産業上の利用分野
本発明は録音あるいは録画等に用いるテープカセットに
関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tape cassette used for recording or recording.
従来例の構成とその問題点
従来、テープカセットは第１図、第２図に示すように、
重ね合わせた上ハーフケース１と下ハーフケース２との
間にテープ（図示せず）を収納し、そして両ハーフケー
ス１，２内にそれぞれ対向して一体に突出形成した複数

あった。しかしながらこのねじ結合を行なうもめでは、
ねじの締付は後にもう一度締付けを行なって確実に締伺
けが行なわれているかどうかその締付は負荷の上昇によ

このためボス３．４の圧接面が変形したシ、残留応力に
よってハーフケースに反りや変形が生じ、組立て後の寸
法精度が失なわれてしまうという不具合があった。Conventional structure and its problems Traditionally, tape cassettes were as shown in Figures 1 and 2.
A tape (not shown) is stored between the stacked upper half case 1 and lower half case 2, and a plurality of bosses 3.4 are integrally formed to face each other and protrude inside both half cases 1 and 2, respectively. A screw 6 is screwed into the top half case 1 from the upper half case 1 side, and both half cases 1.2 are tightened and fixed. However, in this struggle to make a screw connection,
Screws are tightened again afterward, and the tightening is detected by the increase in load to ensure that it has been tightened, so the tightening due to inertia after this detection is also increased. If a force greater than necessary is applied,
As a result, the pressing surface of the boss 3.4 was deformed, and the half case was warped or deformed due to residual stress, resulting in a loss of dimensional accuracy after assembly.
また、一部においてねじを用いずに、テーパピンを圧入

めノ・−フケースに反りや変形を生じさせ、また圧入保
持が不充分なものであったりして広く実用されるに至っ
ていないものであった。In addition, some proposals have been made in which a taper pin is press-fitted without using screws, and in which the tip of the pin is made thicker to prevent it from coming out, and the two half cases are joined together. Since the depth of press-in of the pin is not regulated, the no-f case may warp or deform, and the press-fit retention is insufficient, so that it has not been widely put into practical use.
発明の目的

本発明は簡単な構成で精度よく組立てることができるテ
ープカセットを提供するものである。OBJECTS OF THE INVENTION (1) The present invention provides a tape cassette that has a simple structure and can be assembled with high precision.
発明の構成
本発明は両ハーフケースを複数のストレートピンとスト
レート孔との圧入嵌合で結合し、かつその嵌合長さをス
トレートピンの直径の１．６倍以上としたものであり、
これにより複数の嵌合部を同時に抜かない限り両ハーフ

。Structure of the Invention The present invention combines both half cases by press-fitting a plurality of straight pins and a straight hole, and the length of the fitting is 1.6 times or more the diameter of the straight pin,
This makes it impossible to separate both half cases unless a plurality of fitting parts are pulled out at the same time, thereby ensuring press-fitting and maintaining good assembly accuracy.
実施例の説明
以下本発明の一実施例について第３図〜第６図を用いて
説明する。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 to 6.
６は上ハースケース、７は下ハーフケース、８および９
は前記両ハーフケース６．７の対向する複数個所の内面
部に一体に形成されたボス、１０は前記上ハーフケース

る。6 is the upper hearth case, 7 is the lower half case, 8 and 9
10 is a straight pin integrally formed on each boss 8 of the upper half case 6;
Reference numeral 11 denotes a straight hole into which the straight pin 1o formed at each boss 9 portion of the lower half case 7 can be press-fitted.
第４図は前記ストレートピン１ｏ部の側面図で、そのス

