The self-latching device comprises a frame (11, 17, 21, 24, 31) arranged to be mounted on the hinged closure member, in particular on a gate, a latch bolt (7) movably mounted on the frame in a horizontal direction between a latching position and a retracted position, a latch bolt spring (70) arranged to bias the latch bolt (7) into the latching position, and operator means (10) mounted on top of the frame so as to be operable from both sides of the closure member (2) and connected by means of a latch bolt operating mechanism to the latch bolt (7) for moving it from the latching to the retracted position. The self-latching device is especially suited for being mounted in a vertical tubular member of or fixed to a safety gate around an area which is dangerous for children, in particular around a swimming pool area.

A sheet conveyance apparatus includes a conveyance roller pair and a mechanism. While following movement of the sheet nipped by the conveyance roller pair, the mechanism moves the conveyance roller pair from a home position, and, in response to a trailing edge of the sheet passing through a conveyance roller pair nip portion, the mechanism returns the pair to the home position. The mechanism includes a movement supporting portion, a cam, a pressing member, and an urging member. The pressing member urges the conveyance roller pair toward the home position by exerting an urging force to the cam. In response to the conveyance roller pair and one of the cam and the pressing member moving in the width direction from the home position, the pressing member exerts the urging force to the cam in a direction reverse to a direction in which the conveyance roller pair has moved.

The invention provides an electric connector for a circuit substrate. A locking metalwork (30) comprises a retained portion (31) which is disposed at one end of the locking metalwork and is maintained to a cover, a locking portion (32) which is disposed at the other end of the metalwork and can be clamped with the locking portion in a connector imbedding direction, a flexible connection portion (33) which is bended in a manner of connecting the retained portion (31) and the locking portion (32). The connection portion (33) has a first arm portion (33A) and a second arm portion (33B) which are separately disposed in a direction vertical to the connector imbedding direction. During the imbedding of the connector, the retained portion (31) is pressed by the locked portion, the first arm portion (33A) connected to the locking portion (32) elastically moves from a direction vertical to the connector imbedding direction to a direction adjacent to the second arm portion (33B), and thereby the locking portion (32) is clamped with the locked portion.

An object of the present invention is to expand a dispensable diameter range of a coin dispenser that can dispense coins having diameters within a predetermined range without the need of part replacement and some sort of adjustment. Coins are dropped into and sorted by through holes one by one by forward rotation of a rotating disk, are guided by a circular coin guiding wall of a storage hole while the coins are pushed by pushers on a lower surface, the coins are then guided in the circumferential direction of the rotating disk by an outlet rotor constituting an outlet guide, are guided by a hopper, and are ejected by an ejecting roller. If coin jamming occurs, the rotating disk is rotated backward, and the coin pushed by a rear surface tip of the pusher is guided by a cylindrical surface of the outlet rotor. Since it is the cylindrical surface, the angle formed by the pushing force by the pusher and the reactive force from the outlet rotor is increased, the coin is returned into the storage hole, backward rotation can be continued, and the coin jamming can be eliminated.

A cutter blade drive mechanism reliably returns a cutter blade from a forward position to a retracted position. A rotation transfer mechanism 34, which transfers rotation of a drive motor 31 to a drive gear 32, has a cutter blade return gear 50 that meshes with the drive gear 32, a compound gear 40 to which rotation from the drive motor 31 is transferred, and a transfer gear 51 that meshes with the compound gear 40 and the cutter blade return gear 50. While an intermittent teeth part 43a of the compound gear 40 and the transfer gear 51 are meshed, the cutter blade 21 moves to the forward position 21A. When the intermittent teeth part 43a and the transfer gear 51 are not meshed and the compound gear-side protrusion 44b of the compound gear 40 is in contact with a cutter blade return protrusion 50b of a cutter blade return gear 50, the cutter blade return gear 50 rotates in unison with the compound gear 40, the drive gear 32 turns in the opposite direction, and the cutter blade 21 returns to the retracted position 21B.

Disclosed herein is a safety syringe. According to the safety syringe of the present invention, an adapter connected to an injection needle is threadedly coupled with the neck of a cylinder while interposing an O-ring therebetween. Thus, the movement of the injection needle is effectively prevented while in use, and thus the injection needle can be pricked accurately at a desired position of the patient's body. Since the adapter is formed with grooves, whereas a plunger is formed with two protrusions positioned diametrically opposite to each other so as to be inserted into the grooves, the adapter is rotated and then moved downwardly in accordance with the successive rotation and downward movements of the plunger after the adapter is released from the neck of the cylinder. The plunger is formed at its upper surface with a vertical rod extending upwardly from an eccentric position, whereas the adapter is defined with a conical cavity. The upper end of the rod is inserted into the cavity while being bent inwardly. When the injection needle is withdrawn into the cylinder, the injection needle is firmly tilted in a lateral direction due to the strong restoring force of the rod so that it can be collapsed simply against the inner surface of the cylinder. In addition, a circular plate is formed at a certain lower position of the plunger. The circular plate enables the user's fingers gripping the safety syringe not to come into contact with the plunger to be entered into the cylinder, thereby achieving the sanitary use of the safety syringe.
