Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-item information input device that selects and inputs multiple items of information into an information processing device through key operations.

Conventionally, multi-item information input devices can be roughly divided into two types.
There was one method. One method is to wind up a sheet with a plurality of items written on it into a roll, and the other method is to bind a sheet with a plurality of items written on it like a book. The former method is a method in which two rolls for winding up the sheet are provided in parallel at both ends of the lower surface of the key operation section, and the sheet is moved between the rolls to display the sheet on the key operation section. This method has disadvantages in that as the number of information items increases, the total length of the sheet increases, it takes a long time to wind up the roll when selecting information, and it is not possible to easily replace the sheet. On the other hand, in the latter method, information items are written on sheets of a certain size, and the sheets for each item are bound like a book. This method is cumbersome as the user has to flip through the pages like a book to select each item.

The present invention eliminates these drawbacks and
To easily and quickly select any sheet among a plurality of sheets, and to make the sheet storage part into a compact cartridge, which can be easily replaced. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on drawings showing one embodiment. First, before giving a detailed explanation, the basic operation of the input device according to the present invention will be described. Basic operations are shown in Figures 1 and 2, where 1 indicates multiple input items 12 (see Figure 6).
A plurality of sheets with the following information written on them are stored in a stacked state in the sheet tray 2. In the sheet separating section 5, among the sheets 1 in the sheet tray 2, all the sheets 1 located above an arbitrary sheet 1' are fixed by the sheet fixing means 3, and the arbitrary sheets 1' and the sheets located below it are fixed by the sheet fixing means 3. All the sheets 1 are moved by the sheet tray 2 in the direction of arrow A, and an arbitrary sheet 1' is displayed on the sheet display section 6. In addition, a method for selecting an arbitrary sheet 1' from among a plurality of sheets 1 in a stacked state is as shown in FIG. The sheet fixing means 3 facing the respective notches 7 are selected and fixed by the notches 7 (see FIG. 6).

The above is the basic operation of the input device according to the present invention. The multi-item information input device of the present invention will be explained in detail below. This device includes a sheet tray 2 that stores a plurality of sheets 1 on which a plurality of input items are written in a stacked state, a moving means 8 that moves the sheet tray 2 between a sheet display section 6 and a sheet separation section 5, and a plurality of sheets. 1, a key operation section 10 for inputting information to the information processing device, and a main body 11. A plurality of sheets 1 on which a plurality of input items 12 are written are stored in a sheet tray 2 in a stacked state to form a cassette. The sheet tray 2 is detachably supported by a slider 13 in order to move between the sheet display section 6 and the sheet separation section 5, and the slider 13 is fixed to a roller 14 having a V-groove.
It engages with a sliding bed 15 having a V-shaped protrusion. Further, the sliding bed 15 is fixed to a base 29 and serves as a reference fixing base for the sheet tray 2. The slider 13 is engaged by a pin 17 to the drive arm 16 for sliding;
The other end of the drive arm 16 engages with a shaft 18 fixed to the base 29, and the drive arm 1 is rotated by rotation of a triangular cam 19 provided in the middle of the drive arm 16.
6 is rocking. This rocking causes the slider 13 to slide along the sliding bed 15. Further, the triangular cam 19 is fixed to a rotary table 21 having a worm wheel 20, and the worm wheel 20 engages with a worm 23 connected to a motor 22 to transfer the power of the motor 22 to the worm 2.

Further, the rotating table 21 is provided with a cam surface 24, and a rotating roller 27 rotatably supported by a shaft 26 is in contact with one end of an arm 25 for operating the sheet selecting means 9.
Note that the rotation shaft 28 of the arm 25 is fixed to the base 43. The operation of this arm 25 in the seat selection means 9 will be described later. Further, the drive arm 16 engaged with the slider 13 is arranged so that the slider 13 is at the lower limit of the sheet display section 6 and at the sheet separation section 5.
When the drive arm 16 is located at the two upper limit positions, the power transmission from the triangular cam 19 to the drive arm 16 becomes 0 during the rotation angle of the rotary table 21 of 60 degrees, and the slider 13 remains stationary. While the slider 13 is stationary, the rotation of the motor 22 is stopped in the sheet display section 6, and the sheet 1 is selected in the sheet separation section 5. These operations will also be described later.

