Abstract: PROBLEM TO BE SOLVED: To provide a low-priced device and method which can promptly detect a detection object in different accuracy levels of demanded height detection and in the different ranges of demanded detection height provided in the same inspection object. SOLUTION: In a 'shape from defocus' system, one of projection patterns 3, 4 of different pitches in correspondence with demanded detection conditions of a detection object in a detection object 10 is inserted into an optical path of illumination lights from a light source 1. This projection pattern is projected to the detection object, and the reflected lights are received by a line sensor 12, so that images of the projection pattern in the detection object are detected. The detected images are different in the degree of focusing misalignment, in correspondence with a positional relationship between the detection object and the line sensor 12, and a height detector 15 acquires focusing measuring accuracy in correspondence with the focusing misalignment of the detection image, and a height of the detection object from this focusing measuring accuracy.  A shape of the focusing measuring precision is different between, when a projection pattern member 3 in the optical path is inserted and when the projection pattern 4 is inserted, and thus the sizes of the height detection accuracy and the height detection range are made to be different.

Abstract: PURPOSE:To prevent the continuous line switching action from generating when a trouble occurs at both lines by providing a carrier detecting means to detect a carrier on a line not to connect a MODEM when switching is executed from one side to other side of the duplicated line and switching only when the carrier is detected. CONSTITUTION:A line switching device 1 transmits the data of both lines of duplicated data lines 5 and 6 and switches so as to receive the data from one side of the lines. A change-over switch 12 is at a line 51 side, and then, a switch 15 is switched to a line 61 side and the carrier on the line 61 is inputted to a carrier detecting part 14. Consequently, a supervising part 11 supervises a carrier detecting signal from a CD signal outputted from a MODEM 2 and a carrier detecting signal from the carrier detecting part 14 and when the trouble occurs at the line 51, the CD signal is discontinued. The supervising part 11, only when the SD signal is discontinued for a constant time and the carrier detecting part 14 detects the carrier on the line 61, switches the change-over switch 12 to the line 61 side. Thus, by interlocking to this, the switch 15 is switched to the line 51 side and the line 51 is connected to the carrier detecting part 14.
