Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a screw mounting mechanism, and more particularly to an information recording apparatus and an information recording / reproducing system for recording information on a disk-shaped recording medium or reproducing information recorded on a recording medium.
[0002]
[Prior art]
Conventionally, there is an information recording / reproducing system for recording information on a disk-shaped recording medium such as a compact disk or reproducing information recorded on the recording medium.
[0003]
In this system, a screw hole is formed on the side surface of the device base into which the recording medium is carried, and the device base and the system side are connected via a screw fitted in the screw hole.
[0004]
In most cases, a control board on which a control element for controlling information for recording information on a recording medium or reproducing information recorded on the recording medium is mounted is mounted on the apparatus base. Also, the control board is often attached in the vicinity of a screw hole on the device base.
[0005]
By the way, since the screw is inserted into the screw hole, a recess is provided so that the tip of the screw does not hit the control board, or the interval between the apparatus base and the control board is adjusted. Further, a slit is often formed around the screw hole of the device base so as to give elasticity to the device base. Furthermore, the base end of the device base is often bent outwardly in the vicinity of the end of the slit.
[0006]
[Problems to be solved by the invention]
However, in the conventional technique, when a screw is fitted into a screw hole formed on the side surface of the device base, stress is applied to the device base around the vicinity of the screw hole. In particular, if a slit is formed or the vicinity of a screw hole is bent like a key, stress concentrates on that part and the vicinity of the screw hole may be bent inward, so the device base and the system cannot be connected well. There was a case.
[0007]
FIG. 4 is an explanatory diagram of problems in the prior art. FIG. 4 shows an apparatus base 2 having a mounting screw part 2a for connecting the main body of the information recording / reproducing apparatus 1 to the system side and a slit 2e for reducing distortion of the mounting screw part 2a when the screw is fitted. The control board 13 is shown.
[0008]
As shown in FIG. 4A, when the distance between the device base 2 and the control board 13 is adjusted so that the tip of the screw does not hit the control board 13 when the screw is inserted into the screw hole, the screw is inserted. 4 (b), the proximal end side of the mounting screw portion 2a is bent toward the control board 13 side.
[0009]
Then, since the apparatus base 2 is inclined with respect to the system main body, the connection between the mounting screw portion formed on the side facing the mounting screw portion 2a and the system side cannot be performed successfully.
[0010]
Therefore, an object of the present invention is to prevent the screw receiving member from being deformed when the screw is inserted into the screw receiving member that is the base of the device in which the screw hole is formed.
[0011]
[Means for Solving the Problems]
In order to solve the above-described problem, the screw mounting mechanism of the present invention includes a screw receiving member in which a screw hole is formed, and the screw is inserted into the screw receiving member on a base material located on a screw insertion destination side. A recess is provided so that the tip of the screw does not hit when the screw is received, and the protruding portion of the recess suppresses the vicinity of the screw hole when the screw is fitted into the screw receiving member.
[0012]
In the information recording apparatus of the present invention, a screw hole is formed on the side surface of the apparatus base into which the recording medium is carried, and the screw is screwed on the board mounted on the apparatus board and in the vicinity of the screw hole. A recess is provided so that the tip of the screw does not hit when it is inserted into the hole, and the protruding portion of the recess suppresses the vicinity of the screw hole when the screw is inserted into the screw hole.
[0013]
Furthermore, the information recording / reproducing system of the present invention comprises an information recording device and a reproducing device for reproducing information recorded on the storage medium.
