DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An object position recognition apparatus according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a conceptual diagram showing the overall configuration of an object position recognition device 10 of the first embodiment. In the object position recognition device 10 shown in the figure, a plurality of elongated transmission / reception coils 11 and 12 are arranged in a matrix at regular intervals, and are adjacent to each other on the lower surface of the mounting plane or the moving plane of the detection object. Is provided. In this embodiment, the transmission / reception coils 11a to 11f are arranged in the row direction (vertical direction).
And the transmission / reception coils 12a to 12f are arranged in the column direction (horizontal direction).

Each transmission / reception coil 11 is formed integrally with a transmission coil 13s and a reception coil 13r so as to have a track shape as described later. The transmission / reception coil 12 is also composed of a transmission coil 14s and a reception coil 14r, and is integrally formed so as to have the same track shape.

Next, for the transmission / reception coils 12a-12f,
Transmission / reception means 16a to 16f (transmission / reception means of the first group), respectively
Is connected. Also, the transmitting / receiving means 15a to 15f (second group transmitting / receiving means) are connected to the transmitting / receiving coils 11a to 11f, respectively. The transmitting / receiving means 15 and 16 supply a current of a carrier signal to the transmitting coil to generate an AC magnetic flux, detect an electromagnetic induction signal received by the receiving coil via a sensing object, and determine whether there is residual vibration of the signal. , Is a means for demodulating the data of the detected object.

FIG. 2 is an explanatory diagram showing the relationship between the detecting device 18 including the transmitting coil (L1), the receiving coil (L3), and the transmitting / receiving means, and the memory device 17 attached to the detected object. The memory device 17, also called a data carrier (DC), includes a resonance circuit in which a transmission / reception coil L2 and a capacitor C2 are connected in parallel, and a braking resistor R and a switch SW are provided in series at both ends thereof. Also memory device 1
A memory control unit 7 is connected between the memory 17a for storing identification data and the resonance circuit, decodes a transmitted command to read data from the memory 17a, and controls opening / closing of the switch SW based on the read data. Part 17b
have. The memory control unit 17b, the resistor R, and the switch SW constitute a data transmission means.

The transmission coil L1 generates an intermittently oscillating electromagnetic field having first and second duty ratios based on the transmission data when transmitting data, and an intermittently oscillating electromagnetic field having a third duty ratio when receiving data. It is a coil that generates a field. When a signal is transmitted from the detection device 18 to the memory device 17, it is transmitted by changing the first and second duty ratios according to the input data.

Here, the transmitting coil L1 corresponds to the transmitting coils 13s and 14s of FIG. 1, and the receiving coil L3 corresponds to the receiving coils 13r and 14r. In the memory device 17, the transmission / reception coil L2 resonates with the AC magnetic field (carrier signal) output from the transmission coil L1, and when the AC magnetic flux is cut off from the transmission coil L1, the residual vibration is generated at both ends thereof. Further, since the drive power supply of the memory device 17 uses the one obtained by rectifying and detecting the AC magnetic field generated by the transmission coil L1, it is not necessary to provide a power supply such as a battery and can be constructed in a very small size.

On the other hand, the switch SW is opened / closed based on the data transferred from the memory device 17 to the detection device 18, and when the switch SW is opened, the residual vibration is received by the receiving coil L3. When the switch SW is closed, the residual vibration in the transmission / reception coil L2 is suppressed, the magnetic flux does not change, and the data is not returned to the reception coil L3. In this way, the memory device 17 reads the command and data of the detection device 18, stores the data in the memory 17a, and reads the data.

On the other hand, the receiving coil L3 and the capacitor C3 are connected in parallel to form a resonance circuit. The resonance frequency is the same as the resonance circuit of the memory device 17. Therefore, the detection device 18 can detect the data signal output from the memory device 17 in a non-contact and highly sensitive manner. Therefore, it is possible to combine a plurality of sets of the memory devices 17 and provide them on a tool for machine tools or dice to be described later. A data communication device having such a principle is disclosed in, for example, Japanese Patent Laid-Open No. 1-151832.

