Abstract

PURPOSE:To make a connection cable and a connector unnecessary and to improve operability by converting input information into a bar code signal and driving an optical shutter element in the timing of a time series obtained when the bar code is scanned. CONSTITUTION:A CPU3 converts information inputted to a terminal equipment 1 from the outside into bar code data, which is inputted to a driver circuit 5. A drive signal is outputted to the optical shutter element of an output panel 6 from the circuit 5. The optical shutter element repeats on and off corresponding to the bar code data on a time series. A bar code reader 7 is fixed on the optical shutter element of the panel 6. The timing of on and off of the optical shutter element is the same as that of a time series on and off signal inputted to the reader 7. Thus the same data made of the mark and space of the bar code is inputted to the reader 7, which can read out the contents of information on the bar code.

[Detailed Description of the Invention] 3. Revision of the Invention 1111I 1. [Industrial Application Field] This invention is to convert information from outside using 8tl of human power into digital data and 1. [2] Output method 2, especially when connecting with combinations and lights, eliminates the need for pull, and allows the operation of output and 7 devices. 1. Regarding the output method: 1. [Prior art] Converting information from the outside world into digital data, which is input from six types of sensors, measurement W, etc. Te: Yunbuta ni 11

In addition, the optical output method is one that transmits data through an optical fiber, and the electrical output method 1 or 9 is used. 7
In any of the Fj methods of the Fj location method, the connection data "1" and Rbim "J connector" for connecting the terminal device 1 and the computer 2 are required.

[The solution for light! -5) Problem 1: In the conventional digital data output method as described above, the terminal equipment
A connection cable such as an electric wire or optical fiber and its connector are required to connect the computer 2 and the computer 2.
The problem is that the connector must be inserted and removed each time the connection cable is attached or detached, making it difficult to operate, requiring special space for the connector, and in some cases, the connection cable gets in the way. Especially when it is not necessary to output data continuously all the time, or when it is desired to make the terminal device 1 such as a sensor or a measuring instrument portable, there is a problem that the connecting cable becomes a hindrance.

This invention was made in view of these problems, and eliminates the need for a connection cable and its connector between an output device and a computer, improves the operability of the device, and allows portable digital data to be transferred easily. It provides an output method.

[Means for solving problems]

The digital data output method of this invention converts information input from the outside into a time-series barcode signal in a predetermined format, and scans the barcode with a barcode reader. The optical shutter element is driven at the same timing as the signal on the series to output data of input information.

[Effect]

By converting the input information into a bar code and driving the optical shutter element in accordance with this bar code, it is possible to read the data of the bar code with the optical shutter element facing the 8-code league. Data can be output to a connected computer. Further, since the barcode reader is separated from the output device mounted on the optical shutter element, the operability of the output device is improved, making it suitable for portable use.

〔Example〕

FIG. 1 is a block diagram for explaining the overall configuration of the present invention. In FIG. 0, reference numeral 1 denotes terminal equipment such as various sensors, measuring instruments, key switches, etc., into which information from the outside is input. Reference numeral 3 denotes a CPU as a conversion means for converting input information outputted from the terminal device 1 into time-series barcode data according to a predetermined format, and 8-code format information is written in advance in the memory 4. 5 is a driver circuit (driving means) for driving an optical shutter element such as an LCD or PLZT in accordance with the barcode data; 6;
The output panel has the above-mentioned optical shutter element, and a reflector is attached to its bottom surface.

7 is a barcode reader connected to the computer 2 which is to output the barcoded digital data.

In the output device having the above configuration, information from the outside world taken into the terminal device I is input to the CPU 3, where it is converted into a digital signal and converted into barcode data based on the format information written in the memory 4. converted. The memory 4 has a ROM and a RAM, and the /H code format tN information is stored in the ROM. Further, the barcode data may be temporarily stored in the RAM, or data before being converted to barcode data may be stored therein.

