Description

  The present invention relates to a non-contact communication terminal, and more particularly, a non-contact IC card reader configured to read the identification information from a portable device such as a non-contact IC card, a tag, or a mobile phone that stores individual identification information, The present invention relates to a general-purpose non-contact communication terminal in which a key input operation device provided on the front surface of a card reader body such as a tag reader can be replaced.

  As one of non-contact communication terminals, a non-contact ID system used for entrance / exit management has been proposed. FIG. 22 shows an internal circuit configuration diagram of a non-contact IC card reader and an IC card constituting the non-contact ID system (for example, Patent Document 1). As shown in FIG. 22, the card reader includes a control circuit unit 2110, a modulation circuit unit 2120, an RF transmission circuit unit 2130, an RF reception circuit unit 2150, a demodulation circuit unit 2140, an antenna 3160, and a password. Etc., and a numeric keypad 2170 for inputting. As described above, the numeric keypad 2170 is disposed on the outer surface of the card reader body S. Circuits other than the numeric keypad 2170 and the antenna 3160 are provided on the circuit board and constitute the circuit unit 20. The information is read from the IC card C, but the operation will be described later.

FIG. 23 is an exploded perspective view showing the structure of the card reader.
As shown in FIG. 23, the antenna 3160 and the circuit unit 100a are housed in a case 100c and covered with a decorative board 100b. Further, a numeric keypad 170 constituting a key input operation device is attached to the surface of the decorative plate 100b, that is, the front side of the card reader body. The ten-key sheet 170 is connected to the circuit unit 100a by a ten-key cable 171.

  On the card reader 100 side, the user is allowed to input a personal identification number from the ten-key sheet 170 (see FIG. 22), so that double verification for identity verification is performed. Execute the approval action.

  In other words, this type of non-contact ID system can enhance the security function by performing a password input operation using a numeric keypad in addition to card verification.

By the way, since this kind of non-contact ID system is used in various scenes, different numeric keypad sheets are used depending on the type of input function such as presence / absence of an input function, presence / absence of a warning set / release function, and presence / absence of a numeric keypad input function. It was necessary to prepare a contactless ID system with 170.
In addition, depending on whether the product is for indoor use or for outdoor use, it is necessary to use different colors depending on the presence or absence of waterproof coating, or to provide color variations in relation to the color of the wall surface.

  In such a situation, there is a problem that the delivery time becomes long because the type is set for each function and the production is made to order. In addition, it is necessary to design a part corresponding to the function, and there is a problem that the production becomes a small quantity and a variety of products, and the cost increases.

  In addition, when trying to make the panel molded product common depending on the presence or absence of key input, it is usually manufactured based on a molded product that assumes key input, and when there is no key input, unevenness of the key input part etc. Another process such as cutting unnecessary shapes is required. For this reason, there has been a problem that the cost increases.

As is clear from the comparison between FIG. 15 and FIG. 16, the movable button 28 as an actuator corresponding to the numeric keypad (operation key k) is present in FIG. 15 but not present in FIG. 16.

The front cover 10 is mounted on a card reader main body S fixed to the front surface of the exposed base 70 via an adhesive 80 via an adhesive 81 and includes a panel 11 and a front sheet 12. . And this panel 11 is comprised with the resin molding, and has the movable button 28 as an actuator in a corresponding location.
Further, the top sheet 12 is composed of a first top sheet 12a and a second top sheet 12b, and in the region where the movable button 28 corresponding to the operation portion, that is, the operation key k exists, as shown in FIGS. A one-layer structure is used, and a two-layer structure is used outside the above region.

  That is, as shown in FIG. 13, in the area where the movable button 28 corresponding to the operation key k exists, it is configured with a single-layer structure of only the first topsheet 12a. Thereby, not only the step difference from the region where the movable button 28 does not exist is reduced, but also the flexibility of the topsheet is improved and it becomes easy to displace. Moreover, the spacer 125 can be made thicker by the thickness of the second surface sheet 12b by configuring the single surface structure with only the first surface sheet 12a. For this reason, the touch, that is, the click feeling that the first top sheet 12a presses the movable button 28 via the spacer 125 can be enhanced.

  As described above, the surface sheet has a single-layer structure in the region where the movable button 28 corresponding to the operation key k exists, and the surface sheet has a two-layer structure in other regions, thereby reducing the surface step. The operability can be improved.