As described above, the transmitting / receiving means 15 shown in FIG.
Reference numeral 16 denotes a transmitter coil L1 and a receiver coil L3.
The detecting device 18 is constructed, and the transmitting / receiving means 15 and 16 have a data modulating section connected to the transmitting coil L1 and a data demodulating section connected to the receiving coil L3.

The horizontal switching means 19 (first direction switching means) shown in FIG. 1 is a means for selectively switching the transmitting / receiving means 16a to 16f in the horizontal direction based on the switching control signal from the control means 21. Similarly, the vertical direction switching means 20 (second direction switching means) is also means for selectively switching the transmitting / receiving means 15a to 15f in the vertical direction based on the switching control signal of the control means 21. The control means 21 outputs a switching control signal to the horizontal direction switching means 19 and the vertical direction switching means 20 and inputs the received data transferred from these means, and the upper communication means 2
It works to output the data to the higher-level device via 2.

Next, the transmitting / receiving coil 11 will be described with reference to FIGS.
A detection panel in which the and 12 are built will be described. FIG. 3 is a perspective view showing the outer appearance of the detection panel 23 connected to the control means 21. The detection panel 23 is a square flat plate, the upper surface of which serves as a detection surface 23a, and the transmission / reception coils 11 and 12 shown in FIG. The control means 21 exchanges data with a higher-level device. Each of the detection objects X1 and X2 has a memory device 17, and the detection surface 2
It is an object that can move freely on 3a.

FIG. 4 is a sectional view showing a state in which the detection object X including the memory device 17 contacts the detection panel 23. In each of the transmission / reception coils 12a to 12d, the transmission coil 14s and the reception coil 14r are embedded in the detection panel 23 so as to be adjacent to each other, and the detectable regions 25 shown by hatched portions are arranged so as to overlap each other at the boundary portion. There is. As shown in FIG. 4, when one memory device 17 in the detected object X contacts the detection surface 23a, the transmitting and receiving coils 12b and 12c in the column direction transmit and receive data to and from the memory device 17.

The operation of the object position recognizing device 10 of the first embodiment constructed as above will be described. FIG. 5 shows that when one or two detection objects X are present on the detection panel 23,
It is explanatory drawing which showed the method of identifying the position of the detection object X, and its type (identification data). FIG. 5A shows the detected object X1.
Is at the intersection of the transmitting and receiving coils 11c and 12d. 6 and 7 are flowcharts showing the operation procedure of the object position recognition device 10.

When a horizontal switching control signal is output by the control means 21 shown in FIG. 1, step S1 in FIG. 6A is performed.
First, the lateral direction switching means 19 is operated as shown by. At this time, the transmitting / receiving means 16a first causes the transmitting / receiving coil 12 to
a is driven, and in step S2, a read command of data of a constant frequency is emitted from the transmission coil 14s. In this case, since the sensing object X does not exist on the transmission / reception coil 12a, the residual vibration is not returned and the reception coil 14 is not returned.
Only the leakage magnetic flux directly output from the transmission coil 14s is incident on r. In this case, the transmitting / receiving means 1 in step S3
6a determines that the detected object X does not exist in this row, and outputs the signal to the control means 21 via the lateral direction switching means 19. At this time, the process proceeds from step S3 to step S6,
It is determined that communication is impossible.

In step S7, the number of the transmitting / receiving coil 12 is incremented. If the number is not the last in step S8, the process proceeds to step S9. In this step, the lateral direction switching means 19 switches to the transmitting / receiving means 16b and performs the same operation as the transmitting / receiving means 16a. FIG. 5 (a)
In such a state, the detection object X is not detected at this position, and the transmission / reception means 16c and 16d are sequentially switched. When the transmitting / receiving means 16d operates, the detected object X
1 exists on the transmission / reception coil 12d, the detection object X
From the memory device 17 built in 1 to the switch SW of FIG.
Data is transferred by opening and closing. At this time, the control means 2
1 is in this column, and it is determined that the detected object X1 exists in any row. At this time, since it is determined in step S3 that there is reception, the process proceeds to step S4 and the number is saved, and the read data is also saved in step S5. Similarly, the transmitting / receiving means 16e and 16f are switched by the lateral switching means 19 to detect whether or not a sensing object is present in each row. As described above, steps S1 to S
Up to 8 shows the detection operation in each column direction.

