JPS58114375A - Cassette adaptor - Google Patents

Abstract

PURPOSE:To ensure an effective protection of a magnetic tape, by providing a means that detects whether or not a magnetic tape is drawn out of a small- sized cassette stored in an adaptor, and at the same time, inhibits the shift of the cassette. CONSTITUTION:A small-sized cassette 7 is put into a cassette adaptor 13, and a loading lever 16 is moved toward an arrow 17. Then levers 18 and 19 turn centering on fulcrums 18a and 19a, and a magnetic tape 30 is guided by draw- out guides 14 and 15 and drawn out to a prescribed position. A lock lever 31 fixes the shift of the lever 16 at two areas. When the projected part 38 of the lever 16 gets out of the position of a groove part 39 of a cover 35, the load/ unload is locked. When the tape 30 is set back to its original position, a rack gear 45 turns a gear 42a. The sag of the tape 30 is eliminated by a reel 11a and via idlers 42, 40 and 41. Meanwhile the shift of the cassette 7 is locked to protect the tape 30.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to @Fis cartridge adapters, and particularly relates to a power command adapter for small-sized 1111 sets that allows use of small-sized cassettes in playback devices.

In this type of cassette adapter, the recording medium is located at a position k within a large ffl force.

It is necessary to pull out the recording medium from the small cassette and place it inside the adapter. Shikaji recording medium is l from Kojiji cassette! In view of the above points, the present invention has been developed in view of the above points, since the recording medium is small. A cassette adapter is provided in which the small cassette is fixed to the adapter and cannot be removed when it is pulled out of the IIi cassette.

As an example of this woodcutter's cassette adder, magnetic*ii
The following describes an adapter for use with i-replay (referred to as replay VTR). 1II is a diagram showing an example of a large cassette. 1 is Kasetsu) Reels 2 and 3 in half
is provided. 4.5 is a tape guide. A reel 2.3KFi magnetic tape 6 is wound and loaded. FIG. 2 is a diagram showing an example of a small cassette. 7 is provided with Osset hard 7 and low #10.11, and 8
, 8'.

9 and 9' are tape guides, and 12 is a magnetic tape.

FIG. 5 is a diagram showing the quick operation of the cassette adapter of the present invention. Reference numeral 013 is the main body of the cassette adapter. When inserting the small cassette 7 into the adapter, pull out guide 14.
15 is the fifth. In H, they are located at the positions indicated by M and IB, respectively. When the loading lever 16 is moved in the direction shown by the arrow 17, the lever 18.1? which interlocks the drawer guide 14.15? 20° rotate in the direction of arrow 210 about the fulcrums 1g & 191L, respectively. Reference numerals 22 and 23 are control bins for controlling the rotation of the levers 18 and 19, and are provided on the levers 18 and 19. Numerals 24 and 25 are nine long grooves provided in the loader lever 16 into which the control pins 22 and 25 are fitted. Similarly, the long groove part 28,
29 is also provided on the Dindareper 16. As a result, the magnetic tape 30 is pulled out to a predetermined position when a large ffi cassette is used. 31 is Rodin-

Before the magnetic tape 30 is pulled out, the low-disc fern detection protrusion 113B that has been removed is at the position KTo of 8859 of 7-35.

◎If Nasukechi 130 is pulled out even a little, @5mK shows, Oki 11138 and #Ii$3
Since the position of 9 is shifted and the 7th voice 35#i is fixed, the small Il'jI dragonit 7 cannot be inserted or removed.

Further, when the wrinkle cassette 7 in the cassette adapter is inserted and the VTR 99 is operated as described above, the idler 40 is driven. When the idler 40 is driven, the idler 41 interlocked with it is also driven, and the reel 11& is rotated. Hereafter, when unloading/undertaking, that is, when pulling 11a1 and returning F14, 15 to the original position of person B. Take Liu's action 0 first 1
- When the derailleur 16 is moved in the direction of the arrow 17', the levers 18 and 19 are moved in the directions of the arrows 20' and 21', respectively, contrary to when the magnetic tape 5G is pulled by 1 m.

Return to position B0 At this time, the reel I1m must be turned over so that the magnetic tape 160 does not become sluggish due to surplus.0 Figure 5 is a diagram showing the details of the magnetic tape winding mechanism. 0 Loading Dale Per 16 is arrow 1°
When moving in the direction of 7', -1 of Dindarepā 16
1Kjl is attached to the footer gear 45IIi85, which moves in the direction of the arrow 46 as shown in FIG. Then, a nine gear 42 is provided on another idler 42 that is interlocked with the idler 40.
The steel wheels of m engage each other and rotate the idler 42. As a result, idler 40. The idler 41 makes a complete turn, and eventually becomes low, and the idler 11a makes a complete turn in the direction of winding the magnetic tape 50. Gear 421L
#) - Magnetic tape 30 is enough to wind the rotation number! It is set so that it can be taken. However, in order to avoid excessive winding, the rack gear separates from the gear 42 against the force of the elastic body 14 shown in 5- during the running time when the magnetic tape 3 is OK and the rack gear is separated from the gear 42. 45 is a rack gear 450--When the magnetic tee 130 is pulled out at the zero cross point which is the fulcrum, the rattling gear T45 and the gear 42a slip and do not engage, so the minimum amount of the magnetic tape 13 is pulled out by the pulling guide 14 and 15. Since the magnetic cable 1 is only loose, it has a structure that does not look like a nematode. 1'jI set to the adapter (When entering the town, detect the position of the magnetic tape to be pulled out @And when the magnetic tape is not pulled out (@), the small Ii! I'j 1 set of gin is inserted The magnetic tape may become loose, or if it is exposed from the small wire and in good condition, it may not be able to be set easily, and the magnetic tape may become wound due to the position 11111 of the pull-out position. Since he was no longer left with loose hints, he used a trowel to roll the magnetic tape.

Umbrella recesses 471 and 47b are provided as shown in Fig. 6, which is a diagram showing an example of the ring of the cassette adapter of Shamoto Yumei.
The convex s49 of the control lever 48 is fixed to a concave ms 47a K when the magnetic tape is being pulled out, and to a concave 1147111 K when the magnetic tape is not being pulled out. Figure 7 is a Confucian garden showing the control mechanism of Reko. Figure 7 Hirotsu It! 49 is fixed to the adapter body, and the control lever <-48 is energized by the screw 51 attached to the adapter body. This causes a part of the control lever (-48 50 is pressed by the opening/closing button 65, and the opening/closing plume 65 is kept constant.
49 is l this time! 1 Iku 47bKlilil is determined. Then, the control lever (-48) moves in the direction of the arrow 52 in Fig. 7, and the opening/closing button 65 becomes rotatable around the fulcrum 66, allowing the 5-point proof Rikiryutsuto 7 to be taken in and out. The configuration shown in FIG. 6 can also provide the same effect as the configuration shown in gsaii.

Furthermore, in the embodiments shown in FIGS. 5 and 6, the detection of whether or not the magnetic tape is being pulled out is performed mechanically; however, it can also be detected electrically.
When the motor is installed in the main body 16 as a driving source for the loading lever 16, a detection protrusion is provided on the loading lever 16, and the position of the detection protrusion is detected using photocapfu. 0 and the locking means is electrically coupled to the sensing means. Electrical detection is also possible in the above manner.As explained above, according to the present invention, when the recording medium is removed from the cassette, a small m cassette cannot be inserted into or removed from the adapter. It is very effective in preserving the recording medium.
