Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to, for example, a card quantity reading device for counting the number of telephone cards sold.

[Conventional technology]

A conventional technique will be explained using a telephone card as an example. For example, when selling telephone cards at a counter, the person in charge of sales would store them in a desk drawer, sorting them by design, and then pulling them out and selling them. Therefore, when checking the number of telephone cards sold and the number of cards in stock, the number of telephone cards sold and the number of cards in stock had to be manually counted by price (hereinafter referred to as frequency). [Problem to be solved by the invention] As mentioned above, counting the number of telephone cards sold and the number in stock is done manually, and since there are many kinds of telephone cards, several workers are required to perform one check. However, there was a problem in that it required long hours of work. This invention was made to solve this problem, and provides a device that can accurately and quickly check the number of sold items by strength and type without manually checking the number of sold items and inventory items. The purpose is to [Means for Solving the Problems] A card quantity reading device according to the present invention includes a storage case that stores cards whose end surfaces reflect light and partitions each type with a partition plate having a reflective plate; and a storage case that stores cards whose end surfaces reflect light. A sensor unit includes a first sensor that emits light and receives the reflected light, and a second optical sensor that emits light to a reflecting plate and receives the reflected light, and the sensor unit is housed by a predetermined control signal. a driving means for moving the first sensor along the case; a first waveform shaping means for removing a low frequency component of the output signal of the first sensor and then shaping the waveform to output a first pulse signal; After inputting the output signal and removing the high frequency components of the output signal, the waveform is shaped, and the output signal is sandwiched between two
a second waveform shaping means that outputs a pulse signal with a time width corresponding to the thickness of the rare card as a second pulse signal;
a calculation means for inputting the first pulse signal and the second pulse signal, performing an AND operation, and outputting the result as a third pulse signal; and outputting a control signal for moving the sensor section to the driving means. Then, when the output signal of the second optical sensor reaches a predetermined time width, the third pulse signal is read, the latest pulse period is compared with the previous pulse period, and the presence or absence of a match is detected. It is equipped with a microcomputer that calculates the number of cards from the number of pulses. In addition, the microcomputer moves the sensor section back and forth between the reflectors via the driving means, detects the coincidence and mismatch of each card period on the outgoing trip, calculates the number of cards, and furthermore calculates the coincidence and mismatch of each card period on the return trip. This is to detect the number of cards and calculate the number of cards. Furthermore, if the number of cards and the card cycle do not match when the sensor unit moves back and forth, the sensor unit is moved back and forth a predetermined number of times, and when the number of each card matches and the cycle matches, that number is determined as a normal value. This is what is output. [Function] In the present invention, the microcomputer outputs a control signal to the driving means to move the sensor part along the storage case, and then when the output signal of the second optical sensor reaches a predetermined time width, After reading the reflected light from the reflection plate of the partition plate via the second sensor, a predetermined process is executed, and the sensor section is further moved. Then, the reflected light from the end face of the card is outputted to the first waveform shaping means via the first sensor, and after the low frequency component is removed, the waveform shaped first pulse signal is outputted to the calculation means. do. Further, the output signal of the first sensor is waveform-shaped by removing high-frequency components by a second waveform shaping means, and then converted into a second pulse signal having a time width corresponding to the thickness of the card sandwiched between the partition plates. and is output to the calculation means. The calculation means performs an AND operation on the first pulse signal and the second pulse signal, and outputs the result to the microcomputer as a third pulse signal. The microcomputer reads the third pulse signal and compares the latest pulse period with the previous pulse period,
The presence or absence of a match is detected and the number of cards is calculated from the number of pulses. Furthermore, when the microcomputer moves the sensor section back and forth between the reflectors via the driving means, it detects the coincidence and mismatch of each card period on the outward trip, calculates the number of cards, and further calculates the coincidence and mismatch of each card period on the return trip. Inconsistency is detected and the number of cards is calculated. Furthermore, if the number of cards and the card cycle do not match when the sensor unit reciprocates, the sensor unit is reciprocated a predetermined number of times,
When the numbers of each card match and their cycles match, that number is output as a normal value. [Example] Fig. 1 is a front view of the card quantity reading device of the present invention, in which (1) is the operation section, (2) is the printer/(

The CPU inputs signals and signals (45a), outputs control signals based on commands from the CPU (31), and displays the degree on the display (4B). When the start key (lG) is pressed and the ENTER key (18) is pressed, the card quantity reading device configured as described above sequentially outputs command signals corresponding to the signals from the first stage. Then, the CPU (4B) of the first storage shelf (4) reads whether there is an output signal from the optical sensor (35), and if there is no electrical signal, moves the sensor part to the optical sensor (35) side. A signal is output to the motor control circuit (44). The motor control circuit (44) converts this signal into a desired control signal and outputs it to the driver circuit (43). The driver circuit (43) applies a DC voltage to the motor (42) based on this control signal. Then the motor (
42) moves the sensor section toward the optical sensor (35) (hereinafter referred to as the positive direction). When the light sensor (35) receives input from the sensor section, the emitted light is blocked.
