Title: Motor speed control circuit
Inventor: OKAGAKI HIROYUKI
IPC: H02P29/00
Filed: 1989-09-14
Abstract: PURPOSE:To improve rotation stability of a motor by varying a duty ratio to 1:1 based on a signal divided in frequency from a FG signal and the FG signal, and obtaining a gate signal. CONSTITUTION:A gate signal is formed of a FG signal and a speed switching signal D. The signal D is set to H in a three times speed rotation control mode. The output of a DFF 2 is set to H. A DFF 1 is operated at 1/2 frequency divid ing period, and a signal B becomes a 1/2 signal synchronized at the falling edge of a signal A. A gate signal of three times speed mode is formed from the signals A, B by NANDs 1-2. The signal synchronization of the gate signal of the three times speed mode is 1/2 frequency dividing waveform of the FG signal A, but its signal width of the gate becomes three times. Thus, a control cycle of a motor can be shortened to improve rotation stability of the motor.

Title: Ink film cassette
Inventor: FUJINAWA NOBUHIRO
IPC: B41J32/00
Filed: 1992-09-08
Abstract: PURPOSE:To eliminate difficult works in roll repacking time by installing elastic tongues which hold a roll itself or a member rotating together with the roll to produce a frictional load against the rotational force of the roll. CONSTITUTION:A bearing unit 51 of a lower case 50 is equipped with a pair of parallel tongues 51b which extend upward from a level 51a at an interval slightly narrower than the outer diameter of a coupling member 2a. The elastic tongues 51b, when pressed by the coupling member 2a of a roll 1a from above, is deformed elastically to produce a frictional resistance against the coupling member 2a by its restoring force. The relation is similar to the bearing unit of the coupling member 2b of a roll 1b on which an ink film 3 is wound. As a result, the frictional function is materialized only by placing the rolls 1a, 1b equipped with the coupling members 2a, 2b on the lower case 50, thereby simplifying the work for repacking an ink film cassette.

Abstract: PURPOSE:To eliminate the inconvenience of replacing only a transfer head, by a construction wherein the transfer head is incorporated in a casing at such a position that an ink ribbon is exposed, and a terminal for inputting an image signal to the head is provided at an outer wall part of the casing. CONSTITUTION:When an ink ribbon cassette 5 is fitted onto a cassette holder 7 by pushing it in the direction of an arrow A, a reel base 10 and a pin 11 engage a take-up reel and a payout reel, respectively, and an image signal supply terminal 12 and an image signal input terminal 13 are electrically connected to each other by making contact with each other. By this, an image signal is externally supplied to a head 4 through the terminals 12, 13, resulting in that a signal supply path is established. With the ink ribbon cassette 5 fitted to the cassette holder 7, transfer of images is conducted while the cassette holder 7 is moved together with the ink ribbon cassette 5, in the same manner as in a conventional image transfer device. Therefore, the head is also replaced simultaneously with the replacement of the ink ribbon.
