To provide a portable terminal having high operability by allowing a user to intuitively easily understand a binding position, and a program readable by a computer of such a portable terminal.

In a cellular phone 10 provided with a panel 22 partitioned by four sides, and a sensor for outputting sensor data based on approach and contact, or the like of an input medium to/with the panel 22, a binding direction during printing of an image 100 displayed in the panel 22 is set on the basis of the sensor data outputted by the sensor. Concretely, the direction (direction directed by an arrow 106) of a flick operation by a user is set as a binding direction. Thus, the user can intuitively set a binding position, so that the operability of the portable terminal can be improved.