The low level (hereinafter referred to as low level) signal is sent to the CPU (4G
). When the signal from the optical sensor (35) becomes L, the CPU (4g) outputs a movement signal to the motor control circuit (44) to stop the rotation of the motor (42). Then, the motor control circuit (44) outputs a control signal based on this signal to the driver (43). The driver (43) applies a reverse DC voltage to the motor (42) from this control signal, stops the motor (42), puts the sensor section into operation, and rotates the motor (42) to illuminate the sensor section. It is moved toward the sensor (34) side (hereinafter referred to as the opposite direction). FIG. 5, which will be explained below using a timing chart, is a timing chart explaining the operation of the electric circuit section (30). In the figure, (33a) is a reflector detection sensor (33)

detects the light emitted by the
A reflector detection signal (aaa) is output to 39). The amplifier circuit (39) amplifies this signal and shapes the waveform, and then sends the inverted output signal (39a) to the CPU (4
8). When this signal is input, CP IJ (4B>) detects that the sensor unit has come to the position of the first dummy partition plate (20), executes processing to stop the motor (42), and then When the part is moved in the forward direction, the card detection sensor (32) detects the reflected light from the telephone card, and outputs an output signal (32) that converts the reflected light into an electrical signal.
2a) is output to the amplifier circuit (3B). At this time, since the dummy partition plate and the bottom of the partition plate, except for the reflective plate, are coated with black paint, the light emitted from the card detection sensor (32) is absorbed, and the electric signal (32a) is Since it is only a dark current, it cannot be detected as a signal. The amplifier circuit (3B) amplifies this signal (a2a) to a desired degree of amplification and outputs the output signal (36a) to the limiter circuit (37).
) and a voltage hold circuit (40). When the output signal (36a) is input, the limiter circuit (37) cuts the DC component and also filters out noise lower than the card signal. Then, only the signal component is inverted and amplified, and then a limiter is applied to the output signal (37a)
is output to the comparator (38). When the output signal (37a) from the limiter circuit (37) is input, the comparator (38) compares this signal with the reference voltage, sets it to H if it is higher than the reference voltage, and sets it to L if it is lower than the reference voltage, and mixes the output signal (38a). (45). In addition, the input of the voltage hold circuit (40) is equipped with a filter for removing harmonics, and the output signal (38a)
If there is a higher frequency than the card signal contained in the card signal, it is removed, and then the output signal (40a) obtained by inverting and amplifying the output signal (36a) and the output signal (38) of the amplifier circuit (36) are removed.
a) is inverted and amplified, and the output signal (4
0b) is output to the comparator (41). This comparator (41) compares the output signal (40a) and the output signal (40b) of the voltage hold circuit, and if the output signal (40a) is larger than the voltage of the output signal (40b), an H output signal (41a) is generated. is output to the mixer (45).The mixer (45) inputs and mixes these two signals, and outputs the output signal (4) which is NANDed with the signal (41a).
