Stick type input device attachment structure, stick type input device cap, stick type input device, information processing terminal apparatus, and stick type input device attachment method
An example stick type input device is attached to a main body portion, includes a columnar operation stick, and is for sensing, using a sensor, a content of an operation performed on the operation stick. With an attachment structure of attaching a cap of the stick type input device to the main body portion, the cap is attached to the operation stick so as to enclose an upper end thereof, and the cap is retained so as to resist against removal from the main body portion.
1. An information processing apparatus comprising:
a stick type input device, the stick type input device being attached to a main body portion, including a columnar operation stick, and being configured to sense, using a sensor, an operation performed on the columnar operation stick,
a cap attached to the columnar operation stick so as to enclose an upper end of the columnar operation stick, wherein
the cap includes an extended part extending in a direction transverse to an axis defined by the columnar operation stick,
the extended part includes a hole,
the main body portion includes a fixed boss, and
the hole and the fixed boss are mated together so as to resist against removal of the cap from the stick type input device and the main body portion.
2. The information processing apparatus according to claim 1 , wherein the cap is formed of an elastic body.
3. The information processing apparatus according to claim 1 , wherein:
the hole is sized to provide a gap around the fixed boss; and
the extended part is movable with respect to the main body portion while the fixed boss is inserted in the hole.
4. The information processing apparatus according to claim 1 , wherein the extended part is embedded within the main body portion.
5. The information processing apparatus according to claim 4 , wherein the extended part is embedded within the main body portion such that the extended part and the main body portion are overlapped when viewed parallel to the axis.
6. The information processing apparatus according to claim 4 , wherein the extended part is extended approximately orthogonal to the axis.
7. The information processing apparatus according to claim 4 , wherein:
the main body portion includes a base part on which the stick type input device is arranged, and an upper surface part connected to the base part while having a gap between the base part and the upper surface part; and
the extended part is embedded within the gap.
8. The information processing apparatus according to claim 7 , wherein:
the cap includes a circumferential surface part and a flange extending outward from an outer peripheral edge of an opening on a lower end side of the circumferential surface part; and
the extended part extends beyond the flange.
9. The information processing apparatus according to claim 1 , wherein the cap is retained by the main body portion so as to be movable in association with an operation performed on the stick type input device.
10. The information processing apparatus according to claim 1 , wherein the cap is irremovably retained by the main body portion.
11. A stick type input device comprising:
a columnar operation stick attached to a main body portion, and configured to sense an operation performed on the columnar operation stick,
a cap attached to the columnar operation stick so as to enclose an upper end of the columnar operation stick, wherein
the cap includes an extended part extending in a direction transverse to an axis defined by the columnar operation stick,
the extended part includes a through hole that is configured to mate with a fixed boss on the main body portion so as to resist against removal of the cap from the stick type input device and the main body portion.
12. A method of attaching a cap to a stick type input device on a main body portion, the stick type input device including a columnar operation stick, for sensing an operation performed on the columnar operation stick, the method comprising:
attaching the cap to the columnar operation stick so as to enclose an upper end of the columnar operation stick; and
attaching an extended portion of the cap such that a hole on the extended portion is mated with a fixed boss on the main body portion such that the cap is retained so as to resist against removal from the stick type input device and the main body portion.
