Abstract

The magnetic head cleaning mechanism of the present disclosure includes: a transmission gear connected to a driving source; a cam gear connected to mesh with the transmission gear; a cutting mechanism that cuts the power transmission of the cam gear and the transmission gear if a magnetic tape wound state is reached; a toothless gear connected to mesh with the transmission gear; a cleaning gear connected to mesh with the toothless gear; a deceleration mechanism that decelerates and transmits power from the transmission gear to the cleaning gear; a cleaning arm connected to the cleaning gear and having a cleaning member that cleans a magnetic head; and an intermittent transmission mechanism that cuts the power transmission of the toothless gear and the cleaning gear until the tape wound state is reached and that starts the transmission in a case where the tape wound state is reached.

Dependent claims

A magnetic head cleaning device comprising:

a transmission gear that is connected to a driving source;
a cam gear that is connected to mesh with the transmission gear;
a cutting structure that cuts power transmission of the cam gear and the transmission gear when a magnetic tape wound state is reached, the cutting structure including a transmission large gear provided on one side of the transmission gear and having a cylindrical surface in a partial range;
a tooth-missing gear that is connected to mesh with the transmission gear;
a cleaning gear that is connected to mesh with the tooth-missing gear;
a gear train that decelerates and transmits power from the transmission gear to the cleaning gear;
a cleaning arm that is connected to the cleaning gear and includes a cleaning member that cleans a magnetic head;
and
an intermittent transmission structure that cuts power transmission of the tooth-missing gear and the cleaning gear until the magnetic tape wound state is reached and that starts the transmission in a case where the magnetic tape wound state is reached, the intermittent transmission structure including a tooth-missing small gear provided on one side of the tooth-missing gear and having a cylindrical surface in a partial range.
