Detailed ways

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 and 2 are diagrams showing a portable barcode reader 1 having a locking mechanism 3 for a battery cover 2 according to the present invention. The reading light optically reads an unillustrated barcode symbol, and transmits the read data to a host computer by wireless communication. In addition, in the barcode reader 1 of the present embodiment, the battery cover 2 that can be opened and closed and detachable is installed on the battery chamber 11 that accommodates the battery pack (or battery) 6 of the casing 10, and the A lock mechanism 3 for locking the battery cover 2 is provided in a lock chamber 12 near the battery chamber 11 . In addition, the barcode reader 1 is provided with a waterproof mechanism 4 for securing the waterproofness between the battery chamber 11 and the battery cover 2, and an extraction mechanism for releasing the battery cover 2 from the casing 10 when an excessive load is applied. 5 (refer to Figure 2).

Bearing holes 21 are formed at two corners of one end surface of the battery cover 2, and a pair of rotating shafts 13A are rotatably installed in the bearing holes 21, and the pair of rotating shafts 13A protrude from the side of the base 13 near the battery chamber 11. settings (refer to Figure 2).

The locking mechanism 3 includes: a locking member 31, which is rotatably arranged in the locking chamber 12 near the battery chamber 11 of the casing 10; rotation force; and the locking piece 22 , which is provided on the battery cover 2 and locked with the locking member 31 .

As shown in FIG. 3 , the locking member 31 has a head 31A protruding in the rotation (α) direction on both sides and a pair of legs 31B protruding downward from the head 31A, and the cross section of the locking member 31 is substantially T-shaped. . Of these, in the head portion 31A, a downwardly inclined slope 311 is provided on a convex portion that protrudes in a certain direction of the battery chamber 11 among the convex portions that protrude toward both sides. Therefore, when the battery cover 2 is pressed in the closing direction, since the locking piece 22 of the battery cover 2 generates a force to push the inclined surface 311 in the -α direction (refer to FIG. 9 ), the locking member 31 also moves towards the unlocked position. - Back in the alpha direction. As a result, the battery cover 2 can enter the battery chamber 11 while the locking member 31 is retreating. Then, the locking member 31 advances in the direction α by the elastic force of the spring member 32, and when it returns to the original position again, the battery cover 2 is locked. On the other hand, an unillustrated shaft hole is penetratingly provided in the leg portion 31B, and the shaft hole is rotatably attached to a support shaft 12A protruding from both side walls in the lock chamber 12 . In addition, on this leg portion 31B, the above-mentioned spring member 32 is provided between it and the lock chamber 12, and the above-mentioned spring member 32 always faces the lock member 31 toward a certain direction of the battery chamber 11 (in FIG. The clockwise direction α) exerts a rotational force.

The spring member 32 is a double pair of torsion springs 32A, 32B integrated structure, the spring member 32 is respectively installed on the fulcrum portion 31D on each leg portion 31B of the lock member 31 (refer to FIG. 3(B). )). Both ends 321 of these torsion springs 32A, 32B protruding laterally are engaged with the bottom surface 12B of the lock chamber 12 . On the other hand, a connecting portion 322 that connects the torsion springs 32A, 32B is formed at a central portion of the spring member 32 . The connecting portion 322 is engaged with the main body portion 31C between the head portion 31A and the leg portion 31B of the lock member 31 , so that the rotational force of the spring member 32 acts on the main body portion 31C through the connecting portion 322 .

The waterproof mechanism 4 is used to prevent rainwater from infiltrating into the battery chamber 11 from the outside after the battery cover 2 is closed, and has a sealing member 41 provided to surround the battery chamber 11 and provided along the periphery of the inner surface side of the battery cover 2 The groove 23 (refer to FIG. 5 ) that fits with the sealing member 41. The sealing member 41 is formed of a material with high stretchability such as silicone rubber, so as to be in close contact with the groove 23 of the battery cover 2 to improve waterproofness. As shown in FIGS. The peripheral portion is provided to surround the battery chamber 11 .

