Abstract: An image forming system includes an image forming apparatus which can wirelessly transmit information that there is a waiting job and has a plurality of modes concerning power consumption, a portable terminal which can receive the information transmitted from the image forming apparatus, a position detector which detects a position of the portable terminal, and a mode switcher which switches from one mode concerning power consumption of the image forming apparatus to another in accordance with the position of the portable terminal which received the information. The position detector detects the distance between a user carrying the portable terminal and the image forming apparatus. Based on the distance data at the time when the portable terminal received the information that there is a document waiting for being outputted by the image forming apparatus, the mode concerning power consumption of the image forming apparatus is switched by the mode switcher.

Abstract: A drive control mechanism for an image reader having a controller, to control a drive current impressed to a connected stepping motor such that the impression of the drive current is carried out in a prescribed number of steps, and a changer, to change a largest value of a drive current in response to a scanning speed of a reading device of the image reader. Consequently, smooth rotation with little torque ripple may be obtained through microstep driving, and by changing a largest drive current, control of a drive torque becomes easier, thus making it possible to maintain an even balance between load torque and drive vibration when a high-torque motor is used to eliminate slider vibration.

Abstract: According to the invention, when directed to slow down a driven device, the speed of a driving motor is reduced from a first speed to a slower second speed. In this state, a driving gear continues to rotate at said second speed, whereas a driven gear continues to rotate by inertia and gradually slows down from said first speed. Thus, the rear of a cog of the driven gear is separated from the front of a cog of the driving gear. When the speed of the driven gear is equal to the second speed, i.e., the speed of the driving gear, the front of another cog of the driven gear reaches the rear of said cog of the driving gear. Accordingly, both gears lightly make contact. Thereafter, the driving motor is rapidly braked by maintaining the contact of the driving gear and driven gear such that both gears slow down and stop.When slowing down a driven device, noise generated by the impact of both gears is reduced as much as possible, and the time for slowing down a driven device is reduced.
