Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power adapter used for various electronic devices.

[0002]

2. Description of the Related Art Conventionally, as an electronic apparatus, a code pattern is optically read from an information recording medium such as paper on which audio information, video information, digital data, and the like are recorded as an optically readable code pattern. Code reading devices are known. Among these code readers, a portable, for example, pen-type code reader has been known in recent years.

FIG. 9 is a sectional view showing an example of the configuration of this kind of code reading apparatus. In FIG. 9, an opening 2 is provided at the front end side of the exterior 1 of the code reader. In addition, a lens frame 6 to which the lenses 3 and 4, the imaging device 5, and the like are integrally attached is disposed inside the opening 2. The lens frame 6 is electrically connected to a board 8 via a connection section 7, and an electrical section 9 on which various circuits are mounted is provided on the board 8.

A box-shaped battery accommodating section 10 is formed on the opposite side of the electrical section 9 with the substrate 8 interposed therebetween. The battery 11 accommodated in the battery accommodating portion 10 is connected to the electrical component 9 via a negative (−) side contact (coil spring) 12 and a positive (+) side contact 13. The battery 10 includes:
Battery cover 16 with hook 14 and hook 15 formed
Is accommodated in the exterior 1. Reference numeral 17 denotes an operation switch, and reference numeral 18 denotes a signal cable for outputting read information to the outside.

Here, the negative contact 12 is formed of a coil spring for the following reason. That is, although the battery is manufactured according to a predetermined plan, its dimensions vary considerably. Therefore, in order to ensure the contact between the battery and the contact, it is necessary to make contact with a certain long stroke. Therefore, in contacting the battery with the contact, a coil spring is used as the contact, the stroke is long, and the force is large.

Since the reaction force of the coil spring is large, the battery 11 is firmly held so that the battery 11 accommodated in the battery accommodating portion 10 is not pushed out by the force applied thereto. The battery housing portion 10 is formed in a box shape for fixing.

[0007]

Since the portable code reader as described above uses a battery as a power source, its operation time is limited. Therefore, it has been desired to extend the operation time by using a power adapter capable of supplying power from the outside.

However, if the power supply circuit section of the power supply adapter is to be mounted in the battery accommodating section 10 of the portable code reader in place of the battery 11, as described above, the large reaction force of the negative side contact 12 will be exerted. In this case, the power adapter is attached to the battery, so that the power at the time of attachment becomes large.
It is necessary that the hooks 14 and the hooks 15 that support the support have a certain strength. As a result, the hook 14
The hook 15 and the hook 15 increase the thickness of the entire apparatus, and if the hooks 14 and the hooks 15 are made of plastic in order to have the required strength, they will change over time. Therefore, there is a possibility that a rack may be generated or an accounting may occur.

Japanese Utility Model Publication No. 4-16355 discloses a technique of a power adapter which covers a reaction force in a contact direction of a battery terminal. In this structure, the reaction force of the contact points directly with respect to the pressing direction of the battery, so that strength is required for the cover portion. Then, there is a possibility that the cover may be cracked or deformed due to a change with time. Note that Japanese Utility Model Publication No. 4-16355 does not specify a spring for a battery.

[0010] Also, Japanese Patent Publication No. Sho 61-2253 discloses that
There is disclosed a technique in which a battery is inserted while moving a spring. In Japanese Patent Publication No. 61-2253, a battery is inserted while a coil spring that generates a relatively large amount of force is pressed in a compression direction.
However, even in the technique disclosed in Japanese Patent Publication No. 61-2253, the workability at the time of mounting the battery is poor because the power at the time of mounting the battery is large.

Therefore, an object of the present invention is to provide a structure in which a lid mounted on a main body is not deformed or cracked even when an elastically deformable member such as a coil spring or a leaf spring is used as a contact on the main body. Another object of the present invention is to provide a power adapter which can be easily mounted and which can supply power from the outside.
