Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a multi-item input device, and more particularly to a multi-item input device capable of inputting handwritten characters.

[Background of the invention]

A salesperson may create an order receipt at a customer's location, etc., and enter the data into a computer via a key-touch multi-item input device after returning to the office. At this time.

In order to check that there are no errors in the contents of the slips and the contents input into the device, complicated tasks such as putting check marks on the slips are performed.

FIG. 7 is a plan view of this type of input device, a Bentouch type multi-item input device. The coordinate position of Book 3 is detected by touching the electrostatic detection pen 5 to the square where the product name, etc. of Book 3 is written, and this coordinate position information is detected at the position of the silver paper 4 pasted on Book O. It is sent to the computer as item data along with the recognized page number and book number.

In addition, instead of the key-touch multi-item device, slip input may be performed via a handwritten character input device. FIG. 8 is a plan view of this type of handwritten character input device, in which when the operator writes handwritten characters in the squares of the character writing paper 1, the switch matrix board 2 writes the handwritten characters. Coordinate position information is generated in the writing layer of the character, this information is compared as binary information with a standard character pattern, the character is recognized, and the code of the character is sent to the computer. Such an input method forces the operator to enter a product code number or a long product name that is difficult to remember, which tends to slow the input speed and increase the time required to process the slip.

An example of a conventional input device is the device described in the CR-100 online handwritten kanji input terminal catalog (catalog number: J34103) of NEC Corporation.

[Purpose of the invention]

An object of the present invention is to provide a multi-item input device that combines the advantages of item selection and handwritten characters.

[Summary of the invention]

The present invention provides an item selection means for detecting the position coordinates of a switch on a switch matrix board when the switch is closed; A multi-item input device having means by which a handwritten character is recognized from a sequence of positions and means for identifying whether this closed switch is in an area on the board where an item is selected or in a handwritten character area. Features.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of the handwritten input type multi-item input device of this embodiment, in which the switch 7 is positioned in the horizontal direction at a position separating the item area 10 and the character area 11 on the item/character input paper 6. A movable switch and item area 10 are pre-printed with product names such as televisions, and an area where the operator manually enters checkmarks for necessary items and a character area 11 correspond to the necessary items. This is an area where numbers, such as quantities, are entered by hand by the operator.

In Figure 1, a punch hole 8 is punched in the upper side of the item/character input form B, so that the book number and page number can be detected, allowing handwritten input using check marks and characters. can be detected by the switch matrix board 2'.

FIG. 2 is a cross-sectional view of the part where the switch 7 is provided, and a conductive metal 12 is attached below the switch 7.
It comes into contact with two contacts 9 at the same time. For example, in FIG. 2, contacts 9 (E), contacts 9 (2), contacts (C) and (d), and (C) are connected by conductive metal 12 at the bottom of the switch 7, respectively.

FIG. 6 is a block diagram showing the control section of this embodiment, in which the clock CLK is counted by a counter 14 and its output is decoded by a decoder 17, resulting in 41 outputs.

...Only one line out of the two lines outputs high OV. Scanning is performed in this manner according to the increment of the counter 14, and when the line connected by the conductive gold M12 is scanned, this line becomes the Ov level, so the line α becomes the input to the encoder 20.

Only one line of J3-, . Depending on the bit position of the line that is at this Ov level) encoder 20
outputs a coordinate value X indicating the position to which the switch 7 has moved to the right when the upper left corner of the item/character input sheet 6 is set as the origin. In addition, the &-kfi of the contact 9 is input to the NOR gate 23, and its output and clock CLK are input to the AND gate 2.
4, the condition is satisfied only when the line connected to contact 9 is scanned, and the AND gate 24 is set to 1.
Output. This output operates a counter 15, and the output of the counter 15 is decoded by a decoder 18 to issue a signal for selecting one of the flip-flops 27-29. As a result, the position coordinate values X corresponding to each of the switches 7 are latched in the flip-flops 27 to 29. For example, in the example shown in FIG. 2, the values are when a hog is connected to the flip-flop 27, and the values 28 and d below are the values when chi and d, and 29 are the values when the beam and c are connected. The switch matrix port 2' is composed of a large number of switches 41, counts the clock CLK with a counter 16, decodes the result with a decoder 19, and moves downward (position (coordinate y direction). If there is a written input at this time, the switch 41 closes and the encoder 21
only the closed bit of the switch is O■ and the others are VO
O is input.

