  The present invention relates to a flap member for opening and closing a cartridge insertion / extraction opening that is used to close an insertion / extraction opening for inserting and discharging a cartridge and is pushed open by the cartridge when the cartridge is inserted or discharged.

  2. Description of the Related Art Conventionally, in an audio system having a function of reproducing or recording an MD (mini disc), an MD cartridge is loaded by inserting it from an insertion / extraction opening provided on a design panel surface. The insertion / extraction port is provided with an MD flap for closing the insertion / extraction port for the purpose of dust prevention or the like (see Patent Document 1).

  FIG. 3 is a perspective view showing a state when the MD cartridge is discharged in such a conventional audio system. In the figure, 31 is an MD flap, 32 is an outer rib provided on the outer surface of the MD flap 31, 33 is an inner rib provided on the inner surface of the MD flap 31, 2 is an MD cartridge, and 2e is a shutter of the MD cartridge. , 37 are arrows indicating the ejection direction of the MD cartridge 2.

  The MD flap 31 is rotatably provided at an insertion / extraction port on a design panel surface (not shown), and normally closes the insertion / extraction port. When the MD cartridge 2 is inserted or ejected from the insertion / extraction opening toward the loading position in the system, the MD flap 31 is pushed open from the outside or the inside by the MD cartridge 2.

  Two outer ribs 32 are provided near both ends of the MD flap 31. These outer ribs 32 are in contact with the MD cartridge 2 at two points when the MD cartridge 2 is inserted, and have a role of relieving friction between the MD flap 31 and the MD cartridge 2. Further, when only the outer rib 32 comes into contact with the MD cartridge 2, the MD cartridge 2 is also prevented from being damaged.

  The inner rib 33 prevents the shutter 2e and the MD flap 31 from interfering with each other by making contact with the MD cartridge 2 at a point other than the shutter 2e when the MD cartridge 2 is ejected. It plays a role of reducing friction between the cartridge 2 and the MD flap 31.

  FIG. 4 shows the state of FIG. 3 viewed from the direction of the arrow 38. As shown in the figure, when the cartridge 2 is inserted, the inner rib 33 comes into contact with the surface of the MD cartridge 2 at one point, and acts so that the MD flap 31 is separated from the surface of the MD cartridge 2. As a result, friction between the MD cartridge 2 and the MD flap 31 is reduced.

  However, according to the above-described prior art, the inner rib 33 provided at the center inside the MD flap 31 may damage the case of the MD cartridge 2 while the ejection of the MD cartridge 2 is repeated several times. . In recent years, the decoration of MD cartridges has also been diversified, and the decoration of the case surface with a beautiful pattern has become conspicuous. Therefore, if the decoration is damaged, it is particularly noticeable.

  An object of the present invention is to provide a technique for preventing the surface of a cartridge from being scratched by a flap-like member as much as possible when the cartridge is inserted or ejected from an insertion / ejection opening in view of the problems of the conventional technology. There is.

  The flap member for opening and closing the cartridge insertion / extraction opening according to the present invention is provided rotatably at the insertion / extraction opening for inserting and discharging the cartridge, and closes the insertion / extraction opening at times other than when the cartridge is inserted and discharged. When the cartridge is inserted and ejected, it is pushed open by the cartridge. In order to achieve the above object, the flap-shaped member is a slide that keeps the flap-shaped member in an open state by sliding with one side along the insertion or discharge direction on the cartridge when the cartridge is inserted or discharged. It comprises the part.

  Here, examples of the cartridge include an MD cartridge, a cassette tape, and a DVD-RAM disk with a cartridge. As the sliding portion, for example, one having one side along the insertion or discharge direction on the cartridge and a sliding surface that slides at almost one point is applicable. The sliding surface may be curved.

