Specifically, when the user operates the stop button at the end of storing the information in the disk-shaped storage medium, the storage of the information is stopped, and then the TOC information is written.

In such a system, if the lid is opened during the storage of information in the disk-shaped storage medium,
Since the information storage operation is interrupted before the stop button is operated and the TOC information is not written, it is sometimes impossible to read and reproduce the information.

In the conventional portable storage / playback device provided with a waterproof measure, as described above, the means for holding the lid in the closed position is not provided except for the pressing member, so that the storage medium for the disk-shaped storage medium can be used. Even while storing the information of
When the pressing of the lid member by the pressing member is released, the lid member rotates to the open position and the storage medium mounting portion of the main body portion is opened, so that the information storage operation is interrupted.
Therefore, since the TOC information is not written, there is a problem that the information cannot be read and reproduced.

In view of the above problems, it is an object of the present invention to prevent the lid part from being opened during storage of information in a storage medium in an electronic device that is waterproofed.

[0010]

In order to solve the above-mentioned problems, the present invention provides a main body part in which a storage medium is mounted, and a closed position for closing the main body part and an open position for opening the main body part. A housing having a lid rotatable with respect to the main body, a pressing member that presses the lid to press the main body at the closed position of the lid of the housing, and a memory mounted inside the main body.

Locking means 1 for holding the lid 4 in the closed position
4 is provided inside the main body 3. The configuration and operation of the lock means 14 will be described below.

The locking means 14 for locking the lid portion 4 of the housing 2 at the closed position where the main body portion 3 is closed has, for example, a configuration schematically shown below.

As shown in FIGS. 9 to 11, a lock lever 16 is movably supported in the left-right direction on the front surface of a chassis 15 on which a rotary drive unit, an optical pickup, etc. (not shown) are mounted. A lock claw 16a is provided so as to project from the upper edge. A compression coil spring 17 is bridged between the lock lever 16 and the chassis 15, and the compression coil spring 17 urges the lock lever 16 in the direction of arrow F in the figure. A regulated portion 16b projects rearward from the upper edge of the left end of the lock lever 16, and a switch pressing piece 16c projects rearward from the left end of the lock lever 16. ing.

An open lever 18 connected to the lid open lever 13 is rotatably supported on the front surface of the chassis 15 in the left-right direction, and the open lever 18 and the lock lever 16 are connected by a tension coil spring 19. Has been done. The urging force of the tension coil spring 19 is stronger than the extension force of the compression coil spring 17. Therefore, when the force in the direction of arrow G shown in FIG. 10 is not applied to the lid open lever 13, the open lever 18 and the lid open lever 13 are positioned at the left end in the movement range by the biasing force of the compression coil spring 17. is doing. An engagement member 4b that engages with the lock claw 16a of the lock lever 16 is provided on the inner surface of the front end of the lid 4 of the housing 2.

When the lid portion 4 of the housing 2 is rotated downward from the open position shown in FIG. 5, the engaging member 4b provided at the front end of the lid portion 4 and the lock claw 16a come into contact with each other to lock. Nail 16
By pressing a to the left, the lock lever 16 moves in the direction of arrow G while compressing the compression coil spring 17. When the lid 4 is further rotated downward, the engaging member 4b
The lock lever 16 moves in the direction of arrow F by the urging force of the compression coil spring 17 due to the contact between the lock claw 16a and the lock claw 16a, the lock claw 16a engages with the engaging member 4b of the lid part 4, and the lid part 4 moves. 1 and locked in the closed position shown in FIG.

When the lid 4 is unlocked at the closed position, the lid open lever 13 is moved to the right to open the open lever 18 and the tension coil spring 19.
The lock lever 16 is moved in the direction of arrow G via the lock claw 16a and the engagement member 4b of the lid 4 are disengaged,
The lid portion 4 is rotated to the open position by the urging force of a resilient means (not shown). At this time, since the biasing force of the tension coil spring 19 is made stronger than the biasing force of the compression coil spring 17, the tension coil spring 19 does not expand and the compression coil spring 1
7 is compressed and the lock lever 16 moves in the direction of arrow G. The open lever 18 and the lid open lever 13 are excluded except for the force applied to the lid open lever 13.
Is returned in the direction of arrow F by the urging force of the compression coil spring 17.

By the way, in the electronic apparatus 1 which uses a magneto-optical disk as a storage medium, the lid portion 4 cannot be opened while information is being stored in the magneto-optical disk. The lock means 14 is provided with a control lever 20 so that the lid portion 4 of the housing 2 cannot be opened during the storage of information on the magneto-optical disk.

