Abstract
Abstract An automatic tape loading type reproducing apparatus uses a guide drum having at least one rotating head. A cassette contains a supply reel and a take-up reel with a tape extending therebetween. The tape is drawn from the cassette and loading along a specific path in wrapping contact with the guide drum, when the tape is advanced in a forward direction and returned to the cassette when the tape is driven in the reverse direction. A driving motor rotates in a forward direction to drive the loading means and in the reverse direction to drive the loading means. A tape driving means causes tape travel during normal reproduction and terminates the tape travel driving during still picture reproduction. A switch is actuated during still picture reproduction to cause the driving motor to rotate in the reverse direction for a specific time and thereafter to cause the driving motor to rotate in the forward direction for at least the same specific time. As a result of the actuation of the switch, at the time of still picture reproduction the tape driving means is precluded from operation and the tape is taken up on the take-up reel. The tape is paid out from the supply reel intermittently in response to the forward operation during loading.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
295 words
An automatic tape loading type reproducing apparatus comprising: a guide drum having at least one rotating head; loading means for operating with a cassette having a supply reel and a take-up reel with tape wound thereon, said loading means including means for drawing the tape from the cassette and loading the drawn out tape into a path in wrapping contact with the guide drum responsive to a loading operation in a forward direction, and for storing the tape in the cassette responsive to an operation in the reverse direction; means comprising a driving motor selectively operating in a forward direction to drive the loading means in a forward direction and rotating in a reverse direction to drive the loading means in the reverse direction operation; means for imparting a torque for urging the take-up reel to tension the tape in its taking up direction; tape driving means for causing tape travel during normal reproduction and for terminating the tape travel during still picture reproduction; a switch means for momentary actuation during the still picture reproduction; and electrical circuit means operating in response to each of the momentary actuations of the switch to cause the driving motor to rotate briefly in a reverse direction for a specific interval of time and thereafter to rotate in a forward direction for at least said specific interval of time, whereby actuation of the switch during still picture reproduction causes the tape driving means to cease normal operation, to take up a short section of the tape on the take-up reel in response to the reverse direction operation of the loading means and to pay out the tape from the supply reel so that the tape is shifted intermittently in response to the forward direction operation of the loading means.
Claim 2
Dependent Claim
295 words
An automatic tape loading type reproducing apparatus comprising: a guide drum having at least one rotating head; loading means for operating with a cassette having a supply reel and a take-up reel with tape wound thereon, said loading means including means for drawing the tape from the cassette and loading the drawn out tape into a path in wrapping contact with the guide drum responsive to a loading operation in a forward direction, and for storing the tape in the cassette responsive to an operation in the reverse direction; means comprising a driving motor selectively operating in a forward direction to drive the loading means in a forward direction and rotating in a reverse direction to drive the loading means in the reverse direction operation; means for imparting a torque for urging the take-up reel to tension the tape in its taking up direction; tape driving means for causing tape travel during normal reproduction and for terminating the tape travel during still picture reproduction; a switch means for momentary actuation during the still picture reproduction; and electrical circuit means operating in response to each of the momentary actuations of the switch to cause the driving motor to rotate briefly in a reverse direction for a specific interval of time and thereafter to rotate in a forward direction for at least said specific interval of time, whereby actuation of the switch during still picture reproduction causes the tape driving means to cease normal operation, to take up a short section of the tape on the take-up reel in response to the reverse direction operation of the loading means and to pay out the tape from the supply reel so that the tape is shifted intermittently in response to the forward direction operation of the loading means.
Claim 3
Dependent Claim
94 words
An automatic tape loading type reproducing apparatus as claimed in claim 1, in which said loading means comprises a lever means for drawing the tape from the cassette, and a rotatable ring means encircling the guide drum, said rotatable ring loading the drawn out tape along a predetermined path which is in contact with the guide drum; and means for operating said driving motor in normal and reverse directions responsive to signals in said electrical circuit means in order to rotate the rotatable ring in normal and reverse directions during the still picture reproduction.
Claim 4
Dependent Claim
61 words
An automatic tape loading type reproducing apparatus as claimed in claim 1, and means in said electrical circuit means for applying a voltage to turn the driving motor in a reverse direction during a predetermined period and thereafter applying a voltage to turn the driving motor in a normal direction during a period which is slightly longer than said predetermined period.
Claim 5
Dependent Claim
188 words
An automatic tape loading type reproducing apparatus as claimed in claim 1, in which said electrical circuit means comprises a differentiation circuit means for forming a pulse responsive to a closing of said switch, a first multivibrator triggered by the pulse from the differentiation circuit means to produce an output signal having a first predetermined pulse width, a second multivibrator triggered by the pulse from the differentiation circuit means to produce an output signal having a second predetermined pulse width which is longer than the first predetermined pulse width, a first relay means operated responsive to the output signal of the first multivibrator during the period of the first predetermined pulse, a second relay means operated responsive to the output signal of the second multivibrator during the second predetermined pulse, and a switching circuit means including relay contacts of the first and the second relays for switching the driving motor to rotate in a reverse direction during the period of the first predetermined pulse and to rotate in a normal direction during the period of the second predetermined pulse after the end of the first predetermined pulse period.
Claim 6
Dependent Claim
35 words
An automatic tape loading type reproducing apparatus as claimed in claim 4, in which the period of said second predetermined pulse is more than twice as long as the period of the first predetermined pulse.
Claim 7
Dependent Claim
38 words
An automatic tape loading type reproducing apparatus as claimed in claim 1, in which the tape is shifted by one intermittent operation over a distance which is shorter than the distance between adjacent tracks recorded on the tape.
