Abstract: An information-arranging device, wherein a plurality of records information units are initially stored at random in first and second memories in a state separated by record-positioning codes. The records are read out one after another from the forward end of said first and second memories. The key words of every two records read out from said first and second memories are compared in respect of numerical largeness or value by a comparing circuit to determine the sequential order of said key words. The records, whose key words have thus been compared in numerical value are arranged in a decreasing or increasing sequential order to form a block with the intervening one of the information codes converted into a different code. Said sequentially arranged records are stored in a third memory in the form of a block.

Abstract: An electric control device for printing apparatus in which electric signals, representing letters and the positions of words formed by the letters, are transmitted from a keyboard to storage means in which the signals are stored in their sequence of generation. The storage means includes two one-character, seven-bit dynamic shift registers, coupled in series, through which the signals are shifted. A typewriter printing mechanism is coupled to the storage means, and it prints the stored text word by word, each formed by the letters represented by the signals stored in the storage means. A control unit coupled to the printing means, keyboard and storage means controls the input of the signals to the storage means, and the read-out and printing of the signals by the printing means, so that the signals are transmitted into and out of the storage means and printed word by word in the sequence in which they were generated.

Abstract: An ink jet character recording apparatus comprises a first deflection electrode for deflecting the stream of ink droplets ejected from a nozzle in a direction perpendicular to the direction of relative movement between a recording paper and the nozzle, a second deflection electrode for deflecting the stream of ink droplets in a direction substantially perpendicular to the direction of deflection effected by the first electrode, and an ink collector for collecting the ink droplets.

Abstract: A printing device employs a printing drum on the peripheral wall of which a plurality of character types are arranged in the axial direction and in the circumferential direction. The axial movement and rotation of the drum are independently controlled by comparing the position of a new character type on the drum to be printed with that of the immediately preceding one of already printed character types thereon at each printing step in response to electric printing information. A hammer is disposed close to the outer periphery of the drum. The hammer advances step by step in printing in the axial direction of the drum independently of the drum to determine the printing position with respect to a record sheet and selectively strikes the opposed surface of the drum through the record sheet. The printing device can thus attain a mechanical driving system for the drum and hammer which has the simplest construction, the least probability of trouble, and a highest possible printing speed with ease.
