Patent number: 10536601Abstract: A controller of an information processing device changes a current state among standby states including a first standby state, a second standby state, and a third standby state, in which power consumption decreases in this order. When the non-operation duration runs for a first period, the controller changes the current state from the first standby state to the second standby state. When the non-operation duration subsequently runs for a second period, the controller changes the current state from the second standby state to the third standby state. When the sensor detects a detection target in the second standby state or the third standby state, the controller changes the current state to the first standby state. When the non-operation duration runs for a third period starting from state change, the controller changes the current state from the first standby state to the previous standby state.Type: GrantFiled: March 12, 2019Date of Patent: January 14, 2020Assignee: KYOCERA Document Solutions Inc.Inventors: Akira Ohashi, Yusuke Okazaki, Yukihiro Shibata, Satoshi Sato, Yuki Yamamoto, Koji Tagaki

Publication number: 20190324697Abstract: An image forming apparatus operates in a normal mode in a first electric power state and in a power saving mode in which more electric power is saved than in the first electric power state. The image forming apparatus includes a motion sensor, an operation section, and a controller. The controller executes a first timer process in response to receipt of the detection signal and executes a second timer process in response to receipt of the operation signal. At a time when a first period elapses indicating that the first timer process times out, the controller transitions from the normal mode to the power saving mode. At a time when a second period elapses indicating that the second timer process times out, the controller transitions from the normal mode to the power saving mode. The first period is shorter than the second period.Type: ApplicationFiled: April 17, 2019Publication date: October 24, 2019Applicant: KYOCERA Document Solutions Inc.Inventors: Yusuke OKAZAKI, Akira OHASHI, Yukihiro SHIBATA, Satoshi SATO, Yuki YAMAMOTO, Koji TAGAKI

Publication number: 20190004589Abstract: To keep up with achievement of the TEC value and suppressing the wear-out of hardware. An image forming apparatus of the present disclosure, which is configured to transit, after an elapse of a sleep-transition time, to enter a power-saving state in which power supply destinations are limited when compared to a normal state, includes a power amount prediction unit and an extension control unit. The power amount prediction unit acquires, whenever a state-transition is made, a power-consumption amount during an immediate preceding power-saving state to calculate a predicted power-consumption amount in a specific period based on the power-consumption amount. The extension control unit gives priority to the sleep-transition to enter the power-saving state if the predicted power-consumption amount exceeds the TEC value corresponding to the specific period, while extends the sleep-transition time if the predicted power-consumption amount fails to exceed the TEC value corresponding to the specific period.Type: ApplicationFiled: June 29, 2018Publication date: January 3, 2019Applicant: KYOCERA Document Solutions Inc.Inventor: Yukihiro SHIBATA