As shown in FIG. 10, the control lever 20 is supported so as to be movable in the front-rear direction along the left side surface of the chassis 15, and has a rack 20a formed at the lower edge near the front end and at the front end. A regulation portion 20b is provided. The control lever 20 meshes with a pinion 21 driven by a drive motor (not shown).

When the storage of information on the magneto-optical disk is started, the pinion is rotated by the drive motor (not shown) in association with various operations such as movement of the optical pickup to the storage position, and the pinion 21 is racked. The control lever 20 is moved forward (in the direction of arrow H in FIG. 11) by driving 20a. When the control lever 20 moves forward, as shown in FIG. 10, the regulating portion 20b is located immediately to the left of the regulated portion 16b of the lock lever 16 and unlocks the lid portion 4 of the housing 2 in the closed position. As a result, it cannot be rotated to the open position.

That is, when the lid open lever 13 is operated during the storage of information on the magneto-optical disk, the lock lever 16 is pulled to the left via the open lever 18 and the tension coil spring 19, but the control lever 20 Since the regulating portion 20b is located immediately on the left side of the lock lever 16, the regulated portion 16b cannot come into contact with the regulating portion 20b and the lock lever 16 cannot move to the left. Since the engagement of the second lid portion 4 with the engagement member 4b is not released, the lid portion 4 is held in the locked state in the closed position.

By the way, if the TOC information is not written because the operation of storing information on the magneto-optical disk is interrupted, the stored information cannot be read and reproduced, and this problem must be avoided. .

The locking means 14 of the lid 4 and the control lever 20 which operate as described above constitute the rotation restricting means 22. The rotation restricting means 22 is provided in order to avoid a situation in which the stored information cannot be read and reproduced unless the TOC information is written due to the interruption of the information storage operation on the magneto-optical disk. It has been done. Therefore, when the rotation restricting means 22 is performing the storing operation on the storage medium by the storing / reproducing means including the recording magnetic head and the optical pickup, the pressing of the pressing member 7 on the lid portion 4 of the housing 2 is released. However, the rotation of the lid portion 4 is restricted and held at the closed position. Then, when the writing of the TOC information to the magneto-optical disk is completed, the rotation restricting means 22 controls the restricting lever 2
Since the restriction of the movement of the lock lever 16 by 0 is released, the lid open lever 13 is operated to release the engagement between the engagement member 4b of the lid 4 and the lock claw 16a of the lock lever 16, and the lid is opened. The part 4 can be opened.

Therefore, while the information is being stored in the magneto-optical disk, even if the lid opening lever 13 is operated, the rotation of the lid 4 is restricted by the rotation restricting means 22, so that the lid is closed. 4 is often released, and it is possible to avoid a situation in which the stored information cannot be read and reproduced, which is caused by the interruption of the information storage operation and the TOC information not being written.

When the lid opening lever 13 is operated, the locked state of the lid portion 4 of the main body housing 3 is released, and the lid portion 4 pivots the rear end portion by a biasing force such as a spring (not shown). As shown in FIG. 1, the disc cartridge 100, which will be described later, can be attached and detached by opening upward as shown by the two-dot chain line. When the lid 4 is closed from the open state, the lid 4 is locked and the lid 4 is held in the closed state.

Operation switch 2 having the above configuration
3 is a switch main body when the operated portion 31 is swung forward or backward, swung upward or downward, or pushed rightward by the first swing operation, the second swing operation and the pushing operation. Of the five contacts (not shown) of the unit 30, specific contacts are pressed and closed by the connecting unit 32, a command signal based on the operation is input to the system controller 106, and the electronic signals at the time of signal input in the system controller 106. The operating state of the device 1 (whether information is being reproduced or recorded) is determined, and a drive signal directed to a portion corresponding to the input command signal is transmitted.

The functions assigned to each operation of the operation switch 23 will be described below. The functions assigned to the five directional operations, that is, the first oscillating operation, the second oscillating operation of the operation switch 23, and the pressing operation in the direction orthogonal to these directions are performed by the system controller 106. Different functions are assigned to the operation depending on whether the electronic device 1 is reproducing the information or stopping the reproduction of the information.

That is, when the electronic device 1 is in the state of stopping the reproduction of information, the system controller 106 assigns the function only to the forward swing operation of the first swing operations of the respective operations of the operation switch 23. To be That is,
When the operated part 31 is swung forward, the reproduction of information is started. Therefore, even if the operated portion 31 is swung backward by the first swinging operation of the operation switch 23 or if the operated portion 31 is swung upward or downward by the second swinging operation, Even if the operated portion 31 is pressed to the right by the pressing operation, since no function is assigned to these operations, no operation instruction is issued from the system controller 106, and the electronic device 1 does not operate. No action is taken.

