Description

  The present invention relates to a lid locking device for a card insertion slot into which a card such as a PC card is inserted, and more particularly to a lid locking device that can lock a lid other than a card so that the lid does not open.

  Information processing devices such as personal computers and various electronic devices are provided with a card insertion slot for inserting a PC card or other card. When a PC card or the like is inserted into the slot from the card insertion slot, the card is inserted through the connector in the slot. Many of them are electrically connected and can be used immediately. A lid is usually attached to the card insertion slot to prevent entry of dust and the like.

  As a lid locking device attached to such a card insertion slot, when a PC card is inserted into the slot from the card insertion slot in the functional state when the personal computer is turned on, the solenoid of the locking device is detected by detecting the cover lid state. A card lock device is known in which a lock pin protrudes from a solenoid and engages with a pin hole of a lid member so that the lid member is locked and a card cannot be pulled out from an insertion slot (patent) Reference 1).

  Also, after inserting the memory card along the guide frame of the guide part from the card insertion slot of the device body, the card cover is pushed in a horizontal state, and the card cover is held in a closed state by using a lock lever. A device that prevents the card from being detached from the memory card connector is also known (Patent Document 2).

Furthermore, when the IC card cover is attached to the main body of the apparatus and the lock switch is slid to the LOCK side, the knob is caught on the IC card cover and the IC card cover is closed and fixed. At this time, the lock switch is turned on. There is also known a lock device in which the IC card cannot be removed, and when the lock switch is slid to the UNLOCK side, the lock switch is turned off so that the IC card can be removed (Patent Document 3).

Then, when the card is inserted while simultaneously pushing the projections of the pair of left and right unlocking members protruding forward from the openings on both sides of the lid at the tip of the card, the pair of left and right locking members and the engaged portion at the upper end of the lid Since the engagement is released and the lid is automatically unlocked, the card can be inserted. On the other hand, even if a coin other than a card is about to enter from the card insertion slot, the coin cannot be unlocked by pressing the protrusions of the pair of left and right unlocking members at the same time, thereby preventing coins from being mixed can do.

  In the lid locking device of the present invention, the locking member is pivotally supported at the rear end thereof so as to be pivotable up and down, and an engaging claw portion that engages with the engaged portion at the upper end of the lid from above is formed at the tip of the locking member. The lock release member pushes up the lock member and pivots upward to easily disengage the engagement claw at the tip of the lock member and the engaged portion at the top of the lid. When the body can be unlocked and cannot be pushed up by the unlocking member, the locking member rotates downward by its own weight, and the engaging claw at the tip engages with the engaged portion at the upper end of the lid from above. And the lid can be locked.

  In the lid locking device of the present invention, when the upper end of the unlocking member is pivotally supported by the axis of the lid, the lid is automatically unlocked as described above. When the card is inserted into the slot from the card insertion slot, the unlocking member rotates backward with the lid about the axis of the lid and escapes, thus preventing the unlocking member from interfering with the card insertion. Can do.

  A part of the back surface of the unlocking member is formed on a cam surface that pushes the protrusion of the unlocking member and pivots the locking member upward when the unlocking member is rotated backward. Then, the lock member can be smoothly rotated upward and downward by the cam surface, so that the unlocking of the lid and the locking of the lid can be reliably performed.

The body 1 protrudes left and right from the upper end portions on both sides. The shaft 1a is not limited to a metal one as in this embodiment. For example, the shaft 1a is formed integrally with the same synthetic resin as the lid 1 so as to protrude from the upper ends of both side surfaces of the lid 1 to the left and right. It may be a thing.

  The lid 1 is disposed on the rear side of the card insertion slot 4, and the shafts 1 a protruding left and right from the upper end portions on both sides of the lid 1 are held by bearing portions (not shown) formed on the left and right sides of the card insertion slot 4. As a result, the shaft 1a is pivotally mounted in the opening / closing direction (front-rear direction).

  A pair of left and right openings 1b and 1b for projecting a protrusion 3a of an unlocking member 3 (to be described later) forward are formed on the left and right sides of the lid 1, and the upper ends of the left and right sides of the lid 1 In the figure, engaged portions 1c and 1c for engaging engagement claws 2a of the lock member 2 described later are provided.

