Abstract: A USB device comprises a USB connector 1 for connecting it to a USB or HUB of a host and a serial interface engine (SIE) 2 serving as an interface. The USB connector 1 and the SIE 2 are interconnected by four signal lines defined in a USB. Of these signal lines, a 5-V power supply line for supplying 5-V power to the SIE 2 is provided with a switch 3 for electrically on-off switching it. The user can readily control the power supply from the host to the USB switch by operating the switch. Thus, when the USB device is not used, the power supply from the host can be stopped to reduce power consumption of the host.

Abstract: When the scanner moves over the subject copy, the first reading elements of a close contact type image sensor (1) read the copy. As the movement causes a platen roller (5) to rotate, an encoder ring (4), having a prescribed distinguishing pattern (10) printed within, rotates. Second reading elements configured outside the copy reading range of the close contact type image sensor (1) read the distinguishing pattern, which moves over the reading face as the encoder ring (4) rotates. The second reading elements which read the distinguishing pattern are driven independently of the first reading elements for reading the subject copy, and their reading period is shorter than that of the first reading elements. This configuration enables the moving speed to be accurately detected even when the scanner moves faster than the copy reading speed.

Abstract: An image reading device, particularly a hand scanner, capable of setting a reading position in the main scanning direction accurately at all times. A stage glass is affixed to the reading surface of the hand scanner. A reference line is printed on the stage glass outside of the valid reading range of a CCD (Charge Coupled Device) image scanner. For the adjustment of the valid reading range, the image sensor and a lens are roughly adjusted such that data representative of the reference line appears at the edge of the valid reading range. Subsequently, the valid reading range is electrically shifted in the main scanning direction such that the reference line disappears.
