Filed: 1990-04-18
Abstract: PURPOSE:To constitute the electronic apparatus so that a user can continue the same work without executing again the same application processing from an initial state by stopping the control of a main control means in an attaching/ detaching period of an external device, and on the other hand, holding the same output state through before and after the attaching/detaching period of the external device as for an output means. CONSTITUTION:A cover 4a is opened only in an attaching/detaching period of an external device 2, therefore, in a period in which an output signal 21 of a detecting switch 3 is logic '0', a user attaches and detaches the external device 2. A microcomputer 11 sleeps by an interruption caused by a signal 22 in the course of execution of various applications, and also, returns to the application which is being executed. That is, it becomes a sleep state only in a period in which the user attaches and detaches the external device 2, and after the sleep period is finished, the interrupted application is continued from the interrupted part. In such a way, the operation of the power source and the reset processing are not required, and the continuance of the application is not obstructed.
