す。2. Description of the Related Art An elongated base plate, a shaft pivotally mounted on a plurality of bearings provided along one side of the base plate, a base supported at predetermined intervals on the shaft, and the other side of the base plate. A loose-leaf binding device having a plurality of binding rings each having a tip portion that contacts and separates from a side, a spring that biases the binding rings in the opening direction at all times, and a locking mechanism that locks the binding rings in a closed state. Is a publicly known, thin-type binding device suitable for binding a relatively small number of loose leaves such as medical charts. The means for opening and closing the binding ring of this type of binding device includes a slide system that converts the movement of the puller into a rotational movement and transmits it to the support shaft of the binding ring,
There is a lever system in which the supporting shaft of the binding loop is directly rotated by a lever with a lock. In the lever system, when the binding ring is closed, the binding ring is directly pressed to close the binding ring and automatically lock the lever in the closed position of the binding ring. On the other hand, when releasing the binding ring, if the lever is pushed in a specific direction to release the locking protrusion of the lever, there is an advantage that the binding ring can be easily opened by the action of the spring. However, since the lock is due to the elasticity of the cantilever lever, the lock tends to come off due to the action of an external force.
The slide system uses a cam-follower mechanism to change the linear motion of the operating plate with a puller into a rotary motion of the shaft. When the binding ring is opened, the puller is pulled, and when closed, it is pushed.

Since the follower mechanism changes the linear movement of the puller into the rotational movement of the shaft, the mechanism is complicated and the board becomes thicker.In addition, pull the puller when the binding ring is opened and push the puller securely to the back when closing the binding ring. It is troublesome for the user because the binding loop is not completely closed. Further, since the slide plate is required to have a rigidity sufficient to withstand this pressing force, it becomes thick. The present invention provides a slide-type binding device that combines the advantages of the lever system and the slide system, is thin, is easy to operate, can easily open and close the binding ring, and can reliably maintain the closed state of the binding ring.

Under the lock release plate 3 in the direction of the spring piece 6.
Assemble by sliding. Similar structures are formed on both sides of the unlock plate at three locations. Since the lock release plate 3 is thin, it may come off from the substrate 1 if it is pulled strongly with more force than necessary. Therefore, at least one protrusion 29 is provided at the same position as shown in FIG. It is preferable that the notch 28 can be stopped at the end wall (stopper) 30 on the side of the leaf spring piece 6 so as not to exceed it. As shown in FIGS. 2, 7, and 12, an opening 18 is formed in the unlocking plate 3 at a position aligned with the opening 8 of the substrate so that the tip 7 of the binding ring 4 extending into the opening 18 is received. When the hook 7 of the binding ring is locked by the locking projection 8 ′ of the substrate 1 when the binding ring 4 is closed, the spring piece 6 is biased to a position where it does not interfere with the tip 7. The biased position is regulated by the stop portion 26, which will be described later after being provided on the finger rest 5. The part that acts so as to disengage the hook part 7 ′ from the locking projection 8 ′ is the wall surface on the side opposite to the finger hook of the opening 18, and when the lock release plate is pulled by the finger hook part 5, this wall surface serves as a binding ring. Push the tip 7 to unlock.

る。As described above, according to the present invention, the hook portion is provided at the front end portion of the binding ring, and the locking projection is provided for locking the hook portion when the front end portion enters the opening of the substrate. Apart from this, the lock release plate, which has a part that acts so as to disengage the hook portion of the binding ring from the locking projection when the finger rest is pulled, is always biased in the direction opposite to the finger rest. The lock is released by pulling the finger hook against the elasticity of the spring piece to open the binding ring, while when closing, the binding ring can be closed by simply pushing the binding ring with a finger and the lock is automatically applied. I chose In this case, since the binding device is basically composed of only three members (four members even if a torsion spring is inserted), the process is shortened, and the lock release plate only needs to withstand tension, so that it is extremely thin. Further, since the spring piece for constantly biasing the unlocking plate in the direction opposite to the finger rest is constituted by the tongue piece formed from an integral part of the board, the number of parts can be reduced. Since the lock release plate is always spring biased in the direction that does not obstruct the lock, the lock part can withstand shock such as vibration sufficiently, and the binding ring can be opened only when the finger hook is pulled sufficiently, so the lock may be released. Is reduced. Further, the finger hook is provided with a standing portion from the lock release plate, and elbow pieces projecting from both sides thereof in a lateral direction with respect to the longitudinal direction of the substrate, and a longitudinal direction for receiving the standing portion in a corresponding portion of the substrate. Since the guide groove and the guide surface for sliding contact with the lower surface of the elbow piece are provided, the thin lock release plate can be firmly held on the substrate surface, and the lock release plate is smoothly guided by the guide groove and the elbow piece. Furthermore, the spring piece is provided with a protrusion projecting toward the other end of the lock release plate, and the other end of the lock release plate has a locking portion that holds the protrusion, and the protrusion has a recess on the other end side. Since the locking portion has a position regulating projection that fits into the recess, assembly can be performed simply by hooking the locking portion of the lock release plate on the protrusion of the spring piece. Can hold a relationship.
