Abstract: An input device includes a touch panel, a touch button, a first measurement device, a second measurement device, a first detection device that detects a touch position of an operating body on the touch panel, based on a difference between the electrostatic capacitance measured by the first measurement device and a panel baseline value, a second detection device that detects a touch operation on the touch button, based on a difference between the electrostatic capacitance measured by the second measurement device and a button baseline value, an error decision device that decides that the touch operation is an error, when the touch operation detected by the second detection device satisfies a predetermined condition, and a controller that sets the button baseline value to an initial value, when the error decision device has identified an error, and sets the panel baseline value to an initial value, when the error decision device has not identified an error.

Abstract: An image forming system includes a recording processing portion, an acquirement processing portion, and an output processing portion. The recording processing portion records a consumed amount of a consumable consumed by an image forming apparatus per predetermined unit time. The acquirement processing portion acquires prediction data that indicates a predicted consumed amount of the consumable per the unit time for a time period from a predetermined standard time, based on a comparison result between: a first record result corresponding to a first time period extending to a reference time; and a second record result corresponding to a predetermined second time period extending to the standard time, among a record result recorded by the recording processing portion, the reference time being a predetermined specific time period earlier than the standard time. The output processing portion outputs the prediction data acquired by the acquirement processing portion.

Abstract: A disconnection time acquisition system includes a response requesting circuit, a response determining circuit, a response circuit, a time storage circuit, and a time management circuit. The response determining circuit, in a network server, determines whether or not a response signal in response to a response request signal is received. The response circuit, in an electronic device, replies the response signal in response to the response request signal to the network server. The time storage circuit, in the network server, stores a time without the response signal when the response signal in response to the response request signal is not received. The time management circuit manages the time without the response signal as a disconnection time at which a power supply of the electronic device is disconnected when the power supply of the electronic device is turned on.

Abstract: The device is constituted so that, when a non-processing period continues for more than a predetermined time in a normal mode, in which an image forming process is possible, the image forming device switches to a power saving mode, in which power consumption is reduced, two types of LEDs 8a and 8b that have display colors that differ from one another being provided, and each light source 8a and 8b being selectively illuminated by the mode notification means 13 according to the normal mode and the power saving mode.

Abstract: A photocopier 1 according to this embodiment of the invention automatically detects the position of a staple 52 from the image data of the front page 51 of a bound original document 50; automatically sets a replacement area for the staple 52 portion or binding margin 54 portion to be replaced according to the position of the staple 52, and a replacement color that is the color of the mask data element substituted for the data element of the replacement area, based on the image data for each page of the original document 50; and then converts the data element of the replacement area portion of the original document 50 image data to the mask data element of the replacement color before printing copies.
