Abstract

PROBLEM TO BE SOLVED: To prevent the falling of a recording medium from a substrate by providing a mechanism for engaging a leaf spring provided in the substrate with a notch provided in the recording medium to be detached when the recording medium to be detached falls from a connector connected to a printed circuit board. SOLUTION: The substrate connecting terminal 1b of a connecting pin 1a is electrically connected to a printed circuit board 4 by solder, and a connector 1 is connected to the connecting pin 1a. For example, the electric contact of a compact flash 2 is engaged with the connecting pin 1a, and the compact flash 2 is fixed in the connector 1. The compact flash 2 and the connector 1 are disconnected by an eject button or the like, and when the compact flash 2 and the connector are separated, the catch part 3a of a leaf spring 3 fixed in the printed circuit board 4 enters to be engaged with a notch 2b provided in the compact flash 2, and thereby the falling of the compact flash 2 from the device is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for attaching and detaching a recording medium used in an electronic still camera, information equipment, and the like.
In particular, it relates to a mechanism for preventing a detachable recording medium from falling off.

[0002]

2. Description of the Related Art Conventionally, when a user carries a camera by using a hand strap and holds the camera with his / her hand, the removable recording medium is ejected even when the removable recording medium insertion opening faces downward. There has been proposed a structure in which a detachable recording medium does not fall out of a slot due to its own weight and is dropped because the recording medium is locked by a part thereof (for example, Japanese Patent Application Laid-Open No. 5-145881).

[0003]

However, in the prior art, when the eject button or the like is operated to eject the recording medium, the connector having electrical contacts and the detachable recording medium are detached. It is an unstable state until the detached recording medium is grasped by hand and removed.
A removable recording medium may fall out of the slot and fall due to the posture of the apparatus. In addition, there is a problem that the spring pressure varies depending on the position where the leaf spring for preventing falling off is attached, or that the assembling workability is poor.

An object of the present invention is to prevent a recording medium from being dropped by mistake when the recording medium is replaced by disconnecting a connector from the recording medium by an eject button or the like from a recording / reproducing apparatus. Is to provide.

[0005]

According to the present invention, there is provided a recording / reproducing apparatus provided with a connector to which a detachable recording medium is electrically connected, wherein the detachable recording medium is provided with the connector. A recording medium drop-off preventing means for preventing the recording medium from dropping off from the recording / reproducing apparatus in a state where the recording medium is detached from the recording / reproducing apparatus; Provided is a recording medium falling prevention mechanism, which is provided with a leaf spring-like member provided on a medium and a notch portion which is engaged and disengaged.

Further, in the above invention, there is provided a recording medium falling prevention mechanism, wherein the fixing portion of the recording / reproducing device is the same printed circuit board on which the connector is provided or the connector.

[0007] According to the above configuration, even when the attitude of the recording / reproducing apparatus is changed while the detachable recording medium is detached from the connector having the electrical contact, the recording medium does not drop out of the recording / reproducing apparatus by its own weight. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a compact flash which is a recording medium also used in the present invention, and FIG. 2 is a schematic cross-sectional view of the embodiment of the recording medium drop-preventing mechanism of the present invention viewed from the side. FIG. 3 is a schematic cross-sectional view showing a state where the compact flash is connected to the connector, and FIG. 4 is a schematic cross-sectional view of another embodiment of the recording medium drop prevention mechanism according to the present invention, seen from the side. FIG. 4 is a diagram showing a state where a flash is connected to a connector. In the figures, the same parts are denoted by the same reference numerals, 1 is a connector for compact flash, 1a is a connection pin, 1b is a board connection terminal, 2 is a compact flash, 2a is a groove for erroneous insertion determination, 2b is a cutout, and 2c is Electric contact, 3 is leaf spring, 3
Reference numeral a denotes a nail portion, and reference numeral 4 denotes a printed circuit board. Next, the operation in such a configuration will be described. FIG. 1 shows the appearance of a compact flash, which is a recording medium, with grooves 2 on both sides of the compact flash 2 for distinguishing front and back.
a and an electric contact 2c electrically connected to the notch 2b on the back side.

FIG. 2 shows a state in which the compact flash according to the first aspect of the present invention is detached from the connector. The printed board 4 and the compact flash connector 1 are formed by soldering the board connection terminals 1b to the printed board 4. The electrical connection is established, the connection pin 1a and the electrical contact 2c of the compact flash 2 are disengaged by the eject mechanism, and the compact flash 2 and the connector 1 are detached. At this time, the claw 3a of the leaf spring 3 fixed to the printed circuit board 4 enters the notch 2b of the compact flash 2, and the compact flash 2 does not fall out of the device even if the posture of the device is changed. Here, when the compact flash 2 is picked out with a finger, the claw portion 3a of the leaf spring 3 that has entered the notch 2b of the compact flash 2 is pushed toward the printed circuit board 4 and flexes, so that the compact flash 2 can be pulled out. .

FIG. 3 shows a state in which the compact flash is attached to the connector. The claw 3a of the leaf spring 3 which has been inserted into the notch 2b of the compact flash 2 is pushed by the compact flash 2 and flexed toward the printed circuit board 4 side. The electric contacts 2c of the flash 2 are engaged with the connection pins 1a of the compact flash connector 1 and are electrically connected.

In the present invention, a general-purpose compact flash connector can be used, and the leaf spring 3 can be arranged on the same printed circuit board 4 as the compact flash connector 1. Therefore, the claw portion 3a of the leaf spring 3 and the notch of the compact flash 2 are cut off. The position accuracy of 2b can be increased. FIG.
Is another embodiment of the recording medium falling-off prevention mechanism of the present invention, and shows a state where the compact flash and the connector are connected. In the figure, the leaf spring 3 is provided on the bottom surface of the compact flash connector 1 and is arranged so that the claw portion 3a of the leaf spring 3 enters the notch 2b of the compact flash 2. In the embodiment of the present invention, the leaf spring 3 has an integral structure with the connector 1 for the compact flash, so that the assembling workability is improved.

[0012]

As described above, according to the structure of the present invention, it is possible to prevent the recording medium from being erroneously dropped when the recording medium is detached. When a general-purpose connector is used, assembling accuracy can be ensured by arranging the connector on the same printed circuit board, and assembling workability is improved by arranging a leaf spring on the connector.
