Abstract

PURPOSE:To decrease the number of component parts and to improve the operability with a cassette tape recorder by locking and releasing a subcase in response to an opening/closing action of the 2nd housing. CONSTITUTION:When an open button 7 is slided toward an arrow head A and a lock part 7a is unlocked from an engagement part 6d of a mechanism substrate 6, an engagement part 2f of the 2nd housing 2 is detached from a projected part 1a of the 1st housing 1. Then the housing 2 is turned by a subcase open spring 13, and a hook part 10c of a lock plate 10 engages an engagement part 16b of a coupling plate 16. Under such conditions, a cassette tape 19 is inserted from the side of an arrow head B and the housing 2 is closed toward an arrow head C. Then a shaft 17 of a toggle plate 14 moves toward an arrow head D, and the plate 10 also moves along a groove part 6c of the substrate 6 by means of the plate 16. When the tape 19 is loaded, the force is applied to the housing 2 from the side of an arrow head E by a toggle spring 18. Thus the tape 19 is held. Then the case 9 is locked by the plate 10 and is never turned.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette tape recorder, and more particularly to a cassette storage device.

Conventional Structures and Their Problems As cassette tape recorders have been made smaller and thinner, contradictory problems have arisen in that operations such as loading and unloading cassettes become difficult to use.

OBJECTS OF THE INVENTION The present invention solves the problems described in ``2'' and simplifies the operation and enables easy and reliable operation.

Structure of the Invention The present invention includes a first casing having a drive mechanism for a tape recorder, and a car 1. e) A second housing for holding the cassette tape, which is configured to protrude from the first housing in the direction of the short side of the cassette tape and be overlapped when the tape is attached, and the first housing and the second housing. It is rotatable relative to each of the cassette tapes, and when a cassette tape is not installed, it is housed on the top surface of the first casing within the second casing, and when a cassette tape is installed, the lower part of the second casing serves as an exterior case device. Since the sub case is separated from the sub case and the rotation of the sub case is locked with respect to the first case by opening and closing the second case, it is not necessary to perform other locking and unlocking operations. This allows easy operation.

DESCRIPTION OF EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 1 to 9. FIG. 1 is a perspective view when the cassette tape is not installed, FIG. 2 is a perspective view when the second casing is opened, and FIG. 3 is a perspective view when the cassette tape is installed.

FIG. 4 is an exploded perspective view of the main parts, and explains the rotation of the second casing and the structure of the locking device. 2 is a second housing that holds the force/set tape, 2a is a hole that slides through the lock portion 7a of the open button 7, and 2b is a hole that engages with the hook portion 7b of the open button 7. , 2c is a guide portion that guides the open button spring 8, and the open button 7 is biased by the open button spring 8 in the direction indicated by the arrow. 2d is a hole 9a of the sub case 9 and a long hole 10a of the lock plate 10.
This is the center of rotation of the second casing 20 that allows the shaft 11 to pass through. The subcase 9 is rotatably supported on the mechanism board 6 by a shaft 12 through a hole 9b, a subcase open spring 13, a hole 6a of the mechanism board 9, and a long hole 1ob of the lock plate 10. The open spring 13 is biased in the opening direction. The lock plate 10 is configured to be slidable with respect to the subcase 9. Reference numeral 2e denotes a toggle holding portion, into which the shaft 15 is inserted through the hole 14a of the toggle plate 14. The toggle plate 14 which has been torn off is fitted with a shaft 17 so as to be slidable through the hole 14b, the elongated hole eb of the mechanism board 6, and the hole 16a of the connecting plate 16. The hooking of the toggle barb 18 between the shaft 17 and the mechanism board 6 urges the toggle plate 14 in the direction of arrow B. 16b of the connecting plate 16 is a retaining part that engages with the hook part 10c of the lock plate 10. 2f of the second housing 2 is a retaining portion that engages with the convex portion 1a of the first flute body 1. 6e of mechanism board 6
A mechanism board 6 is attached to the first casing 1.

Next, the operation will be explained with reference to FIGS. 6 to 8. 6th
The figure is a side view when the cassette tape is not installed, and when the open button 7 is slid in the direction of the arrow as shown in FIG. 6 and the lock part 7a is removed from the engaging part 6d of the mechanism board 6, as shown in FIG. 7. , the retaining portion 2f of the second casing 2 separates from the convex portion 1a of the first casing 1, and the second casing 2 begins to rotate by the sub-case open spring 13 as shown in FIG. The hook portion 10c of the lock plate 10 engages with the engaging portion 16b of the connecting plate 16. In this state, cassette tape 19
is inserted from the direction of arrow B, and when the second housing 2 is closed in the direction of arrow C, the shaft 17 of the toggle plate 14 moves in the direction of the arrow, and the lock plate 1o is also moved along the groove 6C of the mechanism board 6 by the connecting plate 16. When the cassette tape 19 is held by the toggle spring 18 and the cassette tape 19 is held, the sub case 9 is prevented from rotating by the lock plate 1o. locked. By closing the second casing 2 as described above, the rotation of the sub-case 9 is locked, making it possible to hold it easily and reliably.

Effects of the Invention As products become smaller and thinner, locking mechanisms such as rotating parts become very difficult due to space limitations, and additional operations such as unlocking are required, making it less convenient to use.
According to the present invention, the subcase can be locked and unlocked by performing the related operations of opening and closing the second casing, and the effects such as reducing the number of components and improving the operational surface are significant.
