DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a payment meter, and more particularly to a payment meter for stamp duty, postage, etc.

An object of the present invention is to provide a payment meter that has a much simpler structure than a conventional payment meter that is mechanically interlocked. In other words, by configuring the control mechanism using a microcomputer, the configuration can be simplified without using complicated mechanical linking means as in the prior art.

Another purpose is that the normal use of a microcomputer in the control mechanism would destroy its memory in the event of a sudden power outage or electrical damage, making it unsuitable for use as a payment instrument. Although this method has some drawbacks, the aim is to overcome these drawbacks.

In order to achieve the above-mentioned object, the present invention provides a stamp duty, postage, etc. payment instrument in which a plurality of letter rings fixed by a locking means protrude from the circumferential surface, and a stamp is connected to a drive mechanism by a one-turn clutch. A numeric setting dial that engages each character ring of the drum and stamping drum and rotates each character ring is mounted on a swing frame, and the swivel frame can be operated by swinging from outside the machine frame to set the number setting dial. is connected to each character ring of the stamping drum, and the number setting dial is swung so that it can be rotated from outside the machine. A set amount switching mechanism is provided with a locking means for releasing the lock, and a number display wheel is provided so as to be rotatable by a fixed angle by a rotating means, and the number display wheel has a number switch that converts displayed characters into electrical signals. a total paid stamp amount display mechanism and a remaining amount display mechanism, which are arranged in parallel, and a rotation confirmation rocking plate provided to swing by engaging with an engagement pin connected to the stamp drum at the initial stage of rotation of the stamp drum. and a pair of drum rotation confirmation mechanisms each consisting of a swinging holder that locks and holds the swinging plate in a swung position as the stamping drum rotates, and releases this holding in response to a lock release signal. When the paper is positioned in the insertion slot of the machine frame, a start signal is issued, and this start signal compares the set amount with the remaining amount, and only when the remaining amount is larger, activates the one-turn clutch, and rotates the drum rotation confirmation mechanism. The amounts displayed on the cumulative payment amount display mechanism and the remaining amount display mechanism are updated using the signal generated by the rocking of the confirmation rocking plate,
The present invention is characterized by comprising a control mechanism that sends a lock release signal to each drum rotation confirmation mechanism after each update confirmation.

A stamp drum 10 having a payment stamp 111 on its circumferential surface that allows the amount of tax to be paid to be changed is mounted on a shaft within the case above the paper guide plate 4.

The payment stamp 11 is arranged on the circumferential surface of the stamp drum 10 and is formed by engraving on a curved metal plate. has.

As shown in FIG. 7, the payment amount stamp 12 is constructed by independently rotatably disposing three character wheels 14 on a shaft 13 that is mounted between the side plates 10A of the stamp drum 10.

Each of these character wheels 14 has an integrally formed character wheel rotation gear 15 on the side surface, and this character wheel rotation gear 15
Similarly, a wheel transmission gear 17 rotatably disposed on a shaft 16 mounted on the side plate 10A is meshed with the shaft 16.

The character wheel rotation gear 15 on the side surface of the character wheel 14 has ten teeth. Then, the character wheel locking lever 18 is engaged with the character wheel rotating gear 15. The character ring locking lever 18 is used to lock the character ring 14 when the amount displayed on the character ring 14 exactly matches the proper position of the payment stamp 11. 18A is elastically locked in the recess between the teeth of the wheel rotation gear 15 by a coil spring 19.

This wheel locking lever 18 is for prohibiting the displayed amount from being changed except by a switching operation which will be described later, and for this purpose, it has the following wheel locking lever locking means 20. The locking means 20 is composed of a locking lever 21 and a locking lever 22.

The number setting dial 34 is a dial having a regular decagonal cross section with each side concave in a substantially arc shape, and numbers from 0 to 9 are sequentially displayed one by one at the center of each side.

The payment amount stamp setting means 31 is normally on standby at a position where the numeric display of the numeric setting dial 34 can be seen from the payment amount display window 5 provided on the top surface of the case 1, and when the payment amount stamp setting means 31 is swung to set the payment amount. When the setting gear 35 meshes with the wheel transmission gear 17, the cutout groove 7A of the dial rotation recess 7 provided on the upper surface of the case 1
A part of the numeric setting dial 34 is exposed and can be rotated. Incidentally, during this swinging, the setting control pin 38 provided protruding from the frame 33 engages with the lock holding lever 22.

