Abstract

PURPOSE:To easily fix an elevator mechanism to a reproducing position when a cassette deck is transported by equipping the title protector with a part to be detected which is detected by a detecting means, a projecting part to project from an inserting hole to an external part under the inserted state of the part to be detected, and a fixed part to be fixed with the elevator mechanism under a reproducing state and the other mechanisms. CONSTITUTION:An inserting part 2 is equipped with the function of the part to be detected and that of the fixed part, and when the part to be detected is inserted into a cassette inserting hole 9 of the cassette deck, and the inserted part to be detected is detected by a detecting means 11, and elevator mechanism 10 is moved and fixed. On the other hand, accompanying the moving of the elevator mechanism 10, the fixed part is fixed with the elevator mechanism 10 and the other mechanisms. Since a projecting part 3 is projected from the cassette inserting hole 9 under the state, the movement of an elevator can be confirmed, and a cassette half is never erroneously inserted into the cassette inserting hole 9. Thus, the elevator mechanism 10 can descend by inserting the inserting part 2 of a protector 1 into the cassette inserting hole 9, and the elevator mechanism 10 can be fixed to the descended position.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a protective device used during transportation of a cassette deck.

[Conventional technology]

The internal mechanisms of precision instruments such as cassette decks can be damaged by vibrations during transportation, and movable parts, such as elevator mechanisms that raise and lower cassette halves, are particularly susceptible to damage and must be fixed during transportation.

Conventionally, as a method of fixing this elevator mechanism, the sixth method is
As shown in the figure, ■ Fix the elm bake mechanism from outside the product with screws 21 while the elevator mechanism is raised, or ■ Insert a rod or the like into the cassette insertion hole to detect insertion of the cassette half and then close the elevator mechanism. There is a method of lowering the elevator mechanism in advance by operating a detection means such as a lever that lowers the elevator mechanism. This is a structure in which the elevator mechanism is fixed in a predetermined position when the elevator mechanism is in a descending state, that is, when the cassette deck is playing, fast forwarding, rewinding, or stopped, and this mechanism is used to fix the elevator mechanism. It is something to do.

In the method (2), it is necessary to remove the fixing screw 21 before using the cassette deck, so a label with a notice to remove the screw 21 is usually fixed using the screw 21.

[Problem that the invention seeks to solve]

However, in method (2), it takes time and effort to attach and remove the fixing screws 21 of the elevator mechanism. The cassette deck 6 also has screws 21 for fixing the elevator mechanism.
Since other screws are also used, if only the above-mentioned caution label comes off during transportation, you will not be able to tell the difference between the fixing screw 21 and the other screws. There is a possibility that it will destroy the cassette.

-Also, since method (■) lowers the elevator mechanism, there is a risk that the cassette half may be inserted into the power center insertion hole without noticing that the elevator mechanism is lowering, and the cassette half may become jammed inside. The cassette deck may be damaged.

The present invention solves these problems.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a cassette insertion hole, a detection means for detecting that a cassette half is inserted into the cassette insertion hole, and a reproduction of the cassette half in response to the output of the detection means. A transport protective device used for a cassette deck having an elevator mechanism for moving the cassette relative to a position, the detection portion being inserted into the cassette insertion hole and detected by the detection means, and the cassette insertion hole. The apparatus is characterized in that it has a protruding part that protrudes to the outside from the cassette insertion hole when the detected part is inserted into the hole, and a fixing part that is fixed by the elevator mechanism and another mechanism in the playback state.

[Effect]

When the detected part is inserted into the cassette insertion hole of the cassette deck and detected by the detection means, the elevator mechanism is moved and the elevator mechanism is fixed. On the other hand, as the elevator mechanism moves, the fixed portion is fixed by the elevator mechanism and other mechanisms.

In this state, since the protrusion protrudes into the cassette insertion hole, it can be confirmed that the elevator is moving, and the cassette half will not be erroneously inserted into the cassette insertion hole in this state.

[Embodiments of the invention]

Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a plan view showing a state in which a protective device I is attached to a cassette deck. Note that the protective equipment 1 is made of, for example, cardboard.

The insertion part 2 has the functions of the above-mentioned detected part and fixing part, and can be inserted into the cassette insertion hole 9 of the cassette deck 6, and is fixed by the elevator mechanism and reel shaft in the inserted state. It is thick and strong enough to operate the hook and detection section provided inside the cassette insertion hole, which will be described later.

When the insertion part 2 is inserted into the cassette insertion hole 9, the protrusion part 3 protrudes from the cassette insertion hole 9 and blocks the cassette insertion hole 9 when the detection lever of the cassette deck 6 is operated and the elevator mechanism 10 is lowered. It is configured as follows.

