  • Publication number: 20030142491
    Abstract: A flashlight in which a switch main body may be easily assembled by fitting parts for a top surface of the switch main body to be pushed upwardly for automatically and closely contacting an inside of the flashlight without using any additional element, and a lens is closely fixed to a reflection mirror of a head part so that the vibration may be prevented and the waterproof effect may be obtained, thereby improving the productivity and the reliability of the products. In the flashlight, a switch cover of the switch main body is integrally formed with a semicircular insertion plate, an upper body is formed with cut parts at both sides for matching an insertion plate of the switch main body with the cut parts, so that the insertion plate is inserted along the cut parts as a force is applied to the insertion plate, thereby simply assembling the switch main body into the flashlight.

  • Patent number: 6144393
    Abstract: An image forming apparatus includes an exposing unit for performing exposure by scanning a beam to a photosensitive belt to form an electrostatic latent image, a developing unit for forming a toner image by supplying liquid toner to the electrostatic latent image formed by the exposing unit, a sensor for detecting the position of the toner image formed on the photosensitive belt, and a controller for calculating a positional error by comparing the position detected by the sensor with an established reference position and controlling exposure performed by the exposing unit to correct the calculated positional error. Thus, since errors between the established scanning position and the actual scanning position are automatically corrected during scanning, the scanning can be performed more precisely and conveniently.
