As shown in FIGS. 3, 9 (a) and 9 (b), the battery housing 10 is provided with a plate-like positive electrode terminal 11 at one end and a coil spring-like negative electrode terminal 12 at the other end. . The positive electrode terminal 11 contacts the positive electrode of the battery B stored in the battery storage unit 10, and the negative electrode terminal 12 contacts the negative electrode of the battery B.
In addition, as shown in FIG. 9A, the battery storage unit 10 has a card storage unit 13 for storing a memory card M, which is a storage medium for storing various data, under the space in which the battery B is stored. Is provided.
In particular, the battery housing portion 10 is provided with a cover member 30 that covers the inner surface thereof.
The cover member 30 is a member made of an elastic material such as rubber rubber and interposed between the battery storage unit 10 and the battery B, for example. As shown in FIGS. 10 (a) and 10 (b), a total of four engaging pieces 31 are formed on each side surface of the cover member 30, and the engaging pieces 31 are inserted into the battery storage unit 10. The cover member 30 is attached to the battery housing part 10 by being inserted into a hole (not shown).

As shown in FIGS. 10A and 10B, the cover member 30 has a curved surface that follows the peripheral surface of the cylindrical battery B on its upper surface, and is below the battery B stored in the battery storage unit 10. It is designed to cover one side. Since the cover member 30 is attached to the battery housing portion 10, the battery B is prevented from directly touching the battery housing portion 10 made of a relatively hard resin material such as PC / ABS alloy.
The cover member 30 is provided with an opening 32 for exposing the card storage portion 13 of the battery storage portion 10, and the memory card M can be attached to and detached from the card storage portion 13 through the opening 32. ing.
Further, a movement restricting portion 33 that restricts the movement of the battery B toward the negative electrode terminal 12 is provided on the negative electrode terminal 12 side of the cover member 30. The movement restricting portion 33 is a portion formed relatively thick in the cover member 30. The movement restricting portion 33 comes into contact with the negative electrode of the battery B and prevents the battery B from contracting the coil spring-like negative electrode terminal 12 by a predetermined amount or more, so that the positive electrode and the positive electrode terminal 11 of the battery B are not in contact with each other. I am doing so.
A mark indicating the direction of the battery B stored in the battery storage unit 10 is marked on the upper surface of the cover member 30.

As shown in FIG. 3, for example, four cushion members 40 made of an elastic material such as sponge or rubber rubber are attached to the inner surface of the battery lid 20 that closes the battery storage unit 10 with a double-sided tape.
In a state that closes the battery compartment 10 accommodating the battery B in the battery lid 20, as shown in FIG. 8 (b), the battery B is sandwiched between the cover member 30 and the cushion member 40, the battery housing portion 10 and the battery lid 20 so as not to come into contact therewith.

As described above, the electronic device 100 stores the battery B in the state where the battery B is sandwiched between the cover member 30 and the cushion member 40 so that the battery B does not contact the battery storage unit 10 and the battery lid 20. For example, even if the electronic device 100 is accidentally dropped, the impact is difficult to be transmitted to the battery B, and the internal battery B is not damaged due to the impact of the electronic device 100 dropping.
In addition, since the impact such as dropping is hardly transmitted to the battery B inside the electronic device 100, the battery B is difficult to move or shift, and the occurrence of power interruption can be reduced. In particular, since the movement restricting portion 33 provided on the negative electrode terminal 12 side of the cover member 30 restricts the battery B from moving to the negative electrode terminal 12 side, the power interruption can be further reduced.

The cushion member provided on the inner surface of the battery cover 20 is not limited to the rectangular shape as shown in FIG.
For example, as shown in FIG. 11, a cushion member 44 that is shaped like the cover member 30 may be disposed on the inner surface of the battery lid 20.
The cushion member 44 has a curved surface that follows the peripheral surface of the cylindrical battery B on its lower surface, and covers the upper half of the battery B stored in the battery storage unit 10.
Then, as shown in FIG. 12, in the state where the battery storage unit 10 storing the battery B is covered with the battery lid 20, the battery B is formed by the cover member 30 and the cushion member 44 except for the opening 32 portion of the cover member 30. It covers the area that goes around the circumference of the. That is, the entire circumference of the peripheral surface on the positive electrode side and the peripheral surface on the negative electrode side of the battery B accommodated in the electronic device 100 is covered with the cover member 30 and the cushion member 44.
As described above, if the cover member 30 and the cushion member 44 have a structure that covers the entire circumference of the battery B, the battery housing portion 10 and the battery lid 20 are further in contact with the battery B. It becomes difficult and it can be set as the structure which is hard to transmit an impact to the internal battery B more.

