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. This invention relates to a cordless multi-item input device that allows selection 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, in this type of input device, items such as characters and symbols are filled in in advance or a plurality of sheets with space for writing are loaded into the input device, and the display is performed by changing the sheets according to the software program. By exchanging the contents of the items and selecting and inputting the necessary items 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.

Purpose of the Invention The present invention is intended to solve such problems, and to reduce the amount of movement of the sheet as much as possible when replacing the sheet, thereby shortening the replacement time or shortening the sliding distance between sheets to prevent damage to the sheet. . In other words, the present invention has already been filed in a patent application filed in 1973.
-29415 or Japanese Patent Application No. 100143, etc., both of these methods have item display windows on all sheets, making it easy to find holes when replacing sheets. In the past, sliding stability was lacking, but in order to solve this problem, a method was proposed in Japanese Patent Application No. 57-83669 in which perforated sheets and transparent sheets were alternately laminated. This is related to patent application No. 57-83669.

Here, in order to select an arbitrary sheet from the 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 seat is pushed or pushed, stress will be generated on the seat and the seat will not be able to withstand long-term use, and if the seat is held firmly to prevent damage to the seat, it will not be easy to replace the seat. Therefore, the present invention solves these problems, and allows the use of thin sheets or sheets that have deteriorated over time, improving the long-term reliability of the sheet, and making it extremely easy to replace the sheet. The purpose is to provide a multi-item input device.

Structure of the Invention In order to achieve the above object, the present invention is provided for each of a plurality of item entry sheets, and moves the sheet a predetermined distance by holding the front end and rear end of the sheet. A sheet cartridge comprising a plurality of sheet holding members that can be moved and a plate member in which the sheet holding members are arranged in parallel and each movable by a predetermined distance; A multi-item input device main body comprising a sheet moving member that engages with any one of the members and a sheet driving means capable of moving the item entry sheet held by the sheet moving member by the predetermined distance. The sheet cartridge is configured so that it can be attached to and removed from the main body when desired.This makes it possible to use the item entry sheet for a long period of time, improves the reliability of the sheet, and makes it extremely easy to replace the sheet. This is something that has become easy to do.
