Title: Residual toner detector
Inventor: YAMADA KAZUNARI
IPC: G03G15/08
Filed: 1987-06-30
Abstract: PURPOSE:To detect the residue of toner in a hopper with slight errors by fitting a piezoelectric sensor on the bottom surface of a hopper. CONSTITUTION:The piezoelectric sensor 13 is fitted on the bottom part of a toner hopper 8 with its detection surface set upward. When the time required for one turn of an agitator 11 is denoted as T, the weight of toner is detected in a time t1, but the sensor does not detect the weight in a time (T-t1), so toner is supplied continuously and the residue reaches a constant value; when the sensor 13 does not detect the weight of the toner continuously any more, a toner end signal is sent out. This sensor 13 is provided where the thin plate member 11a of the agitator 11 passes, and neither the blocking nor the bridge formation of the toner is caused, so a detection error is small. In an actual use state, the toner is supplied to the developing device, so every time the agitator rotates, a value t1/T is read several times continuously and their mean value is calculated to reduce the error.

Abstract: PURPOSE:To maintain or protect the secrecy of printed contents by providing an auxiliary electrode in direct contact with a resistance layer of an ink ribbon at the take-up side, so that the printed contents from which the ink is peeled off after printing through melting of the ink cannot be read with no traces remained. CONSTITUTION:A return electrode 5 is provided opposite to a take-up reel 4, and an auxiliary electrode 6 is placed normally in contact with the outer periphery of an ink ribbon 2 wound up by the take-up reel 4. A printing current I runs to the return electrode 5 from a resistance layer 7   a conductive layer 8   the resistance layer 7 of the ink ribbon 2. When an auxiliary current If is supplied from a driver circuit to the return electrode 5 through the resistance layer 7, conductive layer 8 and the resistance layer 7 of the ink ribbon 2, the temperatures of the heat generated at portion B are raised and accordingly an ink layer 9 at the side of the take-up reel 4 is melted without fail by the above-described currents I and If. Therefore, the traces that the ink was peeled off after printing disappear. Thus, the secret contents can be protected from the eyes of a third party when secrecy is necessary.
