摘要： PURPOSE:To prevent the deviation of printing dot position, unevenness of printing concentration, and blankness of printing by normally operating a printing hammer by a method in which voltage to be applied to a coil is controlled in such a way as to interrupt the increase in suction force resulting from excessive magnetic flux. CONSTITUTION:The number of magnetically driven parts 6 is detected as the reference voltage E proportional to it and then converted into reference voltage F by a function circuit 14, and drive voltage G to be applied to a coil 11 is varied in proportion to the reference voltage F. The function circuit 14 is so designed that the reference voltage F becomes an increasing function of the reference voltage E. Thus, as the number of the magnetically driven parts 6 increases, the drive voltage G is increased and the demagnetization amount Q is reduced. The increasing function is so set that the demagnetization amount Q is always kept at a proper value, and therefore, even when the number of the magnetically driven parts 6 is varied by printing patterns, suction force to be applied to the printing hammer 4 is not changed and printing failure does not occur because the demagnetization amount Q is always kept at a proper value.

摘要： PURPOSE:To perform excellent printing even though a printing pattern is changed by controlling a voltage applied to a coil by a controlling means which outputs a control driving signal. CONSTITUTION:A printing data B is inputted into a maximum value circuits 11 in synchronization with clock signals T. The number of the clock signals during the period the printing data B becomes continuously high from the rise of a starting signal A to the rise of a striking signal. A maximum value M is judged and stored in the circuit 11. A function circuit 12 determines a voltage control signal F corresponding to the maximum value 7 based on the function defined in the inside. A voltage control circuit 13 converts a power source voltage E to a driving voltage K which is proportional to a voltage control signal F. A pulse generating circuit 14 generates a pulse W having a specified pulse width in synchronization with the rise of the striking signal. A driving circuit 15 applies the driving voltage K to the coil 4, whose driving is specified, for the period of the pulse width of the pulse W in synchronization with clock signal T and drives a printing hammer 6.

摘要： PURPOSE:To reduce the capacity of an ROM by writing the dot matrix information to a part corresponding to a character code to be changed or added. CONSTITUTION:A code showing a changed instruction of the dot matrix information is transferred from a superior device 1, and then a code designating a character code is transferred. A microprocessor MP4 said code and designates the head of the address where the dot matrix information is stored for the code of a character generator CG7. Then the dot matrix information of a character is transferred successively from the device 1 for each byte, and therefore the MP4 writes each information to the CG7 for each reception of byte. Then, +1 is added to the address of the CG7. When the transfer is through with all bytes, the change ends with the dot matrix information. Hereafter the print is possible for the changed character. In the same way, it is possible to add the dot matrix information to the CG7.

摘要： PURPOSE:To accurately adjust the driving time of a typing hammer in a printing machine having a typing hammer by detecting the position of a hammer block and generating a hammer drive signal after the prescribed delay time from the detection signal. CONSTITUTION:An encoder disc 5 for identifying the position of a reciprocating hammer block is provided with a slit 10 corresponding to a dotted position to be typed during the one stroke operation of the hammer. Slid 10 signals f from a detector 10 for indicating the presence or absence of the slit 10 are sequentially stored in the addresses of a memory address 3 counted by a clock CLK1 signal a. The signal f loaded in a memory 106 is outputted as a slit delay signal h from a flip-flop 107 when the address e is returned to 0 address by a clear signal d from a counter period circuit 105 and becomes the address at the loaded time, thereby setting a driving time of the hammer 1. The delay time of the signal h can be arbitrarily set by adjusting the period of the counter.

摘要： PURPOSE:To simplify the constitution of a printer, by providing the means changing the voltage fed to the coil end of a print hammer, changing the current value flowing to the hammer coil corresponding to the applied voltage and reducing the noise when the hammer collides with the buffer material. CONSTITUTION:A print hammer coil 1 is connected between the power supply E and ground via transistors TR2, 3 and a current detection resistance 4, and the voltage between the emitter and the collector of TR2 is changed by adjusting a variable resistance 5 so that the applied voltage of the coil 1 can be changed. Further, the collector of a control TR6 which is normally conductive and turned off for a given time when a print instruction is input from the hammer controller, and the output of an operational amplifier comparing the output of a variable resistance 8 and the resistance 4, are connected to the base of TR3. Further, the current value flowing to the coil 1 is changed in response to the applied voltage to reduce the noise when the hammer collides with the buffer material, and the support mechanism of the buffer member can be made unnecessary to simplify the constitution of the printer.

摘要： PURPOSE:To make possible smaller size of the equipment preventing the deviation in the printing position by prohibiting the drive of the printing magnet prone to being affected by leakage flux of the adjacent printing magnet until the effect is reduced to a negligible level. CONSTITUTION:When the position of the printing hammer corresponding to the adjacent printing magnet is set at N-2 figure, N figure and N+2 figure, the magnetic interference reaches its maximum, where the printing magnet corresponding to the N figure is excited to drive the printing hammer while the printing magnets corresponding to the N-2 figure and the N+2 figure are both excited. Therefore, the drive of the printing magnet corresponding to the N bigure is prohibited during the period. To achieve this, a flag pit is added to the fubber memory where the letter code for each figure is memorized to indicate whether the printing magnets corresponding to respective figures are excited or not. The contents of the flag pits corresponding to the N-2 figure and N+2 figure is checked before the driving of the printing magnet. If both the magnets are being excited, the driving of the printing magnet corresponding to the N fugure is prohibited.

摘要： PURPOSE:To prevent a type position detecting lag caused by locating a particular mark, by placing type marks so that the type marks be displaced in the direction to part from the particular mark, where the particular mark is positioned between the type marks corresponding to types on a type transport means. CONSTITUTION:Many types 2 and mark types 3 corresponding to the types 2, respectively, are provided on a type transport means 1. In the meantime, where particular marks, for example, a start mark representing the head of a type group, or a belt mark showing a type of a type belt, are provided between the type marks 3, the type marks in front and in rear of the particular mark 4 can be positioned such that the type marks are shifted in the direction to part them from the particular 4. For example, the type mark 3 positioned forward in a moving direction of the particular mark 4 is shifted more forward in the moving direction by a distance DELTAl than a normal position. As a result, the interference between the type mark and particular makr is reduced. A shifting distance shall be determined on the basis of factors, such as a moving speed of the type belt 1, a pitch between the types, a distance between the type mark 3 and the particular mark 4 and the like.