Therefore, as the setting knob body 41 slides, the swing arm 39 swings and the pivot pin 45
The lock holding lever 22 swings the lock control lever 44 through the lock control pin 44A and engages the lock control pin 44A.
The number setting dial 34 can be rotated by swinging the numeral setting dial 34.

Next, the stamp drum rotation mechanism 50 will be explained. As shown in FIGS. 11 and 12, a drum gear 51 fixed to the shaft of the stamping drum 10 is connected to an intermediate drive gear 60 connected to the motor 8 via a one-turn clutch 52. As shown in FIGS. A paper such as a tax document is inserted onto the paper guide plate 4 of the case 1, and the light emitting elements 10 are arranged at the upper and lower parts of the inner part of the paper guide plate 4.
When this paper is located between the light receiving element 1 and the light receiving element 102, the light receiving element 102 emits a paper detection signal. Based on this paper detection signal, the control mechanism 100 (described later) activates the clutch solenoid 53 of the one-turn clutch 52.
Set to ON. Due to this ON, the drum shaft 10B is 1
During this one rotation, the payment stamp 11 comes into contact with the ink roller 27, ink is applied to its surface, and it works together with the platen roller 28 to stamp the impression of the payment stamp 11 on the paper. .

The drive of the motor is transmitted to the clutch drive gear 54 via an intermediate drive gear 60. A clutch driven gear 55 is arranged side by side of the clutch drive gear 54 so as to be rotatable with respect to the clutch drive gear 54, and a clutch driven gear 55 is attached to the side of the clutch driven gear 55 and is fixed to the clutch drive gear 54. A ratchet wheel 56 having an integral relationship is projected. That is, a clutch driven gear 55 is rotatably disposed between a clutch drive gear 54 and a ratchet wheel 56, which are in an integral relationship. A ratchet locking lever 57 that is locked to a ratchet wheel 56 is pivotally connected to the outer surface of the clutch driven gear 55 by a pivot pin 61, and one end of the ratchet locking lever 57 is attached to the outer surface of the clutch driven gear 55. The other end of the coil spring 62 is fixed to a latching pin 55A protruding from the latching pin 55A.

Furthermore, a rocking body locking lever 59 that engages with the control rocking body 58 is provided. Rocking body locking lever 59
is to restrict the rocking of the control rocking body 58 and release this restriction by the rocking of the clutch solenoid 53.

In addition, the control rocking body 58 and the rocking body locking lever 59
The other ends of coil springs 64 and 65, one end of which is locked with a locking pin 2B protruding from the machine frame 2, are hooked to. The coil spring 64 of the control rocking body 58 is arranged so that the ratchet wheel locking body engaging portion 58B is always pulled outward, and the coil spring 65 of the rocking body locking lever 59 is arranged so that the ratchet wheel locking body engaging portion 58B is always pulled outward. The plunger 53A is arranged so as to be pulled in the opposite direction to the direction in which the plunger 53A moves.

Therefore, the motor 8 is normally operated as shown in FIG.
Even if the driving intermediate gear 60 connected thereto rotates, the clutch driven gear 55 does not rotate, and neither does the stamping drum shaft 10B. And the control mechanism 100
The clutch solenoid 5 is activated by a stamp signal from
3 is excited and swings the swinging body locking lever 59. Due to this swinging of the swinging body locking lever 59, the control swinging body 58 is released from swinging with the swinging body locking lever 59 and is swung by the coil spring 64. This swinging releases the engagement with the ratchet wheel locking lever 57, and the ratchet wheel locking lever 57 is swung by the coil spring 62 and locks with the ratchet wheel 56. The clutch driven gear 55 and the clutch driving gear 54 are linked by the engagement of the ratchet locking lever 57 with the ratchet 56, and the clutch driven gear 55 rotates. and,
When the clutch driven gear 55 approaches the end of one rotation,
The control oscillating body 58 is oscillated by the engagement pin 55B, and the clutch solenoid 53 is returned to its pre-excitation state. By this return, the engaging portion 57B of the ratchet locking lever 57 that has been rotated comes into contact with the engaging portion 58B of the control rocking body 58, and this contact causes the ratchet locking lever 5
7 swings and is disengaged from the ratchet wheel 56, so that the clutch driven gear 55 completes its rotation after one rotation.

