Abstract

PURPOSE:To concretely recognize a magnetic tape amount to be remained in a supply side hub for a user by providing a meter part to be equipped with an arm part, which contacts with pressure to a tape to be wound to the two hubs, and a pointer which executes reciprocating motion on a scale to be fitted to the arm part. CONSTITUTION:An inside surface 13 of a brake arm 130, which is provided in a cassette tape main body 100, contacts with pressure to a magnetic tape 101 which is wound to hubs 108a and 108b. A meter pointer 131 is provided in the brake arm 130 and in correspondence to the coiling quantity of the magnetic tape 101 to the coiling side hub 108b of a recorder, the meter pointer 131 executes the reciprocating motion on a scale 136 which is provided on a transparent resin-made sheet 109. Then, the coiling quantity of the magnetic tape 101 to the coiling side hub 108b can be grasped with the concrete numerical value of the scale 136 through the meter window of a reinforcement panel part. Thus, the user can concretely recognize the tape remaining amount of the supply side hub 108a.

Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a cassette tape, particularly a tape used by a user. [Prior Art] A cassette tape 50 for recording and playback is generally used. As shown in FIG. 9, the cassette halves 51, 51 are formed entirely in a box shape and are made of thermoplastic resin. A supply side hub 52 and a winding side hub 53 rotatably supported within the cassette halves 51, 51, and these hubs 5.
2.53 and a magnetic tape 54 wound around the magnetic tape 54. In addition, in such a cassette tape 50, the supply side hub 52 and the winding side hub 53 of the cassette half 51 are
A transparent or translucent small window 57 for checking the remaining amount of tape is provided between the cassette half 51 and the cassette half 51. A scale 56 having a graduation is also widely used. [Problems to be Solved by the Invention] By the way, when performing recording work using such a conventional cassette tape 50, if the cassette tape 50 has already been recorded for a certain period of time, In this case, it becomes necessary to judge whether an unrecorded tape is sufficient for the next recording. In such a case, conventionally, a small window 57 provided in the cassette/\-f 51 for checking the remaining amount of tape is used. The amount of magnetic tape 54 remaining in the supply hub 52;
The amount of magnetic tape 54 wound on the take-up hub 53 must be compared using the scale 56 to determine whether the unrecorded tape remaining on the supply hub 52 is sufficient for the recording time. It was extremely complicated. Furthermore, some conventionally used cassette tapes do not have the scale 56 described above, and when using such cassette tapes,
In many cases, it was not possible to quickly determine whether or not the amount of magnetic tape 54 remaining in the supply hub 52 was sufficient for the required recording time. Furthermore, when playing back a cassette tape 50 that has already been recorded, the amount of tape remaining in the supply hub 52 is
It would be convenient if we could know more specifically from time to time. Therefore, a technical problem of the present invention is to make the user specifically aware of the amount of tape remaining in the supply hub. [Technical means for solving the problem] In order to solve such a technical problem, the present invention provides the following. A cassette tape comprising a cassette half, a supply hub and a take-up hub rotatably supported within the cassette half, and a tape wound around these hubs,
A meter section is provided, which includes an arm section that presses against both tapes wrapped around the two hubs, and a pointer that is attached to the arm section and moves back and forth on the scale. The present invention is characterized in that the magnetic tape field is formed so that the user can recognize it using specific numerical values at any time.

A reinforced panel part 110 made of stainless steel with high magnetic permeability and conductivity is placed below -E of the base part 102 in which the air tape 101 is installed.
, 110 are attached, even if there is an object that generates strong magnetism, such as a magnet, near the cassette tape main body 100, the magnetic flux from the object is highly permeable. Stainless steel reinforcement panel 110.
110, the magnetic influence on the magnetic tape 101 can be minimized. Furthermore, even if static electricity is generated due to friction between the magnetic tape 101 and the half due to high-speed running of the magnetic tape 101 during operation of the recorder/player, the reinforcing panel parts 110 and 110 are made of highly conductive stainless steel. Therefore, static electricity can be released to the reinforcing panel parts 110, 110 without being accumulated in the magnetic tape 101 or the sliding contact parts as in the conventional case. As a result, a natural discharge can be caused from the reinforcement panels 110, 110 into the air, and the user can
Even if it touches 0°110, there will be a discharge! Kotoka C kills. Therefore, it is possible to reduce magnetic deterioration of recordings or recorded magnetic material, thereby preventing spontaneous erasure of data or recorded contents. In addition, it is possible to prevent magnetic flux due to static electricity and dust from being transferred to the flol. In addition, the frictional heat generated by the high-speed running of the u3ki Larp 101 can be similarly conducted to the reinforced panel 110 and radiated naturally.
Due to the high-speed running of the magnetic door 101, the deformation of the magnetic door due to the heat generated by the cow is effective.

In the cassette tape case 200, when the cassette tape main body 100 is inserted and fixed into the cassette tape case 200, a portion corresponding to the voids 143, 143 formed in the cassette tape main body 100 is cut out and enters the capstan. A recess 208.208 is formed. Therefore, as shown in FIG. 8, by providing the recording/reproducing machine with a tape loading mechanism 300 that can press the magnetic tape 101 onto the rotary head 226, the magnetic tape 101 can be
It is also possible to take out the tape from the cartridge type cassette tape 1 and press it against the rotary head 226. That is, the tape loading mechanism 300 includes two loading arms 301, 301, and a loading arm 301.3.
The loading arm 301 is composed of an actuator (not shown) that can be rotated toward the front of the cassette tape main body 100 around the base end portions 305, 305 of the cassette tape body 100. When the cartridge-type cassette tape l according to this embodiment is loaded into a recorder/player, the leading end portion 304.

26, and as a result, the frequency band of the magnetic tape 101 can be significantly increased. Therefore, if the recorder/player is equipped with a tape loading mechanism 300 and a rotary head capable of recording, recording, and reproducing as shown in FIG. In addition, it can also be used for video recording. Furthermore, even when used for recording purposes, the frequency band can be significantly increased compared to conventional so-called compact cassette tapes, making it possible to greatly improve dynamic range, S/N ratio, etc. On the other hand, when storing recorded cassette tapes, the cassette tape body 100 may be stored in a fixed state inserted into the cassette tape case 200, or the cassette tape body 100 may be stored in the cassette tape case 200.

is pushed inward of the cassette tape case 200. As a result, the lock lever 212 rotates slightly clockwise around the shaft portion 217 against the biasing force of the spring 213, and the tip of the lock lever 212 Engagement claw 2 provided in

Since the cassette 00 is much smaller and thinner than conventional compact cassettes, it is possible to store a much larger number of recording media than conventional compact cassettes even in a small amount of space. In addition, in this embodiment, the cassette tape main body 100

The user can: By visually checking the meter section, the user can recognize the magnetic tape wrapped around the meter from specific numerical values at any time. Therefore, as in the past, by comparing the magnetic tape scraps remaining on the supply side hub with the magnetic tape scraps scraped off by the take-up side knob, Q remaining in
There is no need to judge whether or not the recording time will be exceeded, and it becomes possible to easily and visually recognize the tape residue remaining on the tape supply side.
