Information such as contents and advertisements stored in the memory can be updated by the communication device 202.

  FIG. 9 shows an example of the displayed image. There are three types of image display modes. In the “standby mode”, advertisement information is switched and displayed on the screen every preset time. In the “content selection mode”, content titles are displayed on a screen in a plurality of lines, and a cursor indicating the current content selection status is displayed. In the “content display mode”, content information and advertisement information selected by the user are displayed alternately.

  Switching between these modes is instructed by the CPU 204. The CPU 204 determines an instruction by an operation algorithm programmed so as to make a determination based on the state of the switch 604 that is turned ON / OFF in conjunction with the button 603.

FIG. 10 is a flowchart showing an operation algorithm. Maintaining a standby mode when in the standby mode switch is turned ON less than ₁ second OFF or t. When the switch remains ON for t1 seconds or more, the content selection mode is switched.

In the content selection mode is broken up into multiple lines content title on the screen as shown in FIG. 9, the switch moves the cursor indicating the selection status of the content in the case of t ON less than _one second of the following The content title is selected. The user repeats this operation a plurality of times and moves the cursor to the desired content title.

When you turn ON the switch t more than _one second in the state in which the cursor indicates the content title favorite, the screen is determined in its content is switched to the content display mode.

On the other hand, if the OFF state continues for t ₂ seconds or more, it is determined that the user has left the strap and the screen is returned to the standby mode.

In the content display mode, when the switch is in the ON state, the content screen and the advertisement screen are sequentially displayed, and when the content becomes the last page, the mode is switched to the standby mode.

Here again, as in the other modes, if the OFF state continues for t ₂ seconds or more, it is determined that the user has left the strap and the screen is returned to the standby mode.

  With the above algorithm, the user can select, determine, and browse content by creating a state in which a load is applied to the strap handle (ON) and a state in which no load is applied (OFF).