A cumulative payment amount display window 5 and a remaining amount display window 6 for the set amount are provided on the top surface of the case 1. and,
From these windows 5 and 6, a payment amount display mechanism 70
and the remaining amount display mechanism 80 for the set amount.

As shown in FIG. 15, the payment amount cumulative display mechanism 70 is composed of a fixed display section 71 that displays 0 for the 1 to 10 digits, and the digits for the 100 to 1000 digits are equivalent and independent digits. It is composed of a display unit 72, and the digits from 100,000 to 100 million are composed of a 4-digit display unit with a carry function, that is, a 4-digit integration counter 73.

In addition, the remaining amount display mechanism 80 for the set amount is the 16th
As shown in the figure, the ones to tens digits are constructed by a fixed display unit 81 displaying 0, and the hundreds to ten million digits are each constructed by equivalent and independent digit display units 82.

The digit display units 72 and 82 are shown in FIG.
As shown in FIG. 8, a display base 74, a number display foil 75 that is pivoted on the display base 74 and displays numbers 0 to 9 on its circumferential surface, and a number display foil 75
An intermittent rotating gear 76 having 10 teeth is integrally disposed in the intermittent rotating gear 76, and this intermittent rotating gear 76 is rotated by one solid number by the excitation of the number feed solenoid 77 and the elastic force of the coil spring 78. Intermittent feed lever 79
It consists of

The tip of the intermittent feed lever 79 has a forked shape, and when the number feed solenoid 77 is not energized, the claw 79A at the lower end enters the recess between the teeth of the intermittent rotation gear 76, and the number display wheel 7
5 is held unrotatably at a specific position.

Then, by energizing the numerical feed solenoid 77, the intermittent feed lever 79 is swung, and the claw 79A at the lower end escapes from the intermittent rotating gear 76, and the claw 79B at the upper end moves above the upper tooth of the intermittent rotating gear 76. By pushing the tooth surface, the intermittent rotating gear 76 rotates by about 1/2 or more of the angle at which the teeth are arranged. Next, by stopping the excitation of the number feed solenoid 77, the coil spring 78
As a result, the intermittent feed lever 79 returns to its original position, the claw 79B at the upper end escapes upward, and the claw 79A at the lower end comes into contact with the intermittent rotating gear 76. At this time,
Since the intermittent rotating gear 76 has already rotated a little more than 1/2 of the angle at which the teeth are arranged, the claw 79A at the lower end pushes against the inclined surface of the recess on the left side of the recess in which it was locked.
Rotate the number display wheel 75 counterclockwise. In other words, in one stroke of energizing the number feed solenoid 77 and locking it, the number display wheel 75 moves 1/
It will rotate 10 times and switch by one.

And the intermittent rotating gear 7 of the numeric display wheel 75
A display base 75A on which a coded pattern surface of display numbers is formed is fixed to the side opposite to the side where the number display foil 75 is disposed. These display bases 75A and sliding contacts 75B
A kind of numerical switch 75C is formed by these.
Therefore, the electric signal corresponding to the number displayed on the display wheel 75 is obtained by the numerical value switch 75C.

The first four digits of the payment amount cumulative display mechanism 70 use the four-digit accumulation counter 73 as described above.
This accumulation counter 73 is constructed by connecting each number display wheel 75 with a carry gear 73A. Then, when a carry occurs, the cumulative carry solenoid 7
The numeric display foil 75 that displays the 100,000 digit by energizing 3B once is the same as each numeric display foil 7 described above.
Similarly to 5, it rotates 1/10, and when changing from 9 to 0, the number display wheel 75 that displays the adjacent million digit is rotated 1/10 by the action of the carry gear 73A.
It is something that is rotated.

The control mechanism 100 is composed of a microcomputer, and controls each mechanism according to a program installed in advance. This microcomputer controls all mechanisms and is also capable of storing necessary data, but if this memory is destroyed due to an accident such as a fluctuation in the power supply, it will not be used as a payment instrument for stamp duty, etc. This is an unavoidable drawback.

Therefore, a special mechanical storage device is provided to prevent data on the set amount and remaining amount from being lost due to fluctuations in the power supply, etc. Therefore, with this mechanical storage device, even in the event of an accident such as a power outage during stamping, it is possible to prevent data during stamping from being lost. In the device of the present invention, such a mechanical storage device includes a stamping drum rotation confirmation mechanism 90, a cumulative payment amount display mechanism 70 for storing and displaying the cumulative total of payment amounts as described above, and a storage amount displaying mechanism 70 for storing and displaying the cumulative total of payment amounts as described above. There is a set amount balance display mechanism 80 that stores and displays the balance amount.