  The lock members 2 and 2 are disposed above both sides of the lid body, and are supported by a bearing portion (not shown) at the rear end shafts 2b and 2b so as to be pivotable up and down. Engagement claw portions 2a and 2a that are engaged with the engaged portions 1c and 1c at the upper end of the lid 1 from above are projected downward at the front ends of the lock members 2 and 2 so that the card is not inserted. As shown in FIGS. 3 and 5A, the engaging claw portion 2a is engaged with the engaged portion 1c, and the lid body 1 is prevented from rotating in the opening direction (rearward). The lid 1 can be locked. When the locking members 2 and 2 are rotated upward about the rear end shafts 2b and 2b, the engaging claws 2a and 2a are disengaged from the engaged portions 1c and 1c, and the lid body 1 is released, and when the lock members 2 and 2 are rotated downward from this state, the engaging claws 2a and 2a are engaged with the engaged portions 1c and 1c from above, and the lid body 1 is again engaged. It is supposed to be locked.

  In addition, convex portions 2c and 2c that come into contact with a cam surface 3b of the unlocking member 3 to be described later are protruded downward at an intermediate portion of the locking members 2 and 2, and at the tips of the convex portions 2c and 2c, respectively. The front and rear edge portions are rounded so that they can slide smoothly with the cam surface 3b.

  As shown in FIG. 4, the unlocking members 3 and 3 are formed with protrusions 3a and 3a protruding forward from the lower end, and bearing holes 3c and 3c are formed outside the upper end. 1 and 2 and 3, the unlocking members 3 and 3 are configured so that the projections 3a and 3a protrude forward from the left and right openings 1b and 1b of the lid 1, respectively. The bearing holes 3c and 3c are rotatably attached by passing them through both end portions of the shaft 1a of the lid 1.

  As shown in FIGS. 3 and 4, a part of the back surface of the unlocking members 3 and 3 is formed on a cam surface 3 b that is rounded and bends in a substantially “<” shape, and this cam surface 3 b is a lock member. 2 is in contact with the convex portion 2c obliquely from below.

  The operation of the lid locking device configured as described above will be described with reference to FIG.

  First, before the card C is inserted, as shown in FIG. 5A, the lid 1 is closed in a state of hanging from the shaft 1a, and the engaging claw portion 2a of the lock member 2 is closed by the lid 1. The lid 1 is engaged with the engaged portion 1c at the upper end from above, and the lid 1 is rotated in the opening direction (backward) and is not opened. In this state, the protrusion 3 a of the lock release member 3 protrudes forward from the opening of the lid 1, and the cam surface 3 b of the lock release member 3 is in contact with the convex portion 2 c of the lock member 2 from obliquely below.

  When the card C is to be inserted into the card insertion slot 4 as shown in FIG. 5B, the protrusion 3a of the unlocking member 3 is pushed in at the tip of the card C, and the unlocking member 3 moves the shaft 1a. The protrusion 2c of the lock member 2 is pushed up by the cam surface 3b of the lock release member 3, and the lock member 2 is rotated upward about the shaft 2b of the rear end portion. 2 is disengaged from the engaging claw portion 2a and the engaged portion 1c at the upper end of the lid 1 and the lock of the lid 1 is released.

  Accordingly, as shown in FIG. 5 (c), when the card C is inserted into the slot 4a at the back from the card insertion slot 4, the lid body 1 is rotated by about 90 ° about the shaft 1a in the opening direction (backward). At the same time, the lock release member 3 also rotates together with the lid 1 about 90 ° backward about the shaft 1a, and the lock member 2 stops in a state of being rotated upward by the cam surface 3b of the lock release member 3.

  Then, when the card C is extracted, the lid 1 and the unlocking member 3 rotate in the closing direction (forward) with their own weight, and accordingly, the locking member 2 rotates downward with their own weight, and the engaging claw portion 2a. Engages with the engaged portion 1c at the upper end of the lid 1 from above, and returns to the locked state shown in FIG.

  When the card C is inserted, the protrusions 3a and 3a of the left and right unlocking members 3 and 3 are simultaneously pushed at the tip of the card C, and the engaging claws 2a and 2a of the left and right locking members 2 and 2 and the lid body are inserted. In order to simultaneously disengage the engaged parts 1c and 1c at the upper end, the lock of the lid 1 is released as described above, but when a coin other than the card, for example, tries to enter from the card insertion slot 4 Even if the protrusion 3a of one unlocking member 3 is pushed in by a coin or the like, it is not pushed into the projection 3a of the other unlocking member 3 at the same time. The engagement between the portion 2a and one engaged portion 1c at the upper end of the lid 1 is not released. Accordingly, since the lock of the lid 1 is not released, it is possible to sufficiently prevent coins other than the card from being mixed from the card insertion slot 4.

  As can be understood from the above, the lid locking device of the present invention automatically unlocks the lid when inserting the card, but the lid is not unlocked with anything other than the card. It is possible to prevent such foreign matter from being mixed.
