Conventionally, various applications are used in smart phones, and remote control applications of TVs are also appearing.

Each button signal of the remote control is generated on the smartphone and emitted through a separate infrared module.

When a button signal is designated as a predetermined signal, the button is pressed on the touch screen to emit a signal.

Whether or not the remote control is lost or lost, it is convenient to run only the smartphone application.

However, the application for the remote control must be installed separately, and the remote control application must be found and executed. Also, when the screen is turned off according to the screen brightness control, it is necessary to turn on the screen again to execute the remote control. In addition, when the remote control application is running, the remote control application enters standby mode in the background mode when a call comes in, a text message or an SNS message is received.

In other words, the remote control application should be convenient for the user to press the button at any time when necessary, and in many cases, the smartphone having so many uses and frequency of use often requires too many touches and manipulations.

For example, when you run a remote control application for volume up / down and press the button, and then try to change the channel again, you may need to turn the screen back on, run the background mode remote control application again and press the corresponding button. It is an inconvenient operation compared to simple function implementation. In fact, there is a problem that remote control applications are not very useful.

Meanwhile, in order to prevent scratches or damage to the smartphone, various types of cases are conventionally used.

Recently, wallet-type smartphone cases are widely used. The wallet-type smartphone case is configured so that the smartphone can be fixed on the back side of both sides, and the front side can be opened and closed.

If you want to use a remote control application with a smartphone with a wallet-type smartphone case, it is inconvenient to open and close the front cover.

On the other hand, the conventional wallet-type smartphone case has no additional use except for the purpose of storing and storing a credit card as a wallet.

However, if the above-described remote control function is implemented in a smartphone case, it can be a more convenient and user-oriented device.

As an example of such a device, the prior art patent application entitled " a wallet-type smartphone case having a remote control function ", filed on March 5, 2013 and entitled "Patent No. 10-1358681 "By implementing the remote control function of the TV receiver using the button module on the front face of the wallet type smartphone case and the infrared module mounted on the earphone hole of the smartphone, A wallet type smartphone case provided with a remote control function capable of remote control ".