Next, the configuration of the sheet separating section 5 will be described. As described in the basic operation, the sheet separating section 5 fixes all the sheets 1 located above an arbitrary sheet 1' among the plurality of stacked sheets 1 by the sheet fixing means 3, and transfers them to the sheet tray 2. An arbitrary sheet 1' is placed on top within the sheet. Reference numeral 30 denotes a plurality of sheet fixing plates provided opposite to the notch portions 7 provided in the end surfaces of each sheet 1 of the plurality of sheets 1, whereby the sheet 1 located above any sheet 1' is fixed. The entire structure is fixed between the sheet holding plate 31 and the sheet holding plate 31. The sheet pressing plate 31 constantly applies downward force by the spring 32. Further, as described in the basic operation, the sheet fixing plates 30 move up and down in pairs symmetrically with respect to the sheet 1, and have cutout portions 7 provided in a stepped manner on the end surface of each sheet 1 of the stacked sheets 1. Sheet 1 located on the top surface
The center of the notch 7 is pressed. In the explanation of the basic operation, the sheet fixing means 3 refers to the sheet fixing plate 30 and the sheet pressing plate 31.
This shows that. An inclined long hole 36 is provided on the lower side of the seat fixing plate 30, and a logic board provided in this long hole 36 for selecting a pair of seat fixing plates 30 from among the plurality of seat fixing plates 30 is provided. The logic backing plate 34 is placed in contact with the pin 3.
5. Logic backing plate 34
Both ends are supported by comb-shaped guides 37 and 38, and are slidable. Comb-shaped guide 38
is fixed to the base 43. Further, a long hole 39 is provided on the upper side of the seat fixing plate 30, and a long shaft 40 is engaged with the long hole 39. Further, the upper end of the sheet fixing plate 30 is connected to the end surface of the comb-shaped guide 38 by a spring 41 to apply a downward force. Further, the upper side of the sheet fixing plate 30 is provided with a comb-shaped guide plate 42 to prevent lateral vibration when the sheet 1 is pushed up. The guide 37 of the logic backing plate 34 is fixed to this guide plate 42, and the base 43
A gap is provided between the sheet fixing plate 30 and the sheet fixing plate 30, and a lifting plate 44 is inserted into the gap. Note that the guide plate 42 is fixed to a base 43. Next, multiple seat fixing plates 3
The logic board 33 that selects one pair of seat fixing boards 30 from 0 will be described. The logic board 33 is made up of a combination of a plurality of boards. Each logic board 33 has a recess 45 having a different pattern, and is housed in a logic board guide 46 so as to be slidable in the longitudinal direction. This logic board 3
3 by the plunger 47 to select the seat fixing plate 30. The process of selecting the sheet fixing plate 30 will be explained with reference to FIGS. 7 and 8. Selection of the sheet fixing plate 30 described here means bringing any one of the plurality of sheet fixing plates 30 into contact with the lift-up plate 44 provided for pushing up the seat 1. First, a plurality of seat fixing plates 30 are lined up as shown in solid lines and the lifting plate 4 is
4 is in a state where it is not in contact. In this state, only the logic plate 33 whose end face is in contact with the convex portion 48 has a plunger 47 with a constant dimension.