As shown in FIGS. 13 to 14, the stamp drum rotation confirmation mechanism 90 includes a rotation detection plate 91 fixed to the stamp drum shaft 10B and a rotation detection groove 91A formed in the rotation detection plate 91. A rotation confirmation swing plate 93 that swings by engaging with the sensor 92 and an engagement pin 91B formed on the rotation detection plate 91.
A swing holder 94 is slidably disposed on the machine frame 2 via a pivot pin 94A to maintain the swing of the rotation check swing plate 93, and It is composed of a swing detection sensor 95 that detects.

The engagement between the rotation confirmation rocking plate 93 and the swinging holder 94 is achieved by forming a locking step 93A on the rotation checking swinging plate 93 and also forming a locking step 93A on the swinging holder 94.
A locking pawl 94A is formed to lock the locking step 93A and the locking pawl 94A. The swinging holder 9 is configured such that the locking pawl 94A always locks with one of the step portions of the locking steps 93A.
A coil spring 97 is disposed between 4 and the machine frame 2. Further, a display completion solenoid 96 is connected to the other end of the swinging holder 94 to release the locking state of the rotation confirmation swinging plate 93 when the swinging plate 93 swings.

Note that two sets of rotation confirmation swing plates 93, swing holders 94, and swing detection sensors 95 are provided, and these two sets of rotation check swing plates 93, swing holders 94,
The swing detection sensor 95 is separately connected to the total payment amount display mechanism 70 and the remaining amount display mechanism 80, respectively.

Next, the operations of the stamping drum rotation confirmation mechanism 90, the cumulative payment amount display mechanism 70, and the remaining amount display mechanism 80 will be explained. In response to the stamping drum rotation signal from the control mechanism 100, the clutch solenoid 53 of the one-turn clutch 52 is energized, and the stamping drum shaft 10B starts rotating. Due to this rotation, the rotation position detection groove 9 of the rotation detection plate 91 fixed on the left outer surface of the stamping drum 10
1A escapes the rotation detection sensor 92, a home position signal is generated, and the control mechanism 100 turns off the clutch solenoid 53. but,
Since the clutch solenoid 53 is still mechanically connected, the stamping drum 10 receives the driving force from the motor 8 and rotates once. When the stamping drum 10 starts rotating, the engagement pin 91B of the rotation detection plate 91 pushes up the lower end of the rotation confirmation swinging plate 93 and swings, so the swinging detection sensor 95 detects the swinging and starts the stamping drum rotation. Issue a confirmation signal. The rotation confirmation swing plate 93 is held in its swing position by being locked by the swing holding plate 94.

This rocking operation of the rotation confirmation rocking plate 93 and the accompanying operation of generating the seal drum rotation confirmation signal of the rocking detection sensor 95 are performed prior to the time when the impression of the payment stamp 11 is actually stamped. However, since the stamping drum shaft 10B is provided with a bearing (not shown) as a one-way rotation means, the operation is irreversible, and the stamping drum rotation confirmation signal always indicates that the printing operation has been performed. This guarantees that

When the control mechanism 100 receives the seal drum rotation confirmation signal, first, the remaining amount data is inputted from the display board 75A of the remaining amount display mechanism 80 through the sliding contact, and the number setting dial 3 of the payment amount stamp setting mechanism 30 is input.
A remaining amount display pattern is generated by determining a new remaining amount using the difference in set amount data from a numeric switch 49 that converts the displayed digits of a numeric setting dial 34 into an electric signal, which is connected to the numeral setting dial 34 via an intermediate gear 48.

Next, the control mechanism 100 energizes the number feed solenoid 77 to turn the number display wheel 75 in order to match the remaining amount display pattern with the remaining amount data of the number switch 75C arranged in parallel with the number display foil 75 of the remaining amount display mechanism 80. The remaining amount display mechanism 80 rotates to display new remaining amount data.

Similarly, the payment amount cumulative display mechanism 70 also displays new cumulative data. That is, when the seal drum rotation confirmation signal is received, the cumulative data is inputted from the numerical switch 75C of the payment amount cumulative display mechanism 70, and the set amount data is inputted from the numerical switch 49 of the payment amount stamp setting mechanism 30. A cumulative total display pattern is generated by calculating a new cumulative total using the sum of the data. Next, the braking mechanism 100 excites the numeric feed solenoid 77 to display the numeric value in order to match this cumulative total display pattern with the remaining amount data of the numeric switch 75C arranged in parallel with the numeric display foil 75 of the payment amount cumulative display mechanism 70. The wheel 75 is rotated to display new cumulative data on the payment amount cumulative display mechanism 70.

