Description

  The present invention relates to a mechanism for preventing an electronic device from falling off.

  Conventionally, when inserting an optical disc into an optical disc drive or the like, there is a slot-in type electronic device in which the optical disc is directly pushed into the optical disc drive, and some of such electronic devices prevent dropping when the optical disc is ejected. Some of them are provided with a drop-off prevention mechanism.

  However, such an electronic device drop prevention mechanism usually guarantees only the prevention of dropping of the optical disk being inserted / ejected, so that the user is exposed after the optical disk is exposed from the insertion slot by the ejection operation and the ejection operation is completed. May have fallen out of the apparatus before the optical disk is removed.

  Furthermore, the slot-in method, which was previously widely used in car stereo CDs, has recently been introduced in vertical PCs and DVD recorders, and may be used in digital video cameras in the future. Therefore, it is necessary to consider the possibility that the optical disc is ejected when the apparatus main body is in the vertical orientation or upside down, and the necessity for preventing the optical disc from dropping when ejecting the optical disc is higher than before.

For example, Japanese Patent Laid-Open No. 10-21618 discloses a possibility of dropping after an optical disk is ejected. In an optical disk player apparatus that can be slotted in, even if the optical disk is exposed from the insertion slot by the ejection operation, And the optical disk is prevented from falling out of the apparatus.
Japanese Patent Laid-Open No. 10-21618

  By the way, in a normal slot-in type electronic device, when an ejected disk is extracted, it is general that the finger is caught in an opening at the center of the disk. For this reason, considering the ease of taking out, as shown in FIG. 10, the disc needs to be ejected until at least the central opening is completely exposed. However, this means that more than half of the disk is exposed from the main body, and even if it is prevented from falling off by an urging member provided inside as in JP-A-10-21618, it is easy to remove. Considering the fact that it can not be energized with too much force, and that it can only energize the unexposed part of the disc, i.e. less than half of the disc, for example, it is accidentally ejected upside down There is a possibility that it will fall out. Further, as a method for more reliably preventing the dropout, there is a method in which a dropout prevention mechanism is provided outside the electronic device to hold the exposed portion of the disk, but this leads to an increase in the size of the electronic device.

  The present invention eliminates such a problem and does not impair the ease of taking out and does not cause an increase in size, and the user can read the optical disc after the optical disc is exposed from the insertion slot and the ejection operation is completed. An object of the present invention is to provide an electronic device having a drop-off prevention mechanism that can more reliably prevent the optical disc from falling off the electronic device until it is gripped.

  In order to solve the above problems, an electronic apparatus capable of inserting a recording medium by a slot-in method according to the present invention detects an insertion slot for inserting the recording medium and whether or not the recording medium is inserted. Detection means, a loading mechanism for loading the inserted recording medium, an operation button for ejecting the recording medium by the loading mechanism, and the disk ejection formed on the opening side of the insertion slot The electronic device is further provided with a member for preventing the recording medium from falling off inside the notch.

  According to the present invention, it is possible to reliably prevent the optical disk from dropping from the electronic device until the user grips the optical disk without impairing the ease of taking out or increasing the size. .

  Next, details of the present invention will be described in accordance with the description of the embodiments.

  As an effective embodiment of the present invention, a case where a slot-in method is applied to an optical disc camcorder will be described.

  1 and 2 show an external perspective view and a top view of the present invention. The electronic device 1 takes an image with the imaging unit 2 and records it on the optical disk inserted therein with the recording / control unit 3. The optical disk 7 serving as a recording medium for the recording can be inserted into the recording / control unit 3 by the slot-in method from the insertion slot 4 provided in the electronic device 1. The inserted optical disk 7 is detected by the detecting means provided inside the electronic apparatus 1 and can be recorded on the optical disk 7 by the recording / control unit 3. The operation button 5 is a press button that is disposed inside a notch 6 provided in the electronic device and ejects the optical disc 7 inserted into the recording / control unit 3. Further, the pressing surface 5 </ b> A of the operation button 5 is slightly smaller in area than the size of the opening hole 8 of the optical disk 7. 3 is a cross-sectional view taken along the line XX in FIG. FIG. 4 shows a YY cross-sectional view in FIG. 3 and 4, 9 is an operation button detection switch for detecting whether or not the operation button 5 is pressed, 10 is a disk detection switch for detecting whether or not an optical disk is inserted, and 26 is an optical disk 7 This is a loading completion detection switch for detecting that is inserted to a predetermined position. As shown in the example of FIG. 8, the detection switches are configured such that when the detected object 27 passes in front of the detection switch 28, the movable portion 29 of the detection switch 28 is pushed and the detection OFF / ON is switched. ing. In the present embodiment, all the detection switches are mechanical switches. However, the present invention is not limited to this, and may be detection means using, for example, an optical sensor. Also, as shown in FIG. 4, the disk detection switch 10 is arranged so that OFF⇔ON is switched when the optical disk 7 passes the position P2, and at this time, the center of the opening hole 8 of the optical disk 7 is switched. Substantially coincides with the center of the operation button 5.

