Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application 1 The present invention relates to an electronic device formed by a plurality of electronic circuit packages, such as an electronic computer or an electronic exchange.

[Prior Art] An example of a conventional implementation of this type of electronic device is shown in FIG.
40, 41 in FIG. ,．． 4n is an electronic circuit package, and these multiple electronic circuit packages are housed in a housing 4.
00, and the device was constructed by connecting electronic circuit packages using a wiring board or wiring on the front or back surface of the housing 400, or both.

[Problems to be Solved by the Invention] In the electronic device described above, the electronic circuit package is usually composed of a printed board with the same structure, and these multiple electronic circuit packages, each having a different function, have a different appearance. , may look the same. Each electronic circuit package functions as a device only when it is mounted in its designated location, but for the reasons mentioned above, it may be mounted in the wrong location, and in such cases, the parts that make up the circuit There were drawbacks such as damage to printed circuit boards.

[Means for Solving the Problems] The present invention has been made by focusing on the above-mentioned conventional problems, and it solves five problems by easily detecting incorrect mounting of an electronic circuit package mounted on an electronic device. It is an object of the present invention to provide an electronic device that can prevent damage to circuits due to incorrect mounting.

To this end, the present invention provides, in an electronic device constituted by a plurality of electronic circuit packages, displaying the product name of the electronic circuit package and individual identification symbols, characters, etc. on the printed board forming each electronic circuit package. A recognition circuit that irradiates light from a direction facing this and recognizes the displayed information, a circuit that compares the identified information with the stored insertion order and display information, and a circuit that displays or alarms the comparison result at least. The present invention provides an electronic device characterized by having the following features.

[Example] Next, an example of the present invention will be specifically described with reference to the drawings.

FIG. 1(a) shows an electronic circuit package 210 with a display according to an embodiment of the present invention. ,．． 21n, in which (b), (c), and (d) each show an example of displayed information, (b) is an alphabetic character 400, (C) is a number and symbol 401. (d) shows the case where the barcode 402 is displayed, and both are displayed in the area X indicated by the dashed dotted line in FIG.

Figure 2 shows a housing 200 containing multiple packages shown in Figure 1.
It is a model diagram of a device implemented in

210 to 21n are electronic circuit packages; 210.
21i, . . . , 21n are implemented from the left in this order. 220 is a recognition response alarm circuit. Figure 3 shows a recognition response alarm circuit, 31 is a power supply, 32 is an external load circuit, 3
3 is a light irradiation circuit.

34 is a recognition circuit, 35 is a memory/comparison circuit, and 36 is a display/alarm circuit. The storage/comparison circuit 35 stores information to be displayed in the order of the electronic circuit packages to be mounted.The electronic circuit packages are inserted in order from the left side of the housing 200, and the display section of the electronic circuit package receives the irradiated light. Recognize the display contents as you pass by. When the packages are sequentially inserted and the information recognized each time does not match the order stored in the storage/comparison circuit 35 or the displayed information, the 1 display/alarm circuit 36 is activated.

[Effects of the Invention] As explained above, the present invention provides an electronic device including a plurality of electronic circuit packages, in which a printed circuit board forming each electronic circuit package is provided with the product name of the electronic circuit package and an individual identification symbol. , a recognition circuit that displays characters, etc., irradiates light from the direction facing the display, and recognizes the displayed information; a circuit that compares the identified information with the stored insertion order and display information; and a display of the comparison results. Since the electronic device is characterized by having at least one of the following circuits and an alarm circuit, it is possible to easily detect incorrect mounting of an electronic circuit package mounted on the electronic device, thereby preventing damage to the circuit due to incorrect mounting. You can get the effect of being able to do things.

[Brief explanation of drawings]

FIG. 1(a) is a general view of a puff cage with a display according to the present invention, and FIGS. 1(b) to (d) are explanatory diagrams showing examples of displayed information. FIG. 2 is a schematic perspective view of an electronic device according to an embodiment of the present invention. FIG. 3 is a conceptual diagram of a recognition response alarm circuit, and FIG. 4 is a perspective view showing a conventional example. 210 to 21n: Electronic circuit package 220: Recognition response alarm circuit 200: Housing 33: Light irradiation circuit 34: Recognition circuit 35: Memory/comparison circuit 36: Display/alarm circuit

Claims (1)

[Claims] In an electronic device composed of multiple electronic circuit packages, the product name of the electronic circuit package and individual identification symbols, characters, etc. are displayed on the printed circuit board forming each electronic circuit package, and the printed circuit board forming each electronic circuit package is displayed with light from the direction facing it. The device is characterized by having a recognition circuit that recognizes the displayed information, a circuit that compares the identified information with the stored insertion order and display information, and a circuit that displays or warns the comparison result. electronic equipment.