  Further, as shown in FIGS. 13 to 16, the circuit unit 20 is formed of a multilayer substrate. In the circuit unit 20, a flexible substrate (FPC) 203 is formed on the LED mounting unit 201 via an LED spacer 202. An upper contact 205a is disposed on the contact sheet 205 so as to face the lower contact 203a connected to the circuit formed on the flexible substrate 203. The distance between the lower contact 203a and the upper contact 205a is a spacer 204. Secured by. Further, a metal dome 206M is disposed on the back surface of the contact sheet 205, and a surface protection sheet 208 is mounted via a metal dome spacer 206 and a metal dome presser 207.

For example, as shown in FIG. 13, when the key portion is pressed, the spacer 125 is pressed and the movable button 28 is pressed. At this time, the metal dome 206M is displaced via the surface protection sheet 208. Then, the metal dome 206M is displaced, the upper contact 205a is displaced through the contact sheet 205, contacts the lower contact 203a, and is turned on to turn on the LED lighting circuit of the flexible substrate 203, and the LED 27 ( (See FIG. 20).
Thereby, the switching operation is reliably and efficiently transmitted to the circuit unit, and the desired operation is realized.

Next, the card reader body S including the circuit unit 20 will be briefly described.
As shown in FIG. 23, the card reader body S includes a control circuit unit 2110, a modulation circuit unit 2120, an RF transmission circuit unit 2130, an RF reception circuit unit 2150, a demodulation circuit unit 2140, and an antenna 3160. And a numeric keypad 2170 for inputting a personal identification number or the like. As described above, the numeric keypad 2170 is disposed on the outer surface of the card reader body S. Circuits other than the numeric keypad 2170 and the antenna 3160 are provided on the circuit board and constitute the circuit unit 20. The control circuit unit 2110 controls and encodes / decodes the following circuits. Further, the modulation circuit unit 2120 modulates a carrier wave with transmission data. Further, the RF transmission circuit unit 2130 performs amplification until a desired transmission power is obtained. Further, the RF receiving circuit unit 2150 has a built-in filter that amplifies the return signal from the IC card C and limits the band. The demodulation circuit unit 2140 demodulates the modulation signal returned from the IC card C. The antenna 3160 is used to communicate with the IC card C. This numeric keypad constitutes a part of the operation key k.

  The IC card C includes a control circuit unit 210, a memory 220, a demodulation circuit unit 240, a modulation circuit unit 230, a power generation circuit unit 250, and an antenna 260. The control circuit unit 210 performs control and encoding / decoding of the following circuits. The memory 220 stores identification information and the like. The demodulation circuit unit 240 demodulates the interrogation signal from the card reader body S. The modulation circuit unit 230 modulates with data responding to a signal from the card reader body S. The power supply generation circuit unit 250 generates a power supply voltage used internally. The antenna 260 is used to communicate with the card reader body S.

  Next, the operation when the user holds the IC card C over the non-contact IC card reader will be described.

  The card reader main body S generates an interrogation signal by the control circuit unit 2110 and encodes it, modulates it by the modulation circuit unit 2120, amplifies it by the RF transmission circuit unit 2130, and then sends it to the IC card C via the antenna 3160. Send a signal.

  The IC card C generates power to be used internally by the power generation circuit 250 based on the transmission signal from the card reader body S. After demodulating the interrogation signal by the demodulating circuit unit 240 to which power is supplied from the power generation circuit 250, the control circuit unit 210 decodes and interrogates the interrogation signal. The control circuit unit 210 generates a response signal including the identification information stored in the memory 220, modulates the unmodulated carrier wave from the card reader body S by the modulation circuit unit 230, and transmits the card via the antenna 260. A signal is returned to the reader body S.

  Next, the card reader main body S identifies the IC card C by receiving the reply signal in the RF receiving circuit unit 2150 and the demodulating circuit unit 2140 and then decoding in the control circuit unit 2110.

  Further, on the card reader body S side, by allowing the user to input a personal identification number from the numeric keypad 2170, double verification for identification is performed, and after being authenticated, an approval operation such as unlocking the door is executed. To do.

  That is, this type of non-contact ID system reinforces the security function by allowing a password input operation using a numeric keypad in addition to card verification.

  When an alternating current is passed through a coil-type antenna 3160 provided in the card reader body S, a high-frequency alternating magnetic field is generated in the air by electromagnetic induction. When the IC card C is opposed to the card reader main body S, the loop antenna 260 in the card receives an alternating magnetic field from the antenna 2160 of the card reader main body S. An AC voltage is generated in the IC card C that has received an AC magnetic field, and this is rectified to a direct current to serve as a power source for operating the IC. Thereafter, communication is performed between the card reader body S and the IC card C.

