Abstract
In accordance with an embodiment, a sheet taking away determination system comprises a first detection device configured to detect a sheet discharged to a discharge port; a second detection device configured to detect a terminal device positioned within a communication enabled range of the second detection device; and a controller configured to determine that the sheet is taken away if the second detection device detects the terminal device and a quantity of the sheets is less than that of the sheets before detection after the sheet is detected by the first detection device.
Claims20
A sheet removal determination system, comprising:
- a first detection device configured to detect a sheet discharged to a discharge port;
- a second detection device configured to detect a terminal device positioned within a communication enabled range of the second detection device;
- and
- a controller configured to identify a user based on user information acquired from the terminal device detected by the second detection device, determine that the sheet has been removed by the user if, before detection of the terminal device by the second detection device, a first quantity of sheets being detected by the first detection device is less than a second quantity of sheets detected by the first detection device.
A sheet removal determination method, comprising:
- detecting a sheet discharged to a discharge port;
- detecting a terminal device positioned within a communication enabled range;
- identifying a user based on user information acquired from the terminal device;
- and
- determining that the sheet has been removed by the user if, before detecting the terminal device, a first quantity of sheets is less than a second quantity of sheets as detected at the discharge port.
An image forming apparatus, comprising:
- an image forming section;
- and
- a sheet removal determination system, comprising:
- a first detection device configured to detect a sheet discharged to a discharge port;
- a second detection device configured to detect a terminal device positioned within a communication enabled range of the second detection device;
- and
- a controller configured to identify a user based on user information acquired from the terminal device detected by the second detection device, determine that the sheet has been removed by the user if, before detection of the terminal device by the second detection device, a first quantity of sheets detected by the first detection device is less than a second quantity of sheets detected by the first detection device.
