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 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. Hereinafter, the present invention will be explained based on illustrated embodiments. First, before giving a detailed explanation, the basic operation of the multi-item information input device according to the present invention will be described. In Figures 1 and 2, 1

Next, the logic board 33 for selecting a pair of seat fixing plates 30 from among the plurality of seat fixing plates 30 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 plate 33 is slid by a 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 sheet fixing plates 30 are lined up as shown by solid lines, and are not in contact with the lifting plate 44. In this state, if only the logic plate 33 whose end surface is in contact with the convex part 48 is slid by the plunger 47 of a certain dimension to match the concave part 45, the tension force of the spring 41 will cause the logic plate 33 to be seated.

When the seat fixing plate 30 rotates, it becomes in the state shown by the two-dot chain line, and then the seat fixing plate 30 is raised by lifting the kick-up plate 44. Note that the other seat fixing plate 30 is the lift-up plate 4.
Since the end face is off from 4, it cannot be raised. In addition, the plunger 47 is connected to the logic board 33.
Since it is fixed to the base 43 so that the suction force acts in a direction perpendicular to the sliding direction, the direction of the force is changed by the arm 52 that rotates around a pin 51 fixed to the base 43. ing. In addition, plunger 4
7 is restored 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. There are recesses 53 at both ends of the kick-up plate 44.
A pinion cam 55 having a tooth surface 54 is inserted into this recess 53, and as the pinion cam 55 rotates, the cam surface 56 pushes up the recess 53, lifting the kick-up plate 44, and raising the lift-up plate. 44 is raised. The rotation of this pinion cam 55 is caused by the lifting plate 4
The tooth surface 54 engages with racks 58 formed at both ends of a rack plate 57 provided in parallel with the rack plate 57, and rotates as the rack plate 57 slides. 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 a pin 59 in the moving means 8 described above. It slides by the oscillation of 25. In addition, the kick-up board 44
The rack plate 57 is locked by a guide 60 (see FIGS. 4 and 5), so that the lift plate 44 is restricted from moving only in the vertical direction, and the rack plate 57 is restricted from moving only in the longitudinal direction. Further, on one end surface of the rack plate 57, a rotating roller 27 provided on the arm 25 is connected to a cam surface 24.
A spring 61 is provided to press the spring. Furthermore, a claw 62 is provided at the bottom of the rack plate 57.
This claw 62 is a push plate 63 for separating the logic backing plate 34 from the logic plate 33 after selecting the sheet.
An arm 64 is engaged to drive the. The arm 64 is rotated about a shaft 65 fixed to the base 43 by sliding of the rack plate 57. The arm 64 and the push plate 63 are engaged 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. Also, base 2
A switch 68 fixed at 9 detects 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 of this embodiment 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 desired sheet 1 is input from among the plurality of sheets 1 using the key operation unit 10. The motor 22 starts rotating due to this input, and the worm 2
3 is transmitted to the worm wheel 20, and the triangular cam 19 fixed to the rotary table 21 rotates. At the same time, the plunger 47 engaged with the logic plate 33 via the arm 52 selectively operates to slide the logic plate 33 to select the sheet fixing plate 30 facing the upper sheet 1 of the required sheet 1. state. When the triangular cam 19 begins to rotate, the drive arm 16 rotates, and the slider 13 engaged with the drive arm 16 begins to move toward the sheet separating section 5.
The sheet tray 2 supported by the slider 13 is arranged between an arbitrary sheet 1' and a sheet 1 located below it.
All the sheets are 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. rotating roller 2
7 begins to enter, and the rack plate 57 begins to slide in the direction of arrow D in FIG. 5 because it is being pulled by the spring 61. Pinion cam 5 engaged with rack 58 of rack plate 57 by sliding of rack plate 57
Reference numeral 5 denotes a sheet fixing plate which rotates to lower the lift plate 44 in contact with the cam surface 56 and fixes the sheet 1 above any sheet 1' pushed up by the lift plate 44. 30 is lowered by the tensile force of the spring 41 as the lift 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 moved along the elongated holes 36 and 39 engaged with the long axis 40 and the pin 35, respectively. It descends while rotating in a hanging state. This state is the 8th
The figure shows a state in which the seat fixing plate 30 indicated by the chain line returns to the position 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, and the sheets 1 are stacked in the sheet tray 2. Next, when the rack plate 57 slides, the rack plate 57
The arm 64 of the push plate 63 engaged with the push plate 7 rotates, causing the push plate 63 to retreat. When the push plate 63 retreats, the plurality of logic backing plates 34 that were separated from the logic board 33 are moved back to the logic board 3.
It hits the tip of 3. At this time, the logic backing plate 34 engaged with the sheet fixing plate 30 facing the sheet 1 on the upper side of the required sheet 1 enters the recess 45 of the logic plate 33 in the selected state mentioned above, and the sheet fixing plate 30 Rotate and position it above the lift plate 44. This state is the seat fixing plate 30 shown in chain lines in FIG. During this time, the rotation of the triangular cam 19 continues, and the sheet separating section 5
When the stationary state of the sheet tray 2 approaches the end, the recess 24' of the cam surface 24 provided on the rotary table 21
The rotating roller 27 of the arm 25 begins to enter the terminal end of the arm 25, and the arm 25 moves along the recess 24' of the cam surface 24.
begins to rotate. When the arm 25 rotates, the rack plate 57 slides in the direction of arrow H in FIG.
3 is pushed up by the cam surface 56, and the kick-up plate 44 is raised. The sheet fixing plate 30 faces the upper sheet 1 of the required sheet 1 due to the lifting of the lifting plate 44.
is raised, and all of the sheets 1 located above the required sheet 1 are sandwiched between the presser plate 31 and fixed. Furthermore, the arm 64 rotates due to the sliding of the rack plate 57, and the pushing plate 63 is moved forward to push the logic backing plate 3.
4 is separated from the logic board 33 so as not to cause sliding resistance of the logic board 33 when selecting the next sheet. At this point, the cam surface 2 provided on the rotary table 21
The rotary roller 27 of the arm 25 escapes from the recess 24' of No. 4, and at the same time, the drive arm 16 completes its stationary state in the sheet separation section 5 and begins to rotate toward the sheet display section 6. Along with this, the sheet tray 2 supported by the slider 13 is loaded with the necessary sheet 1.
Then, all the sheets 1 located below are stored, and the movement to the sheet display section 6 begins. 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 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. .

