Title: Loading device of cassette
Inventor: TAKAGI NOBUAKI
IPC: G11B15/675
Filed: 1983-08-30
Abstract: PURPOSE:To stabilize the loading operation of a cassette by rotating a cassette holder hold by a rotary base plate around a rotational fulcrum different from that of the rotary base plate at the rotation of the rotary base plate and then descending the cassette holder vertically. CONSTITUTION:When the cassette 31 is inserted and the rotary base plate 23 is rotated, the cassette holder 22 is rotated in the counterclockwise because a guide pin 22b is abutted to the sliding surface of a sliding guide plate 35. Although the guide pin 22c is slightly descended, the leading end of the cassette 31 is higher than a capstan 37 even at a position where the cassette 31 is set up horizontally. When the rotary base plate 23 is rotated moreover, the guide pins 22c, 22b are descended along a guide groove 27a, and the sliding guide plate 35 respectively. Then, a guide pin 22d on the back end of the cassette holder 22 is engaged with a guide groove 30 a of a cassette guide 30 and the casstte holder 22 is smoothly descended in the vertical direction. Thus, the cassette is prevented from abnormal operation at the loading time of the cassette and the operation is stabilized.

Title: Ink jet recording head
Inventor: MASUDA KAZUAKI
IPC: B41J2/14
Filed: 1984-07-31
Abstract: PURPOSE:To conduct excellent printing even immediately after a shaking such as a vibration and a shock by forming an obstacle in an ink flow path. CONSTITUTION:In an ink jet recording head with an ink storage tank 3, an ink flow path 4 communicated with an orifice 1 from the ink storage tank 3 and a discharge energy generating body, an obstacle is shaped in the ink flow path 4. The obstacle is formed to a shape, such as a projection, irregularities, a wall, etc. When such an obstacle is formed in the ink flow path, the contact area of ink is increased, holding force between ink path shaping members for ink can be augmented by interfacial tension between both members, and the flow-path resistance of the whole ink flow path can be magnified because the length of the ink flow path is lengthened, thus preventing the movement of ink in the ink flow path on the vibration of the head, then obviating peripheral contamination due to the impossibility of printing and the leakage of ink.