The ejection mechanism 5 is a mechanism that enables the battery cover 2 to be released from the rotating shaft 13A when the battery cover 2 is opened above a certain angle (θ). The above-mentioned bearing hole 21 , which is rotatably supported, is extended and opened toward the outside. This cutout 21A is provided inclined at a predetermined angle (δ) with respect to the outer surface of the battery cover 2 . Therefore, as shown in FIG. 7, when the battery cover 2 is rotated within a certain angle (θ), the bearing hole 21 prevents the battery cover 2 from falling off from the rotation shaft 13A, but as shown in FIG. When the battery cover 2 is rotated by a certain angle (θ) or more due to a heavy load or the like, the battery cover 2 can be easily detached from the rotation shaft 13A.

Next, the operation of this embodiment will be described.

For example, in the case of replacing the battery pack 6, as shown in FIG. Turn in the counterclockwise (-α) direction.

Then, the locking piece 22 of the battery cover 2 locked to the lower surface of the head portion 31A of the locking member 31 is released from the locked state by the turning operation of the locking member 31, so that the battery cover 2 is released from the locked state. Therefore, when the free battery cover 2 is held with fingers or hands and opened upward, the battery cover 2 can be opened as shown in FIG. 7 . In addition, in the state of FIG. 7 , the edge portion 2A of the battery cover 2 between the bearing holes 21 (the central ridge line portion cut into a door frame shape shown in FIG. 2 ) can be locked to the area near the battery chamber 11. On the base 13 (refer to FIG. 2 ), therefore, the battery cover 2 can be temporarily fixed while keeping the posture of fully opening the battery cover 2 .

In addition, when an excessive force or load is applied to further open the battery cover 2 from the state of FIG. 7 , as shown in FIG. The part 2A is a fulcrum of rotation, and continues to rotate beyond the above-mentioned angle (θ). However, in this case, the battery cover 2 supported by the rotating shaft 13A can be detached from the rotating shaft 13A by passing the bearing hole 21 through the notch 21A, so damage to the battery cover 2 and the casing 10 can be avoided.

Next, if the battery pack 6 has been removed from the battery chamber 11 in which the battery cover 2 is opened and replaced with a new battery pack or the like, the battery cover 2 is closed by pressing in with fingers or hands. Then, as shown in FIG. 9 , when the battery cover 2 is closed to the end, the inclined surface 22A of the locking piece 22 pushes the inclined surface 311 provided on the head portion 31A of the locking member 31 . That is, the inclined surface 22A provided on the locking piece 22 of the battery cover 2 presses the inclined surface 311 of the head portion 31A of the locking member 31 from above, thereby generating a force pushing the locking member 31 obliquely upward along the inclined surface 311 . Thus, in FIG. 9 , the locking member 31 overcomes the elastic force of the spring member 32 to obtain a counterclockwise rotational force. As a result, the locking piece 22 of the battery cover 2 goes around the underside of the locking member 31 and enters directly below the head 31A of the head 31A. At this time, if the finger or hand is released from the battery cover 2, the locking member will 31 returns to the original position under the action of the elastic force of the spring member 32, thereby becoming the state where the battery cover 2 is locked.

In this way, when the battery cover 2 is pressed down with a closing force greater than the elastic force of the spring member 32, since the locking member retreats temporarily, the locking piece 22 enters during this period, thereby automatically locking the battery cover 2.

In addition, in this locked state, since the sealing member 41 fixedly arranged around the battery chamber 11 can fit and closely contact with the groove 23 on the inner surface of the battery cover 2 that seals the battery chamber 11, it is possible to seal the battery chamber 11 with the battery cover 2. Waterproof status is obtained in between.

In addition, in the present invention, a switch (not shown) linked to the locking operation of the locking member may be provided, and the power supply of the portable electronic device may be put into a usable state by turning on the switch. In addition, it is also possible to add a safety mechanism, etc., through this safety mechanism, even if the battery pack (or battery) etc. falls out of the portable electronic device during operation such as outdoors, it is possible to prevent instantaneous interruption accidents such as data loss. occurs, and the safety mechanism and the like are linked with the unlocking operation of the locking device.

In addition, this invention is not limited to the said embodiment, It can implement in various forms in the range which does not deviate from the summary of this invention.

Although this invention was demonstrated in detail with reference to the specific embodiment, it is clear for those skilled in the art that various changes and correction can be added without deviating from the mind and range of this invention.