5a) is output to the CPU (4g). Therefore, only the signal between the reflector (20a) and the reflector (22a) can be made valid. FIG. 6 is a flowchart explaining the operation of the card quantity reading device. When the CPU (31) of the operation unit (1) turns on the power switch, it displays the current time on the display (8) (S5).
Then, it is determined whether there is any key input (S8). If there is an input, the pressed key is read (SIO) and the process based on the input of that key is displayed on the display (8) (S1
2). It is determined whether or not the CLR key (17) has been pressed, and if it has been pressed, the process returns to step S5 (914). ENT within 3 minutes unless the CLR key (17) is pressed.
It is determined whether the ER key (18) has been pressed, and if it has not been pressed, the process returns to step S5 and the current time is displayed (S16). If the ENTER key (18) is pressed within 3 minutes, the address corresponding to the input key is read (S18) J
Control is transferred from the UMP table to the processing routine corresponding to the key (S20). Next, this processing routine will be explained. Step S
If the total key (14) is pressed at step 8, the control is transferred to the total routine (8200), and if the frequency set key (13) is pressed, the control is transferred to the frequency registration routine (8100). If the automatic timer key (11) is pressed, the control is transferred to the automatic count registration routine (5400), and if the time adjustment key is pressed, the control is transferred to the current time adjustment routine (3800). Further, if the start key (16) is pressed, control is transferred to a counting routine (8700). There are also error routines and print routines. Next, in step S8, if there is no key input, it is determined whether the timer mode is set, and if the time is not set in the timer, the process returns to step S5 (822). If it is determined that it is a timer mode, it is difficult to determine what kind of timer mode it is.5
23) Display the time of both timer 1 and timer 2 82G) If only timer 2 is set, display the time of timer 2 (82B). Also, if it is timer 1, the timer 1 time is displayed on the display (8
) (S30). Next, it is determined whether each timer time and the current time match, and if so, control is transferred to the counting main routine (S32). this is,
Judged for each timer. Next, when the processing routine described above is completed, the process returns to step S5 (834). FIGS. 7(a) to 7(d) are flowcharts illustrating the operation of the count main routine. If the start key (16) is pressed, the processes from step S5 to step 820 in FIG. 6 are executed, and the count main routine is selected. Then, the CPU (31) outputs the first stage selection address to the communication port, assuming that these commands are for the first stage CPU (411) (8501).
. This command is received by the CPUs of all stages, but since it is the address of the first stage, only the CPU (48) of the - stage must release the reset (5eot), and the CPU of the operation unit (1)
(31) outputs a READY signal that is ready for processing (!3803). The CPU of the operation unit (1) read this (8502)
(31) outputs the address 10 count start command signal to the first stage CPU (48) (8503)
. When this command signal is output, the first stage CPU
(48) sends the BUSY signal indicating that it is being processed to the operating unit (
1) is output to the CPU (31) (S605). This BUSY signal is sent to the CPU (31) of the operation unit (1).
is read (8505), and based on this signal, the processing is output to the display (8) (S507). In this case, it is displayed that the first stage is counting.
8) releases the BUSY signal and executes the process of step 5507 until the READY signal is output (8509
). Also, at this time, the CPU (48) selects a processing routine corresponding to the command from the JUMP table, and transfers control to the counting routine (S607). When the count routine is reached, the used buffer memory is cleared (8615) and a check is performed to see if the shelf is open (S617). Next, it is determined whether there is an electric signal from the optical sensor (35) (5619), and if not, the motor (42) is rotated to move the sensor section in the opposite direction (S621). If it is determined that there is an electric signal, the rotation of the motor (42) is stopped,
Rotate the motor to move the sensor part in the forward direction (
8623). Next, it is determined from the output signal (39a) whether there is a signal from the reflector plate, and if there is no signal, the sensor section is further moved in the forward direction (98
25), if so, output a reversal pulse for stopping the motor and brake the motor (42) (8627). Next, it is determined whether the motor rotation has stopped, and if it has not stopped, the brake is applied again and the process returns to step 5627 (SI329).
