Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is applicable to VTRs, CD players, video disc players, DATs, etc.
The present invention relates to a jog dial-like switch for performing reverse slow motion, frame advance and volume up / down.

[0002]

2. Description of the Related Art In recent years, jog dial-like switches have been adopted in VTRs, CD players, video disc players, DATs and the like for forward and reverse slow motions, frame advance and volume up / down.

Such a jog dial switch is
For example, as shown in FIGS. 1 and 2, the printed circuit board 4 is provided with the rotary member 3 positioned in the concave portion 2 of the operation panel unit 1.
Is attached to the rotary shaft 6 of the rotary encoder 5 attached to the.

[0004] In the operation, for example, in the case of slow frame feeding of a video, the rotary member 3 is pinched and rotated right or left. On the other hand, when the frame feed is performed quickly, the tip of the finger is lightly applied to the recess 3a of the rotating member 3, and the rotating member 3a can be rotated at high speed by turning the finger in this state. In this way, the rotation direction and the rotation amount are detected by the signal from the rotary encoder 5, and a signal (not shown) for the control unit (not shown) to instruct the direction and the amount or speed of the frame advance of the video according to the detection result. Is output to the playback mechanism side.

As a principle of operation of such a rotary encoder 5, for example, in Japanese Patent Laid-Open No. 52-142411, as shown in FIGS.
It is disclosed that the above-mentioned instruction signal is obtained on the basis of the light interrupted by 1 and 12.

In the rotary encoder 5, a disk 10 having openings 11 and 12 that partially overlap each other in the angular direction is rotatably arranged with a shaft 15 as a fulcrum. Light-emitting diodes 25 and 26 and phototransistors 22 and 23 are arranged facing each other at positions corresponding to the openings 11 and 12. By rotating the disk 10,
A pair of square waves are obtained as collector outputs of the phototransistors 22 and 23 by interrupting light from the light emitting diodes 25 and 26, respectively.

The collector output of the transistor 22 is adapted to be applied to the clock input of each flip-flop 16, 17 via an amplifier 18, each flip-flop 16, 17 being at the falling edge of the collector output of the transistor 22. Triggered.

The collector output of the transistor 23 is applied to the D input of the flip-flop 17 via the amplifier 19.

Now, when the disk 10 rotates clockwise and the edge 14 of the opening 11 allows the light of the light emitting diode 25 to pass through, the collector output of the transistor 22 changes from the high level to the low level, and the flip-flop 16 changes its level. Triggered on the falling edge, producing a logic one on the Q output. This signal is used as an interrupt signal to the microprocessor, and when the microprocessor receives this interrupt, it applies a reset signal to the R input of the flip-flop to reset it.
As a result, a pulse signal corresponding to the number of times the opening 11 has passed, in other words, according to the rotation amount is obtained.

The rotation direction is determined by the Q-bar output of the flip-flop 17. That is, when the disk 10 rotates in one direction, a logic 1 is generated at the Q-bar output of the flip-flop 17, and when the disk 10 rotates in the other direction, a logic 0 is generated at the Q-bar output of the flip-flop 17. To do.
That is, since the data indicating the presence / absence of the clock generation is given to the D input of the flip-flop 17, it is possible to know which of the edges 14 and 13 of the opening 11 the clock has generated. .

[0011]

As described above, in the conventional jog dial switch described above, the rotary encoder 5 detects the rotation direction and the rotation amount by rotating the rotation member 3 shown in FIG. It is possible to obtain a signal for instructing the direction and amount or speed of the video frame advance.

However, in the jog dial switch described above, as shown in FIG. 2, since the rotating member 3 which is a movable part is required, the number of parts increases,
In addition, there is a limit to the thickness of the jog dial-shaped switch because of its structure, which is an obstacle to making the operation panel unit 1 thin.

Further, when the rotating member 3 is rotated at a high speed, as described above, the tip of the finger is lightly pressed into the recess 3a, and the finger is rotated in this state. Since the rotation locus is determined by the radius of the center of the rotating member 3 and the recess 3a, the circular motion of the finger is restricted, and the operability deteriorates.
By the way, as the rotational movement of the finger becomes faster, it becomes more difficult to move it in a perfect circle, and it becomes naturally distorted.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a jog dial-like switch which can reduce the thickness of the operation panel portion and improve the operability with a simple structure. To do.