  In this configuration, when the cartridge passes through the insertion / ejection opening when the cartridge is inserted or ejected, the sliding portion of the flap-shaped member pushed open by the cartridge slides with one side along the insertion or ejection direction on the cartridge. Thereby, the flap-shaped member is maintained in the open state. That is, since the flap-like member is kept open while this sliding is performed, it is not necessary to make contact with the cartridge in other parts than the sliding part. Therefore, it is possible to prevent the main surface on the cartridge from being damaged by the flap-like member. Although there may be a scratch on the sliding portion of the flap-shaped member and the side of the cartridge that slides, the size of the scratch is small and does not stand out so much.

  In the first invention, the flap member for opening and closing the cartridge insertion / extraction port according to the second invention is configured such that the cartridge and the flap member are connected to the sliding portion and the sliding member when sliding on one side of the cartridge with the sliding portion. Only one side on the cartridge is in contact with each other.

  The flap member for opening and closing the cartridge insertion / ejection port according to the third aspect of the invention is the first or second aspect of the invention, wherein the sliding portion is pushed by a corner portion of one end of the one side on the cartridge when the cartridge is inserted or ejected. The flap-shaped member is changed from the closed state to the open state by sliding with the corner portion.

  The flap member for opening and closing the cartridge insertion / extraction port according to the fourth invention is the cartridge according to any one of the first to third inventions, wherein the cartridge has a substantially rectangular parallelepiped shape, and the insertion / extraction port extends along the one side of the cartridge. The flap-shaped member is composed of a substantially rectangular plate-shaped member that has a shape and size adapted to be inserted or ejected in a direction, is long in the axial direction of its rotation, and is adapted to close the insertion / extraction port. It is characterized by.

  The flap member for opening and closing the cartridge insertion / ejection port according to the fifth invention is the first to fourth inventions, wherein the flap member is orthogonal to the axis of rotation of the flap member and parallel to the plate surface of the flap member. It is characterized by having, as a sliding portion, an inclined surface that is parallel to a straight line and has a height from the plate surface that is higher near the end of the flap-shaped member.

  The flap member for opening and closing the cartridge insertion / ejection port according to the sixth invention is the MD cartridge according to any one of the first to fifth inventions, and the sliding part is a shutter of the MD cartridge inserted or ejected. It is provided on the non-contact side.

  According to the present invention, it is possible to prevent the surface of the cartridge from being damaged by sliding with the flap-shaped member when the cartridge is inserted or ejected.

  FIG. 1 is a perspective view showing an MD flap portion in an audio system according to an embodiment of the present invention, and FIG. 2 is a front view showing a part of FIG. In these drawings, reference numeral 1 denotes an MD flap for closing an insertion / extraction opening provided on a panel surface of an audio system (not shown), and 2 denotes an MD cartridge inserted and discharged through the insertion / extraction opening. However, in the figure, the state when the MD cartridge 2 is ejected in the direction of arrow B is shown.

  The MD flap 1 is composed of a rectangular plate-like member that is adapted to the shape of the insertion / extraction port. The MD flap 1 is provided with a rotating shaft 3 at both ends, two ribs 4 near both ends of the outer surface, and an inclined surface 5 at one end of the inner surface. The MD cartridge 2 has a substantially rectangular parallelepiped shape, and the insertion / extraction opening has a shape and size suitable for the insertion of the MD cartridge 2.

  The rotating shaft 3 extends in the direction of the long side 1a from both end portions of one long side 1a of the MD flap 1. The MD flap 1 is supported so as to be able to rotate around the long side 1 a via the rotation shaft 3, and closes or opens the insertion / extraction port according to the rotation position. An urging force is applied to the MD flap 1 in the rotating direction via the rotating shaft 3, and the urging force is directed to a position where the MD flap 1 just closes the insertion / extraction port. That is, the MD flap 1 closes the insertion / extraction port by an urging force except when the MD cartridge 2 passes through the insertion / extraction port, but the MD cartridge 2 resists the urging force when the MD cartridge 2 is inserted and discharged. It can be pushed open.

  Each rib 4 is provided in parallel to the short side of the MD flap 1. When the MD cartridge 2 is inserted, the two ribs 4 sequentially come into contact with the end surface 2c on the insertion direction side of the MD cartridge 2 and the surface 2d on the rotation shaft 3 side at two points, whereby the MD flap 1 and the MD cartridge 2 are contacted. It has a role to relieve the friction with. For this purpose, the contact portion of the rib 4 with respect to the MD cartridge 2 is a rounded surface.