. If it is determined in step 5629 that the motor has stopped,
The time width of the output signal (39a) is read (8G31), and it is determined whether the sensor section is at a predetermined position (S633). If it is determined that it is not at the predetermined position, it is determined from the time width whether the sensor unit has gone too far (5835), and if it has not gone too far, the rotation speed of the motor (42) is calculated from that distance, and the motor (42) is rotated a little. to move the sensor section in the forward direction (8837), and return to step 5627. Next, if it is determined in step 5635 that the sensor unit has gone too far, calculate what kind of pulse to output from that distance, apply an appropriate reverse pulse, and move the sensor unit in the opposite direction (S639 ), the process returns to step 5627. This process is executed until the sensor section is at a predetermined position. FIG. 8 is a timing chart explaining the reversal pulse, in which (a) is the reversal pulse width, (b) is the pulse interval, (4
4a) is the first reversal pulse, (44b) is the second reversal pulse, and (44c) is the third reversal pulse. The pulse width (a) and pulse interval (b) are, for example, 3
Assuming that the sensor unit is at a predetermined position in the second time, the relationship shown below is established. Reverse pulse width (a) - 1st reverse pulse (44a)
2nd reversal pulse (44b) < 3rd reversal pulse (44e) Pulse interval (b) - 1st reversal pulse (44a) >
2nd reversal pulse (44b) > 3rd reversal pulse (
44c) In other words, speed up gradually. The same applies to the forward direction. Next, if it is determined in step 5633 that the sensor section is at a predetermined position, the output signal (39a) is read again and its time width is read (8641). Then, it is determined whether the time width is shifted from a predetermined position (3643
). If there is a deviation, the process returns to step 8635. The reverse pulse in this process outputs the reverse pulse shown in FIG. Next, if it is determined that there is no deviation, the sensor unit determines whether the reflection plate (20a) and the reflection plate (22a) have been moved back and forth (9845). In this case, since the sensor part is not reciprocating, it is determined that it is not reciprocating. If it is not reciprocating, calculate the rotation direction (5647) and determine whether it is forward or reverse (9849). In this case, the calculation is made in the positive direction, and the sensor section is moved in the positive direction (S851). Then, the output signal (39a) and the output signal (45a) are read (8653). The reflector junk is determined from the read signal (8657). In this case, it is from the reflector. Then, step 562
7 and executes the processing up to step 8633. At this time, the sensor section has not yet reciprocated, so the process returns to step 5G47. The rotation direction in step 5647 is calculated in the opposite direction, and the sensor section is moved in the opposite direction (S855). Next, in step 5653, the output signal (39a) and the output signal (45a) are read to determine whether there is an output signal (39a) from the reflector. In this case as well, if it is determined that the source is from the reflector, step 56
27 and executes the processing up to step 3643. Then, in step 5845, it is determined that the sensor section has reciprocated. FIG. 9 is a diagram explaining the moving operation of the sensor section, (
20) to (22a) are similar to those shown in FIG. 6 above. This figure shows, for example, a reflector (20a) and a reflector (22a).
This indicates that the count process is not executed if the counter moves back and forth between the two, and then moves in the forward direction after the reciprocation. Further, the error setting number is to perform this reciprocating operation a maximum of three times, and in this case, the counting process is not executed when moving in the forward direction after performing the reciprocating operation three times. If it is determined that the card has gone back and forth, the number of cards in the forward direction and the number of cards in the reverse direction are compared (5eeeo), and it is determined whether the number of cards in both directions is the same (8862). If it is determined that they are the same, the stored error flag of the card is read (8684) and it is determined whether it is 0 (988B). If it is determined that there are no cards, it is determined whether the number of cards is 0 (8688), and if it is 0, it is stored as 0 in the buffer memory (9670). In this case it is 0. Next, if it is determined that there are enough cards, the counted number is stored in the store memory (8672). Then, it is determined whether the 10 section count is finished (S674).
. If not completed, the output signal from the sensor unit is not read (887B) and the process returns to step 5847. Next, if it is determined in step 5B62 that they are not the same, the set number of round trips at the time of error is read (SCH3). In this case, it is assumed that it is set to three times. Next, it is determined whether the round trip has been made three times (561112), and if it is three or more times, error processing is executed (8884). If the process has not returned three times, the process returns to step 5647. Next, data is initialized to count cards (8690), and the output card signal is stored (S69).
