Abstract

PURPOSE:To ground the static electricity of a human body which cause the majority of electrostatic trouble during operation by providing a conductive member which is grounded to an operation part itself or nearby. CONSTITUTION:The metallic conductive member 4 is embedded in the surface of a recessed part 3 near a power supply switch 1 and grounded through an earth wire. An operator should operates the power supply switch 1 when turning on electric equipment 2, but the static electricity of the human body is discharged to the ground through the conductive member 4 that the operator contacts. When the switch uses a push-button key 9 like a ten-key, its key top 10 itself is made of a metallic conductive member and grounded through the earth wire 11.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to electronic office equipment having electronic processing functions.

BACKGROUND OF THE INVENTION In recent years, various devices of this type, such as electric typewriters, word processors, office computers, personal computers, microcomputers, and cash registers, have become popular. .

In this type of electronic office equipment, static electricity is harmful and countermeasures against static electricity are taken. However, when we look at countermeasures against this, noise countermeasures are implemented with CR circuits in keyboards, etc., and cables are shielded.
Measures are taken to address all aspects of the target office equipment that are thought to be susceptible to static electricity, which increases costs.

the purpose The present invention was made in view of these points.

The purpose is to obtain electronic office equipment that can easily and reliably take measures against static electricity.

Structure A first embodiment of the present invention will be described based on FIGS. 1 and 2. Generally, electronic office equipment has a power switch, so in this embodiment, this power switch 1 is used as the operation section, and this power switch 1 is used as the electronic office equipment 2.
Instead of being attached to the surface of the holder, it is placed inside the recess 3 and is attached at a position one level deeper than the surface. However,
A metal conductive member 4 is embedded in the surface of a portion of the recess 3 near the power switch 1. This conductive member 4 has a thickness t of approximately 10 m, and is grounded by a ground wire 5.

In such a configuration, the operator always operates the power switch 1 to turn on the power before operating the electronic office equipment 2. At this time, the power switch 11
is arranged at a recessed position, and the finger comes into contact with the conductive member 4 when operating it. When the finger comes into contact with the conductive member 4 in this manner, static electricity accumulated in the operator's body flows to the ground via the conductive member and the ground wire 5.

The operator is therefore electrically neutral and the possibility of future discharge from the operator is reduced.

In other words, this embodiment focuses on the fact that more than 90% of static electricity damage to electronic office equipment 2 is thought to be caused by discharge from the human body, and instead of taking static electricity countermeasures after the fact as in the past. , to remove static electricity from the operator before operating the electronic office equipment 2. By taking such fundamental measures, there is a very low possibility that the electronic office equipment 2 will malfunction due to electric discharge from the operator in the future.

Next, a second embodiment of the present invention will be described with reference to FIGS. 3 and 4. This embodiment was developed by focusing on the fact that many electronic office equipment are equipped with a keyboard section 8 consisting of an A/N keyboard 6, a numeric keypad section 7, etc., as shown in FIG. The key top 10 of each key 9 serving as an operating section is made of a metal conductive member and is grounded by a ground wire 11. 12 is a key chain, 13 is a switch body that resists the spring 14 and holds the key top 10
By pressing , the contact 15 can be contacted.

According to such a configuration, the operator can use the keyboard section 8.
If your finger touches any key top 10 during operation,
Static electricity accumulated in the operator's body flows to the ground via the metal key top 10 and the ground wire 11. Therefore, as long as the operator operates the keyboard section 8 and touches the key tops 10, static electricity always escapes to the ground, and the operator is kept in an electrically neutral state. Therefore, there is no possibility of electrical discharge from the operator, and countermeasures against static electricity are reliable, and malfunctions do not occur. Further, even if the operator touches other electronic office equipment, no discharge occurs, so it can be expected to have a static electricity prevention effect on other electronic office equipment.

In this embodiment, the key top 10 is made of metal, but it may also be made of metal plating, zinc spray paint, or the like. Also, the earth wire 11 is omitted and the key chain 12 is used.
It is also possible to ground the key top 10, and when the key top 10 is pressed, the 0 point and the ■ point come into contact, thereby allowing static electricity to escape.

Furthermore, a third embodiment of the present invention will be explained with reference to FIGS. 5 and 6. In this embodiment, a conductive plate 16 as a conductive member is provided at a portion that is easily touched by the operator's palm when operating the keyboard portion 8. This conductive plate 16 is grounded. Therefore, when operating the keyboard section 8, the operator's palm comes into contact with the conductive plate 16, and static electricity is dissipated to the ground. Here, as shown in FIG. 6, if the conductive member plate 16 is set to the height of the key tops of the A/N keyboard 6, etc., the operator's operability will be further improved.

Effects Since the present invention is configured as described above, the static electricity from the human body, which accounts for most of the static electricity hazards during operation, can be dissipated to the ground, and such fundamental measures can easily and reliably prevent the negative effects of static electricity. It is something that can be done.
