【考案の詳細な説明】
この考案は、テープの弛み出しを防止するテー
プ押え片を備えたテープカートリツジに係り、テ
ープ押え片の固定手段に改良を加えたものであ
る。[Detailed Description of the Invention] This invention relates to a tape cartridge equipped with a tape holding piece that prevents the tape from coming loose, and is an improvement to the means for fixing the tape holding piece.
この種テープ押え片は弾性を有するプラスチツ
クシートからなり、上下ケースからなる本体ケー
スの下ケースに基端部が片持ち状に支持固定さ
れ、先端部がテープガイド部材にテープを挟んで
弾性接当することにより、テープが本体ケース前
面に弛み出ることを防止している。 This type of tape holding piece is made of an elastic plastic sheet, and the base end is supported and fixed in a cantilevered manner to the lower case of the main body case, which consists of an upper and lower case, and the tip end is elastically abutted to the tape guide member with the tape sandwiched between them. This prevents the tape from coming loose on the front of the main case.
テープ押え片を下ケース内に固定するについて
は下ケースの壁面に両面接着テープで接着固定す

めあるいは熱溶着などの固定手段に比較して下ケ
ース内の狭隘な箇所でも固定が容易な点で有利で
はある。 To fix the tape holding piece inside the lower case, a means of adhesively fixing it to the wall surface of the lower case with double-sided adhesive tape is adopted. This adhesive method is advantageous in that it can be easily fixed even in a narrow place within the lower case compared to fixing means such as screw fixing or heat welding.
しかし、テープカートリツジが小型化されるに

小なためにテープ押え片が接着後の弾性復元力に
よつて剥がれてしまう不具合を招いている。 However, as tape cartridges become smaller, space constraints within the lower case become increasingly severe, making it impossible to form a special wall surface for adhesively fixing the base end of the tape holding piece. It's becoming possible. For this reason, existing wall surfaces have a wide flat straight wall surface that is convenient for adhesive fixing, but have only a limited width, and because the adhesive area is too small, the tape retaining piece has no elastic restoring force after adhesive bonding. This causes problems such as it twisting and peeling off.
この考案は、係る事実に着目して、テープ押え
片の基端部を接着固定する下ケース側の壁面を高
くしてテープ押え片の接着面積を稼ぎ、これで接
着強度を高めることを第１の目的とする。 Focusing on this fact, this idea aims to increase the bonding area of the tape holding piece by increasing the adhesive area of the tape holding piece by raising the wall surface on the lower case side where the base end of the tape holding piece is adhesively fixed, and thereby increasing the adhesive strength. The purpose of
以下、その詳細を図面に基づき説明する。 The details will be explained below based on the drawings.

のを防止する構造になつている。 The drawing shows an example of a small video tape cartridge, the main body case 1 of which is made up of an upper case 1a and a lower case 1b made of plastic, which are divided into equal parts in the height direction, and are joined together with screws or the like in a manner that the lids fit together. Tape reels 2, 2 are rotatably installed inside the central portion on the left and right sides, and a tape 3 is wound between these tape reels 2, 2. Tape 3 is 2 each on the left and right
The tape is guided by tape guide members 4, 5, 6, and 7 made of loose plastic rollers, led out from one tape reel 2 to the outside of the front surface of the main case 1, and then wound onto the other tape reel 2. The main body case 1 is attached with a front cover 8 which can be opened and closed to cover the outside of the front surface of the main body case 1 and protect the tape 3 when not in use. A tape presser piece 10 is arranged between the tape guide members 4 and 5 on the left side of the lower case 1b and between the tape guide members 6 and 7 on the right side, respectively,
By bringing the presser piece 10 into elastic contact with the tape guide members 4 and 7 with the tape 3 in between, the tape 3 is prevented from coming loose toward the front side of the main case 1.

