Abstract

PURPOSE:To store generated energy in a built-in battery so as to continuously operate a power generation switch for a long time by means of the battery by inserting and extracting a rod-like permanent magnet which is interlocked with a push-button into and from a coil by pushing the push-button. CONSTITUTION:When a push-button 1 is pressed, a switch section 2 is actuated and, at the same time, a permanent magnet shaft 1 is inserted into and extracted from a power generation coil 3. As a result, electromotive forces are generated across both ends of the coil 3 by Fleming's rule. Since the polarity of the electromotive forces of a power generating section 3a to a battery 5 is alternately inverted when the button 1 is pressed and released, a rectifier (circuit 6 is required. Because of the operation of the button 1, the switch section 2 is used as a switch for another electric circuit. The operating work of portable OA equipment is mainly composed of keyboard operation and it is said that the operating frequency of keyboards reaches several hundreds to several thousands of times per hour. In addition, the battery 5 can also be charged when this power generation switch is connected to a keyboard.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generation switch, and more particularly to a power generation switch suitable for charging a battery of a battery-sized OA device such as a book size personal computer or a word processor.

[0002]

2. Description of the Related Art Conventionally, as a power source of a battery built-in type OA device, a primary battery or a secondary battery is generally used. This OA device does not have a device with a built-in charger, especially when it is portable, and is generally converted to a battery or recharged at a fixed place.

[0003]

Since the above-mentioned conventional battery-installed OA equipment does not have a power generation mechanism,
There is a drawback in that the work must be interrupted because the battery capacity is exhausted after a certain period of use and the battery must be recharged or the battery must be replaced.

[0004]

A power generation switch according to the present invention comprises a push button, a rod-shaped permanent magnet that interlocks with the push button, a coil capable of putting the permanent magnet in and out, and the push button. The switch has an interlocking switch, and when the push button is pressed, a constant electromotive force is generated in the coil.

[0005]

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is an application circuit diagram to which the present embodiment is applied.

In FIG. 1, when the push button 1 is pushed, the switch portion 2 is operated, and at the same time, the permanent magnet shaft 4 is put into and taken out of the generator coil 3. At this time, electromotive force is generated at both terminals of the magneto coil 3 according to Fleming's right hand rule. FIG. 2 is an example in which the power generation switch of this embodiment is applied as a battery charging power source. Since the polarity of the electromotive force to the battery 5 of the power generation unit 3A is inverted when the push button 1 is pressed and released, the rectifier circuit 6 is required. The switch unit 2 is used as a switch for another electric circuit by the operation of the push button 1. In addition,
It is said that the keyboard operation is the main operation of the portable OA equipment, and the number of times is several hundreds to several thousands per hour. Therefore, charging can be performed at the same time by connecting the keyboard and the power generation switch.

[0007]

As described above, the power generation switch of the present invention can generate power only by including the permanent magnet and the coil.
Laborsaving of notebook type OA equipment etc., which is currently expanding significantly, will be realized. By storing this energy in the built-in battery, there is an effect that it can be operated continuously for a long time by the battery drive. Furthermore, the development of low power consumption technology for electronic devices will enable semi-permanent operation in the near future.
