  • Patent number: 9645541
    Abstract: Image forming apparatus comprises an electric power supply circuit board, an electric power control unit, functional circuits, and an electrical power saving circuit. The electric power control unit executes constant voltage control, to make electrical potential of a remote sensing location constant. The functional circuits are connected with the electric power supply circuit board. The electrical power saving circuit switches the state of functional circuits between the state in which they are provided with electric power and the state in which they are not provided with electric power. The electrical power saving circuit sets the contact point of the input side of the circuit, in which the consumption electrical current or the behavior guarantee minimum electrical voltage is the largest, out of the electrical power saving circuit and functional circuits provided with electric power, as the remote sensing location.

  • Patent number: 9586297
    Abstract: A vehicle body component mounting system is provided with, along a conveyance path for a vehicle body, an upstream component mounting work area using a cell production system, a central component mounting work area in which the vehicle body is conveyed by an overhead conveyor, and a downstream component mounting work area using the cell production system in this order. Components other than principal components are mounted to the vehicle body using the cell production system. The cell production system is adaptable by increasing the number of component boxes, and thus an increase in the length of the line is prevented. The increase in the length of the line is prevented by using a line production system as a base and also using the cell production system as a part thereof.

  • Patent number: 9396420
    Abstract: An event detecting unit detects a specific error event or a specific warning event. An event notice transmitting unit transmits an event notice of the detected event to another image forming apparatus. An event notice receiving unit receives an event notice from another image forming apparatus. A status control unit is capable of changing the operation mode among a normal mode and a sleep mode. The status control unit changes the operation mode to the sleep mode or an out-of-service expression mode if the event notice is received in the normal mode. The out-of-service expression mode includes at least one of (a) putting off a light of the display device, (b) stopping a part or all of internal devices that make operation noise sound, and (c) denying reception of an execution request to a part or all of functions.
