The present invention relates to a portable digital device, and more particularly, to a portable digital device capable of accommodating the terminal portion into the inside of the main case or withdrawing the outside of the main case.

In response to the rapidly changing network environment and the demand for more convenient data storage and mobility, various portable storage media have emerged one after another, and in response to the demand of the new storage media, high-capacity storage devices using flash memory are provided. Portable digital devices are emerging.

The biggest feature of these portable digital devices is that they can be easily connected without the need for a separate adapter, no need for a separate power supply, and excellent portability and mobility.

On the other hand, such a portable digital device is designed and used as a structure that requires a cover in terms of protecting the user due to the sharpness of the material and the sharpness of the material to the USB terminal.

If you want to use a portable digital device, apply the exposed USB terminal to the computer's USB port while applying force to the cover surrounding the USB terminal and insert the USB terminal into the cover when finished. Store in one condition. At this time, since the user does not have a method of separately storing the separated cover, the portable digital device having the existing detachable cover may lose the cover even in normal use. In addition, since the front end and the coupling part is loose and the cover is spontaneously separated from the main body and is frequently lost, in this case, there is a problem in that the USB terminal, which is a key component of the portable digital device, is damaged and the portable digital device cannot be used.

In order to solve this problem, the portable digital device according to the prior art allows the terminal unit to be housed inside the main case forming the outer shape, and the user can draw out the terminal unit by the button formed on the upper or rear surface of the main case only when using the user. To make it more convenient to carry and store.

However, there are the following problems in the portable digital apparatus according to the prior art as described above.

In the related art, since a button for inserting or withdrawing a terminal unit is formed on the upper or lower surface of the main case, the thickness of the portable digital device becomes thick and the portability is poor.

The present invention is to solve the problems of the prior art as described above, the object of the present invention is to provide a portable digital device having a more slim appearance.

According to a feature of the present invention for achieving the object as described above, the present invention includes a main case formed on the side spaced apart from the first fixing hole and the second fixing hole by a predetermined distance; A main body unit which is installed in and out of the main case; It is installed on the main body, the button is moved together with the main body, the button is selectively inserted into the first fixing hole or the second fixing hole, the rear end is provided with a spring to provide an elastic force in the direction in which the main body is drawn out It is configured to include a fastener provided.

It is mounted to the main case to guide the movement of the main body portion, and further comprises a guide frame for supporting one end of the spring.

The other side of the guide frame 40 is formed with a plurality of fastening portion 46 for fixing the guide frame 40 to the main case.

Hereinafter will be described in detail the operation of the portable digital device according to the present invention having the configuration as described above.

3 is a plan view showing a state in which the terminal portion is inserted into the inside of the main case in the embodiment of the present invention, Figure 4 is a plan view showing a state in which the terminal portion is drawn out of the main case in the embodiment of the present invention. It is.

First, when the coupling state of the portable digital device according to the present invention, the main body 10 is seated on the fastener 20, the projection insertion hole 12 in the main body fixing projections 30 By inserting the body portion 10 is fixed to the fastener 20.

The fastener 20 to which the main body 10 is fixed is inserted into the guide frame 40. The spring S is positioned between the first spring fixing protrusion 30 and the second spring fixing protrusion 42. One end of the spring (S) is inserted into the first spring fixing protrusion 30, the other end is inserted into the second spring fixing protrusion 42. The spring S is supported by the second spring fixing protrusion 42 to provide an elastic force in the extraction direction of the body portion 10.

The terminal portion 14 provided in the main body portion 10 performs a linear reciprocating motion inside the guide frame 40. The terminal portion 14 is drawn out of the main case 10 through the connecting jack hole (2). At this time, the button 34 provided in the fastener 20 performs a linear reciprocating motion in the guide groove 44 formed in the guide frame 40.

As such, the guide frame 40 having the main body 10 and the fastener 20 is installed in the main case 1 as bolts are fastened to the fastening portion 46.

Before the terminal 14 is drawn out from the portable digital device, as shown in FIG. 3, the button 34 is located in the first fixing hole 4 in the state in which the spring S is compressed. The hook hook 36 is located in the first hook fixing groove 7.

When the button 34 is pressed by an external force, the button 34 moves in a direction perpendicular to the second support part 24 while elastically deforming the second support part 24, and the hook hook 36 Is released from the first hook fixing groove (7). When the first inclined surface 34 'of the button 34 reaches the first interlocking inclined surface 4', the main body 10 is moved outside of the main case 1 by the elastic force of the spring S. Withdrawn.

In addition, the fastener 20 moves toward the connection jack hole 2 of the main case 1 together with the terminal portion 14. As shown in FIG. 4, when the terminal portion 14 is completely drawn out of the connection jack hole 2, the button 34 is positioned at the second fixing hole 5, and the hook hook 36 is inserted into and fixed to the second hook fixing groove 8.

When the terminal portion 14 is inserted into the portable digital device, the button 34 is pressed by an external force, and the button 34 moves into the main case 1. At this time, the hook hook 36 is released from the second hook fixing groove (8). When the second inclined surface 35 'of the button 34 reaches the second interlocking slope 5', the fastener 20 is connected to the second inclined surface 35 'and the second interlocking slope 5'. Guided and moved.

At this time, the terminal 14 seated on the fastener 20 overcomes the elastic force of the spring S and moves to the inside of the main case 1. When the terminal portion 14 is fully inserted into the connection jack hole 2, the button 34 is positioned in the first fixing hole 4, and the hook hook 36 is fixed to the first hook. It is inserted into the groove 7 and fixed.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.

As described in detail above, according to the portable digital device according to the present invention, the following effects can be expected.

According to the present invention, since a button for accommodating or withdrawing the terminal unit into the main case is formed on the side of the main case, the thickness of the portable digital device is reduced, thereby making the appearance slimmer and improving portability.
