<p>PROBLEM TO BE SOLVED: To provide the data processor having the data security protection function. SOLUTION: This data processor has the security protection function of data read from a data storage device 22 provided with a connection part 4 which is detachably connected to a connection connector 3 having preliminarily determined prescribed standards, a memory part 5 where data is stored, and a control part 6 which receives the control signal supplied from a data processor main body 2 to control the operation or the memory part 5. The connection connector means 4 of the specific data processor main body has a connector terminal 43 which outputs a discrimination signal AE. The specific data storage device 22 detects the discrimination signal AE outputted from a discrimination signal detection circuit 24, which detects the discrimination signal AE, to open a gate circuit, and the control signal is allowed to pass to the control part 6.</p> |
