Description

[Brief explanation of the drawing]

Fig. 1 is a plan view showing an embodiment of the small tape cassette adapter according to the present invention with the top plate removed, and Fig. 2 shows an example of the small tape cassette housed in the adapter shown in Fig. 1. 3 shows the structure of the gear train of the drive system of the tape loading mechanism, sectional view taken along line I-I in FIG. 1, and FIG. 4 shows the reel. A cross-sectional view taken along line 1-1 in Fig. 1 showing the structure of the gear train of the drive system, Fig. 5 shows the locking mechanism of the lid that constitutes a part of the present invention, and Fig. A sectional view showing the state of the operation knob and related mechanisms when the cassette tape is stored, the lid is closed, and the tape loading operation is performed within the adapter.
6 is a sectional view showing the state of the operating knob and related mechanisms when the unloading operation is started by operating the operating knob from the state shown in FIG. 6. FIG. 6 is a sectional view of the connecting rod.
The figure is a circuit diagram showing the motor drive circuit inside the adapter.
A in the same figure shows a loading state, B in the same figure shows a state in which loading is completed, and C in the same figure shows a state in which unloading starts.

Claims (1)

[Scope of utility model registration request] A storage section that stores small tape cassettes that are smaller than the standard type, a lid section that covers the top of the small tape cassettes stored with the lid closed, and a lid section that moves in one direction to accommodate the front tape path of the standard type tape cassettes. a tape loading mechanism that performs a tape loading operation to form a corresponding tape path, and performs a tape unloading operation that operates in the opposite direction to store the tape forming the tape path in the small tape cassette; A small tape cassette adapter used in a magnetic recording and reproducing device for standard type tape cassettes, comprising: a motor unit that drives the tape loading mechanism; a power supply unit that supplies power to the motor unit; a first detection means for detecting a small tape cassette stored in the storage section; a second detection means for driving the tape loading mechanism according to opening/closing operations of the lid section; and operation of the loading mechanism. and a third detection means for detecting the state, and the drive circuit of the motor section is configured to operate according to the detection states of the first detection means, the second detection means, and the third detection means during tape rotation. 1. An adapter for a small tape cassette, wherein a drive circuit for a motor section is formed by the second detection means and the third detection means during tape unloading.
