Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-item input device, and more particularly, to a multi-item input device, in which subtitles are positioned 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 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 do. However, such key definition means require a person to manually change the item sheet, so it is not possible to change the item sheet automatically from a computer, for example, and each time the item sheet is changed. It is complicated and requires manual operation by humans.
Therefore, in Japanese Patent Application No. 53-41479, 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 subtitles at the defined position corresponding to the keyboard. By the way, in such a multi-item manual device, when specifying a desired subtitle, it is necessary to reliably select the specified subtitle and position it at the keyboard definition position. Therefore, the main object of the present invention is to provide a multi-item input device which has a relatively simple configuration and can reliably select a specified subtitle and position it at a defined position on the keyboard.

To summarize, the present invention has a plurality of subtitles wrapped around a rotating drum, and when a desired subtitle is specified by a subtitle specifying means, the rotating drum around which a plurality of subtitles are wound is rotated. A reference signal and a signal corresponding to each subtitle are generated according to the rotation of the subtitle.

Then, when a number of signals corresponding to the number corresponding to the designated subtitle are given after the reference gogo is given, the rotating drum is stopped, and when the detection means detects the end of the designated subtitle, the rotating drum is rotated. The drum is reversed and the subtitles are displayed on the subtitle display unit. 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.

Through holes 911 to 91m, the number of which is equal to the number of item sheets (n+1), are bored in the outer periphery of this rotary disk 91, and one through hole 92 is bored in the inner periphery. Then, a U-shaped metal fitting 93 is provided so as to sandwich the rotating disk 91 therebetween. Two light emitting elements (not shown) such as light emitting diodes are attached to one side of this metal fitting 93,
On the other side, there are two light-receiving elements such as phototransistors 9
4,95 installed. When the rotary disk 91 rotates, the light receiving element 94 detects light provided from the light emitting element through the through hole 92 and generates a reference signal. In addition, the light receiving element 9
5 detects the light given from the light emitting element through the through holes 911 to 91m and generates a timing pulse. On the chassis of the input device 1, a sheet holder 22 for receiving the remaining item sheets other than the selected item sheet is connected to the guide shaft 6.

The light receiving element 812 detects it. Note that the item sheet 40 is made of an elastic material such as Mylar paper, and is used for the item switch 3 shown in FIG.
Multiple types of items are preprinted in correspondence with...

Further, at each terminal end, a light emitting element 8 of the guide section 81 is provided.
A reflective film is formed to easily reflect the light projected from 11. FIG. 5 is a schematic block diagram of an item sheet selection section included in one embodiment of the present invention, and FIG. 6 is a waveform diagram of each part in FIG.

Next, with reference to FIGS. 1 to 6, a specific operation for selecting a desired item sheet and mounting it on the subtitle viewing section 28 will be described.

When you operate page selection switch 4 on keyboard panel 2,
A numerical value corresponding to page selection switch 4 is applied from page designation circuit 109 to arithmetic circuit 106, latch circuit 108, and motor control circuit 110. The latch circuit 108 temporarily stores the numerical value, and the arithmetic circuit 106 subtracts a certain numerical value from the given numerical value, obtains a page signal several pages before the page of the item sheet to be selected, and stores it in the latch circuit 105. On the other hand, the motor control circuit 110 rotates the motor in response to the designated multiple number given from the page designation circuit 109, and controls the driving pulley 57, the timing belt 56, and the pulley 11.
Rotating drum 5 is rotated via J55. As the rotating drum 5 rotates, the rotating disk 91 also rotates, and the light receiving element 94 detects the light given from the light emitting element through the through hole 92, and generates the reference signal shown in FIG. 6a. This reference signal is waveform-shaped by a shaping circuit 103 and is applied to a counter 100 as a counting means. Thereby, the counter 100 is reset. On the other hand, the light receiving element 9
5 detects the light given from the light emitting elements through the through holes 911 to 91m of the rotating disk 91 and generates a timing signal (FIG. 6b).

This timing signal is waveform-shaped by the shaping circuit 102 and is applied to the counter 100 and one input terminal of the AND gate 112. Counter 100 counts the timing pulses. Then, the comparison circuit 104
, 107. Comparison circuit 104 compares the count value of counter 100 with a value temporarily stored in latch circuit 105 several pages before the page to be selected. When the count value of the counter 100 and the value of the latch circuit 105 match, a command signal is given to the motor control circuit 110 to rotate the motor at a low speed. That is, when selecting, for example, the item sheet 412 from among the item sheets 40 wound around the rotating drum 5, when the item sheet 412 approaches the guide parts 81 and 82, the motor is rotated at a low speed and the item sheet 412 is selected. The light receiving element 812 of the guide part 81
Make it easy to detect. Furthermore, the comparison circuit 107 compares the counted value of the counter 100 with the page number of the item sheet to be selected, which is temporarily stored in the latch circuit 108.

When the comparison circuit 107 determines that the count value of the counter 100 and the page number of the latch circuit 108 match, the item sheet 412 to be selected is close to the guide portions 81 and 82, and subtitle identification indicating that the item sheet 412 to be selected is close to the guide portions 81 and 82 is performed. AND gate 11
Give to 2. As a result, AND gate 112 is opened, and a timing signal is applied from shaping circuit 102 to flip-flop 111 to set it. Since the flip-flop 111 is set, the set output signal becomes A.
The terminal end of the item sheet 412 to be applied to the ND gate 113 to open the gate 0 comes into contact with the guide part 81,
At this time, the light emitted from the light emitting element 811 is reflected by the item sheet 412, and the light receiving element 812 detects the reflected light.

This detection output (FIG. 6 d) is applied to a shaping circuit 101 for waveform shaping, and is applied to a motor control circuit 110 via an AND gate 113. As a result, the motor control circuit 110 temporarily stops the motor and immediately rotates it in the opposite direction. As the motor rotates in the opposite direction, the rotating drum 5 rotates counterclockwise in FIG. As a result, the item sheet 412 that has come into contact with the guide section 81 is guided to the subtitle mounting section 28 through the gap between the guide sections 81 and 82. Note that when the selected item sheet 412 is completely loaded in the subtitle loading unit 28, the item sheet 41
Alternatively, the motor may be stopped by detecting the end of 2.

Further, in the above embodiment, the subtitle page is designated by the page selection switch 4, but a page designation symbol may be given to the page designation circuit 109 from the central processing unit.

That is, when an arbitrary program is selected from a plurality of programs and the central processing unit executes the program, the central processing unit gives the page designation code of the subtitle corresponding to that program to the page designation circuit 109. Do it like this. Further, in the above-described embodiment, when an item sheet is designated, the latch circuit 10
8 and stored in the counter 100 by the comparator circuit 107.
The count value of the latch circuit 108 is compared with the value of the latch circuit 108, and when they match, a subtitle identification signal is generated and the flip-flop 111
However, the comparator circuit 107 and the latch circuit 108 are not provided, the counter 100 is a down counter with a preset function, and the page selection switch 4
When operating , the numerical value of the page to be selected is preset in the down counter, the down counter is subtracted every time a timing pulse is given, and when the counted value of the down counter reaches a predetermined value, for example O, a subtitle identification signal is sent. may be generated.

As described above, according to the present invention, a reference number and a timing pulse are generated according to the rotation of the rotating drum, and a value corresponding to the number of pages of the item sheet to be selected after the reference number is given. When a timing pulse equal to An item sheet can be selected accurately and the item sheet can be surely displayed in a subtitle display section.
