By the way, while operating OA equipment via a keyboard, the operator often interrupts his work and leaves his desk.

In such cases, for safety reasons, it is necessary to memorize (save) the input information and leave the desk. Some or all of the input information may be altered or erased due to intentional key operations, and if such a situation occurs, it will be a hassle to recall the necessary stored information when continuing to work. It takes.

In particular, if the above-mentioned situation occurs when the user forgets or neglects to perform memory processing, the user will be forced to re-enter the information from the beginning, resulting in a large amount of loss.

As a countermeasure, the keyboard is provided with a cover, and when the operator leaves the seat, the keyboard is covered.

``Problem to be solved by the invention'' Usually, the above-mentioned cover is assembled and integrated with the keyboard.

However, if the cover is integrally assembled with the keyboard, the structure, specifications, etc. of the keyboard must be considerably modified, which increases the difficulty of manufacturing the keyboard itself and increases the cost.

Furthermore, even if it is technically possible to attach a new cover to a ready-made keyboard without a cover, it is currently not practiced because it requires too much effort and expense.

In view of the above-mentioned problems, the present invention aims to provide a simple and inexpensive keyboard cover that does not require modification of the keyboard itself and can be easily applied to a ready-made keyboard.
