A locking protrusion 51 is formed to be locked to a locking member 26 formed on the operation piece 34 of the slide switch 17.

As shown in the fifth figure, the locking protrusion 51 consists of a support portion 52 extending from the lid 13 toward the circuit board 27, and a locking portion 53 extending from the end of the support portion 52 in the direction of arrow B. It is formed into a hook shape. This locking projection 51 forms a locking hole 61 that opens toward the downstream side in the direction of arrow B from the lid 13 and the locking portion 53 . Note that the locking protrusion 51a of the lid 14 has the same configuration as the locking protrusion 51, but the locking portion 53a extends in the direction opposite to the arrow B direction, and faces in the opposite direction to the locking protrusion 51. Formed in a hook shape. This locking protrusion 51a is connected to the lid 14.

The operation of the slide switch 17 will be explained with reference to FIGS. 5, 11, and 12.

FIG. 11 and FIG. 12 are diagrams showing a state in which the slide switch 17 is placed at the neutral position N. In this state, the sliding parts 48 and 49 of the spring 35 provided on the slide switch 17 are in contact with the contacts 36 and 37 of the circuit board 27,
The two contacts 36 and 37 are electrically connected via the spring 35. Therefore, the necessary condition for the power supply of the computer 11 to be turned on is satisfied.

Further, the locking member 26 provided on the operation piece 34 of the slide switch 17 is locked in both the locking holes 61, 61a of the locking protrusions 51, 51a formed on the lids 13, 14, and in this state Now, lid 13,1
4 cannot be removed from the computer 11 and is in a so-called locked state.

11 and 12 are diagrams showing the state in which the slide switch 17 is slid to the upper position U in FIG. 2. In this state, the spring 35
The sliding parts 48 and 49 are sliding in the direction of arrow E (see Fig. 11) from the neutral position N, and the two contact points 3
6 and 37 lose the means to be electrically connected. Therefore, the power to the computer 11 is cut off.

Further, the locking member 2 of the slide switch 17
6 is locked in the locking hole 61a of the lid 14, and the lid 14
is locked. On the other hand, the locking member 26 is removed from the locking hole 61 of the lid 13, and the lid 13 is unlocked.

11 and 12 are diagrams showing the state in which the slide switch 17 is slid to the lower position D in FIG. 2. In this state, spring 3
The sliding parts 48 and 49 of No. 5 are sliding in the direction of arrow F (see FIG. 11) from the neutral position N, and the two contacts 36 and 37 lose the means for electrical connection. Therefore, the power to the computer 11 is cut off.

Furthermore, the locking member 26 of the slide switch 17 is
The cover 13 is engaged with the engagement hole 61 of the cover 13, and the cover 13 is locked. On the other hand, the locking member 26 is removed from the locking hole 61a of the lid 14, and the lid 13 is unlocked.

FIG. 13 shows the lid 13 and memory module 1.
5 is a diagram showing a process of removing the computer 5 from the computer 11. FIG.
When the lid 13 is attached to the computer 11, one end has the locking protrusions 19 and 24 as described above.
The other end is locked to the locking member 26 of the slide switch 17 by a locking protrusion 51. In this state, the slide switch 17 is at the neutral position N.
(See Fig. 12 1) (Here, lid 1
4 is also attached to the computer 11).
Next, move the slide switch 17 to the upper position U (12th
(see Figure 2). In this state, the lid 1
3 is unlocked, so the two locking protrusions 1
The end portion having the locking protrusion 51 is lifted up using the fulcrums 9 and 24.

That is, the support parts 53 and 62 of the two locking protrusions 19 and 24 are formed to form an obtuse angle with the lid 13 as described above, and as described above, these two
The free ends of the two locking protrusions 19 and 24 are fixed,
When no external force is applied to the lid 13, the lid 13 is restored to its original shape. In other words, when attaching the lid 13 to the computer 11, the two locking protrusions 1
An external force must be applied against the elastic force near 9 and 24.

Next, a procedure for installing the memory module 15 will be explained. First, when the end portion of the memory module 15 having the stepped portion 57 is inserted into the support member 22, the memory module 15 is tilted by the conductive rubber 29 as shown in FIG. Here, when the end portion of the memory module 15 having the stepped portion 56 is pressed down against the elastic force of the conductive rubber 29,
The end portion contacts the locking piece 58 of the slider 21, and the upper surface of the locking piece 58 in FIG.
2, the locking piece 58 is once forced to move to the left side in FIG. 13 because it is inclined in a direction closer to the circuit board 33. Next, when the stepped portion 56 of the memory module 15 passes this locking piece 58, the locking piece 58 is restored to its original position by the action of the elastic portion 59 and engages with the stepped portion 56 of the memory module 15. , locked. On the other hand, when the slider 21 is moved to the left side in FIG. 13 in this state, the end portion of the memory module 15 having the stepped portion 56 is lifted up by the elastic action of the conductive rubber 29.

In this way, the memory module 15 can be installed by simply supporting one end and then pushing the other end, and can be easily taken out by simply moving the slider 21.

Further, as described above, the lid 13 can be attached to the computer 11 by supporting one end thereof and then locking the other end with the locking member 26 of the slide switch 17, by simply sliding the slide switch 17. can be easily taken out.
The lid 14 can also be attached and removed in the same manner.

Furthermore, in this embodiment, for example, either one of the lids 13, 14 can be taken out individually. That is, when one lid is removed, the other lid is always locked, and both lids 13 and 14 are closed.
It is impossible for the two to surface at the same time. Furthermore, since the power is always cut off when one of the lids is removed, the power is always cut off when the memory module 15 is removed. Therefore, the memory inside the memory module 15 can be taken out without damaging it.

Further, according to this embodiment, the above-mentioned effect is achieved by using only one slide switch 17, which contributes to downsizing of the computer 11.

Effects As described above, according to the present invention, in an electronic device to which a pair of parts is installed, the pair of parts can be commonly locked, and any part of the pair of parts can be selectively locked. It becomes possible to cancel the release. Furthermore, while the power to the electronic device is cut off even if any of the parts is unlocked, the power to the electronic device is energized only when the pair of components are locked in common. can.

Therefore, in electronic equipment where it is desirable to keep the power off when selectively removing one of a pair of parts, this purpose can be achieved with a simple operation by using the mounting mechanism according to the present invention. can be achieved. In addition, a pair of parts lock/
The unlocked state is realized by one operating means, and the number of components installed in the electronic device can be reduced.
