Abstract

PURPOSE:To facilitate the input of reservation information to a device by storing the reservation information of a timer in a reservation memory where information can be registered optionally and outputting the reservation information which is registered previously as the reservation information of the timer when an address bar code indicating an address of the reservation memory is swept. CONSTITUTION:This bar code reader is equipped with a bar code reader sensor 11, a decoder part 13 which converts the read bar code signal into a binary signal to replace the signal with binary information, a register 14 where the data is stored temporarily, and a data output part 15 which outputs the read data to equipment. Then the reservation memory 17 where the reservation information of the timer can be registered optionally is provided and when the bar code indicating the address of the reservation memory 17 is swept, the reservation information which is registered previously is outputted as the reservation information of the timer. Consequently, the reservation of the timer is enabled by the extremely easy operation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a barcode reading device that is effective for use in video tape recorders and the like that utilize barcodes.

Conventional technology In recent years, barcodes have been used for a variety of purposes due to their ease of operation, which allows a large amount of information to be entered at once with a small number of operations.Barcodes are also used for timer reservations in consumer video tape recorders. 5. Hereinafter, an example of the above-mentioned conventional barcode will be explained with reference to the drawings. FIG. 2 shows a block diagram of a barcode reading device used for conventional reservations, and 1 is a part of a sensor.

2 is an amplifier. 3 is a decoder section. 4 is a register. 6 is a data output section.

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

The sensor part 1 converts the strength of the reflected light into an electrical signal by sweeping the bar code from the light emitting element and the light receiving element which detects the light rays that are 4.1 times the angle of the bar code. The converted electrical signal is amplified by the amplifier 2 to a level necessary for binarization. The amplified signal is binarized by the decoder section 3 and replaced with binary information. The decoder section also determines whether the read 3-7 barcode is appropriate and determines the type of the read data. As information necessary for timer reservation, data is indicated by a bar code including a code indicating the data type of each of the reserved channel, reserved date or day of the week, start time, end time, or recording time length. The user sequentially sweeps a plurality of pieces of necessary data, and the decoder unit discriminates each read data and stores it in the register 4. After reading each pig, the user instructs the data output section 6 to output the data to the device, and the data output section 5 converts the data into the input format of the desired device and outputs the data. The output command may be performed using a button or by reading a bar code.

Problems to be Solved by the Invention However, although the above configuration can provide simple operation using barcodes, it is necessary to reserve a timer each time a user may use it frequently, for example, to reserve the recording of a movie. Sweep the barcode data of each reserved channel, reserved date or day of the week, start time, end time, or recording time length, or
There was a problem in that it was necessary to purchase a magazine in order to scan a series of barcodes written in a magazine or the like.

In view of the above-mentioned problems, the present invention allows a user to register in advance reservation information that he/she wishes to use that may be used frequently in a memory, and when he/she wishes to make a reservation, sweeps a barcode corresponding to the number in the memory. To provide a barcode reservation device that allows reservations to be made easily.

Means for Solving the Problems In order to solve the above problems, the barcode of the present invention comprises a barcode reading sensor, a decoder section that binarizes the read barcode signal and converts it into binary information, and a temporary A barcode reader equipped with a register for storing data and a data output section for outputting the read data to a device, and equipped with a reservation memory in which timer reservation information can be arbitrarily registered in advance. This device has a configuration that enables pre-registered reservation information to be output as timer reservation information when an address barcode having a code indicating an address is swept.

According to the above-described configuration, the present invention stores timer reservation information in advance in a reservation memory that can be registered arbitrarily, and when an address bar code having a code indicating the address of the reservation memory is swept, the timer reservation information is stored in advance. Since the reservation information can be output as timer reservation information, the input of the device reservation information can be completed.

EXAMPLE Hereinafter, a barcode according to an example of the present invention will be explained with reference to the drawings. FIG. 1 shows a block diagram of a barcode in an embodiment of the present invention.

In FIG. 1, 11 is a part of the sensor. 12 is an amplifier. 13 is a decoder section. 14 is a register. 15 is a data output section.

16 is a memory control section. 17 is a part of memory.

The operation of the barcode configured as described above will be explained below using FIG. 1.

The sensor part 1 converts the intensity of the reflected light into an electrical signal by sweeping a light-emitting element and a light-receiving element that detects the light reflected by the bar code. The converted electrical signal is amplified by an amplifier 2 to a level necessary for binarization. The amplified signal is binarized by the decoder section 3 and replaced with binary information. The decoder unit also determines whether the read barcode is appropriate or not, and determines the type of the read data. The information required to reserve a timer includes the reservation channel, reservation date or day of the week,
The data is indicated by a bar code containing a code indicating the data type, such as start time, end time, or recording time length. The user sequentially sweeps the necessary data, and the decoder section discriminates each read data and stores it in the register 4.

7. The user registers the reservation information temporarily stored in the register 4 in the desired reservation memory 17 by operating the memory control unit 16 in response to a reservation registration command by reading the reservation registration barcode. I can do it. The reservation memory has N addresses, and the user can register at any address. Reserved memory is constantly powered by a primary battery or secondary battery and retains its memory.

After reading each piece of data in this way, when the address barcode f with the code indicating the address of the reserved memory is swept, the memory control unit 16 detects that address and corresponds to the barcode indicating the address from the reserved memory 17. Copy the information of the address to the register 14. After confirming that the reservation details match the user's wishes, the data output unit 5 instructs the data output unit 5 to output the data to the device, and the data output unit 5 converts the data into the input format of the desired device. Output. The output command may be performed using a button or by reading a bar code.

Effects of the Invention According to the present invention, a barcode reading sensor, a decoder section that binarizes the read barcode signal and replaces it with binary information, and a register that temporarily stores the data are provided. It is equipped with a data output section for outputting the read data to the device, and has a reservation memory in which timer reservation information can be arbitrarily registered in advance. By outputting the reservation information as timer reservation information, it is possible to make timer reservations with an extremely simple operation.
