Abstract

PURPOSE:To easily and accurately execute a program timer reservation by sticking a bar code seal in which a prescribed content is printed to a video cassette, reading bar code data in a data reader at the time of inserting the cassette and setting it to a timer recording stand-by mode after detection. CONSTITUTION:The bar code seal 2 is stuck to the upper surface of the video cassette 1, and bar codes 2a-2d showing the channel number, date, start time and an end time of a program to be recorded are printed in parallel on the seal 2. Here, four bar code sensors 11a-11d are provided in the front loading mechanic part of a VTR and signals from respective sensors 11a-11d are respectively waveform-shaped in waveform shaping circuits 12a-12d, are decoded in decoders 13a-13d, and are data-transferred to a timer control part 15. On the other hand, decoder outputs are supervised in a reading termination detection circuit 14, which generates timer recording stand-by signals St at the time of reading termination, transfers the signals St to the control part 15, whereby it automatically sets a system to the timer recording stand-by mode.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a program timer reservation device in, for example, a video tape recorder (hereinafter referred to as VTR).

(Prior Art) Conventionally, VTRs have been provided with a program timer reservation function so that timer recording can be performed when the user is absent.

To make this timer reservation, press the operation keys on the VTR or remote controller to monitor the screen display of the fluorescent display tube or picture tube, and then select the program you want to record. After sequentially inputting the channel number, day of the week, start time, end time, etc., insert the VTR set from the cassette cup entrance and load it, and finally press the timer recording standby setting key to complete the series of reservation operations.

The program timer reservation described above has a disadvantage that it is easy to make setting errors because the operating procedures are many and complicated. Furthermore, after completing the settings, the user may forget to insert the VTR cassette or forget to press the F3 setting button for timer recording, which may result in the inability to record the desired program.

In recent years, a barcode input method has been proposed to simplify the above reservation operation. This is the channel number,
Day of the week, start time, end time, etc. are entered by tracing a barcode printed sheet with a pencil-type barcode sensor.

However, even with this pencil-type barcode input method, the operation keys are simply replaced with barcode sensors, and there are problems such as making setting errors similar to key operations and forgetting to insert the cassette or set timer recording standby. Ta.

(Problems to be Solved by the Invention) As described above, in the conventional apparatus, the operation is complicated, resulting in input errors or forgetting to insert the cassette or set the timer recording mode.

Therefore, the present invention is intended to eliminate the above problems.
To provide a program timer reservation device which is easy to operate and does not cause setting errors or forgetting of settings.

[Structure of the Invention] (Means for Solving the Problems) The program timer reservation device of the present invention attaches a barcode sticker on which the channel number, day of the week, start time, end time, etc. of the program to be recorded to the video cassette. While it has a configuration in which it is pasted on one side, the VTR body side is equipped with a data reading means for reading barcode data when inserting a cassette.
The apparatus is configured to include a timer recording standby setting means for detecting the end of data reading and setting the timer recording standby mode.

(Function) In the present invention, simply by inserting the cassette with the barcode sticker affixed into the VTR main body, the -off timer reservation operation is automatically completed, so that operability can be improved and erroneous operations can be eliminated.

(Example) The present invention will be described below based on the example shown in the drawings.

FIG. 1 is a perspective view of a VTR cassette used in a program timer reservation device according to an embodiment of the present invention.

In this figure, reference numeral 1 is a VTR cassette, and a bar code sticker 2 is pasted on the top surface of the cassette 1. On the barcode sticker 2, barcodes 2a to 2d indicating the channel number, day of the week, start time, end time, etc. of the program to be recorded are printed in parallel.

The above barcode can be read by the barcode sensor attached to the VTR body when the cassette is inserted into the VTR body, and the cassette inserted is a 70mm cassette of the VTR.
Since the position is determined by the VT
By regulating only the pasting position of the barcode sticker 2 on the R cassette 1, it is possible to read the barcode satisfactorily even if the barcode is formed in a narrower width than the barcode used in a conventional pencil-type barcode sensor. It is.

Therefore, it is possible to write a lot of data necessary for timer recording.

FIG. 2 is a block diagram showing the configuration of a data reading section provided in the VTR main body, in which several (four in the figure) barcode sensors 11a to 11(j are provided in the front loading mechanism section of the VTR main body, The read signals from each sensor 11a to 11d are converted into waveform shaping circuits 128 to 12d, respectively.
After shaping the waveform, decoders 13a to 13d each decode the data and transfer the data to the timer control section 15. On the other hand, the reading completion detection circuit 14 monitors the outputs of the datars 13a to 13d, generates a timer recording standby signal St when reading is completed, and transfers the signal St to the timer control section 15. Automatically set to timer recording standby mode.

[Effects of the Invention] As described above, according to the present invention, it is possible to eliminate the troublesome key operations required in the related art, and it is possible to eliminate problems such as setting errors and forgetting settings.
