The specific embodiment
With reference now to accompanying drawing, describes band supporting arrangement and the structuring China ink tape cell that is used for image printing apparatus in detail according to the preferred embodiment of the present invention.Fig. 1 is the sectional view of band supporting arrangement and structurized black tape cell, and Fig. 2 is the amplification sectional view of an expression band supporting arrangement part.
Structurized black tape cell comprises the belt carcass 4 of hollow and is with 1 around the rolling China ink that belt carcass 4 is wound into cylindrical form.In the inboard of belt carcass 4, leave an end specified distance of belt carcass 4 separator disc 6 is installed.In separator disc 6, form narrow opening or the stria 9 that substantial radial is arranged.In the outside of separator disc 6, be provided with in the cylindrical hole be installed in belt carcass 4 and support the belt carcass reel element 11 of belt carcass 4, belt carcass reel element 11 in conjunction with reflective photoelectric sensor 10 so that detect the rotation of separator disc 6.The other end at the belt carcass 4 relative with belt carcass reel element 11 is provided with dismountable belt carcass reel element 8, as shown in Figure 1.
With reference to figure 2, the overall diameter of belt carcass reel element 11 is made with the interior diameter of belt carcass 4 roughly the same, and the sensor 10 that is combined in the belt carcass reel element 11 is positioned on the point of the geometric center that departs from separator disc 6 slightly.Because between the separator disc 6 on the inboard of the end of belt carcass 4 and belt carcass reel element 11, being provided with this sensor 10, sensor 10 do not cause the overall dimension of band supporting arrangement to increase.Because substantial radial stria 9 is formed in the separator disc 6 along its rotation direction, during all strias 9 when sensor 10 is formed on separator disc 6 after testing in, each rotation of detection belt carcass 4.In order only to detect the single rotation of belt carcass 4, the quantity that is formed on the stria 9 in the separator disc 6 does not need big like this.In order to detect the specific quantity that belt carcass 4 rotates, the quantity that is formed on the stria 9 in the separator disc 6 is preferably made big as far as possible so that realize high accuracy.
Fig. 3 represents the shape of the separator disc with stria 96 seen from the one side.When using the band supporting arrangement of this embodiment, it is black with in the cylindrical hole in 1 the supply side belt carcass 4 that the user at first inserts belt carcass reel element 8 therefrom supply.Then, the user will be loaded with the rolling China ink and be installed on the belt carcass reel element 11 that is combined with the sensor 10 that is fixed on the equipment body with 1 belt carcass 4.During printing operation, be with 1 o'clock consuming China ink, China ink with 1 band organization of supply 12 by comprising band supply stepper motor from supply side belt carcass 4 with the specific speed supply.At this moment, the stria 9 that is formed on by detection in the separator disc 6 in the belt carcass 4 that is installed in rotation of sensor 10 determines whether belt carcass 4 rotates.If the output of sensor 10 is switched under open and closed, the black tape cell of current use is correct standardized product.If the output of sensor 10 can not be switched between open and closed, the black tape cell of current use is wrong or off-gauge product, perhaps incorrect the installation.Under one situation of back, the band supporting arrangement produces can be heard or appreciable warning, so that remind the user abnormal conditions to occur.When the number count of 10 pairs of strias 9 of sensor, the band supporting arrangement determine the quantity of stria 9 whether reach with belt carcass 4 or rolling China ink with the corresponding value of 1 rotation.
According to the present invention, separator disc 6 can have a plurality of protuberances, rather than stria 9.Equally, the band supporting arrangement can adopt transmission sensors or switch, rather than described reflective photoelectric sensor 10.
Adopt the described configuration of band supporting arrangement, by for China ink with 1 each rotate in the band supply stepper motor amount of supplying count, can calculate the China ink band and once rotate the China ink supplied with 1 length L.
Therefore,
L=(substep quantity (supply)) * (amount that the motor per minute step is supplied) (1)
Here, China ink provides by following equation with 1 overall diameter D:
D＝L/∏ (2)
If known China ink is with 1 overall diameter D, can calculate the quantity of China ink from the well known equation that is used to calculate the rolling product length with not use part (remainder) LL of 1.Calculating China ink represents with for referencial use below with the equation commonly used of the length L L of 1 remainder:
LL＝(∏(D
2-d
2)/4)/t (3)
Wherein D is a China ink with 1 overall diameter, and d is the overall diameter of belt carcass 4, and t is a China ink with 1 thickness.
The band supporting arrangement is determined the length L L of China ink with 1 remainder in this way.When China ink becomes when being equal to or less than specified quantitative with the length L L of 1 remainder, the band supporting arrangement is indicated and is notified the user by producing buzzer or vision.In this embodiment, China ink with the length L L of 1 remainder can according to China ink with 1 each rotate in the band stepper motor quantity of supplying come clearly to determine.Even being structurized black tape cell, the favourable part of the described configuration of this embodiment from equipment body dismounting and install once more, also can determine the length L L of China ink with 1 remainder.
The band supporting arrangement prints image applicable to known image printing apparatus so that use China ink to be with on paper.Also the CPU that is permitted to calculate the image printing apparatus of device as the band remainder calculates the quantity of not using partial L L.Whether CPU detects the China ink band by the rotation that detects opening or protuberance and correctly installs.Image printing apparatus has the indicator that is used to indicate the quantity of being calculated by CPU of not using partial L L, makes thus the user confirms when to change the China ink band.When the China ink band was not correctly installed, indicator provided warning.
As described alternative based on Calculation Method, the China ink that can obtain according to test with 1 use part or use the quantity of part and the quantity of the supply substep of band supply stepper motor between relation determine that China ink is with 1 use part or use quantity partly.According to this alternative method, the China ink that test obtains with 1 use part or use the quantity of part and the quantity of the supply substep of band supply stepper motor between the pass for example tie up to and represent among Fig. 6.The chart that therefore use obtains determines that according to the supply substep accumulated quantity of stepper motor China ink partly or uses quantity partly with 1 use.In the example of Fig. 6, trunnion axis is represented the accumulated quantity of the supply substep of stepper motor, and vertical axis represent black length with 1 remainder.
For example when China ink has reached 10 meters with the length of 1 remainder, if hope indication China ink is with 1 the quantity of not using part, when the accumulated quantity of the supply of stepper motor substep reached with chart on China ink when being 10 meters the corresponding value of point with the length of 1 remainder, provide this indication.The band supporting arrangement of described embodiment is applicable to the equipment that is used to support rolling China ink band or rolling printing paper of any kind.When being used for this equipment, the band supporting arrangement can high accuracy detects the quantity of not using part of China ink band or printing paper.A kind of duplicator for example adopts the stepper motor with the speed supply China ink band of 1/7.7 millimeter-1/15.4 millimeter of each substep of stepper motor.Compare with the length of printable area on the every printing paper, because this China ink band supply length in each substep of stepper motor is enough little, the band supporting arrangement that is used for duplicator can detect the quantity of not using part of China ink band exactly.
