Abstract

PURPOSE:To quickly set to a target numerical value by dial operation concerning control signal generating device generating numerical up/down instructions for numerical tuning, such as time setting, channel setting, etc. CONSTITUTION:When the pulse output signal 4 of a pulse signal generating means 1 constituted to generate a pulse signal at each prescribed rotation angle of a dial 2 is generated not less than a previously-decided number in a prescribed time, a fixed value not less the previously decided number up instruction 12 is outputted. When the number of pulses generated in the prescribed time is not less than one and less than the previously decided number, a one-up instruction 13 is outputted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control signal generator for generating numerical up / down commands for setting numerical values such as time setting and channel setting for timer recording in a video tape recorder. Yes, it can be set quickly by dialing.

[0002]

2. Description of the Related Art Conventionally, as a control signal generator used for time setting and channel setting for timer recording in a video tape recorder, the one shown in FIG. 2 has been considered. In FIG. 2, reference numeral 21 denotes a remote control main body, on the surface of which a dial 22 is rotatably attached with a part of its outer periphery exposed. Then, by rotating this dial 2, dial 2
A command signal for increasing or decreasing the numerical value of the apparatus main body by one is generated for each predetermined rotation angle.

[0003]

Therefore, when there is a large difference between the set start value and the target value, such as when setting the minutes of the time, the target set value must be set unless the dial is rotated many times. There was a problem of not becoming.

[0004]

Therefore, when the control signal generator of the present invention detects a predetermined number or more of pulse signals in a predetermined constant period, the control signal generating device has a predetermined number or more. The constant value up command is transmitted to the apparatus main body.

[0005]

According to the above construction, when the dial is rotated quickly by one operation, a large amount of numerical value increase can be realized by one operation as compared with the case where the dial is rotated slowly, and the desired value can be increased at high speed. It is possible to adjust the numerical value to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a remote control device using the control signal generator of the present invention.

In the drawings, reference numeral 1 is a pulse signal generating means, which is configured to generate one pulse signal for each predetermined rotation angle (for example, 18 degrees) of the dial 2 having the above-mentioned configuration. The number of pulses indicates the rotation amount of the dial, and it is predetermined (20 pieces) per one rotation of the dial.
Pulse is obtained.

Reference numeral 3 is a pulse detecting means, which takes in the output signal 4 of the pulse signal generating means 1, and when the signal 6 indicating the timer operation of the timer 5 is not inputted at the arrival of the pulse, the timer In addition to outputting the count start command 7 to 5, the remote control code encoder 8 is instructed to send a 1-up command 9. On the contrary, when the signal 6 indicating that the timer 5 is operating is input, the 1-up command 9 to the remote control code encoder 8 is stopped.

The timer 5 starts an operation of counting a predetermined time (for example, 0.1 seconds) by the input of the timer start command 7, and when the time count is over, the timer operating signal 6 is turned off. It is configured.

The pulse number counting means 10 counts the output signal 4 of the pulse signal generating means 1 between the ON and OFF edge timings of the timer operating signal 6, and the pulse count value is a predetermined number. In the case of (for example, 5) or more, for example, 9 constant value increase commands 12 larger than the predetermined number 5 are output to the remote control code encoder 8 and the pulse count value is 1 or more and is set in advance. If the number is less than 5, the 1-up command 13 is output to the remote controller encoder 8. In the remote control code encoder 8, a 1-up command for the signal 9 or 13 and
The command for increasing the constant value of the signal 12 is converted into a remote control signal of a predetermined format, and this remote control signal is supplied to the transmission circuit 14.
The transmission circuit 14 is provided with a light emitting diode and a drive amplifier thereof, and the remote control signal converted into an infrared signal is transmitted from the transmission circuit 14 to the video tape recorder.

The remote control signal converted from the infrared signal to the electric signal by the receiving circuit 15 is supplied to the remote control code decoder 16. The remote control code decoder 16 commands the received remote control code to be incremented by 1,
It is decoded into corresponding code signals such as a constant value up command and sent to the display numerical value creating means 17.

In the display numerical value creating means 17, the numerical value of the display content buffer 18 is increased in accordance with the decoded instruction, and the numerical value of the display buffer 18 has a display control circuit and a superimpose circuit which are known techniques. The on-screen controller 19 is instructed to display data such as time. The on-screen controller 19
The display data is superimposed on a video signal, and the contents such as the instructed time and the like are displayed on the TV screen 20 as a video signal.

In the above-mentioned embodiment, the description about the rotating direction of the dial is omitted. However, when the dial is rotated in the opposite direction to the above-mentioned embodiment, the 1 down command or the
The constant value down command is configured to be generated through similar means.

The above embodiment is one in which the control signal generator is mounted on the remote controller. However, even when the control signal generator is mounted on the video main body, only the remote control code encoder and the decoder section are provided. Is omitted, and the same effect can be realized.

[0015]

As described above, according to the present invention, when the dial is quickly rotated by one operation, a large amount of numerical value increase can be realized by one operation as compared with the case where the dial is slowly rotated. Therefore, it is possible to quickly rotate the dial up to a value close to the target value, and slowly rotate the dial when the value is close to the target value, so that the values can be adjusted at high speed with a small number of dial rotation operations.
