Title: Fluorescence reader
Inventor: ISHIDA KAZUYUKI
IPC: G01J1/58
Filed: 1987-07-10
Abstract: PURPOSE:To improve the S/N, by performing a detecting operation with a fluorescence detector when light from a light source is not irradiated after the excitation of a fluorescent substance to eliminate excitation light, reflected light on a background and interference of the excitation light at the detection of fluorescence. CONSTITUTION:When a pulse light source 1 emits a pulse light for excitation by a signal from a timing controller 13, excitation light is incident into a light guide 2 efficiently. The excitation light turns to an excitation light flux 7 passing through the light guide 2 to excite a fluorescent substance 10 so that fluorescent emission begins from the fluorescent substance 10. When the light source 1 is turned off with the controller 13, the fluorescent emission lasts still after the excitation light fails as the life of the fluorescence 8 last long to a certain extent and hence, fluorescence alone is taken into the light guide 3. A fluorescence detector 4 converts the fluorescence into an electrical signal to be sent outside as signal output. This eliminates reflected light on a background and interference of excitation light thereby improving the S/N.

Abstract: PURPOSE:To prevent a pool of liquid developer in a transfer nip part, to obtain a satisfactory image and to reduce color mixture, which is caused via a transfer belt, by selectively supplying the liquid developer to the transfer nip part by the use of a liquid developer adjustment means. CONSTITUTION:A bias power source control means composing the liquid developer adjustment means together with a bias roller 11 applies a bias to a bias roller 11 when a transfer paper detection means 12 does not detect transfer paper, and does not apply a bias to it when it detects the transfer paper. The bias roller 11 rotates accompanying the rotation of a photosensitive drum 1, and squeezes the liquid developer on the photosensitive drum 1 by applying a bias by the use of the bias power source control means when the transfer paper on the transfer belt 2 has not been carried to the transfer nip part 3 although a visible image on the photosensitive drum 1 has been carried to the transfer nip part 3. Thus, the liquid developer is prevented from being supplied although the transfer paper does not exist in the transfer nip part 3.
