A second opening section 17 is formed in the inner surface 15a of the second casing 15. In the folded state, the inner surface 15a is opposed to the first unit 3. The second opening section 17 permits the screen 16a of the display module 16 to be exposed to the outside of the second unit 4.
The installation portion 25 is provided with a holding portion 26. A module unit 27 is arranged on the installation portion 25 in the state where it is surrounded by the holding portion 26. A fixing member fixing member 28 is attached to the holding portion 26 in such a manner that it covers the module unit 27. The holding portion 26, the module unit 27 and fixing member 28 will be described in detail.
The module unit 27 is contained inside the first casing 10. The module unit 27 is very small in comparison with the personal computer 1. The size of the module unit 27 is determined in accordance with the size and the manner of application of the personal computer 1.
The module unit 27 comprises a first side face 35, a second side face 36 (shown in
The second side face 36 is opposite the first side face 35. The first bottom face 37 is curved. The second bottom face 38 is flat and is projected from the first bottom face 37.
The first bottom face 37 and the second bottom face 38 are opposed to the installation portion 25. The first bottom face 37 is located in a side of one end 31a of the cover member 31. The second bottom face 38 is located in a side of the other end 31b of the cover member 31. The top face 39 is located opposite the first bottom face 37 and second bottom face 38.
The module 32 is a so-called vibrating motor. As shown in
The rotating shaft 43 extends from one end 41a of the trunk portion 41 and coaxial with the trunk portion 41. The eccentric weight 44 is attached to the rotating shaft 43. The overhang portion 42 is provided at the other end 41b of the trunk portion 41. The overhang portion 42 is projected outward from the outer circumference of the trunk portion 41.
The cables 33 extend from the other end 41b of the trunk portion 41. As shown in
The cover member 31 is formed of an elastic material such as synthetic rubber. The cover member 31 forms the first side face 35, second side face 36, first bottom face 37, second bottom face 38 and top face 39 of the module unit 27.
The cover member 31 is provided with a projection 47, a hole section 48, an extended portion 49, and an engagement portion 51 (shown in
The projection 47 is projected from the first side face 35 at a position close to the top face 39. As shown in
The extended portion 49 is projected from the other end 31b of the cover member 31. The second bottom face 38 of the module unit 27 is continuous with the extended portion 49. The end of the extended portion 49 is located outward of the end of the module 32.
The engagement portion 51 is depressed from the inner circumferential surface 31c of the cover member 31 that defines the hole section 48. The engagement portion 51 is located adjacent to the extended portion 49. It should be noted that the engagement portion 51 may be provided at another position on the inner circumferential surface 31c of the cover member 31 or may be provided for the extended portion 49.
The trunk portion 41 of the module 32 is inserted into the hole section 48 from the other end 31b of the cover member 31. When the trunk portion 41 is inserted into the hole section 48, the overhang portion 42 comes into engagement with the engagement portion 51. Since the overhang portion 42 is engaged or latched by the engagement portion 51, the module 32 is prevented from slipping off the hole section 48.
The first rib 55, second rib 56 and third rib 57 protrude from the installation portion 25. The first rib 55, second rib 56 and third rib 57 may be integral with one another. The first rib 55, second rib 56 and third rib 57 surround the module unit 27 mounted on the installation portion 25.

As shown in
The distal end 55a of the first rib 55 is an example of a peripheral region of the holding portion. The fitting portion 61 is not limited to the distal end 55a but may be provided at another portion of the first rib 55. The first rib 55 has a pair of edge portions 62 that define the fitting portion 61.
The edge portions 62 are provided in such a manner that they are more away from each other at positions closer to the distal end 55a of the first rib 55. Because the edge portions 62 have such a structure, the fitting portion 61 forms a substantial triangle having its apex orientated toward the installation portion 25. The shape of the fitting portion 61 corresponds to that of the projection 47 of the cover member 31.
Since the shape of the fitting portion 61 corresponds to that of the projection 47, the projection 47 comes into contact with the edge portions 62. It should be noted that the shape of the projection 47 may be different from that of the fitting portion 61. The projection 47 inside the fitting portion 61 is exposed to the outside of the holding portion 26.
As shown in
The first rib 55 includes a pair of first claws 55b. The first claws 55b protrude from the first rib 55 in a direction away from the module unit 27. The second rib 56 includes a second claw 56a. The second claw 56a protrudes from the second rib 56 in a direction away from the module unit 27.
The fixing member 28 is formed, for example, by bending a metallic plate. The fixing member 28 covers the top face 39 of the module unit 27 and is fixed to the holding portion 26. The fixing member 28 fixes the module unit 27 in such a manner that the module unit 27 is held by the holding portion 26.
The fixing member 28 is provided with a plurality of engagement holes 64. The engagement holes 64 are provided at positions corresponding to the claws 55b and second claw 56a. The first claws 55b and second claw 56a fit into the engagement holes 64.
The fixing member 28 is in contact with the top face 39 of the module unit 27 projected from the holding portion 26. The fixing member 28 presses the module unit 27 against the installation portion 25. Therefore, the fixing member 28 firmly fixes the module unit 27. When the module 32 is driven, this structure permits vibration to be reliably transmitted from the module 32 to the cover member 31.

As shown in
In the personal computer 1 having the above-mentioned structure, the fitting portion 61 is provided for the holding portion 26, which surrounds and holds the module unit 27. When the module unit 27 is held by the holding portion 26, the projection 47 of the module unit 27 fits into the fitting portion 61. The projection 47 is exposed to the outside of the holding portion 26.
When the module unit 27 is mounted on the mask member 21, the module unit 27 is pushed into the region between the first rib 55 and second rib 56 of the holding portion 26 in such a manner that the projection 47 is fitted into the fitting portion 61.
When the module unit 27 is mounted on the mask member 21 accurately, the projection 47 fits into the fitting portion 61. Since the projection 47 is exposed, it is easy to confirm whether or not the module unit 27 is accurately mounted on the mask member 21. In this manner, the module 32 is easily mounted in a predetermined state.
If the module unit 27 is pushed toward the holding portion 26 in an unintended direction or at an unintended position, the projection 47 may come into contact with the holding portion 26, for example. Alternatively, the projection 47 may be positioned away from the fitting portion 61. In this manner, the module unit 27 is prevented from being mounted in an undesirable manner.
The edge portions 62 are provided in such a manner that they are more away from each other at positions closer to the distal end 55a of the first rib 55. Since this structure permits the fitting portion 61 to be a substantial triangle, the projection 47 can be formed with a large manufacturing tolerance. Even the projection 47 prepared under such a manufacturing condition is reliably fitted into the fitting portion 61. In addition, the direction in which the module unit 27 should be pushed into the holding portion 26 is readily understood.
The module is not limited to a vibrating motor wherein an eccentric weight is attached to a rotating shift; it may be a vibrating motor having a disc shape. In addition, the module is not limited to a motor but an actuator, a speaker, etc.
