1. An image forming apparatus comprising:
- a data storing section;
a detection section configured to detect a presence or an absence of an enabler key insertable in and removable from the apparatus; and
a control section configured to overwrite new data, to be stored in the data storing section, on existing data in the data storing section and to store the new data therein when a result of a detection by the detection section indicates presence of the enabler key, to store new data in the data storing section without overwriting the new data on existing data in the data storing section when the result of the detection by the detection section indicates absence of the enabler key continuously from a startup of the apparatus, and to stop the apparatus when the result of the detection by the detection section changes from presence of the enabler key to absence of the enabler key after startup of the apparatus.

Abstract
When an enabler key 10 is inserted in the main body 1, an overwrite mode for overwriting new data on existing data in a hard disk drive 25 is set. When the enabler key 10 is removed from the main body 1, the overwrite mode is released. During startup of the main body 1 and at every fixed time t1 after the startup of the main body 1, presence or absence of insertion of the enabler key 10 is detected. When a result of this detection changes from “present” to “absent”, the main body 1 is stopped.

8. A control method of an image forming apparatus including a data storing section, the control method comprising:
-
detecting presence or absence of an enabler key insertable in and removable from the apparatus; and overwriting new data, to be stored in the data storing section, on existing data in the data storing section and storing the data therein when a result of detecting indicates presence of the enabler key, storing new data in the data storing section without overwriting the new data on existing data in the data storing section when the result of detecting indicates absence of the enabler key continuously from startup of the apparatus, and stopping the apparatus when the result of detecting is a change from presence of the enabler key to absence of the enabler key after startup of the apparatus. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An image forming apparatus comprising:
-
data storing means for storing data; detecting means for detecting presence or absence of an enabler key insertable in and removable from the apparatus; and controlling means for overwriting new data, to be stored in the data storing means, on existing data in the data storing means and storing the new data therein when a result of detection by the detecting means indicates presence of the enabler key, for storing the new data in the data storing means without overwriting the new data on existing data in the data storing means when the result of detection by the detecting means indicates absence of the enabler key continuously from startup of the apparatus, and for stopping the apparatus when the result of detection by the detecting means changes from presence of the enabler key to absence of the enabler key after startup of the apparatus. - View Dependent Claims (16, 17, 18, 19, 20)
