a display switching section for switching a display direction of information on the display screen in accordance with a relative position of the pen tip region and the palm region determined by the first determining section.

### Claim 2 (depends on 1)

The input display device as set forth in claim 1, further comprising:
a second determining section for determining whether or not the pen tip region and the palm region are regions in which each of a pen tip input and a palm input is carried out by a same user, in accordance with a distance between the pen tip region and the palm region, the pen tip region and the palm region being determined by the first determining section, and
the display switching section switching the display direction of information on the display screen in accordance with the relative position of the pen tip region and the palm region being determined by the second determining section as being the pen tip region and the palm region of the pen tip input and the palm input carried out by the same user, respectively.

### Claim 3 (depends on 2)

The input display device as set forth in claim 2, further comprising:
a third determining section for determining whether a shape of the palm region out of the pen tip region and the palm region is vertically long or horizontally long, the pen tip region and the palm region being determined by the second determining section as being carried out by the same user, respectively, and
the display switching section switching the display direction of information on the display screen in accordance with (i) the relative position of the pen tip region and the palm region determined by the second determining section as being carried out by the same user and (ii) information indicative of the shape of the palm region determined to be vertically long or horizontally long by the third determining section.

### Claim 4 (depends on 1)

The input display device as set forth in claim 1, further comprising a screen drawing section for displaying a screen in accordance with an input detected by the sensor, and
when the pen tip region has triggered switching-over of the display direction of information by the display switching section, the screen drawing section not recognizing the pen tip region as an input to the screen.

### Claim 5 (depends on 2)

The input display device as set forth in claim 2, wherein, in a case where a plurality of pen tip regions are determined to exist by the first determining section:
the second determining section specifies, for each of the plurality of pen tip regions, a palm region corresponding to the pen tip region in accordance with a relative position of the pen tip region and the palm region, the palm region corresponding to the pen tip region being a palm region in which the palm input can be determined to be carried out by the same user who carries out the pen tip input of the pen tip region; and
the display switching section switches a display direction of information in a display region corresponding to each of the plurality of pen tip regions on the display screen, in accordance with the relative position of the pen tip region and the palm region, the pen tip region and the palm region in which the pen tip input and the palm input are determined, by the second determining section, as being carried out by the same user, respectively.

### Claim 6

A control device of an input display device including (i) a display screen for displaying information and (ii) a sensor for detecting an input to the display screen, and being capable of accepting input with a pen, the control device comprising:
a first determining section for determining whether an input region detected by the sensor is a pen tip region in which an input is carried out with a pen or a palm region in which an input is carried out by touching a hand holding a pen, in accordance with a size of the input region; and
a display switching section for switching a display direction of information on the display screen in accordance with a relative position of the pen tip region and the palm region determined by the first determining section.

### Claim 7 (depends on 6)

The control device of the input display device as set forth in claim 6, further comprising:
a second determining section for determining whether or not the pen tip region and the palm region are regions in which each of a pen tip input and a palm input is carried out by a same user, in accordance with a distance between the pen tip region and the palm region, the pen tip region and the palm region being determined by the first determining section, and
the display switching section switching the display direction of information on the display screen in accordance with the relative position of the pen tip region and the palm region, the pen tip region and the palm region being determined by the second determining section as being the pen tip region and the palm region of the pen tip input and the palm input carried out by the same user, respectively.

### Claim 8 (depends on 7)
