Description

[Detailed description of the invention] The present invention uses a sheet cartridge consisting of a plurality of display sheets displaying data such as items to be input, and by arbitrarily replacing the display sheets on the display surface of the device, The present invention relates to a multi-item input device that inputs various data by changing the definition of input keys.

FIG. 1 is a perspective view showing the general appearance of an example of this type of multi-item input device. It is Toritsuji,
Reference numeral 3 denotes a device main body, which includes a hook portion 2; an input display portion 4 that constitutes an input keyboard with transparent electrodes formed in a matrix, and displays a plurality of items that can be input; and the sheet cartridge 1. A function key 6 for specifying a display sheet of a desired page is provided on the same surface as a page selection key 5 for positioning it below the input display section 4, and a page selection key 5 for specifying various functional operations. is provided with an entrance 7 for inserting and ejecting the sheet cartridge 1.

FIG. 2 is a side view showing a schematic configuration of a rotating drum section inside the multi-item input device. A claw portion 9 that engages with the hook portion 2 of the seat cartridge 1 is formed by cutting out a part of its outer periphery. Reference numeral 10 denotes an endless guide belt that is wrapped around a part of the rotating drum 8 and supported by a plurality of rollers so as to pass along a certain route.
Reference numeral 1 denotes a guide plate for inserting and ejecting the sheet cartridge 1. Reference numeral 12 denotes a guide plate for guiding a selected display sheet of the sheet cartridge 1 below the input display section 4 shown in FIG.
The tip of this guide plate 12 serves as a separator 13 for separating a selected display sheet from other display sheets.

Therefore, in the above-described configuration, when loading the sheet cartridge 1 into the apparatus main body 3, first insert the sheet cartridge 1 through the entrance/exit 7 of the apparatus main body 3, and then attach the hook part 2 at the tip of the sheet cartridge 1 to the rotating drum 3.
By engaging the pawl portion 9 and then pressing the function key 6 that instructs loading, the rotary drum 8 is rotated by a predetermined amount in the positive direction indicated by the solid arrow a, thereby rotating the sheet cartridge 1. It is wound between the outer periphery of the drum 8 and the guide belt 10. Each display sheet of the sheet cartridge 1 is made of a flexible material such as plastic film, and therefore the sheet cartridge 1 is wound around the rotating drum 8 by the above-described operation.

After loading the sheet cartridge 1 into the main body 3 of the apparatus in this manner, when a page is specified by pressing any page selection key 5, the edge of the display sheet of the selected page is placed above the separator 13. At this point, the rotating drum 8 rotates in the opposite direction indicated by the dotted arrow b, and the selected display sheet is separated from the other display sheets, pulled out along the guide plate 12, and positioned below the input display section 4. .

In this state, the operator finds the desired item from the display sheet displayed on the input display section 4,
An input operation is performed by pressing the input key using the transparent electrode at the display position. After that, when another page is selected, the rotating drum 8 rotates again in the direction of the solid line arrow.
The display sheet on the guide plate 12 is rolled up and another page is selectively rotated.

When ejecting the sheet cartridge 1 outside the device main body 3, press the function key 6 to instruct ejection.
When pressed, the rotary drum 8 rotates in the direction of the dotted arrow, and the sheet cartridge 1 advances along the guide plate 11. When the claw portion 9 comes off the hook portion 2, the sheet cartridge 1 is moved from the entrance 7. This is done by pulling out.

As explained above, the multi-item input device using the sheet cartridge 1 which is detachably attached to the rotating drum 8 is very effective in expanding the inputtable items. There is a problem in that the required length of the guide belt 10 changes depending on the presence or absence of the guide belt 10, the change in the outer diameter of the rotating drum 8 due to the winding of the sheet cartridge 1, etc.

Therefore, in the conventional multi-item input device, the above-mentioned problem is dealt with by configuring the rotating drum section as shown in FIGS. 3 and 4. That is, in FIGS. 3 and 4, 14 is a center drum located between the left and right rotating drums 8 (not shown here), and a guide belt 10 is wound around a part of the outer circumference of this center drum 14. ing. This guide belt 10 is supported by a plurality of rollers 15a to 15d, one of which is the roller 15.
a is pivotally supported at one end of the bracket 16. The other end of the bracket 16 is rotatably supported by a shaft 17 fixed to a frame (not shown), and a spring 1 is attached to the shaft 17.
8 is attached to urge the bracket 16 in a direction away from the center drum 14 as shown by the arrow.

This configuration can accommodate changes in the required length of the guide belt 10 by applying tension to the guide belt 10 via the roller 15a, but the bracket 16 and the spring 1
8 etc. is required, which has the disadvantage that the number of parts increases and the structure becomes complicated.

