Description

Detailed Description of the Invention The present invention provides a method for selecting a desired sheet from among a plurality of sheets on which items are written in a multi-item information input device for inputting information on multiple items to an information processing device by key operation. The present invention relates to a sheet selection and feeding device for feeding.

Conventional multi-item information input devices include one in which a sheet on which items are roughly divided and filled in is bound into a notebook shape, and one in which the sheet is in a roll shape.

In the former method, holes are bored in the sheet of each page in a grid pattern, and light emitting elements protrude from each hole, and items are written in the vicinity of the holes. Then, input was made by placing a light pen on the light emitting element corresponding to the desired item.

On the other hand, in the latter method, a sheet with items written on it is wound into a roll, a glass plate with an electrode plate printed on it is placed on a flat part between two axes, and the sheet is moved by a motor. When the area where the necessary items are written is located on the flat part, the electrode plate corresponding to the desired item is pressed with a finger to input the information.

Therefore, in the former method, the user has to manually turn over the sheets in order to select the sheet on which the desired item is written. The latter method does not have this trouble, but as the number of entries increases and the total length of the sheet becomes longer, it takes more time to select the part with the desired entry and position it between the two axes. However, there were drawbacks such as the roll itself being difficult to replace.

In the present invention, a plurality of flexible sheets are wound in the same direction inside a sheet storage section, and an endless belt is used to press the outer periphery of the wound sheet tube into contact with the remaining part in the circumferential direction. The sheet cylinder is held in a rolled state and stored, and a separation plate is provided near a part of the outer cylinder of the sheet cylinder to separate the first sheet from other sheets, and the rotation axis of the sheet cylinder is rotated in both directions. To provide a sheet selection and feeding device which selectively feeds out one sheet to be selected separately from other sheets.

The present invention will be specifically explained below with reference to illustrated embodiments.

FIG. 1 is a plan view of the multi-item input device. That is, this device is broadly divided into a seat storage cartridge 1 that can be freely attached and detached from the outside and replaced;
It consists of a sheet deriving mechanism section 2 and an input operation section 3. As shown in FIGS. 1 and 2, the seat storage cartridge 1 has a rectangular casing 1a having a seat entrance and exit, and a rotating shaft 10 with one end protruding from a side plate 1a' of the casing 1a. It is rotatably attached, and the input operation section 3 is opened and inserted into the main body 5, and the input operation section 3 is installed in a predetermined position, or removed and replaced. In the installed state, as shown in FIG.
It is connected to the stepping motor 20 inside. Rotating axis 1
A slit disk 21 having a plurality of slits in the circumferential direction is attached to the extension of 0, and a light emitting element 22 and a light receiving element 23 are arranged facing each other on both sides of this slit disk 21. Board 2
1, a light emitting element 22 and a light receiving element 23 constitute a position detection device. Further, a belt 24 for holding most of the sheets 4'' drawn out from the seat storage cartridge 1 is connected to the rotating shaft 10 via gears and pulleys as appropriate.

The seat storage cartridge 1 is shown in Figures 2 and 3.
As shown in the figure, a plurality of flexible sheets 4 on which a plurality of arbitrary items are written are stored in a wound form with one end fixed at regular intervals on the same circumference.

FIG. 3 shows the internal structure of the sheet storage cartridge in detail. Two winding frames 11 and 12 are fixed to the rotating shaft 10, and one winding frame 11 has a plurality of winding frames 11 and 12 fixed to the rotating shaft 10. Holes 11a are formed at equal intervals, and grooves 12a parallel to the rotating shaft 10 are formed in the circumferential portion of the other winding frame 12 so as to face the holes 11a. A coil spring 1 is installed on the outside of the winding frame 12.
A holder 13 is loosely fitted into the holder 13, which presses the winding frame 11 in the direction of the winding frame 11 by receiving a force of
a is formed. Place seat 4 in seat storage section 1
To store the holder 13 against the coil spring 14 on the side opposite to the winding frame 12,
In this state, a rod-shaped stopper part 4 that is slightly longer than the width of the seat 4 is attached to one end side (terminal end) of the seat 4.
Insert one end of a into the hole 11a of the winding frame 11, pass the other end through the groove 14a of the holder 13, and insert the other end into the groove 12 of the winding frame 12.
Insert it into a. After performing this insertion operation for all the sheets 4, when the holder 13 is released, the holder 13 presses the winding frame 12 by the coil spring 14, so that from now on, the sheet 4 is inserted into the winding frame 12.
1 and 12.