The barcode data converted by the CPU 3 is read directly or as needed from the memory 4 and sent to the driver circuit 5.
The driver circuit 5 outputs a drive signal to the optical shutter element of the output panel 6. Then, the optical shutter element is 0N in response to the barcode data on the time series.
The computer 2
data can be transmitted to.

Next, the principle by which the barcode reader 7 reads the data output from the output panel 6 will be explained based on FIG. 2. The barcode reader 7 has recently been frequently used as a data input means for computers, and chronological data is inputted by scanning the barcode shown in FIG. 2(a) in its length direction. 8-A code is an alternating array of marks (black lines) and spaces (blanks), and the thickness and order of the marks represent specific information. 7, the data of the 8-code is input to the barcode reader 7. At this time, the barcode itself is a string of information along its length, but when the operator runs the code reader 7 to read the contents of the barcode, the barcode reader 7 Data that is a column of information on the time axis 1- is input.

Therefore, in the present invention, the barcode reader 7 is installed on the output panel 6.
The optical shutter element r- is fixed facing the optical shutter element r-, and the optical shutter element r is turned ON and OFF in chronological order. That is, since the barcode reader 7 itself has no way to detect linear movement due to scanning, the barcode reader 7 is fixed and the optical shutter element disposed in front of it is turned off. The ON-OFF timing of this optical shutter element is the same timing as the time-series ON-OFF signal input to the barcode reader 7 when the operator runs the barcode reader 7 (see Fig. 2). b) Reference)
As a result, the same data consisting of marks and spaces of the barcode is input to the barcode reader 7 (see FIG. 2(C)), and the information content of the barcode can be read.

] - The bar coat reader 7 is provided with a light emitting element and a light receiving element as a pair, and light from the light emitting element is input to the light receiving element according to the ON-OFF status of the shutter element of the cover panel 6. be done. Figure 3(a).

(b) shows the light emitting element, light receiving element and 1. and each L
It is a figure which shows the output cover panel 6 which comprised the 8-code reader 7 using ED (light emitting diode) 7a and FD (photodiode) 7b, and the LCD shutter using LCD (liquid crystal element) 6a as a shutter element. When the LCD shutter is blocked, that is, when the LCD 6a is ON, the light emitted from the LED 7a in the barcode reader 7 is transmitted to the PD 7b.
(see # in FIG. 3(b)), and at this time the barcode reader 7 determines that it is a mark. When the LCD shutter is in a transmitting state, that is, when the LCD 6a is OFF, the light emitted from the LED 7a passes through the LCDGa and is reflected by the reflection plate 6b on the bottom surface of the LED 7a, as shown in FIG.
The signal passes through D6a and is input to PD7b. At this time,
Barcode reader 7 is great! : #'IQ. As shown, the light from the LED 7a is input to the PD 7b according to the ON-OFF state of the LCD 6a, and the 8-code reader 7 is able to distinguish between the marks and spaces of the barcode and read the information within it. Can be done. In this case, if the output panel 6 has a segment configuration, the LCD 6a serving as the shutter element may be a one-segment sheet f'' having an appropriate area, and may be driven statically.

The principle of reading the data output from the output panel 6 using the barcode reader 7 has been explained above, but there is no need for a connection cable between the output panel 6 and the computer 2 that outputs the data, which improves operability. It becomes something that looks like this. That is, the troublesome operation of inserting and removing the connector when attaching and detaching the connection cable is eliminated, and additional space for the connector is also eliminated. Also, tt1
Coupled with the use of a Furano display panel as the cover panel 6, the device becomes smaller.

FIG. 4 is a blow diagram showing an embodiment of the present invention applied to a sales data aggregation device for all salesmen based on the above-mentioned principle. This embodiment is an electronic desk-L calculator (hereinafter referred to as 1tL) It is composed of: That is, 3.4 is a CPU and memory built into the calculator, and 6 is an output panel provided as a part of the calculator, forming a touch switch (membrane switch) 8 to be described later. Reference numeral 9 represents a display section of the calculator, and reference numeral 10 represents a memory provided in the calculator separately from the memory 4, in which calendars and the like are stored. 11 is a keyboard equipped with a numeric keypad and function keys.

