Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention relates to a cassette head cleaner, and more particularly to a sounding body with a timer. By installing, let the user recognize the sound from this sounding body as an alarm, Head cleaning function for cleaning the magnetic head The present invention relates to a new improvement for preventing abrasion of a cord.

[0002]

[Prior art]

  As a cassette head cleaner of this type that has been conventionally used, Patent Document 1 Although not specifically mentioned as a non-patent document, generally, as a first conventional example, Built-in leaning tape, rotate this cleaning tape for about 30 seconds I was cleaning the magnetic head.   As a second conventional example, a felt containing a little moisture is placed in the casing. Then, the felt is pressed against the magnetic head by the force of the rotating reel, and I was cleaning the surface of the pad.

[0003]

[Problems to be solved by the device]

  Since the conventional cassette head cleaner was configured as described above, the following There was such a problem.   That is, in the case of the first conventional example, the length of the cleaning tape is 30 seconds long. Since it is configured, the drive of the cleaning tape automatically stops after 30 seconds. It should stop, but the cassette deck that is often used is auto-reverse. Therefore, if the operator does not notice, it will move endlessly back and forth, and the wear of the magnetic head will progress. Therefore, the sound quality was sometimes degraded.   Further, in the case of the second conventional example, the gear provided on each reel supports the felt. It is configured to mesh with the gear of the material so that sound is always produced, but the operator If you don't care, press the magnetic head for a few minutes over 30 seconds to Doing a cleaning operation may damage the magnetic head. It was

[0004]   The present invention has been made to solve the above problems, and in particular, a timer By attaching a sound generator with a built-in sound alarm to the user And the head cleaning function to clean the head. Providing a cassette head cleaner designed to prevent head wear due to excess The purpose is to do.

[0005]

[Means for Solving the Problems]

  The cassette head cleaner according to the present invention has the same shape and dimensions as the cassette tape. And has a head cleaning function body for cleaning at least the magnetic head. A cassette head cleaner comprising a casing having the above-mentioned casing. Inside, there is a sounding body with a timer and a switch connected to the timer. By turning on the switch, the timer will expire after a predetermined time The sounding body is configured to sound, and the sounding body is the casing. Provided on the side of the switch, the switch comprises a push switch, When the push button of the switch is pushed in and turned on, the push button is pushed to the side of the side part. The switch does not stick out from the wall, and the switch is a slide switch. The head cleaning function body is a cleaning unit. The head cleaning function body is a head unit. It is composed of a felt.

[0006]

[Embodiment of device]

  Preferred embodiments of a cassette head cleaner according to the present invention will be described below with reference to the drawings. Will be described.   In FIG. 1, reference numeral 1 indicates the same shape and size as a commercially available cassette tape. And a casing that is a standard and forms a cassette head cleaner. First and second reels 2 and 3 are rotatably provided in the housing 1. In addition, this The cassette head cleaner itself is commercially available.

[0007]   Gears 4 and 5 are provided on the outer circumferences of the reels 2 and 3, respectively. An idle gear 6 is provided so as to be able to mesh with each gear 4, 5.   At the end portion of the holding body 7 provided on the idle gear 6 and having a generally U-shape as a whole. Is provided with a head felt 10 for a magnetic head.

[0008]   The holding body 7 is made of a flexible elastic resin or the like, and has the first and second gears 4 When the idle gear 6 is rotated by the rotation of 5, the holding body 7 is moved forward. When the head felt 10 is pressed to the front side, It is configured to clean the surface.   The felt 10 for the head is magnetic when used in a slightly moistened state in advance. It is effective for removing dust etc. adhering to the air head surface. The belt 10 constitutes a cleaning function body 20 for cleaning the magnetic head. For cleaning pinch rollers (not shown) provided at both corners of the casing 1. A pair of pinch roller felts 21 and 22 also constitute the cleaning function body 20. is doing. That is, the above-mentioned structure is a well-known structure.

[0009]   Next, inside the casing 1, a small box-shaped sounding body 30 is installed. This sounding body 30 includes a drive circuit and a push-button that have a timer (not shown). Switch 31 or a slide switch, and a spin switch (not shown). It is composed of The switch 31 is not limited to a mechanical switch, A one-pulse operation type using an electronic switch such as a semiconductor can also be used.

[0010]   The sounding body 30 is arranged at a side position of the casing 1. When the push button 32 of the 0 switch 31 is not pushed in (that is, when it is OFF) It projects outward from the side wall surface 1a of the side portion of the casing 1.   The push button 32 is pushed in to turn on the switch 31 to activate the sounding body 30. When the push button 32 is pushed, the push button 32 is flush with or inward with the side wall surface 1a. It is configured so as not to project outward from the side wall surface 1a. For driving the sound generator 30 Although not shown, the battery is provided in a space inside the casing 1.

[0011]   Next, the operation will be described. First, the push button 3 of the switch 31 of the sounding body 30 When 2 is pressed in, the timer of the sound generator 30 is turned on and the time counting starts. Be done.   In the above-mentioned state, the casing 1 is mounted on a cassette deck such as a vehicle or a tabletop type (shown in the figure). If you insert it inside, the reels 2 and 3 rotate and the head felt 10 becomes magnetic. The head (not shown) is pressed to remove dust on the head surface of the magnetic head.

[0012]   The felts 21 and 22 for the pinch rollers use the casing 1 as a cassette deck. At the same time as inserting it into the key, it will come in contact with a pinch roller (not shown) to remove dust. Be seen.   In the above-mentioned state, when a predetermined time (for example, 30 seconds) elapses, the timer When the drive circuit operates, the speaker (not shown) produces sound. An alarm is issued to the user and the casing 1 which is the cassette head cleaner is taken out. The sushi can be prompted to the user.   Therefore, the cassette head cleaner cannot be removed by the sound from the sound generator 30. By pulling it out from the storage deck, it is possible to prevent abrasion of the magnetic head. it can.

[0013]   In addition, the cleaning function body 20 in FIG. As mentioned above, a well-known cleaning tape is wound around each reel 2 and 3 and Cleaning the magnetic head by rotating the leaning tape Even in the case of such a configuration, it is possible to obtain the same operational effects as those in FIG. 1 described above.

[0014]

[Effect of device]

  The cassette head cleaner according to the present invention is constructed as described above. The following effects can be obtained.   In other words, the cassette head cleaner has a switch and a timer. Since it has a built-in body, it can be placed inside the cassette deck with this switch turned on. When inserted, an alarm is generated by a sound after a predetermined time, and the magnetic head It is possible to prevent abrasion of the product.