[0015]

In order to achieve the above object, a jog dial switch of the present invention includes a contact or non-contact switch section having a plurality of detecting sections arranged on a surface thereof.
And a control means for outputting a predetermined output signal according to the on / off state and / or change of the switch section.

[0016]

In the jog-dial switch of the present invention, the rotation direction and the rotation amount are detected based on the ON / OFF state and / or change caused by contact or non-contact with a plurality of detecting portions arranged on the surface. Therefore, it is possible to eliminate the conventional rotating member.

Further, by forming the switch portion in the form of a film, for example, it is possible to dispose the switch portion not only on a flat surface but also on a curved surface.

Further, unlike the conventional rotary member, the operation locus is not restricted and the circular movement of the finger can be performed in an arbitrary shape, so that the operation can be performed easily.

[0019]

Embodiments of the present invention will be described below in detail with reference to the drawings. In the drawings described below, the same parts as those in FIGS. 1 to 4 are designated by the same reference numerals, and a duplicate description will be omitted.

FIG. 5 shows an embodiment of the jog dial-shaped switch of the present invention, in which a capacitance type touch type switch section 30 is provided on the operation surface of the operation panel section 1. The switch part 30 is provided with a plurality of chrysanthemum-shaped sensor parts 31. Each sensor part 3
1 is provided flush with the operation panel unit 1 so as not to be uneven.

When the switch unit 30 is operated, for example, as shown in FIG. 6, by tracing the surface of the sensor unit 31 with a finger, the rotation direction and the rotation amount are detected as described later. At this time, a guide groove or a guide protrusion may be provided on the surface of each sensor unit 31, or a protrusion or the like may be provided at the center of each sensor unit 31, as shown in FIGS.
In this case, blind touch is possible, and the sensor unit 31 can be easily traced.

The switch section 30 is not limited to the touch type as in this example, but may be a capacitance type non-touch type, or may be constituted by other detecting means such as a pressure sensor. .

By the way, when a switch unit such as a capacitance type non-touch type or a pressure sensor is adopted, it is not necessary to expose the electrode section on the surface of the operation panel section 1, so that the operation panel section 1 is not exposed. The operation surface can be made clear.

Such a switch portion 30 is formed by, for example, the hot stamping method shown in FIG. That is, in this method, the transfer film is thermocompression-bonded to the operation panel unit 1 which is a molded product by a transfer machine. The transfer film includes a base film 31e, an adhesive layer 31a which is a foil layer 31A, a sensor layer 31b, a coloring layer 31c, and a release layer 3.
1d is stacked. The entire transfer film is thermocompression-bonded to the operation panel unit 1 in a state where the adhesive layer 31a side is in contact with the operation surface side of the operation panel unit 1 and then the base film 31e is peeled off to form the foil layer 31A serving as the sensor unit 31. Are formed on the panel portion 1.

The colored layer 31c may be formed not only in one layer but also in a plurality of layers in order to obtain a predetermined color. Further, since the foil layer 31A has a thickness of about 0.2 to 1 mm, the unevenness can be extremely small even when it is thermocompression bonded onto the operation panel unit 1.

The material of the operation panel section 1 which is the transferred material is preferably a thermoplastic resin such as PS or AS.
Reference numeral 31f in the drawing denotes a lead wire, which is formed in a state of being connected to the sensor layer 31b in advance.

FIGS. 8 and 9 show another molding method by in-mold molding. The foil layer 31 is composed of an adhesive layer 31a, a sensor layer 31b, a coloring layer 31c and a surface layer 31g.
A is set in the mold and the above-mentioned P is applied from the adhesive layer 31a side.
By injecting a thermoplastic resin such as S or AS, the foil layer 31A
And the resin layer 30A are integrally molded.

Reference numeral 31f in the drawing indicates a lead wire,
Reference numeral 31h indicates a connector that is retrofitted to the lead wire 31f.

FIG. 10 shows another forming method by the vacuum method. For example, the foil layer 31A composed of the adhesive layer 31a, the sensor layer 31b, the coloring layer 31c, and the peeling layer 31d described above is previously formed by the vacuum method (a). As described in (b), the resin layer 30A made of the thermoplastic resin such as PS or AS is molded inside the heat-deformed foil layer 31A.