The button penetration part 5 is a hole provided so that the operation button 8 passes through it when the protective equipment 1 is attached to the cassette insertion hole 9 of the cassette deck 6. This prevents the protrusion 3 from being hidden, and also prevents the protrusion 3 from falling forward due to engagement with the operation button 8.

Further, on the protrusion 3, notes such as precautions during transportation and information regarding removal of the protective equipment 1 are written.

Next, the operation of attaching the protective equipment 1 to the cassette deck 6 will be explained.

FIG. 3 is a perspective view showing the elevator mechanism 10 of the cassette deck 6, and FIG. 4 is a sectional view showing the operation of installing the protective equipment 1. Note that the tape drive mechanism, heads for playback, recording, erasing, etc. are omitted.

When the elevator mechanism IO is in the raised position, the lock holding part 112 of the lever 11 fixed to the vertical movement mechanism 15 by the rotation shaft 113 is engaged with the upper end of the side plate 142, so that the elevator mechanism is in the raised position. be. Further, the lever 11 is provided with a detection section 111, and is configured so that the lever 11 is rotated by insertion of a cassette half.

When the elevator mechanism 10 is raised, the protective equipment 1
When the insertion section 2 is inserted into the cassette holding section 12 through the cassette insertion hole 9, the hook 13 moves along the guide groove 151 in the cassette insertion direction. Then, the hook 13 hits the detection section 111, and the detection section 111 moves in the cassette insertion direction. Then, the lever 11 rotates around the rotation shaft 113, the lock holding part 112 and the side plate 142 are disengaged, and the vertical movement mechanism 15 rotates downward around the fulcrum 16 by a spring (not shown). A cassette/seven tray holding section 12 is rotatably connected to the vertical movement mechanism 15 through a connecting section 17.
is raised and lowered in accordance with the rotation of the vertical movement mechanism 15. Therefore, when the vertical movement mechanism 15 rotates downward, the cassette holding part 12 descends as shown in FIG. The elevator mechanism is fixed in the lowered position by a mechanism (not shown) that fixes the vertical movement mechanism 15 to fix the half in the playing position.

Therefore, the insertion section 2 is fixed by being sandwiched between the cassette holding section and the reel shaft 141 provided on the base section 14. At this time, since the detection part 111 is pushed outward by the hook 13, the lock holding part 112 is
It is far from 2.

On the other hand, the vertical movement mechanism 15 is operated by an eject mechanism (not shown).
When the cassette holder 12 is rotated upward, the cassette holder 12 rises accordingly. When the cassette holding part 12 reaches the raised position, the hook 13 moves in the opposite direction to the cassette insertion direction by a spring (not shown), and the insertion part 2 moves to the hook 1.
3 and is ejected from the cassette insertion hole 9. Then, as the hook 13 moves, the lock holding part 112 is moved to the upper end of the side plate 142 by a spring (not shown), so that it is in the locked state again.

As described above, according to this embodiment, the insertion portion 2 of the protective equipment 1
By inserting the cassette into the cassette insertion hole 9, the elevator mechanism 10 is lowered, and the elevator mechanism 10 is fixed in the lowered position. Further, by performing an eject operation, the protective equipment 1 can be removed and becomes operable.

In this embodiment, the protector is made of cardboard, but it may also be made of a resin plate such as plastic.

Further, the protector 1 according to the present invention is not limited to this embodiment; for example, the protrusion 3 need not be shaped to cover the cassette insertion hole 9, but may be any shape that protrudes from the cassette insertion hole 9. Even in this case, since it is possible to confirm that the elevator mechanism is descending, there is no possibility of accidentally inserting a cassette during the descent.

As another embodiment of the present invention, as shown in FIG. 5, a protrusion 3 is provided extending from the end 23 of a dummy cassette 22 having a half-cassette shape.

The dummy cassette 22 has the same dimensions and shape as the cassette half, and has a protrusion 3 extending from an end 23 thereof. The operation of the elevator mechanism when the dummy cassette 22 is inserted through the insertion hole 9 of the cassette deck is the same as in the case of the protector 1 described above.

In this embodiment, the dummy cassette 22 is fitted to the reel shaft 141 as the elevator mechanism 10 descends;
Since the protective equipment cannot be removed when the elevator is lowered, it can be prevented from falling off during transportation.

〔Effect of the invention〕

As described above in detail, according to the present invention, the elevator mechanism can be easily fixed at the playback position when transporting the cassette deck.

Furthermore, since a protective device is inserted, incorrect insertion of the cassette half can be naturally prevented.