Furthermore, if tension is applied in the direction of the arrow shown in FIG. 3, when the lock by the motor (not shown) that rotates the center drum 14 is lost, the center drum 14 is moved to the guide belt 10 in the direction of the dotted arrow b in FIG. This also has the disadvantage that a turning force acts on the display sheet, which causes a misalignment in the positional relationship between the item display section of the display sheet and the input keyboard formed of transparent electrodes formed in a matrix.

The purpose of this invention is to solve these drawbacks, and for this purpose, a hook part provided at one end of a sheet cartridge consisting of a plurality of flexible display sheets displaying data such as items to be inputted is used as a device. Engage with the claws provided on the circumferential surface of the rotating drum in the main body to wind it into the rotating drum, position any display sheet separated according to the amount of rotation of the rotating drum at the input position, and press the input key. In a multi-item input device for inputting various data with different definitions, the rotating drum is provided with a large notch in the circumferential direction and the claw portion is provided so as to span the entire width of the rotating drum, and the hook is engaged with the claw portion. a hole in the center of one end of the sheet cartridge, and a guide belt made of an elastic material that presses the sheet cartridge against a part of the circumferential surface of the rotating drum. It is characterized by:

To explain the following with reference to the drawings, FIG. 5 is a perspective view showing a schematic configuration of a rotating drum section in an embodiment of the present invention, and FIG. 6 is a side view thereof.
indicates an endless guide belt, and this guide belt 19 is made of a stretchable material such as urethane so that it can stretch within a predetermined length range. It is wrapped around a part of the outer periphery of the rotating drum 8 and supported by a plurality of rollers 20a to 20d so as to pass along a certain route. Further, the rotary drum 8 is provided with a claw portion 9 which is largely cut out in the circumferential direction and spans the entire width of the rotary drum 8, and furthermore, the sheet cartridge 1
(See FIG. 1) is provided with a hole in the center of one end thereof to form a hook portion 2 into which the claw portion 9 engages. Note that the other parts of the apparatus main body 3 and the like are the same in configuration as shown in FIG. 1, so their explanation will be omitted.

Next, we will explain the operation of the above configuration.
When inserting the sheet cartridge 1 into the apparatus main body 3, the rotating drum 8 is stopped in the state shown in FIG. 6, and the claw portion 9 is waiting with a large gap between it and the guide belt 19. .

Therefore, when the sheet cartridge 1 is inserted from the entrance/exit 7, its tip advances toward the rotating drum 8 under the guidance of the guide plate 11 shown in FIG. 2, and when the sheet cartridge 1 is further inserted to the reference position, the hook portion 2 reaches the inside of the notch of the rotating drum 8.

After doing this, when the function key 6 for instructing loading is pressed down, the rotary drum 8 is rotated in the direction of the solid line arrow shown in FIG. 1 and engages with the hook portion 2. As the rotating drum 8 further rotates, the sheet cartridge 1 is wound up between the outer peripheral surface of the rotating drum 8 and the guide belt 19 and is sequentially wound around the rotating drum. The outer diameter of the rotating drum 8 increases, but at this time, the guide belt 19 stretches to follow the change in the outer diameter of the rotating drum 8 due to its own elasticity, and at the same time maintains an appropriate tension on the seat cartridge 1.
In addition, it acts to maintain an appropriate positional relationship between the claw portion 9 of the rotating drum 8 and the sheet cartridge 1. Then, when the display sheet of the sheet cartridge 1 is selected, or when the rotating drum 8 rotates in the opposite direction to eject the sheet cartridge 1 and its outer diameter becomes smaller, the change in the outer diameter is followed. The guide belt 19 then contracts.

As explained above, the present invention has a structure in which an elastic guide belt is wound around a part of the rotating drum, and the guide belt allows the sheet cartridge to be wound around the rotating drum. Since the belt length follows the change in the outer diameter of the belt, there is no need for conventional brackets, springs, etc. This has the effect of reducing the number of parts and simplifying the configuration.

In addition, in this invention, the guide belt has elasticity, and the seat cartridge can be wound around the rotating drum while allowing a certain amount of slack. Since it does not leave marks or cause the sheet cartridge to sag during winding, it also has the effect of preventing misalignment of the keys on the input display section of the device main body. It will be done.

Furthermore, the rotating drum is notched largely in the circumferential direction to provide the claw portion so as to span the entire width of the rotating drum, and the hook portion that the claw portion engages is provided with a hole in the center of one end of the sheet cartridge. Since it is formed by the above-mentioned method, it is also possible to obtain the effect that operations at the time of winding in and discharging can be carried out reliably and smoothly.
