る。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for assembling a tape cassette, which allows the tape cassette to be assembled with high precision.
従来例の構成とその問題点
従来、テープカセツトは第１図、第２図に示す

つた。Conventional Structure and Problems Conventionally, a tape cassette stores a tape (not shown) between an overlapping upper half case 1 and lower half case 2, as shown in FIGS. 1 and 2. Then, the upper and lower half cases 1 and 2 are tightened and fixed by screwing screws 5 from the upper half case 1 side into a pair of protruding bosses 3 and 4 formed in opposite directions in both half cases 1 and 2, respectively. It was something that existed.
しかしながら、この場合上ハーフケース１と下
ハーフケース２の平行度は主としてそれぞれのボ
ス３，４の対接面によつて決定され、したがつて
このボス３，４の対接面が傾斜していたり、複数

ツトが安定して装着されず、このためテープの走
行性能が著しく悪化するという問題があつた。 However, in this case, the parallelism of the upper half case 1 and the lower half case 2 is mainly determined by the contact surfaces of the bosses 3 and 4, and therefore the contact surfaces of the bosses 3 and 4 are inclined. If the tightening force of some of the screws 5 is too strong, the contact surfaces of the bosses 3 and 4 may be deformed, and the main planes of the half cases 1 and 2 will not be kept parallel.
When this tape cassette is installed in a tape recorder or the like, the tape cassette cannot be installed stably, resulting in a problem in that the running performance of the tape is significantly deteriorated.

溝１４ｂが形成されている。 10 is an upper half case, and 11 is a lower half case. A plurality of tapered pins 12 are integrally formed on the inner surface of the upper half case 10, and a tape guide pin 13 is formed on the inner surface of the lower half case 11. and a fitting boss 1 into which the pin 12 fits.
4 are each formed integrally. As shown in FIG. 4, the fitting recess 14a of the fitting boss 14 is formed in a tapered shape that becomes smaller in diameter toward the base of the fitting boss 14, and a plurality of grooves 14b are formed around the circumference. ing.

ている。 Reference numerals 15 and 16 denote plane plates that hold and regulate the main planes 10a and 11a of the upper half case 10 and the lower half case 11 in parallel with each other, and a plurality of pins 17 integrally protrude downward from the upper plane plate 15.
is brought into contact with the lower flat plate 16, thereby regulating the parallelism and spacing between the two flat plates 15 and 16, and the spacing is set to be the same as the thickness of the tape cassette.
つぎに、組立てについて説明すると、まず、上

ね合わせ、この状態で上方の平面板１５を上ハー
フケース１０の上方から押下げ、ピン１７を平面
板１６上に当接させる。 Next, to explain the assembly, first, adhesive is applied to the pin 12 of the upper half case 10 or the fitting recess 14a of the fitting boss 14 of the lower half case 11, and the lower half case 11 is attached to the lower flat plate. 16. Then, stack the upper half case 10 from above the lower half case 11 with its pin 12 shallowly fitted into the fitting recess 14a, and in this state push the upper flat plate 15 from above the upper half case 10. The pin 17 is brought into contact with the flat plate 16.
この場合ピン１２と嵌合凹部１４ａは適度の弾

ス１０，１１はピン１２と嵌合ボス１４との接着
により一体に結合される。 In this case, the pin 12 and the fitting recess 14a are formed to fit together with appropriate elasticity and have an appropriate resistance force against pressing down of the flat plate 15, so that both half cases 10 , 11 are in close contact with the flat plates 15, 16 to ensure their parallelism, and both half cases 10, 11 are integrally joined by adhesion between the pin 12 and the fitting boss 14. .
なお、前記両ハーフケース１０，１１の結合に
際して内部にテープが収納されることは当然であ
る。 Incidentally, it is a matter of course that a tape is housed inside when the two half cases 10 and 11 are combined.
以上のような組立て方法によれば両ハーフケー

The fitting with 1 is not limited to that of the above-mentioned embodiment. For example, the fitting boss 14 can be fitted with 2 as shown in FIG.
It may be formed by two parallel plate-like bodies, or the sixth
For example, as shown in Fig. 7, the lower half case 1
A projecting piece 18 that projects upward is formed on the inner surface of the side wall of the upper half case 10, and when the upper half cases 10 are overlapped, this projecting piece 18 engages with the inner surface of the side wall of the upper half case 10. Inject adhesive through the notch 19 formed in the side wall and attach both half cases 1.
0 and 11 may be connected by the protruding piece 18, and in this case, the adhesive may be applied to the protruding piece 18 in advance.
