Projector unit for portable information devices
A portable information device having a projector unit is disclosed. The projector unit includes a chassis, a connection terminal part and a projector part. The chassis includes an attachment part removably attached to an attachment target part disposed on a side surface of the portable information device. The connection terminal part is electrically connected to a terminal of the portable information device when the attachment part is attached to the attachment target part. The projector part is rotatably attached to the chassis so that a direction of projection from a projector lens can be changed.
1. A projector unit comprising:
a substantially cylindrical chassis having an attachment part removably attached to an attachment target part disposed on a first edge of a portable information device;
a connection terminal part electrically connects to a terminal of said portable information device when said attachment part is physically attached to said attachment target part; and
a projector part locates on a cylindrical surface of said substantially cylindrical chassis to allow a projection direction from a projector lens to be changeable, wherein said projector lens is to be housed in said chassis by rotating said projector part with respect to said chassis.
2. The projector unit of claim 1 , wherein said chassis has a rod shape with a longitudinal axis extending along said first edge of said portable information device.
3. The projector unit of claim 1 , wherein said attachment part is disposed on a surface of said chassis.
4. The projector unit of claim 1 , wherein said projector part is disposed on a surface of said chassis opposite to the surface on which said attachment part is disposed.
5. The projector unit of claim 1 , wherein, said chassis thither includes an adjustment button for adjusting a shape of a projected video image.
6. The projector unit of claim 1 , wherein said chassis further includes a battery.
7. The projector unit of claim 6 , wherein power consumption of said battery is reduced when said projector unit uses power from a power supply of said portable information device without using said battery even when said battery is provided.
8. A projector unit comprising:
a substantially cylindrical chassis having an attachment part removably attached to an attachment target part disposed on a first edge of a portable information device;
a connection terminal part electrically connects to a terminal of said portable information device when said attachment part is physically attached to said attachment target part; and
a projector part locates on a cylindrical surface of said substantially cylindrical chassis to allow a projection direction from a projector lens to be changeable, wherein a rotation shaft of said projector part around which said projector part rotates with respect to said chassis extends along a longitudinal axis of said chassis along said first edge of said portable information device.
9. An electronic device comprising:
a portable information device; and
a projector unit removably attached to said portable information, device, wherein said projector unit includes
a substantially cylindrical chassis having an attachment part removably attached to an attachment target part disposed on a first edge of said portable information device;
a connection terminal part electrically connects to a terminal of said portable information device when said attachment part is physically attached to said attachment target part; and
a projector part locates on a cylindrical surface of said substantially cylindrical chassis to allow a projection direction from a projector lens to be changeable, wherein said projector lens is to be housed in said chassis by rotating said projector part with respect to said chassis.
10. The electronic device of claim 9 , herein said chassis has a rod shape with a longitudinal axis extending along said first edge of said portable information device.
11. The electronic device of claim 9 , wherein said attachment part is disposed on a surface of said chassis.
12. The electronic device of claim 9 , wherein said projector part is disposed on a surface of said chassis opposite to the surface on which said attachment part is disposed.
13. The electronic device of claim 9 , wherein a rotation shaft of said projector part around which said projector part rotates with respect to said chassis extends along a longitudinal axis of said chassis along said first edge of said portable information device.
14. The electronic device of claim 9 , wherein said chassis further includes a second edge shorter than said first edge.
15. The electronic device of claim 9 , wherein said chassis further includes an adjustment button for adjusting a shape of a projected video image.
16. The electronic device of claim 9 , wherein said chassis further includes a battery.
17. The electronic device of claim 16 , wherein power consumption of said battery is reduced when said projector unit uses power from a power supply of said portable information device without using said battery even when said battery is provided.
18. The electronic device of claim 9 , wherein said chassis further includes a second edge shorter than said first edge.
