PURPOSE:To prevent a power switch from being turned off by erroneous operation at the time of data transmission to and reception from a higher-order machine. CONSTITUTION:When the extinction operation mode is set by an operation mode setting means, data input from input devices 6 and 10 is inhibited by an extinguishing operation means and light emitting parts 7, 9, and 10 are extinguished, and a data transmission/reception instruction from a higher-order machine 13 is accepted in this state. Thus, the power switch of the device is apparently turned off, and the unexpected accident that the power switch is turned off during data transmission to and reception from the higher-order machine 13 is prevented. |
