However, in the above-described data processing apparatus, the lid provided on the display unit is merely provided rotatably on the apparatus main body. In the standing state, the display section is always in the horizontally long state. For this reason, it is preferable when creating a chart or the like, but when creating a document or the like, the number of characters in one line is large.
Since the number of lines is small, there is a problem that it is not preferable.
Therefore, it has been considered that the lid provided with the display unit can be changed to either the horizontal state or the vertical state. However, the lid is pivotally supported and the lid is rotated about the axis. In this case, the height of the lid body largely moves up and down between the horizontally long state and the vertically long state, and the display unit is difficult to see. An object of the present invention is to make the height position of the lower surface of a horizontally long display device main body substantially constant regardless of the rotation state of the display device main body.

As shown in FIG. 2, a pair of left and right cylindrical shafts 6a, 6a provided on the rear side edge of the device main body 1 has a hinge 6 for attaching the support 3 to the device main body 1, as shown in FIG. This is a structure in which the support 3 is rotatably attached to the device main body 1 by being inserted into both side surfaces. The pivot 7 for attaching the lid 2 to the support 3 is provided at the upper left from the center on the back surface of the lid 2 as shown in FIGS.
Is rotatably and movably mounted in a long hole 8 provided at the upper left of the horn. That is, as shown in FIG. 3, the rotating shaft 7 has a cylindrical shape, and is provided so as to protrude from the back surface of the lid 2.
A flange 9 is provided at the tip. This flange portion 9 comes into contact with a part of the hole edge of the long hole 8 so that
This is for preventing the rotating shaft 7 from coming out of the long hole 8, and a rotation regulating projection 10 is provided on a part of the lower surface thereof. As shown in FIG. 2, the elongated hole 8 of the support 3 is provided in the upper left of the support 3 in a laterally long direction, and the rotation restricting projections 10 are removably engaged with both end edges thereof. Recesses 11 and 12 are provided. Further, a plate-like spring member 13 is provided between the lid 2 and the support 3 in the vicinity of the rotation shaft 7. The spring member 13 urges the lid 2 and the support 3 so as to push them apart, and engages the rotation regulating projection 10 with one of the engagement recesses 11 and 12 of the elongated hole 8.

The electrical connection between the device main body 1 and the lid 2 is made such that the signal lines 14, 14 in the device main body 1 are guided into the support 3 through the cylinder shafts 6 a, 6 a of the hinge 6. Signal line 1
4 and 14 are connected by being guided into the cover 2 through the cylindrical rotary shaft 7 of the cover 2 attached to the long hole 8 of the support 3. The rotation restricting protrusion 10 of the rotating shaft 7 is configured as a contact of a switch, and a contact of a signal line 15 is provided in the engagement recess 12 at the right end of the long hole 8. A switch is constituted by the contact point of the rotation restricting projection 10 and the contact point of the signal line 15. The switch switches the display on the display unit 5 between a landscape display and a portrait display.

Next, a case where the above-described data processing device is used will be described. When inputting data in the landscape display, first, the hinge 2 of the device body 1 is centered, and
Is turned by a predetermined angle with respect to the device main body 1 to stand up. Then, as shown in FIGS. 1 and 8, the key 4 appears on the upper surface of the device main body 1 so as to be able to be input, and the lid 2 stands upright, and accordingly, the display unit 5 is also arranged horizontally. . Therefore, in this state, the display unit 5 is in the landscape display, which is suitable for inputting a chart or the like. In addition,

Therefore, in this state, since the display unit 5 is in the portrait display, the number of characters in one line is small and the number of lines is large, which is suitable for inputting a document or the like.

Further, when carrying the entire apparatus, the cover 2 is rotated about the rotation shaft 7 of the cover 2 with respect to the support 3 so that the cover 2 is horizontally elongated with respect to the device body 1. The lid 2 is pivoted about the hinge 6 to be superimposed on the device main body 1. As a result, the entire device becomes compact, and the key 4 and the display unit 5 are protected by the lid 2, so that the device can be carried very well.

The present invention is not limited to the above embodiment. For example, the rotating shaft 7 is not necessarily the lid 2
It is not necessary to be provided on the support 3 and may be provided on the support 3. In this case, a long hole 8 may be provided on the back surface of the lid 2. In addition, the rotating shaft 7 and the long hole 8 may be provided anywhere as long as the rotating shaft 7 and the elongated hole 8 can be rotated with the lid 2 standing upright with respect to the device main body 1.
