Description

  The present invention relates to a protective case for a tablet terminal.

  In recent years, tablet devices that are portable and can be operated with a touch panel are commercially available from Apple Inc. and others. Such tablet terminals are used for e-mail transmission / reception and schedule management.

  Tablet devices are often carried around all the time, and the display and back are easily scratched accordingly. In order to protect both the display surface and the back surface of the tablet terminal, the display surface protection part that protects the display surface and the back surface protection part that protects the back surface are connected by a connection part, and the tablet terminal protection of the hard cover shape of the book Some users wish to use a case to reliably protect both the display and back. Such a protective case is normally used by fixing the tablet terminal to the back surface protection unit.

  The viewing angle of a tablet terminal is generally very wide, and when used in a train, the screen can be easily peeped by a person sitting next to it. In order to prevent the screen from being peeped, privacy filters (peep prevention filters) for limiting the viewing angle have been released by various vendors. As a method of attaching the privacy filter to the tablet terminal, there are a method of pasting the privacy filter on the screen, a method of providing attachments at the four corners of the tablet terminal, and fixing the privacy filter using this attachment.

  In addition to personal use, tablet terminals are often used for presentations while showing materials at customers. When using a tablet terminal for such purposes, the privacy filter that limits the viewing angle interferes with the presentation. Therefore, the presentation is performed with the privacy filter removed, and the privacy filter is attached again after completion.

In this way, it is not only troublesome to attach and detach the privacy filter frequently, but the type of filter that sticks to the screen with adhesive or adsorption type becomes sticky or repeatedly attached with attachments as it is repeatedly attached and detached. The attachment part may be damaged during repeated attachment and detachment.
This invention is made | formed in view of such a situation, and provides the protective case for tablet terminals which can change the arrangement | positioning state of a privacy filter easily.

The connecting portion is provided on one side surface of the back protection portion,
A tablet terminal protective case is provided in which a privacy filter holder that can be rotated in the rotating portion is provided on the other side surface of the back surface protecting portion.

  The present inventor has intensively studied to solve the problems caused by repeated attachment and detachment as described above, and the privacy filter only needs to be disposed between the tablet terminal and the observer, and is not necessarily a tablet. I noticed that there was no need to pin it to the terminal. Then, the idea of attaching a privacy filter to the tablet terminal was abandoned and the idea of providing a rotatable privacy filter holder in the protective case was reached.

  The privacy filter holder is provided with a privacy filter. By rotating this holder, the privacy filter is usually placed on the screen to ensure privacy. It can be used such that the privacy filter is not disposed between the screen and the viewer by rotating. According to the present invention, the conventional method is very troublesome because there is a trouble of attaching and removing the privacy filter and a trouble of attaching and removing the privacy filter to the attachment. There is no hassle, and the user can quickly and easily switch between personal use and presentation use simply by rotating the privacy filter holder.