When the seat fixing plate 30 is slid to align with the recess 45 by the tension force of the spring 41, the seat fixing plate 30 attempts to rotate about the long axis 40 in the direction of arrow B in FIGS. 6 and 8. Because of this, the logic backing plate 34
is the logic board 3 in the direction of arrow C in Figures 7 and 8.
3, and the seat fixing plate 30 is rotated in the direction of the arrow B. The sliding movement of the logic plate 33 will be described with reference to FIG. For example, in order to move the logic abutting plate 34 of a in the direction of arrow C, it is sufficient to slide the logic plates 33, 33 of a and d using the plunger 47. Also, if it is the logic backing plate 34 of b, then the logic plates 33, 33 of c and e
All you have to do is slide it using the plunger 47. When the seat fixing plate 30 rotates, it becomes the state shown by the two-dot chain line, and then the seat fixing plate 30 is raised by lifting the lift-up plate 44. Note that the other sheet fixing plates 30 are not lifted up because their end faces are off from the lifting plates 44. Furthermore, since the plunger 47 is fixed to the base 43 so that the suction force acts in a direction perpendicular to the sliding direction of the logic board 33, the arm 52 rotates around a pin 51 fixed to the base 43.
The direction of the force is changed by Note that the plunger 47 is returned to its original position by a spring 50.
Next, the configuration and operation of the lift plate 44 will be explained with reference to FIG. Note that FIG. 9 shows the state at the time of sheet selection. A recess 53 is formed at both ends of the lift plate 44, and a pinion cam 55 having a tooth surface 54 is inserted into the recess 53.
The cam surface 56 pushes up the recess 53 due to the rotation of
The seat fixing plate 30 that is in contact with is raised.
The pinion cam 55 rotates when the tooth surfaces 54 engage with racks 58 formed at both ends of a rack plate 57 provided parallel to the raised plate 44, and as the rack plate 57 slides. It is. The sliding of the rack plate 57 is achieved by engaging one end of the arm 25 which swings in contact with the cam surface 24 of the rotary table 21 via the pin 59 in the moving means 8 described above. It slides by the oscillation of the The lift plate 44 and the rack plate 57 are locked to a guide 60 (see FIGS. 4 and 5), so that the lift plate 44 is fixed in the vertical direction, and the rack plate 5
7 is restricted in movement only in the longitudinal direction. Further, a spring 61 is provided on one end surface of the rack plate 57 for pressing the rotating roller 27 provided on the arm 25 against the cam surface 24. Furthermore, easy board 57
A pawl 62 is provided at the bottom of the sheet, and an arm 64 is engaged with this pawl 62 to drive a push plate 63 for separating the logic backing plate 34 from the logic plate 33 after sheet selection. The arm 64 rotates around the rack plate 5 around a shaft 65 fixed to the base 43.
It rotates by the sliding motion of 7. The arm 64 and the push plate 63 are engaged with each other by a pin 66. Further, the base 29 and the base 43 are connected and fixed by a fixing pin 67, so that the moving means 8 and the sheet selecting means 9 can be separated. Further, a switch 68 fixed to the base 29 detects the completion of sheet selection. Furthermore, a plurality of key switches 69 are arranged in parallel on the key operation unit 10 to select input items 12 written on any displayed sheet 1'.

