  • Patent number: 10599371
    Abstract: 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.

  • Patent number: 10536588
    Abstract: An image forming apparatus includes a sensor, an operation section, and a controller. The sensor detects a sensor target. The operation section receives an operation instruction. The controller executes a setting process for controlling the sensor. The setting process is a process to adjust a sensitivity of the sensor according to detection precision. The detection precision is a relationship in a first unit period between the number of times the sensor detects the sensor target and the number of times of the operation section receives the operation instruction.

  • Patent number: 10536601
    Abstract: 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.
