Abstract

PURPOSE:To attain multi-function of operating control in a VTR by applying position control corresponding to the length of a touch panel with the contact operation to the touch panel and speed control, e.g., corresponding to secular change in the contact operation. CONSTITUTION:When the contact operating state of the touch panel 10 transits from the operating state shown in figure A, i.e., the state that no finger is touched, into the contact operating state of a block shown in figure B (one finger is contacted), C or D, the change is detected as a change in the pattern data recognized by a recognizing block 40, and the control data of the control operating mode represented on the region where the touch panel 10 is contacted is outputted from a discriminating block 70. Even when the VTR is in any operating condition before, the control operation of the control operating mode is conducted with priority. For example, when the center region of the touch panel 10 is contacted, the tape position control of the VTR is applied by using control object position data given logarithmically to the contacted region.

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 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 1
Detecting electrodes 12 and grounding electrodes 13 are alternately and repeatedly arranged in parallel on one side of 1, and an insulating film 14 is laminated on the surface. The loading is applied to a videotape recorder (hereinafter simply referred to as a VTR), and is applied to the panel surface of the touch panel 10, that is, the insulation coating 14.
The control operation mode assigned to each area is displayed on the surface of the area where the absolute position is divided into a plurality of areas.

The operating principle of the touch panel 10 is based on the capacitance of the human body, and the sensing 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. The touch panel 10 is arranged such that the detection electrodes 12 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 this 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 supplied to the second memo 1] 40 and the data comparator 60. The second memory 56 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 to the prisoner in FIG. 3B is one in which one or a series of detection areas of each of the detection electrodes 12 disposed on the touch panel 10 or a series of detection electrodes adjacent to each other is operated by touch.
, the state shown in Fig. 3C or Fig. 3, the state shown in Fig. 3E and Fig. 3F in which two detection areas of the touch panel 10 are touched simultaneously, and the state shown in Fig. 3G. As shown, there is a state in which three or more detection areas are touched and operated at the same time. Note that the determination of the detection area may be performed using 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 (B), the system recognizes the normalized pattern shown in Figure 4C, which is obtained by calculating the center of the block and normalizing it.

In this embodiment, the touch panel 10 has control targets whose entire length logarithmically corresponds to the tape length, with seven areas R and s at the center serving as data input areas for tape position control in a VTR. Assigned for entering location data. In addition, the touch panel 10
SF is the data input area for setting the playback speed in forward playback mode of the VTR.
It is assigned to input speed setting data of 11x speed + 33x speed + 10x speed and +5050x speed.

Furthermore, four areas A on the left side of the touch panel 10
RB serves as a data input area for setting the playback speed in the VTR's reverse playback mode, including -1x speed, -3x speed,
It is assigned to input speed setting data for -10x speed and 150x speed.

In this embodiment, the touch operation state of the touch panel 10 changes from the operation state shown in FIG.
When the contact operation state of one block shown in Figure B, Figure 3 C or Figure 3 is reached, the change is reflected in the recognition block 4.
The control data of the control operation mode that is detected as a change in the pattern data recognized by 0 and displayed on the touched area of the touch panel 10 is output from the discrimination block 70, and the control data of the control operation mode that is detected as a change in the pattern data recognized by Even in the operating state, the control operation in the control operation mode is performed preferentially.

For example, when the center area ARs of the touch panel 10 is touched, the tape position of the VTR is controlled based on control target position data logarithmically given to the touched area.

Also, touch the touch panel 10 with a plurality of fingers from the state where the fingers are released to touch the screen shown in FIG.
When the contact operation state of multiple blocks shown in Figure G is reached, V
TR 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 removed from 0, the VTR continues its previous operation.

Furthermore, if you move your finger to the right or left without removing it from the touch panel 10 from the above-mentioned one-block or multiple-block contact operation state, the touch panel 10 will respond to the finger movement regardless of the absolute classification of the touch panel 10. The VTR operates in a so-called JOG mode.

That is, in this embodiment, the control target position data corresponding to the length L of the central area All,s is obtained by the judgment block 70 by a touch operation on the central area ARs of the touch panel 10, and the control target position data corresponding to the length L of the central area All,s is obtained by the judgment block 70. It is possible to control the output.

Furthermore, it is possible to perform a JOG mode operation that corresponds to changes over time in the contact operation state of the touch panel 10.