When the new remaining amount data and cumulative total data have been displayed, the control mechanism 100 energizes the display completion solenoid 96 connected to the swing holder 94 of the stamp drum rotation confirmation mechanism 90. Due to this excitation, the solenoid 96 attracts the plunger 96A, swings the swing holder 94, and rotates the rotation confirmation swing plate 9.
3 is returned to the position before the stamp drum 10 started rotating. In other words, this rotation confirmation rocking plate 93 mechanically remembers that the seal drum 10 has stamped, and is returned to its original position after the correct display has been made, so even if the power is turned off at any point, the incorrect display will not occur. This guarantees that this will not happen.

The reason why two sets of these stamp drum rotation confirmation mechanisms 90 are provided and these mechanisms 90 are separately linked to the remaining amount display mechanism 80 and the total paid amount display mechanism 70 is as follows. In other words, if the power is turned off when only the remaining amount has been displayed, the rotation confirmation swing plate 93 of the stamp drum rotation confirmation mechanism 90 connected to the payment amount cumulative display mechanism 70 will be moved to the engagement pin 91B of the rotation detection plate 91. The control mechanism 100 is held by the swing holder 94 while being swung by the holder 94, and maintains that state.
The fact that the cumulative total has not yet been officially displayed can be detected by the swinging of the rotation confirmation swinging plate 93. In this case, the control mechanism 100 inputs the three digits from the hundreds digit to the ten thousand digit of the correct balance from the balance display wheel 75 (the last two digits from the ones digit to the tens digit of the balance are "0"). '' and are not used in data calculations, so the last two digits from ones place to tens place are omitted.) Next, this input data is subtracted from 1000 and this value is displayed on the cumulative total display wheel 75. This is done based on the fact that if you add up the three digits from the hundreds digit to the ten thousand digit for each of the remaining amount and cumulative amount, it will always be "000".

Therefore, since the mechanical storage means of the stamping drum rotation confirmation mechanism 90, the remaining amount display mechanism 80, and the total payment amount display mechanism 70 is adopted, there is no need to rely on electrical storage means, and therefore there is no need to rely on semi-permanent storage means. It has a function that allows accurate data to be maintained at all times, regardless of power failure or sudden electrical damage within the device.

The set amount setting mechanism 110 includes a seal guard cover 112 having a seal guard lock 111 that is locked with a seal guard key 111A kept at the tax office;
It is protected by a seal plate 113 disposed within this seal guard cover 112 and is disposed within the case 1.

The case 1 consists of an upper case 1B and a lower case 1C, and the lower case 1C is attached to the machine frame 2 with mounting screws 9.
is fixed. And upper case 1B is machine frame 2
The locking piece 1D is locked in the locking hole 2C formed in the front part of the lower case 1C.
3 is fixed and arranged.

The sealing plate 113 is attached to the rear lower edge of the upper part 1B via a hinge portion 113A, and the sealing plate 113 can be opened and closed by this hinge portion 113A. The sealing plate 113 is provided with a sealing screw 114 that penetrates the sealing plate 113 and the lower case 1C and fixes the two. Seal screw 11
4 are arranged in parallel on the sealing plate 113, and a through hole 114A is bored in the upper part of the sealing screw 114 in a direction perpendicular to the center line of the sealing screw 114.
After tightening the sealing screw 114, one sealing wire 115 is passed through the through hole 114A, and then this sealing wire 115 is fixed with a sealing member 116 for sealing.

Further, behind the seal plate 113, there is a two-digit set amount setting switch 117 and a set switch 11 for making the control mechanism 100 read the set amount set in the set amount setting switch 117.
8. Set amount setting switch 117
uses a numeric switch that converts the displayed number into a BCD code, etc.

When setting, the set amount is displayed on the remaining amount display mechanism 80 via the control mechanism 100 by adjusting the display number of the set amount setting switch 117 to the set amount and then pressing the set switch 118. Incidentally, the lower digit of the set amount setting switch 117 is designed to display the hundred thousand digit. Therefore, the set amount will be displayed in the 100,000 and 100,000 digits of the remaining amount display mechanism 80. Furthermore, even if there is less than 100,000 yen remaining at the time of setting, it is possible to set the set amount.
For example, if you have a balance of 98,600 yen and set it to 1,200,000 yen, the balance display mechanism 80 will display the following:
It will be 1298600 yen.

