Herein, six frames 111, 112, 113, 114, 115 and 116 out of the seven frames 111, 112, 113, 114, 115, 116 and 117 are coupled two by two by using the joint parts 220, and a pair of frames formed of two coupled frames 111 and 112 and two coupled frames 113 and 114 are vertically arranged so as to be parallel to each other with an interval therebetween, and the pair of frames are connected by two coupled frames 115 and 116 with the joint parts 220 respectively, and further, one remaining frame 117 is coupled to an intermediate upper portion between the pair of frames so as to be parallel thereto by using the joint part 220 coupling the frames 115 and 116.
Also, the desktop PC 100 is provided with the image display module 120 having a frame receiving section 121 detachably supported so as to be slidable up and down by the pair of frames formed of two coupled frames 111 and 112 and the two coupled frames 113 and 114 out of the seven frames 111, 112, 113, 114, 115, 116 and 117, as illustrated in FIGS. 1 to 6. Also, the main unit module 130 having a frame receiving section 131 detachably supported so as to be slidable up and down by the upper frame 111 of the two coupled frames 111 and 112 of one of the pair of frames and the remaining one frame 117 is included.

The image display module 120 includes a display panel 122 having a display screen 122a on the front, and an up-and-down motion mechanism 123 that allows the display panel 122 to move up and down relative to the pair of frames formed of the two coupled frames 111 and 112 and the two coupled frames 113 and 114, as illustrated in FIGS. 1 to 6.
The up-and-down motion mechanism 123 includes two up-and-down dampers 1231 that are extendable poles extending in an up-and-down direction for supporting the display panel 122 in a flexible extending state; first members 1232 fixed to lower ends of upper and lower ends of the two up-and-down dampers 1231 and fixed to a lower right end and a lower left end of a rear surface of the display panel 122 to be slidable up and down relative to the pair of frames; and second members 1233 fixed to upper ends of the upper and lower ends of the two up-and-down dampers 1231 and fixed to the upper ends of the pair of frames with bolts 1235 to be slidable up and down relative to the display panel 122.
Also, the two up-and-down dampers 1231 are such that the second members 1233 fixed to the upper ends are coupled by means of a hollow steel pipe 1236 as illustrated in FIGS. 4 and 6, and a wire (not illustrated) passes through the steel pipe 1236. A lever 1234 is provided on the second member 1233 fixed to the upper end of the up-and-down damper 1231, on a side in which the first member 1232 is fixed to the lower right end of the rear surface of the display panel 122, out of the two up-and-down dampers 1231. When the lever 1234 is operated, a pressure is applied to both of the up-and-down dampers 1231 through the wire in the steel pipe 1236, enabling the display panel 122 to move up and down relative to the pair of frames formed of the two coupled frames 111 and 112 and the two coupled frames 113 ad 114.
