DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light pen for reading a bar code, which is used to input information of a package slip such as a courier service to a terminal device.

[0002]

2. Description of the Related Art Heretofore, a light pen for reading a bar code of this type has been used by being connected to a small portable information terminal device, and has been used to input bar code information such as a slip number of luggage. However, recently, a large-screen information display device and a portable information terminal device having a touch panel mounted on the surface thereof have been used, and it has become necessary to press the touch panel on the surface with a finger. However, since it is troublesome for the operator to release the light pen and press with the finger only at this time, the operator often tends to press the touch panel with the light pen.

FIG. 3 is a sectional view showing the structure of a conventional bar code reading light pen. In FIG. 3, 1 is a tip of a light pen, 2 is a cylinder, 3 is a cable clamp, 4 is a cable, 5 is a light emitting diode for reading a bar code, 6 is a light receiving transistor, and 7 is an analog light signal. An amplifier section 8 for amplifying is a binarizing circuit section for shaping the waveform of this analog signal and converting it into a digital signal.

[0004]

As described above, since the conventional light pen has a hard metal tip and is entirely in the shape of a metal rod, when the surface of the touch panel is pressed with the tip of the light pen, the force can be adjusted. And the glass on the touch panel surface was damaged.

The present invention has been made to solve such a conventional problem, and has a buffering mechanism between a tip cap and a cylindrical body covering the entirety. It is an object of the present invention to provide a bar code reading light pen that does not damage the glass on the touch panel surface.

[0006]

In order to achieve the object of the present onset Ming, tip cap
Light-emitting diode and light-receiving transistor
The optical sensor part by a resistor etc. and the corresponding barco
And a built-in electric circuit for processing
-In the light pen for reading codes, slide the
A rotatably mounted tip cap, the cylindrical body portion and a tip calibration
Tsu mounted between the flop, to absorb shock tip cap
Switch for turning on / off a buffering mechanism, the electric circuit section
And move the switch to the ON position to
When the part is turned on, the lock mechanism is
And a lever that locks .

[0007]

According to the present invention, both the operation of the input of the reading litho touch <br/> Chipaneru barcode, each time, light pen
Without releasing the hand from the, on enable one-touch operation, damage the glass surface of the touch panel at the time of input of the touch panel
It becomes difficult. According to the present invention, there is provided a bar code reading function.
And the function of the buffer mechanism are controlled by one lever,
The configuration of the light pen is simplified.

[0008]

FIG. 1 is a sectional view showing the structure of a first embodiment of the present invention. In FIG. 1, reference numerals 1 to 8 are the same as those in FIG. , A buffer member, and 11 is a fitting portion for slidably mounting the buffer mechanism constituted by the cap holder 9, the buffer member 10 and the like on the cylindrical body portion 2.

The first embodiment is constructed as described above, and the tip cap 1 has a buffer mechanism so as to reduce an impact by a cap holder 9, a buffer material 10 and a fitting portion 11 which constitute a cap holding mechanism. Thus, even if a force equal to or greater than the strength limit of the touch panel surface is applied to the tip end by impact, the buffer mechanism operates to prevent damage to the touch panel.

FIG. 2 is a sectional view showing the structure of a second embodiment of the present invention. The same reference numerals as those in FIG. 1 denote the same parts, and reference numerals 12 and 13 denote switches and 13 operate the switches 12, respectively. It is a lever.

In the first embodiment shown in FIG.
The impact even impact is applied, the cap holder 9, as it is alleviated by the buffer mechanism constructed in accordance with the buffer member 10 and the fitting portion 11 does not operate said buffering mechanism conversely the take-up saw bar code read It is necessary to adjust the pressing force. The second embodiment is intended to conveniently read-in bar code locks not to operate the function of the pre Kiyuru opposition mechanism. That, and stopper the operation of the buffering mechanism by pressing the lever 13 when the take read the bar code, the same binarization circuit by pressing the switch 12 by the same time lever 13
By turning on the section 8 allows <br/> Rukoto preparative easily read the bar code. Here, the lever 13 is
Moved to the position where the switch 12 arranged inside is pressed down
In the state, the distal end portion of the lever 13 is the outer peripheral surface of the distal end cap 1.
By engaging the opening leading to the switch 12 of
It is restricted that the tip cap 1 slides with respect to the cylindrical body 2.
Therefore, the operation of the buffer mechanism is locked.

[0012]

According to the present invention, as it was more than above Description, according to the present invention,
Misao of both the input of the readings taken Lito touch panel of the bar code
The work, in each case, without removing the hand from the light pen, Wanta
On the effect that performed in pitch operation, the touch panel
It is difficult to damage the glass on the touch panel surface during input
Has the effect . Also, according to the present invention, bar code reading
The function and the function of the shock absorber are controlled by one lever
This has the effect of simplifying the configuration of the light pen.
