Abstract

PURPOSE:To clean a head without inserting a cleaning cassette by connecting a cleaning tape to the trailing edge of a magnetic tape housed in a cassette tape device. CONSTITUTION:When an photosensor 7 detects a splicing tape 4 connected to the trailing edge of the magnetic tape 3, a take-up reel 1 stops to terminate recording or reproducing the magnetic tape 3. In the case of depressing the cleaning switch of a VTR device even when the photosensor detects the splicing tape 4, the reel does not stop but the cleaning tape 5 is brought into contact with a rotary drum to remove the clogging of the head. When the photosensor detects the splicing tape 6, The take-up reel 1 stops to terminate cleaning the head. Thus, the head can be cleaned without inserting the cleaning cassette.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an audio cassette tape device for recording audio or a visual cassette tape device for recording video and audio.

[Prior Art] Conventionally, audio cassette tape devices that record sound or visual cassette tape devices that record video and audio (hereinafter referred to as VTR tapes) have been known. , recording/playback device (hereinafter referred to as
When used for a long time with a VTR (VTR device), the magnetic material may be slightly scraped, and the scraped magnetic material and dust may damage the VTR.
There was a problem that the head of the device became clogged.

In order to solve this problem, a cleaning cassette is inserted into the VTR device to remove clogging in the head of the recording/reproducing device.

FIG. 2 is a sectional view showing the structure of the cleaning cassette, in which (9) is a cassette housing, (1
) is a take-up reel housed in the cassette housing (9) and rotatably supported.

Further, (8) is a supply reel housed in the cassette housing (9) and rotatably supported, and (5) has its tip connected to the take-up reel (1) and its terminal end connected to the supply reel (8). The take-up reel (1) and the supply reel (
8) is the cleaning tape wound around the

Furthermore, FIG. 3 is a perspective view showing the structure of the cleaning tape (5) in detail. ), the leader tape connected to (7)
is a trailer tape whose leading end is connected to the terminal end of the cleaning tape (5) and whose terminal end is connected to the supply reel (8).

Next, the operation will be explained.

When performing head cleaning, when the cleaning cassette is inserted into the VTR device and the playback button is pressed, the motor rotates the take-up reel (1) to start winding the cleaning tape (5) and the supply reel (8). Rotate and feed the cleaning tape (5).

As a result, the cleaning tape (5) runs while being in contact with the head, and the magnetic material and dust attached to the head are scraped off by the cleaning tape (5).

[Problems to be Solved by the Invention] Since the conventional cleaning cassette is constructed as described above, in order to remove the magnetic material and dust attached to the head, it is necessary to remove the magnetic material and dust that have adhered to the head. Instead, a cleaning cassette must be inserted into the VTR device to clean the head, which is cumbersome.

The present invention was made to solve the above-mentioned problems, and provides a cassette tape device that can clean the head without inserting a cleaning cassette into the recording/playback device, instead of the normally used cassette tape device. The purpose is to obtain.

[Means for Solving the Problems] A cassette tape device according to the present invention includes a magnetic tape for recording video or audio, a first reel connected to the leading end of the magnetic tape, and a first reel connected to the leading end of the magnetic tape. The apparatus is characterized in that it includes a cleaning tape and a second reel connected to the terminal end of the cleaning tape, and the cleaning tape cleans the head.

[Function] The cassette tape device of the present invention usually records video or audio using a magnetic tape, and cleans the head of the recording/reproducing device using a cleaning tape as necessary.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the structure of a VTR tape according to the present invention, in which (1) shows a rotatably supported take-up reel;
2) is a leader tape whose tip is connected to the take-up reel (1).

(3) is a magnetic tape whose tip is connected to the end of the leader tape (2) to record video and audio;
4) is a splicing chive made of a transparent polyethylene film as a detection tape whose tip end is connected to the end of the magnetic tape (3).

Also, the tip of (5) is a splicing chive (4)
A cleaning tape (6) is connected to the end of the cleaning tape to clean the head of the VTR device, and (6) is a splicing chive made of a transparent polyethylene film as a detection tape whose tip is connected to the end of the cleaning tape (5). It is.

Furthermore, (7) has a splicing chive (6) at its tip.
The trailer tape (8) is connected to the terminal end of the trailer tape (7) and is a supply reel rotatably supported.

Next, the operation of this embodiment will be explained.

When recording and playing back video and audio on a VTR tape, V
When a TR tape is inserted into a VTR device, the magnetic tape (3
) is pulled out and wrapped around the rotating drum,
The magnetic tape (
3) to record video and audio on the magnetic tape (3), and to reproduce video and audio from the magnetic tape (3).

At this time, the magnetic tape (3) is wound onto the take-up reel (1) following the leader tape (2), runs while contacting the rotating drum, and the splicing chive (4) connected to the end of the magnetic tape (3) is wound onto the take-up reel (1). When detected by the optical sensor, the take-up reel (1) stops, and recording or reproduction on the magnetic tape (3) ends.

In addition, when cleaning the head of a VTR device, if you press the cleaning switch provided on the VTR device, the cleaning tape (5) will not stop even if the splicing chive (4) is detected by the optical sensor, and the cleaning tape (5) will move onto the rotating drum. Clean the head by touching it.

When the splicing chive (6) is detected by the optical sensor, the take-up reel (1) is stopped and cleaning of the head is completed.

In the above embodiment, a VTR tape is used as the cassette tape device, but the present invention is not limited to this, and may be an audio cassette tape, a micro cassette tape, a digital audio chip, or the like.

Further, in the above-mentioned embodiments, a splicing tube made of a transparent polyethylene film was used as the detection tape, but the invention is not limited to this, and a metal tape or a metal-coated tape may be used.

[Effects of the Invention] As explained above, according to the present invention, since the cleaning tape is connected to the end of the magnetic tape stored in the cassette tape device, the head can be replaced without inserting a cleaning cassette in place of the cassette tape device. Cleaning can be performed, and the trouble of replacing the cassette tape device and cleaning cassette can be omitted.
