Description

[Detailed description of the invention] This invention relates to a multi-item input device, and in particular, it positions subtitles corresponding to a plurality of key switches arranged in a row.
The present invention relates to a multi-item input device that inputs item-specific data displayed in correspondence with 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, a key definition means such as an item sheet (subtitles) or an item booklet is provided on the keyboard, and by exchanging this item sheet, the definition of each key switch can be defined. I was trying to change it.

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. 41479/1989, the applicant of the present application proposed a multi-item input device that can randomly and automatically change the item sheet.

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 to position the selected subtitle at the defined position corresponding to the keyboard.

By the way, in order to attach one of the multiple subtitles wrapped around the rotating drum to the bottom of the keyboard as described above, it must be done smoothly so that the selected subtitle does not get caught in the middle. It is necessary to position it at the defined position corresponding to the keyboard.

Therefore, the main purpose of this invention is to provide a multi-item input device that is provided with a guide section that allows subtitles to be reliably delivered to a keyboard defined position with a relatively simple configuration.

In summary, this invention arranges first and second guide parts near a rotating drum around which a plurality of subtitles are wound, with a predetermined gap between them.

The first guide part has an arcuate outer circumferential surface, the second guide part includes an arcuate inner circumferential surface that faces the arcuate outer circumferential surface of the first guide part and runs along the outer circumferential surface; A comb tooth section extending near the subtitle insertion section is provided on at least one of the outer circumferential surface of the first guide section and the inner circumferential surface of the second guide section, and a comb tooth section extending near the subtitle insertion section is provided to select among a plurality of subtitles sent from the rotating drum. Only one subtitle inserted is guided from the gap between the first and second guide parts to the subtitle insertion part on the bottom surface of the keyboard.