The control mechanism 100 reads the set amount data from the numeric switch 49 of the payment amount setting mechanism 30, reads the remaining amount data from the numeric switch 75C of the numeric display wheel 75 of the remaining amount display mechanism 80, and stamps only when the remaining amount data is large. A signal is issued to activate the clutch solenoid 53 of the one-turn clutch 52. This operation causes the stamp drum 10 to rotate once and stamp a predetermined payment stamp 11. Further, if the balance data is smaller than the set amount data, the clutch solenoid 53 is not energized and a new seal is not affixed.

As described above, the control mechanism 100 is constituted by a microcomputer, and the various operations described above are performed according to the flowcharts shown in FIGS. 19 to 27. The electrical safety mechanism includes 12V system protection means, power down protection means, CPU runaway monitoring means, malfunction detection means, etc.

The 12V system protection means is intended to prevent the 12V system, which is the power source for driving the clutch and display solenoids, from malfunctioning. In other words, the power source for driving the clutch and display solenoid is
It is supplied from the 12V system, and if this supply is performed before or after the CPU starts operating, there is a high risk of malfunction. Therefore, in order to prevent malfunction, the photocoupler 103 and the transistor TR1,
By the circuit of TR2, AC100V is ON and CPU
The circuit configuration is such that the 12V system is supplied only when the 5V DC supplied to the system is ON (see Figure 29).

The power down protection means is such that when the AC100V voltage drops, the Cds of the photocoupler 103 detects this and generates a power down signal, and this voltage down signal causes the CPU of the control mechanism 100 to control the display foil 75, etc. that is being commanded in advance. The structure is such that the drive of the solenoid is stopped. still,
The above operation is possible because the 5V power supply for the CPU system is maintained for a certain period of time by the capacitor in the power supply even if the voltage of the 100V AC power supply drops.

The CPU runaway monitoring means is configured as follows.
In other words, when the CPU is executing the program according to the normal procedure, an L signal is generated from Bit 7 of IC1 at approximately equal intervals, and this signal is generated by the small capacitance connected to the base of the monitoring transistor. The monitoring transistor is always OFF to keep the capacitor discharged. If the CPU deviates from the normal program and goes out of control, the capacitor will no longer be discharged by the CPU's command, and as a result, the base voltage will rise, and the transistor will eventually turn on. As a result, the ALL signal becomes active, the warning light lights up, transistors TR3 and TR4 turn off, and the 5VC power line that is supplied to the output control system such as the solenoid is cut off, preventing malfunctions in each output system. To prevent.

The malfunction detection means detects malfunction or malfunction in the following cases, and in the case of malfunction, it flashes a warning light and issues a warning, and in the case of malfunction, it activates a self-holding relay (LDK) installed in the circuit. to prohibit all operation of this instrument. Note that in the case of an erroneous operation, this warning will be cleared by normal operation. In addition, in the event of a malfunction, it can be resolved by pressing a reset switch 119 provided at the back of the sealing plate 113. Therefore, in case of malfunction, the seal must be cut to release it.

The present invention can include the following aspects for detecting this malfunction.

When the stamping drum 10 is not located at the home position even after 3 seconds have passed since the power was turned on.

When the balance and cumulative total have been displayed and the total from the hundreds digit to the ten thousand digit is not "000".

When the balance is not displayed within 10 seconds.

When the stamp drum 10 does not start rotating within 10 seconds.

When the swing detection sensor 95 does not activate the stamp drum rotation confirmation signal to each display mechanism 80, 70 for the remaining amount or cumulative amount within 10 seconds after the stamp drum starts rotating 10 times.

Within 10 seconds after the stamping drum starts rotating 10 times, the remaining amount data in the control mechanism 100 and the remaining amount display mechanism 80
When the remaining amount data from the display foil 75 does not match.

When the stamping drum 10 does not return to the home position within 10 seconds after the stamping drum starts rotating 10 times.

When the cumulative total was not displayed when the power was turned on, but the cumulative total was calculated from the remaining amount within 10 seconds and the cumulative total could not be displayed.

