Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To decide different vehicle kinds which were considered to be identical before through simple constitution by providing a distance measuring means which is provided above a road surface where vehicles pass and measures the distance to the top surface of a vehicle. SOLUTION: One more photoelectric or ultrasonic type distance measuring sensor 3 are installed above a vehicle travel path 2, and a signal processor 4 processes signals from those distance-measuring sensors 3. Then when a vehicle comes to below a gate 1, the distance-measuring sensors 3 measure the height-directional distances between the distance-measuring sensors 3 and vehicle 6. The height of an automobile is less that the height of a bus or truck, Further, buses are constant in height, and the detected distances of the distance measuring sensors 3 become nearly constant. Trucks, however, have large differences in height, specially, between driver's seats and the decks and unlike buses do not become constant in height. Differences in feature with vehicle kinds are used as feature quantities to discriminate an automobile a truck, and a bus.

Abstract: PURPOSE:To make the drum of a photoreceptor smaller by making the spacing between the end parts other than the image-forming region of the photoreceptor smaller and destaticizing the charges remaining at the leading end part of the photoreceptor in the electrophotographic apparatus which simultaneously energizes transfer and toner destaticization. CONSTITUTION:A corona discharger 6 for transfer then a corona discharger 7 for toner charging, destaticizing lamp 8, etc. are subsequently disposed on a photoreceptor 1. The dischargers 6, 7 for transfer and toner charging are connected to the same power source device 10. Now, when the trailing end b of the photoreceptor 1 passes the corona discharger 7, the power source 10 goes OFF and the corona dischargers 6, 7 stop. At this time, already charges remain near l the leading end of the phtoreceptor 1. However, the destaticizing lamp 8 goes ON when the leading end a of the photoreceptor 1 arrives at the lamp 8 and goes OFF when the c part of the photoreceptor 1 passes. This results in that the residual charges near the leading end part of the photoreceptor is destaticized by the lamp 8, thus the end part spacings a, b other than the image-forming region of the photoreceptor may be made smaller. Hence, the drum diameter may be made smaller.
