2. Description of the Related Art Conventionally, devices such as copying machines and cash dispensers have become more sophisticated in recent years, and their operational functions have become more complex.

For example, when using a bank's cash service with a cash dispenser, etc., insert a magnetic card and follow the displayed steps to input information (information entered through key operations such as PIN number, amount, cancellation, confirmation, etc.) into the device. There must be.

[Problem that the invention seeks to solve]

In particular, in devices that use external light to send and receive information stored on cards, the amount of light that can be received fluctuates depending on the intensity of the external light, resulting in problems such as the inability to send and receive information accurately. there were.

Furthermore, since the information on the card is limited to only one direction, for example, the front surface of the card, there is a problem that the information that can be exchanged is limited and cannot be used for other purposes.

This invention was made to solve the above problems, and is a card that can always stably read the information on the card even if the amount of external light fluctuates, and that can add multiple functions to the card. The purpose is to obtain a reading device.

[Means for solving problems]

The card reading device according to the present invention is equipped with an adjusting means for adjusting the light receiving sensitivity according to the intensity of external light, and a determining means for determining whether the control card is front or back according to the light pattern transmitted through the control cart. .

[Effect]

In this invention, the adjusting means adjusts the light receiving sensitivity of the light received via the control card according to the intensity (light amount) of the incident external light. Further, the determining means determines whether the control card is front or back according to a light pattern transmitted through the control card.

In addition, the CPUI serves as an adjustment means and a determination means of the present invention, and detects external light entering through light receiving windows 15a to 15c, which will be described later, and adjusts the light receiving sensitivity according to the amount of light. The front and back sides of the control card 11 are determined.

FIGS. 2(a) and 2(b) are diagrams for explaining the configuration of a control card showing an embodiment of the present invention. In FIG. 2(a), 11 is a control card having an LCD display 12. The LCD display 12 has a transmitter 13.14.

In the same figure (b), 15 is an operation part, and light receiving windows 15a to 15c for receiving external light are provided.

FIG. 3 is a control block diagram of the control card 11 shown in FIG. 2(a), and 21 is a CPU, which comprehensively controls each part based on the control procedure stored in the ROM 22. A RAM 23 stores control information from an external device (described later) that is input to the signal receiving section 24. A key switch 25 is used to set, for example, a copying function of a copying machine. 26 is a pointing device, for example, an area (coordinates) for image processing
Enter. Reference numeral 27 denotes an LCD display, which serves as the transmitting means of the present invention. Reference numerals 28a to 28d are interface circuits (I/F), which exchange information between 12, 24 to 26 and the CPU 21.

FIG. 4 is a plan view of the control card 11 shown in FIG. 2(a), in which numeral 31 is a card body, and an LCD display 12.1 having a transmitter 13.14. A detection element 32 that detects the state of information transfer from an external device. It is composed of a key switch 33 and the like.

When the power of the card body 31 is turned on, the CPU 21 controls and initializes each section according to the procedure stored in the ROM 22, and waits for input. The signal input from the key switch 25 or pointing device 26 is C
It is stored in the RAM 23 via the PU 21. After the input is completed, when the card body 31 is inserted into the insertion slot 41 of the copying machine shown in FIG. 5, for example, the insertion of the control card 11 is detected by a mechanical switch or a photodetector provided on the copying machine side. .

Next, when the signal output circuit 6 of FIG. 1 excites the coil 6a, the detection element 32 of the signal receiving section 24 of the card body 3]
detects that it is ready to send. In response, the CPU 21 sends the RAM to the transmitter 13 of the LCD display 12.
A transport lock for transferring the information stored in 23 is generated by opening and closing the shutter. This conveyance lock is received by the light receiving element 7a and inputted to the clock input circuit 4 as a conveyance cock, and R is synchronized with this conveyance lock.
The key manual information stored in the AM 23 is sent to the transmitter 13 of the LCD display 12 to open and close the shank. Thereby, when the light passing through the light receiving window 15a passes through the transmitting section 13 and is received by the light receiving element 7b, it is inputted to the signal input circuit 5 as key/input information. At this time, the signal input circuit 5 reads the key manual information in synchronization with the above-mentioned transport lock. Next, the inputted key power information is interpreted and a copying mode corresponding to the key power information is set, for example, in the drive system of a copying machine.

At this time, the area information is input to the operation unit 52 in synchronization with the aforementioned transport cock using external light as the light source.

Note that in the above embodiment, the transmitting units 13 and 14 are transparent type L
Although the number of transmitters is not limited to two, it may be one or more than two.
A reflective type LCD may be used instead of a transmissive type.

Further, in the above embodiment, a detection element (Hall element) 32 is provided in the card body 31 to detect the signal transfer start state, but a reed switch or a conductive wire may be used. In this case, the main body side has a magnetic head or coil. Note that the detection element 32 may be constituted by a light receiving element and the start of signal transmission and reception may be commanded by light, or the start of signal transmission and reception may be commanded by pressing the key switch 33.

Furthermore, since the card body 31 has the CPU 21, it is possible to perform necessary calculations according to numerical inputs from the key switch 33, and it can also be used as an electronic desk calculator.

Further, in the above embodiment, the explanation was given using the operation mode designation operation of a copying machine as an example, but for example, setting of the recitation number and withdrawal amount is performed using the key switch 33 of the card body 3,
By inputting this card body 31 into the cash dispenser, it is possible to omit key touch operations at the KINASH dispenser and shorten waiting time. Note that it is also possible to apply it to a computer terminal.

Furthermore, if the back of the card is equipped with a pressure-sensitive pad, such as a resistive film, that allows coordinate input using an arbitrary pointer, the card can also be used as a pointing device for a computer.

Furthermore, in the above embodiment, the case where the front and back sides of the control card 11 are determined by the light receiving windows 15a to 15c has been described.
As shown in FIG. 7, light receiving windows 15a to 15d are provided,
