Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a multi-item information input device, and particularly to a belt wrapping mechanism for wrapping a page sheet around a reversely rotatable winding shaft.

As a conventional device for inputting multiple items of information into an information processing device through key operations, there is a ``multi-item information input device'' filed by the present applicant on February 26, 1980. This is a device that consists of a page sheet member (input medium cartridge) storage section, a page sheet switching mechanism section, a keyboard section for input operations, etc. An input media cartridge having one end of the page sheet fixed to a flexible base sheet with one end of the page sheet spaced apart for a certain period of time is removably attached to the apparatus.

In such a multi-item information input device, the page sheet switching mechanism unit includes a winding shaft around which an input medium cartridge is wound, a belt for holding the wound input medium cartridge on the winding shaft, and a belt on which the belt is hung. Equipped with multiple rotating shafts,
The winding shaft rotates forward to wind up the cartridge, and
While the leading end of the selected page sheet is brought into contact with the guide plate for feeding out the page sheet, the desired page sheet is fed out to the keyboard section by reverse rotation of the winding shaft.

Therefore, the position of one of the plurality of belt passing rotation shafts is related to the role of bringing the leading end of a desired page sheet into contact with the guide for feeding out the page sheet.

In FIG. 3, the multi-item information input device 1 is a housing in which a base 2 on which a keyboard section and a page sheet switching mechanism section are mounted is covered with a lid 4 having a plurality of through holes 3 drilled in a matrix. It has a body structure, and an input medium cartridge exchange port 5 communicating with the inside of the casing is provided on the front surface.

In addition, a thin push button switch 6 is provided below each through hole 3, and is switched by the vertical movement of the key top. It is divided into an input key group B for inputting data.

In FIG. 4, which schematically shows the internal structure of the device 1, the base 2 covered with the lid 4 has a keyboard section 8 mounted with a push button switch 6 between the opposite side walls 7, only one of which is shown. A page sheet switching mechanism section 9 is arranged behind the page sheet switching mechanism section 9.

The keyboard section 8 has a pair of U-shaped cross-sectional metal fittings 81 sandwiched above and below, and a printed board 82 on which the push button switch 6 is mounted and a printed board 83 on which keyboard circuit components are mounted. Also, printed board 8
A guide plate 84 for guiding the key tops corresponding to the push button switches 6 is installed above the push button switch 2, and a guide plate 85 for guiding the input medium cartridge 10 is attached below the printed board 83. It is attached with a gap between it and the lid 4 for introducing the page sheet.

The page sheet switching mechanism section 9 is connected to the cartridge 1
A winding shaft 9 equipped with an engagement groove 91 on the circumferential surface around which 0 is wound.
2, a rotary shaft 93 connected to a pulse motor (not shown) for rotating the winding shaft 92, and an endless belt 94 for winding and holding the cartridge 10 around the winding shaft 92, which is connected to the shafts 92 and 93. It has axes 95-97.

Note that below the keyboard section 8, opposing and parallel guide plates 85 and 11 form a passage 14 for the cartridge 10, and a space connecting the winding shaft 92 and the guide plate 84 is used to store the selected page sheet. A guide plate 12 against which the leading end comes into contact and a guide plate 13 opposite to the guide plate 12 form a passage for the selected page sheet, and the passage 14 is connected to the cartridge exchange port 5 and the winding shaft 9.
It leads to 2.

In FIG. 5, the input medium cartridge 10 is composed of a plurality of page sheets 101 of the same shape made of flexible film, an opaque base sheet 102, and an engaging pin 103. The page sheet 101 has function display items for each push button switch 6 of the input key group B written on its surface, and the base sheet 102, which has a metal engagement pin 103 fixed to one end, has a hole 104 for cartridge identification. A hole 105 for base sheet detection is bored. And each page sheet 101
One end portion is fixed to the base sheet 102 parallel to the engagement pin 103 and at regular intervals.

In the device configured as described above, after inserting the cartridge 10 into the guide passage 14 through the exchange port 5 so that the engagement pin 103 comes into contact with the winding shaft 92, the selection key corresponding to the selected page sheet 101 is pressed. A predetermined switch 6 of group A is pressed down to cause the switch 6 to switch.

