DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a touch panel type control data input device according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the electrical configuration of an embodiment of a touch panel type control data input device according to the present invention, and FIGS. 2A and 2B are diagrams showing the touch panel used in this embodiment. 10 is a partially cutaway front view and a partially cutaway bottom view schematically showing the structure of FIG.

In this embodiment, the touch panel 10 includes an insulating base material 11
Detection electrodes 12 and ground electrodes 13 are alternately and repeatedly arranged in parallel on one side, and an insulating coating 14 is laminated on the surface. Then, on the surface of the insulating coating 14,
The entire touch panel 10 is divided into a first area ARI, a second area ARI, and a second area ARI.
Thick protrusions, , L2 are formed to indicate boundaries dividing the area into area AR2 and third area AR3, and each of the first and third areas AR, , A&fe is further provided with three areas ARn.

ARI2, AR+3・AR31, AR32, ARss
Thin protrusion 4+ + ZI2 indicating the boundary of the division divided into
+41 +42 are formed.

The operating principle of the touch panel 10 is to utilize the capacitance of the human body, and the detection electrode 12 and the ground electrode 1 are generated when the user touches the insulating coating 14 with a finger.
Capacitance changes between 3 and 3 can be detected. In this touch panel 10, each of the detection electrodes 12 is sequentially scanned by a scanner 20.

The scanner 20 sequentially scans each detection electrode 13 of the touch panel 10 to detect the touch operation state of the touch panel 10 . The detection output data obtained by the scanner 20 is supplied to a first memory 30, and the detection output data for one scan is temporarily stored in the first memory 30.

The detection output data for one scan read out from the first memory 30 is supplied to a recognition block 40, and the recognition block 40 recognizes the touch operation state of the touch panel 10 as a pattern for each scan by the scanner 20. Ru.

The pattern data obtained in the recognition block 40 is
A second memory 40 and a data comparator 60 are supplied. The second memory 50 temporarily stores the pattern data supplied from the recognition block 40 for one scanning period of the scanner 10.

Then, the data comparator 6'0 compares the pattern data supplied from the recognition block 40 with the pattern data of the previous scan read from the second memory 50, and detects a change in the pattern data. . The comparison output data obtained by the data comparator 60 is processed by a judgment block 7 for outputting control data according to the comparison output data.
0.

The judgment block 70 reads out control data set in advance according to the touch operation state of the touch panel 10 from a data table (not shown) based on the comparison output data and outputs the control data.

Here, as the touch operation state of the touch panel 10 recognized by the recognition block 40, as schematically shown in FIG.
The state shown in Fig. A, and the state shown in Fig. 3B, in which one or a series of detection regions of each detection electrode 12 disposed on the touch panel 10 or a series of mutually adjacent detection electrodes are operated by touch,
The state shown in FIG. 3C or FIG. 3, the state shown in FIG. 3E and FIG. 3F where two detection areas of the touch panel 10 are touched simultaneously, and There is a state in which three or more detection areas are touched and operated at the same time. The determination of the detection area is as follows:
This may be done by utilizing the above-mentioned arrangement interval ε of the detection electrodes 12. Furthermore, as schematically shown in FIG. 4, this recognition block 40 detects a series of detection areas as shown in FIG. 4A based on the interval ε, and detects a series of detection areas as shown in FIG. 4B. After creating blocks, calculate the center and normalize the fourth
The normalized pattern shown in Figure C is recognized.

The touch panel type control data input device of this embodiment is a video tape recorder (hereinafter simply referred to as a VTR).

), and the first to third areas AR, AR2, AR3 of the touch panel 10 are assigned as control data input areas as follows.

The first and third areas AR, AR3 are for double speed in the reverse and forward directions.No matter what operating state the VTR is in, touching these areas will double the speed as shown in Table 1. The playback mode is set.

Table 1 The second area A& is an area used for JOG mode operation, and the user can move the second area A &
When the horse is touched, the following (2-t) and (2-2) are obtained.
Operation control is performed.

(2-1) When one finger is held fixed and the other finger is brought into contact with the other finger in the vertical direction and then released, the VTR moves in the direction of the moving finger, from 1 to It moves in steps for several frames, and when you stop moving your fingers, it goes into still mode.

17= (2-2) If you move two fingers vertically almost at the same time and release them from the touch panel 10, it will enter the still mode.
When two fingers are separated from the touch panel 10 with a time difference, the VTR operates in the direction of the finger that has left the finger at a speed corresponding to the distance between the fingers.

That is, in this embodiment, the touch operation state of the touch panel 10 is detected as a change in pattern data obtained by pattern recognition in the recognition block 40, and the touch operation state is detected as a change in pattern data obtained by pattern recognition of the touch operation state of the touch panel 10.
