8. The information processing apparatus of claim 1 , wherein the processor is configured to output a command controlling the projection device to stop projecting the image when an output of the first detector indicates that the member has changed from the closed state to the open state.
9. The information processing apparatus of claim 1 , wherein the processor outputs a command controlling the projection device to project an image when an output of the first detector indicates that the member is in the open state and an output of the second detector indicates that the main body is connected to the cradle.
10. The information processing apparatus of claim 9 , wherein the processor is configured to output a command controlling the projection device to stop projecting the image when an output of the first detector indicates that the member has changed from the open state to the closed state with respect to the main body.
11. An information processing apparatus comprising:
a main body;
a member movably attached in an least first and second axial directions with respect to the main body;
a first detector configured to detect an orientation of the member with respect to the main body;

the first detector is configured to detect whether the surface of the member including the display is facing inward or outward with respect to the main body in relation to the second axial direction, and
the processor outputs a command controlling the projection device to project an image when an output of the first detector indicates that the member is in the open state and the display is facing inward and an output of the second detector indicates that the main body is connected to the cradle.
12. The information processing apparatus of claim 6 , further comprising:
an interface configured to connect to the cradle apparatus, wherein the interface is configured to receive an identification corresponding to the cradle apparatus upon being connected to the cradle apparatus.
13. The information processing apparatus of claim 12 , further comprising:
a memory configured to store projection start conditions indicating an orientation of the touch-panel interface with respect to the main body to initiate a projection operation.
14. The information processing apparatus of claim 13 , wherein the processor is configured to control the touch-panel interface to display information corresponding to the projection start conditions.
15. The information processing apparatus of claim 6 , wherein the processor is configured to control the projection device to display information displayed on the touch-panel interface or information different from that displayed on the touch panel interface.
16. An information processing method performed by an information processing apparatus, the method comprising:
detecting, by a first detector of the information processing apparatus, an orientation of a member movably attached in an least first and second axial directions with respect to a main body of the information processing apparatus with respect to the main body;
detecting, by a second detector of the information processing apparatus, whether the main body is connected to a cradle apparatus; and
controlling, by a processor of the information processing apparatus, an operation of a projection device based on an output of the first and second detectors, wherein
