Description

[Technical Field]

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

[0002] In recent years, analog records have become increasingly popular. The main material used to make records is polyvinyl chloride, which tends to become negatively charged, making it easy for dust and dirt to adhere to it. Therefore, in order to keep records in good condition, it is recommended that you clean them regularly.

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

[0004] Patent Document 1 discloses a record cleaning tool that covers the label area formed in the center of a record, and is equipped with a set of cover members that cover the label area from both sides 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 periphery and have a through hole in their center that coincides with the center hole of the record, and the male screw member is inserted through the center hole of the record and the cover members at a position where the center hole of the record and the through hole of the cover members are aligned, and the female screw member is screwed into the cover members, thereby clamping the record between the set of cover members.

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

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-30711 [Non-patent literature]

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

[0008] As mentioned above, record center labels often have unique designs. For records to be highly valued 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 player plays a record by lowering a needle onto a rotating record on a turntable. Generally, the needle moves from the outside to the inside of the record as it rotates. When the needle reaches the innermost groove of the record, depending on the condition of the record player, needle, or record, it may penetrate into the center label and damage it.

[0010] The devices disclosed in Patent Document 1 and Non-Patent Document 1 are intended to remove dust and dirt that has accumulated in 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 washed 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 its object is 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.

[0013] (1) A protector for the center label of a record, made of resin or rubber, removably attached to the record so as to cover the top surface of the center label, with a thickness of 0.5 mm to 1.5 mm and an area of ​​the top surface equal to or greater than the area of ​​the top surface of the center label.

[0014] (2) A protector for a record center label according to (1) above, which is circular in plan view and has a hole in the center.

[0015] (3) A method for protecting the center label of a record, comprising: attaching a protector for the center label of a record made of resin or rubber, having a thickness of 0.5 mm to 1.5 mm, an area of ​​its top surface equal to or greater than the area of ​​the top surface of the center label, and having a circular shape in a planar view, to the record so as to cover the top surface of the center label; and when the record is played on a record player, the protector for the center label of the record prevents contact between the record needle installed on the record player and the center label. [Effects of the Invention]

[0016] The present invention can prevent damage to the center label caused by the record needle when playing back a record. [Brief explanation of the drawings]

[0018] Hereinafter, one embodiment of the present invention will be described with reference to the drawings. The protector 100 for record center labels according to this embodiment (hereinafter referred to as "protector") 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 desirable that the protector 100 be in close contact with a portion 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, and the like, and thermoplastic elastomers are suitably used. Furthermore, the rubber may be natural rubber or synthetic rubber, with soft rubber being preferred. 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. Furthermore, the protector 100 is preferably transparent or translucent, but may also be opaque.

[0020] The thickness (PT) of the protector 100 is 0.5 mm to 1.5 mm. Furthermore, 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). Furthermore, it is 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 periphery (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] A hole 110 is provided in the center 100b of the protector 100 to allow the protector 100 to be inserted detachably onto a center spindle 420 that protrudes from the center 400a of the 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 also includes the area corresponding to the space portion on the inner periphery side of the hole portion 110.

[0022] The record 200 has a groove 210. 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 the turntable 410. A paper center label 300 is attached or pressed into the central region 200a of the record 200. A hole 320 is formed in the center 300b of the center label 300, through which a center spindle 420 can be inserted and removed. The hole 320 is circular in 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 are such that the diameter (Φ1) is less than or equal to the 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 the range that allows the protector 100 to be inserted onto the center spindle 420 when setting the record 200 in the record player 400, and allows the protector 100 to 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 intended for 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 a cartridge 440 attached to a tip thereof 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 stylus 430 picks up sound signals from the 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 overlaps with the center hole 220 of the record 200 (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 over the record 200, and the stylus 430 is lowered into the desired groove 210 of the record 200, and playback of the record begins (step S630).

[0031] 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 record playback (step S640).

[0032] Normally, the stylus does not move further inward than the innermost periphery of the record. However, depending on the condition of the record player, the stylus, or the record, the stylus may move further inward than the innermost periphery of the record, i.e., all the way to the center label. Even in such a case, if the record 200 has the protector 100 attached, the stylus 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 stylus 430, preventing the stylus 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 the record 200 back into its jacket, the protector 100 can be removed from the record 200. In this embodiment, the protector 100 is made of soft polyvinyl chloride. This allows the protector 100 to be easily removed from the record 200 without damaging the record 200.

[0033] In this way, the protector 100 of this embodiment, simply by being attached to the top surface 300a of the center label 300, can prevent the stylus 240 from entering the center label 300 or coming into contact with the outer periphery 300c of the center label 300. This allows the protector 100 to prevent damage to the center label 300 and maintain 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 above embodiment, the protector 100 is lightweight, so that the load on the record 200 and turntable 410 and adverse effects on the playback of the record 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]
