Filed: 2014-09-10
Abstract: PROBLEM TO BE SOLVED: To solve the problem of noise, in a thermal fixation-type apparatus which fixes a toner image after preheating, caused by a fixation motor being driven to rotate various rollers not only when the apparatus is switched on but also when the apparatus recovers from a sleep state.SOLUTION: An image forming apparatus detects the temperature of a fixation film of a fixation unit to confirm whether or not the image forming apparatus has recovered from a sleep state. When the recovery from the sleep state is confirmed, the image forming apparatus compares the detected temperature of the fixation film with a prescribed threshold. When the temperature of the fixation film is less than the prescribed threshold as a result of the comparison, the image forming apparatus performs a control to preheat the fixation film by electrifying a heater for heating the fixation film in order to thermally fix a toner image transferred on a recording medium. On the other hand, when the temperature of the fixation film is the prescribed threshold or more, the image forming apparatus performs a control not to electrify the heater.SELECTED DRAWING: Figure 4

Filed: 2014-10-22
Abstract: PROBLEM TO BE SOLVED: To provide an autonomous position identification system in which plural measurement systems cooperate with one another while upgrading their availability ratios and which identifies an origination source position of a signal whose reliability is evaluated.SOLUTION: When plural measurement systems disposed at different positions collaborate with one another in measuring an azimuth of a signal, all the measurement systems do not concurrently note and measure the same signal, but receive signals on the basis of the individual settings of the respective measurement systems, and continue recording the signals. Meanwhile, in response to a signal azimuth measurement request from any measurement system, one measurement system reproduces a record preserved in the own measurement system and measures an azimuth. For identifying an origination source position of a signal, the plural measurement systems collaborate with one another in calculating a candidate for the origination source position using the measured azimuth. The reliability of the candidate for each position is calculated and evaluated using an accuracy of a measured value obtained at the time of measuring the azimuth, and a weight dependent on the accuracy of azimuth measurement obtained immediately close to the measurement system that has measured the azimuth.SELECTED DRAWING: Figure 1
