Portable electronic device with a projector

摘要

An object of the present invention is to provide a portable electronic device which the user can comfortably use by suppressing temperature rise in the surface of the device caused by heat from a heat source. The object is achieved by a portable electronic device including: a first casing; a second casing disposed opposed to one of surfaces of the first casing and capable of changing a position relative to the first casing while maintaining a state where opposed surfaces are opposed; and a heat source disposed in the second casing. Surface of the second casing includes: a first region which is covered with the first casing in a first state where the first and the second casings are opposed and is exposed to the outside in a second state where the position relative to the first casing is changed and area of the opposed surfaces of the first and the second casings decreases from the first state; and a second region which is always exposed to the outside in both of the first and the second states. At least a part of the heat source is disposed in a position corresponding to the first region.

1. A portable electronic device comprising:
a first casing; a second casing disposed opposed to one of the surfaces of the first casing and capable of changing a position relative to the first casing while maintaining a state where opposed surfaces are opposed; a heat source and a heat insulation sheet disposed in the second casing; and a display arranged on the second casing, wherein the heat insulation sheet is interposed between a surface of the display and the heat source; wherein the surfaces of the second casing include
a first region which overlaps with the first casing in a first state where the first and the second casings are opposed and is exposed to the outside in a second state where the position relative to the first casing is changed and an overlapping area of the opposed surfaces of the first and the second casings decreases from the first state, anda second region which is always exposed to the outside in both of the first and the second states, at least a part of the heat source is disposed in a position corresponding to the first region, and the second casing includes a fan, an eccentric weight and a vibration motor having a rotary shaft and a one-way clutch interposed between the rotary shaft and the eccentric weight such that, at the time of rotation in one direction, the vibration motor generates vibrations by rotating the eccentric weight, and at the time of rotation in another direction, the vibration motor rotates only the fan.
