Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a module attaching / detaching structure attached to an electronic device such as a deskside computer.
[0002]
[Prior art]
An example of such a conventional module device is shown in FIG. (A) is a top view, (B) is a front view, and (C1) and (C2) are a right side view and a left side view, respectively. In the figure, a side plate 2 is fixed to the left and right side surfaces of the module device 1, and the side plate 2 and the module device 1 are fixed by a fixing bracket 3.
[0003]
A groove 4 is formed between the module device 1 and the side plate 2, and one end of the handle 5 is inserted into the groove 4.
[0004]
With such a configuration, when the module device 1 is detached from the main body, the handle 5 is pulled out by applying force.
[0005]
On the other hand, when the module device 1 is attached to an electronic device main body (not shown), it is necessary to fix the module device 1 with a screw or the like via the fixing bracket 3. Since the module device 1 is not provided with a power line on / off switch while the electronic device main body is in operation, the electronic device main body is stopped when the module device 1 is attached or detached. Therefore, the procedure of pulling out the module device 1 from the main body had to be taken.
[0006]
[Problems to be solved by the invention]
In such a conventional module device 1, when removing the module device 1 from the electronic device main body, the handle 5 (FIG. 5) is pulled out with force, so that when the module device 1 is pulled out, a strong impact is applied to the module device 1. As a result, there has been a problem in that electronic components built into the module device 1 are damaged or wiring damage is caused.
[0007]
On the other hand, when the module device 1 is attached to the electronic device main body, the fixing bracket 3 (FIG. 5) must be fixed with a screw or the like, and the screw may be dropped into the electronic device main body during the assembly work. The assembly time increased significantly, which was a major factor preventing cost reduction.
[0008]
Furthermore, since it is necessary to stop the operation of the electronic device body when the module device 1 is attached / detached, the attachment / detachment work efficiency deteriorates, and in addition, the removal of the connector also reduces the durability of the power cable itself. There was a problem of letting.
[0009]
Therefore, the object of the present invention is to attach and detach the module device from the electronic device main body without giving an extra impact to the module device, and to eliminate the extra detachment operation to shorten the detachment time. An object of the present invention is to provide an electronic device ejecting apparatus that does not impair the durability of the connector.
[0010]
