Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a memory cassette that is detachably attached to an electronic device.

[Prior Art] Conventionally, in electronic devices such as personal computers, a removable memory cassette is inserted into the main body of the electronic device to connect electrical connections within the main body of the electronic device. It is designed to electrically connect the electrode terminals of the memory cassette. The connection method is, for example, by inserting the memory cassette into the main body of the electronic device and sliding the electrode terminal provided on the board of the memory cassette into electrical connection part within the main body of the electronic device. Alternatively, the electrical connection part in the main body of the electronic device is formed into a concave shape, and the electrode terminal provided on the board in the memory cassette is inserted into the concave electrical connection part to connect it. and,
In addition, it has been considered to connect the electrode terminals exposed on the surface of the external case of the memory cassette to the electrical connections provided on the electronic device by pressing the memory cassette against the electronic device. Regardless of the connection method, the electrode terminals of the memory cassette are exposed from the surface of the external case.

[Problem to be solved by the invention] However, when the electrode terminals are led out from the memory cassette and exposed as described above, static electricity easily enters through the electrode terminals, and the electronic components installed inside the memory cassette are damaged. It was dangerous.

This is because static electricity infiltrates the electronic components from the exposed electrode terminals.

In view of this, it seems that the structure of the electrode terminal should be such that it is possible to suppress the intrusion of static electricity from the electrode terminal.

Therefore, if a lid that can be opened and closed is provided to prevent static electricity from entering, if you forget to open the lid when inserting a memory cassette and then specify data collection, data will not be collected and you will have to try again. If the memory contents are cleared by collection or collection, there will be an inconvenience that the data will be lost.

The object of this invention is to cover the electrode terminals of a memory cassette with an opening/closing lid so that the opening/closing lid can be opened when the cassette is installed into the main body of an electronic device.

[Means to solve the problem] The means of this invention are as follows.

(1) External case 19 containing electronic components.

For example, on a circuit board installed with screws.
It has built-in electronic components such as ICs.

(2) Electrode terminal 24 derived from the electronic component.

For example, it is a terminal derived from an electronic component and provided on a circuit board.

(3) An opening formed in the outer case 19 to expose the electrode terminal 24.

For example, one is provided on an external case facing an electrode terminal on a circuit board.

(4) An opening/closing lid 22 that covers the opening so that it can be opened and closed.

For example, the opening is opened or closed by sliding or the like.

(5) An engaging portion 28 provided on the opening/closing lid 22.

For example, it is a protrusion provided on an opening/closing lid that comes into contact with a locking member in the main body of the electronic device and slides the opening/closing lid to open the opening/closing lid when the electronic device is stored in the main body.

[Effect] The function of this device is as follows.

When a memory cassette is inserted into the main body of an electronic device in order to connect the electrical connection part provided inside the main body of the electronic device and the electrode terminal derived from the electronic component built in the external case, The engaging part of the opening/closing lid, which is provided corresponding to the electrode terminal and covering the opening of the memory cassette, comes into contact with the engaging member provided inside the main body of the electronic device, and the opening/closing lid slides to open. Then, the electrical connection part and the electrode terminal are connected, and the memory cassette is installed.

Therefore, the electrode terminals of the memory cassette can be covered with the opening/closing lid, and the opening/closing lid can be opened when the memory cassette is installed into the main body of the electronic device.
