Title: Keyboard input device
Inventor: FURUYA TETSUO
IPC: G06F3/02
Filed: 1985-03-27
Abstract: PURPOSE:To facilitate the correction of an erroneous input by reducing the steps of key operation necessary for correcting the erroneous input due to erroneous switching of the type of a character. CONSTITUTION:Symbol (a) in figure shows data in a buffer memory 1 before correction. First time, when a KATAKANA (square form of Japanese syllabary) key and a retreat key are simultaneously pressed, a character type signal gener ating circuit 1 outputs a character type signal corresponding to the KATAKANA. Simultaneously the character type signal corresponding to HIRAGANA (cursive form of Japanese syllabary) being the immediately before character type signal is recorded in a register 8. Since the AND of voltages from the KATAKANA key and the retreat key becomes true, a correction character type code signal generator 7 generates a correction character type code signal corresponding to the KATAKANA. Assuming that the number of characters erroneously inputted is (n), the number (n) of key operation times for correction is sufficient, whereby the correction of the erroneous input can be facilitated.

Title: Method for detecting quantity of remainder toner
Inventor: MATSUMOTO KAZUHIRO
IPC: G03G15/08
Filed: 1989-03-13
Abstract: PURPOSE:To surely detect the remainder toner deficiency by checking the state of a sensor with a toner scraping member rotated to a prescribed position at the time of detecting the non-contact state with the toner scraping member separated from the sensor and judging that the quantity of remainder toner is equal to or smaller than a prescribed value at the time of detecting the non-contact state again. CONSTITUTION:Though the state of toner in a toner vessel 1 is unstable and has not reproducibility before a toner scraping member 7 reaches a certain position B after scraping toner on an oscillation face 4a of a sensor 4, toner in the toner vessel 1 is in the stable state corresponding to remainder toner after the member 7 passes this position B. That is, when the toner scraping member 7 is rotated to the prescribed position B after the non-contact state is detected at the time of separation of the member 7 from the sensor 4, the state of the sensor 4 is checked again, and it is judged that the quantity of remainder toner is smaller than the prescribed value when the non-contact state is detected again. Thus, the remainder toner deficiency is surely detected.