The 51st ffl is a perspective view showing the external appearance of the calculator described in -1-, and the display glI9 is provided with a display element such as an LCD (not shown), so that the output contents of the LCD 6a can be displayed. Further, FIG. 6 shows the structure of the touch switch 8 mentioned above. This touch switch 8 is LCD6 af
Transparent electrodes 8c and 8d were formed on the L side of the LCD shutter used, and were laid on the surfaces of two sheet-like polyester films 8a and 8b with transparent properties, with spacers 8e and 8f interposed between them. They are arranged substantially parallel to each other and facing each other.

In the system configured as described above, the sales amount, product code number, customer number, etc., for example, are entered using the keyboard 11, and when the user returns home in the evening, the total for the day is entered into the company computer 2 using the bar code 7. In this case, since no bFa cable is required between the calculator and the computer 2, operability is improved. Moreover, since there is no need for mounting space for a connector for cable connection, and flat display elements are used for the display element and shutter element 6a, it is possible to make the device as large as a card calculator. In this embodiment, since a touch switch 8 is formed on the hm of the LCD 6a, the barcode reader 7 is pressed against this to output a start signal to the CPU 3, and data output from the output panel 6 can be automatically started. It is a rotation. At this time, since at least one hand of the barcode reader 7 is restrained during operation, this automatic start further improves operability.

Although not specifically shown in the drawings, it is possible to display the content of the output data or related data on the display element of the display unit 9, which will be even more useful. It is possible to display the current output (how many bytes) and how many bytes have been output (how many bytes are being output), and the meaning of the barcode being output can also be displayed as a code.

In this way, information related to the output data can be displayed together with the output data, making it easy for the user to use and allowing for clear operations. Note that the LCD 6a of the output spring Lr6 may also be used as the - section of the display element of the display section 9, and it is also possible to apply it to a watch equipped with an LCD display section instead of a calculator.

This embodiment is applied to a device that measures physiological changes due to interlocking, and in the figure, 12 is a clock timer that measures time, 13 is a blood pressure sensor that measures blood pressure, and 14 measures, for example, the pulse of the upper arm. 15 is a heart rate counter that measures the heartbeat rate; 16 is an acceleration sensor that measures the intensity of exercise; these sensors and counters are provided as necessary.

In order to measure physiological changes caused by exercise, for example, when riding a test bicycle for a predetermined period of time, physiological data such as blood pressure and pulse rate are input to the CPU 3 and stored in the memory 4.
be taken in. This data is retrieved from the memory 4 as needed and output from the output panel 6 to the computer 2 via the barcode reader 7. At that time, data can be transferred simply by placing the barcode reader 7 in front of the shutter element of the output panel 6, and there is no need for any connection cables to the computer 2, making it easy to operate and allowing free Ns to be used outdoors. It is also possible to perform That is, when a connecting cable is required as in the past, the connecting cable becomes a nuisance, the type of exercise is limited to indoor activities such as cycling, and the connecting cable extends from the computer 2, making it difficult for the subject to exercise. The psychological aspect of this problem was #1, and it was not possible to make the robot work freely both indoors and outdoors. In the present invention, as described above, there is no need to place the computer 2 and the barcode reader 7 near the subject, so accurate physiological data can be collected, and the location where the output panel 6 equipped with the shutter element is attached to the subject. If this is taken into consideration, it is also possible to transfer data without interrupting the M shift.

The embodiments related to the output device to which this invention is applied have been described above, but this invention can be widely applied to portable terminal devices that collect and output various data, and can also be applied to cases where programs are developed using barcodes, etc. It can be applied to barcode generators to bring great benefits.
