Abstract

PURPOSE:To find easily a target by providing the target to be retrieved with a receiver capable of identifying a preset code. CONSTITUTION:Where plural of commodities, cases and files are contained at random, all of them are provided with receivers capable of identifying a code signal transmitted from a transmitter to the commodities, cases and files. For instance, the receiver equipped with a light receiving element 10 is built-in each file 9. When the code of the target file is inputted through a keyboard from an input 1, a signal enters all light receiving elements 10 on the file placed at randam by a code generation 2 and a transmission 3 with an infrared ray emitting element 8. Only a display lamp 6 on the file coincident with the input code lights up to find easily the target file. After the file is taken out, the system is reset 7 and turns off the display lamp 6.

Description

DETAILED DESCRIPTION OF THE INVENTION 0) Industrial Application Field This invention relates to a search system that can easily find a large number of randomly stored items, cases, files, etc.

(b) Conventional technology In the past, many automatic warehouses using combinators and mechanical output mechanisms were large-scale and economically large-scale.

(c) Problems to be solved by the invention The invention was invented as a relatively small-scale and inexpensive search system.

2) Means for solving the problem The search object is equipped with a receiver (FIG. 2) that can identify the predetermined code. The object is displayed by receiving an identification code from the transmitter (Fig. 1). Note that signal transmission methods between the transmitter and receiver include (g) electromagnetic waves, (B) infrared rays, ultrasonic waves (to), and lasers. Further, the input (1) of the transmitter (FIG. 1) is (b) a keyboard (g) from an external combiator system, and the code generation (2) can also be configured with a combiator. The display (6) on the receiver (Figure 2) is 0 Light emitting element (light emitting diode, lamp) (B) Liquid crystal (I) Sound element (speaker, piezoelectric sound element) (J
) Mechanical elements (Icheator), etc. Examples of resets (7) include (6) mechanical switches, touch switches (b), and timer switches.

(e) Example An example of file search using infrared rays as a signal transmission method will be described. (Fig. 3, vJ4) A receiver (Fig. 2) with a light-receiving element a is incorporated in each file. Enter the code of the target file using the keyboard from input (1). Code generation (2), infrared light emitting element 13)
A signal is input to all the light-receiving elements (IG) of the randomly placed file (9) by the transmission (3) marked with. Only the display lamp (6) of the file that matches the input code lights up, making it easy to find the desired file. It can be found.When the file is deleted, press the button (7) and turn off the display lamp (6).

(F) Effects of the Invention As shown in the embodiment (E), the present invention has a very simple configuration and can economically construct a search system.

In addition, there is no need to put files, etc. in a special storage box, and this system can be freely constructed in a place where there are no visitors to send or receive files.

Claims (1)

[Claims] When a large number of items, cases, files, etc. are randomly stored, the item, case, or file has a transmitter (
A receiver (FIG. 2) that can identify the code signal sent from the receiver (FIG. 1) is provided. When a predetermined code is sent from the transmitter, the display (6) of the receiver (Fig. 2) of the target article, case, or file is activated, making it possible to easily find the target object.
