Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a recording/reproducing apparatus having a loading mechanism for a deck section equipped with a drive mechanism for a magnetic tape for recording or reproducing.

[Background technology and its problems]

Conventionally, in a VTR, a cassette is loaded in a predetermined position by a cassette mounting mechanism, and then a magnetic tape is pulled out from the cassette by a tape loading mechanism and placed in a predetermined position.

Therefore, when performing the cassette loading operation using the front loading method,
Since the cassette loading operation and the tape loading operation cannot be carried out simultaneously, there is a drawback that the time from insertion of the cassette to transition to the recording/playback state becomes long.

In addition, if the cassette is loaded using a pocket-type cassette holder, the transition from cassette insertion to recording/playback mode can be completed in a shorter time than with the front loading method described above, but the cassette holder must be installed on the top of the recording/playback device to open and close it. Therefore, there was a drawback that objects could not be placed on top of the recording/reproducing device.

[Purpose of invention]

This idea was created in view of the problems mentioned above, and it allows for a quick transition from insertion of a cassette to the recording/playback state, as well as a loading mechanism that allows objects to be placed on top of the recording/playback device and moves the deck section. The present invention provides a recording and reproducing apparatus that employs a skating type loading mechanism so as to reduce the number of detection sections and reduce the cost by using a detection section that also controls the tape loading mechanism.

[Summary of the idea]

In order to achieve the above-mentioned purpose, this invention consists of a cassette mounting mechanism for mounting a cassette in a predetermined position, and a tape loading mechanism for pulling out and placing a magnetic tape from a cassette mounted by this cassette mounting mechanism in a predetermined position. The deck is equipped with a loading mechanism that moves the deck horizontally relative to the housing, and the tape loading mechanism is driven in synchronization, allowing for a quick transition from insertion of a cassette to the recording/playback state, as well as speed of recording and playback. Objects can be placed on the device, and the number of detection sections can be reduced by using the detection section that controls the loading mechanism and the tape loading mechanism that move the deck section, making it inexpensive. be.

In FIG. 1, 1 is a housing, and 3 is a deck part that moves horizontally with respect to the housing 1. This deck part 3 is moved by racks 2A and 2B provided on the housing 1 as shown in FIG. Configured to move. The deck portion 3 is provided with a cassette holder 4 which rotates about one end (rear) as a fulcrum, and a tape loading mechanism which will be described in detail in FIG. This cassette holder 4

In FIG. 2, 6 is a motor to which a pulley 7 is attached, and a belt 9 is stretched between the pulley 7 and the transmission pulley 8. A transmission gear 10 and a worm gear 14 are attached coaxially with the transmission pulley 8, the transmission gear 10 meshes with a reduction gear 12 attached to a shaft 11, and a drive gear 13A, which is coaxially connected to the reduction gear 12,

skates horizontally with respect to the housing 1. In FIG. 3, reference numeral 15 denotes a worm wheel gear that meshes with the worm gear 14, and directly meshes with the loading ring 17B via a loading ring 17A and an intermediate gear 16. Therefore, as shown in FIG. 2b, the motor 6
By rotating the magnetic tape T in the cassette C, the tape can be loaded by the guide rollers 18A and 18B. In addition, 19 is a drum around which the magnetic tape T attached to the deck part 3 is wound, and L is a cassette C.
It is the lid of

Next, the operation of the recording/reproducing apparatus of this invention constructed as described above will be explained.

First, insert the cassette C into the cassette holder 4 which is in the cassette insertion position of the deck part 3 which has been pulled out from the housing 1 as shown in FIG. The lid L is opened and the cassette C is placed in a predetermined position as shown in FIG. Then, a detection unit (not shown) detects the cassette C.
When it is detected that the motor 6 is attached, the motor 6 rotates, and the pulley 7→belt 9→transmission pulley 8→transmission gear 10→reduction gear 12→drive gears 13A, 13B
The rotational force is transmitted, and the deck part 3 becomes the rack 2A,
2B and is housed in the housing 1.
Further, the rotational force of the motor 6 is transmitted to the transmission pulley 8 → worm gear 14 → worm wheel gear 15, intermediate gear 16 → loading rings 17A, 17B, and guide rollers 18A, 18B pull out the magnetic tape T from the cassette C. Tape loading is performed and the magnetic tape T is wound around the drum 19. Then, the loading operation and tape loading operation of the deck section 3 are completed as shown in FIG. 2b.
When the state is reached, a detection section (not shown) detects that loading of the deck section 3 and tape loading are completed, and the motor 6 is stopped. Recording or playback can be performed in this state.

Next, when the cassette C is ejected in the state shown in FIG. 2b, the motor 6 rotates in the opposite direction to that described above, and the loading operation of the deck section 3 and the tape unloading operation are performed. Then, the deck section 3 is pulled out to the state shown in FIG. 2a, and a detection section (not shown) detects that loading and tape unloading of the deck section 3 are completed, and the motor 6 is stopped. During this operation, the magnetic tape T is wound onto the supply reel or the take-up reel, and the locking mechanism 5 is released by an appropriate mechanism shortly before the end of the loading operation of the deck section 3, and the cassette holder 4 is As shown in Figure 1, the cassette is rotated to the cassette insertion position and held by a biasing force such as a spring.

As mentioned above, in the recording and reproducing apparatus of this invention, the loading mechanism of the deck section 3 and the tape loading mechanism are synchronized by one drive mechanism and are operated simultaneously, so that the transition from the insertion of a cassette to the recording and reproducing state can be made quickly. Furthermore, since the detection section that controls the loading mechanism of the deck section 3 and the tape loading mechanism can be used in common, the number of detection sections can be reduced, and only one drive mechanism is required, resulting in low cost. Furthermore, deck part 3
Since the recording/reproducing device is accommodated in the housing 1 by skating, objects can be placed on top of the recording/reproducing device.

In addition, the cassette holder 4 is provided with a detection section for detecting the cassette C, and the transmission pulley 8 and the worm gear 1 are connected to each other.
A clutch is provided between the cassette C and the detecting section.
Preferably, the clutch is connected and tape loading is performed only when this is detected.

[Effect of idea]

As described above in detail, the recording/reproducing apparatus of this invention is configured to drive the loading mechanism of the deck section and the tape loading mechanism in synchronization, so that the transition from insertion of a cassette to the recording/reproducing state can be made quickly. Further, since the detection section for controlling the loading mechanism of the deck section and the tape loading mechanism can be used for both, the number can be reduced, resulting in low cost. Further, since the deck portion is accommodated in the housing by skating, there are advantages such as the ability to place objects on top of the recording/reproducing device.
