  A control device that receives and monitors the status signals of these various security devices or the status signal of the non-contact card reader is installed as a higher-level model. In addition, when a control apparatus receives an alert signal from a non-contact card reader or a security device, it reports (transmits) to a security center.

  Since the above-mentioned contactless card reader is installed in the vicinity of an entrance such as a door in a warning area, the brightness of the display unit of the contactless card reader and the volume of the speaker are set in advance according to the surrounding environment. In other words, when the place where the contactless card reader is installed is a dark environment even in the daytime, the display has good visibility even with a low light intensity (brightness) setting, and an environment where a lot of noise close to the construction site or transportation is generated. If so, the speaker volume is set high so that the sound can be heard.

Conventionally, a manufacturer or an administrator operates the DIP switch in the contactless card reader, or connects the personal computer etc. and sends the adjustment data as system data to set the volume and light intensity (brightness) as described above. It was.
However, the dip switch operation has been downsized in recent years and requires detailed work, and adjustment data transmission requires a transmission side device such as a personal computer. However, the workability was not good, and the burden of time and human costs was great for the customers.

  Therefore, an object of the present invention is to provide a card reader that does not affect a crime prevention operation (a security operation or an entry / exit operation) and can adjust a volume and a light amount (luminance) by a simple method.

In order to achieve the above object, the invention according to claim 1 is a card reader for reading identification data of an IC card, and a security button for setting and operating the electric lock in a security state and a release button for setting and operating the security lock. And a patrol button operated when a patrolman starts patrol start or patrol cancellation, and a reading operation of identification data of the IC card or a long press operation of two of the three buttons shifts to various setting modes. Or a mode setting unit that terminates the setting mode, a display unit that displays various types of information, and a speaker that outputs alarms and various types of information, and a predetermined reading operation of the IC card or two of the three buttons. previously set the display One buttons the mode of the mode setting unit by long press operation shifts to the luminance adjusting mode of the display unit It is allowed to appear in luminance, or migrating to is output in the pre-set volume of the speaker to the volume control mode of the speaker, the security button and adjust output up button, the said release button as adjusting output down button Brightness adjustment or volume adjustment can be performed by operating an adjustment output up button and the adjustment output down button.

  With the card reader of the present invention, even a person who is not an administrator can adjust the volume and the amount of light (brightness) according to the customer's desire and installation environment without affecting the crime prevention operation.

It is a figure which shows the external appearance of the card reader of this invention. FIG. 2 is a schematic circuit configuration diagram of FIG. 1.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the embodiments described below, an IC card card reading device (card reader) that implements an entrance / exit management function and a security function as one device and an authentication system using the same will be described using the present invention as an example. However, the present invention is not limited to this, and can be applied to a card reader having only one of the functions.
FIG. 1 shows an appearance of a card reader 1 constituting an authentication system having an entrance / exit management function and a security function according to the present embodiment, and FIG. 2 is a schematic circuit configuration diagram of the card reader 1. .

  As shown in FIG. 1, the card reader 1 according to the present embodiment has a control state such as “unlocking”, “verification”, “permitted”, “abnormal”, and processing results on the front surface of the case body 11. Display lamps 12a, 12b, 12c, 12d for notification, an operation button 13a (security button 13a) for giving a command to shift the system to the security state, and an operation for giving a command to shift the system to the security release state Button 13b (release button 13b), porous part 14 for facilitating transmission of sound emitted from built-in speaker 14c, patrol personnel of the security company to the site when intrusion is detected by a human sensor during security An operation button 13c (patrol button 13c) that is operated when the system starts to perform security start (patrol start) or security release (patrol release) is provided. Although not shown, the card reader of FIG. 1 is installed and used on a wall surface near the door at the entrance of the building.

As shown in FIG. 2, the card reader 1 includes an antenna 16b and a transmitter / receiver 16a that perform wireless data transmission / reception with an IC card, a security button 13a, a release button 13b, and a patrol button 13c provided on the front of the case 11. The operation units 13, 13 a, 13 b, 13 c for detecting whether or not each operation button has been operated, signals from these operation button switches are generated to generate a control signal in the card reader 20, or the IC It comprises a control unit 20 that performs communication processing with a card, a ROM 18, a RAM 19, and the like.
Further, an LED driver circuit 12 for lighting and driving the display lamps 12a to 12d ("unlock", "collation", "permission", and "abnormality") provided on the front surface of the case by a control signal from the control unit 20; A speech synthesizer 14a for outputting a sound or an alarm sound according to a control state or a signal processing result, an SP driver circuit 14b for driving a speaker (SP) 14c, and the like are provided.
Further, the control unit 20 transmits a control signal for performing various settings according to the system to be constructed, such as how to light the LED of the present invention, the volume of sound emitted from the speaker 14c, and the type of sound.
In addition, the card reader 1 includes a power supply unit 17 that receives an external power supply voltage of 9 V to 28 V DC and generates an internal power supply voltage Vcc such as 5 V necessary for the operation of each circuit unit.