  Reference numeral 11 denotes a lock member for preventing the operation button 5 from popping out when the operation button 5 is pressed. The lock member 11 is movable up and down via the motor 25. Further, the operation button 5 receives a biasing force in the pop-out direction by a spring 14 attached to a protrusion 13 provided inside the main body when locked. The stopper portion 23 provided on the operation button 5 abuts against the abutting surface 24 of the main body cover when the operation button 5 pops out, thereby restricting the pop-out position of the operation button 5. The main body protrusion 13 is always fitted to the hole 22 of the operation button 5 to some extent regardless of the position of the operation button 5, and also serves as a guide for the operation button 5. The insertion slot 4 is composed of base chassis 15a and 15b, and a sheet material 19 made of a friction member is stuck inside 15a. Inside 15b, guide rollers 16a and 16b, which are also friction members, are fixed to the roller shaft 17 with a space slightly smaller than the diameter of the optical disk 7, and are rotated integrally with the roller shaft 17. When the disc insertion / ejection operation is performed by the loading mechanism, loading is performed while pressing the disc 7 against the sheet material 19. The turntable 18 can be moved in the α⇔β direction in FIG. 3. When the disc is inserted, the turntable 18 moves in the β direction and is clamped with a clamper (not shown). When the disc is ejected, the turntable 18 moves in the α direction. The clamp is released.

  Note that a loading mechanism and a clamping mechanism, which are general slot-in mechanisms, are not the gist of the present invention, and thus description thereof is omitted here.

  Next, the flow of the embodiment of the present invention will be described with reference to the flowcharts of FIGS.

  When the optical disk 7 is inserted (see FIG. 11): When the optical disk 7 is not inserted into the recording / control unit 3, the operation button 5 is moved by the stopper member 11 at a position Q1 before the insertion slot 4 as shown in FIG. The pop-out is restricted, and the optical disc 7 is not prevented from being inserted into the insertion slot 4. In this state, when the optical disk 7 is inserted into the insertion slot 4 (S101), the detection switch 10 detects the insertion of the disk when the optical disk 7 passes the position P2 in FIG. 4 (S102), and the loading mechanism is activated to guide the roller. 16a and 16b rotate and loading of the optical disk 7 is started (S103). When the optical disk 7 is loaded to the predetermined position P3, the loading completion detection switch 26 is turned on and loading is stopped (S105). At the same time, the turntable 18 of FIG. 5 protrudes in the β direction and is clamped with a clamper (not shown) (S106), and the motor 25 is driven to move the lock member 11 downward (S107). Thereby, the operation button 5 protrudes to a position Q2 where the slot hole 4 is closed by the urging force of the spring 14 (S108).

  When the optical disc 7 is ejected (see FIG. 12): As shown in FIG. 6, when the operation button 5 is pressed while the optical disc 7 is inserted, the operation button detection switch 9 is turned on by the protrusion 12 of the operation button 5. Then, the pressing of the operation button 5 is detected (S201), and the motor 25 is driven to move the stopper member 11 upward and engage with the protrusion 12 of the operation button 5. As a result, the pop-up of the operation button 5 is restricted at the position Q1. At the same time, the turntable 18 is retracted in the α direction to release the clamp (S203), the guide rollers 16a and 16b are rotated in the reverse direction, and the unloading of the optical disk 7 is started (S204). The optical disk 7 is fed in the discharge direction by the guide rollers 16a and 16b until the position P2 in FIG. 4, that is, until the disk detection switch 10 is turned off. When the optical disk detection switch 10 is turned OFF, the unloading of the optical disk 7 is stopped (S206). At the same time, the stopper motor 25 is driven to move the stopper member 11 downward (S207). It jumps out by the urging force and penetrates through the disk opening hole 8 (FIG. 7, S208). Therefore, even if the electronic device 1 is pushed upside down and the operation button 5 is pushed to eject the optical disc 7, the operation button 5 is engaged with the opening 8 of the optical disc 7, so that the optical disc 7 is dropped from the electronic device 1. Will not fall. In order to remove the optical disk 7 from the state of FIG. 7, the thumb is inserted into the opening 8 of the optical disk 7 while pushing the operation button 5 to release the engagement state with the opening 8 of the optical disk 7 as shown in FIG. Then, the optical disk 7 is removed. At this time, the operation button 5 is locked again by the stopper member 11 and stopped at the position after being pressed by the same procedure as described above (S210).

  As described above, according to the present invention, the drop prevention mechanism is provided with a notch for taking out the disc at the upper part of the insertion slot, and a stopper member for preventing the drop of the optical disc is provided inside the notch. The optical disc is surely removed from the electronic device after the optical disc is exposed from the insertion slot and the ejecting operation is completed until the user grips the optical disc. Can be prevented.
