Abstract

PROBLEM TO BE SOLVED: To change instantly a zooming ratio by operating a switch at the position of rotating ends of a rotor, and by detecting that the rotor has reached the position of rotating ends. SOLUTION: When a rotor 6 rotates, two slides 19, 20 slide individually on a current collector 10 and a resistor 11, and the rotating direction of a motor and rotating speed are controlled according to output value coming from a lead part 4b. With this, the zooming ratio of a zoom-in direction is changed. When the rotor 6 reaches the end position of one end, a compressor 6b of the rotor 6 compresses a sound arresting sheet 17 of a push switch 8 of the other end. Through the sound arresting sheet 17, a tact spring 16 is compressed to give a reverse rotation to the tact spring 16, and the push switch 8 is switched. The zooming ratio changes instantly on the basis of the signals of the push switch 8, which comes from the lead part 4b. As a result, an excellent easy-to-use feature is improved for operators.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary operation type electric component for changing a resistance value or the like by rotating a rotating body, and more particularly, to a rotating part having a self-return function for automatically returning the rotating body to a neutral position. Related to operation type electric components.

[0002]

2. Description of the Related Art A rotary operation type electric component having a self-return function of this type is used, for example, as a zoom-in / out operation means of a video camera, and a conventional example thereof is disclosed in Japanese Utility Model Laid-Open No. 6-26130. Things are known.

[0003] The rotary operation type electric component described in the above publication includes a rotating body having a slider, a receiving member for rotatably supporting the rotating body, and a return spring for automatically returning the rotating body to a neutral position. , And is generally constituted by a resistance board or the like fixed to a receiving member so as to face the rotating body, and an operating lever pressed by an operator's finger or the like is integrated with the rotating body.

In the rotary operation type electric component configured as described above, when the operator presses the operation lever to one of the end portions, the rotating body is moved from the neutral position against the elastic force of the return spring. By rotating in any one direction and the slider sliding on the resistance pattern formed on the resistance substrate, the resistance value output from the resistance substrate changes. Therefore, for example, by detecting the change in the resistance value and controlling the rotation direction and the rotation speed of the motor, the zoom-in or zoom-out operation can be performed according to the pressing direction of the operation lever. When the operator removes the pressing force on the operation lever, the rotating body automatically returns to the neutral position by the elastic force of the return spring, and the operation lever also returns to the initial state in conjunction with the rotating body.

[0005]

As described above, in the rotary operation type electric component having the self-return function, when the pressing force on the operation lever is removed, the rotating body automatically returns to the neutral position by the elastic force of the return spring. As a result, the rotating body is always held in the neutral position when not in use,
The rotating bodies can be rotated in opposite directions with respect to the neutral position.

However, when this kind of rotary operation type electric component is used as a zoom-in / out operation means of a video camera as in the above-described prior art, a resistance value which varies with a rotation angle of a rotary body is used based on the resistance value. Since the motor controls the motor to change the zoom ratio during zoom-in or zoom-out operation, for example, if you want to maximize the zoom ratio, the motor pushes the operation lever before maximizing the zoom ratio. When the pressure is removed, the rotating body automatically returns to the neutral position, and the driving of the motor stops while the zoom ratio is maximized. For this reason, the operator must continue to press the operation lever for a predetermined time until the zoom ratio becomes the maximum, and the operator may feel that the time is long, which improves usability. There was room for improvement.

[0007]

SUMMARY OF THE INVENTION The present invention is directed to a rotary operation type electric component having a self-return function, in addition to an output signal such as a resistance value which changes according to a rotation angle of a rotary body, a rotary terminal of the rotary body. A switch operated in position shall be provided. According to the rotary operation type electric component having such a switch, since the switch is operated at the rotation end position of the rotating body, when the rotating body is used as a zoom-in / out operation means of the video camera, the rotation body is at the rotation end position. The reaching is detected by the switch, and the zoom ratio can be instantaneously changed based on the detection signal, so that the convenience for the operator can be improved.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a rotary operation type electric component according to the present invention, a rotating body having a slider, a receiving member for rotatably supporting the rotating body, and an elasticity for automatically returning the rotating body to a neutral position. A rotary operation type electric component comprising a member and a substrate on which a sliding pattern is formed, wherein the slider slides on the sliding pattern with rotation of the rotating body, wherein at least one of the rotating bodies A switch is provided which is operated in the rotary end position of.

With this configuration, the switch is operated at the rotation end position of the rotating body. Therefore, when the switch is used as a zoom-in / out operation means of the video camera, the switch indicates that the rotation body has reached the rotation end position. Detect
The zoom ratio can be instantaneously changed based on this detection signal, and the convenience for the operator can be improved.

The switch may be operated at at least one rotation end position of the rotating body. However, if a pair of switches respectively operated at both rotation end positions of the rotating body are provided, a video camera is provided. When used as zoom-in / out operation means, the zoom ratio can be instantaneously maximized or minimized based on the detection signals of both switches.

