Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an input device that performs input by a predetermined operation for specifying a desired input item from a plurality of input items, and a method for quickly changing the input item displayed on the input section that performs the predetermined operation. The invention relates to an input device.

FIG. 1 shows a schematic diagram of a conventional example of a multi-item input device, where 1 is an input section for inputting information, and 3 is an input section on which the names of input items divided into predetermined sizes are displayed. 1 shows a film moving in the direction of the arrow in FIG. The film 3 is moved page by page by a film moving means (not shown) built into the input device 5, using the width A of the input section 1 as a feeding unit (page). Furthermore, each input item is designated with an address in the storage section of the control section (not shown) built into the input device 1, which stores the corresponding input signal indicating that an input has been made. ing.

As for the action, the film 3 located in the input section 1
When a user performs a predetermined item designation operation such as pen-touching or pushing a desired item from among the input items displayed on the screen, the control section reads the following information from the storage section.
Reads and outputs the input signal stored at the address corresponding to the specified item.

If the desired input field is on another page,
After the film 3 is moved by the film moving means and the necessary page is set in the input section 1, the item designation operation described above is performed.

However, in conventional input devices, the film is moved page by page (distance A), so when changing pages, if the film movement speed is V, It takes at least A/V time, and if you want to change the page at the end of one film to the page at the end of the other film, for example,
If the total number of pages of the film is n, it will take at least A/V x (n-1) time, resulting in a problem that it takes time to change pages, and input efficiency cannot be improved. .

One way to easily solve the above problem is to increase the moving speed of the film, but on the other hand, the faster the moving speed is, the more difficult it is to configure the position control means to stop the film at the desired page. There is a problem that there is a limit due to the complexity, and it also causes cost increase.

The present invention has been made in view of the above, and an object of the present invention is to provide an input device that performs input by a predetermined action of specifying a desired input item from a plurality of input items, and to provide an input device that is displayed on an input section that performs the predetermined action.

Next, the operation of this embodiment will be explained.

When a desired item is selected from among the input items displayed on the films 15-1 to 15-5 located on the guide plates 9-1 to 9-5 in the input section 11, a predetermined item designation operation such as pen-touching or pushing is performed. A control section (not shown) built in the input device 7 reads out the input signal stored at the address corresponding to the designated item from the storage section and outputs it.

If the desired input item is not available, select film 15.
After moving the films 15-1 to 15-5 to find the desired input item, the above-mentioned item designation operation is performed.The movement of the films 15-1 to 15-5 at that time will now be explained. First, film 15-1~1
5-5 is moved in the direction in which the films 15-1 to 15-5 are wound around the first film scanning shafts 13-1 to 13-5. When the pulse motor 39 is driven to rotate the bevel gear synchronous rotating shaft 41 in the direction of the solid line arrow in FIG.
3-5 and 17-1 to 17-5, the drive is transmitted to the first film scanning shafts 13-1 to 13-5 via the first drive transmission shafts 21-1 to 21-5. The film scanning shafts 13-1 to 13-5 rotate in the direction of winding the films 15-1 to 15-5. On the other hand, the fourth bevel gear 27 is configured not to rotate in the direction of the solid arrow described above by the drive of the pulse motor 39, but to freely rotate in that direction. The third bevel gear 33 and the second film scanning shaft 25 freely rotate. Therefore, the first film scanning axes 13-1 to 13-5 scan the films 15-1 to 15-1.
When the film 5-5 is rotated in the winding direction, the rotational force is transmitted to the second film scanning shaft 25 via the films 15-1 to 15-5. -1 to 15-5
The films 15-1 to 15-5 are moved in a state where a predetermined tension is maintained, and even when the movement is completed, the films 15-1 to 15-5 are loosened on the guide plates 9-1 to 9-5. Never.

Next, the films 15-1 to 15-5 are moved to the second film scanning axis 2.
5 will be explained. When the pulse motor 39 is driven to rotate the bevel gear synchronous rotation shaft 41 in the direction of the dashed arrow in FIG. and is transmitted to the second film scanning shaft 25, so that the second film scanning shaft 25 transmits the film 15-1 to
Rotate in the direction of wrapping 15-5. On the other hand, the second
The bevel gears 17-1 to 17-5 do not rotate in the direction of the broken line arrow mentioned above when driven by the pulse motor 39, but are configured to freely rotate in that direction. In this case, the first bevel gears 23-1 to 23-5 and the first film scanning shafts 13-1 to 13-5 freely rotate.
Therefore, when the second film scanning shaft 25 rotates in the direction in which the films 15-1 to 15-5 are wound, the rotational force is applied to the films 15-1 to 15-5.
The first film scanning axis 13-1 to 13-
5, the first film scanning axis 1
3-1 to 13-5 are films 15-1 to 15-5
The films 15-1 to 15-5 are rotated in the sending direction, and the films 15-1 to 15-5 are moved while maintaining a predetermined tension.

