Title: Thermal head and thermal printer
Inventor: NAKANISHI KANJI
IPC: B41J2/335
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To nearly eliminate a positional shift of a separation point even when a tension change is brought about to a recording material, by forming a steep part having a larger curvature than a contact area between a heat-generating element array and the recording material, at the separation point where the recording material starts to be separated from the heat-generating element array. SOLUTION: A heat-generating element 21 is shifted with respect to a partial glaze 13 of a projection to the upstream side in a recording material feed direction. A heat-generating element array 20 is thus constituted. A platen roller 26 is arranged with a rotational center RC thereof shifted to the upstream side of the feed direction with respect to a top point of the partial glaze 13. At a contact area CR of the heat-generating element array 20 to a recording material 2, a contact area LCR at the downstream side in the feed direction which continues from a contact area MCR of a part of the heat-generating element 21 to the recording material 2 is set longer in comparison with a conventional heat-generating element array.  A steep part 38 having a larger curvature than the LCR is formed at a position of a separation point PP where the recording material 2 starts to be separated from the heat-generating element array 20. Even when a tension change is brought about to the recording material 2, the recording material 2 is let away from the heat-generating element array 20 because of the steep part 38, and the separation point PP is hardly shifted. A density change resulting from the shift of the separation point is accordingly suppressed.

Abstract: PURPOSE:To improve the accuracy of a tracking servo and a focus servo by adopting the constitution that two sets of holders holding the optical system and of support shafts and bearings turnably and slidably to each other are provided in parallel in the optical axis direction of the optical system. CONSTITUTION:The tracking control is applied by using an electromagnetic force between a current flowing to a coil 16 in Y direction and a permanent magnet 15 to slide an objective lens holder 2 in the X direction of the shafts 5, 6 via the bearings 3, 4. Since the friction between the bearings 3, 4 and the shafts 5, 6 is less in this case, support means 11-14 are not almost vibrated. Further, the focus control is applied by an electromagnetic force between the current flowing to the coil 18 and the magnetic field generated by a permanent magnet 17 to move the objective lens holder 2 in the Y direction. Then the support means 11-14 consist respectively of a damping member 11b and an elastic member 11a to reduce the vibration attenuation time of the optical support 2 in the optical axis direction, the generation of sub resonance of the optical system support is prevented to improve the accuracy of the tracking servo and focus servo.

Title: Disk cassette
Inventor: AOKI SUNAO
IPC: G11B11/105
Filed: 1994-01-26
Abstract: PURPOSE:To increase memory capacity by providing a clearance groove between a groove to draw in and an inserted front end surface to set the size of a disk cassette large. CONSTITUTION:When a disk cassette DK is inserted into a cassette holder 26, an inserted front end surface 1c pushes a shutter opening pin 5 and a pin 31 is moved along a can hole 30 to open the shutter 5. When it is inserted, the inserted front end surface pushes a release lever part and a lock claw plate 44 is rotated. The cassette drawing pin 37 in the waiting position is located in the position projecting from the side within the cassette holder 26, but since the cassette DK has a clearance groove formed in that position, the cassette DK can be inserted without abutting on the pin 37, and the pin 37 reaches the drawing groove 8. Therefore, the waiting position of the pin 37 can be allowed to come near to the insertion area of the cassette DK, so that the size of the cassette DK may be set larger to that extent.