The sheet 4 attached to the winding frames 11 and 12 in this way is wound in one direction, and as shown in FIG.
An endless belt 17 that is rotatably spanned over d.
It is held so that a part is exposed. However, among the rollers 16a to 16d, 16a to 16c
are provided directly on the side plate 15, but only 16d is attached to a rotating lever 18 connected to a roller 16a. Further, a spring 19 for applying tension to the belt 17 is attached to the roller 16a.

Note that the main body 5 has a detection function for detecting that the seat storage section 1 is attached to the main body 5 and further determining what classification item is written on the sheet 4 in the seat storage section 1. A device 6 is provided.

By operating the sheet selection push button of the input operation section 3, the desired sheet 4 is separately fed out onto the lower surface of the item selection push button of the input operation section 3.

In addition to the constituent elements 20 to 24 shown in FIG. 1, the sheet delivery mechanism section 2 also handles any one sheet out of the sheets 4 drawn out from the sheet storage cartridge 1 as shown in FIG. A separating plate 25 for separating and taking out the sheets 4', and a guide plate 26 for guiding and holding the separated and taken out sheets 4' below the input operation section 3.

In order to feed out the desired sheet to be selected below the input operation section 3, it is necessary to memorize the position of the sheet 4 mounted on the winding frames 11 and 12, counting from the sheet 4' as a reference. and a control circuit (not shown) that controls the drive of the stepping motor 20 when the seat selection push button is pressed.

Next, the operation of the sheet selection and feeding device described above will be explained. First, the seat storage cartridge 1 is inserted into the main body 5 by opening the input operation section 3, and is attached to a predetermined position, and the end of the rotating shaft 10 is connected to the stepping motor 20. At this time, the bottom plate 1a'' of the casing 1a of the seat storage cartridge 1 presses the detection device 6. As a result, the detection device 6 operates to detect that the seat storage cartridge 1 is attached. The detection device detects the rotational position of the rotation shaft 10 of the sheet storage cartridge 1 through the slit of the slit disk 21.

When a desired sheet is specified by pressing the sheet selection pushbutton on the input operation unit 3, the control circuit reads the relative position of the sheet to be selected from the reference sheet from the memory circuit, and reads out the relative position of the sheet to be selected from the reference sheet and uses the rotational position signal from the position detection device. The stepping motor 20 is rotated by the necessary number of steps in the direction opposite to the winding direction of the sheet.

After the free end of the sheet to be selected is positioned on the separating plate 25 in this way, the stepping motor 20 is reversed so that the rotating shaft 10 is rotated in the same direction as the winding direction of the sheet.
The selected sheet is separated and guided below the input operation section 3 by the guide plate 26. Also, the other seat 4'' has belt 2
4. You will be guided above. This state is shown in FIG. 2b.
During this rotation, the endless belt 17 rotates in circulation due to the frictional force with the seat 4.

Next time you try to select another sheet,
When the sheet selection push button on the input operation section 3 is pressed, the sheet is moved to the winding frames 11 and 1 by the operation of the stepping motor.
2, the position of the reference sheet 4' is similarly detected, and the rotation of the stepping motor 20 advances from this position by the number of steps corresponding to the sheet to be selected. Next, step motor 2
0 rotates in the direction of arrow A', the selected sheet is separated and guided onto the guide plate 26 in the same manner as described above.

As above, any sheet can be input to the input operation section 3.
When the user is guided to the bottom of the sheet, the user presses an input key corresponding to an arbitrary item written on the sheet. As a result, information on the item corresponding to the input key 37 is input to the information processing device.

As explained above, in the present invention, a large number of sheets are wrapped in a cylindrical shape, and only a part of the outer periphery is excluded, and an endless belt that can rotate along the circumference is used to press the sheet.
The position of the free end of the sheet on the separation plate provided near the part that is not pressed is detected, and the stepper motor 20 rotates the rotary shaft 10 by the required number of steps to feed the sheet, allowing quick and accurate sheet feeding control. Furthermore, since the sheet storage cartridge is detachable and replaceable, many types of sheets can be fed out as desired by replacing the cartridge with a type suitable for the purpose.