Next, another embodiment of the present invention will be described with reference to FIGS. 10, 11, and 12. 10th
As shown in FIG.
Two sets of a and 7b are provided in the direction of movement of the sheet, and
A sheet fixing plate switching means is provided for switching the sheet fixing plate 30 to correspond to the two sets of sheet notches.

The seat fixing plate switching means is rotatably supported at the center by fixing members 70, 70', and
It includes a pair of switching levers 71, 71' with one end supporting the long shaft 40, and plungers 72, 72' engaged with the switching levers 71, 71'. In addition, the switching levers 71, 71' are operated by the spring 7.

On the other hand, when the plungers 72, 72' are energized, the switching levers 71, 71' are moved by the levers 73, 7.
71a, shown in dotted lines in FIG.
It is rotated to the position 71a', and the long axis 40 is
It is moved to position a. As a result, the 12th
As shown in the figure, the fixing plate 30 is rotated toward the center of the seat and is in the position shown at 30a.
In the same manner as in the previous embodiment, when the lifting plate 44 is lifted upward, the apex of the fixed plate is 30c.
As a result, the sheet group 1b belonging to the sheet notch 7b is selectively separated.

In FIG. 12, 30' is the plunger 7
2 and 72' are not energized, and the fixed plate 30 is lifted up by the lifting plate 44. That is, in this embodiment, it is possible to arbitrarily select twice as many sheets as in the previous embodiment without substantially increasing the number of fixing plates.

The multi-item information input device of the present invention can be implemented as described above, and the sheet storage section stores sheets on which a plurality of items are written in a stacked state in a sheet tray. The seat storage section 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.

In addition, by providing two sets of notches in the sheet and switching the sheet fixing plates to corresponding positions, it is possible to virtually select twice as many sheets as the number of fixing plates. This not only makes it easy to select the desired number of sheets, but also halves the number of fixing plates compared to the number of required sheets, which greatly simplifies the device.

Furthermore, 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 a large number of sheets with multiple items written on them, as is clear from the previous example, sheet selection is possible simply by moving the sheet storage section of the cassette sheet tray back and forth in a plane. time is very short. Furthermore, since a plurality of sheets with a plurality of items written on them are stored in a stacked state in a sheet tray, sheets can be randomly selected in the same short time.

As described above, the present invention provides a multi-item information input device that has many advantages as described above.
