Abstract: A contact probe can be easily mass-produced, reduce manufacturing cost, and obtain a stable contact state with an electrode such as a land of an inspection substrate. An inspection socket can be provided with the contact probe. The contact probe has a first contact terminal that contacts a solder ball of a device under test and a second contact terminal that contacts a land of a printed substrate, and a coil spring for urging contact terminals so as to separate the first and the second terminals. The first contact terminal is constituted by a first contact element formed by a rod-shaped metal member, and the second contact terminal is constituted by two second contact elements formed by a plate-shaped metal member and which clamp the first contact element in frictional contact with a part of the first contact element.

Abstract: An image-forming apparatus includes an image-forming section, a detection section, and a controller. The image-forming section has an image-bearing body on which an electrostatic latent image is formed and a developing unit that develops the electrostatic latent image. The detection section generates an output indicative of a remaining amount of toner in the developing unit. The controller drives the drive section to cause the image-forming section to move from one position to another, and determines a position of the image-forming section based on the output of the detection section. The detection section is mounted to a toner cartridge within the developing unit. When the image-forming section is moved from one position to another, the detection section receives light reflected by a high-reflectivity area and a low-reflectivity area, thereby detecting the position of the image-forming section.

Abstract: A printer uses a consumable component having an internal fuse that is blown when the consumable component is installed. In one aspect of the invention, the consumable component includes a resistor connected in series with the fuse. Before the fuse is blown, the resistance value of the resistor is checked to make sure that the correct type of consumable component has been installed. In another aspect of the invention, if the fuse fails to blow on the first attempt, this is recorded in a memory and a second attempt is made later, the consumable component being used in the meantime. In still another aspect of the invention, the consumable component includes a resistor or thermistor connected in parallel with the fuse, enabling a consumable component with a blown fuse to be distinguished from a consumable component that is not installed.
