摘要 PURPOSE:To switch the acting state of the device without setting time. CONSTITUTION:When the brightness of the external of the device is equal to or below a fixed value, an environment detecting CPU 62 decides that external environment is 'dark', and sets a 'sleepe state' where a normal feed part 32 is turned off and only an environmental change detection part 29 acts through the on/sleep switching signal line 37. On the other hand, when the brightness of the external becomes equal to or above the fixed value, the CPU 62 decides that the external environment is 'bright' and sets the feed part 32 to be on through the on/sleep switching signal line 37. Thus, the device gets in an ordinary use state and the main body 1 performs printing processing.
