An example image forming apparatus includes a toner cartridge movable to a mounting position in which the toner cartridge is mounted to a mounting portion and a click position further proceeded from the mounting position in a mounting direction; an elastic member to apply elastic force to the toner cartridge in a direction returning from the click position to the mounting position; a locking member to selectively allow removal of the toner cartridge from the mounting portion in accordance with a click operation by which the toner cartridge is moved to the click position and the mounting position; and a click restricting member to selectively allow movement of the toner cartridge from the mounting position to the click position.

Unlocking toner cartridge by click operation

An example connection structure to couple with a toner cartridge includes a connector to be located at a driving position to contact a coupler provided in a toner cartridge, or a tilting position to be tilt with respect to the driving position, and a position maintaining portion to maintain the connector at the tilting position when the connector is separate from the coupler. The connector located at the tilting position is tilted toward a direction opposite to a direction in which the coupler moves when making contact with the connector.

Connection structure for coupling with toner cartridge

An example connection structure includes a connector and a connector support body. The connector is to engage with a coupler of a toner cartridge at a driving position when the toner cartridge is located at an operable position. The connector support body is rotatable about a rotation axis. The connector is also to support the connector to allow the connector to be inclined toward one side or another side with respect to the rotation axis while moving along the rotation axis with respect to the driving position.

The present disclosure provides a wheel speed sensor interface circuit, an operation method thereof, and an electronic control system, the wheel speed sensor interface circuit comprising: a first signal processing unit for receiving a first current signal sensed by a high side of a wheel speed sensor and processing the first current signal to output a first voltage signal; a second signal processing unit for receiving a second current signal sensed by a low side of the wheel speed sensor and processing the second current signal to output a second voltage signal; and a verification unit for comparing the first voltage signal and the second voltage signal with each other and verifying whether the first voltage signal and the second voltage signal are normal. According to the present disclosure, reliability and redundancy for a process of transmitting wheel speed information can be secured.
