Abstract: An image forming apparatus includes an image forming device, a transport belt, an optical sensor, an ultrasonic sensor, and a controller. The transport belt transports the recording sheet. The optical sensor emits light to the transport belt, and receives the light reflected by the transport belt. The ultrasonic sensor transmits ultrasonic wave to the transport belt, and receives the ultrasonic wave transmitted through the transport belt. The controller decides whether an output from each of the optical sensor and the ultrasonic sensor represents a normal value or an abnormal value, and executes predetermined control, depending on a combination of decision results about the respective outputs from the optical sensor and the ultrasonic sensor.

Abstract: A torque transmission mechanism includes a cam member which is rotatably supported and is provided with a cam for pressing a joint member in an axial direction of a rotation shaft and a bush which is fitted to the cam member. The bush has an engagement surface with which the cam of the cam member engages. Above mechanism rotates the cam member and moves the cam member along the bush, thereby moving the joint member between an advanced position in which the torque of a drive source is transmitted to a rotary member and a retracted position in which the transmission of the torque of the drive source to the rotary member is released. A rib to which the bush is fitted is formed on an end surface of the cam member existing at a side at which the cam member is fitted to the bush.

Abstract: An electronic apparatus includes a drive roller, a contamination detection device that detects a degree of uncontaminatedness of a surface of the drive roller, a drive motor, a controller, and a display device. The controller executes a first feedback control, when the degree of uncontaminatedness is equal to or higher than a first threshold, executes a second feedback control including increasing the driving force to the drive motor, and displays a first screen announcing necessity to prepare for restoration of the drive roller on the display device, when the degree of uncontaminatedness is lower than the first threshold, and equal to or higher than a second threshold lower than the first threshold, and restricts the drive roller from rotating, and displays a second screen requesting restoration of the drive roller on the display device, when the degree of uncontaminatedness is lower than the second threshold.

Abstract: An image forming apparatus includes a recording head, a cap, a tank, a pump, a third communication pipe and a controller. The cap forms a sealed space including an ejection port of the recording head. The tank is connected to the sealed space through a first communication pipe and generates a humidified air. The pump feeds the humidified air to the sealed space through the first communication pipe. The third communication pipe connects the pump and the sealed space. The controller is performable a capping operation to feed the humidified air to the sealed space and a long-period leaving operation to feed the humidifying liquid in the tank to the sealed space through the third communication pipe and to stop a driving of the pump after a predetermined amount of the humidifying liquid is fed in the sealed space.