2). Next, it is determined from the cycle of this card signal whether there are 4 or more cards (8694), and if it is determined that there are 4 or more cards, the cycle of the 4th card is compared with the cycles of the 3rd and 2nd cards,
The result is stored (889B). Next, the cycle of the third card signal is compared with the cycle of the second card, and the result is stored (869g). Furthermore, compare the period of the fourth card and the period of the third card (870
0). FIG. 10 is a diagram explaining reading of card signals, (45b) is the first card signal, (45c) is the second card signal.
The signal of the third card, (45d) is the signal of the third card,
(45e) is the fourth card signal. This figure shows the first and second output signals (45a). For example, if there is one telephone card, one
The second card signal (45b) is memorized, and the output signal (45a) when the sensor section moves in the opposite direction is the falling edge to the second falling edge of the first card signal (45b). Compare the time width (hereinafter referred to as card cycle). This is the third card signal (45d
). Next, read each stored comparison result (S702)
, determine whether there are different results for card cycles (97
04). If there is a different period, the error flag is stored (8708), otherwise the process returns to step 5653. Next, if it is determined in step 5694 that there are not more than four sheets, the process returns to step 5653. Next, if it is determined in step 5674 that the 10th section has ended,
The total number of cards in column A is displayed on the frequency display (4B) (8712). Furthermore, if a counting error occurs even after reciprocating the number of cards between the partition plates three times, the number of cards that caused the counting error is displayed. Then, step 8 counts the cards in column B.
Executes based on the processing from step 615 to step 5712 (
8713). Next, after displaying the desired result on the degree display (46), BU
Release SY and confirm that the count has ended by pressing the operation unit (1).
The first stage CPU (48) is notified.
) becomes READY (8715). When the READY signal is output, the CP of the operation unit (1)
U (31) determines that the READY signal has been output in step 5509, reads the signal (8511), and CPU (31) of operation unit (1) sends the addressee data collection command signal to CPU (4g). Output (S51
3). When this command signal is output, the −th stage CP
U (4g) outputs the BUSY signal being processed (S717), and sequentially outputs the count value between the partition plates to the CPU (3υ) from the store memory (S719).
). Then, the operation unit (1) (7) CPU (31) reads the BUSY signal (351B) and then reads the output count data (9518). After the data has been completed, the CPU (31) monitors the number of data (S520). The data collection command mentioned here returns one section of count data for each command. When data collection is completed, the CPU (31
) outputs a command signal to cause the second shelf (5) to perform counting, executes the counting process described above, and collects data (S522). Next, when the second stage is completed, the third stage will be executed 8524),
The fourth stage is executed (8526). When the first to fourth stages are completed, the results are output to the printer and printed (852g). FIG. 11 is a flowchart illustrating the frequency registration main routine. For example, suppose that the telephone cards in the first column A and B are worth 500 yen, and the frequency is 50 degrees, and the CPU of the operation unit (1) Assume that (31) is already memorized. Furthermore, the second step is 1500 yen and the number is 105 degrees, the third step is 3000 yen and the number is 320 degrees, and the fourth step is 50 degrees.
000 yen, and each is memorized as a 540-degree loss. When the frequency set key (15) is pressed, the processes from step S5 to step 320 in FIG. 6 are executed. In this case, set the frequency to be stored in step S12,
If you press the ENTER key (18) and it appears,
Also, the CLR key (17) is not pressed, and the ENTER key (
18) is pressed in step S9, the registered frequency in column A of the first row is displayed, and control is transferred to the frequency registration main routine. When the control is transferred to the power registration main routine, the stored power in column A of the first row is displayed (31 (11). Next, it is determined whether the power set key (13) has been pressed and Then, the process returns to step 9101 and displays the stored power of column A (8102).Next, if it is determined that the power set key (15) has been pressed, the stored 50 degree of column A is displayed.
