Abstract

PURPOSE:To enable a bar code reader itself to confirm read contents read by decoding bar code information stored in a memory into data which can be displayed and displaying them on a display device. CONSTITUTION:The bar code information which is converted by a bar code decoder 4 is stored in the memory 5 and the stored data is converted by a display decoder driver 7 into data which can be displayed to drive a display device 8. Consequently, the read bar code information is displayed at the point of time and a user confirms the display and outputs it to equipment such as a video tape recorder when the information is desired contents. Thus, the display decoder driver 7 which converts the memory contents for the display and drives the display device and the display device 8 are provided to enable the bar code reader itself to confirm whether or not the read information is normal.

Description

[Detailed description of the invention] Industrial applications The present invention utilizes barcodes to start the timer.

The present invention relates to a barcode reading device that can input information such as end time and reserved channel into a device.This device is effective when used, for example, when a barcode is used to schedule recording of a television broadcast program.

BACKGROUND OF THE INVENTION Due to the ease of operation of conventional barcode reading devices, the range of use of barcode reading devices is expanding to include consumer devices such as video tape recorders.

Hereinafter, an example of the above-mentioned conventional barcode reading device will be described with reference to the drawings.

FIG. 2 shows a block diagram of a conventional barcode reading device.

10 is a sensor, 11 is an amplifier, and 12 is a digitizer that has a certain threshold value and converts an analog signal into a digital (binary) signal. 13 is a barcode decoder, 1
4 is a memory that stores the decoded barcode information, and 15 is a remote control device that converts the information in the memory 14 into a signal (
This is a remote control signal generator for transmitting signals using a remote control (hereinafter abbreviated as remote control).

The operation of the conventional barcode reading device configured as described above will be described below.

First, the sensor 10 consists of a light emitting part and a light receiving part, and the light beam emitted from the light emitting part is reflected by the part where the bar code is printed and input to the light receiving part. In this case, the intensity of the input light changes due to the difference in reflectance. The light receiving section converts changes in the light into changes in electrical signals. The converted electrical signals are amplified by amplifiers 1, 6, 1-, and the analog signals amplified here are binarized into high and low levels by a digitizer 12 having a certain threshold. The signal output here is encoded based on the length of the time axis.

This signal is converted into a binary number by a decoder 13.

The converted barcode information is stored in memory 14. When it is desired to output barcode information to a device such as a video tape recorder, the information in the memory 14 is converted by a remote control signal generator 15Vc into a remote control signal that can be received by the device and transmitted.

Problems to be Solved by the Invention However, with the above configuration, there is a problem in that the read barcode information is output to the device and there is no way to check it other than displaying it on the display device of the device. In other words, even if different data were read by mistake, it could not be confirmed at the time of reading. This is because the barcode reading device itself does not have a display function.

In view of the above-mentioned problems, the present invention provides a barcode reading device which is equipped with a display device and can immediately display barcode information once stored in a reading memory.

Means for Solving the Problems In order to solve the above problems, the barcode reading device of the present invention includes a sensor that reads the barcode and converts it into an electrical signal, an amplifier that amplifies the electrical signal, and an amplifier that converts the amplified signal. A digitizer that converts the data into a digital signal, a decoder for the barcode signal, a memory that stores the decoded data, a remote control signal generator that converts the data in the memory into a remote control signal, and a remote control signal generator that decodes the contents of the memory. The device is equipped with a display device that displays images.

Effect: With the above-described configuration, the present invention decodes the barcode information stored in the memory into displayable data and displays it on the display, so that the content read by the barcode reading device itself can be confirmed. .

Embodiments Hereinafter, barcode reading devices according to embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a block diagram of a barcode reading device according to an embodiment of the present invention. In FIG. 1, 1 is a sensor. 2 is an amplifier.

3 is a memory having a certain threshold value and storing analog signal and digital information. 6 is a remote control signal generator for converting the information in the memory into a signal and transmitting it by a remote control. 7 is a display decoder driver that converts the contents of the memory into displayable data and drives the display device.

8 is a display.

The operation of the barcode reading device of this embodiment configured as described above will be described below.

The sensor 1 consists of a light emitting part and a light receiving part, and the light beam emitted from the light emitting part is reflected by the part on which the bar code is printed and is input to the light receiving part. In this case, the intensity of the input light changes due to the difference in reflectance. The light receiving section converts changes in the light into changes in electrical signals. The converted electrical signal is sent to amplifier 2
is amplified.

The analog signal amplified here is binarized into high level and low level by a digitizer 3 having a certain threshold value. The signal output here is encoded based on the length of the time axis. This signal is converted to 2 by barcode decoder 4.
Convert to base number. The converted barcode information is stored in the memory 5.

The stored data is converted into a displayable data by a display decoder driver 7 and drives a display 8. As a result, the read barcode information is displayed at that point. The user can check the display and, if the content is as desired, output it to a device such as a video tape recorder. When it is desired to output barcode information to a device such as a video tape recorder, the information in the memory is converted by the remote control signal generator 6 into a remote control signal that can be received by one device and transmitted.

As described above, according to this embodiment, by providing the display decoder driver 7 and the display 8 that convert the contents of the memory into a displayable one and drive the display, the barcode reading device itself can determine whether the read information is good or not. It becomes possible to confirm.

Effects of the Invention As described above, according to the present invention, by providing a display decoder driver and a display device that convert the contents of the memory into a displayable one and drive the display device, the barcode reading device itself can read and read information. It becomes possible to confirm the quality of the barcode, and it becomes possible to provide an extremely easy-to-use barcode reading device.
