27/62
Filed: 1989-02-22
Abstract: PURPOSE:To easily detect a black document by combining the signals of a document detection sensor which are generated at different timing, i.e. when a pressure plate is opened and closed. CONSTITUTION:The light emitting element of the sensor 10 emits light upward at all times and the light receiving element receives reflected light from a document 2 to detect whether or not there is the document 2. Switches 4 and 5 detect the opening and closure states of the document pressure plate 3 and when the switch 4 is turned on by a lever associated with the pressure plate 3, the opening state of the pressure plate is detected to generate a timing signal. When there is no document, the light reception state of the sensor 10 changes as the pressure plate 3 is opened and closed and the light is received in both the states when the document is white and not received in both the states when the document is white and not received in both the states when white. Thus, the output of the sensor 10 in the opening state of the pressure plate 3 and the output in the closure state are combined to detect whether even the black document is present or not.
