Abstract: A save control unit stores document data and manager data associated with each other. A request acquiring unit acquires an output request including: requester data, document designation data, and allowable display time data. An output control unit, when the output request is acquired, and on a condition of fulfilling a user condition and a time condition, executes a document image output process according to receiving of a request from the image display apparatus. The user condition is a condition that the manager data is consistent with the requester data. The time condition is a condition that an elapsed time from a time point when the output request was acquired is within a time shown by the allowable display time data. The document image output process is a process of sending, to the image display apparatus, an output image that is based on the target document data.

Abstract: A bed-leaving prediction device (server device) (10) is connected through a digital communication network (60) to: a portable information processing terminal (40) of care staff; environmental sensors (32 to 34) for detecting environment values such as temperature in a room; a human sensor (31); and a bed sensor (35). A bed-leaving prediction processing section (115) calculates a bed-leaving prediction value indicative of a degree of possibility that a care recipient leaves a sleeping furniture after a second time interval has expired since a current time point based on a plurality of environment values detected in a time period between the current time point and a time point before expiration of a first time interval, outputs of the human sensor, and outputs of the bed sensor.

Abstract: A fixation heater heats a specific part with resistance heating. A temperature sensor detects as a detection temperature a temperature of the specific part. An alternating current switching unit turns on and off alternating current power supply to the fixation heater. A controller controls the alternating current switching unit with a heater control signal and thereby performs temperature control of the fixation heater. An estimation calculating unit derives an estimation temperature at a second time point on the basis of the detection temperature at a first time point and the heater control signal until the second time point, and the second time point is a time point when a predetermined time elapses from the first time point. An anomaly detecting unit detects anomaly on the basis of the detection temperature at the second time point and the estimation temperature at the second time point.

Abstract: An image reading device includes an image reading unit, a conductive member, a switching portion, and a switching control portion. The image reading unit includes a light emitting portion and a light receiving portion. The light emitting portion irradiates light on a document sheet that is conveyed while in contact with an upper surface of a plate-like contact member. The light receiving portion outputs image data corresponding to light reflected from the document sheet. The conductive member is provided on a lower surface of the contact member. The switching portion is switched between an on-state and an off-state so as to select between a state where the conductive member is grounded or a state where the conductive member is not grounded. The switching control portion controls switching of the switching portion.

Abstract: An image forming apparatus includes a heating roller, a temperature sensor, a controller, a signal wire, and a first resistor. The temperature sensor detects the temperature of a heating roller. The controller has a processor. The signal wire transmits a signal of the temperature sensor to the controller (input terminal). The first resistor is disposed between an output terminal of the controller and the signal wire. The controller includes a voltage application unit, a voltage detection unit, and a determination unit. The voltage application unit applies a voltage to the output terminal. The voltage detection unit detects a voltage value of the input terminal. The determination unit determines whether or not an abnormality occurs in the signal wire, on the basis of the voltage value detected by the voltage detection unit.
