A sheet discharging apparatus includes a first discharge unit and a second discharge unit configured to discharge a sheet respectively, a first stacking unit configured to stack the sheet discharged by the first discharge unit, a second stacking unit disposed below the first stacking unit, and configured to stack the sheet discharged by the second discharge unit, a lifting unit configured to lift and lower the first and second stacking units, and a control unit configured to perform a separation process of moving at least one of the first and second stacking units so as to increase a distance between the first and second stacking units in a vertical direction in a case where a matter has come into contact with a lower surface of the first stacking unit.

A sheet discharging apparatus includes a first stacking unit to stack a sheet discharged by a first discharge unit, a second stacking unit disposed below the first stacking unit to stack the sheet discharged by a second discharge unit, and a lifting unit to lift and lower the first and second stacking units. A detection unit changes an output value based on contact of a matter with a lower surface of the first stacking unit, and a distance estimation unit estimates a distance between the first stacking unit and the second stacking unit. A separation process lifts the first stacking unit to increase a distance between the first and second stacking units in a vertical direction in a case where the output value changes based on contact of the matter with the lower surface of the first stacking unit and the estimated distance being smaller than a threshold value.

An information processing apparatus capable of resetting the system when a sub CPU abnormally operates. A controller includes a main CPU for controlling operation of the system and a sub CPU for controlling operation of specific internal devices. A first WDT circuit and a second WDT circuit are set to a first timer time and a second timer time according to respective reset signals received from the sub CPU. According to a first interrupt signal output from the first WDT circuit based on expiration of the first timer time, the second timer time is controlled to be extended to a predetermined time and execution of a process for rebooting the controller is controlled. According to a second interrupt signal output from the second WDT circuit based on expiration of the extended second timer time, execution of a process for resetting the system is controlled.

A image forming apparatus includes a power control unit, an operation mode control unit, and a first timer. The power control unit performs control so as to switch between a normal power state for supplying the operation power supply voltage to the image forming unit, a first power saving state for not supplying the operation power supply voltage to the image forming unit, and a second power saving state having less power consumption than the first power saving state. The operation mode control unit performs control so as to switch a normal mode corresponding to a normal power state, a first power saving mode corresponding to a first power saving state, and a second power saving mode corresponding to a second power saving state.

An image forming apparatus reads a document mounted on a document positioning section by using an image reading section, and forms an image of the document on a sheet by using an image forming section. The sheet subjected to the image formation processing is mounted on a discharge tray via a discharge section. The image forming apparatus includes an operation unit that has a touch panel and that protrudes from a front portion of the image reading section, and a power button that is a hardware button provided on a back side of the operation unit and on a front portion of the image reading section

An image communication apparatus has, as operation states, a first power state and a second power state with lower power consumption than the first power state. The apparatus comprises a ringing unit that rings according to an predetermined incoming signal from an external; a setting unit that sets whether the ringing unit rings according to the predetermined incoming signal or not; and a control unit that shifts the operation state from the first power state to the second power state based on at least the setting set by the setting unit.

A CPU of a printer requests a first external device to supply electric power via a first interface through communications according to the USB standard. When the CPU determines that the requested electric power is to be unsupplied from the first external device, the CPU requests a second external device to supply the electric power via a second interface.

Provided is a printing device that performs printing using a recording material, the printing device including: an capacitive touch panel; a home operation portion including a mechanical key for transitioning from a screen displayed on the capacitive touch panel to a basic screen including information on a remaining amount of the recording material; and a power supply operation portion including a mechanical key for shifting a power state of the printing device, in which a panel installation surface provided with the capacitive touch panel is a surface different from a power supply operation portion installation surface provided with the power supply operation portion.

An image reading device includes: an original-document table at which an original document is mounted; a reading unit configured to read the original document mounted at the original-document table; an opening/closing section configured to be able to open and close the original-document table; a power source configured to apply power for opening and closing to the opening/closing section; a proximity sensor configured to output a detection signal in accordance with approach of a detection target; and a control unit configured to control the power source on a basis of the detection signal from the proximity sensor.

A CPU of an MFP receives battery information from a first external device via a first interface, determines whether a total amount of electric power supplied to a plurality of interfaces from a power supply is maintained, and reduces an amount of the electric power supplied to the first external device via the first interface in a case where determining that the first external device has no battery based on the battery information in response to determining that the total amount of the electric power supplied to the plurality of the interfaces from the power supply is not maintained.
