Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tablet-type information input device, and more particularly to an improvement in a display sheet placed on the tablet.

Conventionally, various types of information input devices using tablets, such as capacitive coupling, electromagnetic coupling, and photoelectric coupling, are known.In these information input devices, a display sheet is placed on the tablet, By pointing the letters, numbers, symbols, etc. displayed on this sheet with a probe,
A code signal corresponding to the designated characters, numbers, symbols, etc. can be generated.

In this case, each character on the display sheet corresponds to each key area formed on the tablet.

It is also known that this type of device can selectively use multiple display sheets bound in booklet form, but the correspondence between the area displaying letters, numbers, symbols, etc. on each display sheet and the tablet This may cause malfunctions such as forming symbols corresponding to letters, numbers, or symbols different from those indicated by the probe.

In addition, there is also a display sheet that can be attached and removed one by one onto the tablet, but in order to position the display sheet on the tablet, the corners of the display sheet must be fixed with a frame, which is a cumbersome task. When many display sheets are used interchangeably, the frame must be removed or fixed each time a display sheet is replaced, which is an inconvenience.

On the other hand, if characters, numbers, symbols, etc. to be displayed on the display sheet are displayed by printing etc. on the surface of the display sheet,
There is an inconvenience that the displayed characters, numbers, symbols, etc. disappear when the probe is instructed frequently.

On the other hand, there are some display sheets in which the surface is coated with a translucent or transparent film, but in this case there is an inconvenience in that letters, numbers, symbols, etc. cannot be rewritten.

Therefore, in order to solve the above-mentioned inconveniences of conventional information input devices, the present invention stores information in a single sheet type display sheet in a bag-like case so that it can be easily positioned and fixed on a tablet together with the case. It provides an input device.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The information input device 1 according to the present invention has a tablet 2 in the center of the operation surface 5 of the casing 20.

For example, in the case of a capacitive coupling method, a plurality of X-thin conductors 3 and Y-thin conductors 4 are arranged in a lattice shape with an insulator in between. After key segments are set around the respective intersection points, scanning signals are sequentially applied to the X-thin conductor 3 and the Y-axis conductor 4, respectively.

The operating principle of such a tablet is well known and will not be described here.

A notch or recess 6 corresponding to the effective area of the tablet 2 is formed in the operation surface 5 of the casing 20 .

A bag-like case 8 containing the display sheet I is placed in the recessed part 6 of the
is inserted snugly.

A probe 9 is provided on the operation surface 5 of the casing 20, and is connected to a control circuit (not shown) built into the information input device 1 via a cord 15.

Referring to FIG. 3, a plurality of display frames 10 corresponding to the size of each key segment of the tablet are printed on the surface of the display sheet 7, and each display frame 10 has letters, numbers, symbols, etc. It is displayed by printing or handwriting.

The bag-like case 8 is flexible, and at least one surface thereof is transparent or semi-transparent, and includes a synthetic resin film 11 and 12 that allows the characters, numbers, symbols, etc. displayed on the display sheet T to be visually recognized. These synthetic resin films 11.1
It has a spacer 13 located between the two films and adhered or welded to both films along its three edges.

This spacer 13 is a display sheet to be stored in the bag-like case 8).
The thickness is almost the same as No. 7.

In this case, one surface of the synthetic resin films 11 and 12 may be made rough to prevent light reflection.

In order to prevent the sheet 7 from being pulled out when the display sheet I is stored in the bag-like case 8, a stopper 14 is provided at the opening of the case 8.

This stopper 14 may be adhered or welded to the synthetic resin film 11 or 12.

According to the present invention, the display sheet 7 is stored in a bag-like case 8, the opening of which is closed, and the display sheet 7 is positioned within the case by the spacer 13 and the stopper 14. The bag-like case 8 containing the information input device 1 is inserted into the recess 6 provided on the operation surface 5 of the information input device 1 and brought into close contact with the tablet 2.

In the usage state, the operator can input the characters, numbers, symbols, etc. displayed on the display sheet I.
When the tip of the probe 9 is brought into contact with a symbol or the like, a signal corresponding to the letters, numbers, symbols, etc. displayed at the position where the probe 9 is brought into contact is input to the information human power device 1.

When replacing the bag-like case 8 used in the information input device 1, by twisting the synthetic resin film on the surface of the bag-like case 8 with your fingers, the bag-like case 8 bends and the information input device can be replaced easily. It can be taken out from the concave portion 6 of the operation surface 5 of No. 1.

Furthermore, if it is necessary to correct or change the letters, numbers, symbols, etc. displayed on the display sheet 7, the stopper 14 can be pinched with one finger on the synthetic resin film 11 or 12 to which it is not bonded or welded, and the bag can be removed. Since the opening of the bag-like case 8 can be easily opened, the stored display sheet 7 can be removed from the bag-like case 8 and the characters, numbers, symbols, etc. displayed on the display sheet 7 can be corrected or changed. be able to.

Since the present invention has the above-mentioned structure, the bag-like case containing the display sheet fits perfectly into the recess on the operation surface of the information input device, so even if the probe touches it during use, the display sheet will not be removed. Since it does not move and the bag-like case also does not move due to the operation surface of the information input device, the display frame of the display sheet can always correspond to the key segments of the tablet.

Furthermore, since the probe does not come into direct contact with the display sheet, the letters, numbers, symbols, etc. displayed on the display sheet do not wear out, so that it is always easy to distinguish between the letters, numbers, symbols, etc.

Furthermore, since the display sheet can be easily taken out from the opening of the bag-like case, it is easy to replace the display sheet and to easily correct or change the characters, numbers, symbols, etc. displayed on the display sheet.

The present invention can be applied to any information input device using a tablet and a probe, such as a known capacitive coupling method, electromagnetic coupling method, or photoelectric coupling method.

Additionally, the recess provided on the operation surface of the information input device may be of any shape as long as it can secure the bag-like case.
