It is becoming possible to realize the user's desire to selectively execute multiple application programs by loading them in advance.

However, in conventional configurations, cumbersome key operations are required to select and execute one of multiple loaded application programs, so it is possible to erase programs and data, especially in management mode. Therefore, there is a serious problem in that accumulated valuable information may be altered or lost due to operator error, which may seriously affect subsequent data processing.

In this way, in a system where program selection is enabled only in management mode, even if it becomes possible to keep multiple application programs loaded due to an increase in memory capacity, the operations associated with processing these programs There are problems in that the risks increase and it is difficult to use multiple application programs effectively.

This invention was made in order to solve the above problems. Each application program of a plurality of application programs stored in memory is assigned to a specific key on the terminal, and when the power is turned on, each application program is It is an object of the present invention to provide a terminal device that can select and start each application program with a simple operation by executing each desired application program from the pressed state of a key.

(Means for Solving the Problems) A terminal device according to the present invention is provided with a correspondence table unit in the memory that stores correspondence key information for instructing the execution of each application program stored in the memory, The apparatus is provided with activation control means for comparing selected key information with corresponding key information and controlling selective activation of a specific application program stored in the memory.

(Function) In this invention, when a key input from the key input means is accepted when the power is turned on, the activation control means compares the key information input when the power is turned on with the corresponding key information, and stores the specific application from the memory. Allows you to select a program and start launching a specific application program.
