Abstract: A stop control system for a vehicle is provided, which is capable of stably performing cranking for restarting an internal combustion engine and positively preventing the vehicle from moving by properly increasing a braking force of the vehicle, during an idle stop. In the stop control system for a vehicle according to the present invention, the engine 3 is cranked by the starter motor 6 using the power supplied from the battery 7, when restart conditions are satisfied (step 8 in FIG. 5). Further, the stop control system includes a hydraulic pump 55 driven by the power supplied from the battery 7, for increasing the braking force of the vehicle V. During a stop of the vehicle V, it is determined whether or not the braking force of the vehicle V needs to be increased (FIG. 6), and the hydraulic pump 55 is controlled according to a determination result.

During a stop of the vehicle V, when it is determined that the braking force of the vehicle V needs to be increased (F_BFREQ=1), the hydraulic pump 55 is activated. Further, if the restart conditions are satisfied during operation of the hydraulic pump 55, the cranking is inhibited to continue the operation of the hydraulic pump 55 (steps 6 to 9 in FIG. 5).

Abstract: An image reading apparatus used for an image forming apparatus that is coupled therewith and that has a main controller which performs control of the image forming apparatus includes an image reading unit, a detector, and a communication controller. The image reading unit reads an image formed on a document. The detector detects a state of the image reading unit. The communication controller connects to the main controller, the detector, and a communication line. Power is supplied to the detector and the communication controller in both a first operating state, in which supply of power to the main controller is stopped, and a second operating state, in which power is supplied to the main controller. The detector transmits a detection signal to the communication controller in the first operating state, and transmits the detection signal to the main controller in the second operating state.

Abstract: An image reading apparatus includes a body; a circuit board fixed to the body; a light emitter disposed on a first surface of the circuit board, the light emitter emitting light with which a document is irradiated; a light guide disposed opposite the circuit board with the light emitter therebetween, the light emitted from the light emitter passing through the light guide; an urging unit; a supporting unit fixed to the body; and a pressing unit. The pressing unit includes a first portion and a second portion. The first portion is pressed in a direction from the light emitter toward the light guide as a result of receiving a force from the urging unit. The second portion presses the light guide against the light emitter as a result of receiving a reaction force from the supporting unit when the first portion is pressed.
