Title: Driving device for electro-strictive body
Inventor: SOGAMI ATSUSHI
IPC: H02N2/00
Filed: 1983-11-09
Abstract: PURPOSE:To simplify the circuit constitution by a method wherein multiple driving bodies made of a material with electro-strictive effect are simultaneously displaced in one direction while they are selectively displaced in the other directions. CONSTITUTION:Within an electro-strictive body drivers 25-27 made of a material with distortion effect, a transistor 34 to displace the driving bodies 25-27 simultaneously in one direction is provided while the other transistors 22-24 to displace them in the other directions are also provided. For example, when letters are printed by a driving body 25 only, a signal to turn the transistor 34 On is output firstly from a driving signal transmitting circuit 21. Through these procedures, all the driving bodies 25-27 may be bent and displaced simultaneously in the direction C. Next when the transistor 34 is turned OFF from the circuit 21 to output a signal turning only the transistor 22 ON, the driving body 25 only is displaced in the direction D to print letters while the other driving bodies 26, 27 are reset to the neutral position.

Title: Slide type cutter device for printer
Inventor: IMAI SABURO
IPC: B26D1/08
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To make compact and thin a slide type cutter device for a printer. SOLUTION: The slide type cutter device for printer is provide with a slit 1, a fixed blade 2 and a movable blade 3 so as to cut a recording paper printed by the printer in a breadthwise direction of the paper. The slit 1 extends along the bradthwise direction of the paper to pass the recording paper. The fixed balde 2 is set at the side of a left end of the slit, and the movable blade 3 is arranged at the side of a right end of the slit and slides forward and rearward to the fixed blade 2. When the movable blade 3 comes to an advance position, the blade 3 overlaps with the fixed blade 2, thereby cutting the recording paper. On the other hand, when the movable blade 3 is at a retreat position, the blade is separated from the fixed blade 2 and allows the recording paper to pass freely. A slider 4 supporting the movable blade 3 is engaged with an ultrasonic motor 5.  The ultrasonic motor 5 reciprocates the movable blade 3 via the slider 4 between the advance position and the retreat position.
