In addition, the base 100 is provided with a fixing lever 153 for selectively engaging and fixing the position of the hook protrusion 250 of the slider 200 to be described later. The fixing lever 153 is provided with an elastic piece 156 that applies an elastic bias to protrude the inserted cartridge 10 to the outside. The fixing lever 153 is elastically biased in the direction to be hooked to the hook projection 250 by the torsion spring 159 installed on the hinge shaft 151. The fixed lever 153 is released from the hook protrusion 250 as the cartridge 10 to be inserted rotates the elastic piece 156.

The slider 200 has a lifting bracket 220 to which the lifting protrusion 320 of the holder 300 is fitted. The lifting bracket 220 is provided with a bracket rail 321 provided in parallel with the surface of the slider and a bracket groove 322 having an ohmic width recessed downward from an end of the bracket rail. In addition, a spring 230 is provided at a predetermined portion of the base 100 and a predetermined portion of the slider 200. The spring 230 exerts an elastic bias on the slider 200 against the cartridge insertion. The slider 200 is further provided with a hook protrusion 250 that is selectively engaged with the fixed lever 153.

A guide protrusion 310 fitted into the guide groove 110 and a lifting protrusion 320 formed at points spaced apart at predetermined intervals from both sides of the guide protrusion 310 are formed on sidewalls of the holder 300.

In addition, a clamping means 330 for clamping the disk 11 of the cartridge 10 is provided on the holder 300. The clamping means 330 is provided with a clamper 331 for clamping the disk 11 on one side thereof, and a contact portion 332 corresponding to the stopper 130 is formed on the other side thereof. An approximately center portion of the clamping means 330 is levered to the lever engagement position 335 of the holder 300. Accordingly, when the contact portion 332 is pressed against the stopper 130, the lever 331 moves downward with respect to the lever engagement position 335, and the clamper 331 moves downward and the clamper 331 can clamp the disk 11. Can be. In addition, at a position close to the lever engagement position 335 of the clamping means, an end is supported on a chassis (not shown) of the upper deck, and an elastic means 333 is installed to elastically bias the holder 300 downward.

In addition, an upper portion of the holder 300 is provided with an opening for opening the cover member 12 of the cartridge to be inserted. The opening part includes a guide slot 340 formed on the upper surface of the holder 300, a guide bar 342 for opening the cover member 12 of the cartridge while being guided along the guide slot 340, and a guide bar 342. It consists of a torsion spring 344 which elastically biases the to an initial position direction. The guide bar 342 is initially located in the shear projection 12a of the cover member. The guide hole starts at an initial position in the cartridge insertion direction and extends to a position corresponding to the clamper 331, and extends from the first guide hole 340a to the cartridge insertion complete position. It consists of a second guide long hole (340b).

The operation of the disc cartridge deck having such a structure will be described.

When the disc 10 in which the disc is embedded is not inserted into the deck inlet, the holder 300 is raised above the side walls 101 and 102 of the base 100. That is, the fixed lever 153 rotated by the torsion spring 159 is held on the hook protrusion 250 of the holder, and this is the lifting protrusion 310 and the lifting bracket 200 of the holder 300. Since the bracket rail 321 of FIG. 3 corresponds to the bracket rail 321, the holder 300 maintains a raised state with respect to the side walls 101 and 102.

Next, when the cartridge 10 is inserted into the deck inlet, as shown in FIG. 2, the guide bar 342 located at the end of the first guide hole 340a is connected to the front end projection 12a of the cover member 12. Walks At this time, as shown in FIG. 3, the holder 300 maintains an elevated state with respect to the base 100. Since the holder is raised, as shown in FIG. 4, the contact portion 332 of the clamping means 330 is not pressed against the stopper 130 of the base 100, and the clamper 331 is downward. Since it is not in the lowered state, a space for inserting the cartridge 10 into the holder 300 is secured.

Next, when the cartridge 10 is further inserted, as shown in FIG. 5, the guide bar 342 is moved along the first guide long hole 340a to open the cover member 12 so as to open the disk 11 outside. Expose

When the cartridge 10 is further inserted, the guide bar 342 is transported on the second guide slot 340b and the cover member 12 is kept open.

When the cartridge 10 is fully inserted as shown in 6, the front end of the cartridge 10 pushes the elastic piece 156 in the insertion direction. Accordingly, the fixing lever 153 connected to the elastic piece 156 is out of the hook protrusion 250. At this time, the spring 230 provided in the predetermined portion of the base 100 and the predetermined portion of the slider 200 transfers the slider 200 in the opposite direction to the insertion, and thus, the lifting protrusion 320 of the holder 300. As shown in FIG. 7, the height of the bracket rail 321 of the elevating bracket 220 is dropped to the height of the bracket groove 322 is located, as a result, the holder 300 is lowered. In addition, as the slider 200 is transferred in the direction opposite to the insertion, the switch protrusion 200a protrudes from the deck inlet.

When the holder 300 is lowered, as shown in FIG. 8, the contact portion 332 of the clamping means 330 is pressed against the stopper 130 of the base 100. Then, the clamping means 330 is a lever movement around the lever engagement position 335 to transfer the clamper 331 downward. Accordingly, the disk seated on the turntable 338 which rotates the disk 11 is clamped.

Press the switch protrusion 200a to take out the cartridge 10 from the deck. Then, the slider 200 is transported in the insertion direction while conveying the lifting bracket 220 together. Accordingly, the lifting projection 320 located in the bracket groove 322 is moved to the bracket rail 321 to raise the holder 320 as a result. Then, the clamping means 330 levered to the lever engagement position 355 rises together, and the clamper 311 releases the clamping of the disk 11. Then, the elastic piece 156 applies an elastic bias in the direction opposite to the insertion of the front end portion of the cartridge 10, the instant the cartridge 10 is projected from the deck inlet. In this process, the fixing lever 153 is rotated and the hook protrusion 250 is engaged, and the slider 200 is no longer moved. This returns the initial state before the cartridge is inserted.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. .

As described above, according to the disc cartridge deck of the present invention, when the cartridge is inserted into the holder, the guide bar is first hung on the shear projection, and in this state, the guide bar, which is conveyed along the guide hole as the cartridge is inserted, passes through the clamper. The cover member is completely opened to expose the disc to the outside, and the cartridge is fully inserted while maintaining this state. Therefore, since the disk is first opened in the cartridge, the space between the cartridge body and the disk can be utilized, thereby making it possible to realize slimming of the manufactured product.