Next, a description will be given of a lock structure that locks the battery lid 20 that covers the battery housing 10 to the rear case 2.

  As shown in FIG. 3, a tongue 21 is provided on one end side of the battery lid 20, and locked portions 22, 22 are provided on the other end side. As shown in FIGS. 2A and 2B, the rear case 2 of the electronic device 100 is provided with a left lock portion 80 and a right lock portion 90 for locking the battery lid 20.

As will be described later, the switch 60 has a function of detecting the position of the detected portion 83 of the left lock portion 80 and detecting that the battery lid 20 is openable.

  Then, the user pinches the operation unit 81 of the left lock unit 80 and rotates the operation unit 81 to rotate and move the engagement unit 82, and the engagement position shown in FIGS. It can switch to the open position shown to 15 (a) (b). Further, along with the operation of rotating the operation portion 81, the detected portion 83 and the claw portion 84 can be rotated in conjunction with the locking portion 82, and the positions thereof can be switched.

As shown in FIG. 13, the right lock portion 90 includes a locking portion 92 that locks the locked portion 22 of the battery lid 20, and an operation portion that switches the locking portion 92 between a locking position and an open position by a user operation. 91 and a claw portion 94 that moves in conjunction with the locking portion 92. A protrusion 94 a is formed at the tip of the claw portion 94.
The right lock portion 90 is composed of two parts. The operation portion 91 and the locking portion 92 are integrally molded to constitute one part, and the claw portion 84 constitutes the other part. As shown in FIGS. 14 and 15, one part having the operation portion 91 and the locking portion 92 is arranged on the outer surface side of the rear case 2, and the other part having the claw portion 94 is on the inner surface side of the rear case 2. One part and the other part are screwed in a predetermined direction and are pivotally attached to the rear case 2.

  Then, the user picks up the operation unit 91 of the right lock unit 90 and rotates the operation unit 91 to rotate and move the engagement unit 92, and the engagement position shown in FIGS. It can switch to the open position shown to 15 (a) (b). Further, in accordance with the operation of rotating the operation portion 91, the claw portion 94 can be rotated and moved in conjunction with the locking portion 92 to switch its position.

In the electronic device 100 including the left lock portion 80 and the right lock portion 90 as described above, the battery cover is in a state where both the locking portion 82 of the left lock portion 80 and the locking portion 92 of the right lock portion 90 are in the open position. 20 is mounted on the rear case 2 of the electronic device 100, the operation portion 81 of the left lock portion 80 is turned clockwise to switch the lock portion 82 to the lock position, and the operation portion 91 of the right lock portion 90 is turned counterclockwise. The battery lid 20 is locked by turning the locking portion 92 to the locking position.
When the locking portions 82 and 92 are switched from the open position to the locking position, the locking portions 82 and 92 are inserted into the grooves of the locked portions 22 and 22 of the battery lid 20, and the locking portions 82 and 92 are inserted. The locked portions 22 and 22 are in a fitted state, and the locking portions 82 and 92 lock the battery lid 20 so that the battery lid 20 is locked.

