Abstract
Abstract A cassette holding device for a tape recorder wherein the shock resistance thereof can be assured sufficiently with a simple construction during transportation and during normal use of the tape recorder and protection of a cassette holder, capstan shafts and a tape cassette and reduction in cost and facility in use of the entire tape recorder can be attained. The device comprises an ejecting member which holds, when it is at advanced position, an arresting member to an advanced position in which a cassette holder can receive therein a tape cassette inserted into the tape recorder. When the arresting member is at a retracted position, the ejecting member is prevented from moving from a retracted position to the advanced position, but when the arresting member is moved form the retracted to the advanced position, the ejecting member is allowed to move from the retracted to the advanced position to eject a tape cassette from the tape recorder.

Claim 1
Independent Claim
249 words
A cassette holding device for a tape recorder, comprising a cassette holder for removably receiving a tape cassette therein, said cassette holder being coupled to a base plate for movement between an operative position in which recording on or reproduction from a tape within a tape cassette received therein can be achieved and a rest position, spring means for urging said cassette holder toward the operative position, an arresting member mounted on said cassette holder for selective back and forth movement between an advanced position and a retracted position, stationary arresting means located on said base plate for engagement with said arresting member at the advanced position to arrest said cassette holder to the rest position, an ejecting member coupled to an end of said spring means and mounted for back and forth movement between an advanced position and a retracted position on said cassette holder, said ejecting member being retracted by an inserting force of a tape cassette inserted into said cassette holder to disengage said arresting member from said stationary arresting means while accumulating a spring force in said spring means, said ejecting member being advanced, when allowed, by the accumulated spring force to push back the tape cassette in a direction to unload the tape cassette, and means on said ejecting member for limiting, when said ejecting member is at the advanced position, movement of said arresting member away from the advanced position to maintain the engagement of said arresting member with said stationary arresting means.

A cassette holding device for a tape recorder, comprising a cassette holder for removably receiving a tape cassette therein, said cassette holder being coupled to a base plate for movement between an operative position in which recording on or reproduction from a tape within a tape cassette received therein can be achieved and a rest position, spring means for urging said cassette holder toward the operative position, an arresting member mounted on said cassette holder for selective back and forth movement between an advanced position and a retracted position, stationary arresting means located on said base plate for engagement with said arresting member at the advanced position to arrest said cassette holder to the rest position, an ejecting member coupled to an end of said spring means and mounted for back and forth movement between an advanced position and a retracted position on said cassette holder, said ejecting member being retracted by an inserting force of a tape cassette inserted into said cassette holder to disengage said arresting member from said stationary arresting means while accumulating a spring force in said spring means, said ejecting member being advanced, when allowed, by the accumulated spring force to push back the tape cassette in a direction to unload the tape cassette, and means on said ejecting member for limiting, when said ejecting member is at the advanced position, movement of said arresting member away from the advanced position to maintain the engagement of said arresting member with said stationary arresting means.
Claim 3
Dependent Claim
294 words
A cassette holding device for a tape recorder, comprising a cassette holder for removably receiving a tape cassette therein, said cassette holder being coupled to a base plate for movement between an operative position in which recording on or reproduction from a tape within a tape cassette received therein can be achieved and a rest position, spring means for urging said cassette holder toward the operative position, an arresting member pivotally mounted on said cassette holder for selective back and forth movement between an advanced position and a retracted position, stationary arresting means located on said base plate for engagement with said arresting member at the advanced position to arrest said cassette holder to the rest position, an ejecting member coupled to an end of said spring means and mounted for back and forth movement between an advanced position and a retracted position on said cassette holder, said ejecting member being retracted by an inserting force of a tape cassette inserted into said cassette holder to disengage said arresting member from said stationary arresting means while accumulating a spring force in said spring means, said ejecting member being advanced, when allowed, by the accumulated spring force to push back the tape cassette in a direction to unload the tape cassette, and means for preventing, when said arresting member is at the retracted position in which said arresting member is disengaged from said stationary arresting means, movement of said ejecting member away from the retracted position toward the advanced position and for allowing, when said arresting member is advanced to the advanced position via the movement of said ejecting member in which said arresting means engages with said stationary arresting means, movement of said ejecting member away from the retracted position to the advanced position.

A cassette holding device for a tape recorder, comprising a cassette holder for removably receiving a tape cassette therein, said cassette holder being coupled to a base plate for movement between an operative position in which recording on or reproduction from a tape within a tape cassette received therein can be achieved and a rest position, spring means for urging said cassette holder toward the operative position, an arresting member pivotally mounted on said cassette holder for selective back and forth movement between an advanced position and a retracted position, stationary arresting means located on said base plate for engagement with said arresting member at the advanced position to arrest said cassette holder to the rest position, an ejecting member coupled to an end of said spring means and mounted for back and forth movement between an advanced position and a retracted position on said cassette holder, said ejecting member being retracted by an inserting force of a tape cassette inserted into said cassette holder to disengage said arresting member from said stationary arresting means while accumulating a spring force in said spring means, said ejecting member being advanced, when allowed, by the accumulated spring force to push back the tape cassette in a direction to unload the tape cassette, and means for preventing, when said arresting member is at the retracted position in which said arresting member is disengaged from said stationary arresting means, movement of said ejecting member away from the retracted position toward the advanced position and for allowing, when said arresting member is advanced to the advanced position via the movement of said ejecting member in which said arresting means engages with said stationary arresting means, movement of said ejecting member away from the retracted position to the advanced position.
