The specific embodiment
For above and other objects of the present invention, feature and advantage can be become apparent, a preferred embodiment cited below particularly, and cooperate appended diagram, be described in detail below:
Fig. 1 shows that a present invention is located at the circuit block diagram of ink gun 1 in the printing equipment, ink gun 1 in printing equipment has a controller 10, an ink gun casket 11, ink gun 12 and has two storage elements 13,14 in ink gun, the horizontal drive circuit 15 and first logical block 16 and second logical block 17.
Above-mentioned controller 10 is that (is example at present embodiment with an ink gun to being installed in corresponding ink gun 12 in the ink gun casket 11 in order to output control signal, also be useful on the printing equipment with a plurality of ink-jet caskets), ink gun 12 has a data wire Data, and a clock pulses line C1k and a brake line (latch line) Latch is coupled on the controller 10.Storage element 13 (first storage element) has n position buffer, can store the n bit data that is transmitted by data wire Data, has m position recognition data in this n position buffer, and all the other n-m positions then are line data (bank data); First logical block 16 for example is a m position and door, and it receives the m position recognition data that is passed by storage element 13, and produces one first signal according to this m position recognition data.This second logical block 17 for example be one with the door, its two input is that the braking signal that this first signal of reception and this brake line Latch are passed is done a comparison, and export one second signal to storage element 14, storage element 14 (second storage element) has n-m position buffer, in order to store the n-m position line data that passed by storage element 13, whether this storage element 14 exports these n-m position line data to horizontal drive circuit 15 according to this second signal decision.The n-m position line data that 15 receptions of horizontal drive circuit are passed by storage element 14 are to drive corresponding line.
During practical operation, controller 10 can cooperate clock pulses line C1k the n bit data to be imported in regular turn in the n position buffer of storage element 13, has m position recognition data in this n bit data, this m position recognition data can reach in first logical block 16 does a comparison, after comparison, can export in first signal or first signal to the second logical block 17 of second state (for example logical zero) of one first state (for example logical one), if on behalf of this recognition data, first signal that is output as first state promptly conform to, if what receive is that on behalf of recognition data, first signal of second state then do not conform to.Second logical block 17 is done second signal of comparison back output first state (for example logical one) or second signal of second state (for example logical zero) with first signal and braking signal again.Receive when this storage element 14 and be about to n-m position line data behind second signal of first state and export on the horizontal drive circuit 15 to drive corresponding line; If storage element 14 receives second signal of second state and then do not export n-m position line data to horizontal drive circuit 15, in other words ink gun promptly can't move.
Fig. 2 is to detailed circuit that should Fig. 1, in this preferred embodiment, storage element 13 has 32 buffers (n=32) in order to store 32 bit data, wherein last 8 is recognition data (m=8), first logical block 16 is one 8 and door (an and gate), its 8 inputs are coupled to corresponding the 25th (B25) to the 32nd (B32) buffer, and itself and on input, have reverser corresponding to the 26th, 30 and 31 buffer.Second logical block 17 be one with the door, it has 2 inputs and is coupled to respectively in the output of the brake line Latch and first logical block 16.Storage element 14 has 24 buffers (n-m=24) to receive 24 line data that storage element 13 is passed, by this, when action cooperated clock pulses line C1k data to be imported in regular turn in the buffer of storage element 13 by data wire Data after, in the 25-32 position of buffer because be belong to that therefore recognition data export these 8 recognition data to first logical block with door 16 in, if these 8 data that recognition data is as shown in table 1, then its input and door 16 are after understand first signal of output logic 1 after the logical operation, if if not as the data in the table 1, then by second signal of the first logical block output logic 0, represent the identification code of this ink gun and do not meet.