Further, as shown in FIGS. 14B and 15B, the movement range of the claw portion 84 of the left lock portion 80 and the movement range of the claw portion 94 of the right lock portion 90 on the inner surface side of the rear case 2 are as follows. In each case, two convex portions 2b are provided.
Then, when the left and right operation portions 81 and 91 are respectively operated and the claw portions 84 and 94 are rotated in conjunction with the locking portions 82 and 92, the protrusions 84a and 94a of the claw portions 84 and 94 are formed on the convex portion 2b. The claw portions 84 and 94 are elastically deformed to move over the convex portion 2b.
When the claw portions 84 and 94 get over the convex portion 2b, the claw portions 84 and 94 that have been elastically deformed are restored so as to be repelled, thereby generating a click sound.
That is, when the operation portions 81 and 91 are operated to switch the locking portions 82 and 92 from the locking position to the open position, or from the open position to the locking position, the claw portions 84 and 94 get over the two convex portions 2b. Therefore, two clicks are made with “click”.
Thus, when the user operates the operation units 81 and 91, a click sound is generated by switching the positions of the claw portions 84 and 94 in accordance with the operation, and the user obtains the click feeling, whereby the left lock unit 80 and It can be felt that the operation of locking or unlocking the battery lid 20 by the right lock unit 90 has been performed.

  Next, operations and processing when removing the battery cover 20 of the electronic device 100 will be described.

In a state where the user uses the electronic device 100, as shown in FIG. 2A, the battery lid 20 closes the battery housing portion 10, is attached to the rear case 2 of the electronic device 100, and further, the left lock portion. 80 and the right lock portion 90 are switched to the locking position, and the locked portions 22 and 22 of the battery lid 20 are locked by the locking portion 82 and the locking portion 92 to lock the battery lid 20. At this time, the detected portion 83 of the left lock portion 80 is in the position shown in FIGS. 16 (a) and 17 (a).
If the battery cover 20 is locked as described above, even if the electronic device 100 is accidentally dropped during use, the battery cover 20 cannot be removed due to an impact such as dropping.

Then, when removing the battery cover 20 in order to replace the battery B or remove the memory card M, the operating portion 81 of the left lock portion 80 in the locking position is rotated counterclockwise, and the locking portion 82 is switched from the locked position to the open position. Similarly, the operation part 91 of the right lock part 90 in the locking position is rotated clockwise to switch the locking part 92 from the locking position to the open position.
Since the locking portion 82 and the locking portion 92 are switched to the open position, the locking portion 82 and the locking portion 92 are disengaged from the locked portions 22 and 22 of the battery lid 20 to unlock the battery lid 20. Thus, the battery lid 20 is in a state where it can be opened.

In particular, when the operation portion 81 of the left lock portion 80 is operated and the locking portion 82 is switched from the locking position to the open position, the detected portion 83 interlocked with the locking portion 82 is shown in FIG. It moves to the position shown in FIG. 17B and pushes down the lever 61 of the switch 60.
And the control part 3b of the electronic device 100 detects that the to-be-detected part 83 and the latching | locking part 82 exist in an open position by the lever 61 of the switch 60 being pushed down, and the battery cover 20 can be opened. Judge that it is in a state.
When the control unit 3b detects that the locking unit 82 is in the open position and the battery cover 20 is openable, the electronic device 100 (the control unit 3b) transmits data to the memory card M. Write and execute processing to prepare for power shutdown. By writing data to the memory card M at this timing, data loss can be avoided.
The electronic device 100 (the control unit 3b) supplies signals to various electronic components and elements mounted on the circuit board 3 as a process for preparing for power shutdown in addition to writing data to the memory card M. Is turned off, and processing for ending the operation of the circuit board 3 is executed. By this processing, it is possible to avoid a failure or the like caused by suddenly turning off the power supply during various operations of the electronic device 100. When the detected portion 83 and the locking portion 82 are switched to the locking position and the lever 61 of the switch 60 is returned to the position shown in FIGS. 16 (a) and 17 (a), the circuit board 3 and the like are powered. Supply is resumed.

As described above, in the electronic device 100, the battery cover 20 that has closed the battery storage unit 10 is locked by the left lock unit 80 and the right lock unit 90, and the battery cover 20 is removed due to an impact that has dropped the electronic device 100. Therefore, it is possible to prevent the power supply from being cut off such that the battery cover 20 is detached and the battery B is dropped due to a drop impact or the like.

