A sheet conveying device includes: a conveying unit configured to convey a sheet along a conveying path; a switching unit configured to switch a sheet conveying destination; a delivering unit configured to deliver the sheet on the delivery path toward a device at the sheet conveying destination; a reversing unit configured to first convey the sheet from the reversing port toward the outside of the casing to a position in which a part of the sheet protrudes and deliver the sheet from the position toward a circulation path while reversing the conveying direction of the sheet; a circulating unit configured to convey the sheet delivered toward the circulation path along the circulation path and return the sheet to the conveying path while the sheet is reversed; and a control unit configured to control the reversing unit when a jammed sheet is detected in the device at the sheet conveying destination.

Sheet conveying device, and image forming apparatus and image forming system including the same

An image content display system includes: a display device; a display controller that displays image content on the display device while switching a plurality of sets of image content; and an image forming apparatus that prints image information associated with image content displayed on the display device, wherein the display controller includes a first acquiring unit that acquires image content of a first content group, a second acquiring unit that acquires image content of a second content group, a determining unit that determines whether or not the image forming apparatus is in a printing enabled state, and a display control unit that displays the image content of the first content group, and switches image content to be displayed on the display device from the image content of the first content group to the image content of the second content group.

Image content display system and display controller

An image forming apparatus includes a time setting unit that sets a print allowable time according to the amount of advance payment, a usage time count unit that counts a usage time and a print allowance determination unit that determines, from the time setting unit and the usage time count unit, whether printing is allowed or prohibited. Before the time counted by the usage time count unit reaches the print allowable time, the print allowance determination unit allows the printing to be performed whereas after the time counted by the usage time count unit reaches the print allowable time, the print allowance determination unit prohibits the printing from being performed.

Image forming apparatus

An image forming apparatus includes: a sensor that detects discontinuation of printing or a decrease in print speed; and an electric circuit configured to set an available time to print according to an amount of advance payment; count a usage time during which the image forming apparatus is used; determine permission or prohibition of printing based on the available time to print and the usage time; determine whether to count the usage time based on a factor for the discontinuation of printing or the decrease in print speed when the sensor detects the discontinuation of printing or the decrease in print speed; and prohibit printing when the counted usage time reaches the available time to print.
