Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a storage case for storing cassette tapes for music and video.

[0002]

[Prior art]

 For example, as a cassette tape storage case for an automobile, a lid with a lock mechanism is generally known. In this conventional storage case, the means for preventing the automatic opening due to the vibration of the vehicle body is stopped, and in order to take out the cassette tape, it is necessary to open the lid and take it out by hand.

[0003]

[Problems to be solved by the device]

 As described in the prior art, the cassette tape storage case that is stored due to the shaking of the vehicle body naturally opens in automobiles and the like, so a lock device is provided on the lid as a means to prevent it, but when removing the tape one by one. There is the trouble and inconvenience of having to open the lid by hand and take it out. Therefore, the present invention was made in order to eliminate this inconvenience, and in addition to preventing the disadvantage that the case containing the cassette tape is naturally opened due to shaking, it is also possible to open the case and remove the tape. The lock of the drawer is released by simply pushing the push button type finger hook with the fingertip, and then the drawer containing the tape is automatically pulled out to pop out forward. This eliminates the need to pick up the drawers with your fingertips as before, and you can store the tape in the drawer easily by storing the tape in the drawer and then pushing the drawer inward. The drawer was designed so that it could be locked automatically.

[0004]

[Means for Solving the Problems]

 In order to solve the inconvenience of the cassette tape storage case known as the prior art, the present invention provides a rack track along the outside of the one side box edge of the drawer in the drawer type storage case for storing the cassette tape. This rack orbit is meshed with a pinion installed inside the outer box, and this pinion is mounted on the main shaft of the mainspring device.A lever-type operating rod is mounted inside the outer box to support the lever. A lock claw that engages and disengages with a notch groove provided on the box edge of the drawer is provided at the front end, and a button-type finger hook for operation is provided at the rear end of the operating rod. The cassette tape storage case is characterized in that it is formed so that it can be opened by pressing it against and pressing the drawer with a finger hook. The front edge frame of the drawer is rotatably mounted around the support shaft, and when the drawer is pulled out from the outer casing, it should be released so that it can be unlocked in conjunction with the lock-operated finger rest. Is also good.

[0005]

[Action]

 The main shaft of the pinion with the pinion and spiral spring is mounted on a support frame provided outside the frame on one side of the drawer, and the rack track provided along the outside of the box edge on one side of the drawer. Since it engages with the pinion, when the drawer is pushed inward from the open position to the outside of the box, the mainspring shaft rotates in response to the movement of the rack track, tightening the spiral spring, and elastic force is accumulated. At the same time, the lock claw provided at the front end of the operating rod automatically engages with the notch groove provided at the edge of the drawer box by the action of the pressing spring that constantly pushes the operating rod from above. When you push down on the rear end of the operating rod with a finger rest that has room to move up and down, the front of the operating rod is raised against the action of the pressure spring, and the lock pawl is pulled out of the notch groove, so the drawer is tightened. The elastic force of the spiral spring rotates the pinion, moves the rack track that meshes with the pinion, and releases the drawer associated with the track. The box edge on the front side of the drawer is opened. When the front wall of the drawer is rotatably mounted around the support shaft, when the drawer is pulled out from the outer casing, the lock is released to allow free rotation, so that the cassette tape You can take a large entrance and exit.

【Example】

 A drawer 1 for accommodating a cassette tape is inserted and withdrawn in an outer casing 2 whose front is open. On the front surface of the drawer 1, an undulating lid 5 serving as a front wall plate of the drawer 1 is pivotally supported on the drawer 1 by a support shaft 3, and an upper edge 4 of the lid is hung so that it can be laid down sideways. Is provided with a rack track 6 in the front-rear direction, and a spiral spring 9 is installed on a mainspring shaft 8 having a pinion 7 that meshes with the rack 6, and a mainspring device 8a is attached to the mainspring shaft 8 as shown by a dotted line. In connection with this, rapid mainspring winding and constant speed mainspring release are configured. A support plate 11 mounted on the support frame 10 is pivotally supported at an appropriate intermediate position, and a lock claw 14 for engaging and disengaging with a notch groove 13 provided on one side of the drawer box is provided at the front end, and a finger at the rear end. When a lever-type operating rod 16 provided with a hook 15 is installed, and a pressing spring 17 is pressed against the upper surface of the front end of the operating rod to pull out the drawer inserted in the outer casing, lightly lower the finger hook 4 If it is pushed to, the lever-type operating rod is actuated, and the lock claw 14 separates from the notch groove 13 provided in the box edge of the drawer, that is, the lock is released, so that the coiled spiral spring 9 is released and the mainspring. By rotating the shaft 8, the rack track meshing with the pinion 7 moves according to the rotation of the pinion, i.e. the drawer with the rack track is transported, i.e. the drawer is ejected from the outer casing 2. When the drawer is pulled out, the lower edge of the undulating lid 5 on the front edge of the drawer is released, so the undulating lid 5 is tilted down to open the door wide, and the cassette tape for storage is opened so that it can be easily taken out. is there. In the above embodiment, the lock claw 14 is provided at the front end of the lever type operating rod 16, but it may be provided at a member related to the front end instead of the front end. In addition, as shown in FIG. 6, a connector 20 having engaging portions 18, 18 provided on the upper and lower sides of outer surfaces of both side walls of the outer casing 2 and engaging claws 19, 19 provided on upper and lower sides of both side edges thereof is attached to the outer casing 2, as shown in FIG. It is possible to interpose and stack in multiple stages.

[0007]

[Effect of device]

 Since the present invention is configured as described above, when storing a storage item such as a cassette tape in the drawer, there is no fear that the front edge of the drawer will be opened due to the action of shaking or the like, so that the stored items can be safely stored. It can be stored in the drawer, and the outlet on the front side of the drawer is also configured so that it can be automatically opened to a certain width by a simple operation such as a simple push button operation. It is extremely easy to carry out and it has the convenience of being automatically locked when the drawer is pushed in.