When the electronic device 1 is reproducing information,
The operation switch 2 is controlled by the system controller 106.
Different functions are assigned to all of the first rocking operation 3, the second rocking operation, and the pressing operation 3.

That is, the first swing operation of the operation switch 23 is assigned a function (track change) for selecting and switching the track in which the information to be reproduced is stored, and the second swing operation is the reproduction operation. The function of adjusting the volume is assigned, and the pressing operation is assigned the function of stopping the reproduction of information.

Therefore, when the operated portion 31 is swung forward, a track change is performed to switch the reproduction track on the magneto-optical disk 100b to the next track.
When the operated portion 31 is swung backward, a track change is performed to switch the reproduction track on the magneto-optical disc 100b to the previous track. When the operated portion 31 is swung upward, the reproduction volume is increased, and when the operated portion 31 is swung downward, the reproduction volume is decreased. Further, when the operated portion 31 is pressed to the right, the operation of each portion of the electronic device 1 is stopped and the reproduction of information is stopped.

When the electronic device 1 is reproducing information, in addition to the function of performing the track change in the first swing operation of the operation switch 23 by the system controller 106, the information fast-forward reproduction function (Cue : Cue) and the information fast replay function (Review) are assigned together. The four functions assigned to the first swing operation of these operation switches 23 are to swing the operated portion 31 in the front-back direction to temporarily close the corresponding contacts, or to move the operated portion 31 back and forth. It is distinguished by whether it is kept swung in the direction and the contact is kept closed.

That is, in the operation of swinging the operated portion 31 in the front-rear direction and temporarily closing the corresponding contact by the first swing operation of the operation switch 23, the function of performing the track change as described above is used. However, the operation of keeping the operated part 31 in the front-rear direction while swinging it and keeping the contacts closed is performed by keeping the operated part 31 in the swinging state. A function for fast-forward playback or fast-reverse playback of information is assigned only while the contact is closed.

Therefore, if the operated portion 31 is kept swinging forward, the information is reproduced while being fast forwarded while the operated portion 31 is held, and the operated portion 3 is held.
If the state in which 1 is oscillated backward is continued to be held, the information is reproduced while being rewound while the operated portion 31 is held.

Incidentally, during the reproduction of the information, when the swing of the operated portion 31 in each direction accompanying the first swing operation and the second swing operation of the operation switch 23 is finished,
It is supposed to start the reproduction of information.

As described above, the system controller 1
In consideration of the operation state of the electronic device 1, 06 indicates the information reproduction when the operation switch 23 performs the forward swing operation among the first swing operations while the information playback is stopped. When a first swing operation is performed on the operation switch during the reproduction of, the track change is instructed, and when the state in which the first swing operation is performed on the operation switch 23 is maintained, the information is fast-forwarded only during that time. Since the reproduction or the fast-reverse reproduction is instructed, it is possible to select and instruct an appropriate function according to the state of the electronic device even when the first swing operation is similarly performed on the operation switch 23. .

The electronic device 1 having the configuration as described above is used in the state as shown in FIGS. 16 and 17. The electronic device 1 is assumed to be used, for example, during jogging or walking, and the usability of the operation unit for performing various operations in that case is improved.

By the way, in the electronic device 1, one end (front end) 2a of the housing 2 is thicker than the other parts, and the operation switch 23 capable of intensively operating the most frequently used functions is provided. The front end portion 2a of the left side surface 2c of the housing
It is located on the side.

As shown in FIG. 16, when the user holds the housing 2 with the left hand, the front end portion 2a is thickened to improve the grip of the fingers so that the user can hold it with the palm and fingers. This is for facilitating the operation and for facilitating various operations using the operation switch 23 with the thumb in that state. Further, in the electronic device 1, as shown in FIG. 17, a strap 40 is attached to the lower surface 2d side of the housing 2.

When the electronic device 1 is used, for example, during jogging or walking, four fingers excluding the thumb of the left hand are inserted into the strap 40, and then, as shown in FIG. When the user bends his / her finger along the front end portion 2a and grasps the housing 2 with four fingers excluding the thumb and the palm, the thumb naturally reaches the operation switch 23. At this time, the electronic device 1 inserts four fingers excluding the thumb into the strap 40 to support the weight with the four fingers. Therefore, even if the fingers are opened, the electronic device 1 does not fall off and the thumb does not fall. The force of gripping the housing 2 with four fingers except the palm and the palm is hardly required.

As described above, the electronic device 1 uses the operation switch 23 capable of the first rocking operation, the second rocking operation, and the pressing operation to store in the magneto-optical disk 100b with one finger. Function to start playing back the information
Magneto-optical disk 100, a function of stopping the reproduction of the information
