Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an input device used in a computer system, and in particular has a multi-item display section, and is capable of selecting necessary items from among the multiple items displayed on the display section. The present invention relates to an information input device that is selected and input using a corresponding key switch.

Configuration of conventional examples and their problems Unlike conventional devices that input codes using a keyboard, such input devices are characterized by being able to display everyday terms such as letters and symbols, as well as pictures, etc., and can be easily used even by non-specialized operators. This allows input operations to be performed. By the way, with this type of input device, multiple sheets are loaded into the input device on which items such as characters and symbols are pre-filled or have space for writing, and the sheets can be changed according to the software program. By exchanging the contents of display items and selecting and inputting a necessary item from the plurality of items displayed, various information processing tasks can be performed.

Conventionally, such an input device uses a book method in which multiple sheets are bound like a book and the necessary pages are turned over, or a long strip-shaped sheet is provided in a roll between two shafts, and the long strip-shaped sheet is placed at a predetermined position. Various methods have been proposed, such as displaying on the display, or winding multiple sheets on the same axis at equal intervals and selecting an arbitrary sheet depending on the rotation angle of the shaft, but in the case of the book method, The operator must perform page exchange operations each time. In addition, although the other methods mentioned above can automatically replace the sheets, the amount of sheet movement in the exchanger is large, making it difficult to shorten the replacement time, or the amount of sliding between sheets is large, causing damage to the sheets. There were some problems, such as it was easy to get stuck. In order to solve this problem, reduce the amount of sheet movement that occurs when replacing the sheet,
It is necessary to shorten the replacement time or the sliding distance between sheets. In addition, in order to select an arbitrary sheet from a group of sheets on which multiple items have been filled in and move that sheet to a predetermined position, a part of the sheet must be driven in some way, but it is necessary to pull a part of the sheet. If the sheet is pushed or pushed, stress will be generated on the sheet and it will not be able to withstand long-term use.Also, a thin sheet will easily deform depending on the temperature and humidity of the environment in which it is used, so it is important to move the deformed sheet. This is difficult, and if the sheet becomes detached from the moving mechanism, it may become folded or jammed.

OBJECTS OF THE INVENTION The present invention solves these problems, and aims to provide an information input device that can sufficiently withstand long-term use even with thin sheets or deformed sheets.

Structure of the Invention In order to achieve the above object, the present invention provides a cylindrical pin that is provided corresponding to each of a plurality of item entry sheets and that fits into the opening holes at the front and rear ends to hold the item entry sheet. a sheet moving member for moving the item entry sheet,
and a switch for inputting information corresponding to the items on the item entry sheet, and by forming an uneven shape around the cylindrical pin and holding the item entry sheet at the front and rear ends. Therefore, the item entry sheet is configured to prevent it from coming off the cylindrical pin,
As a result, reliability does not deteriorate even if the item entry sheet is used for a long period of time, and the reliability of the page selection operation, which is the most important for a multi-item input device, can be ensured.