The foil layer 31A and the resin layer 30 are
It may be formed by a so-called laminating method in which A and A are separately manufactured and then combined by hot pressing or the like.

FIG. 11 is for controlling the controlled circuit section 44 which controls the reproduction of the video signal and the volume up / down based on the detection signal from the capacitance type touch type switch section 30. The configuration of the control system is simply shown. As shown in FIG.
When touching, the capacitance change detection unit 40 detects the change in capacitance. The waveform shaping unit 41 includes the capacitance change detection unit 40.
The detection result of the change in the capacitance of is converted into a digital signal.

The control section 43 controls the respective waveform shaping sections 41.
The operation of the controlled circuit section 44 such as the reproducing mechanism and the amplifying circuit is controlled based on the digital signal from.

Here, the sensor unit 31 is turned on / off by a finger.
The determination of the off state or the on / off change is performed as follows, for example. That is, for example, when the output pulse width from the waveform shaping section 41 is wide, it is determined that the rotation speed of the finger tracing each sensor section 31 is slow. On the other hand, when the pulse width from each waveform shaping section 41 is narrow, it is determined that the rotation speed of the finger tracing each sensor section 31 is high.

FIG. 12 shows another embodiment in which the arrangement of the sensor section 31 of the switch section 30 is changed. In the figure, the sensor unit 31
Although circular shapes are shown for A and 31B, they are not limited to this example and may be chrysanthemum-shaped as described above.

In this example, two pairs of the sensor section 31A and the sensor section 31B are provided, and the sensorless section 3 is provided between the sensor section 31A and the sensor section 31B.
1X is interposed and each is arranged on the circumference.
The change in the capacitance of each sensor unit 31A, 31B is detected by the capacitance change detection unit 40A, 40B, respectively.

Here, the number of each sensor section 31A and sensor section 31B is the same as the sensor section 31A and the sensor section 31B.
A plurality of sets (two sets in this example) are provided as one set of B and the sensorless portion 31X.

However, the interval between the sensor portions 31A and 31B which are adjacent to each other is as follows.
It is preferable to separate them so that they can touch 1A and the sensor unit 31B with their fingers straddling them. As a result, & output from the sensor unit 31A and the sensor unit 31B is obtained as described later, which makes it easy to determine the turning direction of the finger. However, each sensor part 3 arranged on the circumference
It is not preferable to make 1A and the sensor unit 31B dense enough to touch three or more fingers, because it becomes difficult to determine the turning direction of the finger. The sensorless portion 31X is necessary to create a state in which neither the sensor portion A nor the sensor portion B is touched.

Further, the above-mentioned guide groove and guide protrusion are
You may make it provide along the dotted line shown in the same figure.

If the above conditions can be satisfied, in an extreme case, as shown in FIG. 13, for example, only one set of the sensor section 31A and the sensor section 31B can be provided.

Here, assuming that the outputs when the sensor portions 31A and 31B are touched with fingers are A and B, for example, the change in the output when rotating clockwise is A → A &
B → B → 0 → A → A & B → B → 0 ... On the other hand, when turning counterclockwise, B → A & B → A → 0 → B → A &
B → A → 0.

The waveform shaping output of the waveform shaping section 41B is adapted to be applied to the clock inputs of the flip-flops 16 and 17 via the inverter 180, and the respective flip-flops 16 and 17 drop the pulse passing through the inverter 180. Triggered on the edge.

Now, when the finger rotates clockwise and the finger touches the sensor section 31B, the output of the inverter 180 changes from the high level to the low level, and the flip-flop 16 is triggered at the falling edge of the flip-flop 16 to output Q. Generates a logical one. This signal is used as an interrupt signal to the control unit, and the control unit receives the reset signal and outputs the reset signal to the flip-flop 16
To the R input of to reset it. As a result, a pulse signal corresponding to the number of times the sensor unit 31B is touched, that is, the amount of rotation is obtained.

The rotation direction is determined by the Q-bar output of the flip-flop 17. In other words, when the touched sensor unit changes from A to A & B and the clock generated when B is touched is A, 1 is 1, so the D input of the flip-flop 17 is 0. Therefore, with this clock, the data D appears on the Q bar, so that 1 is obtained as the rotation direction signal.

