Abstract

PURPOSE:To execute the analysis of key input information as necessary, and to substitute a key input processing for a key input reading processing as necessary by storing data inputted from a main body to an outside attachable and detachable storage medium as the key input information. CONSTITUTION:When a data writing instruction to an IC memory card 30A is inputted from an outside, for example, a DIP switch 50, a CPU 10 transfers a prescribed key code inputted from a keyboard inputting device 40 to the IC memory card 30A and an RAM 60. Therefore, key code input history information inputted from a key inputting means can collected in a prescribed timing. Also, when a data reading instruction to the IC memory card 30A is inputted from the DIP switch 50, the CPU 10 processes the data read from the IC memory card 30A as the key code instead of the prescribed key code inputted from the keyboard inputting device 40.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus capable of recording key input data in a removable storage medium at an arbitrary timing and referring to the key input data recorded in the storage medium at any time.

[0002]

2. Description of the Related Art Conventionally, when various programs (software resources) activated by this type of information processing apparatus are executed, a bug may occur due to a key input operation from a keyboard. When such a situation occurs, the operator cannot clarify when, where, what procedure and what was input. In addition, bugs often occurred when randomly inputting keys from the keyboard. In other words, it is important to clarify which key code occurs in what order.

Conventionally, when such a situation occurs, it is necessary to analyze a key input using a dedicated hardware device (for example, ICE device).

In addition, an operator is required when demonstrating software or teaching operation in this type of information processing apparatus. For example, as in the case of a demonstration, a series of operations are often repeated, and therefore, it is very wasteful to arrange an operator to operate a plurality of information processing devices at the same time.

Further, in preparation for the above situation, special software is prepared, a series of operations is filed in advance, and the software desired to execute the demonstration reads the key data from the file and makes a pseudo key input. It is also possible to execute an operation.

[0006]

Since the conventional information processing apparatus is configured as described above, if a bug occurs during the execution of a program activated on the information processing apparatus, the large-scale processing as described above is performed. Bringing in an ICE device is virtually difficult and some improvement was desired.

In order to execute a demo without relying on an operator for software demonstration, special software is prepared as described above, and in order to file a series of operations in advance, a demo software is designed. It is necessary to develop the function from the stage, and there are problems that the program design load of software becomes heavy and the program size becomes large. Furthermore, in the case of software resources that are difficult to handle such software processing, there is also a problem in operation such that an operator is always required when demonstrating the software.

The present invention has been made to solve the above-mentioned problems, and by storing the data input from the main body as a key input information to a removable external storage medium, the key input information can be obtained at any time. It is an object of the present invention to provide an information processing apparatus capable of performing the analysis of 1. and substituting the key input reading process with the key input reading process at any time.

[0009]

An information processing apparatus according to the present invention includes a storage medium which is detachably attached to a main body, key input means for inputting a predetermined key code, and a predetermined key input from the key input means. It has a buffer for storing a code and a transfer means for transferring a predetermined key code input from the key input means to the storage medium and the buffer based on an externally input data writing instruction to the storage medium.

Further, a removable storage medium in the main body, a key input means for inputting a predetermined key code, and a predetermined key code input from the key input means based on a data read instruction to the externally input storage medium. Instead, it has a control means for performing a key input process based on the data read from the storage medium.

[0011]

According to the present invention, when a data write instruction to the storage medium is input from the outside, the transfer means transfers a predetermined key code input from the key input means to both the storage medium and the buffer. The key code input history information input from the key input means can be collected at a timing.

Further, when a data read instruction for the storage medium is inputted from the outside, the control means processes the data read from the storage medium as the key code instead of the predetermined key code inputted from the key input means. The key input process can be replaced with the key input read process at any time.
