Abstract

PURPOSE:To obtain a safer electronic information apparatus by providing the apparatus with a locking mechanism engaged with both of an input function locking mechanism and a switching mechanism for an apparatus power supply. CONSTITUTION:At the time of moving sliders 31, 32 to a push rod 24 when the push rod 24 is depressed, a power supply switch is in the ON state and a key 34 is rotated by about 90 deg. to lock the key 34, the slider 31 is moved up to the uppermost end, but the slider 32 is abutted upon the side of the rod 24 and can not advance to the upper part. As the result, a spring 33 pushing up the slider 32 is compressed. When the head of the slider 32 is pressed and the spring 33 is compressed, input relating to a keyboard are stopped because the key 34 is rotated by 90 deg.. Even when the power supply is to be disconnected, the disconnection is impossible because the push rod 24 collides with the slider 31. Consequently, the safety of the electronic information apparatus is increased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a locking mechanism provided with a safety device for information equipment.

[Prior Art] Safety devices attached to general electronic information equipment are equipped with a safety mechanism that locks the input operation section when the operator leaves the equipment to prevent input by a third party. was. FIG. 6 is an external view of a device using a conventional safety mechanism, where 61 is an information device, and 62 is an input mechanism, such as a key lock mechanism for locking an input function such as a keyboard from operating. 63 is equipment 61
This is a power switch for. 64 is a floppy disk drive device.

[Problem to be Solved by the Invention] In the conventional configuration, as shown in FIG. 6, the power switch 63 and the key lock switch 62 are provided separately without any relationship, so the operator is not able to leave the equipment. In this case, the input function of the device is locked by locking the key 62, but if, for example, a third party accidentally or intentionally operates the most important power switch 63, the power will be cut off and the internal There is a risk that valuable data stored in the device may be lost, and even if the locking mechanism is used, it would be completely meaningless if only the data or command input function was locked. Therefore, an object of the present invention is to provide a safer electronic information device that prevents inconveniences such as inadvertently or maliciously erasing the memory contents of the device into which an immeasurably complex amount of information has been input. .

[Means for Solving the Problems] The present invention is characterized in that it includes a locking function that engages both a locking mechanism for an input function in an electronic information device and a power switch mechanism for the m-device.

[Embodiment] Fig. 1 is an external view of an embodiment of the present invention, in which 11 is an electronic information device incorporating a mechanism according to the present invention, 12 is a power switch, and the switch is located relatively close to the key lock switch 13. has been done. , 13 will be explained in detail from FIG. 2 onwards. 14 is a floppy disk drive device,
Functionally, it is not directly related to the present invention.

FIG. 2 shows the appearance of the key lock switch 13, with reference numeral 21 indicating a key lock switch section, 22 a key cylinder, 23 a power switch section, and 24 a bushing rod for the power switch.

Insert the key into the center of 22 and turn it 90 degrees to lock it. The internal structure will be explained below according to its movement.

FIG. 3(a) is an internal sectional view of the central part of the parts shown in FIG. 2, and common numbers such as 22 and 24 indicate the same parts. 31
is slider 1, 32 is slider 2, and spring 3
3 is always pushing up 32. FIG. 3(b) shows a state viewed from above, and shows a state in which the spring 33 pushes the slider 32 up to the top. Although the key 34 is not rotating and the power switch is in the "off" state,
Sliders 1 and 2 do not interfere with the operation of the power switch and can be turned on and off freely.

Figure 4 shows the power switch in the "off" state and the key 34
The key is locked after being rotated approximately 90 degrees.
1 and 32 have both moved upward to a position that obstructs the action of the bushing rod 24, making it impossible to push down the bushing rod 24 and turn on the power switch. FIGS. 4(a) and 4(b) are a sectional view and a plan view, respectively.

FIG. 5 shows a state in which the bushing rod 24 is pushed down, the power switch is turned on, and the key 34 is rotated approximately 90 degrees to lock the key.

Since the bushing rod 24 is being pushed down, when the sliders 1 and 2 move toward the bushing rod 24, the third member moves to the uppermost end, but the bushing rod 32 hits the side of the bushing rod 24 and cannot advance any further. As a result, the spring 33 pushing up 32 is compressed. Figure 5 (a), (b)
are a cross-sectional view and a plan view, respectively, as in Fig. 4, and Fig.
Figure (b) shows a state in which the head of the spring 32 is stuck and the spring 33 is compressed. Since the key 34 has been rotated 90 degrees, keyboard-related input is stopped.

At the same time, even if you try to turn off the power, Bush Rod 2
Since 4 is colliding with 31, the power cannot be turned off.

The reason for this is that in many pushbutton switch mechanisms, the power is turned on by pressing the button, and in order to turn the power off from the "on" state, when the button is pressed further and the finger is released, the button returns to its original position due to spring force. It is common for the power to be returned to the "off" state. In the structure used in the present invention, to return from the "alone" state to the "off" state, the bushing rod 24 is pushed deeper and then pulled back to cut off the power. However, the slider 24 is obstructed by the tip of the slider 1 of the slider 31 and cannot move. Therefore, it is not possible to turn off the power when the power is on.Although the present invention has been described using a bush switch type as an example, it is not limited to a switch mechanism with such a structure, and the same concept can be applied to other switches. It can also be fully applied to mechanisms.

[Effects of the Invention] The present invention locks input functions in order to increase the safety of electronic information equipment, and at the same time locks even the important power switch whether it is in the on or off state. It is an itemized mechanism.