Therefore, when the finger rotates clockwise, a logic 1 is generated at the Q-bar output of the flip-flop 17, and when the finger rotates counterclockwise, the Q-value of the flip-flop 17 increases.
A logic 0 occurs on the bar output.

If the operator first touches B or A & B, the rotation signal may be erroneous at the time of the first clock generation. It may be arranged so that it does not operate at the first clock in the section.

FIG. 14 shows a case where the detection method shown in FIG. 12 is performed by software, and shows an example of raising / lowering the frequency and volume. In this example, two sets of sensor unit 31A, sensor unit 31B, and sensor unit 31C are arranged on the circumference. Further, the corresponding sensor unit 31A, sensor unit 31B, and sensor unit 31C of each set are connected to each other, and the respective outputs are taken into the sensor detection circuit 50. It is assumed that the sensor detection circuit 50 removes noise that causes malfunction in the detection output from each of the sensor units 31A, 31B, and 31C.

The detection result of the sensor detection circuit 50 is I / O.
It is taken into the CPU 51 via the port 52. CPU
51 is up, down, according to a predetermined program
Outputs count pulse signal.

FIG. 15 shows a combination table of ON / OFF of each sensor unit 31A, sensor unit 31B and sensor unit 31C. However, in the figure, the sensor section 31A, the sensor section 31B, and the sensor section 31C are indicated by A, B, and C, respectively.

In such a configuration, the CPU 51 has the configuration shown in FIG.
The on / off state of the finger and the on / off change are determined according to the flow of. That is, ON / OFF of each sensor unit 31A, sensor unit 31B, and sensor unit 31C is scanned, and N corresponding to this ON / OFF combination is determined from the table of FIG. 15 (step 1601). If N corresponds to any one of 1, 2, and 4 (step 1602), the time count value T is reset to 0 (step 1
603) Similarly, after performing the second scan, FIG.
N is determined based on the table (step 1604).

If N is 1, 2, or 4 (step 1605), N 2 at the time of the second scan
And the difference between N1 at the first scan and N2-N1
It is determined whether is 0 (step 1606).
If N2-N1 is not 0, the time count value T
Holds the value of (step 1607).

Next, it is judged whether or not the absolute value of N2-N1 is 3 (step 1608). If it is judged as 3, it is judged whether N2-N1 is smaller than 0 or not. (Step 1609). If it is determined that it is smaller than 0, an up pulse signal is output (step 16).
10).

When outputting the up pulse signal, for example, if T is 100 msec or more, the count pulse is output once, and if T is less than 100 msec, the count pulse is output twice (step 1611).

On the other hand, when it is determined in step 1608 that the absolute value of N2-N1 is not 3,
It is determined whether N2-N1 is 0 or more (step 1612). If it is determined that the value is 0 or more, the process proceeds to (step 1610). In addition, (Step 1
612) and (step 1609), it is determined that N2-N1 is not greater than 0, and N2-
If it is determined that N1 is not less than 0, a down pulse is output (step 1613). The output of the count pulse follows (step 1611).

In this way, the count pulse corresponding to the rotation direction (up / down) and the rotation speed can be obtained.
Further details will be described.

That is, it is detected in (step 1602) that any one of A, B and C is touched. Here, the state in which the finger touches two or three fingers is excluded. (Step 1605) is similar,
By (step 1606), the change from the previous scan is checked, and if there is a change, the time T required for it is held at (step 1607).

(Step 1608) becomes YES when N is 4 and 1, that is, when there is a movement between A and C. Next, by checking the magnitude relationship in (step 1609), it is possible to know which one is moved. For example, when N2 is smaller than N1, it is moved from C to A.
That is, the rotation direction is determined to be clockwise, and the up pulse is output. At this time, if T is smaller than a predetermined value, it is considered that the rotation speed is high, and more pulses are generated per unit time so as to change the frequency and volume steps quickly.

On the other hand, the result of (Step 1608) is NO when there is a change between AB and BC, but in this case, as can be seen in FIG. It is determined in step 1612). It should be noted that the number of sensor units, whether or not touching over a plurality of sensor units is used as a determination condition, the stage of the rotation speed, and the like may be appropriately set.
