Definitions
- the present invention is an on / off switch for switching between two predetermined operations such as turning on / off and starting / stopping operation equipment, and is particularly suitable for a non-contact type switch having no plurality of contacts corresponding to the switching operation.
- the present invention relates to a non-contact type switch structure.
- On / off switches are widely used for switching between two predetermined operations, such as turning on / off and starting / stopping operating devices, and in recent years, they do not have multiple contacts for switching operations.
- Non-contact type switches are widely used.
- Various attempts have been made to improve the operability of the switch lever in the non-contact type switch.
- the present applicant has also proposed a non-contact type on / off switch that is disclosed in Japanese Patent Application Laid-Open No. 2009-26509 and includes a switch lever that can be tilted in any direction and has excellent operability.
- This non-contact type on / off switch is configured such that one end of a cylindrical material having flexibility and reversibly extending to a normal state is fixed to a base material, and a flexible bar material is inserted into the cylindrical body.
- One end is fixed to the end of the cylindrical member that is not fixed to the base material, and the other end is protruded from the cylindrical member. And when bending force is applied to the free end of the cylinder (the end where one end of the bar is fixed), the cylinder and the bar are bent, and the end of the bar protruding from the cylinder (moving) The end) moves in the direction of the free end along the axis of the bar or tilts relative to the axis. Since the movement of the moving end of the bar is the same regardless of the direction of the bending force applied to the free end, the movement of the end is converted into an electrical signal binary and output. In this case, the same output can be obtained regardless of the direction of the free end, that is, the on / off operation can be performed.
- the non-contact type on / off switch has a problem that it requires labor and cost to maintain.
- this reflection of light is used, the light receiving element is deteriorated due to deterioration of the reflection amount. Therefore, when the amount of reflection deteriorates, it becomes necessary to replace it, and it takes time and effort to maintain it.
- the present applicant has further proposed a switch lever structure of a non-contact type on / off switch disclosed in Japanese Patent Application Laid-Open No. 2010-123320.
- this switch lever structure one end of a bar is inserted and fixed to a flexible cylindrical body that can be restored to a normal state, and a mirror surface is formed on an end surface surrounded by the cylinder of the bar material.
- the detection part is arrange
- the present invention provides a non-contact type switch structure that can turn on / off electrical signals in a non-contact manner, can easily replace a worn part of an operation unit, and does not cause a decrease in sensitivity due to foreign matters such as dust. Objective.
- an opening is provided in an end surface of an exchange part that is detachable from an installation site, and a part of the end surface provided with the opening is a virtual boundary surface, and the exchange part is installed.

- the proximity arrangement means that the detection unit can detect the movement of the detection factor and is arranged with an interval that does not allow both to contact.
- the detection unit and the detection factor come into contact with each other, it is necessary to dispose the detection factor at a distance from each other because movement of the detection factor and attachment / detachment of the replacement unit with respect to the installation site are hindered.
- the interval is too large, there is a high possibility that foreign matters such as dust will be present in the gap, and the detection sensitivity of the detection unit will be low, so it is preferable to keep the interval as small as possible.
- the movement of the detection factor in the direction parallel to the virtual boundary surface does not deny the movement of the virtual boundary surface in the normal direction.
- the detection factor is a range that does not protrude from the virtual boundary surface toward the installation site, it may move in the normal direction simultaneously with the direction parallel to the virtual boundary surface. For example, it may move in a direction away from the virtual boundary surface and away from the detection unit, that is, in an oblique direction from the normal position of the exchange unit toward the bar.

- the detection factor moves from the virtual boundary surface in the direction parallel to the virtual boundary surface on the exchange unit side, and the detection unit detects that the detection factor is separated. That is, since the presence or absence of the switch operation can be detected in a non-contact manner, the electrical signal can be turned on and off in a non-contact manner.
- the detection factor involved in the detection of the presence or absence of the switch operation is that when the bar attached to the free end of the flexible cylindrical body is operated, the base of the bar together with the swinging member extending from the base end of the bar. Swings around the end as a fulcrum.
- the moving range is restricted from the virtual boundary surface (the portion provided with the opening on the end surface) of the replacement unit end surface to the replacement unit side. That is, the detection factor moves in the direction parallel to the virtual boundary surface on the exchange part side from the virtual boundary surface, and does not protrude from the virtual boundary surface. Therefore, the replacement part can be easily attached to and detached from the installation site, and the wear part included in the replacement part can be easily replaced as the whole replacement part. Furthermore, since the detection factor and the detection unit involved in the detection of the presence / absence of the switch operation are arranged close to each other across the virtual boundary surface, foreign matter such as dust is prevented between them, and the sensitivity is reduced due to the foreign matter. There is nothing.
- the detection unit is any of magnetic force, light amount, volume, inductance (L), capacitance (C). Even those that make use of changes are all corresponding to these. Therefore, it can be replaced regardless of the detection principle of the detection unit.
- the detection factor and the detection unit can be reliably arranged close to each other by including a holding unit that holds the detection factor or a part of the swinging member at a predetermined position in the normal state of the replacement unit. For this reason, when the replacement unit is installed, it is possible to prevent a malfunction caused by the positional deviation between the detection factor and the detection unit.
