## Abstract

An object of the present invention is to provide a cellular telephone terminal in which intuitive operation is possible, by providing a rotary dial portion. A cellular telephone terminal is provided with: a body that includes an operation unit side body, a display part side body, and a hinge mechanism that connects the operation unit side body g and the display part side body; a rotary dial portion, which is rotatable around a rotational axis, and which is attached to the body with a standard position; a mark which serves as an indicator for a rotation amount of the rotary dial portion; and a control part that causes one application among a plurality of applications to enter a state in which activation thereof is possible, based on the rotation amount of the rotary dial portion.

## Claims

### Claim 1

A portable electronic apparatus,
comprising: a display part;
a rotary dial portion that is attached to a body so as to be rotatable in a predetermined direction;
a touch sensor that detects contact to the rotary dial portion;
a rotation detecting part that detects rotation of the rotary dial portion; and
a control part that controls such that a predetermined application is selected in accordance with a rotation state detected by the rotation detecting part, and a display screen corresponding to the activated predetermined application is displayed on the display part, wherein the control part controls such that the selected application is activated.
