Description

[Detailed Description of the Invention] <Technical Field> The present invention defines each key switch of a data input key switch group by a display that displays the names of various items of data to be input, and changes this definition. Therefore, the present invention relates to a data input device that can input various data.

<Prior Art> Conventionally, this type of input device has generally been of the bookmark type. This bookmark type has a plurality of bookmarks bound together in a so-called book shape, and each bookmark has a through hole corresponding to each keytop of the input key switches arranged in a matrix on the keyboard. There is. Furthermore, the names of various items of data to be input are displayed in each of the holes. When a suitable page of this booklet consisting of a plurality of sheets is opened, the key tops of the input key switches arranged on the keyboard protrude from the respective through holes of the page. Therefore, it is now possible to input data corresponding to the displayed characters by opening an appropriate page and operating the key tops protruding from the holes in which the desired data names are displayed.

As described above, since the conventional data input device is in a bookmark format, it is necessary to open a plurality of bookmarks one by one in order to select each page, and this is currently done by the operator himself. The reason why page selection has not been performed automatically in the past is that a very complicated mechanism and control are required to automatically perform the operation of opening a bookmark.

<Object of the Invention> In view of the above-mentioned drawbacks of the conventional art, the present invention has been proposed in order to facilitate the selection operation when selecting a page. An object of the present invention is to provide a data input device that can prevent a display from being damaged due to a key being pressed.

<Example> The present invention will be explained in detail below based on the drawings.

FIG. 1 is a schematic diagram of a data input device according to the present invention, FIG. 2 is an operational state diagram of the device, FIG. 3 is a diagram showing an example of a display body used in the device, and FIGS. 4 a and b are in accordance with the present invention. It is a figure which shows each Example.

In FIG. 1, reference numeral 1 indicates a display body made of a soft member that displays the names of various items of data to be input for multiple pages, and this display body is a spool whose rotation is controlled by a processing device (not shown). The spool 2 is wound around the spool 2, and as the spool 2 rotates, it moves toward a group of data input key switches, which will be described later. Reference numeral 3 indicates key switches arranged in a matrix on the keyboard 4, and the key switches 3 are located below the display 1 as shown in the figure, and the key tops 5 of the switches are slightly away from the back surface of the display 1. is held in 6 is a hinge etc. (not shown) on one side of the device body.
The transparent plate 6 is made of acrylic or the like and is rotatably mounted on the display 1, and the transparent plate 6 is held horizontally at a position corresponding to the keyboard 4 with the display 1 interposed therebetween. 7
1 shows a switch knob provided on a transparent plate 6 so as to be slidable in the axial direction, and this switch knob 7 is always energized by a coil spring 8 so that its tip part is separated from the surface of the display body 1. The switch knobs 7 are provided corresponding to the key tops 5 of the key switches arranged in a matrix on the keyboard 4.

According to the above configuration, when the spool 2 rotates according to a command from the processing device, the display 1 displays the key top 5 of the key switch as the spool 2 rotates.
and the tip of the switch knob 7. When a desired page appears and the display position of the page corresponds to the key top 5 position of the key switch on the keyboard 4, the rotation of the spool 2 is stopped.

Then, the display on the selected page is confirmed through the transparent plate 6, and when the switch knob 7 corresponding to the desired display is pressed against the coil spring 8, the switch knob becomes as shown in FIG. The part of the display body 1 facing the tip of 7 is recessed,
In conjunction with this, the key top 5 of the key switch is pressed, thereby inputting desired data.

Further, as shown in FIG. 3, a through hole 9 is pre-drilled in a portion of the display body 1 corresponding to each key top 5, so that even if the display body 1 is relatively hard, the through hole 9
The key top can be directly pressed with the tip of the switch knob 7 via the button.

However, in the data input device as described above, if the operating means is pressed down while the display is being moved, there is a risk that the display may be damaged. The present invention is further characterized in that a protective means for preventing this is provided, and will be explained in detail with reference to FIG. 4a.
1 is a display body made of a soft material, 3 is a key switch, 6 is a transparent plate, and 7 is a switch knob. 10 is a roller provided at the tip of the switch knob 7. Even if the operating means is pressed down while the display is moving, the display will not be damaged because the roller 10 rotates as the display moves. In other words, the roller 10 serves as a protection means for preventing the display from being damaged even if the operating means is pressed down while the display is moving.

FIG. 4b shows another embodiment, in which the same parts as in FIG. 4a are given the same numbers. 7 so that it does not touch the display 1 even if the switch knob 7 is pressed down. In other words, the stopper serves as a protection means to prevent the display from being damaged even if the operating means is pressed down while the display is moving.

<Effects of the Invention> As described above, the data input device of the present invention is provided with operating means for operating each key switch in a data input key switch group, and the operating means and each key switch are connected to each other. are arranged facing each other at a certain interval, so that the display body can slide during the certain interval, and the display body is damaged when the operating means is pressed down while the display body is moving. Since the protective means is provided to prevent the display from being damaged, even if the operating means is accidentally pressed while the display is being moved, the protective means can prevent the display from being damaged. Further, since the display body is not damaged by the protection means, there is no need to replace the display body, which is very economical.
