The present invention relates to a key matrix for use in equipment such as a video tape recorder and an on-time setting device for a selection function key of a remote controller.

The selection function keys used in the apparatus such as the conventional video tape recorder have been set on time uniformly. When using the apparatus, certain problems of the function keys due to the user's mistake are often caused.

For example, if the user presses the record button while watching a playback screen of the videotape or if it is selected by another person, the device detects the selection of the recording function key and simultaneously loads a video signal on the videotape.

Therefore, until one realized the fact and re-modified the selection of the function keys, unwanted video signals were removed from the video tape and inputted.

If the erased videotape was to be of great importance to the user, the severity of the problem would be even greater.

Thus, when a user experiences this, the user wants a device that operates only with the user's clear intention.

Accordingly, an object of the present invention is to provide an on-time setting device for a selection function key that can be operated only by a user's intention by setting different on-times for each selection function key in view of such circumstances.

The present invention for achieving this purpose is generated on the key matrix and the remote control, the on-time is set by the input signal of the predetermined first key and the input signal of the ten keys (0 to 9) at the time of setting the on-time, such as tracking An on-time setting device of a selection key in which the amount of data changing per second is set by a predetermined second key and a ten key when setting the on-time of a continuous key, which is used to set a predetermined input signal when setting the on-time of a plurality of function keys and a general key. Key matrix or remote control means consisting of an "ON TIME SET" key and a "continuous ON TIME SET" key that generates an input signal for setting the amount of data. Set the on-time and the amount of data changing per second by the controller, and control each function part by the set data. It is composed of timer microcomputer means that allow characters to be displayed on the screen and allow the user to work on-time in a more comfortable state.

Hereinafter, with reference to the accompanying drawings in detail as follows.

1 is a block diagram of the hardware for the configuration of the present invention, the key matrix (2) of the remote control (1) and the main body has a selection function key for performing a normal video tape recorder function, for example VOL ▲, VOL ▼, CH ▲ , CH, PWR, PLAY, REC, FF, REW, 0 to 9... A number of keys, such as and the like, and also the ON ON SET and CONTINUOUS ON TIME SET keys (not shown) are set in the present invention, and the power key (PWR) in the remote control 1 and the key matrix 2 is set. When is pressed, the power is supplied to the timer microcomputer 3, the on-screen display IC 4 shown in FIG. 1 and the respective functional parts not shown are enabled and the timer microcomputer 3 is turned on the digitron ( (Not shown) to allow him to display in text the function currently being performed.

The timer microcomputer 3 also controls the on-screen display IC 4 to display the corresponding characters on the television screen 5 at the time of program reservation and function execution.

This function is a general matter of the video cassette recorder and will be described in detail the operation process of the present invention.

According to the present invention, the setting process of the on-time setting device of the selective function key is divided into two types according to the function key. First, the general key (PLAY, REC, FF, RE…) is turned on by the first and second degrees. In describing the time setting, when the user presses the "ON TIME SET" key on the remote controller 1 or the key matrix 2, the timer microcomputer 3 detects this (step 101) and the on-screen display IC 4 receives this signal. And " KEY ON TIME " " KEY NAME? &Quot; on the television screen 5 by the data (step 102). At this time, the user can view the screen displayed on the television screen 5 and select a key to be set on time. ) Or on the key matrix 2, the selected key signal is detected by the timer microcomputer 3 (step 103), and the control signal and data by the signal are applied to the on-screen display IC 4, and on-screen Display IC 4 is applied By the ten-key "set key name" on the television screen (5) displays the time corresponding to the (not shown) (step 104).

Therefore, the user views the displayed contents (step 104) and selects the tenkey corresponding to the desired time zone from the remote controller 1 and the key matrix 2.

At the same time as the selection, the timer microcomputer 3 detects this (step 105). The content is applied to the on-screen display IC 4 and displayed on the television screen 5, and the RAM (shown in the microcomputer 4) is also displayed. Not saved). (Step 106).

In addition, when the user sets the on-key of another general key and selects the key on the remote controller 1 or the key matrix 2, the timer microcomputer 3 detects this (step 107) and repeats the process after step 104 above. When all the work is completed, the timer microcomputer 3 judges the presence or absence of the "ON TIME SET" key (step 108). When the "ON TIME SET" key is turned off, all the keys are returned to their normal state and the video recorder is inputted. Operation by the set time (step 109).

Next, a description will be given of FIG. 1 and FIG. 3 with respect to the on-time setting of successive keys (TRACKING ▲, ▼, CH ▲, ▼, VOL ▲, ▼, ..., not shown).

When the user presses the " continuous ON TIME SET " key on the remote controller 1 or the key matrix 2, the timer microcomputer 3 detects this (step 201). The on-screen display IC 4 receives a predetermined control signal and character. Data is applied, and the on-screen display IC 4 displays the corresponding text signal on the television screen 5.

That is, on the screen 5, "CONTINUOUS ON TIME SET" "KEY NAME?" (Step 202), the user views the display contents of this screen and selects one of the continuous keys set on time on the remote controller 1 and the key matrix 2, and at the same time the timer microcomputer 3 selects On detection (step 203), the on-screen display IC 4 displays the time zone set in the "key name set" and the ten key on the television screen 5 by the control signal and data (step 204).

Based on the contents shown on the screen, the user inputs the corresponding time by the tenkey of the remote controller 1 or the key matrix 2 for convenience, and this signal is detected by the timer micom 3 (step 205). 3) displays the time corresponding to the input signal through the on-screen display IC 4 and the television screen 5, and saves the input contents in the built-in RAM (not shown) (step 206).

After completing this operation, the timer microcomputer 3 detects the following (step 207). If the user selects to set the on-time of another consecutive key, the operation of step 204 is repeated. When all the work is completed and the "continuous ON TIME SET" key is turned off, it is detected (step 208) and all keys and television screens 5 operate in their normal function (step 209) and operate in the newly set time zone. .

As described above, the present invention solves certain problems caused by conventional uniformly selected selection function keys by setting the on-time setting of the selection function keys of the video tape recorder, which is a part of our daily life, according to the user's convenience. It can work.