FIG. 6B shows a memory map of the main memory, which is provided with an area for storing the selected coil number and the detection information of each coil. This is because each detection information is stored so as to correspond to a plurality of detection objects. The storage area of each detection information stores the horizontal coil number, the vertical coil number, and the read data of the detected object.
When the detection operation of all the transmitting and receiving coils 12 in the horizontal direction is completed in step S8, the process proceeds to step S10 in FIG. 7 and the operation is switched to the operation of the transmitting and receiving coils 11 in the vertical direction.

Next, the control means 21 causes the vertical direction switching means 20.
A switching control signal in the vertical direction is output to, and first, the transmitting / receiving means 15a operates the transmitting / receiving coil 11a. At this time also, in step S11, the data read command is transmitted by the transmission coil 13s. At this time, the transmitting / receiving means 15a
If the residual vibration is not received by the receiving coil 13r, the process proceeds from step S12 to step S15, and it is determined that communication is impossible. In this way, it is determined that the detected object X does not exist at this position. At this time, the process proceeds to step S16, and the number of the receiving coil which cannot be communicated at present is saved.

Similarly, when the transmitting / receiving means 15c is operated by the vertical direction switching means 20, if the detected object X1 is in the position shown in FIG. 6 (a), residual vibration is detected in the receiving coil 13r. At this time, the control means 21 stores the number of the transmission / reception coil 11c in the vertical direction in step S13, and saves the read data in the main memory in step S14.

This operation is performed in steps S17 and S18.
Then, the transmission / reception means 15d to 15f in the vertical direction are performed to detect the presence or absence of residual vibration. When one sensing object X1 actually exists as shown in FIG. 5A, data can be received from the horizontal coil and the vertical coil at that position. In this way, the control unit 21 can detect the position of the detection object X by identifying the vertical coil number and the horizontal coil number.

Next, consider the case where there are two detection objects X (X1, X2) as shown in FIG. 5 (b). in this case,
When the horizontal transmitting / receiving means 16a to 16f are switched to operate, the transmitting / receiving means 16b and 16d detect residual vibration from the memory device 17 of FIG. When the vertical transmitting / receiving means 15a to 15f are switched to operate, the transmitting / receiving means 15c and 15e detect residual vibration. In this case, two pieces of detection information are stored in the main memory as shown in FIG. 6B, and the position information of the detection objects X1 and X2 and the individual read data output from each detection object are stored.

In this case, since there are two types of read data in step S19 shown in FIG. 7, step S19 is performed.
In step S20 and S21, the vertical and horizontal positions of the first read data and the second read data are determined. Further, if it is known in advance that there are two detected objects, and if two types of read data are not detected in step S19, it is determined that one of the two detected objects X is in an unreadable position. In step S22, an error signal is generated.

Next, as shown in FIG. 5C, two sensing objects X
A case where 1 and X2 are on the same row or the same column will be described. When the horizontal transmitting / receiving means 16a to 16f in FIG. 1 are operated in sequence, the residual vibrations are detected by the transmitting / receiving means 16b and 16d, respectively. Next, the vertical transmission / reception means 15a
When ˜15f operate sequentially, only the transmitting / receiving means 15c may malfunction. Even in this case, the transmitting / receiving means 15c
A carrier signal having a constant frequency is output from the transmitting coil 13s of the above, but since there are two sensing objects X1 and X2 (memory device 17) at this position, two residual vibrations are superimposed from the receiving coil 13r. Signal is received.

