Further, an arc-shaped cam 8 is formed at the base end of the display section 3 on the shaft 5 side. Furthermore, a hook 9 is provided near the bottom of the lock button 6 so as to be rotatable about a shaft 10, and is biased counterclockwise in the figure by a spring 11. A claw 9a is also formed at the tip of the hook 9.

Next, the operation of the locking mechanism will be explained. As shown in FIG. 2(a), when the electronic device is not in use with the display section 3 laid down on the electronic device main body 1, when the battery power supply section 2 is inserted into the power supply mounting section 1a in the direction c, the battery power supply The edge of the groove 2a of the part 2 presses the claw 6a of the lock button 6,
The lock button 6 is slightly lowered due to the elasticity of the spring 7. Then, the edge of the groove 2a rides over the claw 6a, the lock button 6 returns upward, and the claw 6a engages with the edge of the groove 2a, thereby locking the battery power supply section 2.

At this time, the cam 8 of the display section 3 is separated from the hook 9, and the hook 9 is rotated to the illustrated position by the bias of the spring 11, and is not engaged with the battery power supply section 2. Therefore, if the operator presses the lock button 6 in this state, the engagement between the claw 6a and the battery power supply section 2 is disengaged, and the battery power supply section 2 can be pulled out in the direction d and removed from the electronic device main body 1.

Next, in order to use the electronic device from the state shown in FIG. 2(a), when the operator rotates the display unit 3 in the direction b as shown in FIG. 2(b) and stands it up, the cam 8 rotates and pushes the hook 9, and the hook 9 rotates clockwise as shown by arrow e. Then, the claw 9a of the hook 9 engages with the groove 2b of the battery power supply section 2, and thereby the battery power supply section 2 is also engaged and locked.

Therefore, even if the operator presses down the lock button 6 in this state and the claw 6a disengages from the battery power source section 2,
Since the hook 9 engages and locks the battery power supply section 2, the battery power supply section 2 cannot be pulled out in the direction d. To pull out the battery power supply unit 2, move the display unit 3 to (b) in Figure 2.
) from the position to the position (a), rotate the hook 9 counterclockwise to disengage the hook 9 from the battery power supply section 2,
The lock of the battery power supply section 2 by the hook 9 is released, and the lock button 6 is also pushed down to release the lock by the lock button 6.

As described above, in this embodiment, when the electronic device is not in use, the battery power supply section 2 can be unlocked and removed by pressing the lock button 6, but when the electronic device is in use, the lock button 6 is pressed down. Even if the button is pressed, the lock is not released and the battery power supply section 2 cannot be pulled out. Therefore, while using an electronic device, an operator may accidentally disconnect the battery power supply section 2.
This prevents problems such as errors and data destruction due to removal during use, that is, power cut-off.

Second Embodiment Next, FIG. 3 is a cross-sectional view of a locking mechanism for a battery power supply section of an electronic device according to a second embodiment of the present invention, in a non-use state and a use state. The mechanism in FIG. 3 is assumed to be used similarly to the electronic device explained in FIG. 1, and in FIG.
Portions common or equivalent to the inside are given the same reference numerals, and explanations of the common portions will be omitted.

In FIG. 3, the difference from the first embodiment is that the lock slider 12 is bent into a crank shape.
is provided near the bottom of the lock button 6 so as to be slidable in the left-right direction. A rack portion 12a is formed on the lock slider 12, and an intermediate gear 13 meshes with this rack portion 12a. Further, the intermediate gear 13 meshes with a gear portion 3a formed on the outer periphery of the base end portion of the display portion 3.

On the other hand, the lock button 6 similarly has a claw 6a, is fitted into a cylindrical guide portion 1b formed in the electronic device main body 1 so as to be slidable up and down, and is pushed upwardly by a spring 7. energized. Note that the battery power source section 2 is provided with only a groove 2a in which the pawl 6a of the lock button 6 engages as a groove for locking the battery power source section 2.

Next, the operation of the locking mechanism of this embodiment will be explained. When the battery power supply section 2 is inserted into the power supply mounting section 1a in the direction c when the electronic device is not in use, as shown in FIG. As a result, the edge of the groove 2a of the battery power supply section 2 passes over the claw 6a of the lock button 6, the claw 6a engages with the edge of the groove 2a, and the battery power supply section 2 is locked.

At this time, the lock slider 12 is in a position where it does not interfere with the lock button 6, and the lock button 6 can be moved up and down. Therefore, in this state, the operator presses the lock button 6.
By pressing down, the engagement between the claw 6a and the battery power supply section 2 is disengaged, and the battery power supply section 2 can be pulled out in the direction d and removed from the electronic device main body 1.

Next, in order to use the electronic device from the state shown in FIG. 3(a), the operator rotates the display unit 3 in the direction b and stands it up as shown in FIG. 3(b). The intermediate gear 1 is rotated by the counterclockwise rotation of the gear part 3a as the gear part 3 rotates.
3 rotates in the direction of arrow f. As a result, the lock slider 12 is moved in the direction of arrow g, and the tip of the lock slider 12 protrudes along the lower surface of the lock button 6, making it impossible for the lock button 6 to move up and down. That is, the lock button 6 is locked.

Therefore, even if the operator presses the lock button 6 in this state, the lock button 6 does not come down and the battery power supply section 2 cannot be unlocked, and the battery power supply section 2 is not connected to the power supply mounting section 1.
It cannot be extracted from a. To pull out the battery power supply unit 2, return to the state shown in FIG. 3(a), unlock the lock button 6, and then press the lock button 6 to unlock the battery power supply unit 2.

As described above, according to the present embodiment, when the electronic device is in use, the lock button 6 that locks the battery power supply unit 2 is locked, so as in the first embodiment, when the electronic device is in use, the lock button 6 itself is locked. The battery power supply unit 2 will not be pulled out by mistake, and problems such as errors and data destruction caused by the pulling out can also be prevented.

In the configurations of the first and second embodiments described above, the hook 9 or the lock slider 12 is connected to the display section 3.
Although the operation is not limited to this, for example, the open/closed state (standing state, fallen state) of the display unit 3 can be detected using a micro switch or a photo sensor, and the detection result can be Accordingly, a lock member corresponding to the hook 9 or the lock slider 12 may be actuated by an actuator such as a solenoid.

[0028] Also, depending on the detection result of the open/closed state,
In the closed state, the display section 3 disappears and operation input from the keyboard 4 is also disabled; in the open state, the display is displayed and operation input is possible, and the battery power is turned off at the same time or before operation input becomes possible. By locking section 2, the risk of errors and data destruction can be further reduced.

[0029]

As is clear from the above description, according to the present invention, the battery power supply section is removably attached to the main body of the electronic device, and the display section is movably provided, making it easier to use the electronic device. In electronic devices that are moved to different positions when not in use and when not in use, a locking mechanism that is activated depending on the position of the display section releases the lock of the battery power supply section from the electronic device body when the electronic device is not in use. Although it can be removed, the battery power supply cannot be unlocked during use, and the battery power supply cannot be removed.This prevents the operator from accidentally removing the battery power supply while using the electronic device.
An excellent effect can be obtained in that problems such as occurrence of errors and data destruction due to removal during use, that is, power cutoff, can be prevented.
