Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data input device used in a video tape recorder for setting data such as timer reservation and time setting.

[Conventional technology]

Conventional data input devices for setting the time and timer reservation date and time used in video tape recorders are numeric keys and r-keys.
The numerical value is set by forwarding or backward forwarding the number using ``4-'', r-J, etc.

Also used is a VTR in which numerical values are input using a jog shuttle to control the tape playback speed.

[Problem to be Solved by the Invention] However, in such a conventional input device, when setting the recording start time to 6 o'clock using the "+" key and the "-" key, for example, it is necessary to input the r+J key six times. This forces the user to perform complicated operations. Also, when using numeric keys, the position where the numerical value is input and the position where the input numerical value is displayed are not adjacent, so the user must alternately move his/her line of sight between the key and the display position to confirm the key strength. In all cases, it was not possible to immediately input the numerical value.Also, in all cases, the correspondence between the key force and the display position was not clearly established, so the user had to You need to learn how to use it from the manual, and VT
This was a big burden when using R. On the other hand, when inputting using the jog shuttle, the user cannot understand how to input numerical values, so it is necessary to input numerical values based on the user's manual. Furthermore, since a jog shuttle is required to set the time, cue, etc., there is a drawback in that it places a heavy burden on the user.

In this way, with conventional video tape recorders, there is no clear correspondence between the input values and the display, and the user needs to learn how to use them from the user's manual in advance.
This has the disadvantage that it is a heavy burden when using a VTR.

The present invention has been made in view of such conventional problems, and its technical object is to improve the operability of the numerical input section and reduce the burden on the user.

[Means for Solving the Problems] As shown in FIG. 1, the present invention includes a position detection means, a display means for displaying a numerical input section and a data setting section, a numerical input section control means, and a data setting section control. and a display control means for outputting a display control signal, wherein the position detection means outputs the input position signal on the plane, and the numerical input section of the display means outputs the input position signal on the plane. , a numerical key section, a change key section for changing input numerical values, and a numerical display section for displaying input numerical values; the data setting section of the display means is for displaying data to be set; The control means determines the input numerical value based on the position signal on the plane displayed on the numerical input section and detected by the position detection means, and outputs the numerical value to the display control means as numerical display data, and controls the data setting. The control means is
The present invention is characterized in that setting data is selected and output to the display control means based on a match between the data setting section of the display means and the position signal input by the position detection means.

[Effect]

According to the present invention having such features, the display means displays a numeric key section, a change key section for changing input numerical values, a numerical display section for displaying input numerical values, and a data setting section. If the position detected by the position detection means is at the position of the numerical display section, the numerical input section control means obtains the input numerical value from the detected position and outputs the input numerical value as display data of the numerical input section. Further, if the detected position is at the position of the data setting section, the data at that position is assumed to have been set and is displayed on the data display section.
