Description

  The present invention relates to a device for preventing erroneous operation of a power switch of an electronic device or an electronic device.

  Currently, many electronic devices such as information processing apparatuses and communication control apparatuses have a power switch for turning on / off (turning on / off) the power. Normally, when only a simple on / off function is required, a toggle switch, a push switch, a key switch, a wave rocker switch, or the like is used as a power switch.

  When incorporated in a so-called control panel or control console, a toggle switch, push switch, key switch or the like is often used as a power switch, but a general office such as OA equipment, information processing, communication control equipment, etc. In the case of a device installed in a similar manner, a waveform rocker type switch is overwhelmingly used in terms of its appearance, structure, size, and the like. An example of a standard wave type rocker switch for power supply that is commercially available is shown in FIG. (A), (b) is a perspective view of the wave type rocker switch 1, (c) is a top view, (d) is a front view, (e) is a side view. In the figure, 2 is a rectangular parallelepiped body part, 3 is a switch part, and 4 is a connection terminal.

As described above, the wave-type rocker switch 1 is used as a standard in a power on / off mechanism for information equipment, etc., and the wave-type rocker switch 1 has few protrusions and is aesthetically pleasing for simple power on / off operation. It is excellent in that it is excellent, has a gentle operation feeling, and is relatively inexpensive. Some rocker switches are described in Patent Document 1 and Patent Document 2.

  However, consider a case where the device used by the power switch has a special condition regarding the operability of the switch. For example, “This device is always on and must be turned off with contact with a person or an object in order to use the device.” The power switch must be on the front panel. ”And“ No one should be able to operate it like a key switch. This is a case where the condition “It must be possible” is given simultaneously.

  That is, the power switch must be on the front side and can be operated by anyone, but it must not be structured so that it can be easily turned off by mistake. Conventionally, a toggle switch with a lock mechanism has been developed in order to solve such a conflicting proposition. FIG. 8A is a perspective view of the toggle switch 5 with a lock mechanism, and FIG. 8B shows an operation method thereof. The toggle switch 5 includes a main body 6, a toggle lever 7 and a connection terminal 8. It is movable in the vertical direction. When the toggle lever 7 is pulled, the toggle lever 7 can be toggled and the power switch can be turned on and off. However, when the toggle lever 7 is released, the toggle lever 7 returns to its original state due to the springiness. And cannot be toggled, and the power switch cannot be turned on or off.

  FIG. 9 is a diagram for explaining the operation of the locking mechanism of the toggle switch 5 with a locking mechanism. When the claw 7a of the toggle lever 7 and the claw or groove on the main body 6 side mesh with each other, the normal toggle lever 7 is retracted (lowered). In this state, it is latched in any toggle state and cannot be toggled. However, when this latch is released by pulling (lifting) the toggle lever 7, the toggle lever 7 can be reversed (toggled). . As described above, when the toggle switch 5 with the lock mechanism is used, the toggle lever 7 does not reverse unless the operator dares to pull the toggle lever 7 and then performs the on / off operation. Must not be performed. " In addition, since the toggle operation after pulling the toggle lever 7 is an operation that can be performed by anyone, it should not be operated only by a specific person such as a key switch. It must meet the condition of “Must be.” In other words, the previous proposition can be solved by using this toggle switch with a lock mechanism.

  However, toggle switches with large protrusions and a strong overall control panel image are not suitable for information equipment, communication equipment, etc. placed in a general office environment. Therefore, it is required to solve the above-mentioned proposition for such devices on the assumption that a wave-type rocker switch is used. With regard to this proposition, the applicant has tried many times in the past to try to solve it, and there is a need to solve it now or in the future. FIGS. 10A and 10B show an example of the solution. When the wave-type rocker switch 1 is attached to the housing-type attachment member 8, an erroneous operation preventing member 9 is interposed between the two. . That is, as shown in FIG. 10A, the erroneous operation preventing member 9 is formed in a U shape having side portions 9b on both sides in the horizontal direction of the central portion 9a, and is slightly wider than the main body portion 2 of the corrugated rocker switch 1. The wide central portion 9a has a rectangular insertion hole 9c that is slightly smaller than the main body portion 2 of the corrugated rocker switch 1, and the attachment member 8 also has an attachment hole 8a having substantially the same size as the insertion hole 9c. And as shown in FIG.10 (b), the main-body part 2 of the wave type rocker switch 1 is inserted by the insertion hole 9c and the attachment hole 8a, and is integrated.

  When the wave type rocker switch 1 is attached to the attachment member 8 as shown in FIG. 10B, the human finger to operate is turned on / off only when the human finger is operated along the central portion 9a of the erroneous operation preventing member 9. If a hand or other object is likely to come into contact with the rocker switch 1 due to an operation, both sides 9b of the erroneous operation preventing member 9 serve as a guard, and the hand or object touches the rocker switch 1. To prevent. Thus, the erroneous operation of ON / OFF due to the contact with the rocker switch 1 can be prevented by the both side portions 9b of the erroneous operation preventing member 9 which is a simple mechanism. Accordingly, the applicant frequently uses the erroneous operation preventing member 9 for the wave rocker switch 1 as a power switch for information equipment, communication equipment, and the like.

  However, even when such an erroneous operation preventing member 9 is used, when a human hand enters the central portion 9a, it has no guard function at all. Alternatively, it is impossible to lock it if it “operates accidentally”. In that sense, the reality is that there is still no complete answer to the proposition we have taken up this time.

  The present invention has been made to solve the above-described problems. By requiring two behaviors from the operator, it has a function of preventing erroneous operation and providing a full-safe function with a simple and inexpensive structure.