In this case, the receiving coil L3 in FIG. 2 receives the composite residual vibration. For example, the switch SW of one memory device 17 is open and the switch S of the other memory device 17 is
Suppose W is closed. At this time, the receiving coil L3 is affected by the switch SW that is open, and receives the residual vibration even when the other is closed. Since the detection device 18 demodulates the change in the presence or absence of residual vibration as data, if these patterns are disturbed, the data cannot be accurately demodulated. When the two sensing objects X1 and X2 are on the same column or the same row as described above, the detection device 18 and the memory device 17 cannot substantially transmit and receive. Such a state is assumed in step S6 of FIG. 6A and step S15 of FIG. Here, in steps S7 and S16, the horizontal transmission / reception coil number and the vertical transmission / reception coil number when communication is disabled are saved in the main memory.

When one or a plurality of detection objects X are present on the detection panel 23 as described above, as shown in FIG.
The position of each detection object X can be detected by the horizontal transmission / reception means 16 and the vertical transmission / reception means 15 without contact, except when a plurality of detection objects are located in one transmission / reception coil. Then, by discriminating the content of the identification data output from the detected object X, the type of the object can be accurately identified without using the image of the imaging camera. In the present invention, no measuring device constituting the object position recognizing device is provided above the detection panel 23, and there is no need to provide a new instrument above the detection panel 23.

Next, as a second embodiment of the present invention, an example in which the aforementioned object position recognizing device is applied to a game machine (game device) will be described. FIG. 8 is a diagram showing the structure of the dice, in which each face of the regular hexahedron is engraved with "1" to "6". For example, data "6" is printed on the surface marked with "1".
The memory device 17A in which the data is written is built in, and the memory device 17B in which the data "3" is written is built in on the surface marked with 4. Similarly, the surface marked with 2 has a built-in memory device 17C in which data "5" is written. In this way, it is assumed that the sum of the numbers engraved on each surface and the data of the memory device is 7. When the dice 24 rolls on the detection surface 23a in FIG. 3 and stands still at an arbitrary position, the memory device 17 on the side contacting the detection surface 23a of the dice 24 can input / output data to / from the detection panel 23.

When the dice emission unit control unit 35 connected to the control unit 34 operates, the dice Y of each player is mechanically ejected from the dice ejection unit 36. When the two dice Y1 and Y2 that have been thrown out on the detection panel 23 stand still as shown in FIG. 9, the dice position and roll detection unit control means 37, which is a part of the object position recognition device 30, detects the dice position and the roll.

At this time, the memory device 17C holds the number of dice stamped at the mounting position of the memory device 17A, and the identification data thereof is output to the detection device 18 side as residual vibration by opening / closing the switch SW of FIG. It These data are detected by the transmitting and receiving coils 13 or 14 which are close to each other, and as shown in step T3 of FIG. 11, through the dice position and roll detection unit 38 of FIG. 10 and the dice position and roll detection unit control means 37. It is input to the control means 34.

In step T4, the control means 34 uses the estimated value of the claw or half which is input from the push button 32, and the die value (dice or half) actually detected by the dice position and the result detecting section 38. The data is stored in the main memory shown in FIG. 12, and the data is given to the operation comparing means 39. The operation comparing means 39 compares the data and checks for a match or a mismatch. In step T5, if the estimated value and the actual value match, the process proceeds to step T6, and the control means 34 causes the display means 33 to display the hit. If they do not match, the process branches from step T5 to step T7, and the deviation is displayed on the display means 33.

Next, in step T8, the recovery unit 41 of FIG. 9 is moved to the position of the dice Y via the recovery unit control means 40. Then, in step T9, the collecting unit 41 captures the dice Y, and in step T10, the dice Y is returned to the dice ejecting unit 36. Then, in step T11, the dice Y is set in the dice ejecting section 36 so as to be shaken again.

Now, the dice Y shown on the right side of FIG.
2 shows the case where the stationary state is not normal. In this case, data is not transferred to the transmission / reception coil 13 or 14 from any of the memory devices 17 provided in the dice Y2. Therefore, only the position data and the identification data (the number of rolls) of one dice Y1 are input to the control means 34. In this case, FIG.
In the object position recognition processing shown in the flowchart of (b), the number of dice thrown from the dice emitting unit 36 is compared with the number of dice actually detected by the object position recognition device 30, and if they do not match, an abnormal signal is generated. I am trying to do it. In such a case, for example, returning to the roll-out, the two rolls of the dice Y1 and Y2 are again thrown out from the dice ejection unit 36.

