Title: Magnetic tape cassette
Inventor: YAMAMOTO KOUZOU
IPC: G11B23/087
Filed: 1981-09-30
Abstract: PURPOSE:To drive a cassette for a long period of time with a VTR of small torque, by securing >=1:1 rotational ratio between a driver pair which interlocks a driving reel shaft of the VTR and a tape reel pair which interlocks said driver pair. CONSTITUTION:A case 6 has a large size corresponding to the cassette loading part of an existing cassette device and contains drivers 4 and 5 which are fitted to a driving shaft of a VTR. At the same time, a case 9 has a large size enough to wind a large quantity of tape T and contains tape reels 7 and 8 which interlock the drivers 4 and 5. A 1:2 ratio, for example, is set between the diameter X of gears 18 and 19 of the drivers 4 and 5 and the diameter Y of gears 20 and 21 of the reels 7 and 8 respectively. Thus the torque of an existing driving reel shaft is increased to the torque of a cassette having a reel of a large diameter. As a result, a tape is smoothly taken up and rewound with no delay within the cassette.

Abstract: PURPOSE:To keep the speed of discharge of an ink drop constant even when the quantity of the ink drop injected is varied and a gradation is expressed by altering first voltage so that the difference of first voltage lowering pressure generated from an element and second voltage is kept fixed when the gradation is expressed. CONSTITUTION:Second voltage Vop is set in order to obtain a gradation corresponding to recording data while first voltage Vrev is set so as to be made lower than Vop by constant voltage at all times, and a drive signal is applied to a recording head 2 from a head driver 24. The gradation is expressed so as to be respectively shown in (A) when the quantity of ink drops injected is reduced, in (B) when the quantity is brought to an intermediate extent and in (C) when the quantity is increased. The difference of Vrev and Vop is equalized even regarding Vop corresponding to any gradation. Consequently, the gradation can be represented in quite the same manner as conventional devices though the speed of discharge is made fixed even regarding any Vop. Minimum Vop need not be determined in the expression of the gradation so that the speed of discharge is not made smaller than a certain constant value, the value of minimun Vop can further be reduced, and the gradation having extremely low reflection density can be expressed.
