Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To realize high speed printing and the effective use of printed paper without troublesome separation in the case an instruction to cancel printing is given. SOLUTION: When instructed to print a plurality of documents, the printer repeats the process of drawing paper out of a paper feed tray 30 and carrying it, transferring a toner image formed on an image carrier 42, fixing the toner image with a fixing roller 52, and subsequently storing the paper into a paper stack tray 50. In the case the printer is not instructed to cancel the printing before the completion of the printing, only the printed paper stored in the tray 50 is ejected onto an ejection tray 72. In the case the printer is instructed to cancel the printing before the completion of the printing, on the other hand, it draws the paper out of the tray 50 in order, and detects by a blank-paper detection sensor 74 whether the back of each paper drawn out is blank or not.  The paper whose back is blank is turned over to front and stored in the paper feed tray 30, and the paper whose back is also printed is stored in a paper recovery box 80 for recycling.

Title: Solid-dtste image pickup device
Inventor: KANEDA OSAMU
IPC: H04N5/335
Filed: 1993-12-20
Abstract: PURPOSE:To obtain a solid-state image pickup device which shortens signal readout time, make possible high-speed device and reduces dark current. CONSTITUTION:A stripe-shaped n<+> region 5 is formed in the central part of a photodiode 1. One end of the n<+> region 5 is close to a transfer gate electrode 2, and the other end is situated inside the photodiode 1. A plurality of CCD gate electrodes 4 are arranged along a CCD channel 3. The transfer gate electrode 2 for charge transfer is arranged between the photodiode 1 and the CCD gate electrodes 4. Consequently, even after a signal charge has been transferred, an electric charge remains in a deep potential well which is formed in a first semiconductor layer. As a result, an increase in a time constant is suppressed, and the time spent to read out the signal charge is reduced. In addition, since a signal noise due to a dark current is reduced by a third semiconductor layer, it is possible to obtain a solid-state image pickup device which generates low noise and make possible high-speed drive.