The line connected to the VOCI voltage via the resistor 13 receives the upper left corner output of the item/character input sheet 6, and the output of the encoder 22 becomes the position coordinate y. At this time, the output value of the encoder 21 and the 7-lip-flop 27~
Comparators 30 to 32 compare the output of encoder 21 with the output of 7 lip-flops 27 to 29, and if the output value of encoder 21 is larger than each output value of 7 lip-flops 27 to 29, 1. When it is small, it is 0.
The origin is the upper left corner of the item/character input form 6, and the position coordinate values x and y increase as you go to the right or down, so the input to the AND game) 25 and 26 is as shown in Figure 6. , the condition is satisfied only when the character area 11 is written with ■■.

The character hood generator 37 takes in and recognizes the position coordinates X and y when the output of the OR gate 35 is 1, and the item coordinate hood generator 68 operates when the output of the OR gate 55 is 0. It is.

The output 40 to the above-mentioned calculator is to switch the output of the character code generator 37 and item coordinate code generator 38 using the selector 36, and when the output of the OR gate 35 is 1, only the output of the character code generator 37 is output. , 0, only the output of the item coordinate code generator 38 is output.

FIG. 4 shows a cross-sectional view of the book number and page number detection section, which allows external light 42 to be taken in through a punch hole 8 made at a predetermined position of the item/character input paper 6, and which is located below the punch hole 8. A photodetector 39 detects the presence of a hole.

FIG. 5 is an output format diagram illustrating the format of data output to the host computer. In this embodiment, the sending data is a set of four, and the sending order is B, P,
The order is X and Y. When the host computer does not have (00) HKX in the received data, it recognizes it as a hood indicating item position coordinates, and when (oo)Hx:x exists, depending on whether the position is P or X, the host computer recognizes it as a character hood of ILs -06226. JLS-06220 character code is determined and processed.

As can be seen from the above explanation, if you use the handwritten multi-item input device shown in this embodiment, you can receive orders from outside the company and write check marks on the written order forms with a writing instrument such as a red pencil. By overwriting the number of entries, input can be made while checking, reducing input errors.

In addition, with conventional multi-item input devices, input is performed while looking at the form placed next to it, which requires tilting the head.Additionally, an indicator is required to show where on the form the form is being entered, which increases the risk of input errors. However, in this embodiment, the slip surface to be focused on and the input surface are the same, eliminating the need for fatigue and indicators as in the conventional method.

Furthermore, in comparison with handwritten character input devices, conventionally, it was necessary to manually input product food and product names one by one, which resulted in slow input speed, and due to fatigue due to the increased amount of writing, the characters could not be recognized properly. However, in this embodiment, long characters such as product codes are replaced with item instructions, reducing the amount of writing and fatigue compared to conventional handwritten character input devices.

In addition, if the hole diameter and hole pitch for detecting book numbers and page numbers are set in accordance with the JIS-85506 standard, there is no need to make special paper, and the settings can be easily made by the user. There are some advantages to doing so.

In addition, if all the switches 7 indicating area classification are moved to the left end, the entire area becomes character area 11, if all the switches 7 are moved to the left end, the entire area becomes item area 10, and if the switch 7 is increased, the area becomes even more. Needless to say, it can be subdivided.

It is obvious that the switch indicating the area division may be abolished, the area division may be fixed, and a switch for switching between the item/character input mode and the character input mode may be provided.

〔Effect of the invention〕

According to the present invention, since the advantages of item selection and handwritten characters are incorporated, it is possible to obtain a multi-item input device that has a fast input speed and can check whether the input is performed correctly manually.
