Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-item input device that is provided with a plurality of item sheets that define a large number of item keys, and that allows input of a large number of item names by changing the vertical position of the item sheet. More specifically, the present invention relates to a sorting sheet display mechanism that displays selected and positioned item sheets at the top.

In the multi-item input device, a large number of item keys are arranged in a matrix, and each item key is defined by guiding a desired item sheet directly under the item key.

Then, by operating a desired item key, coded information corresponding to the item key is applied to the data processing device, and the coded information is input from the item name table corresponding to the item sheet led directly under the item key. Read the corresponding data.

Therefore, not only can different data be read by operating different item keys, but also different data can be read by operating the same item key or by changing the item sheet. It is possible to input a large number of items determined by the product of the number of item keys and the number of item sheets.

In such a multi-item input device, it is necessary to be able to easily change the vertical position of the item sheet, so a plurality of item sheets are attached to a drum that can be rotated in forward and reverse directions.
Furthermore, a display device was installed to inform the operator which item sheet was sorted and positioned at the top.

The conventional display device is equipped with a light emitting element, etc. in or around the sheet sorting key, and is also equipped with a control section that selectively drives the light emitting element, etc. in accordance with the selected item sheet. ,
This not only complicates the mechanical and electrical configuration, but also increases the size and cost of the display device as a whole.

The present invention eliminates the above-mentioned drawbacks by omitting light emitting elements etc. by placing predetermined display marks at different positions on each item sheet.
Embodiments will be described in detail below with reference to the accompanying drawings showing examples.

Fig. 1 is a longitudinal sectional side view showing a multi-item input device equipped with the display mechanism of the present invention, Fig. 2 is an enlarged plan view of the main part, Fig. 3 is an enlarged plan view of the main part of the item sheet, and Fig. 4
The figure is an enlarged plan view of the main part of the index plate.

A guide plate 3 is provided below a transparent keyboard panel 1 in which a large number of item keys 2, 2... are arranged in a matrix, and the space between the keyboard panel 1 and the guide plate 3 is used as a guide space 4 for guiding item sheets. , a drum 6 on which a plurality of opaque item sheets 5, 5... are wound in a stack is provided in close proximity to the guide space 4, and rollers 7, 8, 9, 10, 11 are provided to surround the drum 6. Of the endless belt 12 made of an elastic material such as rubber stretched between the rollers 7, 8, 9, 10, 11, the portion located between the rollers 7, 11 closest to the guide space 4 is used to guide the drum 6. Pressed against the side surface separated from the space 4,
Furthermore, a sheet display mechanism 13, which is the main feature of the present invention, is provided in a portion of the guide space 4 adjacent to the drum 6.

By connecting the drum 6 to a motor (not shown), it can be rotated in forward and reverse directions, and
The rollers 7, 8, 9, 10, and 11 are connected to the motor so that the endless belt 12 runs at the same speed in the same direction as the circumferential surface of the drum 6 at the part where it comes into pressure contact with the drum 6.

Further, one side edges of a plurality of item sheets 5, 5, . . . are provided on the drum 6 directly or indirectly at equal intervals.

The keyboard panel 1 is made of a transparent substrate such as a glass plate, and item keys 2, 2, . . . , sheet selection keys 14, 14, .
are arranged.

The configuration of the sheet display mechanism 13, which is the gist of the present invention, is as follows.

A plurality of sheet selection keys 14, 14... are arranged in two rows at the end of the keyboard panel 1 closer to the drum, and a transparent index plate guide plate 15 is provided directly below the sheet selection keys 14, 14.... 1 and the index plate guide plate 15.
are inserted into the guide space 4, and page mark entry fields 17, 17, etc. are provided at predetermined positions near the drum of the item sheets 5, 5, which are further led to the guide space 4.

The index plate 16 is divided into a number of areas directly facing each of the sheet selection keys 14, 14, . It has

In addition, the corresponding page numbers 20, 2 among the page mark entry fields 17, 17, etc. of each item sheet 5, 5, etc.
A page mark 21 made of red color or the like is provided at a location corresponding to 0....

The operation of the multi-item input device configured as described above is as follows.

When selecting a desired item sheet 5, positioning the item sheet 5 at the top, stacking all the item sheets 5, 5, etc. and sending them out to the guide space 4, select the item sheet to be sorted. All you have to do is operate the sheet selection key 14 corresponding to the page number 5.
First, the drum 6 can be rotationally driven in the item sheet winding direction (counterclockwise direction in the figure) by rotating a motor (not shown) in the forward direction.

If the rotation of the drum 6 is continued even after all the item sheets 5, 5... have been wound up, the free edges of the item sheets 5, 5... can be sequentially released from the pressure by the endless belt 12.

Here, if a detection means (not shown) detects that the free edge of the item sheet 5 corresponding to the sheet sorting key 14 is released, the drum 6 is stopped, and then the drum 6 is reversed. All the item sheets 5, 5, . . . can be led to the guide space 4 with the item sheet 5 of

At this time, the page mark 21 made in the predetermined page mark entry field 17 of the selected item sheet 5
can be seen through the operated sheet selection key 14 and the transparent portion 18 directly facing the sheet selection key 14, and the page marks 21, 21, etc. of the other item sheets 5, 5, etc. cannot be seen through. Therefore, it is possible to immediately know at a glance that the desired item sheet 5 has been selected and positioned.

After selecting the desired item sheet 5 as described above, by operating the item key 2, coded information corresponding to the item key 2 encoded by a key circuit (not shown) is transferred to a data processing device (not shown). data corresponding to the coded information can be read from the item name table corresponding to the item sheet 5 located at the top.

In addition, when selecting other item sheets 5,
The above operation may be repeated again.

In the manner described above, it is possible to input many types of items determined by the product of the number of item keys and the number of item sheets.

Although the embodiment in which the item sheet is led to the lower level of the keyboard panel has been described above, the present invention is not limited to this embodiment at all; for example, the item sheet is led to the upper level of the keyboard panel. It is also possible to make other design changes as appropriate within the scope of not changing the gist of the present invention.

As described above, the present invention provides page marks for displaying page numbers at different positions on a plurality of item sheets, so it is possible to eliminate the need for light emitting elements, etc. for displaying page numbers. Not only can the structure be simplified by reducing mechanical parts and electrical parts, but
It has unique effects such as being compact as a whole and being inexpensive as a whole.
