BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a cleaning device for a recording and/or reproducing apparatus employing a magnetic tape as a recording medium. More particularly, it relates to a device for cleaning a magnetic head mounted on a rotary drum about which is placed a magnetic tape and which constitutes a rotary head unit.
BACKGROUND ART
Heretofore, a recording and/or reproducing apparatus, employing a magnetic tape as a recording medium, and configured for recording and/or reproducing information signals by a rotary head device having a rotary drum in turn carrying a magnetic head, is in widespread use.
In the present recording and/or reproducing apparatus, employing the rotary head, a magnetic tape is placed obliquely around the rotary drum carrying the magnetic head of the rotary head device and is run while running the magnetic head in rotation for establishing relative sliding contact between the magnetic tape and the magnetic head for recording and/or reproducing information signals. At this time, the information signals are recorded on a recording track obliquely formed relative to the longitudinal direction of the magnetic tape.
In this sort of the recording and/or reproducing apparatus, since the magnetic head is perpetually in sliding contact with the magnetic head during recording and/or reproduction of information signals, magnetic powder debris or dust and dirt peeled off from the magnetic tape becomes deposited on the magnetic head if recording and/or reproduction is continued for prolonged time. If the magnetic powders or dust and dirt become affixed to the magnetic head, recording and/or reproducing characteristics for information signals are deteriorated. For preventing such deterioration in the recording and/or reproducing characteristics, it is necessary to clean the magnetic head periodically.
Thus, the recording and/or reproducing apparatus employing the rotary head unit is provided with a cleaning unit for cleaning the magnetic head. This cleaning unit is constructed and designed so that the magnetic head mounted on the rotary drum may be cleaned by bringing a cleaning member into sliding contact with the outer peripheral surface of the rotary drum carrying the magnetic head of the rotary head unit.
DISCLOSURE OF THE INVENTION
It is an object of the present invention to provide a cleaning device for a recording and/or reproducing apparatus employing a magnetic tape as a recording medium whereby a magnetic head of a rotary head unit can be cleaned easily and reliably.
It is another object of the present invention to provide a cleaning device capable of performing cleaning while assuring protection of the magnetic head of the rotary head unit.
It is another object of the present invention to provide a cleaning device which is durable and which enables reliable cleaning over an extended period of time.
A cleaning device for a recording and/or reproducing apparatus for a magnetic tape, proposed for accomplishing the above objects, includes a rotary head device having a rotary drum carrying a magnetic head, a cleaning member for being abutted against at least the magnetic head of the magnetic head device for cleaning the magnetic head, and actuating means for causing at least the cleaning member to be abutted against at least the magnetic head in the rotating state of the rotary head device.
The cleaning device according to the present invention includes a tape loading mechanism for loading the magnetic tape on the rotary head device. The actuating mechanism for causing the cleaning member of the cleaning device to be abutted against the magnetic head causes the cleaning member to be abutted at least against the magnetic head in the rotating state of the rotary drum prior to the loading of the magnetic tape on the rotary head device by at least the tape loading mechanism.
The actuating mechanism for causing the cleaning member to be abutted against the magnetic head releases abutment of the cleaning member against the magnetic head when the magnetic tape is loaded by the tape l