In this way, the dice are mechanically thrown out,
It is possible to enjoy a quick game development by automatically determining the result state by the detection panel and electrically collating the determination result with the estimated value in advance. Also, if the person who rolls the dice also corresponds to the identification data stored in the memory device, even if a large number of dice are combined and rolled substantially simultaneously, the result is accurately and rapidly notified to each player. be able to.

Although the detection object is a dice, it can be applied not only to a regular hexahedron but also to a three-dimensional object such as a regular dodecahedron or regular icosahedron. Further, the object position recognition device of the present embodiment can be used not only for game machines that compete for the result of drawing out, but also for shogi, for example. In this case, an identification code indicating the rank is attached to each piece, and when each piece is advanced on a grid, the position data of each piece and the position of the piece are electronically processed to transmit the pattern of the virtuoso battle to a remote place. You can also enjoy playing shogi by computer communication. In addition, data processing can be used to find a method of avoiding a crisis (check). In other words, if you enter your own rules into the program beforehand, you can do the usual game development electronically and use your brain in a deadlocked situation.

Next, an object position recognition apparatus according to the third embodiment of the present invention will be described with reference to the drawings. FIG. 14 is a block diagram showing the overall configuration of the object position recognition device 50 of the third embodiment. In this embodiment, the same terms and signal names as those of the first embodiment use the same terms, and detailed description thereof will be omitted.

In the object position recognizing device 50 shown in the figure, a plurality of transmitting coils 51 and receiving coils 52 are arranged in a matrix at regular intervals. As shown in FIG. 15, the transmitting coil 51 and the receiving coil 52 are arranged in close contact with each other on the lower surface of the mounting plane or the moving plane of the detection object. In this embodiment, the transmission coils 51a to 51j are arranged in the row direction (vertical direction), and the reception coils 52a to 52j are arranged in the column direction (horizontal direction).

Both the transmitting coil 51 and the receiving coil 52 are formed in a long and thin track shape, and the magnetic flux incident area and the magnetic flux generation area are substantially the same. Compared with the first embodiment, the width of each coil is smaller and the number of coils in the row and column directions is larger.

In FIG. 14, each of the receiving coils 52a ...
The receiving means 53a to 53j are connected to 52j. Further, one transmission coil switching means 54 is connected to each of the transmission coils 51a to 51j. Then, the transmission coils 51a to 51j are switched to the transmission coil switching means 54 and driven by the transmission means 55. Transmission means 5
Reference numeral 5 is a means for supplying a current of a carrier signal to one of the transmission coils 51 to generate an AC magnetic flux based on transmission data or a data read command. The receiving means 53 detects the electromagnetic induction signal of the detection object received by the receiving coil 52,
It is means for demodulating the data of the sensing object based on the presence or absence of residual vibration of the signal.

The reception confirming means 56 recognizes which receiving means 53 has operated and the column position of the detection object X and the identification data have been input when the detection object X is located on any of the reception coils 52a to 52j. The information is transferred to the control means 57. The control means 57 outputs a switching control signal to the transmission coil switching means 54 and gives the transmission means 55 a transmission data or data read command. Further, the control means 57 receives the information transferred from the reception confirmation means 56, generates position information of the detected object on the basis of the switching information for the transmission coil switching means 54, and sends the data to the upper device via the upper communication means 58. To output.

Next, the transmitter coil 5 will be described with reference to FIGS.
A detection panel having the built-in 1 and the receiving coil 52 will be described. FIG. 15 is a perspective view showing the appearance of the detection panel 59 connected to the circuit section 50a of the object position recognition device.
The detection panel 59 has a rectangular flat detection surface 59a as in the first embodiment, and the transmission coil 51 shown in FIG.
And the receiving coil 52 are embedded. Sensing object X
1, X2 and X3 are objects that can move freely on the detection surface 59a and have the memory device shown in FIG.

