  Generally, a disk system including a plurality of disk devices is required to reduce costs and man-hours in the manufacturing process.

  In the above-described video equipment, it is generally required to suppress the thickness of the equipment. However, each of the devices disclosed in Patent Document 1 and Patent Document 2 described above is configured such that the disk devices are stacked and installed in the thickness direction of the disk device. Yes (see FIG. 6).

  Accordingly, the present invention has been made to solve the above-described problems, and it is an object of the present invention to provide a bracket and a disk system that can reduce the thickness of the disk system and reduce costs and man-hours in the manufacturing process. And

  In order to achieve the above object, a bracket according to one aspect of the present invention is a flat bracket that fixes a plurality of disk devices to another member, and each of the plurality of disk devices has a surface with the largest area. And a plurality of first fixing members that fix the bracket to the other member, and a disk installation area for fixing the plurality of disk devices in a straight line, A plurality of first fixing parts for fixing, and a plurality of second fixing parts for fixing a plurality of second fixing members for fixing the plurality of disk devices to the disk installation area.

  The bracket of this configuration is a flat-plate bracket and includes a disk installation area for fixing a plurality of disk devices. Therefore, a single bracket may be prepared for a plurality of disk devices. That is, one bracket is shared by a plurality of disk devices.

  When a dedicated bracket is provided for each of a plurality of disk devices as in the storage device of Patent Document 2, it is necessary to manufacture as many brackets as the number of disk devices, but the bracket of this configuration is a single bracket. Therefore, it is possible to reduce the number of man-hours in the manufacturing process in the entire disk system. Further, it is considered that the amount of the material constituting the bracket can be reduced with the common use of the bracket of this configuration.

  Further, the bracket of this configuration is configured so that each of the disk devices is installed so that a part or all of the surface having the largest area is in contact with each other and arranged in a straight line. Compared to the case of stacking, the thickness of the disk system housing can be reduced.

  In addition, the plurality of first fixing portions are arranged at at least three locations around the disk device arranged at the end of the plurality of disk devices, and at least one of the two adjacent disk devices. It may be arranged at a place.

  With this configuration, the disk device can be stably fixed. Furthermore, the bracket having the above-described configuration can reduce the number of first fixing portions (for example, holes for fixing screws) and first fixing members (for example, screws). This makes it possible to reduce manufacturing costs and manufacturing processes.

  Furthermore, among the plurality of first fixing portions, the plurality of first fixing portions arranged around the disk device arranged at the end includes a disk device arranged at the end and a disk adjacent to the disk device. It may be arranged at two locations between the devices and at one location opposite to the adjacent disk device.

  For example, when a dedicated bracket is provided for each disk device, four first fixing portions and first fixing members are required for each disk device, and 4 × n (n is the number of disk devices) for three disk devices. The first fixing part and the first fixing member are required. On the other hand, in the bracket configured as described above, the number of the first fixing portions and the first fixing members is (the number of first fixing portions arranged around the disk device at the end portion) + (the disk device other than the end portion). The number of the first fixed parts arranged around the area) − (the number of the first fixed parts shared) = 3 × 2 + 4x (n−2) −2x (n−1) = 2xn. That is, the number of the first fixing portions and the first fixing members in this configuration is half the number of the first fixing portions and the first fixing members in the case where a dedicated bracket is provided in each disk device. This makes it possible to reduce manufacturing costs and manufacturing processes.

  The bracket further includes a plurality of third fixing portions for fixing a plurality of third fixing members that are different from the first fixing member and fix the bracket to the housing. It may be.

  For example, as a method of fixing the bracket to the housing, for example, a method of fixing by a screw, a method of fixing by a screw or the like can be considered. By providing a fixing portion (for example, the first fixing portion or the third fixing portion) corresponding to each aspect (type) of the fixing method, a plurality of fixing methods can be selected with one bracket. The range of use can be expanded.

  Of the plurality of third fixing portions, the plurality of third fixing portions arranged around the disk device arranged at the end includes a disk device arranged at the end and a disk adjacent to the disk device. It may be arranged at one place between the devices and at two places on the opposite side to the adjacent disk device.

  If the third fixing portion is arranged in this manner, the distance from the other fixing portions including the first fixing portion can be appropriately maintained. Thereby, the disk device can be stably fixed.

  In order to achieve the above object, a disk system according to an aspect of the present invention includes a plurality of disk devices, a housing, a flat bracket that fixes the plurality of disk devices to the housing, and the bracket. A plurality of first fixing members for fixing to the housing; and a circuit board having a circuit that communicates with the plurality of disk devices, wherein the bracket has a maximum area for each of the plurality of disk devices. A disk installation area for fixing the plurality of disk devices in a straight line with a part or all of the surfaces in contact with each other, and a plurality of first fixings for fixing the plurality of first fixing members And a plurality of second fixing members for fixing a plurality of second fixing members that fix the plurality of disk devices to the disk installation area.

  By providing the above-described bracket, the disk system can achieve the effects of the above-described bracket.

  Furthermore, workability in the manufacturing process can be improved by using the bracket described above. For example, the work of fixing the bracket to the casing is performed in a casing having a relatively small space. When there are a plurality of brackets, it is necessary to perform such work a plurality of times depending on the number of brackets. On the other hand, if the bracket is used in common, the amount of work for fixing the bracket to the housing can be reduced, for example, the bracket can be positioned once, and workability can be improved. Thereby, the work amount in the manufacturing process can be reduced, and the manufacturing cost can be reduced.

  Further, the substrate is a single board for electrically connecting the plurality of disk devices and the circuit board, and a first connection portion for connecting to each of the plurality of disk devices installed on the bracket; The assembly board may include a second connection part for connecting to the connection part of the circuit board, and a wiring part including a wiring connecting the first connection part and the second connection part.

  Generally, in a disk system in which a plurality of disk devices are mounted, when each disk device and a substrate are connected by a signal cable, the signal cable needs to be disconnected from a power supply circuit. For this reason, conventionally, a method of providing a shield member for shielding the power supply circuit or widening the space between the signal cable and the power supply circuit has been adopted. When the shield member is provided, the manufacturing cost increases, and when the space is widened, there is a problem that the size of the housing of the disk system may be increased.

  On the other hand, in the disk system, a plurality of disk devices and a circuit board are connected via a collective board. As a result, the interfaces (with circuit boards) of the plurality of disk devices can be integrated into the second connection portion of the collective board without using a signal cable. By consolidating the interfaces of the plurality of disk devices into the second connection portion of the collective board, it becomes possible to reduce the space required for connection to the circuit board, for example, the installation space for connectors and signal cables. Thereby, the size of the housing of the disk system can be reduced.

  Further, the second connection portion of the collective substrate and the connection portion with the collective substrate provided on the circuit board may be detachable connectors.

  If the assembly board and the circuit board are connected by a detachable connector, the disk device and the circuit board can be connected without a signal cable. As a result, the installation space for the signal cable can be reduced, and the size of the housing of the disk system can be reduced.

  Further, the second connection part of the collective substrate may be a movable connector.

  If the movable board is configured to connect the collective board and the circuit board, for example, even when a vibration occurs in the disk system, the collective board and the circuit board are effectively unintentionally disconnected. It becomes possible to prevent.

  In the bracket and the disk system using the bracket, it is possible to achieve cost reduction and man-hour reduction in the manufacturing process.
