Description

  The present invention relates to a portable information processing apparatus having a projector function.

  Generally, a liquid crystal display panel (LCD) is used as a display function configured integrally with the information processing apparatus. Since the LCD is smaller in depth and consumes less power than a cathode ray tube having the same screen size, the information processing apparatus is reduced in size and power consumption.

  However, when manufacturing an LCD, a large amount of carbon dioxide is emitted. For example, when a general notebook personal computer is manufactured, 120 kg of carbon dioxide is emitted per unit, and the amount of carbon dioxide emitted by the manufacture of the LCD occupies about 80 kg.

  Patent Document 1 discloses using a projector as a display function configured integrally with an information processing apparatus. A projector, particularly a projector of a size that can be built into a general notebook personal computer that uses a semiconductor element such as a light emitting diode or a semiconductor laser as a light source, emits a very small amount of carbon dioxide during production compared to an LCD. Further, since a projector using a semiconductor element as a light source consumes less power than an LCD, it can be said that it is preferable from the viewpoint of environmental load over an LCD throughout the product life cycle.

Japanese Patent Laid-Open No. 10-69328

  The information processing apparatus disclosed in Patent Document 1 is configured to have a projector on the back surface. However, since it also has an LCD at the same time, carbon dioxide emissions from manufacturing have not decreased, but rather increased. Further, in this configuration, it is necessary to separately prepare a projection plane on which the projector should project the screen. That is, a projection surface and a fixing member are prepared separately from the information processing apparatus, and are installed before use or projected onto a wall surface or the like.

  Carrying and installing the projection surface and the fixing member separately from the information processing apparatus has a problem that it is inconvenient for the user. Further, there is a problem that the use place is limited because there is no installation place of the projection plane around the use place of the information processing apparatus, and projection is impossible. On the other hand, the projection on the wall surface etc. is not sure whether there is a wall surface etc. at an appropriate position around the place where the information processing device is used, and even if it is, the surface may not be suitable for projection. There is a problem of being restricted.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a portable information processing apparatus in which a projector and a display surface are physically connected and can be stored compactly.

  ADVANTAGE OF THE INVENTION According to this invention, the portable information processing apparatus which connects a projector and a display surface physically and can be accommodated compactly can be provided.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings. The portable information processing apparatus according to the first embodiment of the present invention may be in a folded state, a state where the screen is raised so as to be able to project, and a state where the screen which is raised so as to be able to project is further lifted upward. it can.

  FIG. 1 is a diagram illustrating a state in which the portable information processing apparatus according to the first embodiment of the present invention is folded. 1 includes a top view (a), a back view (b), a front view (c), a left side view (d), and a right side view (e). Referring to FIG. 1, the portable information processing apparatus according to the first embodiment of the present invention has a main body 10 and a screen 13. The main body 10 includes at least input means such as a keyboard and a pointing device and calculation means such as a microprocessor, and is configured to project the calculation result of the calculation means onto the screen 13 by a projector.

  The main body 10 and the screen 13 are connected by the first connecting portions 11a and 11b and the second connecting portions 12a and 12b. As the screen 13, a transmissive screen having a property of transmitting light projected from the rear to the front can be used. The first connection portions 11a and 11b and the second connection portions 12a and 12b can be configured by hinges or the like. In the folded state, the projector cannot project onto the screen 13.

  FIG. 2 is a diagram illustrating a state in which the screen of the portable information processing apparatus according to the first embodiment of the present invention is raised so as to be projected. FIG. 2 includes a top view (a) and a right side view (b). The screen 13 is supported above the main body 10 by the second connection parts 12a and 12b. The projector 14 projects the calculation result on the screen 10.

  FIG. 3 is a diagram illustrating a state in which the screen of the portable information processing apparatus according to the first embodiment of the present invention is lifted further upward from a state where the screen is raised to be able to project. FIG. 3 includes a top view (a) and a right side view (b). The screen 13 is supported above the main body 10 by the first connecting portions 11a and 11b and the second connecting portions 12a and 12b. The projector 14 projects the calculation result on the screen 10.

  At this time, the main body 10 is configured to be slidable in the direction of the projection plane parallel to the ground plane. With this configuration, the input unit included in the main body unit 10 can be brought close to the operator who operates while looking at the projection plane, so that the distance between the operator and the projection plane can be maintained.

  Next, a portable information processing apparatus according to the second embodiment of the present invention will be described. The portable information processing apparatus according to the second embodiment of the present invention can take an opened state and a folded state.
