Description

[Detailed description of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to allow a single display device to display many types of display by making the display screen rotatable.

[0002] Conventionally, general-purpose display devices only have a fixed display screen or one that is variable only in the horizontal direction, and are only capable of displaying a certain type of information, such as information for processing slips. In some cases, the display screen can be used effectively without any problems, but when displaying many types of information, such as displaying information for slip processing, displaying information for text processing, etc. A horizontally long display screen is easy to use, and if this horizontally long display screen is used as it is for text processing, it will be difficult to read, or if a display method that is easy to read is used, a large part of the display screen will be wasted. There are drawbacks.

The present invention solves the above-mentioned drawbacks by making the display screen rotatable and changing the position, direction, etc. of displayed characters in accordance with the rotation angle. The details will be explained by way of example in the accompanying drawings.

[Example] Fig. 1 is a front view of the device of the present invention, Fig. 2 is a side view thereof, Fig. 3 is a vertical sectional side view of the same main part, and Figs. 4 and 5 are A-A in Fig. 3, respectively. , is a cross-sectional view taken along line B-B, and shows the operating table (1
) A display screen (
A fixed shaft (3) that supports 4) is inserted and supported.

The fixed shaft (3) has two pairs of recesses (5) (5) (5') spaced apart from each other at a predetermined angle on the outer peripheral surface at a predetermined position near the end on the side where the support (2) is inserted. ) (5'), and a notch (6) is provided on the outer circumferential surface at a predetermined position closer to the display screen than the recess over an angular range that is approximately equal to the separation angle between the recesses; A small protrusion (7) is provided on the opposite side to (6).

Further, a shaft hole (8) through which the fixed shaft (3) can be inserted is bored at a predetermined position of the support column (2).
) is provided with a pair of leaf springs (9) having protrusions (10) that can be engaged with the recesses at positions corresponding to the recesses (5), (5), (5'), and (5'); A projection (11) that engages with the notch (6) is provided in the shaft hole (8) at a position corresponding to the notch (6).

Therefore, for example, if the rotatable angle of the display screen (4) is 90 degrees, when the display screen (4) is in the horizontal position (see FIG. 1), the protrusions (10) (10) engages with the recesses (5) (5). On the other hand, when the display screen (4) is in the vertical position (see Figure 6), the protrusions (10) (10)
are engaged with the recesses (5') (5').

Furthermore, a display control section is built into the operation console (1), the block diagram of which is shown in FIG.

(13) is the main controller, (14)
(15) is buffer memory 1 that stores display data from the main controller (13).
The buffer memory 2 (14) rearranges and stores the display data stored in (14), and (16) instructs the angle by supporting from a keyboard etc. in response to manual rotation of the display screen.
An angle indicator (17) outputs a signal to control a main controller (13) and a character generator control circuit (17) to be described later, and inputs data from buffer memory 1 (14) or buffer memory 2 (15) and outputs each data. (18) is a character generator that outputs character dot information using the address signal as an input signal; (19) is a character generator control circuit that outputs character dot information corresponding to the character dot information;
A video controller (20) capable of displaying a predetermined character in synchronization with raster scanning in the character generator control circuit (17) and a video controller (1
9) is a timing generator that provides a timing signal.

The operation of the display device having the above structure is as follows.

As shown in FIG. 1, when the display screen (4) is manually set to the horizontal position, when inputting from the keyboard etc. that the display screen is horizontal, a signal is sent from the angle indicator to the main controller (13). ) and the character generator control circuit (17).

Therefore, the display data stored in the buffer memory 1 (14) is transferred to the character generator control circuit (14).
7), the character generator (1
8) to send character dot information to the video controller (
19) and further display predetermined characters on the display screen.

In this case, the scanning direction of the display screen (4) is as shown by the arrow in FIG. It is now possible to display characters.

Next, as shown in FIG.
) is manually set to the vertical position, when inputting from the keyboard or the like that the display screen is horizontal, a signal is applied from the angle indicator to the main controller (13) and the character generator control circuit (17).

Therefore, the display data stored in buffer memory 1 (14) is rearranged and stored in buffer memory 2 (15).
), and the display data stored in the buffer memory 2 (15) causes the character generator control circuit (
17), a predetermined character can be displayed on the display screen (4) through a character generator (18) and a video controller (19).

In this case, the scanning direction of the display screen (4) is as shown by the arrow in FIG. 6. Therefore, when displaying the letter A, it is scanned in the direction shown by the arrow (22) in FIG. It is now possible to display characters.

[0017] In the above, the rotation angle of the display screen (4) is set to 90
Although only the embodiments with 90%
The rotation angle is not limited to an arbitrary rotation angle, and it is possible to set an arbitrary rotation angle by changing the interval between the recesses, the size of the notch, etc.

As described above, since the display screen is rotatable, the present invention has unique effects such as making it easy to read even when displaying multiple types of information and making effective use of the display screen. .