The switch may be such that a slider contacts and separates as a movable contact with respect to a fixed contact formed on the substrate. A push switch is provided for pressing the movable contact of the push switch on the rotating body, and the push switch is disposed so as to be substantially orthogonal to a rotating surface on which the pusher rotates. In addition, the push switch can function as a stopper that regulates the rotation end position of the rotating body.

When the pusher is projected from the rotating body in the radial direction and the push switch is arranged on the side of the rotating body, the rotating body including the pusher and the push switch overlap in the height direction. Therefore, the thickness of the rotary operation type electric component can be reduced.

The push switch may be a single product. However, when the substrate is a flexible substrate and a fixed contact of the push switch is provided at an extended portion of the flexible substrate, the flexible switch can be slid onto one flexible substrate. The moving pattern and the fixed contact of the push switch can be formed, so that the number of parts can be reduced and the structure can be simplified.

In the push switch, the movable contact may simply contact or separate from the fixed contact. However, the push switch with a click using a dome-shaped tact spring which generates a click feeling when the movable contact is inverted. In this case, when the muffler sheet is laminated on the tact spring, the operator can know that the rotating body has reached the rotation end position by a click feeling generated when the tact spring is inverted, and press the rotating body. Since the child presses the movable contact of the push switch via the muffling sheet, the sound of collision when the push switch is operated can be reduced by the muffling sheet, especially when a metal leaf spring is used as the tact spring. It is valid.

In the case where the switch is a push switch with a click using a dome-shaped tact spring, a stopper for preventing the rotating body from over-rotating after the tact spring has been inverted is provided on a receiving member. The strength of the stopper that regulates the rotation end position of the body is increased, so that the tact spring can be prevented from being deformed or set due to excessive rotation of the rotating body.

Further, if a fitting portion is provided at the center of the top surface of the rotating body and the rotating body is rotated by an operation lever which engages with the fitting portion, the fitting portion is engaged. If the shape of the part is common, even if the design of the operation lever changes, the rotary operation type electric component can be shared, and the versatility of the rotary operation type electric component is enhanced.

The rotary operation type electric component 1 thus configured is mounted on a video camera which is an external device, and is used as a zoom-in / out operation means. In this case, as shown in FIG. 11, an operation lever 21 operated by an operator is attached to the rotating body 6 of the rotary operation type electric component 1, and the rotating body 6 is rotated via the operating lever 21. In the following description, the operation lever 21 is omitted. The operation lever 21 has a shaft portion 21a fitted in the fitting hole 6c and an engagement protrusion 21b locked in the engagement groove 6e. Part 2
By rotating the rotation member 1c, the rotating body 6 and the slider receiver 5 rotate integrally with the operation lever 21.

First, in a non-operating state in which no rotating operation force is applied to the rotating body 6, both arm portions 7 a and 7 b of the torsion coil spring 7 are connected to the spring receiving projections 3 formed on the receiving member 3.
c are locked to both ends 3e and 3f, respectively (see FIG. 6), and the rotating body 6 and the slider receiver 5 are held at the neutral position in FIG. 1 by the resilient force from these arms 7a and 7b. I have. In this case, the tip (contact point) of one of the sliders 19 is in sliding contact with the center of the current collector 10, and the tip (contact point) of the other slider 20 is in contact with the resistor 11 on the silver pattern 11c at the center. Because of the contact (see FIG. 8), for example, when +5 V is applied to both ends of the resistor 11 for use, as shown in FIG.
+2.5 V is output from the lead portion 4b of the flexible substrate 4.

When the rotating body 6 rotates clockwise in FIG. 1 from the neutral position, the sliders 19 and 20 slide on the current collector 10 and the resistor 11, respectively, and output from the lead 4b. Since the value increases from +2.5 V to +5 V, the zoom ratio in the zoom-in direction is changed by controlling the rotation direction and rotation speed of a motor (not shown) according to the output value. When the rotating body 6 rotates clockwise by about 45 degrees and reaches one end position, the rotating body 6
Pusher 6b presses the muffling sheet 17 of one of the push switches 8, and the tact spring 16 is pressed via the muffling sheet 17, so that the tact spring 16 is inverted and the push switch 8 is turned from off to on. Switch. Therefore, the push switch 8 output from the lead portion 4b
, The zoom rate can be instantaneously maximized based on the ON signal. When the push switch 8 is turned on, as shown in FIG.
Abuts against the stopper projection 3d of the receiving member 3 and further rotation of the rotating body 6 is prevented, so that no excessive pressing force is applied to the tact spring 16 from the presser 6b, and the tact spring 16
Is reliably prevented from being deformed. Note that the rotating body 6
Is rotated clockwise, the spring holding portion 6 of the rotating body 6 is rotated.
One end 61 of j presses one arm 7b of the torsion coil spring 7 against the resilient force of the torsion coil spring 7, and the other arm 7b of the torsion coil spring 7 receives the spring. It is separated from one end 3e of the projection 3c. At this time, the other arm 7a of the torsion coil spring 7 remains locked to the other end 3f of the spring receiving projection 3c (see FIGS. 6 and 7). The repulsive force in the clockwise direction will be stored, and if the above-mentioned rotating operation force on the rotating body 6 is removed,
The rotating body 6 and the slider receiver 5 automatically return to the neutral position shown in FIG.

