Abstract

PROBLEM TO BE SOLVED: To provide a manual operation switch that prevents camera shake by operating the switch by the position of a finger without applying pressing force and that also prevents improper operation by providing a standby position closest to a detection position and placing a finger tip there to stabilize.SOLUTION: A switch is a proximity switch 5 that operates when an object such as a magnet and metal comes close, and an operation piece made of a small piece of magnet, metal or the like is attached to a fingertip. A standby position with a shape such as a concave or convex is formed closest to the switch 5, and a user waits placing the operation piece at the fingertip on the standby position. Next, the user moves it to an operational position and performs ON operation and moves it to the standby position when performing OFF operation.

Description

The present invention relates to a manually operated switch for turning on / off electrical signals of devices and the like.

Conventionally, when operating a switch installed on a handheld device such as an electric pen, hand dispenser, electric knife, etc., with the fingertip, the tip of the handheld device is swung away from the target position and scratches or the color protrudes. . The camera shutter also causes camera shake. This occurs because the operating force of the switch is unexpectedly large. If the operation force is small, it will be turned ON / OFF just by touching the switch, so the pressing force is slightly increased. Also, it is often the case that a light finger is placed on the switch just before pressing to wait, but it is difficult to adjust the force. If the waiting time is long, the finger gets tired and the switch is accidentally pressed.

Problems to be solved by the invention

The switch is operated according to the position of the fingertip without applying a pressing force to prevent camera shake.
Also, a standby position is provided in the immediate vicinity of the detection position, and a fingertip is placed on the standby position to stabilize and prevent erroneous operation.

Means for solving the problem

In the present invention, the switch is a proximity switch that operates by the proximity of a magnet, metal, or the like, and an operation piece made of a small piece of magnet, metal, or the like is attached to the fingertip. Or it detects by the touch of a fingertip as a touch switch.
A standby position such as a concave or convex shape or a planar shape is formed in the immediate vicinity of the detection position, and the fingertip or the operation piece of the fingertip is placed at the standby position to wait. Next, it is moved to the detection position and turned on, and when it is turned off, it moves to the standby position.

The switch for hand dispensers will be described in detail. The hand dispenser 1 discharges the liquid in the syringe 2 from the nozzle 3 at the tip of the syringe, and uses it for coloring engraving characters, bonding fine parts, and the like. The switch 4 attaches a proximity switch 5 that reacts with the approach of metal to the mount 6. A magic tape band 7 is provided on the lower surface of the mounting base 6 and is wound around and fixed to the syringe 2. An end connector 9 of the lead wire 8 of the proximity switch 5 is connected to a controller that controls the liquid and sends a signal of the switch 4. The metal piece 10 is attached to the fingertip with an adhesive. The proximity switch 5 has a square shape and uses the cross surface 11 as a detection surface.

Action

When the metal piece 10 of the fingertip comes into contact with the corner portion 12 (non-detection portion) of the proximity switch 5 and waits, and when the fingertip is shifted and brought into contact with the cross surface 11, the switch is turned on and the liquid is discharged. When the switch is ON, the operation lamp of the proximity switch 5 is lit to confirm that the switch is ON. When the switch is off, the switch is turned off when the fingertip is slightly lifted.
The operation range of the proximity switch 5 is selected to be several millimeters.

effect

The switch can be operated with a slight movement of the fingertip without the need for pressing pressure and shaking.

Since the fingertip is held with the corner portion 12 (non-detection portion) of the proximity switch 5 as the standby position, it is possible to prevent the fingertip from shaking and performing an ON operation during the standby time until ON.

The proximity switch 5 can be applied as a commercial product, can be easily retrofitted to the outer periphery, and can be waterproofed without exposing the mechanical operating part. The structure is simple and can be provided at low cost. Since the commercially available proximity switch 5 has a 90 ° angle between the detection surface and the side surface, the metal piece 10 is easily caught. It is good to form it diagonally and to make the movement of the metal piece 10 smooth.

The underwater camera shutter will be described in detail. The underwater camera shutter is heavy enough to withstand water pressure. Some cases have a lever that can be moved lightly. In addition, gloves are often worn underwater, and it takes time to check the shutter position and misses a photo opportunity or causes camera shake.

The camera 20 is configured so that the shutter 21 operates as a proximity switch and is turned on. The dish-shaped detection unit 22 does not operate when the metal button 24 for operation is placed on the dish-shaped edge projection 23 serving as a standby position, and turns ON when placed on the dish bottom 25. The metal button 24 is formed of a dish-shaped metal plate and is sewn to the fingertip 26 of the glove. Metal cloth and metal foil may be sewn. Or it is good also as a detachable ring form. It is also possible to install another proximity switch on the projection 23 to detect the standby position.

Action

The metal button 24 is put on the projection 23 and waits. When the fingertip is moved and the metal button 24 is placed on the dish bottom 25, the shutter 21 is turned on. It is convenient to display the standby position in the viewfinder.

effect

Even when the body is shaking due to the shaking of the waves, the shutter can be easily operated because the fingertip can be securely fixed at the standby position.

Since there are no movable parts, the protrusion 23 and the dish bottom part 25 can be formed in any shape and can be easily operated even when wearing underwater gloves. Since the movable part as the shutter is not exposed, it can withstand high water pressure and deepen the depth.

