Description

[Detailed description of the invention]

The present invention relates to an operating device that selects and operates a desired output member from among a plurality of output members. Conventionally, when a plurality of output members are provided and a desired output member is selectively selected from them, a plunger or the like that converts electrical input into mechanical output is connected to each of the plurality of output members, and the plunger is selectively connected to the plurality of output members. The required output member was selected by energizing it. This method requires the same number of plungers as the output members, which causes many problems, such as the overall size and complicated structure. Furthermore, there were other problems such as the need for a large-capacity electrical power source in order to provide sufficient output for the plunger. The present invention eliminates these drawbacks and
It is possible to select a desired output member from among a plurality of output members with a simple configuration. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings showing an embodiment in which the present invention is applied to a sheet selection mechanism of a multi-item information input device. 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 5 that moves the sheet tray 2 between a sheet display section 3 and a sheet selection section 4, and a plurality of sheets. 1, and a sheet selection means 6 for selecting an arbitrary sheet 1' from among the sheets 1'. A plurality of sheets 1 on which a plurality of input items have been 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 7 for movement between the sheet display section 3 and the sheet selection section 4, and the slider 7 is fixed to a roller 8 and engaged with a sliding bed 9. Furthermore, the sliding bed 9 is fixed to a base 10. The slider 7 is engaged with one end of a drive arm 11 by a pin 12 for sliding, and the other end of the drive arm 11 is engaged with a shaft 13 fixed to the base 10;
Triangular cam 14 provided in the middle of drive arm 11
The rotation of the drive arm 11 causes the drive arm 11 to swing. This rocking causes the slider 7 to slide along the sliding bed 9. Furthermore, the triangular cam 14 has a worm wheel 15 and a cam surface 16.
The worm wheel 15 engages with a worm 19 connected to a motor 18, transmits the rotation of the motor 18 to the rotary table 17, and rotates the triangular cam 14. Also, turntable 1
An arm 20 for driving the sheet selection means 6 is engaged with the cam surface 16 at 7 via a rotating roller 23 so as to swing about a rotating shaft 22 fixed to a base 21. Further, when the slider 7 is located at the bottom dead center of the seat display section 3 and the top dead center of the seat selection section 4, the drive arm 11 engaged with the slider 7 receives power from the triangular cam 14 to the drive arm 11. The transmission is the rotation angle of the rotary table 17
Between 60 degrees, it becomes 0 and the slider 7 remains stationary.
During this time, the rotation of the motor 18 is stopped in the seat display section 3, and the seat 1 is selected in the seat selection section 4. Next, the configuration of the sheet selection means 6 will be described. First, the sheet selection section 4 performs the following operations. The entire upper sheet layer 24 above an arbitrary sheet 1' among the plural sheets 1 in a stacked state is lifted and separated and fixed, and placed in the sheet tray 2 with the arbitrary sheet 1' as the uppermost surface and the upper sheet layer 24 below it. The entire lower sheet layer 25 remains. FIG. 3 is a schematic perspective view of the main part of the sheet selection means 6. A plurality of sheets 1 are provided with stepwise notches 26 on their end faces starting from the lowest sheet 1. The sheet layer 24 above any sheet 1' is fixed between the sheet layer 24 and the sheet pressing plate 28 by a plurality of sheet fixing plates 27 provided opposite to the notch 26. The sheet pressing plate 28 is always pressed downward by a spring 29. Further, the seat fixing plates 27 move up and down as a pair symmetrically with respect to the seat 1, and fix the seat 1 in a stable state.
Next, the lower side of the seat fixing plate 27 has an inclined long hole 3.
0, and a logic detection plate 31 is engaged with this elongated hole 30 via a pin 32 in order to select a pair of sheet fixing plates 27 from among the plurality of sheet fixing plates 27. The logic detection plate 31 is supported by comb-shaped guides 33a and 33b at both ends and is slidable. Comb-shaped guide 33b
is fixed to the base 21. Further, the tip end 34 of the logic detection plate 31 is adapted to engage with a logic plate 35. On the other hand, a long hole 36 is also provided on the upper side of the seat fixing plate 27, and a long shaft 66 is engaged with the long hole 36. Furthermore, the upper end of the seat fixing plate 27 is attached to the spring 3.

Applying downward force. Also, the seat fixing plate 27
A comb-shaped guide plate 38 is provided on the upper side to prevent the fixed plate 27 from swinging laterally. The comb-shaped guide 33a and the long shaft 66 are fixed to this guide plate 38, and the guide plate 38 is fixed to the base 21. In addition, the comb-shaped guide 33a and the base 21
A lift plate 39 is provided in the gap between the sheet fixing plate 27 and the sheet fixing plate 27 in order to smooth the sheet lifting operation of the sheet fixing plate 27. Next, the logic board 35 for selecting a pair of sheet fixing plates 27 necessary for pushing up the upper sheet layer 24 from among the plurality of sheet fixing plates 27 will be described. The logic board 35 is made up of a combination of a plurality of boards. Each logic board 35 has a concave part 40 and a convex part 41 having different patterns, and is housed in a logic board guide 42 so as to be slidable in the longitudinal direction. This logic plate 35 is slid by a plunger 43 to select the seat fixing plate 27. The process of selecting the seat fixing plate 27 will be explained with reference to FIGS. 3 and 4. Selection of the seat fixing plates 27 described here means engaging a desired one from among the plurality of seat fixing plates 27 with the lifting plate 39 provided for pushing up the seat 1. First, a plurality of seat fixing plates 27 are lined up as shown by solid lines and are not engaged with the lifting plate 39. This is because the tip end 34 of the logic detection plate 31 is engaged with the protrusion 41 of one of the logic plates 35. In this state, only the logic plate 35 that is engaged with the protrusion 41 of the logic plate 35 is slid by the tip end 34 of the logic detection plate 31 that is engaged with the required sheet fixing plate 27 by the plunger 43 of a certain size. so that the recess 40 of the logic plate 35 is aligned with the tip 3 of the logic detection plate 31.
