摘要： PURPOSE:To make it possible to prevent the lowering of printing quality caused by abrasion, by a method wherein the number of printing times of frequently- used types high in frequency to be used are counted and, when they reach the predetermined number of times, said types are exchanged with the same new types. CONSTITUTION:A plurality of type tray 1 each having frequency used types 8 high in frequency to be used are received in a cylindrical type case. A control part 11 reads type data from a printing data feed part 12 to collate types with a type list and, when they are the frequently-used types, the total number of printing times thereof are counted by a memory counter part 15 to be compared with the set number of times due to a setting apparatus 13 and, when the counted number of printing times are equal to or less than the set number of times, a printing part 14 is operated to perform printing. When reaching the set number of times, the counter part is cleared while the address data of the frequently- used types 8 is altered to that of the same new types and the printing part 14 is driven on the basis of this address data. By this method, printing quality and the use efficiency of the type plate can be enhanced.
摘要翻译：目的：为了能够防止由磨损引起的打印质量的降低，通过对使用频率高的频繁使用的类型的打印次数进行计数的方法进行计数，并且当达到预定次数时，所述类型与相同的新类型交换。构成：在圆筒型的情况下，接收使用频率高的8种频率使用的多个型式的托盘1。控制部分11从打印数据馈送部分12读取类型数据以与类型列表进行比较，并且当它们是经常使用的类型时，其总打印次数由存储器计数器部分15进行计数以进行比较具有由于设定装置13而设定的次数，并且当打印次数等于或小于设定次数时，打印部14被操作以进行打印。当达到设定次数时，计数器部分被清除，而频繁使用的类型8的地址数据被改变为相同新类型的地址数据，并且基于该地址数据驱动打印部件14。通过该方法，能够提高印版的印刷质量和印版的使用效率。

摘要： PURPOSE:To obtain the printer in the title wherein circuit constants in a constant current mirror circuit are changed in correspondence with the kinds of the types to be printed and printing conditions, a hammer solenoid current is controlled, and fine adjustment of the printing pressure can be performed. CONSTITUTION:Bases of transistors 4-7 are connected to a constant voltage power source Vcc through resistors 15-18 and the output terminals P1-P4 of a printing pulse circuit 19. A memory circuits 30 stores printing pressure data, and makes the output terminals P1-P4 of the printing pulse circuit 19 output a negative printing pulse Pm in response to the types to be printed. The printing pressue can be controlled by the magnitude of the solenoid current iL. The resistance values of the resistors 11-14 are changed. Transistors 4-7 for controlling the constants of the mirror circuit which is turned ON in correspondence with the kinds of the types to be printed are changed. The overall adjustment of the printing pressure is performed by changing the resistance value R9 of a resistor 9 by a switch 29.

摘要： PURPOSE:To augment the capacity of types with an increase the number of comb-shaped type plates capable of being housed in a type case drum by housing them radially on the circumference of the drum to facilitate the mechanism of selecting strip-shaped type plates. CONSTITUTION:As a type case rotation motor 13 is driven with a driver, a type case drum 11 is rotated to select a desired comb-shaped type plate 10 while a type case slide motor 14 runs with the driver. A type case drum 13 slides horizontally and a desired type on the comb-shaped type plate 10 stops at a position on a hammer 16. Then, a type plate shifting motor 17 is driven with the driver to pull up the comb-shaped type plate 10 by way of a type plate shifting shaft 19 and a type plate shifting belt 18 whereby upper types 30a- or lower type 31a- are selected.

摘要： PURPOSE:To improve the printing speed with a greater selection speed leassening the selection distance by dispersing types of a highly frequent use prepared in plurality over a plurality of type plates. CONSTITUTION:Interface signals 30 are converted into parallel data with a serial port 31 and temporarily stored in a buffer 32. A control section 33 picks up the address of a type case drum 2 and the address of types on a type plate 1 from a data memory 34 according to a chinese character stored in the buffer 32 to instruct a drive section. For example, a type plate 41-1 in which characters of a highly frequent use are set in package is mounted in type case drum addresses 40-1, 40-8, 40-17 and 40-26. Types are selected from a type plate mounted in a type case drum address the closest to the current one and a printing is performed.

摘要： PURPOSE:To prevent contact between the rear end of a material and a lower tool post when the material passes through the captioned machine. CONSTITUTION:A lower tool post 8 is arranged so as to be placed in an F1-P1 position rotated by theta deg. within 0 deg.-60 deg., namely in a position of angular displacement to the main roller 9 side, that is, when a stop and standby position of the main crankshaft 1 at the time of passage of the material 10 through the machine is moved to the exit side roller 9 by theta deg., it turns to P1 posiion due to the influence of an oscillating link (unillustrated). Accordingly, the lower tool post 8 is prevented from being brought in contact with the rear edge of the material 10. The lower tool post is moved to the exit side roller 9 due to rotation of the main crankshaft 1, and an interval between the exit side roller 9 and the lower tool post is shortened, then the rear end of the material 10 does not make any contact with the lower tool post.

摘要： PURPOSE:To obtain a type printer facilitating the control of the quality of types by counting the number of printing of a type of the highest frequency in use in a type board composed of a plurality of types and by making an alarm device operate when a counted value becomes a prescribed value. CONSTITUTION:A control device 12 generates a control signal based on printing data sent from a printing data delivering part 14, selecting types and operating a printing means 18. Then, the means 18 selects a type in the printing data from a type tray 2 consisting of (m) sheets of type boards 1 and conducts printing. Receiving the printing data, the control device 12, which memorizes the printing data of one selected type of high frequency in use, checks whether the type of the received printing data is the selected one or not, and when it is the selected, the device delivers a signal to a counting device 22, which counts the signal. The total number of printing is delivered to the control device 12, and when the number reaches a prescribed number, a signal is delivered to an alarm device 20 and an alarm is delivered therefrom.

摘要： PURPOSE:To reduce the storage amount of a hammering force code by arranging types of the same number of picture elements or adjacent types in one type board of a printer having many type boards and typing the type board with common typing force. CONSTITUTION:In a printer in which many type boards 3 having a plurality of types 22, 23 are rotatably arranged in a type housing drum 1, and desired type board 3 is selected from the drum 1, thereby typing the type by a hammer on a platen 15 for printing, types of the same number of picture elements or adjacent types 22, 23 are arranged in each type board 3, and are typed with typing force determined for each type board 3. That is, the hammering force of the hammer is controlled by checking the address of the type housing drum 1 containing the type.

摘要： PURPOSE:To obtain extensive printing pressure levels and to decrease the load of an upper level controller, by digitally processing the printing pressure, and performing the printing pressure control and ribbon feeding control by the same microcomputer. CONSTITUTION:When a power source is turned ON, the microcomputer 9 is initialized. At first, a blank feeding of the ribbon is performed to obtain the proper printing density. When a striking command is sent from the upper level controller 6, the command is received through an input circuit 8, and a code A corresponding to the striking command data is read out of a memory circuit 15. A variable code from a printing pressure switch 7 is received, and a code B corresponding to the variable code is read out of the memory circuit 15. Both codes A and B are applied to a striking solenoid 12 through a D/A converter 10 and a driver 11 as a voltage in analog quantity. After the printing, a ribbon feeding motor 14 is driven through a motor driver 13.