  The inclined surface 5 is provided inside the end of the MD flap 1 opposite to the shutter 2e of the MD cartridge 2 that passes through the insertion / ejection port. The inclined surface 5 is parallel to a straight line that is orthogonal to the rotation shaft 3 and parallel to the plate surface of the MD flap 1, and the height from the plate surface is higher as the portion is closer to the short side of the MD flap 1. Yes. Therefore, when the MD cartridge 2 is ejected, when the inclined surface 5 is pushed by the corner portion 2b of one end 2a along the ejection direction on the MD cartridge 2, the MD flap 1 is shown in the closed state in FIG. 1 or FIG. It becomes such an open state. Thereby, the inclined surface 5 becomes substantially parallel to the side 2a along the discharge direction and contacts at one point, and then slides with the side 2a to maintain the MD flap 1 in the open state.

  In this configuration, when the MD cartridge 2 loaded in the audio system is ejected from the insertion / ejection opening by the audio system, the MD cartridge 2 is delivered in the ejection direction indicated by the arrow B. When the end surface 2 f on the ejection direction side of the MD cartridge 2 reaches the position of the MD flap 1 that closes the insertion / extraction port, the corner portion 2 b of the MD cartridge 2 contacts the inclined surface 5 of the MD flap 1. As a result, the corner portion 2b presses the inclined surface 5, and the MD flap 1 starts to rotate.

  When the MD cartridge 2 is further fed in the discharge direction, the corner portion 2b slides on the inclined surface 5 while pushing the inclined surface 5, whereby the MD flap 1 is pushed open. When the end surface 2f of the MD cartridge 2 reaches the position of the long side 1b opposite to the rotation axis of the MD flap 1, the MD flap 1 is in the most open state. At this time, the inclined surface 5 is in contact with and substantially parallel to the side 2 a of the MD cartridge 2.

  Thereafter, the MD cartridge 2 is further delivered, and when the position shown in FIG. 1 is reached, the delivery of the MD cartridge 2 is stopped. During this time, the inclined surface 5 maintains the open state of the MD flap 1 by sliding in a state substantially parallel to the side 2 a of the MD cartridge 2. Thereafter, the MD cartridge 2 is pulled out by the user, but the open state of the MD flap 1 is similarly maintained by the inclined surface 5 until the end surface 2 c of the MD cartridge 2 reaches the position of the long side 1 b of the MD flap 1. Is done. When the end surface 2c of the MD cartridge 2 exceeds the position of the long side 1b of the MD flap 1, the MD flap 1 returns to the neutral position that closes the insertion / extraction port by the urging force. Thereby, the ejection of the MD cartridge 2 is completed.

  According to this embodiment, the inclined surface 5 is provided on the MD flap 1, and when the MD cartridge 2 is ejected, the inclined surface 5 comes into contact with the corner portion 2b and the side 2a of the MD cartridge so that the MD flap 1 is opened. Therefore, it is possible to prevent the surface of the MD cartridge 2 from being damaged due to the contact between the MD cartridge 2 and the MD flap 1 when the MD cartridge 2 is discharged.

  Note that the present invention is not limited to the above-described embodiment, and can be implemented with appropriate modifications. For example, in the above description, the inclined surface 5 is provided on the inner side of the MD flap 1, but in addition to this, a similar inclined surface may be provided on the outer side of the MD flap 1. This inclined surface can be provided so as to be symmetric with the inclined surface 5, for example, with the MD flap 1 as a symmetrical surface. According to this, even when the MD cartridge 2 is inserted, it is possible to prevent the surface of the MD cartridge 2 from being damaged by the same action.

  In the above description, the MD flap provided in the insertion / extraction port for the MD cartridge has been described. However, the present invention is not limited to this, and the flap provided in the insertion / extraction port for a cassette tape, a floppy disk or other media. Can also be applied.