Conversely, when the rotating body 6 rotates in the counterclockwise direction in FIG. 1 from the neutral position, the output value from the lead portion 4b decreases from + 2.5V to 0V. The zoom ratio is changed. When the rotating body 6 rotates counterclockwise by about 45 degrees and reaches the other end position, the pressing member 6b of the rotating body 6 presses the muffler sheet (not shown) of the other push switch 9, and this push switch 9 Since the switch 9 is switched from off to on, the zoom ratio can be instantaneously minimized based on the on signal. In this case, the other engaging projection 6h is connected to the receiving member 3
And the rotation body 6 is prevented from rotating further, so that the tact spring (not shown) built in the push switch 9 is reliably prevented from being deformed. In addition,
When the rotating body 6 rotates in the counterclockwise direction in this manner, the other arm 7a of the torsion coil spring 7 is pressed by the other end 6k of the spring holding portion 6j, and from the other end 3f of the spring receiving projection 3c. Break away. At this time, the one arm portion 7b of the torsion coil spring 7 is locked to the one end 3e of the spring receiving projection 3c, so that the torsion coil spring 7 accumulates the elastic force in the clockwise direction. When the above-mentioned rotating operation force on the rotating body 6 is removed, the rotating body 6 and the slider receiver 5 automatically return to the neutral position shown in FIG.

As shown in FIG. 10, the push switches 8 and 9 are turned on in a region where the output voltage does not change.
That is, the slider 20 has the silver patterns 11a and 11 at both ends.
It is after reaching the resistor 11 on b. By setting in this way, even if the characteristics are shifted to either side due to variations in parts dimensions or assembly, etc., after the output voltage (resistance value) has finished changing, the push switches 8 and 9 are both set. Can be reliably turned on.

[0032]

The present invention is embodied in the form described above and has the following effects.

A rotating body having a slider, a receiving member for rotatably supporting the rotating body, an elastic member for automatically returning the rotating body to a neutral position, and a substrate on which a sliding pattern is formed. In a rotary operation type electric component in which the slider slides on the sliding pattern with the rotation of the rotating body, a switch operated at at least one rotation end position of the rotating body is provided. Since the switch is operated at the rotating end position of the body, when the rotating body has reached the rotating end position, the switch detects that the rotating body has reached the rotating end position when used as a zoom-in / out operation means of the video camera. The rate can be changed instantaneously, and the convenience for the operator can be improved.

When switches are provided at both ends of the rotating body, the zoom in / out of the video camera can be reduced.
When used as an out operation means, the zoom ratio can be instantaneously maximized or minimized based on the detection signals of both switches.

In addition, a push switch is used as a switch in which the movable contact comes into contact with and separates from the fixed contact. A pusher for pushing the movable contact of the push switch is provided on the rotating body, and the pusher rotates. When the push switch is disposed so as to be substantially orthogonal to the surface, the push switch can function as a stopper that regulates the rotation end position of the rotating body.

Further, when the pressing element is protruded from the rotating body in the radial direction and the push switch is arranged on the side of the rotating body,
Since the rotating body including the pressing element and the push switch are arranged so as to overlap in the height direction, it is possible to reduce the thickness of the rotary operation type electric component.

Further, when the substrate is a flexible substrate, and a fixed contact of a push switch is provided on an extended portion of the flexible substrate, a sliding pattern and a fixed contact of the push switch can be formed on one flexible substrate. In addition, the number of parts can be reduced and the structure can be simplified.

Further, when the receiving member is fixed to the supporting plate via the flexible substrate, and the supporting plate is provided with a standing piece to which the extending portion of the flexible substrate is fixed, the receiving member and the push switch are mounted on the common supporting plate. It can be fixed, and the assembling work and the structure can be simplified.

In the case where a dome-shaped tact spring that generates a click feeling at the time of reversal is used as the movable contact of the push switch, if a muffling sheet is laminated on the tact spring, an operator is generated when the tact spring is reversed. It is possible to know that the rotating body has reached the rotation end position by a click feeling, and because the pressing member of the rotating body presses the movable contact of the push switch via the muffling sheet, the collision sound during the operation of the push switch. Can be reduced by the noise reduction sheet.

In the case of a push switch with a click using a dome-shaped tact spring, if a stopper is provided on a receiving member for preventing over-rotation of the rotator after the tact spring is inverted, rotation of the rotator can be achieved. The strength of the stopper that regulates the end position is increased, and deformation of the tact spring due to excessive rotation of the rotating body can be prevented.

A fitting portion is provided at the center of the top surface of the rotating body,
If the rotating body is configured to be rotationally operated via the operation lever that engages with the fitting portion, if the shape of the portion that engages with the fitting portion is common, the rotation operation can be performed even if the design of the operation lever changes. The electric parts can be shared, and the versatility of the rotary operation electric parts is increased.
