    • A mobile device for a vehicle includes a receiving unit that receives transmission signals transmitted from individual transmitting antennas of a vehicle-side device; a control unit that determines distances to the individual transmitting antennas using the signal strengths of the received transmission signals; and a transmitting unit that transmits, to the vehicle-side device using wireless communication, data items indicating the distances. In a time period in which communication is not performed between the mobile device and the vehicle-side device, the signal strength of a received signal is measured, thereby obtaining a measurement value, and the measurement value is stored as a noise element in a memory. When communication between the mobile device and the vehicle-side device is performed, correction for noise is performed on the signal strengths of the transmission signals transmitted from the transmitting antennas, and the distances are determined.

    • A thermal printer 1 and control method for controlling print speed to prevent variation in printing pitch due to frequent slight changes in the print speed following a significant change in print speed. The print speed, which is the speed at which the print medium i.e., paper is conveyed when printing, is controlled based on known print speed control factors. The thermal printer comprises a paper feed mechanism for conveying the print medium at a controlled print speed passed a thermal print head, a print speed control unit 9 for controlling the print speed of the paper feed mechanism based on the print speed control factors, a print speed change acquisition unit 3 for determining the change in the print speed over a predetermined time, and a comparison unit 7 for determining if the change in print speed exceeds a predetermined threshold value. The print speed control unit 9 limits change in the print speed based on the print speed control factors for a predetermined time after the comparison unit 7 determines that the change in print speed exceeds the threshold value.