When the remaining amount was not displayed completely when the power was turned on, or when the remaining amount could not be calculated and displayed from the cumulative total within 10 seconds.

In addition, in the case of detecting malfunction, the present invention
An example of this is an attempt to affix a seal when the remaining amount is less than the set amount.

Furthermore, as another mechanical safety protection mechanism, the frame 3 is designed to prevent the swinging means 40 of the payment amount stamp setting mechanism 30 from operating while the stamping drum 10 is rotating.
A lock pin 120 is disposed in a lock groove 33A formed at the lower part of the lock pin 120, and a lock solenoid 121 is connected to the lock pin 120. When the solenoid 121 is energized, the lock pin 120 is moved within the lock groove 33A and stamped. While the drum 10 is rotating, the payment amount stamp setting means 31 is locked to be held in a non-setting position, and this lock is released.

In addition, in the meter of the present invention, a confirmation stamp (not shown) may be placed side by side on the stamp drum 10 so that a confirmation stamp (not shown) can be stamped at the same time as the payment stamp 11, if necessary.
This confirmation mark can be fixed to the stamp drum 10 with a screw, or can be fixed to the stamp drum 10 with a knob 12 on the top of the case 1.
3, and by swinging this knob 123, the confirmation mark is connected to the stamp drum 10 through a clutch means (not shown).

Next, the operation of the device of the present invention will be explained. This operation can be roughly divided into the operation when setting at the tax office and the operation when used by the user.

The operations at the tax office are as follows. First, the seal guard cover 112 is opened downward using the key 111A kept at the tax office. Next, the sealing wire 115 inside is cut, the two sealing screws 114 are rotated, and the sealing plate 113 is removed. Then, after turning on the power, set the displayed number on the set amount setting switch 117 to the set amount, and then turn on the set amount setting switch 117.
Press 18. By this operation, the set amount is displayed on the remaining amount display mechanism 80 via the control mechanism 100 and is mechanically stored. Thereafter, the seal is sealed and the seal guard cover 112 is locked in accordance with the reverse procedure of the unsealing operation.

The user operates as follows. First, insert and turn the power key 124 held by the meter administrator to turn on the power, pull the knob 41A of the setting knob body 41 at the top of the case 1 toward you, and turn the numeric setting dial 34 to set the set amount. do. Thereafter, the knob 41A is pushed back, and after confirming visually through the confirmation window 125 whether the set amount has been set reliably, the paper such as a tax document is inserted to the back of the paper guide plate 4 of the case 1. When the paper reaches the back, by releasing your hand, the payment stamp 11 is automatically stamped and the paper is discharged to the front.

Thereafter, by repeating the same process, the remaining amount display mechanism 8
Payment stamp 11 until the remaining amount displayed as 0 becomes 0 or the set amount becomes larger than the remaining amount displayed.
can be stamped.

In the figure, 126 is a date stamp operation door for rotating and setting the date on the date stamp, 127 is an operation enable indicator light that indicates that the payment stamp can be stamped, and 12
Reference numeral 8 is a warning light that flashes to issue a warning in the event of an erroneous operation, and 129 is a removal knob for replacing the ink roller.

Since the present invention is constructed as described above, it can be provided with a relatively simple construction without using a mechanically complicated mechanism unlike conventional payment meters. Moreover, since it is controlled by a microcomputer, it can easily handle complex processing. Furthermore, because it ultimately uses a mechanical storage means without relying on memory stored by a microcomputer, the stored contents will not be lost even if the power supply fluctuates during use or the power is turned off semi-permanently, and the stamp tax can be saved. Alternatively, it can be made highly reliable as a payment meter for postage, etc.

That is, it consists of a plurality of wheels 14 fixed by a locking means 20 protruding from the circumferential surface, and a one-turn clutch 5.
Since the stamping drum 10 is connected to the drive mechanism in step 2 and has a one-way rotation means, the control mechanism 1
By operating the one-turn clutch 52 in response to a stamp signal of 00, the control mechanism 10 is reliably activated for each stamp signal.
0 can be rotated once. Moreover, this one rotation is an irreversible operation since the stamping drum 10 has a unidirectional rotation means, and the presence of the stamping signal ensures that the stamp is definitely made. Furthermore, since the plurality of character wheels 14 are fixed by the locking means 20, they do not rotate unstablely during stamping. Furthermore, even if, for example, a date stamp (not shown) or the like is attached and the date stamp is rotated from the outside, the character wheel 14 is fixed by the locking means 20, so that no external operation is required. Possible.

