Description

[Detailed description of the invention] The present invention relates to a terminal device used in a computer system, and in particular has a multi-item display section, and allows users to select necessary items from among the many items displayed on the display section. This relates to a cordless multi-item input device that uses key switches and the like.

In this type of device, it would be a great advantage to be able to change the items displayed on the display section as needed, so various input devices that can change the displayed items have been devised. There is.

According to this device, a plurality of recording media such as sheets, cards, tapes, etc., on which the contents to be recorded, such as characters and symbols, are pre-written or have space for writing are loaded into the device, and the required recording is performed. By selecting a medium and positioning it on the display section, it is possible to display part of the recorded contents stored in the device on the multi-item display section.

By exchanging the contents of display items according to the software program and selecting and inputting necessary items from a plurality of items displayed on the display unit, various information processing operations can be performed.

Unlike conventional input devices that input codes using a keyboard, this type of device is characterized by the fact that it can display characters, symbols, and other normal everyday terms, making it easy to input even if you are not an expert operator. be able to.

The key points required of the device are ease of exchange operation of selecting the required medium from multiple recording media and presenting it on the display;
These include reliability and the time required for selection and replacement.

Conventionally, two methods have been devised for an item exchange operation in which display items displayed on a display unit are exchanged by selecting a necessary medium from a plurality of recording media: a manual type and an automatic type.

A conventional example will be explained with reference to FIGS. 1 and 2.

FIG. 1 shows an input device having a manual item exchange function called a book type, in which 1 is a card-shaped recording medium, and several to several sheets are bound into a book.

It can be spread out one page at a time like a book, and the pages can be changed manually.

Reference numeral 2 denotes pushbutton switches, and the items written in the display space 3 provided in the vicinity of each switch are used when inputting.

Card 1 can be displayed on both sides.

This method is manual and requires manual exchange of items, is complicated, and is not suitable for processing input tasks quickly.

FIG. 2 shows a device having an automatic item exchange function called a roll winding system.

In this system, a strip-shaped recording medium 4 is held and driven by two rolls 5 and 6, and one block is selected from a plurality of character and symbol blocks recorded on the recording medium 4 in a display section 7. This is a method to display it on the screen.

This differs from the book system shown in FIG. 1 in that items can be exchanged automatically and the operation is simple, but it has a drawback in terms of exchange speed.

Items such as characters and symbols are divided into blocks on a strip-shaped recording medium 4 and recorded on the roll 5.
, 6 to run the recording medium and select the required block, when exchanging an item, the exchange time varies depending on the position of the selected block, and when exchanging an item to an adjacent block, the exchange operation is completed in a short time. When replacing the blocks at both ends, the replacement time will be significantly longer.

For example, when there are 20 item recording blocks, the longest exchange time is 20 times longer than the shortest time, typically 4 to 5 seconds.

Furthermore, the replacement time varies widely depending on the position of the item recording block to be replaced, which is a problem in use.

The present invention eliminates the drawbacks of the conventional example and provides an input device that automatically exchanges items at high speed and reliably.

Hereinafter, embodiments will be described in detail with reference to the drawings.

FIG. 3 shows the external appearance of an embodiment of the present invention, in which a multi-item display panel 11 provided on the inclined surface of the device 10 has display sections 12 arranged at equal intervals both vertically and horizontally. In addition, in the vicinity of the display section 12, item switches 13 corresponding to the display sections are arranged.

The display section 12 is transparent and has a structure that allows the interior to be seen through, so by placing a display board inside, characters, symbols, etc. written on the display board can be displayed through the display section 12. It happens.

The portion of the display panel 11 other than the display section 12 is opaque.

The device 10 has a function of exchanging the display board, which is a recording medium, and can automatically exchange the display with another recording medium by an exchange operation.

Figures 4 and 5 show the display using different display boards, and the display board in Figure 4 shows 1.2.3.4.
While the numbers are shown as ``...'', on the other display board in Figure 5, the characters are changed to ``i, ro, ha, ni...''.

This device can store 5 to 30 display boards as recording media, and each display board has items written with different characters and symbols.

By selecting one of the display boards stored according to the software program and placing it on the display panel, the necessary recorded content for each item will be displayed.

Further, by selecting a necessary item from among those displayed on the display panel 11 and operating the item switch 13 provided on the display panel 11, the necessary signal can be input.

FIG. 6 shows the internal configuration in detail. Below the multi-item display panel 11 are a plurality of display boards 14a, 14b, 14.
c... are arranged in a layered manner, and symbols, characters, etc. are written at predetermined positions on each display surface.

Here, transparent plates are used for every other display plate 14a, 14c, and opaque plates are used for the display plates 14b, 14d sandwiched between them.

A through hole 15 having approximately the same size as the display section 12 disposed on the display panel 11 is provided between the letters on the opaque plate.

A tension spring 16 is connected to one end of each of the display boards 14av14b1, and a tension mechanism using a solenoid 17 is connected to the other end.

When the solenoid 17 is not energized, the display plates 14a, 1
4b, .

That is, in the transparent display boards 14a and 14c, the transparent material between the characters is also in the opaque display boards 14b and 14.
At d, the through-hole 15 overlaps the display section 12, so that the characters, symbols, etc. on each display board are hidden behind the opaque section of the display panel 11 and cannot be seen from the display section 12.

Next, when the solenoid 17 connected to the display board (for example 14d) to be displayed is energized, one end of the swinging lever 19 with the fulcrum shaft 18 as the rotation center is attracted, and the tension lever 20 connected to the other end is attracted. is drawn.

Since the other end of the tension lever 20 is connected to the display board 14d via the hook pin 21, the display board 14d is pulled a predetermined distance, and characters, symbols, etc. appear below the display section 12.

FIG. 7 is a longitudinal cross-sectional view of the display board storage section, and there are a plurality of display boards 14a at the bottom of the display panel 11.

14b, 14c, . . . are housed, and the front and rear edges are fitted into the rail members 22a, 22b, so that they can be slid laterally.

FIG. 8 is a cross-sectional view of the display board storage section, and below the display section 12 of the display panel 11, display boards 14a, 14b,
In 14d, only the characters or symbols of the display plate 14c, in which the transparent portion or the through hole 15 is moving against the tension spring 16 due to the energization of the position solenoid 17, are located below the display portion 12 and are visible.

When the solenoid 17 is de-energized, the tension spring 16 causes the display board 14c to return to its home position.

If the display boards 14a, 14d, .

In addition, if the display board is made of an opaque material, the through holes 15
As a result, normal operation is inhibited due to a phenomenon in which the through-hole ratios are stuck together.

By alternately overlapping transparent display plates and opaque display plates having through-holes as in the present invention, smooth exchange operations and clear display can be achieved.

Further, in the embodiment, an electromagnetically operated solenoid was used as the tensioning mechanism for the display board, but other methods such as using the power of an electric motor or manual methods may also be considered.

As explained above, since the present invention is structured, the item exchange operation for selecting and displaying the required recording medium can be performed easily and quickly, and is highly reliable, simple in structure, and small in size. It has many advantages such as being able to provide it at low cost.