FIG. 16 is a sectional view showing the relationship between the detection panel 59, the detected object X, and the memory device 61. The transmission coils 51a to 52d are arranged so as to be adjacent to each other, and are embedded in such a position that the reception coil 52 is sandwiched by the detection surface 59a. The detectable areas 60 shown by the shaded areas are arranged so as to overlap each other at the boundaries. In this embodiment, the memory device 61 built in the detection object X has the detection surface 59a.
When it comes into contact with, the receiving coils 52 arranged in the row direction receive data from the memory device 61.

The operation of the object position recognizing device 50 of the third embodiment having the above structure will be described. FIG. 17 is an explanatory diagram showing a method of identifying the position and the type of the detection object X when three detection objects X (X1 to X3) are present on the detection panel 59. In FIG. 17A, the detection object X1 is at the intersection of the transmission coil 51c and the reception coil 52d, the detection object X2 is at the intersection of the transmission coil 51c and the reception coil 52g, and the detection object X3 is between the transmission coil 51f and the reception coil 52d. The case at an intersection is shown.

FIG. 18 is a flowchart showing the operation of the object position recognition device 50. In the figure, when the detection operation is started, the number of detected objects X is reset to 0 in step U1, and the process proceeds to step U2. In this step, the switching control signal is output by the control means 57 of FIG. 14, and the transmission coil switching means 54 is operated first. At this time, the transmission coil 51a is first selected, and in step U3, the AC magnetic flux having the first and second duty ratios of the constant frequency is output from the transmission unit 55 and the data read command is transmitted.

In this case, since the sensing object X does not exist on the transmitting coil 51a, the residual vibration is not returned by the receiving means 53a to 53j, and the reception confirmation means 56 determines that there is no reception in the next step U4. . In this case, the process branches to step U5 to switch the transmission coil 51. The operations of steps U3 to U5 are repeated until the reception data is obtained in this way.

Now, as shown in FIG. 17A, when switched to the transmission coil 51c, the receiving means 53d and 53 are received.
The residual vibration is detected from g, and the identification data is reproduced by demodulating the electromagnetic induction signal. At this time, the process proceeds from step U4 to step U6 to increment the detected number. Next, in Step U7, the detected object X (X
1, X2) position and identification data are held, and the information is saved in the main memory.

FIG. 19 shows a memory map of the main memory of the third embodiment, which is provided with areas for storing the number of detected objects, the number of selected coils, and the data of individual detection information. The transmission coil number, the reception coil number, and the identification data unique to the detected object are stored in the storage area of each detection information. Until the operation of all the transmission coils 51 is completed in step U8, the process returns to step U5 and the same operation is repeated. When the operation of all the coils is completed, the detection ends.

FIG. 17B shows the recorded contents of the data in the main memory obtained by such an operation. FIG.
As shown in FIG. 7A, even if the detection objects X1 and X2 are on the same row and the detection objects X1 and X3 are on the same column, reception is performed by the reception coils 53 on different rows. Therefore, it does not become undetectable as in the first embodiment.

Needless to say, the object position recognizing device 50 of this embodiment can be applied to a game machine using dice as in the second embodiment. FIG. 20 is a view showing the structure of the dice Y, and memory devices 61a to 6 in which the numbers "1" to "6" are stored on the respective faces of the hexahedron as in the first embodiment.
1f is built in. In this way, only the memory device 61c on the side that contacts the detection surface 59a of the dice Y can input / output data to / from the detection panel 59. The configuration and the operating principle are the same as the configuration diagram and the flowchart of the second embodiment, and therefore the description thereof is omitted here.

In FIG. 20, one dice Y1 is normally stationary and the other dice Y2 is stationary in an unstable state. In this case, no data is input to the receiving coil 52 from any of the memory devices 61 provided in the dice Y2. Therefore, only the position data and the identification data (the number of rolls) of one dice Y1 are input to the control means 57. In this case, in the process of object position recognition similar to the above-described flowchart of FIG. 13B, the actual number of dice is compared with the number of dice detected by the object position recognition device 50, and if they do not match, an abnormal signal is output. I'm trying to happen.

