本考案は、内部に収納された電子部品に塵埃等

ード８が設けられている。 Optical reading devices are increasingly being used in input parts that process large amounts of information, replacing the conventional key punching. The characteristics of this optical reading device are that it is capable of extremely high-speed processing and has an extremely low rate of misreading, and has recently been applied to management systems such as product inventory and sales. In this case, since the price tag of the product is relatively small, an extremely common optical reading device that moves a reading medium on which characters, symbols, or patterns are printed is used. Such a device is usually called a hand scanner and has an internal structure as shown in FIG. That is, there is a cylindrical hood 2 that supports a lighting device 1 such as a light bulb, a lens barrel 3 to which the hood 2 is detachably attached and which houses a reading lens (not shown), and a rear end of this lens barrel 3. A hand scanner is constituted by a main body 6 in which an image sensor 4 and an electronic component 5 such as an amplifier are incorporated, and a holding plate 7 formed in the hood 2 and to which a lighting device 1 is attached is provided with a lighting device in the center. A cylindrical inner hood 8 for preventing light leakage is provided to prevent illumination light from entering the lens barrel 3 from entering the reading lens.

トしてしまう危険性が多かつた。 When replacing the lighting fixture 1 in such a hand scanner for some reason, remove the hood 2 from the main body 6, remove the lighting fixture 1 from the holding plate 7, and attach a new lighting fixture 1. A hood 2 is attached to the main body 6 so as to fit into a socket 9 provided on the main body 6 side. If the length of the inner hood 8 is increased to such an extent that the inner hood 8 and the lens barrel 3 come into contact with each other, the inner hood 8 and the lens barrel 3 will collide with each other when the hood 2 is attached or removed, and the position of the reading lens may shift. There was a risk that I would end up with something like that. For this reason, in the conventional type, a gap must be formed between the rear end of the inner hood 8 and the front end of the lens barrel 3, and from this gap dust etc. from the inner hood 8 can get mixed in and adhere to the electronic components 5. There was a high risk that the electronic component 5 would be shot.

とする。 The present invention eliminates the drawbacks of conventional hand scanners as described above, eliminates the risk of the reading lens being misaligned when the hood is attached or removed, and has a dust-proof function that prevents dust from adhering to and mixing with electronic components. The purpose is to provide a hand scanner with

A lighting fixture supported by the holding plate around the inner hood, a dustproof wall integrally formed at the tip of the main body to partition the inside of the main body, and a dustproof wall provided at the center of the dustproof wall and the lens barrel. and a dust-proof cylinder that abuts the front end of the inner hood and the rear end of the inner hood to communicate with each other.

在に固定し得るようにしてもよい。 Hereinafter, an embodiment of the hand scanner according to the present invention will be described in detail with reference to FIG. 2 showing its cross-sectional structure. Cylindrical inner hood 1 in the center
A cylindrical hood 13 is formed around the retaining plate 12 on which the inner hood 11 and the hood 13 are formed. A lighting fixture 16 is attached that can fit into a socket 15 provided at the tip of the main body 14. Inside the main body 14 to which the hood 13 is detachably attached to the tip thereof, there is a lens barrel 17 housing a reading lens (not shown) for reading characters, etc. on a reading medium (not shown), and a lens barrel 17.
An image sensor 18 attached to the rear end and electronic components 19 such as an amplifier are incorporated, and the inner hood 11 and the lens barrel are located between the inner hood 11 and the lens barrel 17, which are coaxial with each other. A dustproof cylinder 20 communicating with the main body 17 is integrally fixed to the main body 14 via a dustproof wall 21 formed at the tip of the main body 14. Note that the dustproof cylinder 20 may be detachably fixed to the main body 14.

である。 Therefore, when the hood 13 is attached to and removed from the main body 14, the inner hood 11 only contacts the dustproof tube 20 fixed to the main body 14, and no stress is applied to the lens barrel 17. Moreover, since the dust-proof wall 21 and dust-proof cylinder 20 that partition the inside of the main body 14 are interposed between the inner hood 11 and the lens barrel 17, there is no possibility that dust etc. from the inner hood 11 will reach the electronic components 19. . In this case, if the dustproof tube 20 is made of a soft rubber-like elastic material, the inner hood 11, the dustproof tube 20, and the lens barrel 1
It is possible to further improve the dustproof property of the sealing portion with 7.

等が付着する虞もない。 According to the hand scanner of this invention,
The inner hood and the lens barrel are communicated through a dustproof tube, and the inside of the main body is partitioned by a dustproof wall provided with this dustproof tube, so the position of the reading lens does not shift when the hood is attached or removed, and dust does not get on the electronic components. There is no risk of any contamination.