In this way, in the input device of the present invention, the second
Since the film scanning shaft 25 is provided, all the films can be moved by the same amount at the same time with a simple structure.

In addition, in this example, films 15-1 to 1
5-5 in the direction in which the films 15-1 to 15-5 are wound around the first film scanning shafts 13-1 to 13-5, a bevel gear is used to move the films 15-1 to 15-5 to the first film scanning shaft Films 13-1 to 13-5 were controlled to rotate, but film 15-1
~15-5 with a strong restoring force, or the first film scanning axis 13-1~1
3-5 is provided with, for example, a torsional spring that acts in the direction in which the scanning shafts 13-1 to 13-5 always wind the films 15-1 to 15-5, so that the first film scanning shafts 13-1 to 13 -5 is rotatable, and the second film scanning shaft 25 is driven by a pulse motor 39.
If the rotation can be controlled in both directions by driving the
There is no need to control the rotation of the first film scanning shafts 13-1 to 13-5, and the second film scanning shaft 2
5 rotates in the film feeding direction, the first film scanning axis is rotated by the restoring force of the film itself in the former case, and by the restoring force of the torsional spring in the latter case. Therefore, the film is moved in the direction in which it is wound around the first film scanning shaft.

Next, when comparing the changing time of the input items with the conventional device assuming that the moving speed of the film is the same (velocity V), it is found that the conventional device has the changing time of the entire input items displayed in the input section. In this embodiment, the films 15-1 to 15-5 on the guide plates 9-1 to 9-5 move synchronously with respect to V, so A'/V is obtained, but from the relationship A≫A', This embodiment takes a much shorter time, and in addition, in a conventional device, when changing the page at the end of one film to the page at the end of the other film, it takes at least A/V x (n-1). As mentioned above, in the case of performing substantially the same operations in this embodiment, the input items on each guide plate 9-1 to 9-5 only need to be changed (n-1) times. The time required for this is A'/V x (n-1), which is much shorter in this embodiment than in the above-mentioned relationship, and the time required for input operations that involve changing input items can be shortened. You can increase input efficiency.

Furthermore, a film of the same length W as the film 3 used in the conventional device was attached to each guide plate 9-1 to 9-5.
By moving the top, the number of display changes per one input item displayed on the input section is W/A' times in the conventional device, whereas it is W/A' times in this embodiment. , from the above-mentioned relationship A>>A', W/A<W/A', so the total number of input items in the input device can be increased.

The movement distance of the films 15-1 to 15-5 is controlled by moving the films 15-1 to 15-1 by the width A'.
Pulse motor 39 required to move 5-5
Assuming that the number of pulses to be supplied to is P, it goes without saying that the number of pulses obtained by multiplying the number of pulses P by an integral multiple may be supplied to the pulse motor 39 according to the moving distance. Further, in this embodiment, the pulse motor 39 rotates the films 15-1 to 15-5.
Although the movement of the motor is controlled by a motor other than a pulse motor, a bevel gear synchronous rotating shaft 41 may also be used.
For example, a handle or the like may be provided to move the films 15-1 to 15-5 manually.

Further, the rotational drive of the film scanning shafts 13-1 to 13-5 is not limited to the one using bevel gears as in this embodiment, but may be, for example, a normal gear, a chain system, a timing belt system, etc. It goes without saying that you can do it.

Therefore, according to this embodiment, the display section includes a guide plate, a film on which input items are displayed to be moved on the guide plate, and a first film scanning axis around which the film is wound from one end of the film. A plurality of films are arranged to constitute an input section of the input device, and a second film scanning shaft on which the respective films are wound together from the other end is provided on the input device, and a second film scanning shaft is provided on the input device; Since one of the film scanning axes is made to rotate as the main rotation and the other as the auxiliary rotation,
The moving distance of the film required to change the input items displayed on the input section can be extremely shortened, and the time required to change the input items can be shortened.

Since the present invention is within the scope of the claims, the input items displayed on the input section of the input device can be quickly changed.

Note that this invention can be implemented in other embodiments with appropriate changes.
