Description

[Detailed description of the invention] Industrial application field The invention has a multi-item display section, and the user selects the necessary item from among the many items displayed on the display section and inputs information etc. using the corresponding key switch. This relates to input devices.

Configuration of conventional examples and their problems The so-called cordless multi-item input device described above is different from conventional devices that input codes using a general keyboard, and is characterized by being able to display characters, symbols, etc. in everyday language, pictures, etc. Even non-specialist operators can easily perform input operations. In this type of input device, items such as characters and symbols are filled in in advance or multiple sheets with space for writing are loaded into the input device, and the sheets are changed according to the software program to display the information. By converting the contents of the items and selecting and inputting the necessary items from the multiple items displayed, it is possible to perform various information processing tasks, so it is suitable for use in computer systems. It is suitable for

Purpose of the invention The purpose of the invention is to improve the stability of operation and improve the reliability of the above-mentioned type of input device.

Structure of the invention In order to achieve the above object, the present invention has a structure in which opaque sheets having opening holes for display are stacked as a display medium, and a sheet arbitrarily selected from among the stacked sheets is moved. The length of the opening hole in the sheet is made larger than the distance the sheet moves.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the drawings. FIG. 1 shows an external view of a multi-item input device embodying the present invention. 10 is a switch panel, which has a plurality of transparent display windows 11 for reading items.
and a plurality of item switches 12 for each item display window.
A page display window 13 for displaying the contents of each page, a page selection switch 14 corresponding to the page display window 13, and a page number display window 15 for displaying the number of the selected page are provided. ing. 16 is a numeric keypad, and 17 is a function key for freely setting various functions.

The switch panel 10 can be opened freely as shown in FIG. 2, and FIG. 2 shows the state in which the door is opened. A sheet cartridge 18 is loaded with a plurality of item entry sheets 19 and a page content display sheet 20. Further, the seat cartridge 18 can be attached to the device main body 21, and the positioning pin 2
It can be easily attached and detached by fitting the positioning hole 23 into 2.

The configuration of the seat cartridge 18 will be explained in detail based on FIG. 3. The item entry sheet 19 is a stack of opaque perforated sheets based on paper. The perforated sheet has opening holes 26 at positions corresponding to the item display windows 11 of the switch panel 10, and a plurality of item entry areas 27 at non-display positions of the switch panel 10, that is, positions corresponding to the item switches 12. It is formed like a grid. Fill in any items or symbols as shown in Figure 3 with A, B, C, E, and O. Further, a part of the item entry sheet 19 is provided with a page display section 28 for displaying the page number of the sheet.
Reference numerals 29 and 30 are seat feet, which are provided at the front and rear ends of the seat, and are designed so that the positions of the seat feet 29 and 30 are not heavy for each seat when viewed from the plane direction of the seat. In the stacked state, the legs 29 and 30 of each sheet are arranged in parallel. Further, holding holes 31 and 32 are provided in some of the legs 29 and 30 of the seat. 33 is a plate substrate of the sheet cartridge 18. At the rear of the plate substrate 33, pairs of elongated holes 35 are provided, the number of which is the same as the number of item entry sheets 19. 3
4 is a sheet holding lever, and the plate substrate 33
The same number of sheets as the sheets are arranged in parallel on the back side of the sheet. The seat holding pin 36 is connected to the seat holding lever 34
The sheet retaining pin 36 is embedded in the notch 45 at the front and the long hole 35 at the rear so that the head protrudes from the plane of the plate substrate 33. The holding holes 31 and 32 of the item entry sheet 19 are fitted into the holding holes 31 and 32 to hold the front and rear ends of each page of the item entry sheet 19.

The seat holding lever 34 strokes between the length of the elongated hole 35 while holding the front and rear ends of the seat.
l ₂ movable and always tension spring 38
is urged to return in the direction of arrow A.

That is, by driving an arbitrary sheet holding lever 34 in the direction opposite to the arrow A, the item entered in the item entry section 27 of the item entry sheet 19 is moved to the opening hole 26 of the sheet, and the item is moved to the opening hole 26 of the sheet, and the item is moved to the opening hole 26 of the sheet. can be read through the item display window 11. Furthermore, the page display section 28 of the sheet
The page number of the sheet written in becomes readable through the page number display window 15 of the switch panel 10.

There is one problem when attempting to move any one of the perforated sheets stacked in this manner. This is because the end surface of the item entry section of the moving sheet interferes with the end surface of the opening hole of another sheet, which not only prevents smooth movement, but also causes the sheet to be deformed or damaged if the sheet is moved forcibly. Ta.

The present invention is specially designed to address this problem. FIG. 4 is a sectional view of the stacked item entry sheets 19, and the shaded area is the item entry section 27.
It is. Now, when an arbitrary sheet toy is moved in the direction of arrow B, the item entry section 27' of the sheet toy moves to the position of the opening hole 26 of another sheet, as shown in FIG. At this time, item entry section 2 of the seat toy
If 7' is deformed, when the sheet toy returns in the direction opposite to arrow B, the end surface 27A will come into contact with the end surface 27B of the item entry area of another sheet, and the sheet will not return.

In order to solve this problem, as shown in FIG. 6, the movement stroke l ₂ of any sheet in the direction of arrow B with respect to the hole dimension l ₁ of the opening hole 26 of the item entry sheet is such that l ₂ > l ₂ . It is configured to be a relationship.
With this configuration, even if the item entry sheet is deformed, the end surface 27A and the end surface 2 of the other sheet
7B can slide smoothly without contact.

Effects of the invention As is clear from the above explanation, according to the invention, even when perforated sheets are stacked, the holes between the sheets do not come into contact with each other, resulting in smooth operation and improved reliability. A high-performance multi-item input device can be provided.
