Abstract

PURPOSE:To exactly fix a cartridge, and to prevent it from being flawed and being broken down, by fixing mechanically the cartridge by a cartridge stopper. CONSTITUTION:When a hand mechanism 14 advances in order to house a cartridge 2 into a case 1, a projecting part 17 of a hand 16 presses a driving pin 12 of a lever 4. Therefore, the lever 4 is guided by a guide groove 6 and guide pins 7, 8 and goes straight on until the end point of a linear part 6a of the guide groove 6 and the guide pin 8 are brought into contact with each other, and thereafter, the lever 4 rotates centering around the end point and the guide pin 7. Simultaneously, its tip part 4a abuts on a detaining piece 3a of a cartridge stopper 3 and pushes out the cartridge stopper 3 to the outside. In this case, a pin 9 for supporting a spring 11 goes over a dead point, therefore, the lever 4 is held in a state that the cartridge stopper 3 remains pushed out to the outside. In this regard, when the hand 16 moves backward, the projecting part 17 pushes a reset pin 13, therefore, the lever rotates in the reverse direction and reset by an elastic force of the spring 11.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cartridge transport device in an apparatus using a magnetic tape or the like having seven cartridges.

[Prior Art] Conventionally, as this type of cartridge transport device, there is one shown in FIG. 4, for example.

This cartridge transport device includes a hunt mechanism 23 for holding a cartridge 22 in a case 21 and a case 22.
The latch spring 24 is attached to the latch spring 24.

In this device, the case 21 is
Push the cartridge 22 into the At this time, the hand mechanism 23
The cartridge 22 is caught between the latch flaps 24 by the pushing force, and the cartridge 22 is completely stored.

[Problems to be Solved] The above-mentioned conventional cartridge transport device has the drawback that the fixing of the cartridge 22 to the case 21 relies on the frictional force of the latch spring 24, which makes the fixing force unstable and cannot securely hold it. There is.

Also, when the force of the latch spring 24 is increased, the hand mechanism 23
It is also necessary to increase the driving force of the transfer device, which has the disadvantage that the transfer device itself becomes larger and more complicated.

[Means for Solving Problems] A cartridge transporting device of the present invention which solves the above-mentioned conventional problems includes: a case for storing a cartridge; a cartridge stopper for preventing the cartridge stored in the case from jumping out; A hand mechanism having a hand for holding and transporting a cartridge, a hand frame provided with a rail for moving the hand mechanism back and forth, and a guide provided on the hand frame;
A lever guided by the guide to release the cartridge stopper 11cr when the Off-cartridge and the cartridge stopper 111f come into contact with each other when the cartridge is taken in and out; and a lever between this lever and the hand frame. The cartridge stopper is configured to include a spring for maintaining the position of the lever when the provided cartridge stopper is released.

[Embodiment 1] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing a cartridge conveying device according to an embodiment of the present invention, FIG. 2 is a top view showing when the cartridge is taken in and out of the device, and FIG. 3 is taken along line A-A in FIG. 1. FIG.

In the figure, reference numeral 1 denotes a case in which a large number of cartridges 2 are housed vertically, and a cartridge stopper 3 for holding the cartridges 2 is attached to one side surface of the case 1. This cartridge stopper 3 is formed of an elastic plate-like body, and a locking piece 3a is provided at the tip thereof, and this locking piece 3a is pressed against the tip 4b of a diagonal piece 4a provided at the tip of the lever 4. It is designed to be canceled by being released. The lever 4 is provided at the tip of the side plate 5a of the L-shaped hunt frame 5. The lever 4 is formed with a guide groove 6 having a straight portion 6a and a circular arc portion 6b continuous with the straight portion 6a. Guide pins 7.8 are provided on the hand frame 5 in correspondence with the guide grooves 6 of the lever 4, and the lever 4 is slid and guided along these guide pins 7.8. .

Each support bin 9 is provided between the lever 4 and the hand frame 5.
．． A spring 11 is tensioned at 10, and exerts a return force on the lever 4 in the direction indicated by arrow A in the figure. A driving pin 12 is provided at the lower end of the straight portion 6a of the guide groove 6 in the lever 4, and a return pin 13 is provided at the rear of the guide groove 6.

A hunt mechanism 14 is provided within the hand frame 5 so as to be movable backward along a pair of rails 15a, 15b. The hand mechanism 14 has a hand 16 attached to the front portion thereof that hits a holding portion 16a, and this hand 16 holds and conveys the cartridge 2. this hand 1
A protrusion 17 that abuts against the drive pin 12 or return pin 13 of the lever 4 is recessed at the tip of the side of the lever 6 facing the lever 4 .

Next, the operation of the cartridge transport device having the above configuration will be explained. That is, when the hand mechanism 14 is advanced 11" in order to store the cartridge 2 in the case 1, the protrusion 17 of the hand 16 moves into the drive bin 12 of the lever 4 as shown in FIG.
to impose. Therefore, the lever 4 is guided by the guide groove 6 and the guide bin 7°8, moves straight until the end point of the linear portion 6a of the guide groove 6 contacts the guide bin 8, and then the lever 4 moves around the end point and the guide bin 7. At the same time, the tip 4a of the cartridge rotates, and at the same time, its tip 4a comes into contact with the two pieces 3a of the retainer 11 of the cartridge stopper 3, pushing the cartridge stopper 3 outward. At this time, since the pin 9 supporting the spring 11 passes the put point, the lever 4 is moved to the cartridge stopper 3.
is held while being pushed out.

In addition, the cartridge 2 is stored in the case 1, and the hand 16 is
When the lever moves backward, the protrusion 17 pushes the return pin 13, so the lever 4 rotates in the opposite direction to the above, and the spring spring 11
It returns due to the elastic force of

[Effects of the Invention] As explained above, the cartridge conveying device of the present invention has the following effects:
Since the cartridge is mechanically fixed by the cartridge stopper, the cartridge can be fixed securely and the cartridge will not be damaged or destroyed.

Furthermore, since the lever drives the cartridge stopper when the cartridge is stored in and taken out of the case, the cartridge stopper does not come into contact with the cartridge, thereby preventing the cartridge from being scratched or worn out.
