Abstract

PURPOSE:To simplify the mode conrol of a multi-function VTR including the JOG mode by applying the mode control by the absolute mode control assigned at each detection area ofa touch panel and applying the mode control by the operation control mode set corresponding to a secular change in the touch operating state of the touch panel. CONSTITUTION:When the touch operating state of the touch panel 10 transits from the operating state shown in figure A, that is, the state that no finger is touched into the touch operating state of a block shown in figures B (one finger touches), C and D, the change is detected as the pattern data change recognized by the block 40. Then a control data of the control operation mode displayed in the area touched in the touch panel 10 is outputted from the discrim ination block 70 and the control of the control operating mode is conducted with priority even when the VTR is so far in any operating state. For example, the tape positoin control of the VTR is applied by a control object position data given logarithmically in the area touched by the touch panel.

The touch panel type control data input device of this embodiment is applied to a video tape recorder (hereinafter simply referred to as VTR), and the panel surface of the touch panel 10, that is, the surface of the insulating coating 14, has a The control operation mode assigned to each area where the absolute position is divided into a plurality of areas is displayed.

The operating principle of the touch panel 10 is to utilize the capacitance of the human body, and when the user touches the insulating coating 14 with a finger, the detection electrode 12 and the ground electrode are formed.
13.The touch panel 10 can detect the capacitance change between each of the detection electrodes 13 and 13.
2 are sequentially scanned by the 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 contact operation state of the touch panel 10 as a pattern for each scan by the scanner 20. be done.

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.

The data comparator 60 then operates the recognition block 4.
The pattern data supplied from 0 and the second memory 5
The pattern data read from 0 is compared with the pattern data one scan before, and a change in the pattern data is detected. The comparison output data obtained by the data comparator 60 is sent to a judgment block 70 for outputting control data according to the comparison output data.
is supplied to.

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 3D, the state shown in FIGS. 3E and 3F in which the detection area of the touch panel 10 is touched in two directions, and the state shown in FIG. 3G There are situations where three or more detection areas are touched and operated at the same time. Note that 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

When the contact operation state of multiple blocks as shown in Figure Gζ is reached,
The VTR is set to still mode.

Furthermore, from the touch operation state of the one block or plural blocks, all fingers are moved almost simultaneously to the touch panel 1.
When vertically released from zero, the VTR continues its previous operation.

Furthermore, if you move your finger to the right or left without taking your finger off the touch panel 10 from the operation state of one block or multiple blocks, the VTR will respond to the finger movement regardless of the absolute division of the touch panel 10. , operates in a so-called JOG mode.
