Abstract

PROBLEM TO BE SOLVED: To provide radio type push button illumination unit in which when an object stored in a storage rack or storage box is instructed to be shipped, carried out, etc., the address of this object can be visually confirmed by illumination of the LED of a light source displayed in the vicinity of the object and can be fetched quickly. SOLUTION: A radio type push button illumination unit comprising a parent machine (transmission unit) 1 capable of oscillating weak electric waves and a children machine (receiving unit) 4 capable of receiving this electric wave with an LED 7 which illuminates during reception to enable the lighting LED to be visually confirmed, one parent machine (transmission unit) 1 to restore by pushing a push button switch 6 mounted on the children machine (receiving unit) 4 after the confirmation, and a number of children machines (receiving units) in which an instruction is given by pushing the push button switch 3 of a number to be instructed, provided for the parent machine (transmission unit) 1, and the LED 7 of the children machine (receiving unit) of the same number is lit and illuminated by means of the weak electric waves.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention According to the present invention, an LED 7 of a slave unit (reception unit) 4 in which a storage shelf, a storage box, a storage item, etc. of an article to be carried out is installed is a base unit (transmission unit). (Unit) 1 is illuminated by the command, so that visual control can be done quickly, and the items that require the work of various conveyor lines in the process are illuminated by the LED 7 according to the command.
This is a wireless push-button illumination unit that has a wide range of use because it makes it easy to see what to take out.

[0002]

2. Description of the Related Art Conventionally, in order to carry out articles, articles arranged in various shelves or in a storage box are carried out by a wired circuit from a control panel by a motor drive or the like in response to a wired instruction.

[0003]

However, for each shelf or for each storage box, it is necessary to search for and take out a specific necessary article among them, and the present invention solves the above-mentioned problems and a new wireless type It is intended to provide a push button illumination unit.

[0004]

The present invention comprises a combination of a master unit (transmitting unit) 1 and a large number of slave units (receiving units) 4 by utilizing weak radio waves, and the master unit (transmitting unit) (Unit) 1 and a slave unit (reception unit) 4, and a push button switch 3 for giving an instruction to the location, or an instruction previously input to a separately installed personal computer is combined with the base unit (transmitting unit) 1. By means of the means, the wireless push button illumination unit that solves the above problems by illuminating the LED 7 of the slave unit (reception unit) 4 is obtained.

[0005]

The system of the wireless push button illumination unit having the structure as described in the preceding paragraph has a slave unit (reception unit) in which various items are installed near the storage location from the master unit (transmission unit) 1 by weak radio waves. ) 4, the necessary items are instructed, the command is transmitted, and the illuminated LED 7 attached to the child device (reception unit) 4 is turned on to instruct the delivery of the article.

[0006]

EXAMPLE An example of the present invention will be described below.
FIG. 1 is a schematic configuration diagram of a wireless push-button illumination unit according to an embodiment of the present invention. A radio wave used for the wireless communication of the present invention uses any one channel out of ten channels of 48 MHz band for transmission. The electric field strength of the electric wave uses a weak electric wave of less than 500 μV / m at a distance of 3 meters, and the receiving method uses the double superheterodyne method.
FIG. 1 is a schematic configuration diagram of the present invention, in which a transmission antenna 2 of a master unit (transmission unit) 1 and a reception antenna 5 of a slave unit (reception unit) 4 installed in advance nearer to an article are shown. After receiving the light, the LED 7 is illuminated, and after visually confirming, the LED 7 of the child device (reception unit) 4,
Press the push button switch 6 to restore so that the next work can be performed. Hereinafter, similarly, for a necessary item, the slave unit (reception unit) 4 is transmitted from the master unit (transmission unit) 1, The LED 7 of the slave unit (reception unit) 4 is instructed to light up, FIG. 2 is the master unit (transmission unit) of the present invention.
FIG. 3 is a systematic block diagram showing an electric circuit of FIG.
FIG. 3 is a systematic block diagram showing an electric circuit of the slave unit (reception unit) 4 of the present invention. Further, the reception unit is not microcomputer controlled in the standby state, and a dedicated logic circuit is separately added. , This circuit controls the opening and closing of the receiving part to reduce the power consumption of the power supply battery.

[0007]

As described above, although the present invention has an extremely simple structure, it has an extremely effective function that enables easy visual inspection work for an instruction to carry out, such as taking out articles, without error. This is also a great feature, and since the present invention can be manufactured inexpensively with a small device, it is also a practical advantage that a large number of distribution arrangements can be made.
