Description

[Technical field]

[0001] The present invention relates to a protector for a record center label for protecting a center label provided at the center of a record, and a method for protecting the record center label. [Background technology]

[0002] In recent years, analog records have become more and more popular. The main material of records is polyvinyl chloride. Polyvinyl chloride is easily negatively charged, so dust and dirt easily adhere to it. Therefore, in order to keep records in good condition, it is recommended that you wash them regularly.

[0003] By the way, a circular sticker is attached to the center of a record, which lists information such as the rotation speed, the title of the song, the musician, the record company name, etc. This sticker is called the center label (also called a label or label), and often has a unique design like the jacket that holds the record. Center labels are often made of paper, which means that there is a risk of the ink bleeding, warping, or damage to the center label when the record is played or when the record is washed.

[0004] Patent Document 1 discloses a record cleaning tool that covers the label portion formed in the centre of a record, the tool comprising a set of cover members that cover both sides of the label portion of the record, a sealant that seals between the cover members and the record, a male screw member, and a female screw member that screws into the male screw member, the cover members have sealant attached along their outer circumference and have a central through hole that coincides with the centre hole of the record, and the male screw member is inserted through the centre hole of the record and the cover members at a position where the centre hole of the record is aligned with the through hole in the cover members, and the female screw member is screwed into the set of cover members to clamp the record.

[0005] Non-Patent Document 1 discloses an acrylic protector for protecting the paper label portion at the center of a record from water when the record is washed with water. [Prior art documents] [Patent documents]

[0007] [Non-Patent Document 1] http: / / www.nagaoka.co.jp / item / clp02.htm DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0008] As mentioned above, record center labels often have unique designs. For records to be valuable as antiques, it is important that not only the record itself is in good condition, but also that the center label is in good condition.

[0009] Incidentally, when playing records, a record player equipped with a tone arm having a record needle at the tip is often used. Whether manual or automatic, a record is played by lowering the needle onto a record that is rotating on the turntable of the record player. Generally, the needle moves from the outside to the inside of the record as it rotates. When the needle reaches the innermost circumference (groove) of the record, depending on the condition of the record player, needle, or record, there is a risk that the needle may penetrate into the center label and damage it.

[0010] The devices disclosed in Patent Document 1 and Non-Patent Document 1 are for removing dust and dirt from the grooves of a record by washing with water. Therefore, they are not intended to protect the center label other than to prevent it from getting wet when washing with water. Furthermore, these documents do not disclose or suggest the idea or concept of preventing damage to the center label when a record is played.

[0011] The present invention has been made in consideration of the above circumstances, and has as its object to provide a protector for a record center label and a method for protecting a record center label that can prevent damage to the center label by a record needle when playing a record. [Means for solving the problem]

[0012] The present invention has the following configuration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The protector for record center labels (hereinafter referred to as "protector") 100 according to this embodiment has a circular shape in a plan view. The protector 100 is removably attached so as to cover the upper surface 300a of the center label 300. It is also preferable that the protector 100 is in close contact with a part of the upper surface 300a of the center label 300.

[0019] As the resin, a soft resin is preferably used, and thermoplastic resins such as soft polyvinyl chloride, polyethylene, polystyrene, etc., thermoplastic elastomers, etc. are preferably used. Furthermore, the rubber may be natural rubber or synthetic rubber, and soft rubber is preferably used. However, the resin or rubber is not limited to these, and hard resins and hard rubbers can also be used. In this embodiment, the protector 100 is made of soft polyvinyl chloride. Additionally, the protector 100 is preferably transparent or translucent, but may be opaque.

[0020] The thickness (PT) of the protector 100 is 0.5 mm to 1.5 mm. Moreover, the area (PA) of the upper surface portion 100a of the protector 100 is equal to or larger than the area (LA) of the upper surface portion 300a of the center label 300. It is preferable that the area (PA) is larger than the area (LA). It is also preferable that the diameter of the protector 100 is larger than the diameter of the center label 300 and smaller than the diameter of the innermost circumference (not shown) of the record 200. In particular, it is preferable that the diameter of the protector 100 is slightly larger than the diameter of the center label 300.

[0021] Further, a hole 110 is provided in the center 100b of the protector 100 for allowing the protector 100 to be detachably inserted into a center spindle 420 protruding from a center 400a of a turntable 410 of the record player 400. The hole 110 has a circular shape in a plan view. The area (PA) of the upper surface portion 100a includes the area corresponding to the space on the inner periphery side of the hole 110.