4, the seat fixing plate 27 is about to rotate about the long axis 66 in the direction of the arrow (a) in FIG. 4 due to the tensile force of the spring 37. The sheet fixing plate 27 is slid in the direction of the arrow (B) by the depth of the recess 40 of the logic plate 35, and the seat fixing plate 27 is rotated in the direction of the arrow (A) in FIG.
As a result, the required parts of the seat fixing plate 27 can be engaged with the kick-up plate 39 (the state shown by the two-dot chain line in FIG. 4). Also, another seat fixing plate 2
7 is designed such that the logic detection plate 31 is engaged with one of the convex portions 41 of the logic plate 35 and does not rotate. Here, the configuration and selection operation of the logic board 35 will be described with reference to FIG. FIG. 5 describes an example in which three logic boards 35 are used. If the operation combinations using three logic boards 35 are represented by 0 and 1, there are eight combinations as shown in the following table.

[Table] This combination is formed at approximately equal intervals on the end faces of the logic plates 35 shown in (A) to (c) as concave portions 40 (0) and convex portions 41 (1). are positioned at the centers (A) to (H) of the combination of the respective uneven portions 40 and 41. Also, uneven portions 40, 4 formed on each end surface.
1 is half the width of the interval between each logic detection plate 31,
The remaining half end face is assembled in a direction opposite to the sliding direction of the logic plate 35, and is assembled in a direction opposite to (A) to (H). 4
1' is formed. From this configuration, logic detection board 3
1, for example, to select the logic detection plate 31 of (B), the convex plate 41 of the logic plate 35 of (c) is engaged, and this logic plate 35 is
If the plunger 43 in (c) is used to slide half the distance between the logic detection plates 31, the convex portion 41 of the logic plate 35 in (c) will change to the concave portion 40, and the logic detection plate 31 in (B) will become a concave portion. Slide by a depth of 40 mm. On the other hand, since the plunger 43 is attached to the base 21 so as to act in a direction perpendicular to the sliding direction of the logic board 35, the direction of the force is controlled by the arm 47 which rotates around a pin 46 fixed to the base 21. is changing. Note that the plunger 43 is returned to its original position by a spring 48. Next, the structure and operation of the lift plate 39 will be described with reference to FIG. 6, which shows the state at the time of sheet selection. A recess 49 is formed at both ends of the lift plate 39, and a pinion cam 51 having a tooth surface 50 is inserted into the recess 49. As the pinion cam 51 rotates, the cam surface 52 pushes up the recess 49, thereby lifting the lift plate 39. The seat fixing plate 27 that has been raised and engaged with the kick-up plate 39 is raised. This rotation of the pinion cam 51 is caused by the tooth surfaces 50 engaging with racks 54 formed at both ends of a rack plate 53 provided parallel to the raised plate 39, and the pinion cam 51 being rotated by the sliding movement of the rack plate 53. be. Furthermore, this easy board 5
3, the arm 20 engages with the cam surface 16 of the rotary table 17 and swings in the moving means 5 described above.
A rack plate 53 is engaged with one end of the arm 20 via a pin 55, and slides as the arm 20 swings. The lift plate 39 and the rack plate 53 are locked by a guide 56 (see FIGS. 1 and 2), so that the lift plate 39 is restricted from moving only in the vertical direction, and the rack plate 53 is restricted from moving only in the longitudinal direction. Also, the rack board 53
A spring 57 for pressing the rotating roller 23 provided on the arm 20 against the cam surface 16 is provided on one end surface. Furthermore, a claw 5 is provided at the bottom of the rack plate 53.