エチレン樹脂シートなどが貼着してある。 In FIGS. 2 to 4, the tape holding piece 10 on the left side is entirely made of a strong and elastic plastic sheet, such as a polyethylene resin sheet or a thin metal plate, and has an H-shape when viewed from the front. It is stamped and molded. Proximal end 10 of this
a is formed into a vertically elongated rectangular shape having a top and bottom width dimension that is approximately the same as the height dimension h of a side wall portion 11 of the lower case 1b, which will be described later, and a double-sided adhesive tape 12 is adhered to one side of the rectangular shape to form an inner surface of the side wall portion 11. It is fixed with adhesive. The distal end portion 10b, which is provided at a distance from the base end portion 10a by the narrow connecting portion 10c, is formed into a vertically long rectangular shape having a vertical width that is approximately the same as the height dimension of the tape guide member 4. It is sandwiched and elastically abuts on the tape guide member 4, and a slippery material 14, such as a tetrafluoroethylene resin sheet, is adhered to the joint portion with the tape 3.

を高める。 The side wall portion 11 to which the base end 10a of the tape holding piece 10 is adhesively fixed is connected to the left end of the tape reel movement regulating wall 15 disposed on the front side of the lower case 1b from a stepped bottom wall 16 continuous therewith. It is erected integrally, and its inner wall surface is formed into a flat vertical adhesive surface 17. Height dimension h of this side wall portion 11
is set as high as possible than the dividing line L between the upper and lower cases 1a and 1b, that is, the height dimension h1 of the surrounding wall 18 of the lower case 1b, and when the upper case 1a is superimposed on the lower case 1b, the side wall portion 11 is Upper surface 11a
is in direct contact with the inner surface of the upper wall of the upper case 1a. In a small tape cartridge, the side wall portion 11 cannot be thick enough to maintain strength with respect to this height dimension h, so the right end of the adhesive surface 17 of the side wall portion 11 is attached to the right end of the side wall portion 11, which is equal to the total height of the side wall portion 11. A reinforcing rib 19 having a height is integrally formed in the vertical direction, and the strength of the side wall portion 11 is increased by this reinforcing rib 19.

なる。 To adhere the tape holding piece 10 to the adhesive surface 17 of the corresponding side wall portion 11, the proximal edge 10d of the holding piece 10 is butted against the reinforcing rib 19, and the adhesive surface 1
7 with a double-sided adhesive tape 12.

い。 Note that a front wall 20 having the same height as the left end of the side wall portion 11 is obliquely integrally formed, and the height dimension of this front wall 20 is equal to the height dimension h 1 of the lower case surrounding wall 18. There is no problem in setting it the same as .

殊更に高くする必要はない。 The structures of the tape holding piece 10 on the left side and the side wall portion 11 to which it is adhesively fixed are as described above, and the structure on the right side is also substantially the same as that on the left side. However, in the case of the one on the right side, there is room to make the flat adhesive surface 17 convenient for adhering the tape holding piece 10 long on the left and right, so if the base end 10a of the tape holding piece 10 is made into a horizontally long rectangular shape. ,
It is not necessary that the side wall part 11 with the adhesive surface 17 be particularly higher than the dividing surface.
また、テープ押え片１０がテープ３をはさんで

対応できる利点を有する。 As explained above, according to this invention, the side wall portion 11 having a preferably flat and perpendicular bonding surface 17 is formed protruding higher than the dividing line L to increase the area of the bonding surface 17. Therefore, simply by setting the vertical width dimension of the base end 10a of the tape presser piece 10 to be approximately equal to the height dimension h of the adhesive surface 17, the base end 10a of the tape presser piece 10 can be firmly attached to the adhesive surface 17. Can be attached to. In addition, reinforcing ribs 19 are integrally formed on the adhesive surface 17 of the side wall portion 11 to prevent a decrease in rigidity due to an increase in the height dimension h. In addition, when assembling the tape retaining piece 10, by abutting the proximal edge 10d of the proximal end portion 10a against the reinforcing rib 19, it is possible to provide sufficient strength to prevent deformation. It also has the advantage of being able to be accurately positioned and easily assembled, improving assembly work efficiency, and particularly being able to respond well to downsizing of tape cartridges.
