Title: Ink jet recording apparatus and ink detection method therein
Inventor: ONO TAKASHI
IPC: B41J2/01
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To shorten the time for detecting the emission of ink from an ink jet head by emitting ink corresponding to the detection by a detection means and investigating the detection signal in synchronous relation to the emission of ink to judge the presence of the emission of ink. SOLUTION: In order to shorten the time required in the detection of ink, ink is emitted to the gap between the photointerrupters of an ink detection part 8 while a recording head 5 is moved without being stopped to detect ink. A signal is usually a low level because a phototransistor 102 is turned ON and, by emitting ink to the gap between a light emitting element 101 and a photodetector 102, light is emitted from the light emitting element 101 and the quantity of the light reaching the photodetector 102 is reduced and the current flowing to the phototransistor 102 is reduced. By this constitution, the amt. of the ink emitted from the recording head 5 is detected. Ink is emitted while the recording head 5 is moved at a speed A and, when no ink is detected, ink is detected at a slower speed B.

Title: Original reading device
Inventor: MORIZAKI HIROSHI
IPC: H04N1/04
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To automatically adjust and set which part should be selected as a reading area when there is a little deviation included in the range of valid pixels by judging whether or not reading magnification is normal based on the information of a mark included in a signal at the time of reading a white member. SOLUTION: A signal voltage outputted from each CCD pixel is made larger according as received light quantity is made large so that a high signal voltage can be outputted from pixels in an area at the time of reading a white member 14 on which much lights irradiated from an LED are reflected. Also, low voltage signals are outputted from pixels in an area in which any white member 14 is not present or areas corresponding to black straight lines (marks) 15a and 15b. A signal processing circuit converts each pixel data into white and black binarized data based on the change of the output signals, and outputs the data to a CPU. Therefore, it is possible to easily and accurately inspect whether or not the reading magnification is proper without any help.
