An image reading device starts executing a reading process before a sheet reaches a reading position, and executes the reading process subsequently and repeatedly. A partial image is acquired each time the reading process is executed. Each time one partial image is acquired, the image reading device determines a number of pixels awarded to the one partial image; and determines an intensity awarded to the one partial image. The image reading device decides that at least one of the two successively-acquired partial images corresponds to an end of the sheet when the two partial images satisfy the conditions (A) and (B). Condition (A): the determined number of pixels is changed between the two successively-acquired partial images. Condition (B): the determined intensity is changed between the two successively-acquired partial images.

Image reading device for detecting end of sheet

A communication system switches a communication state from a first communication state where a wireless communication unit of a communication device performs data communication and voice communication with an external device and a phone device to a second communication state to perform the data communication between the phone device and the external device, in response to electric power supply to the wireless communication unit being interrupted. The first communication state is set with a communication-device network ID used for the communication device and a phone-device network ID used for the phone device. The second communication state is set with the phone-device network ID used for the communication device and the communication-device network ID used for the phone device.

A communication system switches a communication state from a first communication state where a communication device performs data communication and voice communication with an external device, a first phone device, and a second phone device to a second communication state to perform the voice communication between the communication device and the second phone device and the data communication between the first phone device and the external device, when the voice communication is started using the second phone device in response to a call from a communication line. The second communication state is set when a first-phone-device network ID is used for the communication device, a communication-device network ID is used for the first phone device, and a party device of the second phone device is set to a device identified with the first-phone-device network ID.
