Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-item input device, and more particularly, subtitles are inserted on the bottom surfaces of a plurality of key switches arranged in a row, and items are displayed corresponding to the subtitles from each key switch. The present invention relates to a multi-item input device for inputting data.

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 or an item booklet is provided on the keyboard, and the definition of each key switch is changed by exchanging this item sheet. That's what I was doing. 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 cumbersome.

Another key definition method is to wrap endless subtitles, which are a roll of multiple subtitles, around two rotating pulleys, place them under the keyboard, and automatically extract any subtitle from among the multiple subtitles. There is a way. However, it takes a long time to connect multiple subtitles in a roll and select the desired subtitle from among them, and the number of subtitles is limited even when forming a roll. There was a problem.

Therefore, the applicant of the present application proposed a multi-item input device that can randomly and automatically change subtitles in Japanese Patent Application No. 53-41479 (see Japanese Patent Application Laid-open No. 54-133832). This multi-item input device wraps a subtitle group consisting of a plurality of subtitles around a rotating roller, selects an arbitrary subtitle according to the rotation angle of the rotating roller,
After selecting a subtitle, the rotating roller is reversed to insert the selected subtitle onto the bottom surface of the keyboard.

However, in the above-mentioned multi-item input device, since the desired subtitle is selected from a group of subtitles wrapped around one rotating roller,
The number of subtitles that can be wrapped around the rotating roller is also limited. Therefore, there is a limit to the number of subtitles, and it is not possible to select a desired subtitle from among more subtitles.

Therefore, the main object of the present invention is to provide at least two subtitle groups in which a plurality of subtitles are wrapped,
To provide a multi-item input device with increased versatility by increasing the number of selectable subtitles by selecting a desired subtitle from at least two groups of subtitles and inserting it on the bottom surface of a keyboard. .

To summarize, this invention provides at least two or more rotating rollers each having a plurality of subtitles wrapped around them, and selects one of the subtitle groups wrapped around each rotating roller by a subtitle selection means. In addition, by specifying a desired subtitle among them using the subtitle specifying means, the roller around which the selected subtitle group is wound rotates, and in response to the detection means detecting the specified subtitle. Then, the rotating roller is reversed to insert the subtitle into the subtitle insertion section.

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.

The pulley 50a rotates a rotating roller 22a shown on the left side of FIG. 4 via a timing belt 24a. Further, the pulley 50b rotates the right rotating roller 22b shown in FIG. 4 via the timing belt 24b. The solenoid 45 switches the rotation of the motor 40 from the rotation of the rotating roller 22a to the rotation of the rotating roller 22b,
When the solenoid 45 is energized, it attracts the plunger 46 and causes the spur gear 43a to mesh with the spur gear 49b.

FIG. 6 is a schematic block diagram of one embodiment of the present invention. In this structure, when the upper switch 14 shown in FIG. 1 is operated, the flip-flop 68 is reset, and when the lower switch 15 is operated, the flip-flop 68 is set. When flip-flop 68 is set, a drive signal is applied to solenoid drive circuit 69. Thereby, the solenoid drive circuit 69 energizes the solenoid 45 of the rotation transmission mechanism 4 . At the same time, the set output of flip-flop 68 is applied to motor control circuit 67, causing motor 40 to rotate. Page selection switch 1
When any one of 1a to 11n is operated, a numerical value representing the number of pages of the designated subtitle is stored in the page selection circuit 65. The numerical value stored in this page selection circuit 65 is given to a comparison circuit 64. The counters 61a and 61b are each reset by a reference signal from the subtitle detection section 30 shown in FIG. 3, and are incremented by a timing pulse. That is, counter 6
1a and 61b are OR gates 62 and 63 that count timing pulses and output counts corresponding to a plurality of subtitles included in each of the subtitle groups 60a and 60b wound around rotating rollers 22a and 22b, respectively. The signal is applied to the comparator circuit 64 via. When the comparison circuit 64 determines that the numerical value provided from the page selection circuit 65 and the count output of the counter 61a or 61b match, it provides a match signal to the motor control circuit 67. In addition, the detector 16a
Or 16b provides a detection signal to the motor control circuit 67 via the OR gate 70 when detecting that the subtitle has contacted the guide board 16. The motor control circuit 67 stops the motor 40 based on the coincidence signal and the detection signal, and immediately reverses the motor 40.

Next, the specific operation of one embodiment of the present invention will be explained with reference to FIGS. 1 to 6. First, two rotating rollers 22a, 22 shown in FIG.
The subtitle group 60a wrapped around each of the subtitles 60a,
60b, the upper switch 14 or the lower switch 15 is operated. When the upper switch 14 is operated, the flip-flop 68 is reset and the solenoid 45 is not energized. To this end, spur gear 43a shown in FIG. 5 meshes with spur gear 49a, and rotation from motor 40 rotates rotating roller 22a clockwise via pulley 50a and timing belt 24a. Next, when one of the subtitles in the subtitle group 60a is designated by the subtitle selection switch 11, the numerical value corresponding to the designated subtitle is stored in the page selection circuit 65. Then, the comparison circuit 64 compares the numerical value given from the page selection circuit 65 and the count output of the counter 61a. The comparison circuit 64 derives a coincidence output, and when the detector 16a detects that the tip of the designated subtitle comes into contact with the tip of the guide plate 16, a stop signal is given to the motor control circuit 67. In response, motor control circuit 67 stops motor 40 and immediately reverses rotation. The rotation of the motor 40 causes the rotating roller 22a to rotate counterclockwise. As a result, the designated subtitle that is in contact with the tip of the guide plate 16 is inserted into the subtitle insertion section 17.

Next, when the lower switch 15 is operated, the flip-flop 68 is set and the solenoid 45 is energized. As a result, the spur gear 43a meshes with the spur gear 49b, causing the rotating roller 22b to rotate counterclockwise via the pulley 50b. Then, in the same manner as described above, a designated subtitle from among the subtitle group 60b wound around the rotating roller 22b is inserted into the subtitle insertion section 17.

In addition, in the above explanation, the upper subtitle 60
When subtitle 60b on the lower side is inserted into subtitle insertion section 17 after inserting subtitle 60b into subtitle insertion section 17, it has already been inserted. It is preferable that the lower subtitle 60b be inserted after the upper subtitle 60a is wound around the rotating roller 22a.

In addition, in the above embodiment, the two rotating rollers 22a and 22b are arranged on both sides of the subtitle insertion section 17, but three rotation rollers are provided so as to surround the subtitle insertion section 17 on three sides, and each A subtitle may be designated from among the wrapped subtitle group and inserted into the subtitle insertion section 17.

As described above, according to the present invention, at least two rotating rollers are arranged at both ends of the subtitle insertion section,
Since the desired subtitle is specified from among the group of subtitles wrapped around each subtitle and inserted into the subtitle insertion section, it is possible to increase the types of subtitles that can be inserted into the subtitle insertion section. The versatility of the multi-item input device can be further expanded.
