Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to each item input device, and in particular, to position subtitles corresponding to a plurality of key switches arranged in a row,
The present invention relates to an item input device for inputting item-specific data displayed corresponding to subtitles from each key switch.

For example, in a terminal device such as a computer, a plurality of key switches are arranged on a keyboard, and data is input from each key switch.

When inputting data for multiple items from such a keyboard, provide a key definition means such as an item sheet or item booklet on the keyboard, and change the definition of each key switch by converting this item sheet. I was trying to do that. For this reason, it is not possible to automatically change the item sheet from a computer, for example, and a person has to manually change the item sheet, which is complicated. Therefore, in Japanese Patent Application No. 53-41479, the applicant of the present application proposed a multi-item manual device capable of randomly and automatically changing item sheets.

This multi-item input device attaches one end of subtitles in the form of multiple item sheets to a rotating drum, separated by a predetermined rotation angle, and selects subtitles for any item according to the rotation angle of the rotating drum. After that, the rotating drum is reversed and the selected subtitle is inserted at the bottom of the keyboard. However, in the multi-item input device described above, since multiple subtitles are fixedly attached to the rotating drum, it is possible to select a desired subtitle from among the attached subtitles, but other item sheets cannot be selected. could not be easily replaced.

Therefore, the main object of the present invention is to provide a multi-item input device that has a relatively simple configuration and can exchange a plurality of subtitles with other subtitles with a simple operation.
To summarize, the present invention is such that one end of a plurality of subtitles is sequentially shifted and attached to a mount, and a locking portion is formed on the mount.

A protrusion is formed on the rotating drum to be engaged with the engagement part of the mount, and the mount with the subtitles attached is placed near the rotating drum, and the rotation drum is rotated so that the engagement part of the mount becomes the protrusion. The subtitles are secured by the protruding portions, thereby wrapping the subtitles around the rotating drum, and when the subtitles are removed, the rotating drum is reversed to disengage the protruding portions and the locking portions. . The above objects and other objects and features of the present invention will become more apparent from the detailed description given below with reference to the drawings.

That is, when the page selection switch 4 is operated, the rotating drum 5 rotates clockwise, and a page reading device (not shown) attached to the rotating drum 5 selects the item sheets 411 to 41.
The number of pages previously printed on n is read. When the desired page is reached, the rotating drum 5 is reversed. At this time, the other end of the selected item sheet is located near the guide portions 80 and 90 of the keyboard panel 2. By reversing the rotating drum 5, the other end of the selected item sheet is inserted into the subtitle insertion section 28, and the remaining item sheets are stored between the keyboard panel 2 and the sheet holder. Furthermore, when the page selection switch 4 is operated to select another item sheet, the rotary drum 5 rotates clockwise again, and the item sheet installed in the subtitle insertion section 28 is wound up. Then, when the selected item sheet is read, the rotating drum 5 is reversed again and the other end of the selected item sheet is attached to the subtitle insertion section 28. FIG. 8 is a side view of the main part showing a state in which the subtitles wound around the rotating drum are removed and stored in the storage section.

When replacing the subtitle 40 with another subtitle, the item sheet attached to the subtitle insertion part 28 on the bottom surface of the keyboard panel 2 is first wound onto the rotating drum 5. Then, the keyboard panel 2 is opened and the storage section 30 is attached to the input device 1. At this time, the tip of one of the item sheets 411 to 41n is exposed from between the guide shafts 61 and 64 and faces the opening surface of the storage section 30. Then, the rotating drum 5 is rotated clockwise until it is detected that the exposed item sheet is the last item sheet 41n, and when the item sheet 41n is detected, the rotating drum 5 is rotated counterclockwise. Thereby, the item sheet 41n comes into contact with the top end of the storage section 30 and is stored as the rotary drum 5 rotates.
Furthermore, the claw 5 operates in the opposite direction to that described in FIG. 7 above.
The upper sides 2 and 53 come into contact with the rear ends of the elongated holes 44 and 45, and the mount 40 is pushed into the storage section 30. And metal plate 4
3 is attracted to the permanent magnets 36 and 37 of the storage section 30 and the claw 52
, 53. In this way, the subtitles 40 in the storage section 30 are replaced. In addition, the subtitles 4 stored in the storage section 30
