Abstract

An information processing apparatus includes a lower unit having a circuit board on which first electronic components are mounted and also having a chassis in which the circuit board is mounted at a bottom, an upper surface of the chassis being open; and an upper unit having a tray member detachably attached to the chassis and also having second electronic components mounted at a bottom of the tray member, the upper unit being stacked on the lower unit; wherein the upper unit has a connector board attached to the tray member, having a first and a second connectors, the first connector being fitted to a board-side connector on the circuit board, the second connector being electrically connected to the second electronic components, and an opening is formed at the bottom of the tray member, the first connector and the board-side connector being mutually fitted through the opening.

First claim

What is claimed is:

1. An information processing apparatus comprising:
a lower unit that has a circuit board on which one or a plurality of first electronic components are mounted and also has a chassis in which the circuit board is mounted at a bottom, an upper surface of the chassis being open; and
an upper unit that has a tray member detachably attached to the chassis and also has one or a plurality of second electronic components mounted at a bottom of the tray member, the upper unit being stacked on the lower unit; wherein
the upper unit has a connector board attached to the tray member, the connector board having a first connector and a second connector, the first connector being fitted to a board-side connector provided on the circuit board, the second connector being electrically connected to the second electronic components, and
an opening is formed at the bottom of the tray member, the first connector and the board-side connector being mutually fitted through the opening,
wherein the apparatus further comprises:
a connector board holding part that holds the connector board, the connector board holding part being detachably attached to a side surface of the tray member; and
a guide mechanism that guides the connector board holding part attached to the tray member and selectively fits and detaches the first connector to and from the board-side connector,
wherein the guide mechanism includes a guide pin formed on a side surface of the upper unit and also includes an alignment slit formed in the connector board holding part, the alignment slit accepting the guide pin so as to be removable and slidable.

2. The information processing apparatus according to claim 1 , wherein:
the alignment slit includes a first slit extending in a direction in which the first connector is fitted to the board-side connector and also includes a second slit extending from the first slit part in a direction in which a misalignment occurs between a planar position of the board-side connector and a planar position of the first connector; and
the planar position of the board-side connector and the planar position of the first connector are aligned with each other in a state in which the guide pin is positioned in the first slit.

3. The information processing apparatus according to claim 1 , wherein:
a flange is provided so as to protrude from the erected wall erected from the bottom of the chassis toward an inside of the chassis, a first through-hole being formed in the flange;
a second through-hole is formed in the bottom of the tray member, the second through-hole coinciding with the first through-hole in a state in which the engaging pin is positioned at an end of the horizontal slit;
the connector board holding part has a lock piece that is insertable into the first through-hole and the second through-hole; and
the lock piece is inserted into both the first through-hole and the second through-hole when the first connector is fitted to the board-side connector, and is pulled out from the first through-hole and the second through-hole when the first connector is detached from the board-side connector.

4. The information processing apparatus according to claim 1 , further comprising a lock mechanism that suppresses a relative misalignment between the lower unit and the upper unit in a planar direction of the lower unit and the upper unit in a state in which the first connector is fitted to the board-side connector.

5. An information processing apparatus comprising:
a lower unit that has a circuit board on which one or a plurality of first electronic components are mounted and also has a chassis in which the circuit board is mounted at a bottom, an upper surface of the chassis being open; and
an upper unit that has a tray member detachably attached to the chassis and also has one or a plurality of second electronic components mounted at a bottom of the tray member, the upper unit being stacked on the lower unit; wherein
the upper unit has a connector board attached to the tray member, the connector board having a first connector and a second connector, the first connector being fitted to a board-side connector provided on the circuit board, the second connector being electrically connected to the second electronic components,
an opening is formed at the bottom of the tray member, the first connector and the board-side connector being mutually fitted through the opening,
an attachment and detachment slit is formed in an erected wall erected from the bottom of the chassis, the tray member being attached to and detached from the chassis by inserting and removing an engaging pin into and from the attachment and detachment slit, the engaging pin protruding from an external surface of a tray side wall erected from the bottom of the tray member, and
the attachment and detachment slit includes a vertical slit extending downward from an upper edge of the erected wall of the chassis toward the bottom of the chassis and also includes a horizontal slit part extending from a lower end of the vertical slit in a direction along the circuit board.

6. The information processing apparatus according to claim 5 , further comprising:
a connector board holding part that holds the connector board, the connector board holding part being detachably attached to a side surface of the tray member; and
a guide mechanism that guides the connector board holding part attached to the tray member and selectively fits and detaches the first connector to and from the board-side connector.

7. The information processing apparatus according to claim 6 , wherein the guide mechanism includes a guide pin formed on a side surface of the upper unit and also includes an alignment slit formed in the connector board holding part, the alignment slit accepting the guide pin so as to be removable and relatively slidable.

8. The information processing apparatus according to claim 7 , wherein:
the alignment slit includes a first slit extending in a direction in which the first connector is fitted to the board-side connector and also includes a second slit extending from the first slit part in a direction in which a misalignment occurs between a planar position of the board-side connector and a planar position of the first connector; and
the planar position of the board-side connector and the planar position of the first connector are aligned with each other in a state in which the guide pin is positioned in the first slit.

9. The information processing apparatus according to claim 5 , wherein:
a flange is provided so as to protrude from the erected wall erected from the bottom of the chassis toward an inside of the chassis, a first through-hole being formed in the flange;
a second through-hole is formed in the bottom of the tray member, the second through-hole coinciding with the first through-hole in a state in which the engaging pin is positioned at an end of the horizontal slit;
the connector board holding part has a lock piece that is insertable into the first through-hole and the second through-hole; and
the lock piece is inserted into both the first through-hole and the second through-hole when the first connector is fitted to the board-side connector, and is pulled out from the first through-hole and the second through-hole when the first connector is detached from the board-side connector.

10. The information processing apparatus according to claim 5 , further comprising a lock mechanism that suppresses a relative misalignment between the lower unit and the upper unit in a planar direction of the lower unit and the upper unit in a state in which the first connector is fitted to the board-side connector.