[0022] The record 200 has a groove 210. Also, a center hole 220 is provided in the center 200b of the record 200, through which a center spindle 420 is removably inserted on the inner periphery side and through which the record 200 is placed on a turntable 410. A center label 300 made of paper, for example, is attached or pressed into the central area 200a of the record 200. A hole 320 is provided in the central portion 300b of the center label 300 for removably inserting a center spindle 420. The hole 320 has a circular shape in a plan view.

[0023] It is preferable that the diameter (Φ1) of the hole 110 and the diameter (Φ2) of the hole 320 of the center label 300 satisfy the relationship diameter (Φ1)≦diameter (Φ2), and it is more preferable that the diameter (Φ1) is slightly smaller than the diameter (Φ2). However, the diameter (Φ1) can be changed as appropriate within a range in which the protector 100 can be inserted onto the center spindle 420 when the record 200 is set in the record player 400, and the protector 100 can be attached so as to cover the upper surface 300a of the center label 300.

[0024] In this embodiment, the protector 100, record 200, and center label 300 are assumed to be LP size. However, they may of course be of sizes other than LP size (e.g. SP size, EP size).

[0025] The record player 400 has a turntable 410, a center spindle 420, and a manual tone arm 450 having at its tip a cartridge 440 with a record needle 430 attached thereto. The turntable 410 is rotated by an internal drive motor (not shown). The center spindle 420 is a protrusion for positioning the record 200 at the center of the rotation axis. The phonograph needle 430 picks up an audio signal from a groove 210 formed in the record 200.

[0026] The operation of the above configuration will now be described.

[0027] First, the protector 100 is attached to the record 200. Specifically, the protector 100 is attached to the record 200 so that the protector 100 covers the entire top surface 300a of the center label 300 and so that the hole 110 of the protector 100 and the center hole 220 of the record 200 are aligned (see step S610 in FIG. 6).

[0028] Then, the record 200 with the protector 100 attached is set on the turntable 410 of the record player 400 via the center spindle 420 (step S620), which allows the record to be played back.

[0029] In this embodiment, the protector 100 is attached to the record 200, and then the record 200 is set on the turntable 410. However, the protector 100 may be attached to the record 200 after the record 200 is set on the turntable 410.

[0030] Thereafter, the turntable 410 is rotated, the tone arm 450 is manually moved onto the record 200, and the phonograph needle 430 is lowered into the desired groove 210 of the record 200, and playback of the record begins (step S630).

[0031] Then, when the phonograph needle 430 reaches the innermost periphery of the record 200, the tone arm 450 is manually moved upward to separate the phonograph needle 430 from the record 200, thereby ending the record playback (step S640).

[0032] Normally, the needle does not move any further inward than the innermost periphery of the record. However, depending on the condition of the record player, the needle, or the record, the needle may move further inward than the innermost periphery of the record, i.e., to the center label. Even in such a case, if the protector 100 is attached to the record 200, the phonograph needle 430 will come into contact with the outer periphery 100c of the protector 100, not with the outer periphery 300c of the center label 300. The outer periphery 100c of the protector 100 blocks further (inward) movement of the phonograph needle 430, thereby preventing the phonograph needle 430 from coming into contact with the outer periphery 300c of the center label 300 or penetrating into the center label 300. Furthermore, when putting record 200 away into its jacket, protector 100 can be simply removed from record 200. In this embodiment, protector 100 is made of soft polyvinyl chloride. Therefore, protector 100 can be easily removed from record 200 without damaging record 200.

[0033] In this way, the protector 100 of this embodiment can prevent the phonograph needle 240 from entering the center label 300 or coming into contact with the outer periphery 300c of the center label 300 simply by attaching it to the top surface 300a of the center label 300. This allows the protector 100 to prevent damage to the center label 300, and keeps the record 200 in good condition.

[0034] Furthermore, according to the above embodiment, the protector 100 has an extremely simple structure and can be made of readily available materials, making it excellent both economically and in terms of productivity.

[0035] Furthermore, according to the embodiment described above, the protector 100 is lightweight, so that the load on the record 200 and turntable 410 and adverse effects on record playback can be significantly reduced.

[0036] It should be noted that the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the gist of the present invention. [Explanation of symbols]
