Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating mechanism for reliably performing an insertion operation in an automatic cassette tape loading device.

Conventionally, automatic cassette tape loading devices have been equipped with guide plates in which protrusions or rotating rollers are fixed to the left and right sides of a cassette holder that stores the cassette tape and moves together with the cassette holder, and the protrusions or rotating rollers are provided on the left and right sides of the cassette holder. The projection or rotating roller is engaged with one end of a plurality of links, the other end of the link is engaged with a rotating body, and the rotating body is separately provided as a drive. There is a method in which the cassette tape and the cassette holder are moved along the shape of the guide groove of the guide plate by rotating the tape and the cassette holder.

By the way, in order to operate the automatic cassette tape loading device, the cassette tape is inserted into the cassette holder, and when the cassette tape reaches a specified position with respect to the cassette holder, a switch is activated. However, due to variations in mechanical parts or changes in the mounting position, the switch may operate when it is not in the specified position, or may not operate even when it is in the specified position, necessitating adjustment of the switch.

Furthermore, even if the switch is adjusted, there is a drawback that erroneous operation may occur due to variations in the cassette tape.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to have an automatic cassette tape loading device always hold the cassette tape at a specified position in the cassette holder when inserting a cassette tape, and then drive the switch to operate the device. An object of the present invention is to provide an automatic cassette tape loading device provided with an operating mechanism.

In order to drive the switch without holding the cassette tape at a specified position in the cassette holder when the cassette tape is inserted into the automatic cassette tape loading apparatus, the engagement between the cassette holder of the automatic cassette tape loading apparatus and the link is controlled by the link part. The cassette tape is inserted into the cassette holder and held at the specified position by inserting a protrusion or rotating roller fixed to the cassette holder into the elongated hole and holding it at the other end of the elongated hole with a spring. Then, by further pushing the cassette tape, the cassette holder holding the cassette tape can move in the direction of the elongated hole against the spring of the link, thereby driving the switch.

FIG. 1 shows a schematic view of an automatic cassette tape loading device which is an embodiment of the present invention, and FIG. 2 shows an enlarged view of the main parts of the operating mechanism.

In the figure, 2 is a motor which is a driving source, and 3 is a gear for transmitting power from the motor 2 through a gear 4 to rotate a driving gear 5. Reference numeral 6 indicates a pin provided on the lever 7 to form a link and is engaged with the drive gear 5. Reference numeral 8 indicates a lever engaged by a pin 9 to form the link together with the lever 7.
Reference numeral 10 designates a rotating roller which is fixed to the cassette holder 11 and is engaged with an elongated hole 18 of a lever 8 forming a link and held at its end by a spring 15. 12 is a guide pin fixed to the cassette holder 11;
3 is a projection, and 14 is a spring that holds the cassette tape 16. 17 is a switch for driving during insertion. Reference numeral 20 denotes a guide groove 2 for controlling the operation of the rotating roller 10 and guide pin 12 fixed to the cassette holder 11.
This is a guide board equipped with numbers 1 and 22. Reference numeral 30 denotes a connecting shaft that is provided with gears 4 on the left and right sides and is used to interlock the left and right drive gears 5.

Next, we will explain the operation.

By inserting the cassette tape 16 into the cassette holder 11 to the position where it is stopped by the protrusion 13 of the cassette holder 11, the cassette tape 16 is held at the specified position of the cassette holder 11 by the cassette presser spring. become something that In this state, the motor 2, which is the drive source of the automatic mounting device, is not operated at all.

Therefore, by further pushing the cassette tape 16 while it is held in the specified position of the cassette holder 11, the spring 15 can be removed from the relationship between the elongated hole 18 of the link lever 8 and the spring 15.
The elongated hole 18 can be moved against the By this operation, the switch 17 can be actuated directly by the cassette tape 16 or indirectly through other parts, and the motor 2, which is the drive source, is operated for the first time. The cassette holder 11 is moved along the guide grooves 21 and 22 via the link levers 7 and 8 by the rotation of the drive gear 5 by the motor 2,
The cassette tape 16 is attached to an internal mechanism (not shown).

That is, the switch 17 is actuated by holding the cassette tape 16 at a specified position on the cassette holder 11 and then pushing it further in that state, so that the cassette tape 16 can always be held at the specified position on the cassette holder 11. .

As described above, by providing the operating mechanism of the automatic cassette tape loading device of the present invention, the cassette tape can be always loaded by holding the cassette tape at a specified position in the cassette holder and then pushing the cassette tape further. We decided to activate the automatic loading device by activating the switch with the tape and cassette holder in the specified position, so if the switch was activated when the cassette tape was inserted into the specified position of the cassette holder, as before. Therefore, it is possible to provide an automatic cassette tape loading device that is highly reliable and safe in operation and eliminates the need for adjustment.