The payment amount stamp setting mechanism 30 is provided with a numeric setting dial 34 mounted on a frame 33, which engages with each character ring 14 of the stamp drum 10 and rotates each character ring 14. A lock means is provided to prevent rotation of the number setting dial 34, and the number setting dial 34 is stamped on the frame 33.
A swinging means 40 is provided which is connected to the numeral setting dial 34 and swings so as to be rotatable from the outside of the machine. When the dials are connected to each other, the following effects can be obtained because a release means is provided for unlocking the lock means 20 of the character ring 14 and the number setting dial 34, respectively.

That is, since the numeric setting dial 34 is normally prevented from rotating by the locking means 20, the numeric running dial 34 does not rotate unstablely. Moreover, the character ring 14 of the stamping drum 10 is also locked by the locking means 20.
Since the rotation of the stamp drum 1 is prevented by
The 0 character ring 14 and the number setting dial 34 are always in a corresponding relationship, and therefore, the number that matches the number to be stamped exposed on the stamping drum 10 is positioned on the circumferential surface of the number setting dial 34 visible from the confirmation window. This allows the number to be stamped to be visually recognized via the number setting dial 34. Furthermore, when the frame body 33 is swung by the swiveling means 40, the lock between the character ring 14 and the numeric setting dial 34 can be released, and by rotating the numeric setting dial 34, the digits can be set according to this rotation. The wheel 14 can be rotated and a set amount can be set. However, even if an attempt is made to rotate the number setting dial 34 by an external operation, the locking means 20 will not be released unless the dial 14 is swung to rotate, so rotation will not be possible.

Cumulative payment amount display mechanism 70 and remaining amount display mechanism 80
Each number display wheel 75 is provided so as to be rotatable at a certain angle by a rotation means having a function of fixing and holding the display foil, and a number switch 5C for converting the displayed number into an electric signal is installed in parallel on this display wheel 75. Because of this configuration, in addition to the display function, it is possible to configure a display mechanism that can mechanically store the total amount of stamps and the remaining amount. Therefore, even in the event of an unexpected accident such as a sudden power interruption or voltage drop, data on the cumulative amount paid and the remaining amount will not be lost, making it possible to provide a highly reliable payment meter.

A rotation confirmation swinging plate 93 provided to swing by engaging with the engagement pin 91B of the stamping drum 10 at the initial stage of rotation of the stamping drum 10, and this rotation confirmation swinging plate 93
This is because a pair of stamping drum rotation confirmation mechanisms 90 are provided, each consisting of a swinging holder 94 that locks and holds the drum in a swung position by an engagement pin 91B and releases this holding in response to a lock release signal. In combination with the configuration with the unidirectional rotating means provided on the stamping drum 10, by detecting the swinging of the rotation detection plate 91, it is possible to reliably confirm that the stamp has been stamped.

Then, when the paper is located in the paper insertion slot 3 of the machine frame 2, the control mechanism 100 issues a start signal, and this start signal compares the set amount with the remaining amount, and only when the remaining amount is large, closes the clutch once. 52, the amount displayed on the cumulative payment amount display mechanism 70 and the remaining amount display mechanism 80 is updated by the signal generated by the rotation confirmation rocking plate 91 of the stamping drum rotation confirmation mechanism 90, and after each update is confirmed, the amounts are updated. Since the locking release signal is sent to the stamping drum rotation confirmation mechanism 90, the operation contents can be reliably maintained mechanically even in the event of an unexpected accident such as power failure or power interruption.

That is, the amounts displayed on the cumulative payment amount display mechanism 70 and the remaining amount display mechanism 80 are updated by the signal generated by the swinging of the rotation confirmation swing plate 91 of the stamp drum rotation confirmation mechanism 90, and after each update confirmation, Since a lock release signal is sent to each stamp drum rotation confirmation mechanism 90, even if some kind of power failure occurs during operation, the remaining balance can be confirmed by confirming the swing of this rotation confirmation swing plate 93. It is possible to detect whether or not the cumulative total has been updated. Therefore, it is possible to mechanically memorize the stamping operation state, and a highly reliable payment meter can be constructed.

As explained above, according to the present invention, the configuration can be extremely simplified compared to the conventional payment meter configured to be mechanically interlocked.
Also, while using a microcomputer,
The memory contents are not lost even in the event of a sudden power outage, and various excellent effects can be obtained.
