Abstract

PURPOSE:To omit the adjustment of volume of one's voice and simplify a controlling circuit by incorporating a sounding body into a portable operating part of an information reader. CONSTITUTION:A sounding body 15 is incorporated into a protable operating part of an information reader which can read out data manually and the body 15 is controlled. Consequently, checking sound and reading-out status are informed to the operator at the time of operation, and selection of a setting position of a decoder 3 is made unnecessary and volume adjustment also is made unnecessary.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information reading device that optically reads a foreign information card.

Conventional hand-held information reading devices that input PO8 information in supermarkets and department stores have been used to notify the operator of reading completion or reading status by holding a buzzer or speaker inside the reading device rack. I was letting you know.

However, in this case, the appropriate volume of the buzzer or speaker to inform the operator varies depending on the location where the decoding device is placed or the environment in which the information reading device is placed, and the volume of the buzzer or speaker varies each time. It was necessary to adjust the volume, and the drive circuits for the speaker and buzzer had to be designed to the maximum volume for which they would be used.

In order to solve this problem, the present invention has a structure in which a sounding body such as a buzzer is placed inside a manually operated hand-held reading unit to inform the operator of the information reading device of the completion of reading or the reading status. The object of the present invention is to simply inform the operator of the reading status without fail, eliminate the need to select a location for the decoding device, and eliminate the need to adjust the volume.

An embodiment of the present invention shown in the drawings will be described below. 1st
The figure shows a schematic diagram of the information reading device that is read by a hand-held reader. The per food information on the information card 4 is converted into an electrical signal by manual operation of the hand-held reader l, which is connected to the decoding device 3 by Cape A/Yuki, and the decoding device 3 decodes the information of this information card number. It is configured.

This figure shows the internal configuration of this hand-held reading unit 10.
0 is an image sensor that converts the image of the information card number into an electrical signal, 11 is a signal amplification circuit that drives the image sensor IO, an amplification section that amplifies the electrical signal of the converted image, and a resistor 11O shown in FIG. , and a capacitor 111. 13 is a lamp that illuminates the information card, Ig, 1
Reference numeral 4 includes a mirror and a lens, which are arranged so as to form an image of the information card number placed on the reading tray on the image sensor l. 15 is the sounding body of the buzzer, and 16 is its resonance box.

FIG. 8 is a circuit diagram showing a driving circuit for the lamp 11 and the sounding body 150 shown in FIG. 1
11 is configured as a part of the signal amplification circuit 11.

Further, the lamp drive circuit is driven by a drive circuit within the decoding device 8.

The operation of the above configuration will be explained. When reading the information on the information card 4, the information card is brought to the reading opening of the hand-held reading section 1 (by manual operation). Then, the information card number is illuminated by the illumination lamp 1B, and the reflected light illuminates the image center of the information card number through the image lock 1B and VnXI 4, which is proportional to the brightness and darkness of the image. It is converted into an electric signal, amplified by the amplifier circuit in the signal amplification circuit 11, and sent to the cape fi/! is transmitted to the decoding device 8 through the deciphering device 8. This decoding device 8 is a known one, and Cape/L/! A good electric signal is transmitted by a binary value digital μ of bright and dark.
When the amount of brightness and darkness converted into f-value matches certain predetermined information data, it means that the information of the information guard group has been read.

At this time, in order to notify the reading operator of a signal indicating that the reading was successful, the decoder 8 sends a signal to the signal line a of the lamp 1m of the hand-held reading unit l as shown in FIG. Adding the intermittent darkness signal, lamp 1! #it,
It becomes dark for a period of time, but a signal with a period of t. You can know the person who read Yoheto 4.

In addition, while the information card 1 is being read and the decoding device 8 is decoding, the illumination lamp 12 is turned on until the time shown in Fig. 11 and for the time t1 after the buzzer has finished sounding. Apply voltage and turn on the light. In this case, the sounding body 15 is held back and the good signal does not change, so it does not vibrate and does not emit sound.

T again! The lights will be dimmed during the time, but the information card 4
Operation dark time l, after reading , until reading the next information card. If you set the time to a short time of 0.1 seconds to O.S seconds, there will be no problem in reading the information card.

By changing the period of 9t], for example, 045 (
! F% (4KHz) and 1 second (IKHz) $
(c) When the reading is completed, the information card 4 is set to two internal sounds.l) o, *sThe information card 4 is driven at a cycle of 1 millisecond, and the information card 4 is read. (If information card B is read, the buzzer will sound for 0.35 milliseconds, and if information card B is read, the buzzer will sound for lfiν seconds), and the type of information card is also reported to the operator. be able to.

Even if the period of t-#-1t@ is not changed and the period of Kt20 hours is changed, the operator can be notified as a different signal called Pitch.

Furthermore, if there is an abnormality in the decoding device 3, regardless of the operation of the hand-held reader 10, this illumination lamp 12, the sounding body
By adding a signal with a period of 1° or t2 different from the reading completion signal to the signal a to the signal a, the sounding body 15 can have a different frequency or a different time, and the above-mentioned Og! The company is closed,
Although the signals for controlling the information card reading lamp 11 and the buzzer are the same, the reading lamp 11 and the sounding body 15t) are connected separately on the back side, and the decoding device W8) is used separately. Even if it is controlled, the function of Oka can be improved.

Although nine embodiments have been shown using the sounding body and the standard II16, the whole hand-held reading unit can be used as a resonance box to create a %, ah
.

(9) The sounding body 15 can be composed of either a piezoelectric type buzzer or a magnetic carp μ type lurzer.

As described above, according to the present invention, by arranging a sounding body in the hand-held reading unit of an information reading device that reads information by hand, and controlling the sounding body, the sounding body can be used to display a confirmation sound and a reading status to the operator during operation. In addition to informing the operator of changes in the shoulder circumference, the decoding device must be nearby (one at hand) during operation, so the decoding device is not limited to the installation location, and the operator must be informed of any changes in the shoulder circumference environment. Not only this, but also the volume of the sounding device used can be reduced by 90 degrees near the operator, and the control circuit can also be simplified.
