A fault detection apparatus of a power source provided with a central processing unit, a power source, a power receiver supplied with current from a power source, a unit periodically accessing the power receiver from the central processing unit so as to supply a periodic current periodically repeatedly turning on and off from the power source to the power receiver, and a unit judging the power source to be defective when the output voltage of the power source exceeds a predetermined threshold value and a method and program for the same. By this, it is possible to judge a power source to be defective when fluctuations in the output voltage of a power source due to the periodic supply of current to the power receiver (voltage load fluctuations) exceed a predetermined threshold value.

Obtained is a passenger conveyor that, in the case of the elongation of a step chain of the passenger conveyor, causes a hydraulic cylinder to move a lower-part step chain wheel, thereby absorbing a slack in the step chain and tensioning the step chain with any push-out force. In a passenger conveyor provided with a step chain tensioning device that, in the case of the elongation of a step chain, causes a lower-part step chain wheel to move, thereby absorbing a slack in the step chain and tensioning the step chain with any tensioning force, the step chain tensioning device includes a tensioning device section, which has a hydraulic cylinder and pushes out the lower-part step chain wheel with a push-out force of the hydraulic cylinder on a side where the step chain is tensioned, and a pressure device section, which has a pressure piston to which a load by a weight is applied and causes the hydraulic cylinder of the tensioning device section to constantly give any tension to the step chain via a hydraulic oil due to the pressure of the pressure piston.

A table having a plurality of holding portions for holding recording heads to be tested is arranged to be pivotal between a printing position and a changing position, so that the recording head located at the changing position can be changed during estimation of the recording head located at the printing position. An estimation pattern in which dots are arranged so as not to contact each other is printed on a recording medium. The printed estimation pattern is read by an image pick-up device, and character amounts in units of dots are extracted from image data obtained by the image pick-up device. Pattern estimated values are calculated according to the dot character amounts and are used to judge whether the recording head is normal. Another printed pattern is read by the image pick-up device, and an edge image is extracted from density image data obtained by the image pick-up device. After enlargement/reduction processing is performed for the edge image, an edge image is extracted again. Shape character values in units of areas separated by edge lines of the edge image are obtained, and the pattern and any stain are discriminated based on the shape character values, thereby detecting a stain state. A one-dimensional average density in the line direction of the pattern is obtained from the density image data, and a line width is obtained based on the average density. A stain is detected on the basis of the line width.

An optical apparatus (23) for emitting light is constituted by a fixation holder (8) fixed to a predetermined positioning fixation jig via a fixation plate (8a), a lens-barrel (10), fitted on a cylindrical portion of the fixation holder (8) via an annular gap (19), and formed of a transparent material, for holding a collimator lens (2), and a semi-conductor laser light source (1) fitted under pressure in the fixation holder (8). An ultraviolet curing adhesive (18) is uniformly filled in the gap (19). Before the ultraviolet curing adhesive (18) is cured, the lens-barrel (10) is movable in an optical axis direction (Z) and in two-dimensional directions (directions of arrows X and Y) on a plane perpendicular to the optical axis direction (Z) with respect to the fixation holder (8).
