Abstract

A tape release prevention guide of a tape recorder is disclosed. The disclosed tape release prevention guide is formed by protruding the guide portion to the existing head drum cover without making and installing a separate tape release prevention guide, and the guide portion of one pair of pole bases and the capstan motor shaft and When the magnetic tape of the section compressed by the pinch roller is relaxed by the operation mode conversion or the like, and thus is departed from the normal driving path, the magnetic tape may be prevented from interfering with the upper end of the magnetic tape.

Description

Tape release guide for tape recorders

The present invention relates to a tape guide of a tape recorder, and more particularly, to a tape release prevention guide for preventing magnetic tape from escaping a normal driving path around a head drum during a mode conversion of a camera-integrated tape recorder.

Tape recorders for recording / reproducing information by scanning magnetic heads on magnetic tapes, such as VTRs, draw the magnetic tape from a tape cassette loaded with a series of drive mechanisms mounted on the deck and rotate the head. The vehicle is driven while being loaded to be wound about half a turn on the outer circumferential surface of the drum. The magnetic tape traveling in this way is conveyed along the tape traveling system in a state of being guided by a tape guide roller such as a pole base, a review arm, or the like. By the way, in the case of a compact camera-integrated video tape recorder called a camcorder, a photographer often takes a picture while inverting the body of the tape recorder in various forms, for example, by laying down and shooting. In this case, since the deck of the tape recorder does not maintain the horizontal state, in particular, the magnetic tape wound around the outer circumferential surface of the head drum is loosened when the operation mode is changed, which often causes a deviation from the normal driving path. As such, the head drum cover 200 as shown in FIG. 1 is employed in the conventional tape recorder to prevent the magnetic tape from deviating from the normal driving path. The head drum cover 200 is a mold manufactured by a conventional injection molding, and a rotating head drum installed on the deck main base (not shown) of the tape recorder by the drum base 110 as shown in FIG. It is supported by the main base so that it can be located above the 100.

However, the conventional head drum cover 200 can prevent the magnetic tape from escaping to the upper portion of the head drum 100, but as shown in FIG. 3, the magnetic tape 10 is pulled out to rotate the head. Magnetic tape 10 in a section that is compressed by one pole base 120, the capstan motor shaft 130 and the pinch roller 140 of the pair of pole bases to be loaded about half a turn on the outer peripheral surface of the drum 100 Since there is no guide means for guiding), when the magnetic tape is easily deviated from the normal driving path as indicated by reference numeral 10 'when the operation mode is changed, for example, the head is recorded while inverting the body of the tape recorder in various forms. There is a problem that the magnetic tape is separated to the top of the drum.

Accordingly, the technical problem to be achieved by the present invention is to solve the conventional problems as described above, the present invention is a tape that can completely prevent the magnetic tape from deviating from the normal driving path when the tape recorder is inverted or the operation mode is changed. The purpose is to provide a departure prevention guide.

In order to achieve the above object, the tape release prevention guide of the tape recorder according to the present invention includes a cover member installed around the cover member so as to cover an upper portion of the head drum rotatably installed on the deck main base of the tape recorder, and the cover member. On the outer circumference of the head drum is characterized in that the one side pole base for loading the magnetic tape to be wound about half a turn and the guide portion protruding to be located at the upper end of the magnetic tape in the section between the capstan motor shaft and the pinch roller do.

Hereinafter, with reference to the accompanying drawings will be described in detail the tape release prevention guide of the present invention according to a preferred embodiment.

4 is a schematic plan view showing the main part of the tape recorder to explain the tape release prevention guide of the tape recorder according to the present invention, and FIG. 5 is a view illustrating the operation of the tape release prevention guide according to the present invention of FIG. Schematic perspective view. 4 and 5, the tape release prevention guide of the tape recorder according to the present invention is installed on the top of the rotating head drum 100 installed on the deck main base (not shown) of the tape recorder by the drum base 110. A head drum cover 300 made of a mold by a conventional injection molding supported on the main base and a magnetic tape may be pulled out and wound about half a turn on the outer circumferential surface of the rotating head drum 100 so as to be positioned. The head drum cover 300 to be located at the upper end of the magnetic tape 10 in the section of the pair of pole bases to be loaded by one side of the pole base 120, the capstan motor shaft 130 and the pinch roller 140 It comprises a guide portion 310 protruding to one side of the).

The guide unit 310 is taken while inverting the body of the tape recorder in various forms or when switching the operation mode, as shown in FIG. 5, one pole pole 120 of the pair of pole bases and the capstan motor shaft 130 and When the magnetic tape 10 of the section compressed by the pinch roller 140 is relaxed to leave the normal driving path, the magnetic tape 10 is prevented from interfering with the upper end of the magnetic tape 10 to the upper portion of the head drum.

As described above, the tape release prevention guide of the tape recorder according to the present invention is formed by protruding the guide portion to the existing head drum cover without producing and installing a separate tape release prevention guide so that the tape is around the head drum. It is possible to completely prevent the departure from the normal driving path.

Claims (1)