  In the case of a card reader provided with a numeric keypad sheet 22 (see FIG. 3), the numeric keypad sheet 22 is disposed on the front surface of the card reader main body S, so that the IC card C receives an alternating magnetic field via the numeric keypad sheet 22. Become.

  That is, communication between the card reader main body S and the IC card C is performed so that the magnetic field passes through the numeric keypad sheet 22 incorporating the matrix circuit. On the other hand, in the numeric keypad 22, when the key is pressed, a closed loop is formed in the matrix circuit. In this way, the IC card is read.

As described above, according to the non-contact IC card reader of the present embodiment, MT can be realized by sharing a main body with many processes (board mounting, assembly, inspection, etc.). Therefore, the cost can be reduced by mass merit. In addition, it becomes function selection by panel variation with few processing, and it becomes possible to cope with short delivery time.
Furthermore, since the desired processing function can be operated simply by operating the setting unit and replacing the surface cover, it is possible to cope with changes in user needs after installation.

In this way, it is possible to use for five kinds of applications only by exchanging only the surface sheet and the panel, and the production is easy and inexpensive.
In addition, based on a panel that assumes a flat key input and no key input, handling is easy because it is only necessary to affix a surface sheet to a panel molded product.
When there is a key input, the execution of the operation is established by transmitting the key operation using the top sheet with the spacer attached to the back side of the embossed portion.
Moreover, the presence or absence of key input is realizable only with the variation of a surface sheet.
Furthermore, according to the said structure, it becomes possible to eliminate post-processing of a panel molded product, and it becomes possible to reduce cost.

Moreover, in this Embodiment, LED27 is integrated in a sheet | seat switch, and the switch and LED27 are integrated.
Therefore, the number of parts is reduced. Since the number of assembly steps can be reduced, the cost can be reduced.

  As described above, in the case where there is no key input or in the portion where there is no key input on the surface sheet, the key-shaped subtle irregularities of the panel molded product appear on the surface of the surface sheet and the appearance is impaired. On the other hand, if the thickness of the top sheet is increased in order to avoid this, the embossed portion is difficult to bend and the operational feeling of key input is impaired. Therefore, when there is no key input, the surface sheet is thickened, and when there is key input, a two-layer structure with a thick sheet and a thin sheet at the key part is used. improves. In this way, it is possible to achieve a coherent appearance with no unevenness without impairing the operational feeling of key input.

The spacer is preferably composed of two layers. In this case, it is desirable that the sponge S1 positioned on the top sheet side of the spacer has a lower hardness than the sponge S2 positioned on the panel side.
Also in this case, as in the second embodiment, the spacer has a soft sponge 125S1 on the key portion side, so that the contact surface with the first topsheet 12a becomes elastic and soft, so that it can be used for a long time. Even during use, the surface sheet can be prevented from being damaged by wear. Further, by using the spacer 125S2 having a higher hardness on the panel side, it is possible to provide an appropriate hardness, and the first surface sheet 12a presses the movable button 28 through the spacer 125, thereby providing a touch, that is, a click feeling. Can be increased.
According to this configuration, the operation can be performed more easily and efficiently.

According to this configuration, the operation can be performed more easily and efficiently.
This configuration can be used for five types of applications by simply replacing the front cover 10.
In the present embodiment, as shown in FIG. 20, the LED 27 is incorporated into the sheet switch, so that the switch and the LED 27 are integrated.
Therefore, the number of parts is reduced. Since the number of assembly steps can be reduced, the cost can be reduced.

In the first to fourth embodiments, the position of the spacer on the back side of the embossed portion of the panel 12 of the front cover 10 is slightly shifted from the central portion to the opposite side of the fulcrum instead of the key central portion in the case of one side fulcrum. Thus, displacement becomes easier.
Also, if the area of embossing is large or the like is easy to bend, increase the thickness of the spacer. It can be realized. According to this configuration, a good operational feeling can be obtained regardless of the shape.

  Further, the shape of the operation key as the key input unit may be round or square depending on the function, but any shape can be accommodated by making the shape of the operation key elliptical. Therefore, it is not necessary to change the molded product depending on the shape of the input unit, and versatility can be improved.