されている。また、第５図はストレート孔１１部の断面
図で、ボス９の開口端部には前記ストレートピン１０の
テーパ径大部１０ａが嵌合するテーパ開口部１１ａが形
成されている。FIG. 4 is a side view of the straight pin 1o, in which a tapered large-diameter portion 10a is formed at the base of the straight pin 10 for reinforcing and positioning purposes, and the diameter increases toward the boss 8. A tapered portion (10b) is formed. FIG. 5 is a cross-sectional view of the straight hole 11, and the open end of the boss 9 is formed with a tapered opening 11a into which the large-diameter tapered portion 10a of the straight pin 10 is fitted.
なお、上記ストレートピン１０とストレート孔１１によ
る実質的な嵌合長さはそのストレートピン１０の直径の
１．６倍以上に設定されている。Note that the substantial length of the fitting between the straight pin 10 and the straight hole 11 is set to be 1.6 times or more the diameter of the straight pin 10.
以上のような構成からなり、上ノー−７ケース６と下ハ
ーフケース７はその上ノ１−フケース６の各ストレート
ピン１ｏを下ノ１−フケ−スフの各ストレート孔１１に
対応させてそのピン１０を孔１１内に圧入嵌合させる。With the above structure, the upper case 6 and the lower half case 7 are arranged so that each straight pin 1o of the upper case 6 corresponds to each straight hole 11 of the lower case 6. The pin 10 is press-fitted into the hole 11.
すると各ピン１ｏのテーノ（径大部１０ａが孔１１のテ
ーノく開口部１１ａに嵌合されるため両）・−７ケース
６．７は相互に確実に位置決めされる。Then, the large-diameter portion 10a of each pin 1o is fitted into the large-diameter opening 11a of the hole 11, and the -7 cases 6.7 are reliably positioned relative to each other.
前記各ストレートピン１０がストレート孔１１に圧入嵌

ケース６．７が高精度を保ちながら平行に引き離されな
い限りその両ノ・−フケース６，７はストレートピン１
ｏとストレート孔１１の圧入嵌合による保持力によって
結合され、両者は一体となる。When each of the straight pins 10 is press-fitted into the straight hole 11, the press-fitted length is 1.6 times or more the diameter of the straight pin 1o, so both half cases 6.7 are high. Unless they are pulled apart parallel to each other while maintaining accuracy, the two nozzle cases 6 and 7 will be straight pins 1.
o and the straight hole 11 are connected by the holding force generated by press-fitting, and the two become integral.

立て状態が得られるものである。Therefore, by press-fitting the plurality of straight pins 10 and the plurality of straight holes 11, the force applied to the bosses 8.9 is small, and there is no possibility of deformation or destruction. The mutual positions of the half cases 6 and 7 are maintained with high precision by the engagement of the tapered large-diameter portion 10a and the tapered opening 11b.
．． 7 is not distorted or warped, and a highly accurate assembled state can be obtained.

そのノ・−フケースの外壁の内面等で行なってもよい。FIG. 6 shows another embodiment, in which a notch step 1 is formed around the straight pin 10 of the upper half case 6 at the inner edge of the L end.
2a is integrally formed, and a cutout stepped portion 9a is formed at the outer edge of the tip of the boss 9 of the lower half case 7, and both of the cutout portions 12a and 9a fit into each other. By this, the two half cases 6 and 7 are positioned relative to each other, and the same effect can be achieved even if the two half cases 6 and 7 are formed into a rectangular shape as shown in FIG. . Further, the mutual positioning of both half cases may be performed by the inner surface of the outer wall of the half case.
なお、ストレートピン１ｏとストレート子し１１は成型
時に必要なテーパを有していてもよい。Note that the straight pin 1o and the straight piece 11 may have a taper necessary for molding.
発明の効果

従来のねじを用いるものに比べて結合作業が簡単である
のみならず、締付は力が加わらないためハーフケースに
歪が発生したり、反りが生じたりするようなことがなく
、高精度な組立て状態が得られるものである。Effects of the Invention In the present invention, as described above, both half cases are connected by press-fitting a straight pin and a straight hole.
Not only is the connection work easier than with conventional screws, but since no force is applied during tightening, there is no distortion or warping of the half case, and high precision is achieved. An assembled state can be obtained.
