Abstract:
Provided is an image forming system that simply and securely protects printed matter that is not so important, but that the user does not wish others to view. An external apparatus receives a simple-security setting for image data for which there is a printing instruction, includes the simple-security setting in the printing instruction, and transmits the printing instruction to an image forming apparatus. The image forming apparatus, when a simple-security setting is included, adds a mark image to the image data for which there is a printing instruction, and prints the image data. A projector, by an imaging unit, captures an image of the discharge tray, and when a mark image is detected, generates a projection image on which a security image is arranged, and projects the projection image toward the discharge tray.
Abstract:
A mobile device includes an operation section, a storage section, a communication section which receives a position detection signal, and a processor. The processor detects a current position based on the position detection signal. The processor makes a determination on whether to give an image forming apparatus (a determination target apparatus) a return instruction to return from a power saving mode to an active mode. When it is possible to determine that a distance between the determination target apparatus and the mobile device has decreased by a distance equal to or greater than a reference distance while a moving speed of the mobile device is equal to or greater than a reference speed, the processor determines to issue the return instruction.
Abstract:
A CO2 emission estimation system includes a CO2 emission estimator. The CO2 emission estimator calculates an estimated value of CO2 emissions from an image forming apparatus when performing a job, using a CO2 emission estimation model as a formula for estimating the CO2 emissions and settings for the job. The CO2 emission estimation model is a formula where a multiple regression expression for determining an estimated value of a power consumption of the image forming apparatus when performing the job is multiplied by a CO2 emission factor. The CO2 emission estimation model has a plurality of explanatory variables each according to a different type of setting for the job.
Abstract:
A display apparatus includes a display device, a touch panel, and a control device. The control device includes a processor and functions, through the processor executing a control program, as a controller that allows the display device to display a scroll bar, on a screen of the display device, including: a body extending along a predetermined direction; and a knob disposed within the body.
Abstract:
A display/input device has a display panel, a touch panel portion, and a control portion. The display panel displays a plurality of item selection screens including selection keys for setting items. The control portion makes the display panel display item selection screens of different pages according to user operation, and recognizes a fixed key, which is a selection key on which a fixing operation has been made. When a first determination operation is done when the fixing operation is undone, the control portion makes the display panel display the item selection screen that includes the selection keys that were being displayed when the fixing operation was undone. When a second determination operation is done when the fixing operation is undone, the control portion makes the display panel display the item selection screen in which the fixing operation was made.
Abstract:
An input device includes a storage section, a display section, a touch sensor, a control section, and a display switch section. The control section switches the display state of a to-be-deleted symbol string on the display section to any one of a second half hiding state, a first half hiding state, and a full display state every time the display switch section is pressed during touch operation on the display section by a user. The second half hiding state is to hide a second half symbol string, out of the to-be-deleted symbol string, displayed behind a deletion reference position. The first half hiding state is to hide a first half symbol string, out of the to-be-deleted symbol string, displayed before the deletion reference position. The full display state is to display the to-be-deleted symbol string in full.