  The card reader 1 manages the results when each of the “security”, “release”, and “patroll” operation buttons 13a to 13c is operated, or when the card is authenticated by communication with the IC card. Communication for notifying (not shown) is performed. The management device has a function of performing data communication with a plurality of card readers 1 having a configuration as shown in FIG. 2 provided in the system to monitor the entire system and to send a command for opening and closing the door. Configured.

Next, the brightness adjustment and volume adjustment functions of the card reader 1 will be described.
For the sake of simplicity, it is assumed that the brightness of each display unit of the card reader 1 can be set in 3 levels (high brightness, medium brightness, low brightness), and the speaker volume is 3 levels (high, It is assumed that the display unit is set to medium luminance and the speaker volume is set to medium volume in the factory default settings.
In addition, it is assumed that neither brightness adjustment nor volume adjustment can be set to the off state and the silent state.
Further, in brightness adjustment, there are a plurality of display units as shown in FIG. 1, but in FIG. 2 and the following description, a display unit 12d that displays “abnormal” will be described as a representative example.

First, card identification data is read by communication with an IC card (not shown), and if the result of this data verification is authentication, each operation of the card reader 1 can be performed.
Next, when the security button 13a and the release button 13b are pressed at the same time, the control unit 20 shifts to the brightness adjustment mode of various setting modes while continuing the security state or the security release state (setting unit 22).
Here, the security button 13a and the release button 13b are pressed at the same time to shift to various setting modes. However, for example, various setting modes can be performed by continuously tampering with the IC card after IC card authentication. It is good also as a structure which transfers to.
In addition, when a signal such as an intrusion abnormality is received during the various setting modes in the security state, the various setting modes are forcibly terminated, and the display unit 13 and the speaker 14c are alarmed at an initial medium luminance and medium volume. I do.

When shifting to the brightness adjustment mode of the various setting modes, the control unit 20 transmits a control signal for lighting at the brightness of the preset brightness (medium brightness) to the LED driver 12, and the display unit 12d has the brightness of medium brightness. It lights up. In addition, when the display unit 12d is lit before the mode transition, lighting with medium luminance is continued.
In this lighting state, when the security button 13a is pressed once, the control unit 20 determines that the luminance adjustment output up signal has been received, and the high-intensity data stored in the storage unit such as the ROM 18 is set to the LED driver. A luminance output signal is transmitted, and the display unit 12d is lit brighter (increases the amount of light) than that at medium luminance.
That is, the security button 13a also functions as an adjustment output up button for adjusting the brightness.

  When it is desired to set the luminance to be low (light amount is small), the low luminance signal is transmitted to the LED driver by pressing the release button 13b once after shifting to the luminance adjustment mode. That is, the release button 13b also serves as an adjustment output down button for adjusting the brightness.

Next, when ending the brightness adjustment, when the security button 13a and the release button 12b are pressed and held again, the control unit 20 shifts from the brightness adjustment mode to the volume adjustment mode of various setting modes. When shifting to the volume adjustment mode, the control unit 20 transmits a medium volume output signal to the voice synthesis unit 14a based on the medium volume output data stored in the storage unit such as the ROM 18 in advance, and drives the SP driver 14b. A medium volume alarm sound or sound is output from the speaker 14c.
When the security button 13a is pressed once in this medium volume alarm sound output state, the control unit 20 determines that the volume adjustment output up signal has been received, and based on the large volume data stored in the storage unit such as the ROM 18 or the like. Then, a large volume output signal is transmitted to the voice synthesizer 14a, and the SP driver 14b is driven to output an alarm sound or sound from the speaker 14c with a volume larger than the medium volume alarm sound.
That is, the security button 13a also functions as an adjustment output up button for adjusting the volume.

  If it is desired to set the volume to a low level, after shifting to the volume adjustment mode, by pressing the release button 13b once, a small volume signal is transmitted to the voice synthesis unit 14a, and the SP driver 14b is driven to drive the medium volume from the speaker 14c. The alarm sound or sound is output at a volume lower than the alarm sound. That is, the release button 13b also functions as an adjustment output down button for adjusting the volume.

  Next, when the brightness adjustment and the volume adjustment are completed and the various setting modes are ended, when the security button 13a and the release button 12b are pressed and held again, the control unit 20 ends the various setting processing modes and displays them. The lighting of the unit 12d is continued, and the volume output of the speaker 14c is stopped (setting unit 22).

  Although the invention made by the present inventor has been specifically described based on the embodiment, the present invention is not limited to the embodiment. For example, in the above-described embodiment, the case where the entry / exit management function and the security function are applied to an IC card card reader and an authentication system using the card reader that implement the security function as one device has been described. Or it can apply also to the card reader which has only any one function of a security function.

In the embodiment, the luminance adjustment is adjusted by transmitting an output signal corresponding to the luminance. However, the amplification factor of the LED driver 12 may be changed, or the LED driving may be performed by switching the connection resistances having different resistance values. It is good also as a structure which changes an electric current.
Further, the volume adjustment is adjusted by transmitting a volume output signal according to the volume. However, when the electronic volume is built in the voice synthesis portion 14a, the electronic volume is changed by operating the operation unit 13. The gain of the SP driver 14b may be changed.
