DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cylinder cleaning mechanism in a recording / reproducing apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing a deck portion of a recording / reproducing apparatus provided with a cylinder cleaning mechanism according to an embodiment of the present invention. FIG. 2 shows an operation procedure of the cylinder cleaning mechanism in the recording / reproducing apparatus according to the embodiment. FIG. 3B is a partial plan view showing a state where the cleaning operation is instantaneously separated from the cleaning operation, and FIG. 3C is a partial plan view showing a state where cleaning is performed again.

This recording / reproducing apparatus, as shown in FIG.
Head 21 for reading cassette tape records on deck 1
A pair of left and right guide grooves 3, 3 provided near the left and right sides of the cylinder 2;
A loading arm 4, 4 for moving in the guide grooves 3, 3 is provided. In the cylinder cleaning mechanism of the present embodiment, the loading arm 4 contacts the loading arm 4 by moving forward and backward at a position near the end of the guide groove 3 on the left side of the deck 1. A contact piece 52 that is pushed and pivotally attached to the base 51 near the guide groove 3 on the deck 1, an arm 53 formed integrally with the contact piece 52, and a tip of the arm 53 When the contact piece 52 is pivotally attached to the loading arm 4 and is pressed against the loading arm 4, the contact piece 52 rotates together with the arm section 4 in a clockwise direction and contacts the head 21 of the cylinder 2.
And a cleaning roll 54 for cleaning the head.

Further, an operation unit (not shown) such as a remote controller of the recording / reproducing apparatus drives the cylinder 2 in rotation and controls the loading arm 4 to control the loading of the cylinder 2 by the cleaning roll 54 of the head cleaner 5.
A cleaning key (not shown) for driving the head 21 for cleaning is provided. When the cleaning key is turned on, the loading arm 4 is brought into contact with the contact piece 52 of the head cleaner 5 for about 30 seconds as shown in FIGS. The cylinder 2 is moved forward and backward in the vicinity, and the intermittent and continuous contact of the loading arm 5 with the contact piece 52 causes the cleaning roll 54 to move the cylinder 2 through the arm 53.
The head 21 is configured to be intermittently and continuously cleaned. Moreover, while the head 21 of the cylinder 2 is being cleaned by the cleaning roll 54 of the head cleaner 5, a display indicating that the cleaning is being performed is displayed on a display screen (not shown) of the recording / reproducing apparatus.

Next, the operation procedure of the cylinder cleaning mechanism in the recording / reproducing apparatus of the present embodiment configured as described above will be described with reference to the flowchart of FIG. First, it is determined whether the cleaning key is turned on to start cleaning (step 1). If cleaning is started, the drum of the cylinder 2 rotates (step 2), and the loading arm 4 is moved to the vicinity of the end of the guide groove 3. The contact arm 52 of the head cleaner 5 is intermittently and continuously pushed by the loading arm 4 and the head 21 of the cylinder 2 is cleaned by the cleaning roll 54 via the arm 53 (step 3). . Then, it is determined whether or not the cleaning time has elapsed for 30 seconds (step 4). If the cleaning time has not elapsed, the cleaning is continued, and after the lapse, the cleaning ends.

As described above, according to the cylinder cleaning mechanism in the recording / reproducing apparatus of the present embodiment, the head 21 of the cylinder 2 can be easily cleaned without using a cleaning tape, and the cost can be reduced. In addition, since the cleaning can be performed for 30 seconds, the head 21 of the cylinder 21 can be sufficiently cleaned, and the cleaning can be performed without the magnetic tape, so that the magnetic tape is not damaged. In this embodiment, the cleaning time is 30 seconds. However, the present invention is not limited to this. For example, cleaning may be performed for several tens of seconds, such as 40 seconds.

[0014]

As described above, according to the first aspect of the present invention, the loading arm is disposed near the end of the guide groove on the deck of the recording / reproducing apparatus, and the loading arm moves forward and backward near the end of the guide groove. By doing so, it has a head cleaner that contacts the loading arm and is pressed to clean the cylinder head.
The cylinder head can be easily cleaned without using a cleaning tape, and the cost can be reduced. In addition, the cylinder head can be sufficiently cleaned, and the cleaning can be performed with the magnetic tape removed, so that the magnetic tape is not damaged.

According to the second aspect of the present invention, the head cleaner has its base portion pivotally connected to a portion of the deck near the guide groove so as to be in contact with the loading arm. Since a cleaning roll is provided which rotates by contacting the loading arm and contacts the head of the cylinder to clean the head, the structure is extremely simple, and the guide groove moves forward and backward near the end of the guide groove. By the contact of the contact piece of the loading arm, the cleaning roll surely comes into contact with the cylinder head, and the cylinder head can be cleaned well.

According to the third aspect of the present invention, a cleaning key is provided for operating the operating section of the recording / reproducing apparatus to rotate the cylinder and controlling the loading arm to drive the head of the cylinder for cleaning with the head cleaner. , The cylinder head can be automatically cleaned with a single touch simply by pressing the cleaning key.
According to the invention described in claim 4, the loading arm moves forward and backward near the end of the guide groove for several tens of seconds while contacting the contact piece of the head cleaner by turning on the cleaning key. Because the cylinder head is intermittently and continuously cleaned with the cleaning roll by contacting the piece, the cylinder head can be cleaned for a relatively long time compared to the conventional cylinder head cleaning, Good cleaning can be achieved over the entire cylinder head.

According to the fifth aspect of the present invention, while the head of the cylinder is being cleaned by the head cleaner on the display screen of the recording / reproducing apparatus, the display indicating that the cylinder is being cleaned is displayed. Can be determined at a glance, and there is no risk of malfunction such as insertion of a cassette tape during the cleaning.
