In the second embodiment, reference numerals 201 and 202 are attached to the gears denoted by reference numeral 20 in the first embodiment and will be described in detail below.

  In the recording / reproducing apparatus 1 according to the second embodiment, the lever member 13 is disposed in the vicinity of the gear 202, and the gear 202 and the gear 201 to which the pulley 21 is attached are engaged with each other so as to be interlocked with each other. In addition, an engaging protrusion 100 is formed on one end 13A of the lever member 13.

  The gear 202 is formed with a first cam groove 101 extending 360 degrees in the circumferential direction, and an arcuate second cam groove 102 further inside the first cam groove 101. Is formed. Note that the engaging projection 100 of the lever member 13 is fitted into the groove portion 103 composed of the first cam groove 101 and the second cam groove 102, and the engaging protrusion 100 is guided along the groove portion 103. It has become so.

  Reference numeral 105 denotes a lever whose other end 105 </ b> B is pivotally supported on the main body frame 12. The other end 105 </ b> B located on the opposite side of the one end 105 </ b> A of the lever 105 serves as a rotation fulcrum of the lever 105.

  The one end 105A of the lever 105 and the one end 13A of the lever member 13 are constructed by a flexible resin member 106 integral with the lever 105, and when the gear 201 is rotated counterclockwise, etc. Further, the engaging protrusion 100 of the lever member 13 guided in the first cam groove 101 is urged by the resin member 106 so as to be guided in the second cam groove 102. The operation of the lever 105 is such that the one end 105A is moved by the operation of the cam plate 24. Therefore, the lever 105 is rotated using the other end 105B as a rotation fulcrum, and the resin member 106 is also rotated accordingly.

  Next, regarding the operation sequence in which the tray 10 of the recording / reproducing apparatus 1 according to the second embodiment is carried out from the carry-in state in the cabinet 2 to the outside of the cabinet 2, (a) to (d) in FIG. Will be described in the order. 6A shows a state in which the tray closes the opening, and the cam plate 24 is arranged on the rightmost side of the main body frame 12 (the state shown in FIG. 5). From such a state, when the user performs a predetermined operation for carrying out the tray 10 to place a disk on the tray 10, the gear 201 is rotated via the pulley 21 by the driving force of the motor 11. The gear 202 engaged with the gear 201 is rotated clockwise, and the engagement protrusion 100 fitted in the second cam groove 102 moves along the second cam groove 102, and this movement In conjunction with this, the lever member 13 is rotated counterclockwise (FIG. 6B). When the gear 202 is continuously rotated clockwise, as shown in FIG. 6C, the lever member 13 is further rotated counterclockwise. When the gear 202 is further rotated clockwise, the engagement protrusion 100 is moved to a point C where the first cam groove 101 and the second cam groove 102 intersect, and the resin member 106 is moved in a direction opposite to the gear 201. When the gear 201 is further rotated, the traverse unit operates in conjunction with the movement of the cam plate 24 in the middle of movement in conjunction with the gear 202 rotating in the clockwise direction. 23 descends. In addition, after the other end 13B of the lever member 13 pushes and opens the open / close door 4, the tray 10 is engaged with the gear 202 and the rack 10B formed on the tray 10, and is opened in conjunction with the rotation operation of the motor 11. Unloaded from part 3. As a result, the tray 10 carried out from the opening 3 is opened before contacting the opening / closing door 4 biased to a position where the opening 3 is closed by the coil spring 5, so that the tray 10 can be opened and closed as in the prior art. It is possible to prevent the generation of noise due to contact with the door. Accordingly, the lever member 13 is rotated in conjunction with the rotation operation of the gear 202 constituting the transmission mechanism 22, and the other end 13B of the lever member 13 can push the opening / closing door 4 open by this rotation operation. It becomes.

  According to the second embodiment, among the members that are driven in conjunction with the driving force of the motor 11, a structure in which the lever member 13 is directly attached to the gear 202 that meshes with the rack 10B of the tray 10 is particularly preferable. The reason is that the gear 202 is configured to directly open and close the tray as compared with the pulley 21 of the same transmission mechanism 22, so that the torque is amplified with a small number of rotations. Since the cam plate 24 is operated, the cam plate is operated before the cam plate is operated, so that the opening / closing door 4 when the tray 10 is conveyed can be opened at an earlier timing than in the first embodiment. Is one of the reasons.