In particular, when operating the left lock portion 80 and the right lock portion 90 as an operation of removing the battery cover 20, here, the operation portion 81 of the left lock portion 80 is operated to switch the lock portion 82 from the lock position to the open position. At this time, the electronic device 100 (the control unit 3b) can write data to the memory card M, triggered by the fact that the detected unit 83 interlocked with the locking unit 82 depresses the lever 61 of the switch 60. .
That is, the electronic device 100 can write data to the memory card M before opening the battery cover 20, and the data is stored in the memory card M before removing the battery B from the battery storage unit 10. As a result, data writing is not hindered by sudden power interruption, and data loss can be prevented more reliably.

Further, the memory card M is accommodated in the card accommodating section 13 in the battery housing portion 10, since the portion where the battery B was overlaying, writing of data during the operation of the electronic device 100 (e.g., the memory card M The memory card M is not taken out during processing.
In particular, when the memory card M is taken out, the left lock portion 80 and the right lock portion 90 are operated as an operation for removing the battery lid 20, and as described above, the memory card is opened before the battery lid 20 is opened. Since data is written to M, data loss can be prevented more reliably.

As described above, according to the present embodiment, in the electronic device 100, the battery lid 20 that has closed the battery storage unit 10 is locked by the left lock unit 80 and the right lock unit 90, and the impact that has dropped the electronic device 100. Since the battery lid 20 is prevented from being removed by the above, it is possible to prevent the power supply from being cut off such that the battery lid 20 is detached and the battery B is dropped due to a drop impact or the like.
In particular, as an operation of removing the battery cover 20, when the operating portion 81 of the left lock portion 80 is operated to switch the locking portion 82 from the locking position to the open position, the detected portion 83 interlocked with the locking portion 82 is When the lever 61 of the switch 60 is pushed down, the electronic device 100 can write data to the memory card M. In other words, the electronic device 100 detects that the detected portion 83 has pushed down the lever 61 of the switch 60, thereby detecting that the locking portion 82 is in the open position and the battery lid 20 can be opened. Since the data can be written to the memory card M before the lid 20 is opened, the data is stored in the memory card M before the battery B is removed from the battery compartment 10. Data writing is not hindered by sudden power interruption, and data loss can be more reliably prevented.

  Further, when the electronic device 100 detects that the detected portion 83 has pushed down the lever 61 of the switch 60 and detects that the locking portion 82 is in the open position and the battery cover 20 is openable, Since the signal supply to various electronic components and elements mounted on the board 3 is turned off and the process of terminating the operation of the circuit board 3 is executed, the electronic device 100 is suddenly shut off during various operations. Failures can be avoided.

  Further, when the left and right operation portions 81 and 91 are respectively operated and the claw portions 84 and 94 are rotated in conjunction with the locking portions 82 and 92, the protrusions 84a and 94a of the claw portions 84 and 94 are formed on the convex portion 2b. Since the click sound is generated at the timing when the claw portions 84 and 94 get over the convex portion 2b by the collision, the user obtains the click sound and the click feeling, whereby the battery cover 20 by the left lock portion 80 and the right lock portion 90 is obtained. You can feel that you have performed the lock and unlock operations.

In the above embodiment, the operating portions 81 and 92 and the detected portion 83 are rotated and moved by rotating the operating portion 81 of the left lock portion 80 and the operating portion 91 of the right lock portion 90. Although the position is switched, the present invention is not limited to this, and by sliding the operation portion 81 and the operation portion 91, the locking portions 82 and 92 and the detected portion 83 are slid to move the position. May be switched.
The operation unit 81 and the operation unit 91 are rotated and slid along the case surface of the electronic device 100, and the locking units 82 and 92 are interlocked with the operation unit 81 and the operation unit 91 along the back surface of the case. If the position is switched by rotating or sliding the detected portion 83 or the detected portion 83, the position of the locking portions 82, 92 and the detected portion 83 is switched from that in the thickness direction of the electronic device 100. The electronic device 100 can be thinned.

  In addition, it is needless to say that other specific detailed structures can be appropriately changed.

Although several embodiments of the present invention have been described, the scope of the present invention is not limited to the above-described embodiments, but includes the scope of the invention described in the claims and equivalents thereof.
