Abstract: An image forming device includes first and second discharge rollers, and first and second covers. The first cover is pivotally movable between first closing and opening positions about a first pivot axis. In the first opening position, the first cover supports a sheet from the first discharge roller. The second cover is pivotally movable between second closing and opening positions about a second pivot axis. In the second opening position, the second cover guides a sheet from the second discharge roller. In the first closing position, one end portion of the first cover is farther from the second cover. In the second closing position, another end portion of the second cover is farther from the first cover. The first pivot axis is at the one end portion of the first cover. The second pivot axis is at the another end portion of the second cover.

Abstract: To provide a vehicle electronic control unit including a first microcomputer (2, 3) and a second microcomputer (3, 2) capable of transmitting and receiving signals to and from the first microcomputer. One of the first microcomputer and the second microcomputer outputs a PWM signal to the other microcomputer (3, 2). The other microcomputer detects an on-time of the PWM signal, performs a self diagnosis according to the detected on-time, and outputs a self diagnosis result to the one microcomputer. The one microcomputer diagnoses the other microcomputer based on the self diagnosis result.
