## Title
Unitary computing device having orientation adjusting mechanism

## Abstract

A unitary computing device includes a rotary member and a support for supporting the rotary member and allowing a rotation of the rotary member. The unitary computing device also includes an optical disk drive and at least one orientation adjusting mechanism. The orientation adjusting mechanism includes a first linkage bar rotatably connected to the support, a second linkage bar rotatably connected to the first linkage bar and the optical disk drive, and a third linkage bar rotatably connected to the rotary member and the optical disk drive, which constitutes a linkage bar mechanism to adjust an orientation of the optical disk drive.

## Background
BACKGROUND
1. Technical Field
The present disclosure relates to unitary computing devices and, more particularly, to a unitary computer having an orientation mechanism to adjust orientation of an optical disk drive.
2. Description of Related Art
Personal computer systems are, by now, well known in the art and have been supplied in a number of different configurations, including desktop systems with CPU housings separate from monitors, notebook systems, and unitary systems. In unitary systems, commonly known as all-in-one desktop computers, information handling elements of the system such as the central processor, associated memory, and drives such as optical disk drives and hard disk drives are housed in a common housing with the display or monitor.
In the unitary system, the orientation of the optical disk drive changes as the orientation of the display is adjusted. Generally, to ensure that the optical disk drive can read data reliably from an optical disk, it is better to keep the optical disk drive horizontal or vertical. It is desirable to provide a unitary computer system that includes an orientation adjusting mechanism to adjust the orientation of the optical disk drive.



BRIEF DESCRIPTION OF THE DRAWINGS
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the unitary computing device. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
FIG. 1 is an isometric view of a unitary computing device in accordance with an exemplary embodiment.
FIGS. 2 and 3 are side views of the unitary computing device of FIG. 1, which show two different orientations of a rotary member and orientation of an optical disk drive stays the same.



DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIGS. 1-3, a unitary computing device 100 includes a support 10 and a rotary member 20. The rotary member 20 is pivotably connected to the top of the support 10 via a hinge 30. In the embodiment, the rotary member 20 is an LCD display.
The unitary computing device 100 also includes an optical disk drive 40 and two orientation adjusting mechanisms 50. The optical disk drive 40 is movably connected to the support 10 and the display 20 by the orientation adjusting mechanisms 50. In the embodiment, the orientation adjusting mechanisms 50 have the same components arranged in the same manner. The number of the orientation adjusting mechanisms 50 may be changed according to need.
Each orientation adjusting mechanism 50 includes a first linkage bar 60, a second linkage bar 70, and a third linkage bar 80. Two ends of the first linkage bar 60 are rotatably connected to the support 10 and the second linkage bar 70, respectively. Two ends of the second linkage bar 70 are rotatably connected to the first linkage bar 60 and the optical disk drive 40, respectively. Two ends of the third linkage bar 80 are rotatably connected to the optical disk drive 40 and the display 20, respectively. The support 10, the display 20, the optical disk drive 40, and the orientation adjustment mechanisms 50 constitute a linkage bar mechanism.
In the embodiment, a plurality of frictional axles 90 are used to rotatably connect the support 10, the display 20, the optical disk drive 40, and the orientation adjustment mechanisms 50, such that sufficient frictions can be provided therebetween. Due to friction, each of the linkage bars 60, 70, and 80, and the display 20 can be positioned in any desired orientation.
For ease of adjusting the orientation of the optical disk drive 40, the linkage bars 60 and 80 have the same length. The lengths of the linkage bars 60 and 80 are less than that of the linkage bars 70. In the embodiment, the lengths of the linkage bars 60 and 80 are about one third of the linkage bars 70.
FIG. 2 shows that the display 20 is tilted with respect to the support 10, and that the optical disk drive 40 stays substantially vertical. As shown in FIG. 3, after the display 20 is rotated from the tilted orientation in FIG. 2 to a vertical orientation, the optical disk drive 40 can be adjusted to remain vertical.
While various embodiments have been described and illustrated, the disclosure is not to be constructed as being limited thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
