Abstract

PURPOSE:To fetch all control operations of a push-pull rotation, as an electric signal, by containing a contact mechanism and a rotation detecting mechanism in the inside of a knob. CONSTITUTION:In case a control 1 has been pushed, a spacer S of the upper side is depressed downward, a contact 3a of a microswitch 3 of the left side is depressed, and a contact signal of a push is outputted. In case the control 1 has been pulled, a spacer S of the lower side is pushed up, a contact of a microswitch 3 of the right side is pushed up, and a contact signal of a pull is outputted. In case the control 1 has been rotated, a pattern band 1a is rotated, and a pulse being proportional to a rotational angle by a variation of a reflected light is outputted from an opposed photointerrupter 5.

Description

[Detailed Description of the Invention] Industrial Application Fields The present invention is capable of outputting a contact signal during push/pull and rotational operations of a knob, and a pulse signal, for example, during rotational operation. The present invention relates to a multi-functional knob with possible multi-functional performance.

<Prior art> There is no known multi-function knob of this type in the past, and generally there is a contact signal when pushing and a contact signal when pulling.

Pulse signals and the like during rotational operation were obtained by operating switch mechanisms, rotary encoders, etc., which were provided individually for each function.

<Problems to be solved by the invention> However, when attaching switch mechanisms, rotary encoders, etc. for each function to the main body of the device, for example,
The space factor within the main body becomes worse, making it difficult to design the outer casing of the device, for example. For example, when assembling a large number of small precision devices such as aircraft equipment, etc., the
There was a problem that it was difficult to set up i+.

The present invention has been made in view of the problems of the prior art, and includes a contact mechanism that operates by push/pull and a rotation detection mechanism that detects displacement due to rotation, which were conventionally provided individually. The purpose of the present invention is to provide a multifunctional knob that is compact as an integrated unit, ensures space saving, and can be used even when there is no room for installation.

<Means for solving the problem 2. The multi-functional knob of the present invention to achieve the above-mentioned object has the following features:
A knob with patterned bands with different reflectances on the inner circumference is attached to the mounting shaft so that it can freely move up and down nine rotations, and inside this knob there is a contact mechanism that operates when pushing and pulling the knob on the mounting shaft, and a contact mechanism that operates when the knob is rotated. At the same time, a detection element of a rotation detection mechanism for detecting the direction of rotation from the reflectance of the pattern band is installed, and when no external force for push-pull operation is applied to this knob, the contact mechanism is set so that the position is not activated. It is characterized in that it is held at a neutral position.

<Example> An embodiment of the present invention will be described in detail below based on the drawings.

The figure is a configuration diagram of the multi-functional knob of the present invention, especially figure (A).
) is a top view of the x-X section in Figure (B), Figure (B)
is a front view of the YY section in FIG.

In the figure, reference numeral 1 denotes a knob with a striped pattern band 1a for encoding consisting of, for example, a white and black arrangement structure with different reflectances on the upper and lower parts of the inner circumference, and a spacer) J on the mounting shaft 2. -8, and can be moved linearly up and down (arrow direction α) along the mounting shaft 2 after assembly, and can also be rotated (arrow β). 3 is housed inside the knob 1 and is attached to the mounting shaft 2 with a single female screw 4, so that when the knob 1 is pushed or pulled, the rotation 11-
This is a contact mechanism consisting of, for example, a microswitch that outputs a contact output from a contact 3a that is turned on or off via a spacer S provided with a claw portion S1. In addition, in such a configuration, if the claw portion S1 is not provided, when the knob 1 is turned, the spacer S may also rotate together and be displaced from the contact point 3a. Reference numeral 5 indicates a rotation detection mechanism (for example, a photo interrupter) that is attached to the mounting shaft 2 at a vertical position opposite to the pattern band 1a and detects the rotation direction from the reflectance of the pattern band 1a that moves with the rotation of the knob 1. Detection mechanism 5 and pattern band 1
A detection element 6 is provided at the upper and lower positions of the mounting shaft 2, and when no external force is applied to the knob 1 such as push/pull operation, the sensor element 6 is located between the spacer = S position and the contact point 3a. This is a holder made of, for example, a spring, which maintains a certain space between the knobs 1 and 1, that is, maintains the position of the knob 1 in a neutral state.

With this configuration, when the knob 1 is pressed, the + side spacer S is pushed down, and for example, the contact 3a of the microswitch 3 on the left side of the figure is pushed down,
When knob 1 is pulled, the lower spacer S is pushed upward, and for example, the contact of the fibro switch 3 on the right side of the figure is pushed up and a contact signal is output, and when knob 1 is rotated, the pattern band 1a is pushed up. rotates, and the opposing photointerrupter 5 outputs a pulse signal proportional to the rotation angle due to changes in reflected light.

However, the present invention is not limited to the configuration shown in the figures.

For example, the reason why two-phase encoders consisting of the pattern band 1a and the photointerrupter 5 are provided at the top and bottom is to create different rotational direction signals by shifting the phases of the encoder outputs by 90 degrees. Obi 1a
7. It is not necessary to separately provide the interoperator 5 by dividing it into upper and lower parts as shown in the figure. For example, install a pair of photo interrupters 5 in opposite directions above the mounting shaft.
The same output as above using two (-upper) pattern bands is 1q
It can also be configured so that

Further, the positions of the spacers S, springs, etc. can be changed or omitted as necessary. For example, by providing a part equivalent to a spacer inside the knob, there is no need to provide a separate spacer, or by placing the upper spring in the space between the upper end of the shaft and the inside of the knob, and placing the lower spring in the upper end of the shaft and the space inside the knob. It can also be installed between the lower end of the knob and the flange of the mounting shaft.
The settings can also be easily changed.

<Effects of the Invention> As described above, the present invention has been specifically explained along with the examples.
According to the multifunctional knob of the present invention, which accommodates a contact mechanism and a rotation detection mechanism inside the knob and can extract all III and III operations such as push, pull, and rotation as electrical signals, the device that uses these signals can There is no need to provide a special mechanism or space for the machine, so it is easy to downsize the entire device, and work is made easier in terms of stack weight, etc. . In addition, with this structure, other parts can be easily placed on the back side of the panel where the knob is installed on the equipment side, and the knob installation position can be freely selected, improving the operability of the entire equipment.
This has the effect of giving priority to design and improving the quality of equipment.
