摘要： Provided is a test apparatus that tests a device under test, including a vector expanding section that sequentially generates a plurality of test vectors; a predicting section that calculates a predicted value for each test vector by simulating an operation of the device under test, the predicted value indicating a prescribed characteristic value of the device under test to be measured while the device under test is supplied with a test signal corresponding to the test vector; a measuring section that obtains a measured value for each test vector by measuring the prescribed characteristic value of the device under test each time the device under test is supplied with a test vector; and a judging section that judges whether the device under test is defective based on a ratio between the predicted value and the measured value corresponding to each test vector.

摘要： An original document size detection device of the present invention is characterized by comprising a document reading table, a light source which irradiates an original document placed on the document reading table, a cover body which covers the original document, a light detection unit which detects a reflected light that a light from the light source is reflected by the original document and an external light that enters the surface of the document reading table when the cover body is lifted, a masking unit which masks an output signal based on the external light in the output signal of the light detection unit based on the reflected light and the external light, and a determination unit which determines a size of the original document in a main scanning direction based on the output signal of the light detection unit that is masked by the masking unit.
