Abstract: An image forming apparatus includes a sheet storage section, an image forming device, a transport route, a transport device, and a switching device. The switching device is turned on or off depending on a pressing force applied by an end portion of a sheet being transported along the transport route, at a position on the transport route upstream of the image forming device in a sheet transport direction. The switching device is turned on or off depending on whether the pressing force is equal to or larger than a predetermined pressing force to be applied by the sheet having predetermined rigidity, or smaller than the predetermined pressing force.

Abstract: A transmitter transmits ultrasonic wave of a predetermined volume. A reflected ultrasonic wave receiver receives reflected ultrasonic wave, transmitted from the transmitter and reflected by a sheet. A permeated ultrasonic wave receiver receives permeated ultrasonic wave, transmitted by the transmitter and permeated through the sheet. A volume detector detects reflected volume of the reflected ultrasonic wave, and permeated volume of the permeated ultrasonic wave. The decider identifies a thickness of the sheet being transported by a transport device, and decides whether multifeed of the sheets is occurring, on a basis of a comparison result between the detected reflected volume and a reference reflected volume, and a comparison result between the detected permeated volume and a reference permeated volume.

Abstract: An image forming apparatus includes a heater, a temperature sensor, a power supply circuit, a main processor, and a sub-processor. The temperature sensor is configured to detect a temperature of the heater. The power supply circuit is configured to perform power supply to the heater. The main processor is configured to supply a heater control signal to the power supply circuit based on the temperature detected by the temperature sensor to control the power supply circuit and adjust the temperature of the heater. The sub-processor (a) monitors whether or not an output from the main processor is made regularly, and (b) supplies, to the power supply circuit, the heater control signal for cutting off the power supply to the heater when determination is made that the output is not made.

Abstract: A feeding device includes a sheet tray, a transport device, a sheet sensor, and a control device. On the sheet tray, a sheet is placed. The transport device transports the sheet placed on the sheet tray. The sheet sensor is located upstream of the transport device in a sheet transport direction, and outputs curvature information indicating a curvature status of the sheet being transported by the transport device. The control device includes a processor, and acts as a measuring device and a calculation device, when the processor executes a control program. The measuring device measures a curvature amount of the sheet, on a basis of the curvature information. The calculation device calculates rigidity of the sheet, on a basis of the curvature amount.

Abstract: A paper conveyance device includes a paper feed unit, a conveyance rotator, a conveyance guide, a multi-feed detection unit, and a control unit. The control unit causes an ultrasonic sensor to transmit an ultrasonic wave in a detection section. The control unit sets a detection execution section and a detection skip section in the detection section. The control unit does not determine whether multi-feed has occurred in the detection skip section. The control unit sets the detection skip section based on a time point at which vibration is applied to conveyed paper.