Next, an object position recognition apparatus according to the fourth embodiment of the present invention will be described with reference to the drawings. FIG. 21 is a conceptual diagram showing the overall configuration of the object position recognition device 70 of the fourth embodiment. In this embodiment also, the same terms as those of the first to third embodiments and the signal names use the same terms, and detailed description thereof will be omitted.

In the object position recognizing device 70 shown in this figure, a plurality of transmitting / receiving coils 71 arranged in the vertical direction and a plurality of transmitting / receiving coils 72 arranged in the horizontal direction are arranged in a matrix at regular intervals. Has been done. As shown in FIG. 22, the transmitting / receiving coil 71 and the transmitting / receiving coil 72 are arranged in close contact with each other on the lower surface of the mounting plane or the moving plane of the detection object, as in the first embodiment. In this embodiment, the transmission / reception coils 72a to 72j are arranged in the row direction and are switched by the first transmission / reception coil switching means 73. The transmission / reception coils 71a to 71j are also arranged in the column direction and switched by the second transmission / reception coil switching means 74.

Both the transmitting and receiving coils 71 and 72 are formed in an elongated track shape, and the transmitting coil and the receiving coil are integrally formed as in the first embodiment. The incident area of the magnetic flux of the receiving coil and the generating area of the magnetic flux of the transmitting coil are substantially the same. Unlike the first embodiment, the transmitting / receiving coil 72 in the column direction is the first transmitting / receiving coil switching means 7
Alternatively, the frequency of the carrier signal can be switched to at least two types by the first frequency switching means 75. The transmission / reception coil 71 in the row direction is also selectively switched by the second transmission / reception coil switching means 74, and the frequency of the carrier signal is switched to at least two types by the second frequency switching means 77. Further, as in the third embodiment, the number of coils in the row and column directions is increased. Such frequency setting is performed for each type of the detection object X, and the resonance frequency of the resonance circuit of the memory device provided in the detection object X is also made to match the frequency of each carrier signal.

The transmission / reception coils 72a to 72j are switched to the first transmission / reception coil switching means 73 and driven by the transmission / reception means 76. Similarly, the transmission / reception coils 71a to 71j are switched to the second transmission / reception coil switching means 74 and driven by the transmission / reception means 78. The first transmission / reception means 76 supplies a current of a carrier signal to the transmission / reception coil 72, changes the duty ratio based on a data read command, detects residual vibration when receiving data, and demodulates identification data of a detected object. Is. Similarly, the second transmitter / receiver 78 supplies a carrier signal current to the transmitter / receiver coil 71 to change the duty ratio based on the data read command, detects residual vibration when receiving data, and demodulates the identification data of the detected object. Is a means to do.

The control means 79 is the transmission / reception coil switching means 7
It is means for outputting a switching control signal to 3 and 74, respectively, and for giving a data read command to the transmitting / receiving means 76 and 78. Further, the control means 79 inputs the information transferred from the transmitting / receiving means 76, 78, and the transmitting / receiving coil switching means 73, 7
4, and position information of the detected object is generated based on the switching information for the frequency switching means 75 and 77, and the higher order communication means 80.
Function to output the data to the host device via.

Next, the detection panel having the transmission / reception coils 71 and 72 built therein will be briefly described with reference to FIGS. FIG. 22 is a perspective view showing the outer appearance of the detection panel 81 connected to the circuit section 70a of the object position recognition device. The detection panel 81 has a rectangular flat detection surface 8 as in the first embodiment.
1a and a transmission / reception coil 71 shown in FIG.
And 72 are buried. Sensing objects X1, X2, X
Reference numeral 3 denotes an object that can move freely on the detection surface 81a, and has the memory device shown in FIG.

