Description

The present invention relates to an electronic device, and more particularly to an electronic device having a display.

[Prior Art] Conventionally, as this type of electronic device, there is known an electronic device in which a display device can be tilted toward the front side of the operator in order to make it easier for the operator to see the display screen.

[Problems to be Solved by the Invention] However, in such a conventional apparatus, although it is acceptable for only the operator to see, for example, a display image is presented to a customer who is in a business meeting and explained. At that time, it was very inconvenient because the customer had to look into the display device or pick up the electronic device itself and change the direction to see the display screen.

There were also electronic devices that could tilt the display to the opposite side of the operator, but in that case, the customer on the opposite side of the operator turned it upside down. I could only see the image.

An object of the present invention is to eliminate such inconveniences of the related art and provide an electronic device having excellent usability.

[Means for Solving the Problems] In order to achieve the above-mentioned object, in the present invention, a display for displaying an image, a changing means for changing the direction in which the display faces, and a change made by the changing means. Based on the direction in which the display is directed, a determination means for determining whether or not the orientation of the image displayed on the display on the display should be changed, and the orientation of the image should be changed by the determination means. Re-display means for changing the orientation of the image and re-displaying the changed image on the display device when determined.

[Operation] With the above configuration, whether to change the direction of the display unit that displays an image and whether to change the direction of the image displayed on the display unit on the display unit based on the changed direction of the display unit. If it is determined that the orientation of the image should be changed, the orientation of the image is changed, and the changed image is displayed again on the display.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an external configuration of a portable terminal device to which the present invention is applied.

In the figure, reference numeral 1 is a main body of a portable terminal device, and 2 is a display unit pivotally supported at its both ends in an opening 1A provided in the main body 1, and includes a liquid crystal display 7 and the like. Reference numeral 3 is a dial that is interlocked with the pivot shaft and is used for adjusting the tilt direction and tilt angle. Reference numeral 4 is a keyboard, and 5 is a power switch.

Further, in FIG. 3, reference numeral 6 is a detection switch provided on the bottom wall of the portable terminal device body 1.

FIG. 4 shows the configuration of the control system of this portable terminal device.
Reference numeral 10 is a CPU, 11 is a ROM storing a control program, 12 is a RAM for temporarily storing display data, and 13 is an interface to which the detection switch 6 is connected. Reference numeral 14 is a port circuit for connection with a host computer, 4 is the above-mentioned keyboard, and 7 is a liquid crystal display.

Then, normally, when used by one person, the display 2 is tilted to the front side of the operator A by adjusting the dial 3 as shown in FIGS. 1 and 3 (a).

On the other hand, when conducting a business negotiation or the like while confronting the customer B, the operator A first performs an input operation from the keyboard 4 in the state shown in the first diagram, so that the customer B can see the display image of the obtained result. As shown in FIGS. 2 and 3B, the dial 3 is adjusted to tilt the display 2 toward the customer B side.

At this time, the display image may be left as it is, but in the present embodiment, an example in which the display image is inverted in the vertical direction by the detection switch 6 being turned on by the tip portion of the display 2 is shown.

That is, when the operator A looks (hereinafter referred to as A mode), the detection switch 6 is in the off state, but the customer B
When it is tilted to the side (hereinafter referred to as B mode), it is turned on.

Therefore, when the detection switch 6 is turned on, the CPU 10 receives a signal via the interface 13 and replaces the contents of the display buffer in the RAM 12.

For example, FIG. 5 shows the contents of the display buffer of the liquid crystal display 7 in bit units for each address.
The A mode displayed as a normal image when viewed from the side is switched to the B mode in which the address and contents of the display buffer are reversed by the ON operation of the detection switch 6 for display. That is, the contents of address 0 are inverted and transferred to address n.

The contents of this display buffer are displayed on the liquid crystal display 7.
FIG. 6 shows an example expressed in accordance with the display screen of FIG.

In this embodiment, the display image is inverted in the vertical direction when it is tilted to the side opposite to the operator, so that it is very easy for the customer to see.

[Effects of the Invention] As is apparent from the above description, according to the present invention, the direction of the image displayed on the display can be changed based on the direction in which the display is facing. Even when tilted to the opposite side of the operator, the customer on the opposite side of the operator can see a normal image in which the vertical direction is not upside down.
