Abstract
In a magnetic tape device, a tape cassette moving table 4 is placed between a pair of right and left guide plates 3a and 3b so as to be movable forward and backward (a and b). Rocking levers 8 which are engaged with the moving table 4, and a rotating cam 9 which is forward and reversely rotated by a driving source are interlockingly connected to each other via a slide plate 26. The rocking levers 8 are swung forward and backward (c and d) by the driving source via the rotating cam 9 and the slide plate 26 to move the moving table 4 forward and backward (a and b) between a cassette inserting position A and a cassette placing position B.
Claims12
A magnetic tape device comprising:
- a pair of right and left guide plates;
- a tape cassette moving table placed between said pair of right and left guide plates to be movable forward and backward;
- a rocking lever engaged with said moving table;
- a driving member;
- a rotating member which is forward and reversely rotated by said driving member;
- and
- an interlocking mechanism by which said driving member and said rotating member are interlockingly connected to each other;
- wherein said rocking lever is swung by said driving member via said rotating member and said interlocking mechanism to move said moving table forward and backward between a cassette inserting position and a cassette placing position;
- wherein said interlocking mechanism includes a slide plate that has a slide plate body which is placed to be slidable along one of said guide plates and a bent piece which is bent into a substantially L-like shape from a lower edge of said slide plate body to elongate toward said rotating member;
- and
- wherein a rack which is engaged with a pinion formed on said rotating member is formed on said bent piece, an engaging hole which is to be engaged with an engaging pin protruding from said rocking lever is opened in said slide plate body, a lock lever which is engageable with said engaging pin is pivotally attached to said slide plate body, said rocking lever is backward swung to backward move said moving table toward the cassette placing position by backward sliding said slide plate to cause a peripheral portion of said engaging hole to be engaged with said engaging pin, and said rocking lever is forward swung to forward move said moving table toward the cassette inserting position by forward sliding said slide plate to cause said lock lever to be engaged with said engaging pin.

A magnetic tape device comprising:
- a pair of right and left guide plates;
- a tape cassette moving table placed between said pair of right and left guide plates to be movable forward and backward;
- a rocking lever engaged with said moving table;
- a driving member;
- a rotating member which is forward and reversely rotated by said driving member;
- and
- an interlocking mechanism by which said driving member and said rotating member are interlockingly connected to each other;
- wherein said rocking lever is swung by said driving member via said rotating member and said interlocking mechanism to move said moving table forward and backward between a cassette inserting position and a cassette placing position;
- wherein said interlocking mechanism has a slide plate which is placed to be slidable along one of said guide plates, and which is to be engaged respectively with said rotating member and said rocking lever;
- and
- wherein a lock lever which is engageable with said engaging pin is pivotally attached to said slide plate body, a lock groove is formed in a tip end portion of said lock lever, and, under a state where said lock lever is swung and said lock groove is opposed to said engaging pin across a gap of a predetermined distance, said slide plate is forward slid to cause said lock groove to be engaged with said engaging pin, thereby forward swinging said rocking lever to forward move said moving table toward the cassette inserting position.