8, and this pawl 58 is provided with an arm 60 for driving a push plate 59 for separating the logic detection plate 31 from the logic plate 35 after sheet selection.
is engaged. The arm 60 rotates about a shaft 61 fixed to the base 21 by sliding of the rack plate 53, and the arm 60 and the push plate 59 are engaged with each other by a pin 62. Also, the base 21 has a fixing pin 6
3, so that the moving means 5 and the sheet selecting means 6 can be separated. Further, a switch 64 fixed to the base 10 is used to detect completion of sheet selection. 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 3 and stopped will be described. Key operation section (not shown) from among multiple sheets 1
Perform more necessary input on Sheet 1. This input causes the motor 18 to rotate, the rotation of the worm 19 to be transmitted to the worm wheel 15, and the triangular cam 14 fixed to the rotary table 17 to rotate. At the same time, the plunger 43 engaged with the logic plate 35 via the arm 47 selectively operates to slide the logic plate 35 and bring the sheet fixing plate 27 into a state where it can select the desired seat 1. . When the triangular cam 14 begins to rotate, the drive arm 11 rotates, the slider 7 begins to slide toward the sheet selection section 4, and the sheet tray 2 supported by the slider 7 is moved to the bottom with an arbitrary sheet 1' as the top surface. Sheet layer 25
is moved to the sheet selection section 4. Next, when the drive arm 11 starts to come to rest at the top dead center of the sheet selection section 4, the cam surface 16 provided on the rotary table 17
The rotating roller 23 of the arm 20 begins to enter the recess 16', and the rack plate 53, being tensioned by the spring 57, begins to slide in the direction of the arrow (c) in FIG. As the rack plate 53 slides, the pinion cam 51 that is engaged with the rack 54 of the rack plate 53 rotates, and the raised plate 39 that is in contact with the cam surface 52 rotates.
is lowered, and the upper sheet layer 2 of any sheet 1' is lowered.
The seat fixing plate 27, which is pushing up the seat plate 4, is lowered by the tensile force of the spring 37 along with the lowering of the lifter plate 39. When the seat fixing plate 27 is in the lowered state, the tip 34 of the logic detection plate 31 engaged therewith hits the protrusion 41 of the logic plate 35, so that the elongated holes 36 and 3 engaged with the long shaft 66 and the pin 32, respectively.
It descends while rotating along 0. In this state, the seat fixing plate 27 indicated by a dashed line in FIG.
shows a state in which the sheet is returned to the seat fixing plate 27 indicated by a solid line. Further, as the sheet fixing plate 27 is lowered, the upper sheet layer 24 above any sheet 1' is lowered together with the presser plate 28, so that all the sheets 1 are stacked in the sheet tray 2. Next, when the rack plate 53 slides, the arm 60 of the push plate 59 engaged with the rack plate 53 rotates, causing the push plate 59 to retreat. As the push plate 59 retreats, the plurality of logic detection plates 31 that have been separated thereby come into contact with the logic surface of the logic plate 35. At this time, the logic detection plate 31 engaged with the sheet fixing plate 27 facing the upper sheet layer 24 of the required sheet 1 falls into the recess 40 of the logic plate 35 in the selected state as described above, and the sheet fixing plate 27 is It is rotated and displaced to the engagement position of the kick-up plate 39. This state is the fourth
This is the seat fixing plate 27 indicated by the two-dot chain line in the figure. During this period, the rotation of the triangular cam 14 continues, and when the stationary state of the sheet tray 2 in the sheet selection section 4 approaches the end, the rotating roller 23 of the arm 20 begins to enter the recess 16' of the cam surface 16 of the rotating table 17. , cam surface 1
The arm 20 rotates along the recess 16' of 6 and slides the rack plate 53 in the direction of arrow 2 in FIG.
This sliding causes the pinion cam 51 to rotate, and the cam surface 52 raises the kick-up plate 39, and the upper sheet layer 24 of the required sheet 1 engaged therewith.
The seat fixing plate 27 facing the is raised. As a result, sheet 1 located above required sheet 1
The whole thing is clamped and fixed with the press plate 28. This state is the seat fixing plate 27 shown by the dashed line in FIG. Also, by sliding the rack plate 53, the arm 6
0 rotates to move the push plate 59 forward and separate the logic detection plate 31 from the logic plate 35 so as not to create sliding resistance on the logic plate 35 when selecting the next sheet. Next, at this point, the rotating roller 23 of the arm 20 escapes from the recess 16' of the cam surface 16 provided on the rotating table 17, and at the same time, the driving arm 11
The stationary state in the sheet selection section 4 is completed, and the rotation toward the sheet display section 3 begins. Along with this, the sheet tray 2 supported by the slider 7 has the necessary sheet 1 and the lower sheet layer 25 located below it.
Store everything and start moving to the sheet display section 3.
When the triangular cam 14 further rotates and the drive arm 11 enters the stationary state at the dead center of the seat display section 3, the switch 64 operates to turn off the entire energization [plunger 43, motor 18], and the motor 18 is turned off. The rotation is stopped, the plunger 43 is returned, and the sheet selection operation is completed. As is clear from the configuration and operation of the sheet selection mechanism of the multi-item information input device as an embodiment described above, the operating device of the present invention is structurally simple, and the selection mechanism itself is small and does not take up space. can do. Furthermore, the number of plungers themselves can be reduced compared to conventional ones, and compact ones with small capacity can be used to operate light loads with short strokes.
In addition, the power supply capacity itself can be reduced, and the power-on time is also extremely short. Furthermore, it can be set in advance to a selection standby state, which has the effect of eliminating wasted operating time.
Note that the operating device of the present invention can select one output member from among many output members [sheet fixing plate 27] using a small number of logic members [logic board 35], and especially as the number of output members increases, Very advantageous. The present invention provides an operating device that has many advantages as described above.
