The surface defect inspection method and apparatus are capable of inspecting a photosensitive material for defective surface portions with efficiency by using a reflex-type optical sensor. The surface defect inspection apparatus has a reflex-type optical sensor. A thermal-developable photosensitive material is irradiated with inspection light from a light source. Reflected light from the photosensitive material is received by a light-receiving portion of the optical sensor and a defective surface portion is detected from the reflected light. A mask is attached to the light-receiving portion to cut out specular reflected light, thereby enabling a change in the quantity of diffuse reflected light to be directly detected. Therefore, even a defective surface portion where only a small diffuse reflectance is recognized can be detected with efficiency.

In connecting a flushing port (2) of a toilet stool (1) which is formed so as to face the floor surface to which the toilet stool (1) is installed to a drainpipe (3) of the building, the connection is made by means of a flushing-side connecting pipe (6) which connects to the flushing port (2), a drain-side connecting pipe (7) which connects to the drainpipe (3), and a linking pipe (8) which makes connection between the above-noted two pipes. In making the pipe connections, the linking pipe (8) is cut off in accordance with the distance between the flushing port (2) and the drainpipe (3) or pipe insertion overlap can be used to adjust the length of the linking pipe (8).

An apparatus for mounting an electronic part includes a reflector located in the rear of an electronic part held by a nozzle on a transferring head, and an image reading device for observing an electronic part held and moved by the transferring head. The image reading device picks up an image from the electronic part. The picked-up image is recognized so as to detect a position of the electronic part with which the motion of the transferring head is controlled. The image reading device includes a line sensor for observing from below the electronic part held by the nozzle of the transferring head, a transmissive illuminating unit for irradiating light onto the reflector so as to make the background of the electronic part bright; a direct illuminating unit for irradiating from below the lower surface of the electronic part passing above the line sensor. Light obtained by emitting a band-like beam from either the transmissive illuminating unit or the direct illuminating unit and then reflecting the same upon the reflector or upon the lower surface of the electronic part is introduced into the line sensor so as to pick up an image from the electronic part attracted by the nozzle.
