Title: Image sensor
Inventor: TABEI MASATOSHI
IPC: H04N5/335
Filed: 1986-12-19
Abstract: PURPOSE:To obtain an image sensor of an interline transfer system which hardly creates booming and smears by a method wherein a transfer gate between an optoelectric transducing part and a vertical transfer CCD is composed of a vertical MOS transistor. CONSTITUTION:An optoelectric transducing part 12, a transfer gate 13 and a vertical transfer CCD 14 are formed on the surface of an n<->type semiconductor substrate 10 with a p-type well 11 between. A photodiode of which the optoelectric transducing part 12 is composed is formed with a p-n junction and an N<+>-p-n structure is formed between the photodiode and the n-type substrate. In the transfer gate 13, a V-shape groove is formed in the surface of the substrate and a MOS transistor is formed along the slopes of the groove and, as an effective channel length is determined by the depth of the groove, a leakage current fromt the photodiode can be blocked even if the integrity is high. Especially, even if an excessive light enters the photodiode, the transfer gate operates properly and makes the excessive charge absorbed by VOD. Therefore, even if a highly fine picture element is provided in the device, the leakage current from the photodiode caused by a short channel effect can be limited so that blooming and smear can be avoided.

Abstract: PROBLEM TO BE SOLVED: To make such a fact that a troublesome operation is shouldered on a user because of paper jamming, conveying failure and imaging trouble in an image former due to the occurrence of sheet skewing attributable to a paper loading failure in this sheet feeding device, obviable from occurring. SOLUTION: A claw-form gate 11 and a pair of skew sensors 12a and 12b are installed downstream in the vicinity of a grip roller 6. The occurrence of paper skewing is detected from a difference in time when a sheet tip arrives at each position of these paired skew sensors 12a and 12b. When the occurrence of paper skewing is detected, conveyance of a sheet 3 is stopped at once. With this, any possible sheet jamming and imaging trouble at the next process are obviated from occurring. The sheet detected of its skewing is removed to the outside by a user's operation. Since this work is carried out in a sheet loading part 2, a handling part is definite enough, and further the sheet is not damaged by the sheet jamming so that it takes place easily.
