There is provided a recording and/or reproducing apparatus which may include a cassette insertion slot formed at a front panel, an opening/closing lid for opening/closing the cassette insertion slot, a cassette compartment, and cassette double insertion blocking means. The cassette compartment may include a cassette loading holder for loading and unloading a cassette inserted through the cassette insertion slot while pushing the opening/closing lid open inward by moving between a cassette loading position and a cassette ejecting position along a substantially L-shaped path extending horizontally and vertically. The cassette double insertion blocking means may be disposed in the cassette compartment and moved to a cassette double insertion blocking position inward of the cassette insertion slot in synchronization with an operation of loading the cassette by the cassette loading holder, thereby blocking insertion of additional cassette after one cassette is already inserted without blocking an opening/closing operation of the opening/closing lid.
摘要:
In an adjusting method for a cathode position of an electron gun, an apex point of a dome-shaped cathode is detected and then a positional adjustment is executed by moving a first grid in a X-Y direction so that a center of a grid aperture is coincided with the position of the apex point, at first. Next, a sleeve ring and a collar portion of a sleeve holder are welded together by a laser beam. The a dgk-vale adjustment is done so as for a gap between first grid and apex point of the cathode to be a predetermined value and welded by irradiating the laser beam to a superposed position of the cathode structure and the sleeve. According to the present invention, these positioning adjustment and the dgk-value adjustment are able to be executed independently.
