The frame 2 is formed in a rectangular box shape that is short in the Z direction. The frame body 2 has a bottom wall 2a, a top wall 2b, a front wall 2c, a rear wall 2d, a left wall 2e, a right wall 2f, and the like. The bottom wall 2a is also referred to as a lower wall or the like, and the top wall 2b is also referred to as an upper wall or the like. The front wall 2c, the rear wall 2d, the left wall 2e, and the right wall 2f are also referred to as side walls, peripheral walls, and the like.

The bottom wall 2a and the top wall 2b each extend in a direction (XY plane) orthogonal to the Z direction, and are disposed in parallel to each other at intervals in the Z direction. The bottom wall 2a constitutes a lower end portion of the frame body 2, and the top wall 2b constitutes an upper end portion of the frame body 2. Rubber legs or the like may be provided on the bottom wall 2a, and the frame body 2 may be supported by the rubber legs in a state of being separated from an installation surface such as a shelf, a table, or a table.

The left wall 2e and the right wall 2f each extend in a direction (XZ plane) orthogonal to the Y direction, and are arranged in parallel to each other at intervals in the Y direction. The left wall 2e extends between the ends of the bottom wall 2a and the top wall 2b in the Y direction, and the right wall 2f extends between the ends of the bottom wall 2a and the top wall 2b in the opposite direction to the Y direction. The left wall 2e constitutes a left end portion of the frame body 2, and the right wall 2f constitutes a right end portion of the frame body 2.

The front wall 2c and the rear wall 2d each extend in a direction (YZ plane) orthogonal to the X direction, and are arranged in parallel to each other at intervals in the X direction. The front wall 2c extends between the ends of the bottom wall 2a and the top wall 2b in the X direction, and the rear wall 2d extends between the ends of the bottom wall 2a and the top wall 2b in the opposite direction to the X direction. The front wall 2c constitutes the front end of the housing 2, and the rear wall 2d constitutes the rear end of the housing 2.

The front wall 2c is provided with a plurality of slots 3 that open in the X direction. In the present embodiment, two slots 3 are arranged in the Z direction on the left wall 2e side of the center portion in the Y direction and two slots 3 are arranged in the Z direction on the right wall 2f side of the center portion in the Y direction in the front wall 2 c. The

storage units

10 and 20 are detachably mounted in the slot 3.

In the present embodiment, a 3.5-inch HDD (Hard Disk Drive) device 11 is mounted on the storage unit 10, and two 2.5-inch SSD (Solid State Drive) devices 21 are mounted on the storage unit 20. In the present embodiment, the two

storage units

10 and 20 on which the HDD device 11 and the SSD device 21 having different specifications as described above are mounted can be selectively mounted in the same slot 3 and used.

That is, the slot 3 may be shared by the memory unit 10 and the memory unit 20. In the present embodiment, a plurality of

storage units

10 and 20 having different specifications may be mounted in combination in the information processing device 1 by the plurality of slots 3 configured as described above. The HDD device 11 is an example of an auxiliary storage device of the first specification, and the SSD device 21 is an example of an auxiliary storage device of the second specification. The slot 3 is also referred to as a partition, an insertion port, a housing, and the like.

Hereinafter, the

memory cells

10 and 20 and the slot 3 capable of obtaining the above-described effects will be described in more detail. Fig. 2 is an enlarged view of the socket 3. As shown in fig. 2, the slot 3 is composed of a slot holder 31, a guide plate 32, a back plate substrate 33, and the like.

The slot holder 31 is formed in a substantially U shape that opens in a direction opposite to the Z direction when viewed from the X direction. The slot holder 31 covers (partitions) both sides of the Y direction of the slot 3, and covers the Z direction of the slot 3. A pair of projections 37 for positioning to be inserted into the opening 33a of the back plate substrate 33 are provided at the rear end of the slot holder 31.

The guide plate 32 extends in a direction (XY plane) orthogonal to the Z direction and extends between the pair of side walls of the slot holder 31. The guide plate 32 covers the opposite direction of the Z direction of the slot 3, and partitions between two slots 3 aligned in the Z direction. The guide plate 32 is fixed to the slot holder 31 by a fastening member such as a screw or a bolt.

The rear plate substrate 33 extends in a direction (YZ plane) orthogonal to the X direction, and covers the slot 3 in a direction opposite to the X direction.

The connector 34 can be connected to the connector 11a of the HDD device 11 and the connector 21a (see fig. 1) of the SSD device 21. The connector 34 is an example of a connector facing the X direction of the information processing apparatus 1.

Further, a plurality of LEDs 35 are mounted on the front surface of the back substrate 33. The LED35 can display the communication status of the HDD device 11 connected to the connector 34 and the communication status of the SSD device 21. The back plate substrate 33 is integrated with the slot holder 31 by fastening nuts to bolts or the like penetrating the through

holes