As a result, the cartridge 10 with the engaging pin 103 engaged with the groove 91 is wound around the rotating winding shaft 92, and as shown in FIG.
After the winding shaft 92 is rotated in the opposite direction, the selected page sheet 101 is brought out onto the guide plate 84, and a function display is displayed for each push button switch 6. The given and other page sheets 101 are stored in the passage 14, and the page selection operation is completed.

However, although the shafts 93 and 96 rotate at their installed positions, the shaft 97, which is constantly tensioned by the tension coil spring 98, can be moved in parallel to keep the tension of the belt 94 constant. Attach the shaft neck part 9 to the metal fitting 99
The rotating shaft 95 on which the rotating shaft 5a is supported is slidable along the slope 99a of the metal fitting 99 formed toward the center of rotation of the winding shaft 92.

[Problem that the invention attempts to solve]

In the multi-item information input device configured as described above,
The rotating shaft 95, which is constantly pulled rearward by the tension of the belt 94, is movable toward the center of rotation of the winding shaft 92 by its own weight and the tension of the belt 94.

Therefore, the thickness unevenness of the page sheet 101 itself, the thickness unevenness due to the function display writing method (handwriting, printing, label pasting, etc.), and the thickness unevenness of the page sheet 101
01 around the winding shaft 92, the position where the tip of the selected page sheet 101 leaves the elastic belt 94 remains constant. The feeding of the selected page sheet 101 is now more stable than that configured for rotary printing.

However, the cartridge 1 wound around the winding shaft 92
0 page sheet 101 has the number of pages, for example, the first page, the second page from the one closest to the engagement pin 103, etc., and when the interval between them is l, the winding diameter gradually increases with the number of pages. Since the leading edge shifts, the winding time interval of the leading edge of each page sheet is l+α,
They will be shifted in order as l+2α,...
Therefore, when environmental changes such as temperature are added to extreme variations in the thickness and looseness of the winding, the selected page sheet 101 cannot be smoothly fed out by the device.
A solution was desired.

[Means for solving problems]

The present invention, which aims to solve the above-mentioned problems, uses an input information cartridge, which is made up of a plurality of flexible page sheets on which input information is written, each end of which is fixed to a flexible base sheet at regular intervals. The other end of the wrapped page sheet of the cartridge among a plurality of rotating shafts around which belts are wrapped and rotated along the winding shaft within an appropriate angular range in order to be wound around the shaft and held. A rotating shaft provided at a position away from the belt circumferential portion is closer to the one rotating shaft than the rotation center of the winding shaft and is slidable toward a point inside the belt circumferential portion. This is a multi-item information input device characterized by being held in a.

[Effect]

According to the above means, the variation due to the winding diameter of the page sheet is corrected by making one of the plurality of belt passing rotating shafts slidable and the sliding direction being as described in the above means. Therefore, even if the thickness of the page sheet is extremely uneven or the winding is loose, and environmental changes occur, the operation of feeding the selected page sheet to the keyboard section is reliable.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

When the cartridge 10 is wound around the winding shaft 92, the selection point at which the leading edge (other end) of the selected page sheet leaves the rotating shaft 95 (to be precise, the belt 94) is determined by the rotation of the rotating shaft 95. This is the position where the straight line connecting the center and the rotation center of the winding shaft 92 intersects the page sheet.

Therefore, the selection point of the page sheet 101a is Pa,
Page sheet 101b and page sheet 101
Those in c are the positions indicated by Pb and Pc in the figure,
Selection point Pa is located in front (left side) of selection point Pb,
The selection point Pc is now located in front (to the left) of the selection point Pa.

As a result, the page sheet 1 generated by being wound outside the page sheet 101b.
01a tip misalignment and page sheet 101a
The displacement of the leading edge of the page sheet 101c caused by winding the page sheet 101c to the outside is offset by the movement of the selection point, and the selected page sheet is fed out stably and reliably.

[Effect of idea]

As explained above, according to the present invention, the selected page sheet can be fed out stably and reliably, and the reliability of the multi-item information input device is improved.
By using sheet materials with different thicknesses for the page sheet and the base sheet, the effect of making it possible to use cartridges that were previously incompatible is extremely significant.
