A data communicating device is provided having an actuating means that is driven when data is to be transmitted/received. Prior to transmitting/receiving data, the actuating means is driven and a transmission condition is set in accordance with a determined noise level of the actuating means. The data is then transmitted/received in accordance with the thus set transmission condition.

Data communication device with transmitting condition set in accordance

A facsimile device transmits image data from a calling station to a facsimile device at a called station over a transmission line. The facsimile device has an image reader for reading image data to be transmitted, and a driver including a motor for actuating the image reader to read the image data. When a TCF signal is transmitted from the calling station to the called station to check the condition of the transmission line, a controller energizes the motor, which results in electrical noise being generated, corrupting the TCF signal. The controller then controls a transmission rate at which the image data is to be transmitted depending on the level of electrical noise in the TCF signal, that is detected at the called station. Since the transmission rate is established depending on the level of electrical noise, communication or decoding errors are reduced during the transmission of the image data.

Facsimile device with motor startup during initialization

A thermal printer for printing on a planar recording medium, by heating and thereby coloring a thermally fusible material on the medium. The printer has a thermal print head having heat-generating elements each of which produces heat in contact with the surface of the recording medium, a feeding device for feeding the print head and the recording medium relative to each other, and an anti-sticking device for moving the print head and the recording medium relative to each other, to thereby prevent the print head and the surface of the recording medium from sticking to each other, when the heated thermally fusible material is solidified.
