[0007]

By the way, a plurality of models of this type of external storage device are designed and manufactured, and the internal structure is different for each model. However, in the conventional ejection mechanism 57, since the geared motor 42 is also incorporated in the main body 1a of the external storage device 1, the fixed position and the mounting method of the geared motor 42 are different for each model, and the ejection operation The shape of the driven member 69 of the member 61 and the positional relationship between the driven member 69 and the driving member 10 of the geared motor 42 are different. Therefore, it is necessary to design the geared motor 42 for each model, which reduces the productivity of the eject mechanism 57. In recent years, the external storage device 1 of this type has also been reduced in size, and the space for disposing the geared motor 42 in the main body 1a has become narrower. The assembly work for mounting is difficult. Further, when the eject operation member 61 is manually operated, the geared motor 42 is not disposed in the main body 1a, but the space for disposing the geared motor 42 in the main body 1a remains as a useless space, Unnecessary space is occupied by the eject mechanism 57.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the productivity can be improved by applying a geared motor having the same shape to a plurality of types of external storage devices.
An object of the present invention is to provide an ejection mechanism for an external storage device that is easy to assemble without occupying unnecessary space even when the ejection operation is manually performed and a geared motor is not provided.

[0009]

An ejection mechanism for an external storage device according to the present invention mounts a geared motor on an outer surface of an external storage device main body, and further includes a drive member provided on an output shaft of the geared motor, and an ejection operation member. The driven member is connected to the external storage device main body or the geared motor by a connecting lever rotatably supported at one end thereof.

[0010]

According to the above structure, by changing the connecting lever without changing the shape of the geared motor, the geared motor having the same shape can be applied to a plurality of types of external storage devices. This eliminates the need for designing a geared motor, thereby improving productivity. Also,
There is no need to mount the geared motor in a narrow installation space, and the work of assembling the eject mechanism becomes easier. Further, since there is no need to provide a space for arranging the geared motor in the external storage device main body, even when the geared motor is manually operated and the geared motor is not arranged, unnecessary space is not occupied by the eject mechanism. .

[0011]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a main part of an example of an ejection mechanism of an external storage device according to the present invention, which is partially cut away.
The same parts as those in the related art are denoted by the same reference numerals, and detailed description thereof will be omitted. 3A is different from FIG. 3A in that the geared motor 42 is mounted on the outer surface of the main body 1a of the external storage device 1 and the driven member 10 of the geared motor 42 and the driven member of the ejection operation member 61. 69 with the connecting lever 3. One end of the connecting lever 3 is rotatably supported by a geared motor 42 by a pin 4, and an eccentric pin 23 of the driving member 10 is attached to an engaged portion 3 a formed at the other end.
And the drive pin 3c formed on the operation piece 3b of the connection lever 3 protruding into the main body 1a of the external storage device 1 is engaged with the driven member 69 of the eject operation member 61. .

As shown in FIG. 2, when the holder 59 is at the lowered position, the driving pin 3c and the driven member 69
Is at a position shown by a broken line, and the connecting lever 3 is at a position shown by a solid line. When the geared motor 42 is driven, the drive member 10 fixed to the output shaft 27 is rotated, and the connecting lever 3 is displaced by the eccentric pin 23 to a position shown by a chain line. Due to this displacement, the driven member 69 is displaced to the position indicated by the dashed line via the drive pin 3c of the connecting lever 3, and the ejecting operation is performed in the same manner as the conventional one.

As described above, since the geared motor 42 is mounted on the outer surface of the main body 1a of the external storage device 1 and connected to the ejecting operation member 61 by the connecting lever 3, the same shape of the geared motor 42 is stored in the external storage device having a different internal structure. Apparatus 1
Can be mounted on a plurality of models, and the geared motor 42 can be easily mounted without being mounted in a narrow installation space. Further, for example, even if the driven member 69 of the ejecting operation member 61 has a different shape, the geared motor 42 having the same shape can be handled by changing the shape of the connecting lever 3. There is no need to design, and the productivity of the eject mechanism 57 is improved. Further, the external storage device 1
Since there is no space for disposing the geared motor 42 in the main body 1a, the eject mechanism 57 does not occupy an unnecessary space even if the geared motor 42 is not disposed by manually performing the eject operation. In the above embodiment, the case where the connection lever 3 is supported by the geared motor 42 has been described, but it goes without saying that the connection lever 3 may be supported by the main body 1a of the external storage device 1.

[0014]

As described above, according to the present invention, productivity can be improved by applying a geared motor having the same shape to a plurality of types of external storage devices, and the geared motor is manually operated by ejecting. Even when not performed, an unnecessary space is not occupied, and an ejecting mechanism of the external storage device which is easy to assemble can be provided.
