DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

In the description of the present invention, the same parts are denoted by the same reference numerals, and repetitive description thereof will be omitted.

2 to 4, the card reader 100 is installed on the outer panel 2, which is a part of the housing of the food waste quantitative device 1 and constitutes the outer housing of the card reader 100.

In addition to the card reader 100, a display 200 is provided on the outer panel 2 for displaying the weight of the food waste, the information of the user, and the payment cost according to the weight of the food waste.

According to the card reader 100 of the present invention, the card accommodation case 10 provided with the upper open-type card receiving groove 11 is installed on the front of the outer panel 2 so that the card insertion and withdrawal can be unified .

At this time, the card housing case 10 is formed to be inclined upward in the front direction with respect to the outer panel 2 so that the card can be easily inserted and withdrawn. In another embodiment, the card housing case 10 may be formed to be parallel to the outer panel 2 perpendicular to the bottom surface.

A card information receiving section 40 including an RFID receiver for receiving information of a card inserted into the card accommodating groove 11 of the card housing case 10 is provided at the rear of the card housing case 10.

One upper operating portion 20 is provided on the upper or upper side of the card housing case 10 to operate in a direction intersecting the card housing case 10 to selectively control access of the card. The upper operation portion 20 selectively opens and closes the card accommodating groove portion 11 so that the user can not withdraw the card at will before receiving the information of the card inserted in the card accommodating groove portion 11 in the card information receiving portion 40 .

On the other hand, the card receiving groove 11 is formed so that the RFID card 300 can be inserted into the card case 10. A folded fault layer 10a is formed on a front surface of the upper part of the case 10 on the front surface of the card case 10. [ That is, the folded single layer portion 10a is formed to be cut from the upper end of the card housing case 10 to the middle portion of the case. Therefore, when the RFID card 300 is inserted into the card receiving groove 11 of the card case 10, one side of the upper end of the RFID card 300 is exposed to the outside through the folded fault layer 10a. The user can grip the upper or a portion of the RFID card 300 exposed to the outside and take out the RFID card 300 from the card receiving groove 11. [ That is, the bending fault section 10a is provided to allow the user to more easily grasp the card by the upper or side of the exposed card.

An example in which the RFID card 300 is exposed by the folding fault section 10a is shown in Fig.

A photo sensor 30 is provided in the lower end of the card case 10. Preferably, at least two photosensors 30 are provided on both sides of the lower end of the card case 10. When the food waste quantitative device 1 is installed in the outdoors, foreign matter such as leaves may be introduced into the upper part. In this case, if only one photosensor 30 is provided, it can be mistakenly recognized that a card is inserted by mistaking a foreign object such as a fallen leaf. Therefore, the photo sensor 30 is attached to both sides of the lower side, and both are monitored to recognize the card insertion. FIG. 6 shows a state in which the photosensor 30 is provided on both sides of the lower end.

Each photo sensor 30 is composed of a light emitting portion 31 and a light receiving portion 32 which face each other with the card accommodation groove portion 11 interposed therebetween. The light emitting portion 31 is an element that emits light, and the light receiving portion 32 is an element that receives and recognizes light. The light emitting unit 31 and the light receiving unit 32 are opposed to each other and sense light emitted from the light emitting unit 31 by the light receiving unit 32.

If an object such as a card exists between the light emitting portion 31 and the light receiving portion 32, the light receiving portion 32 does not sense light. That is, it is possible to determine whether or not the light receiving unit 32 senses the light, and determine whether the RFID card 300 is inserted into the card receiving groove 11. FIG.

As another embodiment, a microswitch that performs a physical switch operation can be used in place of the photosensor 30. That is, when the RFID card 300 is inserted, the micro switch in the lower part of the card receiving groove 11 is turned on and the micro switch is turned off when the RFID card 300 is taken out.

On the other hand, when the card accommodating groove portion 11 of the card accommodating case 10 is inclined with respect to the paper surface or perpendicular to the paper surface and the card is inserted into the card accommodating groove portion 11, the inner wall surface 11a In order to solve this problem, a plurality of protrusions 13 are formed on the entire inner surface 11a of the card receiving groove 11.

Particularly, when the card receiving groove 11 is inclined, it is preferable that the projection 13 is formed on the inclined inner side wall surface 11a which is likely to come into contact with the card. In the case where the card receiving groove 11 is formed vertically on the paper surface, the projections 13 are preferably formed on both sides of the inner wall surface 11a.

Therefore, even if the card is inserted into the card receiving groove 11, the contact area of the card is reduced by the protrusion 13, so that the card is not attached to the inner wall surface 11a and can be easily drawn out.

The control unit 50 for selectively controlling the operation of the upper operation unit 20 and the photosensor 30 by controlling the food waste quantitative apparatus 1 by checking the user information of the card information receiving unit 40, And is connected to the card information receiving unit 40 and the upper operation unit 20 through the interface 70. [ The interface 70 uses an interface conforming to the RS 232C standard.

Accordingly, the control unit 50 receives the user information input to the card information receiving unit 40 and controls a series of operations of the apparatus 10, and in this process, the upper operation unit 20, (30).

In the embodiment of the present invention, the used card and card information receiving section 40 may employ a communication method other than the card and card information receiving section 40 using RFID communication.

On the other hand, the photosensor 30 inputs the sensing result to the controller 50. The control unit 50 drives the relay circuit 60 in accordance with the input value of the photosensor 30. That is, the control unit 50 turns on or off the relay circuit 60 according to the input of the photosensor 30. Specifically, when the control unit 50 turns on the relay circuit 60, the input power is supplied to the interface 70, the LTE module 80, and the ADC module 90, respectively. Further, when the control section 50 turns off the relay circuit 60, the input power source is shut off.

The boot time of the card reader 100 basically takes several seconds to several tens of seconds. Therefore, the user can feel the waiting time after the RFID card 300 is turned on for a long time. Therefore, the card reader 100 always supplies power to maintain the on state. Instead, it lowers the standby power by putting the peripherals associated with the card reader into a low power state. Therefore, the card reader 100 can be operated immediately after the card is inserted. That is, the card reader 100 can be operated immediately without waiting for the boot time.

Next, operation of the card reader 100 according to an embodiment of the present invention will be described with reference to FIG.
