摘要： A tape supplying and taking up apparatus is capable of use with either large or small size tape cassettes containing reels which can be of different diameters and rotated with a high degree of accuracy by reel spindles of simple structure. Each tape cassette for use with the apparatus has a shutter of the slide type for closing access holes in the bottom wall of the cassette casing.Each of the reel spindles has a large size cassette receiving portion for receiving a tape reel of a large size tape cassette coaxial with a small size cassette receiving portion for receiving a tape reel of a small size tape cassette. The small size cassette receiving portion is smaller in diameter and disposed at a higher position than the large size cassette receiving portion. The diameter of a lower end of a reel spindle engaging hole provided in each reel hub of the small tape cassette is smaller than the outer diameter of the small size cassette receiving portion of the reel spindle. The reel spindle engaging hole of the large size tape cassette has, at a lower end portion thereof, an escape portion which is greater in diameter than the outer diameter of the small size cassette receiving portion of the reel spindle but smaller than the outer diameter of the large size cassette receiving portion and such escape portion is higher than the height of the small size tape receiving portion.

摘要： A data path control device with a first interface section for connecting to a LAN, second interface section for connecting to an external network through a small transmission capacity two-way line such as a telephone line, and third interface section for receiving a large capacity data from a large transmission capacity one-way line such as a satellite broadcast line. The data path control device changes the sender address of the data transmitted from a computer to a network based on a previously set correspondent relationship, thereby controls the path so that the large capacity data from the network is transmitted through the large transmission capacity one-way line. A path of the reply data from a network responsive to the request data from a computer outputted to an external network is selected by the computer side, and in the case that the reply data is composed of large capacity data, a satellite line having a large transmission capacity can be selected.

摘要： A tape-loading mechanism of a magnetic recording and reproducing apparatus according to the present invention has a tape travel system in which a magnetic tape drawn out of a supply-side tape reel is helically wound around a drum along a lead thereof by tilted guides respectively provided on inlet and outlet sides of the drum and tape guides respectively provided on inlet and outlet sides thereof, passed via a capstan and wound around a takeup side tape reel. A vertical position of the lead of the drum is set equal to that of a lower edge of the tape in a state immediately before the magnetic tape is loaded onto the drum. The magnetic tape is twisted in the middle of the tape travel system in order to cancel difference in tension between upper and lower edges of the magnetic tape when the magnetic tape is loaded onto the drum.

摘要： A recording and reproducing apparatus has an indirect drive arrangement in which the reel turntables are rotated by an existing motor, such as a capstan motor or the like. The reel turntables can pivot about supporting points on a chassis such that they can be moved between large and small cassette driving positions. A drive gear supported on a swing arm and which is driven by a capstan motor, is selectively meshed with one of the driven gears provided on the two reel turntables.

摘要： A tape cassette comprises a case body having a mouth formed in the front portion thereof, a front lid pivotally supported thereon so as to cover the open front side of the case body, and a back lid pivotally joined to the front lid so as to cover a space extending behind the substantially lower half of an exposed portion of a magnetic tape in the mouth. The front lid includes a front wall covering the front opening of the mouth, side walls extending backward from the opposite side edges of the front wall, an upper wall covering the upper opening of the mouth, and a back wall extending downward from the upper wall. The side wall is provided with two guide grooves with two round projections projecting from the inner surface of the side wall being respectively received therein. Each of the two guide grooves has the shape of an arc of a circle having its center at the center of an imaginary circle at one end of the other guide groove. When the front lid is turned toward its opening position, one of the round projections moves first along the corresponding guide groove at the initial stage of turning of the front lid, and then the other round projection moves along the corresponding guide groove at the final stage of turning of the front lid.