FIG. 23 is a sectional view showing the relationship between the detection panel 81, the detected object X, and the memory device 82. The horizontal transmission / reception coils 72a to 72d are arranged so as to be adjacent to each other, and are embedded in such a position as to sandwich the vertical transmission / reception coil 71 with the detection surface 81a. The detectable areas 83 shown by the shaded areas are arranged so as to overlap each other at the boundary. When the memory device 82 built in the detection object X contacts the detection surface 81a, the transmission and reception coils 71 and 72 arranged in the row and column directions transmit and receive data to and from the memory device 82 at different timings.

The operation of the object position recognizing device 70 of the fourth embodiment having such a configuration will be described. FIG. 24 is an explanatory diagram showing a method of identifying the position and the type of the detection object X when three detection objects X (X1 to X3) are present on the detection panel 81. FIG. 25 is a flowchart showing the operation of the object position recognition device 70. When the detection operation is started in FIG. 25, the number of detected objects X is reset to 0 in step V1, and the process proceeds to step V2. In this step, the frequency switching control signal is output by the control means 79 of FIG. 21, and the frequency switching means 75 and 77 first select the frequency f1. Further, the control means 79 operates the transmission / reception coil switching means 73, and the transmission / reception coil 72 is operated in step V3.
Select a. In step V4, oscillation is performed at the frequency of frequency f1, AC magnetic flux having the first and second duty ratios is output from the transmission / reception coil 72a, and the data read command is transmitted.

In this case, since the sensing object X does not exist on the transmission / reception coil 72a, the residual vibration is not returned by this coil, and it is determined in the next step V5 that there is no reception.
In this case, the process branches to step V6 to switch the transmission / reception coil 72. The operations of steps V4 to V6 are repeated until the reception data is obtained in this way.

Now, as shown in FIG. 24 (a), if the resonance frequency of the sensing object X1 is f1 and the resonance frequency of the sensing object X3 is f2, for example, the transmitting / receiving means 76 when switched to the transmitting / receiving coil 72d. The residual vibration at the resonance frequency f1 is detected. The identification data is reproduced by demodulating the electromagnetic induction signal. At this time, the process proceeds from step V5 to step V7, and the detected number is incremented. Next, proceeding to step V8, the column number and identification data of the detected object X1 are held, and the information is saved in the main memory.

FIG. 26 shows a memory map of the main memory of the fourth embodiment, in which the number of detected objects, the selected frequency,
Areas for storing selection coil numbers and data of individual detection information are provided respectively. The transmission / reception coil number, the reception frequency, and the reception data unique to the detected object are stored in the storage area of each detection information. All transmitting and receiving coils 7
Until the operations of Nos. 2 and 71 are completed, the process returns from step V9 to step V6, and the same operation is repeated. In this case, when the switching of the transmitting / receiving coil 72 in the horizontal direction is completed, the control means 79 outputs a switching control signal to the transmitting / receiving coil switching means 74 to switch the transmitting / receiving coil 71 in the vertical direction. Then, the transmission / reception coils 71a to 71j are sequentially operated. When the operation of all the coils is completed, the process proceeds from step V10 to step V11, and the selected frequency is switched from f1 to f2. Thereafter, the same operation as in the case where the selected frequency is f1 is repeated.

By thus preparing a plurality of selection frequencies and providing each sensing object X with a resonance circuit (memory device of FIG. 2) having a different selection frequency, as shown in FIG. Alternatively, even if the detection object X is present on the line, the position thereof can be accurately detected without becoming undetectable.

Needless to say, the object position recognition device 70 of this embodiment can be applied to a game machine using dice as in the second embodiment. The configuration and the operating principle are the same as the configuration diagram and the flowchart of the second embodiment, and therefore the description thereof is omitted here.

[0076]

As described above, the object position recognizing device according to the first, second and third aspects of the present invention has the following effects. (1) Since the position of the sensing object is detected and the type thereof is identified by the electromagnetic coupling method, the influence of ambient light and design restrictions are not imposed, and the degree of freedom in designing the device to be incorporated is greatly improved. (2) Compared with the conventional image processing method, the manufacturing cost can be significantly reduced while maintaining the function of recognizing the position of the object. (3) The space below the moving surface of the sensing object needs to be as small as the thickness of the transmitting and receiving coils.
