Abstract: A method of manufacturing a watertight brushless fan motor includes first, combining a stator assembly with a stator and a circuit substrate, a case, a die, and an annular member. The stator assembly is mounted on the bearing supporting cylindrical section of the case. The bearing supporting cylindrical section is engaged and the die and annular member are fixed to the case. An insulating resin is poured into the die to mold spaces between the plate-like section and the bearing supporting cylindrical section so that the stator and the circuit substrate are included inside. The resin may be poured under low vacuum. With this arrangement, the watertight brushless fan motor is provided that can prevent occurrence of a crack in the outer surface of the molded part due to molding shrinkage of the insulating resin or expansion and shrinkage of the insulating resin caused by a change in ambient temperature.

Abstract: An image forming apparatus for forming an image comprises an attaching section, a sensor, a memory, a print section, and a controller. An ink cartridge is attached to the attaching section. The ink cartridge contains ink from a supply port on which a display member which displays a predetermined image is adhered. The sensor obtains image data of the display member adhered to the attached ink cartridge to output the obtained image data. The memory stores image data of an image displayed on the display member adhered to a genuine ink cartridge. The print section prints a desired image. The controller determines whether or not image data outputted from the sensor substantially matches image data stored in the memory to allow the print section to perform printing when both image data match each other. An ink cartridge of an image forming apparatus, which is attachable and removable to/from the image forming apparatus, contains ink from a supply port.
