  • Patent number: 7619851
    Abstract: A cartridge holder is disclosed that includes a cartridge supporting member that supports an inserted cartridge corresponding to a first cartridge or a thicker second cartridge; a cartridge upper face holding member that is normally positioned at a first height position for holding down the first cartridge; a cartridge upper face holding member supporting mechanism configured to move the cartridge upper face holding member with respect to the cartridge supporting member; and a lock mechanism configured to lock the cartridge upper face holding member in the first height position. The cartridge supporting member and the cartridge upper face holding member define a cartridge accommodating space. The lock mechanism remains locked when the first cartridge is inserted, and unlocks when the second cartridge is inserted. When the second cartridge is inserted, the cartridge upper face holding member is raised, and the size of the cartridge accommodating space is changed.

  • Patent number: 7522374
    Abstract: A tape cassette recording/reproducing apparatus in which a long length ejection for ejecting a tape cassette by a longer distance than usual is stably executed is disclosed. The tape cassette recording/reproducing apparatus includes a tape cassette housing moving mechanism that moves a tape cassette housing to an ejecting position by rotating a rotating arm, and a tape cassette pushing out mechanism that pushes out a tape cassette by a predetermined distance from the tape cassette housing positioned at the ejecting position. The tape cassette pushing out mechanism is moved by an excessive rotation of the rotating arm.

  • Patent number: 7408736
    Abstract: A magnetic recording/reproducing apparatus is disclosed that is arranged to receive a tape cassette accommodating a tape recording medium that is selectively loaded thereto. The loaded tape cassette is selected from plural types of tape cassettes accommodating tape recording media with differing widths. The magnetic recording/reproducing apparatus includes a rotating drum unit with a rotating head, and a loading mechanism that pulls the tape recording medium of the loaded tape cassette out of the loaded tape cassette, winds the tape recording medium of the loaded tape cassette around the rotating drum unit over a winding angle, and forms a tape path. The loading mechanism adjusts the winding angle for winding the tape recording medium of the loaded tape cassette according to the width of the tape recording medium of the loaded tape cassette.