The hand switch of the electric knife is described in detail. When treating thin blood vessels, nerves, small pathological parts, etc. with an electric scalpel (including laser scalpels, ultrasonic scalpels, etc.) used for medical purposes, if the scalpel part moves by the force of pressing the hand switch, the treatment position is wrong. There is a light hand switch of the touch switch type, but it gets tired to wait with the finger floating on the switch before pressing.

The electric knife 30 has a protrusion 31 with an oval contour on the outer periphery, a standby position 32 is formed on the dish bottom 34 on the inner left side of the protrusion 31, and a hand switch 33 is formed on the dish bottom 35 on the inner right side of the protrusion 31. ing.
The dish bottom 35 is adjacent to the dish bottom 34, and the dish bottom 35 is formed slightly deeper than the dish bottom 34. The hand switch 33 has a proximity switch configuration. The surgeon wears a metal ring 37 on the fingertip of the surgical glove 36.
Forming a loose arcuate protrusion at the center of the metal ring 37 is easy to operate.

Action

When the surgeon firmly touches the metal ring 37 against the dish bottom 34 serving as the standby position 32, attaches the scalpel tip to the surgical site, and then slides the metal ring 37 onto the dish bottom 35, the hand switch 33 is turned on. When turning OFF, the metal ring 37 is slid on the dish bottom 34 and moved. Even if the detection distance of the proximity switch is selected and it is close to the detection surface without touching, it can be operated.

effect

The ON / OFF operation of the hand switch 33 can be performed by sliding the fingertip, the knife tip hardly moves, and it is possible to prevent the treatment position from being mistaken. At the standby position 32, it is not necessary to lift the finger, the electric knife 30 can be securely held, and the finger is not tired.

Another proximity switch is also formed at the standby position 32, and at the standby position, the operator can be alerted by making an identification buzzer sound.

As a proximity switch, it has been described in detail as a proximity switch that operates by the proximity of a magnet, metal, etc., but it is also possible to eliminate the metal piece of the fingertip as a touch switch or photo switch, and the standby position and switch position are identified by unevenness and the fingertip is slid This is characterized in that it is operated by changing the position to prevent malfunction.
When a large number of switches such as a touch panel are arranged, the boundary between adjacent switches is ambiguous and a push error occurs. The same effect can be obtained by placing a thin partition sheet at the boundary and setting it as the standby position. In addition, since it is easy to operate even with thick gloves, it can be applied to switches for preventing malfunctions in special working environments such as switches for chemical factories, nuclear reactors, spacecrafts, etc. Since it does not require a pressing force for operation, it can be adapted for a disabled person who cannot press.

The detection surface of the conventional proximity switch is formed by a simple plane. A proximity switch having a detection surface convenient for operation with a metal piece on the fingertip will be described in detail. The proximity switch 40 has a standby position 42 and a detection position 43 on the detection surface 41, and each is formed by a dish-shaped recess. A mounting hole 45 is formed in the mounting surface 44. If the detection position 43 is slightly deeper than the standby position 42, the operation becomes easy.

Action

The proximity switch 40 is attached to the outer periphery of the handheld device by inserting a screw through the attachment hole 45. A metal piece attached to the fingertip is placed at the standby position 42 to stand by, and the fingertip is slid when the switch is operated to place or approach the metal piece at the detection position 43. If the proximity switch is a touch switch, it can be operated without a metal piece.

effect

The structure of the handheld device is simplified because it can be attached later without making a dedicated switch on the handheld device. Easy to replace in case of switch failure. It can be applied to machine operation as well as manual operation. The detection surface can be applied not only to dish-shaped dents but also to various types such as corners, triangles and kamaboko shapes.

Detailed metal pieces that are easy to put on the fingertips. The metal piece 50 has a disk-like shape, and the surface 51 attached to the fingertip is on the concave spherical surface side, and the switch detection surface 52 is on the convex spherical surface side. Means such as applying an adhesive to the affixing surface 51 or installing a sewing hole for a glove is applied. When the proximity switch is a magnet switch, the metal piece 50 is formed of a magnet. It is possible to prevent the NS pole from being mistaken. Can be manufactured at low cost. The convex spherical surface of the switch detection surface 52 makes the switch surface slippery and easy to operate. It is easy to form a resin ring and fit the metal piece 50 in the center. If the switch detection surface 52 is formed into a convex spherical surface, the detection position becomes narrow and a reliable response position can be determined. This makes it possible to determine the detection position by using a proximity switch operating piece for mechanical operation as a convex surface such as a sphere, a triangle, or a kamaboko shape. (If the operation piece is made of a flat plate, you may not know where it will be detected, so it may be marked with a scale.)

In the first embodiment, the proximity switch 5 is a commercially available square switch. However, since the standby position and the detection position are not formed, some skill is required for operation. The proximity switch case in which the standby position and the detection position are formed will be described in detail. In the proximity switch case 60, a standby position 62 and a detection position 63 are formed on the surface of the outer skin 61, an insertion hole 65 for the proximity switch 64 is formed inside, and attachment slits 67 for attaching the magic tape 66 are formed on both side surfaces.

Action

The proximity switch 64 is inserted into the insertion hole 65 so that the detection position 63 and the detection position of the proximity switch 64 coincide. Attach Velcro 66 to the outer periphery of the handheld device.

effect

Commercially available square switches can be applied, and can be mounted on thin parts where mounting screw holes are difficult to install.
When the mounting hole can be installed, the installation of the magic tape 66 or the like can be omitted. Although the insertion hole 65 is formed, it is good also as a shape which covers the upper surface of a commercially available square switch. It is also possible to install a groove or the like for mounting the switch case on the side surface of the square switch.