Next, the overall operation will be explained. First, the operation from a state where an arbitrary sheet 1' among the plurality of sheets 1 is displayed on the sheet display section 6 and stopped will be described.
A necessary sheet 1 is inputted from among a plurality of sheets 1 using the key operation section 10. This input causes the motor 22 to start rotating, and the rotation of the worm 23 is transmitted to the worm wheel 20, causing the triangular cam 19 fixed to the rotary table 21 to rotate. At the same time, the plunger 47 engaged with the logic plate 33 via the arm 52 selectively operates, and the logic plate 3
3 to make it possible to select the sheet fixing plate 30 facing the upper sheet 1 of the required sheet 1. When the triangular cam 19 starts rotating, the drive arm 1
6 rotates, the slider 13 engaged with the drive arm 16 begins to move toward the sheet separating section 5, and the sheet tray 2 supported by the slider 13 removes any sheet 1' and all the sheets 1 located below it. It is moved to the sheet separating section 5. Next, when the triangular cam 19 rotates and the drive arm 16 starts to come to rest at the upper limit of the sheet separating section 5, the arm 25 is inserted into the recess 24' of the cam surface 24 provided on the rotary table 21 to which the triangular cam 19 is fixed. The rotating roller 27 begins to move in, and the rack plate 57, being tensioned by the spring 61, begins to slide in the direction of arrow D in FIG.
As the rack plate 57 slides, the pinion cam 55 engaged with the rack 58 of the rack plate 57 rotates, causing the lift plate 44 in contact with the cam surface 56 to be lowered. The sheet fixing plate 30, which fixes the sheet 1 on the upper side of any sheet 1' that has been pushed up, is lowered by the tensile force of the spring 41 as the lifter plate 44 is lowered.
In this lowered state of the seat fixing plate 30, the logic abutting plate 34 engaged therewith hits the convex portion 48 of the logic plate 33, so that the seat fixing plate 30 is in a state along the elongated holes 36 and 39 engaged with the long axis 40 and the pin 35, respectively. It descends while rotating. This state shows the state in which the sheet fixing plate 30 indicated by the dashed line shown in FIG. 8 returns to the seat fixing plate 30 indicated by the solid line. Further, as the sheet fixing plate 30 is lowered, all the sheets 1 located above the arbitrary sheet 1' are lowered together with the presser plate 31, so that the sheets 1 are stacked in the sheet tray 2. Next, when the rack plate 57 slides, the arm 64 of the push plate 63 engaged with the rack plate 57 rotates, causing the push plate 63 to retreat. When the push plate 63 retreats, the plurality of logic abutting plates 34, which have been separated from the logic plate 33, come into contact with the tip of the logic plate 33. Sheet 1 above sheet 1 required at this time
The logic abutting plate 34 engaged with the seat fixing plate 30 facing the seat enters into the recess 45 of the logic plate 33 in the selected state mentioned above, rotates the seat fixing plate 30, and lifts up the upper part of the plate 44. to be located. This state is the seat fixing plate 30 shown by the two-dot chain line in FIG. During this time, triangular cam 1
9 continues to rotate, and when the stationary state of the sheet tray 2 in the sheet separating section 5 approaches the end, the rotating roller 27 of the arm 25 enters the end of the recess 24' of the cam surface 24 provided on the rotating table 21. Initially, the arm 25 begins to rotate along the recess 24' of the cam surface 24. When the arm 25 rotates, the rack plate 57 slides in the direction of arrow H in FIG.
6 pushes up and raises the kick-up plate 44. As the lift plate 44 rises, the sheet fixing plate 30 facing the sheet 1 above the required sheet 1 rises.
All of the sheets 1 located above the required sheet 1 are sandwiched and fixed with a presser plate 31. Furthermore, the sliding of the rack plate 57 causes the arm 64 to rotate, and the push plate 63 is advanced to separate the logic backing plate 34 from the logic plate 33 so as not to cause sliding resistance of the logic plate 33 when selecting the next sheet. . At this point, the recess 24' of the cam surface 24 provided on the rotary table 21
The rotating roller 27 of the arm 25 escapes, and at the same time, the drive arm 16 completes its stationary state in the sheet separating section 5 and begins to rotate toward the sheet display section 6. Along with this, the sheet tray 2 supported by the slider 13 stores the required sheet 1 and all the sheets 1 located below it and begins to move to the sheet display section 6. Next, when the triangular cam 19 rotates and the drive arm 16 enters the stationary state at the lower limit of the seat display section 6, the switch 68 operates to turn off the entire energization (plunger 47, motor 22) and stop the rotation of the motor 22. make it stop. Through the above-described operations, a necessary item is selected by the key switch 69 from among the plurality of items 12 written on the necessary sheet 1 displayed on the bottom surface of the key operation unit 10, and inputted to the information processing device. .

The multi-item information input device of the present invention can be implemented as described above, and the sheet storage section stores a plurality of sheets on which a plurality of items are written in a stacked state in a sheet tray. can be made into a thin and compact cassette, and the seat storage section can be easily replaced. Furthermore, since a plurality of sheets are stored in a stacked state in the sheet tray, it is also very easy to replace just one sheet. Further, the sheet selection operation of the present invention is such that a thin sheet tray is moved in a flat state, and a plurality of sheets is moved by a notch provided for each sheet and a sheet fixing means opposite to the notch. Since it is designed to be fixed in place, it is mechanically simple and can be operated reliably. Further, the reciprocating movement of the sheet tray can be achieved by uncontrolled rotation of one motor in one direction, and the overall mechanism is simple and can be made extremely thin. Furthermore, even if there are many sheets with multiple items filled in, as is clear from the first embodiment, the sheet selection time can be reduced simply by moving the sheet storage section of the cassette sheet tray back and forth in a plane. is very short. In addition, since multiple sheets with multiple items written on them are stored in a stacked state in the sheet tray, sheets can be randomly selected in the same short time. The present invention provides a multi-item information input device that has many advantages as described above.
